Abstract

The utility model is in request for protection of a car central pillar hinge installation enhanced piece, which is a single part and T-shaped in a whole, with the side presenting an arc the same as the central pillar and covering the whole central pillar. The two side edges of the utility model are shaped into flanging in welding connection with the central pillar enhanced piece; the top edge of the T-shaped part is shaped into flanging in welding connection with a coping; a hinge installation hole is arranged on the middle and lower parts of the utility model; a retainer installation hole and a lockpin through-hole are arranged on both sides of the utility model. With the integration of the original central pillar enhanced piece and all enhanced pieces among the coatings inside the central pillar into a single part of the utility model, the stiffness of the central pillar hinge and the retainer and the intension of the joint between the upper central pillar and the side beam of the coping can be improved. The tension of the whole central pillar is improved to avoid cracking resulting from the centralized stress.

Description

A kind of automobile central post hinge is installed reinforcement

Technical field

The utility model relates to automotive body structure.

Background technology

The central post bulk strength of auto body influences the side face collision safety performance of car load, and parts installation position rigidity such as its hinge also can cause car door sagging inadequately, have destroyed door sealing, cause the opening/closing door of vehicle difficulty.In order to address this problem, adopting usually during automobile design at present increases multi-form reinforcement between the two at central post reinforcement and central post inside panel, as body hinge reinforcement, limiting device reinforcement etc., increases local stiffness.But required like this part is more, complexity is installed, and can not effectively guarantees bulk strength.

Summary of the invention

The purpose of this utility model is the problem at the prior art existence, proposes a kind of automobile central post hinge reinforcement is installed, and by body hinge reinforcement, limiting device reinforcement etc. is integrated into a part, increases the bulk strength of central post.

The technical solution of the utility model is as follows:

A kind of automobile central post hinge is installed reinforcement, is a single-piece single component, and its integral body is T-shaped, and side direction is the arc consistent with central post, and the position covers whole central post.There is the flange with the welding of central post reinforcement its both sides, flange with the top cover welding is arranged at T shape top, make the central post hinge that "T"-shaped top and the central post reinforcement and the top cover weld together of reinforcement are installed like this, to strengthen the Joint strenght of central post top and top cover curb girder.The middle and lower part that the central post hinge is installed reinforcement is furnished with hinge mounting hole, both sides are furnished with limiting device mounting hole and lock pin via hole, T shape top also has two rectangular heavy stand holes that are used for by welding gun, like this body hinge, limiting device, Qianmen lock pin box all are installed in the central post hinge and install on the reinforcement, realize that single component is multi-functional.

The utility model by will be in the past various reinforcements between central post reinforcement and the central post inside panel be integrated into a single component, improve the hinge of central post and the rigidity of limiting device installation position, strengthen the connecting portion intensity of central post upper end and top cover curb girder again, prevent owing to stress concentration ftractures, improve the central post bulk strength.
