[0050] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0051] Reference below Figure 1-15 The middle frame 100 of the vehicle-mounted display screen 200 according to an embodiment of the present invention is described.

[0052] Reference Figure 1-Figure 7 As shown, the middle frame 100 of the vehicle display screen 200 of the first embodiment of the present invention includes: a middle frame body 10 and a decorative component 20. The decorative component 20 is connected to the outer circumference of the middle frame body 10, and the decorative component 20 is a non-metallic structural component.

[0053] Specifically, the exterior surface of the front side of the middle frame of a traditional in-vehicle display often requires strict surface treatment to increase gloss and feel. However, the exterior surface of the front side of the middle frame is a metal surface. Due to its physical properties, the metal middle frame has poor adhesion and is difficult to spray. It often requires multiple pre-treatment steps such as etching and cleaning. In addition, the metal surface is very hot after exposure to the sun, which may cause harm to the user.

[0054] Therefore, it is necessary to optimize the design of the middle frame 100 of the vehicle-mounted display screen 200. The middle frame 100 of the vehicle-mounted display screen 200 is mainly composed of a middle frame body 10 and a decorative part 20. The decorative part 20 is connected to the outer circumference of the middle frame body 10. Moreover, the decorative part 20 is a non-metallic structural part. In this way, the decorative part 20 can not only decorate the middle frame 100, but also be easy to spray, thereby increasing the adhesion of the surface of the decorative part 20, and also improving the gloss and texture of the middle frame 100. In this way, the decorative part 20 has the advantage of high appearance gloss and can also increase the corrosion resistance and service life of the middle frame 100.

[0055] Also, such as Figure 2 As shown, the decorative member 20 is connected to one side of the outer circumference of the middle frame body 10. For example, the decorative member 20 is provided at least at the bottom of the front side of the middle frame body 10, that is, below the middle frame body 10. In this way, the surface of the bottom of the front side of the middle frame body 10 has a high gloss and texture, and the corrosion resistance and service life of the bottom of the front side of the middle frame body 10 can also be improved.

[0056] Therefore, the arrangement of the decorative part 20 in the middle frame 100 of the vehicle-mounted display screen 200 can not only play a decorative role, but also facilitate spraying, thereby increasing the adhesion of the surface of the decorative part 20, improving the glossiness and texture of the middle frame 100, and increasing the corrosion resistance and service life of the middle frame 100.

[0057] According to some embodiments of the present invention, the decorative component 20 is a plastic structural component, and / or the middle frame body 10 is a metal structural component.

[0058] The decorative component 20 is configured as an integrally injection-molded plastic structural component. The plastic structural component can be easily molded and can also avoid stamping the middle frame 100 , which can be replaced by the decorative component 20 , thereby reducing the number of steps.

[0059] In addition, the plastic structural member can have a high gloss and texture, thereby avoiding the need for surface treatment of the exterior surface of the middle frame 100. Moreover, the surface of the plastic structural member has a high adhesion, thereby facilitating spray painting.

[0060] The plastic structural part is a composite structural part of PC (polycarbonate) and ABS (a copolymer of acrylonitrile (A), butadiene (B) and styrene (S)). Thus, the plastic structural part has high impact resistance, heat resistance and hardness.

[0061] Furthermore, the middle frame body 10 is a metal structural part. The metal middle frame body 10 has good thermal conductivity and can facilitate heat dissipation, thereby preventing the display screen from being affected by overheating. In addition, the non-metallic decorative parts 20 can effectively isolate the heat of the metal, thereby avoiding the problem of the middle frame 100 being hot after exposure to the sun.

[0062] For example, the middle frame body 10 is set as a magnesium alloy structural part, which is formed by die casting and passivated on the surface. It has light weight, high strength, good heat dissipation, high production efficiency and precision. The middle frame body 10 can improve wear resistance and corrosion resistance through passivation treatment, thereby extending the service life of the parts. The middle frame body 10 can also be set as other metal structural parts.

[0063] In addition, the middle frame 100 is provided with a groove, thereby improving the strength and vibration resistance of the middle frame 100. The bottom of the middle frame 100 adopts an integrated mold design, which is stronger and easier to install than a split design.

[0064] According to some embodiments of the present invention, a spray coating is provided on the surface of the decorative element 20 .

[0065] Among them, the spray coating on the surface of the decorative part 20 is a UV layer, that is, an ultraviolet curing coating. In this way, the surface of the decorative part 20 has good wear resistance, which can effectively avoid scratches and wear during daily use, thereby extending the service life of the middle frame 100.

[0066] Furthermore, the spray coating is configured as a UV layer, which can provide high gloss and transparency, and the UV layer can form good adhesion with a variety of substrates (such as metals), thereby ensuring the durability of the coating.
