Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a sunroof control device that has an opening and a lid for the roof of an automobile, and opens and closes the lid.

``Prior Art'' In recent years, sunroofs have become commonplace in automobiles because they provide an opening in the roof of a vehicle to provide ventilation or a sense of openness.

It is necessary to control the opening and closing of the sunroof lid as necessary, but if it is driven by a motor to open and close, for example, a position detection switch is installed to cut off the current to the motor, and then the motor is driven again. It is necessary to supply current to the motor from another system.

As a conventional sunroof control device, there is one shown in FIG. 10, for example.

That is, detection cam surfaces 1a, 1b, and 1c are provided on a rotating body 1 that rotates forward and backward in synchronization with the opening and closing of the lid, and the pushers 2,
3 and 4 are arranged, and a clutch member 5 for cutting off the operation of the pusher 3 according to the position is arranged, and micro switches 6 and 7 are arranged corresponding to the pushers 2, 4, and the clutch member 5. The clutch member 5 is driven by a solenoid, and when energized, it is in a connected state, and when energized, it is in a disconnected state. This configuration allows the lid of the sunroof to be opened and closed by tilting and sliding.

The forward and reverse operations are switched depending on the relationship between the pushers 2 and 4, and the boundary between the tilting opening/closing and sliding opening/closing operations, that is, the fully closed position, is determined and controlled by the action of the clutch member 5.

``Problem that the invention aims to solve'' However, in such conventional sunroof control devices, when there are two functions to be controlled, such as tilting opening/closing and sliding opening/closing, two micro The problem is that a switch is required, and the detection cam surface of the rotating body is multi-layered, making the whole thing thick.If it is mounted on the roof of a car, it reduces head clearance and impairs comfort. It was hot.

The present invention was developed by focusing on these conventional problems, and has solved the above problems by making the overall structure as thin as possible and hardly reducing the head clearance when installed. The purpose is to provide a sunroof control device.

``Means for Solving the Problems'' The gist of the present invention to achieve this purpose is to provide a sunroof in which an opening and a cover body are provided in the roof of an automobile, and the cover body is opened and closed. The control device includes a rotating body that rotates in synchronization with opening and closing of the lid, and a detection switch that detects the rotation angle of the rotating body, and the outer periphery of the rotating body is divided into at least two regions. a diode that allows current to flow in only one direction is installed between the divided regions, and the detection switch has a pair of electrically insulated sliding contacts, forming a pair. Two sliding contacts are arranged in a direction of rotational displacement of the rotating body and slidingly contact a conductor on the outer periphery of the rotating body, and are arranged so that the position is detected based on the degree of conduction between the sliding contacts, and the pair of sliding contacts The end of the operating stroke is when the conductor spans between the divided regions of the conductor, and the connection direction of the diode is set so that the direction of the current passing through the conductor is opposite to the direction of the current that causes the conductor to operate beyond the end of the stroke. The invention resides in a sunroof control device characterized in that the following is set.

"Function" Therefore, when two sliding contacts are in contact with the same conductor, the detection switch is always on, and one sliding contact is applied to one of the divided conductors.
When one other sliding contact is applied to the other side, it may turn on or turn off depending on the direction of the current, so if you set the current in the direction where it turns off and operate it, it will turn off until then. Since the conductive contacts that were conducting are now opened and turned off, the position can be detected, and after detection, the operating side can reverse the direction of the current by reversing the direction of the current. .

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

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

A control device 20 having a drive section for the geared cable 15 is disposed near the front end of the opening 11 corresponding to the end of the geared cable 15.

As shown in FIG.
Various parts are attached to a housing 21 that is fixed to the housing 21, and includes a motor 22 that can rotate in forward and reverse directions, and a worm 22 that is fixed to a drive shaft 22a of the motor 22.
A driving part is formed by the worm wheel 23 that meshes with the geared cable 15, and the small gear part 23a integrally formed with the worm wheel 23
It meshes with the

A transmission gear 24 is meshed with the small gear portion 23 a of the worm wheel 23 , a rotating body 30 is disposed adjacent to the transmission gear 24 , and a gear portion 31 of the rotating body 30 is engaged with the small gear portion 23 a of the worm wheel 23 .
is meshed with the small gear part 24a of the transmission gear 24, and the rotation of the motor 22 causes the geared cable 1 to
5 moves vertically, and the rotating body 30 synchronizes with the opening and closing of the lid 12 by the geared cable 15.
is starting to rotate.

The system after the transmission gear 24 and the rotating body 30 is the lid body 12.
It forms a control system for detecting the position or status of.

The control system will be explained with reference to FIGS. 1 to 3.
Detection switch 40 facing rotating body 30
A micro switch 50 and a clutch mechanism 60 via a pusher 61 are arranged.

The rotating body 30 is provided with a cam disk 32 and a switch disk 33 in two layers on the gear portion 31, and the cam disk 32 is provided with a protrusion 32a for closing the door and a protrusion 32b for confirming opening the door on the outer periphery. ing.

On the outer peripheral surface of the switch disk 33, a main conductor 34a,
A conductor divided into a first conductor 34b and a second conductor 34c is disposed, and a first diode 35 is disposed between one end of the main conductor 34a and the first conductor 34b.
A second diode 36 is installed between the other end of the main conductor 34a and the second conductor 34c. The first diode 35 and the second diode 36 have the property of allowing current to flow in only one direction.

The detection switch 40 has two electrically insulated sliding contacts 41 and 42.
are arranged so as to be lined up in the direction of rotational displacement of each conductor. When the sliding contacts 41 and 42 of the detection switch 40 come to the position of the first diode 35, the lid 12 is tilted and fully opened, and corresponds to the end of the operating stroke. Similarly, sliding contacts 41, 42
comes to the position of the second diode 36, the lid body 1
2 slides fully open and corresponds to the end of the operating stroke.

Then, when the first diode 35 is tilted and fully opened and the sliding contacts 41 and 42 are in sliding contact across the main conductor 34a and the first conductor 34b, the first diode 35 supplies power with the sliding contact 42 as the positive electrode until then. The current is placed in the opposite direction so that no current flows.

Similarly, when the second diode 36 slides fully open and the sliding contacts 41 and 42 come into sliding contact across the main conductor 34a and the second conductor 34c, the second diode 36 keeps the sliding contact 41 as the positive terminal until then. It is arranged so that the current that was being supplied is in the opposite direction so that it does not flow.

The micro switch 50 has a pressed protrusion 51 that turns off when pressed.

The clutch mechanism 60 includes a plunger 63 driven by a solenoid 62 inserted into a frame 64 and a spring 65 that biases the plunger 63 in a direction to push the plunger 63 into the solenoid 62 . When located between the pusher 61 and the pushed projection 51, the pusher 61 acts as a relay portion capable of transmitting the backward movement of the pusher 61 to the pushed projection 51 of the micro switch 50. The solenoid 62 is always energized when the lid 12 is opened and closed.

When the solenoid 62 is energized, it assumes the position shown by the solid line in FIG. When the solenoid 62 is not energized and demagnetized, the plunger 63 assumes the position shown in the imaginary line, and the pusher 61 moves back and pushes the frame 64 to make it swing, but the tip of the frame 64 is not connected to the micro switch 5.
It is set so that it does not hit the pressed protrusion 51 of 0, misses the swing, and becomes unable to transmit the motion.

As shown in FIG. 5, the circuit of the control device includes a solenoid 62 of a clutch mechanism 60 connected between energized wires 71 and 72, and a detection switch 4
0, a motor 22 is connected via a micro switch 50.

Next, the action will be explained.

First, the case where the lid body 12 is tilted upward from the fully closed state shown in FIG. 4 to be opened will be described.

As shown in FIG. 5, when stationary, energized wires 71,
2 is not energized, the micro switch 50 is in the on state, and the detection switch 40 is connected to the sliding contacts 41 and 42.
Both are in sliding contact with the main conductor 34a of the rotating body 30 and are in the on state. Solenoid 62 of clutch mechanism 60
Since the plunger 63 is not energized, the plunger 63 is retracted to the position shown in phantom lines in FIG.

Therefore, in order to open the door by tilting, an operating switch provided near the driver's seat is operated to one side, and as shown in FIG. 6A, the current is energized so that the energizing wire 71 becomes + and the energizing wire 72 becomes -. In FIG. 1, the sliding contact 42 is on the + side. Then, a current flows through the micro switch 50 and the detection switch 40, so that the motor 22 is started.

When the motor 22 rotates, the worm wheel 23 is rotated by the drive shaft 22a and the worm 22b, the geared cable 15 meshed with the small gear part 23a is driven, and the movable base 13 is moved to raise the link 14 and move the fourth As shown in Figure b, the lid 12 is tilted and opened.

If the energized wires 71 and 72 are energized, the solenoid 62
Since the plunger 63 is also energized, the plunger 63 is pushed out, and the clutch mechanism 60 is in a position where the operation of the pusher 61 can be relayed, as shown by the solid line in FIG.
The rotating body 30 is rotated by the transmission gear 24, the small gear part 24a, and the gear part 31, and the direction thereof is clockwise in FIG.

When the lid 12 is tilted and fully opened, the sliding contact 42 of the detection switch 40 crosses the boundary between the main conductor 34a and the first conductor 34b, and the sliding contact 41 and the sliding contact 42 extends over the main conductor 34a and the first conductor 34b. The current then attempts to flow through the first diode 35, but since the polarity is opposite, it cannot flow, and the current is cut off, causing the motor 22 to stop.

At the same time, the pusher 61 rides on one end of the door opening confirmation protrusion 32b, and if the current is not cut off, pushes the pushed protrusion 51 of the micro switch 50 via the plunger 63 and frame 64 to turn it off and cut off the current. Confirms that there is no movement.
Let go of the operation switch and finally the energized wire 71,
If the power supply to 72 is stopped, the lid 12 and each part will remain in that state. However, since the clutch mechanism 60 stops energizing the solenoid 62, the spring 65 pushes the plunger 63 into a state where the operation of the pusher 61 cannot be transmitted.

To close this tilted and fully opened lid body 12,
When the operation switch is operated in the other direction, the current is applied to the current-carrying wires 71 and 72 with the polarity opposite to that when the switch is opened as shown in FIG. 7a. Then, even though the circuit state is the same, current flows through the first diode 35, so the motor 22 is started in the opposite direction, and the lid 12 is closed through the same transmission path as described above, although the direction is different.

When the current-carrying wires 71 and 72 are energized, the solenoid 62 of the clutch mechanism 60 is activated and the plunger 6 is activated.
3 to a position where the motion can be transmitted, but since the pusher 61 rides on one end of the door opening confirmation protrusion 32b, the frame 64 is biased toward the micro switch 50, and the side edge of the pushed protrusion 51 The pusher 61 does not reach the position where the motion can be transmitted until the pusher 61 is separated from the door opening confirmation protrusion 32b.

The rotating body 30 rotates counterclockwise in FIG. 1 from the above state, and when it rotates to the fully closed state shown in FIG. Push the pressed protrusion 51 of the micro switch 50 to turn off the micro switch 50 as shown in FIG. 7b.

Accordingly, the power supply to the motor 22 is cut off and the motor 22 stops, and the lid body 12 enters the fully closed state shown in FIG. 4a.
Therefore, I let go of the operating switch and connected the energized wire 71.
When the power supply to 72 is stopped, the spring 65 pushes the plunger 63 and the clutch mechanism 60 pushes the plunger 6
1 operation becomes impossible to transmit, and the circuit
The state returns to the state shown in the figure.

Next, when the lid 12 is opened by sliding backward, the lid 12 is in the state shown in FIG. 4a, and the circuit is connected to the fifth
From the state shown in the figure, the operating switch is operated to the other side to energize the energizing wires 71 and 72 with the polarity opposite to that shown in FIG. 6a, as shown in FIG. 8a.

Similarly to the above, the motor 22 is started and the geared cable 15 is driven, thereby moving the movable base 1.
3 moves to the right in FIG. 4 and opens to the sliding fully open position shown in FIG. 4c. At this time, the rotating body 30 rotates counterclockwise in FIG. 1, and the sliding contact 41 of the detection switch 40 has + polarity.

When the lid 12 is fully opened, the sliding contact 41 of the detection switch 40 crosses the boundary between the main conductor 34a and the second conductor 34c, as shown in FIG.
It comes into sliding contact with the conductor 34c. Then, the current tries to flow through the second diode 36, but since the polarity is opposite, the current cannot flow, and the current is cut off and the motor 22 stops.

At the same time, the pusher 61 rides on the other end of the door opening confirmation protrusion 32b, and if the current has not been cut off, it pushes the pushed protrusion 51 of the micro switch 50 through the plunger 63 and frame 64 to turn it off and cut off the current. , to confirm that there is no movement.
When the current to the current-carrying wires 71 and 72 is finally stopped, the lid 12 and each part will stop in that state. Since the clutch mechanism 60 stops energizing the solenoid 62, the spring 65 pushes the plunger 63 into a state where the operation of the pusher 61 cannot be transmitted.

To close the fully opened lid 12, the operation switch is operated in one direction to energize the energizing wires 71 and 72 with the polarity opposite to that used when opening the lid 12, as shown in FIG. Then, even though the circuit state is the same, current flows through the second diode 36, so the motor 22
is activated in the opposite direction, and the lid 12 is closed by the same transmission path as described above, although in a different direction.

When the current-carrying wires 71 and 72 are energized, the solenoid 62 of the clutch mechanism 60 is activated and the plunger 6 is activated.
3 to a position where the motion can be transmitted, but since the pusher 61 rides on the other end of the door opening confirmation protrusion 32b, the frame body 64 is biased toward the micro switch 50 side, and the pusher 64 is moved to the side of the pushed protrusion 51. As described above, the pusher 61 does not reach the position where the motion can be transmitted until it is caught on the edge and separated from the door opening confirmation protrusion 32b.

The rotating body 30 rotates clockwise in FIG. 1 from the above state, and when it rotates to the fully closed state shown in FIG. 1, the pusher 61 rides on the protrusion 32a.
The pressed projection 51 of the micro switch 50 is pushed through the plunger 63 and the frame 64 to turn off the micro switch 50.

Accordingly, the power supply to the motor 22 is cut off and the motor 22 stops, and the lid body 12 enters the fully closed state shown in FIG. 4a.
Therefore, I let go of the operation switch and connected the energized wire 71.
When the power supply to 72 is stopped, the spring 65 pushes the plunger 63 and the clutch mechanism 60 pushes the plunger 63.
1 operation cannot be transmitted, and the circuit is unable to transmit the operation of 5th
The state returns to the state shown in the figure.

"Effect of the invention" According to the sunroof control device according to the invention,
Since stopping and reversing at a predetermined position of the operating stroke can be controlled with a single switch, the control device can be made thinner, smaller and lighter, and can be stored in a limited space. It can help provide a comfortable sunroof without impairing the livability of the vehicle interior.
