[0020] The fixing device includes a support block 6, a scissor jack 16 and a second motor 7. Two support blocks 6 are symmetrically provided at both ends of the base plate 1. The support block 6 is provided with a through slot 14 running through its upper end face and lower end face. A scissor jack 16 is provided in the through slot 14. A second motor 7 is provided on one side of the support block 6. The second motor 7 is electrically connected to an external controller. The output shaft of the second motor 7 passes through the support block 6 and is arranged in the through slot 14. A coaxial connecting shaft 15 is provided on the output shaft of the second motor 7. The end of the connecting shaft 15 is connected to the screw of the scissor jack 16. The screw of the scissor jack 16 is rotatably connected to the inner wall of the other end of the through slot 14. The rotating connecting shaft 15 drives the scissor jack 16 to open and close. After the scissor jack 16 is opened, the lower end passes through the through slot 14 and is supported on the ground.

[0021] The upper and lower ends of the scissor jack 16 are both provided with support plates 17, and the outer surfaces of the support plates 17 are provided with anti-skid layers. The scissor jack 16 increases the contact area with the ground through the support plates 17, thereby increasing stability. The anti-skid layers prevent displacement when the support plates 17 at the lower ends of the scissor jack 16 are fixed.

[0022] The two ends of the base plate 1 are provided with electric push rods 8, which are electrically connected to an external controller. The ends of each electric push rod 8 are provided with a fixed block 9, which is arranged in conjunction with the automobile tire. The fixed block 9 has an inwardly concave arc surface structure facing the automobile tire. The side of the fixed block 9 abuts against the side of the tire. The two electric push rods 8 on one side of the base plate 1 are extended, and the two electric push rods 8 on the other side of the base plate 1 are shortened, thereby driving the base plate 1 to slide laterally to one side.

[0023] A horizontally arranged supporting plate 20 is provided in the fixed frame 2, and the upper end of the scissors lift 19 is hinged to the bottom surface of the supporting plate 20. A support plate 11 arranged parallel to the supporting plate 20 is provided above the supporting plate 20, and each cleaning roller 3 is arranged above the support plate 11. After the scissors lift 19 is extended, the upper cleaning rollers 3 can be attached to the lower end surface of the power battery pack shell.

[0024] One end of the cleaning roller 3 is rotatably connected to the inner wall of one side of the fixed frame 2, and the other end of the cleaning roller 3 passes through the fixed frame 2 and is connected to the output shaft corresponding to the multi-axis gearbox 4. Bristles are distributed on the side of the cleaning roller 3.

[0025] A scraper 22 is distributed on the upper end surface of the support plate 11. The scraper 22 is arranged in cooperation with the cleaning roller 3. The lower end surface of the scraper 22 is connected to the upper end surface of the support plate 11, and the upper end surface of the scraper 22 is attached to the side of the cleaning roller 3. When the cleaning roller 3 rotates, the upper edge of the scraper 22 scrapes off the dirt attached to the side of the cleaning roller 3, thereby improving the cleaning effect.

[0026] The support plate 11 is provided with perforations 12, and a guide cavity 21 is provided between the support plate 11 and the carrying plate 20. Each perforation 12 is connected to the guide cavity 21. An exhaust pipe 13 is provided on the side of the fixed frame 2. One end of the exhaust pipe 13 is connected to the guide cavity 21, and the other end of the exhaust pipe 13 is connected to an external vacuum cleaner. When the vacuum cleaner is working, it sucks out the air in the guide cavity 21, forming a negative pressure at each perforation 12, sucking the scraped attachments, and preventing dust and other attachments from floating around.

[0027] The embodiment of the present invention relates to a surface attachment cleaning device for cleaning power batteries. When in use, the base plate 1 is pushed under the car so that the fixing frame 2 is at one end of the power battery pack. The electric push rods 8 on both sides of the base plate 1 are extended, and the fixing blocks 9 are pressed against the corresponding tire sides. After the scissor lift 19 is turned on and the scissor lift 19 is extended, the upper cleaning rollers 3 can be attached to the lower end surface of the power battery pack shell. The electric push rods 8, the fixing blocks 9 and the fixing device cooperate to increase the stability during work. Then the external vacuum cleaner is connected to the exhaust pipe 13, and the second motor 7 is started to drive the connecting shaft 15 to rotate. The rotating connecting shaft 15 drives the scissor jack 16 to open and close. After the scissor jack 16 is opened, the lower end passes through the through slot 14 and is supported on the ground. The scissor jack 16 increases the contact area with the ground through the support plate 17, thereby increasing stability, and the anti-slip layer avoids shearing. When the support plate 17 at the lower end of the scissor jack 16 is fixed, displacement occurs, and then the first motor 5 is turned on. The first motor 5 drives the cleaning rollers 3 to rotate through the multi-axis gearbox 4 to remove the attachments on the outside of the power battery pack. During the cleaning process, the vacuum cleaner sucks out the air in the guide chamber 21, and forms a negative pressure at each perforation 12 to attract the scraped attachments to prevent dust and other attachments from drifting around. While the cleaning roller 3 rotates, the scraper 22 scrapes the dirt attached to the side of the cleaning roller 3 to improve the cleaning effect. After cleaning an area, the scissor jacks 16 on both sides are closed to separate the lower support plate 17 from the ground, control the two electric push rods 8 on one side of the bottom plate 1 to extend, and the two electric push rods 8 on the other side of the bottom plate 1 to shorten, thereby driving the bottom plate 1 to slide horizontally to one side, making it convenient to complete the cleaning of the bottom of the battery pack.
