Abstract
The present invention relates to a kind of energy-absorbing air bags for protecting battery box for electric passenger car; include for mounted on battery case side airbag body, be set to airbag body side damping stomata and the mounting pin that is set to the airbag body back side; airbag body is formed by multiple cuboid-type air bag stacked combinations; multiple air bags are gradually reduced stepped from airbag body back-to-front, and multiple gas chambers communicated are divided into inside airbag body.Compared with prior art, energy-absorbing air bag of the invention is when colliding, and due to its smaller rigidity, good buffering deformability can reduce the acceleration of collision, improve the safety of battery case, electric motor coach.
Description
Technical field
The present invention relates to field of automobile safety, more particularly to a kind of energy-absorbing air bags for protecting battery box for electric passenger car.
Background technology
Lower part is leaned in the side that the battery case of electric motor coach is typically mounted at car, in the installation position of battery case, generally all
Equipped with the bumper to shield to battery case.When the side of car is by hitting, stopped by bumper, to make
Battery case avoids being knocked.But after bumper is collided, it is easier to be bent or is broken, cause bumper can not be to battery
Case is protected.The material rigidity of bumper is higher, by will produce larger acceleration when colliding, if bumper occurs to break
It splits and the battery in battery case is damaged, due to the special chemical property of battery, battery may be caused to occur on fire, explosion
Equal major accidents, crisis passenger and pedestrains safety.
Invention content
It is electronic for protecting that it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind
The energy-absorbing air bag of car battery case.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of energy-absorbing air bag for protecting battery box for electric passenger car, including:
Airbag body, for being mounted on battery case side,
Stomata is damped, airbag body side is set to,
Mounting pin is set to the airbag body back side.
Preferably, the airbag body is formed by multiple cuboid-type air bag stacked combinations, and multiple air bags are from air bag sheet
Body back-to-front is gradually reduced stepped.
Preferably, the airbag body is formed by three cuboid-type air bag stacked combinations.
Airbag body may be used to be made with certain thickness elastic rubber, and inside is air cavity, is full of air.It is special to set
The step structure of meter, when stepped stacked especially with three cuboid-type air bags so that airbag body is being pressed
It is easier to restore to the original state when contracting.
Preferably, multiple gas chambers communicated are separated into inside the airbag body.
By will be separated into the small gas chamber communicated inside airbag body, multiple small gas chambers, which are advantageous in that play, works as air bag
When ontology is compressed, better cushioning effect is carried out to compressed air stream.
Preferably, airbag body marginal surface sets arc-shaped chamfering shape.
Preferably, there are two the damping stomata is set, two sides of airbag body are located at.
It is a kind of with the air vent centainly damped to damp stomata, when airbag body internal pressure (is touched more than a certain numerical value
Hit and be under pressure) when, the gas inside airbag body can be discharged, can usually keep inside air bag pressure, process both can be with
It is realized, can also be realized by mechanical structure by means of pressure sensor.Stomata is damped by test in advance and is calculated, it is big
The small gas that can ensure that reasonable amount is discharged in time when collision dynamics reaches a certain level so that inside the air bag being extruded
Pressure is unlikely to excessive, and rigidity increase is unlikely to excessive, then plays the effect of control collision dynamics.In use, when touching
When hitting that especially battery case is by colliding, airbag body is compressed, and when rigidity is increased to a certain extent, passes through the row for damping stomata
Gas can preferably control air bag rigidity and collision dynamics, reduce the acceleration of collision, can play protection battery case, protection
The effect of passenger improves the safety of electric motor coach.
Damping stomata is set to two sides of airbag body, can be preferably vented in collision process.
Compared with prior art, the invention has the advantages that:
(1) the energy-absorbing air bag in the present invention uses air as compressed media, has good buffering effect, overcomes insurance
Thick stick may deform when by colliding fracture the shortcomings that, and in bumper by after deforming when hitting, energy-absorbing gas
Capsule can further protect battery case.
(2) the energy-absorbing air bag in the present invention, after the compression that is collided, airbag body is compressed, by damping stomata row
Go out the portion gas in pneumatophore, plays good buffering deformability to protect battery case.
(3) damping stomata can convert collision energy to gas internal energy discharge airbag body, be dissipated in ambient enviroment.

Fig. 1 is the structural diagram of the present invention;
Fig. 2 is the main structure diagram of the present invention;
Fig. 3 is the left view structural representation of the present invention;
Fig. 4 is the overlooking structure diagram of the present invention.
In figure, 1 is airbag body, and 2 be damping stomata, and 3 be mounting pin.
Specific implementation mode
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
A kind of energy-absorbing air bag for protecting battery box for electric passenger car, as shown in figures 1-4, including airbag body 1, damping
Stomata 2 and mounting pin 3.Airbag body 1 (is three in the present embodiment by multilayer using having certain thickness elastic rubber to be made
Layer) cuboid-type air bag composition of different sizes, internal is air cavity, is full of air, 1 marginal surface of airbag body sets arc-shaped
Chamfering shape.More specifically, the inside of airbag body 1 is made of multiple gas chambers communicated, and multiple gas chambers, which are advantageous in that, may be used also
Play the role of when airbag body 1 is compressed, to compressed air stream into row buffering.Airbag body is fixed on electricity by mounting pin 3
The side of pond case, airbag body is designed to step structure, and (multiple cuboid-type air bags of different sizes are from the airbag body back side
It is in diminishing arranged in step shape to front) so that airbag body 1 is easier to restore to the original state when compressing;Damp gas
Hole 2 is set to the side of airbag body 1, and can be preferably vented, damping stomata is equipped in the end face of the both sides of airbag body 1
2.Stomata 2 is damped by test in advance and is calculated, size can ensure to be discharged in time when collision dynamics reaches a certain level
The gas of reasonable amount so that the pressure inside air bag being extruded is unlikely to excessive, and rigidity increase is unlikely to excessive, then plays
Control the effect of collision dynamics.
In use, airbag body 1 is fixed on by battery case side by the mounting pin 3 for being set to the airbag body back side, when
When colliding that especially battery case is by colliding, airbag body 1 is compressed, and when rigidity is increased to a certain extent, passes through damping
The exhaust of stomata 2 can preferably control air bag rigidity and collision dynamics, reduce the acceleration of collision, can play protection electricity
Pond case, the effect for protecting passenger, improve the safety of electric motor coach.
The above-mentioned description to embodiment is for ease of ordinary skill in the art to understand and use the invention.It is ripe
The personnel for knowing art technology obviously easily can make various modifications to these embodiments, and general original described herein
It ought to use in other embodiment without having to go through creative labor.Therefore, the present invention is not limited to the above embodiments, this field
