In the description of the present application, the meaning of "a plurality" or "several" is two or more, unless otherwise specifically defined.

[0028] Please refer to Figures 1 to 9 together, and now the door triangle plate provided by the present utility model will be described. The door triangle plate is used for being installed at the position of the door triangle window and includes a hard body 10 and a flexible edge strip 20 which are integrally injection molded. The flexible edge strip 20 is used for abutting against the decorative strip 50 on the front side of the window frame. Among them, the edge of the hard body 10 facing the decorative strip 50 has a first joint surface 101 and a second joint surface 102. The first joint surface 101 and the second joint surface 102 are arranged at an angle. The flexible edge strip 20 has a third joint surface 201 and a fourth joint surface 202. The first joint surface 101 and the third joint surface 201 are connected, and the second joint surface 102 and the fourth joint surface 202 are connected.

[0029] It should be understood that the installation method of the door triangle panel at the position of the door triangle window can be to connect it to the door sheet metal by using the installation points of the door triangle panel itself, or to connect it to the door sheet metal with the help of an intermediate connecting member such as a bracket-like member. In this embodiment, the installation points can be directly formed on the rigid body 10, or bracket-like members can be installed on the rigid body 10 by means of bonding or screwing. In addition, a decorative strip 50 is usually installed at the boundary of the vehicle window frame to cover the sheet metal boundary, thereby enhancing the appearance texture. The decorative strip 50 can specifically be a chrome-plated bright strip or a plastic dark strip with better corrosion resistance. Specifically, in this embodiment, the decorative strip 50 is buckled on the flexible edge strip 20 integrally formed on the front side edge of the rigid body 10, and the seamless tight fit between the decorative strip 50 is ensured by using the compression deformation ability of the flexible edge strip 20.

[0030] It should be noted that in this embodiment, the rigid body 10 can specifically be ASA engineering plastic, and the flexible edge strip 20 can specifically be TPV (Thermoplastic Vulcanizate) material. The rigid body 10 and the flexible edge strip 20 are integrally formed by using a two-color injection molding process (two-color injection molding refers to the molding process of injecting two different materials into the same set of molds, so that the molded part is formed by two materials. Some two materials are of different colors, and some two materials are different in hardness, which can improve the aesthetics and assembly performance of the molded part), so as to ensure the bonding force between the flexible edge strip 20 and the rigid body 10, not only avoiding the joint problem, but also reducing the risk of the flexible edge strip 20 falling off.

[0031] In this embodiment, the front side boundary of the rigid body 10 forms an L-shaped joint angle based on the first joint surface 101 and the second joint surface 102 set based on an included angle, and the flexible edge strip 20 also forms an L-shaped joint angle based on the third joint surface 201 and the fourth joint surface 202. Of course, the two L-shaped joint angles are a complementary male and female angle. Specifically, the first joint surface 101 and the second joint surface 102 form a female angle structure, and the third joint surface 201 and the fourth joint surface 202 form a male angle structure. The male angle structure is embedded in the female angle structure so that the first joint surface 101 is seamlessly connected to the third joint surface 201, and the second joint surface 102 is seamlessly connected to the fourth joint surface 202, thereby increasing the joint area between the flexible edge strip 20 and the rigid body 10, and thus improving the bonding force between the flexible edge strip 20 and the rigid body 10.

[0032] Compared with the prior art, the door triangular panel provided in this embodiment integrally forms a flexible edge strip 20 at the edge of the rigid body 10 facing the decorative strip 50. By utilizing the flexible deformation ability of the flexible edge strip 20, it can be tightly attached to the decorative strip 50 stably, thereby reducing the wind noise generated during driving due to the loose fit between the door triangular panel and the decorative strip 50, and contributing to the improvement of the vehicle NVH performance; the first joint surface 101 and the second joint surface 102 formed at an angle at the edge of the rigid body 10 can be correspondingly connected to the third joint surface 201 and the fourth joint surface 202 on the flexible edge strip 20. Thereby, the bonding area between the flexible edge strip 20 and the rigid body 10 can be increased, and the connection reliability between the flexible edge strip 20 and the rigid body 10 can be improved. This can not only prevent the flexible edge strip 20 from falling off, but also avoid the occurrence of gaps between the flexible edge strip 20 and the rigid body 10, resulting in wind noise problems, and further improve the vehicle NVH performance.

[0033] In some embodiments, referring to Figures 3 to 5 , a plurality of ribs 1011 are spaced apart along the extending direction of the flexible edge strip 20 on the first joint surface 101 and / or the second joint surface 102, and a plurality of grooves 2011 are spaced apart on the second joint surface 102 and / or the fourth joint surface 202. Each rib 1011 is respectively embedded in each groove 2011.

[0034] In the two-color injection molding process, the rigid body 10 and the flexible edge strip 20 are molded successively. Specifically, when the rigid body 10 is first molded, the ribs 1011 are formed together. Subsequently, during the molding process of the flexible edge strip 20, the TPV material wraps the ribs 1011 to form the grooves 2011, thereby forming a mating form in which the ribs 1011 and the grooves 2011 are embedded. At the same time, the surface of the rib 1011 and the groove wall of the groove 2011 can also be combined with each other, which can not only improve the bonding force between the flexible edge strip 20 and the rigid body 10, prevent the flexible edge strip 20 from falling off, but also avoid the generation of parting seams between the flexible edge strip 20 and the rigid body 10, resulting in appearance and driving wind noise problems, thereby improving the assembly aesthetics of the door triangular window and the vehicle NVH performance.

[0035] Optionally, the above-mentioned ribs 1011 can be formed on the first joint surface 101, or on the second joint surface 102, or at the intersection of the first joint surface 101 and the second joint surface 102, or ribs 1011 are formed on both the first joint surface 101 and the second joint surface 102. Considering the injection molding demolding problem, it is preferable to form the ribs 1011 on the first joint surface 101 here, and at the same time, the ribs 1011 should have a draft angle; based on the forming position of the ribs 1011, the groove 2011 can be correspondingly formed on the third joint surface 201 or the fourth joint surface 202, or at the intersection of the third joint surface 201 and the fourth joint surface 202, or grooves 2011 are correspondingly formed on both the third joint surface 201 and the fourth joint surface 202. Here, it is preferable to form the ribs 1011 on the first joint surface 101 and correspondingly form the groove 2011 on the third joint surface 201, thereby reducing the processing difficulty of the process.

[0036] In some embodiments, please refer to Figure 4 and Figure 5 As shown, a glue inlet notch 1021 is provided in the middle of the first joint surface 101 and / or the second joint surface 102, and a joint boss 2021 is formed on the third joint surface 201 and / or the fourth joint surface 202. The joint boss 2021 is embedded in the glue inlet notch 1021. When the flexible side strip 20 is formed by a two-color injection molding process, the TPV material flows into the glue inlet notch 1021 reserved on the previously formed rigid body 10 to form the joint boss 2021, and finally a structural form in which the joint boss 2021 is embedded in the glue inlet notch 1021 is formed. On the one hand, the axial position of the flexible side strip 20 on the rigid body 10 can be restricted by the engagement of the joint boss 2021 and the glue inlet notch 1021, thereby avoiding the misalignment of the flexible side strip 20 due to axial force. On the other hand, the connection reliability of the flexible side strip 20 on the rigid body 10 can be further improved by combining the surface of the joint boss 2021 and the groove wall of the glue inlet notch 1021, avoiding the problems of surface quality and wind noise caused by the flexible side strip 20 falling off and separating from the rigid body 10, thereby improving the appearance texture and the vehicle NVH performance.

[0037] It should be noted that the above-mentioned glue inlet slot 1021 can be provided on the first joint surface 101, or on the second joint surface 102, or glue inlet slots 1021 can be provided on both the first joint surface 101 and the second joint surface 102. Considering the convenience of injection molding demolding, in this embodiment, it is preferably to set the glue inlet slot 1021 on the second joint surface 102. Especially when there are ribs 1011 on the first joint surface 101, the demolding directions of the glue inlet slot 1021 and the ribs 1011 are made consistent, so as to meet the requirements of injection molding demolding. Correspondingly, the combined boss 2021 can be provided on the third joint surface 201, or on the fourth joint surface 202, or combined bosses 2021 can be provided on both the third joint surface 201 and the fourth joint surface 202. Here, corresponding to the glue inlet slot 1021 provided on the second joint surface 102, it is preferably to form a combined boss 2021 at the corresponding position on the fourth joint surface 202. On this basis, if there is a groove 2011 formed on the third joint surface 201 corresponding to the ribs 1011, the demolding directions of the combined boss 2021 and the groove 2011 should be made consistent, so as to reduce the difficulty of the two-color injection molding process.

[0038] As a specific implementation manner of the above-mentioned rigid body 10, please refer to Figure 4 、 Figure 6 and Figure 7 , an outer extension edge 11 is provided at the front edge of the rigid body 10, and the inner surface of the outer extension edge 11 forms the first joint surface 101; a rib edge 12 protruding inwards is provided on the outer extension edge 11, and the front surface of the rib edge 12 forms the second joint surface 102.

[0039] Here, the outer extension edge 11 and the rib edge 12 form an L shape, so that the first joint surface 101 and the second joint surface 102 form an internal angle structure. On the one hand, it can ensure a sufficient bonding area between the flexible edge strip 20 and the rigid body 10, thereby improving the bonding force between the flexible edge strip 20 and the rigid body 10. On the other hand, it can use the L-shaped structure to improve the structural strength of the front edge of the rigid body 10, so as to provide sufficient supporting force for the flexible edge strip 20 by the front edge of the rigid body 10, and further ensure the tightness of the abutment between the flexible edge strip 20 and the decorative strip 50, avoiding the problem of small gaps caused by the insufficient tightness between the flexible edge strip 20 and the decorative strip 50 and generating driving wind noise, and improving the vehicle NVH performance.

[0040] In some possible implementation manners, please refer to Figure 7 and Figure 9 , a first notch 111 is provided at the lower end of the outer extension edge 11, a second notch 121 is provided at the lower end of the rib edge 12, a first limiting block 2012 is provided at the lower end of the third joint surface 201, the first limiting block 2012 is fitted into the first notch 111, a second limiting block 2022 is provided at the lower end of the fourth joint surface 202, and the second limiting block 2022 is fitted into the second notch 121.

[0041] The rear bottom corner position of the rigid body 10 forms a stepped notch structure based on the first notch 111 and the second notch 121. The lower end of the flexible side strip 20 forms a stepped convex structure based on the first limiting block 2012 and the second limiting block 2022. The convex structure is embedded in the notch structure, so that the flexible side strip 20 obtains axial limit on the rigid body 10, avoiding the problem of dislocation and separation between the flexible side strip 20 and the rigid body 10 caused by friction with the flexible side strip 20 during the lifting and lowering of the vehicle door glass. At the same time, the stepped structure can increase the bonding area between the lower end of the flexible side strip 20 and the rigid body 10, thereby improving the bonding force between the lower end of the flexible side strip 20 and the rigid body 10, avoiding the problem of warping of the lower end of the flexible side strip 20 due to force, and further avoiding the problem of detachment of the flexible side strip 20, improving the connection reliability between the flexible side strip 20 and the rigid body 10.

[0042] As a further deformed structure of the above-mentioned rigid body 10, please refer to Figure 4 and Figure 6 , the rear side edge of the rigid body 10 is bent inward to form a wrapped edge 13, and the top of the wrapped edge 13 is connected to the top of the ribbed edge 12. The wrapped edge 13 formed by bending the rear side edge of the rigid body 10 can improve the structural strength of the rear side edge of the rigid body 10, and at the same time, connecting the top of the ribbed edge 12 to the top of the wrapped edge 13 can improve the overall structural strength of the rigid body 10.

[0043] Specifically, please refer to Figure 6 and Figure 8 , in this embodiment, the top of the outer extension edge 11 is bent inward to form an inner folding angle 112, and the inner folding angle 112 is connected to the wrapped edge 13; the top of the third joint surface 201 is bent inward to form an outer folding angle 2013, and the outer folding angle 2013 is embedded in the inner folding angle 112. Since the rigid body 10 needs to be adapted to the shape of the triangular window, the top of the rigid body 10 is a corner structure matching the apex angle of the triangular window. Here, the top of the outer extension edge 11 is bent to form an inner folding angle 112 to shield the inner folding angle 112 formed by bending the third joint surface 201. On the one hand, the top of the outer extension edge 11 can protect the top of the flexible side strip 20, avoiding the problem of warping of the top of the flexible side strip 20 due to external scraping, and further avoiding the problem of detachment of the flexible side strip 20. On the other hand, the bonding force between the top of the flexible side strip 20 and the rigid body 10 can be improved by the fitting of the inner folding angle 112 and the outer folding angle 2013, further reducing the risk of detachment of the flexible side strip 20.

[0044] It should be noted that in combination with Figure 2 and Figure 4, in some embodiments, the edge wrapping 13 and the rib edge 12 enclose a filling cavity 14 on the inner surface of the rigid body 10, and a filling body 30 is arranged in the filling cavity 14. Here, in order to prevent high-speed airflow from pouring into the gap between the rigid body 10 and the car door sheet metal during driving, the filling body 30 is used to block the gap, thereby further reducing wind noise and improving the vehicle NVH performance; here, the filling body 30 can specifically be foaming glue or a sponge body. Using the edge wrapping 13 and the rib edge 12 to form the filling cavity 14 can position and constrain the filling body 30, thereby preventing the filling body 30 from being displaced and falling off.

[0045] Based on the above embodiments, please refer to Figure 2 , an installation skeleton 40 is connected to the inner surface of the rigid body 10, and a plurality of car door sheet metal connection points 41 are distributed at intervals on the installation skeleton 40. Since there is a gap between the rigid body 10 and the car door sheet metal, the installation skeleton 40 can be connected to the inner surface of the rigid body 10 by means of bonding or plastic welding. The car door sheet metal is connected through the car door sheet metal connection points 41 arranged on the installation skeleton 40. The specific connection method can be screw connection, riveting or welding. Here, screw connection is preferably used to facilitate assembly and meet the requirements of disassembly and replacement.

[0046] It should be noted that since the installation skeleton 40 is connected to the inner surface of the rigid body 10, when the filling body 30 is arranged in the above-mentioned filling cavity 14, the filling body 30 covers the surface of the installation skeleton 40 and is provided with avoidance holes corresponding to the positions of the respective car door sheet metal connection points 41. This not only facilitates the connection between the installation skeleton 40 and the car door sheet metal, but also can use the filling body 30 to block the gap between the rigid body 10 and the car door sheet metal, thereby reducing driving wind noise and improving the vehicle NVH performance.

[0047] Based on the same inventive concept, in combination with Figures 1 to 9 understanding, an embodiment of the present application further provides a vehicle, including the above-mentioned car door triangle plate.

[0048] Compared with the prior art, the vehicle provided in this embodiment adopts the above-mentioned car door triangle plate. Using the flexible edge strip 20 to closely adhere to the decorative strip 50 can reduce the wind noise generated during driving due to the loose fit between the car door triangle plate and the decorative strip 50, which helps to improve the vehicle NVH performance; the first joint surface 101 and the second joint surface 102 formed at an angle at the edge of the rigid body 10 can be correspondingly connected to the third joint surface 201 and the fourth joint surface 202 on the flexible edge strip 20. Thereby, the joint area between the flexible edge strip 20 and the rigid body 10 can be increased, thereby improving the connection reliability between the flexible edge strip 20 and the rigid body 10. This can not only prevent the flexible edge strip 20 from falling off, but also avoid the occurrence of gaps between the flexible edge strip 20 and the rigid body 10, resulting in wind noise problems, and further improve the vehicle NVH performance.

[0049] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
