Description

[Detailed Description of the Invention] (Industrial Application Field) In the present invention, the opening/closing body opens and closes the roof opening by forward and reverse rotation of the motor, and in conjunction with the opening/closing of the opening/closing body, moves between the upright position and the retracted position. The present invention relates to an electric sunroof device for an automobile, in which a wind deflector that swings up and down is provided near the front edge of the roof opening.

(Prior Art) As a conventional electric sunroof device for an automobile, there is one disclosed in Publication No. 39065/1983, for example.

This conventional example prevents a hand or head from being trapped between the front edge of the roof opening and the opening/closing body when closing the opening/closing body, and allows the wind deflector to be slid forward. and is provided with a stop switch that operates when the wind deflector slides forward, and when a hand or head hits the wind deflector when closing the opening/closing body, the wind deflector slides forward and the stop switch is activated, This stops power supply to the motor.

However, in such conventional examples, (1) the stop switch is configured to operate when the wind deflector slides forward, but when a hand or head hits the wind deflector, Depending on how the wind deflector hits, there is a possibility that the wind deflector will swing but not slide forward, so even if your hand or head hits the wind deflector, the stop switch will not work properly. (2) Since the swingable wind deflector is provided so as to be able to slide forward, the support structure becomes complicated, and (3) Since a space is required for the wind deflector to slide forward, there is a problem in that the amount of opening of the roof opening becomes smaller by the amount of space.

(Problems to be solved by the invention) The present invention has been developed by focusing on the above-mentioned conventional problems. To provide an electric sunroof device for an automobile in which a safety switch for stopping operation is operated reliably, thereby surely preventing hands and heads from being caught between the front edge of a roof opening and the opening/closing body. It is an object.

The NO side is off.

Next, a switching mechanism for switching the first switch S1, second switch S2, and third switch S3 will be explained based on FIGS. 1, 6, and 7.

A cam gear 6 that rotates forward and backward in conjunction with the motor M.
A rotary shaft 60a of 0 is rotatably supported by a switch cover 61 and a gear case 69, and the tip of the rotary shaft 60a projects upward from the switch cover 61. The cam gear 60 includes a first
Second and third cam plates 62, 63, and 64 are fixed to rotate integrally with the cam gear 60, and the cam gear 60 is attached to the tip of the rotating shaft 60a.
Similarly, a fourth cam plate 65 is fixed to rotate integrally.

Each cam plate 62, 63, 64, 65 has a projection 6.
2a, 63a, 64a, and 65a are formed, respectively. Each protrusion 62a, 63a, 64a, 6
Each end of the first movable piece 66, the second movable piece 67, the third movable piece 68, and the movable element S30 of the third switch S3 protrudes within the rotation locus of the switch 5a.

The right end of the first moving piece 66 is connected to the mover S20 of the second switch S2, and the right end of the second moving piece 67 is connected to the mover S20 and the mover S10 of the first switch S1 via the solenoid pusher 70a. The right ends of the pieces 68 are in contact with the mover S10, respectively.

This solenoid pusher 70a is movable in a direction perpendicular to the paper surface of FIG.
An operating position where the moving piece 67 is pushed by the protrusion 63a of the second cam plate 63 and can be pressed against the movers S10 and S20 via the solenoid pusher 70a, and the second moving piece 67 and the mover S10. ,S20
The movable member S10, S20 can be slid between a non-operating position in which the movers S10 and S20 cannot be pressed. The solenoid pusher 70a is
When the solenoid 70 in the control circuit 50 is energized, it is in the operating position, and when it is not energized, it is in the non-operating position due to a biasing force (not shown).

Here, when each of the movers S10, S20, S30 of each switch S1, S2, S3 is in the protruding position shown in FIG. 6, each contact piece of the first switch S1, second switch S2 is switched to the contact NC side. The third switch S3 is turned off. In addition, each mover S1 of each switch S1, S2, S3
0, S20, and S30 are pushed in from the protruding position, each contact piece of the first switch S1 and second switch S2 switches to the contact NO side, and the third switch S
3 is configured to be turned on.

Further, each of the protrusions 62a, 63a, 64a,
Regarding the positional relationship of 65a, when the opening/closing body 2 is fully opened, the protrusion 62a of the first cam plate 62
pushes the end of the first moving piece 66, and when the opening/closing body 2 is fully closed, the projection 63a of the second cam plate 63 pushes the end of the second moving piece 67, and the motor M is further moved from the fully closed position. When the rear part of the opening/closing body 2 is tilted up by rotation, the protrusion 6 of the third cam plate 64
4a pushes the end of the third moving piece 68, and when the opening/closing body 2 is within the range from about 150 mm before the fully closed position to near the fully closed position (the range indicated by θ1 in FIG. 7), Projection 65a of fourth cam plate 65
is configured to push the mover S30.

Therefore, regarding the third switch S3, when the opening/closing body 2 is within the range from the fully closed position to the vicinity of the fully closed position (the range indicated by θ2 in FIG. 7),
The protrusion 65a of the fourth cam plate 65 is away from the mover S30, and the third switch S3 is off.

Next, the operation of the electric sunroof device 1 for an automobile having the above configuration will be explained.

First, when the opening/closing body 2 is opened as shown in FIG. 2, the wind deflector 5 is in the upright position as shown in FIG. 3, and at this time the protrusion 5b is located away from the safety switch S4.

With the opening/closing body 2 open in this way, when the contact piece of the operating switch S5 is switched to the fully closed side contact S51 in order to close the opening/closing body 2, the current flows from the positive terminal to the fully closed side of the operating switch S5. contact S51,
Since the flow passes through the contact NC of the third electromagnetic relay switch R3 to the coil of the second electromagnetic relay coil R2, the contact piece of the second electromagnetic relay coil R2 becomes the contact.
Switches to NO side. As a result, a normal rotation circuit that rotates the motor M in the normal direction includes the contact NO of the second electromagnetic relay coil R2, the contact NC of the first switch S1, the switch coil C2, the motor M, the circuit breaker B,
Contact point of switch coil C1 and second switch S2
NC and contact NC of first electromagnetic relay coil R1
The motor M rotates normally.

The forward rotation of the motor M causes the opening/closing body 2 to slide forward from the position shown in FIG. Also, motor M
In conjunction with the forward rotation of the cam gear 60, the cam plates 62, 6
3, 64, and 65 in the counterclockwise direction in FIG. 7 (however, FIG. 7 shows the state when the opening/closing body 2 reaches the fully closed position).

When the opening/closing body 2 advances to a position approximately 150 mm before the fully closed position, the projection 65a of the fourth cam plate 65 pushes the slider S30 of the third switch S3, and the third switch S3 is turned on. The third switch S3
The on state is maintained while the opening/closing body 2 is within the range θ1, and when the opening/closing body 2 moves forward to near the fully closed position (when the opening/closing body 2 enters the range θ2), the protrusion 65a moves toward the slider S30. The third switch S3 is turned off again.

In this way, while the opening/closing body 2 is moving forward within the range θ1, the front edge 4a of the roof opening 4 and the opening/closing body 2
If a hand or a leg is about to be caught between the two, the hand or head will hit the wind deflector 5 at the position shown by the two-dot chain line in FIG. At that point, you can evacuate your hands and head, or if you have time, grab the wind deflector to bring it down. As a result, the wind deflector 5 swings from this position to the retracted position shown by the chain line in FIG. 4, the protrusion 5b presses the safety switch S4, and the safety switch S4 is turned on.

At this time, the third switch S3 is on, so when the safety switch S4 is turned on, the coil of the third electromagnetic relay switch R3 is energized, and its contact R30 separates from the contact NC, and the contact R31 contacts the contact NO. . When contact R31 contacts contact NO, current flows from the positive terminal through contact R31, the coil, and the third switch S3.
The coil remains energized until the switch S3 is turned off.

As mentioned above, when the contact piece R30 separates from the contact NC, the normal rotation circuit, which had been closed until then, opens, and the normal rotation of the motor M is stopped, thereby preventing hands and heads from being caught. .

In this state, the contact R30 is maintained apart from the contact NC, so the operating switch S5
Even if the switch S5 is once returned to the neutral position and the operating switch S5 is again switched to the fully closed contact S51, the normal rotation circuit remains open and the opening/closing body 2 cannot be moved forward. Therefore, in such a case, the operating switch S5 is switched to the fully open contact S50, and the opening/closing body 2 is slid rearward to the position where the third switch S3 is turned off. When the third switch S3 is turned off, energization to the coil of contact R3 is terminated, so that contact R30 contacts contact NC and contact R
31 leaves contact NO.

As the contact piece R30 comes into contact with the contact point NC,
When the operating switch S5 is switched to the fully closed contact S51, the normal rotation circuit is closed and the opening/closing body 2 slides forward again. When the opening/closing body 2 advances to the fully closed position without getting your hands or head caught, the third switch S
The third mover S30 is connected to the protrusion 65 of the fourth cam plate 65.
a, the third switch S3 is turned off, and the wind deflector 5 is swung from the upright position to the position shown in FIG. 4 in conjunction with the opening/closing body 2. At this time, the protrusion 5b is connected to the safety switch S.
Even if 4 is pressed and the 3rd switch S is turned on,
3 is off, the motor does not stop. In this way, when the opening/closing body 2 moves forward to near the fully closed position (when the opening/closing body 2 enters the range θ2), there is no risk of hands, heads, etc. being caught, so the third switch S3 is closed. is off, disabling safety switch S4.

When the opening/closing body 2 slides to the fully closed position, the seventh
As shown in the figure, the protrusion 63a of the second cam plate 63 presses the end of the second moving piece 67, so the solenoid pusher 70a moves to the right in FIG. S10 and the mover S20 of the second switch S2 are pushed in. As a result, each of the contacts of the first switch S1 and the second switch S2 is switched to the contact NO side, the normal rotation circuit is opened, and the normal rotation of the motor M is stopped. At this time, the wind deflector 5 is in the retracted position shown by the chain line in FIG.

When the operating switch S5 is operated again to the fully closed side contact S51 side with the opening/closing body 2 reaching the fully closed position and the motor M stopped, the normal rotation circuit is closed again and the motor M is Further forward rotation from the fully closed position. This forward rotation tilts up the rear part of the opening/closing body 2, and when the rear part is completely tilted up, the projection 64a of the third cam plate 64 pushes the end of the third moving piece 68 to the right in FIG. ,
Since the right end portion of the third moving piece 68 pushes the mover S10 of the first switch S1, the first switch S1
The contact piece is switched to the contact NO side, the normal rotation circuit is opened, and the motor M is stopped.

When the operating switch S5 is operated to the fully open contact S50 side in this tilted up state, the coil of the first electromagnetic relay coil R1 is energized, and its contact piece becomes the contact.
A reversing circuit that switches to the NO side and reverses the motor M is connected to the positive terminal and the first electromagnetic relay coil R1.
contact NO, second switch S2 contact NC, chain coil C1, circuit breaker B, motor M, circuit breaker C2, first switch S1 contact NC, and second electromagnetic relay coil R2 contact
Closed by NC. As a result, the motor M reverses, the rear part of the opening/closing body 2 is tilted down, and at the fully closed position where the tilt down is completed, each contact piece of the first switch S1 and the second switch S2 is turned to the contact NO side as described above. The reverse rotation circuit is opened and the motor M is stopped.

When the operating switch S5 is moved to the fully open side contact S50 in order to open the opening/closing body 2 in the fully closed position, the reversing circuit is closed again, and the opening/closing body 2 in the fully closed position slides rearward, causing the opening/closing body 2 in the fully closed position to slide back. Reach the closed position. When the opening/closing body 2 reaches the fully open position, the protrusion 62a of the first cam plate 62 pushes the end of the first moving piece 66, which moves the first moving piece 66 to the right and switches the second switch S2. Push in the mover S20 and switch the contact piece of the first switch S1 to the contact NO side.
This opens the reversing circuit and stops the motor M from reversing.

According to the above embodiment, when the wind deflector 5, which is in the upright position as shown in FIG. 3, is pushed down and swung to the retracted position shown by the chain line in FIG. Since the closing operation of the wind deflector 5 can be stopped, if a person who has his/her hand or head out of the roof opening 4 notices that the opening/closing body 2 is sliding in the closing direction, he or she can stop the wind deflector 5 by pushing down and shaking it. Just by moving it, you can instantly avoid dangerous situations where your hands or head get caught.

Further, according to the above embodiment, when the normal rotation circuit that advances the opening/closing body 2 is opened due to a hand or head being caught, the opening/closing body 2 moves to the position where the third switch S3 is turned off. Since the forward rotation circuit cannot be closed until after the driver has returned the robot to the rear, the danger of the forward rotation circuit being closed with a hand or head caught is avoided. There is.

(Effects of the invention) According to the electric sunroof device for a car according to the invention, when a hand or head hits the wind deflector when closing the opening/closing body, the wind deflector swings to the retracted position, and the swinging allows safety. Since the switch is activated and the movement of the opening/closing body in the closing direction is stopped, it is possible to reliably prevent hands or heads from getting caught between the front edge of the roof opening and the opening/closing body, and the movement of the opening/closing body in the closing direction can be prevented. Since the safety switch is simply placed below the movable wind deflector, the structure is extremely simple, and since the wind deflector is not slid forward as in the conventional example, the roof opening can be opened. Sufficient quantity can be secured.
