Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sunroof device, and more particularly to a sunroof device provided with a shade below a lid.
[0002]
[Prior art]
As a sunroof device of an automobile, a lid that moves back and forth is provided in an opening formed in the roof, and the opening is opened and closed by this lid (refer to Japanese Utility Model Publication No. 8-5852 as a similar technique). As the form of the lid moving back and forth, the fully closed position that closes the opening, the fully open position that is housed in the roof behind the opening and the opening is opened, and the tilt up with the rear end raised above the opening There is a position. Conventionally, the fully closed position is in the middle of the forward / backward movement range of the slider, and when the slider moves to the front side, it reaches the tilt-up position, and when it moves to the rear side, it reaches the fully open position.
[0003]
[Problems to be solved by the invention]
However, in such a conventional technique, the fully closed position of the lid, which requires the most strict position in the front-rear direction to ensure water tightness and prevent wind noise, is moved forward and backward. Since it was set in the middle of the range, it was difficult to obtain a stable state of the lid, and high accuracy and rigidity were required for holding the position of the lid. In other words, the center position of the lid in the forward / backward movement range is an unstable position that can move both on the front side and the rear side, so a position holding mechanism in both directions is required, and it has high accuracy and rigidity. And the structure becomes complicated.
[0004]
Therefore, a new structure is conceivable in which the fully closed position is changed to the front end in the forward / backward movement range of the lid, the tilt up position is provided at the center, and the fully open position is provided at the rear end. In this way, a stable position holding state in the front-rear direction of the lid can be obtained simply by abutting the lid against the front end of the opening.
[0005]
In the conventional sunroof device, there is a fully closed position of the lid in the middle of the front and rear positions of the slider that controls the lid. In the structure in which the lid is tilted up by moving the slider forward from this fully closed position, the slider that tilts up The forward movement of the shade and the backward movement direction of the shade are opposite, so if you want to open the shade in conjunction with the slider and ventilate automatically at the tilt up position, It is difficult to interlock the opening of the shade, and there is a problem that the structure becomes extremely complicated even if interlocking is possible.
[0006]
In view of such a situation, in the novel type sunroof device as described above, the slider moves in the downward direction of the lid when the lid is moved from the fully closed position to the tilt-up position. Provided a sunroof device that can open the shade in conjunction with the movement of the lid when the lid is moved from the fully closed position to the tilt-up position by paying attention to the movement in the same direction to match the opening direction of the provided shade Is.
[0007]
[Means for Solving the Problems]
According to the first aspect of the present invention, a lid is provided in an opening formed in the roof of the vehicle body so as to be movable back and forth so as to be able to cover the opening; A guide member having guide grooves of a predetermined shape on both sides, and a shade provided inside the guide member and below the lid and movably back and forth so as to cover the opening Side rails are arranged on both the left and right sides of the opening, and a cable that moves back and forth by driving means is arranged on the side rail, and a slider connected to the cable can be moved back and forth. The slider is formed with a guide pin engaged with the slider so that the guide member can freely move in the guide groove. When the guide pin is in contact with the front end of the guide groove by moving in the id groove, the fully closed position where the opening is blocked by the lid, and the lowest position where the guide pin is provided in the middle of the guide groove. By engaging the position, the lid rotates about the front end and the rear end rises above the opening, and the lid with the guide pin in contact with the rear end of the guide groove A sunroof device capable of obtaining a flap position in which a rear end portion of the shade descends below the opening and a fully open position in which the lid slides rearward through the flap position so that the opening is opened. The part is provided with a convex part, and the side rail is provided with an auxiliary slider which moves back and forth while being connected to the cable. A lever that is in contact with the bottom surface of the rail and that has an engaging portion that can be engaged with the convex portion at the upper end is pivotally supported, and the interlocking range from the fully closed position of the lid to the substantially tilted position on the bottom surface of the side rail An operating part is formed, and when the lever contacts the operating part, the engaging part of the lever can be engaged with the convex part, and when the lever contacts the bottom surface outside the interlocking range, the lever is engaged. The portion cannot be engaged with the convex portion.
[0008]
According to the first aspect of the present invention, the engaging portion formed on the lever is engaged with the convex portion of the shade only in the interlocking range from the fully closed position of the lid to the substantially tilted position, and thus corresponds to the interlocking range. The shade will open as much as the stroke to perform, and the necessary ventilation at the tilt-up position can be performed. When the interlocking range is exceeded, the engagement between the engaging portion and the convex portion is released, and only the lid moves by a necessary stroke with respect to the shade, and the shade remains held.
[0009]
According to the second aspect of the present invention, after the auxiliary slider exceeds the interlocking range, a part of the lid comes into contact with the rising portion formed at the rear end of the shade, and the shade and the lid align the front end portions of each other. It reaches the fully open position in the state.
[0010]
According to the second aspect of the present invention, after the auxiliary slider exceeds the interlocking range, a part of the lid comes into contact with the rising portion formed at the rear end of the shade, and the shade and the lid move the front end of each other. Since it reaches the fully open position in the aligned state, it is not necessary to manually open the shade after exceeding the interlocking range, and the shade is stored neatly without being left behind.
[0011]
According to a third aspect of the present invention, another convex portion is formed at a position offset in the left-right direction from the convex portion of the shade, and the lid bracket is fixed to the lid, and the lid is closed with respect to the other convex portion. A latch that only engages was formed.
[0012]
According to the third aspect of the present invention, when the lid is moved in the closing direction, the latch engages with another convex portion formed on the shade, and the shade reaches the vicinity of the flap position together with the lid. Since the latch does not engage with another convex portion in the opening direction of the lid, the latch does not affect the engagement relationship between the convex portion and the lever engaging portion in the interlocking range.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of the present invention will be described below with reference to FIGS. Note that FIGS. 5 to 8 show the respective components through for convenience of explanation.
[0014]
A sunroof opening 2 is formed in the roof 1 of the automobile. A lid 3 is provided in the opening 2 so as to be movable back and forth so that the opening 2 can be opened and closed. A shade 4 is provided on the lower side of the lid 3 so as to be movable back and forth so as to block the sunlight inserted from the opening 2. Side rails 5 of extrusion-molded products formed symmetrically on the left and right sides of the opening 2 and below the roof 1 are respectively arranged. A motor 6 as “driving means” is provided at the front of the opening 2. Cables 7 (FIGS. 9 and 10) are routed from the motor 6 into the left and right side rails 5 respectively. The cable 7 is engaged with a gear of the motor 6 and can move in the front-rear direction simultaneously with the left and right according to the rotation of the motor 6.
[0015]
The side rail 5 is provided with a slider 8, an auxiliary slider 9, and a hook 10 that move forward and backward together with the cable 7 while being connected to the cable 7. A guide pin 11 is provided at the upper end of the slider 8.
[0016]
A rear end of the lever 12 is rotatably supported on the auxiliary slider 9. The downward projection 12b provided in the middle of the lever 12 is biased downward by the spring 12a (FIG. 2) and is in contact with the bottom surface of the side rail 5. A laterally engaging portion 13 is formed at the upper end of the lever 12.
[0017]
On the other hand, guide members 14 extending in the front-rear direction are fixed to the bottom surfaces of the left and right ends of the lid 3 provided in the opening 2 so as to move back and forth integrally with the lid 3. The guide member 14 can be pivoted up and down about a front leg (front end) 15 that is slidably engaged with the side rail 5 in the front-rear direction. It is detachable from the front side. A lid bracket 17 is provided near the guide member 14, and the lid bracket 17 is also fixed to the lid 3.
[0018]
A resin cap member 18 is fitted into the guide member 14 at the center thereof. The cap member 18 is provided with a guide groove 19 having a substantially inverted “height” shape when viewed from the side (in the state of FIG. 3) in a non-through state. A guide pin 11 formed at the upper end of the slider 8 is movably engaged with the guide groove 19. In this manner, if the guide groove 19 is formed in the resin cap member 18, processing is easier than the case where it is directly formed in the metal guide member 14. Further, since the guide pin 11 comes into contact with the resin, there is little sliding resistance, and the guide pin 11 moves smoothly. Furthermore, since the guide groove 19 of the cap member 18 is not penetrating, the rigidity of the cap member 18 is not reduced.
[0019]
On the other hand, the left and right end portions of the shade 4 are located inside the guide member 14, and a convex portion 20 is formed on the upper surface of the left and right end portions, and on the inner side on the front side of the convex portion 20. Another convex portion 21 is integrally formed at the offset position. In addition, a rising portion 22 is formed at the rear end of the shade 4, and the lid 3 is connected to a drain 23 that moves back and forth in conjunction with the lid 3 at the rear end of the lid 3. A predetermined interval (stroke difference) S for aligning the front ends of the shades 4 is secured. The convex portion 20 and the other convex portion 21 may be formed as a single resin block or may be separate.
[0020]
A part of the bottom surface of the side rail 5 has a partially low interlocking range R (FIG. 3) that is an “actuating part”. The interlocking range R corresponds to a range from a fully closed position of the lid 3 described later to a tilt up position. When the lower end protrusion 12b of the lever 12 abuts on the interlocking range R, the engaging portion 13 of the lever 12 has a height that can engage with the convex portion 20 (the same height as the convex portion 20), and the interlocking range. When it contacts the bottom surface other than R, it becomes a height (above the convex portion 20) that cannot be engaged with the convex portion 20.
[0021]
On the lower surface of the lid bracket 17 located on the upper side of the shade 4, a latch 25 urged downward by a spring 24 is supported in an obliquely forward state. The latch 25 is formed at the left and right positions corresponding to the other convex portion 21 and engages with the other convex portion 21 only when the lid 3 is moved in the closing direction (forward). In the opening direction, the latch 25 is lifted upward against the spring 24 and does not engage with the other protrusion 21.
[0022]
Next, the actual way of movement of the lid 3 and the shade 4 will be described with reference to FIGS.
[0023]
First, when the driving force of the motor 6 is transmitted to the slider 8 via the cable 7 from the fully closed state (FIG. 5) and the slider 8 is retracted, the guide pin 11 of the slider 8 is moved to the front end portion of the guide groove 19. The lid 3 reaches the middle part and reaches the tilt-up position (FIG. 6). At this time, since the lever 12 is in contact with the low interlocking range R, the engaging portion 13 of the lever 12 is engaged with the convex portion 20 of the shade 4, and the shade 4 is also interlocked with the lid 3 for ventilation. Open only the necessary interval K (FIG. 6).
[0024]
Next, when the slider 8 is further retracted, the guide pin 11 reaches the rear end portion through the intermediate portion of the guide groove 19, and the lid 3 is in the flap position where the rear end is lowered below the opening 2 (FIG. 7). . At this time, in the range beyond the tilt-up position, the interlocking range R ends, and the lever 12 comes into contact with the general surface of the bottom surface of the side rail 5, so that the engaging portion 13 of the lever 12 is lifted upward, and the convex portion The engagement with 20 is released, and there is no further opening operation of the shade 4.
[0025]
When the slider 8 is retracted while the guide pin 11 is engaged with the rear end portion of the guide groove 19, the lid 3 is fully opened with the opening 2 fully opened (FIG. 8 shows a state immediately before full opening). ing). Before reaching the fully open position, the drain 23 at the rear end of the lid 3 moves a predetermined distance S (FIG. 5) and then pushes the rising portion 22 at the rear end of the shade 4. Together they are fully open. Since a predetermined interval (stroke difference) S is ensured between the lid 3 and the shade 4, the front end of the lid 3 and the shade 4 are aligned as shown in FIG. 8 in the fully opened state. Become.
[0026]
When the lid 3 is moved in the closing direction from the fully open position, the latch 25 engages with another convex portion 21 of the shade 4, and the shade 4 moves in the closing direction together with the lid 3, and both of them reach the vicinity of the flap position. Accompany.
[0027]
【The invention's effect】
According to this invention, since the engaging portion formed on the lever engages with the convex portion of the shade only in the interlocking range from the fully closed position of the lid to the substantially tilt-up position, only the stroke corresponding to the interlocking range is obtained. The shade opens and provides the necessary ventilation at the tilt up position. When the interlocking range is exceeded, the engagement between the engaging portion and the convex portion is released, and only the lid moves by a necessary stroke with respect to the shade.
