[0040] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0041] The present embodiment relates to a roof interior panel mounting structure, which is used to mount a roof interior panel 2 on a roof sheet metal 1. The mounting structure in the prior art is specifically a plurality of clips, which are manually used to clip the roof interior panel 2 onto the roof sheet metal 1, thereby achieving the installation of the roof interior panel mounting structure. This installation method using multiple clips has the problems of low installation efficiency, high installation labor cost and high component cost. The roof interior panel mounting structure of the present embodiment aims to optimize its own structure and improve the installation efficiency of the roof interior panel 2 on the roof sheet metal 1.

[0042] In terms of overall composition, Figure 1 and Figure 2 As shown in , the roof interior panel installation structure in this embodiment includes a clamping structure and a supporting structure provided on the roof interior panel 2, and the clamping structure and the supporting structure are arranged in a staggered manner in the vertical direction of the vehicle, and a clamping space is formed between the two. Among them, the roof interior panel 2 can be clamped on the roof sheet metal 1 from bottom to top along the vehicle through the clamping space, and the clamping structure is clamped on the top of the roof sheet metal 1, and the supporting structure is supported on the bottom of the roof sheet metal 1.

[0043] The roof interior panel installation structure described in this embodiment is that the clamping structure and the support structure on the roof interior panel 2 are arranged in a staggered manner in the vertical direction of the vehicle, and a clamping space is formed between the two, so that the roof interior panel 2 is clamped on the roof sheet metal 1 from bottom to top along the vehicle through the clamping space, and the clamping structure is clamped on the top of the roof sheet metal 1, and the support structure is supported on the bottom of the roof sheet metal 1. In other words, when installing, the roof interior panel 2 only needs to be moved along the vertical direction of the vehicle to be clamped and connected with the roof sheet metal 1, thereby realizing the installation of the roof interior panel 2 on the roof sheet metal 1, which has the advantages of simple operation and easy implementation.

[0044] Compared with the prior art solution of installing the top cover interior panel 2 with multiple clips, it not only saves the cost of clip parts and the cost of manual assembly time, but also helps to improve assembly efficiency. In addition, the top cover interior panel 2 in the clipped state is subjected to more uniform force and has better installation stability.

[0045] The specific structure is Figure 3 and Figure 4 As shown in the figure, the top cover sheet metal 1 is used as the installation carrier of the top cover interior panel 2, and its four sides are installed on the top of the vehicle body. The specific installation structure can refer to the prior art. A skylight window 100 is provided on the top cover sheet metal 1. The skylight glass 3 is installed at the skylight window 100. The specific installation method can refer to the prior art. The interior panel body 201 has a through hole 200 arranged corresponding to the skylight window 100. Among them, the edges of the skylight window 100 are respectively inserted into the clamping space, and the clamping structure is located at the top of the edge of the skylight window 100, and the supporting structure is located at the bottom of the edge of the skylight window 100.

[0046] As a preferred embodiment, Figure 4 As shown in , the top cover interior panel 2 in this embodiment includes an interior panel body 201 and a mounting frame 202 provided on the side of the interior panel body 201 facing away from the cab, wherein the clamping structure and the supporting structure are integrally formed on the mounting frame 202. Here, by integrally forming the clamping structure and the supporting structure on the mounting frame 202, it is easy to process and shape, and the assembly efficiency can be improved.

[0047] In terms of specific structure, the interior trim panel body 201 is plate-shaped and has the through hole 200 mentioned above, and an upper flange 203 extending upwardly corresponding to the edge of the through hole 200 is provided. The mounting frame 202 is annular and provided along the edge of the through hole 200, that is, annular and provided along the upper flange 203, and the mounting frame 202 is located outside the upper flange 203. As the upper flange 203 and the mounting frame 202 move from bottom to top through the skylight 100, the inner edge of the top cover sheet metal 1 is clamped in the clamping space, and cannot be displaced in the up and down direction of the whole vehicle, and has good mounting firmness.

[0048] As a preferred embodiment, Figure 2 and Figure 4 As shown, the clamping structure in this embodiment includes a plurality of clamping protrusions 2021 arranged at intervals along the circumference of the mounting frame 202, and the supporting structure includes a plurality of supporting protrusions 2022 arranged at intervals along the circumference of the mounting frame 202. The clamping protrusions 2021 and the supporting protrusions 2022 have simple structures and are easy to arrange and implement, which is not only conducive to forming the above-mentioned clamping space, but also the clamping protrusions 2021 have a good clamping effect, and the supporting protrusions 2022 have a good supporting effect.

[0049] As a preferred arrangement, Figure 2 and Figure 4 As shown in , the clamping protrusion 2021 and the supporting protrusion 2022 are alternately arranged along the circumference of the mounting frame 202. That is, the supporting protrusion 2022 is located between two adjacent clamping protrusions 2021, and the clamping protrusion 2021 is located between two adjacent supporting protrusions 2022. Such an arrangement is conducive to further improving the force uniformity and use stability of the top cover interior panel 2 in the clamping state. In particular, in this embodiment, the clamping protrusions 2021 and the supporting protrusions 2022 located on the left and right sides of the mounting frame 202 are symmetrically arranged, and the clamping protrusions 2021 and the supporting protrusions 2022 are alternately arranged along the length direction of the mounting frame 202. This is conducive to further improving the force uniformity of the top cover interior panel 2 in the clamping state. As for the clamping protrusions 2021 and the supporting protrusions 2022 at the front and rear ends of the mounting frame 202, it is not necessary to completely meet the adjustment of the alternating arrangement. If the arrangement space does not allow, a non-alternating arrangement method can also be adopted.

[0050] like Figure 4 As shown in , the projections of the clamping protrusion 2021 and the supporting protrusion 2022 in the height direction of the whole vehicle in this embodiment may not overlap each other. Of course, the projections of the clamping protrusion 2021 and the supporting protrusion 2022 in the height direction of the whole vehicle may also overlap partially. It should be noted that in order to enhance the supporting effect of the supporting protrusion 2022, in this embodiment, the area of ​​the supporting surface on the supporting protrusion 2022 is greater than the area of ​​the clamping surface on the clamping protrusion 2021. Of course, during specific implementation, the area size of the supporting surface and the clamping surface can also be adjusted according to the use requirements.

[0051] In order to further improve the installation efficiency of the top cover interior panel 2, in this embodiment, Figure 5 and Figure 7 As shown in , a guiding slope 2023 is provided at the top of the clamping protrusion 2021, and the guiding slope 2023 is used to guide the clamping protrusion 2021 to clamp on the top of the top cover sheet metal 1. The guiding slope 2023 has a smooth transition as a whole to further ensure the guiding effect and help avoid damaging the top cover sheet metal 1, thereby helping to improve the installation efficiency of the top cover interior panel 2 on the top cover sheet metal 1.

[0052] In addition, if Figure 3 and Figure 5 As shown in , a guide piece 102 corresponding to a plurality of snap-in protrusions 2021 is provided on the top cover sheet metal 1. Each guide piece 102 extends downward and is used to guide the snap-in protrusion 2021 to snap on the top of the top cover sheet metal 1. Here, the guide piece 102 is tilted, and its structure is simple and easy to arrange and implement. In the process of the top cover interior panel 2 moving from bottom to top, the upper flange 203 and the mounting frame 202 can be installed into the through hole 200 under the guidance of the guide piece 102 through the contact between the guide slope 2023 and the guide piece 102, so that the inner edge of the top cover sheet metal 1 is snapped in the snap-in space, which is conducive to further improving the snap-in efficiency of the top cover interior panel 2 and the top cover sheet metal 1.

[0053] Further, such as Figure 3 As shown in , the top cover sheet metal 1 is provided with a flange arranged along the edge of the skylight 100, and the flange is folded downward along the vertical direction of the whole vehicle. In order to distinguish it from the upper flange 203 mentioned above, the flange on the top cover sheet metal 1 is called the lower flange 101, and the guide piece 102 is arranged on the lower flange 101. The arrangement of the lower flange 101 here is conducive to improving the structural strength of the top cover sheet metal 1, and the arrangement of the guide piece 102 on the lower flange 101 is conducive to ensuring the guiding effect of the guide piece 102.

[0054] As a feasible implementation method, Figure 4 As shown in , the clamping protrusion 2021 and the supporting protrusion 2022 are formed by protruding from one side to the other side in the thickness direction of the mounting frame 202. Specifically, the mounting frame 202 is arranged in accordance with the upper flange 203 on the interior trim body 201, which is conducive to increasing the contact area between the two, and further to improving the installation firmness of the mounting frame 202. In addition, the clamping protrusion 2021 is formed by protruding from the inner side to the outer side in the thickness direction of the mounting frame 202, and the supporting protrusion 2022 is formed by protruding from the bottom side to the top side in the thickness direction of the mounting frame 202, which is conducive to the processing and forming of the clamping protrusion 2021 and the supporting protrusion 2022, and is conducive to reducing the weight of the mounting frame 202, and further conducive to the lightweighting of the vehicle.

[0055] The mounting frame 202 in this embodiment is made of plastic and bonded to the interior panel body 201. This arrangement can not only greatly reduce material costs and processing costs compared to traditional metal frames, but also facilitates installation on the interior panel body 201.

[0056] As a preferred embodiment, the top cover interior panel 2 also includes a fabric layer 204 provided on the side of the interior panel body 201 facing the cab, and the fabric layer 204 has a edging 2043 wrapped around the edge of the mounting frame 202. The edging 2043 has a first abutting portion 2041 provided on the clamping structure, and a second abutting portion 2042 provided on the supporting structure, and the clamping structure abuts against the top cover sheet metal 1 through the first abutting portion 2041, and the supporting structure abuts against the top cover sheet metal 1 through the second abutting portion 2042. The arrangement of the first abutting portion 2041 and the second abutting portion 2042 on the edging 2043 is conducive to avoiding direct contact between the top cover interior panel 2 and the top cover sheet metal 1, which can effectively prevent the parts from rubbing against each other during the driving of the vehicle, and solve the problem of abnormal noise between the top cover interior panel 2 and the top cover sheet metal 1 when the vehicle is driving on a bumpy road section. In addition, the composition of the fabric layer 204 in this embodiment can refer to the prior art, and will not be repeated here.

[0057] When implementing it, Fig. 9 As shown in the figure, the hemming 2043 is coated on the edge of the mounting frame 202 and the upper flange 203, and is used to form the first abutting portion 2041 and the second abutting portion 2042, specifically the waste material of the hemming 2043. If the first abutting portion 2041 and the second abutting portion 2042 are not formed, the excess part of the outer edge of the hemming 2043 needs to be cut to form waste material. Therefore, the provision of the first abutting portion 2041 and the second abutting portion 2042 can improve the utilization rate of the waste material of the fabric layer 204.

[0058] As a feasible implementation method, Fig. 9 As shown in the figure, each second abutting portion 2042 is in a strip shape, extending downward from the outer edge of the edge 2043 to the top surface (supporting surface) and the outer side surface of the supporting protrusion 2022. The first abutting portion 2041 is wrapped around the root edge of each clamping protrusion 2021, and extends from the upper surface of the clamping protrusion 2021 to the lower surface (clamping surface). Such a configuration is conducive to ensuring that the first abutting portion 2041 is located between the top cover sheet metal 1 and the clamping protrusion 2021, and the second abutting portion 2042 is located between the supporting protrusion 2022 and the top cover sheet metal 1.

[0059] In addition, in order to further improve the clamping efficiency of the top cover interior panel 2, a positioning part can be provided between the front and rear ends of the top cover interior panel 2 and the top cover sheet metal 1 to facilitate the positioning of the interior panel on the top cover sheet metal 1. In specific implementation, the positioning part can include a positioning column provided on one of the top cover interior panel 2 and the top cover sheet metal 1, and a positioning hole provided on the other of the two. Here, the positioning column and the positioning hole have a simple structure, are easy to arrange and implement, and have a good positioning effect.

[0060] The top cover interior panel installation structure in the present embodiment, through the cooperation of the clamping structure and the supporting structure, can directly clamp the top cover interior panel 2 onto the top cover sheet metal 1 during the whole vehicle installation process, and has the advantages of quick and convenient operation and high installation stability. The clamping structure and the supporting structure cooperate to generate bending stress on the top cover sheet metal. Specifically, under the action of external force, bending normal stress and bending shear stress will be generated on the cross section of the top cover interior panel 2, and the two are collectively referred to as bending stress. Bending stress is beneficial to ensuring the structural performance of the top cover sheet metal.

[0061] In addition, the present embodiment also relates to a vehicle, on which the roof interior panel mounting structure as described above is provided.

[0062] The vehicle described in this embodiment is convenient for installing the roof interior panel 2 on the roof sheet metal 1 by providing the above roof interior panel installation structure, and is convenient for improving the installation efficiency and installation effect.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
