[0022] To make the above objects, features and advantages of this utility model more obvious and understandable, the following will give a detailed description of the specific implementation manners of this utility model with reference to the accompanying drawings of the specification.

[0023] Many specific details are set forth in the following description in order to fully understand this utility model, but this utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of this utility model. Therefore, this utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, this utility model will be described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of this utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0025] Thirdly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that can be included in at least one implementation manner of this utility model. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0026] Embodiment 1

[0027] Refer to Figure 1 - Figure 4 , this embodiment provides a connection and fixing structure between the decorative cover of the vehicle interior rearview mirror and the decorative cover bottom plate, including an assembly component 100. The assembly component 100 includes a snap end 101, a clamping end 102 and a fastener 103. The snap end 101 and the clamping end 102 are cooperated through the fastener 103.

[0028] Furthermore, the fastener 103 includes an extension part 103a and a claw 103b. The extension part 103a is fixedly connected to the middle position of the snap end 101, and the claw 103b is fixedly connected to the top of the extension part 103a.

[0029] Furthermore, the connection part between the extension part 103a and the clamping jaw 103b is a clamping angle 103a-1.

[0030] Furthermore, the angle of the clamping angle 103a-1 is 100 degrees.

[0031] It should be noted that the angle of the clamping angle 103a-1 being 100° can effectively solve the problem of frictional abnormal noise existing after the previous clamping fixation.

[0032] Furthermore, the top of the clamping jaw 103b is set as an arched surface 103b-1, and the width of the arched surface 103b-1 is 9 millimeters.

[0033] It should be noted that the arched surface 103b-1 being designed as an arch can effectively avoid the problem of the end of the clamping jaw 103b scratching the staff during installation. Being designed with a width of 9 mm makes the clamping contact surface larger and solves the problem of insecure fixation.

[0034] Furthermore, a clamping groove 102a is provided on one side of the clamping end 102, and an interference fit between the clamping angle 103a-1 and the clamping groove 102a forms an interference fit groove 103a-1a.

[0035] It should be noted that the clamping groove 102a is designed as a planar structure, which solves the problems of complex die structure of the clamping end product and inconvenient demoulding.

[0036] In addition, the vertical length of the interference fit groove 103a-1a formed between the clamping angle 103a-1 and the clamping groove 102a is 0.15 mm, which can effectively ensure its firmer fixation without loosening.

[0037] Furthermore, inclined surface installation grooves 101a are provided at the tops of the two side baffles of the buckle end 101.

[0038] It should be noted that the inclined surface installation grooves 101a can be engaged with the clamping end 102 to further increase the stability of the clamping end 102.

[0039] Furthermore, a connection frame 102b is fixedly connected to the top of the clamping end 102.

[0040] It should be noted that the connection frame 102b can facilitate the installation between the clamping end 102 and subsequent components.

[0041] During use, first install the clamping end 102 along the inclined surface mounting groove 101a, so that the clamping angle 103a-1 formed at the connection between the clamping claw 103b and the extension part 103a is engaged with the clamping groove 102a opened on one side of the clamping end 102. At this time, the vertical length of the interference fit groove 103a-1a formed between the clamping angle 103a-1 and the clamping groove 102a is 0.15 mm, which can effectively ensure its fixation is more firm without looseness, and can effectively solve the problem of frictional abnormal noise existing after the previous clamping fixation, making the interior rearview mirror garnish fixed to the garnish bottom plate together, so that the garnish does not fall off. This structure is simpler, has high reliability, is more convenient for assembly, and has an anti-misassembly function.

[0042] Embodiment 2

[0043] Refer to Figure 1 - Figure 4 , based on the previous embodiment, this embodiment provides a connection and fixation structure for an interior rearview mirror garnish and a garnish bottom plate of an automobile, in which a plurality of first reinforcing ribs 101b are fixedly connected to the buckle end 101.

[0044] Furthermore, a second reinforcing rib 103a-2 is fixedly connected to the side of the extension part 103a.

[0045] It should be noted that Figure 1 - Figure 4 the structure in is only for reference of mechanical transmission and does not serve as a schematic diagram of the structural proportion of the final product.

[0046] During use, adding the first reinforcing rib 101b and the second reinforcing rib 103a-2 solves the problem of deformation of the clamping claw 103b and the buckle end 101 when installing the clamping claw 103b.
