Abstract

PURPOSE:To prevent water wiped by a wiper blade from flowing into a car room by making a side wiper into nonoperation at once unless it is not in operation at the time of opening detection of a side windowpane, lowering the wiper at once at the time of operation, and holding it in a storage position. CONSTITUTION:At the time of opening detection by a side windowpane opening detection means 2, operation of a side wiper is made into nonoperation at once unless it is in operation by a side wiper operating state detecting means 3, and if it is in operation, the wiper is lowered at once and held in a storage position. This control is carried out by transferring each of selector switches 9, 10 of a side wiper circuit 6 by a control circuit 1 and controlling feed to a wiper motor 11. When a side windowpane is opened, the side wiper operates so that water wiped by a side wiper blade is effectively prevented from flowing into a car room.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a side wiper device for a vehicle that wipes the outer surface of a side window glass.

(Prior Art) Conventionally, as shown in FIG. 5, a side wiper device d is known in which the outer surface of the glass C of a side window (side door) b is wiped by a wiper blade a that moves up and down (for example, tooG is a public notice). This side wiper device d has a side window glass C of a predetermined 1 fl L.
When the wiper blade a is closed by + or more, the wiper blade a moves up and down by turning on a side wiper switch (not shown).

Further, when the side window glass C is opened beyond a predetermined value Ll, the switch e is turned on, so that the wiper blade a does not move up or down even if the side wiper switch is turned on.

In this way, the opening degree of the side window glass C is set to the predetermined value L1.
Based on whether or not the wiper blade a
The reason for switching between the operating and non-operating states is that even in rainy weather, the vehicle may be driven with the side window glass C slightly open for ventilation or the like.

(Problem to be Solved by the Invention) However, in this case, while the wiper blade a is in operation, the side window glass C is opened to the position before the switch e is turned on (J), for example, as shown by the solid line in FIG. Furthermore, when the wiper blade J1 has reached the second limit position and the side window glass C is opened as shown by the two-dot chain line in the figure, a part of the wiper blade a is removed from the side window glass C. The wiper blade a comes off.
There is a possibility that water that has been wiped away may flow into the room. In addition, in order to prevent such water from entering the vehicle interior,
It is necessary to raise the opening detection position of the side window glass at which the side wiper is deactivated from, for example, 3 cm to Ir+n, and if this is done, the opening will become small and ventilation will not be performed well.

The present invention was made in view of the above circumstances, and the blade of the side wiper lowers the side window glass during operation.
An object of the present invention is to provide a side wiper device for a vehicle which, when the wiper blade is opened, prevents water wiped by the wiper blade from entering the interior of the vehicle while providing good ventilation.

(Means for solving the problem) Tree 1 to achieve the above purpose! The side wiper device of a JJ vehicle includes a detection means for detecting the opening operation of a side window glass, and a device that deactivates the wiper blade if the wiper blade is not in operation when a detection signal is output from the detection means. 1); If the wiper blade (I) is in operation, it is provided with a control means for controlling the wiper blade to be immediately lowered and held at the retracted position.

(Function) When an operation to open the side window glass is detected, if the wiper blade is not in operation, the wiper blade will not operate, and if the wiper blade is in operation, the wiper blade will immediately lower and stop at the retracted position. Since the water is retained, the water wiped away by the wiper blade does not flow into the room.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is an overall block diagram of a side wiper device for a vehicle according to the present invention, in which l is a control circuit (control means);
A side window opening operation detection means 2, a side wiper operating state detection means 3, a side window glass position detection means 4, and a side wiper switch 5 are electrically connected to the input side, and a side wiper drive circuit 6 is electrically connected to the output side. ing.

In the case of a vehicle equipped with a power window mechanism (not shown) that automatically opens and closes the side window glass (side door glass) 7 shown in FIG. , an ON signal for a switch (not shown) that opens the side window glass 7 only when it is pressed, or a full open switch (not shown) that opens the side window glass 7 to the fully open state when pressed once in the power window mechanism. ) detects the on signal. In addition, in the case of 111 cars that are not equipped with a power window mechanism, the side window glass opening operation detection means 2 continuously detects the opening degree of the side window glass 7 from fully closed to a predetermined value at which the side wiper is not activated. .

The rotation of the lever that opens and closes the side window glass 7 is detected. A detection signal output from the side window glass opening operation detection means 2 is input to the control circuit 1.

The side wiper operating state detection means 3 detects the operating state of a side wiper 8, which will be described later, and its detection signal is input to the control circuit 1.

The side window glass position detection means 4 detects the opening degree of the side window glass 7, and its detection signal is input to the control circuit 1.

The side wiper switch 5 is a self-returning switch that is turned on when pressed and turned off when released.When turned on, the side wiper 8 is operated, and its on/off signal is input manually to the control circuit 1.

The side wiper drive circuit 6 drives the side wiper 8 and includes first and second changeover switches 9 and 10, and a wiper motor 11. Double changeover switch 9, 10
The first terminals 9a and 10a are connected to the positive terminal 12 of the battery together with the control circuit 1. The second terminals 9b and ]Ob of both the changeover switches 9 and 10 are connected to ground via a resistor 13.

The third terminal 9c of the first changeover switch 9 is connected to the wiper motor 1.
1 is connected to one terminal 11a of 1.

The third terminal 10c of the second changeover switch 10 is connected to the other terminal 11b of the wiper motor 11.

The side wiper 8 has a wiper arm 8a as shown in FIG.
It has a wiper blade 8b attached to the tip of the wiper blade 8b. The base end of the wiper arm 8a is connected to the drive shaft of a wiper motor 11 via a power transmission means (not shown), and when the wiper motor 11 rotates forward and backward, the wiper blade 8b moves up and down within a predetermined range via the wiper arm 8a. The outer surface of the window glass 7 is wiped off.

When the side wiper 8 is not in operation, the wiper blade 8b is the second wiper blade 8b.
At this time, both control outputs (+) and (2) of the control circuit 1 are at a low level, and as shown in FIG. The terminal 9c is connected to the second terminal 9, and the third terminal 10c of the second changeover switch 10 is connected to the second terminal Job. In this state, no current is supplied to the wiper motor 11, so the side wiper 8 does not operate and is held stopped at the retracted position. From this state, when the first control output (1) of the control circuit l becomes a high (If i ) level, the first terminal 9a of the first changeover switch 9 changes to the first terminal 9.
a, the current from the positive terminal 12 of the battery is supplied to the single power terminal 11a of the wiper motor II via the first and third terminals 9a and 9C of the first changeover switch 9. This allows the wiper motor 11 to move in one direction (
(forward direction), and the wiper blade 8b moves upward.

When the wiper blade 8b passes the lower operating limit position shown in FIG. 2 13 and reaches the lower operating limit position shown in FIG. is input. Then, the control circuit l sets the first control output (1) to a low level and also sets the second control output (1) to a low level.
control output (2) is set to high level. As a result, the third terminal 9C of the first changeover switch 9 becomes the second terminal 9b,
The third terminal IOC of the second changeover switch IO is the first terminal 1
0a, and the current from the positive terminal 12 of the battery is supplied to the external power terminal 11b of the wiper motor 11 via the first and third terminals 10a and loc of the second changeover switch 10. As a result, wiper motor 1
1 rotates in the other direction (in the opposite direction), and the wiper blade 8
b goes down. When the wiper blade 8b reaches the lower operating limit position i3, the side wiper operating state detection means 3 detects this and the detection signal is input to the control circuit l. Then, the control circuit 1 makes the first control output (1) a high level and makes the second control output (2) a low level. As a result, current is supplied to one terminal 11a of the wiper motor 1■, so that the wiper motor 1
1 rotates in one direction again, and the wiper blade 8b rises again. Then, when the wiper blade 8b reaches the operating upper limit position C again, the wiper motor 1
The direction of rotation of the wiper blade 8b is changed, and the wiper blade 8b descends again, passes the lower operating limit position B, and reaches the first retracted position.

Then, the side wiper operating state detection means 3 detects this, and the detection signal is input to the control circuit 1. Thereby, the control circuit l outputs the first and second control outputs (1),
(2) are both set to low level, the current supply to the wiper motor 11 is cut off in the same manner as described above, and the wiper blade 8b is stopped and held at the retracted position. In this way, the wiper blade 8b rises from the storage position A, repeats the vertical movement twice between the operation lower limit position B and the operation upper limit position C, and then returns to the storage position Δ again and stops, which is one cycle. It has become.

Next, the operation of the vehicle side wiper device of the present invention is controlled by the third
This will be explained based on the diagram. FIG. 3 is a flowchart showing the control procedure of the control circuit I of the side wiper device of the present invention.

Since there is a risk that the side wiper 8 may come off, step 11 is executed to deactivate the side wiper 8.

If the answer to step 5 is negative (No), that is, if the opening operation of the side window glass 7 is not detected, this control operation is ended. Further, if the answer to step 5 is affirmative (Yes), that is, when the opening operation of the side window glass 7 is detected, it is determined whether or not the side wiper 8 is in operation based on the detection signal output from the side wiper operation state detection means 3. Determine (step 6).

If the answer is negative (NO), the side wiper 8 is deactivated (step 7), the flag F is set to O in the next step 8, and this control operation is ended. Also, Ste.
If the answer to the knob 6 is affirmative (Yes), that is, the side wiper 8 is in operation, it is determined whether or not the side wiper 8 is rising (step 13). The answer is affirmative (Yes),
That is, if the side wiper 8 is rising, the side wiper 8
A signal is output to reverse the rotational direction of the wiper motor 11, and the wiper blade 8b is reversed and lowered (step 14). Further, if the answer to step 13 is negative (NO), that is, if the side wiper 8 is descending, a signal is output to lower the wiper blade 8b to the retracted position while the rotational direction of the wiper motor 11 remains unchanged (step +
