Abstract

The invention relates to an automobile front end collision force transmission structure which comprises a front end frame, a cooling system radiator, a main longitudinal beam, a front tire tread, a main energy absorption box fixing support, an auxiliary energy absorption box, an auxiliary anti-collision cross beam, a main energy absorption box, a main anti-collision cross beam, a cross beam connecting plate, an auxiliary frame connecting support and a main longitudinal beam front end fixing support. The main energy absorption box, the main anti-collision cross beam, the auxiliary energy absorption box, the auxiliary anti-collision cross beam and the cross beam connecting plate can be connected to form a full-coverage first-stage collision energy absorption protection cage type structure; the front end frame, the cooling system radiator, the main longitudinal beam, the front tire tread, the main energy absorption box fixing support, the auxiliary frame connecting support and the main longitudinal beam front end fixing support can be connected to form a full-coverage secondary collision energy absorption protection cage type structure. According to the structure, the upper, middle and lower multi-path force transfer design realizes effective coverage of the MPDB working condition evaluation area force transfer structure and reasonable distribution of counterguard collision contact loads, thereby reducing MPDB working condition counterguard compatibility penalty scores and greatly improving the automobile collision compatibility protection capability.

Description

technical field [0001] The invention belongs to the technical field of vehicle collision, and in particular relates to an automobile front-end collision force transmission structure and a vehicle. Background technique [0002] At present, the traditional force transmission structure of the car body is mostly a single force transmission path based on the energy-absorbing box and the longitudinal beam. The collision load is concentrated and the cross-sectional force of the force transmission path is large, so as to meet the requirements of frontal collision and offset collision for collision safety performance. . However, in the actual collision process, if the car body is too weak or too strong, one party in the accident will suffer more serious damage. In order to solve the reasonable matching of car body strength, collision compatibility regulations have emerged as the times require. Therefore, the design idea and matching method of the force transmission path structure at...
