Rainstorm high-speed emergency windscreen wiper

Abstract

The invention discloses a rainstorm high-speed emergency windscreen wiper. A first embodiment of the rainstorm high-speed emergency windscreen wiper is provided with an emergency work mode additionally on the basis of an original windscreen wiper, and comprises a swinging arm positioning circuit, a windshield wiper piece drive circuit and a windshield wiper piece reset circuit; and the sequential working of the three circuits enables the windshield wiper pieces to rotate at a high speed in the sight area of a driver. A second embodiment is provided with a normal mode and an emergency mode, wherein the normal mode comprises the steps that pulleys at two ends of a bridge-shaped frame which loads a windshield wiper piece drive motor and the windshield wiper pieces are placed in guide-track grooves in columns A on two sides of a windshield; uplink and downlink drive motors of the bridge-shaped frame drive transmission tooth racks, further the bridge-shaped frame is driven to perform reciprocating uplink and downlink motion, the comprehensive scraping for the windshield by the windshield wiper pieces is completed, and the purpose of comprehensive cleaning is achieved; and the emergency mode comprises the steps that the bridge-shaped frame is positioned at the edge of the sight area of the driver, a windshield wiper piece drive motor drives a passive turbine, so that the windshield wiper pieces rotate at a high speed, and the continuous clearness of the sight area of the driver can be maintained in the rainstorm.

Description

Technical field: [0001] The invention relates to a windshield wiper that can effectively clear the rainwater accumulated on the windshield of an automobile through the high-speed rotation of the wiper blade in heavy rainfall such as heavy rain or extremely heavy rain, and can complete the comprehensive cleaning of the outer surface of the windshield. Background technique: [0002] At present, automobile wipers have been widely used in automobiles, and its technology is very mature. Its application provides drivers with a good view, enabling drivers to avoid the interference of rain, snow, dust, and humid air, and concentrate on nothing else. However, there are still deficiencies in the existing windshield wipers, and its defects are mainly reflected in the inability to scrape off the rainwater on the windshield in time when encountering heavy rain such as heavy rain or heavy rain, thus losing the function it should have. Because The existing wiper works with the base of the...

Problems solved by technology

[0003] In order to solve the disadvantages that the existing wiper can not wipe off the rainwater accumulated on the windshield in time and can not completely clean up the pollution in the rainstorm or even the heavy rainstorm, the present invention provides a new type of wiper. The high-speed rotation of the wiper blades ensures that the driver's vision area is continuously clear when encountering heavy rainfall.

[0006] Embodiment 2: This solution not only solves the problem that the original wiper cannot comprehensively scrape the windshield, but also incorporates the working method of the circular working surface of the wiper blade in Embodiment 1. This embodiment is on the left and right sides of the windshield Two dark grooves are set on the A-pillars on both sides, and each dark groove is equipped with two racks and a guide rail. The rack is parallel to the position of the guide rail. The output shaft of the wiper drive motor is connected. The wiper blade drive motor is installed on a bridge-shaped frame that spans the entire windshield horizontally. The two ends of the bridge-shaped frame are placed on the guide rails of the left and right dark grooves. The strip passes through its end. Since most of the shapes of automobile windshields are small at the top and large at the bottom, the bridge frame adopts a two-stage socket structure. This structure can change its position when the bridge frame reciprocates up and down. Span. There are two wiper blades on the bridge frame. There is a small angle between the wiper blade and the bridge frame. The two wiper blades overlap in the middle of the windshield. When the bridge frame moves up and down, the span The change makes the overlapping length of the two wiper blades also change. This can make the wiper blade work to the bottom of the windshield without leaving a dead angle.
