Abstract

The invention discloses a self-adjusting wiper driving arm. The self-adjusting wiper driving arm comprises a left plate body, a right plate body, a blocking column, a displacement sensor and an electric heating wire, wherein the right side of the left plate body is provided with an insertion column which extends to the right and has a rectangular cross section; the insertion column is provided with a hollow cavity; an inner coil is disposed in the hollow cavity; a side surface of the insertion column is provided with a blind hole; the left side of the right plate body is provided with a jack having a rectangular cross section; a side wall of the jack is provided with an outer hole; the outer part of the right plate body is provided with an outer coil; the blocking column is made of iron; the left plate body and the right plate body are made of plastics; reinforcing ribs made of magnesium-aluminum alloys are disposed inside the left plate body and the right plate body; two ends of the inner coil are electrically connected to two ends of the electric heating wire; the insertion column is inserted into the jack through clearance fit; the outer coil is connected to a power supply through a controller; the displacement sensor signal is connected to the controller; the blind hole and the outer hole are matched; the blocking column is located in the outer hole; one end of the blockingcolumn is matched with the blind hole. The self-adjusting wiper driving arm has the advantage that the probability of damage of the wiper motor can be reduced.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a driving arm of a self-adjusting wiper. Background technique [0002] The wiper is one of the important parts on the car. A common wiper includes a wiper motor. The wiper motor drives a rotating wheel through a worm gear mechanism. A driving arm is eccentrically connected to the rotating wheel. The driving arm drives a wiper arm through a connecting rod, and a wiper is arranged on the wiper arm. That is, after the wiper motor works, it drives the wiper to reciprocate. However, after the winter snowy night, the wiper is easy to adhere to the windshield, and once the driver starts the wiper, it is easy to damage the interlocking parts or the wiper motor. Contents of the invention [0003] It is an object of the present invention to provide a self-adjusting wiper drive arm with features that reduce the chance of damage to the wiper motor. [0004] The technical solution ado...
