Abstract

The invention relates to a car windscreen wiper protective device. The car windscreen wiper protective device comprises a windscreen wiper body and a driving assembly, the driving assembly comprises aswinging connecting rod, a driving motor, a reducer and a rotary shaft, one end of the swinging connecting rod is hinged to the windscreen wiper body, and a groove allowing the rotary shaft to be embedded in is formed in the other end of the swinging connecting rod; a clamping ball is further installed at the end, embedded in the swinging connecting rod, of the rotary shaft, the clamping ball isinstalled on the rotary shaft through a reset spring, an installation groove allowing the reset spring and the clamping ball to be jointly installed is formed in the rotary shaft, the outer side of the clamping ball extends out of the installation groove, and an arc-shaped groove attached to the clamping ball is further formed in the inner wall of the groove of the swinging connecting rod. The carwindscreen wiper protective device has the advantages that when the windscreen wiper body is stuck, as the torque of the driving motor increases, the clamping ball can be detached from the interior of the arc-shaped groove, in this way, the rotary shaft still rotates, but the windscreen wiper body does not rotate, and thus the phenomenon of rotating blocking of the driving motor caused by the stuck windscreen wiper body is avoided.
