Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a self-adjusting wiper drive arm. 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 and worm mechanism. The rotating wheel is eccentrically connected with a drive arm. The drive arm drives a wiper arm through a connecting rod. The wiper arm is provided with a wiper. That is, after the wiper motor works, it drives the wiper to reciprocate. However, after a snowy night in winter, the wiper is easy to stick to the windshield, and once the driver activates the wiper, it is easy to damage the linkage parts or the wiper motor. SUMMARY OF THE INVENTION [0003] An object of the present invention is to provide a self-adjusting wiper drive arm, which has the feature of reducing the probability of damage to the wiper motor. [0004] The technical soluti...
