[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0034] like Figure 1 and Figure 2 and Figure 3 As shown, it includes a shell 1 and a base plate 2, the shell 1 is snapped onto the base plate 2, a penetrating fixing hole 21 is provided on the base plate 2, the fixing hole 21 is aligned with the interior of the car, a sink 211 is provided in the fixing hole 21, the sink 211 extends inwardly to form a surrounding wall 212 on the inner surface of the base plate 2, the outer surface of the base plate 2 is aligned with the interior of the car, the surrounding wall 212 protrudes from the inner surface of the base plate 2 to form an enclosed area, and the inner cavity of the surrounding wall 212 is communicated with the fixing hole 21.
[0035] The housing 1 includes an integrally formed cover plate 11 and a storage frame 12. The airbag is placed in the storage frame 12. A plurality of card blocks 13 are arranged on the storage frame 12. The card blocks 13 are connected to the ends of the surrounding wall 212. The storage frame 12 passes through the fixing hole 21. The cover plate 11 is laid flat in the sink 211, which is equivalent to the outer end of the fixing hole 21 being closed. The outer surface of the cover plate 11 is also aligned with the interior of the car. The storage frame 12 has a shell 16 extending inward from the inner surface of the cover plate 11. The opening of the storage frame 12 is located in the inner cavity of the surrounding wall 212. The storage frame 12 cannot fall off the surrounding wall 212. The shell 16 is surrounded by a circle to form a storage bin 17. The airbag is placed into the storage bin 17 from the opening of the storage frame 12, and then the airbag is stored in the storage bin 17. The opening end of the storage frame 12 is blocked by other accessories.
[0036] A seam strip 15 is provided on the middle line of the inner surface of the cover plate 11. The thickness of the seam strip 15 is less than that of the cover plate 11. The seam strip 15 can cooperate with the airbag to pop out in a way that it cracks when a collision occurs. The seam strip 15 is a groove. The seam strip 15 is sewn under normal conditions. Because the enclosed area of the surrounding wall 212 is connected to the fixing hole 21, and the storage frame 12 is located in the enclosed area of the surrounding wall 212, the extension direction of the shell 16 is consistent with the extension direction of the surrounding wall 212. Because the fixing hole 21 is aimed at the interior of the car, it is aimed at the driver and passengers when the airbag pops out, and the airbag pops out in a straight line, so the driver and passengers are protected to the maximum extent.
[0037] The surrounding wall 212 includes an inner wall body 213 and an outer wall body 214 arranged at intervals, a cavity is formed between the inner wall body 213 and the outer wall body 214, and a plurality of connecting pieces 215 are arranged at intervals between the inner wall body 213 and the outer wall body 214 to connect them. The two ends of the connecting piece 215 respectively abut the inner wall body 213 and the outer wall body 214. When the inner wall body 213 or the outer wall body 214 is squeezed, the inner wall body 213 or the outer wall body 214 can have a buffering effect. When not squeezed, the inner wall body 213 or the outer wall body 214 is reset under the action of the connecting piece 215. When the storage frame 12 is sleeved in the inner wall body 213, the shell 16 fits the inner wall body 213, and the block 13 squeezes the inner wall body 213.
[0038] There is a gap between the inner wall 213 and the outer wall 214, which can save materials.
[0039] A plurality of outwardly protruding grooves 217 are evenly arranged on the inner wall body 213, and the grooves 217 protrude and extend toward the outer wall body 214. A plurality of reinforcing strips 121 are evenly arranged on the shell body 16, and a pair of reinforcing strips 121 are accommodated in the grooves 217. The extension direction of the reinforcing strips 121 is consistent with the extension direction of the storage frame 12. An outer chamfer is arranged on the top of the reinforcing strip 121, and the outer chamfer is close to the opening end of the storage frame 12. The opening end of the storage frame 12 cooperates to place the airbag, so this outer chamfer avoids hurting people.
[0040] The housing 16 is provided with a plurality of wall holes 122 and a plurality of guide grooves 123. The guide grooves 123 extend from the opening end of the storage frame 12 to the upper part of the wall holes 122. The guide grooves 123 become thinner as they extend. The guide grooves 123 are for facilitating the fixed installation of the storage frame 12. When the airbag is compressed in the storage frame 12, the compressed airbag is dispersed into the wall holes 122.
[0041] The shell 16 is symmetrically provided with a first fixing groove 125 and a second fixing groove 126 , which facilitate the fixation of the storage frame 12 and the airbag in the accommodating compartment 17 .
[0042] The cover plate 11 is flush with the surface of the bottom plate 2, so that there are no protrusions on the outer surface of the bottom plate 2, and the outer surface of the bottom plate 2 is conducive to sticking to the foaming layer.
[0043] like Figure 4 As shown, a plurality of side holes 14 are evenly arranged on the shell 16, and the card block 13 is arranged at the upper end of the hole wall where the side hole 14 is located. The plurality of side holes 14 are arranged one by one corresponding to the card block 13. When the storage frame 12 is sleeved in the surrounding wall 212, the card block 13 slides and abuts against the inner wall of the surrounding wall 212. Because the card block 13 is squeezed by force, the card block 13 is compressed into the side hole 14.
[0044] A plurality of card slots 216 are provided at the end of the inner wall body 213, and the card block 13 slides against the inner wall body 213. The card slot 216 is located on the extended end of the inner wall body 213, and the plurality of card blocks 13 are carded in the card slots 216 one by one, so that the position of the storage frame 12 on the inner wall body 213 is fixed, and the storage frame 12 extends to the outer edge of the inner wall body 213, that is, the length of the storage frame 12 is longer than both the inner wall body 213 and the outer wall body 214.
[0045] like Figure 5 As shown, the block 13 includes a first angular body 131, a second angular body 132 and a connecting plate 133. The first angular body 131 and the second angular body 132 are respectively arranged on both sides of the connecting plate 133. The connecting plate 133 is connected to the shell 16. The first angular body 131 and the second angular body 132 are arranged at a distance from each other. The first angular body 131 and the second angular body 132 are both triangular bodies.
[0046] A plurality of transverse reinforcing ribs 127 and a plurality of longitudinal reinforcing ribs 128 are provided on the shell 16. The transverse reinforcing ribs 127 extend transversely on the outer wall of the storage frame 12, and the longitudinal reinforcing ribs 128 extend longitudinally on the outer wall of the storage frame 12. The transverse reinforcing ribs 127 intersect with the longitudinal reinforcing ribs 128. The transverse reinforcing ribs 127 and the longitudinal reinforcing ribs 128 are beneficial to the supporting effect of the storage frame 12.
[0047] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
