Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, a novel automobile cleaning mechanism for preventing front glass from being scratched and worn comprises a wiper frame 1, wherein a first arc-shaped groove 101 is formed in the upper portion of the wiper frame 1, a water dripping hole 102 is formed in the middle of the wiper frame 1 and is located right below the first arc-shaped groove 101, a second arc-shaped groove 103 is formed in the lower portion of the wiper frame 1 and is located right below the water dripping hole 102, a rectangular groove 104 is formed in the rear side of the lower end face of the wiper frame 1, a connecting block 2 is fixedly connected to the upper end of the middle of the wiper frame 1, mounting holes 201 are formed in the left and right portions of the middle of the connecting block 2, water inlet grooves 202 are formed in the middle of the connecting block 2 and are located between the mounting holes 201, and the lower ends of the first arc-shaped groove 101 and the water inlet grooves 202 are communicated with. The equal fixedly connected with first base 3 in the lower extreme front portion left and right sides of wiper frame 1, the lower extreme of first base 3 rotates and is connected with first pivot 4, the outside of first pivot 4 is provided with spring 5, the outside fixedly connected with walking roller 6 of spring 5, through-hole 601 has been seted up in the inside of walking roller 6 and at spring 5's position, the outside fixedly connected with rubber packing ring 602 of walking roller 6, spring 5 is high elasticity spring, when having the spot on the glass of plantago, thereby avoid walking roller 6 too to extrude glass, in order to lead to the glass of plantago to be scraped the flower.

The inboard end fixedly connected with auxiliary roller 7 of walking roller 6, the anterior left and right sides of lower extreme of wiper frame 1 and at the equal fixedly connected with second base 8 in the rear side of first base 3, the lower extreme of second base 8 rotates and is connected with second pivot 9, and second pivot 9 is the straight axle to guarantee the rotatability of second pivot 9. The outside fixedly connected with driven roller 10 of second pivot 9, the height that highly is less than second base 8 of first base 3 to guarantee walking roller 6 and plantago glass and contact earlier, thereby the further rotation direction who changes 10 of driven roller,

auxiliary roller

7 and 10 of driven roller have the tooth that suits, thereby guarantee the stationarity of transmission structure motion. The outside of second pivot 9 and be provided with sponge 11 between driven voller 10, the arc curved surface of sponge 11 suits with windscreen wiper frame 1 and plantago glass, and the thickness size of sponge 11 is not even to guarantee to carry out effectual clearance to plantago glass, drip hole 102 all with distribute directly over sponge 11, thereby guarantee to fill water to sponge 11.
