[0031] This invention proposes a vehicle.

[0032] In one embodiment of the present invention, such as Figures 2 to 5 As shown, the vehicle includes a door and an exterior panel 100 assembly. The door window frame is provided with a glass guide rail 500, and a glass groove 300 is provided within the glass guide rail 500. A window glass 400 is installed within the glass groove 300. The exterior panel 100 assembly includes an exterior panel 100 and a seal 200. The exterior panel 100 is connected to the glass guide rail 500 on the outside of the door, and the side of the exterior panel 100 is suspended on the outside of the window glass 400. The seal 200 includes a base 210 and a first lip 220 connected together. The side of the base 210 away from the first lip 220 is connected to the exterior panel 100, and the side of the first lip 220 away from the base 210 is used to abut against the window glass 400 to seal the gap between the exterior panel 100 and the window glass 400.

[0033] In this embodiment, the exterior trim panel 100 and the glass guide rail 500 are not designed to conform to each other, causing the side of the exterior trim panel 100 to hang outside the window glass 400, resulting in a gap between the exterior trim panel 100 and the window glass 400. When the vehicle is in motion, if airflow enters the gap between the exterior trim panel 100 and the window glass 400, it will cause vibration of the exterior trim panel 100 and the window glass 400, resulting in excessive wind noise. In the exterior trim panel 100 assembly of the present invention, the sealing member 200 is connected to the exterior trim panel 100 through the base 210 and abuts against the window glass 400 through the first lip 220, thereby sealing the gap between the exterior trim panel 100 and the window glass 400. When the vehicle is in motion, the airflow is blocked by the sealing member 200 and cannot enter the exterior trim panel 100 and the window glass 400, so the exterior trim panel 100 and the window glass 400 will not be vibrated, greatly reducing wind noise in this area, thereby improving the NVH level of the vehicle.

[0034] As Figure 1 shown in the prior art, some vehicles have an outer trim panel 100 and a glass guide rail 500 that are shaped together, and the gap between the outer trim panel 100 and the glass guide rail 500 and the gap between the outer trim panel 100 and the vehicle window glass 400 are sealed by setting a corresponding lip structure on the glass channel 300, which results in a complex structure of the glass channel 300 and an increase in processing difficulty. In the invention, when the outer trim panel 100 and the glass guide rail 500 are shaped together, the outer trim panel 100 assembly can also seal the gap between the outer trim panel 100 and the vehicle window glass 400 through the sealing member 200. The sealing member 200 has a simple structure and low processing difficulty, and can simplify the structure of the glass channel 300, which is beneficial to reducing the processing difficulty of the glass channel 300.

[0035] It should be noted that the description of the cooperation relationship or relative position relationship between the outer trim panel 100 assembly and the vehicle window glass 400 in the invention is based on the state that the outer trim panel 100 assembly is installed on the vehicle door, which will not be described in detail hereinafter.

[0036] Further, in the embodiment, as Figures 3 to 5 shown, the base body 210 has opposite first and second sides 211 and 212, the outer trim panel 100 assembly is installed on the vehicle door, the first side 211 is the windward side, and the distribution directions of the first and second sides 211 and 212 are parallel to the extension direction of the vehicle window glass 400; the first lip 220 is connected to the first side 211 and has a portion extending away from the outer trim panel 100. It can be understood that "parallel" means parallel or approximately parallel, and the windward side means the side closer to the wind direction. With reference to the traveling direction of the vehicle, when the outer trim panel 100 assembly is installed on the vehicle door, the first side 211 is located in front of the second side 212, that is, the base body 210 of the sealing member 200 will be parallel to the vehicle window glass 400, and the portion of the first lip 220 extending away from the outer trim panel 100 can block the gap between the outer trim panel 100 and the vehicle window glass 400, so that the side of the first lip 220 away from the base body 210 can abut against the vehicle window glass 400, thereby effectively sealing the gap between the outer trim panel 100 and the vehicle window glass 400 and reducing the wind noise at this position, thereby improving the NVH performance of the vehicle. Of course, in other embodiments, the base body 210 can be installed on the outer trim panel 100 in other directions, and the extension direction of the first lip 220 relative to the base body 210 can be adjusted so that the side of the first lip 220 away from the base body 210 can abut against the vehicle window glass 400.

[0037] In an embodiment, as Figure 3 and Figure 4As shown in the distribution direction of the first side 211 and the second side 212, the first lip 220 extends in a direction away from the second side 212. In this way, the first lip 220 is connected to the first side 211 of the base body 210 at an obtuse angle, and since the first side 211 is the windward side, the flow direction of the air flow will be arranged at an acute angle with the first lip 220, and the first lip 220 can better resist the air flow. During the driving of the automobile, the air flow acting on the first lip 220 can make the first lip 220 more closely adhere to the window glass 400, which is beneficial to improve the sealing effect of the sealing element 200.

[0038] Optionally, in the embodiment, as shown in Figure 2 and Figure 3 , the first lip 220 is in an arc structure protruding towards the second side 212. In this way, the deformation amount of the first lip 220 towards the second side 212 can be larger, that is, the first lip 220 can resist stronger air flow, so that the first lip 220 can reliably abut against the window glass 400, ensuring that the sealing element 200 can reliably seal the gap between the exterior trim panel 100 and the window glass 400. Optionally, in the embodiment, as shown in Figure 4 , the first lip 220 is in an arc structure protruding away from the second side 212. In this way, the first lip 220 can abut against the window glass 400 with a larger area, and can reliably abut against the window glass 400, ensuring that the sealing element 200 can reliably seal the gap between the exterior trim panel 100 and the window glass 400. Of course, in other embodiments, the first lip 220 can also extend at a fixed included angle with the base body 210.

[0039] In an embodiment, as shown in Figure 5 , in the distribution direction of the first side 211 and the second side 212, the first lip 220 extends in a direction close to the second side 212. In this way, the first lip 220 is connected to the first side 211 of the base body 210 at an acute angle, so that the first lip 220 can abut against the window glass 400 at a relatively inner position of the exterior trim panel 100 and is not easily damaged by human, so that the sealing element 200 can reliably seal the gap between the exterior trim panel 100 and the window glass 400. Of course, in other embodiments, the first lip 220 can be perpendicular or substantially perpendicular to the base body 210.

[0040] Further, in the embodiment, as shown in Figure 5As shown, the first lip 220 has an arc-shaped structure protruding away from the second side 212. In this way, the first lip 220 can abut against the window glass 400 with a larger area, reliably abutting against the window glass 400, preventing the first lip 220 from being blown away from the window glass 400, and ensuring that the sealant 200 can reliably seal the gap between the exterior trim panel 100 and the window glass 400. Of course, in other embodiments, the first lip 220 can also extend at a fixed angle to the base 210. In this case, a connecting structure connected to the second side 212 of the base 210 can be provided on the side of the first lip 220 away from the base 210 to support the first lip 220, thus ensuring that the first lip 220 can reliably abut against the window glass 400.

[0041] like Figures 2 to 5 As shown, in one embodiment, the exterior trim panel 100 includes a first trim panel body 110 and a second trim panel body 120 stacked together. When the exterior trim panel 100 assembly is installed on the vehicle door, the first trim panel body 110 is located outside the second trim panel body 120. By changing the mating structure of the first trim panel body 110 and the second trim panel body 120, the exterior trim panel 100 can have various different shapes. For example, the first trim panel body 110 and the second trim panel body 120 can be different colors or different materials. By setting different shaped slot structures on the first trim panel body 110, the second trim panel body 120 is exposed to the outside through the slot structures, or the second trim panel body 120 is provided with protrusions that pass through the slot structures. In this way, the shape of the exterior trim panel 100 can be more diversified to meet the user's pursuit of individuality.

[0042] Furthermore, the first trim panel 110 has a first flange 111 folded towards the second trim panel 120 on its side, and the second trim panel 120 has a corresponding second flange 121 on its side. The first flange 111 is located on the side of the second flange 121 away from the second side 212. That is, the side of the outer trim panel 100 has a flange structure facing the window glass 400, which helps to guide the airflow passing through the window glass 400 along the outer surface of the outer trim panel 100, thereby reducing wind resistance.

[0043] Further, the second trim body 120 has a connecting protrusion 122 protruding away from the first trim body 110, the connecting protrusion 122 is adjacent to the second flange 121, and the base 210 is connected to at least the connecting protrusion 122. It can be understood that the connecting protrusion 122 has a connecting surface parallel to the vehicle window glass 400, and the base 210 is connected to at least the connecting surface, and the direction from the first side 211 to the second side 212 of the base 210 is the same as the direction from the second flange 121 of the second trim body 120 to the connecting protrusion 122. In this way, the connecting protrusion 122 can stably connect the base 210, and the first lip 220 can seal the gap between the front side of the outer trim 100 and the vehicle window glass 400.

[0044] In an embodiment, as shown in Figure 4 and Figure 5 , the seal 200 further includes a second lip 230 connected to the first side 211. Optionally, the base 210 is connected to at least one side of the connecting protrusion 122 and the second flange 121 away from the first flange 111, and the second lip 230 covers the end surface of the second flange 121. Alternatively, as shown in Figure 2 and Figure 3 , the base 210 extends from the connecting protrusion 122 to the end surface of the first flange 111 through the second flange 121, and the second lip 230 covers the side of the first flange 111 away from the second flange 121. In the above two connection modes, the second lip 230 can enhance the connection stability of the base 210 and the outer trim 100, so that the seal 200 can stably seal the gap between the outer trim 100 and the vehicle window glass 400. Among them, the second flange 121 can be protruding towards the vehicle window glass 400 compared to the first flange 111. When the base 210 is connected to at least one side of the connecting protrusion 122 and the second flange 121 away from the first flange 111, the second lip 230 can cover the side of the second flange 121 close to the first flange 111 through the end surface of the second flange 121. In this way, the connection stability of the seal 200 and the outer trim 100 can be further improved.

[0045] In an embodiment, the base 210 is fixedly connected to the outer trim 100 by adhesion. The base 210 can be bonded to the outer trim 100 by double-sided tape or adhesive, so that the base 210 is stably connected to the outer trim 100, and the seal 200 can stably seal the gap between the vehicle window glass 400 and the outer trim 100. Of course, in other embodiments, the base 210 can be connected to the outer trim 100 by clamping, or the seal 200 and the outer trim 100 can be integrally formed by insert molding.

[0046] In an embodiment, the material of the sealing member 200 is EPDM (Ethylene Propylene Diene Monomer) or TPU (Thermoplastic Polyurethane Elastomer). TPU has excellent high tension, high pulling force, toughness and aging resistance, and also has high waterproof and moisture permeability, windproof, coldproof, antibacterial, mildewproof, warm-keeping and many other excellent properties. EPDM has the ability of oxidation resistance, ozone resistance and corrosion resistance. The sealing member 200 produced by using these two materials can stably and reliably play a sealing role between the outer trim panel 100 and the vehicle window glass 400. Of course, in other embodiments, the material of the sealing member 200 can also be nitrile rubber or silicone rubber.

[0047] The above description is only optional embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, which is made under the inventive concept of the present application, using the content of the present application specification and drawings, is included in the patent protection scope of the present application.
