Embodiment 1

Referring to Fig. 1, the wiper of the present invention comprises a wiper body (not shown), a wiper strip 1, a protective casing 2, and the scraping surface of the wiper strip 1 is a transverse section (along the width of the wiper strip) ) is a curved arc surface, in order to make the scraping surface of the wiper strip 1 curved, the cross section of the wiper strip (in the width direction of the wiper strip) may be circular, elliptical, semicircular For other shapes, the scraping surface of the wiper strip can be a smooth surface (see Fig. 2), or it can be provided with a concave-convex texture on the scraping strip of the wiper strip. The texture can be a dot shape, a strip shape, a cloud shape, etc. Any shape (see Figure 3, Figure 4, Figure 5, cloud), the texture on the scraper surface of the strip reduces the contact surface of the strip with the glass, and each texture can be applied to the dirt adhering to the glass. Repeatedly sweeping, the scraping of the upper and lower rounds is equivalent to the linear scraping of the blade-type (or triangular) wiper glue, which is similar to the repeating and progressive hanging of the multi-blade scraper. The net effect effectively avoids the long-term linearity of the blade-type (or triangular) wiper strip. Dust or debris rubs and is vulnerable, thus effectively preventing the damaged rubber strip from leaving the water mark unclean when it is raining. Referring to Fig. 3, the circular features at the pits of the dot-like texture are less likely to leave dirt; see Fig. 4 and Fig. 5, the strip-shaped and auspicious cloud-like textures have stronger detergency. This type of wiper strip is more resistant to damage than the sheet-shaped wiper strip made of the same material. It has a very small dot-shaped, strip-shaped, auspicious "engraved" design on the surface of the textured scraping surface. For mosquitoes that form short but have formed a slight stick, Bird droppings or other foreign matter, the corners of the shape of the texture scraping surface are formed at an angle with the glass under the pressure of the wiper member, and the upper and lower movement of the wiper arm can "scrape" the foreign matter, and When the blade (or triangle) is scraped, the scraping surface "sleeps" on the glass contact surface, and scratching the surface of the foreign object when scratching the slightly foreign matter has a significant improvement effect.

In order to effectively remove the debris remaining on the scraping surface of the wiper strip, the wiper strip of the invention is further provided with a self-cleaning point for removing debris remaining on the scraping surface of the wiper strip, outside the wiper strip 1 The protective casing 2 is provided with a gap between the protective casing 2 and the wiper strip 1 , and the self-cleaning point is arranged on the protective casing 2.

The card slot 4 is combined with the elastic plate 5, and the protective casing 2 is provided with a positioning groove 6 for the elastic plate 5 to be locked, so that the protective casing 2 is fixed to the outside of the wiper strip 1.

The lower edge of the two sides of the protective casing 2 forms a blade 7 (self-cleaning point), and a gap is provided between the blade 7 and the scraping surface of the wiper strip. When the wiper strip is in operation, the frictional resistance with the glass acts. Next, the wiper strip shakes its head to make its scraping surface contact with the blade for self-cleaning. Protective casing The lower edge of the blade on both sides 7 (self-cleaning point) can be soft silicone or rubber, or it can be a brush or the like. Referring to Figure 8, the wiper strip 1 has a fixed head cover at both ends 8. The outer shape of the fixed head cover 8 matches the protective outer casing 2, and the fixed head cover 8 is sleeved outside the protective outer casing 2.

The inner surface of the protective casing 2 and the surface of the strip have a lubricating layer, and the inner surface of the protective shell and the surface of the wiper strip have a lubricating wear layer, and the lubricating wear layer is one of polytetrafluoroethylene and polyfluoroethylene. The lubricating wear layer on the surface of the wiper strip is the object with the lowest friction coefficient in the solid object, which can greatly reduce the frictional resistance when the wiper moves. The lubrication The layer has a non-stick property at -196 ° C to 250 ° C for foreign matter of almost all molecular structures, and can effectively and effectively clean the scraping surface of the wiper strip under the action of the self-cleaning point.

As a further improvement of the present invention, the front side of the wiper is coated with a luminous effect surface layer, which may be composed of a resin, a glycerin toughening agent, a pigment, a filler, and a luminescent material, and the energy of the light stored during the day is used for the wiper movement at night. A dynamic bright bar is generated, and the dynamic bright light effect can improve the recognition of the driver of the vehicle in the opposite direction, and can improve the safety factor of the driver in the nighttime environment. The wiper strip has an upwardly and forwardly increasing arc surface of the wiper pressure when driving and the light is illuminating in the direction of the interior of the vehicle. The arc surface has an aerodynamic effect. When driving, the oncoming airflow increases the wiper. And the pressure of the wiper strips and the glass; because the wiper is coated with a luminous coating on the upward and forward side, the curved surface can also block the light of the night light of the wiper without observing the line of sight in the vehicle, thereby effectively avoiding the luminous light on the wiper Brightness has a visual impact on the driver.
