[0037] The preferred embodiments of the present utility model are given below in conjunction with the accompanying drawings and described in detail.

[0038] like Figure 1A , Figure 1B and Figure 1CAs shown, the embodiment of the utility model provides an airbag installation assembly 100, which is used to fix the airbag 200 on the vehicle body structure 300, and the vehicle body structure 300 is provided with a plurality of studs 310, and the airbag 200 includes an airbag 210, and the airbag 210 is provided with a plurality of airbag fixing sheets 211, and each airbag fixing sheet 211 is assembled with a stud 310 through an airbag installation assembly 100, so that the airbag fixing sheet 211 is fixed to the vehicle body structure 300. When the airbag 210 is fixed to the vehicle body structure 300, it is in a folded state (for example, folded into a roll with a circular cross section) to reduce space occupation; a dust cover 220 can be provided on the outside of the airbag 210 to isolate the airbag 210 from the outside and play a dustproof role. The dust cover 220 can also be connected to the airbag installation assembly 100 to support it through the airbag installation assembly 100, so that the airbag 210 and the dust cover 220 reach a preset package shape. During a collision, the airbag 200 will be triggered (for example, by a gas generator), and the airbag 210 will break through the dust cover 220 and unfold. The unfolded airbag 210 will be suspended on the vehicle body structure 300 through the airbag mounting components 100 and located between the vehicle body structure 300 and the occupant, thereby preventing the occupant from directly colliding with the vehicle body structure 300, thereby playing a protective role.

[0039] like Figure 2A , Figure 2B and Figure 2C As shown, the airbag mounting assembly 100 of the first embodiment of the utility model includes an auxiliary mounting plate 110 and a flange nut 120. A mounting groove 111 and a plurality of first anti-slip limiting structures 112 are provided on a first side (i.e., a side away from the vehicle body structure 300) of the auxiliary mounting plate 110. The plurality of first anti-slip limiting structures 112 are arranged around the mounting groove 111. A first through hole 113 for the stud 310 to pass through is provided in the mounting groove 111. The flange nut 120 includes a flange plate 121 and a nut 122 fixed on the flange plate 121. The flange plate 121 can be mounted in the mounting groove 111 and limited by the plurality of first anti-slip limiting structures 112, so that the flange nut 1 20 is installed on the auxiliary mounting plate 110. After being installed on the auxiliary mounting plate 110, the flange nut 120 is restricted in the mounting groove 111, but can rotate around its own axis in the mounting groove 111. The flange 121 is provided with a second through hole for the stud 310 to pass through; during installation, the airbag fixing plate 211 is located between the auxiliary mounting plate 110 and the vehicle body structure 300, and the stud 310 passes through the airbag fixing plate 211, the auxiliary mounting plate 110, the flange 121 and the nut 122 in sequence, and is threadedly connected with the nut 122. By tightening the nut 122, the nut 122 can be fastened to the stud 310, so that the airbag fixing plate 211 is fixed to the vehicle body structure 300.

[0040] In an exemplary embodiment, there are three first anti-slip limiting structures 112 , which are evenly arranged along the circumference of the installation groove 111 .

[0041] One end of the first anti-dropping limiting structure 112 can extend on the plane where the auxiliary mounting plate 110 is located to exceed the plane where the mounting groove 111 is located (that is, it is located above the mounting groove 111), forming a suspended end. When the flange 121 is located in the mounting groove 111, the suspended end can hold the flange 121 in place so that it cannot fall off from the mounting groove 111.

[0042] like Figure 2D As shown, when the flange nut 120 is installed on the auxiliary mounting plate 110, the flange 121 can be obliquely inserted into the mounting groove 111. After the flange 121 is inserted into the mounting groove 111, the first anti-slip limiting structure 112 is located on the outside of the flange 121 to prevent it from falling off, and the nut 122 protrudes from the plane where the auxiliary mounting plate 110 is located. In order to facilitate the oblique insertion of the flange 121 into the mounting groove 111, the side of the suspended end of the first anti-slip limiting structure 112 away from the mounting groove 111 is an inclined surface, which is inclined toward the mounting groove 111, so that the flange 112 can slide into the mounting groove 111 along the inclined surface.

[0043] like Figure 3A As shown, the airbag fixing plate 211 may include a first section 2111, a bending section 2112 and a second section 2113 which are arranged in sequence, the first section 2111 and the second section 2113 are arranged opposite to each other, and are sewn together by a pre-sewn structure 2114 (for example, the first section 2111 and the second section 2113 are sewn together on both sides by needle and thread) to fix the first section 2111 and the second section 2113, and an installation space 2115 for accommodating the auxiliary installation plate 110 is formed between the first section 2111 and the second section 2113, and a fourth through hole 2116 is provided on the first section 2111 and the second section 2113.

[0044] The auxiliary mounting plate 110 may be provided with at least one (eg, two) hooks 114 (eg, Figure 2A As shown), a cutout 221 is provided on the dust cover 220, and the hook 114 can be inserted into the cutout 221 so that the dust cover 220 is fixedly connected to the auxiliary mounting plate 110.

[0045] like Figure 3B As shown, during installation, the auxiliary mounting plate 110 can be first placed in the installation space 2115, the nut 122 can be extended from the fourth through hole 2116 on the first section 2111, and then the hook 114 of the auxiliary mounting plate 110 can be inserted into the cutout 221 to fix the auxiliary mounting plate 110 and the dust cover 220.

[0046] like Figure 3CAs shown, after the auxiliary mounting plate 110 is installed to the airbag fixing plate 211, the auxiliary mounting plate 110 and the airbag fixing plate 211 can be moved as a whole to the vehicle body structure 300, and the stud 310 is passed through the second section 2113, the auxiliary mounting plate 110, the flange plate 121 and the nut 122 in sequence, and then the nut 122 is rotated to tighten the nut 122 and the stud 310, and the airbag fixing plate 211 is pressed against the vehicle body structure 300, thereby achieving the fixation of the airbag 200 and the vehicle body structure 300.

[0047] like Figure 4 As shown, the airbag mounting assembly 100 of the first embodiment of the utility model can also cooperate with the bolt 400 to fix the airbag 200 to the vehicle body structure 300. Specifically, the vehicle body structure 300 is provided with a bolt mounting hole, and the bolt 400 passes through the nut 122, the flange 121, the auxiliary mounting sheet 110, the airbag fixing sheet 211 and the bolt mounting hole in sequence, and is fastened with the bolt mounting hole, so as to fix the airbag 200 on the vehicle body structure 300.

[0048] In some embodiments, the auxiliary mounting plate 110 may be made of plastic, and the flange 121 and the nut 122 may be made of metal.

[0049] In some embodiments, the airbag may be an air curtain (also referred to as a head airbag, curtain airbag, etc.), which is installed on the top of the car to protect the head of the occupant from the side. The airbag fixing piece 211 may be an ear piece protruding from the airbag 210, and the airbag 210 is fixed to the vehicle body structure 300 through a plurality of ear pieces.

[0050] In the airbag mounting assembly 100 of the first embodiment of the present invention, the auxiliary mounting plate 110 can be mounted on the airbag fixing plate 211, and the stud 310 can be assembled with the flange nut 120 pre-installed on the auxiliary mounting plate 110, so as to fix the airbag 200 on the vehicle body structure.

[0051] like Figure 5A and Figure 5BAs shown, the second embodiment of the utility model provides an airbag installation assembly 100, which has a substantially same structure as the airbag installation assembly of the first embodiment, except that the connection method between the auxiliary installation piece 110 and the flange nut 120 is different. Specifically, the airbag installation assembly 100 of the second embodiment includes an auxiliary installation piece 110 and a flange nut 120 fixed on the auxiliary installation piece 110, the auxiliary installation piece 110 is provided with a first through hole 113, two opposite clamping grooves 114, a first blocking block 115 and a second blocking block 116, the first blocking block 115 and the second blocking block 116 are arranged oppositely, the two clamping grooves 114, the first blocking block 115 and the second blocking block 116 are arranged around the first through hole 113 and define a first limiting space 117, the flange piece 121 of the flange nut 120 is located in the first limiting space 117, and is limited by the two clamping grooves 114, the first blocking block 115 and the second blocking block 116.

[0052] Both sides of the first blocking block 115 are provided with weakened holes 1151 to weaken its structural strength. When the first blocking block 115 is subjected to external force, the first blocking block 115 is easily deformed, so that the flange 121 is easily installed in the first limiting space 117. Specifically, the flange 121 can be obliquely inserted into the first limiting space 117 from the first blocking block 115. Under the pressure of the flange 121, the weakened hole 1151 of the first blocking block 115 will be compressed and deformed, so that the lower part of the first blocking block 115 is inclined, that is, the top surface of the first blocking block 115 is formed into an inclined surface, so as to guide the flange 121 and make it smoothly inserted into the first limiting space 117. After the flange 121 enters the first limiting space 117, the pressure on the first blocking block 115 disappears, and the first blocking block 115 will return to its original state and block the flange 121 to limit it in the first limiting space 117 and prevent it from falling off from the auxiliary installation piece 110.

[0053] like Figure 5C As shown, when installing the flange nut 120, it can be installed from the first blocking block 115. Specifically, the flange nut 120 can be attached to the first blocking block 115 and pressed downward to compress and deform the first blocking block 115, and then the flange 121 can be obliquely inserted into the first limiting space 117 along the first blocking block 115. When the flange 121 is completely inserted into the first limiting space 117, the first blocking block 115 returns to its original state. At this time, the left and right sides of the flange 121 are respectively inserted into the two slots 114, the upper side of the flange 121 is blocked and limited by the first blocking block 115, and the lower side of the flange 121 is blocked and limited by the second blocking block 116. In this way, the flange 121 can be limited in the first limiting space 117 by the two slots 114, the first blocking block 115 and the second blocking block 116 to prevent it from falling off, thereby realizing the assembly of the flange nut 120 and the auxiliary mounting plate 110.

[0054] The airbag installation assembly 100 of the second embodiment of the present invention weakens the first blocking block 115 through the weakened hole 1151 to make it easier to deform, so that the flange 121 can be more easily inserted into the first limiting space 117 for easy installation.

[0055] like Fig. 6A , Figure 6B , Figure 6C and Fig.6D As shown, the third embodiment of the utility model provides an airbag installation assembly 100, which has a substantially same structure as the airbag installation assembly of the first embodiment, except that the connection method between the auxiliary installation piece 110 and the flange nut 120 is different. Specifically, the airbag mounting assembly 100 of the third embodiment includes an auxiliary mounting piece 110 and a flange nut 120 mounted on the auxiliary mounting piece 110, the auxiliary mounting piece 110 is provided with a mounting through hole 118, a first side of the auxiliary mounting piece 110 (i.e., a side away from the vehicle body structure 300) is provided with a plurality of first anti-detachment limiting structures 112, and a second side of the auxiliary mounting piece 110 opposite to the first side is provided with a plurality of second anti-detachment limiting structures 119, each first anti-detachment limiting structure 112 and each second anti-detachment limiting structure 119 are arranged around the mounting through hole 118 and are staggered with each other, that is, each first anti-detachment limiting structure 112 is located between two second anti-detachment limiting structures 119, and each second anti-detachment limiting structure 119 is located between the two first anti-detachment limiting structures 112, and a flange piece 121 of the flange nut 120 is located in the mounting through hole 118 and is confined in the second limiting space between each first anti-detachment limiting structure 112 and each second anti-detachment limiting structure 119.

[0056] In an exemplary embodiment, there are three first anti-slip limit structures 112 and three second anti-slip limit structures 119, which are evenly arranged along the circumference of the mounting through hole 118. The second anti-slip limit structure 119 has the same structure as the first anti-slip limit structure 112, but is located at a different position.

[0057] like Fig. 6E As shown, when installing the flange nut 120, the nut 122 can first be passed through the mounting hole 118 from the second side of the auxiliary mounting plate 110 to reach the first side, and then the flange plate 121 can be obliquely inserted into the second limiting space between each second anti-detachment limiting structure 119 and each first anti-detachment limiting structure 112 on the second side to prevent it from falling off, thereby realizing the assembly of the flange nut 120 and the auxiliary mounting plate 110.

[0058] In the airbag mounting assembly 100 of the third embodiment of the utility model, the flange 121 is located in the mounting through hole 118. When the airbag mounting assembly 100 is fixed to the vehicle body structure 300, the flange 121 is directly pressed against the vehicle body structure 300. Since the flange 121 and the vehicle body structure 300 are both made of metal, the risk of nut loosening due to long-term compression between the vehicle body structure 300 and the plastic can be avoided, thereby making the connection more reliable.

[0059] The airbag mounting assembly 100 of the present invention is easy to install, has a simple structure, a flexible design, and strong boundary adaptability. It can be assembled not only with studs but also with bolts. Therefore, it is suitable for bolt fixing scenarios that require the position of the airbag package.
