Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding vehicle in which a movable roof can slide between a roof opening of a fixed roof of the vehicle and a storage portion provided below the fixed roof behind the roof opening. Related to roof structure.

[0002]

2. Description of the Related Art FIGS. 13, 14 and 15 are views showing a conventional technique. As shown in FIG. 14, when the movable roof closes the roof opening, the movable roof upper surface is held substantially flush with the fixed roof upper surface, and the fixed roof faces downward from the edge of the roof opening. An extending sealing surface is provided, and a weather strip for sealing is provided on the outer periphery of the movable roof in a state of elastic contact with the sealing surface.

[0003] The sliding roof lowers the rear end of the movable roof via an elevating device from a state where the movable roof closes the roof opening, and then the movable roof moves rearward to open the roof opening. I do.

Conventionally, the width of the roof opening provided on the fixed roof is constant in the front-rear direction (that is, the vehicle center line 1b and the side opening 2c of the roof opening are parallel), or FIG. As shown in (2), the side opening 2c of the roof opening was formed such that the opening width became narrower toward the front.

When the opening width of the roof opening becomes narrower toward the front, as shown in FIG. 15, when the movable roof slides backward, as shown in FIG. A gap Q is naturally formed between the opening 2c and the opening 2c. By securing the gap Q, the movable roof can smoothly move backward without contact between the side end of the movable roof and the side opening of the roof opening. Therefore, instead of making the width of the roof opening constant before and after,
As shown in FIG. 15, the side opening 2c is designed to become narrower toward the front.

[0006]

The above prior art has the following three major problems. Explain the first problem. As shown in FIG. 13, the left and right widths of the rain rails 1 a provided on both sides of the fixed roof of the automobile are designed so that the front is widened.
The design is unbalanced with the side opening 2c of the roof opening where the opening width is constant in the front-rear direction or the opening width becomes narrower toward the front, and the appearance is extremely poor. A beautifully designed car looks distorted, ruining the overall car design.

For example, if the side of the roof opening is formed so that the width of the opening increases toward the front as shown by the two-dot chain line in FIG. 12, the side opening 2c and the rain rail 1a are formed.
Is a line that is outward facing both sides,
Both are in harmony in design, and the whole car looks beautiful.

The second problem will be described. As shown in FIG. 15, the sliding roof is usually provided with a retractable wind deflector at the front of the roof opening, but in order to prevent the occurrence of windslop noise, the wind deflector should be as wide as possible on the left and right sides. It is common to design. The fact that the width of the roof opening is constant in the front and rear or the width of the opening narrows forward as in the prior art means that the width of the wind deflector should be as wide as possible from left to right. Very inconvenient.

The third problem will be described. As shown in FIG. 14, when the sunshade and the movable roof are moved backward, the actual effective opening width M of the ceiling is determined by a wind deflector arm for supporting a retractable wind deflector, a lifting device ( Cam plate, moving body, etc.)
And the width of the roof opening N
It is narrower. That is, the opening loss P in the width direction occurs. In order to make the effective opening width M as wide as possible, the widthwise dimension of the component causing the opening loss P is designed to be as narrow as possible. How to increase the effective opening width M is an important problem that affects the commercialization of the sliding roof.

As shown in FIGS. 14 and 15, the wind deflector arm is usually provided with a side opening 2c of the roof opening.
The size of the opening loss P in the width direction is determined on the basis of the position where the wind deflector arm is provided. That is, the fact that the opening width of the roof opening is formed so as to become narrower toward the front,
This means that a window deflector arm, which is a factor that increases the opening loss P in the width direction, is provided at the narrowed portion. In the end, when the side opening 2c becomes narrower toward the front, the ceiling portion becomes smaller. This causes a disadvantage that the effective opening width M is reduced.

The present invention solves the above-mentioned problems of the prior art, and aims at improving the appearance of a roof opening and installing a retractable wind deflector having a wide left and right width. The present invention provides a sliding roof structure for an automobile, which makes it possible to increase the effective opening width of the ceiling.

[0012]

SUMMARY OF THE INVENTION In order to achieve the above object, the gist of the present invention is to provide a roof opening of a fixed roof of an automobile and a storage provided below the fixed roof behind the roof opening. In a sliding roof structure of an automobile in which a movable roof can slide between the sections, the opening width N of the roof opening is set such that the side opening 2c of the roof opening faces outward toward the front. , The front side is formed wider than the rear side, the fixed roof is provided with a sealing surface 2f extending downward from the edge of the roof opening, and the movable roof closes the roof opening on the outer periphery of the movable roof. A weather strip 4 which is in elastic contact with the sealing surface 2f in the state;
Outside the lower part of the sealing surface 2f of the side opening of the roof opening,
At least a space T that is wider than the maximum width W of the roof opening and in which the movable roof can slide back and forth is provided. From a state where the movable roof closes the roof opening, the front end of the movable roof is moved through the elevating device. Lower the rear end, then the movable roof starts sliding backwards, and when the movable roof slides,
The portion of the weather strip 4 at the movable roof side end passes outside the lower part of the sealing surface 2f of the side opening of the roof opening.

As described above, below the sealing surface 2f of the side opening of the roof opening, there is a wide space in which the movable roof can slide back and forth, and after the entire movable roof is lowered to that position, Because the movable roof slides rearward, even if the roof opening has a wider opening width on the front side than on the rear side (that is, a movable roof with a wider left and right front side than the rear side). The movable roof can move backward smoothly.

[0014]

A guide pin 6c of the moving body is inserted in the cam groove.
By moving back and forth, the rear end of the movable roof moves down and up. For example, if the moving body 6 moves rearward from the state of FIG. 5, that is, the state in which the guide pin 6c is located at the horizontal part 5e, the guide pin 6c comes to the position of the second inclined part 5f. The trailing end of 3 descends. FIG. 6 shows the lowered view. Also, if the moving body 6 moves forward from the state of FIG. 6, that is, the state in which the guide pin 6c is located at the rear end of the second inclined portion 5f, the guide pin 6c comes to the position of the horizontal part 5e, so that it is movable. The rear end of the roof 3 rises. FIG. 5 shows the ascending view. This figure 5
When the moving body 6 further moves forward from the state described above, the guide pin 6c comes to the position of the first inclined portion 5d, and the rear end of the movable roof 3 rises. FIG. 7 shows the ascending view.

The same applies to the elevation of the movable roof front end. In FIG. 5, a guide pin 6c whose outer periphery is covered with resin is provided at a front portion of the moving body 6. The guide pin 6c is fitted in a front cam groove 5a provided at a front portion of the cam plate 5. The front cam groove 5a has a horizontal portion 5e having a substantially horizontal center, a first inclined portion 5d in which a front portion of the horizontal portion 5e is inclined forward and downward, and a rear portion of the horizontal portion 5e upward and backward. And a second inclined portion 5f that is inclined.

A guide pin 6c of the moving body is inserted in the cam groove.
By moving back and forth, the front end of the movable roof moves down and up. For example, if the moving body 6 moves backward from the state of FIG. 5, that is, the state in which the guide pin 6c is located at the horizontal part 5e, the guide pin 6c comes to the position of the second inclined part 5f, so that the movable roof The front end of 3 descends. FIG. 6 shows the lowered view. In addition, the state of FIG.
That is, if the movable body 6 moves forward from the state where the guide pin 6c is located at the rear end of the second inclined portion 5f, the guide pin 6c comes to the position of the horizontal portion 5e, and the front end of the movable roof 3 rises. I do. FIG. 5 shows the ascending view.

When the moving body 6 further moves forward from the state shown in FIG. 5, the guide pin 6c comes to the position of the first inclined portion 5d. The inclination of the first inclined portion 5d is such that the height of the front end of the movable roof when the movable roof is closing the roof opening is equal to the height of the front end of the movable roof when the movable roof is tilted. The height of the front end of the movable roof 3 is maintained so that the guide pins 6
c moves to the front end of the first inclined portion 5d. FIG. 7 shows the moved view.

The order of descending the front end and the rear end of the movable roof 3 may be any of the following A to E. The above-mentioned front cam groove 5
a second inclined portion 5f of the rear cam groove 5b
It can be done freely by changing the shape of. A: The front and rear ends of the movable roof descend simultaneously. B: The rear end descends after the front end of the movable roof descends. C: The front end descends after the rear end of the movable roof descends. D: The rear end descends while maintaining the height of the front end of the movable roof, and then the front end descends to a fixed position. E: The front end descends while maintaining the height of the rear end of the movable roof, and then the rear end descends to a fixed position.

Next, the link 9 will be described. The link 9 links or does not move the moving body 6 and the movable roof 3 back and forth. The connecting link 9 is provided with guide pins 9a, 9b, 9c and a lock portion 9d. The guide pin 9a is fitted to the front guide slit 6d in the horizontal direction provided on the moving body 6 so as to be slidable in the front-rear direction. The guide pin 9b is vertically slidably fitted in a vertical guide groove 5c provided in the cam plate 5. The guide pin 9c is fitted in a rear guide slit 6e provided in the movable body 6 so as to be slidable in the front-rear direction. Most of the rear guide slit 6e is horizontal, and only the front end is bent downward. The lock portion 9d is formed so as to be immersed in the notch portion 8b provided in the guide rail 8 and to be movable back and forth in the lock groove 8c of the guide rail.

Since the lock portion 9d of the connecting link 9 in the state shown in FIG. 5 is fitted in the notch 8b of the guide rail 8, the connecting link 9 remains stationary even when the moving body 6 is moved backward. It is. Therefore, the movable roof 3 does not move backward. When the moving body 6 moves further rearward, the guide pin 9c hits a place bent below the rear guide slit 6e provided in the moving body 6, so that the guide pin 9c is pushed down. Therefore, the state where the lock portion 9d of the connecting link 9 is fitted in the cutout portion 8b of the guide rail 8 is released. FIG. 6 shows this released state.

When the moving body 6 further moves rearward from the state shown in FIG. 6, the front end wall, which is bent below the rear guide slit 6e, pushes the guide pin 9c.
The connecting link 9 moves rearward with the posture shown in FIG. At the same time, the lock portion 9d enters the lock groove 8c of the guide rail, and the upper end of the lock portion 9d moves rearward while being in contact with the lock groove upper surface 8d.

When the moving body 6 moves forward while the lock portion 9d of the connecting link is in the lock groove 8c of the guide rail, the rear portion where the movable body 6 is bent below the rear guide slit 6e. The diagonal wall pushes the guide pin 9c of the connecting link upward and diagonally forward. However, since the upper end of the lock portion 9d is in contact with the upper surface 8d of the lock groove, the connection link 9 cannot rotate upward while receiving the upward rotation force with the guide pin 9a as an axis. The link moves forward in conjunction with the moving body 6 in the same posture.

However, when the movable body 6 moves further forward and the lock portion 9d of the connecting link 9 comes to the position of the notch 8b of the guide rail 8, the lock groove upper surface 8d for restricting the upward rotation is moved. Since the connection link 9 disappears, the connection link 9 rotates upward about the guide pin 9a, and the lock portion 9d of the connection link 9 fits into the notch 8b of the guide rail 8. When the moving body 6 is further moved forward, the notch 8b of the guide rail is provided with the lock 9d of the connecting link.
Is fitted, the connecting link 9 remains stationary, only the moving body 6 moves forward, the movable roof is raised by the action of the cam, and returns to the state of FIG. Even when the moving body 6 is further moved forward from the state of FIG. 5, since the lock portion 9d of the connection link is still fitted in the notch 8b of the guide rail, the connection link 9 remains stationary. Only the moving body 6 moves forward, and the movable roof assumes a tilted posture by the action of the cam described above. The figure is FIG.

The connecting link 9 and the movable roof 3 are connected by fitting the guide pins 9b of the connecting link into the vertical guide grooves 5c provided in the cam plate 5, so that the connecting link moves forward and backward. Only when can the movable roof move back and forth as well.

FIG. 8 is a cross-sectional view taken along the line C-C of FIG. 2, and shows the relationship between the movable roof and the fixed roof at the position where the width of the movable roof is maximized while the movable roof is moving backward. Is shown. In this figure, the portion of the weather strip 4 at the movable roof side end is the sealing surface 2 at the side opening of the roof opening.
It can be seen that it has passed under the lower part of f.

Next, the wind deflector will be described. As shown in FIG. 2, a retractable wind deflector 7 and a wind deflector arm 7a for supporting the wind deflector 7 are provided around the front of the roof opening.

FIG. 9 is a sectional view taken along line DD of FIG. However, the movable roof part is omitted. The wind deflector 7 shown by a two-dot chain line is in a retracted state. Wind deflector 7 and wind deflector arm 7
a is made integrally. The wind deflector arm is provided with a spring 7b that acts to lift the wind deflector arm upward. When the wind deflector is not pressed down, the hinge pin 7 provided at the rear of the wind deflector arm
The wind deflector rotates upward by a required angle around the axis c. The wind deflector shown by the solid line in FIG. 9 is in that state.

An arm retainer 6 is provided at the front of the moving body 6 described above.
f is provided. When the moving body 6 moves forward, that is, when the arm press 6f moves forward, the arm press 6
f hits the inclined surface of the upper surface of the wind deflector arm 7a, and the wind deflector arm 7a is pressed down. Therefore, the wind deflector rotates downward around the hinge pin 7c, and the wind deflector is in the retracted state shown by the two-dot chain line. The wind deflector thus rises or becomes stowed.

FIG. 10 shows another embodiment of the seal portion according to the present invention. When the movable roof 3 closes the roof opening 2, the movable roof upper surface is held substantially flush with the fixed roof 1 upper surface, and the movable roof 3 has a peripheral wall 16 extending downward from the edge of the movable roof. The fixed roof 1 is provided with a sealing member 1
7 is attached so as to be in elastic contact with the peripheral wall 16. In addition, since the movable roof 3 of the present embodiment uses a glass plate, around the glass plate, from the end surface to the lower surface,
It has an injection-molded resin part 18, and a glass reinforcing plate 3a is inserted between the resin part and the glass plate. FIG. 11 shows the relationship between the movable roof and the fixed roof at the position where the left and right width of the movable roof is maximized while the movable roof is moving backward in this embodiment. Note that FIG.
FIG. 3 is a diagram corresponding to a cross-sectional view taken along line CC of FIG. 2. FIG.
1, it can be seen that the portion of the peripheral wall 16 at the movable roof side end passes outside the lower part of the inner periphery of the seal member 17 on both sides of the roof opening.
