Abstract
The utility model relates to the field of prevention of collision of automobiles, in particular to an energy absorbing device for front bumpers of automobiles. The technical scheme includes that the energy absorbing device for front bumpers of automobiles comprises an energy absorbing block, the energy absorbing block is a grooved block consisting of plates, and turned edges which are bent towards the outer side of a notch are disposed at the notch. In this way, the energy absorbing block which is in a grooved structure is stable in impact deformation after being subjected to impact pressure, and absorbed impact energy is increased obviously.
Description
Technical field
The utility model relates to the automobile collision preventing field, is specifically related to a kind of automobile front beam energy absorption device.
Background technology
The automobile front beam energy absorption device plays an important role in vehicle low speed collision, pedestrian protecting.In the vehicle low speed collision, energy absorption device absorbs most of collision energy; In pedestrian and the vehicle collision process, energy absorption device can effectively reduce shank and vehicle collision energy, protection pedestrian shank.At present, the front bumper energy absorption device that vehicle uses mostly is the energy absorbent block that foamed materials is made, yet the foamed materials energy absorbent block is out of shape unstable in collision process, and the collision energy of absorption is limited.
Summary of the invention
The purpose of this utility model provides a kind of stable automobile front beam energy absorption device that is out of shape, and can effectively improve the collision energy of absorption.
For achieving the above object, the utility model by the following technical solutions, a kind of automobile front beam energy absorption device, described energy absorption device comprises energy absorbent block, energy absorbent block is the groove-shaped frame that is made of plate, the notch place is provided with the flange of lateral buckling outside notch.
By above technical scheme, the energy absorbent block of bathtub construction is behind the pressure that is collided, and collision deformation is stable, and the collision energy of absorption significantly improves.
Description of drawings
Fig. 1 is the front view of this device;
Fig. 2 is the front view of energy absorbent block;
Fig. 3 is an energy absorbent block A-A direction cutaway view.
The specific embodiment
A kind of automobile front beam energy absorption device comprises energy absorbent block 10, and energy absorbent block 10 is the groove-shaped frames that are made of plate, and the notch place is provided with the flange 11 of lateral buckling outside notch.The flange 11 general welding or the bolted modes of adopting of energy absorbent block 10 are fixed on the crossbeam of automobile front beam, protect covering before the external packets of the base plate of the bottom land of energy absorbent block 10 is wrapped with.
Further, in order to make on the firm crossbeam that is fixed on automobile front beam of energy absorbent block 10, the flange 11 at the notch place of described energy absorbent block 10 is provided with one or more.
The side plate 12 that constitutes the cell wall of described energy absorbent block 10 is provided with one section or multistage bending place along the flute length direction, and obtain having the energy absorbent block 10 of pooling feature by extrusion forming, like this, energy absorbent block 10 can absorb more collision energy after the effect of being under pressure.
Further, be out of shape stablely in collision process for energy absorbent block 10, the collision energy of absorption is more, the described energy absorbent block 10 groove shape that is square, and the width of notch is slightly larger than the width of bottom land.
Described energy absorbent block 10 has a plurality of, evenly is arranged on the front bumper, and all adopts thin panel beating material.Thin panel beating material can absorb more collision energy in deformation process, and helps the panel beating moulding.
