A rotating shaft is rotatably installed on the inner wall of the guide plate, and a rotating plate is fixedly installed on the surface of the rotating shaft. A baffle is fixedly installed on the surface of the rotating shaft, and a trapezoidal plate is slidably installed on the top of the guide plate. A limiting plate is fixedly installed on the surface of the trapezoidal plate. By taking out the battery inside the power exchange cabinet body and then putting the original battery in, the battery will move along the pulley toward the charging port during the placement process, and at the same time, the position of the battery will be corrected in conjunction with the guide plate to ensure that the battery is directly inserted into the charging port.

[0007] According to the above technical solution, a No. 1 spring is provided between the guide plate and the trapezoidal skateboard. When the trapezoidal skateboard is separated from the battery, the elastic force of the No. 1 spring itself will drive the trapezoidal skateboard to reset. A No. 1 torsion spring is provided between the guide plate and the rotating shaft. When the rotating plate is separated from the trapezoidal skateboard, the elastic force of the No. 1 torsion spring itself will drive the rotating shaft to reset. A No. 2 spring is provided between the guide plate and the trapezoidal plate. When the trapezoidal plate is separated from the baffle, the elastic force of the No. 2 spring itself will drive the trapezoidal plate to reset.

[0008] According to the above technical solution, the push plate is provided with a heat dissipation device for dissipating heat and a protection device for protecting the battery. The heat dissipation device includes a connecting frame, a pulley frame and a sliding ladder frame. When the battery is inserted, the push plate will be pushed to move in the direction close to the fire extinguishing device. The movement of the push plate in the direction close to the fire extinguishing device will drive the connecting frame to move in the direction close to the fire extinguishing device. The movement of the connecting frame in the direction close to the fire extinguishing device will drive the pulley frame to move in the direction close to the fire extinguishing device. The connecting frame is fixedly installed on the top of the push plate, the pulley frame is fixedly installed on the top of the connecting frame, and the sliding ladder frame is slidably installed on the surface of the fire extinguishing device.

The sealing plate is slidably installed on the inner wall of the power exchange cabinet body. When the sliding frame moves away from the charging port, the sliding rod moves away from the charging port. When the sliding rod moves away from the charging port, the sealing plate moves away from the charging port. When the sealing plate moves away from the charging port, the heat dissipation hole will be opened to allow heat to be dissipated during battery charging.

[0010] According to the above technical solution, a No. 3 spring is arranged between the sliding ladder frame and the fire extinguishing device. When the pulley frame is separated from the sliding ladder frame, the elastic force of the No. 3 spring itself will drive the sliding ladder frame to reset. A No. 4 spring is arranged between the power exchange cabinet body and the sliding frame. When the push plate is reset, the elastic force of the No. 4 spring itself will drive the sliding frame to reset.

[0011] According to the above technical solution, the protective device includes a fixed plate, a dust shield plate and a connecting plate. The sealing plate moves away from the battery, driving the fixed plate to move away from the battery. The movement of the fixed plate away from the battery will push the dust shield plate to move away from the battery. The fixed plate is fixedly installed on the surface of the sealing plate, and the dust shield is slidably installed on the surface of the fixed plate. A heat dissipation groove is provided on the surface of the battery exchange cabinet body, and the dust shield is slidably installed on the inner wall of the heat dissipation groove. The connecting plate is fixedly installed on the bottom of the sealing plate.

[0012] According to the above technical solution, a rotating rod is rotatably installed on the inner wall of the battery exchange cabinet body, a short plate is fixedly installed on the surface of the rotating rod, a fixed frame is fixedly installed on the surface of the rotating rod, and a roller is rotatably installed on the inner wall of the fixed frame.

[0013] According to the above technical solution, a No. 5 spring is arranged between the dust shield and the heat dissipation groove. When the sealing plate is reset, the elastic force of the No. 5 spring itself will drive the dust shield to reset. A No. 2 torsion spring is arranged between the power exchange cabinet body and the rotating rod. When the short plate is separated from the connecting plate, the elastic force of the No. 2 torsion spring itself will drive the rotating rod to reset.

[0014] The present invention provides a short-circuit protection component for a two-wheeled electric vehicle battery exchange cabinet. It has the following beneficial effects: (1) This invention removes the battery from the battery swap cabinet and then replaces the original battery. During the insertion process, the battery will move along the pulley toward the charging port. At the same time, the position of the battery is corrected with the help of the guide plate to ensure that the battery is directly inserted into the charging port. This prevents deviation between the battery interface and the charging port during the insertion process, which may damage the charging port during the insertion process and prevent it from being used normally. At the same time, the pulley can reduce the wear on the bottom of the battery.

[0015] (2) In this invention, the rotation of the rotating shaft drives the baffle to rotate, and the rotation of the baffle pushes the trapezoidal plate to move toward the charging port. The movement of the trapezoidal plate toward the charging port drives the limit plate to move toward the charging port. The battery is limited by the limit plate to prevent the user from lifting one end of the battery during battery removal, causing damage to the battery interface and the charging port due to the change in angle, resulting in the charging port being unable to be used normally and posing a safety hazard. During the battery removal process, the electric telescopic rod drives the push plate to push the battery outward to ensure that the charging port is not damaged, thereby increasing the service life of the equipment.

[0016] (3) This invention, by sliding the ladder frame upward, will release the seal on the fire extinguishing device. When thick smoke is detected during charging, the smoke sensor will activate the fire extinguishing device to extinguish the fire and prevent the device from burning, which poses a safety hazard. By moving the sealing plate away from the charging port, the heat dissipation holes will be opened to dissipate heat during the battery charging process, preventing the heat dissipation holes from being open for a long time when not charging, causing external moisture to enter the interior of the device, resulting in damage to the device due to moisture between the charging port and the battery interface, affecting the normal use of the device.

[0017] (4) This invention pushes the dust shield plate away from the battery through the fixed plate, which will slide along the inner wall of the heat dissipation slot. The dust shield plate moves away from the battery to push away the dust and impurities stuck inside the heat dissipation slot, preventing the impurities from blocking the heat dissipation slot, resulting in the heat inside the device not being able to be discharged normally. The heat accumulation causes the device to overload, affecting the normal use of the device. The roller contacts the two sides of the battery to limit the battery, preventing the internal battery from colliding back and forth with the battery swap cabinet body when the battery swap cabinet body is hit during charging, causing the battery to be squeezed and damaged, affecting the normal use of the battery.
