Problems solved by technology

However, when the mass is reduced, it will also have a significant impact on the strength and stiffness of the anti-collision beam, which makes the passenger car less effective in protecting the vehicle and passengers when it is impacted by a collision.

Embodiment Construction

[0021] Please refer to Figure 1 to Figure 4 , the passenger car anti-collision beam assembly, including the anti-collision beam shell 1, the anti-collision beam shell 1 includes an arc-shaped shell formed by the continuous extension of the rectangular frame along the arc-line path, and the continuous wall of the arc-shaped shell is The thickness changes gradually from the middle of the arc path to both sides, and the truss structure 2 is filled in the anti-collision beam shell 1; a plurality of arc-shaped reinforcing ribs 3 are fixed equidistantly on one side facing the center of the arc line. , the arc shape of the rib 3 corresponds to the path of the arc line. An energy-absorbing box 4 is welded to both ends of the anti-collision beam shell 1 facing one side of the center of the arc line, and the interior of the energy-absorbing box 4 is filled with foamed aluminum material. The shell of the energy-absorbing box 4 is a frustum-conical shell whose wall thickness varies cont...

Abstract

The invention discloses a passenger car anti-collision beam assembly which comprises an anti-collision beam outer shell, the anti-collision beam outer shell comprises an arc-shaped shell body formed by continuously extending a rectangular frame along an arc line path, the continuous wall thickness of the arc-shaped shell body is in gradient change from the middle to the two sides of the arc line path, and the anti-collision beam outer shell is filled with a truss structure. Energy absorption boxes are fixedly arranged at the two ends of the side, facing the circle center of the arc line, of the anti-collision beam shell correspondingly, and the energy absorption boxes are filled with foamed aluminum materials. The passenger car anti-collision beam assembly has the advantages of being lightin weight, strong in energy absorption, high in specific energy absorption, large in bending strength, good in buffering performance, capable of effectively buffering forward and inclined impacts borne by a passenger car, capable of reducing maximum impacts borne by passengers to the maximum extent and capable of playing a good role in protecting cars and passengers.

Description

technical field [0001] The invention relates to the technical field of passenger car parts, in particular to a passenger car anti-collision beam assembly. Background technique [0002] The anti-collision beam is a device for the vehicle to withstand the impact force for the first time to reduce the collision and absorb energy. Therefore, a set of anti-collision beam components is installed at the front and rear of the bus. It is an important part of the vehicle safety structure and is required to have Good strength, rigidity, toughness and energy-absorbing performance, in order to absorb a large amount of impact energy while bearing the impact of collision, play a certain buffering role, and reduce the transmission of impact force to vehicles and passengers as much as possible. The existing passenger car anti-collision beam assembly can buffer the impact caused by the front of the vehicle to a certain extent. The quality of the passenger car anti-collision beam is strictly ...
