Retractable windscreen wiper and operating method thereof

Abstract

The invention discloses a retractable windscreen wiper and an operating method thereof. One end of a main support plate is fixedly provided with a power device, the output shaft of the power device isprovided with a first connecting plate, and one end of the first connecting plate is hinged to a first connecting rod through a first hinge pin; a second connecting rod is hinged to the first connecting rod through a second hinge pin, one end of the first connecting rod is hinged to a first lug of a rotating plate; the tail end of the first connecting rod is hinged to a third connecting rod, andone end of the third connecting rod is hinged to a second lug of the rotating plate; the center of the rotating plate is fixedly provided with a rotating shaft, the top of the rotating shaft is fixedly connected with a rotary top plate which is matched with a retraction power mechanism, the retraction power mechanism is used for connecting with a crank-connecting rod mechanism which is used for extending and retracting, and the tail end of the crank-connecting rod mechanism is provided with a windscreen wiper rack. The retractable windscreen wiper can move circularly and meanwhile retractablyalong a guide sleeve to further change the working radius.

Description

technical field [0001] The invention belongs to the field of auto parts, and in particular relates to an auto wiper with telescopic function and an operation method. Background technique [0002] At present, the commonly used car wipers adopt a fixed-length structure, and the radius of rotation is fixed during the working process of the wiper, so that the cleaning range is limited. For some special cleaning requirements of car glass, it cannot meet the cleaning requirements. Therefore, it is necessary to A retractable car wiper with side length is designed for cleaning car glass. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a car wiper with a telescopic function. The wiper can also perform a telescopic movement along the guide sleeve while doing a circular motion, thereby changing the working radius of the wiper and making it suitable for special applications. car glass. [0004] In order to achieve the abov...
