DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof device having a deflector.

[0002]

2. Description of the Related Art Conventionally, a sunroof device provided on a roof of a vehicle such as an automobile prevents air from being blown into a roof opening when a panel is opened, thereby reducing noise and generating turbulence in the vehicle. To prevent this, a technique to provide a deflector near the rear edge of the roof opening (Jpn.
No. 78, hereinafter referred to as "first conventional example", and a technique of providing a deflector near the front edge of the roof opening (see Japanese Patent Publication No. 6-88499 and Japanese Utility Model Laid-Open No. 64-29017). "2nd conventional example" and "3rd conventional example" respectively
Etc.) are known.

On the other hand, a technique in which a deflector is provided for a panel to move the deflector together with the panel (Japanese Utility Model Laid-Open No. 2-105015 and Japanese Utility Model Publication No. 1-4).
No. 3933, hereinafter referred to as "fourth conventional example",
"Fifth conventional example") is also known. In any of the conventional examples, the deflector is an operating force taken out from a driving force for opening / closing or tilting the panel by a link mechanism, a cam mechanism, or the like. The position is switched to a storage position (a posture in which the inclination angle is set to be gentle or horizontal).

[0004]

In the first prior art, since the deflector is not set to the wind rectifying position unless the panel is fully opened, wind rectification cannot be performed when the panel opening is set to an intermediate value. There were drawbacks. Second,
In the third conventional example, the deflector is set to the wind rectifying position at the same time when the panel is opened. However, as the panel opening increases, the front edge of the roof opening, that is, from the deflector to the front edge of the panel. However, there is a drawback that the air flow blows into the vehicle from the distant portion.

On the other hand, in the fourth and fifth conventional examples, the deflector moves together with the panel, so that a predetermined wind rectifying action can be obtained regardless of the opening degree of the panel.
However, in the fourth conventional example, since the deflector is provided above the upper surface level of the panel, a space beyond the deflector is formed between the panel and the guide rail for guiding the movement of the panel below the panel. Was supposed to be. Therefore, there is a disadvantage that air is blown into the vehicle from this space.

The fourth prior art is limited in its application to an inner type sunroof device in which an open panel is accommodated in a lower part of a roof because of its structure. In comparison, in the case of the outer slide sunroof, the vertical distance between the panel and the guide rail is further increased, and it is meaningless to apply the technology of the fourth conventional example to the outer slide sunroof in the first place.

In the fifth conventional example, the panel includes:
A large rectangular notch is provided at the center of the front edge, and a deflector of the same size and shape is attached in this notch. For this reason, when the panel is fully closed, there is a problem in the sealing performance between the outer peripheral edge of the deflector and the inner peripheral edge of the notch, which are fitted flush in the notch. Also in the fifth conventional example, a space beyond the deflector may be formed between the panel and the guide rail below the panel, and the wind rectification function is insufficient.

The present invention has been made in view of the above circumstances, and enables a predetermined wind rectification effect by a deflector to be obtained irrespective of the degree of opening of a panel if the panel is slightly opened. A sunroof device provided with a deflector so that the wind rectification function is reliably performed over a wide range from the lower surface of the front edge portion of the panel to the guide rail, and the type of the sunroof device that can be applied is not limited. The purpose is to provide.

[0009]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, in the present invention, the deflector is provided movably with the panel. In addition, an air flow that tends to blow into the roof opening is always prevented between the lower surface of the front edge of the panel and the upper part of the guide rail. That is,
Since the deflector moves together with the panel, if the panel is slightly opened with respect to the roof opening, the deflector always exerts a wind rectification function regardless of the panel opening.

Further, since the deflector maintains the positional relationship with the lower surface of the front edge of the panel and the positional relationship with the guide rail regardless of the degree of opening of the panel, the lower surface of the panel and the upper end of the deflector are maintained. And between the lower end level of the deflector and the installation level of the guide rail. Therefore, unnecessary air is not blown into the vehicle from the roof opening.

The deflector is held by a lower pivot provided on its lower side so as to be swingable back and forth with respect to a slider or a transmission member for moving the panel back and forth, and the upper end thereof is, for example, biased by a spring. Thus, the panel may be held in contact with the lower surface of the front edge portion. The slider in this case includes not only a bracket fixed to the panel but also various brackets fixed to the shoe side in a lift mechanism or the like. The transmission member includes a drive cable, a connection component for connecting the cable to the slider, and the like. Therefore, the guide rails include those for the slider and those for the transmission member.

By providing a sliding contact member at the upper end of the deflector, when the deflector and the panel move relative to each other, it is possible to prevent the panel from being scratched or rubbing noise, and to improve the familiarity between the two to improve the wind. There is an advantage that the street can be easily prevented. The sliding member may be a roller or pad made of resin, rubber, or the like.

As a mounting structure of a deflector different from the above, an upper pivot provided on an upper side of the deflector holds the panel so as to be able to swing back and forth with respect to a lower surface of a front edge of the panel, and a lower end thereof is, for example, What is necessary is just to make it contact and hold | maintain on a guide rail by biasing a spring. In addition,
The upper pivot of the deflector may be held to be able to swing back and forth with respect to the lower surface of the front edge of the panel, and the lower pivot of the deflector may be held to be able to swing back and forth with respect to the slider.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a situation where a sunroof device 1 according to a first embodiment of the present invention is provided on a roof 2 of a one-box car type automobile (vehicle). The vehicle roof 2 is provided with a roof panel 4 which can be opened and closed by a tilting method on a front roof portion 3 corresponding to a driver's seat or a passenger seat.

The sunroof device 1 according to the present embodiment is implemented as a so-called outer slide sunroof in which a panel 7 moves back and forth from a roof opening 5 provided in an automobile roof 2 toward an upper rear portion thereof. . Therefore, the front slider 8 and the rear slider 9 are provided on the panel 7, and the front slider 8 slides along the front guide rail 10 provided inside the roof so as to sandwich both sides of the roof opening 5. It is held movably and the rear slider 9

The transmission member 24 has a flexible cable 25 and a connecting part 26 fixed at an intermediate portion of the cable 25. And, this connecting part 26
In addition, an engagement pin 27 and a projection 28 which are fitted in the vertically elongated holes 20 and 21 of the front slider 8 so as to be vertically movable are provided. The front guide rail 10 has a shoe guide groove 30 that opens in a U-shape toward the inside of the roof opening 5 and a cable guide groove 31 that opens upward inside the roof guide groove 30. The shoe 18 of the front slider 8 is fitted in the shoe guide groove 30, and the cable 25 of the transmission member 24 and a part of the connection component 26 are fitted in the cable guide groove 31.

In the front guide rail 10, the front end of the shoe guide groove 30 is inclined obliquely downward, and when the panel 7 closes the roof opening 5, the front slider 8 is pulled down. Thus, the degree of sealing and sealing of the panel 7 can be improved. The cable guide groove 31 of the front guide rail 10 extends further forward than the shoe guide groove 30. A support member 33 for the deflector 14 is slidably fitted in the cable guide groove 31 ahead of the connection component 26 of the transmission member 24. The support member 33 is connected to the connecting part 26.
Is fixed to the cable 25 of the transmission member 24 at a position separated from the transmission member 24 by a predetermined distance. Therefore, the mutual distance between the support member 33 and the connection component 26, that is, the positional relationship between the lower position of the deflector 14 and the front slider 8, is fixed to each other. The slider 8, that is, the deflector 14 and the panel 7 move together.

The deflector 14 is preferably formed of a transparent or colored transparent resin plate or the like, and a boss 35 is formed at the lower part of both ends as shown in FIGS. The boss 35 and the support member 33 are connected to the lower pivot 3 formed by an implantation pin or the like.
6 are rotatably connected to each other. Therefore,
The upper end side of the deflector 14 is swingable in the front-rear direction about the lower pivot 36.

A winding spring 37 for urging the deflector 14 forward is fitted between the support member 33 and the boss 35 of the deflector 14 around the lower pivot 36. Therefore, the state in which the upper end of the deflector 14 is in contact with the lower surface of the panel 7 is always maintained. At the upper edge of the deflector 14, a plurality of sliding members 38 are provided at a predetermined interval from each other. The sliding member 38 is attached to the lower surface of the panel 7 by the deflector 14.
In the illustrated example, the free roller is rotatable about a central axis of the deflector 14 in the longitudinal direction. The sliding contact member 38 is preferably formed of a material such as resin, rubber, or sponge that does not generate scratches or rubbing noise when in contact with the panel 7 and has good familiarity.

The slider 9 described above (see FIG. 1)
Although not shown in the figure, the bracket includes a bracket and a shoe (see FIG. 4) substantially similar to those of the front slider 8 so that the shoe moves in a shoe guide groove provided in the rear guide rail 11. Has become. The front end of the rear guide rail 11 is also inclined obliquely downward, similarly to the case of the shoe guide groove 30 (see FIG. 3) in the front guide rail 10, and the panel 7 covers the entire roof opening 5. When the closed state is set, the rear slider 9 can be pulled down to increase the degree of sealing and sealing of the panel 7.

Next, the operation status of the sunroof device 1 having the above configuration will be described. When the front slider 8 is moved rearward by the transmission member 24 from the state in which the panel 7 completely closes the roof opening 5, the front slider 8 is positioned at the front end (inclined portion) of the shoe guide groove 30 in the front guide rail 10. The shoe 18 that has been removed comes out to the rear horizontal portion. Similarly, the shoe of the rear slider 9 located at the front end (inclined portion) of the rear guide rail 11 also escapes to the horizontal portion behind it.

Therefore, the panel 7 can be pushed up obliquely rearward from the roof opening 5. At this time, since the deflector 14 receives the spring force of the coil spring 37, the upper end thereof swings upward or forward while centering on the lower pivot 36, and as a result, the front of the panel 7 The state of contact with the lower surface of the edge is maintained (see FIG. 1).

Accordingly, the deflector 14 has a rectifying function to prevent air from being blown into the vehicle from above and below the lower surface of the panel 7 and the installation level of the front guide rail 10. After that, no matter how the opening degree of the panel 7 is changed, the deflector 14 moves together with the moving panel 7, so that the above-mentioned effect can always be obtained stably.

At the time when the panel 7 is moved in the closing direction and the roof opening 5 is fully closed, the deflector 14 is operated in a substantially reverse manner to the above by the descending panel 7, that is, the upper end is pushed down. Swinging in the direction to loosen the degree of inclination. FIG. 7 relates to a sunroof device 1 according to a second embodiment of the present invention, and shows a state of attachment of a deflector 14. This second
In the embodiment, the lower pivot 36 that holds the swing of the deflector 14 is held by a support frame 40 that protrudes forward from the bracket 17 of the front slider 8 and is fixed.

With such a structure, the deflector 14
There is an advantage that the longitudinal movement of the deflector 14 is always agile and reliable, like the panel 7, because the longitudinal distance between the front slider 8 and the front slider 8 is not affected by the cutting or bending of the cable 25. In the second embodiment, the sliding contact member 38 provided at the upper end of the deflector 14 has a pad shape made of a soft resin or rubber.

FIGS. 8 and 9 show a sunroof device 1 according to a third embodiment of the present invention. In this third embodiment, the lower surface of the front edge of the panel 7 and the upper end of the deflector 14 are located at the top. The deflector 14 is connected via a pivot 43 so that the lower end of the deflector 14 is swingable in the front-rear direction. At the lower end of the deflector 14, an engaging rod 44 is provided which protrudes to both sides in the width direction. The engaging rod 44 is a front extension part 10a for forming a cable guide groove in the front guide rail 10. The upper part can be engaged.

A coil spring 45 for urging the deflector 14 downward or backward is fitted between the panel 7 and the deflector 14 around the upper pivot 43. Therefore, the lower end of the deflector 14 has the front guide rail 1.
The state in which it is brought into contact with the front extension portion 10a of the zero is always maintained. In the third embodiment, the panel 7
The deflector 14 swings about the upper pivot 43 in accordance with the back and forth movement of the front guide rail 10, and the lower end thereof is different from that of the first embodiment only in that it is kept in contact with the front guide rail 10. The basic operation and effect are the same as those of the first embodiment.

The present invention is not limited to the above embodiment. For example, in the first embodiment, the support member 33 having the lower pivot 36 of the deflector 14 is
The front guide rail 10 may be fitted into the shoe guide groove 30. Further, when the support member 33 is moved most forward with respect to the front guide rail 10 by fully closing the panel 7, the front guide is provided so as to obtain a buffering effect on the deflector 14. It is preferable to provide a damper at the corresponding position on the rail 10 or at the front of the support member 33.

In the first and second embodiments, the panel 7
A guide rail that guides the upper end of the deflector 14 to move back and forth may be provided on the lower surface of the front edge portion. Third
In the embodiment, the position at which the engaging rod 44 provided at the lower end of the deflector 14 abuts on the front guide rail 10 is not limited to the upper surface of the rail, and, for example, when the front guide rail 10 is provided with a lateral groove or the like. May be fitted into this lateral groove.

The point that the guide rail is divided into the front part (10) and the rear part (11), and the groove structure of the guide rails (10, 11) are not limited at all. . The present invention is not limited to the application to the outer slide sunroof, but includes a tilt inner slider system for moving the panel 7 backward after tilting down, a tilt outer slider system for moving the panel 7 backward after tilting up, and a hood (canvas top). The present invention can be applied to any type of sunroof device such as a method. Also, the present invention can be applied to a manual sunroof device.

[0032]

As is apparent from the above description, in the sunroof apparatus according to the present invention, the deflector is movable together with the panel, and the deflector is always moved between the lower surface of the front edge of the panel and the upper part of the guide rail. This prevents the air from trying to blow into the roof opening, so if the panel is slightly open with respect to the roof opening, the deflector will always keep the wind regardless of the panel opening. Not only a rectifying action is obtained, but also no unnecessary space is created between the lower surface of the panel and the upper end of the deflector, and between the lower end level of the deflector and the installation level of the guide rail, and therefore, the roof opening Unnecessary air is not blown into the vehicle from the inside.

Therefore, noise reduction in the vehicle can be reliably obtained. The deflector can be configured to swing back and forth around the lower pivot, or it can swing back and forth around the upper pivot.In both cases, there is no need to provide a link mechanism or cam mechanism, so the structure is simplified. In addition, it is possible to suppress failures, reduce costs, and the like.

When the deflector swings back and forth about the lower pivot, and a sliding contact member is provided at its upper end, the deflector and the panel may be damaged when the panel relatively moves. In addition to this, there is an advantage that both noise and rubbing noise can be prevented, and the familiarity between the two can be improved to easily prevent the passage of wind.
