Abstract
The utility model relates to a damping device of a gas generator arranged on a steering wheel. The damping device comprises a supporting plate and a buffer assembly. The gas generator is connected onto the buffer assembly made of rubber, when a car has head-on collision, the buffer assembly made of rubber and arranged in a supplementary restraint system module can effectively buffer recoil force generated when the gas generator is exploded, and therefore contact time of an air bag and a person is prolonged, buffer time of a safety belt is prolonged, inertial impact on the person is reduced to a certain extent, impact generated when the person and the air bag collide is reduced, and the injury degree of the person is reduced. In addition, the gas generator is connected onto an elastic connection column of the buffer assembly and has a certain shaking capability so that when bumping and shaking which are generated in the whole car driving process are transmitted to the steering wheel, the steering wheel can gather the energy through the buffer assembly to transmit the energy to the gas generator, the gas generator and the elastic connection column shake, the shaking degree of the steering wheel is reduced, noise is reduced, and driving comfortableness is improved. The damping device belongs to the technical field of automobile accessories.
Description
Technical field
The utility model belongs to the automobile fitting technical field, especially relates to gas generator shock absorption device on a kind of bearing circle.
Background technology
As everyone knows, gas generator is installed in the air bag system module on the vehicle steering of belonging in the vehicle steering, and safety air bag can play buffer action when collision happens, thereby reduces the injury that bump causes chaufeur in the car.Along with building energetically and raising that automobile is controlled performance of express highway, the moving velocity of automobile is more and more faster, particularly because the increasing sharply of car owning amount, traffic is more and more crowded, make accident more frequent, when reducing automobile generation head-on crash since huge force of inertia cause to the chaufeur injury, automobile generally is equipped with air bag system in chaufeur front end bearing circle central authorities.
Air bag module in the existing bearing circle mainly is made up of air bag, gas generator and firing unit, gas generator directly is fixed on the air-bag support with special bolt is fixing, air-bag support is fixed in the bearing circle, the three belongs to and is rigidly connected, there is certain influence in vibration and noise reducing in the normal vehicle operation, can't reduces the bearing circle shake; In addition, when traffic accident takes place, can't alleviate air-cushion inflator and put the tool big bounce power of bringing when quick-fried, vehicle is affected and damages.
The utility model content
Technical problem to be solved in the utility model is: gas generator shock absorption device on a kind of bearing circle that possesses favorable damping, noise reduction, cushion characteristic is provided.
Technical solution adopted in the utility model is: gas generator shock absorption device on a kind of bearing circle is used for being connected the Buffer Unit of gas generator on comprising supporting disk and being fixed on supporting disk.
Described Buffer Unit comprise base plate with a plurality of be used to the elastic fixing pole that is connected gas generator.
Described elastic fixing pole is provided with the annular slot of being convenient to the gas generator clamping.
Described elastic fixing pole top is provided with the guidepost of the connecting bore insertion of being convenient on the gas generator.
Described Buffer Unit also includes avoids the blend stop that rocks significantly about gas generator.
Described blend stop is the elasticity blend stop.
Described Buffer Unit also includes for the annular brace pad that supports gas generator, and described annular brace pad is positioned at the ring of encirclement that blend stop forms.
Base plate on the described Buffer Unit, elastic fixing pole, blend stop and annular brace pad are formed in one.
Described Buffer Unit is that elastomeric material is made.
Described Buffer Unit is that silaatic is made.
The beneficial effects of the utility model are: gas generator shock absorption device on the utility model bearing circle, be used for connecting gas generator and bearing circle, gas generator is connected on the Buffer Unit of rubber material, when automobile generation head-on crash, the Buffer Unit of the rubber material in the air bag module can the efficient buffer gas generator be put the recoil that produces when quick-fried, be equivalent to prolong air bag and personnel's contact time, prolong the surge time of safety strap, reduced personnel's inertia impact to a certain extent, impact when reduction personnel and air bag bump reduces injured degree.In addition, because gas generator is connected on the elastic fixing pole of Buffer Unit, has certain rolling kinetic force, when the shock transfer of jolting that produces in vehicle complete vehicle travels is given bearing circle, bearing circle just can be reunited energy by Buffer Unit and be passed to gas generator, makes gas generator and elastic fixing pole shake, and reduces the degree of jitter of bearing circle, reduce noise, improve driver comfort.
Description of drawings
Fig. 1 is the utility model scheme drawing.
Among the figure, 1, supporting disk, 2, base plate, 3, elastic fixing pole, 3.1, annular slot, 3.2, guidepost, 4, blend stop, 5, the annular brace pad.
The specific embodiment
Below be the utility model preferred embodiment, but therefore do not limit protection domain of the present utility model.
With reference to shown in Figure 1, gas generator shock absorption device on a kind of bearing circle of the utility model, on comprising supporting disk 1 and being fixed on supporting disk 1 for the Buffer Unit that is connected gas generator.
Described Buffer Unit comprise base plate 2 with a plurality of be used to the elastic fixing pole 3 that is connected gas generator.Elastic fixing pole 3 can double swerve, be conducive to like this reunion of the shake energy on the bearing circle is come, transfer on elastic fixing pole 3 and the gas generator, allow the two shake, because described both are closed in the bearing circle, even therefore the two shake, chaufeur also be can't see, and does not influence vision.
Described elastic fixing pole 3 is provided with the annular slot of being convenient to the gas generator clamping 3.1.Snap fit is simple, and is easy for installation, and fastness is good.
Described elastic fixing pole 3 tops are provided with the guidepost 3.2 of the connecting bore insertion of being convenient on the gas generator, make things convenient for the connecting bore insertion guidepost 3.2 of gas generator and the annular slot 3.1 on the elastic fixing pole 3 to match, and improve efficiency of assembling.
Described Buffer Unit also includes avoids the blend stop 4 that rocks significantly about gas generator, improves the product compactedness.
Described blend stop 4 is the elasticity blend stop, has buffer action, and curved.
Described Buffer Unit also includes for the annular brace pad 5 that supports gas generator, and described annular brace pad 5 is positioned at the ring of encirclement that blend stop 4 forms.
Described Buffer Unit is that elastomeric material is made.
Described Buffer Unit is that silaatic is made, tear strength and high temperature fatigue performance excellence, properties of product good stability.The utility model is formed by supporting disk and the silicon rubber vulcanization of metal.
