[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sunroof device, and more particularly to a sunroof device that can reliably prevent a mechanism from being damaged due to foreign matter being caught.
[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 with the opening closed, the slide storage position stored in the roof behind the opening with the opening open, and the rear end opened before reaching the slide storage state Further, a tilt-up position in which the rear end is raised from the opening is set before or after the fully closed position.
[0003]
In the case of this type of sunroof device, when a foreign object is sandwiched between the front end of the lid and the front edge of the opening, the lid is reversed backward to prevent damage to the mechanism. This reversal of the lid backward is reversed largely (about 150 mm) in order to facilitate the removal of foreign matter.
[0004]
[Problems to be solved by the invention]
However, in such a conventional technique, when a foreign object is sandwiched between the front edge of the lid and the front edge of the opening, the structure is largely reversed backward, but after the lid The structure is not reversed when a foreign object is sandwiched between the end and the rear edge of the opening. Therefore, it is desired to realize an inversion structure on the rear end side of the lid, but the inversion structure on the front end side of the lid as described above cannot be used as it is. This is because, in the case of the rear end of the lid, there is a case where a foreign object is sandwiched by descending from the upper edge of the opening, and in such a case, as in the case of the front end of the lid, the amount of reversal of the lid is increased. If secured, the movement stroke of the lid to the front side is shorter than that of the rear side, so that the lid once rises and then descends again to pinch foreign matter, increasing the damage to the mechanism.
[0005]
The present invention has been made paying attention to such a conventional technique, and when a foreign object is sandwiched between the rear end of the lid and the rear edge of the opening, the lid is appropriately reversed to The sunroof device which can prevent damage of a certainty is provided.

The stopper 13 has a pair of front and rear inclined walls 14, 15 inclined rearward. The lower end of the front inclined wall 14 closes the groove 10, and the rear inclined wall 15 opens the groove 10. Yes.
[0022]
A motor 16 as a “drive unit” is provided in the center of the front rail 5 located on the front side which is “one side” of the opening 2. A cable 17 (FIGS. 6 to 9) is routed from the motor 16 to each side rail 3. One end of the cable 17 is protected by a guide pipe 18 (FIG. 1), reaches from the motor 16 to the corner member 4, and passes through the inward groove portion 10 of the side rail 3. The other end of the cable 17 extends from the motor 16 to the lower side of the flange 6 of the side rail 3 while being protected by the guide pipe 18. Each cable 17 is engaged with a gear of the motor 16 and is sent out in the front-rear direction according to the rotation direction of the motor 16.
[0023]
The side rail 3 is provided with a slider 19 and a hook 20 that move forward and backward together with the cable 17 while being connected to the cable 17. As shown in FIGS. 8 and 9, the slider 19 and the hook 20 move back and forth with both ends engaged in the pair of grooves 9 and 10. A guide pin 21 that protrudes outward is provided at the upper end of the slider 19, and an engaging portion 22 that opens forward is recessed in the front surface of the hook 20.
[0024]
On the other hand, guide members 24 along the front-rear direction are fixed to the lower surfaces of the left and right ends of the lid 23 provided in the opening 2. The guide member 24 is formed with a notched guide groove 25 having a generally inverted “height” shape. A cap member 26 (not shown in FIGS. 2 to 5) having a U-shaped cross section that opens outward is attached to the guide groove 25. The cap member 26 is a molded product insert-molded with respect to the guide member 24, and the upper and lower end portions sandwich the edge portion of the guide groove 25. The guide pin 21 provided at the upper end of the slider 19 is engaged with the guide groove 25 from the inside with the cap member 26 interposed therebetween, and is movable within the guide groove 25.
[0025]
A front leg 27 is formed at the front end of the guide member 24, and the lower end of the front leg 27 is engaged with the outward groove 9 as shown in FIG. The lower end of the front leg portion 27 has an elliptical cross section, and is movable along the groove portion 9 and can also rotate (angle change) within the groove portion 9.
[0026]
Further, an intermediate leg portion 28 that moves up and down between the inclined walls 14 and 15 before and after the stopper 13 fixed to the side rail 3 is formed at an intermediate position of the guide member 24. The movement of the intermediate leg portion 28 in the front-rear direction is restricted only by moving the lower end of the intermediate leg portion 28 obliquely in the up-down direction along the inclined walls 14, 15.
[0027]
Further, a rear leg 29 is formed at the rear end of the guide member 24. The rear leg portion 29 is engaged with the engaging portion 22 of the hook 20 in the fully closed position at the lower end, and the vertical movement is restricted.
[0028]
Next, the operation of the lid 23 will be described in order. First, in the fully closed position (FIG. 2), the guide pin 21 of the slider 19 is in contact with the front end of the guide groove 25, and the opening 2 is completely closed by the lid 23. Further, the lower end of the rear leg portion 29 engages with the engaging portion 22 of the hook 20. The guide pin 21 is in contact with the front end of the guide groove 25, the rear leg portion 29 is engaged with the hook 20, and the intermediate leg portion 28 is located in the stopper 13, so that the lid 23 is in the front-rear direction and the vertical direction. The backlash is prevented.
[0029]
Next, when the motor 16 is rotated and the cable 17 is sent to the rear side, the slider 19 and the hook 20 move backward. When the guide pin 21 comes to an intermediate position of the guide groove 25, the rear end of the lid 23 rises around the lower end of the front leg portion 27 of the guide member 24 to reach a tilt-up position (FIG. 3).
[0030]
Further, when the slider 19 is moved rearward and the guide pin 21 is brought into contact with the rear end of the guide groove 25, the lid 23 is in a flap position (FIG. 4) with the rear end lower than the opening 2. When the flap position is reached, the lower end of the intermediate leg portion 28 is located below the rear inclined wall 15 and can move rearward. Therefore, when the slider 19 is further retracted from this state, the guide pin 21 is moved into the guide groove 25. The lid 23 slides into the roof 1 behind the opening 2 while being in contact with the rear end, so that the slide storage position (FIG. 5) is reached. At the slide storage position, the front end of the lid 23 is also slightly lowered so as not to interfere with the rear edge of the opening 2.
[0031]
Then, as shown in FIG. 10, in order to return the slide storage position to the original fully closed position, the motor 16 may be reversed to move the slider 19 forward. The guide pin 21 moves while engaging with the rear end of the guide groove 25 until the flap position. When the flap position is reached, there is nothing to hold the rear end of the lid 23 from above, so that the guide pin 21 moves forward in the guide groove 25 and returns to the fully closed position after passing through the tilt-up position.
[0032]
In this embodiment, the fully closed position is at the front end of the guide groove 25, and the tilt-up position and the flap position are in order behind the guide groove 25. Therefore, as described above, the rear of the lid 23 is reached from the tilt-up position to the flap position. The end approaches the rear edge of the opening 2 from above, passes through the rear edge to become a flap position, and then becomes a slide storage position. Therefore, when the rear end of the lid 23 is lowered, there is a possibility that foreign matter (such as a brush for car wash) X as shown in FIG.
[0033]
However, in this embodiment, even if the foreign matter X is sandwiched between the rear end of the lid 23 and the rear edge of the opening 2, the rear end of the lid 23 immediately rises and reverses to stop at the tilt-up position. It has become. Therefore, the lid 23 once raised does not return to the fully closed position and returns again, and the foreign matter is not pinched twice, so that the mechanism can be reliably prevented from being damaged.
[0034]
In the case of such a lid 23, there are two forms for sandwiching the foreign matter X. One is when the foreign object X is sandwiched between the front end of the lid 23 and the front edge of the opening 2, and the other is between the rear end of the lid 23 and the rear edge of the opening 2 as described above. This is a case where the foreign object X is sandwiched. In the case of pinching at the front end, in order to easily remove the foreign matter X, it is largely reversed backward. In the case of pinching at the rear end, as described above, it is lifted and reversed to stop at the tilt-up position. Recognition of these two pinchings is performed by detecting the position of the lid 23 by the motor 16.
[0035]
That is, the motor 16 can detect the position of the lid 23 based on the count number with the fully closed position as a reference point, and can also detect the trapping of the foreign matter X due to an increase in load (current / voltage) applied to the motor 16. Yes. Therefore, the pinching at the rear end of the lid 23 can be recognized separately from the pinching at the front end.
[0036]
In order to detect the pinching at the rear end of the lid 23, a touch type or pressure type sensor S as shown in FIG. 11 is provided at the rear edge of the opening 2, and the foreign object X is detected by the sensor S. Then, an inversion signal may be output to the motor 16.
[0037]
In the above embodiment, the type having the fully closed position at the front end of the guide groove is taken as an example, but the fully closed position is in the middle of the guide groove, the tilt-up position is on the front side, and the flap position is on the rear side. Such a type may be used.
[0038]
【The invention's effect】
According to the present invention, the fully closed position is at the front end, and the tilt up position and the flap position are in order behind the fully closed position. Therefore, the rear end of the lid is at the rear edge of the opening between the tilt up position and the flap position. It approaches from the upper side, passes the rear edge, and becomes a flap position. Even if a foreign object is caught when the rear end of the lid passes through the rear edge of the opening, the rear end of the lid immediately rises and reverses and stops at a tilt-up position away from the rear edge of the opening. Surely prevented. In addition, in the type in which the fully closed position is at the front end in this way, the guide pin of the slider is in contact with the front end of the guide groove and is stopped, so that rattling of the lid can be suppressed.
