[0033] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.
[0034] like Figure 1-Figure 2 As shown, according to a preferred embodiment of the present invention, the automobile sunroof reinforcement frame is a hemp fiber hot-pressed plate and includes a frame body 1 and an extension ring 2, wherein the frame body 1 is in the shape of a rectangular frame and is framed on a sunroof opening opened on the automobile roof (not shown), and the extension ring 2 extends outward from the bottom of the frame body 1 to fit with the automobile roof. It should be understood that the frame body 1 and the extension ring 2 are integrally formed here, and they are artificially divided only for the convenience of description. The automobile sunroof reinforcement frame of the present invention is formed of a hemp fiber hot-pressed plate. Compared with a metal reinforcement frame, it is lighter, more low-carbon and environmentally friendly, and can be combined with surrounding parts to increase the required shape.
[0035] like Figure 3As shown, the automobile sunroof reinforcement frame according to this embodiment is composed of a first side wall 10, a second side wall 20, a third side wall 30, and a fourth side wall 40 connected end to end. The four connection points 50 of adjacent side walls 10, 20, 30, and 40 are located at the corners of the rectangular frame to fully utilize the material. It should be understood that this division method is only for example and not for limitation. In another preferred embodiment, the four connection points 50 of adjacent side walls are directly set on the longer side wall, such as Figure 4 As shown, the first side wall 10 and the third side wall 30 are in a square bracket shape. In another preferred embodiment, the connection points 50 are reduced to two, and it is also feasible to locate them at the diagonal corners of the rectangular frame, such as Figure 5 As shown, at this time, the first side wall 10 and the second side wall 20 are integrally formed into an L-shape, and the third side wall 30 and the fourth side wall 40 are integrally formed into another L-shape.
[0036] Back to Figure 3 Since the settings of the four connection points 50 are basically the same, the following description will be made by taking the connection between the first side wall 10 and the second side wall 20 as an example. Figure 6 shown.
[0037] like Figure 7 and Figure 8 As shown, the end of the first side wall 10 has a step portion 110 extending in the same direction, which is convex outward relative to the inner surface 10a, that is, offset radially outward. Figure 9 and Figure 10 As shown, the end of the second side wall 20 has a lap portion 210 which does not have any step offset. Figure 11 As shown, the step portion 110 is covered and connected to the overlapping portion 210. In particular, the inner surface 10a of the first side wall 10 and the inner surface 20a of the second side wall 20 are kept flush.
[0038] like Figure 12 As shown, the step portion 110 is connected to the overlap portion 210 using glue. It should be understood that the glue connection here is only an example and not a limitation. For example, it is also feasible to achieve connection by welding, and it is also feasible to achieve splicing by riveting with rivets 500, such as Figure 13 Compared to the snap-on splicing method of, for example, a plastic frame, the splicing method of the present invention is more flexible and simple, and does not require a complex connection structure.
[0039] Back to Figure 1-Figure 2 The frame 1 has a plurality of laterally protruding bosses 1a, which are mounted in the concave track B1 of the sunroof mechanism B. Figure 14As shown. The automobile sunroof reinforcement frame of the present invention is made of hemp fiber hot-pressed board. Since the hemp fiber hot-pressed board has good elongation, the boss 1a can be integrally formed during the hot-pressing process of forming the automobile sunroof reinforcement frame, which is low in cost. In this embodiment, the boss 1a is arranged on the first side wall 10, the second side wall 20 and the fourth side wall 40, see Figure 1 and Figure 3 The frame body 1 of the third side wall 30 does not have a boss. It should be understood that the arrangement of the boss 1a is merely an example and not a limitation, and can also be arranged on the third side wall 30 as needed. In particular, the boss 1a is arranged on at least two sides of the frame body 1 parallel to the vehicle door.
[0040] like Figure 1-Figure 2 and Figure 14 As shown, the extension ring 2 has protruding reinforcement ribs 2a. Figure 15 As shown, when the curtain airbag 60 deploys, it directly strikes the edge of the extension ring 2, causing deformation. The extension ring 2 rotates around its root 2b, with a deformation amount of ΔL1. By providing the reinforcing rib 2a on the extension ring 2, when the curtain airbag 60 deploys, the curtain airbag 60 directly strikes the edge of the extension ring 2, causing deformation. The extension ring 2 rotates around the root of the reinforcing rib 2a, and the deformation amount ΔL2 is significantly smaller than the deformation amount ΔL1. Figure 16 As shown. The automobile sunroof reinforcement frame of the present invention is made of hemp fiber hot-pressed board. Since the hemp fiber hot-pressed board has good elongation, the reinforcement ribs 2a can be integrally formed during the hot-pressing process of forming the automobile sunroof reinforcement frame, which is low in cost. In this embodiment, the reinforcement ribs 2a are generally arranged on the second side wall 20, the third side wall 30 and the fourth side wall 40, see Figure 1 and Figure 3 It should be understood that the arrangement of the reinforcing rib 2a is only an example and not a limitation, and it may not be arranged on the third side wall 30, but may be arranged on the first side wall 10, such as Figure 7 As shown, the step portion 110 of the first side wall 10 has a small section of reinforcing rib 2a, as shown in FIG. Figure 9 As shown, the overlap portion 210 of the second side wall 20 does not have a reinforcing rib 2a. Figure 12 As shown, the reinforcing ribs 2a in the assembled state have a smooth transition. In particular, the reinforcing ribs (2a) are at least arranged on the two side extension rings 2 parallel to the vehicle door.
[0041] like Figure 17As shown, the first side wall 10 of the automobile sunroof reinforcing frame is provided with a relief opening 120 to match the peripheral member. In order to increase the strength, a folded edge structure 130 is arranged on both sides of the relief opening 120. In the embodiment, the folded edge structure 130 is partially upturned from the edge of the extension ring 2, and is substantially parallel to the extension direction of the frame body 1. It should be understood that the relief opening 120 on the first side wall 10 is only an example and is not limited, and it can be arranged on the second side wall 20 and / or the third side wall 30 and / or the fourth side wall 40 as needed.
[0042] The above is only a preferred embodiment of the present application, and is not intended to limit the scope of the present application. The above embodiment of the present application can also be variously changed. That is, any simple, equivalent changes and modifications made according to the content of the claims and the specification of the present application fall within the scope of the claims of the present application. The present application is not described in detail, and is conventional technical content.
