Description
Technical field
The utility model relates to the express locomotive Windshield with scraping dust collect unit by water, by rainwater and other shelters on its removing Windshield, to obtain the visual field clearly, guarantees traffic safety when needed.
Background technology
At present; the electronic windshield wiper that uses on the locomotive has mainly adopted brush DC machine (being direct current permanent magnet motor) to drive; direct current permanent magnet motor is owing to the abrasion of brush, the reasons such as instability of load; using the later stage faults such as carbon brush rapid wear, motor ground connection often to occur; conventional motors overload protection deficiency is transshipped easily when windshield wiper wiper arm (sheet) high-drag is turned round and is damaged in addition, thereby directly influences the reliability of windshield wiper work; cause part replacement frequent, increase maintenance load.
Summary of the invention
The purpose of this utility model will provide a kind of express locomotive Windshield with scraping dust collect unit by water exactly, and it should be able to overcome the deficiencies in the prior art part preferably.
The technical solution of the utility model is as follows---and the express locomotive Windshield is with scraping dust collect unit by water, it contains a cover water storage spraying mechanism, control capsule, operating switch and two cover windshield wiper mechanisms, it is characterized in that: described water storage spraying mechanism comprises a bucket and a spray electric pump, water tank volume sprays 4 meters of electric pump lifts more than or equal to 15 liters; There are four winding terminals its side of described control capsule, and four set of connections terminals drive DC machine with 110 volts of direct supplys, operating switch, brushless wiper respectively and are connected with spray electric pump drive motor; Described operating switch contains the fourth gear rotor switch and the spray inching button of wiper control, fourth gear rotor switch wherein is used to handle brushless wiper and drives DC machine in reset switching between four kinds of states of high speed, low speed, discontinuous running and shutdown, and spray inching button side is used for control and sprays the electric pump drive motor; Every cover windshield wiper mechanism comprises that a brushless wiper drives the transmission device that DC machine, a cover contain worm and worm wheel, also have pedestal, main scraping arm, scraping arm connecting rod, pair to draw together arm and scraping blade, pedestal wherein, main scraping arm, scraping arm connecting rod, pair are drawn together arm and are constituted parallel-crank mechanism; Described brushless wiper drives DC machine and adopts the electronics mode to commutate, three Hall element Hall A, Hall B and Hall C are arranged at brushless wiper to be driven around the rotate path of DC motor rotor, when the magnetic pole that rotor is arranged skims over, Hall element all can be exported cooresponding high or low level according to the polarity of rotor magnetic pole, as long as the sequential that produces level according to three Hall elements is with regard to the decidable position of rotor at that time, and stator winding switched on accordingly; The DC machine that drives described brushless wiper adopts the PWM pulse modulation technology to carry out speed governing, use decuples the PWM drive waveforms of motor highest frequency, when the change in duty cycle of PWM drive waveforms, can cause that the available voltage on the motor stator changes, thereby realize that brushless wiper drives the speed governing of DC machine.
The beneficial effects of the utility model are: brushless wiper drives the life-span significant prolongation of DC machine, and package unit is reasonable in design, the reliability height, and electromagnetic compatibility is good.
Description of drawings
Fig. 1 is that brushless wiper drives DC machine driving principle figure.
Fig. 2 is the structural representation of windshield wiper mechanism.
Among the figure: 1 one brushless wipers drive DC machine, 1 ' one bearing, and 2 one worm screws, 3 one worm gears, 4 one pedestals, 5 one cranks, the 6-connecting rod, the 7-rocking bar, 7 '-main scraping arm, 8-scraping arm connecting rod, 8 '-scraping blade, the secondary scraping arm of 9-.
The specific embodiment
With reference to Fig. 1, microcontroller PIC18XX31 detects the current location that brushless wiper drives DC motor rotor according to Hall element Hall A, Hall B, Hall C, decide the order of opening or closing power transistor, make flow through in regular turn brushless wiper of electric current drive the stator winding of DC machine, to produce forward or reverse rotating field, and with the magnet mutual action of rotor, motor up time or inverse time are rotated.When rotor turn to Hall element detect another the group signal position the time, open next group power transistor again, so circulation, motor just can be rotated further according to same direction, when the controller decision stops rotor, then close power transistor; When the controller decision makes rotor reverse, then open power transistor, but reversed in order.We adopt the PWM pulse modulation technology to regulate the rotating speed that brushless wiper drives DC machine, use 10 times to the PWM of motor highest frequency drive waveforms, require PWM drive waveforms dutycycle is designed to 0.7 according to actual speed governing, the effective value of voltage is 77V on the corresponding stator at this moment, makes motor be issued at load-carrying ideal situation and requires rotating speed.
Fig. 2 is the structural representation of windshield wiper mechanism.This windshield wiper mechanism contain brushless wiper drive DC machine 1, bearing 1 ', worm screw 2, worm gear 3, pedestal 4, crank 5, connecting rod 6, rocking bar 7, main scraping arm 7 ', scraping arm connecting rod 8, scraping blade 8 ' and secondary scraping arm 9.Wherein, brushless wiper life-span of driving DC machine 1 only depend on bearing 1 ' life-span; Worm gear 3 adopts the non-metallic material integral die-cast, both has been convenient to technology controlling and process, also avoids simultaneously having improved reliability owing to produce the faults such as ground connection that metal powder causes; The four bar linkages that are made of pedestal 4, crank 5, connecting rod 6 and rocking bar 7 adopt the swivel coupling oscillating bearing, are convenient to guarantee the alerting ability of mechanism like this.
Test shows, the utility model can satisfy application requirements and parameter request fully, and is reasonable in design, has advantages such as reliability height, electromagnetic compatibility be good, is worthy to be popularized.
