[0002] In recent years, as cars become more and more intelligent, car users pay more and more attention to the atmosphere and texture of car interiors. The interior speaker cover not only has the functions of dust prevention, cleaning and protecting speakers, but also needs to enhance the sound effect of speakers, enhance the atmosphere and sense of technology in the cabin. The lifting speaker covers on the market are mostly single LED lamp beads and plastic optical fibers to achieve the luminous effect, which can only achieve the functions of luminous and color change. The appearance is easy to scratch, the atmosphere is not strong, the lighting effect is single, and the sense of grade is poor. The effect of improving the cabin atmosphere is not ideal. With the enhancement of car users' perception of cabin atmosphere and cabin sound effects, and the pursuit of more and more technological and intelligent cars, multifunctional metal speaker covers have emerged. Metal speaker covers enhance the cabin sound effects, atmosphere lights enhance the cabin atmosphere, and atmosphere lights and cover lifting functions enhance the sense of technology in the cabin. The existing multifunctional speaker covers are mostly single LED lights, and the atmosphere light effect is achieved by LED irradiating the silver electroplated surface reflection. In addition, the existing multifunctional speaker covers have a single lighting function, which only has two functions: color change and light on and off; the atmosphere is not strong during the day, and the appearance is easy to scratch and difficult to repair.

[0023] like Figure 1 As shown, the speaker cover mainly includes an instrument panel 100, a top cover assembly 200, an ambient light assembly 300 and a lifting assembly 400. The surface of the instrument panel 100 is provided with a cover surface 101. The top cover assembly 200 is arranged on the instrument panel 100 and is used to shield the cover surface 101 after being lowered, so that dust protection can be achieved after shielding. Here, after the top cover assembly 200 and the ambient light assembly 300 are assembled, the lifting assembly 400 can realize the lifting and lowering of the speaker cover and the dust protection of the speaker cover.

[0024] like Figure 2 As shown, specifically, the top cover assembly 200 includes a top cover 201 and a cover plate outer enclosure 202. The top cover 201 and the cover plate outer enclosure 202 are bonded together by structural adhesive to form the top cover assembly 200. The lifting and lowering of the top cover 201 can protect the speaker cover from dust.

[0025] The atmosphere light assembly 300 is installed at the lower part of the top cover assembly 200 and is used for emitting light. Here, the atmosphere light assembly 300 mainly includes an atmosphere light cover 301, a cover plate 302, an atmosphere light upper shell 303, a light homogenizing plate 304, a reflective bracket 305, a light source circuit board 306 and an atmosphere light bottom shell 307, wherein the reflective bracket 305 is mainly used to reflect the light emitted by the light source circuit board 306, and the light homogenizing plate 304 mainly functions to make the light emit evenly. The atmosphere light cover 301 is made of PC material and PUR injection molding, and the atmosphere light cover 301 has a crystal effect appearance surface 500 formed by PUR. In this way, through PUR technology, a diamond crystal appearance is achieved, and it has a certain soft scratch self-repair ability. The inner surface of the atmosphere light cover 301 has a PVD layer, and the atmosphere light cover 301 is sequentially connected with the cover plate 302, the light homogenizing plate 304 and the reflective bracket 305. 05 assembly. In the present embodiment, the atmosphere lamp cover 301 and the cover plate 302, the light homogenizing plate 304 and the reflective bracket 305 are assembled by snapping, ultrasonic welding or laser welding. This has the advantages of simple assembly and firm structure. The light source circuit board 306 has a plurality of light sources. The light source circuit board 306 is located between the reflective bracket 305 and the atmosphere lamp bottom shell 307. The plurality of light sources are a plurality of LED lamps 600 with RGB colors. In this way, a plurality of RGB color LED lamps 600 are arranged in a ring shape to achieve the effect of flowing water and color-changing light. The color-changing light makes the cabin atmosphere stronger at night. The assembly consisting of the atmosphere lamp cover 301, the cover plate 302, the atmosphere lamp upper shell 303, the light homogenizing plate 304, the reflective bracket 305 and the light source circuit board 306 is installed on the atmosphere lamp bottom shell 307 by screws so that its overall up and down movement remains consistent.

[0026] In addition, the lifting assembly 400 is arranged at the bottom of the dashboard 100 and is connected to the top cover assembly 200 and the atmosphere light assembly 300. The lifting assembly 400 drives the top cover assembly 200 and the atmosphere light assembly 300 to realize lifting movement on the dashboard 100. Specifically, the lifting assembly 400 includes a lifting motor 401, an upper bracket 402, a lower bracket 403, a first screw rod 404 and a second screw rod 405. The atmosphere light bottom shell 307 is located on the upper bracket 402. Here, the lifting motor 401 is fixed to the side of the inner wall of the dashboard 100 by screws. The first screw rod 404 and the second screw rod 405 are inserted from the lower bracket 403 into the circular hole connecting the upper bracket 402 and the inside of the dashboard 100. In this way, the lifting motor 401 drives the actuator to ensure that the top cover assembly 200 and the atmosphere light assembly 300 realize lifting movement. The output shaft of the lifting motor 401 is connected to the screw rod and drives the screw rod. The rotation of the rod drives the atmosphere light bottom shell 307 to move up and down. In order to prevent the screw rod from moving downward, the bottom of the first screw rod 404 and the second screw rod 405 are fixed by gasket screws. Here, the assembly composed of the atmosphere light cover 301, the cover plate 302, the atmosphere light upper shell 303, the uniform light plate 304, the reflective bracket 305 and the light source circuit board 306 is installed on the atmosphere light bottom shell 307 by screws, and the first screw rod 404 and the second screw rod 405 are connected to the atmosphere light bottom shell 307. In this way, the lifting motor 401 can drive the screw rod to rotate when it is working, and the rotation of the screw rod drives the upper bracket 402 to move. Since the atmosphere light bottom shell 307 is connected and installed with the upper bracket 402, the atmosphere light bottom shell 307 is lifted and lowered, thereby driving the top cover assembly 200 and the atmosphere light assembly 300 to move together, realizing the overall lifting and dustproof protection of the speaker cover.

[0027] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
