A device for cleaning the glass of the vehicle
(57) Abstract:The invention relates to electric vehicles, and in particular to systems for cleaning and washing the windscreen or glass headlights. The purpose of the invention is improving the efficiency of cleaning the glass and save the scrubbing liquid. The device comprises a washer with electric drive 3, delivery system washer fluid in the washer with pipelines, the wiper brush 13 and the drive motor 1. The wiper motor 1 is connected through a worm 1 and gear 3 with a limit switch 4. Limit switch 4 is made in the form of a disk, one half of which is covered with a conductive 5, and the other tokoprovodyaschym layer 6, and two contact plates 7 and 8. Due to the presence of the electromagnetic valve 10 associated with limit switches 4, synchronized with the movement of the brush 13 wiper, washing fluid is supplied to the glass, when the engine 9 washer, and always before moving the brush 13, which increases the cleaning efficiency and saves washing up liquid. 2 C.p. f-crystals, 2 Il. The invention relates to electric vehicles, and in particular to systems for cleaning and washing the windshield is tion , which contains the wiper motor, the shaft of which is made of worm thread, which is connected with the plastic gear, limit switch, consisting of contact of the disk with a slot mounted on the axis of the gear, and the contact plate, the washer motor and the switch included in the power supply circuit of the motor of the washer.The disadvantage of this device is a conflict of the moment of injection of the liquid on the glass and the position of the wiper blades, which occur when the liquid enters instead of glass on the brush, thereby reducing the cleaning efficiency. This forces the driver involuntarily to observe the position of the moving brush and turn the wiper motor when the brush does not block the path of the stream of liquid. The driver's attention is distracted, and consequently, reduced traffic safety.It is also known a device for cleaning the glass of the vehicle  was chosen for the prototype and containing a worm gear through which the shaft of the wiper motor is connected with the gear mounted on the axis of the first limit switch, made in the form of contact of the disk with a slot and pin limit switch, mounted coaxially to the first end switch, and is made in the form of the contact drive plate and the two contact plates, one of which is installed with the possibility of interaction with the contact disk and the other with its ledge, with the slot of the contact disc one switch and the protrusion of the contact disc of the other are in phase.The disadvantage of the prototype is the poor efficiency of cleaning of the glass due to the fact that the washing liquid can be fed to a glass or before moving the wiper blade, or after it. It depends on the random moment of turning on the washer relative to the position of the moving brushes. When the supply of washer fluid for cleaning brush glass is only possible when the brush reaches the end position and back in the reverse course. During this time, the washing liquid flows from the glass, in addition, and cleanup is delayed.The aim of the invention is to increase the efficiency of cleaning the glass and save the scrubbing liquid.This is achieved by a device for cleaning glass vehicles containing washer with electric drive, the delivery system washer fluid in the washer with TRU in the form of a worm and cooperating gear with limit switches, mounted coaxially with the gear and made in the form of a disk located on the side of the two contact plates, each of which is associated respectively with one of the poles of the motor of the washer, the limit switch is made in the form of a disk, one half of the lateral surface of which is covered with a conductive and the other tokoprovodyaschym layer, with the border between them and the contact plates are mounted in-phase bottom position of the wiper blade, and the supply system washer fluid to the washer is equipped with an electromagnetic valve electrically connected on one side to one of the contact plates, and on the other hand - with the wiper blade, moreover, the supply pipe washer fluid on the glass are located on both sides of the wiper blade. In addition, the supply pipe washer fluid on the glass made with holes on the sides of the glass and installed parallel to the longitudinal axis of the brush. When this solenoid valve is made in the form of a hollow body of non-magnetic material fixed therein by means of spring magnetic piston mounted with its outer surface on one side of the casing pipes for communicating the cavity housing the koi.In Fig. 1 presents a functional diagram of the device of Fig. 2 - solenoid valve.The device includes a wiper motor 1, the associated shaft with the worm gear in the form of a worm 2 and gears 3. On the axis of the gear 3 fixed limit switch 4, made in the form of the contact disk comprising two diametrically halves 5 and 6, one of them is covered with a conductive layer, and the other of the dielectric. The contacts of the limit switch 4 is made in the form of the contact plates 7 and 8 which are pressed to the surface of the contact disk and installed the in-phase with one another. The contact plate 7 is connected to one pole of the electric motor 9 of the washer and the plate 8 through the solenoid valve 10 to the other pole of the motor 9. The first 11 and second 12 pipelines feeding washing liquid fixed respectively with one and the other side of the brush 13 wiper and connected with the first 14 and second nozzles 15 of the valve 10. The pipes 12 and 11 are installed along and parallel to the brush 13 and is provided with holes 16 from the side of the glass (not shown) of the vehicle. The third pipe 17 of the valve 10 is connected to a pump (not shown) washer. Brush 13 through levers and crank IU the values 5 and 6 of limit switch 4 and the position of the plates 7 and 8. The solenoid valve 10 includes a non-magnetic body 18, over which is wound electrical winding 19, which is included in the circuit of the contact switch 4 and the electric motor 9. In the cavity 20 of the housing 18, is equipped with nozzles 14, 15 and 17, has a magnetic piston 21, provided with a return spring 22.The device operates as follows.In the initial state, the brush 13 wiper is in the lowest position, the contact plates 7 and 8 are located on the boundary surfaces 5 and 6 of switch 4. The valve 10 is de-energized and the magnetic piston 21 is in the left position (see Fig. 2).When turning on the wiper motor 1 starts to rotate, the movement through the worm 2 is transmitted to the gear 3 and the limit switch 4, and in addition, the brush 13. The brush 13 is coming up. If at this point to include a washer by Cycling power to the motor 9, the washer pump through the outlet 17 of the valve 10 supplies the washing liquid in the cavity 20 and through the pipe 14 into the pipe 11 located above the brush. Through holes 16 along the pipeline, the washing liquid is fed to the glass before moving brush. At this time, the plates 7 and 8 slide on a non-conductive surface 6 off protivopolojnuu the boundary surfaces 5 and 6 due to the rotation of the contact disc of the switch 4. The switch 4 closes and supplies power to the coil 19 of the valve 10. The magnetic piston 21, compressing the return spring 22, the magnetic field winding 19 is moved to the right (see Fig. 2) and overlaps the channel of the feed of washing liquid from the nozzle 17 to the pipe 14 and the pipe 11. Simultaneously, the piston 21 opens the feed of washing liquid from the nozzle 17 through the cavity 20 to the pipe 15, the pipe 16 located below the brush 13. Washing fluid through the openings 16 again before moving the brush 13 is injected on the glass throughout it. With the advent of the brush 13 to the lowest position, the valve 10 is de-energized due to the opening of the switch 4, the return spring 22 returns the piston 21 to its original state. The process is repeated. Pipes 11 and 12 with nozzles 14 and 15 are made of an elastic material. Thus, the invention improves the speed and quality of cleaning the glass, almost without distracting the driver's attention from other controls and road conditions. All these factors ultimately increase traffic safety.The invention can be used for cleaning as windshields and glass headlights. 1.
