DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a control device for a retractable rear window and a rear wiper for a vehicle.

(Prior Art) Conventionally, this type of control device has been applied to, for example, an openable rear window and a rear wiper of a sports wagon. By the way, in the case of such a control device, if the ignition switch of a sports wagon is turned off while the rear wiper is operating with the rear window fully closed, the wiper blade of the rear wiper is immediately turned off. Therefore, when the rear window is opened by operating the wind switch located on the outside of the rear of the Sports Wagon under such conditions, the wiper blade comes off the rear window that is opening and enters the inside of the Sports Wagon. There is a risk of inviting

(Object of the Invention) The present invention has been made to address the above-mentioned problems, and its object is to provide a control device for a vehicle opening/closing rear window and a rear wiper. To prohibit opening of a rear window when the wiper blade of the rear wiper is stopped at a position other than the retracted position due to a non-operation state during operation of the rear wiper with the rear window fully closed.

(Structure of the Invention) In achieving the above object, the structural features of the present invention include a drive mechanism that is put into an operating state necessary to open the retractable rear window of the vehicle, and a drive mechanism that wipes the rear window with a wiper blade. a fully closed detection means that is applied to a rear wiper that is placed in an operating state necessary for the operation, detects when the rear window is fully closed, and enters a fully closed detection state; a first signal generating means that is supplied with power from a DC power source in response to operation of an ignition switch of a vehicle and generates a drive signal necessary to put the rear wiper into operation; and when the wiper blade reaches a retracted position. It has a storage detection means that detects this and enters the storage detection state, and is operated when the rear wiper is placed in the operating state and applies a drive signal from the first signal generation means to the rear wiper, and the rear wiper is placed in the non-operation state. a first operating means for stopping application of the drive signal from the first signal generating means to the rear wiper in response to a change in the storing detecting state of the storing detecting means; a second operating means that is operated to generate an operating signal when opening the rear window when the rear window is not operated; and a second operating means that is supplied with power from the DC power source in response to the operating signal and is necessary for placing the drive mechanism in the operating state. and a second signal generating means for generating a drive signal and applying it to the drive mechanism, when the ignition switch is in the non-operated state when the storage detection means is not in the storage detection state, the operation is stopped. prohibition means for prohibiting power supply from the DC power supply to the second signal generation means regardless of the generation of a signal; and a prohibition means for prohibiting power supply from the DC power supply to the second signal generation means, and the fully closed detection means is not in the fully closed detection state, and the storage detection means is in the storage detection state. The present invention further includes an auxiliary operating means which is operated when the ignition switch is not in use and allows power to be supplied from the DC power supply to the first signal generating means under the operation of the ignition switch.

(Effects of the Invention) By configuring the present invention in this manner, the rear wiper is operated in its operating state under the operation of the first operating means under the operation of the ignition switch of the vehicle. When the ignition switch is set to a non-operating state while the rear wiper is being wiped by the wiper blade, and an operating signal is generated from the second operating means, the power supply from the DC power source is interrupted. Even if the rear wiper is deactivated in response to disappearance of the drive signal from the first signal generating means and the wiper blade that is in the wiping operation is immediately stopped, the second signal generating means is activated by the inhibiting means. Regardless of the generation of the operation signal, reception of power from the DC power supply is prohibited and no drive signal is generated, so that the rear window can be maintained in a fully closed state without opening. The occurrence of the above-mentioned problems can be prevented in advance and reliably. Therefore, the wiper blade will not be caught between the rear window and its window frame.

Also, for some reason, the wiper blade leaves its storage position and the rear window opens slightly from its fully closed state, causing the retraction detection means to be released from its retraction detection state and the wiper blade to open from its fully closed position. Even if the closed detection means is released from the fully closed detection state, if the auxiliary operation means is operated, the first signal generation means will not receive power from the DC power supply under the operation of the ignition switch. Since the drive signal is generated when the first operating means is operated, the wiper blade of the rear wiper is operated in response to the drive signal from the first signal generating means, and then the first operating means is operated. By setting the wiper blade to the non-operating state, the wiper blade can be stored in its retracted position and the retraction detection means can be brought into the retraction detection state, and based on this retraction detection state, the second operating means can determine the appropriateness of the rear window. This makes it possible to perform a wide opening operation. In other words, even if the retraction detection means is released from the storage detection state and the fully closed detection state is released for some reason, both the drive mechanism and the rear wiper cannot be operated by operating the auxiliary operation means. The condition can be easily released.

(Example) An embodiment of the present invention will be described below with reference to the drawings. The drawings show an example in which the control device according to the present invention is applied to a drive mechanism and a rear wiper for an openable rear window provided at the rear of a sports wagon. The rear wiper is configured to wipe the wiper blade by repeatedly sliding the wiper blade back and forth across the wipe area in the upper central half of the outer surface of the rear window by rotation of the rotary electric motor M1. has been done. On the other hand, the drive mechanism is configured to open (or close) the rear window by normal rotation (or reverse rotation) of the rotary electric motor M2.

The control device according to the present invention includes a wiper operating mechanism 1
0, relay 20, normally open type fully closed detection switch 30a
and an operating switch 30b, and the fully closed detection switch 30a detects when the rear window is fully closed and closes it to enter the fully closed detection state, and opens when the rear window is opened to detect the fully closed state. Cancels the closed detection state. The operation switch 30b is disposed at a suitable location in the cabin of the sports wagon, and is connected in parallel to the fully closed detection switch 30a. Thus, the operation switch 30b short-circuits the fully closed detection switch 30a by its closing operation.

The relay 20 has an electromagnetic coil 21 and a double-throw switch 22. The electromagnetic coil 21 is grounded at one end via a fully closed detection switch 30, and the other end is connected to the ground via the fully closed detection switch 30. It is connected to the positive terminal of DC power supply B via ignition switch IG. Therefore, under the fully closed detection state of the fully closed detection switch 30a, the ignition switch IG closes by inserting the ignition key of the sports wagon into the ignition cylinder located in the passenger compartment. Then, the electromagnetic coil 21 receives power from the DC power source B and is excited. Moreover, this electromagnetic coil 21 is cut off from the DC power supply B and becomes demagnetized by opening the fully closed detection switch 30 or the ignition switch IG. The double-throw switch 22 has both fixed contacts 22a and 22b, and each fin fixed contact 22a,
The fixed contact 22a is grounded, while the fixed contact 22b is connected to the positive terminal of the DC power supply B. Thus, the double-throw switch 22 closes the double-throw contact 22c to the fixed contact 22a when the electromagnetic coil 21 is demagnetized, and also closes the double-throw contact 22c to the fixed contact 22b in response to the excitation of the electromagnetic coil 21. Then, power is supplied from DC power supply B to both contacts 22c.

The wiper operating mechanism 10 includes a wiper switch 1
1, and a pair of normally closed storage detection switches 12 and 13
and an electromagnet 14, and the storage detection switch 12 detects when the wiper blade reaches the upper edge of the wiping area (i.e., the first storage position) and opens to enter the storage detection state. . The storage detection switch 13 is configured to detect when the wiper blade is in the first position.
When it is retracted from the retracted position to the second retracted position located above it by the plunger of the electromagnet 14 as will be described later, this is detected and opened to enter the retracted detection state. After the electromagnet 14 receives power supply excitation to its electromagnetic coil, the plunger is displaced by the electromagnetic force caused by the power supply excitation being cut off, and the wiper blade is stored from the first storage position to the second storage position. The movable contact of the storage detection switch 13 is grounded regardless of whether the wiper switch 11 is operated or not.

When the wiper switch 11 is operated, the double-throw contact 2 of the double-throw switch 22 in the relay 20 is
2c is connected to the non-grounded side input terminal of the electric machine winding of the rotary motor M1. This means that, in response to the operation of the wiper switch 11, the rotary electric motor M1 is supplied with power from the DC power source B via the double-throw contact 22c of the double-throw switch 22 and rotates. Further, when the wiper switch 11 changes from an operating state to a non-operating state, it connects the double-throw contact 22c of the double-throw switch 22 to the non-ground side input terminal of the electric machine winding in the rotary motor M1 via the storage detection switch 12. It is connected to one terminal of the electromagnetic coil of the electromagnet 14, and the other terminal of the electromagnetic coil of the electromagnet 14 is grounded together with the movable contact of the storage detection switch 13. In other words, in response to the change of the wiper switch 11 to the non-operating state, the rotary electric motor M1 is supplied with power from the DC power source B via the double-throw contact 22c of the double-throw switch 22 and the storage detection switch 12, and continues to rotate. In response to the change of the retraction detection switch 12 to the retraction detection state, the power supply is cut off and the electromagnet 14 stops, and in response to the change of the wiper switch 11 to the non-operating state, the electromagnet 14 is connected to the other end of its electromagnetic coil. It is grounded together with the movable contact of the storage detection switch 13, and at the same time, its electromagnetic coil receives power from the DC power supply B via the double-throw contact 22c of the double-throw switch 22 and the storage detection switch 12, and is excited. It is cut off in response to a change from excitation to the storage detection state of the storage detection switch 12.

There is. Further, the transistor 61 is grounded at its emitter, and the transistor 61 is grounded at its emitter.
The collector of No. 1 is connected to the positive terminal of DC power supply B via electromagnetic coil 81 of relay 80. Thus, the transistor 61 is supplied with power from the DC power supply B via both resistors 62 and 63 in response to the closing of the ignition switch IG, and becomes conductive, and is rendered non-conductive in response to the opening of the ignition switch IG. becomes.

The relay 80 has the above-mentioned electromagnetic coil 81 and a normally open switch 82.

They are connected to the opening side fixed contact 42 and the closing side fixed contact 43 of the window switch 40 through the terminals 0c, respectively. Thus, in response to the conduction (or non-conduction) of the transistor 61, the electromagnetic coil 81 receives power from the DC power supply B and is excited (or demagnetized).
Furthermore, when the transistor 61 is non-conductive, the electromagnetic coil 81 turns on the diode 50a in response to the opening fixed contact 42 or the closing fixed contact 43 of the double throw contact 41 of the window switch 40.
Alternatively, when 50c is turned on, it receives power from the DC power supply B and is excited, and is demagnetized by cutting off the power supply by returning the double-throw contact 41 to the neutral position. The normally open switch 82 is closed in response to the excitation of the electromagnetic coil 81, and opened in response to the demagnetization of the electromagnetic coil 81.

The transistor circuit 70 has a pair of transistors 71 and 72, and the base of the transistor 71 is grounded through a resistor 71a.
Further, the emitter of the transistor 71 is connected to the positive side terminal of the DC power supply B via the switch 82 of the relay 80, and the collector of the transistor 71 is connected to the positive side terminal of the window switch 40 via the electromagnetic coil 91 of the relay 90 and the diode 50b. It is connected to the opening side fixed contact 42 and the relay 100
It is connected to the closing side fixed contact 43 of the window switch 40 via the electromagnetic coil 101 and the diode 50d. Thus, transistor 71 responds to the closing of switch 82 of relay 80 and resistor 7
Power is supplied from the DC power source B through 1a, and conduction occurs, and when the switch 82 of the relay 80 is opened, the DC power source B
It is cut off from the current and becomes non-conductive.

The transistor 72 has its collector connected to the base of the transistor 71, and its emitter connected to the positive terminal of the DC power supply B via a switch 82 of a relay 80. Also,
The base of the transistor 72 is connected to a fixed contact of the storage detection switch 13 via a resistor 72a, and is also connected to the emitter of the transistor 72 via a resistor 72b. However, transistor 7
2, when the wiper switch 11 is not operated and the storage detection switch 13 is closed, both resistors 72a and 72 are turned on in response to the closing of the switch 82 of the relay 80.
Power is supplied from the DC power supply B via the DC power source B to maintain the conductive transistor 71 in a non-conductive state, and when the wiper switch 11 is operated, the storage detection switch 13 is in the storage detection state, or the switch 82 of the relay 80 is opened, the voltage is supplied from the DC power supply B. It is cut off and becomes non-conductive.

The relay 90 has an electromagnetic coil 91 connected as described above and a double-throw switch 92, and the electromagnetic coil 91 is supplied with power from the DC power supply B via the switch 82 of the relay 80 in response to the conduction of the transistor 71. It is energized and is demagnetized by being cut off from the power supply by the non-conduction of the transistor 71. The double-throw switch 92 has a double-throw contact 92a and both fixed contacts 92b, 92c, and the double-throw contact 92a is connected to the first input terminal of the armature winding of the rotary motor M2. The fixed contact 92b is grounded, while the fixed contact 92c is connected to the positive terminal of the DC power supply B via the switch 82 of the relay 80. Thus, the double-throw contact 92 connects the double-throw contact 92a to the fixed contact 9 when the electromagnetic coil 91 is demagnetized.
2b, and in response to the excitation of the electromagnetic coil 91, the double-throw contact 92a is turned on to the fixed contact 92c.

The relay 100 has an electromagnetic coil 101 connected as described above and a double-throw switch 102, and the electromagnetic coil 101 is supplied with power from the DC power supply B via the switch 82 of the relay 80 in response to the conduction of the transistor 71. It is energized and is demagnetized by being cut off from the power supply by the non-conduction of the transistor 71. The double throw switch 102 has a double throw contact 102a.
and both fixed contacts 102b and 102c, and the double-throw contact 102a is connected to the second input terminal of the armature winding of the rotary motor M2. The fixed contact 102b is grounded, while the fixed contact 102c is connected to the positive terminal of the DC power supply B via a switch 82 of a relay 80. However,
The double-throw switch 92 throws the double-throw contact 102a into the fixed contact 102b when the electromagnetic coil 101 is demagnetized, and turns the double-throw contact 102a into the fixed contact 102c in response to the excitation of the electromagnetic coil 101.

In such a case, when the double-throw contact 102a of the double-throw switch 102 is closed to the fixed contact 102b, the double-throw contact 92a of the double-throw switch 92 becomes the fixed contact 9.
2c, the rotary motor M2 switches to relay 8.
Power is supplied from the DC power source B through the zero switch 82, the double-throw contact 92a of the double-throw switch 92, and the first input terminal of its armature winding, and the motor rotates normally to open the rear window. Also, when the fixed contact 92b of the double-throw switch 92a in the double-throw switch 92 is closed, the double-throw contact 102a of the double-throw switch 102
is applied to the fixed contact 102c, the rotary motor M2 is supplied with power from the DC power source B via the switch 82 of the relay 80, the double-throw contact 102a of the double-throw switch 102, and the second input terminal of its armature winding. Reverse to close the rear window. Note that the rotating electric motor M2 stops when the double-throw contact 92a is turned on to the fixed contact 92b and the double-throw contact 102a is turned on to the fixed contact 102b.

In this embodiment configured as described above, if the ignition key of the sports wagon is inserted into the ignition key cylinder in the vehicle interior and the ignition switch IG is closed,
The relay 20 turns on the double-throw contact 22c of the double-throw switch 22 to the fixed contact 22b by energizing the electromagnetic coil 21 based on power supplied from the linear power supply B, and at the same time, the transistor 60 is supplied with power in the same way as the electromagnetic coil 21, and the transistor 60 is turned on. 61 is made conductive. At this time, the fully closed detection switch 30a is in the fully closed detection state when the rear window is fully closed, and both storage detection switches 12 and 13 are in the fully closed detection state when the wiper blade is stored in the second storage position. Both are in the storage detection state.

At this stage, when the wiper switch 11 is operated, the rotating electric motor M1 is connected to the fixed contact 22b and the double-throw contact 22c of the double-throw switch 22 from the DC power supply B.
The wiper blade is rotated by being supplied with electricity through the wiper blade, and the wiper blade is repeatedly moved back and forth across the wiping area of the rear window. At this time, each storage detection switch 12,
13 are both closed by movement of the wiper blade into the wiping area. After that, when the wiper switch 11 is put into the non-operating state, the rotary electric motor M1 continues to rotate by being supplied with power from the DC power supply B via the double-throw contact 22c of the double-throw switch 22 and the storage detection switch 12, and the electromagnet 14 is turned off. The electromagnetic coil is supplied with power and excited via the storage detection switch 12 in the same way as the rotary motor M1. Then, when the wiper blade reaches its first storage position, the rotary electric motor M1 stops in response to the change of the storage detection switch 12 to the storage detection state, and at the same time, the electromagnet 14 activates the plunger based on the electromagnetic force. The displacement retracts the wiper blade into its second retracted position. At this time, the storage detection switch 13 and the storage switch 12 enter the storage detection state.

In this state, the ignition key is released from the ignition key cylinder in the vehicle interior and inserted into the key cylinder outside the rear of the sports wagon to open the double-throw contact 41 of the window switch 40. When the fixed contact 42 is connected, the transistor 6 of the transistor circuit 60
1 becomes non-conductive, and the relay 20 demagnetizes its electromagnetic coil 21, so that the double-throw contact 2 of the double-throw switch 22
2c to the fixed contact 22a to cut off the wiper switch 11 from the DC power supply B, and the relay 80 closes the switch 82 by exciting the electromagnetic coil 81 based on the power supplied from the DC power supply B, and the transistor 71 of the transistor circuit 70 However, the temperature detection switch 1
When the transistor 72 is non-conductive based on the storage detection state of No. 3, power is supplied from the DC power supply B through the switch 82 and the relay 90 becomes conductive. By energizing the coil 91, the double-throw contact 92a of the double-throw switch 92 is connected to the fixed contact 92c.

At this time, since the double-throw contact 102a of the double-throw switch 102 in the relay 100 is connected to the fixed contact 102b, the rotating electric motor M
2 is supplied with power from the DC power supply B through the switch 82 of the relay 80 and the fixed contact 92c and double-throw contact 92a of the double-throw switch 92 in the relay 90, and rotates forward to open the rear window and open the fully closed detection switch 30a. On the other hand, window switch 4
When the double-throw contact 41 of 0 is connected to the closing-side fixed contact 43, the rotary motor M2 is grounded due to the connection of the double-throw contact 92a of the double-throw switch 92 to the fixed contact 92b, and the transistor 71 Except for the point where the electromagnetic coil 101 of the relay 100 is energized based on the conduction of the relay 100 and the double-throw contact 102a of the double-throw switch 102 is turned on to the fixed contact 102c, power is supplied and reversed to close the rear window. The action is substantially the same as when opening the rear window.

By the way, as mentioned above, when the wiper switch 11 is closed when the ignition switch IG is closed,
While the rotary electric motor M1 is rotating to reciprocate the wiper blade along the wiping area of the rear window, the ignition key is removed from the ignition key cylinder in the vehicle interior. When released, the ignition switch IG opens, the transistor 61 of the transistor 60 becomes non-conductive, and the relay 20 is operated by closing the double throw contact 22c of the double throw switch 22 to the fixed contact 22a based on the demagnetization of the electromagnetic coil 21. Cut off switch 11 from DC power supply B,
The rotary electric base M1 immediately stops the wiper blade in the wiping area of the rear window by stopping its rotation. At this time, it is assumed that the wiper blade is not in the first and second storage positions, and both storage detection switches 12 and 13 are in the closed state.

After that, if the ignition key is inserted into the key cylinder on the outside of the rear of the sports wagon and the double-throw contact 41 of the window switch 40 is connected to the open-side fixed contact 42, the relay 80 Under the action of 50a,
The switch 82 is closed by the excitation of the electromagnetic coil 81 based on the power supply from the DC power supply B, thereby allowing the power supply from the DC power supply B to the double throw switch 92 of the relay 90. However, when the storage detection switch 13 is in the closed state and the storage detection switch 13 is grounded, the transistor 72 of the transistor circuit 70 is supplied with power from the DC power supply B through both resistors 72a and 72b, and becomes conductive, maintaining the transistor 71 in a non-conductive state. . Therefore, as described above, even if the window switch 40 is operated to open the rear window, the electromagnetic coil 91 of the relay 90 is turned off by the transistor 7 which is in a non-conducting state.
1, the DC power source B is cut off and the demagnetized state is maintained, so the double throw switch 92 becomes the double throw switch 9.
2a is kept disconnected from the fixed contact 92c. In other words, the rotary electric motor M2 is connected to the double-throw switch 92.
The power supply from the DC power supply B via the DC power source B is not allowed and remains stopped, and as a result, the rear window maintains the fully closed state, and the occurrence of the problem described in the prior art of this specification is ensured. Can be prevented.

Further, when the control device according to the present invention is not operating, the fully closed detection switch 30a opens based on the slight opening of the rear window due to some cause, and the retraction detection switch 13 opens the rear window due to some cause. If a situation occurs in which the wiper blade is closed due to detachment from the second storage position, etc., closing the operation switch 30b short-circuits the fully closed detection switch 30a which is in the open state. be able to. Therefore, if you operate the ignition switch IG in such a short-circuit condition,
The relay 20 connects the electromagnetic coil 2 in the same manner as described above.
1, the fixed contact 2 of the double-throw switch 22
2b and the double-throw contact 22a to allow the wiper switch 11 to be supplied with power from the DC power supply B.

Thereafter, by operating the wiper switch 11, the rotary motor M1 is rotated in response to the power supply from the DC power supply B via the double-throw switch 22 in the same manner as described above, and the wiper blade is operated for wiping. By putting the wiper switch 11 in the non-operating state, the wiper blade is stored in its second storage position under the action of the electromagnet 14 in the same manner as described above, and the storage detection switch 13 is brought into the storage detection state, and the transistor 72 base is grounded, and at this stage the wind switch 40
By operating the rear window, the rear window can be fully closed or opened properly and automatically in the same manner as described above based on the non-conduction of the transistor 72 and the conduction of the transistor 71. This means that even if the fully closed detection switch 30a is opened and the retraction detection switch 13 is closed for some reason, both the rear wiper and the drive mechanism can be operated by operating the operation switch 30b. This means that it can be easily released from each inoperable state and put into a proper operational state.

In the above embodiment, an example was explained in which the device of the present invention was applied to control the opening/closing rear window and rear wiper of a sports wagon.
The present invention is not limited to this, and the present invention may be applied to any vehicle as long as it is equipped with an openable rear window and a rear wiper.

Furthermore, in the embodiment described above, an example has been described in which the transistor circuit 70 prohibits the excitation of the electromagnetic coil of the relay 90 in relation to the storage detection switch 13; however, the present invention is not limited to this; In place of the transistor circuit 70, an electric circuit is adopted in place of the transistor circuit 70, which prohibits the excitation of the electromagnetic coil of the relay 90 when the storage detection switch 13 is open, and allows the excitation of the electromagnetic coils of both the relays 90 and 100 when the storage detection switch 13 is open. You can.
