Abstract

A kind of Collipsion preventor of the utility model belongs to buffer field, it is to be made of bumper and crossbeam, one end of buffer is secured in the front end of crossbeam, the buffer is the cavity of an inner hollow, the other end of buffer is connected to bumper by piston rod, the front end of bumper is equipped with crash sensor, is equipped with electromagnet on bumper and buffer relative position, upper cover of piston rod has spring；Cavity built-in piston block, piston block connect piston rod；Gas generator is fixed on the inner wall of cavity, gas generator connects air bag.The utility model structure is simple; design is reasonable; pass through setting spring and the damping of high-speed double electromagnet first layer; air bag is set and realizes second layer damping; soft collision is converted by hard collision; impact force is absorbed to greatest extent, has good protective effect to collision partners, and collide rear vehicle resilient.

Description

A kind of Collipsion preventor

Technical field

The utility model belongs to buffer field, in particular to a kind of Collipsion preventor.

Background technique

The high speed development of auto industry brings huge convenience to the life of the mankind, while also bringing and being particularly acute Traffic accident.Most vehicles keep out shock when collision using the structure for improving bumper or external installation anticollision device, collision-prevention device Power plays certain protective effect to vehicle itself and occupant, but this collision is hard collision, for slight Collision can also shield, and such as occur big collision, and car body can occur severely deformed, and impact force is not delayed effectively Solution, release, eventually lead to the injures and deaths of personnel.

Summary of the invention

The purpose of this utility model is exactly to provide a kind of Collipsion preventor to overcome the above problem.

A kind of Collipsion preventor of the utility model, is made of bumper and crossbeam.It is secured in the front end of crossbeam One end of buffer, the buffer are the cavity of an inner hollow, and the other end of buffer is connected to guarantor by piston rod Dangerous thick stick, the front end of bumper are equipped with crash sensor, are equipped with electromagnet on bumper and buffer relative position, on piston rod It is cased with spring；Cavity built-in piston block, piston block connect piston rod；Gas generator, gas are fixed on the inner wall of cavity Generator connects air bag.

As a further improvement of the utility model, at least provided with two crash sensors on bumper.

Bumper is fixedly connected with piston rod as a further improvement of the utility model, buffer and the fixed company of crossbeam It connects.

Bumper is equipped with the magnetic pole phase of electromagnet with buffer relative position as a further improvement of the utility model, Together.

Gas vent is equipped on buffer and air bag as a further improvement of the utility model,.

Compared with the prior art, the utility model has the following advantages:

The utility model structure is simple, and rationally, by setting spring and the damping of high-speed double electromagnet first layer, gas is arranged in design Capsule realizes second layer damping, converts soft collision for hard collision, absorbs impact force to greatest extent, have to collision partners Good protective effect, and collide rear vehicle resilient.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of Collipsion preventor of the utility model.

Specific embodiment

With reference to the accompanying drawing to a kind of Collipsion preventor of the utility model, it is described further:

As shown in Figure 1, a kind of Collipsion preventor of the utility model, is made of bumper 1 and crossbeam 2.In crossbeam 2 Front end be fixedly connected with one end of buffer 4, the buffer 4 is the cavity 8 of an inner hollow, buffer 4 it is another End is connected to bumper 1 by piston rod 3, and bumper 1 is fixedly connected with piston rod 3, and the front end of bumper 1 is equipped at least two The threshold value of crash sensor 5, two crash sensors 5 is different, and bumper 1 is identical equipped with magnetic pole as 4 relative position of buffer Electromagnet 6, be cased with spring 7 on piston rod 3, the both ends of spring 7 be against on bumper 1 respectively and buffer 4 on；In cavity 8 Piston block 9 is set, piston block 9 connects piston rod 3, and the body of rod of piston rod 3 passes through buffer 4, retractable；In cavity 8 Gas generator 10 is fixed on wall, gas generator 10 connects air bag 11, and after air bag 11 is inflated, outer wall should correspond to and be against work On chock 9, it is equipped with gas vent on buffer 4 and air bag 11, when gas generator 10 is that air bag 11 is inflated, in buffer 4 Gas be discharged by itself gas vent, guarantee air bag 11 normally inflate, after vehicle collision, air bag 11 pass through itself row of exhausting-gas hole Gas out avoids the unconfined inflation of gas generator 10, causes air bag to explode, air bag can also be recycled.

When slight impact, 1 compressed spring 7 of bumper occurs, signal is transmitted to controller by the small crash sensor of threshold value, is controlled Device processed is respectively turned on the electromagnet 6 on bumper 1 and buffer 4, since the magnetic pole of electromagnet 6 is identical, mutually exclusive, impact force Bigger, electromagnet 6 is apart from closer, and repulsive force is bigger, while the resistance of spring is bigger, effective buffering percussive force；Occur tight When colliding again, the big crash sensor of threshold value starts simultaneously is transmitted to controller for signal, and controller starting gas generator 10 is Air bag 11 is inflated, and piston block 9 strikes on air bag 11, is carried out secondary buffer to impact force, is played a very good protection.
