The detection switch is turned on and the solenoid is energized to enable operation.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 4, an opening 11 is provided in a roof 10 of an automobile, and a lid 12 that opens and closes the opening 11 is provided. The lid 12 is supported by a moving base 13 via a link 14, the moving base 13 is movably supported on a rail (not shown), and a geared cable 15 for moving the moving base 13 is arranged along the rail. It is set up.

The control device 20 having the drive portion of the geared cable 15 is arranged near the front end of the opening 11 corresponding to the end portion of the geared cable 15.

As shown in FIGS. 2 and 3, the control device 20 is formed by mounting various components on a housing 21 fixed to the roof 10, and fixed to a motor 22 capable of rotating in the forward and reverse directions and a drive shaft 22a of the motor 22. A drive portion is formed by the worm wheel 23 that meshes with the formed worm 22b, and a small gear portion 23a integrally formed with the worm wheel 23 meshes with the geared cable 15.

The transmission gear 2 is attached to the small gear portion 23b of the worm wheel 23.
4 is meshed with the rotary body 30 adjacent to the transmission gear 24, the gear portion 31 of the rotary body 30 is meshed with the small gear portion 24a of the transmission gear 24, and the gear 22 is rotated by the rotation of the motor 22. The rotating body 30 rotates in synchronization with the opening and closing of the lid body 12 caused by the vertical movement of the geared cable 15 as the rotating body 30 rotates.

The system after the transmission gear 24 and the rotary body 30 constitutes a control system for detecting the position or state of the lid 12.

The control system will be described with reference to FIGS. Rotating body 3
The microswitches 40a, 40b are arranged facing the 0 through the pushers 41, 42, 43 and the clutch mechanism 44. The clutch mechanism 44 is interposed only between the pusher 42 and the micro switches 40a and 40b,
The microswitches 40a and 40b are detection switches that detect the rotation angle of the rotating body 30, and switch between a normal contact and an operating contact.

Discs 32, 33, and 34 for position detection are provided on the rotating body 30 in a superposed manner on the gear unit 31. The lowermost disc 32 is provided with a detection protrusion 32a for detecting the sliding fully open state.
The intermediate disk 33 is provided with a detection protrusion 33a for detecting the fully closed state, and is urged by a spring 33b so as to operate only when the door is closed and can stand on one side. Detection member 33 in the stop area (for example, 150 mm before fully closed)
c is attached. The uppermost disc 34 is provided with a protrusion 34a for detecting the tilt fully open state.

The pusher 41 faces the disk 32, and the pusher 42 is the disk 3
3, the pusher 43 faces the disk 34.

The microswitch 40a has a pushed protrusion 45 that switches from the normal contact to the operating contact when pushed, and the microswitch 40b also has a pushed protrusion 46.

In the clutch mechanism 44, the plunger 48 driven by the solenoid 47 is inserted into the frame body 44 a, and the spring 4 that urges the plunger 48 in the direction of pushing it into the solenoid 47.
8a is provided, and the solenoid 47 is energized in a necessary area of the operation stroke when the lid 12 is opened and closed.

In the clutch mechanism 44, the frame body 44a is attached to the plunger 48.
The reason why they are overlapped with each other is as follows.

That is, as a matter of course, the tip end of the plunger 48 is supported so as to be directly moved so as to face the solenoid 47, and is not displaced laterally. On the other hand, the clutch mechanism 44 is interposed between the pusher 42 and the microswitches 40a and 40b in the direction orthogonal to the operation direction of the plunger 48 to connect or disable them.
It requires an element that moves laterally.

The frame body 44a enables this, and moves integrally with the plunger 48 in the operating direction of the plunger 48, but when the tip end portion is pushed from the side,
Although it does not swing, the frame body 44a is configured so that it can swing about the base portion as a center.

When the solenoid 47 is energized, it takes the position shown by the solid line in FIG.
the pushed projections 45, 4 of the microswitch 40a via a
When the solenoid 47 is not energized and is demagnetized, the plunger 48 and the frame body 44a are set at the positions shown by the imaginary lines, and the frame body 44a is set to be unable to transmit the motion by idling. There is.

That is, since the operating directions of the pusher 42 and the pushed projections 45 and 46 are orthogonal to the operating directions of the plunger 48 and the frame body 44a, the solenoid 47 is energized and the plunger 4 is energized.
When 8 is pushed out, the edge portion of one end of the frame body 44a can come into contact with the pushed projections 45 and 46. In this state, when the pusher 42 pushes one side of the frame body 44a, one end of the frame body 44a is pushed. The protrusions 45 and 46 are moved in the same direction and pushed in.

When the solenoid 47 is de-energized and demagnetized and the spring 48a pushes the plunger 48 into the solenoid 47, the edge portion of one end of the frame body 44a is pressed by the protrusion 4.
Since the pusher 42 pushes one side of the frame body 44a in this state, the pusher 42 moves one end of the frame body 44a, but the pushed projections 45, 46 are pushed.
Will not be pushed, and the pushed protrusions 45 and 46 will be in a projecting idling state, and even if the solenoid 47 is energized and operated in that state, the pushed protrusions 45 and 46 will hit the end of the recess from the side and interfere. In this state, the plunger 48 has a positional relationship such that it cannot return, and the plunger 48,
The frame body 44a is configured not to operate and the operation of the pusher 42 is not transmitted to the detection switches 40a and 40b.

As can be seen in FIGS. 1 to 3, the drive shaft 3 of the rotating body 30.
0a has a cam plate 50 fixed thereto, and the cam plate 50 has a detection protrusion 51, and the detection protrusion 51 has a lid 12a.
The detection concave portion 52 of the fully closed region and the detection concave portion 53 of the safe stop region before the full closing are recessed and formed.

A detection switch 60 is arranged on the housing 21 so as to face the cam plate 50, and the detection switch 60 has a pushed protrusion 61 and a normally-closed contact 62 that operates when the pushed protrusion 61 appears and disappears. .

As shown in FIG. 5, the circuit of the control device is a + conducting wire 71.
And-relays RA and RB connected to the energization line 72, operation switches 73 connected to these relays RA and RB, and microswitches 40a and 40 connected to the relays RA and RB
b, an operating coil 47a of the solenoid 47, and a normally-closed contact 62 of a detection switch 60 connected in series to the operating coil 47a. The microswitches 40a and 40b are provided with a circuit breaker 74 and noise-preventing choke coils 75 and 75, respectively. 22 are connected.

The relay RA has an operating coil RA1 and a normally closed contact RA2, and the relay RB has an operating coil RB1 and a normally closed contact RB.
2, the operation switch 73 has a tilting closing side contact 73a and an opening side contact 73b.

Next, the operation will be described.

Although FIG. 6 is an operation chart showing the operation of each element, regarding the microswitches 40a and 40b, the case where both terminals of the motor 22 are short-circuited to act as a motor load brake is described as ON. In Figure 6, NO.
Although only 2 and NO.4 are noted, the same applies to NO.1 and NO.3.

First, from the fully closed state of the lid body 12 shown in FIG.
A case where the lid body 12 is tilted upward and opened as shown in FIG.

When the lid 12 is in the fully closed state, the disc 33 of the rotating body 30 is
The detection protrusion 33a of is located at a position where it pushes the pusher 42, and when stopped, the plunger 48 of the clutch mechanism 44 is retracted, so the position corresponds to the pusher 42, but even if the pusher 42 is pushed, the pushed protrusion 45, No motion is transmitted to 46. The microswitches 40a and 40b are on the normal contact side.

When the operation switch 73 is operated to energize the open side contact 73b, a current flows through the operating coil RB1 of the relay RB, and the normally open contact RB2 is turned on. Therefore, + energizing wire 7
1, normally open contact RB2, micro switch 40, motor 2
2, microswitch 40a, relay RA normally open contact R

When the motor 22 rotates, the drive shaft 22a and the worm 22
The worm wheel 23 is rotated by b, and the pinion 2
The geared cable 15 meshed with 3a is vertically moved, the moving base 13 is moved and the link 14 is raised, and the lid 12 is tilted and opened as shown in FIG. 4 (b).

When the lid 12 is tilted to open, as will be described later, in the vicinity of the fully closed position, the pushed projection 61 of the detection switch 60 engages with the detection recess 52 in the fully closed region of the lid 12 of the cam plate 50, and the operation thereof is performed. Although the relationship with the solenoid 47 has meaning, the solenoid 47 is a functionally meaningless region except near the fully closed position. In this region, the detection protrusion 51 of the cam plate 50 pushes the pushed protrusion 61 of the detection switch 60, the normally closed contact 62 connected in series to the operation coil 47a of the solenoid 47 is turned off, and the operation coil Four
7a is not energized.

When tilted and fully opened, the protrusion 34 of the disk 34 of the rotating body 30
a switches the micro switch 40b to the operation contact side via the pusher 43, both terminals of the motor 22 are short-circuited, the motor load brake is applied, and the lid 12 is stopped.
The status of each switch and device is as shown in column NO1 of FIG.

In order to close the lid 12 which is tilted and fully opened, the operation switch 73 is operated to turn on the tilt closing side contact 73a. Then, the operating coil RA1 of the relay RA is energized, the normally open contact RA2 is turned on, and the + energizing wire 71, the relay RA, the micro switch 40a, the motor 22, the micro switch 40b, and the normally open contact RB2 of the relay RB and the above. On the contrary, a current flows and the lid 12 is closed.

Although a current flows from the micro switch 40b to the ground, the micro switch 40b is connected to the ground regardless of whether it is a normal contact or a moving contact.
The motor 22 regardless of the state of the microswitch 40b
Rotate in the same direction.

The operation of the solenoid 47 is required near the fully closed position of the lid body 12, and the pushed projection 61 of the detection switch 60 is engaged with the detection recessed portion 52 of the fully closed region of the lid body 12 of the cam plate 50.
1 is protruding, and the operating coil 47a of the solenoid 47
The normally-closed contact 62 connected in series with is turned on, and the operating coil 47a is energized.

When the lid 12 is fully closed, the detection protrusion 33a of the disk 33 of the rotating body 30 pushes the pusher 42, and the operating coil 47a of the solenoid 47 is also energized so that the frame 44a can relay the operation. Switches 40a, 40b
Is switched to the moving contact side, both terminals of the motor 22 are short-circuited, the motor load brake is applied, and the lid 12 is stopped. The status of each switch and device is as shown in column NO2 of Fig. 6.

When the lid 12 is slid and opened, the operation switch 73 is operated to turn on the tilting closing side contact 73a. When the lid 12 is stopped, the microswitches 40a and 40b which have been turned off on the moving contact side as shown in column NO2 of FIG.
Of the plunger 4 when the power supply to the operating coil 47a is cut off.
When 8 is retracted, it is returned to the normal contact side and is in the initial state shown in column NO3 of FIG. 6, and even if the operating coil 47a is next energized, part of the frame body 44a is pushed as described above. Protrusion 45,
The microswitch 40 cannot be returned because it interferes with 46.
The normal contact state of a and 40b continues.

Therefore, a current flows through the + energization line 71, the relay RA, the micro switch 40a, the motor 22, the micro switch 40b, and the normally open contact RB2 of the relay RB, and the lid 12 slides open.

When the lid 12 is slid to open, as will be described later, in the vicinity of the fully closed position, the pushed projection 61 of the detection switch 60 engages with the detection recess 53 in the safe stop area of the lid 12 of the cam plate 50, and its operation. Has a meaning in the relationship with the solenoid 47, but the solenoid 47 is a functionally meaningless region except near the fully closed position. In this region, the detection protrusion 51 of the cam plate 50 pushes the pushed protrusion 61 of the detection switch 60, the normally closed contact 62 connected in series to the operation coil 47a of the solenoid 47 is turned off, and the operation coil Four
7a is not energized.

When opening, the detection member 33c hits the pusher 42, but since it is in the falling direction, the pusher 42 passes without being pushed.

The rotating body 30 rotates counterclockwise from the above state in FIGS. 1 and 2, and when the lid 12 rotates to the fully opened state, the pusher 41 rides on the protrusion 32a of the disk 32,
The micro switch 40a becomes the operation contact side, and the motor 2
2. The lid body 12 is stopped, and the lid body 12 is brought into the sliding fully open state shown in FIG. 4 (c). Fig. 6 shows the status of each switch and device.
As shown in column NO3.

To close the lid 12 which is slid and fully opened, the operation switch 73 is operated to turn on the open side contact 73b. A current flows through the operating coil RB1 of the relay RB, and the normally open contact RB2
Turns on. Therefore, + conducting wire 71, normally open contact R
B2, the micro switch 40b, the motor 22, the micro switch 40a, and the normally-open contact RA2 of the relay RA flow current, the motor 22 is activated, and the lid 12 is closed.

Although a current flows from the micro switch 40a to the ground, the micro switch 40a is connected to the ground regardless of whether it is a normal contact or a moving contact.
The motor 22 regardless of the state of the microswitch 40a
Rotate in the same direction.

The solenoid 47 needs to be operated in a region from immediately before the safe stop area before the lid 12 is fully closed to when the lid 12 is fully closed, and the safe stop area before the lid 12 of the cam plate 50 is fully closed is detected. Recess 5
3, the pushed protrusion 61 of the detection switch 60 is applied, and the pushed protrusion 61 is projected.
The normally closed contact 62 connected in series to 7a is turned on, and the operating coil 47a is energized.

When the rotating body 30 rotates, the detection member 33c is pushed by the pusher 42.
Then, the micro switches 40a and 40b come to the operation contact side, and the lid 12 is temporarily stopped. When the opening side contact 73b is turned on again after being stopped once, the motor 22 is restarted in the same manner as described above.

From here until just before the lid 12 is fully closed, the solenoid 4
No. 7 is meaningless in terms of function, and the power supply is cut off as in the above. Immediately before fully closing, the solenoid 47 is energized again in the same manner as described above, and when the lid 12 is fully closed, the detection protrusion 33a hits the pusher 42 and the lid 12 stops in the fully closed state. The state of each switch and device is as shown in column NO4 of Fig. 6.
