Intelligent rain sensing, optical sensing and vibration coupling windscreen wiper

Abstract

The invention discloses an intelligent rain sensing, optical sensing and vibration coupling windscreen wiper. The intelligent rain sensing, optical sensing and vibration coupling windscreen wiper comprises a programmable logic controller (PLC) module, a drive shaft, an optical sensor, a rainwater collecting cup, a swing arm, a vibration sensor, a windscreen wiper frame, a support body, a data base board, a windscreen wiper rubber strip and rain sound sensors, wherein the optical sensor and the rainwater collecting cup are assembled on the drive shaft; the swing arm is arranged on the drive shaft and internally provided with a signal line of a flushing pipe; a connection buckle is arranged at the front end of the swing arm; the connection buckle and a fixing base are assembled; the vibration sensor is arranged in the fixing base; the windscreen wiper frame is integrally arranged below the fixing base and internally provided with the support body, the data base board and the windscreen wiper rubber strip; a rain sound cavity and the rain sound sensors are arranged at the two ends of the windscreen wiper frame; a light-emitting module, a light-emitting component and the rain sound sensors are arranged inside the windscreen wiper frame. The PLC module and the various sensors are coupled, intelligent control over the swinging of the windscreen wiper is achieved, and due to the multiple sets of LED flashing lights, a driver and other vehicles are reminded of safe running.

Description

technical field [0001] The invention relates to the field of wiper technical equipment, in particular to a rain-sensing, light-sensing, vibration-coupling intelligent wiper. Background technique [0002] With the development of science and technology, the automobile industry is also developing rapidly. The car wiper is used to wipe the water or dirt on the car windshield to ensure that the car windshield is clean and bright. The wiper is one of the important parts of the car body , the working principle of the wiper is: when the switch of the wiper is pressed, the motor starts, the speed of the motor is decelerated and increased by the worm gear, and the drive shaft drives the swing arm to swing, and the swing arm drives the wiper to swing left and right through the connecting buckle, and finally the rain The blades wipe the windshield. [0003] Wipers generally use fast gear, slow gear and intermittent control gear. The wipers of some vehicles are also equipped with an el...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, wiper sensor and intelligence are the main development direction, so as to meet the needs of automobile rainproof, cleaning and decontamination, and safe driving. There are deficiencies or defects in the technology: 1. The car wiper system is still in the mechanical age, and the speed adjustment and shifting are not accurate enough to control the amount of rain; 2. The intelligent wiper system is gradually replacing the traditional mechanical wiper. The degree of intelligence is not enough; 3. The form of the sensor is single, and the representativeness of the collected data signal is insufficient
