Fixing support of mechanical jack of automobile and fixing method of jack

Abstract

The invention relates to a fixing support of a mechanical jack of an automobile. The fixing support of the mechanical jack of the automobile is characterized by comprising a tension brace (21), a first supporting body (28) and a second supporting body (29), wherein the first supporting body (28) and the second supporting body (29) are symmetrically arranged at two ends of the tension brace (21). Limiting baffles (23) are respectively symmetrically arranged on the front sides and the rear sides of both a first supporting body supporting surface (22) of the first supporting body (28) and a second supporting body supporting surface (26) of the second supporting body (29). The fixing support of the jack further comprises a limiting rod and an adjusting device, one end of the limiting rod is fixed with a rear side vertical plate (27) of the tension brace (21) after penetrating through a jack recession (14), and the other end of the limiting rod and the adjusting device are matched with each other to jointly abut against the jack in a Z direction so as to perform fixing. The fixing support of the mechanical jack of the automobile is simple in structure and low in cost, enables the jack to be free of vibration during the vehicle driving process, reduces damage to other parts of an automobile body caused by the jack, and can reduce noise in the automobile.

Description

technical field [0001] The invention belongs to the design field of on-board accessories for automobiles, in particular to a fixing bracket of an automobile mechanical jack and a fixing method for the jack. Background technique [0002] At present, the methods of fixing automobile mechanical jacks can be roughly divided into four types. The advantages and disadvantages of each fixing method are analyzed as follows: [0003] Method 1: Put the car jack directly in the hub of the spare tire, but the fixing method does not fasten the car jack to the body, which will easily cause vibration with the bumps of the car during driving and increase the noise inside the car. [0004] Method 2: Use cable ties to fix the car jack on the carpet or the interior guard plate. Although the fixing method fixes the car jack on the vehicle body, the strength of the cable tie, carpet and guard plate is not high. In bad road conditions, severe vibrations can easily damage cable ties, carpets or gu...

Problems solved by technology

Although its fixing method avoids the defects of methods 1 and 2, and the on-board tools are easy to install and remove, it needs to form a groove similar to the shape of a jack on the underbody of the vehicle body, requiring a large space in the car, and it will be more difficult to stamp and form. Generally, the space in the miniature car is limited, so it is difficult to adopt this kind of fixing method.

[0006] Method 4: Another device for installing jack equipment is welded on the vehicle body floor, and the car jack is fixed on the device. Although the fixing method avoids the defects of the first three methods, the structural design of the device cannot prevent rotation, and When the car body is driving on a bumpy road, the severe vibration will cause the jack to loosen and fall off, which will not only increase the noise in the car, but also the severe contact vibration between the car jack and the bottom plate will make the bottom plate very easy to damage
