Description
Technical field
The utility model relates to automotive field, is used for energy-absorbing and resistant to bending anticollision device when especially relating to a kind of automobile accident collision.
Background technology
Raising along with people's lives; Automobile has become the important vehicle of people's lives trip, announces according to the related media statistics, causes at the beginning of 2011; About 8,500 ten thousand of China's car owning amount; Become world's second largest automobile superpower, wherein personal car surpasses 1,200 ten thousand, and auto-industry have become national mainstay industry.
Yet when automobile increased, traffic accident took place frequently, and announced according to " Legal Mirror " statistics, and in years these 10 years calendar year 2001 to 2010, China has had nearly 900,000 people to die from all kinds of road traffic accidents, and the raising of safety traffic is very urgent.
For safety, on June 1st, 2004, " passenger protection of manned vehicle head-on crash " standard is formally implemented; On July 1st, 2006, " passenger protection of automobile side impact " and " collision fuel oil system safety requirements behind the manned vehicle " standard is formally implemented the second half year in 2006; China Automotive Technology & Research Center formally releases Chinese new car assessment routine; Be called for short C-NCAP, test event comprises three: the one, and positive 100% plyability obstacle Collision test, speed per hour is not less than 50 kilometers; The 2nd, positive 40% overlapping deformable obstacle Collision test, speed per hour is not less than 56 kilometers; The 3rd, the test of obstacle side collision is moved in deformable, and speed per hour is not less than 50 kilometers.The one the second is active safety, and the 3rd is passive security.The data of the dummy's in the collision post analysis car sensor are judged data such as acceleration-deceleration, deformation displacement, power, thereby are estimated the collision safety performance of a car, in the hope of priority protection driver and conductor's personal safety according to data; Crumple and distortion situation behind the analysis car body collision, whether car door can be opened, and projects such as A, B-pillar deformation situation with checking car body crew module's intensity, are run away in car in the hope of protection driver and conductor's living space and convenience.The J-NCAP of the EURO-NCAP of European Union and Japan also includes third party's item security of protecting the pedestrian, and the IIHS of the U.S. also comprises the passive security project of rear-end impact.
Various countries' test event such as following table:
And to state compulsory standard, each item qualitative requirement index that car production producer crashes and hits experiment, designing car body structure pointedly; And constantly to light-weight design; Reach up-to-standard achievement in the hope of the cost with optimum, therefore, each is variant for the collision prevention girders material of different automobiles and structure design etc.; The different automobile of same brand and high and low shift is also variant, and the material of luxury car and the cost of scheme are higher naturally.Each is variant though different collision prevention girders is because of many-sided different effects such as organization plan and materials, and purpose all is a buffering absorbing impact impact energy, reduces the distortion of vehicle occupant compartment, thus protection driver and conductor's personal safety.This also is the basic demand of automobile design.
Yet objectively, real-life contingency and not sum collision experiment chamber are identical, and when initiatively colliding thing is not to be merely body of wall; Possibly be the guideboard column, the automobile of exercising in opposite directions, stone; Trees or the like, angle when initiatively colliding and speed also are ccasuals, and breadboard test all is the low speed collision test; Generally cause the speed of a motor vehicle of casualty accident to be higher than 60km/h, on high speed, the speed of a motor vehicle is the twice of laboratory speed especially; And,, also do not force the passive security requirement of rear-end impact in China.On the other hand, after China's part joint brand manned vehicle on sale is introduced, much adaptability reform in various degree can be carried out, some security configurations maybe be simplified; This also can exert an influence to the safety performance of automobile, in recent years, media's report is just arranged; Owing to many-sided reasons such as costs, and China do not have mandatory requirement rear-end impact experiment, and the joint brand automobile of home-trade does not much have the rear anti-crash beam; Or foam block is only arranged, front anti-collision beam is also more and more thiner, beats the joint button greatly for the safety of automobile; And as long as the independent brand manned vehicle is because through the just ability list marketing of mandatory national standard, and its safety performance is failed the quantitative evaluation and the maximization of car production producer profit-push; And constantly develop to the direction of light-weight design, to a certain extent, can not ad infinitum improve the safety and the intensity of car load.Therefore, current, continuation improves the active safety and the passive security performance of automobile; With guarantee driver and conductor's life security, and reduce the damage rate of automobile in accident as far as possible, reduce property damage; For customer's car owner self, be very to hope with necessary.
Therefore, increasing people is concerned about the active and the passive satety of automobile accident collision, is not only to rest on the breadboard star data of C-NCAP; More pay close attention to the accident case in the daily life; So that develop into and install additional voluntarily or the street rod collision prevention girders, but because professional standards are uneven, theoretical analysis is improper; Design plan is not good enough; There is not the function of energy-absorbing after often causing reequiping, in case when crashing, the agent structure positions such as girder that the huge impact energy is delivered to automobile rigidly cause its distortion or damage; Thereby automobile is produced the damage that reparation is looked after and guided in bigger being difficult to, and driver and conductor's health more causes its joint or internal injury and very causes death and die because of the rigid of transmission of energy affacts human body.
Obviously, though the collision prevention girders of existing automobile can satisfy state compulsory standard,, in real life, the good energy of absorbing impact often, crashproof effect is unsatisfactory.
The utility model content
Though the utility model can satisfy state compulsory standard for the collision prevention girders that solves the prior art automobile; But, in real life, the good energy of absorbing impact often; The technical matters that crashproof effect is unsatisfactory provides a kind of collision energy-absorbing and counter-bending device.
