Abstract

The invention relates to a car component, in particular to an integral car body frame. The integral car body frame comprises an integral side wall frame and a lower car body intermediate frame at the bottom of the integral side wall frame, and the integral side wall frame comprises an integral side wall frame outer board and an integral side wall frame inner board which are formed via full-length welding by a laser. The integral car body frame has the advantages that parts are reduced, costs on dies, clamps and test tools in a developing process are reduced, and lightening of an integral car and oil consumption reduction are benefited.

Description

Technical field [0001] The invention relates to an automobile component, in particular to an integral body frame. Background technique [0002] The traditional car body is tailor-welded by many thin-plate stamping and forming parts. The welding process is complicated. Too many parts lead to accumulated errors in assembly accuracy, and spot welding easily deforms the parts. Summary of the invention [0003] The purpose of the present invention is to provide an integral body frame, which reduces the number of parts, and has good strength and rigidity in view of the shortcomings of the prior art. [0004] The technical solution of the present invention is an integral body frame, which is composed of an integral side frame and a lower car body frame at the bottom of the integral side frame, and the integral side frame includes an integral side frame outer panel And the integral side frame inner plate, and the integral side frame outer plate and the integral side frame inner plate are a...
