Description
Technical field
The invention belongs to a field in automotive safety technology.
Background technology
Automobile on road surface gets more and more, and traffic accident is also more and more frequent.According to statistics, in vapour collision case, the chance rate that vehicle front collides is the highest, and almost in each vapour collision case, the automobile of the rarest side is frontal collisions.Therefore, the emphasis of automobile collision preventing considers it is frontal collisions; During galloping, due to the effect of inertia of material, automobile and passenger thereof store huge inertia energy.Just in case at this moment automobile generation frontal impact, these energy abrupt releases, will produce huge impulsive force, its consequence is hardly imaginable.Because during frontal crash of vehicles, the speed of a motor vehicle reduces instantaneously, even replys quiescence.Passenger inside the vehicle is in this process, and will bear huge impulsive force forward, will be therefore likely injured.In prior art, in order to when automobile generation head-on crash, extraneous impulsive force can be relaxed, all in the front and back of the longeron of automobile chassis frame, crashproof girder steel and low speed energy-absorption box are installed.Wish that it is when clashing into generation, the distortion leading to metal carrys out apparatus with shock absorbing.Reduce the impulsive force that in car, each occupant bears, as far as possible protection automobile and passenger.But, because crashproof girder steel and low speed energy-absorption box front and back are altogether always apart from 20-30 centimetre of only having an appointment.Therefore, its geometry deformation size is very limited, and the space of distortion is very limited, also very limited to the protection of automobile and passenger.Reason is very simple, and in the dispose procedure of inertia energy, under the prerequisite of same inertia energy, ranging coverage is longer, and the impulsive force of generation is less, otherwise then anti-.The deformation space of obvious 20-30 centimetre is far from being enough.In prior art, not enough for mending this, invent safety air bag.But, automobile is not safety air bag is loaded onto at each seat, moreover the expansion of safety air bag self also has certain danger.Although safety air bag quality is little, speed when launching instantaneously is high, and this velocity of impact is not a peanut for human body.According to the statistics of some national highway safety management departments, while safety air bag often saves 100 passenger life in collision traffic accident, also because of the inappropriate expansion of air bag and the mal seating position of occupant and sitting posture, unfortunately 57 occupants are caused to lose life.Above-mentioned these are all after car accident occurs, and in the accident of particularly clashing in vehicle front, always have injured even one of the main causes of death of so much people.Visible, the effort of indented material is also not as people's will.How to allow automobile generation frontal collisions time, the inertia energy that the passenger in compartment has, can obtain discharging as far as possible slowly, reduce impact dynamics be purpose of the present invention.
Summary of the invention
For making automobile when there is head-on crash, the inertia energy in compartment can be extended, release distance over time and space, reducing the impact dynamics that in compartment, personnel bear, protect the full complement in compartment more preferably.This invention takes following technical measures: automobile primary will be divided into vehicle frame 1 and 2 liang, compartment major part, and compartment 2 horizontal anomalous movement is connected on vehicle frame 1, and energy dissipating bar 3 is housed between compartment 2 and vehicle frame 1.Assemble together with the steel pipe socket that described energy dissipating bar 3 differs primarily of many diameters and length, large will the growing of the diameter group that diameter of steel tube is little.All steel pipe sockets are the alignment of rear one end together, and is fixedly mounted on compartment 2 through behind the hole on bearing 6.Bearing 6 is contained on vehicle frame.The other end of each steel pipe is equipped with termination 5, and the external diameter of termination 5 is greater than the internal diameter of upper class steel pipe.Steel pipe slippage is stoped to go out bearing 6 when termination 5 is moved for compartment 2 forward horizontal.
Owing to being horizontal anomalous movement annexation between vehicle frame 1 and compartment 2, between vehicle frame 1 and compartment 2, energy dissipating bar 3 is housed simultaneously, so when automobile generation head-on crash, compartment 2 can relative to vehicle frame 1 forward vertical equity move.This vertical equity displacing force forward, can break the steel pipe on energy dissipating bar 3 from big to small one by one.Often break the inertia energy that a steel pipe all will consume the last part in compartment 2, in the whole vertical equity shift motion in compartment 2, all steel pipes can be broken.Therefore it can consume the inertia energy that compartment 2 has widely, and when making collision, the impulsive force that compartment and passenger thereof bear reduces greatly, effectively protects each passenger in compartment; On the other hand, the present invention does not have the danger produced during air-bag deployment, but can protect all occupants in compartment, have more preceence by contrast.

Detailed description of the invention
For making automobile when there is head-on crash, the release distance of the Time and place of compartment inertia energy had at that time can be extended, reduce the impact dynamics that in compartment, personnel bear, protect the full complement in compartment more preferably.This invention takes following technical measures: automobile primary will be divided into vehicle frame 1 and 2 liang, compartment major part, and compartment 2 horizontal anomalous movement is connected on vehicle frame 1, and energy dissipating bar 3 is housed between compartment 2 and vehicle frame 1.When automobile generation frontal impact, compartment 2 can horizontally vertically move relative to vehicle frame 1.Steel pipe on energy dissipating bar 3 can be broken from big to small one by one.Often break the inertia energy that a steel pipe all will consume the last part in compartment 2, in the whole vertical equity shift motion in compartment 2, all steel pipes can be broken.Therefore it can consume the inertia energy that compartment 2 has widely, and when making collision, the impulsive force that compartment and passenger thereof bear reduces greatly, effectively protects each passenger in compartment, thus also greatly alleviate their injured degree; On the other hand, the present invention does not have the danger produced during air-bag deployment, but can protect all occupants in compartment, have more preceence by contrast, as shown in Figure 1 and Figure 2.
Vehicle frame 1 described in the application is connected with the horizontal anomalous movement between compartment 2, refers to that compartment 2 is relative between vehicle frame 1, can carry out the annexation of horizontal shifting.The mode that can realize this annexation is a lot, such as, use that the radial type of rocking arm connects, sleeve type connects, buckle-type connection etc.The horizontal anomalous movement of this example connects, and has selected sleeve type connection mode.It is by below compartment 2, the back rest that hard-wired four square tubes 4 are enclosed within vehicle frame 1 realizes, as shown in Figure 2.Four square tubes 4 are distributed in four angles in compartment 2, and they are enclosed within the longeron of vehicle frame 1 simultaneously.Square tube can be with the front and back longitudinal sliding motion on longeron of same compartment 2.
Energy dissipating bar 3 is the vitals consuming compartment 2 inertia energy, assembles together with the steel pipe socket that it differs primarily of many diameters and length.Large will the growing of the diameter group that diameter of steel tube is little, as shown in Figure 3.All steel pipe sockets are the alignment of rear one end together, and is fixedly mounted on compartment 2 through the hole on bearing 6.The other end of each steel pipe is equipped with termination 5, and termination 5 is fixedly mounted on the external cylindrical surface of steel pipe, and the external diameter of termination 5 is greater than the internal diameter of upper class steel pipe.Steel pipe slippage is stoped to go out bearing 6 when termination 5 is moved for compartment 2 forward horizontal.
Principle of work of the present invention: galloping is on highway, and full car comprises passenger and all stores huge inertia energy.When the moment of automobile generation frontal impact, what first withstand shocks is vehicle frame 1.Owing to being horizontal anomalous movement annexation between compartment 2 and vehicle frame 1, so compartment 2 creates parallel motion forward relative to vehicle frame 1, create huge pulling force simultaneously.Because the termination 5 of the outmost steel pipe of energy dissipating bar 3 is closest to bearing 6, it makes outmost steel pipe slippage cannot go out bearing 6.First huge impact tension is broken this steel pipe outmost for energy dissipating bar 3.Compartment 2 continues to reach, and bearing 6 is and then encountered in the termination of the Article 2 steel pipe that diameter is slightly little, and it also prevents the slippage of this steel pipe, and result is that compartment 2 is also broken this steel pipe.It is exactly that steel pipe on energy dissipating bar 3 is successively pulled off one by one that time continues.In this process, often break a steel pipe, the inertia energy on compartment 2 will consume some.When whole steel pipe is pulled off, the inertia energy on compartment 2 is taken advantage of very few, and therefore, the impact dynamics that the passenger on compartment bears because of automobile impacting also lowers greatly, makes them obtain actv. protection.
