[0036] A driving device is connected to the opening and closing device.

[0037] In this embodiment, the mouse guard 2 is connected to one of the door frames 3 via at least one hinge 10. Figure 5 As shown, the mouse guard 2 is connected to the door frame 3 through two hinges 10, and the mouse guard 2 can be closed or opened by setting the door frame 3; the mouse guard 2 is preferably made of stainless steel or aluminum alloy, which can improve the adaptability and durability of the device and extend its service life.

[0038] The opening and closing device comprises a first pull rod 6, a second pull rod 5 and a connecting seat 4, wherein one end of the first pull rod 6 is hingedly connected to the driving device and the other end is hingedly connected to the second pull rod 5, and the second pull rod 5 is fixedly connected to the connecting seat 4 provided on the mouse guard 2. Figure 1 or Figure 2 As shown, the opening and closing device of the device utilizes the motor 7 to drive the first pull rod 6 to move, and the first pull rod 6 thereby drives the second pull rod 5 to open or close the mouse guard door, ensuring that the mouse guard plate 2 can be opened and closed quickly and accurately.

[0039] The driving device includes a motor 7 and a control unit for controlling the movement of the motor 7. The control unit includes a microcontroller MCU and a communication interface module, an input interface module, a security protection module, a clock module, a power management module, an output drive module, a user interface module, a sensor interface module and a fault diagnosis module respectively connected to the microcontroller MCU. The power management module includes a power supply module for providing power to the motor 7 and the control unit; the output drive module includes a relay for driving the motor 7; the input interface module includes a wired interface, a Bluetooth module and a WIFI module.

[0040] like Figure 3 The figure shows a schematic diagram of a control unit. In this embodiment, the microcontroller (MCU) is the core of the control unit, which is responsible for executing program codes, processing input signals, and outputting control signals to the motor 7. The power management module includes a power converter and a power supply module to provide a stable power supply for the control unit and the motor 7. The input interface module is used to receive external signals, which can be a switch button, a sensor, a wireless communication module (Bluetooth, Wi-Fi, ZigBee, etc.), or a wired interface (such as RS-232, RS-485, Ethernet, etc.), and different methods are selected according to different situations. The output drive module of this embodiment converts the control signal of the microcontroller into a signal suitable for driving the motor 7. The communication interface module includes serial communication or wireless communication; the sensor interface module includes a speed sensor for monitoring the opening or closing of the mouse guard 2 and a position sensor for monitoring the position of the mouse guard 2.

The sensor interface module is used to connect the position sensor and the speed sensor, and is used to monitor the position of the mouse guard 2 in real time. The safety protection module is used to ensure that the motor 7 and the control unit will not be damaged under abnormal conditions. The user interface module is an LED indicator light, so that the operator can monitor the status of the motor 7 and debug in real time. The clock module is used for time-related control logic, such as delayed shutdown. The fault diagnosis module is used to detect and record system faults, which may include self-check programs and fault code generation.

[0042] The control unit of this device can receive control signals, such as door opening signals or door closing signals, and perform corresponding actions according to the requirements of the signals. The motor 7 can adjust the speed of the motor 7 as needed to achieve slow opening or fast opening of the mouse guard 2, or slow closing or fast closing.

[0044] In this embodiment, the mouse guard strip 8 is preferably made of a PVC soft and hard composite material. The mouse guard strip 8 uses this material to make comprehensive use of the softness and hardness characteristics of the PVC material. Figure 4 As shown, the protruding part at the bottom of the mouse guard strip 8 is made of a soft material. The soft material can provide a certain amount of elasticity and flexibility, so that the mouse guard strip 8 can better adapt to the uneven ground during the rotation of the mouse guard 2; the rest of the mouse guard strip 8 is made of a hard material, which can provide sufficient strength and stability to prevent small animals such as mice from entering.

[0045] Working principle: The control unit set in this device uses the input interface module to receive external signals. After receiving the signals, the microcontroller (MCU) will verify, convert and decode the signals, and send instructions to the motor 7 according to the received control signals (such as opening or closing the door). After receiving the instructions, the motor 7 will adjust its speed and rotation direction, and transmit the power to the mouse guard 2 through the first pull rod 6 and the second pull rod 5 to realize the automatic opening or closing of the mouse guard 2.
