The reader will become apparent various aspects of the present utility model after the reference accompanying drawing has been read the specific embodiment of the present utility model.Wherein,
Fig. 1 shows the generalized section according to Automobile instrument airbag apparatus of the present utility model.
Fig. 2 shows the structural representation according to Automobile instrument airbag apparatus of the present utility model.
Fig. 3 and Fig. 4 show according to the schematic diagram during airbag deployment in the Automobile instrument airbag apparatus of the present utility model.
Fig. 5 shows the birds-eye view according to atenuator region among the embodiment of the present utility model.
The specific embodiment:
With reference to the accompanying drawings, the specific embodiment of the present utility model is described in further detail.
Fig. 1 shows the generalized section according to Automobile instrument airbag apparatus of the present utility model.With reference to Fig. 1, the instrument carrier panel of automobile has body 10, and body 10 has atenuator region 11.Fig. 5 shows the birds-eye view according to atenuator region among the embodiment of the present utility model.With reference to Fig. 5, atenuator region 11 is rendered as two rectangles with common edge in the present embodiment.Atenuator region 11 has two the first fracture positions 111 and one second fracture position 112.
Continuation is with reference to Fig. 1, and the Automobile instrument airbag apparatus comprises air bag 20, two air bag cover plates 21, support 22 and position limiting structure (not indicating).Wherein, air bag 20 is fixed on the instrument carrier panel by linking up with 23, particularly, can be fixed on the Guan Liang (not illustrating) of instrument carrier panel.Two air bag cover plates 21 are fixed in the body 10 of instrument carrier panel towards a side of air bag 20 by friction welding, two air bag cover plates 21 cover air bag 20, the second fracture position 112 is corresponding between two air bag cover plates 21, and the second fracture position 112 has been realized a balloon perforation when air bag 20 explosion.Support 22 is positioned at the both sides of air bag cover plate 21, and is fixed in the body 10 of instrument carrier panel towards a side of air bag 20 with two air bag cover plates 21 by friction welding, and each first fracture position 111 is corresponding to the position between support 22 and each air bag cover plate 21.
Fig. 2 shows the structural representation according to Automobile instrument airbag apparatus of the present utility model.With reference to Fig. 2, be provided with groove 221 on the support 22, particularly, groove 221 is dovetail furrow, and respective slot 221 is provided with the first projection 211, the first projections 211 and is positioned at groove 221 on each air bag cover plate 21, and it has a sliding space in groove 221.Groove 221 can be set to a plurality of, and correspondingly, the first projection 211 also is set to a plurality of, and each first projection 211 is positioned at each groove 221.
Fig. 3 and Fig. 4 show according to the schematic diagram during airbag deployment in the Automobile instrument airbag apparatus of the present utility model.With reference to Fig. 4, can exert pressure to air bag cover plate 21 when air bag 20 launches first, this pressure is so that the body 10 of instrument carrier panel ruptures along the second fracture position 112, and two air bag cover plates 21 rotate around hinge area 24, and the formation balloon perforation allows air bag 20 pass.
Again in conjunction with Fig. 2 with reference to Fig. 3, when air bag 20 explosion, can exert pressure to air bag cover plate 21, this pressure simultaneously so that the body 10 of instrument carrier panel along 111 fractures of the first fracture position, and because the effect of pressure, the first projection 211 of air bag cover plate 21 is in groove 221 interior slips, so that each air bag cover plate 21 moves along the direction away from another part 10b that is attached to the body 10 on the support 22 with a part of 10a of body attached to it 10, therefore, a part of 10a of body 10 and another part 10b are at a distance of a segment distance.
Refer again to Fig. 4, when air bag cover plate 21 rotates around hinge area 24, the end of another part 10b of the end of a part of 10a of body 10 and body 10 can not interfere, thus the phenomenon that the body 10 that has solved instrument carrier panel breaks because of interference when fracture.
Continuation in conjunction with Fig. 2 with reference to Fig. 1, although groove 221 defines the space that the first projection 211 is slided within it, but when air bag 20 launches, the distance that skids off in order to limit better air bag cover plate 21, in the present embodiment, can also pass through position limiting structure (not indicating), limit the position that air bag cover plate 21 slides.For example, can be by the first depression 212 be set at air bag cover plate 21, correspondence arranges the second depression 222 on support 22, when air bag cover plate 21 when the direction of body 10 is slided, the lower edge of the first depression 212 can block the upper limb of the second depression 222, reaches the position that restriction air bag cover plate 21 slides with this.Certainly, the position of sliding in order to limit better air bag cover plate 21, the first depression the 212 and second depression 222 can be arranged to through hole, and will link up with 23 and pass the first depression the 212 and second depression 222, after air bag cover plate 21 slided a segment distance, hook 23 can play the work of bolt in order to limit the position of air bag cover plate 21 slips.Certainly, position limiting structure is not as limit, in a further embodiment, bayonet socket can also be set by the both sides at support 22 and at air bag cover plate 21 the second projection be set simultaneously, after air bag cover plate 21 slides a segment distance, the second projection falls in the bayonet socket, can limit equally the position that air bag cover plate 21 slides.
The utility model has the advantages that: by at support groove being set; at air bag cover plate projection is set accordingly; projection is positioned at groove a sliding space; when air bag cover plate ruptures along predefined fracture position; air bag cover plate slides in groove by projection; make between the instrument carrier panel of disconnection at a distance of a segment distance; avoided instrument carrier panel to interfere each other and breaking of causing; thereby prevent that breakage from cutting air bag and making air bag lose protection occupant's meaning, simultaneously can prevent that also fragment from damaging the occupant.
Above demonstration and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
