The moving box 2 is arranged at the bottom of the lift 1, an opening is provided at the front side of the moving box 2, and two box doors 3 that open opposite to each other are movably connected at the opening at the front side of the moving box 2. A moving structure is arranged inside the moving box 2, and the moving structure comprises two screw rods 4, a motor 5, a first sprocket wheel 6, two second sprocket wheels 7, a chain 8, a moving plate 9 and a plurality of moving wheels 10. The two screw rods 4 are rotatably connected to the top and the bottom of the moving box 2 respectively, and the two screw rods 4 are one left and one right. The motor 5 is arranged at the bottom of the moving box 2, the first sprocket 6 is arranged at the driving end of the motor 5, the two second sprockets 7 are respectively arranged on the two screws 4, the chain 8 is movably connected with the first sprocket 6 and the two second sprockets 7, and the chain 8 is respectively meshed with the first sprocket 6 and the two sprockets, the moving plate 9 is respectively threadedly connected with the two screws 4, and a through hole is opened on the moving plate 9, the through hole of the moving plate 9 corresponds to the position of the motor 5, and a plurality of moving wheels 10 are arranged at the bottom of the moving plate 9, and the plurality of moving wheels 10 are all movably passed through the bottom of the moving box 2.

[0019] Specifically, two limit plates 11 are provided on the left and right sides of the moving box 2 . The two limit plates 11 are located below the two second sprocket wheels 7 . The limit plates 11 are used to limit the moving plate 9 .

[0020] Specifically, a rubber pad 12 is provided at the bottom of the moving box 2, and a plurality of moving wheels 10 are movable through the rubber pad 12, and the rubber pad 12 increases the stability of the contact between the moving box 2 and the ground.

[0021] Specifically, a plurality of support rods 13 are disposed between the top and the bottom of the moving box 2 . The provision of the support rods 13 increases the support stability of the moving box 2 .

[0022] Specifically, the screw rod 4 is connected to the moving box 2 via a bearing, the inner ring of the bearing is interference fit with the screw rod 4 , and the outer ring of the bearing is fixedly connected to the moving box 2 .

[0023] Specifically, two cameras 14 are arranged on the top of the mobile box 2, and the two cameras 14 are arranged one on the left and one on the right. The cameras 14 can automatically monitor the bottom of the car, and the images will be transmitted to an external display.

[0025] Working principle: When the car lift 1 needs to be moved, the first sprocket 6 is first driven to rotate by the motor 5. Since the chain 8 is meshed with the first sprocket 6 and the two second sprockets 7, the two second sprockets 7 and the two screws 4 will also rotate synchronously. Since the moving plate 9 is threadedly connected with the two screws 4, when the screws 4 rotate, the moving plate 9 will move up and down along the length direction of the screws 4. When the moving plate 9 descends, the multiple moving wheels 10 at the bottom thereof will pass through the opening at the bottom of the moving box 2 and contact the ground, thereby realizing the separation of the car lift 1 from the ground. At this time, the operator can push or drag the car lift 1 to move. The presence of the moving wheels 10 greatly reduces the friction during movement, making the moving process easier and more convenient. When the car lift 1 needs to be fixed for lifting operation, it is only necessary to reversely drive the first sprocket 6 through the motor 5 to make the moving plate 9 rise and the moving wheels 10 leave the ground. At this time, the car lift 1 can be stably placed on the ground for lifting operation.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
