[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] like Figure 1As shown, the curtain airbag buckle 100 of the present embodiment includes a first connecting structure 1, a second connecting structure 2, and a tether 3. For example, the curtain airbag buckle 100 can be made of plastic, and the first connecting structure 1, the second connecting structure 2, and the tether 3 can be integrally formed by injection molding. The tether 3 can be elongated and bendable. The first connecting structure 1 can be located at one end of the tether 3, and the second connecting structure 2 can be located at the other end.

[0037] During assembly, the first connecting structure 1 can be assembled and fixed with the vehicle's sheet metal 200, the interior decoration part can be an interior panel arranged on the inner side of the sheet metal 200, and the second connecting structure 2 and the tether 3 can pass through the vehicle's interior decoration part. When the air curtain is not detonated, the second connecting structure 2 and the interior panel are loosely assembled, that is, there is no direct limiting effect between the second connecting structure 2 and the interior panel.

[0038] When the air curtain is detonated, the interior panel will detach from the sheet metal 200. At this time, the interior panel will move along the tether 3 to the second connecting structure 2. The limiting constraint of the second connecting structure 2 can prevent the interior panel from completely detaching, thereby achieving a protective effect.

[0039] The first connecting structure 1 is provided with a disc 11 and a column 12 . The disc 11 is connected between the column 12 and the lacing 3 . The column 12 is provided with a first buckle 13 for snap-fitting and assembling with the sheet metal 200 . The first buckle 13 is connected to the disc 11 .

[0040] For example, Figure 1 As shown, the disc body 11 can be generally an elliptical disc-shaped structure. The column 12 can be integrally formed on one side of the disc body 11 via injection molding, with the axial direction of the column 12 generally perpendicular to the plane of the disc body 11. The lacing 3 can also be integrally formed on the other side of the disc body 11 via injection molding. When the first connecting structure 1 is mounted and fixed to the sheet metal 200, the disc body 11 can be aligned with the sheet metal 200, thereby enhancing the assembly limit effect and also serving as a rotation prevention function.

[0041] The first clip 13 can be integrally formed on the column 12 by injection molding. The first clip 13 can be arranged to extend axially along the column 12, and the end of the first clip 13 facing the disk body 11 can be directly connected to the disk body 11. The sheet metal 200 can be provided with an assembly hole. During assembly, the column 12 and a portion of the first clip 13 can be passed through the assembly hole. The sheet metal 200 can then be fastened and secured by means of structures such as the slot 133 on the first clip 13.

[0042] In the air curtain buckle 100 of the embodiment of the present invention, the first buckle 13 is connected to the column 12 and the disc 11 at the same time, wherein the connection between the first buckle 13 and the disc 11 can limit the first buckle 13 from being easily deformed or deforming too much, thereby avoiding the problem in the prior art that the first buckle 13 is only connected to the column 12 and is easily detached from the sheet metal 200 when detonated due to the easy deformation of the first buckle 13, thereby increasing the holding force of the first buckle 13 and ensuring the structural stability of the assembly.

[0043] In some embodiments, the column 12 is provided with an opening 121, the first clip 13 is provided in the opening 121 and is arranged in the side wall gap opposite to the opening 121 in the circumferential direction of the column 12, one end of the first clip 13 is connected to the end of the column 12 away from the disk body 11, and the other end of the first clip 13 is connected to the disk body 11.

[0044] For example, Figure 2 As shown, the opening 121 can be a long hole, the column 12 can be a circular column, the opening 121 can be provided in the column 12 and extended along the axial direction of the column 12, the first clip 13 can be provided in the opening 121, and the first clip 13 and the two long side walls of the opening 121 that are arranged opposite to each other in the circumferential direction of the column 12 are spaced apart. Thus, the first clip 13 can have a certain elastic deformation ability, thereby facilitating the assembly and fixation of the first clip 13 and the sheet metal 200.

[0045] The first buckle 13 can generally extend along the axial direction of the column 12. One end of the first buckle 13 along the extension direction can be connected to the free end of the column 12, and the other end of the first buckle 13 along the extension direction can be connected to the disc 11. During use, the connection between the disc 11 and the first buckle 13 can limit the amount of deformation of the first buckle 13 toward the inside of the column 12, thereby enhancing the assembly retention force of the first buckle 13.

[0046] In some embodiments, as Figure 2 As shown, the first buckle 13 includes a first protrusion 131 , a second protrusion 132 and a root 135 .

[0047] The first protrusion 131 and the second protrusion 132 are arranged at intervals in the axial direction of the column 12 and are provided on the outside of the column 12. The second protrusion 132 is provided adjacent to the disk body 11, wherein the thickness dimension of the first protrusion 131 in the radial direction of the column 12 can gradually increase along the direction approaching the disk body 11, thereby facilitating the first protrusion 131 to pass through the assembly hole of the sheet metal 200, and the second protrusion 132 can be in the shape of a long strip, and the second protrusion 132 can extend along the radial direction of the column 12.

[0048] A slot 133 for engaging with the sheet metal 200 is formed between the first protrusion 131 and the second protrusion 132. Figure 2 As shown, the slot 133 can be roughly a rectangular slot. During assembly, the first protrusion 131 can pass through the assembly hole of the sheet metal 200, and the sheet metal 200 on the surrounding side of the assembly hole can be clamped and limited between the first protrusion 131 and the second protrusion 132, thereby facilitating the assembly and fixation of the sheet metal 200 and the first connecting structure 1.

[0049] The root 135 is connected between the second protrusion 132 and the disk body 11. Figure 2 As shown, the root 135 can be roughly in the shape of a rectangular parallelepiped, and the root 135 can be integrally formed between the above-mentioned second protrusion 132 and the disk body 11 by injection molding, thereby realizing the connection limitation between the first clip 13 and the disk body 11, avoiding the problem that the first clip 13 is easy to deform and causes poor assembly retention force.

[0050] In some embodiments, the first buckle 13 includes a connecting portion 134 opposite to the slot 133 in the radial direction of the column 12 , the connecting portion 134 is connected between the first protrusion 131 and the second protrusion 132 , and the thickness of the root 135 is smaller than the thickness of the connecting portion 134 .

[0051] For example, Figure 2 As shown, the thickness dimension of the connecting portion 134 can be dimension L1, and the thickness dimension of the root 135 can be dimension L2. Dimension L1 is smaller than dimension L2. Thus, the root 135 is easier to deform than other parts of the first clip 13, thereby meeting the deformation requirements of the first clip 13 when assembled with the sheet metal 200.

[0052] In some embodiments, the column 12 is provided with an inner hole 122, and the connecting portion 134 is used to form a wall surface of the inner hole 122 and the root portion 135 is used to form a wall surface of the inner hole 122 that is flush. Figure 2 As shown, the column 12 can be generally annular and cylindrical, and the internal space of the column 12 forms an inner hole 122 , and the opening 121 on the column 12 is connected to the inner hole 122 .

[0053] The above-mentioned first protrusion 131, connecting portion 134, second protrusion 132, and root 135 can be arranged in sequence along the direction close to the disk body 11, and the wall surface of the hole wall of the inner hole 122 formed by the first protrusion 131, the wall surface of the hole wall of the inner hole 122 formed by the connecting portion 134, the wall surface of the hole wall of the inner hole 122 formed by the second protrusion 132, and the wall surface of the hole wall of the inner hole 122 formed by the root 135 can all be arranged flush, that is, located on the same curved surface.

[0054] Thus, the root portion 135 can be positioned closer to the axis of the column 12 relative to the connecting portion 134 , thereby increasing the inward swinging amount of the first buckle 13 and further meeting the assembly requirements.

[0055] In some embodiments, the thickness of the root portion 135 in the radial direction of the column 12 is 0.5 mm to 1 mm. Figure 2 As shown, the dimension L2 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc. The thickness of the root 135 within this value range satisfies both the need to limit the first buckle 13 and the need to allow the first buckle 13 to swing and deform.

[0056] In some embodiments, the tray 11 includes a plate portion 111 and a skirt portion 112, wherein the plate portion 111 is connected between the root portion 135 and the lace 3, for example, Figure 2 As shown, the plate portion 111 can be generally flat, the root portion 135 and the tie 3 can be arranged relative to each other in the thickness direction of the plate portion 111, the root portion 135 can be integrally formed and connected to one side of the plate portion 111, and the tie 3 can be integrally formed and connected to the other side of the plate portion 111.

[0057] The skirt 112 is provided on the plate 111 and extends closed along the circumference of the plate 111. The skirt 112 is provided on the side of the plate 111 away from the lace 3. The root 135 is located inside the skirt 112. The skirt 112 is provided with a slot 113 for the second protrusion to extend out.

[0058] For example, Figure 2 As shown, the shape of the skirt 112 can be adapted to the shape of the plate 111, and both the plate 111 and the skirt 112 can be roughly runway-shaped, wherein the skirt 112 can be integrally formed on the outer peripheral side of the plate 111 and extend along the circumference of the plate 111 to close into a circle, and the side of the skirt 112 away from the plate 111 can be folded toward the outside of the column 12, and the skirt 112 as a whole can be wrapped around the outer peripheral side of the root 135.

[0059] When the sheet metal 200 is fastened and fixed with the first buckle 13 , the skirt 112 can fit and stop against the sheet metal 200 , thereby enhancing the limiting effect and ensuring the structural stability of the assembly.

[0060] like Figure 2 As shown, the skirt 112 may be provided with a slot 113, which may be a rectangular slot and extends through the skirt 112 in the radial direction of the column 12. The second protrusion 132 may extend from the slot 113 to the outside of the skirt 112. When the first connecting structure 1 needs to be disassembled from the sheet metal 200, the second protrusion 132 can be pressed inward to drive the first buckle 13 to swing inward, thereby allowing the sheet metal 200 to be disengaged from the slot 133, thereby facilitating the disassembly of the sheet metal 200 and the first connecting structure 1.

[0061] In some embodiments, two first clips 13 can be provided on the column 12, and the two first clips 13 can be arranged opposite to each other in the radial direction of the column 12. The two first clips 13 can be connected to the disk body 11 through the above-mentioned root 135, and the second protrusions 132 of the two first clips 13 can extend from the corresponding grooves 113.

[0062] In some embodiments, the second connecting structure 2 includes a first hook 21 and a second hook 22 arranged at intervals in the extension direction of the strap 3, and the interior decoration includes a limit plate 301 for blocking and limiting the second connecting structure 2, and the distance between the first hook 21 and the second hook 22 is not less than the thickness of the limit plate 301.

[0063] For example, Figure 1 As shown, two first hooks 21 and two second hooks 22 can be provided, and the two first hooks 21 and the two second hooks 22 can be arranged in an eight-shaped pattern, wherein the spacing between the two first hooks 21 can gradually decrease in the direction approaching the first connecting structure 1, and the two first hooks 21 can be arranged in a mirror-symmetrical manner. The spacing between the two second hooks 22 can gradually decrease in the direction away from the first connecting structure 1, and the two second hooks 22 can be arranged in a mirror-symmetrical manner.

[0064] like Figure 3 and Figure 4 As shown, the stop plate 301 can be provided with a through-hole, which can be a long hole, for the second connecting structure 2 and the lace 3 to pass through. During assembly, the two second hooks 22 can first be passed through the through-hole. During assembly, the two second hooks 22 can be pressed inward and passed through the through-hole. The second connecting structure can then be rotated 290 degrees, thereby allowing the two first hooks 21 to pass through the through-hole. Finally, the lace 3 can be passed through the through-hole to a certain length.

[0065] When the air curtain explodes, the limit plate 301 will move toward the second connecting structure 2. When it moves to the second connecting structure 2, the two first hooks 21 and the two second hooks 22 can both stop and limit the limit plate 301, thereby avoiding the situation where the limit plate 301 is completely detached.

[0066] like Figure 1 As shown, the distance between the first hook portion 21 and the second hook portion 22 can be a dimension L, such as Figure 3 As shown, the thickness dimension of the limit plate 301 can be dimension M, and dimension L is larger than dimension M. Thus, sufficient gap can be reserved between the first hook 21 and the second hook 22, thereby facilitating the rotation of the position between the first hook 21 and the second hook 22 during assembly and disassembly, thereby improving the convenience of installation and disassembly.

[0067] In some embodiments, the distance between the first hook portion 21 and the second hook portion 22 gradually decreases in the direction away from the lace 3, for example, Figure 1 As shown, the first hook 21 and the second hook 22 on the same side of the strap 3 are also generally arranged in an eight-shape. The free end of the first hook 21 is the end of the first hook 21 away from the strap 3, and the free end of the second hook 22 is the end of the second hook 22 away from the strap 3. The distance L between the free end of the first hook 21 and the free end of the second hook 22 is less than the thickness dimension M of the limiting plate 301.

[0068] In some embodiments, the thickness of the limiting plate 301 is 2.5 mm to 3 mm, and the distance between the first hook portion 21 and the second hook portion 22 is 3 mm to 3.5 mm. For example, the thickness M of the limiting plate 301 can be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, etc. The distance L between the first hook portion 21 and the second hook portion 22 can be 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, etc.

[0069] The following describes a vehicle according to an embodiment of the present invention.

[0070] The vehicle of the embodiment of the present invention includes an air curtain buckle, which can be the air curtain buckle 100 described in any of the above embodiments. The vehicle can be a car, SUV, bus or other vehicle.

[0071] In some embodiments, the vehicle includes a connecting column for connecting the roof and the body, and the connecting column can be an A-pillar, a B-pillar, etc. of the vehicle, and the connecting column includes a sheet metal 200 and an interior trim, such as Figures 3 to 5 As shown, the interior decoration part is provided with a mounting seat 300, which is a doghouse structure. The mounting seat 300 can be integrally formed on the interior decoration part by injection molding.

[0072] The first connecting structure 1 is secured to the sheet metal 200 and the mounting base 300 by snapping. The tether 3 passes through the mounting base 300. The second connecting structure 2 is used to constrain the mounting base 300 during detonation. For example, the aforementioned limiting plate 301 can be integrally formed with the mounting base 300. The first connecting structure 1 also includes a second buckle 14. During assembly, when the second connecting structure 2 and the tether 3 pass through the limiting plate 301, the two second buckles 14 of the first connecting structure 1 can be secured by snapping with the limiting plate 301.

[0073] When the air curtain is detonated, the two second buckles 14 will first disengage from the limit plate 301. When the limit plate 301 moves along the strap 3 to the second connecting structure 2, the second connecting structure 2 will stop and limit with the limit plate 301, thereby avoiding the complete detachment of the interior parts.

[0074] Although the above embodiments have been shown and described, it is understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments made by ordinary technicians in this field are all within the scope of protection of the present invention.
