[0021] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments. Embodiment 1

[0022] The automobile back door switch mounting seat fixing structure of this embodiment is as follows Figure 4 As shown, it is used to be installed on the sheet metal 2 of the rear door of the car, and the sheet metal 2 is provided with a mounting opening at a position corresponding to the mounting seat 1.

[0023] The structure of the mounting seat 1 is as follows Figures 1 to 4 As shown, it includes a base plate 11 whose size is larger than the installation opening and an insert block 12 fixed on the base plate 11 and whose size is smaller than the installation opening, Figure 2 and Figure 3 As shown, the plug block 12 is provided with a clamping block 13 on four outer sides, and the clamping blocks 13 on two opposite sides are symmetrically arranged with each other. The distance between the outer ends of the two symmetrically arranged clamping blocks 13 is greater than the distance between the two corresponding sides of the installation opening. In this embodiment, the middle part of the clamping block 13 is the outer end, and the outer end smoothly transitions to the outer side of the plug block from the upper and lower sides, respectively forming an upper transition portion 131 and a lower transition portion 132, as shown in FIG. Figure 2 As shown; a gap 14 is provided between one end of the clamping block 13 close to the bottom plate 11 and the bottom plate 11.

[0024] Combination Figure 4 and Figure 5 As shown, when in use, the plug block 12 is inserted into the installation port, and the sheet metal 3 at the installation port is guided by the upper transition portion 131 and the elasticity of the matching material, and is embedded in the gap 14 between the clamping block 13 and the bottom plate 11. The clamping block 13 and the bottom plate 11 are respectively abutted against the inner and outer surfaces of the sheet metal 2, so that the mounting seat 1 is firmly installed on the sheet metal 2 of the car back door; similarly, when disassembling the mounting seat, the plug block 12 is pulled out, and the sheet metal 3 at the installation port is guided by the lower transition portion 132 and the elasticity of the matching material, and is separated from the gap 14 to achieve disassembly; the mounting seat fixing structure of this embodiment is simple in structure and easy to install and disassemble. Embodiment 2

[0025] The fixing structure of the automobile tailgate switch mounting base of the present embodiment is basically the same as that of the first embodiment, except that: in the present embodiment, the slope of the upper transition portion 131 is smaller than the slope of the lower transition portion 132. Since the sheet metal 2 is against the lower transition portion 132, the slope of the lower transition portion 132 is increased, which helps to make the connection between the mounting base 1 and the sheet metal 2 more stable.

[0026] In this embodiment, the connection between the upper transition portion 131 and the lower transition portion 132 is a smooth curve, that is, the outer end of the clamping block 13 is arc-shaped, which facilitates the sheet metal 2 to smoothly pass over the outer end of the clamping block 13 during installation and disassembly.

[0027] In this embodiment, the insert block 12 is provided with a plurality of clamping blocks 13 on a relatively long set of outer sides to increase the connection points with the mounting port sheet metal 2 and make the connection more stable.

[0028] Combination Figure 5 As shown, in this embodiment, since the lower transition portion 132 of the clamping block 13 smoothly transitions downward from the outer end to the outer side surface of the plug-in block, the gap 14 formed between the clamping block 13 and the bottom plate 11 gradually becomes smaller in width from top to bottom, and the thickness of the sheet metal 2 is between the maximum and minimum widths of the gap 14, so that when connected, the sheet metal rests on the inclined surface of the lower transition portion 132.

[0029] The contact surfaces between the bottom plate 11 and the sheet metal 2 are provided with grooves 111 on two opposite outer sides, so as to facilitate the insertion of tools such as plastic buckles for operation when disassembling the mounting seat 1 .

[0030] In this embodiment, a mounting groove 15 for mounting a switch is provided in the middle of the bottom plate 11 .

[0031] The utility model solves the problems of the existing tailgate switch mounting base having a complex structure and being inconvenient to install and disassemble, and can also ensure the connection stability with the tailgate sheet metal.

[0032] The technical solutions of the present utility model are not limited to the above-mentioned embodiments, and all technical solutions obtained by equivalent replacement methods fall within the scope of protection required by the present utility model.
