Detailed Description

Referring to fig. 2, fig. 2 is a schematic view of a wiper blade according to an embodiment of the present invention. The wiper strip 100 according to an embodiment of the present invention has a fixing portion 10, a shoulder portion 20, and a wiper portion 30. The fixing portion 10 fixes the wiper strip 100 to form a wiper blade through the clamping portion 61 (see fig. 4) of the deflector 600, the fixing portion 10 is connected to the shoulder portion 20 through the fixing connecting portion 50, and the shoulder portion 20 is connected to the wiper portion 30 through the supporting portion 40. The fixing portion 10 has a fixing lower surface 11 facing the shoulder portion 20 and a fixing upper surface 12 facing away from the shoulder portion, and the holding portion 61 of the wiper blade deflector 600 contacts the fixing lower surface 11 of the fixing portion 10 and holds the wiper strip 100. The wiper portion 30 has a wiper lip 31 and a support connecting portion 32 connected to the support portion 40, and when the wiper blade operates, the wiper portion 30 swings left and right with the support portion 40 as a fulcrum, and the wiper lip 31 wipes off water or dust of a windshield of the automobile.

According to an embodiment of the present invention, the shoulder part 20 has a first shoulder wing 21 and a second shoulder wing 22, and the first shoulder wing 21 and the second shoulder wing 22 are symmetrically and vertically disposed at both sides of the supporting part 40. The first shoulder wing 21 and the second shoulder wing 22 respectively have a shoulder wing first surface 211 facing the wiper portion 30 and a shoulder wing second surface 212 facing the fixing portion 10. Since the first shoulder wing 21 and the second shoulder wing 22 are symmetrically and vertically disposed at both sides of the support portion 40, the shoulder wing first surface 211 is disposed at a right angle (90 degrees) to the support portion 40. The support connection portion 32 of the wiper portion 30 has a wiper first surface 321 facing the shoulder 20. According to the present invention, the wiping first surface 321 is also disposed at a right angle (90 degrees) to the supporting portion 40. Since the shoulder wing first surface 211 and the wiper first surface 321 are both arranged at right angles (90 degrees) to the support 40, the shoulder wing first surface 211, the wiper first surface 321 and the support 40 are arranged in a horizontal "i" shape. Therefore, when the water wiping strip 100 is manufactured by the compression molding, the angle of the mold is not required to be adjusted, and an operator can more conveniently complete the adjustment of the mold, so that the production efficiency is improved, and the production cost is reduced.

In some embodiments, the shoulder wing second surfaces 212 of the first and

second shoulder wings

21, 22 are also disposed at right angles (90 degrees) to the fixed connection 50. The arrangement can also reduce the adjustment time of the mold and reduce the manufacturing cost of the wiper blade 100. However, when the wiper strip 100 operates with a wiper blade, the wiper portion 30 swings left and right about the support portion 40, and when the wiper portion 30 swings left and right at a large angle, the first shoulder 21 and the second shoulder 22 of the shoulder are pressed, and the first shoulder 21 and the second shoulder 22 deform and move toward the fixing portion 10. After the wiper strip 100 is assembled and fixed to the wiper blade, the fixed lower surface 11 of the fixing portion 10 is provided with the deflector 600 of the wiper blade, and since the gap between the deflector and the second shoulder second surfaces 212 of the first shoulder 21 and the second shoulder 22 is small, and the distance that the first shoulder 21 and the second shoulder 22 can move to the deflector 600 is limited, the angle of the wiper 30 swinging left and right about the supporting portion 40 is limited. When the surface curvature of the windshield is large, the wiping lip 31 of the wiping portion 30 stands on the windshield, and not only is a loud noise generated but also wiping is not clean.

Referring to fig. 3a and 3b in combination, fig. 3a and 3b show a usage state diagram of the wiper strip 100 according to the present invention. In order to increase the angle of the left and right swinging of the water scraping part 30, the present invention further provides some embodiments, the first shoulder wing 21 and the second shoulder wing 22 respectively have a first end 213 connected to the fixing connection part 50 and a second end 214 far away from the fixing connection part 50, and the distance d1 from the first end 213 to the first shoulder wing surface 211 of the second shoulder wing surface 212 is greater than the distance d2 from the second end 214 to the first shoulder wing surface 211 of the second shoulder wing surface 212. As can be seen from fig. 3a and 3b, since the distance from the shoulder wing second surface 212 to the shoulder wing first surface 211 at the second end 214 is reduced, the moving distance of the first shoulder wing 21 and the second shoulder wing 22 to the clamping portion 61 of the guide vane 600 is increased, so that the swing angle of the water scraping portion of the water scraping rubber strip 100 is increased, which can effectively reduce the noise during water scraping and can scrape the windshield glass more cleanly.

In order to increase the working efficiency of the wiper blade, i.e. to reduce the difficulty of adjusting the die set, the present invention provides another embodiment in which the shoulder second surfaces 212 of the first shoulder 21 and the second shoulder 22 are disposed at a right angle (90 degrees) to the connecting portion 50 at the first end 213, and the distance from the shoulder second surface 212 to the shoulder first surface 211 is gradually reduced from 1/3 to 2/3 of the distance from the first end 213.

The utility model also provides some kinds of embodiments, be provided with the recess 121 that runs through fixed upper surface 12 along the lengthwise direction of wiping the adhesive tape in the middle of the fixed upper surface 12 of fixed part 10, the cross section of recess can be V font or U font, certainly can also be other shapes. Since the groove 121 is provided, when the wiper strip 100 is molded, burrs are not formed on the fixing upper surface 12 of the fixing portion 10 due to mold clamping, and thus the assembly of the wiper strip 100 to the wiper blade is more convenient and smooth.

According to an embodiment of the present invention, the wiper strip 100 is made of natural rubber, but may be made of neoprene or epdm. The wiper strip 100 can also be made of silicone.

Referring to fig. 4 and 5 in combination, fig. 4 isbase:Sub>A perspective view ofbase:Sub>A wiper blade withbase:Sub>A wiper strip of the present invention, fig. 5 isbase:Sub>A cross-sectional view taken alongbase:Sub>A-base:Sub>A of fig. 4, it can be seen that the wiper blade hasbase:Sub>A wiper strip 100,base:Sub>A deflector 600,base:Sub>A connecting member 700 andbase:Sub>A steel sheet 800, the deflector 600 clamps and fixes the wiper strip 100, wherein the shoulder portion 20 of the wiper strip 100 hasbase:Sub>A first shoulder wing 21 andbase:Sub>A second shoulder wing 22, and the first shoulder wing 21 and the second shoulder wing 22 are symmetrically and vertically disposed at two sides of the supporting portion 40.
