Abstract
An automatic window wiper motor is composed of a speed reducer assembly, a rotor assembly, a stator assembly, an infrared rainwater detecting device, and an electronic element plate component for controlling the rotational speed of the motor is arranged in the speed reducer assembly. By adopting the technical structure provided by the utility model, the rainwater wiping frequency is set in advance, the speed of a rainwater wiping arm is automatically controlled according to the amount of rainwater, and the rainwater wiping effect is good.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of automatic windshield wiper motor.
Background technology
The windshield wiper motor of prior art all is to be made up of parts such as reducer shell assembly, brush holder yoke assembly, rotor assembly, stator module, driving gear, gear cover plate assemblies; Wherein the reducer shell assembly comprises that decelerator shell, gear shaft, rotor assembly comprise motor shaft, rotor, commutator; Driving gear is meshed with motor shaft and is connected; Driving gear is fixed on again on the gear shaft, and gear shaft then links to each other with the outer transmission part of motor.Its course of work is: the rotation through motor shaft drives driving gear and makes the gear shaft rotation, thereby drives transmission part work.For the motor of windshield wiper (being wiper) usefulness; Its weak point is: though windshield wiper is provided with the rotating speed of the hand control switches of many retainings with the control electrical motor for scraping rain according to the size of rainfall, can not regulate the size that the windshield wiper rotating speed of motor adapts to rainfall automatically in fact.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and provide a kind of can be when different rainfall to scrape the automatic windshield wiper motor that speed is come work accordingly.
The automatic windshield wiper motor that the utility model provided is realized through following technical scheme: a kind of automatic windshield wiper motor; Form by decelerator assembly, rotor assembly, stator module, infrared ray rainwater sniffer; Electronic component board component with control motor speed also is housed in described decelerator assembly; On this electronic component board component single chip circuit is housed, with the pre-set program that can control the electrical motor for scraping rain rotating speed according to the size of rainfall, the electronic component plate is connected with electric electromechanics in the circuit; Also be connected with plug connector on the electronic component board component, connector is connected with infrared sensor.
After adopting the technical pattern that the utility model provided; Windshield wiper can open or close according to whether raining to decide; And can be according to the size of rainfall and control automatically wiper arm scrape speed, scraping the water frequency, to preestablish, scrape water effective, easy to install, simple in structure, is specially adapted to automobile wiper device assembly.
Description of drawings
Below in conjunction with accompanying drawing and execution mode the utility model is done further to describe in detail.
Fig. 1 is the structural representation of the automatic windshield wiper motor of the utility model.
Fig. 2 is the structural representation of decelerator assembly of the automatic windshield wiper motor of the utility model.
Fig. 3 is the structural representation of circuit board assemblies of the automatic windshield wiper motor of the utility model.
Fig. 4 is the structured flowchart of infrared ray rain sensor assembly of the automatic windshield wiper motor of the utility model.
Embodiment
Can know referring to figs. 1 through Fig. 3; The automatic windshield wiper motor of the utility model comprises that decelerator assembly 12, stator module, rotor assembly, brush holder yoke assembly, electronic component board component 22, wherein said decelerator assembly 12 comprise decelerator shell 14, deceleration worm screw 7, deceleration worm gear 15, worm-wheel shaft 20, curved arm rod and sector gear 17, rotary teeth wheel shaft 18, swiveling gear arm, swiveling gear 16, power output shaft 21, and electronic component board component 22 is installed in the another side of reducing gearbox; Stator module comprises the oiliness bearing 11 of magnetic steel of stator 2, motor housing 1 and top installation; Rotor assembly comprises motor shaft 8, rotor core 9, rotor winding 5, commutator 10, and the brush holder yoke assembly comprises brush carrier 4, carbon brush 3, the wherein corresponding installation in commutator 10 positions of carbon brush 3 and the rotor assembly of brush holder yoke assembly, and the magnet steel 2 of stator module is installed on the inwall of motor housing 1; Oiliness bearing 11 is installed in the bottom of motor housing 1; It is supporting the running of the motor shaft 8 in the rotor assembly, is coaxially installed with rotor core 9 above the motor shaft 8, on rotor core, is wound with rotor winding 5; Commutator 10 also is installed in above the motor shaft 8; The moment that the rotor rotation produces through being installed in the deceleration worm screw 7 on the motor shaft 8, is delivered to above the deceleration worm gear 15; Worm-wheel shaft 20 is being supported the rotation of worm gear 15; With worm-wheel shaft 20 coaxial mounted curved arm rods and sector gear 17, the power that worm gear 15 is transmitted passes to pass to rotation again and changes gear 16, is supporting rotation to change the power output shaft 21 of gear 16 rotations; rotation is changeed the torque that gear 16 accepts pass to the windscreen wiper arm again, transmission of power is given the windscreen wiper sheet the most at last.
Accompanying drawing 4 is infrared ray rainwater sniffers; This device is installed in the front windshield back; Send IR, thereby, then signal is passed to the single chip circuit 22A that is installed in above the electronic component plate 22 according to the rainy situation that the refraction situation of IR in windshield detects.
The course of work of the utility model is such; When raining; The infrared ray rainwater sniffer that front windshield is installed at the back; Send IR and decide windshield wiper whether to open according to the refraction situation of IR in windshield, and start corresponding program according to the size of rainfall, the windshield wiper motor begins rotation automatically; Scraping arm is started working; Program that solidify among the single chip circuit 22A on circuit board assemblies 22, that finish writing in advance, that can control windshield wiper motor rotation is sent instruction, makes the windshield wiper motor at a high speed or low speed or by the work of corresponding interval with stop, thereby drives transmission part (can be the windscreen wiper arm) at a high speed or low speed or by the work of corresponding interval with stop.
After adopting the technical pattern that the utility model provided, control scraping speed, scraping that the water frequency preestablishes, to scrape water effective of wiper arm automatically according to the size of rainfall.
