Description
Technical field
The utility model relates to new-energy automobile part field, specifically a kind of new-energy automobile energy-storage system collision is anti-
Protect airbag apparatus.
Background technique
Energy-storage system is the important component of new-energy automobile, and more serious safety accident is occurring for new-energy automobile
After the collision between vehicle such as occurs, the extruding between its energy-storage system and other components easily occurs, puncture etc., so as to cause
Short circuit is occurred by the energy-storage system collided, leakage, it is on fire more seriously to cause energy-storage system, and explosion etc., this is to occupant
Life security cause to seriously threaten.
According to statistics, in the collision safety accident that vehicle occurs, the accident that head-on crash occurs is in the great majority, and is secondly side
Face collision accident.When head-on crash occurs for vehicle, enough collision deformation energy-absorbings region, energy-storage system are possessed by front part of vehicle
The probability being squeezed and deformed is lower.Therefore, compared to head-on crash accident, when the side between vehicle occurs for new-energy automobile
When collision, since the both ends of energy-storage system are close to the threshold of vehicle, side collision impact causes threshold that biggish deformation occurs, stays
It is smaller to the buffering energy-absorbing region of energy-storage system.In addition, the front energy-absorbing region such as bumper of impact vehicle is invaded and is collided
A possibility that bottom, is larger, causes to seriously threaten to by the energy-storage system collided.Therefore, it is necessary to the storage to new-energy automobile
The crashworthiness of energy system causes enough attention.It is whole that the protection of existing new-energy automobile energy-storage system relies primarily on automobile
The crash-worthiness of bassinet structure, this may result in research staff and excessively pays close attention to the design of energy-storage system peripheral parts crash-worthiness, causes to touch
It hits that section components rigidity is excessive, leads to that the Rigidity Matching of vehicle is unreasonable, collision vehicle acceleration is excessive.
Utility model content
The utility model in order to solve problems in the prior art, provides a kind of new-energy automobile energy-storage system collision protection
Airbag apparatus can effectively prevent intrusion of the deformation component to energy-storage system, meanwhile, air bag has small in size, stability
Well, the advantages that high reliablity, light weight.
The utility model includes driving circuit, the integrated safety airbag module of gas generator and airbag composition, air bag
Shield and mounting bracket, wherein airbag restraint cover is separately mounted to energy-storage system both sides, air bag mould by mounting bracket
Block is arranged on the inside of airbag restraint cover, and gas generator is stored with the electronic control list of control circuit by driving circuit and one
First (ECU) connection, electronic control unit (ECU) input terminal are connected with side impact sensor.
Utility model works mode is as follows: side impact sensor induction acceleration collision alarm, then believes collision
Number pass to electronic control unit (ECU).ECU believes by comparing its internal acceleration signal threshold value and side impact sensor
Number acceleration value, then determine whether to ignite by ECU analytical calculation, if it is determined that ignition signal is sent storage by detonation
Can system airbag cushions module, gas generator is inflated in module, and airbag will be filled in a very short period of time, is energy storage
System provides protection.
The utility model beneficial effect is:
Under side collision operating condition, the energy absorbing component of automobile is few, and license energy-absorbing deformation distance is short, and existing new energy vapour
The side collision protection of vehicle energy-storage system relies primarily on the threshold of automobile, and the isostructural deformation of B column absorbs collision impact energy.This
Utility model novelty is in the collision safety protection by airbag applications to new-energy automobile energy-storage system.When generation vehicle
Side collision when, energy-storage system air bag is inflated in a very short period of time, in the deformation component of energy-storage system and vehicle
Between formed an energy-absorbing buffering region, can effectively prevent intrusion of the deformation component to energy-storage system, such as: squeeze, puncture etc..
Meanwhile air bag has the advantages that small in size, stability is good, high reliablity, light weight.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model
Fig. 2 is utility model works schematic diagram.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
The utility model structure is as shown in Figure 1, include driving circuit, the monoblock type safety of gas generator and airbag composition
Air bag module, airbag restraint cover and mounting bracket, wherein airbag restraint cover is separately mounted to energy-storage system two by mounting bracket
Side, air bag module are arranged on the inside of airbag restraint cover, and gas generator is stored with control electricity by driving circuit and one
The electronic control unit (ECU) on road connects, and electronic control unit (ECU) input terminal is connected with side impact sensor.
Utility model works mode will then touch as shown in Fig. 2, side impact sensor induction acceleration collision alarm
It hits signal and passes to electronic control unit (ECU).ECU is sensed by comparing its internal acceleration signal threshold value and side collision
Then the acceleration value of device signal determines whether to ignite by ECU analytical calculation, if it is determined that detonation sends ignition signal
To energy-storage system air bag module, gas generator is inflated in module, and airbag will be filled in a very short period of time, be
Energy-storage system provides protection.
There are many utility model concrete application approach, and the above is only the preferred embodiment of the utility model, should
It points out, for those skilled in the art, without departing from the principle of this utility model, can also make
Several improvement out, these improvement also should be regarded as the protection scope of the utility model.
