Automobile little offset collision force transmission mechanism and automobile including same

Abstract

The invention provides an automobile little offset collision force transmission mechanism and an automobile including same. The automobile little offset collision force transmission mechanism comprises a sub frame mounting seat, a sub frame, a front longitudinal beam, a wheel casing side boundary beam and a wheel casing side boundary beam front end connecting plate assembly; the front longitudinalbeam is mounted on the sub frame mounting seat; the wheel casing side boundary beam is positioned above the front longitudinal beam; one end of the wheel casing side boundary beam front end connecting plate assembly is connected with the wheel casing side boundary beam; the other end of the wheel casing side boundary beam front end connecting plate assembly is connected with the front longitudinal beam to form a chamber structure and extends downwards to be connected with the sub frame mounting seat to form a mounting point; and the sub frame is mounted at the mounting point and connected with the sub frame mounting seat. The automobile little offset collision force transmission mechanism has the advantages that the design structure is simpler; as an automobile body is lightweight, the weight is reduced, and the cost is reduced; and as the wheel casing side boundary beam is not only connected with the longitudinal beam, but also a constituent part of the mounting point of the sub frame, and three force transmission paths are linked with each other, the failure risk of single-path force transmission is reduced, and the force transmission efficiency is enhanced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile small offset bumper force transmission mechanism and an automobile comprising the same. Background technique [0002] In recent years, with the rapid development of high-speed automobiles, automobile collision safety accidents occur frequently, and people pay more and more attention to automobile collision safety technology. There are many kinds of collisions in real life, one of which is a frontal small offset collision. In this type of collision, the frontal overlap between the barrier and the vehicle body is small, and the collision contact surface is outside the longitudinal beam. The longitudinal beam cannot absorb energy through crushing, thus This leads to a large amount of intrusion into the passenger compartment, which endangers the safety of the passengers. How to optimize the force transmission structure of the small offset collision at the front of the cabin ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art that the small offset bumper tends to bend the longitudinal beam first, which leads to the failure of the force transmission of the longitudinal beam, the single path of the force transmission, and the decrease in efficiency, and provides a small offset bumper for automobiles.
