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 bidirectional rotating intelligent wiper motor automatic return gear, the gear 3 is installed in the end cover 2 of the motor body 1, and the gear 3 is embedded with a gear that rotates with the gear 3. The origin positioning magnet 4 and the inflection point positioning magnet 4-1, and the motion tracks of these two magnets are on two different circumferential lines in the same gear, and a circuit board 5 is fixed above the gear 3 And there is a gap between the gear 3 and the circuit board 5. The circuit board 5 is provided with an origin detection H...

Abstract

The invention relates to an automatic return gear for a motor of an intelligent electronic type contactless two-way rotary windscreen wiper. The gear is mounted at an end cover of the motor body; an origin positioning steel magnet and an inflection point positioning steel magnet which rotate with the gear are embedded on the gear and move along two different circumferences of the same gear. The automatic return gear is applied to the intelligent electronic type contactless two-way rotary 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. Moreover, no interference radiation is generated during the operation of the motor, and other electronic equipment in the vehicle can be protected from interference. Especially, a transmission assembly structure in a windscreen wiper assembly is eliminated. Therefore, due to the adoption of the automatic return gear, the windscreen wiper assembly is simpler in structure and lower in using cost. The automatic return gear fills the blank home and abroad in the field of motor industry of the automobile windscreen wipers.

Description

technical field [0001] The invention relates to an automobile wiper, in particular to an electronic non-contact bidirectional 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, heavy wear, short life, large deformation, complex process, high error rate and failure rate, poor quality stability, difficult installation, especially the side-to-side swing of the wiper needs to increase the transmission rod assembly, resulting in high cost and complex structure. . 2. The stop position control composed of three contact pieces and the stop copper plate has large deformation, short life, complicated bending process, h...
