Abstract

The invention discloses a driving device of a wiper blade, a wiper system and an automobile. The driving device of the wiper blade comprises a mounting rack, a driving mechanism, a rotating crank rod, a connecting rod and a first rocker, wherein the mounting rack is mounted on a front window of the automobile, the driving mechanism is mounted on the mounting rack and is provided with a rotating part, one end of the rotating crank rod is in driving connection with the rotating part, one end of the connecting rod is rotatably mounted at the other end of the rotating crank rod, a mounting part is formed at the other end of the connecting rod, the first rocker is provided with a mounting end, the mounting end is rotatably mounted on the mounting frame for mounting the wiper blade, the mounting part is rotatably mounted on the first rocker and can move in the length direction of the rocker to change the distance between the mounting end and the mounting part, and the angular acceleration of the mounting end of the first rocker at the limit position is reduced, so that the angular velocity of the wiper blade connected with the mounting end at the upper and lower limit positions of the wiping area is reduced, the angular momentum of the wiper blade at the upper and lower limit positions is reduced, and the problem of edge hitting during high-speed operation of the wiper blade can be avoided.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a driving device for a wiper blade, a wiper system and an automobile. Background technique [0002] In rainy and foggy weather, the driver needs to drive the wiper blades to reciprocate to wipe the front windshield, but the driving mechanism for driving the wiper blades usually uses a four-bar linkage to form a quick return reciprocating motion, which is finally expressed as the wiper blades on the wiper arm. The wiper movement of the front windshield will cause the angular velocity of the wiper blade in the reversing area to be too high during the wiper cleaning, and because the greater the angular velocity, the greater the angular momentum generated, so it is easy to cause the wiper blade to collide The phenomenon of the A-pillar sheet metal and the wiper cover, that is, the edge of the wiper, seriously affects the service life of the wiper. Contents of the invention [0003] The ...
