[0034] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0035] In order to better understand the technical solutions of the present application, the following will be described in detail in combination with the drawings in the specification and specific embodiments.

[0036] The main solution of the embodiment of the present application is:

[0037] Since in the fields of computers and mobile devices, the mouse, as one of the most commonly used pointer input devices, its security and anti-theft function are particularly important. However, sometimes wired mice need to be used in public places, and wired mice are connected to the USB ports on the computer host through USB interfaces. Due to this simple and easy-to-disassemble connection method, in public places such as Internet cafes, office buildings, and libraries, although there are monitors in such scenarios for supervision, the monitoring personnel cannot always closely monitor the monitoring equipment and cannot evaluate the status of the mouse socket. Therefore, the mouse may be stolen, which greatly increases the user cost.

[0038] The present application provides a solution. The wired anti-theft mouse detects whether the mouse is pulled out from the USB interface through a pull-out detection unit. When pulled out, the first wireless communication circuit can send a warning to external monitoring personnel, and can detect whether the wired anti-theft mouse is within the communication range through the communication status of the first wireless communication circuit with the outside world, and find out whether the user is debugging or stealing the mouse. Therefore, the monitoring personnel can view through the warning sent by the wired anti-theft mouse, either through the monitoring device or by walking to the location of the warning mouse, and can find out whether the user is debugging or stealing the mouse by whether the wired anti-theft mouse is within the communication range, thus solving the problem that the mouse is often stolen in public places.

[0039] The present application provides a solution, referring to Figure 1 and Figure 2 , to make a wired anti-theft mouse. The wired anti-theft mouse is provided with a USB interface 7. The wired anti-theft mouse A includes:

[0040] A first wireless communication circuit 4;

[0041] A pull-out detection circuit 3. The pull-out detection circuit 3 is arranged in the USB interface 7. The pull-out detection circuit 3 is electrically connected to the main controller 1 and is used for generating a detection signal when it detects that the USB interface 7 is pulled out from the connected device and sending the detection signal to the main controller 1;

[0042] The main controller 1 is electrically connected to the first wireless communication circuit 4. The main controller 1 is used for sending a warning signal of the warning state to an external terminal through the first wireless communication circuit 4 according to the detection signal, receiving a scanning signal of the communication status of the external controller of the connected device through the first wireless communication circuit 4, and outputting a connection confirmation signal to the external controller through the first wireless communication circuit 4 when the wired anti-theft mouse is not disconnected from the external controller;

[0043] An energy storage component 2. The energy storage component 2 is electrically connected to the main controller 1 and is used for providing a backup power supply to the main controller 1 when the USB interface is pulled out from the connected device.

[0044] In this embodiment, the unplug detection circuit 3 can be implemented by means of an optical proximity chip WHAPS 4530A, an inductive proximity chip LDA355, an infrared detection chip WH4535V, etc. The first wireless communication circuit 4 can communicate with the outside world by using one or more of a Bluetooth communication chip, a WIFI communication chip, an infrared communication chip, and a ZIGBEE communication chip. The main controller 1 can be implemented by using, for example, an MCU (Microcontroller Unit), a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), or a SOC (System On Chip) with a 5V voltage input such as an ESP32-C3 chip. The energy storage component 2 can use a lithium rechargeable battery or a dry battery for energy storage, and can also integrate intelligent charging and discharging management functions, enabling the energy storage component 2 to be charged according to the USB interface 7. Thus, when the USB interface 7 of the wired anti-theft mouse A is unplugged, the unplug detection circuit 3 sends a detection signal to the main controller 1, and the main controller 1 sends a warning to the monitoring personnel through the first wireless communication circuit 4. Moreover, the first wireless communication circuit 4 can receive and detect a scanning signal of the communication status between the wired anti-theft mouse A and the external controller B, or send a confirmation signal. The main controller 1 generates a confirmation signal through the scanning signal, so that the monitoring personnel can judge whether the person unplugging the wired anti-theft mouse A is performing debugging or theft by monitoring the communication status between the wired anti-theft mouse A and the external controller B.

[0045] In this embodiment, as Figure 2 shown, the USB interface 7 is provided with a serial port 8 and a housing 11. One end surface 10 is connected between the serial port 8 and the housing 11, and a detection hole 9 of the unplug detection circuit 3 is provided on the end surface 10, so that when the USB interface 7 is unplugged, the unplug detection circuit 3 detects the unplugging of the USB interface 7 through the detection hole 9.

[0046] As can be seen from the above embodiment, through the warning of the wired anti-theft mouse A and the communication status between the wired anti-theft mouse A and the external controller B, the monitoring personnel can timely monitor according to the warning and judge whether the person unplugging the wired anti-theft mouse A is debugging the mouse or preparing to steal based on whether the communication status is disconnected.

[0047] In one embodiment, the wired anti-theft mouse A further includes:

[0048] The prompting circuit 5 is electrically connected to the main controller 1. The main controller 1 is further configured to generate a prompting signal to the prompting circuit 5 when the USB interface is unplugged, so that the prompting circuit 5 emits a prompting message to prompt the user.

[0049] In this embodiment, the prompting circuit 5 can be implemented by one or more of a buzzer, a light, a voice, a vibration, etc., so as to better remind the user that the USB interface 7 has been unplugged and is in a warning state. When the USB interface 7 is unplugged, the main controller 11 will detect this state change and generate a corresponding prompting signal. After receiving the prompting signal, the prompting circuit 5 will immediately trigger the corresponding prompting method, such as the buzzer emitting a sound, the light flashing, a voice prompt or a vibration, etc., to prompt the person who unplugged the wired anti-theft mouse A and avoid the risk of the user unplugging the mouse resulting in the loss or theft of the device.

[0050] In one embodiment, the wired anti-theft mouse further includes:

[0051] A timer 6, the timer 6 is electrically connected to the main controller 1, and is configured to generate a timing signal at a fixed interval and send it to the main controller 1;

[0052] The main controller 1 is configured to generate a start detection signal according to the received timing signal and send it to the unplugging detection circuit 3 to control the unplugging detection circuit 3 to detect the connection state of the USB interface.

[0053] In this embodiment, the timer 6 can be implemented by means of an internal timer of a microcontroller, a hardware timer chip, a real-time clock (RTC) module, an external crystal oscillator or an oscillator, etc., so that the wired anti-theft mouse can generate a timing signal at a fixed interval, enabling the main controller 11 to control the unplugging detection circuit 33 to perform detection according to the timing signal.

[0054] Specifically, the timer 6 can be programmed by the internal timer of the ESP32-C3 chip to generate a timing signal at a fixed interval. After being sent to the processor in the ESP32-C3 chip, a start detection signal is generated and sent to the unplugging detection circuit 3, thereby controlling the unplugging detection circuit 3 to perform detection. It can also process the detection signal generated by the unplugging detection circuit 3 through the ESP32-C3 chip and generate the warning signal to be sent to the outside through the internal Bluetooth unit; the timer can also be implemented by a specific circuit such as Figure 3 As shown, the timer 6 is provided with a passive crystal oscillator as a clock source and is programmed with a PCA8563 clock chip, so that the timer 6 generates a timing signal at a fixed interval.

[0055] Thus, the wired anti-theft mouse A can generate a timing signal at fixed intervals through the timer 6 and send it to the main controller 1, controlling the intermittent operation of the unplugging detection circuit 3 to achieve the effect of reducing power consumption.

[0056] This application also provides an anti-theft system. Refer to Figure 4 , the anti-theft system includes the wired anti-theft mouse as described above and an external controller B, and more than one wired anti-theft mouse A is communicatively connected to the external controller B.

[0057] In an embodiment, the external controller B includes:

[0058] A control unit 12, configured to generate a scanning signal, and also configured to generate a warning status prompt signal according to the received warning signal, and also configured to generate a determination status prompt signal according to the determination signal;

[0059] A second wireless communication circuit 13, the second wireless communication circuit 13 is communicatively connected to the first wireless communication circuit 4, the second wireless communication circuit 13 is electrically connected to the control unit 12, and is configured to receive each mouse warning signal and determination signal, and is also configured to send a scanning signal;

[0060] A status prompt circuit 14, the status prompt circuit 14 is electrically connected to the control unit 12, and is configured to receive the warning status prompt signal and the determination status prompt signal, and prompt the warning status and communication status of each wired anti-theft mouse.

[0061] In this embodiment, the second wireless communication circuit 13 can adopt one or more of a Bluetooth communication unit, a WIFI communication unit, an infrared communication unit, and a ZIGBEE communication unit. Among them, at least one communication method of the second wireless communication circuit 13 can communicate with the first wireless communication circuit 4; the status indication circuit 14 can be implemented by means of a plurality of LED lights and voice, etc. The control unit 12 can be implemented by adopting a main controller 1, such as an MCU (Microcontroller Unit, micro control unit 12), a DSP (Digital Signal Process, digital signal processing chip), an FPGA (Field Programmable Gate Array, programmable logic gate array chip), such as an SOC (System On Chip, system-level chip), etc. to implement; when the second wireless communication circuit 13 receives a warning signal, the control unit 12 generates a warning status indication signal according to the received warning signal and sends it to the status indication circuit 14 to indicate the warning status of each of the wired anti-theft mice A. The control unit 12 can also generate a scanning signal and send it to the second wireless communication circuit 13, so that the second wireless communication circuit 13 scans each of the wired anti-theft mice A, and according to the returned determination signal, the control unit 12 generates a determination signal to control the status indication circuit 14 to give an indication of the communication status determination online of each of the wired anti-theft mice A. Among them, a unique hardware address or ID can be assigned to the signals received by each of the wired anti-theft mice A. The external controller B identifies the signals of the source device by reading this address. Thus, the control unit 12 can generate corresponding warning status signals and determination signals to give an indication to the status indication circuit 14. Therefore, the external controller B can generate different indication signals according to the warning status of each wired anti-theft mouse and the communication status between the wired anti-theft mouse A and the external controller B, and design the status indication circuit 14 with a plurality of different LED lights and give an indication to the monitoring personnel by voice.

[0063] A reset circuit 15, which is electrically connected to the control unit 12 and is used for generating a reset signal and sending it to the control unit 12;

[0064] A control unit 12, which is used for generating a status reset signal for resetting the working state of the status indication circuit 14 according to the reset signal and sending it to the status indication circuit 14.

[0065] In this embodiment, the reset circuit 15 can generate a reset signal by setting a button or an externally input reset trigger signal. By pressing the button or receiving the reset trigger signal, the reset signal is generated to control the external controller B to reset the prompting state of the status prompting circuit 14.

[0066] In the present utility model, the wired anti-theft mouse is provided with a USB interface. The wired anti-theft mouse includes: a first wireless communication circuit; a plug-out detection circuit, which is arranged in the USB interface and is electrically connected to the main controller.
