However, the materials and structures of the B / C pillar interior panels of existing vehicles are insufficient and cannot meet users' pursuit of high quality of life.

[0003] At present, the common B / C pillar interior panels of vehicles on the market are made of plastic parts covered with fabric and suede by hand, or directly low-pressure injection molded and covered with fabric and suede. However, the plastic substrate has a high density, resulting in a heavy part weight; although the hand-wrapped parts have a comfortable touch, the cost is high, and the low-pressure injection molded parts have a hard touch due to their own process, and the surface material of the coating does not contain foam.

[0004] In addition, on models with side air curtains, a metal guide bracket is often added to the air curtain because of the need for air curtain detonation. In addition to the high cost, the guide bracket is also heavy and takes up a large layout space. The B / C pillar interior panels also need screws or high-strength clips to fix the B / C pillar interior panels. If the roof is low, the B / C pillar interior panels may not have space for clips or screw installation points due to the travel of the seat belt height adjustment slide. Summary of the invention

[0025] Compared with the prior art, the present invention has obvious advantages and beneficial effects. By means of the above technical solution, the decorative plate of a vehicle pillar and the vehicle of the present invention can achieve considerable technical advancement and practicality, and has wide industrial utilization value, and has at least the following advantages:

[0026] (1) The body of the interior trim panel of the vehicle pillar of the present invention is made of a multi-layer composite material and is formed by compression molding, so that the body of the interior trim panel is lighter than that of a plastic material.

[0027] (2) The surface material is attached to the outer surface of the interior panel body through a molding process, so that a flexible layer, such as compliant foam, can be added between the surface material and the interior panel body, making the interior panel softer to the touch and enhancing the user experience.

[0028] (3) The air curtain guide bracket is made of plastic material, which is lighter than the existing metal material.

[0029] (4) A first limiting groove is formed between the seat belt slide rail bracket and the interior panel body, and the seat belt slide rail bracket is provided with a plurality of first protrusion structures. When the seat belt slide plate is installed in the first limiting groove, it only contacts the highest points of the plurality of first protrusion structures, thereby effectively reducing the friction of the seat belt slide plate in the first limiting groove and making the sliding of the seat belt slide plate smoother. In addition, during the installation of the interior panel, extrusion deformation usually occurs, resulting in tolerance, and the plurality of first protrusion structures can effectively absorb the tolerance, thereby ensuring that the seat belt slide plate can still slide smoothly after the installation of the interior panel is completed.

[0030] (5) A plurality of second protrusion structures are arranged on both sides of the seat belt slide plate. When the seat belt slide plate is installed in the first limiting slide groove, the plurality of second protrusion structures abut against the flange structure of the interior trim panel body, thereby avoiding the shaking of the seat belt slide plate and reducing the contact area between the seat belt slide plate and the flange structure, thereby ensuring the smooth sliding of the seat belt slide plate.

[0031] (6) A lower mounting structure of the interior panel is also connected to one end of the decorative panel body, and a mounting point base is provided on the lower mounting structure. A buckle is clamped on the mounting point base, and the buckle is directly clamped on the sheet metal of the column. The installation is simple and can effectively improve the assembly efficiency.

[0054] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the following is a detailed description of the interior trim panel of a vehicle pillar and the specific implementation method and effects of the vehicle proposed by the present invention in combination with the accompanying drawings and preferred embodiments.

[0055] An embodiment of the present invention provides an interior trim panel for a vehicle pillar, such as Figure 1 As shown, it includes: an interior trim panel body 1, a seat belt slide plate 2 and an air curtain guide bracket 3.

[0056] The interior trim panel body 1 is formed by molding a composite multilayer material; the safety belt slide plate 2 is slidably connected to the inner surface of the interior trim panel body 1 ; and the air curtain guide bracket 3 is connected to the first end of the interior trim panel body 1 .

[0057] Specifically, the interior trim panel body 1 of this embodiment is made of a high-density composite board of multi-layer composite materials, which is formed by a molding process and has the characteristics of small thickness and vectorization.

[0058] In a specific embodiment, the multi-layer composite material is composed of non-woven fabric, glass fiber, composite agent, PU sheet, base fabric and other multi-layer materials, each layer of material is bonded by glue, and then through a molding process, the interior trim panel body 1 is formed. Of course, the above material is only an embodiment, and other materials can also be used to form a multi-layer composite material, and the present application is not limited to this.

[0059] In one embodiment, the outer surface of the interior trim panel body 1 is coated with a surface material, and the surface material is a multi-layer composite material. For example, it is a composite material composed of fabric and non-woven fabric, or a composite material composed of suede and non-woven fabric. The surface material is attached to the outer surface of the interior trim panel body 1 by a molding process. The outer surface of the interior trim panel body 1 refers to the side facing the vehicle passenger space after the interior trim panel is installed on the pillar.

[0060] Furthermore, a flexible layer is provided on the side where the surface material is attached to the interior panel body 1, and the flexible layer is attached to the outer surface of the interior panel body 1 by a molding process, and then the surface material is attached to the outer surface of the interior panel body 1. The provision of the flexible layer can effectively increase the softness of the interior panel and improve the touch of the interior panel. Preferably, the flexible layer is a composite foam layer.

[0061] like Figure 1 As shown, the seat belt slide plate 2 is slidably connected to the inner surface of the interior panel body 1, so as to change the height of the seat belt by changing the position of the seat belt slide plate 2. The inner surface of the interior panel body 1 refers to the side facing the vehicle pillar after the interior panel is installed on the vehicle pillar.

[0062] In one embodiment, flange structures are provided on both sides of the interior trim panel body 1, and the two sides are the two sides along the length direction of the interior trim panel. The flange structures on both sides are connected to the seat belt slide rail bracket 11, and the seat belt slide rail bracket 11 has a plurality of first protrusion structures 111, and the plurality of first protrusion structures 111 are protrusion structures facing the interior trim panel body 1. There is a gap between the plurality of first protrusion structures 111 and the interior trim panel body 1 to form a first limiting slide groove (not shown in the figure). The two sides of the seat belt slide 2 are respectively accommodated in the corresponding first limiting slide grooves, thereby realizing the slidability of the seat belt slide 2. Among them, the two sides of the seat belt slide 2 refer to the two sides along the length direction of the seat belt slide 2.

[0063] In a specific embodiment, the plurality of first protruding structures 111 are arched protruding structures. Furthermore, the plurality of first protruding structures 111 on each safety belt slide rail bracket 11 are sequentially connected end to end to form a wave-shaped structure.

[0064] In this embodiment, a first limiting slot is formed by a plurality of first protruding structures 111 and the interior panel body 1. When both sides of the seat belt slide 2 are accommodated in the first limiting slot, only the highest points of the plurality of first protruding structures 111 will contact the seat belt slide 2. Thus, while limiting the seat belt slide 2, the contact area between the first limiting slot and the seat belt slide 2 is reduced, thereby reducing friction and effectively ensuring the smoothness of the sliding of the seat belt slide 2. In addition, during the installation of the interior panel, the interior panel will have a certain tolerance due to the extrusion effect, and the first protruding structure 111 adopts an arched structure design, which can absorb the tolerance through deformation, and thus after the interior panel is installed, the smoothness of the sliding of the seat belt slide 2 can still be ensured.

[0065] In one embodiment, if Figure 3 As shown, the edges on both sides of the seat belt slide plate 2, that is, the edges on both sides accommodated in the first limiting slide groove, are provided with a plurality of second protrusion structures 21. When the two sides of the seat belt slide plate 2 are accommodated in the first limiting slide groove, the plurality of second protrusion structures 21 abut against the flange structures on both sides of the interior trim body 1. Thus, the shaking of the seat belt slide plate 2 can be effectively prevented. At the same time, only the highest point of the second protrusion structure 21 contacts the flange structure, so the contact area is small, the friction force generated is small, and no excessive resistance is generated to the sliding of the seat belt slide plate 2.

[0066] In one specific embodiment, the second protruding structure 21 is an arc-shaped protruding structure.

[0067] like Figure 3 As shown, the seat belt slide plate 2 is provided with a button mounting hole (not shown in the figure), a seat belt outlet 22 and a seat belt height adjustment button 23.

[0068] Among them, the inner surface of the seat belt slide plate 2 is respectively provided with second limiting grooves 24 on both sides of the button installation hole, and the seat belt height adjustment button 23 is slidably connected to the second limiting grooves 24. A return spring 25 is connected between the seat belt slide plate 2 and the seat belt height adjustment button 23, and the seat belt height adjustment button 23 is provided with a press button 231, and the press button 231 is penetrated through the button installation hole. The back side of the seat belt height adjustment button 23 (the side facing the pillar after the interior panel is installed) is provided with an unlocking mechanism 232, and after the press button 231 is pressed, it abuts against the unlocking mechanism 232 to unlock the seat belt slide plate 2, so that it can slide to adjust the height of the seat belt. When the pressing of the press button 231 is canceled, under the action of the return spring 26, the press button 231 is reset, and the seat belt slide plate 2 is locked again.

[0069] like Figure 2 As shown, a seat belt slide plate mounting hole 12 is also provided on the interior panel body 1. When the seat belt slide plate 2 is installed on the interior panel body 1, the push button 231 and the seat belt outlet 22 are presented on the outside of the interior panel through the seat belt slide plate mounting hole 12 for user operation.

[0070] like Figure 1 As shown, an air curtain guide bracket 3 is connected to the first end of the interior panel body 1, and the air curtain guide bracket 3 can be connected to the interior panel body 1 by pasting. The first end of the interior panel body 1 is the upper end after the interior panel is installed on the vehicle pillar.

[0071] In one embodiment, an interior panel mounting structure 31 is further provided on the air curtain guide bracket 3 , and the interior panel is fixedly mounted on the vehicle pillar through the interior panel mounting structure 31 .

[0072] Specifically, the interior panel mounting structure 31 and the air curtain guide bracket 3 are integrally formed, and the material thereof is plastic, such as polyethylene, polypropylene, polyvinyl chloride, etc.

[0073] In this embodiment, the interior panel mounting structure 31 and the air curtain guide bracket 3 are integrally formed with plastic material, thereby effectively reducing the overall weight of the interior panel, and the integrally formed interior panel mounting structure 31 is directly connected to the sheet metal of the vehicle pillar, eliminating the need for independently setting up clips and saving costs.

[0074] like Figure 1As shown, the second end of the interior panel body 1 is connected to the interior panel lower mounting structure 4, and a plurality of mounting point bases 41 are also provided on the interior panel lower mounting structure 4, and a buckle 42 is clamped on the plurality of mounting point bases 41. When the interior panel is mounted on the vehicle pillar, it is clamped to the sheet metal of the vehicle pillar through the buckle 42. The second end of the interior panel body 1 is the lower end after the interior panel is mounted on the vehicle pillar.

[0075] The buckle 42 is made of plastic, which can effectively save costs while reducing the overall weight of the interior trim panel.

[0076] An embodiment of the present invention further provides a vehicle, comprising an interior trim panel of a vehicle pillar according to any of the above embodiments.

[0077] The pillar may be a B-pillar or a C-pillar of the vehicle.
