Automobile windscreen wiper

Abstract

The invention provides an automobile windscreen wiper. A plurality of runner pipes (3) are arranged in a wiper arm (1) and a wiper blade (2); one end of each runner pipe (3) is connected with an air pump; the other end is branched into two branch pipes; a plurality of grid pipes are vertically and uniformly arranged on the branch pipes; the branch pipes and the plurality of grid pipes are integrally connected to form an isosceles triangle; an end part of each grid pipe is an inverted conical nozzle; the inverted conical nozzle is formed by sequentially connecting an inverted conical surface, acylindrical surface and an arc surface; and a trapezoidal groove is arranged in the wiper blade (2), a top of the trapezoidal groove is connected with the inverted conical nozzle, the inverted conical nozzle is connected with the atmosphere through the trapezoidal groove, a plurality of pressure sensors are arranged on the wiper arm (1), and a telescopic device (4) is arranged between the wiper arm (1) and a driving motor (5) and can control a distance between the wiper arm (1) and a windshield. The windscreen wiper has beneficial effects that after the windscreen wiper senses a hard foreignmatter, the windscreen wiper can automatically or manually leave the windshield and remove the foreign matter, and the foreign matter is prevented from scratching the windshield.

Description

technical field [0001] The present invention relates to the technical field of wiper blades, and more particularly, to an automobile wiper blade.

Problems solved by technology

[0003] However, in real life, when a vehicle is parked in an open-air parking lot for a long time, there may be sand or hard foreign objects between the wiper and the windshield, or on the windshield, or sometimes the vehicle runs at a high speed and the windshield There will also be some sand or flying insect corpses on the windshield. If you wipe it directly with the wiper, it will easily leave dirt on the wiper. The more you wipe the windshield, the dirtier it will be. Scratches will increase the wear and tear of the vehicle's glass windows and wipers, and shorten the product life
