[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a drive device for a tilting and sliding sunroof.

[Prior Art] A drive device for a sunroof that opens a sunroof panel of an automobile or the like that has been in a closed state or tilts the rear part of the panel upward is disclosed, for example, in Japanese Patent Publication No. 12488/1988. There are descriptions etc. The device includes a drive motor capable of forward and reverse rotation, and a tilt and slide opening/closing control mechanism that is interlocked with the motor and switches the sunroof panel between a tilt state and a slide open/close state by forward and reverse rotation of the drive motor. It has a structure.

[Problems to be solved by the invention] In the case of a sunroof drive device having such a drive motor capable of forward and reverse rotation, it is an electric type that uses a solenoid to rotate the drive motor in the forward and reverse directions. There is.

This electric type drive device is undesirable in terms of failure and maintenance management.
In addition, malfunctions and malfunctions are likely to occur due to voltage fluctuations, resulting in a lack of reliability, and in some cases, troubles such as a dead battery or generation of heat may occur when a return failure occurs.

Therefore, the object of this invention is to provide a driving device for an automobile sunroof that has a simple structure, stable operation, and high reliability.

[Means for Solving the Problems] In order to achieve the above-mentioned object, this invention includes a drive motor that can rotate forwardly and rotatably, and a drive motor that can rotate forwardly or reversely by turning on from a neutral position. a control disk that rotates forward and reverse by the power of the drive motor and has a plurality of cam mechanisms formed on its outer periphery; and an actuation arm that is movable forward and backward by the cam mechanism of the control disk;
When the manual operation lever is turned on, the actuating arm is pressed in a direction perpendicular to the forward and backward direction of the operating arm to move forward, and when the on operation is released, it is possible to return to a backward position.
and a frame body that is displaced by being pushed by the actuating arm; a control switch that can be turned on and off by being pressed by the frame body when the frame body is displaced to stop the operation of the drive motor; and a control switch that can be turned on and off to stop the operation of the drive motor; a biasing means for returning the frame body to the rearward position while being displaced so as to turn off the control switch when the on-operation is released; and a locking part for locking the frame body, which has returned to the rearward position while being displaced, to the control switch and restraining it from moving forward. is provided in the frame body, and the pusher provided in the frame body and the manual operation lever are interlocked and connected, and when the control switch is off and the frame body is restrained from moving forward, the manual operation lever is activated. A pressing body is provided with an elastic portion that allows the on-operation.

[Function] In such a sunroof drive device, in order to fully close the sunroof from the tilt-up or slide open state, when the manual operation lever is turned on from the neutral position, the frame moves forward together with the pressure of the pusher. At the same time, for example, the drive motor rotates in the normal direction, and the frame is displaced by the actuating arm advanced by the cam mechanism of the control desk, and this displacement presses the switch terminal of the control switch, turning it on. As a result, the drive motor stops rotating, and the sunroof panel is fully closed. At the same time, when the on-operation of the manual operation lever is released, the frame moves back together with the pusher while being displaced by the biasing means. The control switch is turned off by the return of the frame, and the pusher is held in a restrained state by the protruding switch terminal so that it cannot move forward. Next, to tilt up and slide open from fully closed, turn on the manual operation lever again from the neutral position. At this time, the frame body is in a restrained state in a displaced state, but the elastic portion secures the movement allowance for the on-operation, so the on-operation can be performed without any problem. As a result, the drive motor rotates in the reverse direction, so that the actuating arm is moved back by the cam mechanism of the control disk, and the displaced state of the frame is released.

[Embodiment] Hereinafter, an embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 to 13.

A sunroof panel 5 is connected to a roof opening 3 provided in a roof panel 1 of an automobile in conjunction with a tilt and slide opening/closing control mechanism 7, and the control mechanism 7 is driven via a drive mechanism 9 that also serves as a speed reducer.

3, 55, and 57 (arrow A in FIG. 3), and is constantly urged by a biasing spring 89 in the backward direction on the right side in FIG. Further, the frame body 61 is supported by an operating arm 55 so as to be displaceable in a direction perpendicular to the axial direction of a pusher 63 (downward in FIG. 3). It is linked to each other. On the side of the frame 61 facing the control switches LS ₁ and LS ₂ , there is a pressing part 61b that presses the switch terminals S ₁ and S 2 when the frame is displaced when moving forward, and a pressing part 61b that presses the switch terminals S 1 and S ₂ when the frame is displaced when moving backward. It also has a non-pressing part 61c which is a concave part that does not press the switch terminals S ₁ and S ₂ , and is further provided with a stopper surface 61 a which is a locking part that can be locked to the side surface of the switch terminals S ₁ and S ₂ . It is being

A guide shaft 69 constituting the pressing mechanism 65 is fixedly supported by a U-shaped housing 67.
A rod 71 passes through the guide shaft 69 and is movable in the axial direction. One end of the rod 71 is fixed to the pusher 63, and the other end is fixed to the guide shaft 63.
9 and a flange portion 73 is formed therein. A pressing body 75 is in elastic contact with the flange portion 73, and the elastic portion 77 is hollow.
For a, a movement allowance α in the axial direction is secured.

The pressing body 75 is biased rearward (to the right in FIG. 3) by a spring 79 such as a coil spring installed in the housing 67.
Note that the positioning of the pressing body 75 is such that the stopper 81 provided on the circumferential surface of the pressing body 75 is aligned with the housing 67.
This is done by coming into contact with the On the other hand, the pressing body 75 is connected to the lever portion 13a of the manual operation lever 13 via a stiff wire cable 83.

The manual operation lever 13 is built into the case 85 and can be turned on from the neutral position N to the first actuation position F or the second actuation position R.
A leaf spring 87 is in elastic contact with the base of the lever portion 13a.
is always positioned at the neutral position N. The operating amount H of the lever portion 13a from the neutral position N to the first or second operating position F, R is the amount of pressure to press the pressing body 75. Note that the contacts P ₁ and P ₂ are arranged at the first and second operating positions F and R.

As a result, by switching the lever part 13a to the first and second operating positions F and R, the contact _P1 or the contact

It protrudes between each switch terminal S ₁ and S ₂ of LS ₂ .

Note that the spring pressure of the biasing spring 89 is
The setting is weaker than the elastic deformation force of No.7.

Next, the operation will be explained based on FIGS. 8 to 11. In FIGS. 8a, b, c, and d, the sunroof panel 5 is in the fully closed state, the manual operation lever 13 is in the neutral position N, and the first and second relay switches LR ₁ ,
The contacts a and c of LR ₂ are connected, and the contacts d and e of the first and second control switches LS ₁ and LS ₂ are connected, so that the drive motor 11 is in a non-operational state. That is, the intermediate actuating arm 55 is in the forward operating state due to the protrusion 49B of the control disk 49, and the frame 61 is in the third position.
As shown by the chain line in the figure, the vehicle is in a backward state and is in a restrained state displaced downward in the drawing, and the first control switch is
LS ₁ is a switch terminal due to the displacement of the frame 61.
S ₁ and S ₂ are in an off state in which they protrude into the non-pressing portion 61c of the frame 61. In addition, the frame body 61 has a stopper surface 6
1a is locked to the side surfaces of the switch terminals S ₁ and S ₂ , and is in a restrained state where it cannot move forward.

In this state, in order to tilt up the sunroof panel 5, the lever portion 13a of the manual operation lever 13 is turned on to the contact _P1 side as shown in FIG. At this time, the frame body 61 is in a restricted state in which it is displaced and cannot move forward, but the collapse of the elastic portion 77 ensures a movement allowance α, so that the ON operation can be performed without any trouble. On the other hand, the coil C of the second relay switch _LR2 is energized and the switch arm is switched from contact point c to contact point b. The current flows through contacts e and d of the second control switch LS ₂ to the drive motor 11 and rotates forward (clockwise).
do. At the same time, the control disk 49 also rotates in the direction of the arrow, and the protrusion 49c comes into contact with the lower actuating arm 57, causing the second
Press switch terminal _S2 of control switch _LS2 .
On the other hand, the second control switch is activated by pressing switch terminal _S2 .
The contact point of LS ₂ switches from e to f (dotted line in the figure) to cut off the circuit of the drive motor 11, and the motor 11 stops, completing the tilt-up. On the other hand, the intermediate actuating arm 55 retreats, the displacement state of the frame body 61 is released, and it becomes possible to advance, and moves forward against the biasing spring 89 by the biasing force of the elastic portion 77 of the pressing body 75.

Next, the sunroof panel 5 in the tilted up state
To return to the fully closed state again, as shown in FIG. 10, the lever portion 13a of the manual operation lever 13 is turned on beyond the neutral position N and further toward the contact _P2 side using the circuit shown in FIG. At this time, the pusher 63 (frame body 61) is pressed via the pressing body 75 against the biasing spring 89. At the same time, the coil C is energized, the first relay switch LR ₁ is activated, and the current flows to the drive motor 11 through contacts e and d of the first control switch LS ₁ and is reversed (counterclockwise). At the same time, the control disk 49 also rotates, and the protrusion 49B
5. The intermediate actuating arm 55 moves forward again and presses the frame 61. As a result, the first and second
Switch terminals S ₁ and S ₂ of the control switches LS ₁ and LS ₂ are pressed simultaneously through the frame 61. Therefore, the contacts of the first and second control switches LS ₁ and LS ₂ are switched from e to f, the circuit of the drive motor 11 is cut off, and the sunroof panel 5 is completely closed. When the lever portion 13a is returned to the neutral position N after the full closing is completed, the frame body 61 returns to the backward position while being displaced by the biasing spring 89. At this time, switch terminals S ₁ and S ₂ are
The frame body 61 is in a protruding state facing the non-pressing portion 61b, and the stopper surface 61a is engaged with the switch terminals S ₁ and S ₂ , and the frame body 61 is restrained from being able to move forward while returning to the backward position in the displaced state. At the same time, the contacts of the first and second control switches LS ₁ and LS ₂ are switched from f to e and turned off. (Fig. 8) Next, in order to slide the sunroof panel 5 to the fully open state, the lever portion 13a of the manual operation lever 13 is turned on to the _P2 side using the circuit shown in Fig. 10. At this time, the elastic portion 77 is crushed and the movement allowance α is secured, so that the manual operation lever 13 can be turned on without any trouble.

Therefore, as shown in FIG. 11, the coil C of the first relay switch _LR1 is energized and the contact point c is switched to the contact point b. The current flows through contacts e to d of the first control switch LS ₁ to the drive motor 11 and reverses (counterclockwise), causing the protrusion 49 of the control disk 49 to flow.
A contacts the upper actuating arm 53 and presses the switch terminal _S1 of the first control switch _LS1 . At the same time, the contact switches from e to f, which turns it into an off state (dotted line in the figure), cutting off the circuit of the drive motor 1 and stopping the motor 11. At this time, the sunroof panel 5 is fully opened.

Next, in order to fully close the sunroof panel 5, the lever portion 13a of the manual operation lever 13 is turned on beyond the neutral position N to the contact _P1 side from the state shown in FIG. At this time, since the elastic portion 77 is crushed and the movement allowance α is secured, there is no problem in the ON operation. On the other hand, coil C of second relay switch LS ₂
is excited and switches from contact C to b. The current flows through the contacts e and d of the second control switch LS ₂ to the drive motor 11, causing it to rotate in the forward direction (clockwise), causing the control disk 4 drive to rotate in the opposite direction to the arrow.
The protrusion 49B abuts the intermediate actuation arm 55. As a result, the switch terminals S ₁ and S ₂ of the first and second control switches LS ₁ and LS ₂ are simultaneously pressed through the frame 61, and the contacts are switched from e to f, respectively, and the circuit of the drive motor 11 is cut off. The motor 11 stops and the sunroof panel becomes fully closed. (Figure 10)
In addition, when the sunroof panel 5 is fully closed,
By moving the lever portion 13a of the manual operation lever 13 to the center position N, the frame body 61 returns to the backward position while being displaced by the biasing spring 89, and the control switch _LS1 is turned off.

[Effects of the invention] As explained above, according to the automotive sunroof drive device of this invention, the selection of each posture position of the sunroof panel is activated by a manual operation lever, which prevents malfunctions and breakdowns. gone,
Reliability can be improved. Additionally, since there is no solenoid, the structure is simpler, making it possible to reduce weight and cost.
