Abstract
The utility model relates to an automatic returning gear for an electronic noncontact bidirectional rotational intelligent wiper motor. The automatic returning gear is installed in an end cover of a motor body. Original-point positioning magnetic steel and inflection-point positioning magnetic steel, which rotate along with the gear, are embedded on the gear. Motion curves of the two magnetic steels are on two different circumferences of the same gear. The automatic returning gear is applied to the electronic noncontact bidirectional rotational intelligent wiper motor so that the new motor is enabled to overcome disadvantages, which exist in mechanical-contact-type motors for a long time, of heavy structure, short service life, high failure rate, unstable quality and difficult installation and the like and no interference radiations are caused in an operation process of the motor so that other electronic devices in an automobile are protected from effects of the interferences and particularly, a transmission assembly structure is saved in a wiper assembly so that the wiper assembly is simpler in structure and lower in use cost. The automatic returning gear for the electronic noncontact bidirectional rotational intelligent wiper motor fills blanks in the field of automobile wiper motor industries at home and abroad.
Description
Technical field
The utility model relates to a kind of vehicle wiper, especially a kind of electronic non-contact bidirectional rotation screen wiper motor self-return gear.
Background technology
The wiper of using on international and domestic automobile is at present all that mechanical contact-type forms a wiper motor electrical equipment control structure, its shortcoming is: change type volume of switch weight that 1, first's third gear position forms is large, input current greatly, the use wearing and tearing that go round and begin again are for a long time large, the life-span is short, distortion is large, complex process error rate and failure rate is high, quality stability is poor, installation is difficult, particularly rain brush is vacillated now to the left, now to the right and need to be increased drive link assembly and could realize, cause the shortcomings such as cost macrostructure complexity.2, the off-position that three contact pieces and off-position copper coin form control due to the long-term contact wear distortion that is rotated formula with off-position copper coin of three contact pieces greatly, life-span is short, the complex process of bending, failure rate is high, quality is unstable, the shortcomings such as cost is large, and when moving, motor have the brush of three groups of speed-regulating functions with the electronic jamming width of motor gear operation friction generation, to penetrate other electronic equipments of automobile with the contact piece of high speed operation of motor friction and three groups of positioning functions, the wearing and tearing that particularly cause with the high-speed cruising of motor have reduced the useful life of motor and the raising of failure rate widely.
Utility model content
The technical problems to be solved in the utility model is: propose the problem that automobile wiper motor that a kind of electronic non-contact bidirectional rotation screen wiper motor thoroughly solves current mechanical contact-type structure brings.
The technical scheme that the utility model adopts is: a kind of electronic non-contact bidirectional rotation screen wiper motor self-return gear, this gear is arranged in the end cap of motor body, on described gear, be embedded with original point position magnet steel and the flex point positioning magnetic steel of with gear, rotating, and on two different circumferences of the movement locus of these two magnet steel in same gear, the top of described gear is fixed with between a circuit board and gear and circuit board and leaves gap, on described circuit board, be provided with an initial point corresponding with described original point position magnet steel and detect Hall switch and a flex point detection Hall switch corresponding with flex point positioning magnetic steel, these two Hall switch be installed in circuit board with on gear with corresponding magnet steel circumference separately on a relative side, when gear is during with electric machine rotation, original point position magnet steel will trigger origin switch action when initial point detects under Hall switch, prompting motor should commutate, flex point positioning magnetic steel will trigger flex point switch motion when flex point detects under Hall switch, prompting motor should commutate.
The beneficial effects of the utility model are: electronic non-contact bidirectional rotation screen wiper motor self-return gear of the present utility model is applied on electronic non-contact bidirectional rotation screen wiper motor, overcome the long-standing structure heaviness of mechanical contact-type motor for a long time, life-span is short, failure rate is high, quality is unstable, the shortcomings such as difficulty are installed, and motor does not have interference emission to produce in running, protected again the interference-free impact of other electronic equipments in car, particularly in wiper assembly, saved the structure of drive assembly, make wiper assembly structure simpler, use cost is lower.The utility model has been filled up international and domestic blank in automobile wiper motor industry field.
