BACKGROUND OF THE INVENTION
The present invention relates to a roof opening / closing device including a movable panel whose rear end moves up and down with respect to a roof, that is, tilts so as to open and close an opening provided in a vehicle roof.
[0002]
[Prior art]
For example, US Pat. No. 6,174,024 B1 is an example of a roof opening / closing device having a movable panel that is tilted. 7 and 8 show the configuration of this prior art roof opening and closing device. In this roof opening and closing device, the movable panel 102 is tilted by raising the rear end portion as shown in FIG. 8 from the closed state as shown in FIG. Can do. The tilt operation can be obtained by rotating the movable panel 102 around a rotation shaft 124 provided at the front lower portion thereof.
[0003]
The front end portion 121 of the movable panel 102 tends to be arranged to extend further forward of the vehicle in order to improve the appearance design of the vehicle or to increase the feeling of opening with a larger opening. However, the rotating shaft 124 of the movable panel 102 has a limit in disposing it forward due to the structure of the roof 1. For this reason, the rotating shaft 124 is disposed behind the front end 121 of the movable panel 102. In such an arrangement, the rotary shaft 124 is moved along a guide hole 142 that is inclined obliquely upward from the front to the rear formed in a member fixed to the roof 1, and the front end 121 is moved together with the tilt operation. Is configured to lift. In addition, the front end 121 does not come into contact with the roof 1 during the tilt operation, and the seal 140 is not deformed excessively. In the roof opening and closing apparatus of this embodiment, in order to slightly move the movable panel 102 rearward during the tilt operation, the link mechanism 130 disposed at the rear portion of the movable panel 102 includes a drive belt 131 and a gear device 132. A drive mechanism is provided. And it is the structure moved along the guide hole 123 formed in the support bracket 120 fixed to the movable panel 102 by the action | operation of the gear apparatus 132. FIG. When closing the movable panel 102 by the tilt operation, the movable panel 102 is lowered and moved forward in the opposite direction, and the rotary shaft 124 is moved downward along the guide hole 142 to lower the front end 121. close.
[0004]
[Problems to be solved by the invention]
Due to the flow of air when the vehicle is traveling at high speed, a large pressure is exerted on the movable panel 102 to lift the front side thereof. When the movable panel 102 is closed against such a pressure, the structure in which the front portion of the movable panel 102 is simply guided by the guide hole 142 extending obliquely upward is lowered by the force of the force pushing the movable panel 102 forward. In order to lower the movable panel 102, it is necessary to push the movable panel 102 forward with a very large force. As the size of the movable panel 102 increases, the influence of pressure increases, making it difficult to cope with it by requiring a large drive mechanism.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to realize a roof opening / closing device capable of reliably raising and lowering the front end portion of a movable panel without using a particularly large drive mechanism when the movable panel is tilted.

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a roof opening and closing device 10 according to the present invention will be described with reference to FIGS.
[0011]
As shown in FIG. 1, a roof opening and closing device 10 according to the present invention is movable so as to perform a so-called tilt operation in which a rear portion moves up and down with respect to an opening 11 provided in a roof 1 of a vehicle. Panel 2 is provided. A pair of guide rails 3 are arranged on the left and right sides of the opening 11 so as to extend in parallel in the front-rear direction. A tilt mechanism 5 (FIG. 2) is arranged to be engaged with the guide rail 3, the tilt mechanism 5 is connected to the drive device 4 by a drive cable 41, and the movable panel 2 is tilted by the operation of the drive device 4. It has become.
[0012]
As shown in FIG. 1, the roof opening and closing device 10 may be configured to further open and close the opening 11 by arranging a plurality of movable panels 2 a and 2 b behind the movable panel 2. Since the configuration of the movable panels 2a and 2b is not related to the present invention, the description thereof is omitted.
[0013]
As shown in FIG. 2, the movable panel 2 includes a panel portion 21 and a frame 21 a that is fixed to the lower surface of the panel portion 21 by bonding or the like. Further, a long fixed link 22 extending in the front-rear direction is fixed to the frame 21a with screws 22a and 22b.
[0014]
On the other hand, as shown in FIGS. 2, 3, 4, and 5, a base plate 50 is fixed to the vehicle body side, and the base plate 50 stands in order from the front of the vehicle (the left side in FIGS. 2 and 3). A support member 50 a having a front support 51, an intermediate support 52, and a rear support 53 is fixedly attached. Further, a guide rail 3 (FIG. 1) not shown in FIGS. 2 and 3 is fixed to the base plate 50.
[0015]
The front portion of the fixed link 22 is located away from the lower surface of the panel portion 21, and the rotary shaft 25 is fixed to the tip thereof. The rotary shaft 25 is provided on the front support 51 and is fitted in a long hole 51a that is inclined from the front to the rear and extends upward. When the rotary shaft 25 is guided by the elongated hole 51 a and moves backward, the rotary shaft 25 is configured to lift the front portion of the movable panel 2 relative to the roof 1. Further, the rotary shaft 25 is also engaged with a long hole 6a formed at the tip of the guide link 6 arranged to extend rearward substantially horizontally. Since the elongated hole 51a and the elongated hole 6a are formed so as to extend in directions substantially orthogonal to each other, the position of the rotary shaft 25 can be defined by two elongated holes.
[0016]
The guide link 6 is rotatably supported on the intermediate support 52 by a pivot shaft 52a at its substantially central portion. Further, a pin 6 b is attached to the rear end portion of the guide link 6. The pin 6 b is guided by being fitted into a cam hole 73 formed in the slider 7 disposed behind the guide link 6. The slider 7 is supported by a guide rail 3 (not shown in FIGS. 2 and 3) so as to be movable in the front-rear direction via shoes 71 and 72. The cam hole 73 is formed so as to incline and extend in the front-rear direction so that the front is low and the rear is high. Therefore, when the slider 7 is positioned forward as shown in FIG. 2 and the pin 6b is located at a high position of the cam hole 73, the rear portion of the guide link 6 is lifted, and the slider 7 is positioned rearward as shown in FIG. When doing so, the pin 6b is lowered and the rear part of the guide link 6 is lowered. The slider 7 is connected by a pin 91 to a connecting rod 9 that can be connected to the drive cable 41 at the rear part.
[0017]
A long hole 24 extending substantially in the front-rear direction is formed in a rear portion of the fixed link 22, and a pin 82 is movably fitted therein. A swing link 8 fixed to the pin 82 and rotatably supported by the pin 91 is disposed. A curved cam hole 81 is formed on the surface of the swing link 8 between the pin 82 and the pin 91, and a pin 53 a fixed and attached to the rear support 53 is fitted in the cam hole 81. Thus, when the pin 91 moves back and forth, the posture is defined when the swing link 8 rotates as shown in FIGS. 2 and 3.
[0018]
Next, the operation of the roof opening / closing device 10 configured as described above will be described.
[0019]
As shown in FIG. 2, when the connecting rod 9 is located at the foremost position with respect to the roof 1, the guide link 6 is most rotated counterclockwise around the pin 52 a, and the rotation axis of the movable panel 2. 25 is pushed down to the lowermost part of the long hole 51a. On the other hand, at this time, the swing link 8 is also in the state of rotating most clockwise in FIG. 2 due to the relationship between the pin 91 and the pin 53a and the cam hole 81. Then, the tilt mechanism 5 causes the movable panel 2 to be brought into contact with the edge of the opening 11 through the rotation shaft 25 and the pin 82 and the seal 40 attached to the lower surface edge of the movable panel 2 over the entire circumference. Close the opening 11. At this time, the pin 53a fits into the recess 22c formed in the fixed link 22 so that the movement of the movable panel 2 in the front-rear direction can be restricted.
[0020]
FIG. 3 shows a state where the driving device 4 is operated to move the connecting rod 9 backward from the state of FIG. 2 and the slider 7 connected to the connecting rod 9 is moved backward. And the guide link 6 will be in the state rotated most clockwise by the cam hole 73, and the rotating shaft 25 is lifted. At the same time, the swing link 8 rotates counterclockwise, and the rear part of the movable panel 2 is lifted, so-called tilt up.
[0021]
The transition from the tilt-up state in which the rear end of the movable panel 2 in FIG. 3 is raised to the state in which the movable panel 2 in FIG. 2 is closed follows the above process in reverse. As shown in FIGS. 2 and 3, the front-rear direction dimension from the upper end to the lower end of the cam hole 73 is set larger than that of the elongated hole 51a. This is because the pin 6a of the guide link 6 is guided by the long cam hole 73 and moved up and down, so that it is smaller than when the rotary shaft 25 is moved up and down directly only by the long hole 51a without using the guide link 6. It is possible with the force of direction. And even if it resists a big pressure, the movable panel 2 can be closed reliably.
[0022]
【The invention's effect】
According to the above-described configuration of the present invention, the front end portion of the movable panel is configured to be lifted via a guide link that is rotated by a slider that is connected to the driving device and moves largely in the front-rear direction, and thus is small. A large lowering force can be realized with a load in the front-rear direction. As a result, even if a large pressure is applied to the front end portion of the movable panel, the movable panel can be reliably closed.
