Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a driving control device for a sliding roof that slidably opens and closes an opening provided in the roof of a vehicle, and more particularly, the present invention relates to a sliding roof drive control device that slidably opens and closes an opening provided in the roof of a vehicle. The present invention relates to a drive control device.

In recent years, as shown in FIG. 1, an opening 2 is provided at the front of a roof 1, and a sliding roof 3 is slid back and forth through the opening 2 via a guide rail or the like to open and close the opening 2. Cars designed in this manner are in practical use.

The above-mentioned sliding roof 3 is moved electrically or manually, and a device as shown in FIG. 2 is conventionally known as a device for moving the sliding roof 3 electrically.

The device shown in FIG. 2 connects one end and the other end of a motor 4 that drives the sliding roof 3 to an opening switch 5a and a closing switch 5b of an operating switch 5, respectively, so that one end and the other end of the motor 4 are normally connected to the opening switch 5a and the closing switch 5b. respectively ground contact 5a
-7 and 55-1, and when opening the sliding roof 3, connect the opening switch 5a to the opening contact 5a-2, and connect the key switch 5a to the opening contact 5a-2.
, one end of the motor 4 is connected to the positive electrode of the battery 7, and the motor 4 is rotated in the normal direction to open the sliding roof 3. On the other hand, when the sliding roof 3 is to be closed, the closing switch 5b is closed. The other end of the motor 4 is connected to the moving contact 5b-2, the other end of the motor 4 is connected to the positive electrode of the battery 7 through the key switch 6, and the motor 4 is reversed to close the sliding roof 3.

In the above-mentioned device, the sliding roof 3 is opened and closed relatively quickly by the motor 4 without stopping midway. There was a risk that a hand or the like would be caught between the opening 2 of the roof 1 and the sliding roof 3.

Therefore, in view of the above problems, for example,
As shown in Japanese Patent No. 6721, as a closing switch 5b, the ground contact 5 is closed by pressing the push button in one step.
A push-button type switch that switches from b-1 to the first closing contact 5b-2 and from the first closing contact 5b-2 to the second closing contact 5b-3 by pressing the push button in two steps. Using the actuation switch 5 provided with the above first closing moving contact A5
Between b-2 and the key switch 6, there is a relay contact of a roof relay 9 that detects the position of the sliding roof 3 and is deenergized when the detection switch 8 is turned off when the opening becomes below a certain level. 9a and the second closing contact 5b-3 to the key switch 6, the sliding roof 3 reaches a certain position with one step of the push button of the closing switch 5b and the detection switch is activated. When the switch is turned off, the relay contact 9a is turned off, the power supply to the motor 4 is cut off, and the sliding roof 3 is stopped.Then, the second step of operation of strongly pressing the push button of the closing switch 5b is performed to close the roof. The moving switch 5b is connected to the second closing moving contact 5.
A system has been proposed in which the sliding roof 3 is not fully closed unless the switch is switched to b-3, thereby ensuring the safety of the occupants.

However, in the above-mentioned slide ink 'rv-f device, the closing switch 5b of the actuation switch 5 is different from the opening switch 5a and has a first closing contact 5b-2 having a large contact capacity through which the load current of the motor 4 flows. and second closing moving contact 5
In addition to requiring the two closing contacts of b-3, it also required a two-stage operation mechanism, and the operating switch 5 could not be constructed with switches with the same type of contact structure, resulting in a complicated structure. .

Moreover, in this case, if the closing switch 5b is operated incorrectly,
It is necessary to take special measures to prevent the sliding roof from stopping once in a predetermined position due to sudden second-stage operation.

On the other hand, as a further improvement on the above-mentioned conventional example, for example, as shown in Japanese Patent Laid-Open No. 56-93987, the sliding roof is restarted from the stopped position and completely closed by operating the operation switch again. Something has also been proposed.

However, since this device uses a relay that is self-holding and interrupts the motor circuit, if the operation switch is operated again immediately after the operation switch is turned off until the self-holding is reliably resolved, the relay may cause hunting, and the sliding roof may not be able to be closed smoothly.

The present invention has been made in view of the above-mentioned shortcomings in conventional sliding roof drive control devices, and includes a relay that is turned off when the sliding roof is opened less than the set opening level by an off signal from an operation switch that closes the sliding roof. By providing a holding circuit that turns on the relay, the above-mentioned off signal turns the relay on again and holds it self, so that the sliding roof can be closed in two stages using a simple operation switch with a mechanism and contact configuration. The purpose of this invention is to provide a drive control device.

For this reason, the present invention provides a motor for driving the opening and closing of a sliding roof provided on the roof portion of a vehicle body, an opening-side drive circuit and a closing-side drive circuit for operating the motor to open and close the sliding roof, and an opening-side drive circuit and a closing-side drive circuit for operating the motor to open and close the sliding roof. A first operation switch connected to a drive circuit and a second operation switch connected to a closing side drive circuit, the first operation switch being connected when detecting that the sliding roof is at a set opening position; a position detection switch having a second contact; a relay that is connected to the first contact of the position detection switch and turns off when the sliding roof is below a set opening; and a relay that is turned on by an off signal from a second operation switch and detects the position. a holding circuit configured with a self-holding contact of a relay connected to a second contact of the switch and holding the relay in an on state, and a normally open contact of the relay connected to the closing side drive circuit in series with the second operating switch It is characterized by the connection of

Hereinafter, the present invention will be specifically described with reference to the accompanying drawings.

On the other hand, a position detection switch 15 for detecting the position of the sliding roof 3 is attached to the space 19 side of the frame 18, and as shown by the two-dot chain line in FIG. When the distance g between the front edge 2a of the opening 2 and the rear edge 3b of the sliding roof 3 becomes, for example, 20 cIrL or less, the rear edge 3b of the sliding roof 3
is separated from the actuator 150 of the position detection switch 15, and the sliding roof 3 of the actuator 150
The pressure caused by this is released.

In the temporary stop circuit 14, when the front operation switch 12 or the rear operation switch 13 is operated, the sliding roof 3 is operated to close, the distance g becomes 20 (11771), and the pressure of the actuator 150 of the position detection switch 15 is released. Then, upon receiving a signal from the position detection switch 15, the motor 11 is stopped and the sliding roof 3 is stopped.

The stop circuit 14 operates when the operation of the front operation switch 12 or the rear operation switch 13 is once stopped.
The sliding roof 3 is prevented from sliding to the fully closed position unless an off signal is output from.

In FIG. 4, 20 is an opening provided in the frame 18 to communicate the opening 2 of the roof 1 with the vehicle interior, and 21 is a front header for reinforcing the front end of the roof 1.

Next, a specific circuit of the drive control device for the sliding roof 3 shown in FIG. 4 is shown in FIG.

As shown in FIG. 5, the front operation switch 12 is a first switch that opens and closes the sliding roof 3, respectively.
Consisting of an operation switch 31f and a second operation switch 32f, the first operation switch 31f connects a normally open contact 31fa, a normally closed contact 31fb, and a movable contact 31fc.
The operation switch 32f has a normally open contact 32fa and a normally closed contact 32.
fb and a movable contact 32fc.

Similarly to the above, the rear operation switch 13 also includes a first operation switch 31r and a second operation switch 32r that open and close the sliding roof 3, respectively.
The first operation switch 31r has a normally open contact 31ra, a normally closed contact 31rb, and a movable contact 31rc, and the second operation switch 32r has a normally open contact 32ra, a normally open contact 32rb, and a movable contact 32rc.

In the front operation switch 12, the first operation switch 31
The motor 11 is connected between the movable contact 31fc of the f and the movable contact 32fc of the second operation switch 32f, while the first operation switch 31f and the second operation switch 3
The normally open contacts 31fa and 32fa of 2f are both connected to a power supply line 35 connected through a key switch 34 to the positive electrode of a battery 33 whose negative electrode is grounded.

On the other hand, in the rear operation switch 13, the normally open contact 31ra and the normally closed contact 31rb of the first operation switch 31r
are connected to the power line 35 and the ground, respectively, and a normally open contact 32ra and a normally closed contact 32rb of the second operation switch 32r are connected to the power line 35 and the ground, respectively.

Between the movable contact 31 rc of the first operation switch 31r of the rear operation switch 13 and the normally closed contact 31fb of the first operation switch 31f of the front operation switch 12, there is a normally open contact of relay X1 of the temporary stop circuit 14. In addition, the movable contact 32rc of the second operation switch 32r of the rear operation switch 13 and the normally closed contact 32fb of the second operation switch 32f of the front operation switch 12 are connected to each other.

Although not specifically illustrated as the above-mentioned front operation switch 12 and rear operation switch 13, for example,
A knob swingably supported on a support shaft is normally in a neutral position, and a well-known scene-type switch can be used in which the end of the knob is pressed to perform a necessary operation.

Next, the primary stop circuit 14 connects the relay X1. X2 and diode D1. Consists of D2.

Relay coil X1 of the above-mentioned relay X1 (hereinafter, the relay and the relay coil will be denoted by the same symbol.

) is connected between the power supply line 35 and the normally open contact 15a of the position detection switch 15, while the relay coil X2 of the relay X2 and the normally open contact X2-a as a self-holding contact of the relay It is connected in series between the line 35 and the normally closed contact 15b of the position detection switch 15.

Normally open contact 1 of relay coil X1 and position detection switch 15
Connection point 36 with 5a and relay coil X of relay X2
2 and its normally open contact X2-a are connected to the anode and cathode of the diode D1, respectively. The anode and cathode of a diode D2 are connected to the contact point 38 with the movable contact point 32fc.

The movable contact 15c of the position detection switch 15 is connected to ground.

In this position detection switch 15, a movable contact 15c is driven by the actuator 150, and is switched and connected to a normally open contact 15a, which is a first contact, and a normally closed contact 15b, which is a second contact.

Next, the operation of the circuit shown in FIG. 5 will be explained.

Now, the sliding roof 3 is fully open, the movable contact 15c of the position detection switch 15 is connected to the normally open contact 15a, the key switch 34 is on, and the front operation switch 12 and rear operation switch 13 are Assuming that none of them are operated, position detection switch 1
Since the movable contact 15c of No. 5 is connected to the normally open contact 15a side, the relay X1 is on and its normally open contact X1-a is on, and the motor 11 stops with both ends connected to ground. are doing.

In the above state, for example, by operating the second operation switch 32f of the front operation switch 12, as shown by the dotted line in FIG.
When the movable contact 32fc is connected to the normally open contact 32fa side, the connection point 38 is connected to the power supply line 35, so the voltage of the battery 33 is applied to the motor 11, and the motor 1
1 rotates and the sliding roof 3 starts its closing operation.

Further, when the connection point 38 is connected to the power supply line 35, the diode D2 is turned off, the relay X2 is turned off, and its normally open contact X2-a is also turned off.

By continuing the operation of the second operation switch 32f of the front operation switch 12, the distance g between the front end 3a of the sliding roof 3 and the front edge 2b of the opening 2 of the roof 1 becomes
As explained in FIG. 4, when the voltage reaches 20 crrL, the movable contact 15c of the position detection switch 15 switches to the normally closed contact 15b side, as shown by the dotted line in FIG.

By the way, at this time, the relay X2 is off and its normally open contact X2-a is open, so the diode D1 is also off and the relay X1 is turned off.

Therefore, the normally open contact X1-a of the relay X1 is turned off, the motor 11 is stopped, and the sliding roof 3 is stopped.

As long as the operation of the second operation switch 32f is continued, the relay X2 is turned off and the sliding roof 3 remains in the stopped state, thereby ensuring the safety of the occupants.

Therefore, once the operation of the second operation switch 32f is interrupted, the movable contact 32fc changes to the normally closed contact 32.
fb side, the connection point 38 is connected to ground, the diode D2 is turned on, the relay X2 is turned on, and its normally open contact X2-a is also turned on, so that the relay X2 is self-holding.

Also, by turning on the normally open contact X2-8, relay X1
is also turned on, and its normally open contact X1-a is also turned on again.

Therefore, in the above state, when the second operation switch 32f of the front operation switch 12 is operated again and its movable contact 32fc is connected to the normally open contact 32fa side, the motor 11 is activated by the above-described self-holding action to keep the relay X1 normally open. Since the opening contact X1-a is turned on, it rotates again to close the sliding roof 3.

If the above-mentioned re-operation of the second operation switch 32f is continued for a certain period of time, the sliding roof 3 is fully closed.

The second operating switch 32r of the rear operating switch 13 also operates the sliding roof 3 in exactly the same manner as above.
can be fully closed in two stages.

Next, when opening the sliding roof 3, the second operation switch 32f of the front operation switch 12 is
The movable contact 32fc is connected to the normally closed contact 32fb, and the second operation switch 32r of the rear operation switch 13 is connected to the normally closed contact 32rb, and the movable contact 32rc is connected to the normally closed contact 32rb.
8 is always connected to ground, so relays X1 and
2 are movable contacts 15c of the position detection switch 15.
is always on, regardless of its position.

Therefore, each normally open contact X of the above relays X□ and X2
, -3 and X2-a are also turned on regardless of the position of the movable contact 15c of the position detection switch 15,
Either move the movable contact 31fc of the first operation switch 31f of the front operation switch 12 to the normally open contact 31fa side, or set the movable contact 31 of the first operation switch 31f of the rear operation switch 13 to the normally open contact 31fa side.
When rc is operated to the normally open contact 31 ra side, the motor 11 rotates in the opposite direction to the case where the sliding roof 3 is operated to close, and the sliding roof 3 is operated to open without stopping midway.

As described above, the sliding roof 3 can be closed with two operations of a single switch, and the safety of the occupants can be ensured.

Next, a circuit diagram of another embodiment of the present invention is shown in FIG.

The embodiment of FIG. 6 uses a relay X1 of the temporary stop circuit 14 having at least two sets of normally open contacts X1-a1 and Xla2, and Instead of the normally open contact X2-a of the relay X2, the normally open contact X□-a2 of the relay diode D1 and relay X2 by shorting connection points 36 and 37.
and is deleted.

In the case of the circuit shown in FIG. 6, when the sliding roof 3 is closed and the interval g shown in FIG. If the switching time from on to off of the normally open contact X1-a2 is made sufficiently shorter than the switching time of the position detection switch 15, the relay X1 is deenergized and the normally open contacts X1-al and Xl -a2 are both turned off, and the motor 11 is stopped.

To rotate the motor 11 again, if you stop operating the second operation switch 32f of the front operation switch 12 or the second operation switch 32r of the rear operation switch 13,
Connection point 38 is connected to ground to provide self-retention to relay X1 and its normally open contacts X1-al and XI-a.
2 are both turned on, and in this state, if the second operating switch 32f or 32r is operated again, the motor 1 is turned on.
1 rotates again to close the sliding roof 3.

When sliding roof 3 opens, connect point 3
8 is connected to ground, the motor 11 will perform exactly the same operation as the circuit of FIG.

As described above, the sliding roof 3 can also be closed in two stages using the circuit shown in FIG.

Although basic embodiments of the present invention have been described in the above description, the present invention is not limited to the above embodiments, and various configurations can be made within the scope of the gist of the present invention.

For example, the position of the sliding roof 3 is
It can also be detected by the stroke amount of the motor 11, the rotation speed of the motor 11, etc.

As is clear from the detailed description above, the present invention
A normal switch with a simple contact configuration is used as an operation switch in combination with a relay to stop the sliding roof below the set opening, and the off signal from the operation switch turns on the relay again to allow the motor to rotate. As a result, the operation switch mechanism and contact configuration are simple, allowing the use of inexpensive operation switches. However, in order to fully close the sliding roof, it is necessary to interrupt the operation of the operation switch and then repeat the same operation again. There is no risk of accidentally operating the switch, and the operability when fully closing the sliding roof is greatly improved.

Furthermore, in the present invention, the relay that turns on the normally open contact connected to the closed-side drive circuit of the motor is turned on by interrupting (turning off once) the operation of the operation switch, and is self-maintained. Immediately after the interruption, the motor enters a standby state in which it can be driven, and even if the operation is quickly performed again, the sliding roof can be completely closed without causing any hunting or the like.
