Detailed Description
Fig. 1 is a schematic diagram of a flash disk according to an exemplary embodiment of the invention. Fig. 2 to 4 are schematic diagrams illustrating a process of converting the flash disk of fig. 1 into another state. In order to further understand the corresponding relationship between the related components, a part of the internal components of the flash disk is drawn with a dotted line. Referring to fig. 1 to 4, in the present exemplary embodiment, the flash disk 100 includes a storage module 110, a switch module 120, and a switching mechanism 130. The memory module 110 can be regarded as a main structure of the flash disk 100, and has a first body 112, a memory unit 114 and a first interface module 116, wherein the memory unit 114 is, for example, a flash memory unit, and can be packaged together with a related control element, a memory element and a circuit board (not shown In this exemplary embodiment) by a System In Package (SIP) technology and using plastic, metal, ceramic material or epoxy resin to form a Package mode of System integration so as to protect these electronic elements In the Package structure. The first interface module 116 is electrically connected to the storage unit 114 and protrudes out of the first body 112, so that the storage unit 114 of the storage module 110 can be connected to other electronic devices by using the first interface module 116 as its transmission interface.
Furthermore, the adaptor module 120 has a second interface module 122 and a third interface module 124 which are different in form but electrically connected to each other, wherein the second interface module 122 corresponds to the first interface module 116 of the memory module 110. The term "mutually corresponding" as used herein means that two interface modules can be connected to each other in terms of their structural and electrical relationships. The switching mechanism 130 is movably assembled to the storage module 110, and the patching module 120 is disposed in the switching mechanism 130. In this way, when the conversion mechanism 130 is assembled to the memory module 110 and rotates to the first position P1 (shown in fig. 1) by a proper angle, the first interface module 116 and the second interface module 122 are correspondingly connected to each other, so that the memory unit 114 is electrically connected to the third interface module 124 through the second interface module 122, and thus the memory unit 114 is connected to a host of another electronic device by using the third interface module 124 as its transmission interface. Conversely, when the adaptor module 120 is moved away from the first interface module 116 of the memory module 110 by the switching mechanism 130 to reach the second position P2 (shown in fig. 4), the memory unit 114 resumes the first interface module 116 as its transmission interface. Accordingly, the memory module 110 can have different transmission interfaces (such as switching between the first interface module 116 and the third interface module 124) by the movement change of the switching mechanism 130.
In the present exemplary embodiment, the first interface module 116 and the third interface module 124 are plugs, respectively, and the second interface module 122 is a socket. Further, the first interface module 116 of the present example embodiment is a Universal Serial Bus (USB) plug, the second interface module 122 is a USB socket, and the third interface module 124 is a micro-USB plug. The first interface module 116 is electrically connected to the memory unit 114 by, for example, packaging or soldering, so as to serve as a use mode of the memory module 110 in the first state (as shown in fig. 4). When the switch mechanism 130 is sequentially connected to the memory module 110 as shown in fig. 4, 3 to 2, the second interface module 122 of the switch module 120 in the switch mechanism 130 is correspondingly connected to the first interface module 116, so that the memory unit 114 is in the second state (as shown in fig. 1) and serves as a transmission interface through the third interface module 124 (micro-universal serial bus plug).
Referring to fig. 4 again, the first body 112 of the present exemplary embodiment is a rectangular parallelepiped structure as shown in fig. 4, and has a pair of sliding slots 112a located on a pair of side surfaces S1, S2, and the first interface module 116 protrudes from the front surface S3 of the first body 112, wherein the front surface S3 is abutted between the pair of side surfaces S1, S2. Furthermore, the conversion mechanism 130 includes a second body 132 and a cover 134, wherein the second body 132 has a lip 132a and a pair of extension arms 132b, 132c extending away from each other. The cover 134 is slidably engaged with the lip 132a of the second body 132. An end of each extension arm 132b, 132c away from the lip 132a is slidably pivoted in the sliding slot 112a of the first body 112. In the present embodiment, only the chute 112a on one side of the first body 112 is shown as a representative.
Referring to fig. 1 to 4, by the extension arms 132b and 132c cooperating with the sliding slot 112a, the second body 132 can rotate back and forth along the direction D1 and slide back and forth along the direction D2 relative to the memory module 110. When the second body 132 rotates to the position shown in fig. 3, it can slide along the direction D2 again, so that the second body 132 and the first body 112 are sleeved with each other, and the extension arms 132b, 132c completely cover the side surfaces S1, S2, respectively, so that the second body 132 and the first body 112 are integrated into a single rectangular parallelepiped, as shown in fig. 2, that is, the second body 132 can be regarded as an extension of the first body 112 in structure. On the contrary, when the first interface module 116 is not yet mated with the second interface module 122, the first body 112, the second body 132 and the pair of extension arms 132b and 132c together form a structure surrounding all sides and having opposite openings (as shown in fig. 3 and fig. 4).
In addition, the cover 134 and the lip 132a are slidably received over each other to transition between an extended state (as shown in fig. 2 or 3) and a shortened state (as shown in fig. 1). The cover 134 has an opening 134a, when the second body 132 is sleeved to the first body 112, that is, the second interface module 122 of the adaptor module 120 is connected to the first interface module 116, the opening 134a is aligned with the third interface module 124 located in the second body 132, and when the cover 134 slides toward the extension arms 132b, 132c along the direction D2 to cover the lip 132a, the third interface module 124 protrudes out of the cover 134 through the opening 134 a. Then, the switching mechanism 130 moves to the first position P1 relative to the memory module 110, so that the first body 112, the second body 132 and the cover 134 form an integrated housing structure, and the protruding third interface module 124 serves as a transmission interface of the flash disk 100 for electrically connecting with a host of another electronic device.
Conversely, to resume using the first interface module 116 as the transmission interface of the flash disk 100, the cover 134 is slid along the direction D2 away from the extension arms 132b and 132c, and then the second body 132 is driven to slide away from the first body 112 along the direction D2, so that the second interface module 122 can exit the first interface module 116, and then the first interface module 116 can be exposed and used after the second body 132 is rotated along the direction D1 to the second position P2.
Fig. 5 and 6 are schematic diagrams illustrating a patching module in the flash disk of fig. 1 from different perspectives, respectively. Referring to fig. 5 and fig. 6, the adaptor module 120 of the present exemplary embodiment further includes a third body 126 and a connecting circuit 128. The third body 126 has a first end E1 and a second end E2 opposite to each other, the second interface module 122 is disposed at the first end E1, the third interface module 124 is disposed at the second end E2, and the connection circuit 128 is disposed on the third body 126 and electrically connected between the second interface module 122 and the third interface module 124.
Further, the third body 126 further has a first surface S4 and a second surface S5 opposite to each other, the second interface module 122 includes a plurality of terminals T1 to T4, and the third interface module 124 includes a plurality of terminals M1 to M5. For example, the terminals T1 to T4 of the exemplary embodiment are the power terminal (VBUS), the differential signal terminal (D +/D-) and the ground terminal (GND) conforming to the usb interface, respectively, and the terminals M1 to M5 are the power terminal (VBUS), the differential signal terminal (D +/D-), the identification terminal (ID) and the ground terminal (GND) conforming to the micro usb interface, respectively.
The connection circuit 128 includes a plurality of wires W1 to W4 respectively disposed on the first surface S4 and the second surface S5, wherein the wires W1 to W3 on the first surface S4 are respectively connected to the terminals T1, T3, T4 and M1, M3, and M5, and the wire W4 on the second surface S5 is connected to the terminals T2 and M2. This allows the third body 126 to have a surface area that is sufficiently utilized for the arrangement of the connecting circuit 128, thereby providing a light, thin, short and small appearance. In addition, it can also be known from the present exemplary embodiment that the number of terminals of the second interface module 122 is different from the number of terminals of the third interface module 124, so that at least one terminal (here, the terminal T2 is taken as an example) of the second interface module 122 is not electrically connected to the third interface module 124. Similarly, in another embodiment not shown, at least one terminal of the third interface module may not be electrically connected to the second interface module.
Fig. 7 to 9 are schematic diagrams illustrating a state transition of a flash disk according to another exemplary embodiment of the invention. Referring to fig. 7 to 9, in the present exemplary embodiment, unlike the above, the switching mechanism 220 of the flash disk 200 is detachable, that is, it is detachably assembled on the memory module 210. Further, the switching mechanism 220 includes a second body 222 and a cover 224, wherein the second body 222 is adapted to be sleeved to the first body 214 of the storage module 210, so that the first interface module 212 can be correspondingly connected to a second interface module (not shown) of the adaptor module 230. Afterwards, the cover 224 is slidably sleeved on the second body 222 and has an opening 224a corresponding to the third interface module 232. Therefore, when the cover 224 slides towards the first body 214 and covers the second body 222, the state shown in fig. 8 is switched to the state shown in fig. 7, so that the switching mechanism 220 moves to the first position P3 relative to the memory module 210, and therefore the third interface module 232 protrudes out of the cover 224 through the opening 224a, so that the memory module 210 can be electrically connected to a host of another electronic device by using the third interface module 232 as its transmission interface. In contrast, once the switching mechanism 220 moves to the second position relative to the memory module 210, i.e. in the present exemplary embodiment, the switching mechanism 220 moves away from the memory module 210, the memory module 210 can be used as a transmission interface for electrically connecting to a host of other electronic devices through the first interface module 212.
The form of the interface module is not limited, that is, in the present exemplary embodiment, other interface modules than the third interface module 232 may be used as the output portion of the adaptor module, and the first interface module 212 may use other form of interface module as its transmission interface instead.
In summary, in the above exemplary embodiments of the invention, the flash disk changes the state between the conversion structure and the storage module, so that the storage module can utilize the adapter module disposed in the conversion structure to connect with the first interface module, and the storage module can utilize the third interface module instead of the first interface module as its transmission interface, in addition to the first interface module originally provided by the storage module as its transmission interface. Therefore, no matter the assembly form of the conversion mechanism can be changed or the assembly form of the conversion mechanism can be disassembled, the storage module can be matched with the conversion mechanism to be applied to transmission interfaces of different electronic devices, so that the application range of the storage module is effectively expanded.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
