DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent, obvious and easy to understand, the specific embodiments of the utility model will be explained in detail below with reference to the drawings of the specification.

[0020] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the utility model, but the utility model can also be implemented in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the utility model, therefore, the utility model is not limited by the specific embodiments disclosed below.

[0021] Secondly, the "one embodiment" or "embodiment" referred to herein can include specific features, structures or characteristics in at least one implementation of the utility model. "In one embodiment" appearing in different places in this specification does not refer to the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0022] Embodiment 1

[0023] Referring to Figure 1 and Figure 2 For the first embodiment of the utility model, the embodiment provides a stable noise reduction automobile interior rearview mirror decoration cover, and the stable noise reduction automobile interior rearview mirror decoration cover comprises a positioning installation assembly 1 and a decoration cover assembly 2.

[0024] Through the cooperative design of the positioning installation assembly 1 and the decoration cover assembly 2, the obvious defects such as the complicated secondary process caused by the pasting of the felt, the missing risk and the easy failure are effectively solved, not only the felt pasting link after the production of the decoration cover is saved, the production process is simplified to improve the efficiency, at the same time, the noise reduction failure problem caused by the missing or scratching during assembly is avoided, the artificial and material costs are simultaneously reduced, the design is optimized from the structure integration and the production assembly, not only the manufacturing cost and the process loss are reduced, but also the abnormal sound hidden danger is radically cured through the long-acting noise reduction mechanism to improve the use experience, and key technical support is provided for the production economy and the functional reliability of the automobile interior rearview mirror decoration cover.

[0025] Specifically, the positioning installation assembly 1 comprises a ceiling 11, a first through hole 12 is formed in the surface of the ceiling 11, and a second through hole 14 is formed in one side of the ceiling 11.

[0026] Specifically, the decoration cover assembly 2 is arranged on one side of the positioning installation assembly 1 and comprises a decoration cover main body 21 fixed to one side of the ceiling 11, and a vertical rib structure 27 is fixed to one side of the decoration cover main body 21.

[0027] Embodiment 2

[0028] Referring to Figures 2 to 4 For the second embodiment of the utility model, the embodiment is based on the previous embodiment.

[0029] Specifically, the inner wall of the decorative cover body 21 is fixed with a heat dissipation decorative hole 22, one side of the heat dissipation decorative hole 22 is provided with a first decorative cover assembly buckle 23, and the first decorative cover assembly buckle 23 is fixed to the inner wall of the decorative cover body 21.

[0030] The heat dissipation decorative hole 22 can not only ventilate and dissipate heat for internal components, but also play a decorative role through hole modeling to improve the aesthetic appearance; the first decorative cover assembly buckle 23 can be clamped with a corresponding structure to preliminarily fix the decorative cover body 21 and ensure accurate positioning of the position during installation.

[0031] Specifically, the inner wall of the decorative cover body 21 is fixed with a second decorative cover assembly buckle 25, and one side of the decorative cover body 21 is fixed with a Bluetooth module fixing column 26.

[0032] The second decorative cover assembly buckle 25 cooperates with the first decorative cover assembly buckle 23 to enhance the connection stability of the decorative cover body 21 from different positions and avoid loosening; the Bluetooth module fixing column 26 is used to fix the Bluetooth module so that it is stable in position in the decorative cover body 21 and prevents poor contact due to vibration.

[0033] Specifically, the inner wall of the decorative cover body 21 is fixed with an installation positioning column 24.

[0034] The installation positioning column 24 is inserted into the corresponding positioning hole during installation of the decorative cover body 21 to accurately limit the installation position and avoid deviation or inclination, thereby ensuring the assembly accuracy of the decorative cover body 21 and other components.

[0035] Specifically, the surface of the ceiling 11 is fixed with a fixed buckle 13.

[0036] The fixed buckle 13 cooperates with the assembly buckle of the decorative cover body 21 to realize detachable connection of the ceiling 11 and the decorative cover body 21, which not only ensures firm connection but also facilitates later disassembly and maintenance, thereby improving the assembly flexibility of the overall structure.

[0037] During use, during installation, the decorative cover body 21 of the decorative cover assembly 2 is clamped with the fixed buckle 13 on the surface of the ceiling 11 of the positioning and installation assembly 1 through the cooperation of the first decorative cover assembly buckle 23, the second decorative cover assembly buckle 25 and the installation positioning column 24, which assists positioning, to ensure that the decorative cover body 21 is stably fixed to one side of the ceiling 11, the Bluetooth module fixing column 26 is used to fix the Bluetooth module, and the heat dissipation decorative hole 22 plays a dual role of heat dissipation and decoration.

[0038] During use, the vertical rib structure 27 on one side of the decorative cover body 21 is in contact with the ceiling 11, which changes the original surface contact into line contact between the vertical rib and the ceiling, greatly reduces the friction area, and fundamentally reduces the abnormal noise caused by relative friction between the two when the vehicle bumps.

[0039] The vertical rib structure 27 is kept 0.5mm from the ceiling 11, which can offset the 0.3-0.4mm compression of the ceiling 11 due to vibration during vehicle driving, ensure that the two are always closely attached, avoid the shaking noise caused by too large gap, and ensure the visual flatness and beauty of the joint.

[0040] In addition, the vertical rib structure 27 and the decorative cover body 21 are integrally injection molded by PC+ABS material, without additional assembly parts, avoiding the failure risk of traditional structure such as felt falling off and displacement, ensuring the stable anti-noise effect during long-term use, and the first through hole 12 and the second through hole 14 are reserved for the passage of components such as lines, without affecting the overall function.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced without departing from the spirit and scope of the present application. It should be included in the scope of the claims of the present application.
