A kind of car jack and lifting method thereof

Abstract

The invention provides an automobile jack. The automobile jack comprises a jack body (10) and a detachable jack head (20); the top of the jack body (10) is provided with a fixed jack head (14); the detachable jack head (20) is arranged on the fixed jack head (14) detachably. The automobile jack has higher universality, so that jacks with different height limits and different jack head structures can be realized, and the requirements of different vehicles on the lifting height are met; meanwhile, due to the addition of detachable jack heads with different specifications, the structural size of the jack body is reduced, so a storage space that the whole jack occupies becomes smaller, and the deployment space of the whole vehicle is greatly reduced. The jack has a simple integral structure, is convenient to operate and is low in manufacturing cost, the standardized and universal production and sale of the jack can be realized through a series of jack head heights and structures, and the automobile jack has broad market prospect.

Description

technical field [0001] The patent of the present invention relates to the technical field of on-board tools for automobiles, in particular to an automobile jack with a variable maximum lifting height and a lifting method thereof. Background technique [0002] Due to the inconsistencies in the parameters such as the suspension downstroke, tire deformation, and the height of the jack support point on the car body of different vehicles, when the car owner disassembles the wheel by himself, the maximum lifting height required by different vehicles is not uniform, which eventually leads to the development of automobile OEMs. The generalization degree of the jack is low, and it brings waste phenomenon of repetitive development. There are also some vehicles (especially SUV models) that require bulky high-travel jacks to meet their lifting requirements, and it is often difficult to arrange such bulky jacks in the limited trunk space. In addition, due to the differences in the suppo...

AI Technical Summary

Problems solved by technology

[0002] Due to the inconsistency of the parameters such as the suspension downstroke, tire deformation, and the height of the jack support point on the car body of different vehicles, when the owner disassembles the wheel by himself, the maximum lifting height required by different vehicles is not uniform, which eventually leads to the development of automobile OEMs. The generalization degree of the jack is low, and it brings waste of repetitive development

There are also some vehicles (especially SUV models) that require a bulky high-travel jack to meet their lifting requirements, and it is often difficult to arrange such a bulky jack in the limited trunk space

In addition, due to the difference in the support point structure of the jack on the car body, it is also necessary to design a jack with a different jack structure to match the car body with different support point structures, otherwise, the contact effect of the jack head is not good, and even brings safety problems

Therefore, the existing automobile jacks generally have problems such as fixed maximum lifting height and poor universality of different vehicles.
