Front energy absorbing device for vehicle frame and vehicle frame and automobile having the same

Abstract

The invention discloses a front energy absorption device for a frame and the frame or a car employing the same. The front energy absorption device comprises a front anti-collision beam, wherein the front anti-collision beam comprises a body, a middle plate and two energy absorption boxes; the body comprises an upper plate, a lower plate, a first side plate and a second side plate; the lower plate is arranged below the upper plate; the first side plate and the second side plate are connected between the front end of the upper plate and the rear end of the lower plate respectively; the middle plate is arranged between the upper plate and the lower plate and connected with the first side plate and the second side plate respectively; the middle plate, the upper plate and the lower plate have roughly the same thickness; and the two energy absorption boxes are connected to the rear part of the front anti-collision beam in a spaced way. According to the front energy absorption device, the upper plate, the middle plate and the lower plate of the front anti-collision beam are designed to have the same thickness, so that the front anti-collision beam is more easily extruded and bent; the lightweight design is realized on the premise of meeting the collision energy absorption requirement; and through the arrangement of the energy absorption boxes, the energy absorption effect of the front energy absorption device is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a front energy-absorbing device for a vehicle frame, a vehicle frame and a vehicle with the same. Background technique [0002] As far as automobile safety is concerned, in addition to the mandatory standards and regulations formulated by various countries, there are star rating (NCAP) requirements and insurance (RCAR) requirements formulated by various countries; Because of its great market influence, which directly affects the market sales of its vehicles, it has been widely concerned by automobile manufacturers. [0003] In order to improve customer satisfaction and vehicle market competitiveness, front anti-collision beams and live-loaded energy-absorbing boxes are generally added to the front of the frame, and it is required that the anti-collision beams and energy-absorbing boxes are easy to replace after the vehicle collides at low speed, so as to improve the vehicle Insurance ...

AI Technical Summary

Problems solved by technology

[0004] The thicknesses of the horizontal upper plate, middle plate and lower plate in the front anti-collision beam of traditional vehicles are not equal to each other, which brings inconvenience to the bending process, specifically, during the bending process, the thickness of the middle plate is greater than that of the upper plate and lower plate When the thickness is high, the force on the middle plate is relatively large, and the force on the upper and lower plates is small, and the processing is easy to lose stability. Moreover, although increasing the thickness of the middle plate can increase the energy absorption effect, it increases the weight of the front anti-collision beam, thus making it lighter. Insufficient Quantitative Design

In addition, the traditional cross-sectional structure of the front anti-collision beam is relatively regular, which is not conducive to the shape design and layout space design of the vehicle front
