Abstract
The utility model provides an on the basis that new forms of energy have longeron hybrid or pure electric vehicles buffering energy -absorbing device is having longeron hybrid or pure electric vehicles chassis structure, it replaces mounted bumper to introduce the new subassembly of light buffering energy -absorbing device, the car security improves, can alleviate or even hit or knock into the back the traffic accident in the twinkling of an eye before the elimination emergence basically, the two kinds of injuries to conductor and driver that lead to, the secondary damage that to be the impact force arouse to people's once injury with because of the acceleration, also can alleviate vehicle structure simultaneously, battery pack's destruction especially, realize triple technological effects.
Description
Technical field
The utility model relate to new-energy automobile resist knock into the back and frontly to hit, anti-battery component hit security technology area on fire, is specifically related to the crash energy absorption equipment that a kind of new forms of energy have longeron hybrid power or pure electric automobile.
Background technology
For improving the safety of new forms of energy hybrid power or pure electric automobile; still on chassis, be configured with the longeron made of high strength light material; but mostly continue to use the weak rigid construction material of buffering energy-absorbing and make bumper/spoiler; high, drive at moderate speed in knock into the back or before hit time, do not have the effect protecting people and car.The utility model patent; for the problems referred to above; contriver's exploitation, on " carbon fiber composite material and strengthen the forward and backward safe beam of automobile of metal polyporous material " (patent No. 2013207815555) patent basis of using for gasoline automobile of shaping; through developing and improving the lightweight crash energy absorption equipment developed a kind of new forms of energy and have longeron hybrid power and pure electric vehicle to use; high, drive at moderate speed; have and significantly improve the anti-of vehicle structure and knock into the back and front hit ability; while protection people, also protect the battery component system of car.
Summary of the invention
Technical problem to be solved in the utility model is: on the basis having longeron hybrid power or pure electric automobile chassis structure, introduce lightweight crash energy absorption equipment New Parent and replace the existing bumper/spoiler (or collision prevention girders) installed on longeron, improve vehicle safety, hit before can alleviating even basic elimination generation or knock into the back traffic accident moment, the two kinds of injuries to driver and conductor caused, namely impulsive force is to the once injury of people and the secondary injury that causes because of acceleration/accel, also can alleviate vehicle simultaneously, the particularly destruction of battery component, realizes triple technique effect.
For realizing above-mentioned technique effect, on No. 2013207815555 patent bases, there is the feature of longeron hybrid power and pure electric automobile body construction for new forms of energy, having carried out following improvement:
The first, the rigidity bumper/spoiler that existing hybrid power or pure electric automobile are installed on longeron is used instead lightweight crash energy absorption equipment, significantly improve high, drive at moderate speed in occur before the impact resistant capability of hitting or knocking into the back, available protecting driver and conductor is from injures and deaths and the destruction alleviated automobile batteries assembly;
The second, energy absorber material is honeycomb aluminum by foamed aluminium Yi, and honeycomb aluminum is compared with foamed aluminium, and its front bulk compressibility is up to more than 90%, and under same volume condition, the energy absorption of honeycomb aluminum is greater than foamed aluminium, is more suitable for adopting in forward and backward safe beam;
Three, be protection people and car (mainly battery component), the buffering energy-absorbing of safe beam be designed to 70KJ, increase 20-40KJ than the energy absorption of No. 2013207815555 patents, with increasing of energy absorption, the corresponding increase about 20% of energy absorber volume.
For meeting above-mentioned technical requirements, take technical scheme be:
New forms of energy have the crash energy absorption equipment of longeron hybrid power and pure electric automobile to resist to knock into the back and the front crash energy absorption equipment hit, it is characterized in that it combines by being arranged on front safe beam and rear safe beam on longeron; Case, the bottom girder carbon fiber composite material of forward and backward safe beam make, energy absorber about 0.1-0.4mm, proportion 0.3g/cm
3, bulk compressibility reach more than 90% hexagonal honeycomb aluminum do; Energy absorber height 100 ㎜, design energy absorption 70KJ.
Accompanying drawing explanation
Fig. 1 is for having longeron hybrid power or pure electric automobile crash energy absorption equipment structural representation.
Detailed description of the invention
See Fig. 1,1 is carbon fiber composite material case, and 2 is carbon fiber composite material bottom girder, and 3 is honeycomb aluminum energy absorber; See A-A section in Fig. 1, wherein main energy absorber 3 line of centers faces the line of centers installation of the forward and backward longeron of automobile, distributes about the line of centers of auxiliary energy absorber then facing to forward and backward safe beam; In the front bottom girder and rear bottom girder of forward and backward safe beam, by design-calculated requirement and position, adopt adhesive approaches, by below energy absorber with bottom girder bottom adhesion, with case adhesion above energy absorber, be configured to forward and backward safe beam, then link together with the front end of bolt and automobile longitudinal girder, rear end.
