Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a drive device for a vehicle cover roof.

[Prior Art] Conventionally, in sunroofs for automobiles, etc., a driving device for an opening/closing body that opens and closes the lean roof includes a drive motor and a first transmission system that transmits the rotational power of the drive motor to a drive cable of the opening/closing body. and a second transmission system that transmits power to the rotating body, which has a control surface that turns on and off a detection switch for detecting the open/close position of the opening/closing body.

The rotating body driven by the second transmission system is provided on the drive axis 1- driven by the drive motor and is placed close to the control surface of the rotating body, as shown in, for example, Japanese Patent Application Laid-Open No. 58-214414. The structure consists of multiple detection switches. [Problems to be solved by the invention (1) As mentioned above, since the rotating body is provided on the drive axis, the detection switches that are turned on and off by the rotating body and the control surface of the rotating body protrude upward from the case. Therefore, the height to the rotating body, that is, the thickness of the entire device may increase. In particular, since the drive device is placed within the storage space of the outer and inner panels of the roof, it is desirable to keep it as compact as possible, but as mentioned above, as the overall thickness of the device increases, the storage space will need to be taken up accordingly. A large space must be provided, which causes the problem of lowering the ceiling inside the vehicle.

For this purpose, for example, a transmission gear for taking out power is separately provided in the first transmission gear system that transmits to the drive cable of the opening/closing body, and the transmission gear A7 is connected to the first transmission gear of the second transmission gear to system 7. A conceivable method is to engage the transmission gear 17 to extract the power. This makes it possible to reduce j7 on the drive axis, but
Since the structure is such that the transmission gear A7 for extraction is provided below the first transmission gear system, the thickness of the transmission gear area increases.

The region of this transmission gear A7 is crossed by the drainage gutter in the vehicle width direction, and is a place where the thickness is restricted, so it is not suitable for structural retaining to provide a separate transmission gear, and as mentioned above, the height of the large moon in the vehicle interior is limited. cause problems that affect the

On the other hand, a plurality of detection switches, such as those for sliding and tilting, whose switch terminals contact the control surface of the rotating body, are arranged along the periphery of the rotating body. In this case, it is necessary to position each detection switch at a position that correctly detects the open/closed position of the opening/closing body, so each detection switch must be installed one by one by aligning it to the set location, so it takes care to install it. This is not desirable in terms of ease of assembly, and errors tend to occur during assembly.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a vehicle sunroof drive device that can be made thinner, and the detection accuracy and assembly of the detection switch can be improved.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a rotatable drive gear driven by power from a drive motor on the main shaft supported at both ends by the case body. At the same time, power is transmitted to the first transmission gear A7 series leading gear that transmits power to the drive section of the openable body, and a rotating body equipped with a control surface that turns on and off the detection switch for detecting the position of the openable body. The leading gear V of the second transmission gear system, which transmits the power, is meshed with the drive gear A7. In a preferred embodiment, a plurality of detection switches are provided close to the control surface of the rotary body, and the switch bodies of the detection switches are stacked in multiple stages on the same axis and attached to the case body.

[Function] In the drive device for the above-mentioned roof, power from the drive motor is input to the drive gear, and from the drive gear, one side is transmitted to the drive section of the closed body via the first transmission gear V system. communicated. On the other hand, power is transmitted to the rotating body via the second transmission gear system. In this case, since the first and second gears are branched from the drive gear, the thickness of the entire device can be kept small.

Further, the detection switch is turned on and off by the control surface of the rotating body, and the open/close position of the opening/closing body is detected. At the time of this detection, the switch body of the detection switch has an integral structure with multiple layers stacked on the same axis, so it is difficult to misplace and can perform highly accurate detection. This improves work efficiency as it only takes a few times.

Note that the self-holding circuit GH is the slide oven switch 5.
When the switch terminal SC2 of R-2 is switched to the oven terminal No side, the current flowing through the third relay coil R3 is stopped and the self-holding is released.

Next, the operation will be explained. To tilt up the opening/closing body 1 which is in the fully open state, first, as shown in FIG.
Operate to the o side. As a result, the second relay coil R2 is energized, and current flows through the drive motor 7 from the second motor terminal 7b to the first motor terminal 7a, causing the drive motor 7 to rotate in reverse. At the same time, due to the rotation of the first control surface 63, the normally closed contact NC of the switch terminal S1 of the first detection switch LS-1 becomes open, and the second relay coil R2 becomes de-energized.

Therefore, the relay contact r2 returns to the open contact a2, and the motor 7 is braked to a stop. As a result, a tilted-up state of the opening/closing body 1 can be obtained.

Next, in order to fully open the opening/closing body 1 in the tilted up state by 1 degree, as shown in FIG.
- By closing the oven contact of i, the first relay coil R1 is energized and the drive motor 7 is connected to the first motor terminal 7a.
A current flows from the motor to the second motor terminal 7b, causing forward rotation. At the same time, the opening/closing body 1 is lowered and the second control surface 65 is rotated to switch the switch terminal S2 of the second detection switch LS-2 to the oven contact NO. As a result, the first relay coil R1 is de-energized and the drive motor 7 is braked to a stop. As a result, the opening/closing body 1 reduces the total number of wings in the roof opening 3 to 1! Each switch TL-1.
By operating TL-2, the opening/closing body 1 is controlled by i1.
Becomes No.1.

Next, to listen from the fully open state, switch the slide oven switch 5R-2 to the A-bun contact NO side as shown in FIG. At this time, the second detection switch L S
-2 switch terminal S2 is in the state switched to the oven contact No side by the second control surface 65, so the first
The relay coil R1 is in an excited state, and current flows from the first motor terminal 7a to the second motor terminal 7b of the drive motor 7, causing it to rotate normally. At the same time, the opening/closing body 1 slides in the longitudinal direction, and when the second control surface 65 further rotates beyond the allowance area β, the switch terminal S2 of the second detection switch LS-2 returns to the normally closed contact NC side. As a result, the first relay coil R1 is de-energized and the drive motor 7 is brought to a brake stop.

As a result, the opening/closing body 1 is accommodated within the roof 9, and the roof opening 3 is fully opened.

Next, in order to fully close from fully open, the slide close switch 5R-1 is switched to the oven contact No. side as shown in FIG. As a result, the second relay coil R2 is energized, and current flows through the drive motor 7 from the second motor terminal 7b to the first motor terminal 7a, causing the drive motor 7 to rotate in reverse. At the same time, the opening/closing body 1 slides forward, but when it approaches the fully open position, the third control surface 67 contacts the switch terminal S of the third detection switch LS-3.
3 is switched and the normally closed contact NG becomes open. As a result, the second relay coil R2 is de-energized and the drive motor 7 is braked to a stop.

As a result, the opening/closing body 1 stops at Qf approximately 150,111 meters before the fully opened state. At this time, slide close switch 5R
Even if -1 is continued to be operated as it is, the drive motor 7 is maintained in a stopped state.

Next, the switch terminal SG+, which releases the operation of the -tan slide close switch 5R-1, returns to the close contact NG side, current flows through the self-holding circuit GH, and excites the third relay coil R3. In this case, two relay contacts r
3-1 and r3-2 are closed, and the self-holding circuit GH is secured. Therefore, as shown in FIG. 16', the slide close switch 5R-1 is again turned to
When operated to the side, the second relay coil R2 is energized through a circuit passing through the relay contact r3-2, and current flows from the second Tanabata terminal 7b to the first motor terminal 7a of the drive motor 97, causing the drive motor 97 to reverse rotation. Then, when the opening/closing body 1 comes to the fully closed position, the first detection switch L pressed against the first control surface 63
The switch gHH terminal 81 of S-1 returns to the normally closed contact NC side. .

In addition, the switch terminal S3 of the third detection switch LS-3
Since the normally closed contact NG/\ returns, the self-holding is released and the drive motor 7 is braked to a stop.

As a result, the opening body 1 stops at the fully closed position, and the roof opening 3 becomes fully open.

Thereafter, by operating the slide close switch 5R-1 and the slide oven switch S-2, the open body 1 can be fully closed or fully opened. When the opening/closing body 1 operates, the rotating body! Each detection switch 1-S-1, LS-2, LSL3 for each of the five control surfaces 63, 65, 67
Since it has an integrated structure stacked in multiple stages, there is no risk of positional deviation, and position detection is performed reliably.

In addition, the rotating body 59 and each detection switch 18-1/LS-
2. LS-3 no longer protrudes upward significantly,
The thickness of the entire device can be kept small.

[Effects of the Invention] As explained above, according to the υ roof drive device of the invention, since the rotating body that controls the detection switch is driven by the second transmission gear system branched from the drive gear 7, the drainage This eliminates any influence on the gutter area and allows the thickness of the entire device to be reduced, allowing the device to be easily removed without enlarging the storage space. In addition, each detection switch is stacked in multiple stages and attached to the case body, making it possible to obtain high detection accuracy.Furthermore, the installation and alignment can be done only once, improving work efficiency. .
