[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] Please refer to Figure 1-6 In the present device, the side close to the bottom shell 1 is the inner side, and the side close to the panel 4 is the outer side.

[0037] like Figure 1 , Figure 2 , Figure 3As shown, the utility model provides an audio decorative cover for use on a vehicle, comprising: a bottom shell 1, a surface cover 2 arranged on the outside of the bottom shell 1, a decorative cover 3 that can be detachably connected to the bottom shell 1 with the surface cover 2 installed, the decorative cover 3 has a completely penetrating hole 31 on the side facing the bottom shell 1, a panel 4 is provided on the side of the decorative cover 3 away from the bottom shell 1 and can pass through the hole 31 to fit on the surface cover 2, a plurality of grooves 11 are provided at the edge of the bottom shell 1, the surface cover 2 can cover part of the area of ​​the grooves 11, the decorative cover 3 has hooks 32 that match the grooves 11, the hooks 32 can be placed in the grooves 11, and the surface cover 2 can prevent the hooks 32 from falling out of the grooves 11. When assembling the audio decorative cover, first install the bottom shell 1 containing the function buttons. Since the bottom shell 1 is easily damaged, it is necessary to place the cover 2 on the bottom shell 1. At this time, the cover 2 and the bottom shell 1 are not relatively fixed, and the cover 2 can easily fall off the bottom shell 1. Here, it is necessary to fix the cover 2 on the bottom shell 1 by gluing, snap-fitting or using threaded matching. Only when the cover 2 is firmly fixed on the bottom shell 1 can the subsequent components be installed. Then, the side of the decorative cover 3 with the hook 32 is facing the bottom shell 1, and the hook 32 is facing the groove 11 on the bottom shell 1. Press hard, and the decorative cover 3 can be slightly deformed. At this time, the hook 32 moves along the cover 2. After sliding into the groove 11 of the bottom shell 1, the decorative cover 3 recovers from the slight deformation. Since the cover 2 can cover part of the groove 11, the cover 2 also limits the activity range of the hook 32 to prevent the hook 32 from escaping from the groove 11. Since the panel 4 can pass through the hole 31, the panel 4 can be installed last. Glue is applied on the side where the panel 4 needs to be attached to the cover 2, and the panel 4 is aligned to the required position. A positioning block can be set on the panel 4, and a positioning hole matching the positioning block can be set on the decorative cover 3 and / or the cover 2 to assist in positioning. Here, it is appropriate to center all the button holes on the panel 4 with all the button positions on the bottom shell 1. In this way, the installation of the audio decorative cover is completed.

[0038] like Figure 1 As shown, the decorative cover 3 is made of metal, and the thickness of the decorative cover 3 is in the range of 0.3mm-0.5mm. In order to facilitate assembly, the decorative cover 3 needs to be made very thin. Compared with the traditional 0.5mm-1mm metal plate on the market, the thickness of the decorative cover 3 needs to be controlled between 0.3mm-0.5mm, so that the decorative cover 3 can be slightly deformed by pressing, and the hook 32 can slide into the groove 11, while also providing sufficient strength. The thickness of the decorative cover 3 in this embodiment is 0.4mm.

[0039] like Figure 2As shown, as an embodiment, the material of the decorative cover 3 is steel. The reason for choosing steel as the material of the decorative cover 3 is that steel can provide the decorative cover 3 with sufficient strength while not being easy to rust, easy to scrub, and not easy to scratch. At the same time, the cost of using steel is lower than the cost of using aluminum or titanium, which can reduce production costs during mass production. The steel of the decorative cover 3 is specifically made of SUS316. This audio decorative cover needs to be used in transportation vehicles, especially when installed on ships, SUS316 steel is required. Ships sail in rivers, lakes, and seas, and need to face a large amount of moisture, water mist, and water pumped up from the hull, etc. Some of the water contains a large amount of salt and is corrosive. At this time, SUS316 stainless steel is needed to resist corrosion. As another embodiment, the steel of the decorative cover 3 is specifically made of SUS304. SUS304 stainless steel can be used in vehicles such as motorcycles that do not need to be exposed to a large amount of water mist. Although the corrosion resistance and acid and alkali resistance of SUS304 stainless steel are not as good as SUS316 stainless steel, its price is much lower than that of SUS316 stainless steel.

[0040] like Figure 2 As shown, the surface of the decorative cover 3 adopts the wire drawing process. The metal wire drawing process can form clear fine silk marks on the metal surface, making the metal shine with fine hair luster in the matte, which can give people a sense of fashion, technology and modernity. At the same time, there is another surface treatment method, the surface of the decorative cover 3 adopts mirror treatment. The metal mirror process can provide high finish and aesthetics, giving people a noble appearance while maintaining easy cleaning. Different users can choose the decorative cover 3 that suits their aesthetic taste according to their preferences.

[0041] like Figure 4 As shown, the bottom shell 1 is a circular structure, and the number of grooves 11 at the edge of the bottom shell 1 is three, and the spacing between each groove 11 is 120°. There are three grooves 11 at the edge of the bottom shell 1, and the spacing between each groove 11 is 120°. The number of hooks 32 matching the grooves 11 is also three, and the spacing between each hook 32 is also 120°. Here, if the number of grooves 11 and the corresponding hooks 32 is two, it is not conducive to the firmness of the decorative cover 3 on the bottom shell 1. In the case of damage to one hook 32, the decorative belt 3 will fall off the bottom shell 1, which reduces the fault tolerance of the decorative cover 3; if the number of grooves 11 and the corresponding hooks 32 is greater than three, it is difficult to press the hooks 32 of the decorative cover 3 into the grooves 11 when the hooks 32 of the decorative cover 3 are pressed against the surface cover 2, which is not convenient for the installation of the decorative cover 3, which is not friendly to people with weak arm strength. In this embodiment, when the number of hooks 32 of the decorative cover 3 and the corresponding slots 11 is three, it is not easy to be damaged and is convenient to install.

[0042] like Figure 5 , Figure 6 , Figure 7 As shown, the cover 2 is provided with a hook groove 21 for the hook 32 to slide down easily. In order to make it easier to install the decorative cover 3, the cover 2 is provided with a hook groove 21 for the hook 32 to slide down easily. The hook groove 21 reduces the deformation of the decorative cover 3, making it easier for the installer. At the same time, the hook groove 21 also has a guiding function to control the direction in which the hook 32 slides down to prevent the hook 32 from not falling into the groove 11 and causing installation failure. The cover 2 is made of plastic. The plastic cover 2 has a wider deformation, which reduces the deformation of the decorative cover 3 and makes it easier to install the decorative cover 3.
