Embodiment Construction

[0010] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0011] The present invention is an embodiment of an electronic non-contact one-way rotating intelligent wiper motor automatic return gear, the gear 3 is installed on the end cover 2 of the motor body 1, and the gear 3 is embedded with a A circular magnetic steel 4, a circuit board 5 is fixed above the gear 3 and there is a gap between the gear 3 and the circuit board 5, and a Hall switch 6 is arranged on the circuit board 5. The Hall switch 6 is installed on the opposite side of the circuit board 5 and the circular magnetic steel 4 circumferential line on the gear 3. When the gear 3 rotates with the motor, it passes directly...

Abstract

The invention relates to an automatic return gear for a motor of an intelligent electronic type contactless one-way rotary windscreen wiper. The gear is mounted at an end cover of a motor body; a round steel magnet rotating with the gear is embedded on the gear; a Hall switch is arranged on a circuit board; when the gear rotates with the motor and passes through the part below the Hall switch in every turn, the Hall switch acts; when the rotund steel magnet is away from the Hall switch, the Hall switch recovers, so as to detect the spindle origin position. The automatic return gear can be applied to the motor of the windscreen wiper and overcomes the long-existing defects that a mechanical contact type motor is cumbersome in structure, short in service life, high in failure rate, unstable in quality, difficulty in mounting.

Description

technical field [0001] The invention relates to an automobile wiper, in particular to an electronic non-contact one-way rotating intelligent wiper motor automatic return gear. Background technique [0002] At present, the wipers used in international and domestic automobiles are all mechanical contacts to form a wiper motor and electrical control structure. The disadvantages are: 1. The conversion switch composed of three gears in the first part has a large volume and weight, a large input current, and long-term operation. Repeated use has many disadvantages, such as heavy wear, short life, large deformation, complex process, high error rate and failure rate, poor quality stability, and difficult installation. 2. The stop position control composed of three contact pieces and the stop copper plate has large deformation, short life, complicated bending process, high failure rate and poor quality due to the long-term rotating contact between the three contact pieces and the sto...
