[0002] The wiper strip is an important part of the wiper system. It is located at the front end of the wiper and directly contacts the car windshield. Its main function is to remove rain, dust, snow and other substances on the windshield in rainy days or other situations to keep the driver's vision clear, thereby improving driving safety. The double-sided multi-layer wiper strip refers to a special design on the wiper. This design allows the wiper to have two or more layers of strips to contact the windshield, thereby providing a better cleaning effect. When one layer of the wiper strip is worn or damaged, the wiper strip can be turned over to increase its service life.

[0003] During the use of the existing wiper rubber strip, it is not convenient to use the bone strip structure to maintain the stability of the rubber strip. Under high-speed driving or strong wind conditions, it is easy to cause poor contact between the rubber strip and the windshield, thereby reducing the wiping stability. Utility Model Content

[0007] As a preferred double-sided multi-layer wiper rubber strip of the utility model, grooves are provided on both the upper and lower sides of the rubber strip body, and the grooves are located on the side opposite to the first brush head and the second brush head.

[0008] As a preferred double-sided multi-layer wiper rubber strip of the utility model, a mounting hole is initially formed inside the rubber strip body, and the bone strip mechanism is fixedly installed in the mounting hole.

[0009] As a preferred double-sided multi-layer wiper rubber strip of the utility model, the bone strip mechanism includes an insulating layer, an elastic bone strip is fixedly connected to the inside of the insulating layer, and a heating wire is wound around the surface of the elastic bone strip.

[0010] As a preferred double-sided multi-layer wiper rubber strip of the utility model, the interior of the insulating layer is filled with a thermally conductive filler, and the elastic bone strip and the heating wire are both located in the thermally conductive filler.

[0011] As a preferred double-sided multi-layer wiper rubber strip of the utility model, a plurality of steel wire strips are fixedly connected inside the elastic bone strip.

[0012] As a preferred double-sided multi-layer wiper rubber strip of the utility model, the material of the insulating layer is polyvinyl chloride, and the material of the elastic bone strip is thermoplastic polyurethane.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model uses the first brush head, the second brush head and the third brush head to contact the windshield in sequence to remove moisture or other impurities on the glass surface. The groove can assist in removing excess moisture, reduce the water film effect, and improve the scraping efficiency. The design of the groove helps the rubber strip mechanism to better adhere to the windshield surface and improve the scraping effect. By providing the mounting hole, it is convenient to install the bone strip mechanism. By providing the arc portion, it is convenient to prevent impurities from accumulating on the third brush head.

[0015] 2. The utility model provides necessary supporting force by setting up a bone bar mechanism to ensure that the rubber strip mechanism can maintain good contact on windshields with different curvatures. The elastic bone bars in the bone bar mechanism can provide necessary supporting force to enable the rubber strip mechanism to maintain a stable shape during the wiping process and will not be easily deformed even under high-speed driving or strong wind conditions. The elastic bone bars and the internal steel wire strips enhance the structural strength of the rubber strip mechanism, so that it can still maintain good performance after long-term use and is not easily damaged. The electric heating wire wound inside the bone bar mechanism can heat the rubber strip mechanism in a low temperature environment to prevent frost from adhering to the rubber strip mechanism and maintain its effective operation under cold conditions. By filling the insulating layer with thermal conductive filler, it can be ensured that the heat generated by the electric heating wire can be evenly distributed on the entire rubber strip mechanism to improve the heating efficiency. By setting up an insulating layer, it is convenient to protect the electric heating wire to avoid leakage and damage. BRIEF DESCRIPTION OF THE DRAWINGS
