BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile sunroof device.

[0002]

2. Description of the Related Art Generally, in a sunroof device for an automobile, a tilt-up function for raising a rear end side of a lid (cover) in a fully closed state and a fully closed state as described in JP-A-1-282018, for example. It further has a sliding function that further opens the roof opening by further lowering and sliding backward.

[0003]

As described above, in the sunroof device, the tilt-up control and the slide control of the lid are intended. For example, the motor is rotated in the reverse direction from fully closed to tilt-up. use. Also, from the tilt-up position to the slide opening position where the lid is moved rearward, the motor is rotated in the reverse direction so that the motor is moved to the slide opening position by passing through the fully closed position and the tilt down position. Is set to approximately the middle of the operation range between the lid tilt-up position and the slide opening position. Therefore, it is difficult to accurately detect the stop of the motor at the fully closed position of the lid, and a step may occur between the lid and the roof. Further, there is a problem that the control system of the motor becomes complicated, such as detection of switching between forward rotation and reverse rotation of the motor with the fully closed position as a boundary.

Further, since the lid is moved up and down in the fully closed position by the connecting bolt which slides in the sliding path which is inclined downward in the front-rear direction, a slight amount is required to allow the sliding movement between the sliding path and the connecting bolt. Play is secured.
On the other hand, this play appears as a rattling noise during running, and there is a problem that the quality is deteriorated.

Therefore, in the present invention, the lid can be surely stopped at the fully closed position with a simple structure, and
It is an object of the present invention to provide a sunroof device for an automobile that does not cause rattling.

[0006]

In order to achieve the above object, according to the present invention, the front side of the lid provided in the roof opening is supported by a movable shoe that can move back and forth, while the rear side of the lid is The lift mechanism is movably supported up and down, and the lift mechanism has a guide groove consisting of a tilt-down guide part in the front, a tilt-up guide part in the center, and a fully-closed guide part in the rear, and can be moved back and forth by a driving means. One end of the movable shoe is pivotally supported on the lid side, and the other end of the guide shoe is engaged with the fully closed guide portion of the guide groove, the tilt-up guide portion, and the tilt-down guide portion in this order through a reciprocating engagement body. It is composed of a lifting arm. Then, as a preferred embodiment, when the lid is fully closed, the engaging body comes into strong contact with the guide end of the fully closed guide portion to face it.

[0007]

In such a sunroof, for example, in order to slide and open the lid at the time of tilting up, the rear moving shoe constituting the lifting mechanism is moved backward by the driving means. By the backward movement, the engaging body located in the tilt-up guide portion of the guide groove moves to the tilt-down guide portion, and the elevating arm descends. This causes the lid to further descend beyond the fully closed position. If the moving shoe is further moved rearward from this state, the lid is moved rearward, and a slide opening state in which the roof opening is wide open is obtained.
In this case, the series of lid operations need only be a single operation of moving the moving shoe rearward, so that the control system of the drive means can have a simple structure.

Further, in order to fully close the roof opening,
Move the moving shoe forward. At this time, the engaging body slides in the order of the tilt-down guide portion, the tilt-up guide portion, and the fully-closed guide portion, and the lid tilts up once and then descends to obtain a fully closed state. Since the engaging body when the lid is fully closed makes strong contact with the guide end of the fully closed guide part,
The raising and lowering arm and the moving shoe are held in a pressed state, and no rattling occurs.

And a stator (not shown) integrated with
The movement of the geared cable 43 allows the rear moving shoe 25 to slide back and forth.

Next, the operation of the sunroof device thus constructed will be described. First, in the lid 9 in the fully closed state, the geared cable 43 is driven to move the rear moving shoe 25 rearward (right side in FIG. 2). At this time, the first engaging body 31 reaches the tilt-up guide 27c from the fully closed guide portion 27a of the guide groove 27. At the same time, the second engagement body 33 also extends from the fully closed guide portion 29a to the tilt-up guide portion 39c, and as a result, the lid 9 is in the tilt-up state shown in FIG.

Next, in order to change the tilt-up state to the fully closed state, the rear moving shoe 25 is moved forward. As a result, the first and second engaging bodies 31 and 33 return to the fully closed guide portions 27a and 29a of the guide grooves 27 and 29, respectively.
The fully closed state shown in is obtained. In order to open the slide from the tilt-up state, the geared cable 63 is driven to move the rear moving shoe 25 rearward, and the first and second engaging bodies 31 and 33 move the tilt-up guide portions 27b and 27b.
It moves from 29b to the tilt-down guide portions 27a and 29b. At this time, the lifting arm 23 rotates counterclockwise,
A tilt-down state is obtained in which the rear end side of the lid 9 is lower than the outer panel 5 (see FIG. 3). When the geared cable 43 is further driven in the same direction from this state, the front and rear moving shoes 19, 25, the lid 9 and the like move integrally into the rear roof space W, and the roof opening 7 is opened greatly. can get.

This series of operations is performed by the rear moving shoe 25.
Can be moved backward by a single operation (see FIGS. 2, 3 and 4).

Next, in order to bring the lid 9 into the fully closed state, the rear moving shoe 25 is moved forward, so that each engaging member 3
Reference numerals 1 and 33 extend from the tilt-down guide portions 27a and 29a to the fully-closed guide portions 27c and 29c via the tilt-down guide portions 27a and 29b. At the same time, the lid 9 tilts up for a moment and then descends again to obtain a fully closed state. This time,
The first and second engaging bodies 31, 33 are fully closed guide portions 27c,
Since the guide ends 27d and 29d of 29c are in strong contact with each other, the lifting arm 23 and the moving shoe 25 are strongly suppressed, and there is no fear of rattling due to the influence of vibration or the like.

[0022]

As described above, according to the sunroof device of the present invention, a single operation of moving the moving shoe on the lifting mechanism side to the rear is required when the sliding opening is performed from the time of tilting up, and therefore the driving is performed. The control system of the means has a simple structure and is very preferable in terms of cost.

Further, since the fully closed position of the lid is set at one end of the operation range of the lid, the fully closed position of the lid can be easily and surely obtained, and
Since the engaging body makes strong contact with the guide end of the fully closed guide part,
The lifting arm and the entire moving shoe are pressed down, and it is possible to prevent rattling.
