Abstract

The invention discloses a kind of energy-absorbing air bag for bumper, including:Airbag body, it is installed on the front side of bumper, and the top and the bottom of the airbag body are provided with stair-stepping fold;And damping stomata, it is located at the sidepiece of the airbag body.The energy-absorbing air bag is when colliding, and due to its less rigidity, good buffering deformability, reduces the acceleration of collision, improves occupant, pedestrian, the security of automobile.

Description

Energy-absorbing air bag for bumper
Technical field
The present invention relates to automotive safety facility, more particularly to a kind of energy-absorbing air bag for car insurance bar.
Background technology
In the front portion of automobile, the bumper to be shielded to automobile is typically provided, when car collision, by insuring Bar is stopped, so that automobile avoids being knocked.But after bumper collides, be easier to bend or be broken, cause to protect Dangerous thick stick can not be protected to automobile.The material rigidity of bumper is higher, and larger acceleration can be produced when colliding, unfavorable In occupant and vehicle body safety.In addition, when with more can be due to its larger rigidity and less deformation during pedestrian collision so that Pedestrian bears great impact force, causes serious consequence.
Also occur the measure protected to bumper in recent years, in bumper installed in front foam energy absorbent block, but steep Foam is easier to damage when hitting, and buffering effect is poor.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
The content of the invention
It is an object of the invention to provide a kind of energy-absorbing air bag for bumper, and foam energy-absorbing is used so as to overcome The shortcomings that block is easier to damage when hitting.
To achieve the above object, the invention provides a kind of energy-absorbing air bag for bumper, including:Air bag sheet Body, it is installed on the front side of bumper, and the top and the bottom of the airbag body are provided with stair-stepping fold;And damping stomata, It is located at the sidepiece of the airbag body.
Preferably, the airbag body is curved.
Preferably, the radian of the arc is 10-35 °.
Preferably, the inside of the airbag body is made up of multiple small air chambers communicated.
Preferably, the airbag body is fixed on the front side of the bumper by mounting pin.
Preferably, the damping stomata is two, is respectively arranged on the both sides of the airbag body.
Compared with prior art, the present invention has the advantages that:
1. the energy-absorbing air bag in the present invention, after the compression that is collided, airbag body is compressed, discharged by damping stomata Portion gas in airbag body, good buffering deformability is played to protect car insurance bar, and can rely on air bag sheet The elasticity of the stepped fold of body returns to the original form.
2. energy-absorbing air bag has good buffering effect due to using air as compressed media.
3. collision energy can be converted into gas internal energy and discharge airbag body by damping stomata, surrounding environment is dissipated in In.

Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention Shield scope is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members Part or other parts.
As shown in Figures 1 to 4, according to a kind of energy-absorbing air bag for bumper of the specific embodiment of the invention, Including:Airbag body 2 and damping stomata 3, airbag body 2 are inside it using having certain thickness elastic caoutchouc to be made Air cavity, full of air, more specifically, the inside of airbag body 2 is made up of multiple small air chambers communicated, and multiple small air chambers may be used also Play when airbag body 2 is compressed, the effect of row buffering is entered to compressed air stream, airbag body 2 is fixed on automobile by mounting pin 1 The front side of bumper, in order that the airbag body 2 is preferably bonded with the front side of bumper, airbag body is set in arc Shape, the radian of arc is 10-35 °, is easy to make full use of the confined space around bumper.As shown in figure 4, in airbag body 2 Top and the bottom are provided with stair-stepping fold 4 so that airbag body 2 is easier to restore to the original state when compressing;Damping stomata 3 is located at The sidepiece of airbag body 2, can be preferably vented, damping stomata 3 is equipped with the end face of the both sides of airbag body 2.Damping Stomata 3 is by test in advance and calculates, and its size can ensure to exclude reasonable amount in time when collision dynamics reaches to a certain degree The gas air bag that to be extruded inside pressure be unlikely to excessive, rigidity increase is unlikely to excessive, then plays control and touches Hit the effect of dynamics.
In use, when colliding especially with pedestrian collision, airbag body is compressed, and rigidity increases to necessarily During degree, by damping the exhaust of stomata, air bag rigidity and collision dynamics can be preferably controlled, reduces the acceleration of collision, It can play a part of protecting pedestrian, occupant, improve the security of automobile.
The description of the foregoing specific illustrative embodiment to the present invention is to illustrate and the purpose of illustration.These descriptions It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed And change.The purpose of selecting and describing the exemplary embodiment is that explain that the certain principles of the present invention and its reality should With so that those skilled in the art can realize and utilize the present invention a variety of exemplaries and Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
