Transversely-wiping type windscreen wiper

Abstract

The invention provides a transversely-wiping type windscreen wiper and relates to a device for removing dirt such as rain, snow and dust obstructing the view of a user on a windscreen. According to the transversely-wiping type windscreen wiper, a dead corner of wiping and sweeping is avoided and the phenomenon that rainwater follows the wiper is effectively avoided. The transversely-wiping type windscreen wiper comprises a windscreen wiper blade vertically arranged on the surface of a windscreen and making contact with the windscreen, an upper sliding rail and a lower sliding rail. The upper end of the windscreen wiper blade is connected with an upper sliding block arranged on the upper sliding rail and the lower end of the windscreen wiper is connected with a lower sliding block arranged on the lower sliding rail. The transversely-wiping type windscreen wiper is characterized in that the upper sliding rail and the lower sliding rail are respectively a groove-shaped sliding rail, a barrier is arranged in each groove-shaped sliding rail in the length direction of the sliding rail, each groove-shaped sliding rail is divided into an inner groove and an outer groove through one barrier, the middle of each inner groove and the middle of the corresponding outer groove are communicated, at least two idler wheels are arranged in the grooves in the length direction of the sliding rails, and a wheel shaft of each idler wheel is parallel to the corresponding barrier.

Description

technical field [0001] The invention relates to a device for removing dirt such as rain, snow, dust and the like on the windshield, and particularly relates to a horizontal wiper wiper. Background technique [0002] Wiper, scientific name wiper (WINDSHIELD WIPER), refers to the sheet structure installed in front of the windshield, and its main function is to remove rain, snow, dust, etc. on the windshield that hinder the line of sight. Because most of the existing wipers wipe off rain, snow, dust, etc. by fanning the surface of the windshield, there are disadvantages such as limited range of wiping, leaving dead angles that cannot be scraped, and rain following the phenomenon of scraping. Therefore Chinese patent application CN102632868A discloses a kind of horizontal wiper vehicle wiper: "comprising wiper, transmission gear, it is characterized in that: also comprise upper slide rail, lower slide rail, upper slider, lower slider, transmission bead chain, guide pipe , fixin...

AI Technical Summary

Problems solved by technology

Because most of the existing wipers wipe off rain, snow, dust, etc. by fanning the surface of the windshield, there are disadvantages such as limited range of wiping, leaving dead angles that cannot be scraped, and rain following the phenomenon of scraping. Therefore Chinese patent application CN102632868A discloses a kind of horizontal wiper vehicle wiper: "comprising wiper, transmission gear, it is characterized in that: also comprise upper slide rail, lower slide rail, upper slider, lower slider, transmission bead chain, guide pipe , fixing the base, the upper slide rail is installed near the upper edge of the windshield, and the upper slide rail is close to the windshield; the upper end of the wiper is flexibly connected with the upper slider, and the upper slider is installed on the upper slide rail, The lower end of the wiper is flexibly connected with the lower slider, and the lower slider is fixed on the transmission bead chain, and the transmission bead chain is installed in the circular track formed by connecting the lower rail and the guide pipe; the guide tube of the circular track, the gear and the transmission bead chain There is an opening at the transmission joint; the ring track is installed on a fixed base, the fixed base is installed on the lower edge of the windshield, the fixed base is provided with a dust cover, and the dust cover covers the ring track

"Though this windshield wiper that moves laterally on the surface of the windshield solves the above-mentioned shortcomings of the existing fan-shaped wiper, it also has the following disadvantages: the horizontal wiper is only connected to the lower end of the wiper blade. The power device, the movement of the upper end is driven by the movement of the lower end. In fact, due to the existence of frictional resistance between the upper slider and the upper slide rail, coupled with the non-linear track of the slide rail, this setting will cause the wiper blade to be hindered. As a result, it cannot move smoothly on the surface of the windshield
