Abstract
The invention discloses an energy-absorption air bag used for an automobile bumper. The energy-absorption air bag comprises an air bag body installed on the front side of the automobile bumper and damping air holes formed in the sides of the air bag body, and stepped wrinkles are arranged on the upper portion and the lower portion of the air bag body. When the energy-absorption air bag has collision, the accelerated speed in collision is decreased due to small rigidness and good buffering-deformation capacity, and the safety of passengers, passersby and automobiles is improved.
Description
Technical field
The present invention relates to automotive safety facility, particularly a kind of energy-absorbing air bag for nerf bar.
Background technology
In the front portion of automobile, be generally provided with the bumper/spoiler that automobile is shielded, when automobile collides, stopped by safety lever, thus make automobile avoid being knocked.But, after bumper/spoiler collides, be easier to bending or fracture, cause bumper/spoiler cannot protect automobile.The material rigidity of bumper/spoiler is higher, can produce larger acceleration/accel when colliding, and is unfavorable for occupant and vehicle body safety.In addition, when more due to its larger rigidity and less deformation, pedestrian being made to bear great impact force, causing serious consequence with during pedestrian collision.
Also occurred the measure protected bumper/spoiler in recent years, in bumper/spoiler installed in front foam energy absorbent block, but foam is easier to when clashing into damage, and buffering effect is poor.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of energy-absorbing air bag for Federal bumper, thus overcome the shortcoming using foam energy absorbent block to be easier to damage when clashing into.
For achieving the above object, the invention provides a kind of energy-absorbing air bag for Federal bumper, comprising: airbag body, it is installed on the front side of Federal bumper, and the top and the bottom of this airbag body are provided with stair-stepping fold; And damping pore, it is located at the sidepiece of described airbag body.
Preferably, described airbag body is curved.
Preferably, the radian of described arc is 10-35 °.
Preferably, the inside of described airbag body is made up of multiple little air chamber communicated.
Preferably, described airbag body is fixed on the front side of described Federal bumper by mount pin.
Preferably, described damping pore is two, is located at the both sides of described airbag body respectively.
Compared with prior art, the present invention has following beneficial effect:
1. the energy-absorbing air bag in the present invention; after the compression that is collided; airbag body is compressed; the portion gas in airbag body is discharged by damping pore; play good buffering deformability to protect nerf bar, and the elasticity of the stepped fold of airbag body can be relied on to return to the original form.
2. energy-absorbing air bag is owing to adopting air as compressed media, has good buffering effect.
3. collision energy can be converted into gas internal energy and discharge airbag body by damping pore, is dissipated in surrounding environment.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole specification sheets and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or component part, and do not get rid of other element or other component part.
As shown in Figures 1 to 4, according to a kind of energy-absorbing air bag for Federal bumper of the specific embodiment of the invention, comprise: airbag body 2 and damping pore 3, airbag body 2 employing has certain thickness elastic caoutchouc and makes, its inside is air cavity, be full of air, more specifically, the inside of airbag body 2 is made up of multiple little air chamber communicated, multiple little air chamber also can play when airbag body 2 is compressed, to the effect that compressed air stream cushions, airbag body 2 is fixed on the front side of Federal bumper by mount pin 1, better fit with the front side of Federal bumper to make this airbag body 2, airbag body is established curved, the radian of arc is 10-35 °, be convenient to make full use of finite space around bumper/spoiler.As shown in Figure 4, being provided with stair-stepping fold 4 in the top and the bottom of airbag body 2, making airbag body 2 be easier to when there is compression restore to the original state; Damping pore 3 is located at the sidepiece of airbag body 2, for can better be vented, is equipped with damping pore 3 at the end face of the both sides of airbag body 2.Damping pore 3 is through test in advance and calculating, the gas that its size can ensure to get rid of in time when collision dynamics acquires a certain degree reasonable amount makes the pressure inside the air bag that is extruded be unlikely to excessive, rigidity increase is unlikely to excessive, then plays the effect controlling collision dynamics.
During use; when colliding especially with pedestrian collision; airbag body is compressed; when rigidity increases to a certain degree; by the exhaust of damping pore, air bag rigidity and collision dynamics can be controlled preferably, reduce the acceleration/accel of collision; the effect of protection pedestrian, occupant can be played, improve the safety of automobile.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
