Problems solved by technology

In this structure, there is no effective transverse connection between the longitudinal components. During a collision, especially when the vehicle collides on the left or right side, there are discontinuous collision force transmission channels, excessive acceleration of the vehicle body, and excessive deformation of the passenger compartment. and other problems, it is easy to cause greater injury to the occupants

Embodiment Construction

[0023] see figure 1 , is an embodiment of the automobile body frame structure of the present invention.

[0024] The frame structure of the automobile body in this embodiment includes a frame of the front cabin and a frame of the passenger compartment.

[0025] The front cabin framework includes a front anti-collision beam 1 , an energy absorbing box 2 , a front cabin longitudinal beam 3 and a front cabin upper short beam 4 . The root of the longitudinal beam 3 of the front cabin is connected with the lower cross member 7 of the dash panel. The upper short beam 4 of the front cabin is located above the longitudinal beam 3 of the front cabin, and is connected with the upper end 8 of the A-pillar and the lower beam 5 of the front windshield. The front anti-collision beam 1 is arranged at the front end of the vehicle body and is connected with the energy-absorbing box 2, and the energy-absorbing box 2 is installed on the longitudinal beam 3 of the front cabin through several bo...

Abstract

The invention provides an autobody framework structure which comprises a passenger compartment framework. The passenger compartment framework comprises a front wall framework and a floor framework, wherein the front wall framework comprises bodywork columns A, the floor framework comprises threshold beams, the bottoms of the bodywork columns A are connected with the front ends of the threshold beams, the front wall framework further comprises front wall plate beams, and the two ends of the front wall plate beams are connected together with the bodywork columns A. The front wall plate beams are arranged between the bodywork columns A of the autobody framework structure and the two ends of the front wall plate beams are connected together with the bodywork columns A, so that a whole collision force transmission channel is formed, the accelerated speed of a bodywork and deformation of a passenger compartment can be reduced and passengers are prevented from being seriously damaged in collision.

Description

technical field [0001] The invention relates to an automobile body structure, in particular to an automobile body skeleton structure capable of reducing the acceleration of the vehicle body and the deformation of the passenger cabin during a collision. Background technique [0002] As consumers pay more and more attention to automobile safety and the requirements of collision safety regulations continue to improve, automobile manufacturers put forward higher and higher requirements for automobile safety design. As the main load-bearing structure of automobile collision, the body should have the function of absorbing collision energy and dissipating collision force through reasonable deformation, so as to reduce the occupant's injury. Therefore, whether the body structure design is reasonable or not has become an important factor affecting the safety of automobile collisions. In the current common body structure, the longitudinal body consists of an energy-absorbing box, a f...
