Problems solved by technology

[0003] At present, the wiper sensor and the wiper controller are produced separately and the linkage between them is poor. In addition, when the wiper body is in use, if the rain suddenly disappears on the front window due to clearing, the wiper body will stop on the front window, which will not only interfere with driving. It is easy to be corroded, and the installation and disassembly of the wiper sensor is also a relatively complicated process, which needs to be simplified, so it needs to be improved

Embodiment Construction

[0022] The present invention will be further described with reference to the accompanying drawings.

[0023] An automotive rain sensor such as Figure 1-Figure 3 As shown, it includes a sensor body 1 and a wiper controller 2 connected to the sensor body 1 through electrical signals. The sensor body 1 includes a housing 3, and one side of the housing 3 is connected with a mounting plate 4. The mounting plate One side of 4 is pierced with two threaded rods 5 threadedly connected with the mounting plate 4, the threaded rods 5 are vertically arranged with the mounting plate 4, and one end of the threaded rods 5 is provided with a connection coincident with the threaded rods 5 axis lines. Rod 6, the part of the connecting rod 6 is in the threaded rod 5, and one end of the connecting rod 6 in the threaded rod 5 is integrally connected with a circular limiting circle 7, and the threaded rod 5 can rotate relative to the limiting circle 7, The circumference of the connecting rod 6 is ...

Abstract

The invention relates to an automobile rain sensor, comprising a sensor body, a wiper controller, a housing, a mounting plate, a threaded rod, a connecting rod, a limit circle, a first limit rod, a sliding groove, and a suction cup. The mounting plate is provided with One side of the suction cup is provided with Velcro, two positioning plates are integrally connected to both ends of one side of the mounting plate, and the two positioning plates are rotatably connected to the same rotating plate, and the rotating plate is connected to the housing. Both ends of the rotating plate are sleeved with torsion springs, one end of the torsion spring is fixedly connected to the positioning plate, and the other end of the torsion spring is fixedly connected to the rotating plate, and the housing is provided with infrared rays at both ends respectively. A transmitting tube and a photosensitive receiving tube for receiving infrared rays, and a microcomputer is also arranged in the middle of the housing. The invention has the advantages of strong linkage between the wiper sensor and the wiper controller, the ability to automatically return the wiper body, and the advantages of convenient installation and disassembly.

Description

technical field [0001] The invention relates to the technical field of vehicle sensors, in particular to a vehicle rain sensor. Background technique [0002] The current automotive rain sensor is hidden behind the front windshield, and it can adjust the action of the wiper according to the amount of rain falling on the glass, thereby greatly reducing the troubles of the driver. The rain sensor does not change the action speed of the wiper with a few limited gears, but adjusts the action speed of the wiper steplessly. It has a light-emitting diode called an LED that is responsible for sending far infrared light, and when the glass surface is dry, the light is almost 100% reflected back, so that the photodiode receives a lot of reflected light. The more rain on the glass, the less light is reflected back, which results in faster wiper action. [0003] At present, the wiper sensor and the wiper controller are produced separately and the linkage between them is poor. In additi...
