Problems solved by technology

Because the traditional load-bearing body is mainly made of thin steel plates, thin steel plates can be welded by spot welding, which is easy to mass-produce, and the weight of the body is small, the overall bending and torsional rigidity is large, the floor of the compartment is low, and the height of the vehicle is small, but it can bear the lateral Poor impact and rear impact capabilities

Embodiment Construction

[0035] Such as figure 1 As shown, the load-bearing vehicle body provided by the embodiment of the present invention includes a rear floor of the vehicle body and a reinforcing beam structure fixed on the lower surface of the rear floor. reinforced beam structure such as figure 2 As shown, the left longitudinal beam 1, the right longitudinal beam 2, the front beam 3, the upper beam 4 and the rear beam 5 are included. The left longitudinal beam 1 and the right longitudinal beam 2 extend longitudinally along the left and right frames of the rear floor panel of the vehicle body, and the upper end surfaces of the openings are closely attached to the lower plane of the rear floor panel. The front cross member 3 connects the left longitudinal member 1 and the right longitudinal member 2 at the front ends of the left longitudinal member 1 and the right longitudinal member 2 . The upper beam 4 connects the left longitudinal beam 1 and the right longitudinal beam 2 at the middle of t...

Abstract

The invention discloses a bearing vehicle body, comprising a vehicle body rear floor and a reinforced beam structure which is fixed on the lower surface of the rear floor; wherein, the reinforced beam structure comprises a left longitudinal beam, a right longitudinal beam, a front transverse beam and an upper transverse beam; the left longitudinal beam and the right longitudinal beam are longitudinally extended along the left frame and the right frame of the panel of the vehicle body rear floor; the front transverse beam is connected with the left longitudinal beam and the right longitudinal beam at the front ends of the left longitudinal beam and the right longitudinal beam; the upper transverse beam is connected with the left longitudinal beam and the right longitudinal beam at the middle part of the left longitudinal beam and the right longitudinal beam. In the bearing vehicle body of the invention, the two longitudinal beams and the two transverse beams form a frame-typed reinforced beam structure which is fixedly connected with the vehicle body rear floor, thus effectively improving the collision-bearing capability of the side and rear of the bearing vehicle body.

Description

technical field [0001] The invention relates to a bearing type vehicle body. Background technique [0002] In the prior art, the load-bearing vehicle body is mainly composed of thin steel plates, and the engine, suspension, etc. are directly installed on the vehicle body. Because the traditional load-bearing body is mainly made of thin steel plates, thin steel plates can be welded by spot welding, which is easy to mass-produce, and the weight of the body is small, the overall bending and torsional rigidity is large, the floor of the compartment is low, and the height of the vehicle is small, but it can bear the lateral Poor impact and rear impact capabilities. Contents of the invention [0003] The object of the present invention is to provide a load-bearing vehicle body, which can improve the ability to withstand collisions laterally and rearwardly. [0004] The technical solution of the present invention is: a load-bearing vehicle body, including a rear floor of the ve...
