Specific implementation

[0039] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model more clear, the technical scheme in the embodiment of the utility model will be described clearly and completely below with the drawings in the embodiment of the utility model, obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the skilled in the art without making creative labor are within the protection scope of the utility model.

[0040] In the related art, in order to improve the visual effect or install other components, the groove is provided on the side of the cover away from the air bag, the groove is recessed towards the air bag, and the groove forms a convex structure on the side of the cover close to the air bag. For example, the groove can be used to install the signboard of the carrier or the manufacturer.

[0041] However, when the air bag is triggered, the air bag will impact in the weakest direction, for the cover provided with the groove, the groove is prone to deformation and bulging at this time, which may cause the air bag to fail to pass out and unfold according to the preset path, affecting the unfolding effect of the air bag.

[0042] Although the thinning line is arranged outside the convex structure, the strength of the thinning line can be too large, so that the problem of the groove being first driven to bulge and then the thinning line being torn can still occur during the deployment of the airbag.

[0043] To solve or improve the problem that the groove on the airbag cover is easy to deform and bulge, which can cause the safety airbag to fail to pass out and deploy along the preset path, and to achieve the effect of making the tearing line more easily torn, the embodiments of the present application provide an airbag cover, a safety airbag device, a steering wheel assembly and a vehicle.

[0044] The embodiments of the present application will be described below in combination with Figures 1 to 10 The airbag cover 100 provided in the embodiments of the present application will be described. The airbag cover 100 is used to cover a safety airbag.

[0045] Specifically, the airbag cover 100 includes a main body 1. Optionally, the main body 1 is arranged in a plate structure, for example, the main body 1 can be arranged as a plastic plate. The main body 1 has opposite first and second surfaces 101 and 102, for example, in the state that the airbag cover 100 covers the safety airbag, the surface of the main body 1 close to the safety airbag is the first surface 101, and the surface of the main body 1 away from the safety airbag is the second surface 102.

[0046] The first surface 101 is provided with a groove 103, the groove 103 is recessed toward the second surface 102, and the second surface 102 forms a convex structure 104. That is, due to the recess of the groove 103 toward the second surface 102, the second surface 102 forms the convex structure 104, so that the thickness of the main body 1 does not need to be increased, and the groove 103 can be formed on the main body 1, which helps to reduce the material usage of the airbag cover 100, so that the airbag cover 100 is lighter and has lower cost. The groove 103 has a slot opening toward a direction away from the second surface 102, and the groove 103 can be used to accommodate a sign 6.

[0047] The second surface 102 is provided with a first weakening structure 102a. The first weakening structure 102a includes a first thinning line 105 and a through hole 106. The main body 1 has a smaller thickness at the part of the first thinning line 105, so as to make the first thinning line 105 more easily torn.

[0048] Among them, at least part of the first thinning line 105 is circumferentially arranged outside the convex structure 104. The part of the first thinning line 105 circumferentially arranged outside the convex structure 104 is provided with the through hole 106, that is, the part of the first thinning line 105 circumferentially arranged outside the convex structure 104 is provided with the through hole 106, or the entire region of the first thinning line 105 circumferentially arranged outside the convex structure 104 is distributed with the through hole 106.

[0049] The through hole 106 penetrates the main body 1 from the first surface 101 to the second surface 102. That is, the through hole 106 can reduce the overall continuity of the material, reduce the tensile strength at the fracture initiation point, and thus require a smaller force to start tearing the material.

[0050] In the embodiment, by arranging the recess 103 on the first surface 101, the signboard 6 can be accommodated in the recess 103. By making the recess 103 recessed towards the second surface 102 and making the second surface 102 form a protruding structure 104, the weight of the main body 1 is reduced, and the cost of the main body 1 is reduced.

[0051] By arranging the first thinning line 105 on the outer side of the protruding structure 104 in the circumferential direction, and the part of the first thinning line 105 surrounding the protruding structure 104 is provided with the through hole 106, the arrangement of the through hole 106 can further reduce the structural strength of the first thinning line 105, so that the first thinning line 105 is more easily torn, so that in the process of the airbag pushing the protruding structure 104, when the protruding structure 104 produces a small deformation, the first thinning line 105 of the protruding structure 104 in the circumferential direction is torn, the influence of the deformation of the protruding structure 104 on the airbag deployment is reduced, and the probability that the airbag cannot be deployed according to the preset path is reduced.

[0052] In some embodiments of the utility model, the first weakening structure 102a further includes a second thinning line 107 and a third thinning line 108, and the second thinning line 107 and the third thinning line 108 are distributed on opposite sides of the protruding structure 104.

[0053] For example, as shown in Figure 6 、 Figure 8 and Figure 9 , the second thinning line 107 and the third thinning line 108 are distributed on the left and right sides of the protruding structure 104, and the second thinning line 107 and the third thinning line 108 are both arranged in a spaced manner with the protruding structure 104.

[0054] Correspondingly, the first thinning line 105 is arranged between the second thinning line 107 and the third thinning line 108, and the first thinning line 105 includes a first connecting segment 1051, a surrounding segment 1052 and a second connecting segment 1053 connected in sequence.

[0055] Among them, the surrounding segment 1052 surrounds at least part of the protruding structure 104 along the circumferential direction of the protruding structure 104, and the surrounding segment 1052 is provided with the through hole 106. Optionally, the surrounding segment 1052 can be arranged in imitation of the outer contour of the protruding structure 104.

[0056] For example, as shown in Figure 5As shown, the protruding structure 104 is provided as a cylindrical protrusion, and the surrounding segment 1052 is provided as an arc-shaped structure. Of course, in some unillustrated embodiments, the protruding structure 104 can also be provided as a polygonal structure, and the surrounding segment 1052 can be provided as a polyline structure or an arc-shaped structure, wherein the polyline structure includes a plurality of sequentially connected line segments.

[0057] The first connecting segment 1051 is connected with the second thinning line 107, for example, one end of the first connecting segment 1051 is connected with one end of the surrounding segment 1052 away from the second connecting segment 1053, and the other end of the first connecting segment 1051 intersects with the second thinning line 107. It can be understood that the extending directions of the first connecting segment 1051 and the second thinning line 107 intersect. For example, the first connecting segment 1051 intersects with the middle position of the second thinning line 107.

[0058] The second connecting segment 1053 is connected with the third thinning line 108, for example, one end of the second connecting segment 1053 is connected with one end of the surrounding segment 1052 away from the first connecting segment 1051, and the other end of the second connecting segment 1053 intersects with the third thinning line 108. It can be understood that the extending directions of the second connecting segment 1053 and the third thinning line 108 intersect. For example, the second connecting segment 1053 intersects with the middle position of the third thinning line 108.

[0059] In the present embodiment, reference can be made to Figure 6 , Figure 8 and Figure 9 During the unfolding of the airbag, the airbag pushes the protruding structure 104, and the surrounding segment 1052 outside the protruding structure 104 first tears, and the tear is transmitted to the second thinning line 107 and the third thinning line 108 along the first connecting segment 1051 and the second connecting segment 1053, respectively.

[0060] After the second thinning line 107 and the third thinning line 108 are torn, under the segmentation action of the second thinning line 107 and the third thinning line 108, the connection strength between the materials on both sides of the first thinning line 105 and other parts of the main body 1 decreases, so that the folding deformation outward can be more easily generated, so as to make the main body 1 generate a larger breaking range, and facilitate the airbag to pass out of the main body 1.

[0061] Reference can be made to Figure 6 , Figure 8 and Figure 9 In some embodiments provided by the present application, the surrounding segment 1052 surrounds one side of the protruding structure 104. For example, as shown in Figure 6 , Figure 8 and Figure 9 The surrounding segment 1052 surrounds the upper side of the protruding structure 104.

[0062] Further, the airbag cover 100 further comprises a reinforcing rib 109.

[0063] Specifically, the reinforcing rib 109 is arranged on the second surface 102 and located on a side of the protruding structure 104 away from the surrounding section 1052. For example, as shown in Figure 6 、 Figure 8 and Figure 9 illustrated, at least part of the reinforcing rib 109 extends onto the protruding structure 104.

[0064] In the embodiment, by arranging part of the reinforcing rib 109 on the second surface 102 and part of the reinforcing rib 109 on the protruding structure 104, on the one hand, the rigidity of the protruding structure 104 can be improved, and the problem that the protruding structure 104 is easily deformed can be avoided, thereby reducing the influence of the protruding structure 104 on the airbag deployment and reducing the probability that the airbag cannot be deployed according to the preset path.

[0065] On the other hand, the connection strength of the protruding structure 104 and the second surface 102 can be improved, and the problem that the protruding structure 104 is displaced relative to the second surface 102 to the first surface 101 can be avoided, thereby reducing the influence of the protruding structure 104 on the airbag deployment and reducing the probability that the airbag cannot be deployed according to the preset path.

[0066] By arranging the reinforcing rib 109 on a side of the protruding structure 104 away from the surrounding section 1052, the influence of the reinforcing rib 109 on the easy tearing characteristics of the surrounding section 1052 can be avoided.

[0067] In some embodiments provided by the present application, the first thinning line 105 is provided with a plurality of through holes 106, and the plurality of through holes 106 are arranged at intervals along the extension direction of the first thinning line 105.

[0068] In the embodiment, the existence of the through hole 106 breaks the material continuity at the first thinning line 105, and when subjected to an external force, the first thinning line 105 is more likely to tear, thereby enhancing the weakening effect of the first thinning line 105.

[0069] The interval arrangement of the plurality of through holes 106 can make the weakening effect of the first thinning line 105 along the line more uniform, otherwise it may cause the strength of some parts of the thinning line to be too high or too low, and the airbag may be unevenly broken or not smoothly deployed when the airbag is deployed, thereby affecting the normal deployment of the airbag.

[0070] Referring to Figure 3 illustrated, in some embodiments provided by the present application, the groove bottom of the groove 103 is provided with a boss 110. Specifically, the boss 110 protrudes from the groove bottom of the groove 103 along the depth direction of the groove 103.

[0071] In the embodiment, the boss 110 is arranged at the bottom of the groove 103. On one hand, the boss 110 can support the signboard 6. When the signboard 6 is arranged in the groove 103, the boss 110 supports the signboard 6, thereby avoiding the problem that the signboard 6 is dented or deformed due to impact or long-term pressing.

[0072] Alternatively, the boss 110 can position the signboard 6. For example, the signboard 6 is arranged with a limiting structure, such as a limiting groove, near the surface of the boss 110. In the state that the signboard 6 is arranged in the groove 103, the boss 110 can limit the signboard 6 in the direction perpendicular to the depth direction of the groove 103, so that the signboard 6 has an accurate installation position, thereby ensuring that the installation position of the signboard 6 is accurate and avoiding the problem that the signboard 6 is loose and displaced after long-term use.

[0073] As shown in Figure 2 and Figure 3 optionally, the boss 110 can be arranged at the center of the bottom of the groove 103, so that the boss 110 can support the signboard 6 at the center position, thereby providing better support for the signboard 6.

[0074] As shown in Figure 3 in some embodiments of the utility model, the bottom of the groove 103 is arranged with a connecting hole 111, and the connecting hole 111 penetrates the bottom of the groove 103 in the depth direction of the groove 103.

[0075] Further, the cover further comprises a signboard 6. The signboard 6 is arranged with a connecting part which penetrates the connecting hole 111 and is connected with the main body 1. Optionally, the connecting part can be bonded, screwed or riveted with the main body 1. Alternatively, the part of the connecting part penetrating the connecting hole 111 is folded to form a flange, and the flange abuts against the second surface 102, so that the signboard 6 is connected with the main body 1.

[0076] For example, the signboard 6 can be an aluminum plate, a copper plate or a stainless steel plate, and the connecting part can be a connecting sheet or a connecting lug.

[0077] As shown in Figure 5 and Figure 6 in some embodiments of the utility model, the protruding structure 104 is arranged with a recessed part on the end surface away from the first surface 101. The recessed part is recessed towards the inside of the groove 103, and the bottom of the groove 103 is arranged with the boss 110.

[0078] In the embodiment, the boss 110 is arranged at the bottom of the groove 103. On one hand, the boss 110 can support the signboard 6. When the signboard 6 is arranged in the groove 103, the boss 110 supports the signboard 6, thereby avoiding the problem that the signboard 6 is dented or deformed due to impact or long-term pressing.

[0079] In some embodiments of the present application, the airbag cover 100 further comprises a skin 2. Optionally, the skin 2 can be provided as a leather.

[0080] The skin 2 covers at least part of the first surface 101 and covers the through hole 106. The skin 2 is provided with an adapter 201 opposite the groove 103, the adapter 201 protrudes from the surface of the skin 2 close to the main body 1, and the adapter 201 is arranged in the groove 103.

[0081] In this embodiment, by covering the skin 2 on the first surface 101, the texture and visual effect of the airbag cover 100 can be improved. By covering the skin 2 on the through hole 106, on the one hand, it can prevent dust and other impurities from entering the inside of the safety airbag device through the through hole 106, affecting the parts inside the safety airbag device, and on the other hand, it can avoid the through hole 106 causing negative effects on the visual effect and texture of the airbag cover 100.

[0082] By arranging the adapter 201 on the skin 2 in the groove 103, on the one hand, it can form a more fitted covering effect on the groove 103, thereby avoiding the edges of the groove 103 being exposed, so as to improve the texture of the airbag cover 100, and on the other hand, it can avoid the signboard 6, so that the signboard 6 can be arranged in the groove 103 and press the skin 2.

[0083] Further, for the embodiment in which the bottom of the groove 103 is provided with a boss 110, the skin 2 is provided with an opening 202 corresponding to the boss 110, and the opening 202 is used to avoid the boss 110, so that the boss 110 can pass through the boss 110 to support or position the signboard 6.

[0084] Optionally, the skin 2 is provided with an avoidance hole 203 corresponding to the connecting hole 111, so that the connecting part of the signboard 6 can pass through the avoidance hole 203 and enter the connecting hole 111.

[0085] Optionally, the skin 2 can be bonded to the first surface 101 of the main body 1.

[0086] Optionally, in order to reduce the obstruction caused by the skin 2 to the tearing of the main body 1, the thickness of the skin 2 can be reduced, for example, the thickness of the skin 2 is less than or equal to 1mm. For example, the thickness of the skin 2 is 0.8mm.

[0087] Of course, it is not limited to reducing the thickness of the skin 2 to reduce the obstruction caused by the skin 2 to the tearing of the main body 1, for example, in another embodiment of the present application, the surface of the skin 2 close to the main body 1 is provided with a second weakening structure 204, and the second weakening structure 204 extends along the first weakening structure 102a.

[0088] Optionally, the second weakening structure 204 extends along the first thinning line 105, the second thinning line 107 or the third thinning line 108. Further, the skin 2 is provided with the second weakening structure 204 corresponding to the first thinning line 105, the second thinning line 107 and the third thinning line 108 of the first weakening structure 102a.

[0089] In the embodiment, the second weakening structure 204 extends along the first weakening structure 102a, so that the breaking position of the skin 2 and the main body 1 can be more accurately controlled, and the breaking occurs along the preset first weakening structure 102a and the corresponding second weakening structure 204 during the airbag deployment, so that irregular breaking is avoided, the channel through which the airbag passes is neat and smooth, and the normal deployment and protection of the airbag are facilitated.

[0090] By arranging the second weakening structure 204 on the surface of the skin 2 close to the main body 1, the second weakening structure 204 is invisible, so that the second weakening structure 204 does not have a negative impact on the visual effect and texture of the surface of the skin 2.

[0091] In some embodiments of the utility model, the second weakening structure 204 comprises a plurality of pits 2041, and the plurality of pits 2041 are arranged at intervals along the extension direction of the first weakening structure 102a.

[0092] In the embodiment, the second weakening structure 204 comprises a plurality of pits 2041 arranged at intervals, and the material between adjacent pits 2041 is not lost, that is, the thickness of the skin 2 at the pit 2041 is thinned, and the thickness between adjacent pits 2041 is unchanged. In this way, the pit 2041 can weaken the skin 2, and the material between the pits 2041 can form a supporting effect, avoiding the problem that the surface of the skin 2 away from the main body 1 is dented after being pressed for a long time.

[0093] Optionally, along the extension direction of the first weakening structure 102a, the total length of the pit 2041 is half of the total length of the first thinning line 105. Of course, the total length of the pit 2041 can also be greater than or less than the total length of the first thinning line 105.

[0094] Optionally, the pit 2041 can be processed by laser or cold knife.

[0095] The utility model discloses an airbag device.
