Abstract

The invention relates to a multi-gear pneumatic limiting structure of an automobile. The multi-gear pneumatic limiting structure of the automobile comprises a shaft rod, a first leaf, an elastic bracket, an elasticity output assembly, a limiting plate, a second leaf and a fastening nut, wherein the shaft rod sequentially passes through a first leaf running hole, an elastic bracket running hole, a limiting plate running hole and a second leaf running hole and then is connected through the fastening nut and outer threads. According to the scheme, the multi-gear pneumatic limiting structure of the automobile has the advantages that a force is generated according to the relation between the pressure of air in a piston cylinder and the plane, namely, the force F=P*delta S for limiting is generated through the area difference delta S between the upper surface and the lower surface of a resisting rod; the structure can be utilized when a common elastic part cannot supply elasticity as requirement; the pressure of the air in the cylinder can be changed to supply the working force, and thus the functionality problem can be solved.

Description

technical field [0001] The invention belongs to the technical field of car bodies, in particular to an automobile multi-gear air pressure limiting structure for opening and closing a vehicle door. Background technique [0002] In the prior art, the car door stopper generally adopts an independent structure, which is divided into two parts for installation: one part is installed on the car door, and the other part is installed on the car body corresponding to the car door. [0003] The car door limiter structure of prior art is roughly as figure 1 As shown, it includes connection bracket 01, connection bracket rivet 02, arm rod 03, dust pad 04, installation cover 05, spring or other elastic body 06, ball seat 07, steel ball 08, pressure plate 09, buffer pad 010; installation screws 011 and shell 012. [0004] Wherein, the connecting bracket is mainly installed and fixed on the side sheet metal of the vehicle body, and the housing is installed on the door sheet metal through...
