Description

TECHNICAL FIELD The present invention relates to a sunroof drive motor control circuit.

[Prior Art] Conventionally, a tilt control for raising and lowering a rear end of a lid provided in a roof opening is performed for tilting up and down, and an opening / closing body such as a lid is slid back and forth to fully open and close the roof opening. The slide control for achieving this is performed by the drive motor.

[Problems to be Solved by the Invention] As described above, the drive motor for driving the opening / closing body is, for example,
Tilt control is possible by rotating the open / close body forward when it is tilted up and reversely rotated when it is tilted down. After closing, the operation switch for slide opening was subsequently operated, and the switch operation was required twice, which was not preferable in terms of operability. For this purpose, for example, Japanese Patent Laid-Open No.
As disclosed in Japanese Patent Laid-Open No. 1-92922, there is a means in which, for example, after the lid is fully closed at the time of tilting up, the slide opening can be performed by continuing to operate the closing switch.

This means requires the switch operation to be continued from the tilt-up time to the fully closed state and from the fully closed state to the slide-opened state, which requires a long operation time. For this reason, when the vehicle is running, the switch operation is performed in parallel with the driving operation, so that the eyes are separated from the forward field of view, which is not desirable in terms of safe driving.

Therefore, the present invention provides a drive motor control circuit for a sunroof which improves the operability and ensures safe driving by enabling the opening / closing body to continue the operation in both the tilt stroke and the slide stroke by one-touch switch operation. Is intended.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the present invention provides a drive motor for driving an opening / closing body provided in a roof opening by a forward rotation and a reverse rotation so as to freely slide and tilt, and a tilt operation switch. In a drive motor control circuit comprising a tilt control circuit for rotating the drive motor forward or reverse by switching a switch terminal, and a slide control circuit for rotating the drive motor forward or reverse by switching a switch terminal of a slide operation switch, It has a contact to rotate the drive motor by one-touch operation, and disconnects when the tilt-up is completed and the slide-open is completed, and has an automatic contact that can be disconnected / contacted to stop the rotation of the drive motor, and the tilt-up opening / closing body is slid open. Tilt the opening / closing body when the slide is open until the completion. An auto control circuit is provided to keep the drive motor rotating by making contact with the auto contact until the completion of up.

[Operation] In the drive motor control circuit, the drive motor is normally or reversely rotated by the switch operation of the tilt operation switch, so that the tilt-up state and the fully-closed state of the opening / closing body can be obtained. Further, the drive motor is normally or reversely rotated by the switch operation of the slide operation switch, so that the open / close state of the opening / closing body can be obtained.

Next, when the opening / closing body is tilted up or slid open, the automatic control circuit operates when the auto contacts are brought into contact with each other by one-touch operation, and the rotation of the drive motor is continued until the opening / closing body is slid open or tilted up. The operation at this time is simple because it can be done with one touch, so that it does not affect the driving operation even while traveling, and safe driving is ensured.

When the relay terminals r ₁ and r ₂ are opened, they are grounded to the vehicle body and the drive motor 7 stops braking.

Next, the operation will be described. First, in order to tilt up the opening / closing body 1 in the fully closed state, as shown in FIG. 6, first, the tilt up switch TL-1 is opened and the open contact NO.
Operate to the side. Thus the second relay coil R ₂ is excited drive motor 7 reverses current flows through the first motor terminal 7a of the second motor terminal 7b. As a result, the rear end of the opening / closing body 1 rises upward from the roof opening 3. At the end of the raising of the opening / closing body 1, the power transmission is continued, but the friction clutch plate 27 slips, and the tilt-up state is obtained without applying an undue load to the drive motor 7. If the switch operation is released after the tilt-up is confirmed, the second relay coil R ₂ is deenergized due to the release of the switch operation. Therefore, the relay contact r ₂ returns to the open contact a ₂ and the motor 7 stops braking. As a result, the tilt-up state of the opening / closing body 1 can be obtained.

Next, in order to fully close the opening / closing body 1 in the tilt-up state, the first relay coil R ₁ is excited and driven by closing the open contact of the tilt-down switch TL-2 as shown in FIG. The motor 7 has a second motor terminal 7a through a second motor terminal 7a.
Electric current flows through the motor terminal 7b to rotate in the normal direction. When the opening / closing body 1 is lowered and fully closed, the switch terminal S ₁ of the first detection switch LS- ₁ is turned on by the rotation of the first control surface 63, and is switched to the open contact NO. As a result, the first relay coil R1 is deenergized and the drive motor 7 is braked. As a result, the roof opening 3 can be fully closed by the opening / closing body 1, and the respective switches TL-1 and TL-2 can be obtained.
The tilt control of the opening / closing body 1 can be performed by the operation.

Next, in order to fully open from the fully closed state, the first slide operation switch SR-1 is opened as shown in FIG.
Operate one step to the side. At this time, the first detection switch LS-
Since the switch terminal S ₁ of No. ₁ is switched to the open contact NO side by the first control surface 63, the first relay coil R ₁ is in the excited state and the drive motor 7 has the first
A current flows from the motor terminal 7a to the second motor terminal 7b to rotate in the normal direction. When the opening / closing body 1 is slid backward to be fully closed, the switch terminal S ₁ of the first detection switch LS- ₁ is normally closed by the first control surface 63.
Return to C side. As a result, the first relay coil R ₁ is de-energized and the drive motor 7 is braked. As a result, the opening / closing body 1 is housed in the roof 9 and the roof opening 3 is fully opened.

Next, in order to change from fully open to fully closed, the first slide operation switch SR-2 is opened as shown in FIG.
Switch to side. As a result, the second relay coil R2 is excited to drive the drive motor 7 from the second motor terminal 7b to the first
A current flows through the motor terminal 7a and reverses. As a result, the opening / closing body 1 slides forward, but about 15 degrees at the fully closed position.
The third control surface 67 is the third detection switch LS before 0 mm.
The switch terminal S ₃ of -3 to switching control normally closed contacts NC becomes open. As a result, the excitation of the second relay coil R ₂ is released and the drive motor 7 is stopped by the brake. As a result, the opening / closing body 1 temporarily stops about 150 mm before fully closing. At this time, the second slide operation switch SR
The drive motor 7 is maintained in the stopped state even if -2 is continuously operated.

Next, one sputum second slide operation switch SR-2 to release the operation when the first closing switch terminal SC ₂ is returned to the closed contact NC side. At the same time, the switch terminal S ₃ of the third detection switch LS-3 switches to the open contact NO, so that when the second relay coil R ₂ is re-excited by the current flowing through the third detection switch LS-3. , The third control surface 67 is moved by the drive motor 7, and switches the switch terminal S ₃ of the third detection switch LS-3 from the normally closed contact NC to the open contact NO.
Next, when the first close switch terminal SC ₂ is switched to the open contact NO again, the second relay coil R2 is excited and a current flows from the second motor terminal 7b to the first motor terminal 7a in the drive motor 7 to reverse the rotation. . Then, when the opening / closing body 1 reaches the fully closed position, the switch terminal S ₂ of the second detection switch LS-2 pressed by the second control surface 65 returns to the normally closed contact NC side, so that the opening / closing body 1 is opened. Stops at the fully closed position and the fully closed state of the roof opening 3 is obtained (Fig. 24).

Hereinafter, the first and second slide operation switches SR-1 and S
By operating R-2, it is possible to fully open / close the open / close body 1.

Next, when the opening / closing body 1 is tilted up, as shown in FIG. 16, the first slide operation switch SR-1 is pushed in two steps to switch the first slide switch terminal SC ₁ to the automatic contact A ₁ . The operation at this time is a one-touch operation and does not significantly affect the driving operation even while traveling.

On the other hand, the contact of the auto contact A ₁ excites the _first and third relay coils R ₁ and R ₃ , and the second relay first terminal r ₃ is closed to operate the self-holding circuit GH. As a result, even if the first slide switch terminal SC ₁ returns from the auto contact A ₁ to the normally closed contact NC, the excited state is ensured in the first relay coil R ₁ by the current flowing through the self-holding circuit GH, and the drive is performed. In the motor 7, current flows from the first motor terminal 7a to the second motor terminal 7b, and normal rotation is continued. When the opening / closing body 1 has passed the tilt stroke and entered the slide stroke to reach the fully open position, the first detection switch LS-
The switch terminal S ₁ of ₁ is a normally closed contact NC,
In addition, the switch terminal S _{2 of the} second detection switch LS- ₂
Are switched to open contacts NO, the fourth relay coil R ₄ is excited, and the fourth relay terminal r ₄ is opened. As a result, the opening / closing body 1 stops at the fully open position and the fully opened state of the roof opening 3 is obtained, and the opening / closing body 1 at the time of tilting up can be moved to the slide open position by one-touch operation.

Although the automatic control circuit of this embodiment has been described so that the opening / closing body 1 can be operated from the time of tilting up to the slide opening, the opening / closing body 1 in the slide opening can be operated up to tilting up. Is also possible.

Further, the automatic contact A ₁ is brought into contact with it by using a two-step push of the first slide operation switch SR-2, but the contact is made by a one-touch operation button provided separately. May be.

[Advantages of the Invention] As described above, according to the drive motor control circuit for a sunroof of the present invention, a one-touch operation for making contact with an auto contact can, for example, operate a lid at the time of tilting up to a slide open position at once. Therefore, the operability can be improved, and moreover, since the operation can be done with one touch, it is possible to concentrate on the driving even while traveling, which is very preferable from the viewpoint of safe driving.
