A multi-gear air pressure limit structure for automobiles

Abstract

The invention relates to a car multi-switching pneumatic limiting structure. The car multi-switching pneumatic limiting structure comprises a shaft rod, a first fan blade, an elastic support, an elastic output assembly, a limiting disc, a second fan blade and a fastening nut, wherein the shaft rod sequentially penetrates through a first fan blade via hole, an elastic support via hole, a limiting disc via hole and a second fan blade via blade, and then is in threaded connection with an outer thread of the shaft rod through the fastening nut. According to the technical scheme, modular assembling of a limiting mechanism and a hinge or a hinge mechanism is realized, the requirements for the surroundings by an independent limiting mechanism are reduced, and the overall car space design is optimized. For example, when the limiting mechanism is arranged in a car door inner cavity, the moving space of lifting glass and the relevant guide rail length in the door inner cavity are occupied, and then glass lifting formation and stability are affected. When the limiting mechanism is arranged in a car body, an independent cavity needs to be designed for the limiting mechanism, and the number of metal plates and the number of relevant work procedures are increased.

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, including connecting bracket 01, connecting bracket rivet 02, arm rod 03, dust pad 04, mounting cover 05, spring or other elastic body 06, ball seat 07, steel ball 08, pressure plate 09, buffer pad 010, mounting screw 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 mounting s...
