Abstract

The present invention discloses one kind of automobile safety equipment, which includes one collision contact device, one pushing device connected to the collision contact device, one chair sliding device connected to the pushing device and one brake device. In case of collision, the collision contact device is deformed to push the chair to slide backwards along the chair sliding device so as to protect the driver. At the same time, the pushing device pushes away the stopper in the brake device to eject two shovels for forced braking to avoid casualty of the driver caused by high automobile speed.

Description

Auto-safety mechanism

Technical field

The present invention relates to a kind of safety device, relate in particular to a kind of safety device that is used for automobile.

Background technology

At present, frequent accidents, the great majority that cause the navigating mate injures and deaths be extruded due to, seat on the automobile all is fixed on the car body, when automobile generation car accident, as: when automobile head-on is subjected to seriously clashing into, gross distortion can take place in Vehicular body front, and because chaufeur is fixed by the backrest of seat can not after move, cause chaufeur extruding to be caused injury or dead, the heel of Achilles that this phenomenon occurs is that exactly seat is to be fixed on the car body; Have in collision process again,, move equally and can cause after having only seat sometimes if collision is too serious, the chaufeur injures and deaths, the major cause that causes this phenomenon is in collision process, the brake gear of car itself is ineffective.

Summary of the invention

Technical matters to be solved by this invention provide a kind of when collision seat can move backward, having simultaneously can self-stopping auto-safety mechanism.

For achieving the above object, technical scheme of the present invention is: a kind of auto-safety mechanism, comprise collision contact device, thrust unit, seat sliding apparatus, brake gear etc., be fixedly connected with the collision contact device at automotive front end, between collision contact device and seat sliding apparatus, be fixed with thrust unit, between collision contact device and brake gear, be fixed with thrust unit.

As a kind of improvement, when deformation takes place because of collision in the collision contact device, seat unlatching switch on the described thrust unit will promote seat and slide backward along seat sliding apparatus, when deformation takes place because of collision in the collision contact device, the unlatching switch of the auxiliary brake on the described thrust unit will be pushed block in the brake gear open, and spades is ejected fast by compression spring and brakes under the traction of haulage cable.

As a kind of further improvement, when safety chair seats of car because of collision deformation took place when the collision contact device, thrust unit promoted seat and moves simultaneously behind the seat sliding apparatus that auxiliary brake carries out strong brake.

Owing to adopt technique scheme, when automobile generation car accident, as: when automobile head-on was subjected to seriously clashing into, gross distortion can take place in Vehicular body front, and since chaufeur by the backrest of seat be not fix but slippage backward, thereby chaufeur is not extruded cause injury or dead; If there is the speed of car very fast again, in collision process, because the people moves backward, intrinsic pin touches on the brake ineffective, and at this moment the strong brake device of Zeng Jiaing begins strong brake when seat retreats, thereby injures and deaths is reduced to minimum.

Description of drawings

Accompanying drawing is the structural representation of the embodiment of the invention.

The specific embodiment

As shown in drawings, a kind of auto-safety mechanism, comprise collision contact device 1, thrust unit 2, seat 3, seat sliding apparatus 4, brake gear 5, on the bumper/spoiler of automotive front end, be fixedly connected with collision contact device 1, it is described push pedal, between collision contact device 1 and seat sliding apparatus 4, be fixed with thrust unit 2, it is described push rod, two switches are arranged respectively above: seat is opened switch 21, auxiliary brake is opened switch 22, described seat sliding apparatus 4 comprises the upper saddle 41 that is fixed on described seat bottom, be fixed on the described car chassis and with described upper saddle 41 cooresponding lower sliders 42, be provided with pulley 43 between described upper saddle 41 and the lower slider 42, described auxiliary brake 5 comprises block 51, the spades 54 that controlled by block 51, and the tractive steel rope 53 when bonded assembly compression spring 55 and brake on the spades 54, push rod is opened seat and is opened switch 21 during collision, and seat 3 is moved behind lower slider 42; Simultaneously, open auxiliary brake and open switch 22, the block 51 in the brake gear 5 is removed, and ejects spades 54 fast and carry out strong brake under the elastic force of spring 55, simultaneously for prevent that fractureing from appearring in spades or other beyond, on each spades, be added with steel wire cable 53.

In the whole process of collision, the seat 3 that thrust unit 2 is promoted slides backward and thrust unit 2 is opened brake gears 5 and braked and carry out simultaneously along seat sliding apparatus 4.
