[0001] This utility model belongs to the field of automotive airbag technology, and more specifically, it relates to an airbag frame. Background Technology

[0002] Airbags, as a crucial component of a vehicle's structure and belonging to the auxiliary restraint system, play a primary role in protecting occupants' passive safety. The airbag frame, as a vital part of the passenger-side airbag system, determines the successful deployment of the PAB (Park Airbag). With the rapid evolution and diversification of automotive interior designs, improved airbag frame structures can adapt to new vehicle models. However, existing technologies suffer from the following drawbacks: When the airbag deploys, the frame may crack uncontrollably, and the resulting fragments can easily cause secondary injuries.

[0003] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a safety airbag frame. The airbag frame has a flexible hinge structure to prevent it from being stuck when the airbag is deployed. When the airbag is detonated, the entire airbag frame is disconnected from the first connecting block, the second connecting block, and the third connecting block, and the first cover plate and the second cover plate are deployed. This design can reduce the risk of fragments flying and avoid secondary injury to passengers.

[0005] An airbag frame includes a base plate and an airbag frame body fixedly connected to the base plate. Side fixing points are fixedly connected to the short sides of both sides of the airbag frame body. Multiple hook holes one and hook holes two are respectively opened on the long sides of both sides of the airbag frame body. A guide slope is opened on the airbag frame body above the hook holes two. Multiple stiffening plates are fixedly connected to the long sides of both sides of the airbag frame body. One end of the stiffening plate is fixedly connected to the base plate.

[0006] Preferably, the base plate has a through hole in the middle, and a first cover plate and a second cover plate are hinged to the long side of the through hole respectively. A connecting block 1 is fixedly connected to the short side of the first cover plate and the connecting block 1 is fixedly connected to the base plate. A connecting block 3 is fixedly connected to the short side of the second cover plate and the connecting block 3 is fixedly connected to the base plate. Two connecting blocks 2 are fixedly connected to the long side of the first cover plate near the second cover plate and the two connecting blocks 2 are fixedly connected to the second cover plate.

[0007] Preferably, a positioning point one is provided in the middle of the long side of one side of the base plate, and groove one and groove two are provided on the base plate on both sides of the positioning point one, respectively. Groove four and groove three are provided on the long side of the other side of the base plate, and positioning point two is provided on both short sides of the base plate.

[0008] Preferably, the bottom plate, the first cover plate, and the second cover plate are fixedly connected to the surface of the airbag frame with multiple welded ribs facing away from each other.

[0009] Preferably, the number of hook holes one and hook holes two are different.

[0010] Preferably, the base plate and the airbag frame are welded using vibration friction welding.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention has the following advantages: the airbag frame has a flexible hinge structure to prevent it from getting stuck when the airbag deploys; when the airbag is detonated, the entire airbag frame breaks off from connecting block one, connecting block two, and connecting block three, and the first cover plate and the second cover plate unfold. This design can reduce the risk of debris flying and prevent passengers from suffering secondary injuries; the airbag frame can evenly disperse the impact force of the airbag expansion within milliseconds and unfold along a predetermined route.

[0014] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] like Figures 1 to 4As shown, an airbag frame includes a base plate 1 and an airbag frame 2 fixedly connected to the base plate 1. Side fixing points 201 are fixedly connected to the short sides of both sides of the airbag frame 2, securing the airbag to the vehicle body. Multiple hook holes 202 and 203 are respectively provided on the long sides of both sides of the airbag frame 2. A guide slope 204 is provided on the airbag frame 2 above the hook holes 203. The guide slope 204 facilitates airbag installation and helps determine the airbag's installation direction. Multiple stiffening plates 205 are fixedly connected to the long sides of both sides of the airbag frame 2. One end of each stiffening plate 205 is fixedly connected to the base plate 1, reinforcing the base plate 1 and the airbag frame 2.

[0016] A through hole is provided in the middle of the base plate 1. A first cover plate 107 and a second cover plate 111 are hinged to the long side of the through hole. The first cover plate 107 and the second cover plate 111 are flexibly hinged to the base plate 1. When the airbag is deployed, the first cover plate 107 and the second cover plate 111 can be connected to the base plate 1 to prevent the first cover plate 107 and the second cover plate 111 from breaking and being thrown out, causing secondary injury to the passenger. A connecting block 108 is fixedly connected to the short side of the first cover plate 107 and is fixedly connected to the base plate 1. A connecting block 110 is fixedly connected to the short side of the second cover plate 111 and is fixedly connected to the base plate 1. Two connecting blocks 109 are fixedly connected to the long side of the first cover plate 107 near the second cover plate 111 and are fixedly connected to the second cover plate 111. There are six connecting blocks in total: 108 (connecting block 1), 109 (connecting block 2), and 110 (connecting block 3), which connect the first cover plate 107 and the second cover plate 111 respectively, and also connect the first cover plate 107 and the second cover plate 111 to the base plate 1. In this utility model, the thickness of the first cover plate 107 and the second cover plate 111 is 3.5mm to ensure that the airbag will not tear due to insufficient strength when it bursts; the thickness of the airbag frame 2 is 4mm to ensure that the airbag has sufficient strength when it rebounds after bursting.

[0017] A positioning point 102 is provided in the middle of the long side of one side of the base plate 1. Grooves 101 and 103 are respectively provided on the base plate 1 on both sides of positioning point 102. Grooves 4 105 and 106 are provided on the long side of the other side of the base plate 1. Positioning points 2 104 are provided on both short sides of the base plate 1. The presence of one positioning point 102 and two positioning points 2 104 on the base plate 1 primarily restricts the longitudinal and lateral movement of the base plate 1. The base plate 1 and the airbag frame 2 are welded using vibration friction welding.

[0018] The base plate 1, the first cover plate 107, and the second cover plate 111 are fixedly connected to the surface of the airbag frame 2 with multiple welded ribs facing away from each other. The height of the welded ribs is 2mm, the welding depth is 1mm, the spacing between the welded ribs is 6mm, and the width of the welded ribs is 3mm to ensure the strength of the weld. The number of hook holes 1 202 and hook holes 203 are different. The advantage of this design is that it can prevent the airbag from being installed backwards.

[0019] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
