Description

Car Washer Liquid Injector

The present invention relates to a washer fluid injector for automobiles, and in particular, the wiping operation of the wiper blade and the driving time difference of the washer fluid pump for injecting the washer fluid are prevented so that the liquid to which the washer fluid is injected does not impinge on the blade of the wiper. The invention relates to a washer fluid injector for cleaning a car.

In general, windshield glass of automobiles is equipped with wipers to secure the driver's field of view. This wiper allows the driver's watch to be secured by wiping the windshield glass with the vehicle's battery power to remove moisture and foreign matter present in the windshield glass. It is designed to work.

The washer refers to a device for spraying the cleaning liquid to the window, and sends the cleaning liquid stored in the tank located inside the vehicle hood to the pump to spray the nozzle toward the window. In addition to the type of diffusion nozzles having a large number of injection points or a fan-shaped divergence in order to distribute the liquid evenly over the entire glass surface, there are various types of nozzles, such as installing nozzles on arms or blades.

1 is a perspective view showing a conventional vehicle wiper arm portion and the mounting portion and the washer fluid injection device is provided with a washer fluid tank 100 containing a washer liquid in the hood and a washer fluid passing through the washer liquid tank 100 at the top of the hood. The 200 is connected to the front window nozzle 300 through which the washer fluid is injected by the action of the pump, and the front window nozzle 300 is provided on both sides of the lower part of the wiper.

As shown in FIG. 2, when the window wiper assembly W is mounted on a vehicle, a portion of the location unit 3 of the arm to which the blade is coupled is connected to the rotating shaft and the bolt of the motor mounted inside the vehicle through the mounting hole. Will be combined. Some vehicles are equipped with a wiper arm cover to prevent corrosion of the mounting part and to prevent foreign matter from penetrating the rotating part and improve the appearance. The support of the arm cover for this purpose is the wiper arm (1) and the location unit (3). It is made by pressing the fastening part of the cover to the hinge pin to couple the has a form covering the entire location unit.

The operation of this wiper is a first contact or second contact with a wiper drive switch (not shown) having an off contact, a first contact, and a second contact to spray washer fluid to remove moisture or foreign matter present in the windshield glass. When converted to, the wiper is driven to wipe off any moisture or foreign matter present in the windshield glass.

However, when the wiper is driven in this way, when the washer fluid is sprayed when the wiper is driven, the amount of washer fluid that is injected into the windshield class by hitting the wiper blade or the wiper assembly (W) is small, and thus it is impossible to evenly wipe the glass surface with the cleaning liquid. You have a problem.

Accordingly, the present invention has been made in view of the above problems, the object of the wiper blade is to drive the washer fluid pump for driving the wiping operation and the washer fluid to press the drive switch installed in the lower portion of the wind shield by the wiper operation Thus, when the wiper is located at the lower portion of the wind shield, the washer liquid is sprayed to provide a washer liquid injector to clean the entire surface of the class.

The present invention relates to a first drive switch having a switch contact point so that the washer fluid in the washer fluid tank is sprayed to the outside by a battery power source, a first relay having an interlocking contact point, and driven by an output of the first drive switch; A second drive switch for turning the contact on / off by wiping operation of the wiper, driven by the output of the second drive switch, a second relay having an interlocking contact, and driven by an interlocking contact of the second relay, The washer fluid can be achieved by a washer fluid injector consisting of washer liquid driving means having a predetermined time value such that the washer liquid is injected into the windshield glass through the injection nozzle.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a circuit diagram showing the configuration of the washer fluid injection device for a vehicle according to the present invention, the present invention according to the present invention by applying the battery power to wipe the water or foreign matter of the wind shield glass washer liquid to the wind shield glass through the injection nozzle A washer liquid injector, comprising: a first drive switch (10) for controlling a battery power to apply a battery power to a driver to wipe off water or foreign matter in a windshield glass of a vehicle; The first drive switch 10 is connected to the first relay 20, and the first interlocking contact 21 of the first relay 20 is connected in parallel with the first drive switch 10.

In addition, the second drive switch 30 is installed so that the switch contact is turned on / off by the wiper arm in the lower portion of the wind shield by the wiping operation of the wiper (W); The second drive switch 30 is connected to the second relay 40 by the second interlocking contact 22 of the first relay 20, and the first interlocking contact 41 of the second relay 40. Is connected in parallel with the second drive switch (30). The second interlocking contact 42 of the second relay 40 is connected to the washer liquid driving means 50.

The washer liquid driving means 50 is a timer 52 having a washer liquid pump 51 and a first time interlocking contact 52 'such that the battery power is controlled by a predetermined time value so that the washer liquid is injected to the outside.

Referring to the operation state of the present invention having such a configuration in more detail based on the accompanying drawings as follows.

As shown in FIG. 4, after the driver wipes the wiper to wipe off water or foreign matter from the windshield glass of the vehicle, the first relay 20 is driven when the first driving switch 10 is pressed. The first contact point 21 and the second contact point 22 of the first relay 20 are driven.

In addition, the first contact 21 and the second contact 22 of the first relay 20 are converted from the active contact to the break contact.

When the wiper presses the second drive switch 30 installed below the windshield by the wiping operation of the wiper, the second relay 40 is driven at this time, and the first contact 41 of the second relay 40 is performed. And the second contact 42 is driven. In addition, the first contact 41 and the second contact 42 of the second relay 40 are converted from the active contact to the brake contact.

The timer 52 of the washer liquid driving means 50 is driven by the second contact 42 of the second relay 40, and the washer liquid driving pump 51 is operated to inject the washer liquid into the windshield glass. The wiping action of the wiper wipes off the moisture and foreign matter on the windshield glass.

When the predetermined time value of the timer 52 elapses, the first interlocking contact 52 ′ of the timer 52 switches from the brake state to the active state, cuts off the battery power source, and then switches to the brake contact point again. At this time, when the driver presses the first drive switch 10, the washer liquid is injected into the glass by the wiping operation of the wiper. That is, the washer is sprayed by the wiping operation of the wiper so that it does not hit the blade of the wiper.

Therefore, when the driver presses the first drive switch 10 to wipe off the water or foreign matter on the windshield glass, the wiper arm of the wiper is moved to the second drive switch 30 installed under the windshield by wiping operation of the wiper. In this case, the washer liquid pump is driven, and the washer liquid is injected into the glass, and the blade of the wiper wipes the glass.

As described above, the washer fluid injector according to the present invention, when the second drive switch installed in the lower portion of the wind shield is pressed by the wiping operation of the windshield glass, the washer fluid is injected, so washer fluid In the process of spraying, the amount of spraying on the glass is reduced while hitting the blade, while at the same time the amount of spraying on the glass is kept constant and has the advantage of being able to wipe clean with a predetermined amount.
