Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a drive motor control device for a vehicle sunroof.

(Prior Art) Conventionally, an opening / closing body of a vehicle sunroof can perform a slide control in which it is slid back and forth by the power of a drive motor and a tilt control in which a rear end side moves up and down. The drive motor for driving the opening / closing body is controlled by on / off signals from a slide detection switch and a tilt detection switch as described in JP-A-63-199121. That is, as shown in FIGS. 12 and 13, the switch terminals 105 and 107 of the tilt and slide detection switches 101 and 103 are formed on the peripheral surface of the rotating body 111 having the rotating gear 109 driven by the drive motor. The slide control surface 113 and the tilt control surface 115 are in contact with each other, and are turned on / off by the control surfaces 113 and 115.

(Problems to be Solved by the Invention) As described above, the slide control surface 113 and the tilt control surface 115 for turning on and off the detection switches 101 and 103 are the rotating body 111.
Within one rotation, a is a slide area and b is a tilt area. For this reason, the size of the slide area a is limited by the size of the tilt area b, and when the slide amount of the opening / closing body is increased due to a design change or the like, the following inconvenience may occur. become.

That is, if the number of teeth of the rotary gear 109 provided on the rotary body 111 is increased in proportion to the sliding amount, the diameter is also increased, the shape of the entire drive unit is increased, and downsizing cannot be achieved.

Also, if the gear module of the rotary gear 109 is made smaller,
This leads to a total change of each gear train of the transmission system, which requires a great cost review of the production facility and is not desirable in terms of strength.

Has become.

FIG. 9 shows a control circuit. In this control circuit, TL is a tilt operation switch having a descending contact t ₁ and an ascending contact t ₂ , and SL is a slide having a fully open contact o ₁ and a fully closed contact o ₂ . Each operation switch is shown. In each of the tilt and slide operation switches TL and SL, the switch terminal t of the tilt operation switch TL can be switched from the neutral position to the descending contact t ₁ and the ascending contact t ₂ . In addition, the switch terminal O of the slide operation switch SL
In this case, from the neutral position to the fully open contact o ₁ and the fully closed contact
o ₂ and can be switched.

Lowering contact t ₁ of the tilt manipulation switch TL is connected to the second detection switch LS-2 open contact NO, increased contact t ₂ is connected to the first detection switch LS-1 open contact NO. The fully open contact o ₁ of the slide operation switch SL is connected to the closed contact NC of the second detection switch LS-2 and is a fully closed contact.
o ₂ is connected to the close contact NC of the first detection switch LS-1.

In addition, a power supply circuit B such as a battery via a switch terminal S ₂ of the second detection switch LS-2 and a second relay coil R ₂ ,
Further, the switch terminal S ₁ of the first detection switch LS-1 is connected to the power supply circuit B via the first relay coil R ₁ respectively, and when the opening / closing body 1 is in the fully closed state, each of the closed contacts.
Located in NC and NC respectively. Furthermore, FIG. 9 (b)
As shown in FIG. 5, the slide control start end face 58a and the tilt control start end face 65a formed in a V shape as viewed from above are faced.

The first and second relay coils R ₁ and R ₂ have the first relay terminal r-1 and the second relay provided in the motor circuit M of the drive motor 7 when the current flows through the coils R ₁ and R _2. It functions to switch the terminal r-2 from the ground contact o ₂ to the open contact a ₁ .

Next, the operation will be described. When the opening / closing body 1 is fully closed, the switch terminals S ₁ and S ₂ of the first and second detection switches LS-1 and LS- ₂ are the slide control start end faces as shown in (a) and (b) of FIG. 58a and the tilt control start end face 65a are in contact with each other, the contact is located on the close contact NC side, and the first and second relay terminals r-1 and
r-2 is located at ground contact a ₂ .

Next, in order to tilt up the opening / closing body 1, as shown in FIG. 11, the switch terminal t of the tilting operation switch TL is switched to the rising contact t ₂ side. As a result, the first relay coil R ₁
Is excited and the first relay terminal r-1 switches from the ground contact a ₂ to the open contact a ₁ , the drive motor 7 rotates, and the opening / closing body 1
The switch terminal t is returned to neutral because the tilt-up state of 1 can be obtained. At the same time, the switch terminal S ₂ of the second detection switch LS- ₂ is switched to the open contact NO by the tilt control surface 65. Next, in order to fully open the opening / closing body 1 in the tilt-up state, the tilt operation switch is used.
When the switch terminal t of TL is changed from neutral to the descending contact t ₁ , the first relay coil R ₁ is deenergized, the second relay coil R 2 is excited, and the first relay terminal r-1 is an open contact.
Switch to a ₁ . As a result, the drive motor 7 is rotated in the reverse direction to obtain the fully closed state of the opening / closing body 1, and the tilt control of the opening / closing body 1 can be performed by operating the tilt operation switch TL.

Next, in order to fully open the opening / closing body 1 when fully closed, the switch terminal O of the slide operation switch SL is switched to the fully open contact o ₁ side as shown in FIG.

At this time, the second relay coil R2 becomes excited state, the second relay terminal r-2 switching instead drive motor 7 in an open contact a ₁ is rotated. At the same time, the first and second rotating bodies 56, 63 also rotate, and the slide control surface 58 switches the switch terminal S ₁ of the first detection switch LS-1 to the open contact NO.

Then, during the rotation of the first and second rotating bodies 56, 63, the switch terminal S ₂ of the second detection switch LS- ₂ comes into contact with the locking step surface 67 of the locking portion 66 as shown in (c). While the second rotating body 63 stops, the switch terminal S _{1 of the} first detection switch LS- ₁
Since the ON state is held by the holding surface 68 as shown in FIG. 3, only the first rotating body 56 continues to rotate until the sliding opening of the opening / closing body 1 is completed. As a result, as shown in FIG. 1, the slide area X is expanded by the area y, and the opening / closing body 1 is fully opened. When the full opening is completed, the switch terminal O is returned to neutral.

Next, from full open to full close, slide operation switch
When the SL switch terminal O is operated from neutral to the fully closed contact o ₂ side, the first relay coil R ₁ is in the excited state, while the second relay coil R ₂ is in the non-excited state, so the first relay terminal r -1 switches to the open contact a ₁ and the second relay terminal r-2 switches to the ground contact a ₂ . As a result, the opening / closing body 1 slides due to the reverse rotation of the drive motor 7, and the switch terminals S ₁ and S _{2 of} the first and first detection switches LS-1 and LS-2 face the control start end surfaces 58a and 65a. It is turned off at the same time, and the opening and closing body 1
Stops at the fully closed position, and the fully closed state of the roof opening 3 is obtained.

Although the switch terminal S ₂ of the second detection switch LS-2 is used as a stopper in this embodiment, a stopper capable of advancing and retreating may be separately provided.

[Effect of the Invention] As described above, according to the drive motor control device of the present invention, the first detection switch for slide control is turned on by the locking portion provided on the tilt control surface of the second rotating body. Since it can be held, the slide area can be enlarged without increasing the size of the device.
