Description

Windshield wiper adhesive tape

Technical Field

The utility model relates to an auto-parts indicates especially to relate to a windshield wiper adhesive tape accessory suitable for wiper.

Background

As shown in fig. 1, the width of the bottom 1a of the wiping part of the common wiper rubber strip in the current market is generally 0.6mm-1mm, and when the wiper blade wipes, the wiping part of the wiper rubber strip is easy to press and deform, which reduces the cleanliness of the wiper blade; meanwhile, the manufacturing of the windshield wiper rubber strip is often made through an extrusion molding process, as shown in fig. 2, the extrusion molding rubber strip is two rubber strips A, B which are mirror images of each other along the bottom end of the wiping part, the two rubber strips are cut off and separated through two cutters 2a positioned at the bottom end of the wiping part, and the width of the bottom of the wiping part 1a is small, so that the depth of the left and right cutters cut off the wiper rubber strip is prone to deviation, unevenness exists at the bottom of the wiping part 1a of the windshield wiper rubber strip, and finally the cleanliness of the wiping of the rubber strip can be influenced.

In view of the above, the present inventors have made extensive studies on the above-mentioned drawbacks of the prior art, and have made this invention.

Disclosure of Invention

An object of the utility model is to provide a scrape effectual windshield wiper adhesive tape of brush.

In order to achieve the above object, the utility model discloses a novel windshield wiper adhesive tape, windshield wiper adhesive tape top-down includes fixed part, rocking arm respectively and scrapes brushing portion, the fixed part be used for fixing windshield wiper adhesive tape on the support of boned windshield wiper or on the shell fragment of boneless wiper, the rocking arm be used for connecting the fixed part and scrape brushing portion, ensure to scrape brushing portion can be for fixed part lateral oscillation. The width of the bottom edge of the scraping and brushing part, which is used for being in contact with the surface of the windshield glass, is Y, Y is more than 1mm and less than or equal to 5mm, two ends of the bottom edge extend upwards to form two side edges, the tops of the two side edges are connected with the bottom of the rocker arm to form a closed body, and the bottom edge and the two side edges form a first scraping edge and a second scraping edge respectively.

Based on above-mentioned design, because the width on scraping brush portion base is obviously greater than the width on traditional windshield wiper adhesive tape base, the windshield wiper adhesive tape is when scraping the brush, and it is difficult to push down the deformation to scrape brush portion for first sword and the second of scraping is scraped the sword and can is contacted each other with windshield's surface all the time, and its cleanliness factor of scraping the brush is better.

Further, scrape brush portion fretwork, this fretwork portion link up around following windshield wiper adhesive tape length direction, and this design can increase the brush portion elastic deformation volume of scraping of windshield wiper adhesive tape, and at scraping the brush in-process, it scrapes the elastic deformation of brush portion for the first sword of scraping can fast switch over with the second sword of scraping, further promotes its cleanliness factor of scraping the brush and is in.

Furthermore, the tops of two side edges of the wiping part extend outwards along the horizontal direction of the bottom of the rocker arm to form horizontal extension sections, the included angle between each horizontal extension section and the corresponding side edge is larger than or equal to 90 degrees, and the angle range of the transverse swing of the wiping part of the rubber strip of the windshield wiper is enlarged.

The rubber strip fixing part and the rocker arm are made of a first rubber material, the scraping and brushing part is made of a second rubber material, and the first rubber material and the second rubber material are jointly and integrally extruded and molded; this second rubber material can choose for use that the cost is higher, hardness and toughness are moderate, scrapes the effectual material of brushing, avoids whole windshield wiper adhesive tape all to adopt the same material, reduction in production cost.
