[0027] Please refer to Figure 1 , Figure 2 and Figure 3 The present embodiment provides a side air curtain guide structure 100 for installation on a vehicle body sheet metal part 200. The side air curtain guide structure 100 includes a metal support plate 110 and a buffer plate 120 covering the metal support plate 110. The buffer plate 120 is a non-planar structure. The inner side of the buffer plate 120 is used to place the side air curtain 300, and the outer side of the buffer plate 120 is detachably connected to the vehicle body sheet metal part 200.

[0028] Specifically, when installing the side air curtain 300, the side air curtain guide structure 100 is first installed on the body sheet metal 200, that is, the outer side of the buffer plate 120 is detachably connected to the body sheet metal 200, and then the side air curtain 300 is placed on the inner side of the buffer plate 120 to guide and fix the side air curtain 300 through the side air curtain guide structure 100.

[0029] The side air curtain guide structure 100 of the present application is made of a metal support plate 110 externally coated with a buffer plate 120, so as to prevent the metal support from directly contacting the side air curtain 300 and damaging the side air curtain 300, thereby affecting the performance of the side air curtain 300, while ensuring stable support of the side air curtain guide structure 100.

[0030] The present application embeds a metal support plate 110 in the buffer plate 120 to ensure that the side air curtain 300 installed on the vehicle can expand toward the inside of the vehicle body after being detonated, and will not expand toward the direction of the vehicle body sheet metal 200 and drill into the gap of the vehicle body trim panel, so as to improve the protective performance of the side air curtain 300.

[0031] The side air curtain guide structure 100 provided in the present application is used to be installed on the body sheet metal 200. The side air curtain guide structure 100 includes a metal support plate 110 and a buffer plate 120 covering the metal support plate 110. The buffer plate 120 is a non-planar structure. The inner side of the buffer plate 120 is used to place the side air curtain 300. The outer side of the buffer plate 120 is detachably connected to the body sheet metal 200 to ensure that the side air curtain guide structure 100 is stably supported while preventing the metal support from directly contacting the side air curtain 300 and damaging the side air curtain, thereby improving the stability and protection performance of the side air curtain 300.

[0032] In a feasible embodiment of the present application, Figure 1 , Figure 2 and Figure 3 As shown, the buffer plate 120 includes a first connecting plate 121, a first supporting plate 122 and a second supporting plate 123 connected in sequence, the first connecting plate 121 and the first supporting plate 122 are arranged at a preset angle, and the side air curtain guide structure 100 is connected to the body sheet metal 200 through the first connecting plate 121.

[0033] Specifically, when installing the side air curtain 300, the side air curtain guide structure 100 is first installed on the body sheet metal 200, that is, the side air curtain guide structure 100 is detachably connected to the body sheet metal 200 through the first connecting plate 121, and then the side air curtain 300 is placed between the first support plate 122 and the second support plate 123 to achieve stable installation of the side air curtain 300.

[0034] The first connecting plate 121 and the first supporting plate 122 are arranged at a preset angle so that the side air curtain guide structure 100 can better fit the structure of the vehicle body sheet metal 200, so that after the side air curtain guide structure 100 is installed, the side air curtain 300 in the side air curtain guide structure 100 can be more conveniently installed and fixed.

[0035] In a feasible embodiment of the present application, Figure 1 , Figure 2 and Figure 3As shown, the metal support plate 110 is located inside the first connecting plate 121 and the first support plate 122 .

[0036] Specifically, the metal support plate 110 is embedded between the first connecting plate 121 and the first supporting plate 122. The first connecting plate 121 and the first supporting plate 122 are arranged close to the body sheet metal 200. In the present application, the metal support plate 110 is embedded inside the side of the buffer plate 120 close to the body sheet metal 200, so that during the explosion of the side air curtain 300, the side air curtain 300 will not expand toward the body sheet metal 200. The side air curtain guide structure 100 is used to ensure that the side air curtain 300 expands toward the inside of the vehicle after the explosion, so as to ensure that the side air curtain 300 provides stable support for the passengers in the vehicle after the explosion.

[0037] It is understandable that the second metal support plate 110 can also be embedded in the second support plate 123. The metal support plate 110 inside the first connecting plate 121 and the first support plate 122 is not connected to the second metal support plate 110 inside the second support plate 123. During the explosion of the side air curtain 300, the impact force will cause the second support plate 123 to move away from the first support plate 122, which will exert a large impact force on the second support plate 123. The present application embeds the second metal support plate 110 inside the second support plate 123 to ensure the overall strength of the second support plate 123 and avoid damage to the second support plate 123 due to impact force.

[0038] In a feasible embodiment of the present application, Figure 1 , Figure 2 and Figure 3 As shown, the first support plate 122 and the second support plate 123 together form a V-shaped structure for placing the side air curtain 300 .

[0039] Specifically, the first support plate 122 and the second support plate 123 are combined to form a V-shaped structure. When installing the side air curtain 300, the side air curtain guide structure 100 is first installed on the body sheet metal 200, that is, the side air curtain guide structure 100 is detachably connected to the body sheet metal 200 through the first connecting plate 121, and then the side air curtain 300 is placed in the V-shaped structure formed by the first support plate 122 and the second support plate 123 to achieve stable installation of the side air curtain 300.

[0040] In a feasible embodiment of the present application, Figure 1 , Figure 2 and Figure 3 As shown, a groove 124 is provided at the outer bending portion of the V-shaped structure, and the groove 124 extends along the connecting line between the first support plate 122 and the second support plate 123 .

[0041] Specifically, during the explosion of the side air curtain 300, the impact force will cause the second support plate 123 to move away from the first support plate 122. A groove 124 is provided at the outer bend of the V-shaped structure so that the second support plate 123 can be bent at a certain angle relative to the first support plate 122 after being subjected to the impact force, so that the first support plate 122 and the second support plate 123 of the V-shaped structure open to an obtuse angle, so that the side air curtain 300 expands in a direction away from the vehicle body sheet metal 200.

[0042] Furthermore, it is necessary to set a groove 124 so that after the second support plate 123 is bent relative to the first support plate 122, the first support plate 122 and the second support plate 123 are still set at an obtuse angle. After the groove 124 is squeezed, the two side walls of the groove 124 are abutted against each other, that is, the second support plate 123 can be supported after being bent to a certain angle, so as to ensure that the bent second support plate 123 still has a guiding effect on the expansion direction of the side air curtain 300.

[0043] Furthermore, a plurality of grooves 124 are provided extending along the connection line between the first support plate 122 and the second support plate 123 , so that during the explosion of the side air curtain 300 , the second support plate 123 can be opened to a preset angle relative to the first support plate 122 .

[0044] It should be noted that the shape of the groove 124 is not limited. The groove 124 can be an arc-shaped groove or a V-shaped groove. The distance and depth of the two side plates of the groove can be adjusted to achieve an obtuse angle between the first support plate 122 and the second support plate 123 after the two side walls of the groove 124 are abutted against each other.

[0045] In a feasible embodiment of the present application, Figure 1 , Figure 2 and Figure 3 As shown, the end of the metal support plate 110 located inside the first support plate 122 is bent outward.

[0046] Specifically, during the explosion of the side air curtain 300, the impact force will exert pressure on the first connecting plate 121, the first support plate 122 and the second support plate 123, bending the end of the metal support plate 110 located in the first support plate 122 outward to prevent the first support plate 122 from being squeezed outward under pressure. The end of the metal support plate 110 located in the first support plate 122 pierces the first support plate 122, damaging the side air curtain guide structure 100, so as to ensure the stability of the side air curtain guide structure 100.

[0047] In a feasible embodiment of the present application, Figure 1 , Figure 2 and Figure 3 As shown, a clamping portion 125 is provided on the outer side of the connection between the first connecting plate 121 and the first supporting plate 122 , and the clamping portion 125 is clamped with the vehicle body sheet metal component 200 .

[0048] A connecting hole is provided in the middle of the first connecting plate 121 , and the connecting member 126 passes through the connecting hole to connect with the vehicle body sheet metal member 200 .

[0049] Specifically, the present application provides a clamping portion 125 on the outer side of the connection between the first connecting plate 121 and the first supporting plate 122, and provides a connecting hole in the middle of the first connecting plate 121, and connects the side air curtain guide structure 100 and the vehicle body sheet metal 200 through the two connecting positions of the clamping portion 125 and the connecting hole to ensure the stable installation of the side air curtain guide structure 100.

[0050] It should be noted that the clamping portion 125 extends along the connecting line between the first connecting plate 121 and the first supporting plate 122, and a plurality of connecting holes are provided along the connecting line between the first connecting plate 121 and the first supporting plate 122 to ensure the stable installation of the side air curtain guide structure 100, thereby ensuring the stable fixation of the side air curtain 300 by the side air curtain guide structure 100.

[0051] When installing the side air curtain 300, first install the side air curtain guide structure 100 on the body sheet metal 200, that is, clamp the connecting part with the body sheet metal 200, and then connect it to the body sheet metal 200 through the connecting hole through the connecting piece 126 to complete the connection between the body sheet metal 200 and the side air curtain guide structure 100, and then place the side air curtain 300 in the V-shaped structure formed by the first support plate 122 and the second support plate 123 to achieve stable installation of the side air curtain 300.

[0052] In a feasible embodiment of the present application, Figure 1 , Figure 2 and Figure 3 As shown, the buffer plate 120 is integrally injection molded.

[0053] The buffer plate 120 of the present application is integrally injection molded, that is, the side air curtain guide structure 100 is formed on the metal support plate 110 by an extrusion process to complete the assembly of the side air curtain guide structure 100. When using the side air curtain guide structure 100 of the present application, the side air curtain guide structure 100 of a suitable length can be cut according to the required length.

[0054] It should be noted that the material of the buffer plate 120 is a soft plastic material such as TPO, so that the buffer plate 120 has a certain elasticity.

[0055] The embodiment of the present application also discloses a side air curtain assembly, including a side air curtain 300 and the side air curtain guide structure 100 in the aforementioned embodiment, wherein the side air curtain 300 is arranged inside the side air curtain guide structure 100. The side air curtain assembly includes the same structure and beneficial effects as the side air curtain guide structure 100 in the aforementioned embodiment. The structure and beneficial effects of the side air curtain guide structure 100 have been described in detail in the aforementioned embodiment and will not be repeated here.
