Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a sliding roof that is provided on the roof of an automobile so that it can be opened and closed, and more specifically, the sliding roof is configured such that the sliding roof can be opened by sliding above a fixed roof. This relates to a sliding roof device.

(Prior Art) Vehicles have been known in which a sliding roof that can be opened and closed is provided on the roof of an automobile to improve ventilation in the vehicle interior and to let in sunlight. The sliding roof can be opened and closed by moving the sliding roof below the fixed roof and moving it backwards, and by moving the sliding roof above the fixed roof and moving it backwards. There is. When the sliding roof is moved below the fixed roof, the sliding roof enters into the passenger compartment, which has the advantage that the air resistance during driving does not change much. Various models of this type have been proposed and put into practical use. There is. However, since the sliding roof enters into the vehicle interior, the interior space of the vehicle becomes narrow, which poses a problem in terms of comfort for the occupants.

For this reason, a type in which the sliding roof is moved upward has also been proposed. For example, in 1987
No. 33311 discloses a sliding roof provided on the roof of a passenger vehicle that is moved upward in parallel and then moved rearward to open it. In this way, when the slide roof is moved upward, the slide roof protrudes outside the vehicle, and the problem remains that air resistance increases during driving.

However, instead of moving the sliding roof in parallel upwards, there are some that attempt to obtain a spoiler effect using the sliding roof itself by having the rear end of the sliding roof rise higher than the front end. By creating a spoiler effect that improves tire grip and increases driving stability, the problem of increased air resistance due to the sliding roof is offset. Moving the sliding roof upwards does not put pressure on the interior space of the vehicle, which is preferable from the viewpoint of comfort, while moving the sliding roof downwards allows the sliding amount to be reduced due to the limited space within the vehicle interior. While limited,
When moving upward, there is no such restriction, so there is an advantage that the sliding amount can be increased and the opening area can be increased. However, in a car that has a hatchback door that covers the rear of the car body and opens and closes up and down, if the sliding roof is open when the back door is opened, the rear end of the sliding roof and the back door may interfere with each other. There is a problem.

(Object of the Invention) The present invention has been made in view of the above problem, and when the hatchback door is opened while the sliding roof is open, the sliding roof is moved forward by a certain amount by electric means, that is, in the closing direction. It is an object of the present invention to provide a sliding roof device for a motor vehicle that can be moved to a hatchback door and prevent interference between the sliding roof and a hatchback door.

(Structure of the Invention) The sliding roof device of the present invention is configured such that the sliding roof is slid on a fixed roof by a drive motor in response to the operation of an opening/closing switch, and whether or not the sliding roof is opened a predetermined distance or more is checked. A limit switch that detects whether the back door is opened or closed, and a back door switch that detects whether the back door is open or closed.When the sliding roof is opened a predetermined distance or more and the back door is detected to have been opened, the drive motor is activated to move the sliding roof in the direction of closing. The invention is characterized in that it has a control circuit that controls the operation.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 and FIG. 2 are both cross-sectional views of the roof portion of an automobile equipped with the sliding roof device of the present invention, and the left side of the drawings is the front of the vehicle. A front window glass 5 in front of a driver's seat is attached to the front of the vehicle body, and a back door 4 that covers the rear part is attached to the rear of the vehicle body so as to be openable and closable. The back door 4 can be opened and closed vertically (in the direction of arrow A) about its upper hinge portion 4b, and in this figure, a solid line 4 indicates a closed state, and a chain double-dashed line 4a indicates an open state.

The roof consists of a fixed roof 1 and a sliding roof 2 that covers an opening formed in the fixed roof 1.
The slide roof 2 is guided by a guide rail 3 fixed to the fixed roof 1 and is slid rearward by a drive motor (not shown) so as to overlap the fixed roof 1. At this time, the slide roof 2 is at the front end 2a.
The slide roof 2 is held so that it is lower than the rear end 2b, that is, lowered forward, so that the slide roof 2 exerts a spoiler effect when driving.

There is no problem in opening and closing the back door 4 when the sliding roof 2 is closed as shown in FIG. When opened, the rear end 2b of the slide roof 2 and the back door 4a interfere with each other. Therefore, when the back door 4 is opened, the drive motor is activated to move the slide roof 2 forward by a distance indicated by S in the figure. Detection of this moving distance S is performed by a limit switch 6 provided on the guide rail 3. In this way, interference between the slide roof 2 and the back door 4a is prevented. Note that when the back door 4a is subsequently closed, it is desirable to operate the drive motor again to move the slide roof 2 rearward and return it to its original state.

FIG. 3 shows an electric circuit for controlling the operation of the sliding roof device of the present invention. This circuit includes an opening/closing switch 10 operated by the occupant, a drive motor 52 that slides the sliding roof 2, a back door switch 54 that is turned on and off by opening and closing the back door 4, and a check whether the sliding roof 2 has moved a predetermined amount. It has the limit switch 6 shown in FIG. 2 for detection, the first and second relays 20, 30, and the capacitor 53, and by connecting these as shown in the figure, the sliding roof shown in FIGS. 2 movements can be performed. In addition, the back door switch 6 turns OFF when the back door is closed and turns ON when the back door is opened, and the limit switch 6
is ON when slide roof 2 is opened more than a specified amount.
At other times, it is OFF.

The operation will be explained below.

First, consider the case when both the slide roof 2 and the back door 4 are closed. At this time, both the limit switch 6 and the back door switch 54 are
It is OFF, and the solenoids 23 and 33 of the first relay 20 and the second relay 30 are not energized. Therefore, the switch bodies 21 and 22 of the first relay 20
are connected to terminals 21a and 22a, respectively, and switch bodies 31 and 32 of second relay 30 are connected to terminals 31a and 32a, respectively. Open/close switch 10
is in the OFF state unless operated, that is, the switch bodies 11 and 12 are connected to the terminals 11a and 1 as shown in the figure.
It is maintained in a state where it is not connected to either 2a or 13a. In this circuit, lines 56 and 57 are connected to the battery to receive power supply, and the on/off switch 10 and the first relay 2
0 cuts off the power supply to the drive motor 52.

Open/close switch 1 to open sliding roof 2
0 to the open side. In this figure, the switch bodies 11 and 12 of the open/close switch 10 (these switch bodies 11 and 12 only move in conjunction with each other) are tilted to the left in the figure, and the switch bodies 11 and 12 connect to the terminals 11a and 13a, respectively. The open side operation is to make the connection. Therefore, when the open/close switch 10 is operated to the open side, the power supply current from the line 56 is applied to the switch body 11 connected to the terminal 11a and the terminal 21a.
switch body 21 and fuse 51 connected to
The current is transmitted to the drive motor 52 through the drive motor 52, flows in the direction of arrow B, and then is grounded via the switch body 22 connected to the terminal 22a, the switch body 12 connected to the line 13a, and the line 13. Ru. Therefore, the drive motor 52 is driven and the slide roof 2 is opened.

When you release your hand from the open/close switch 10, the switch bodies 11 and 12 return to OFF, the power supply from the line 56 to the drive motor 52 is cut off, and the slide roof 2 stops at that point and can be opened to any desired degree. I can do it. Furthermore, when the open/close switch 10 is turned to the closed side, that is, the switch bodies 11 and 12 are turned to the right side, the power supply current from the line 56 is transmitted to the drive motor 52 via the switch body 12 and the switch body 22 connected to the terminal 12a. , after flowing in this drive motor in the direction of arrow C (opposite direction to the above), the switch body 21 and the switch body 1 connected to the terminal 13a.
Grounded via 1. In this way, the slide roof 2 can be opened and closed by operating the drive motor 52 by operating the opening/closing switch 10.

When the slide roof 2 opens more than a predetermined distance and hits the limit switch 6, the limit switch 6
is turned ON, and this ON state is the slide roof 2
is maintained as long as it is open by a predetermined distance or more. Note that this predetermined distance is the rear end 2b of the slide roof 2.
This is set close to the interference limit of the back door 4a when it is opened. That is, when the slide roof 2 is located in the range where the limit switch 6 is turned on, interference with the back door 4a will occur if the slide roof 2 is located in the range where the limit switch 6 is turned on.

Here, a case will be described in which the slide roof 2 is opened a predetermined distance or more and the limit switch 6 is in the ON state, and the back door is opened and the back door switch 54 is turned ON. back door switch 54
When turned ON, the solenoid 23 of the first relay 20
is excited, and the switch bodies 21 and 22 are connected to the terminals 21b and 22b, respectively. At the same time, since the limit switch 6 is ON, the solenoid 33 of the second relay 30 is also energized, and the switch bodies 31 and 32 are connected to the terminals 31b and 32b, respectively. Therefore, the power supply current from the line 56 is transmitted to the drive motor 52 via the back door switch 54, the limit switch 6, the switch body 32 connected to the terminal 32b, and the switch body 22 connected to the terminal 22b. After flowing in the direction of arrow C, it is grounded via the fuse 51, the switch body 21 connected to the terminal 21b, and the switch body 31 connected to the terminal 31b. Therefore, the drive motor 52 moves the slide roof 2 in the closing direction. When the slide roof 2 is moved in the closing direction and the opening degree becomes less than a predetermined distance, the limit switch 6 is turned off, the connection between the drive motor 52 and the power source is cut off, and the slide roof 2 is stopped. That is, the slide roof 2 is connected to the limit switch 6.
is moved in the closing direction until it turns OFF, and is held at the position moved by a distance S shown in FIG. Therefore, interference between the back door 4a and the rear end 2a of the slide roof 2 can be prevented.

Next, when the backdoor 4a is closed (set to position 4), the backdoor switch 54 is turned off again, the solenoid 33 of the second relay 30 is de-energized, and the switch bodies 31 and 32 are connected to the terminals 31 and 32 respectively.
Connect to a and 32a. However, the solenoid 23 of the first relay 20 is energized by the discharge of the capacitor 53 that has been charged by energization up to that point, and is kept in that state until the discharge is completed. Note that the diode 58 prevents the reverse flow of this discharge current so that only the solenoid 23 is energized. Therefore, the power supply current from the line 57 is transferred to the switch body 31 connected to the terminal 31a, and to the terminal 21b.
switch body 21 and fuse 51 connected to
is transmitted to the drive motor 52 via the drive motor 52
After flowing inside in the direction of arrow B, the switch body 22 is connected to the terminal 22b, and is connected to the terminal 32a and grounded via the switch body 32. By energizing the drive motor 52, the slide roof 2 can be opened again.

(Effects of the Invention) As explained above, according to the present invention, if the back door is opened when the sliding roof is open a predetermined distance or more, the sliding roof will be closed by a certain distance and interference between the two can be prevented. The opening area can be made sufficiently large.
