The specific embodiment
According to accompanying drawing, provide the preferred embodiment of the utility model, and describe in detail below, enable to understand better function, the characteristics of the utility model.
Fig. 3-Fig. 5 illustrates the fixedly additional strengthening according to the automotive airbag of a preferred aspect of the utility model structure.As shown in Figure 3; The fixedly additional strengthening of this automotive airbag; Comprise air bag reinforced bulkhead 8, air bag doors 9 and air bag hinge 10; This three is through the moulding of inserts integrated through injection molding, and wherein, the structure of air bag reinforced bulkhead 8 and air bag doors 9 is identical substantially with the structure of air bag reinforced bulkhead 1 of the prior art and air bag doors 2 (referring to accompanying drawing 1); Its difference is that air bag reinforced bulkhead 8 and air bag doors 9 all adopt the polypropylene material of filled toughening to process; Such as PP-EPDM-T20 (that is: the polypropylene that ethylene propylene diene rubber is toughness reinforcing, 20% breeze is filled), PP-EPDM-T25 (that is: the polypropylene that ethylene propylene diene rubber is toughness reinforcing, 25% breeze is filled), PP-EMDM-T15 (that is: the polypropylene that ethylene propylene diene rubber is toughness reinforcing, 15% breeze is filled) etc., to compare with the TPO material, the material price of PP-EPDM-TXX series is much lower; Generally at 40 yuan/kilogram, and PP-EPDM-T20 has only 10 yuan/kilogram such as TPO.Fixedly additional strengthening difference with the prior art according to the automotive airbag of the utility model is that also air bag hinge 10 is employed in the high strength material that all has better performance under the high low temperature condition and processes; Such as metal; Because metal is all very stable under high temperature and low temperature condition; Easy fracture can not satisfy the requirement of air bag hinge to strength of material.
As shown in Figure 4, on the sidewall 81 of air bag reinforced bulkhead 8, be symmetrically arranged with some square holes 12; Be used to cooperate the hook 17 (referring to accompanying drawing 5) on the air bag module 16 of coupling type air bag; Hook is 17 consistent with square hole 12 numbers, and the position correspondence is hung among the square hole 12 so that will link up with 17 when assembling.Also be provided with the oblique angle 14 that when the rotation assembling of air bag module 16 (referring to accompanying drawing 5), play the guiding role on the sidewall 81 of air bag reinforced bulkhead 8.On sidewall 81 exterior four angles of air bag reinforced bulkhead 8, be symmetrically arranged with four screw point of connection 15, be used for air bag module 16 and be connected with the screw of air bag reinforced bulkhead 8.In a preferred embodiment of the utility model, on the sidewall 81 of this air bag reinforced bulkhead 8, also be provided with the groove 13 of at least one half opening, its opening direction is away from air bag doors 9, and is as shown in Figure 4.The width of the opening of this groove 13 can be adjusted as required, as long as satisfy the deformation requirements of the sidewall 81 of air bag reinforced bulkhead 8.In addition, the spacing distance that is provided with between position, number and each groove of this groove 13 can be adjusted equally as required.
As shown in Figure 5, air bag hinge 10 comprises a part 101 that is embedded in the air bag doors 9 and is embedded in the another part 102 in the air bag reinforced bulkhead 8 that these two parts link to each other through bending part 103.This air bag hinge 10 through bending part 103 behind the bending certain angle with air bag doors 9 and the 8 one inserts injection mouldings of air bag reinforced bulkhead, can prevent that air bag doors 9 and air bag hinge 10 from separating with air bag reinforced bulkhead 8.A part 101 inserts of air bag hinge 10 are in the extension plane of air bag doors 9, and another part 102 inserts and extend to around the square hole 12 in the sidewall 81 of air bag reinforced bulkhead 8, match with hook 17 on the air bag module 16.During the air bag explosion; Air bag hinge 10 relative air bag reinforced bulkhead 8 separative trend; Because polypropylene material is the meeting deliquescing under the hot environment that explosion produces; And air bag hinge 10 will produce the application force of pullling each other with air bag hook 17, preventing that air bag doors 9 with air bag hinge 10 and air bag reinforced bulkhead 8 relative displacemenies takes place in the blasting process, even separates and comes off.In addition, air bag hinge 10 be embedded in the said air bag doors a part 101 be embedded on the another part 102 in the said air bag reinforced bulkhead, be provided with some groups of hangnails 11, to guarantee the connectivity robustness between inserts metal and the plastics.
Fig. 6 shows the fixedly additional strengthening according to the automotive airbag of another preferred aspect structure of the utility model.The fixedly additional strengthening of this automotive airbag; Comprise air bag reinforced bulkhead 8; Two air bag doors 9 and two and air bag doors 9 be air bag hinge 10 one to one; Wherein each air bag hinge 10 comprises a part 101 that is embedded in the cooresponding with it air bag doors 9 and is embedded in the another part 102 in the air bag reinforced bulkhead 8, and these two parts link to each other through bending part 103.Other each block construction, material and the action principle all fixedly additional strengthening with automotive airbag shown in Figure 5 are identical substantially.
In an embodiment of the utility model, the polypropylene material of filled toughening is to adopt breeze to fill, and carries out toughness reinforcing through thermoplastic elastomer or polyolefin elastic body or acetate ethylene copolymer or EP rubbers.
In another embodiment of the utility model, the number at the oblique angle 14 on the air bag reinforced bulkhead 8 can be adjusted according to actual needs.
In another embodiment of the utility model, the number of the screw point 15 on the air bag reinforced bulkhead 8 can be adjusted according to actual needs.
In another embodiment of the utility model, the sidewall thickness of air bag reinforced bulkhead 8 can be adjusted according to actual needs.
In another embodiment of the utility model, the inserts area of the air bag hinge 10 in the air bag doors 9 can be adjusted according to actual needs.
The utility model is preferred for being connected of coupling type air bag and automotive trim, and in addition, the air bag of non-coupling type also is suitable for this structure.
Above-described, be merely the preferred embodiment of the utility model, be not scope in order to qualification the utility model, the foregoing description of the utility model can also be made various variations.Be that every simple, equivalence of doing according to the claims and the description of the utility model application changes and modification, all fall into the claim protection domain of the utility model patent.The utility model not detailed description be the routine techniques content.
