Vehicle rear floor front beam

Abstract

The invention discloses a vehicle rear floor front beam which comprises a bottom plate, a vertical plate, a first turned edge, inclined faces, liquid leakage holes, trim seat clamping holes, main positioning holes, auxiliary positioning holes and carpet installation holes. A protruding arched structure is arranged in the middle of the bottom plate. The bottom of one side of the bottom plate is fixedly connected with the top of the vertical plate through welding. The two ends of the arched structure are fixedly connected with the vertical plate through the inclined faces respectively. The liquid leakage holes are formed in the middles of the two sides of the vertical plate respectively. The first turned edge is fixed to the bottom of the vertical plate. The trim seat clamping holes are formed in the two sides of the arched structure respectively. The main positioning holes are formed in the positions, on one sides of the trim seat clamping holes, of one end of the arched structure. Through the inclined faces, the stress borne by the position, at the arched structure, of the joint of the vertical plate and the bottom plate is remarkably reduced in the stamping process, it is avoidedthat the joint of the vertical plate and the bottom plate is prone to breakage and corrugation under the concentrated stress during stamping, and therefore the forming rate and structural strength ofan outer plate of the vehicle rear flow front beam are improved.

Description

technical field [0001] The invention relates to the field of brackets on the rear floor front crossbeam, in particular to an automobile rear floor front crossbeam. Background technique [0002] With the continuous development of automobile technology, users have higher and higher requirements for automobiles, and pay more attention to the safety performance of automobiles. Therefore, improving the safety performance of automobiles is particularly critical in the design and development process of automobiles. The beam is an important part of improving the safety performance of the car, and it can play a key role in side collisions. [0003] However, in the existing automobile rear floor front beam, the bottom plate and the vertical plate are fixedly connected by welding, and the angle between the bottom plate and the vertical plate is 90 degrees, so that the stress on the connection between the vertical plate and the bottom plate increases during the stamping process , it is...

Problems solved by technology

[0003] However, in the existing automobile rear floor front beam, the bottom plate and the vertical plate are fixedly connected by welding, and the angle between the bottom plate and the vertical plate is 90 degrees, so that the stress on the connection between the vertical plate and the bottom plate increases during the stamping process , it is easy to crack and wrinkle at the junction of the vertical plate and the bottom plate due to stress concentration during stamping, which reduces the forming rate and structural strength of the outer plate of the front cross member of the rear floor of the car. Therefore, we propose a car rear floor front beam
