[0014] The utility model is described in detail below in conjunction with specific implementation methods:

[0015] like Figures 1 to 3 The plug-in and unplugging device shown is compatible with multiple types of plugs, including an XY-axis displacement mechanism 1, a crossbeam 2, a motor seat 3, a drive motor 4, a rack 5, a grabbing mechanism, an electric push rod 7 and a rotating shaft. The rear end of the crossbeam 2 is fixedly mounted on the Y-axis slider of the XY-axis displacement mechanism 1, and the rotating shaft is rotatably mounted on the front end of the crossbeam 2. The main body of the electric push rod 7 is hingedly mounted on the crossbeam 2. A push plate is fixedly sleeved on the rotating shaft, and a long hole is provided on the push plate. The electric push rod 7 and the actuator rod are slidably mounted in the long hole of the push plate. The motor seat 3 is fixedly mounted on the lower end of the rotating shaft, the drive motor 4 is fixedly mounted on the motor seat 3, and a gear is fixedly sleeved on the output shaft of the drive motor 4. A guide sleeve is fixedly mounted on the motor seat 3, and the rack 5 is slidably mounted in the guide sleeve. The rack 5 is meshed and transmission-connected with the gear, and the grabbing mechanism 6 is fixedly mounted on the bottom end of the rack 5.

[0016] The grabbing mechanism is composed of a bearing seat and an electromagnet 8, the bearing seat is fixedly mounted on the bottom end of the rack 5, the electromagnet is fixedly mounted on the bearing seat, the bearing seat is fixedly connected by an upper connecting plate 61, a lower connecting plate 62 and a connecting rod 63, the upper and lower ends of the connecting rod 63 are set as reverse thread structures, the upper and lower ends of the connecting rod 63 are respectively screwed and fixed to the upper connecting plate 61 and the lower connecting plate 62, a containing area is formed between the upper connecting plate 61 and the lower connecting plate 62, the electromagnet 8 is located in the containing area, it is convenient for maintenance and replacement of the electromagnet 8, and it is beneficial to the heat dissipation of the electromagnet, which can extend its service life, and the electromagnet 8 is fixedly mounted on the lower connecting plate 62, and the upper connecting plate 61 is fixedly mounted on the bottom end of the rack 5.

[0017] It includes a position laser sensor 9 and a control module. The position laser sensor 9 is fixedly installed on the crossbeam 2. The motor seat 3 is fixedly installed with a position laser point end plate 91. The position laser sensor 9 and the drive motor 4 are respectively connected to the control module by circuits. The laser point end plate 91 sends a laser to the laser point end plate 91 for ranging, and then transmits the data to the control module. The control module controls the start and stop of the drive motor 4.

[0018] The charging plug 10 is placed on the tray 101, and the XY axis displacement mechanism 1 controls the crossbeam 2 to move in the XY axis direction, and the driving motor 4 is started to drive the gear to rotate, and the gear drives the rack 5 to move up and down, thereby driving the grabbing mechanism at the bottom of the rack to move up and down.

The charging plug 10 can be pulled out of the battery charging port by the suction force of the electromagnet 8. Due to the size of the battery tray, the charging plug 10 is a non-square structure. When the charging plug 10 is placed at one end of the battery tray, the direction is set 90° perpendicular to the direction of the battery charging port. Therefore, it is necessary to use the actuator rod of the electric push rod 7 to drive the rotating shaft and the motor seat 3 to rotate 90° to meet the actual use requirements.
