Description

Boneless wiper noise reduction adhesive tape

Technical Field

The invention belongs to the technical field of windscreen wiper rubber strips, and particularly relates to a boneless windscreen wiper noise reduction rubber strip.

Background

The windscreen wiper is one of important parts of an automobile, and the windscreen wiper is mainly used for cleaning dust, rainwater and other dirt attached to the windshield of the automobile so as to improve the visibility of a driver and improve the driving safety; the wiper generally comprises a wiping brush and a wiping arm, the wiping brush comprises a wiping brush main body and a wiper rubber strip arranged on the wiping brush, and the performance of the wiper rubber strip plays an important role in the cleaning function of the wiper. The cleaning function of the windscreen wiper is mainly realized by the directional back-and-forth brushing movement of the windscreen wiper on the windscreen, and when the windscreen wiper moves to the initial and extreme positions, the wiping blade strip of the wiper rubber strip can turn over in the opposite direction and then enter the next dragged brushing process. Therefore, during the turning process, the wiper will generate sound of hitting the glass due to the impact and friction. Along with the popularization of automobiles, the requirement of consumers on the comfort of the automobiles is higher and higher, and the requirement of the consumers on the noise is also higher and higher. At present, most of automobiles use the wiper rubber strip with a traditional structure, the rubber strip is soft, however, the inventor thinks that the soft wiper rubber strip can generate regional slapping to a windshield after being overturned in the overturning process of the rubber strip with the structure, and the wiper rubber strip has strong structural rigidity and can generate strong and sharp impact, so that the overturning sound is large, and consumers are dissatisfied. Therefore, the boneless wiper noise reduction rubber strip is designed.

It should be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present disclosure, and thus may include information that does not constitute prior art.
