[0030] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0031] Firstly, referring to Figure 1 and Figure 2 , Figure 1 This is a module diagram of a data cable with card reading function provided in an embodiment of the present invention. Figure 2 This is a circuit diagram of a data cable with card reading function provided for an embodiment of the present utility model.

[0032] It is understood that the data cable with card reading function provided in this utility model includes a first data interface 100, a second data interface 200, a control module 300, and a card reading module 400. The first data interface 100 includes a first power supply terminal 110, a first data transmission terminal, and a first signal detection terminal 140. The second data interface 200 includes a second power supply terminal 210, a second data transmission terminal, and a second signal detection terminal 240. The first power supply terminal 110 is connected to the control module 300 and the second power supply terminal 210, respectively. The first data transmission terminal is connected to both the control module 300 and the second data transmission terminal, respectively. The first signal detection terminal 140 is connected to the control module 300, and the second signal detection terminal 240 is connected to the control module 300. The control module 300 is connected to a first power supply terminal 110 and a second power supply terminal 210. When the first data interface 100 is connected to an external device, the control module 300 can obtain the required operating voltage through the first power supply terminal 110; and when the second data interface 200 is connected to an external device, the control module 300 can obtain the required operating voltage through the second power supply terminal 210. The control module 300 is also connected to a first signal detection terminal 140 and a second signal detection terminal 240. When the first data interface 100 is connected to an external device, the control module 300 can transmit data to the external device connected to the first data interface 100 through the first data transmission terminal; and when the second data interface 200 is connected to an external device, the control module 300 can transmit data to the external device connected to the second data interface 200 through the second data transmission terminal. The control module 300 can determine whether the first data interface 100 is connected to an external device based on the level signal obtained from the first signal detection terminal 140; similarly, the control module 300 can determine whether the second data interface 200 is connected to an external device based on the level signal obtained from the second signal detection terminal 240. The control module 300 is connected to the card reader module 400. When the memory card is installed in the card reader module 400, the control module 300 can obtain the data of the memory card through the card reader module 400, and then transmit the data to the external device connected to the first data interface 100 through the first data interface 100, or transmit the data to the external device connected to the second data interface 200 through the second data interface 200.

[0033] It should be noted that when the first data interface 100 and the second data interface 200 are simultaneously connected to different external devices, the first signal detection terminal 140 will send a level signal indicating the connection between the first data interface 100 and the external device to the control module 300, and the second signal detection terminal 240 will send a level signal indicating the connection between the second data interface 200 and the external device to the control module 300. When the first data interface 100 and the second data interface 200 are simultaneously connected to different external devices, and the two external devices may be in a charging or data interaction state, the control module 300 can stop sending signals through the first data transmission terminal and the second data transmission terminal to avoid data conflicts. Even if the card reader module 400 has a memory card installed, the control module 300 will not send signals through the first data transmission terminal and the second data transmission terminal when the first data interface 100 and the second data interface 200 are simultaneously connected to external devices.

[0034] It should be noted that when the first data interface 100 is connected to an external device and the card reader module 400 is equipped with a memory card, the control module 300 can transmit the data of the memory card to the external device through the first data transmission terminal. Similarly, when the second data interface 200 is connected to an external device and the card reader module 400 is equipped with a memory card, the control module 300 can transmit the data of the memory card to the external device through the second data transmission terminal.

[0035] Specifically, the first data interface 100 and the second data interface 200 are the same data interface. In some embodiments, the first data interface 100 and the second data interface 200 are both Type-C interfaces. By setting the first data interface 100 and the second data interface 200 as Type-C interfaces, reversible blind insertion and bidirectional connection can be realized, improving the user experience.

The voltage conversion module 500 can convert the voltage input from the first power supply terminal 110 and / or the second power supply terminal 210 into the operating voltage required by the control module 300 and the card reading module 400, thereby improving the operational stability of the data cable with card reading functionality.

[0037] It is understood that in some embodiments, the data cable with card reading function also includes a first prompt module 310, which is connected to the control module 300.

For example, the first prompt module 310 is an LED light. When the first data interface 100 and the second data interface 200 are connected to different external devices at the same time, the control module 300 can control the LED light to stay on. When the first data interface 100 is connected to an external device and the card reader module 400 has a memory card installed, or when the second data interface 200 is connected to an external device and the card reader module 400 has a memory card installed, the control module 300 can control the LED light to flash.

When the card reading module 400 is in different operating states, it can change the operating state of the second prompt module 420, allowing the user to intuitively understand the operating status of the card reading module 400. For example, if the second prompt module 420 is an LED light, when a memory card is installed in the card reading module 400, the card reading module 400 can control the LED light to remain on; when no memory card is installed, the card reading module 400 can control the LED light to turn off.

The voltage input from the first power supply terminal 110 and / or the second power supply terminal 210 can be converted into the voltage required for the operation of the card reader chip U2 and the control chip U1 by the voltage conversion chip U3. By connecting capacitors in parallel at the input and output terminals of the voltage conversion chip U3, the input and output voltages can be filtered to improve the working stability of the data line.

The first DP input terminal DP1 is connected to the second DP output terminal DP2, and the first DM input terminal DM1 is connected to the second DM output terminal DM2.
