The triangular plate is an important part of the car door, mainly used to cover the triangular window or the bolts of the exterior rearview mirror, improving the overall appearance quality of the vehicle. The triangular area where the triangular plate is located is the most sensitive area for wind noise. If the upper and lower cavities of the door are connected, it will cause noise from the door cavities to be transmitted between each other and even amplified. Therefore, the cavity sealing design of the door triangular area is particularly crucial for reducing wind noise. However, existing door triangular area cavity sealing structures are complex to install. Summary of the Invention

[0020] Compared to existing technologies, the technical solution proposed in this invention provides an overall frame structure for the entire triangular plate assembly through a set plate body.

[0036] With the rapid development of the automotive industry and the increasing popularity of vehicles, people have higher and higher requirements for the perceived quality of vehicles. Against this backdrop, automotive NVH performance and energy conservation and emission reduction have gradually become the focus of the automotive industry. The door sheet metal has two large cavities: the front cavity and the rear cavity. This results in the upper and lower cavities being connected along the waterline of the door, allowing sound to be transmitted and amplified vertically. To isolate or seal these cavities, two separate seals are needed, requiring the design of two mounting brackets and two sets of molds. Furthermore, the installation process is complex and costly.

[0037] In view of this, embodiments of the present invention provide a triangular plate assembly, a car door, and a vehicle. By integrating the conformal end into the plate body, the design of mounting brackets is reduced, the assembly process of the conformal end is simplified, and when the plate body is assembled with the car door, the conformal end can be directly inserted into the cavity to achieve a seal, making the cavity sealing structure of the car door triangular area simpler and more convenient.

[0038] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0039] like Figure 1 As shown in the figure, a triangular plate assembly proposed in this embodiment of the invention includes:

[0040] Plate body 10; and

[0041] The conformal end 20 is provided at both ends of the plate body 10 along the length direction of the vehicle to seal the cavity on the door body 40. After the plate body 10 is assembled with the door, the plate body 10 abuts against the upper end of the door body 40. The conformal end 20 and the plate body 10 together form a sealing surface for sealing the door body 40.

[0042] In this embodiment, the plate body 10 provides an overall frame structure for the entire triangular plate assembly. The plate body 10 can be snapped into the door sheet metal, thus achieving a fixed connection between the triangular plate assembly and the door. To facilitate sealing the cavities on the door body 40, a conformal end 20 is provided at each end of the plate body 10. After the plate body 10 is assembled with the door, the conformal end 20 can be inserted into the corresponding cavities, thereby sealing the cavities and preventing wind noise problems when the vehicle is traveling at high speeds. Moreover, after the plate body 10 is assembled, the lower end of the plate body 10 abuts against the upper end of the door body 40, ensuring a tight contact between the plate body 10 and the door body and preventing gaps. With this configuration, the plate body 10 and the door body are in sealed contact, and the conformal end 20 seals the cavities, thus forming a continuous and complete sealing surface, improving the overall sealing effect of the vehicle. In addition, the conformal end 20 is integrated on the plate body 10, which can save the setting of mounting brackets, thereby simplifying the assembly process, reducing the complexity of sealing structure installation, and also reducing technology development and production costs.

[0043] In this embodiment, the triangular plate assembly can be installed at the door, adjacent to the door body 40, side panel, and window glass, mainly for beautifying the vehicle body. Specifically, the triangular plate assembly can include a plate body 10 and conformal end caps 20. The plate body 10 can be fixed to the door sheet metal by snap-fit, thereby fixing the plate body 10 to the door and ensuring reliable installation. To further improve the stability of the plate body 10, a support structure can be provided between the plate body 10 and the door sheet metal. The support structure can control the pressure deformation of the plate body 10 and avoid appearance quality defects caused by pressure collapse. The support structure can be a support frame, support rod, or support plate, etc., and is not limited here. Preferably, the support structures can be staggered, which can further improve the support for the plate body 10 and is beneficial to the stability of the plate body 10. The conformal end caps 20 are provided at both ends of the plate body 10. One conformal end cap 20 can be provided at each end of the plate body 10, mainly for sealing the front cavity and rear cavity of the door panel. Understandably, one conformal end 20 is used to seal the front cavity of the door panel, and the other conformal end 20 is used to seal the rear cavity of the door panel. This achieves the sealing of the cavities on the door sheet metal, preventing wind noise. Moreover, the conformal end 20 is integrated into the panel body 10. When assembling the panel body 10, the conformal end 20 can be simultaneously inserted into the cavity of the door sheet metal to achieve cavity sealing. The entire process of the conformal end 20 sealing the door cavity does not require a separate mounting bracket, reducing the number of parts used and lowering the complexity of door cavity sealing. Sealing the door cavity can be achieved simultaneously with the assembly of the panel body 10. This design avoids sound transmission and amplification within the door cavity, improving the overall vehicle's noise reduction effect. In one embodiment, the conformal end 20 is adapted to the shape of the door cavity, allowing for better contact with the inner wall of the cavity and improving the sealing effect of the conformal end 20 on the door cavity. Preferably, the conformal end 20 can be interference-fitted with the door cavity, that is, the conformal end 20 has a certain amount of interference with the door cavity, which can be 3-5 mm. This ensures that the conformal end 20 fills the entire door cavity, thereby improving the sealing effect of the conformal end 20 on the door cavity.

[0044] Furthermore, refer to Figure 2-3In one embodiment of the present invention, the triangular plate assembly further includes a sound-insulating pad 30, which is disposed on one side of the plate body 10, and the conformal end 20 is integrally formed with the sound-insulating pad 30. To further reduce wind noise and improve the quietness effect, the triangular plate assembly further includes a sound-insulating pad 30, which is disposed on one side of the plate body 10. The sound-insulating pad 30 can absorb some of the noise from the external environment, preventing external noise from entering the vehicle interior, thereby providing a quiet riding environment for the occupants. In this embodiment, the sound-insulating pad 30 can be bonded to the plate body 10, specifically using double-sided adhesive, preferably 3M double-sided adhesive. Bonding the sound-insulating pad 30 is convenient and provides a secure fixation. In one embodiment, the sound-insulating pad 30 and the conformal end 20 are integrally formed, which simplifies the manufacturing or assembly process of the triangular plate assembly and improves the sealing performance of the connection between the sound-insulating pad 30 and the conformal end 20. Understandably, the sound insulation pad 30 and the conformal end 20 are first injection molded together, and then the sound insulation pad 30 is glued to the plate body 10, thus forming the entire triangular plate assembly, which is then assembled into the car door to achieve the sealing of the door cavity by the conformal end 20. In other embodiments, markings can be set on the sound insulation pad 30 to avoid mixing the left and right sides of the sound insulation pad 30.

[0045] Furthermore, in one embodiment of the present invention, the conformal end 20 is made of foamed material, which can be made of raw materials such as plastic and rubber, with the addition of catalysts, foam stabilizers, foaming agents and other auxiliary materials. Through physical foaming or cross-linking foaming, a large number of fine foams appear in the plastic and rubber, increasing the volume and decreasing the density, making it lightweight and soft, and possessing functions such as buffering, sound absorption and sealing, which can effectively achieve the sealing of the car door cavity.

[0046] Furthermore, refer to Figure 2 , Figure 3 as well as Figure 5In one embodiment of the present invention, the plate body 10 has a front end and a rear end along the length direction of the vehicle. A conformal end 20 at the front end is a first conformal end, which includes a connecting portion 21 and an insert portion 22. One end of the connecting portion 21 is connected to the plate body 10 and extends along the length direction of the vehicle. The cavity wall has a first recess, and the end of the connecting portion 21 facing away from the plate body 10 is filled within the first recess. One end of the insert portion 22 is bent and connected to the end of the connecting portion 21 facing away from the plate body 10, and the other end extends away from the connecting portion 21. The cavity wall has a second recess 43, and the end of the insert portion 22 facing away from the plate body 10 abuts against the second recess 43 near the inner wall of the plate body 10. To further improve the sealing effect of the cavity, the first conformal end may include the insert portion 22 and the connecting portion 21. The connecting portion 21 can extend along the length direction of the cavity, increasing the contact area between the conformal end and the cavity, thereby improving the sealing effect of the cavity along its length. The embedding part 22 can extend along the width direction of the cavity, allowing it to better fit against the inner wall of the cavity, thereby improving the sealing effect of the cavity in the width direction. It is understood that the connection part 21 and the embedding part 22 effectively seal the door cavity, improving the sealing effect. In this embodiment, the connection part 21 and the embedding part 22 are integrally formed, which improves the overall strength. Furthermore, the integrally formed connection part 21 and the embedding part 22 have relatively good overall sealing performance, further enhancing the sealing effect. It is understood that a first recess is provided in the cavity wall, and the connection part 21 can fill the first recess, thereby sealing the first recess and preventing airflow, thus improving the sealing effect of the cavity. Additionally, the embedding part 22 can extend into the second recess 43, abutting against the inner wall of the second recess 43, improving the sealing effect and preventing outside air from convection with inside air through the second recess 43, reducing wind noise. Preferably, the inner wall of the second recess 43 near the plate body 10 is an arc surface, and the cross-section of the embedded part 22 is an arc shape corresponding to the arc surface. On the one hand, it can fit tightly with the interior of the second recess 43 to improve the sealing effect; on the other hand, it can also provide a certain deformation space, which makes it convenient for the conformal end 20 to be inserted into the cavity, and to fit tightly with the inner wall of the second recess 43 by the elastic force generated by the deformation, thereby improving the sealing effect of the cavity.

[0047] Furthermore, refer to Figure 2In one embodiment of the present invention, the first conformal end further includes a support portion 25. The support portion 25 is disposed on the side of the embedded portion 22 away from the plate body 10. One end of the support portion 25 is connected to the embedded portion 22, and the other end extends away from the embedded portion 22 and abuts against the inner wall of the second recessed portion 43 away from the plate body 10. In this embodiment, the support portion 25 connects the embedded portion 22 and the connecting portion 21, and abuts against the inner wall of the second recessed portion 43. On the one hand, it can provide support below the connecting portion 21, so that the first conformal end can withstand greater forces, improve the overall structural strength, and extend the service life. On the other hand, it can increase the contact area with the inner wall of the second recessed portion 43, thereby further improving the sealing effect.

[0048] Furthermore, refer to Figure 3 and Figure 4 In one embodiment of the present invention, the cavity wall is provided with a positioning protrusion 42, and the connecting part 21 and the supporting part 25 are provided with a positioning groove 26 on the side opposite to the embedded part 22. The positioning groove 26 cooperates with the positioning protrusion 42. In this embodiment, the cooperation between the positioning protrusion 42 and the positioning groove 26 can ensure that the first conformal end is installed in place, avoiding gaps between it and the inner wall of the cavity due to improper installation, thereby improving the sealing effect of the cavity.

[0049] Furthermore, refer to Figure 2 , Figure 3 as well as Figure 5In one embodiment of the present invention, the conformal end 20 located at the rear end is a second conformal end. The second conformal end includes a sealing portion 23 and an extension portion 27. One end of the sealing portion 23 is connected to the plate body 10, and the other end extends towards the bottom of the cavity. The extension portion 27 is bent and connected to the end of the sealing portion 23 away from the plate body. The cavity wall is provided with a limiting groove 44, and the end of the extension portion 27 away from the sealing portion 23 fills the limiting groove 44. In this embodiment, the sealing portion 23 is used to seal the cavity. It can be understood that the width of the sealing portion 23 is equal to or greater than the width of the cavity, so that the entire cavity can be filled in the width direction, improving the sealing effect. The extension portion 27 can be used to fill the limiting groove 44 to achieve the sealing of the limiting groove 44. It can be understood that the end of the extension portion 27 away from the sealing portion 23 is inserted into the limiting groove 44, thereby filling the limiting groove 44 and improving the sealing effect of the cavity. Furthermore, the cooperation between the extension 27 and the limiting groove 44 can improve the reliability of the second conformal end after installation in the cavity. Preferably, the thickness of the extension 27 decreases from the end near the sealing part 23 to the end away from the sealing part 23. It can be understood that the end of the extension 27 away from the sealing part 23 has the smallest thickness, which facilitates the insertion of the extension 27 into the limiting groove 44. The end of the extension 27 near the sealing part 23 has the largest thickness, which can improve the structural strength of the extension 27, prevent the extension 27 from breaking, and also increase the contact area with the limiting groove 44, further improving the sealing effect.

[0050] Furthermore, refer to Figure 3 and Figure 4 In one embodiment of the present invention, the sealing portion 23 has a protrusion 24 on the side opposite to the extension portion 27, and the cavity wall has a groove 41, with the protrusion 24 engaging with the groove 41. In this embodiment, the protrusion 24 can be used to seal the groove 41 on the cavity wall, improving the sealing effect. Moreover, the engagement of the protrusion 24 and the groove 41 can further improve the stability of the second conformal end after it is installed in the cavity.

[0051] To achieve the above objectives, refer to Figure 1 This invention provides a vehicle door, comprising a door body 40, a side panel disposed on one side of the door body, and a triangular plate assembly. The triangular plate assembly is the triangular plate assembly described above, with its main body fixedly connected to the side panel and abutting against the upper end of the door body 40. Its conformal end extends into the cavity of the door body 40 to seal the cavity. Since this vehicle door employs all the technical solutions of the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon further here.
