Description

[Detailed Description of the Invention] The present invention relates to a control device for an electric sliding roof of an automobile.

In automobiles, a sliding roof device is already known in which an opening is provided in the ceiling, a roof member that is slid back and forth along a guide rail or the like is provided in the opening, and the opening is opened and closed by the roof member. , as means for moving the roof member,
Generally, a structure is adopted in which the motor is driven by an electric device. At this time, when the roof member is closed, there is a risk that a hand or the like may be caught between the front edge of the opening and the front edge of the roof member due to the operator's carelessness, so the roof member is temporarily stopped at an appropriate moving position. There is also a method in which the valve is closed completely by other means. (For example, Japanese Utility Model Application Publication No. 55-56721) However, whether the roof member is closed by the two-stage operation or simply by one operation, it is often difficult to ensure that the roof member is closed. If the driver forgets to leave the vehicle and leaves the vehicle, there may be theft or other problems.

In view of this, the present invention automatically and reliably tightens the roof member when the driver forgets to tighten the roof member by removing the ignition key (hereinafter simply referred to as the key) from the key cylinder when the driver leaves the vehicle. The purpose is to block it.

Embodiments of the present invention will be described below with reference to the drawings.

An opening 3 is provided in front of the ceiling 2 of the vehicle body 1, and a sliding roof device 4 for opening and closing the opening 3 is provided. This slide roof device 4 includes a slide roof 5 that covers the opening 3, a drive motor 6 for sliding the slide roof 5 in the front and back direction along the opening 3, and a motor and a drive motor 6 for sliding the slide roof 5 in the front-rear direction along the opening 3. It is mainly composed of a connecting mechanism 7 for connecting the roof 5 and a guide rail (not shown) for guiding the sliding roof 5, and the sliding roof 5 closes the opening 3 by rotation of the motor 6 in one direction. The slide roof 5 is moved backward from the position to open the opening 3, and by reverse rotation of the motor 6, the slide roof 5 moves in the opposite direction to close the opening 3. It is selected as appropriate depending on the shape of the rail.

FIG. 3 shows a first embodiment of the operating circuit for the motor 6. The roof relay circuit 8 for switching the motor 6 between forward and reverse directions consists of an opening relay 9 and a closing relay 10. 10 is operated by operating an operating switch 11. The operating switch 11 includes a movable contact piece 11 that is operated from the outside.
a is the ground side, and both fixed contacts 11b, 11
It is maintained in a neutral state with respect to c. One fixed contact 11b, which together with the movable contact 11a constitutes a closing side operating switch, is connected to the positive terminal of the power source 12 via the relay coil 10a of the closing relay 10 to form a closing circuit 13, and the movable contact 11a
Together with this, it constitutes an opening operation switch. The other fixed terminal 11c is similarly connected to the positive terminal of the power source 12 via the relay coil 9a of the opening relay 9 to form an opening circuit 14.

Relay contacts 9b and 10b of the opening relay 9 and closing relay 10 are provided in the drive circuit 15 of the motor 6, and the movable contact piece 9c of the relay contact 9b is located on one terminal 6a side of the motor 6. The movable contacts 10c of the relay contact 10b are connected to the other terminal 6b of the motor 6, and both movable contacts are always connected to the ground terminals 9d and 10d, and when activated, they are connected to the power supply terminals 9e and 10e. Can be switched.

As a result, when the operation switch 11 is turned on, for example, with the fixed contact 11b side turned on and the closing circuit 13 is closed, the closing relay 10 is activated, and the movable contact piece 10c of the relay contact 10b is connected to the power supply side terminal. 1
0e side, a charge is applied to the motor 6 from the terminal 6b toward the terminal 6a, and the motor 6 rotates in the direction to close the slide roof 5.
The movable contact piece 11a of the operation switch 11 is connected to the fixed contact 1
1c side, the opening circuit 14 side is closed, the opening relay 9 is activated, the relay contact 9b is switched and an electric charge is applied to the motor 6 in the opposite direction to the above, and the motor 6 is connected to the sliding roof 5. Rotate in the direction of opening.

In addition to closing the closing circuit 13 using the operation switch 11, the closing circuit 13 can also be closed by the driver using a key cylinder (not shown).
The closing relay 10 is closed for a predetermined period of time by a key detection switch that turns on when the key is removed.
It is made to operate. In other words, the closing circuit 13 includes a key detection switch 21 that is turned on when the key is removed, and a timer 22 that is connected to the key detection switch 21 and determines the energization time of the key detection switch 21. An automatic closing circuit 20 is connected thereto.
The timer 22 is, for example, a key detection switch 21.
When the switch is turned on, operation is started by a pulse signal applied from the power supply 12, and the main circuit contact 22a is closed.
It is preferable to have a structure in which the circuit contact 22a is opened after a predetermined time has elapsed, and the operating time is set to the time required for the slide roof 5 to be completely closed from the fully open position. Incidentally, a slip mechanism is usually provided in the linkage mechanism between the motor and the slide roof, so that there is no problem even if the key detection switch 21 is closed while the slide roof is half open.

FIG. 4 shows another example of the automatic closing circuit, in which an automatic closing circuit 25 connected to the closing circuit 13 is shown.
In this example, a time relay 27 activated by the closing of the key detection switch 26, similar to the previous example, is used to close the switch for a predetermined period of time, and the activation circuit 28 is connected in series with the time relay 27 of the key detection switch 26. The automatic closing circuit 25 is provided with a normally open contact 27a of a time relay 27. When the key is removed, the key detection switch 26 is turned on, the time relay 27 starts operating, and the contact 27a is closed, thereby closing the closing circuit 13. The set time of the time relay 27 is the same as in the previous example.

In both of the above embodiments, the motor 6 is rotated in forward and reverse directions by manual operation of the operating switch 11 to open and close the slide roof. Also, if the driver leaves the car with the sliding roof 5 open,
Since the key is removed from the key cylinder, the key detection switches 21 and 26 are turned on. Therefore,
The motor 6 automatically operates to close the sliding roof 5.

Since the present invention has the above structure, even if the driver forgets to tighten the sliding roof, the sliding roof will be automatically closed when the driver removes the ignition key from the key cylinder. accidents can be prevented.
