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

Embodiment Construction

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0027] like figure 1 , figure 2 and image 3 As shown, an automobile wiper includes a wiper arm 1 and a wiper blade 2. The wiper arm 1 includes a main support arm, a plurality of auxiliary support arms and an arcuate support arm, and the auxiliary support arms are respectively hinged on the main support arm. At the end of the arm, the two ends of the auxiliary support arm are respectively hinged with arcuate support arms, and the arcuate support arms are used to fix the wiper blade 2 . A pressure sensor is arranged between the arcuate support arm and the auxiliary support arm, and a t...

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. Background technique [0002] Generally speaking, wipers are used to remove foreign objects or rain and snow after the car is parked or while driving, to prevent foreign objects or rain, snow, etc. from obstructing the driver's front view, and to keep the window glass clean and tidy. In the existing wiper structure, a plurality of arcuate support arms are combined on the rubber wiper blade, and the arcuate support arms are supported by a pair of auxiliary support arms, and the auxiliary support arms are connected to each other through the main support arms. The working process is that the drive motor of the wiper drives the connecting rod device or deceleration device connected with the wiper arm, so that the rubber wiper blade performs repeated reciprocating motion in a fan shape. [0003] However, in real life, when a vehicle is...
