Description

Buttress brace under front floor

Technical field

This utility model belongs to vehicle accessory field, buttress brace under especially a kind of front floor.

Background technology

The Main Function of automotive floor panel crossbeam is to support and stress, so crossbeam needs enough rigidity and intensity to protect The torsion of card vehicle body and mode, current rear floor crossmember is configured without rational reinforcing plate.

Widely available with automobile, automobile especially car has become as the important component part of the modern life, and it is straight Connect the impression affecting us and life.Meanwhile, with people, the understanding of automobile is constantly deepened, they are to selection automobile Require also can more and more higher, automotive performance selected one of important indicator of automobile as client.And body performance is in automobile Embody in performance that its powerful status is more and more obvious, the rigidity of vehicle body, mode directly affects relaxing of interior of body occupant Adaptive, is to determine one of precondition of comfortableness of occupant；The factor of the collision safety emphasis examination of automobile is vehicle body Whether rigidity, structure design, welding performance have reached requirement, and outstanding car load passive security performance protects in-car one-tenth well Member.Complete vehicle weight is the key index determining car load dynamic economicses and chassis braking, handling stability energy again.

According to retrieval, find patent documentation related to the application as follows, specific disclosure is as follows：
