Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel opening / closing device for a sunroof which is applied to a vehicle, in particular, a vehicle such as a passenger car and which moves up and down and slides.

[0002]

2. Description of the Related Art This type of roof panel opening / closing device has brackets provided on the lower left and right sides of a panel for opening and closing an opening of a vehicle roof, and sliders provided on guide rails below the left and right sides of the opening. And a slider, a front and rear elevating mechanism for elevating and lowering the panel from the closed position to the lower position by moving the slider back and forth is provided, and the panel is configured to be able to accompany the slider in horizontal operation from the lower position to the open position.

The lowering operation of the panel from the closed position to the lowering position is configured such that the front-rear lifting mechanism simultaneously starts lowering when the rearward movement of the slider is started, and vertically lowers the panel (Japanese Patent Publication No. 58-58-58). 32046). In this way, when the panel is vertically moved up and down, the weather strips around the entire circumference of the panel come into contact with and separate from the vehicle roof at once, so this resistance is very large and an excessive load is applied to the motor that drives the slider. become. Therefore,
It is considered that the rear side of the panel is lowered in front of the front side and then the front side is lowered after the rear side of the panel is completely lowered (see Japanese Patent Laid-Open No. 5-319099).

In this latter prior art, the front lifting mechanism has a front lifting body that moves with the slider between the panel and the interlocking body to lift the panel, and a timing member is connected to the front lifting body. The interlocking body is provided with a timing cam body which engages with the guide rail when the panel moves up and down and engages with the timing member when the panel horizontally moves, and the slider is provided between the guide rail, the slider and the timing member. Position control means is provided for locking the timing member with respect to the guide rail when the rear portion of the panel is lifted and lowered through the rear lifting mechanism, and for unlocking it by the movement of the slider behind it.

In the latter prior art, the panel is moved up and down by raising and lowering the elevating body by relative movement through a cam groove and a pin provided between the elevating body and the interlocking body.

[0006]

In the latter prior art, since the front side is lowered after the rear side of the panel is completely lowered, the resistance of the weather strip on the entire circumference of the panel is reduced, and the vertical movement can be smoothly performed. . However, since the front and rear sides of the panel are raised and lowered one by one, the raising and lowering time is long, the panel tilts greatly when the rear side is completely lowered, and the front and rear lifting mechanism is located closer to the center than the front and rear ends of the panel. The height of the rear elevating mechanism is higher than that in the case of lowering vertically so that the rear end elevating stroke is larger than the elevating stroke of the rear elevating mechanism and the rear side of the panel does not contact the guide rails. Must be
Therefore, there is a problem that the total height of the panel opening / closing device becomes high. It should be noted that such a problem similarly occurs even when the front side of the panel is configured to descend before the rear side.

Further, the lifting and lowering body is supported only by engagement of the cam groove and the pin during swinging and is cantilevered, and the front and rear sliders and the interlocking body are provided so as to be movable relative to each other, which makes it difficult to take timing. There are many parts and it is difficult to assemble. An important object of the present invention is to lower the contact and separation resistance with the vehicle roof by lowering the rear side in advance when lowering the panel from the closed position and lowering the front side from the middle of the lowering. Then, there is provided a method and an apparatus for opening and closing a panel of a sunroof capable of reducing the inclination of the panel in the middle of lowering and lowering the height of the front and rear lifting mechanism.

An object of the present invention is to fix an actuating member in front of and behind the slider, pivotally connect an elevating link to a bracket fixed to the panel, and provide elevating means between the actuating member and the elevating link. It is an object of the present invention to provide a panel opening / closing device for a sunroof in which the support of the actuating member and the elevating link is strong, there is little rattling, the timing is easy, and the number of parts can be reduced.

Another object of the present invention is to guide at least one of the front and rear lifting links by holding the front part of the lifting links with both ends so that rattling of the lifting links can be eliminated and the panel can be lifted and lowered smoothly. To provide a panel opening and closing device for the sunroof. Still another object of the present invention is to form a rising wall over substantially the entire length of the slider and attach the front and rear actuating members to the outer surface of the rising wall so that the front and rear elevating mechanism such as the actuating member and the elevating link cannot be seen from the passenger compartment. (EN) Provided is a sunroof panel opening / closing device that can be used.

R) and the front side of each cam groove 17 is inclined downward.

The rear cam groove 17R for the center pin 16 has a short substantially horizontal straight line portion Ra at the rear portion, and is a downwardly arcuate arc portion Rb from this straight line portion Ra to the front end, whereas the front The cam groove 17F has a substantially horizontal straight line portion Fa longer than the straight line portion Ra from the rear end to the midway portion, and is formed in a sharp downward arcuate arc portion Fb from the straight line portion Fa to the front end.

The straight line portion Fa and the straight line portion Ra of the front and rear cam grooves 17 are portions where the middle pin 16 does not move up and down.
The portion of a that is longer than the straight line portion Ra forms the delay means 9 that does not move up and down the middle pin 16F for a longer time. still,
The horizontal distance between the front and rear ends of the front cam groove 17F and the rear cam groove 17R
And the groove height is also formed to be substantially equal.

When the front and rear actuating bodies 14 simultaneously move rearward, the front and rear cam grooves 17 start rearward movement with respect to the front and rear center pin 16, and the rear center pin 16R starts relative movement to pass through the straight line portion Ra to form an arc. As soon as it enters the section Rb, it starts descending,
It descends at a substantially constant speed until it reaches the front end of the arc portion Rb. On the other hand, even if the front cam groove 17F starts moving, the front middle pin 16F does not start descending only by moving the delay means 9 on the front side of the straight portion Fa, and the rear middle pin 16R does not move. After entering the arcuate portion Rb of 17R, it further passes through the delaying means 9 and enters the arcuate portion Fb of the front cam groove 17F, then starts descending, and descends at a high speed until the front end of the arcuate portion Fb is reached.

Therefore, when the panel 4 is moved down from the opening closing position A, the rear side is moved down first, and the rear side is in the middle of the downward movement (the state indicated by the alternate long and short dash line in FIG. 1 and the middle of the downward movement D shown in FIG. 4). Then, the front side is lowered, and the time points at which the rear side for leading down and the front side for trailing lowering reach the lowering position B are substantially the same. Even if the horizontal distance between the front and rear ends of the front and rear cam grooves 17 is different, the operation is not hindered because the longer end is not used, and the panel 4 is lowered even if the groove height is different. There is no hindrance to the movement to the open position C by only slightly inclining at the position B.

The front-rear lifting mechanism 8 has rear pins 18 (18F, 18R) at the rear portions of the front-rear lifting links 13, and rear-pin cams for slidingly guiding the rear pins 18 at the rear portions of the front and rear actuating bodies 14. The groove 19 (19F, 19R) is formed. The center line connecting the rear pin 18 and the pivot shaft 12 is located higher than the center pin 16 and the support pin 25. Rear pin 1
The rear cam groove 19R for 8 has a straight line portion that is approximately the same length as the straight line portion Ra and is substantially horizontal from the rear end to the middle portion, and is gently inclined upward from the middle portion. Further, the front cam groove 19F for the rear pin 18 has a straight line portion that is approximately the same length as the straight line portion Fa from the rear end to the midway portion and is substantially horizontal, and inclines forwardly upward from the midway portion. ing.

Therefore, when the front and rear actuating bodies 14 simultaneously move rearward, the front and rear cam grooves 19 start rearward movement with respect to the front and rear rear pins 18, and the rear rear pins 18R move in a short linear portion due to the relative movement of the cam grooves 19R. Begins to rise after passing
It rises at a substantially constant speed until it reaches the front end of the cam groove 19R. Further, the front rear pin 18F starts to rise after the cam groove 19F has passed a long straight portion due to the relative movement, and the front-rear lifting link 13 causes a seesaw swing around a support pin 25, which will be described later, and the front side lowers and the rear side rises. To do.

Therefore, the front-rear lifting link 13 has the middle pin 16
And the cam groove 17 guides up and down, the rear pin 18 and the cam groove 19 guide up and down to swing more greatly, and the panel 4 can be lifted up and down longer. The vertical height of the lifting mechanism 8 can be lowered. Incidentally, omitting the rear pin 18 and the cam groove 19,

When the rear side of the panel 4 starts to descend and the rear half of the weather strip 32 is separated from the roof 2, the panel 4 is in the state of the descending D shown in FIG. Then, in the front elevating mechanism 8F, the middle pin 16F of the front elevating means 15F passes by the delay means 9 in front of the straight portion Fa of the cam groove 17F and begins to enter the arc portion Fb, which is later than the rear elevating mechanism R. The front side of the panel 4 begins to descend.

While the rear elevating mechanism 8R slowly descends the rear side of the panel 4, the front elevating mechanism 8F rapidly descends the front side of the panel 4 in parallel, and the panel 4 moves to the closed position A. It moves to a lowering position B which is substantially parallel to and downward. When the slider 7 completes the operation of the rear elevating mechanism 8R, the operation of the front elevating mechanism 8F is also completed, and the total required time is the same as the operation time of the rear elevating mechanism 8R. The ends of the arc portions Fb and Rb of 17F and 17R are reached.

Both the front middle pin 16F and the front cam groove 17F are supported.

In the rear elevating link 13, the sliding contact body 29 provided on the side surface is in slidable contact with the guide rail 6, and the bush 50 is in contact with the front portion 14a of the rear actuating body 14R to prevent lateral movement of the elevating link 13. . Panel 4 in the lowered position B
Is further moved to the open position C by moving the slider 7 rearward, and the closing operation from the open position C reverses the opening operation.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, the delay means 9 makes the slider 7 and the front actuation body 14F relatively movable, the rear actuation body 14R is integrally moved by the rearward movement of the slider 7, and the front actuation body 14F is moved together with it slightly later. Alternatively, the shoe auxiliary body 24 and the support pin 25 are omitted, the rear pin 18 is used as a substitute for the support pin, the cam groove 19 is formed as a straight length linear groove, and the slider 7 and the front and rear actuating body 14 are integrally formed. It is possible to
