First, the rain sensor 640 provided in the present embodiment will be described in detail.

Referring to fig. 7 to 9, in the present embodiment, the rain sensor 640 includes a base 641 and an electrode 642 embedded in the base 641. In the preferred embodiment, the electrode 642 and the base 641 are bonded by vulcanization bonding, and this connection mode can ensure the sealing performance of the connection portion between the electrode 642 and the base 641, and prevent water from penetrating into the sealed cavity from the interface between the two. In other embodiments, the electrode 642 and the base 641 are joined by an interference fit.

The base 641 has elasticity, and is preferably made of rubber, so as to ensure sealing performance. The electrode 642 has a rod shape, and may be a separate metal rod, or may be composed of a metal rod and a lead wire welded to a lower end of the metal rod. The number of the electrodes 642 is two, and the electrodes are positive electrodes and negative electrodes which are arranged at intervals. As the best solution of this embodiment, the rain sensor 640 is only composed of the base 641 and the electrode 642, and the electrode 642 is a single metal rod, so that the entire rain sensor 640 is only composed of a rubber material and a metal material, and the manufacturing cost is reduced to the maximum extent.

The base 641 has an upper end face 6411 and a lower end face 6412 opposite to each other, the lower end face 6412 being exposed to the inside of the sealed cavity c, and the upper end face 6411 being exposed to the outside of the sealed cavity c.

On the other hand, other structures disposed outside the sealing structure, such as the cover 630 located above the chassis upper cover 610, may be supported by the support structure 6414 on the outer peripheral surface 6413, and the cover 630 may support itself on the support structure 6414 by the cover hole 6311 thereon, while the upper end region of the support structure 6414 protrudes into the cover hole 6311, so that the upper end face 6411 of the base 641 is exposed outside the sealed cavity c. By constructing the support structure 6414 on the outer peripheral surface 6413 of the base 641, the rain sensor 640 is clamped tightly against the seal structure, ensuring optimal assembly and reliability of the rain sensor 640.

The support structure 6414 has various alternatives, and may be a support flange continuously extending along the circumferential direction of the outer circumferential surface 6413 of the base 641, the support flange being sheet-shaped or having a certain thickness; alternatively, the support structure 6414 may be composed of a plurality of support portions spaced along the circumference of the outer circumferential surface 6413 of the base 641, and the support portions may be in a column shape, a sheet shape, or other shapes. As a preferable aspect of the present embodiment, the support structure 6414 is a support flange extending along a circumferential direction of the outer circumferential surface 6413, the support flange has a certain thickness, and a water guiding groove extending from an inner edge of the flange to an outer edge is configured on an upper surface of the support flange, and preferably, the water guiding groove linearly extends along a radial direction of the flange. Wherein, the quantity of flange is 1 or 2. When the number of the flanges is 1, the chassis upper cover 610 and the fixing plate 630 press the flanges in the thickness direction of the flanges. When the number of the flanges is 2, the base 641 is supported on the cover hole 6111 of the chassis cover 610 by contacting the lower surface of the flange located below with the chassis cover 610, the cover 630 is supported on the flange by contacting the upper surface of the flange located above, and the gutter is formed on the upper surface of the flange located above.

In this embodiment, the outer peripheral surface 6413 is configured with at least one protrusion 6415 extending in the circumferential direction of the outer peripheral surface 6413 and protruding from the outer peripheral surface 6413, the protrusion 6415 is configured in a ring shape, the protrusion 6415 is located below the support structure 6414, and the at least one protrusion 6415 is disposed at intervals in the height direction of the base 641.

In this embodiment, the periphery of the positive electrode and the periphery of the negative electrode are configured with a plurality of cones attached to the water collecting surface 6416, gaps between the plurality of cones are communicated and jointly form a water storage space, and the water storage space is configured to store water and form a water film connecting the positive electrode and the negative electrode. When raining appears in the top of rain sensor 640, because the cone has pointed end up, this pointed end can destroy the tensile force on raindrop surface, then be difficult for forming the great drop of water of volume on the water collection face, and the raindrop is compelled to scatter rapidly and then forms the water film that can switch on positive electrode and negative electrode to realize triggering fast. In one embodiment, the cone is integrally formed on the water collection surface 6416. In one embodiment, the rain collecting structure is a rain collecting structure formed by connecting a plurality of cones, the rain collecting structure is attached to the water collecting surface 6416, the rain collecting structure is provided with a longitudinal channel for the positive electrode and the negative electrode to pass through, and the positive electrode and the negative electrode pass through the longitudinal channel and further extend out of the upper end face 6411 of the base 641. Preferably, said rain collecting structure is detachably fixed to the water collecting surface 6416 for easy replacement. For example, the rain collecting structure may be caught on the water collecting surface 6416 by the concavo-convex structure. Alternatively, the detachable connection is realized by gluing. Preferably, the pyramid is a triangular pyramid or a rectangular pyramid. The plurality of cones are spaced apart or are contiguous at their bases. There is a gap between the cones, each independent of and forming the gap, i.e. there is no contact between adjacent cones. When the cones are connected into a rain collecting structure, the cones are connected together through a connecting part. Alternatively, there is a gap between the cones, which gap is formed in the case that the bottoms of adjacent cones are in contact with each other. The cones form an integral rain collecting structure, and the connection is realized only through the contacted bottoms. In one embodiment, the density of the tips of the plurality of cones is greater than 100 per square centimeter of the water collection surface 6416. The cone with the density distribution can effectively destroy the surface tension of water drops with the diameter larger than 2 millimeters, so that rainwater can be quickly and uniformly spread when falling on the surface, an even water film is formed on the surface, and the problem of quick triggering is solved.
