Abstract

The invention relates to an object collision protector, in particular to a cutting type energy-absorbing object collision protector. It is characterized by that it is formed from mutually slide-fitted components, and on the slide-fitted surface a toothed projection is set. Thus, when the components slide relatively, a certain number of tooth-shaped protrusions are continuously cut, so that collision energy is absorbed, namely, rigid impact between objects is finally solved, and the objects are protected from rigid impact. The invention has wide application range, can be applied to various vehicles and various parts of the vehicles, can also be applied to other collision protection such as seats, piers, docks, airplanes, spacecrafts, ships and the like, can realize the omnibearing protection effect, has simple structure, more thorough energy absorption and good application effect, and is easier to standardize in popularization and application.

Description

Cutting type energy-absorbing object collision protector

Technical field

The present invention relates to a kind of object collision protector, particularly a kind of cutting type energy-absorbing object collision protector.

Background technology

The existing object collision protector mainly contains common protection thick stick, safety air bag, safety strap, ABS anti-lock braking system disclosed 97208274.3,00225135.3 patent of Chinese patent of unifying such as being used on the automobile.Common protection thick stick only has faint protective effect under the vehicle low cruise; And safety air bag can only be protected the people, can not protect car, and the price height, complex structure, and disposable use, what have misoperation may wait deficiency; Safety strap is little to people's protective effect, can not protect car; The ABS antiblock device is the price height not only, and complex structure is difficult in maintenance, and the accident protection effect is limited.Has only the above-mentioned automobile safety automatic protector patent outstanding person in this field at last, but its structure and function etc. also do not reach thoroughization and optimization, the endergonic structure design of 3-4 screw of its cutting can't reach the best applications state, it can not realize making an initiative sally in addition, be that protector can not be desired to stretch out earlier certain distance and meets collision, just be difficult to dissolve collision impact power more than the self-propelled vehicle high speed, promptly lack sufficiency and thoroughness on the impulsive force dissolving from protector itself; Simultaneously, adopt screw as collision cutting absorption cell, because identical with the common standard screw, so the confusion that has keeping, uses and keep in repair if misapplied the screw of other strength grade, can cause the uncertainty on the crash protection, its loss is well imagined.

Summary of the invention

The technical problem to be solved in the present invention is: at the deficiency of above-mentioned technology existence; the object of the present invention is to provide a kind of cutting type energy-absorbing object collision protector; can play protective effect more convenient, more effective, more up hill and dale to object collision; be easy to realize normalisation simultaneously, conveniently take care of, use and keep in repair.

Solving the technical scheme that technical matters of the present invention adopts is: cutting type energy-absorbing object collision protector provided by the invention, form by the member of mutual bearing fit, and be provided with the detent projection thing along the bearing fit face.

According to technique scheme; because the present invention is made up of the member of mutual bearing fit; and be provided with the detent projection thing along the bearing fit face; like this when the member slide relative; by the detent projection thing of continuous cutting some, thereby absorb collision energy, promptly finally dissolve the rigid impact between object; make object can not be subjected to rigid shock, to protect this object.

Beneficial effect of the present invention: cutting type energy-absorbing object collision protector provided by the invention, can absorb collision energy effectively, protect effect effectively thereby play; Applied range not only can be applied on the various vehicles, on each position of vehicle, but also can be applied to other as on the crash protections such as seat, bridge pier, harbour, aircraft, spacecraft, boats and ships, can realize omnibearing protection effect.Therefore, the present invention has and has wide range of applications, and simple in structure, energy-absorbing is more thorough, and effect is good, and is easier to normalisation on applying.
