Three-scraper round hole inner support windscreen wiper rubber strip supported by flexible walls

Abstract

The invention relates to a three-scraper round hole inner support windscreen wiper rubber strip supported by flexible walls. Windscreen wiper rubber strip fixing clamping grooves (2) are formed in the upper portion of the windscreen wiper rubber strip (1), and scrapers (6) are arranged on the lower portion of the windscreen wiper rubber strip (1). The windscreen wiper rubber strip is characterized in that two tubular cavities are formed in parallel in bottom plates (3) of the windscreen wiper rubber strip fixing clamping grooves (2) in a bilateral symmetry mode in the axial direction of the windscreen wiper rubber strip (1) and comprise the left cavity (17) and the right cavity (16), the left flexible wall (4) and the right flexible wall (5) and a middle partition wall (12) are formed, and the bottom plates (3), the left cavity (17) and the right cavity (16) form a flexible wall supporting structure (7); the left scraper (10), the right scraper (11) and the middle scraper (14) are arranged in parallel at the lower ends of the two sides of the bottom plates (3) in the axial direction of the flexible wall supporting structure (7) respectively. The three-scraper round hole inner support windscreen wiper rubber strip has the advantages that under the supporting of the flexible supporting structure, the fitting degree of the scrapers is higher, the cleaning degree is higher, and the three-scraper efficiency is higher.

Description

Technical field [0001] The invention relates to a wiper rubber strip for a wiper, which belongs to the field of automobile wipers, in particular to a wiper blade supported by a flexible wall of three blades, which can better adapt to the change of the curved surface of the windshield, increase the degree of fit, and improve the cleanliness of the wiper degree and scraping efficiency. Background technique [0002] At present, the support platform of the wiper blade of the wiper rubber strip on the market is usually rigid. Since the windshield glass is a curved surface shape, coupled with manufacturing reasons and wear and tear during use, the surface of the windshield glass is irregular and defective. Under the rigid support It is difficult for the scraper to adapt to the change of the surface of the windshield, and there is only one scraper. The scraping degree is low during the scraping process, and the scraping efficiency is poor. Contents of the invention [0003] In o...
