Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a drive device for automatically opening and closing a sliding roof of an automobile. The present invention relates to a device that can be stopped automatically to ensure safety.

(Prior art) A sliding roof of an automobile is moved by a driving means such as a motor to a fully open position, a fully closed position, and a tilt position where one end of the sliding roof is lifted above the roof and tilted. Such a drive device is known (for example, see Japanese Utility Model Publication No. 58-585).

(Problem to be Solved by the Invention) However, in such conventional devices, the sliding roof closes all at once from the fully open position to the fully closed position. There was a problem in that there was a risk that a part of the person's body could get caught when the sliding roof was closed, causing damage.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a sliding door in which a lid provided on the roof opening of an automobile is driven to open and close by a motor provided at an appropriate location on the vehicle body. In the riding roof drive system,
A rotary plate that is linked to the rotating shaft of the motor and rotates forward and backward in synchronization with the movement of the lid body by the operation of the motor, protrudes from the surface of the rotary plate when the rotary plate rotates in one direction, A retractable operating piece is provided which operates a switch that temporarily stops the motor, and when the rotary plate rotates in the other direction, retracts from the surface of the rotary plate and disables the switch.

(Function) In the present invention, the sliding roof is
When moving the sliding roof in one direction, for example from the fully open position to the fully closed position, the operating piece activates the motor temporary stop switch and temporarily stops the sliding roof. Conversely, when moving the sliding roof in the other direction, for example from the fully closed position to the fully open position, the operating piece does not actuate the switch and the sliding roof is moved without temporarily stopping. It can move continuously and achieve a balance between ensuring safety and speed of operation.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIGS. 3 to 5, 1 is the roof of the automobile, 2 is an opening provided in the roof 1, and 3 is
It is guided by an appropriate guide device (not shown) and can be moved to a fully open position as shown in FIG. 3, a fully closed position where the opening 2 is completely closed as shown in FIG. 4, and a fully closed position as shown in FIG. This is a so-called sliding roof whose rear end is lifted above the roof 1 from the closed position and is movable to a tilt position where the rear part is tilted upward.

Reference numeral 4 denotes a sliding roof drive device for moving the lid 3, which is provided so as to be movable in the front-rear direction below the movement trajectory of the lid 3 and the drive device main body 5 provided at the front lower part of the roof 1. The trolley 6 is connected to the drive device main body 5,
It consists of a cable 7 that pulls the truck 6 forward or pushes it backward, and a connecting ring 8 that connects the truck 6 and the lid 3.

The cable 7 is a known so-called geared cable in which a spiral protrusion 7a is formed by spirally winding a hard steel wire or the like around the outer periphery.

The above configuration is almost the same as the configuration disclosed in the above-mentioned Japanese Utility Model Publication No. 58-585, but the present invention has features in the drive device main body 5 as described below.

As shown in FIGS. 1 and 2, the drive device main body 5 includes a case 12 having a motor housing chamber 9, a gear chamber 10, and an electrical chamber 11, and a lid 13.

A reversible motor 14 is provided in the motor housing chamber 9, and a worm 15 is fixed to a rotating shaft 14a of the motor 14.

A worm wheel 16 that meshes with the worm 15 is provided in the gear chamber 10 so as to be able to rotate integrally with the output shaft 17.

An output shaft 1 that passes through the lid 13 and projects upward.
A pinion 18 that meshes with the spiral protrusion 7a of the cable 7 is firmly fitted to the upper end of the cable 7.

The pinion 18 is rotated in forward and reverse directions by the operation of the motor 14, and the pinion 18 is rotated forward and backward by the operation of the motor 14, and the cable 7 The cover body 3 can be opened and closed by pushing or pulling the cover body 3.

In the gear chamber 10, an intermediate gear 19 is further provided with a shaft 20, and the intermediate gear 19
The large diameter first gear 19a is the worm wheel 1
6 and meshes with the key gear 16a. A small-diameter second gear 19b of the intermediate gear 19 that is integral with the first gear 19a meshes with a large-diameter gear plate 22d formed on a rotary plate 22 that is pivotally mounted in the gear chamber 10 with a shaft 21. are doing.

Thus, the rotary plate 22 connects to the lid body 3 via the intermediate gear 19, the component gear 16a, the output shaft 17, the pinion 18, the cable 7, the trolley 6, the connection link 8, etc.
The lid body 3 and are linked to each other.

The rotating plate 22 is a small diameter plate 22a whose diameter gradually increases.
It consists of an integral body in which a medium-diameter plate 22b, a large-diameter plate 22c, and the aforementioned gear plate 22d are coaxially stacked.

A tilting protrusion 23 is provided on the outer periphery of the small diameter plate 22a.
However, a fully closing protrusion 24 is provided on the outer periphery of the medium diameter plate 22b.
However, on the outer periphery of the large diameter plate 22c, there is a protrusion 2 for fully opening.
5 are provided in a positional relationship as will be described later.

A recess 26 is formed in a part of the outer periphery of the small diameter plate 22a and the medium diameter plate 22b, and in this recess 26,
An actuating piece 27 is pivoted.

As shown by the solid line in FIG. 1, this actuating piece 27 is in a protruding position where one side edge abuts one side surface of the recess 26 and a pointed tip protrudes from the outer circumferential surface of the medium diameter plate 22b. , as shown by the imaginary line in FIG. , is biased clockwise in FIG. 1 by a coiled spring 29 having a relatively small spring constant, and is normally stopped at the protruding position.

27a, when the actuating piece 27 is in the protruding position,
This is a step formed on the upper surface of the actuating piece 27 so as to be continuous with the outer peripheral surface of the small diameter plate 22a.

Gear chamber 10 and electrical chamber 11 in case 12
In the partition wall 12a formed between They are installed through each of them so that they can appear and appear towards each other.

The upper slider 30 is connected to the small diameter plate 22a, the middle slider 31 is connected to the medium diameter plate 22b, and the lower slider 3 is connected to the small diameter plate 22a.
2 are located on the same horizontal plane as the large-diameter plate 22c, and the tip of the slider 30 in the upper stage is on the outer peripheral surface of the small-diameter plate 22a, and the tip of the slider 31 in the middle is on the same horizontal plane as the medium-diameter plate 22.
The outer circumferential surface of b and the tip of the lower slider 32 are in a positional relationship such that they can come into sliding contact with the outer circumferential surface of the large-diameter plate 22c, respectively.

Further, the positional relationship between the respective projections 23, 24, and 25 described above is such that when the lid body 3 reaches the tilt position, the tilting projection 23 comes into sliding contact with the tip of the upper slider 30, and the slider 30 When the lid body 3 reaches the fully closed position, the fully closing protrusion 24 comes into sliding contact with the tip of the middle slider 31 and pushes the slider 31 forward, When the lid body 3 reaches the fully open position, the fully opening protrusion 25 comes into sliding contact with the tip of the lower slider 32 and pushes the slider 32 forward.

Furthermore, the positional relationship of the actuating piece 27 is such that when the lid body 3 is on the way from the fully open position to the fully closed position, the tip of the actuating piece 27 in the protruding position touches the middle slider 31.
slidingly contacts the tip of the slider 31 and pushes the slider 31 forward;
On the other hand, when the lid body 3 is on its way from the fully closed position to the fully open position, the tip of the actuating piece 27 touches the middle slider 31.
However, since the spring constant of the coiled spring 29 is small, the actuating piece 27 itself is rotated to the retracted position and the slider 31 cannot be pushed forward.

At the front of the electrical chamber 11 in the case 12, two microswitches 33 and 34 are provided, upper and lower.

When the upper slider 30 is pushed forward,
At its base end, the actuating part 33a of the upper micro switch 33 can be pushed, and the lower slider 3
2 is pushed forward, the operating portion 34a of the lower micro switch 34 can be pushed by its base end.

A frame 35 having a rectangular side surface is provided between the upper slider 30 and the lower slider 32 and in front of the middle slider 31.

This frame 35 is supported by a pair of front and rear flexible arms 39 and 40 extending from a base plate 38 fixed to the tip of a plunger 37 that protrudes from a solenoid 36 provided in the electrical room 11. At the same time, the leaf spring 4 has one end fixed to the plunger 37.
1 is constantly biased toward the middle slider 31, that is, toward the rear.

42 is a compression spring that biases the plunger 37 in the direction of pushing it into the solenoid 36.

When the solenoid 36 is energized, the frame body 35 is located at an operating position opposite to the operating parts 33a, 34a of the upper and lower micro switches 33, 34, as shown by solid lines in FIG. ,
In this state, when the middle slider 31 is pushed forward, the operating portions 33a and 34a of the upper and lower microswitches 33 and 34 are simultaneously pushed via the frame 35. Also, solenoid 3
6 is demagnetized, the frame 35
As shown by imaginary lines in the figure, the micro switches 33, 34 are pushed by the compression spring 42 and are located in the inoperative position, which is laterally removed from the operating parts 33a, 34a of the upper and lower micro switches 33, 34. The slider 31 prevents the operating parts of either the upper or lower microswitches 33 and 34 from being pushed no matter how much the frame body 35 is pushed forward.

FIG. 6 is a diagram schematically showing the motor control circuit and a part of the mechanism of the drive device main body 5. As shown in FIG.

In FIG. 6, 43 is a DC power supply, 44 is 2
Continuous operation switch, 44a, 44b, 44c
is the switching contact.

In FIG. 6, the same reference numerals as in FIGS. 1 and 2 indicate the same members as already described.

Note that 33b, 33c, 34b, and 34c represent switching contacts of the microswitches 33 and 34, respectively.

Next, the operation of this embodiment will be explained with reference to FIG. 6.

In the following explanation, the rotation direction of the motor 14 and the rotation direction of the rotary plate 22 when the lid body 3 moves from the fully open position to the fully closed position and the tilt position will be temporarily referred to as the normal rotation direction, and these directions will be referred to as normal rotation directions. The rotation in the opposite direction will be referred to as the reverse direction.

When the lid body 3 is in the fully open position, the rotating plate 22 is
The full opening protrusion 25 stops at a position where it contacts the slider 32, and the slider 32
, the actuating part 34 of the micro switch 34
a, and the micro switch 34 connects to contact 3.
It has been switched to the 4b side.

Since no external force is applied to the operating portion 33a of the microswitch 33, the microswitch 33 is switched to the contact 33c side.

In this state, when the operation switch 44 is operated from the neutral position to the "close/tilt up" direction, a circuit of the positive pole of the power supply 43 - the contact 44a - the contact 33c - the motor 14 - the contact 34b - the negative pole of the power supply 43 is formed. As a result, the motor 14 rotates in the normal direction, the lid 3 begins to close, and the rotating plate 22 also begins to rotate in the normal direction. In addition, at this time, solenoid 3
6 is also energized and excited, and the frame body 35 is positioned at the operating position.

When the lid body 3 moves slightly from the fully open position to the fully closed position, the fully open protrusion 25 is removed from the slider 32 and the micro switch 34 is switched to the contact 34c side.

Immediately, motor 1 in the circuit described above
4 to the negative pole of the power source 43 is switched to a circuit of the motor 14 - contact 34c - contact 44b - negative pole of the power source 43, but the rotation direction (forward rotation) of the motor 14 remains unchanged and the lid 3 remains unchanged. Continue the closing operation.

When the lid body 3 reaches an appropriate intermediate position from the fully open position to the fully closed position, the actuating piece 27 moves the slider 3 at the middle stage.
1 and the operating portions 33a and 34a of both micro switches 33 and 34 are pushed via the frame 35 which is in the operating position, and both micro switches 33 and 34 are switched to the contact points 33b and 34b side.

Then, contact 33b-motor 14-contact 34b
- A closed circuit of contacts 33b is formed, and the motor 14 is short-circuited and stops immediately.

Therefore, if you have taken objects or hands out of the vehicle through the opening 2 by this time, the lid 3 at this time
The stoppage of the vehicle allows room for them to be pulled into the vehicle.

If it is desired to further close the lid 3 from this state, the operation switch 44 is temporarily returned to the neutral position.

Then, the solenoid 36 is demagnetized and the frame 35
is returned to the inoperative position shown in phantom lines in FIGS. 1 and 6, and both microswitches 33 and 34
is switched to the contact 33c, 34c side.

In this state, turn the operation switch 44 again.
When operated in the "tilt up" direction, the circuit is the same as the state before the above-mentioned actuating piece 27 comes into contact with the slider 31, that is, the positive pole of the power source 43 - the contact 44a
- Contact 33c - Motor 14 - Contact 34c - Contact 4
4b - A negative pole circuit of the power supply 43 is formed,
The motor 14 rotates normally again, and the lid 3 moves toward the fully closed position again.

At this time, the solenoid 36 is also energized again, but while the actuating piece 27 is pushing the slider 31, the slider 31 and both micro switches 33,
34 operating parts 33a, 34a, the frame 35
is prevented from moving into the working position, and only after the working piece 27 has passed the slider 31 does the frame 35 move into the working position.

When the lid body 3 reaches the fully closed position, the fully closing protrusion 24 pushes the middle slider 31, and the motor 14 stops in the same way as when the slider 31 is pushed by the actuating piece 27 described above. At the same time, the movement of the lid 3 and the rotation of the rotary plate 22 are also stopped.

From this state, when the operating switch 44 is returned to the neutral position and operated again in the "close/tilt up" direction, the motor 14 is rotated in the normal direction again as in the case described above, and this time the lid body 3 is directed to the tilted position. It can be moved by

When the lid 3 reaches the tilt position, the tilt projection 23 comes into contact with the upper slider 30, and only the upper micro switch 33 is switched to the contact 33b side.

Then, contact 33b-motor 14-contact 34c
- A closed circuit of contacts 44b and 33b is formed,
Motor 14 stops.

From this state, once the operation switch 44 is returned to the neutral position and then operated in the direction of "open/tilt down", the positive pole of the power supply 43 - contact 4
4b-contact 34c-motor 14-contact 33b-a negative pole circuit of power supply 43 is formed, and motor 1
4 is reversed, and the lid body 3 is moved from the tilted position toward the fully closed position.

When the lid body 3 reaches the fully closed position, the fully closed protrusion 24
As a result, the slider 31 is pushed, and the actuating parts 3 of both the micro switches 33 and 34 are pushed through the frame 35.
3a, 34a are pressed, both micro switches 3
3 and 34 are switched to the contacts 33b and 34b side,
The motor 14 is short-circuited and the lid 3 stops.

This state is the same as when the lid body 3 described above reaches the fully closed position from the fully open position side.

From this state, once the operation switch 44 is returned to the neutral position and then operated in the "open/tilt down" direction again, the motor 14 is reversed again.
The lid body 3 can be moved toward the fully open position.

Note that until the full-closing protrusion 24 completely passes the slider 31, the return of the frame 35 to the operating position is prevented by the slider 31 and the operating parts 33a, 34a of both the micro switches 33, 34. As in the case described above, the frame body 35 returns to the operating position only after the fully closing protrusion 24 has completely passed through the slider 31.

When the lid body 3 reaches an appropriate intermediate position between the fully closed position and the fully open position, the tip of the actuating piece 27 comes into contact with the slider 31, but in this case, the coiled spring 29
The actuating piece 27 is pushed to the retracted position by the slider 31 against the urging force of the slider 31, and the slider 31 does not move.

Therefore, when the lid body 3 is opened from the fully closed position to the fully open position, it can be opened continuously and quickly without being temporarily stopped in the middle.

When the lid body 3 reaches the fully closed position, the fully opening protrusion 25
As a result, the slider 32 is pushed, and only the lower micro switch 34 is switched to the contact 34b side, and the contact 34b - the motor 14 - the contact 33c - the contact 44c.
- A closed circuit of contacts 34b is formed, and the motor 14 is short-circuited and stopped.

Thereafter, when the operating switch 44 is returned to the neutral position, the initial state is restored.

In this embodiment, when the rotary plate 22 rotates in one direction, it is operated by the actuating piece 27, and when the rotary plate 22 rotates in the other direction,
Two micro-switches 3 that can simultaneously operate a temporary stop switch that cannot be operated by the operating piece 27 via the slider 31 and the frame 35.
3 and 34, it goes without saying that such a temporary stop switch may be provided separately from the other circuit components.

(Effect of the invention) As is clear from the above, in the present invention,
When the lid body moves in one direction, the lid body must be stopped temporarily in the middle, and conversely, when the lid body moves in the other direction, it moves continuously without being paused. This makes it possible to prevent objects or hands from getting caught, and to improve the speed of operation compared to a system in which the lid is always stopped temporarily when moving back and forth. , meaningful.
