The definition scrapes the lateral part of the side position front side that water rubber strip lip part is located the swing direction of advance, the opposite direction that is located the swing direction of advance is the posterolateral part, because it is pressurized on vehicle window glass to scrape water rubber strip lip part, when the swing is advanced, because it is scraped the frictional force effect that water rubber strip lip part received the posterolateral direction, it is scraped the rubber strip lip that water rubber strip lip part and vehicle window glass contact and is produced deformation backward, the front side can stretch (the notch that the rubber strip neck is located the posterolateral part is compressed and is diminished), the backswing is with the reason, but the problem that exists is: when wiping the reverse swing of water rubber strip lip part swing to maximum amplitude, the frictional force direction has become the reversal this moment, and the rubber strip lip deformation of wiping water rubber strip lip part and vehicle window glass contact still original direction and frictional force direction this moment just opposite, during the reverse swing, it is wiped the rubber strip lip part of water rubber lip part and vehicle window glass contact and is changed to opposite direction by original direction under the effect of frictional force in the twinkling of an eye, do not have smooth buffer transition but direct diversion in the twinkling of an eye, can produce very big abnormal sound with vehicle window glass friction.
For this reason, chinese utility model patent grant publication No. CN205086874U discloses a can eliminate and scrape windscreen wiper rubber strip that water rubber strip lip part turned over when turning to and produced huge abnormal sound with preceding fender door window, it includes windscreen wiper rubber strip equipment part and scrapes water rubber strip lip part, it includes the rubber strip lip that is located the top and the rubber strip neck that is located the below to scrape water rubber strip lip part, and windscreen wiper rubber strip equipment part is equipped with smooth slot, be equipped with a plurality of strengthening rib in the rubber strip neck, the strengthening rib upper and lower extreme respectively with foretell scrape water rubber strip lip part and rain and scrape the rubber strip equipment part and link firmly.
In the actual use process, the noise elimination effect is not very good when the wiper rubber strip reverses.
For this reason, the applicant has improved it, has submitted a utility model patent application named "a windscreen wiper anti-overturning adhesive tape" to the national intellectual property office of china, and the present has authorized, and the bulletin number of authorizing is CN209650237U, and it includes windscreen wiper rubber strip equipment part and scrapes water rubber strip lip part, it includes the rubber strip lip that is located the top and the rubber strip neck that is located the below to scrape water rubber strip lip part, and windscreen wiper rubber strip equipment part is equipped with smooth slot, and it is in the both sides face of rubber strip neck is provided with a plurality of cushions at the interval is crisscross respectively. The utility model discloses a crisscross a plurality of buffering muscle that are provided with in the both sides face of rubber strip neck interval respectively, when making the windscreen wiper prevent upset adhesive tape need not the upset when the switching-over, reduce substantially or reduced the upset noise.
However, in the actual use process, the adhesive tape working end of the boneless wiper blade is greatly deformed after being used for a period of time, the low-temperature wiping performance is poor, the overturning noise is large, and the service life of the wiper blade is generally short.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a boneless wiper blade rubber strip, which aims at the problems that the working end of the rubber strip is deformed greatly, the low-temperature wiping performance is poor, the turnover noise is large and the service life of the wiper blade is generally low after the existing boneless wiper blade rubber strip is used for a period of time; the performance of the adhesive tape is greatly improved in low-temperature wiping performance and turnover noise compared with the adhesive tape with a common structure in the market; the rubber strip improves the service life and the low-temperature wiping performance of the wiper blade and reduces the overturning noise of the wiper blade.
The utility model discloses the technical problem that will solve can realize through following technical scheme:
a boneless wiper blade rubber strip comprises a rubber strip body, wherein the upper part of the rubber strip body is a mounting end, the lower part of the rubber strip body is a working end, the mounting end is connected with the working end through a necking part, and the necking part is bent and deformed when the working end wipes glass; when the rubber strip body operates towards the starting direction or operates towards the resetting direction, the top surfaces of the working ends on the left side and the right side of the necking part are in contact with the corresponding anti-turning limiting points of the rubber strip.
In a preferred embodiment of the present invention, the installation end, the working end and the plurality of anti-overturning limiting points are integrated.
Since the technical scheme as above is used, the utility model discloses an on the bottom surface of the installation department of the throat left and right sides, length direction along the adhesive tape body is provided with a plurality of adhesive tape at the interval separately and prevents the upset limit point, increase the work end of adhesive tape and the brush angle of scraping between the glass, make the work end of adhesive tape warp for a short time, when the doctor-bar is long-time stagnant on the glass surface, can alleviate the work end of adhesive tape because the ageing properties that warp and bring descend, and scraping the brush in-process upset noise less, and because the less doctor-bar low temperature of making of the deformation of the work end of adhesive tape cleans the performance better.
