[0032] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0033] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “include” and “have” are used to indicate an open-ended meaning of inclusion and that there may be other elements / components / etc. in addition to the listed elements / components / etc.

[0034] This utility model embodiment provides an air curtain bracket for installation in a vehicle, such as... Figure 1-3 As shown, the air curtain bracket includes a bracket body 1 and a suspension structure 2. The suspension structure 2 includes a hook 21 and a through hole 22. The top of the bracket body 1 is detachably connected to the side panel of the vehicle, and its bottom is bent inwards to form a support part 11 for supporting the air curtain 100. The bottom of the hook 21 is fixed to the bracket body 1, and the top of the hook 21 is detachably connected to the side panel. The through hole 22 is opened in the area of ​​the bracket body 1 below the hook 21. The air curtain 100 includes a first ear piece 1001, which passes through the through hole 22 and is hung on the hook 21. In the prior art, each mounting piece is connected to the vehicle body and the air curtain 100 by bolts and anti-rotation hooks. However, due to insufficient space in the vehicle body and insufficient size of the anti-rotation hooks, the first ear piece 1001 of the air curtain 100 is prone to falling off during transportation. In this application, the bracket body 1 and the suspension structure 2 are integrally formed. The bracket body 1 is fixed to the side panel by the first bolt and the second bolt. By omitting the anti-rotation hook, the curtain airbag 100 is installed through the independently set suspension structure 2. This not only achieves the anti-rotation effect, but the suspension structure 2 only needs to be adapted to the installation position and structure of the curtain airbag 100, and is not limited by the vehicle body space. This overcomes the dimensional constraints of existing anti-rotation hooks due to limited installation space, and improves the stability of the curtain airbag 100. Specifically, as shown... Figure 1-3 The longitudinal cross-section of the bracket body 1 shown is L-shaped, with the support part 11 located at the bottom of the bracket body 1. As the air curtain 100 is placed on the side of the bracket body 1 away from the side panel, the first ear piece 1001 passes through the through hole 22 and enters between the bracket body 1 and the side panel, then moves upward and hangs upside down on the hook 21, greatly reducing the risk of the first ear piece 1001 of the air curtain 100 falling off during transportation. In addition, when the bracket body 1 is bolted to the vehicle body, the first ear piece 1001 will not rotate, which not only ensures the installation efficiency and effect of the air curtain 100, but also allows the air curtain 100 to pop out from the seam between the headliner and the interior panel of the vehicle according to the design path, ensuring that the air curtain 100 will not burst the interior panel when it is deployed, and that no fragments will fly out, thus improving the vehicle's safety performance.

[0035] In a preferred embodiment of this utility model, such as Figure 1-3The bracket body 1 shown has a first connecting ear 12, a first bolt 13, and a washer 14 on its top. The first connecting ear 12 has a first mounting hole 121, and the side has a second mounting hole corresponding to the first mounting hole 121. The first bolt 13 connects the first mounting hole 121 and the second mounting hole. The washer 14 is located on the side of the first mounting hole 121 away from the side and is connected between the bolt and the first connecting ear 12. The air curtain 100 includes a second ear piece 1002 corresponding to the first connecting ear 12, and the second ear piece 1002 is connected between the first bolt 13 and the washer 14. Figure 1-3 The first connecting ear 12 and the bracket body 1 are integrally formed. The second ear piece 1002 of the air curtain 100 is suspended between the head of the first bolt 13 and the washer 14. The shank of the bolt 13 passes through the washer 14 and the first mounting hole 121 to fix the first connecting ear 12 to the side panel. The washer 14 is a φ25mm anti-rotation washer. The anti-rotation washer can prevent the second ear piece 1002 from rotating when the first bolt 13 is assembled, and it can also cooperate with the first bolt 13 to prevent the second ear piece 1002 from falling off during transportation.

[0036] In a preferred embodiment of this utility model, such as Figure 1-3 The bracket body 1 shown is recessed towards the side wall in the area corresponding to the first connecting ear 12 to form a first groove 10. The bottom of the first connecting ear 12 is fixed to the groove wall of the first groove 10 near the side wall. By setting the first groove 10, the bracket body 1 avoids the interference area with the body sheet metal, making it easier to arrange the bracket body 1 and the air curtain 100.

[0037] In a preferred embodiment of this utility model, such as Figure 1-3 The first connecting ear 12 shown also has at least one weight reduction hole 122, which is located below the first mounting hole 121. This structure not only significantly reduces the weight of the bracket body 1 by using redundant materials in non-critical areas, but also guides stress concentration around the first mounting hole 121 through the opening, achieving the goal of "reducing weight without compromising performance".

[0038] In a preferred embodiment of this utility model, such as Figure 1-3 The first connecting ear 12 shown has a protrusion 123 on its side for engaging with the side panel. Both the vehicle side panel and the second ear piece 1002 have corresponding insertion holes for the protrusion 123. After the second ear piece 1002 is installed between the first bolt 13 and the washer 14, it can be hung on the protrusion 123. Then, the protrusion 123 is inserted into the insertion hole on the side panel, thus connecting the bracket body 1 to the side panel. Therefore, the protrusion 123 not only connects the bracket body 1 to the side panel, increasing the connection strength between the bracket body 1 and the side panel, but also limits the installation of the second ear piece 1002, improving the installation stability of the air curtain 100.

[0039] In a preferred embodiment of this utility model, such as Figure 1-3 The bracket body 1 shown also has a second connecting ear 15 on its top. The projection of the second connecting ear 15 in the direction perpendicular to the vehicle body height is L-shaped. The horizontal part of the second connecting ear 15 is fixed to the top of the bracket body 1, and the vertical part of the second connecting ear 15 is connected to the side panel. The L-shaped second connecting ear 15 can be adapted to the vehicle body space, avoiding interference with the body sheet metal, and solving the problem of difficult installation of the air curtain bracket due to vehicle body space issues. In addition, the second connecting ear 15 of this application also eliminates the anti-rotation hook. It is only connected to the side panel by the second bolt and is not connected to the air curtain 100. During the installation of the second connecting ear 15, there is no need to consider the possibility of air curtain rotation. That is, the second connecting ear 15 will not affect the air curtain 100 when connected to the vehicle body. It is only necessary to connect the first ear piece 1001 of the air curtain 100 to the independently set hook 21, making the bracket assembly more convenient and quick. In a preferred embodiment of this utility model, as Figure 1-3 The second connecting ear 15 shown has a third mounting hole 151. One of the first mounting hole 121 and the third mounting hole 151 is a circular hole, and the other is an elliptical hole. This design is because the elliptical hole is an adjustment hole that allows the part to move along the major axis of the elliptical hole, compensating for uncompensated or adaptive deformation of the side panel or the main body 1 of the bracket, and improving assembly tolerance; while the circular hole is a reference hole used to restrict the degree of freedom of the main body 1 of the bracket. In other words, this application, for the complex structure of the side panel, uses a combination of elliptical and circular holes to ensure precise positioning while allowing a certain degree of adjustment, thereby improving the adaptability of the bracket.

[0040] In a preferred embodiment of this utility model, such as Figure 1-3 The through hole 22 shown includes a straight hole segment 221 and an arc-shaped hole segment 222 connecting the two ends of the straight hole segment 221. The straight hole segment 221 extends along the length direction 1. The first ear piece 1001 passes through the straight hole segment 221 and hangs upward on the hook 21. The design is that the straight hole segment 221 located in the middle can provide a larger passage space for the first ear piece 1001, facilitating its smooth passage. The arc-shaped hole segment 222 not only facilitates the insertion of the first ear piece 1001 but also reduces friction on the first ear piece 1001. Furthermore, the arc-shaped hole segment 222 provides a larger space for the first ear piece 1001, preventing damage to the support body 1 during the inflation and deployment of the air curtain 100, thus improving the safety of the air curtain 100 during deployment.

[0041] In a preferred embodiment of this utility model, such as Figure 1-3The hook 21 shown is T-shaped. The vertical part of the hook 21 is fixed to the bracket body 1, and the horizontal part of the hook 21 is inserted into the side panel. The side panel has a mounting groove or hanging hole for installing the hook 21. The horizontal part of the hook 21 can be inserted into the corresponding mounting groove or hanging hole, so that the hook 21 is hooked onto the side panel, realizing a detachable connection between the hook 21 and the side panel. When it is necessary to replace the air curtain bracket, simply remove the horizontal part of the hook 21 from the mounting groove or hanging hole, which is convenient for installation and maintenance. In addition, the T-shape of the hook 21 can prevent the first ear piece 1001 from slipping off, improving the safety of the air curtain 100.
