[0032] See Figures 1 to 6 This utility model provides a side curtain airbag generator fixing device, including a mounting part 1 and a guide part 2. The mounting part 1 includes a first surface 11 and a second surface 12 facing each other, and the first surface 11 is used to fix the generator 7. The mounting part 1 is provided with a snap-fit ​​structure 4 and a threaded connection structure 5 for connecting with the vehicle body 8. The guide part 2 is connected to the mounting part 1 and is used to guide the deployment of the side curtain airbag. The guide part 2 includes a third surface 21 and a fourth surface 22 facing each other, the third surface 21 and the first surface 11 are located on the same side, and the fourth surface 22 and the second surface 12 are located on the same side.

[0033] The side curtain airbag generator fixing device of this embodiment includes a mounting part 1 and a guide part 2. The mounting part 1 includes a first surface 11 and a second surface 12 facing each other. The first surface 11 is used to fix the generator 7. The mounting part 1 is provided with a snap-fit ​​structure 4 and a threaded connection structure 5 for connecting with the vehicle body 8. The guide part 2 is connected to the mounting part 1 and is used to guide the deployment of the side curtain airbag. The mounting part 1, as a fixing bracket for the generator 7, is connected to the guide part 2, which serves as a B-pillar guide bracket, thus reducing the weight of the side curtain airbag module and reducing the space occupied on the side of the vehicle body 8. The connection between the mounting part 1 and the vehicle body 8 via the snap-fit ​​structure 4 and the threaded connection structure 5 simplifies the assembly steps.

[0034] See Figure 6 When the mounting part 1 is connected to the body 8, the second surface 12 is located on the side closer to the body 8. The snap-fit ​​structure 4 includes a snap hook, which engages with a snap hole 81 on the body 8 to snap the mounting part 1 to the body 8. The snap-fit ​​structure 4 is located on the second surface 12 of the mounting part 1. The threaded connection structure 5 may include a fixing hole 52, through which a bolt 53 passes and engages with a threaded hole 82 on the body 8 to thread the mounting part 1 to the body 8. The snap-fit ​​structure 4 is not affected by the retainer fixed to the mounting part 1, making the connection convenient. The threaded connection structure 5 can improve the connection strength between the mounting part 1 and the body 8. The snap-fit ​​structure 4 and the threaded connection structure 5 cooperate to facilitate the connection between the mounting part 1 and the body 8, and the connection is firm.

[0035] In some embodiments, see Figure 2The hook can be a T-shaped hook. The hook includes a hook shank 41 and a hook body 42. One end of the hook shank 41 is connected to the mounting part 1, and the other end is connected to the middle of the hook body 42. The hook body 42 is perpendicular to the hook shank 41, and the hook body 42 and hook shank 41 are located on the same plane. During connection, both ends of the hook body 42 engage with the edges of the holes 81 on the vehicle body 8. The hook shank 41 is substantially perpendicular to the second surface 12.

[0036] In some embodiments, see Figure 2 The hook body 42 has protrusions 421 extending toward the second surface 12 at both ends, and there is a gap between the protrusions 421 and the hook handle 41. By providing protrusions 421 on the hook body 42 and forming a gap between the protrusions 421 and the hook handle 41, the stability of the hook engagement with the vehicle body can be improved, and the overall connection between the mounting part 1 and the vehicle body can be made more secure.

[0037] In some embodiments, the mounting part 1 has a groove on the first surface 11 for accommodating the generator 7. The groove can limit the generator 7 and improve the stability of the connection between the generator 7 and the mounting part 1.

[0038] In some embodiments, see Figure 1 and Figure 2 The mounting part 1 includes a first curved plate. The first curved plate has a concave arc surface on its first surface 11 for accommodating the generator 7, and a convex arc surface on its second surface 12. The concave arc surface formed on the first surface 11 of the first curved plate serves as a groove for accommodating the generator 7. The mounting part 1 can be formed by mechanically machining a sheet metal to create a shape with one side being a concave arc surface and the other side being a convex arc surface. This facilitates processing and saves materials.

[0039] In some embodiments, see Figure 1 and Figure 2 The guide section 2 includes a second curved plate, which has a concave arc surface on a third surface 21 and a convex arc surface on a fourth surface 22. The guide section 2 can be formed by machining a sheet metal to create a shape with one side being a concave arc surface and the other a convex arc surface. The concave arc surface on the third surface 21 and the convex arc surface on the fourth surface 22 of the guide section 2 better guides the deployment of the side air curtain. The curved plate shape of the guide section 2 facilitates processing and saves material.

[0040] In some embodiments, see Figure 2 The edge of the guide section 2 is bent towards the fourth surface 22 to form a folded edge 23. The folded edge 23 on the edge of the guide section 2 can enhance the strength of the guide section 2. When the side air curtain of the generator 7 is detonated and deployed, the guide section 2 is less likely to deform, reducing the risk of the side air curtain being torn or not deploying smoothly.

[0041] In some embodiments, see Figure 1 and Figure 2The mounting part 1 and the guide part 2 are connected by a connecting part 3. The connecting part 3 includes a fifth surface 31 and a sixth surface 32 facing each other. The fifth surface 31 is located on the same side as the first surface 11, and the sixth surface 32 is located on the same side as the second surface 12. The connecting part 3 forms a convex arc surface on the fifth surface 31 and a concave arc surface on the sixth surface 32. One side of the connecting part 3 forms a convex arc surface, and the other side forms a concave arc surface. The connecting part 3 can be obtained by bending the sheet metal between the mounting part 1 and the guide part 2 through mechanical processing. The mounting part 1, the connecting part 3, and the guide part 2 are all bent, and the whole is wavy.

[0042] In some embodiments, the side curtain air generator fixing device of this utility model is an integral structure. In an exemplary embodiment, the side curtain air generator fixing device of this utility model can be formed by bending a first plate, a second plate, and a third plate connected in sequence. The first plate is bent to form a shape with one concave arc surface and the other convex arc surface, resulting in a mounting part 1. The second plate is bent to form a shape with one convex arc surface and the other concave arc surface, resulting in a connecting part 3. The concave arc surface of the mounting part 1 and the convex arc surface of the connecting part 3 are on the same side. The third plate is bent to form a shape with one concave arc surface and the other convex arc surface, resulting in a guide part 2. The concave arc surface of the guide part 2 and the concave arc surface of the mounting part 1 are on the same side.

[0043] The snap-fit ​​structure 4 and the threaded connection structure 5 are distributed along the length of the mounting part 1, and the snap-fit ​​structure 4 and the threaded connection structure 5 can be respectively located near both ends of the mounting part 1. In a specific implementation, the snap-fit ​​structure 4 can be located at one end of the mounting part 1, and the threaded connection structure 5 can be located at the other end of the mounting part 1.

[0044] In some embodiments, see Figure 3 and Figure 4 One end of the mounting part 1 is bent to form a fixing part 51 protruding towards the second surface 12, and a fixing hole 52 is provided in the fixing part 51. One end of the mounting part 1 is bent to form a fixing part 51 protruding towards the second surface 12, and a bolt 53 passes through the fixing hole 52 on the fixing part 51 and is threaded to the body 8. The other end is engaged with the body 8 by a hook. The fixing part 51 and the hook can be of basically the same size protruding from the second surface 12, so that the mounting part 1 can be fixed to the body 8 in a basically parallel manner.

[0045] In some embodiments, see Figure 2 , Figure 3 and Figure 4The mounting part 1 has a first window 13, and a first tongue is connected to one side of the first window 13. The first tongue is bent toward the second surface 12 to form a hook. In a specific implementation, the first tongue can be formed on the mounting part 1 by stamping or other methods, and the hook can be formed by bending the first tongue, and the first window 13 can be formed at the original position of the first tongue on the mounting part 1. This can save materials and processes, eliminate the need for additional welding of the hook, and make the side curtain air generator fixing device of this utility model embodiment an integral structure.

[0046] In some embodiments, see Figures 1 to 3 The mounting part 1 is provided with an arc-shaped plate 6 protruding from the second surface 12, and the arc-shaped plate 6 is located between the hook and the fixing hole 52. When the side curtain air generator fixing device of this embodiment is fixed to the vehicle body 8, the arc-shaped plate 6 abuts against the vehicle body 8, and cooperates with the snap-fit ​​structure 4 and the threaded connection structure 5, which can improve the stability of the connection between the side curtain air generator fixing device and the vehicle body 8. In addition, the arc-shaped plate 6 has a certain elastic deformation capacity, which improves the stability of the connection between the side curtain air generator fixing device and the vehicle body 8.

[0047] In some embodiments, see Figure 2 and Figure 4 The mounting part 1 has a second window 14, and the two ends of the arc-shaped plate 6 are respectively connected to the opposite sides of the second window 14. In a specific implementation, the arc-shaped plate 6 can be formed by stamping or other methods, and the second window 14 can be formed in the original position of the mounting part 1. This can save materials and processes, eliminate the need to weld the arc-shaped plate 6 separately, and make the side curtain air generator fixing device of this utility model embodiment an integral structure.

[0048] In some embodiments, see Figure 5 The generator 7 can be fixed to the mounting part 1 by means of clamp 9, see 2. Figure 3 and Figure 4 The mounting part 1 has a limiting structure 15, which is used to axially limit the clamp 9. The limiting structure 15 can prevent the clamp 9 from sliding relative to the mounting part 1 along the axial direction.

[0049] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The limiting structure 15 includes at least one of a limiting groove 151 and a limiting protrusion 152.

[0050] See Figure 2 , Figure 3 and Figure 4A limiting groove 151 is provided circumferentially on the second surface 12. In a specific implementation, the limiting groove 151 is formed circumferentially on the second surface 12, and the clamp 9 is at least partially embedded in the limiting groove 151 to prevent the clamp 9 from sliding. The limiting groove 151 on the second surface 12 can be continuous or discontinuous. For example, the limiting groove 151 can be provided near both sides of the second surface 12. Alternatively, the limiting groove 151 can be continuously formed from one side to the other on the second surface 12. The limiting groove 151 can be formed by milling or other methods.

[0051] See Figure 2 , Figure 3 and Figure 4 The limiting protrusion 152 may be located on the side of the mounting portion 1 near the guide portion 2 and / or away from the guide portion 2. The limiting protrusion 152 may be located on one or both sides of the mounting portion 1, so that the limiting protrusion 152 and the mounting portion 1 are an integral structure without the need for additional welding.

[0052] In some embodiments, the limiting protrusion 152 may also cooperate with the connecting portion 3, and a space for accommodating the clamp 9 is formed between the limiting protrusion 152 and the connecting portion 3. The clamp 9 is disposed in the space between the limiting protrusion 152 and the connecting portion 3.
