Description
Technical field
The utility model relates to a kind of connection structure that is used for being installed in the bearing circle and the air bag module of power actuated vehicle.
Background technology
All be equipped with air bag module at present in most motor vehicle steering wheels, this air bag module is installed in the bearing circle as independent structural unit and comprises multiple independent structures element and multiple function.The radical function of such air bag module is, the air bag that is filled with gas is provided between chaufeur and bearing circle during collision.
For this reason, air bag module comprises parts such as airbag and housing, and airbag is installed on the housing, and housing is installed on the bearing circle, thereby reaches the assembling of air bag module and bearing circle.More common air bag and bearing circle fit has two kinds at present, a kind of is by with at least two bolts housing being connected on the bearing circle, thereby with air bag module 1 and bearing circle 2 (see figure 1) that tightens together, the advantage of this fit is that assembling is firm, shortcoming is that assembling is inconvenient, is easy to generate noise between the metal assembling joint face; And another is by the hook structure on air bag module 1 and the bearing circle 2, finish the assembling (see figure 2) by mutual clamping, the advantage of this fit is easy to assembly, and that to be the hook matrix put the energy that bears when quick-fried at air bag to shortcoming is higher so the design of hook and matrix is had requirements at the higher level.
In addition, safety air bag can produce very at point that macro-energy acts on hook and the matrix thereof in the quick-fried process, makes hook easily and matrix cracks, is out of shape and failure mode such as fracture.
The purpose of this utility model is to improve the energy management of air bag module hook structure in the quick-fried process of point, avoids the potential failure form, thereby guarantees the protective value to the occupant.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of connection structure that is used for being installed in the bearing circle and the air bag module of power actuated vehicle; improving the potential failure that air bag module exists in the quick-fried process of point, thereby guarantee protective value to the occupant.One energy management structures is set on this connection structure, when air bag is put when quick-fried, can absorb the quick-fried energy that produces of air bag point, to reduce Joint strenght required between this connection structure and the air bag component, and then the manufacturing cost of reduction air bag component, make and adopt lower metal or the plastics of intensity to become possibility as matrix; Simultaneously, alleviate impact, guarantee that correlated parts does not crack in the product life cycle, excessive deformation or fracture hook and matrix thereof.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of connection structure that is used for being installed in the bearing circle and the air bag module of power actuated vehicle, comprise that one embeds the transom in the airbag housing of air bag module, this transom is connected with grab on the bearing circle, it is characterized in that described transom is provided with an energy management structures.
Because the utility model transom has been provided with energy management structures, thereby the airbag housing that can make air bag module adopts plastics to make with cost-cutting and raising manufacturing efficient, and connection structure is embedded in the airbag housing in the process of airbag housing injection mo(u)lding, be used for and being connected of bearing circle.And when concrete assembling, only need connection structure on the airbag housing and the grab on the bearing circle are assembled, be convenient to very much install and be connected firmly with bearing circle; Energy management structures on the connection structure helps air bag module to absorb part energy when point is quick-fried, makes air bag module keep structure integrity.
In a preferred exemplary of the present utility model, connection structure adopts a hook form, so that assemble with grab on the bearing circle, improves installation effectiveness and is connected with the firm of bearing circle.Such hook is embedded in the airbag housing in the process of airbag housing injection mo(u)lding.For hook can be embedded in the airbag housing securely, meander-shaped is arranged at the two ends of hook, and this meander-shaped forms a focusing surface, and this focusing surface should be put when quick-fried at air bag with hook, suffered direction of pull shape at an angle, preferably and direction of pull perpendicular.
In order to improve the traveling comfort of driving, clash into the noise that is sent between the grab of hook and bearing circle in the minimizing air bag module vibration processes, the utility model can scribble muffle coating with the grab connecting portion of bearing circle on hook, by the buffering of this muffle coating, can eliminate effectively between the hook and the grab of bearing circle and clash into the noise that is sent.
The utlity model has following advantage:
1) air bag is put in the quick-fried process and can be absorbed part energy, guarantees that correlated parts does not crack, excessive deformation or fracture, also makes and adopts lower metal or the plastics of intensity to become possibility as matrix;
2) part is few, and is in light weight, and cost reduces;
3) hook lower end coating helps to slow down noise.
