Technical Field

[0001] This utility model belongs to the technical field of automotive interior parts, and particularly relates to an automotive interior part with a gradient color appearance. Background Technology

[0002] With the rapid development of the automotive industry, consumers' demands for car interiors are no longer limited to basic functionality, but also place greater emphasis on aesthetics, assembly reliability, and user comfort. Currently, interior components such as dashboards often use covers to enhance their visual appeal. However, traditional covers mostly feature a single color design, resulting in insufficient aesthetic appeal and failing to meet diverse aesthetic needs. The connection between the cover and the instrument panel housing relies heavily on fasteners such as bolts and screws, requiring additional drilling processes, increasing processing complexity, and leading to excessively long assembly times and reduced production efficiency. Utility Model Content

The boss part 3 is provided at the four corners of the inner wall of the instrument housing 2 and passes through the cover 1; Fastener 4 is provided through the boss portion 3, and one end of it is attached to the cover 1. The bonding pad 5 is disposed through the fastener 4.

[0017] As can be seen in this embodiment, the cover 1 is located on one side of the instrument housing 2 to cover the outside of the instrument housing 2. The outer surface of the cover 1 is provided with a gradient color film. The gradient color film is made of PET substrate and the surface is formed by vacuum coating process to form a multi-layer gradient color coating with a coating thickness of 5-15μm. It has excellent wear resistance and weather resistance and can maintain the gradient color appearance for a long time without fading or peeling. The boss part 3 is located at the four corners of the inner wall of the instrument housing 2 and passes through the cover 1 to provide an installation base for the fastener 4, ensuring the accurate positioning of the cover 1 and the instrument housing 2. The ends of the cover 1 and the instrument housing 2 abut against each other. The fastener 4 is provided through the boss part 3 and one end of it is attached to the cover 1 to fix the cover 1 tightly to the instrument housing 2. The assembly is simple. The fitting gasket 5 is provided through the fastener 4 to improve the structural stability.

[0018] Example 2: This embodiment provides an automotive interior trim with a gradient color appearance, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0019] The boss portion 3 includes: The first mounting end 6 is fixedly connected to the four corners of the inner wall of the instrument housing 2; The second mounting end 7 is fixedly connected to the top of the first mounting end 6; The first groove 8 is provided between the first mounting end 6 and the second mounting end 7; Fastener 4 includes: Connecting plate 9, the shell cover 1 is attached to the connecting plate 9, and the connecting plate 9 is set through the boss part 3; The mounting block 10 has multiple mounting blocks 10 protruding upward from the periphery of the central opening of the connecting plate 9, and the inner wall of the mounting block 10 is fixedly connected with a mounting step 11 that matches the first groove portion 8.

[0020] As can be seen in this embodiment, the four corners of the inner wall of the instrument housing 2 are fixedly connected to the first mounting end 6. The first mounting end 6 is a cylindrical structure, and its material is the same as that of the instrument housing 2, which is ABS engineering plastic. It is integrally molded by injection molding to ensure structural strength. The top of the first mounting end 6 is fixedly connected to the second mounting end 7. The second mounting end 7 is a conical structure, and its bottom diameter is the same as that of the first mounting end 6. This structural design facilitates the initial positioning and insertion of the fastener 4. A connecting plate 9 is attached to the cover 1, and the connecting plate 9 penetrates through the cover. The boss portion 3 is provided, and the connecting plate 9 is a round or square plate made of PA66 reinforced nylon, which has high strength and good toughness. The center of the connecting plate 9 has a through hole that matches the boss portion. Multiple mounting blocks 10 are provided on the periphery of the central opening of the connecting plate 9. The mounting blocks 10 are evenly distributed along the periphery of the through hole to ensure uniform force. The inner wall of the mounting block 10 is fixedly connected with a mounting step 11 that matches the first groove portion 8. When the fastener 4 is assembled in place, the mounting step 11 is embedded in the first groove portion 8 to achieve a tight fit.

[0021] Example 3: This embodiment provides an automotive interior trim with a gradient color appearance, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0022] The mounting block 10 includes a first fitting end 15 extending laterally and connected to the connecting plate 9 at its lower end, with a thickness that is thinner at the bottom and thicker at the top; and a second fitting end 16 formed by bending longitudinally at the end of the first fitting end 15, with the bend forming a gentle slope and the end being flat.

[0023] As can be seen from this embodiment, the mounting block 10 includes a first fitting end 15 and a second fitting end 16. The first fitting end 15 extends laterally and its lower end is connected to the connecting plate 9. The thickness is set to be thinner at the bottom and thicker at the top. This gradual thickness design gives the first fitting end 15 a certain degree of elasticity, which can be slightly deformed during assembly, making it easy to insert into the boss part 3. At the same time, it can provide a certain pre-tightening force after assembly, enhancing the connection stability. The second fitting end is formed by bending longitudinally at the end of the first fitting end 15. The bend is a gentle slope, and the end is a plane. The gentle slope design makes it easy for the second fitting end 16 to slide along the surface of the boss part 3 during assembly, reducing assembly resistance. The end plane can be tightly fitted with the bottom surface of the first groove part 8 to ensure reliable fixation.

[0024] Example 4: This embodiment provides an automotive interior trim with a gradient color appearance, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0025] The boss portion 3 also includes: The third mounting end 12 is fixedly connected to the top of the second mounting end 7; The second groove 13 is provided between the second mounting end 7 and the third mounting end 12.

[0026] As can be seen from this embodiment, the top of the second mounting end 7 is fixedly connected to the third mounting end 12. The third mounting end 12 is a hemispherical structure. The curved surface design of the hemispherical structure can guide the smooth assembly of the fastener 4 and avoid jamming during the assembly process. A second groove 13 is provided between the second mounting end 7 and the third mounting end 12 for the initial pre-fixing of the fastener 4 and to reduce assembly errors.
