Detailed ways

As shown in FIGS. 1 to 5 , a car windshield wiper comprises a windshield wiper body 1 , a cleaning unit for accelerating the flow of rainwater, a scraping unit for cleaning dirt, and a transmission assembly;

Wiper body 1: a long groove 2 is opened inside, a strip 17 is installed inside the long groove 2, and tube holes 18 are opened at equal intervals at the rear end of the wiper body 1, and transmission components are arranged at equal intervals inside the wiper body 1; as shown in Figure 1, after the wiper body 1 is installed, it swings back and forth when wiping, and its rear end can wipe the car windshield and clean up dirt.

Cleaning unit: comprising a worm 5 rotatably connected in the long slot 2, a notch is provided at the lower end of the long slot 2, a cylindrical post 6 is installed at the lower end of the worm 5, the post 6 is placed in the notch, one side wall of the post 6 extends out of the notch, a rotating drum 7 is rotatably connected in the cylinder hole 18, a T-shaped rotating column 8 is slidably connected inside the rotating drum 7, a cleaning cotton plate 9 is installed at the rear end of the T-shaped rotating column 8, a hydrophobic groove 10 is equidistantly provided on the circumference of the cleaning cotton plate 9, a worm wheel 11 meshing with the worm 5 is provided on the rotating drum 7; as shown in Figures 2, 4 and 5, during the reciprocating swing of the wiper body 1, the post 6 is in contact with the windshield of the car The glass contacts the worm 5, which can rotate the worm 5. The meshing of the worm 5 and the worm wheel 11 can cause the corresponding groups of rotating drums 7 to rotate. Since a T-shaped rotating column 8 slides in the coaxial direction inside the rotating drum 7, the rotating drum 7 can rotate synchronously with the T-shaped rotating column 8. At the same time, the T-shaped rotating column 8 rotates with the cleaning cotton plate 9 at its rear end, so as to clean the stains on the windshield of the car. At the same time, during the rotation, the water flow on the windshield enters the drain groove 10, which can be centrifuged out, thereby increasing the kinetic energy of the rainwater when it falls, further improving the efficiency of the falling of rainwater, not easily affecting the line of sight, and having a better effect of wiping the rain.

The scraping unit comprises a plate groove 3 provided on one side of the wiper body 1, and a scraper 4 is equidistantly slidably connected in the plate groove 3. As shown in FIG2 , during the reciprocating swing of the wiper body 1, larger leaves or other impurities can be directly scraped off by the scraper 4.

A positioning groove is arranged on the top of the rotating drum 7 , and a positioning column matching with the positioning groove is arranged on the bottom of the horizontal plate of the T-shaped rotating column 8 , and the positioning column is plugged into the positioning groove; the worm wheel 11 is fixedly arranged on the rotating drum 7 .

The transmission assembly includes an arc groove 12 that passes through the long groove 2 and the plate groove 3. A groove column 13 is provided inside the arc groove 12. An arc bar 14 is provided inside the arc groove 12. An arc hole is provided in the middle of the arc bar 14. The groove column 13 is located in the arc hole. As shown in FIG4, during the process of scraping rainwater, if there is firmly adhered dirt, the rear end of the scraper 4 contacts it and moves forward. Through the movement of the arc bar 14, the T-shaped rotating column 8 can be pushed through the Z-shaped folding plate 15 to move it backward, thereby increasing the force applied to the dirt, improving the cleaning intensity, and further improving the cleaning effect.

The transmission assembly also includes a Z-shaped folding plate 15 that is slidably connected to the inside of the long slot 2. The front end of the T-shaped rotating column 8 is rotatably connected to the Z-shaped folding plate 15, and the Z-shaped folding plate 15 is connected to the strip plate 17 through the elastic member 16. As shown in FIG4, in a natural state, the Z-shaped folding plate 15 can be placed in a front side position (a position close to the front direction of the vehicle after installation) by utilizing the elastic member 16. When the wiper is swung, the cleaning cotton plate 9 that contacts the automobile glass can rotate to wipe the automobile glass. At the same time, the rotation process can centrifugally throw out rainwater by utilizing the drainage groove 10, accelerate the outflow of water, shorten the time that rainwater stays on the automobile glass, and improve the driver's observation effect when driving.

One end of the arc bar 14 is movably connected to the front end of the scraper 4 through the bar shaft, and the other end of the arc bar 14 abuts against the Z-shaped folding plate 15 below the T-shaped rotating column 8. As shown in FIG4, when the scraper 4 moves forward, it can move with one end of the arc bar 14. Due to the restriction of the groove column 13, the other end of the arc bar 14 can apply force to the Z-shaped folding plate 15, (because the front end of the T-shaped rotating column 8 rotates on the Z-shaped folding plate 15), so that the T-shaped rotating column 8 can move backward in an instant without affecting its rotation.

Working principle: When in use, as shown in Figures 1 to 5, after the wiper body 1 is installed, it swings back and forth when wiping. During the reciprocating swing of the wiper body 1, the post 6 contacts the windshield of the car, and the friction between its circumference and the windshield can be used to rotate the worm 5. The meshing of the worm 5 and the worm wheel 11 can be used to rotate the corresponding groups of rotating drums 7. Since there is a T-shaped rotating column 8 sliding inside the rotating drum 7, the T-shaped rotating column 8 can be rotated, and at the same time, the T-shaped rotating column 8 rotates with the cleaning cotton plate 9 at its rear end, so that the stains on the windshield of the car can be cleaned. At the same time, during the rotation process, the water flow on the windshield enters the drain groove 10, which can be centrifuged out, thereby increasing the kinetic energy of rainwater when it falls, further improving the efficiency of rainwater falling, not easily affecting the line of sight, and having a better effect of wiping rain;

As shown in Figure 4, during the process of scraping off rainwater, if there is firmly adhered dirt, the rear end of the scraper 4 contacts it. Since the dirt is protruding and firmly adhered, it will press against the rear end of the scraper 4. At this time, the force exerted by the protruding dirt on the arc strip 14 through the scraper 4 is greater than the force exerted by the elastic member 16 on the arc strip 14 through the Z-shaped folding plate 15, which will cause the scraper 4 to move forward, thereby moving one end of the arc strip 14. Due to the limitation of the groove column 13, the other end of the arc strip 14 exerts force on the Z-shaped folding plate 15 (since the front end of the T-shaped rotating column 8 rotates on the Z-shaped folding plate 15), the T-shaped rotating column 8 can be moved backward in an instant without affecting its rotation, thereby increasing the force applied to the dirt, improving the cleaning intensity, and further improving the cleaning effect. After the firmly adhered dirt, the Z-shaped folding plate 15 can be reset due to the action of the elastic member 16, thereby ensuring the effect of continuously cleaning the firmly adhered dirt.
