Problems solved by technology

[0003] The transmission mode in which rack bars and gears mesh is a common driving structure in automobile wipers, but during long-term use, dust is easy to accumulate in the tooth grooves of the gears. With the accumulation of dust, the rack bars and gears are not fully meshed. , not only affects the normal operation of the wiper, but also the components in the wiper are easily damaged due to uneven force, which affects the service life

specific Embodiment approach

[0043] Specific implementation method: when the drive disk 5 is driven by the drive motor 4 to rotate, the drive disk 5 drives the rack bar 6 to reciprocate, and then the rack bar 6 drives the gear 9 to switch between forward rotation and reverse rotation. During the rotation of the gear 9 The wiper arm 10 drives the support plate 12 to rotate, and then the support plate 12 drives the push block 18 to rotate together. When the push block 18 rotates to the position where the rack bar 6 meshes with the gear 9, the movable magnet 19 overlaps with the fixed magnet 13 , and then under the repulsive effect of the movable magnet 19 and the fixed magnet 13, the push block 18 breaks away from the tooth groove on the gear 9, and the return spring 32 is in a compressed state at this time, when the push block 18 moves away from the rack bar 6 and the gear 9 When the engaged position rotates, the movable magnet 19 and the fixed magnet 13 are staggered, and then under the action of the resil...

Abstract

The invention relates to the technical field of automobile accessories and particularly relates to an automobile windscreen wiper. The wiper comprises a carrier plate, wherein a driving motor is installed on one side face of the carrier plate, an output end of the driving motor penetrates through the carrier plate and is fixedly connected with a driving disc, and the end, away from the driving disc, of a toothed rail strip is meshed with a gear rotationally connected with the carrier plate; a supporting disc is fixed to the outer surface of the end, close to the gear, of the windshield wiper arm, cylinders with the same number as gear tooth grooves are annularly installed on the face, facing the gear, of the supporting disc at equal intervals, reset springs and movable rods are arranged inthe cylinders, and the ends, away from the reset springs, of the movable rods extend to the outer sides of the cylinders and are fixedly connected with push blocks matched with the gear tooth grooves; a movable magnet is installed on the side of the pushing block away from the gear center, and a fixed magnet which repels the movable magnet is installed on the position of the carrier plate facingthe meshing position of the gear and the gear rail. Compared with the prior art, the gear tooth groove cleaning device has the following beneficial effects that online cleaning of dust in a gear toothgroove is achieved, and accumulation of the dust in the gear tooth groove is prevented.

Description

technical field [0001] The invention relates to an automobile wiper, which belongs to the technical field of automobile accessories. Background technique [0002] Car wiper, also known as wiper, water dial, wiper or windshield wiper, is a device used to wipe off raindrops and dust attached to the windshield of the vehicle to improve the visibility of the driver and increase driving safety. [0003] The transmission mode in which rack bars and gears mesh is a common driving structure in automobile wipers, but during long-term use, dust is easy to accumulate in the tooth grooves of the gears. With the accumulation of dust, the rack bars and gears are not fully meshed. , not only affects the normal operation of the wiper, but also the components in the wiper are easily damaged due to uneven force, which affects the service life. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an automobile win...
