[0044] The lifting assembly 100 also includes an identification assembly, at least a portion of which is disposed on the supporting assembly 10. The identification assembly is configured to identify the position of the tire to be lifted in a preset horizontal direction and the diameter of the tire to be lifted, and to adjust the position of the supporting portion 11 along the preset horizontal direction based on the identification result of the identification assembly. The identification result of the identification assembly includes the position of the tire to be lifted in the preset horizontal direction and the diameter of the tire to be lifted, as identified by the identification assembly. By providing the identification assembly, the position of the tire to be lifted in the preset horizontal direction and the diameter of the tire to be lifted can be automatically identified.

[0045] Since at least a portion of the identification component is disposed on the supporting component 10 , when the supporting component 10 moves in the vertical direction, the portion of the identification component disposed on the supporting component 10 is driven to move in the vertical direction together.

[0046] Specifically, for the case where one of the supporting parts 11 of the supporting assembly 10 is movably arranged along a preset horizontal direction and the other supporting part 11 is immovable along the preset horizontal direction, the two supporting parts 11 of the supporting assembly 10 are respectively a first supporting part 1101 and a second supporting part 1102, the first supporting part 1101 is movably arranged along the preset horizontal direction, and the second supporting part 1102 is immovable along the preset horizontal direction; first, the tire to be lifted is moved to a suitable position in the preset direction, such as Figure 8 As shown, the tire to be lifted is located near one side of the supporting assembly 10 in the first horizontal direction, and the first horizontal direction is perpendicular to the preset horizontal direction. Then, the supporting assembly 10 is moved along the first horizontal direction and toward the direction close to the tire to be lifted, so that the two supporting parts 11 are arranged corresponding to the tire to be lifted in the first horizontal direction, as shown in FIG. Figure 9 As shown, at this time, the two supporting parts 11 and the tire to be lifted are distributed along the preset horizontal direction, and the two supporting parts 11 are located on both sides of the tire to be lifted; then the vehicle to be lifted is moved along the preset horizontal direction so that the second supporting part 1102 is located below the tire to be lifted, as shown in FIG.

[0047] Specifically, in the case where both supporting parts 11 of the supporting assembly 10 are movably arranged along a preset horizontal direction, the tire to be lifted is first moved to a suitable position in the preset direction, such as Figure 8 As shown, at this time, the tire to be lifted is located near one side of the supporting assembly 10 in the first horizontal direction, and then the supporting assembly 10 is moved along the first horizontal direction and toward the direction close to the tire to be lifted, so that the two supporting parts 11 are arranged corresponding to the tire to be lifted in the first horizontal direction, as shown in FIG. Figure 9 As shown, at this time, the two supporting parts 11 and the tire to be lifted are distributed along the preset horizontal direction, and the two supporting parts 11 are located on both sides of the tire to be lifted; then the two supporting parts 11 are moved along the preset horizontal direction so that the two supporting parts 11 are located below the tire to be lifted, as shown in FIG.

[0092] Specifically, the display 50 is also used to display the lifting height information of the tire during the lifting process.

[0093] In the present application, a sensing component is provided at a preset position of the supporting portion 11, so that when the sensing component senses the tire, the supporting portion 11 supports the tire and stops moving along the preset horizontal direction.

[0094] Specifically, the supporting portion 11 moves in a preset horizontal direction, gradually moving below the tire. When the supporting portion 11 is able to stably support the tire, the sensing component senses the tire, causing the supporting portion 11 to stop moving in the preset horizontal direction.

When the movable member 22 moves in the vertical direction, the two guide members 40 of the guide pair group slide along the preset portions on the first inner wall 212 and the second inner wall 213. In this way, the two guide members 40 of the guide pair group cooperate with the preset portions on the first inner wall 212 and the preset portions on the second inner wall 213, respectively, to guide the movement of the movable member 22 in the vertical direction. Furthermore, since the first inner side wall 212 and the second inner side wall 213 are arranged relative to each other, and the two guide members 40 of the guide pair group are respectively abutted against the preset portions on the first inner side wall 212 and the preset portions on the second inner side wall 213, the stability of the movable member 22 in the installation space 211 can be ensured in the distribution direction of the first inner side wall 212 and the second inner side wall 213, thereby ensuring the stability of the lifting of the lifting equipment.

[0100] The sliding engagement of the guide member 40 with the pre-set portion reduces wear on the lifting device during lifting, thereby increasing the service life of the lifting device.
