BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone, and more particularly to a slide type mobile phone in which two separately configured bodies slide automatically and manually with respect to each other.

In general, a mobile phone is a terminal that receives a mobile communication service that enables a part of a fixed local subscriber line to be used within a certain radius within a service area, and where a conventional communication service is fixed by a line number. On the other hand, the mobile phone can be used for communication without restriction in place by logical personal number regardless of line.

Such mobile phones are easy to carry and easy to use, and their demands are explosively increasing, and they are becoming smaller and more versatile to satisfy various needs of consumers.

In general, a mobile phone is roughly classified into a bar type, in which a keypad is exposed, a flip type in which a keypad is covered with a cover, and a folder type in which a body is folded in half. As shown in Fig. 1, a fold type in which a folder is opened with respect to the main body is dominant.

The folder 20 includes a speaker 22, a display window 24 for displaying various call information and function information, and other components.

In this folding type mobile phone, the folder 20 is hinged and fixed to the main body 10 by the cylindrical rotating unit 30, and the folder 20 is rotated in the forward or reverse direction about the rotating unit 30. The main body 10 is opened and closed.

That is, normally, the folder 10 is folded to shield the main body 10, and when making or receiving a call, the main body 10 is opened by rotating the folder 20.

However, such a clamshell mobile phone is inserted into a finger between the folder 20 and the body 10 to open and close the folder 20 in the body 10 when the folder 20 is folded in the body 10. There is inconvenience in using the folder 20 to be opened.

Of course, a mobile phone that automatically opens and closes the folder 20 has been developed to solve this inconvenience, but now, as these clamshell mobile phones are popularized, users may feel tired and require a new kind of mobile phones. .

The present invention was created in order to solve such a conventional problem, it is possible to facilitate the user's convenience by allowing the folder to slide up or down automatically or manually with respect to the main body, without hinge hinged relative to the main body, automatic sliding It is an object of the present invention to provide a sliding type mobile phone which can sense sliding motion at the time and end the sliding motion without manipulating a switch or a button.

Hereinafter, a mobile phone according to the present invention will be described with reference to the accompanying drawings.

2 is a perspective view illustrating a mobile phone according to an embodiment of the present invention, FIG. 3 is an exploded perspective view of the mobile phone shown in FIG. 2, and FIG. 4 is a partially cut away view of the mobile phone shown in FIG. 2. One side view.

5 is a front view showing a part of the mobile phone shown in FIG. 2, and FIG. 6A is an exploded perspective view showing the main parts of the mobile phone shown in FIG. 5, and FIG. 6B is an arm shown in FIG. 6A. Another embodiment of the type cam, and Figure 7 is a partial cutaway front view showing the operating state of the main portion during the manual sliding operation of the mobile phone shown in FIG.

The mobile phone according to the present invention as shown in Figs. 2 to 7 comprises a first body 50 and a second body 60 corresponding to the main body and the folder of the clamshell-type mobile phone described in the prior art. , The second body 60 is slidably coupled to the first body 50.

Here, looking at the first body 50, the first body 50 includes various components for transmitting and receiving, the speaker 52 and the battery pack (B) for power supply.

The first main body 50 further includes a display window 54 for displaying various call information and function information. In addition, the first main body 50 guides the sliding of the second main body 60, which will be described later, and the second main body ( And a switch SW for electrically controlling the sliding of 60.

In addition, the first body 50 is electrically connected to the switch (SW), one side is elastically supported by the elastic member 122, as shown in Figure 5, built in the first body 50 in the forward or Sliding means consisting of a motor (M) driven in the reverse direction, a pinion (P) rotated by the driving of the motor (M), and a power transmission unit (110) connecting the motor (M) and the pinion (P) to each other ( 100).

Here, the motor M is a geared motor provided with a planetary gear reducer having a reduction ratio of approximately 500 to 600: 1 so that the driving torque is amplified.

On the other hand, the pinion (P) receives the driving force of the motor (M) by the power transmission unit 110, this power transmission unit 110 is composed of a pair of members on both sides of the motor (M) and pinion (P). Each is connected.

In more detail, the power transmission unit 110 has a male cam 112 having a tapered protrusion on both sides, and a groove corresponding to the protrusion of the male cam 112, as shown in FIGS. 5 and 6A. It consists of a female cam 114.

And, the female cam 114 is connected to the rotation shaft (S) of the motor (M), the male cam 112 is connected to the shaft (sh) of the pinion (P), the female and male cams (114, 112) In this way, the driving force of the motor M is transmitted to the pinion P by being connected to the motor M and the pinion P.

These male and female cams (112, 114) are maintained in a mutually coupled state by the elastic member 112 described above to support the motor (M) elastically on one side, by this coupling the male cam 112 is a female cam ( 114).

That is, as the motor M is supported by the elastic force of the elastic member 112, the projection of the male cam 112 is inserted into the groove of the female cam 114, and the groove of the female cam 114 is the male cam 112. By constraining the projection of the male cam 112 is constrained.

Therefore, the male cam 112 is rotated together by the restraining force of the female cam 114 when the female cam 114 is rotated when the motor M is driven, and the male cam 112 is rotated by the rotation of the male cam 112. The driving force is transmitted to the pinion P.

Here, the groove of the female cam 114 may be formed in a "one" shape as shown in Figure 6a, alternatively may also be formed in a "double" shape as in the female cam 114 'of the other embodiment shown in Figure 6b. have.

On the other hand, the second body 60 includes a microphone 62, a keypad 64 made of various buttons and various components not shown, and is additionally inserted into the guide G of the first body 60. It further comprises a sliding rail (GR).

And, the second body 60 includes a rack (R) as shown in Figure 4 formed in a rectangular on one side, the rack (R) is in the pinion (P) that is interlocked with the motor (M) of the first body (50). It is formed at a position corresponding to the pinion P to be able to occlude.

Accordingly, the lecks R engage with the pinion P, the lecks R reciprocate by the rotation of the pinions P, and the second body 60 is the first body by the movement of the lecks R. Sliding with respect to 50.

On the other hand, when the first body 50 is opened to the first body 50 and the second body 60 by the sliding operation, the separation to prevent the second body 60 is separated from the first body 50 Preventing means is provided, the separation preventing means is composed of a projection-shaped stopper 56 protruding on the lower end of the first body 50 and a plate-like protruding piece 66 protruding on the upper end of the second body (60). do.

The stopper 56 and the protruding piece 66 face each other when the second main body 60 slides to open the first main body 50, and thus the second main body 50 is locked. Departure from the first body 50 is prevented.

On the contrary, when the second body 60 slides as described above to close the first body 50, the lower surface 65 of the second body 60 is the lower surface 55 of the first body 50. Sliding is completed by hitting the, so that the second body 60 is prevented from being separated from the first body 50.

That is, the second body 60 is not separated from the first body 60 because the lower surface 66 of the second body 60 is caught by the lower surface of the first body 50.

On the other hand, the completion of the sliding operation of the second body 60 can be detected by installing the sliding detection means (210, 212, 212 ') on the first body 50 and the second body 60, such sliding The sensing means 210, 212, 212 ′ are electrically connected to a control IC not shown to control the driving of the motor M. When the sliding completion is detected, the control IC automatically stops driving the motor M. The sliding action can be terminated automatically.

The sliding detecting means 210, 212, and 212 ′ may include two terminals 212 and 212 ′ installed at the top and bottom of the first body 50, respectively, as shown in FIG. 4, and an upper end of the second body 60. It is composed of one terminal 210 is installed to correspond to the two terminals (212, 212 '), each of these terminals 210 (212, 212') is a contact sensor that is switched in contact with each other It may be configured as a non-contact sensor that is configured or switched even when the contact is not.

Here, when the sliding detection means (210, 212, 212 ') is configured as a contact sensor, the terminals 212, 212' of the first body 50 should be configured as a switch terminal that is switched by pressing, The terminal 210 of the main body 60 should be composed of contact terminals in the form of minute protrusions that press the switch terminals.

And, when the sliding detecting means (210, 212, 212 ') is configured as a non-contact sensor, the terminals 212, 212' of the first body 50 is composed of Hall elements that are switched when the magnetic field is detected, the second body Terminal 210 of (60) should consist of a magnet that emits a magnetic field.

In the slide-type mobile telephone according to the embodiment of the present invention configured as described above, when the switch SW is operated for automatic sliding, the control IC, which is not shown, drives a signal to the motor M constituting the sliding means 100. Is applied to drive the motor (M).

At this time, the motor M is driven by the output torque is amplified by a reduction gear composed of a planetary gear therein, the elastic member 122 elastically supports the motor (M) in the expanded state in accordance with the drive of the motor (M) Maintain the coupled state of the delivery unit (110).

That is, the elastic member 122 elastically supports the motor M in the expanded state so that the female cam 114 of the power transmission unit 110 restrains the male cam 112.

Then, the driving force of the motor (M) by the coupling of the power transmission unit 110 is transmitted to the pinion (P) to rotate the pinion (P), by the rotation of the pinion (P) and the reciprocating (R) of the first The second main body 60 is slid relative to the main body 50.

Here, when the second body 60 is slid to open the first body 50, when the second body 60 completes the opening of the first body 50, the first and second bodies 5, The terminals 210 (212, 212 ') of the sliding sensing means (210, 212, 212') provided in 60 are switched to face each other.

Accordingly, the sliding detecting means 210, 212, 212 'stops the driving of the motor M by applying an electrical signal generated by switching to a control IC not shown, thereby sliding the second body 60. Ends.

Of course, even when the second body 60 is slid to close the first body 50, the sliding operation of the second body 60 is terminated by the same operation as in the opening.

That is, when the second body 60 completes the closing of the first body 50, the terminals 210 of the sliding sensing means 210, 212, and 212 ′ provided in the first and second bodies 5 and 60 ( 212 and 212 'are switched to face each other, whereby the control IC stops driving the motor M to end the sliding operation of the second body 60.

Here, the second body 60 is no longer sliding because the locking piece 66 of the second body 60 is caught by the stopper 56 of the first body 50 when the sliding operation for opening is completed. When the sliding operation for closing is completed, the lower surface 66 of the second body 60 is caught by the lower surface 55 of the first body 50 and no longer slides.

On the other hand, during the sliding operation of the second body 60, the operation of the rack (R) and the pinion (P) may generate noise in the mobile phone, in order to prevent the noise generated at this time (R) and pinion (P) ) Can be formed from a rubber material.

And, when the groove formed in the female cam 114 of the power transmission unit 110 is formed in the shape of a "two" shape as in the female cam 114 'according to another embodiment, the second body 60 is manually sliding. When the projection of the male cam 112 is taken once every 90 degrees by the groove of the female cam 114 '.

That is, since the projection of the male cam 112 is caught by the groove of the female cam 114 'every time it rotates 90 °, the total number of times is caught by the groove when rotating 360 °.

Therefore, the sound generated by the operation of the male and female cams 112 and 114 'when the second body 60 is slid is more frequently generated when the groove of the female cam 114 is formed to be “one”. Rather, the sliding action is smooth.

The above description has described a case in which the second main body 60 automatically slides. In contrast, the case in which the second body 60 slides manually is as follows.

First, when the user manually slides the second body 60, the rack R of the second body 60 is also slid, and the pinion P is rotated by the rack R.

Then, the male cam 112 of the power transmission unit 110 connected to the pinion P pushes the female cam 114 while rotating as shown in FIG. 7, and the female cam 114 slips by the tapered surface of the groove. Pressurize the motor (M).

At this time, the elastic member 122, which was elastically supporting the motor M, is compressed by the motor M being pressurized, and thus the motor M is pushed together with the female cam 114, and at the same time the male cam ( 112 is released from restraint of the female cam 114.

Accordingly, the male cam 112 is pivotally supported in the groove of the female cam 114 to rotate together with the pinion P, and the second body 60 is rotated by the pinion P to the first body 50. Slid manually.

That is, the second body 60 is the pinion (P) is rotated by sliding the male cam 112 is rotatable by the compression of the elastic member 122.

Of course, the rotation shaft S is not rotated by the motor M due to the separation of the male and female cams 112 and 114 by the compression of the elastic member 122.

Here, the main component that enables the sliding of the pinion (P) is the elastic member 122, the elastic member 122 is larger than the driving force of the motor (M) for sliding as described, the second body ( It should be designed to have less elastic force than the external force for sliding 60) manually.

Accordingly, the elastic member 122 may elastically support the motor M in the expanded state when the second body 60 is automatically sliding, and may be deformed in the compressed state when the manual sliding is performed to the motor M and the female cam ( 114).

FIG. 8 is a front view of a partially cut away mobile phone according to another embodiment of the present invention, and FIG. 9 is a side view of a partially cut away mobile phone shown in FIG. 8.

As shown, the mobile telephone according to another embodiment of the present invention includes a first body 50 and a second body 60, and the second body 60 is slidably movable with respect to the first body 50. Combined.

Here, the first body 50 generally includes various components for transmitting and receiving, a speaker 52 and a battery pack B for supplying power.

In addition, the first body 50 further includes a display window 54 for displaying various call information and function information. In addition, the guide G and the second body guiding the sliding of the second body 60 to be described later are described. And a switch SW for electrically controlling the sliding of 60.

The second body 60 includes a microphone 62, a keypad 64 made of various buttons, and various components not shown. The second body 60 is additionally inserted into the guide G of the first body 60. It further comprises a sliding rail (GR).

On the other hand, the switch (SW) is electrically connected to the sliding means for sliding the second body 60, the sliding means is a cylindrical motor (M) capable of forward and reverse rotation built into the first body (50) and , Wraps around the outer circumferential surface of the motor (M) and consists of a pulley 74 of rubber material attached thereto.

At this time, the pulley 74 is attached to the motor (M) is embedded in the first body 50, the outer peripheral surface portion so as to slide the second body 60 with a frictional force and a portion of the surface of the second body (60) It is installed in close contact.

The rotation shaft S of the motor M is fixed to a fixed portion formed of the female and male cams 82 and 80 and the elastic member 84, which will be described later, and is not rotated. Rather, since the rotation shaft S is fixed, the motor ( M) is rotated so that the pulley 74 rubs against the second body 60.

That is, when the power is applied to the motor M by operating the switch SW, the motor M is rotated based on the rotation shaft S, and as the motor M is rotated, the pulley 74 is secondly rotated. The second body 60 is slid with respect to the first body 50 by rotating while rubbing with the body 60.

Here, the motor M is preferably a geared motor having a planetary gear type reducer having a reduction ratio of approximately 500 to 600: 1 to generate a driving torque capable of sliding the second body 60.

In addition, a plurality of grooves (not shown) may be formed on the surface of the pulley 74 attached to the motor M in the longitudinal direction, the transverse direction, or the like, and a plurality of finely embossed protrusions may be formed.

On the other hand, the fixing portion for fixing the motor (M), one end is fixed to the rotation shaft (S) of the motor (M), the other end of the male cam 80 and the male cam 80 formed with projections having tapered on both sides, It has a groove corresponding to the projection, and the opposite end of the groove consists of a female cam 82 having a hollow one side is open.

At this time, the hollow of the female cam 82 is inserted in the expanded state of the elastic member 84, such as a compression coil spring is fixed to the inner surface of the first body 50, the arm by the elastic member 84 The type cam 82 is elastically supported.

The male cam 80 and the female cam 82 configured as described above are constrained from each other by the protrusion of the male cam 80 being inserted into the groove of the female cam 82, and the elastic member 84 supporting the female cam 82 is provided. It is possible to maintain the restraint state without being separated from each other by.

That is, the elastic member 84 elastically supports the female cam 82 to be coupled to the male cam 80, whereby the male cam 80 is constrained to the female cam 82 to rotate the shaft of the motor M ( Secure S).

Therefore, even if the rotation shaft S of the motor M rotates, the rotation shaft S is not rotated due to the male cam 80 constrained by the female cam 82, but rather, the motor is rotated about the fixed rotation shaft S. As the M rotates, consequently, the motor M becomes the rotor and the rotation shaft S becomes the stator.

In order to prevent the rotation of the rotating shaft (S), which is the stator, the female cam (82) must be able to overcome the rotational force of the rotating shaft (S) connected with the male cam (80). The supporting force of the member 84, that is, the elastic force, should be larger than the rotational force of the rotation shaft S.

In other words, the elastic member 84 should be applied to the one having a larger elastic force than the driving force of the rotating shaft (S).

However, the elastic member 84 should have a larger elastic force than the driving force of the rotating shaft (S), but this elastic force should be an elastic force that can be compressed when the external force is transmitted to the second body 60 to slide.

That is, when the user manually slides the second body 60, the elastic member 84 should be compressed so as to prevent damage of the male and male cams 82 and 80.

In more detail, when the second body 60 is slid by manual operation, the pulley 74 and the motor M in close contact with the second body 60 rotate, and the motor M The rotating shaft S of) is also rotated.

Then, the male cam 80 connected to the rotating shaft S is also rotated to rotate the female cam 82 that is constrained to each other, and the elastic member 84 is compressed to restrain the male cam 80 and the female cam 82. Release it.

If the elastic member 84 is not compressed, the female cam 82 continues to restrain the male cam 80, thereby making it impossible to slide the second body 60, and the load caused by the external force is reduced. The male and female cams 80 and 82 are broken by being generated in the female cams 80 and 82.

However, when the elastic member 84 is compressed to release the restraints of the male cam 80 and the female cam 82, the projections of the male cam 80 pivot out of the grooves of the female cam 82 and are smoothly supported in the grooves. It rotates smoothly.

Therefore, by compressing the elastic member 84, the second body 60 can be manually slidable.

Here, reference numeral 86 in the figure not described is a ring-shaped bearing which is fitted to one side of the motor M to rotatably support the motor M and smoothly rotates the motor M.

On the other hand, by providing a position detecting means for detecting the sliding state of the second body 60 with respect to the first body 50 can be automatically controlled to drive the motor (M).

The position detecting means is installed on one side of the motor (M), as shown in Figure 9 rotates, and is installed in a position facing the projection 92 to detect the rotation state of the projection 92 It consists of a position sensor 94.

At this time, the position detection sensor 94 may be a switch type in contact with the projection 92, or alternatively, a photo sensor for detecting the projection 92 with a laser may be applied, and the installation position thereof may also include the projection ( The inner side of the first body 50 corresponding to 92, or one side of the female cam 82 is not rotated.

Of course, the position sensor 94 is connected to the IC (not shown), the IC can control the power of the motor (M) by calculating the number of revolutions of the projection (92).

That is, since the rotation speed of the protrusion 92 is the number of rotations of the motor M, the IC detects the sliding state of the second body 60 according to the rotation of the motor M, that is, the opening and closing state of the first body 50. It is possible to supply and cut off the power of the motor (M) accordingly.

On the other hand, unlike the above-described position detection means as shown in FIG. 9, the magnet 92a is provided on the upper and lower portions of the second body 60, and the magnet of the magnet 92a is provided on one side of the first body 50; It may be configured as a magnetic sensor 94a for detecting.

When the position detecting means is configured as described above, when the second body 60 is slid by the sliding means and the magnet 92a and the magnetic sensing sensor 94a coincide with each other, the IC connected to the magnetic sensing sensor 94 is connected to the motor M. The driving of the is controlled.

Therefore, the second body 60 may slide the first body 50 to accurately open and close the first body 50.

As described above, the mobile phone according to another embodiment of the present invention implements sliding of the second main body 60 by the sliding means composed of the motor M and the pulley 74, but as shown in FIG. As described above, sliding may be implemented according to another embodiment of the present invention.

Referring to the drawings, FIG. 10 is a front view illustrating a portion of a mobile telephone according to another embodiment of the present invention. The mobile telephone according to another embodiment is largely inward of the first body 50. A friction member 300 which is fixed to the motor M ', the power transmission units 80' and 82 'connected to the motor M', and the second body 60 to slide the second body 60. )

At this time, the motor (M ') is formed in the form of a hexahedron is embedded in the interior of the first body 50, the rotating shaft (S') made of the male and female cams (80 ', 82') as described above. The power transmission unit is connected, and an elastic member 84 'such as a compression coil spring is installed at an opposite end of the rotation shaft S' in an expanded state.

Of course, one side of the elastic member 84 'is fixed to the motor (M'), the other side is fixed to the inner surface of the first body 50 to support the motor (M ') elastic, thereby male and female cam 80 'and 82' are bound to each other.

On the other hand, the friction member 300 for sliding the second body 60 may be configured as a pulley of a rubber material attached to surround the outer circumferential surface of the female cam 80 'as shown, unlike the female cam 82 ') Can be configured as a separate rubber roller (not shown) fixed to.

In addition, a groove may be formed on the surface of the friction member 300 so as to improve the friction force, or a finely embossed protrusion may be formed.

Of course, the friction member 300, such as the pulley 74 described in the above description, is configured such that a portion is in close contact with the surface portion of the second body 60 to slide the second body 60.

The friction member 300 is provided on one side or both sides to support the friction member 300, it is smoothly rotated by a fixing member 88 made of a ring-shaped bearing rotatably supporting.

When the mobile phone according to another embodiment configured as described above is driven by an external power source and the stator motor M 'is rotated, the rotating shaft S', which is the rotor, is rotated to rotate the male and female cams 80 'and 82'. Therefore, the friction member 300 integrally with the female cam 82 'is also rotated.

Then, the friction member 300 is rubbed with the second body 60 while rotating to slide the second body 60.

In this case, in order to automatically control the sliding main body 60, a position detecting means should be provided, and the position detecting means has a projection (S ') installed on the rotation shaft S' of the motor M 'as shown in FIG. 92 ') and the position detecting sensor 94' provided on the inner surface of the first body 50 corresponding to the protrusion 92 '.

Of course, the position sensor 94 'may be installed on one side of the motor M', which is a portion indicated by a dotted line in the figure, not on the inner surface of the first body 50.

As shown in FIG. 4, the position detecting means includes a magnet 92a provided at an upper portion and a lower portion of the second body 60, and a magnetic sensing sensor provided at the first body 50 corresponding to the magnet 92a. It can also be set to 94a.

Here, since the position detecting means configured as described above has already been described in the above description of FIG. 9, it will not be described in detail.

Subsequently, in the mobile telephone according to another embodiment of the present invention, the elastic member 84 'provided at one side of the motor M' may rotate the friction member 300 even when the second body 60 is slid. ') Is continuously supported to maintain the male and female cams (80', 82 ') restrained state.

However, the elastic member 84 'is compressed to release the male and female cams 80' and 82 'from restraint when the second body 60 is slid by an external force.

That is, when the second body 60 is slid by the external force, the female cam 82 'is rotated, and the elastic member 84' is compressed by the external force greater than the rotational force of the motor M 'to compress the male cam 80. ') And the female cam (82') is released.

In other words, the female cam 82 'is rotated by an external force, and the male cam 80' is not rotated, so that the male cam 80 'is tapered by the female cam 82'. Sliding back.

The motor M 'is also retracted while the male cam 80' is retracted, and the motor M 'is retracted along the inner surface of the first body 50 to compress and compress the elastic member 84'. .

Of course, the elastic member 84 'is preferably larger than the driving force of the rotation shaft (S') of the motor (M '), so as to enable automatic and manual sliding of the second body 60, it has a smaller elastic force than the external force.

The above embodiment is merely a description of the preferred embodiment of the present invention, the scope of application of the present invention is not limited to such, and can be changed as appropriate within the scope of the same idea.

Therefore, the shape and structure of each component shown in the embodiment of the present invention can be carried out by modifying, it is natural that the modification of the shape and structure belong to the appended claims of the present invention.

As described above, according to the mobile phone according to the present invention, since the second body is automatically and manually slid by the sliding means provided with the rack and pinion or the friction member, it can be used more conveniently than the conventional clamshell phone.
