[0043] In order to strengthen and support the side interior trim panel 901 and the rear sill interior trim panel 902, and improve the overall installation strength and integrity of the interior decoration structure of the vehicle, the present application provides an automotive interior trim panel support structure.

[0044] Referring to Figures 1 to 4 the embodiment shown, the automotive interior trim panel support structure includes:

[0045] A bracket 100, the bracket 100 is generally a shell-like structure with an open bottom, and the top surface of the shell-like structure has a recess 200 and two protruding support portions;

[0046] A floor 900, the recess 200 of the bracket 100 is fixed to the floor 900;

[0047] A side interior trim panel 901, which is placed and fixed on one of the two support portions;

[0048] A rear sill interior trim panel 902, which is placed and fixed on the other of the two support portions and is joined with the side interior trim panel 901.

[0049] The technical solution provided by the present application can effectively fill the height difference between the side interior trim panel 901 and the floor 900 by optimizing the automotive interior trim panel support structure, realizing the stable installation of the side interior trim panel 901; on this basis, the strengthening and supporting effects on the rear sill interior trim panel 902 are realized, and finally the overall installation strength and integrity of the interior decoration structure of the vehicle are improved.

[0050] Figure 1 In, the bracket 100 is an integral structure as a whole, and each recess 200 and support portion are formed by the morphological change of the shell-like structure. This structure is beneficial to production and manufacturing and subsequent assembly. Further, referring to Figure 2 , there are two recesses 200, each recess 200 abuts against the floor 900, and a first connection hole 201 for cooperating with the floor 900 is provided at the bottom of each recess 200. The first connection hole 201 is used to cooperate with the first connecting member 2011 to realize the connection between the recess 200 and the floor 900. The first connecting member 2011 can be common connecting members in the automotive field such as bolts, rivets, and buckles, and the same applies hereinafter. Referring to Figure 2 、 Figure 4, near the first connection hole 201, a first positioning pin 202 is further provided. The first positioning pin 202 extends from the joint surface between the recessed portion 200 and the floor 900 towards the floor 900. Correspondingly, an adaptation structure, such as a positioning hole, is provided on the floor 900 and is adapted to the first positioning pin 202. When the bracket 100 and the floor 900 cooperate with each other, the cooperation between the first positioning pin 202 and the corresponding adaptation structure can achieve pre-positioning of the bracket 100 and the floor 900 before fastening, improve the installation efficiency and accuracy, and enhance the bonding strength between the two after fastening assembly to maintain stability. A buffer gasket 203 is also sleeved on the first positioning pin 202. The buffer gasket 203 abuts between the bracket 100 and the floor 900, eliminating the gap and avoiding abnormal noise.

[0051] In terms of the specific setting of the supporting part, the two supporting parts include:

[0052] The first supporting part 301, which has an inclined first step part 302, and the side wall interior trim panel 901 is placed and fixed on the first step part 302;

[0053] The second supporting part 303, which includes a cross arm 306. The floor 900 includes an edge part 903 and a raised part 904 that protrudes relative to the edge part 903. The recessed portion 200 of the bracket 100 is fixed to the edge part 903, and the cross arm 306 is placed and fixed on the raised part 904.

[0054] In terms of the setting details of the first supporting part 301, there are two first supporting parts 301. The first step parts 302 are provided on both of the two first supporting parts 301, and the two first step parts 302 respectively correspond to the edges on both sides of the end of the side wall interior trim panel 901 to improve the positioning effect. The two first step parts 302 and the side wall interior trim panel 901 are fixed to each other through a second connecting member 3051. Similarly, the second connecting member 3051 can be a connecting member commonly used in the automotive field, such as a bolt, a rivet, or a buckle. For the convenience of assembly, the first step part 302 is provided with a second connection hole 305 for installing the second connecting member. The second connection hole 305 can directly cooperate with the second connecting member or provide an installation position for the component that cooperates with the second connecting member. For example, the second connection hole 305 is used to install a snap nut and provide a screw connection point for the second connecting member. The cooperation between the second connection hole 305 and the second connecting member realizes the connection between the first supporting part 301 and the side wall interior trim panel 901. See Figure 1, a second positioning pin 3021 is further provided at the edge of the second connection hole 305. The second positioning pin 3021 extends from the first step portion 302 toward the side wall interior trim panel 901. Correspondingly, an adaptation structure, such as a positioning hole, which cooperates with the second positioning pin 3021, is provided on the side wall interior trim panel 901. When the bracket 100 and the side wall interior trim panel 901 cooperate with each other, the cooperation between the second positioning pin 3021 and the corresponding adaptation structure can achieve pre-positioning of the bracket 100 and the side wall interior trim panel 901 before fastening, improve the installation efficiency and installation accuracy, and improve the bonding strength between the two after fastening assembly to maintain stability. Figure 1 In the second positioning pin 3021 is only provided on one of the first support portions 301 to avoid over-positioning between the bracket 100 and the side wall interior trim panel 901 caused by multiple second positioning pins 3021 and the assembly difficulty caused by over-positioning.

[0055] In one embodiment, among the two recessed portions 200, one recessed portion 200 is provided on the second step portion 304, and the other recessed portion 200 is provided between the two first support portions 301. The two first support portions 301 are arranged in a staggered manner to adapt to the spatial position of the side wall interior trim panel 901. Similarly, the two first step portions 302 are arranged in a staggered manner.

[0056] In terms of the setting details of the second support portion 303, in one embodiment, the second support portion 303 further includes an inclined second step portion 304, and the second step portion 304 is connected to the cross arm 306. One part of the rear sill interior trim panel 902 is placed on the second step portion 304, and the other part is placed and fixed on the cross arm 306. The second step portion 304 can provide support for the rear sill interior trim panel 902 in the height direction while cooperating with the extension trend of the rear sill interior trim panel 902, and fill the height difference between the rear sill interior trim panel 902 and the edge portion 903 of the floor 900.

[0057] The rear sill interior trim panel 902, the cross arm 306, and the elevated portion 904 are stacked in sequence from top to bottom, and third connection holes 307 corresponding in position are provided among the three, and they are fixed to each other by a third connecting member (not shown in the figure) passing through the third connection holes 307. Through the mutual cooperation of the third connecting member and the self-forms of the rear sill interior trim panel 902 and the bracket 100, the rear sill interior trim panel 902 and the bracket 100 achieve mutual positioning in spatial position. In an actual product, a carpet (not shown in the figure) is laid on the floor 900. The rear sill interior trim panel 902, the cross arm 306, the carpet, and the elevated portion 904 are stacked in sequence from top to bottom, and third connection holes 307 corresponding in position are provided among the four, and they are fixed to each other by a third connecting member (not shown in the figure) passing through the third connection holes 307.

[0058] In terms of the overall configuration of the bracket 100, the outer surface of the shell-like structure of the bracket 100 is smoothly arranged, and a plurality of reinforcing ribs 101 are provided on the inner surface of the shell-like structure. The reinforcing ribs 101 are at least connected to each recessed portion 200 and the support portion to improve the structural strength. The bracket 100 is integrally obtained by an injection molding or blow molding process, and the specific material can be a polymer material, such as PP-TD20.

[0059] Reference Figures 5 to 7 As shown, each component is assembled as described in the following process:

[0060] Before installing the side interior trim panel 901 and the rear sill interior trim panel 902, the bracket 100 is first installed on the floor 900 of the vehicle frame. Among them, a part of the cross arm 306 of the bracket 100 is placed on the raised portion 904, and the recessed portion 200 of the bracket 100 abuts against the edge portion 903. During this process, the first positioning pin 202 and the edge portion 903 of the floor 900 cooperate with each other to achieve pre-positioning;

[0061] Through two first connecting members 2011 (such as screws) respectively passing through the first connection holes 201 in the two recessed portions 200, each first connecting member 2011 is respectively matched with the pre-assembled threaded members on the floor 900 to realize the connection between the bracket 100 and the floor 900. During this process, the positioning teeth 102 on the side edge of the bracket 100 further cooperate with the floor 900. For example, the positioning teeth 102 are fitted into the corresponding positioning structure of the floor 900, or the positioning teeth 102 are embedded in the carpet that cooperates with the floor 900;

[0062] When installing the side interior trim panel 901, first align the first support portion 301 and the front edge of the side interior trim panel 901, and achieve pre-positioning of the two through the second positioning pin 3021; the second connecting member 3051 is directly matched with the second connection hole 305, or the second connecting member 3051 is matched with the snap nut arranged in the second connection hole 305; the second connecting member 3051 and the second connection hole 305 cooperate with each other to realize the connection and fastening between the side interior trim panel 901 and the first support portion 301;

[0063] When installing the rear sill interior trim panel 902, stack the rear sill interior trim panel 902 on the front edges of the bracket 100 and the side interior trim panel 901; finely adjust the spatial positions of the rear sill interior trim panel 902 and the cross arm 306 relative to the raised portion 904 to achieve the alignment of each third connection hole 307. The third connecting member passes through each third connection hole, and the third connection hole on the raised portion 904 is screwed and matched with the third connecting member; the cooperation between the third connecting member and the third connection hole realizes the connection and fastening of the rear sill interior trim panel 902, the cross arm 306 of the bracket 100 and the floor 900.

[0064] During the above assembly process, the connection part between the bracket 100 and the floor 900 is shielded by the side inner trim panel 901 and the rear sill inner trim panel 902. The connection part between the bracket 100 and the leading edge of the side inner trim panel 901 is shielded by the rear sill inner trim panel 902. The connection part between the rear sill inner trim panel 902, the cross arm 306 and the floor 900 can be shielded separately by a separate decorative cover (not shown in the figure). The above assembly process finally obtains an automotive interior panel support structure without exposed connection structures, with good integrity and stability.

[0065] Based on the above, it is not difficult to understand that the present application also provides an automobile having the automotive interior panel support structure in the above technical solution. Other structures of the automobile can be implemented in combination with the prior art.

[0066] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered that the scope described in this specification is covered. When the technical features in different embodiments are shown in the same drawing, the drawing can be regarded as also disclosing the combination examples of the various embodiments involved.

[0067] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
