Flexible wall supporting intra-foam supporting windshield wiper rubber strip with three scraping pieces

Abstract

Disclosed is a flexible wall supporting intra-foam supporting windshield wiper rubber strip with three scraping pieces. A windshield wiper rubber strip fixing clamping groove (2) is formed in the upper portion of the windshield wiper rubber strip (1), and the scraping pieces (6) are arranged on the lower portion. The flexible wall supporting intra-foam supporting windshield wiper rubber strip with the three scraping pieces is characterized in that the two sides of a bottom plate (3) of the windshield wiper rubber strip fixing clamping groove (2) extend downwards to form a left flexible wall (4) and a right flexible wall (5) respectively, and the left flexible wall, the right flexible wall and the two sides of a flexible wall bottom plate (13) arranged at the upper ends of the scrapping pieces (6) are converged to form a hollow flexible wall supporting structure (7). The left scraping piece (10), the right scraping piece (11) and the middle scraping piece (14) parallel with the axial direction of the flexible wall supporting structure (7) are arranged on the two sides and the middle of the lower portion of the flexible wall bottom plate (13) respectively. The flexible wall supporting intra-foam supporting windshield wiper rubber strip with the three scraping pieces has the advantages that the scrapping pieces are better attached to the curved surface of windshield glass under the supporting of the flexible wall supporting structure, and therefore the scraping degree of the scraping pieces is improved, and the scraping efficiency of the three-scraping-piece structure is three times that of a common single scraping piece.

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...
