Abstract
The utility model is an automobile active bumper which can reduce damage when in traffic collision, the bumper is integrated with two straight bars, wherein one surface of the straight bar is manufactured with serration, and the bumper can be inserted in an automobile frame to stretch freely, and a movable coupling mounted on the automobile frame is meshed with the serration faces of the straight bars under the action of springs. When in traffic collision, the violent friction between the serration faces and the movable coupling is utilized to reduce the speed of the automobile, thereby reducing the damage to persons and the automobile. The automobile active bumper also can be mounted at the tail portion of the automobile.
Description
Technical field
The utility model relates to the automobile collision preventing technical field, especially a kind of Federal bumper is made movable so that when colliding to consume the device that the part Impact energy reduces vehicle and personnel's injury.
Background technology
For traffic safety, automobile must the erection insurance thick stick.Current Federal bumper is directly to be fixed on the vehicle frame mostly, when taking place to collide, torsional deflection consumption part Impact energy by bumper/spoiler reduces the injury of bump to vehicle and personnel, when the speed of a motor vehicle is no more than 20 kilometers, this bumper/spoiler is an actv., when the speed of a motor vehicle surpasses 20 kilometers or when higher, Impact energy increases, because bumper/spoiler and vehicle frame are direct coupled, form very stiff and demanding, all Impact energies all are applied on the vehicle body by bumper/spoiler, very easily cause casualties and vehicle damage, and the high more injury of the speed of a motor vehicle is big more.
Summary of the invention
The problem that the utility model mainly solves provides and a kind ofly can consume a part of Impact energy earlier to reduce the anti-collision device for automobile that the speed of a motor vehicle comes minimizing personnel and vehicle to be hurt when colliding.
In order to address the above problem, the scheme that the utility model adopts is: automobile chassis frame both sides front end is made hollow square opening shape, also the straight thick stick and the bumper/spoiler of squarely connect together two sanction faces, zig-zag is respectively made in one side of two straight thick sticks, two straight thick sticks can insert in the hollow square opening of both sides vehicle frame front end, retractable, two dops that are fixed on the vehicle frame can rotate around the axis, be subjected to the serrated face interlock of pressure effect two movable chucks and the two straight thick sticks of spring, the source switch of a driving engine is contained in vehicle frame one side.
Owing to adopted such scheme, when taking place to collide, bumper/spoiler band two straight thick sticks shrink in vehicle frame, and the driving engine of thick stick shake-up always source switch is simultaneously turned off power supply, driving engine quits work.Bumper/spoiler continue to shrink, and at this moment the serrated face of two movable chucks and two straight thick sticks rubs, and consumes Impact energy, can not shrink up to bumper/spoiler, and this moment, collision began, but the speed of a motor vehicle slows down, and has reduced the injury of collision to personnel and vehicle.
Description of drawings
Figure of description is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail: bumper/spoiler 3 and two sanction faces are that two square straight thick sticks 2 connect together, zig-zag is respectively made in one side of two straight thick sticks 2, two straight thick sticks 2 are inserted in respectively in the square opening of both sides vehicle frame 1 front end, retractable, two movable chucks 6 are fixed on the both sides vehicle frame 1, and can be respectively rotate around separately axle 7, two movable chucks 6 under the pressure of two springs 4 with the serrated face interlock of two straight thick sticks 2, driving engine source switch 8 is contained in a side of vehicle frame 1.When taking place to collide, bumper/spoiler 3 is with two straight thick sticks 2 to shrink in vehicle frame 1 together, and thick stick 2 touches driving engine source switch 8 earlier always, turns off power supply, and driving engine quits work.Bumper/spoiler 3 and two straight thick sticks 2 continue to shrink, and at this moment the serrated face of two movable chucks 6 and two straight thick sticks 2 rubs, the consumption Impact energy, and the speed of a motor vehicle begins reduction at this moment, till bumper/spoiler 3 and two straight thick sticks 2 can not shrink.Can change the friction size of movable chuck 6 and straight thick stick 2 by the pressure of Luo silk 5 regulating springs 4.
The utility model also can be installed in the afterbody of car, when knocking into the back, reduces the injury that self is subjected to.
Claims (1)
1, a kind of automotive deck bumper/spoiler, by bumper/spoiler, Zhi Gang, movable chuck, spring, adjusting Luo silk and driving engine source switch are formed, it is characterized in that: the both sides front end of vehicle frame (1) respectively has a hollow square opening, insert in two square openings with bumper/spoiler (3) bonded assembly two straight thick sticks (2), the one side of two straight thick sticks (2) is made zig-zag, and with two movable chucks (6) interlock that is contained in vehicle frame (1) both sides front end one side, the afterbody of two movable chucks (6) is equipped with spring (4) and regulates Luo silk (5), and a side of vehicle frame (1) is equipped with driving engine source switch (8).
