Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open roof device which is movable to a developed position for covering an upper part of a passenger compartment, a retracted position for storing a rear part of a vehicle body.

[0002]

2. Description of the Related Art As a conventional open roof device, the one shown in FIG. 8 has been proposed (Japanese Patent Publication No. 4-4167).
(See the official gazette). That is, the roof 70 is movable to a deployment position A that covers the upper portion of the vehicle compartment R as shown by the solid line and a storage position B that is stored in a storage portion 72 provided at the rear portion of the vehicle body. , A front hard roof 73 and a rear hard roof 74. Both hard roof 7
3, 74 are continuous at the unfolded position A with the inner surface facing the vehicle compartment R side, and the rear edge of the front hard roof 73 is connected to the front edge of the rear hard roof 74 via a folding mechanism 71. .

The folding mechanism 71 includes a first link 75.
And the first link 75 is connected to the bell crank 7
6, via a second link 77, it is pivotally supported by a joint bracket 78 rotatably supported by the rear hard roof 74. One end of a third link 79 is pivotally supported on the joint bracket 78, and the third link 79 is
The other end of is attached to a fixture 80 fixed to the vehicle body.

One end of a roof set bracket 81 is pivotally supported by the fixture 80, and the other end of the roof set bracket 81 is fixed to the lower end of a front hard roof 74. The roof set bracket 81 is pivotally supported by a fifth link 83 via a fourth link 82, and the fifth link 83 is driven by a drive motor 84 in the arrow direction. A gas stay 85 has one end pivotally supported by the vehicle body and the other end pivotally supported by the roof set bracket 81.

In such a structure, in order to move the roof 70 in the deployed position A to the retracted position B, the drive motor 8
When 4 is operated, the fifth link 83 rotates in the arrow direction. Then, the fourth link 82 pulls the roof set bracket 81, and the roof set bracket 81 pivots rearward about the pivot point with respect to the fixture 80. This allows
The rear hard roof 74 also rotates rearward integrally with the roof set bracket 81, and as shown in FIG. 9, the third link 79 also rotates in the same direction.

At this time, the center of rotation of the third link 79 is different from the center of rotation of the roof set bracket 81, which is the center of rotation of the rear hard roof 74, and the distance between pivot points is also different. The joint bracket 78 is rotationally driven along with the rotation. Then, the second link 77 is pulled with the rotation of the joint bracket 78, the bell crank 76 is rotated, and the first link 75 is pulled with the rotation of the bell crank 76.

As a result, the folding mechanism 71 is driven to rotate the front hard roof 73 so that the inner surface thereof faces the inner surface of the rear hard roof 74. Finally, as shown by the chain line in FIG. 9, the roof 10 reaches the storage position B accommodated in the storage portion 72 in a form in which the inner surfaces of both hard roofs 73 and 74 face each other.

[0008]

However, in such a conventional open roof apparatus as described above, when the drive motor 84 starts to operate and the fifth link 83 starts to rotate, the above-mentioned operation starts from that point. So other links 82,7
9, 77, 75, the joint bracket 78, and the bell crank 76 operate, and the folding mechanism 71 starts to be driven. Therefore, as shown in FIG. 9, the front end 73a of the front hard roof 73 is affected by the rotation of the rear hard roof 74 in the initial stage of the movement, and takes an arc locus C outside the vehicle cabin from the initial position. However, a straight line trajectory D that descends obliquely in the rear space of the passenger compartment R is taken soon.

Since the substantially linear locus D is in the vicinity of the occupant's head, when the roof 70 is moved from the deployed position A to the retracted position B, the occupant is made to feel uncomfortable. Will end up. Further, the layout of the interior parts, such as the seat back and the headrest, is required to be arranged in the front so as not to interfere with the substantially linear trajectory D. In addition to being restricted, the space inside the vehicle is restricted as a result.

Of course, by displacing the movement loci C and D further to the outside of the passenger compartment, it is possible to eliminate the pressure on the occupant, the layout of the occupant, and the restrictions on the space. However, in the above-described conventional structure, since the links 82, 79, 77, 75 and the like always operate with a constant correlation with respect to the movement of the rear hard roof 74, the movement trajectory C of the front hard roof 73, In order to change D, the design of the entire open roof device must be changed, and it is not possible to easily change the movement trajectory.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide an open roof device capable of easily changing the movement locus of the hard roof.

[0012]

In order to solve the above problems, the present invention provides a roof that is movable between a deployed position that covers an upper portion of a vehicle compartment and a storage position that is stored in a rear portion of a vehicle body. , The roof is composed of a front hard roof and a rear hard roof that are continuous with the inner surface facing the passenger compartment in the deployed position, and the rear edge of the front hard roof is folded to the front edge of the rear hard roof. Folding means is provided for connection so that the inner surface of the front hard roof is the inner surface of the rear hard roof as the rear hard roof in the deployed position pivots backward and moves to the retracted position. Link means for driving the folding means is provided so as to face the folding means, and control means for controlling the driving of the folding means by the link means is provided. Follows the rotation of the hard roof is constituted by a cam mechanism for displacing the pivot point at the proximal end of said link means.

[0013]

In the above structure, when the roof in the deployed position is moved to the retracted position, the rear hard roof rotates rearward. At this time, since the control means controls the driving of the folding means by the link means, the rotation of the rear hard roof and the movement of the front hard roof in the folding direction do not necessarily have a constant correlation. That is,
If the control means delays the movement of the rear hard roof in the folding direction with respect to the rotation of the rear hard roof, for example, even if the rear hard roof starts to rotate rearward,
The front hard roof is not folded and is connected to the front edge of the rear hard roof and rotates integrally with the rear hard roof. Therefore, the front edge of the front hard roof takes a moving path that moves away from the vehicle interior.

Further, since the control means is constituted by a cam mechanism which follows the rotation of the rear hard roof to displace the pivot point at the base end of the link means, if the shape of the cam is changed, the front portion can be changed. The movement path of the hard roof changes.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIG. 1, the roof 1 has a developed position A (shown by a solid line) that covers the upper part of the vehicle interior R and a storage position B that is stored in a storage part 2 provided at the rear of the vehicle body.
The front hard roof 3 and the rear hard roof 4 are movable with respect to each other (shown by a chain line), and both hard roofs 3 and 4 are connected to each other with the inner surface facing the vehicle compartment R side at the deployed position A. ing. The front hard roof 3 has a roof outer 5 as shown in FIG. 3, which is a sectional view taken along the line aa of FIG.
And a roof inner 6 connected to the inner surface side of the roof outer 5, and the front end of a lever 9 extending rearward of the vehicle body is fixed to the side of the roof inner 6 by nuts 7 and 7 and bolts 8 and 8. There is.

As shown in FIG. 4, the rear hard roof 4 is also composed of a roof outer 10 and a roof inner 11 joined to the inner surface of the roof outer 10. A first bracket 14 is fixed by a nut 12 and a bolt 13. The first bracket 14 is provided with a bolt 16 screwed into a nut 15, and a bush 18 is inserted in the bolt 16 to support the lever 9 in a rotatable state.

In the figure, 46 is a side window glass, 47 is a weather strip, and the pivot point of the lever 9 by the bolt 16 corresponds to the first pivot point P1 shown in FIG. Then, at the rear end portion of the lever 9 extending rearward from the first pivot point P, the first pivot point P1
The front end of the first link 20 is pivotally supported on the upper side,
A folding means is formed by the front end portion of the first link 20 and the first pivot point P.

Further, as shown in FIG. 5, the rear hard roof 4 is provided with a second rear portion behind the first bracket 13.
The bracket 21 is fixed. The second bracket 2
1, a bolt 23 screwed into a nut 22 is provided, and a bell crank 26 is rotatably supported by a bush 25 inserted in the bolt 23. A rear end portion of the first link 20 extending in the front-rear direction is pivotally supported on one protrusion 27 of the bell crank 26, and a second link extending vertically is provided on the other protrusion 28. The upper end of 29 is pivotally supported. The pivot of the bell crank 26 by the bolt 23 is the second pivot P shown in FIG.
In addition, the first and second links 20, 29 and the bell crank 26 constitute a link means corresponding to No. 2.

On the other hand, as shown in FIG. 6, a third bracket 32 is fixedly attached to the side of the storage section 2. An upper pin 56 is projectingly provided on the third bracket 32,
A roof set bracket 36 is rotatably supported by the upper pin 56, and the roof set bracket 36 is
The upper end portion of is fixed to the lower end portion of the rear hard roof 4.

Further, a lower pin 57 is provided on the third bracket 32 so as to project directly below the upper pin 56, and a cam 58 is pivotally supported on the lower pin 57. As shown in FIG. 1, a cam hole 59 is formed in the upper end of the cam 58, and a cam pin 60 planted in the roof set bracket 36 is loosely inserted in the cam hole 59. There is. Further, the lower end of the second link 29 is pivotally supported on the cam 58 by the spherical joint 16. Therefore, when the cam 58 rotates counterclockwise around the lower pin 57 in FIG. 1, the pivot point of the second link 29 moves, and the control means is achieved by the movement of the pivot point of the second link 29. To be done.

The pivot point of the roof set bracket 36 by the upper pin 60 corresponds to the third pivot point P3 shown in FIG. Also, the roof set bracket 3
As shown in FIGS. 1 and 2, the upper end of 6 is pivotally supported by the upper end of the drive link 44, and the lower end of the drive link 44 is in front of the center of the circular gear 42. It is pivoted toward the bottom edge.

In this embodiment having the above-mentioned structure, when the roof 1 in the deployed position A is moved to the storage position,
The motor 45 is operated to rotate the circular gear 42 clockwise in FIG. Then, simultaneously with the start of rotation of the circular gear 42, the lower end of the drive link 44 moves upward while drawing an arc locus (arrow a in FIG. 7). Therefore, the lower end portion of the roof set bracket 36 is attached to the drive link 44.
Is pushed up (arrow b in the figure), and the roof set bracket 36 rotates about the pivot point P3 while tilting the upper end portion rearward. As a result, the rear hard roof 4 also starts to rotate rearward integrally with the roof set bracket 36.

Further, when the roof set bracket 36 rotates clockwise about the third pivot point P3 as described above,
The cam pin 58 also rotates about the third pivot point P3 (arrow c in the figure). Therefore, the cam pin 58 makes sliding contact with the cam hole 59, and the cam 58 rotates counterclockwise around the lower pin 57, so that the lower end portion of the second link 29 moves forward.

For this reason, the bell crank 26 is left without being rotationally driven by the second link 29, and the first link 20 also maintains the state along the rear hard roof 4 almost in the same state as in the deployed position A. . Therefore, the lever 9
As a result of maintaining substantially the same state as the deployed position A, the front hard roof 3 also maintains a state of being connected to the front edge portion of the rear hard roof 4 similarly to the deployed position A. Therefore, in this state, the front hard roof 3 rotates integrally with the rear hard roof 4, whereby the front edge portion 3a of the front hard roof 3 is rotated.
Takes a locus G that goes upward from the vehicle interior R.

Then, the cam pin 60 that draws the locus of the arrow c
When reaches the foremost end of the locus, the cam pin 60 starts moving upward on the arc locus of arrow c. Therefore, when the cam pin 58 slides in the cam hole 59, the cam 58 starts rotating in the clockwise direction. As a result, the lower end of the second link 29 moves in the direction of returning to the same position as the deployed position A.

Therefore, the bell crank 26 is rotationally driven counterclockwise about the second pivot point P2 by the second link 38, and the first link 20 presses the rear end portion of the lever 9. Therefore, the lever 9 is centered around the first pivot point P1,
A rapid rotation in the counterclockwise direction is started, whereby the front hard roof 3 is folded such that the inner surface faces the inner surface of the rear hard roof 4. When the circular gear 42 rotates about 1/3, the front hard roof 3 and the rear hard roof 4 reach the storage position B stored in the storage portion 2 as shown by the chain line.

In this way, the movement locus of the front hard roof 3 that reaches the storage position B from the deployed position A corresponds to the displacement of the lower end of the second link 28, that is, the displacement of the pivot point at the base end of the link means. Dependent. Since the lower end of the second link 28 is pivotally supported by the cam 58,
When the shape of the cam hole 59 provided in the cam 58 is changed, the displacement timing of the lower end portion of the second link 28 is also changed, which changes the movement locus of the front hard roof 3. Therefore, by changing the shape of the cam hole 59, not only the locus of this embodiment shown in FIG.
The locus of movement of the front hard roof 3 can be freely set as in the locus example and the like.

[0028]

As described above, according to the present invention, the control means for controlling the driving of the folding means by the link means is provided, and the control means is adapted to follow the rotation of the rear hard roof so that the base end of the link means is provided. The cam mechanism for displacing the pivot point is used. Therefore, if the cam mechanism is changed, the displacement pattern at the base end of the link means is changed, and as a result, the movement locus of the front hard roof can be changed. Therefore, by a simple design change to change the cam mechanism, avoiding interference with interior parts such as seat backs and headrests arranged at the rear of the passenger compartment,
Alternatively, it is possible to easily and freely set the movement locus of the front hard roof in consideration of the amount of protrusion to the outside of the vehicle.
