DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sunroof device used in an automobile.

[Prior art] A conventional sunroof device is, for example, disclosed in Japanese Utility Model Application No. 58-157.
As seen in Japanese Patent No. 822, a tilt-up state can be obtained by raising the rear part of the lid. Also,
The roof opening can be opened by sliding it backwards.

[Problems to be Solved by the Invention] As described above, the roof opening can be opened by sliding the lid rearward. As a result, it becomes difficult to secure storage space for storage.
To open and close the roof opening, the lid is kept tilted up and slid toward the rear and upper part of the roof opening.

However, the lid has a shape that protrudes significantly upward from the rear part of the roof opening, which causes wind noise. In addition, when the back door is opened, the rear opening is restricted so as not to interfere with the lid, so there is a problem in that the opening of the roof opening is restricted.

SUMMARY OF THE INVENTION An object of the present invention is therefore to provide a sunroof device that can secure a large roof opening m and is also favorable in terms of wind noise.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a plurality of lids provided at the roof opening of a vehicle body, tilting up each lid from a fully closed state, and opening the roof. an elevating mechanism that is movable back and forth to move the rear part of the opening upward; and an elevating mechanism driving body that is connected to the other end of a guard cable whose one end is connected to a driving means and that is movable back and forth in conjunction with the elevating mechanism. It consists of

[Operation] In this device, the plurality of lids can be brought into a tilted-up state and a fully open state by the elevating mechanism operated by the elevating mechanism driver. Further, by moving the lifting mechanism rearward, it tilts up from the fully open state and moves upward to the rear of the roof opening while remaining tilted up. As a result, a large roof opening can be secured. Also, the protruding nails on the lid can be kept small, which is good for reducing wind noise.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings of FIGS. 1 to 11.

In the figure, reference numeral 1 indicates a roof consisting of an inner panel 3 and an outer panel 5, and the roof 1 is provided with a lower roof opening.

It is rotatably pivoted by 5. Further, one end of the second link 27 is rotatably pivoted to a substantially intermediate portion of the first link 25 by means of a pin 37. The other end is the first
It is rotatably attached to the attachment part 39 of the movable shoe 17 by a pin 41, and when the slider 31 moves rearward (to the right in FIG. 4), the rear end side of the first lid 9 rises and moves forward. It will start to descend.

The slider 31 is placed and set inside the first movable shoe 17 so as to be movable back and forth, and is operatively connected to a swinging arm 45 via an elevating and lateral driving body 43.

The swinging arm 45 is rotatably supported by the first movable shoe 17 about an arm shaft 47 as a fulcrum, and has a roller-shaped locking portion 49 on the arm body and a long guide groove 51 longitudinally along the arm body. is formed. The locking portion 49 engages with the first rule opening hole 53 provided in the guide rail 15 when the first lid 9 is fully opened. Locking part 49
is biased by a coil spring (not shown) attached to the arm shaft 47 so as to be able to engage with the first rule opening hole 53 at all times, and the first movable shoe 17 is pushed forward and backward in the front and back direction (left and right in FIG. 5). movement is now regulated.

The guide groove 51 consists of a horizontal part 51a and an inclined part 51b, and a connecting pin 55 extending downward from the lifting mechanism driving body 43 passes through the tip edge of the horizontal part 51a.
The tip of the slider 31 is fitted into the slider 31 through the pin 55.
1 and the lifting mechanism drive body 43 are integrated.

A guard cable 57 that meshes with a drive gear of a drive motor (not shown) is fixed to the base 43a of the lifting mechanism driver 43, and movement of the cable 57 allows the lifting mechanism driver 43 to move back and forth. As a result, the slider 31 is moved back and forth (left and right in FIG. 5) together with the lifting mechanism driver 43 by a drive motor (not shown). Note that the horizontal portion 51a of the guide groove 51 does not allow the swinging arm 45 to slide even if the connecting bottle 55 slides while the lids 9 and 11 are tilted up and down.
It is an area where no color tube is given. The inclined part 5111 rotates the swinging arm 45 clockwise when the connecting pin 55 of the lifting mechanism drive body 43 reaches the inclined part 51b from the horizontal part 51a, so that the locking part 49 and the first rule opening hole 53 are connected to each other. This is an engagement release area where engagement is released.

On the other hand, the elevating mechanism 23 of the second lid 11 is configured similarly to the elevating mechanism 23 on the first movable shoe 17 side, and includes a first link 25 and a second link 27. One end of the first link 25 is rotatably connected to the bracket 13 by a pin 29 for mounting the second lid 11, and the other end is rotatably connected to the mounting portion 61a of the slider 61 by a pin 35. ing. Further, one end of the second link 27 is rotatably attached to a substantially intermediate portion of the first link 25 by a pin 37, and the other end is attached to a mounting portion 63 of the second movable shoe 59.
The second lid 1 is rotatably connected to the bin 41 at the rear of the slider 61 (right side in FIG.
The rear end side of 1 will rise.

The slider 61 is placed and set inside the second movable shoe 59 so as to be movable back and forth, and a swing arm 67 is provided on the upper surface.

The swinging arm 67 is formed in an E-shape and is rotatably supported by the slider 61 about an arm shaft 69 in the center as a fulcrum. A roller-shaped locking portion 71 is provided at one end of the swing arm 67, a transfer row 573 is provided at the other end, and an engagement recess 75 is provided in the main body. Locking part 7
1 and the transfer roller 73 rise from the second moving shoe 59 when the second lid 11 is fully opened, and come into contact with a rising wall 81 having a cam convex portion 77 and an engagement hole 79 inside,
The locking portion 71 of the swing arm 67 is urged counterclockwise, that is, toward the rising wall 81, by a coil spring 83 attached to the arm shaft 69.

The distal end portion 65a of the elevating mechanism drive body 65 is removably engaged with the engagement recess 75 of the slider 61.

Further, the base 65b of the lifting mechanism driving body 65 is fixed to the guard cable 57, and the movement of the cable 57 allows the lifting mechanism driving body 65 to move in the front and rear directions (left and right in FIG. 6).

The engagement hole 79 formed in the rising wall 81 engages the guide rail 15 when the second moving shoe 59 moves fully backwards.
The second rail opening hole 85 is set at a position opposite to the second rail opening hole 85 provided in the second rail opening hole 85 .

As the locking portion 71 of the swing arm 67 falls through the engagement hole 79 to the second rail opening hole 85, the tip portion 65a of the lifting mechanism drive body 65 comes to be disengaged from the engagement recess 75. As a result, the elevating mechanism drive body 65 moves to the second moving shoe 5.
9 becomes a free state, and the front lifting/lowering mechanism driving body 43 becomes able to move rearward together with the first moving shoe 17. At this time, the engagement recess 75 is set in an engagement standby state as shown in FIG.

The slider 61 also has an extension arm 87 extending rearward.
is provided, and the tip 89 engages the locking rod 91 when moving backward.
It comes into contact with the hook portion 99 of.

The locking rod 91 is rotatably connected to the second moving shoe 59 by a pin 93, and the guide rail 15 is connected to -1.
A roller-shaped locking portion 97 that removably engages with the third rail opening hole 95 is provided, and the hook portion 99 is provided at the other end. The locking rod 91 is biased counterclockwise by a biasing spring 101, and when the second lid 11 is fully opened, the protrusion 91a of the locking rod 91 touches the side surface 89b of the tip 89 of the extension arm 87. are in contact. This protrusion 91
When a is in contact with the locking portion 97, the third rail opening hole 95
The second movable shoe 59 is kept in an engaged state with the second movable shoe 59, so that movement in the front and rear directions is restricted.

Next, the operation will be explained. In order to tilt up the first and second lids 9 and 11 that are in the fully open state, the lifting mechanism drive bodies 43 and 65 are moved by the guard cable 57.
move backwards. With this movement, the sliders 31 and 61 of the first and second movable shoes 17 and 59 move backward, and the first and second lids 9 and 11 are moved to the front bin 21 via the elevating mechanisms 23 and 23. - A tilt-up state in which the rear end side rises using 21 as a fulcrum can be obtained. (Figure 2).

In this case, the first and second lids 9 and 11 can be fully opened by moving the lifting mechanism drive bodies 43 and 65 forward.

Next, when the lifting mechanism drive bodies 43 and 65 are moved further rearward from the state in which the first and second lids 9 and 11 are tilted up, the connecting bin 55 on the first moving shoe 17 side is moved into the guide groove 51. When the inclined part 51b is reached, the locking part 49 is removed from the first rule opening hole 53 and the restraint is released. At this time, the second
The hook portion 99 of the locking rod 91 on the movable shoe 59 side is pushed by the tip portion 89 and rotates, and the locking portion 97 is removed from the third roof opening hole 95 and the restraint is released.
The second moving shoes 17 and 59 move rearward together. As a result of this movement, the second movable shoe 59 comes into contact with the rear end of the lower roof opening, and the second lid 11 assumes a position facing upward to the rear as shown by the solid line in FIG.

On the other hand, the locking portion 71 of the rear swinging arm 67 has an engaging hole 79.
falls into the second rail opening 85 and restrains the second moving shoe 59 against the guide rail 15, and the lifting mechanism driver 65 disengages from the engagement recess 75 and moves forward independently (FIG. 8). However, the front elevation mechanism driver 43 continues to move the first moving shoe 17 backward. This allows the third
As shown by the chain line in the figure, the first lid 9 in the tilted-up state overlaps the second lid 11 and faces the rear upper part of the roof opening lower part. As a result, the rearward upward protrusion ω of the lids 9 and 11 is halved, and wind noise is suppressed to a minimum. Moreover, a large amount of frontage can be secured between the roofs.

Next, in order to fully close each of the lids 9 and 11 in the open state located above the rear part of the roof opening lower part, the lifting mechanism drive bodies 43 and 6
5 is moved forward, only the first moving shoe 17 moves forward. When the first lid 9 reaches the position indicated by the chain line in FIG. 3, the rear lifting mechanism driver 65 comes into engagement with the engagement recess 75 of the swing arm 67 in the standby state.

At this time, the transfer roller 73 comes into contact with the cam convex portion 77 and restricts the clockwise rotation of the swing arm 67. As a result, the locking portion 7
1 does not come off from the engagement hole 79, and the connected state with the second moving shoe 59 is ensured. Therefore, the second movable shoe 59 is moved forward by the driver 65, and this movement causes the lifting mechanism 23 to operate and rotate the second lid 11 downward.

Simultaneously and in parallel, the lifting mechanism 23 on the first moving shoe 17 side
The first lid 9 is rotated, and each lid 9, 11 is brought into a fully closed state by 1q.

Although the structure is such that the first and second lids 9 and 11 are tilted up at the same time, only one of the lids is tilted up by 1q, and the roof opening is tilted up at the same time only when the roof is opened. It is also possible to make it face upward at the rear.

[Effects of the Invention] As described above, according to the sunroof device of the present invention, it is possible to reduce the upward rearward protrusion of the lid when the roof is opened, so that wind noise can be suppressed. Furthermore, even when the roof area is narrow like a coupe type, a large roof opening area can be secured.
