[0026] Please refer to the diagrams, where the same component symbols represent the same components. The principles of the invention are illustrated by way of example implemented in a suitable computing environment. The following description is based on the illustrative specific embodiments of the invention and should not be construed as limiting the invention to other specific embodiments not detailed herein.

[0027] See Figures 1 to 7 This invention provides a storage device 100, including a control circuit board 1, a first connector 2, a second connector 3, a card slot 4, and a memory board 5. The storage device 100 can be an OTG (On-The-Go) device, which can achieve communication connection with electronic devices such as computers, tablets, or mobile phones through the first connector 2 or the second connector 3 to realize data interaction.

[0028] The first connector 2 and the second connector 3 can be different types of communication interfaces. For example, the first connector 2 can be a Type-C interface, and the second connector 3 can be a USB interface, thereby enabling communication between the storage device 100 and electronic devices with different communication interfaces. Of course, the first connector 2 and the first connector 3 can also be the same type of communication interface, such as both being Type-C interfaces or both being USB interfaces; there is no limitation in this regard. The control circuit board 1 is equipped with a data processing circuit for realizing data interaction between the memory board 5 and the electronic device. The electronic device can be, for example, a computer, a mobile phone, or a tablet.

[0029] Among them, such as Figure 7As shown, the data processing circuit includes a USB HUB module 101, a handshake protocol module 102, and a MUX module 103. The USB HUB module 101 is electrically connected to the first connector 2 and the second connector 3, respectively. The memory board 5 is electrically connected to the USB HUB module 101 and the MUX module 103, respectively. The handshake protocol module 102 is electrically connected to the USB HUB module 101, and the MUX module 103 is electrically connected to the first connector 2 and the second connector 3, respectively, and is controlled by the USB HUB module 101 and the handshake protocol module 103.

[0030] Furthermore, the USB HUB module 101, as a core data and control signal relay unit, has one signal port connected to the handshake protocol module 102 to receive device handshake status signals and communication authorization commands output by the handshake protocol module 102; the data read / write port of the USB HUB module 101 establishes a bidirectional connection with the bidirectional data interface of the memory board 5 to send read / write control commands to the memory board 5, and simultaneously feed back the read / write status of the memory board 5 to the handshake protocol module 102; the external expansion ports of the USB HUB module 101 are connected to the first connector 2, the second connector 3, and the path control terminal of the MUX module 103, respectively, to realize data interaction between the external electronic device and the storage device 100, and to synchronize the path switching logic of the MUX module 103.

[0031] The handshake protocol module 102 is used to negotiate OTG roles (switching between host and slave modes), match communication rates, and authenticate identities with external electronic devices (including smartphones, tablets, computer hosts, etc.), generate corresponding handshake status signals and communication authorization instructions and transmit them to the USB HUB module 101, and at the same time receive the read and write status of the memory board 5 fed back by the USB HUB module 101 to dynamically adjust the stability of the communication link.

[0032] The memory board 5 serves as the core of data storage. It receives read and write control commands forwarded by the USB HUB module 101 and establishes data paths with the USB HUB module 101 and the MUX module 103 respectively through a bidirectional data interface. It is used to store user data (documents, audio and video files, etc.) and system control data (OTG protocol configuration parameters, handshake authentication information, path switching commands, etc.). It also supports fast writing, reading and erasing of data according to the read and write control commands of the USB HUB module 101.

[0033] The MUX module 103 serves as a data path selection unit. It is associated with both the USB HUB module 101 and the handshake protocol module 102. Based on the role negotiation result of the handshake protocol module 102 and the path switching command of the USB HUB module 101, it selectively enables the data path between the memory board 5 and external electronic devices, or between the USB HUB module 101 and external electronic devices, thereby enabling data reception and transmission switching when different external electronic devices are connected, and avoiding data transmission conflicts. Specifically, the MUX module 103 can be a high-speed multiplexer with two or more channels. Its path selection control terminal prioritizes receiving the role negotiation result signal (master mode / slave mode) output by the handshake protocol module 101, and combines it with the busy / idle status (read / write / idle) of the memory board 5 fed back by the USB HUB module 101 to achieve a path switching response within 10μs. When the external electronic device is in master mode, the MUX module 103 connects the data path between the memory board 5 and the external electronic device, directly receiving the data sent by the master and writing it to the memory board 5. When the external electronic device is in slave mode, the MUX module 103 connects the data path between the USB HUB module 101 and the external electronic device, forwarding the data stored in the memory board 5 to the slave device through the USB HUB module 101.

[0034] The first connector 2 and the second connector 3 are respectively located at both ends of the control circuit board 1; the card holder 4 is located on one surface of the control circuit board 1, and the card holder 4 has a memory slot 6 for placing the memory board 5. The two inner sidewalls of the memory slot 6 are fixedly connected to the limiting seat 8, and the side of the limiting seat 8 facing the memory slot 6 is fixedly connected to the spring piece 9 for limiting and fixing the memory board 5.

[0035] Furthermore, when the memory board 5 is inserted into the memory slot 6, it compresses the spring contacts 9 on both sides of the memory slot 6. This causes the spring contacts 9 to exert a reverse holding force on the memory board 5, thereby securing the memory board 5 within the memory slot 6. Different models of memory boards 5 may have different sizes; therefore, the degree of compression on the spring contacts 9 varies when different models of memory boards 5 are inserted into the memory slot 6, with larger memory boards exerting a greater degree of compression on the spring contacts 9. Through this method, the storage device 100 of the present invention can accommodate different models of memory boards 5, thus adapting to various models of memory boards 5 and improving the versatility of the storage device.

[0036] In this invention, both the limiting seat 8 and the spring contact 9 are conductive and electrically connected. The limiting seat 8 is electrically connected to the control circuit board 1, and the spring contact 9 is electrically connected to the memory board 5, thereby enabling the electrical connection between the memory board 5 and the control circuit board 1. Data interaction between the memory board 5 and electronic devices such as computers can be achieved through the first connector 2 or the second connector 3. The storage device 100 of this invention can communicate with an electronic device through the first connector 2 or the second connector 3, thereby enabling data interaction between the storage device 100 and the electronic device. Furthermore, the storage device 100 of this invention can also communicate with two electronic devices simultaneously through the first connector 2 and the second connector 3. For example, the first connector 2 can communicate with electronic device A, while the second connector 3 can communicate with electronic device B. Both electronic devices A and B can interact with the memory board 5, and electronic devices A and B can also interact with the storage device 100.

[0037] In some embodiments, the control circuit board 1 is provided with metal pins 11, and the card holder 4 has through holes (not shown) for conductive connectors to pass through. The metal pins 11 of the control circuit board 1 are electrically connected to the limiting seat 8 through the conductive connectors. The conductive connectors can be conductive wires or conductive metal sheets, and are soldered to the metal pins 11 for fixation. The USBHUB module 101 and the MUX module 103 are electrically connected to the memory board 5 through the metal pins 11.

[0038] In other implementations, such as Figure 4 As shown, the metal pin 11 is located between the card holder 4 and the second connector 3. A conductive groove 61 is provided on the inner bottom wall of the memory slot 6. One end of the conductive groove 61 extends to the limiting seat 8, and the other end of the conductive groove 61 extends to the side of the card holder 4 near the metal pin 11. A conductive connector is provided in the conductive groove 61. The limiting seat 8 and the metal pin 11 are electrically connected to the conductive connector to realize the electrical connection between the limiting seat 8 and the control circuit board 1.

[0039] Optionally, the conductive connector can be a conductive coating applied to the conductive groove, or it can be a conductive connecting wire or a conductive metal sheet.

[0040] Optionally, the limiting seat 8 and the spring 9 are integrally formed, and the connection between the limiting seat 8 and the spring 9 is arc-shaped. Both the limiting seat 8 and the spring 9 are made of beryllium copper alloy, which gives the spring 9 high elasticity. In addition, by making the connection between the spring 9 and the card seat 8 arc-shaped for transition, it is beneficial to avoid stress concentration during installation that could damage the spring 9 and extend its service life.

[0041] In some embodiments, a heat-insulating pad 41 is provided between the control circuit board 1 and the card holder 4, for example, Figure 5As shown, the heat insulation pad 41 can be disposed on the side of the card holder 4 facing the control circuit board 1. Alternatively, in other embodiments, the heat insulation pad can also be disposed on the surface of the control circuit board 1 facing away from the card holder 4. The heat insulation pad is made of ceramic fiber material, which can prevent the heat generated by the data processing chip from being directly transferred to the card holder 4 and the memory board 5, thus preventing the memory board 5 from throttling or being damaged due to high temperature.

[0042] In some implementations, such as Figure 6 As shown, the control circuit board 1 has several heat dissipation holes 13 at the position corresponding to the card holder 4. The heat dissipation holes 13 are distributed in an array to accelerate the dissipation of heat from the data processing chip itself. When the control circuit board 1 is provided with heat dissipation holes 13, a heat insulation pad 41 can be placed between the control circuit board 1 and the card holder 4.

[0043] In some embodiments, a limiting plate 7 is provided on the side of the card holder 4 near the first connector 2. The limiting plate 7 can block the insertion end of the memory board 5, define the installation depth, and prevent over-insertion from damaging the pins or chips. The continuous clamping force of the spring 9 and the blocking effect of the limiting plate 7 can improve the firmness of the memory board 5. Even if the storage device 100 vibrates, the risk of the memory board 5 loosening or falling off can be reduced.

[0044] In some embodiments, the control circuit board 1 is provided with a fixing hole 12, the second connector 3 has an extension piece 31, the extension piece 31 is provided with a snap-fit ​​member 32, one end of the control circuit 1 is stacked on the extension piece 31, and the snap-fit ​​member 32 is inserted into the fixing hole 12 to realize the connection between the control circuit board 1 and the second connector 3.

[0045] A storage device according to the present invention includes a control circuit board, a first connector, a second connector, a card holder, and a memory board. The first connector and the second connector are respectively disposed at both ends of the control circuit board and are electrically connected to the control circuit board. The card holder is disposed on one surface of the control circuit board and has a memory slot for placing the memory board. The two opposite inner sidewalls of the memory slot are fixedly connected to limit seats. A spring piece for limiting and fixing the memory board is fixedly connected to the side of the limit seat facing the memory slot. Through the action of the spring piece, different models of memory boards can be installed, thereby enabling the storage device to be compatible with multiple models of memory boards and improving the versatility of the storage device.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention.
