Description
Affiliated technical field
The utility model relates to the active anticollision device of self-propelled vehicle, and particularly motor vehicle collision energy-absorbing energy-dissipating device not only is fit to have body-chassis frame construction but also the suitable self-supporting body and the semi-integral body of rigid-frame.
Background technology
Automobile when offering convenience for human live and work, has also caused a large amount of personal casualty and property damage because of road traffic accident since 1886 come out.The accumulated number that car accedent is died from the whole world has surpassed the number of dying from war 20th century, and the whole world causes several hundred million people injured or disable because of mortality from automobile accidents's accumulative total surpasses 3,200 ten thousand people simultaneously till 2006.At present the whole world just in traveling automobile up to 7.2 hundred million, although extensively adopted safety methods such as safety strap, safety air bag, still have every year more than 70 ten thousand people to be killed in an automobile accident, 1000～1,500 ten thousand people are injured or disable, about 5,180 hundred million dollars of the annual economic loss that causes because of road traffic accident in the whole world.Because accounting for the automobile sum of the developing country of population advantage is increasing sharply, the total number of persons that car accedent is died from the whole world every year also will increase, expect global road fatalities in 2010 and will reach 1,000,000 people every year, wounded or disabled number surpasses 1,500 ten thousand, and the economic loss that cause because of road traffic accident global every year will be above 7,000 hundred million dollars.
Although positive bump taken place in traffic accident sometimes or knocked into the back; under the protection of safety strap and safety air bag; there is not personal casualty; but caused automobile impaired; even need overhaul, also may cause rejection of car when serious; bring massive losses for car owner and insurance company, this is the high main reason of automobile insurance.
Motor traffic accidents is when bringing death, permanent disability, the trip of returning people has brought inconvenience, nearly all person for driving a car and rider ran into the situation that causes traffic paralysis because of traffic accident, thereby cause people can't catch up with airplane flight or train, cause that people go to work, meeting and commercial negotiation are late or delay.
Vehicle safety is affecting government, enterprise, insurance company, person for driving a car, rider and household's the heart constantly, and the safety that how to improve automobile is the great scientific research task of pendulum in face of the universe.
At present automobile the safety measure of extensive employing be exactly body-restraining seat belt and safety air bag.The statistics of traffic accidents data show: fastening under the situation of body-restraining seat belt, Effective Vate of Protection can reach 43%～49%; Under the situation of air bag safe in utilization only, Effective Vate of Protection has only 18%; Under the duplicate protection of body-restraining seat belt and safety air bag, can play the better protection effect, but still personal casualty unavoidably occur.It should be noted that when safety air bag only clashes in the front and just can open to have no protective effect for such traffic accident of knocking into the back.
In order to protect occupant's safety; general dolly car anterior and afterbody as plastic deformation energy-absorbing energy-dissipating district; making the space invariance shape at occupant place to greatest extent, but still can not guarantee occupant's safety sometimes, this in addition mode is not suitable for cab-over-engine vehicle.
Many for this reason people have carried out big quantity research to automobile collision preventing, up to the present disclose hundreds of patents, and for example ZL200320119672.1 discloses safety lever front extensible automobile automatic collision safety device; ZL00205037.4 discloses the energy-storing automobile anticollision device; ZL03248553.0 discloses automobile head anticollision safety device; ZL96233407.3 discloses automobile collision preventing and has hit damping; ZL02277281.2 discloses the anticollision device that knocks into the back; ZL90105824.6 discloses auto against energy-absorbing damping safety lever.These crashproof measures can be divided into following several mode: utilize the compression spring energy-absorbing; Utilize hydraulic fluid cylinder energy-absorbing; Adopt air bag or tire energy-absorbing; Or in implementation process, these modes are made up.
Why the anticollision device of these patent disclosures can not obtain promotion and application, and its reason is to have following problem:
1) self-propelled vehicle vehicle body in knockout process all is in compressive state, and one side will cause motorcar body to deform and damage, and may cause driver and crew's a space of taking advantage of to be squeezed on the other hand, the critical people's of possibility life security when serious.
2) can only can't consume energy by energy-absorbing, promptly can not consume huge expenditure of energy or part, the problem of bringing thus is may backward acceleration occur after the automobile sharp impacts and make the occupant suffer bigger injury, even the car of being dished out causes personal casualty outward.
3) stressed spring of several whiles or can't absorb huge energy, or can't adapt to little collision.
4) hydraulic damping device is connected safety lever and vehicle beam or crossbeam with spring vibration damper while in-parallel, can not plays a role simultaneously, spring vibration damper can't play a role at all generally speaking, and its reason is that the compressibi1ity of fluid is very little.
5) it is impaired that any bump all can cause automobile, causes car owner and insurance company to bear economic loss.
