In order to obtain a comfortable habitability, for example, as disclosed in Japanese Utility Model Laid-Open No. 59-117522, a passenger car in which an opening formed in a vehicle body roof is covered with an openable / closable sunroof has attracted attention. In the case where this sunroof is of an electric slide type, for example, a sunroof movably arranged on guide rails arranged on both sides of an opening is moved forward and backward by a motor by a wire connected to the sunroof. By
It is opened and closed. When opening, the rear end of the sunroof is tilted up by the link mechanism and then slid backward. At the time of closing, after sliding the sunroof forward, the rear end is tilted down to be flush with the roof and closed.

[Problems to be Solved by the Invention] In the structure as described above, the drive source for tilting up, tilting down, and sliding the sunroof is usually a single motor, and its output is constant. The operation and the sliding operation are performed at the same rotation speed of the motor.

By the way, the rotational speed of the motor is set to be slightly higher because of the necessity of speeding up the sliding operation. Therefore, especially when the rear end of the sunroof is tilted down to close the opening, a loud tapping noise may be generated if the peripheral edge of the sunroof hits the inner peripheral edge of the opening, or the closing operation is smooth. There may be unexpected harm due to lack of.

The present invention has been made in consideration of such circumstances.
An object of the present invention is to provide a sunroof operation control device in which the opening / closing operation is smooth and, in particular, the generation of a tapping sound at the time of closing is avoided.

Further, wires 13, 13 each having one end attached to both sides of the transparent sliding roof 4 and having a spiral projection are engaged with each other to move the transparent sliding roof 4 back and forth. An intermittent drive gear 23 is attached to the other end of the gear shaft 22a for detecting whether the transparent sliding roof 4 is in a position state in which a tilt or slide operation should be started.

The detection means 6 is composed of the intermittent drive gear 23 having a single tooth tip forming the intermittent gear device, the driven gear 24, and a limit switch 25 provided near the driven gear 24. The driven gear 24 has an intermittent drive gear 23 in a part thereof.
A tooth tip 24a that meshes with a cam 24A is formed on another portion, and a lever 25a with a roller of a limit switch 25 is biased to the cam 24A. Therefore,
The position at which the transparent sliding roof 4 should start tilting or sliding by the operation of the lever 25a with a roller biased by the cam 24A that rotates according to the movement distance of the wire 13 attached to the transparent sliding roof 4. The state is detected. When the transparent sliding roof 4 is in the position for starting the tilting motion, the roller lever 25a is fitted into the cam groove 24b to give an ON signal, and when it is in the position for starting the sliding motion, the lever with roller is located. 25a is cam mountain 24
The OFF signal is input to the control means 7 in contact with c.

The control means 7 is composed of a solenoid 7a, a lever switch 7b that swings due to its excitation, a HIGH contact 7c that contacts the solenoid switch 7b and sets the drive speed of the electric motor 11 to a high speed, and a LOW contact 7d that sets it to a low speed. . The lever switch 7b is biased by a spring (not shown) so as to come into contact with the HIGH contact 7c in the free state. And, for example, the transparent sliding roof 4
Is detected by the detection means 6 when the lever 25a with the roller is fitted into the cam groove 24b of the driven gear 24, the ON state is reached as shown in FIG. The signal is input to the control means 7. Then, the solenoid 7a is excited, and the exciting force causes the lever switch 7b to resist the spring force and the LOW contact 7d.
Is adjusted so that the electric motor 11 rotates at a low speed.

The operation control device for the sunroof configured as above is
It works as follows.

In the initial state in which the electric motor 11 pulls in the wire 13 to the full extent, as shown in FIG. 3, the lower end of the link 12d is drawn to the front end of the window 12c, and the opening / closing operation member 12 is also pulled.

The front portion of the sunshade panel 9 is supported by being fitted into the lower rail 8 of the pin 9a, and the rear portion of the sunshade panel 9 is engaged with the locking member 14a projecting from the operating member 14 that is integrally mounted. It is supported by engagement with the groove 15. Only the sunshade panel 9 is manually engaged with the engaging groove 1 while being supported in the lower chamber of the transparent sliding roof 4 in parallel therewith.
It can also be retracted by a length of 5.

In order to tilt the transparent sliding roof 4 from this initial state, an operation switch (not shown) may be opened. First, the detection means 6 detects that the transparent sliding roof 4 is in a position state where tilting should be started, and an ON signal is input to the control means 7. Then,
As described above, the solenoid 7a is excited, the exciting force causes the lever switch 7b to be attracted against the spring force, the LOW contact 7d is closed, and the electric motor 11 constituting the drive means 5 is driven in the normal direction at a low speed. , The wire 13 is slightly extended. Thereby, first, the sliding member 12a remains stopped, the wire 13 is slightly retracted, and the lower end of the link 12d moves to the rear part of the window 12c. Therefore, link 12d
Rises and the transparent sliding roof 4 has a shaft 12b
The rear part slowly tilts up around, and the engaging pin 16 comes into contact with the lower surface of the lower tilt cam 14b. At this time, the sunshade panel 9 is lifted while the locking member 14a is still engaged with the engagement groove 15, and is rotated about the pin 9a, and similarly the rear portion is slowly tilted up (not shown). When the vehicle runs in this state, the air pressure in the vehicle is guided by the tilted up sunshade panel 9 due to the wind pressure associated with the running, and is led out of the vehicle from the rear of the sunshade panel 9 to perform ventilation in the vehicle room. With this tilt-up operation, the link 12d is raised, the engaging pin 6 is brought into contact with the tilt cam 14b, or

As described above, the low speed rotation of the electric motor 11 causes the electric motor 11 to rotate slowly so that generation of abnormal noise or vibration is avoided.

Then, when the opening operation of the operation switch is further continued, the cam 24A is rotated, the lever 25a with the roller is disengaged from the cam groove 24b, and is moved to the cam crest 24c, so that the sliding roof 4 should start sliding. Is detected and the OFF signal is input to the control means 7. Then, the solenoid 7a is demagnetized, the lever switch 7b swings by the biasing force of the spring, and the HIGH contact 7
c is closed, the electric motor 11 starts to drive at a high speed, the wire 13 is paid out a little more rapidly, and the sliding member 12a and the engaging pin 16 are united with the wire 13 and slide a little rearward. At the same time, the transparent sliding roof 4 also moves backward. Therefore, the locking member 14a is engaged with the engagement groove 1
5 Although the operating member 14 falls off from the front end, the retracted engagement pin 16 fits into the depth of the tilt cam 14b of the operating member 14 and receives it, and the sunshade panel 9 is supported substantially parallel to the lower rail 8b. It

When the wire 13 is further retracted, the stopper member 17 is engaged with the pin 9a, the sunshade panel 9 is positioned, and the sunshade panel 9 is also retracted as the transparent sliding roof 4 is retracted. It stops in the state shown by and the opening of the opening 3 is completed.

The opening 3 is closed by closing the operation switch. First, the detection means 6 detects that the transparent sliding roof 4 is in the position state where sliding should be started, and the detection means 6 turns off the control means 7.
A signal is input. In this case, the solenoid 7a is not energized, and the lever switch 7b is urged by the spring so that the HIG
The H contact 7c is closed, the electric motor 11 starts reverse rotation driving at high speed, the wire 13 is pulled in rather rapidly, and the transparent sliding roof 4 quickly advances by the operation opposite to the opening operation described above. Then, when the transparent sliding roof 4 reaches the position where the tilting operation should be started and the lever 25a with the roller is fitted into the cam groove 24b, the ON signal is input from the detection means 6 to the control means 7. Then, the solenoid 7a is excited, the lever switch 7b is attracted to the exciting force against the spring force, the LOW contact 7d is closed, the electric motor 11 shifts to low speed rotation, and the rear part of the transparent sliding roof 4 is slightly slowed down. Tilt down to the opening 3
Will be closed. As with the opening, the folding operation of the link 12d and the fitting operation of the transparent sliding roof 4 to the weather strip 18 provided on the inner peripheral edge of the opening 3 accompanying the tilt-down operation described above are performed slowly and smoothly.
