[0030] Among them, the first interior decoration part 10 is formed with a first mounting hole 11, the second interior decoration part 20 and the first interior decoration part 10 are stacked, the second interior decoration part 20 is formed with a first mounting portion 21 protruding toward the first interior decoration part 10, the shape and size of the first mounting hole 11 can be adapted to the shape and size of the first mounting portion 21, so that the first mounting portion 21 can be smoothly inserted into the first mounting hole 11, and the second interior decoration part 20 is formed with a second mounting hole 22, the third interior decoration part 30 and the second interior decoration part 20 are stacked, and the third interior decoration part 30 is located on the side of the second interior decoration part 20 away from the first interior decoration part 10, the third interior decoration part 30 is toward the second mounting portion 31 protruding from the first interior decoration part 10, the shape and size of the second mounting hole 22 can be adapted to the size and shape of the second mounting portion 31, so that the second mounting portion 31 can be smoothly inserted into the second mounting hole 22.
[0031] The second mounting part 31 is fixedly connected to the first interior trim part 10. The second mounting part 31 and the first interior trim part 10 are fixedly connected by hot rivet welding, or fasteners may be connected between the second mounting part 31 and the first interior trim part 10 to fixedly connect the second mounting part 31 and the first interior trim part 10. At least one of the first interior trim part 10 and the second mounting part 31 is fixedly connected to the first mounting part 21. For example, the first interior trim part 10 is fixedly connected to the first mounting part 21, or the second mounting part 31 is fixedly connected to the first mounting part 21, or both the first interior trim part 10 and the second mounting part 31 are fixedly connected to the first mounting part 21, as long as at least one of the first interior trim part 10 and the second mounting part 31 is fixedly connected to the first mounting part 21. In this application, the case where both the first interior trim part 10 and the second mounting part 31 are fixedly connected to the first mounting part 21 is taken as an example for illustration. And both the first interior trim part 10 and the second mounting part 31 can be fixedly connected to the first mounting part 21 by hot rivet welding, or fasteners may be connected between the first interior trim part 10 and the first mounting part 21 to fixedly connect the first interior trim part 10 and the first mounting part 21, and fasteners may be connected between the second mounting part 31 and the first mounting part 21 to fixedly connect the second mounting part 31 and the first mounting part 21. Taking the case where both the first interior trim part 10 and the second mounting part 31 are fixedly connected to the first mounting part 21 by welding as an example for illustration, it can enable the second interior trim part 20 to participate in hot rivet welding, so that the second interior trim part 20 is effectively fastened, thereby reducing the risk of loosening of the second interior trim part 20, and further improving the durability of the interior trim assembly 100. And by hot rivet welding to achieve the fastening of the interior trim assembly 100, compared with the fastening methods of screwing and ultrasonic welding, the degree of automation of the hot rivet welding process is high, which can significantly improve the production efficiency and assembly accuracy, reduce the production cost of the interior trim assembly 100, and can also reduce additional fasteners and connectors, which is beneficial to the lightweight of the interior trim assembly 100 and conforms to the energy-saving and emission-reduction trend of vehicle design.
[0032] Further, as Figures 3-5 shown, when the first mounting part 21 passes through the first mounting hole 11 and the second mounting part 31 passes through the second mounting hole 22, by heating the first mounting part 21 and the second mounting part 31, the ends of the first mounting part 21 and the second mounting part 31 away from the third interior trim part 30 are quickly melted and form a "mushroom-shaped" structure as Figure 5 shown. After melting, both the first mounting part 21 and the second mounting part 31 are cured and connected to the first interior trim part 10 to form a firm connection, so that the first interior trim part 10, the second interior trim part 20, and the third interior trim part 30 all participate in hot rivet welding, thereby reducing the risk of loosening of the second interior trim part 20, and further improving the durability of the interior trim assembly 100.
[0033] The interior component 100 of a vehicle according to an embodiment of the present utility model is such that the first mounting portion 21 passes through the first mounting hole 11, the second mounting portion 31 passes through the second mounting hole 22, the second mounting portion 31 is fixedly connected to the first interior component 10, and both the first interior component 10 and the second mounting portion 31 are fixedly connected to the first mounting portion 21. When hot riveting and welding the interior component 100, the second interior component 20 can be made to participate in the hot riveting and welding, so that the second interior component 20 can be effectively fastened, thereby reducing the risk of loosening of the second interior component 20, further improving the durability of the interior component 100, and also shortening the production process of the interior component 100 and reducing the production cost of the interior component 100.
[0034] In some embodiments of the present utility model, as Figure 4 shown, the outer peripheral wall of the first mounting portion 21 abuts against the inner wall of the first mounting hole 11, which helps to stably connect the second interior component 20 and the first interior component 10, reducing the risk of loosening or falling off between the second interior component 20 and the first interior component 10 due to vibration, impact, etc. during the use of the interior component 100, also helping to improve the accuracy of the relative position between the second interior component 20 and the first interior component 10, and enabling the second interior component 20 to provide a stable supporting effect on the first interior component 10, further improving the durability of the interior component 100 and effectively extending the service life of the interior component 100.
[0035] In some embodiments of the present utility model, as Figure 4 and Figure 5 shown, the outer peripheral wall of the second mounting portion 31 abuts against the inner wall of the second mounting hole 22, which helps to stably connect the third interior component 30 and the second interior component 20, reducing the risk of loosening or falling off between the third interior component 30 and the second interior component 20 due to vibration, impact, etc. during the use of the interior component 100, also helping to improve the accuracy of the relative position between the third interior component 30 and the second interior component 20, and enabling the third interior component 30 to provide a stable supporting effect on the second interior component 20, further improving the durability of the interior component 100 and effectively extending the service life of the interior component 100.
[0036] In some embodiments of the present utility model, as Figure 4 and Figure 5As shown, the central axes of the first mounting hole 11 and the second mounting hole 22 coincide, which can ensure the precise positioning between the first interior component 10 and the second interior component 20, is conducive to improving the stability and reliability of the interior component 100, and also provides convenience for the installation and adjustment of the first interior component 10 and the second interior component 20, enabling the installer to easily determine the relative positions of the first interior component 10 and the second interior component 20, reducing the need for precise measurement and adjustment, and thus being able to reduce the assembly difficulty of the interior component 100 and being conducive to shortening the production process of the interior component 100.
[0037] In some embodiments of the present invention, as Figure 4 and Figure 5 shown, the shape of the first mounting portion 21 can be adapted to the shape of the first mounting hole 11 to ensure that the first mounting portion 21 can be accurately and firmly mounted in the first mounting hole 11. Further, the shape of the first mounting portion 21 can be cylindrical, and the shape of the first mounting hole 11 can be circular, so that the first mounting portion 21 can be accurately and firmly mounted in the first mounting hole 11, and the diameter of the first mounting hole 11 can be slightly smaller than the diameter of the first mounting portion 21, so as to form an interference fit between the first mounting portion 21 and the first mounting hole 11, which can increase the fastening property and anti-vibration property between the first mounting portion 21 and the first mounting hole 11, and thus can further improve the durability of the interior component 100.
[0038] In some embodiments of the present invention, as Figure 4 and Figure 5 shown, the shape of the second mounting portion 31 is adapted to the shape of the second mounting hole 22 to ensure that the second mounting portion 31 can be accurately and firmly mounted in the second mounting hole 22. Further, the shape of the second mounting portion 31 can be cylindrical, and the shape of the second mounting hole 22 can be circular, so that the second mounting portion 31 can be accurately and firmly mounted in the second mounting hole 22, and the diameter of the second mounting hole 22 can be slightly smaller than the diameter of the second mounting portion 31, so as to form an interference fit between the second mounting portion 31 and the second mounting hole 22, which can increase the fastening property and anti-vibration property between the second mounting portion 31 and the second mounting hole 22, and thus can further improve the durability of the interior component 100.
[0039] In some embodiments of the present invention, as Figure 4 and Figure 5 shown, the second mounting portion 31 can be annular to form a heat conduction hole 32.
[0040] Among them, after the interior component 100 is assembled, the first interior part 10, the second interior part 20, and the third interior part 30 are welded and fixed by hot riveting welding. Specifically, by heating the first mounting portion 21 and the second mounting portion 31, the ends of the first mounting portion 21 and the second mounting portion 31 away from the third interior part 30 are quickly melted and form a "mushroom-shaped" structure as shown in Figure 4 . After melting, both the first mounting portion 21 and the second mounting portion 31 are fixedly connected to the first interior part 10 to form a firm connection. The second mounting portion 31 is configured as a ring to form a heat conduction hole 32. When heat is transferred to the second mounting portion 31 through the welding point, the heat can be diffused to the entire ring structure through the heat conduction hole 32, thereby achieving more efficient heat transfer. It can also make the heat evenly distributed on the entire ring structure of the second mounting portion 31, which helps to improve the strength and reliability of the welding, and can also reduce the temperature gradient during the welding process, reducing the risk of welding deformation and cracks.
[0041] In addition, during the hot riveting welding process, due to the high temperature at the welding point, thermal stress will be generated in the second mounting portion 31. The ring-shaped second mounting portion 31 helps to dissipate the heat to a larger area, thereby reducing the concentration of local thermal stress. The heat conduction hole 32 can also serve as a buffer for thermal expansion, allowing the second mounting portion 31 to have a certain expansion space when heated, further reducing the damage of thermal stress to the interior component 100, and thus improving the stability, reliability, and durability of the interior component 100, and can also effectively extend the service life of the interior component 100.
[0042] In some embodiments of the present invention, as shown in Figure 4 and Figure 5 , the first interior part 10 has a first assembly portion 12, the second interior part 20 has a second assembly portion 23, the third interior part 30 has a third assembly portion 33. The first assembly portion 12, the second assembly portion 23, and the third assembly portion 33 are stacked, and the second assembly portion 23 is in contact with both the first assembly portion 12 and the third assembly portion 33. The first assembly portion 12 is formed with a first mounting hole 11, the second assembly portion 23 is formed with a first mounting portion 21, and the third assembly portion 33 is formed with a second mounting portion 31.
[0043] Among them, the first assembly part 12, the second assembly part 23, and the third assembly part 33 are stacked. When the second assembly part 23 is in contact with both the first assembly part 12 and the third assembly part 33, the first installation part 21 is installed in the first installation hole 11, and the second installation part 31 is installed in the second installation hole 22, which can make the first interior trim part 10, the second interior trim part 20, and the third interior trim part 30 form a stable whole, thereby improving the stability of the interior trim assembly 100. Then, by thermally riveting and welding the first installation part 21 and the second installation part 31 to tightly connect the first interior trim part 10, the second interior trim part 20, and the third interior trim part 30, the interior trim assembly 100 can be effectively fastened, and thus the durability of the interior trim assembly 100 can be improved.
[0044] The vehicle according to the embodiment of the present invention includes the interior trim assembly 100 of the vehicle in the above embodiment, which can enable the second interior trim part 20 to participate in thermally riveting and welding, so that the second interior trim part 20 can be effectively fastened, thereby reducing the risk of loosening of the second interior trim part 20, further improving the durability of the interior trim assembly 100, and also shortening the production process of the interior trim assembly 100 and reducing the production cost of the interior trim assembly 100.
