Abstract

The utility model discloses an automobile collision bumper protector. A main oil cylinder and a pressure relief oil cylinder are connected and communicated by an oil pipe; an auxiliary oil cylinder is also connected to the oil pipe and also communicated with the main oil cylinder through an oil pipe. Pistons and collision shafts are all arranged on the main oil cylinder and the auxiliary oil cylinder; hydraulic oil is filled in the main oil cylinder, the auxiliary oil cylinder and the oil pipes. A pressure relief piston and a pressure relief spring are arranged in the pressure relief oil cylinder. The utility model has the advantage that the automobile collision bumper protector can effectively relieve and reduce impact force when automobiles generate front or side collision; the volume of the oil cylinder is small; the utility model can be conveniently installed on miniature automobiles or cars.

Description

The buffering automobile collision protector

The utility model relates to a kind of buffer protection device that prevents auto against, belongs to vehicle anticollision fender guard field.

At present; prevent the device of frontal crash of vehicles in the prior art; just simply that a bulk strength is higher bumper clamp is on the crossbeam of automotive front end; though this mono-bumper system is simple in structure; in case but during automobile generation head-on crash; it can only collide with the collision thing with confronting the tough with toughnees; impulsive force in the time of can not slowing down or reduce collision effectively; thereby be easy to cause automobile and chaufeur to come to harm; therefore used bumper system on the automobile in the prior art, its protection effect that prevents frontal crash of vehicles is very undesirable.Be sort this problem out; once the someone had proposed to adopt two oil cylinder dresses that have a back lash spring onboard as the buffer protection device of automobile; the impulsive force when though the sort buffer fender guard has reduced frontal crash of vehicles effectively; but when bumping in the side for automobile; its protection effect that prevents side collision is just not ideal; and because it has adopted back lash spring in master cylinder; its oil cylinder volume can't be reduced greatly; therefore be difficult to it is installed in the front end of minicar or car, thereby exist the shortcoming that difficulty is installed in the use.

The purpose of this utility model is: provide a kind of simple in structure, be convenient to minicar or car and install and when front or side collision take place automobile, can both cushion the buffering automobile collision protector that reduces its impulsive force effectively, to overcome above-mentioned the deficiencies in the prior art.

The utility model is to constitute like this: it comprises master cylinder (1) and unloads compressing cylinder (2), master cylinder (1) with unload compressing cylinder (2) and be connected by oil pipe (3) and communicate, on oil pipe (3), also be connected with an auxilliary oil cylinder (4) by oil pipe, auxilliary oil cylinder (4) also is connected with master cylinder (1) by oil pipe, piston (5) and collision axle (6) all are housed on master cylinder (1) and auxilliary oil cylinder (4), and in master cylinder (1) and auxilliary oil cylinder (4) and in the oil pipe, all be full of hydraulic oil, release piston (7) and back lash spring (8) have been housed in unloading compressing cylinder (2).

Owing to adopted technique scheme, the utility model compared with prior art, have when front or side collision take place automobile, therefore the advantage of the impulsive force that is produced in the time of can cushioning and reduce collision effectively can protect automobile and chaufeur not to be subjected to serious injury preferably when collision; And, therefore can reduce the volume of oil cylinder greatly, thereby the utility model can be installed on minicar or the car easily owing in this practical master cylinder (1) and auxilliary oil cylinder (4), all do not adopt back lash spring.During use, available two cover master cylinders of the present utility model (1) and auxilliary oil cylinder (4) are fixed on the forward position of car chassis, and will assist oil cylinder (4) and be installed in respectively by higher position, side, to unload compressing cylinder (2) and be fixed on place suitable on the car chassis rear positions, the bottom of Federal bumper (9) is fixed on the collision axle (6) of master cylinder (1), position, middle and upper part at Federal bumper (9) is connected its collision axle with auxilliary oil cylinder (4) with bearing pin (10), and the distance that bumper/spoiler (1) is stretched out about the about 20cm of headstock gets final product.When automobile suffers front or side collision; its impact passes on the collision axle (6) of master cylinder (1) or auxilliary oil cylinder (4) by bumper/spoiler (9); its piston (5) is pushed in-oil cylinder hydraulic oil is pressed onto to unload by oil pipe (3) and promotes its release piston (7) in the compressing cylinder (2); thereby back lash spring (8) is compressed; can discharge like this and the impact when cushioning auto against; owing to unload the rear portion that compressing cylinder (2) is contained in car body; thereby the conduction by hydraulic pressure; its main impact acts on unloads on the compressing cylinder (2); the powerful impact force that headstock is suffered is released in the rear portion of car; thereby alleviate and reduced impact effectively, more reliably vehicle body and chaufeur are played a protective role.

Accompanying drawing 1 is a structural representation of the present utility model.

Embodiment of the present utility model: bumper/spoiler (9) can adopt the higher steel plate materials of intensity or other material to make specially, also can directly utilize the bumper/spoiler of former car, with master cylinder (1) with unload compressing cylinder (2) and be connected by oil pipe (3) and communicate, oil pipe (3) can adopt high pressure flexible tubing or high-pressure metal pipe to make, on oil pipe (3), connect a last auxilliary oil cylinder (4) by high pressure fuel pipe again, auxilliary oil cylinder (4) also can be connected with master cylinder (1) by connecting oil pipe, on master cylinder (1) and auxilliary oil cylinder (4), all adorn a piston (5) and a collision axle (6) respectively, in unloading compressing cylinder (2), load onto a release piston (7) and a back lash spring (8), and will all be full of hydraulic oil in master cylinder (1) and the auxilliary oil cylinder (4) and in the oil pipe.

Claims

1; a kind of buffering automobile collision protector; it comprises master cylinder (1) and unloads compressing cylinder (2); master cylinder (1) with unload compressing cylinder (2) and be connected by oil pipe (3) and communicate; it is characterized in that: on oil pipe (3), also be connected with an auxilliary oil cylinder (4) by oil pipe; auxilliary oil cylinder (4) also is connected with master cylinder (1) by oil pipe; piston (5) and collision axle (6) all are housed on master cylinder (1) and auxilliary oil cylinder (4); and in master cylinder (1) and auxilliary oil cylinder (4) and in the oil pipe, all be full of hydraulic oil, release piston (7) and back lash spring (8) have been housed in unloading compressing cylinder (2).
