BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive motor control device for a sunroof for an automobile.

[0002]

2. Description of the Related Art Generally, in a sunroof for an automobile,
Under the control of the drive motor control device, a tilt control in which the rear end of the lid rises from the fully closed state and a slide control in which the lid slides rearward from the fully closed state are obtained.

[0003]

As described above, the drive motor control device for a sunroof for an automobile is capable of tilt control and slide control. These operations are performed by independently provided tilt operation switch and slide operation. It can be controlled by a switch. Further, a fully-closed position detection switch for tilt and a fully-closed position detection switch for sliding are provided to ensure that the lid stops at the fully closed position.

In this case, the fully closed position detecting switch for tilt is controlled on / off by a first cam surface, and the fully closed position detecting switch for sliding is controlled on / off by a second cam surface. In addition, uniform on-off accuracy is difficult to obtain from the point where the on / off operation is performed by separate cam surfaces, which is a factor that easily causes an accuracy error. In addition, it is not desirable in terms of assemblability using nerves for assembling.

In view of the foregoing, the present invention provides a drive motor control device for a sunroof for an automobile, in which the number of parts is reduced and the assembling work is facilitated, and the tilt control and the slide control can be performed. The purpose is.

[0006]

According to the present invention, in order to achieve the above object, current flows in a sunroof for an automobile which performs tilt control or slide control of a lid by forward / reverse rotation of a drive motor. A first and a second relay circuit that can be turned on and off at the same time, and a relay contact that opens and closes when the first and second relay circuits are turned on and off to rotate the drive motor forward and backward. A motor circuit, a first contact for turning on the first relay circuit from a neutral position, and a second contact for turning on the second relay circuit.
A switch circuit having an operation switch that can be switched to a contact, and a third relay circuit is turned on when a fully closed position of the lid is detected, and is turned off when a non-fully closed position is detected. And a detection switch circuit including a detection switch that holds the first or second relay circuit in an on state by operating the operation switch to the first or second contact. And a relay contact for holding the first or second relay circuit in an on state by operating the operation switch to the first or second contact when the switch is on.

[0007]

According to this drive motor control device, by switching the operation switch to the first contact or the second contact, the drive motor rotates forward or backward, and the tilt control and slide control of the lid can be performed. When the lid reaches the fully closed position during the tilt control or the slide control of the lid, the third relay circuit is turned on by the detection switch. Therefore, the drive motor is stopped by setting the operation switch to the neutral position. As a result, a fully closed state of the lid is obtained.

On the other hand, only one operation switch and one detection switch are required, and the number of components can be reduced.

[0032] In this state, the tilt-up, and operates the switch terminal 75a of the operation switch 75 to the first contact point P ₁ side, the relay coil R1 is an excited state of ON, the drive motor 7, as shown in FIG. 9 Is the first terminal 7
A current flows from the terminal a to the second terminal 7b, and the lid 1 rotates in the forward direction, and the tilted state of the lid 1 is obtained. When the tilt-up is completed, the switch terminal S1 of the detection switch LS- ₁ is set to the position shown in FIG.
Since switching replaces the grounding contact a _1, as shown in 0, the drive motor 7 relay coil R1 is turned off by returning to the neutral release the switch terminal 75a of the operation switch 75 is stopped.

Next, the tilting down from the state of the tilt-up, switches the switch terminal 75a of the operation switch 75 as shown in FIG. 11 to the second contact point P _2. Thereby, the relay coil R2 is excited. Accordingly, the drive motor 7 is reversed by the current flowing from the second terminal 7b to the first terminal 7a, and the lid 1 is lowered from the tilt-up state,
It reaches the fully closed state. Switch terminal S ₁ of the detection switch LS-1 as shown in FIG. 12 at the same time as the fully closed is restored to the contact a _2, the relay coil R ₂ drive motor 7 in a non-energized state is stopped.

As shown in FIG. 5, the switch terminal 75a of the operation switch 75
Switch the to the second contact P _2. As a result, the relay coil R2 is excited, and the drive motor 7 is connected to the first terminal 7b from the second terminal 7b.
The state is reversed by the current flowing through the terminal 7a, and a slide-open state in which the lid 1 is opened by a predetermined amount as shown in FIG. 6 is obtained. At this time, as shown in FIG.
Since -1 switch terminal S1 is Ru switched to earth contact a _1, the relay coil R ₂ is turned off the drive motor 7 by the switch terminal 75a to release the returns to the neutral is stopped.

[0035] Then, to the fully closed from the state of the slide open, switches the switch terminal 75a of the operation switch 75 as shown in FIG. 17 to the first contact point P _1. Thereby, the relay coil R1 is excited, and the drive motor 7 is normally rotated by the current flowing from the first terminal 7a to the second terminal 7b, so that the lid 1 can be fully closed.

The switch terminals S ₁ of the second detection switch LS-1 at the same time fully closed is restored to earth contacts P ₄ (FIG. 1
8). Further, the relay coil R ₁ Since the non-excited state, the driving motor 7 is stopped.

[0037]

As described above, according to the drive motor control device of the present invention, the operation switch and the detection switch can be omitted, so that the entire device can be simplified and the assembling work can be facilitated. . Also, since only one detection switch is required, the accuracy error can be minimized.
This is very favorable in terms of work steps and cost reduction.
