Abstract

The invention relates to a single-board structural internal truss car body and belongs to the technical field of cars. The single-board structural internal truss car body comprises a plurality of inner support beams. Side single-board coverings, a top single-board covering and a rear single-board covering are connected to the inner support beams. Bottom boards are disposed at the bottoms of the inner support beams. The side single-board coverings, the top single-board covering, the rear single-board covering and the bottom boards are welded to form a car body frame structure. A first cavity forms among welded parts of the side single-board coverings and the top single-board covering. A second cavity forms among the side single-board coverings and the bottom boards. The single-board structural internal truss car body has the advantages that the outer coverings and the inner support beams in the single-board structural car body can share the load of a car, fewer inner support / reinforcing truss structures of the car body need to be independently produced, fewer parts are required, and the weight of the car body is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an endogenous truss car body with a single-layer plate structure. Background technique [0002] Most of the existing single-layer plate structure automobile body is to make the inner supporting / strengthening truss structure of the car body first, and then lay the outer single-layer plate skin on the truss structure. In this kind of car body structure, the truss structure inside the car body bears most of the load, and the outer single-layer skin only forms the outer cover of the car body, and the load it bears is very small, and there are many parts. more cumbersome. Contents of the invention [0003] The object of the present invention is to provide an endogenous truss vehicle body with a single-layer plate structure aiming at the defects of the prior art. [0004] The technical solution adopted in the present invention is: an endogenous truss car body with a...
