Detailed Description

The utility model is described in detail below with reference to the figures and specific embodiments. The following examples are carried out on the premise of the technical scheme of the utility model, and detailed embodiments and specific operation processes are given, but the scope of the utility model is not limited to the following examples.

Comparative example 1

The utility model provides a rainfall sensor mounting structure, sets up in the front of the car on the glass inner sheet 3 of windscreen, as shown in figure 1, including preceding shelves support 1 with set up at 1 inboard rainfall sensor 2 of support, 2 tops of rainfall sensor are equipped with jump ring 21, the bottom is equipped with silica gel layer 22, jump ring 21 card is established on support 1 for rainfall sensor 2 of jump ring 21 below compresses tightly and fixes on glass inner sheet 3, and the silica gel layer 22 and the glass inner sheet 3 of rainfall sensor 2 bottom take place to interfere.

The first dimension a represents the distance between the fixing position of the clamp spring 21 and the glass inner sheet 3, the second dimension b represents the interference amount between the silica gel layer 22 and the glass inner sheet 3, and the third dimension c represents the distance between the bracket 1 and the glass inner sheet 3.
