A hatchback vehicle rear door lock post rubber tough base and its construction method

Abstract

The invention relates to a rubber toughness base of a lock pillar of a back door of a hatchback vehicle and a construction method thereof. A structure of a rubber fixed mount is designed according to matching positions of a back door lock and the lock pillar, so that the structure of the rubber fixed mount is matched with a vehicle body structure and arrangement space; the lock pillar is vulcanized and fixed in a rubber body; the fixed mount is connected with the rubber body in a vulcanizing manner to form a novel lock pillar toughness base; and the toughness base is fixed on a vehicle body by a bolt to finish a use function of the rubber toughness base, so that the thinking that the structural damage position is simply reinforced is broken, and a rigid fixing structure of the lock pillar base of the back door of a traditional hatchback vehicle is replaced by the rubber deformable toughness base.

Description

technical field [0001] The invention relates to a rubber flexible base of a rear door lock column of a hatchback type vehicle and a construction method thereof. Background technique [0002] For the design of the rear door lock cylinder of a hatchback vehicle, the design company generally adopts a metal fixed rigid structure, and the function of locking the rear door can be realized through the cooperation of the lock hook and the lock cylinder. [0003] During the operation of the vehicle, a certain amount of relative deformation needs to occur between the various parts of the vehicle to release energy and balance the changes in various postures of the vehicle body. For the subsystem composed of the rear frame of the vehicle body, the back door, the hinge and the door lock, since the structures of each part are rigidly designed and connected, it is difficult to coordinate and release the deformation and energy generated during the movement of the vehicle. It often leads to...
