Background
The wiper device for an automobile includes: the wiper comprises a connecting piece and a rubber strip, wherein the connecting piece is used for connecting the swinging arm, the rubber strip is made of soft rubber materials, and the rubber strip comprises a stop part arranged in the connecting piece and a scraping piece positioned outside the connecting piece. When the swing arm is driven by the motor to swing in a left-right reciprocating mode, the connecting piece drives the rubber strip to move in a left-right reciprocating mode on the surface of the automobile glass. Under the action of friction force, the scraping blade swings left and right to scrape water drops on the surface of the glass clean.
When the double-blade type automobile windshield wiper blade swings left and right in a reciprocating mode, the bottoms of the rubber strips on the left side and the right side swing on the surface of automobile glass in the same direction respectively, and water drops on the surface of the glass are scraped by utilizing the friction force between the bottoms of the rubber strips and the surface of the glass under the pressure of the connecting piece. During each co-directional oscillation, the bottom outside edge of one strip and the bottom inside edge of the other strip will simultaneously contact the glass surface. Because of being two adhesive tape structures, the deformation degree of two adhesive tapes when equidirectional swing is inconsistent, just so leads to being located the resistance that the adhesive tape bottom of swing direction front side received too big, and the resistance undersize that the adhesive tape bottom of swing direction rear side received causes the wearing and tearing of front side adhesive tape bottom too fast, is unfavorable for long-time use, influences its life-span.

The first inner side scraping point part and the second inner side scraping point part are adjacent and are positioned at the inner sides of the double scraping pieces, the first outer side scraping point part and the second outer side scraping point part are positioned at the outer sides of the double scraping pieces, the friction force of the inner side scraping point is greater than that of the outer side scraping point, for example, the right side swinging is taken as an example, the second outer side scraping point part of the right scraping piece is contacted with the glass surface, the second inner side scraping point part is lifted up to leave the glass surface due to the deformation of the right scraping piece, the first inner side scraping point part of the left scraping piece is contacted with the glass surface, the first outer side scraping point part is lifted up to leave the glass surface due to the deformation of the left scraping piece, therefore, only the second outer side scraping point part and the first inner side scraping point part clean the glass surface, the friction force of the second outer side scraping point part is small, the friction force of the first inner side scraping point part is large, so that the second outer side scraping point part of the right scraping piece can only clean the glass, in the one-way swinging process, the dirt on the surface of the glass can be firstly removed, and then the moisture is removed, so that the cleaning effect of the scraping blade is ensured, the structure of the scraping blade is prevented from being damaged too early, and the cleaning service life of the scraping blade is prolonged.
The first inner side scraping tip part and the first outer side scraping tip part are respectively coated on the coating on the bottom surface of the left scraping blade, and the second inner side scraping tip part and the second outer side scraping tip part are respectively coated on the coating on the bottom surface of the right scraping blade. The coating mode is adopted to arrange the scraping tip part, so that the operation is convenient, simple and feasible.
The connecting portion comprises left connecting portion and right connecting portion, and the stop part comprises the left stop portion that sets up on left connecting portion and the right stop portion that sets up on right connecting portion, left doctor-bar is located left stop portion bottom, right doctor-bar is located right stop portion bottom. The adhesive tape is composed of a left part and a right part which are symmetrical, so that the manufacturing difficulty of the adhesive tape is simplified, and the large-scale production is facilitated.
The utility model has the advantages that: the structure of the double scraping pieces can be fully utilized to thoroughly remove stains and water, the service life of the scraping pieces is effectively prolonged, and the sufficient cleaning effect is ensured.
