Specific implementation mode
The utility model is described further in conjunction with attached drawing.
Referring to Fig. 1, a kind of steering wheel and driver airbag assembly apparatus, including driver airbag, steering wheel,
Steel wire, conducting boss, mounting pin and fixed steel wire is connected, the bottom of 2 shell of driver airbag is equipped with conducting 21 He of steel wire
Mounting pin 22, the intermediate former of steering wheel 1 are equipped with several conducting boss 11, conducting steel wire 21 be connected boss 11 contact or
It detaches, clamping portion is equipped on the inside of the end of mounting pin 22, supporting surface is equipped on the outside of the end of mounting pin 22, fixes the interior of steel wire 3
Side straight flange 32 and the clamping portion of mounting pin 22 are clamped, and the outside straight flange 31 of fixed steel wire 3 is supported on the supporting surface of mounting pin 22,
The position of inside straight flange 32 is higher than the position of outside straight flange 31.In this example, fixed steel wire 3 is U-shaped, and clamping portion is card slot 221, branch
Support face is inclined-plane 222.
When driver does not press loudspeaker aloud, driver airbag 2 is under the support of fixed steel wire 3 and steering wheel 1, place
In design predetermined state, at this point, there are gaps, vehicle horn circuit to be not turned between conducting steel wire 21 and conducting boss 11, loudspeaker
Do not ring.
When driver needs to press loudspeaker aloud, driver airbag 2 can be pressed down on, at this point, conducting steel wire 21 is accompanied the emperor
The person's of sailing air bag 2 moves downwardly together, and to be contacted with conducting boss 11, vehicle horn circuit conducting, loudspeaker sound.
When driver cancels the power of pressing driver airbag 2, work of the driver airbag 2 in fixed steel wire 3
It firmly floats up down, 2 restoration designing predetermined state of driver airbag, at this point, steel wire 21 is connected and presses conducting boss aloud
There are gap, restoration designing predetermined states between 11.
As the conventional design at present using helical spring, main distinction point mainly exists utility model works process
It is different in the source for the power that driver airbag 2 floats up.
Referring to Fig. 2, Fig. 3 and Fig. 4, fixed steel wire 3 is fixed using hook 12, and the surrounding in mounting pin 22 is arranged in hook 12,
Fixed steel wire 3 is stuck on hook 12.On steering wheel 1,22 surrounding of each mounting pin be arranged four hooks 12, this four hooks 12 at
Two rows are evenly distributed on around mounting pin 22.Respectively one row's hook 12 of setting, fixed steel wire 3 wrap in the outside and inside of mounting pin 22
Inside straight flange 32 and outside straight flange 31 are included, outside straight flange 31 is stuck on two hooks 12 in 22 outside of mounting pin, inside straight flange 32
It is stuck on two hooks 12 of 22 inside of mounting pin.
Referring to Fig. 5 and Fig. 6, in order to realize the function of pressing aloud of driver airbag 2, i.e., when driver does not press loudspeaker aloud
It is presetting in stable condition, situations such as shaking up and down, shake and position offset do not occur, while pressing loudspeaker aloud in driver
, mounting pin 22 on driver airbag 2 can realize the function of pressing aloud after stroke in pressing aloud for setting, mounting pin 22 by
Two important structure features compositions, one be outside inclined-plane 222, one be inside card slot 221.Outside fixed steel wire 3
Side straight flange 31 is withstood the inclined-plane 222 of mounting pin 22 by the position constraint of the hook 12 in 22 outside of mounting pin, ensures driver safety
Air bag 2 will not move downward when not pressing aloud, while 32 upper surface of inside straight flange of fixed steel wire 3 is touched by the hook 12 of inside,
Lower surface is touched by the lower surface of card slot 221 so that will not have upward movement when driver airbag 2 is not pressed aloud, therefore
State when driver airbag 2 is not pressed aloud is set.
When pressing driver airbag 2, mounting pin 22 moves downward, and the inside straight flange 32 of fixed steel wire 3 is by hook
12 fix, and the inclined-plane 222 of mounting pin moves downward, and the outside straight flange 31 of fixed steel wire 3 is driven to move horizontally, and realize driver's peace
Full air bag 2 presses motor function aloud.The movement clearance of fixed 3 inside straight flange 32 of steel wire and the card slot 221 of mounting pin 22 is greater than
Boss 11 is connected and the gap of steel wire 21 is connected, otherwise, when pressing driver airbag 2, on the card slot 221 of mounting pin 22
The upper surface contact of the inside straight flange 32 of surface and fixed steel wire 3, when driver airbag 2 can not be moved downward further,
Conducting boss 11 and conducting steel wire 21 are still not in contact with then cannot achieve and press function aloud.
Referring to Fig. 7, the Z-direction width of the card slot 221 of 22 inside of mounting pin is I, then the movement travel of mounting pin 22 subtracts for I
The diameter of inside straight flange 32 is removed, and must assure that the movement travel of mounting pin 22 is more than conducting boss 11 and steel wire 21 is connected
Gap.The movement travel on the inclined-plane 222 in 22 outside of mounting pin is L simultaneously.
In Fig. 7, when driver airbag 2 is mounted on static on steering wheel 1, the outside straight flange 31 of fixed steel wire 3 is to peace
Pin 22 is filled there are one the tangential power F of opposed facets 222, which is decomposed into longitudinal F1 and lateral F2, wherein decomposite
The power of F1 offsets the gravity of driver airbag 2.Therefore, for fixed steel wire 3 in free state, outside straight flange 31 and inside are straight
Side 32 is not to maintain parallel state, and setting can inside contract state, i.e.,：Outside straight flange 31 and the threshold value of inside straight flange 32 are less than
The outside straight flange 31 of fixed steel wire 3 connect distance with the root of inside straight flange 32.Driver airbag 2 presses movement aloud downwards
When, the power F tangential to fixed 3 outside straight flange 31 of steel wire of mounting pin 22 increases, wherein resolving into Y-direction power F1 and X-direction power F2
Also increase.Y-direction F1 power is the gravity of driver airbag 2 and presses power aloud after increase.
