Description

Technical Field

[0001] The utility model relates to the technical field of vehicle maintenance, in particular to a vehicle lifting arm. Background Art

[0002] For new energy vehicles, the battery pack is one of its important components. When the battery pack is installed at the designated position of the vehicle, most of the existing technologies use a lift to lift the vehicle to a certain height. However, the lifting arms of current lifts are too long to reserve support positions for the lift on both sides of the larger battery pack. Therefore, in order to accommodate larger battery packs, existing lifts will replace the long rear lifting arms with short lifting arms. However, using short lifting arms for both the front and rear lifting arms will cause uneven front and rear weight distribution after the vehicle with a forward center of gravity is lifted, resulting in instability and potential safety hazards.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] like Figure 1 As shown, in one embodiment, a vehicle lifting arm can adjust the center of gravity of the lifted vehicle by setting the short telescopic arm 3 for support in the lifting arm at a connection position away from the lift column 1, so as to maintain the stability of the lifted vehicle and reduce the existence of safety hazards.

[0024] The specific structure of the vehicle lifting arm includes:

[0025] Column 1, specifically the installation location of the lift column 1;

[0026] A support platform 2 is fixed on the upper end of the column 1. The support platform 2 is a square structure, wherein the column 1 is fixed on one end of the support platform 2, and a short telescopic arm 3 is rotatably hinged on the other end of the support platform 2.

[0027] Through the above technical solution, since there is a distance of the entire length of the support platform 2 between the installation position of the lift column 1 and the short telescopic arm 3, the lift can adjust the center of the lifted vehicle when lifting the vehicle, thereby improving the stability of the lifting. Specifically, when the existing vehicle is lifted, the distance between the front short lifting arm and the rear long lifting arm can be 150cm. When the center of gravity of the vehicle is forward, the distance between the front and rear lifting arms is short, resulting in an unstable center of gravity of the vehicle. However, in the present application, since a support platform 2 with a certain length is added between the lift column 1 and the short lifting arm, the distance between the front short lifting arm and the rear long lifting arm is increased, so that the vehicle can be more stable when being lifted.

[0028] The specific structure of the short telescopic arm 3 includes a large arm and a supporting small arm sleeved inside the large arm. The short telescopic arm 3 is driven by hydraulic pressure. The short telescopic arm 3 is hinged to the supporting platform 2, so that the short telescopic arm 3 can adjust the angle and improve the applicability of the lifting arm.

[0029] Furthermore, the support platform 2, the short telescopic arm 3 and the reinforcing arm 4 form a triangular structure, so that the stability of the short telescopic arm 3 can be enhanced, especially after the short telescopic arm 3 is adjusted to a certain angle, the stability of the short telescopic arm 3 can be enhanced by the reinforcing arm 4.

[0030] Among them, the structure of the short telescopic arm 3 is a telescopic hydraulic rod, which is hinged to the short telescopic arm 3 and one end of the support platform 2, and the angle of the short telescopic arm 3 can be adjusted by the telescopic hydraulic rod.

[0031] Please refer to Figure 2 In some preferred embodiments, a plurality of reinforcing ribs 5 are provided inside the supporting arm of the short telescopic arm 3 along its axial direction, thereby improving the strength of the short telescopic arm 3 and being able to withstand vehicles of greater weight.

[0032] Please refer to Figure 3 In some preferred embodiments, a threaded hole is provided at the top of the support arm, and a support end 6 is threadedly connected to the threaded hole. The support end 6 is a prism structure, and the support height can be increased by rotating the support end 6. Furthermore, a silicone layer is provided at the top of the support end 6 to reduce damage to the vehicle or battery pack when the support end 6 is supporting.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
