Description
Technical Field
The utility model relates to a wiper for car especially relates to and uses two wiper blade formula wiper blades for car.
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, and under the action of friction force, the scraping blade swings left and right to scrape water drops on the surface of the glass completely. In order to improve the stress area between the connecting piece and the rubber strip, the steel sheet is arranged between the connecting piece and the rubber strip, and when the connecting piece moves, the steel sheet can generate downward partial pressure on the rubber strip, so that the friction force between the scraping piece and the surface of the glass is increased, and the water scraping effect is improved.
Common connecting piece can the symmetry set up two inside levels along the lower knot portion that stretches including disturbing current cover and spout in the below of connecting piece, and what correspond is equipped with the fluting that holds down the knot portion above the spacing portion in adhesive tape both sides, during the equipment wiper piece, with the lower knot portion of the fluting connecting portion below of adhesive tape both sides to insert the adhesive tape along lower knot portion, then insert the steel sheet again, alright in order to accomplish the equipment of wiper piece.
When the single-scraper rubber strip is used, the connecting structure is suitable, the two lower buckling parts on the connecting piece can respectively provide clamping force from the left side and the right side of the rubber strip, and the downward pressure of the scraper is uniform when the scraper swings left and right. However, when the structure is used in a double-blade adhesive tape, because the frictional resistance between the two blades and the glass surface is different when the two blades swing in the same direction, and the blades and the adhesive tape are made of soft materials, the deformation generated in the directions of the left side and the right side of the two blades and the adhesive tape is also different, and the horizontal pressure applied by the lower fastening part from the left side and the right side of the adhesive tape is not enough to balance the deformation of the blades and the adhesive tape, so that the situation that the downward pressure applied to the blade at the rear side in the movement direction is smaller than the downward pressure applied to the blade at the front side when the two blades swing in the same direction occurs, the blades are separated from the glass surface, the wiping capability is reduced, the residual water stain on the glass surface cannot be thoroughly cleaned, and the sight.

The lower surface of each limiting part is an inclined plane, and the lower surfaces of the two limiting parts are symmetrically arranged in a splayed manner. The lower surface of the limiting part inclines downwards, so that the limiting effect on the movement of the scraping blade can be achieved when the rubber strip swings, the scraping blade on the swinging rear side direction is ensured to keep enough friction force on the surface of the glass, and the wiping effect is improved.
The adhesive tape comprises left adhesive tape and right adhesive tape of symmetry, and left adhesive tape is including setting up left side in the connecting piece left side stops portion and left doctor-bar, and right adhesive tape is including setting up right side in the connecting piece right side stops portion and right doctor-bar, and the left side is stopped to be equipped with the spacing portion in a left side on the adhesive tape outside of portion below that stops, stops to be equipped with the spacing portion in a right side on the right side adhesive tape outside of portion below that stops. The rubber strip is formed by combining the left rubber strip and the right rubber strip which are symmetrical, so that the manufacturing difficulty of the rubber strips can be simplified, and the large-scale manufacturing is facilitated.
And a left steel sheet is arranged between the connecting piece and the left rubber strip, and a right steel sheet is arranged between the connecting piece and the right rubber strip. The contact area between the steel sheet and the rubber strip is increased, and the pressure applied by the connecting piece is more uniformly distributed on the rubber strip.
The connecting piece is a flow disturbing sleeve or a sliding chute. The structure is various, increases the suitability, is convenient for simply realize the replacement to current product.
The utility model has the advantages that: simple structure can be effectively and even exert pressure to the doctor-bar, ensures that the doctor-bar of motion direction rear side keeps with the contact on glass surface, can effectively clear away remaining water stain, improves the effect of scraping water.
