Detailed description of the invention
Now by reference to the accompanying drawings the utility model is described further.
Embodiment 1
See Fig. 1 ~ Fig. 2, in this example, the flange portion of air bag module 1 is connected with instrument carrier panel plastic components, the bottom of air bag module 1 is connected with adopting installation bracket 2 between dashboard cross member, installation bracket 2 comprises support portion 21, installation portion 22 and buffering connecting portion 23, support portion 21 is connected and fixed by mounting hole 211 and air bag module 1, and installation portion 22 is connected and fixed with dashboard cross member by another mounting hole 221, and buffering connecting portion 23 connects support portion 21 and installation portion 22.
The integral structure that support portion 21, installation portion 22 and buffering connecting portion 23 are manufactured by identical material, particularly make close to material with plastics or characteristic and plastics, be warp architecture in the middle of buffering connecting portion 23, the thickness of buffering connecting portion 23 is less than the thickness of support portion 21 and installation portion 22.Because the buffering shape of the connecting portion 23 and impact of thickness, the rigidity of buffering connecting portion 23 is lower than the rigidity of support portion 21 and installation portion 22.
When transmitting to air bag module 1 direction from body vibrations through dashboard cross member, installation bracket 2, particularly cushions connecting portion 23 and can absorb and block transmission of vibration, reduce air bag module 1 and instrument carrier panel and vehicle body and produce the risk resonated.
Embodiment 2
See Fig. 3, this example is on the basis of embodiment 1, the warp architecture of buffering connecting portion 23 sets up several peristomes 231, buffering connecting portion 23 rigidity being provided with peristome 231 is lower, can the effect absorbing and block vibration passing be improved, reduce air bag module 1 and instrument carrier panel and vehicle body better and produce the risk resonated.
Embodiment 3
See Fig. 4, the difference of this example and embodiment 1 is: cushion connecting portion 23 and be provided with several and weaken groove 232, the thickness of the buffering connecting portion 23 that reduction groove 232 place is corresponding is less than the thickness of adjacent regions.Thus, the entirety of buffering connecting portion 23 has very low rigidity, can absorb and block transmission of vibration, reduces air bag module 1 and instrument carrier panel and vehicle body and produces the risk resonated.
Embodiment 4
See Fig. 5 ~ Fig. 7, in this example, the flange portion of air bag module 1 is connected with instrument carrier panel plastic components, the bottom of air bag module 1 is connected with adopting installation bracket 2 between dashboard cross member, installation bracket 2 comprises support portion 21, installation portion 22 and buffering connecting portion 23, support portion 21, installation portion 22 and buffering connecting portion 23 are split-type structural, support portion 21 and air bag module 1 are connected and fixed, installation portion 22 and dashboard cross member are connected and fixed, buffering connecting portion 23 is flexible joint, and flexible joint connects support portion 21 and installation portion 22.
Support portion 21 is provided with near one end of flexible joint and supports notch part 212, and installation portion 22 is provided with installation gap portion 222 near one end of flexible joint.The connection support portion, one end 21 of flexible joint, and some flexible material embeds in support notch part 212, thus be connected firmly with support portion 21.The other end connection portion 22 of flexible joint, and some flexible material embeds in installation gap portion 222, thus be connected firmly with installation portion 22.After connection, support portion 21, installation portion 22 and flexible joint form a global facility, i.e. installation bracket 2.
Because support portion 21 and installation portion 22 itself are relatively independent, when the body vibrations transmitted from dashboard cross member upwards transmits through installation portion 22, flexible joint can cushion and absorb vibration, the vibration being passed to support portion 21 and air bag module 1 and instrument carrier panel plastic components is reduced greatly, reduces air bag module 1 and instrument carrier panel and vehicle body and produce the risk resonated.
