[Purpose of the invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof for a vehicle, and more particularly to a driving device for a roof panel for opening and closing an opening.

[0003]

2. Description of the Related Art Conventionally, as a driving apparatus of this kind, a driving apparatus disclosed in Japanese Patent Application Laid-Open No. 62-2419 is known. This has a driving means and a cable which is linked to the roof panel by a gear mechanism comprising a plurality of gears and which is connected to the driving means. The roof panel is opened and closed by pushing and pulling the cable.

[0004]

However, in the deflector device described above, the impact force due to the operation of the driving means is directly transmitted to the cable via the gear mechanism together with the driving force. As a result, the transmitted impact force adversely affects the operation of the cable, and also deteriorates the durability of the gear mechanism.

Therefore, an object of the present invention is to provide a simple structure capable of effectively absorbing an impact force caused by operation of a driving means in a transmission path of the driving force.

[0006]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, an opening 2 is formed in a vehicle roof 1. A housing 3 is fixedly provided on the vehicle roof 1 around the periphery of the opening 2. The housing 3 has a substantially U-shape along the front edge and both side edges of the opening 2. Guide rails 3a are formed on both sides of the opening 2 along the side edges thereof. On the guide rail 3a, a roof panel 5 for opening and closing the opening 2 via a link mechanism 4 is provided. It is slidably supported. A drive device 6 is provided at a portion of the housing 3 located at the front edge of the opening 2, and the drive device 6 is linked to the link mechanism 4 via a cable 8 (shown in FIG. 2). In addition, a deflector device 7 is provided at a front edge of the opening 2 so as to be in a protruding state or a retracted state in conjunction with the sliding of the roof panel 5.

The driving device 6 will be described.

As shown in FIG. 2 and FIG.
, A cylindrical rotary shaft 10 is rotatably supported by upper and lower walls thereof. A second gear 11 is supported by the rotating shaft 10 so as to rotate integrally therewith.
2, and is meshed with the output gear 13. The output gear 13 is supported so as to rotate integrally with an output shaft 14 rotatably supported on the upper and lower walls of the case 9, and the tip of the output shaft 14 projects outward from the case 9 to extend the cable 8.
The pinion gear 15 meshed with is supported so as to rotate integrally. The intermediate gear 13 is supported by an intermediate shaft 16 rotatably supported on upper and lower walls of the case 9.

A sleeve 17 is supported on the rotating shaft 10 so as to rotate integrally or relatively through a manually operated clutch mechanism 18 described later. The first gear 18 is supported around the boss 17 a of the sleeve 17 so as to rotate relative to the rotation shaft 10 and to rotate integrally with the sleeve 17. A worm gear 20 fixed to a rotating shaft 19 of the motor meshes with the first gear 18. The first gear 18 has a plurality of engagement holes 21 and a notch 22. The flange portion 17 b of the sleeve 17 is located in the cutout portion 22, and has a plurality of protrusions 23 inserted into the engagement holes 21. This engagement hole 2
Rubber materials 24 are disposed around the protruding portions 23 in each of them. The motor, the first gear 18, the sleeve 17, the second gear 11, the intermediate gear 12, and the output gear 13 are all housed in the case 9.

The manually operated clutch mechanism is a key 2
5, a manual operation shaft 26 and a spring 27. The manual operation shaft 26 is supported in the rotary shaft 10 so as to be vertically movable along the axial direction. The key 25 is fixed to the manual operation shaft 26, penetrates a vertically extending long groove 10 a formed on the rotary shaft 10, and is engageable with an engagement groove 17 c formed on the sleeve 17. The spring 27 is disposed between the rotary shaft 10 and the manual operation shaft 26, and the manual operation shaft 26 receives the urging force of the spring 27, and is always in the downward direction, that is, the engagement groove 17c and the key 25.
Are always urged in the direction of engagement.

The tip of the rotating shaft 10 projects outward from the case 9, and a detecting mechanism 28 for detecting the position of the roof panel 5 from the rotation angle of the rotating shaft 10 is provided at the tip. The detection mechanism 28 is covered by a cover 29 fixed to the case 9 and is housed between the case 9 and the cover 29.

Next, the operation of the present invention will be described.

When the motor is operated to rotate the rotating shaft 19 in the closed state of the opening 2, the worm gear 2
The first gear 18 rotates through the zero. This first gear 18
Due to the rotation of, the engagement hole 21 and the projection 23 are engaged via the rubber material 24, and the rotation of the first gear 18 is transmitted to the sleeve 17 to rotate the sleeve 17. By the rotation of the sleeve 17, the rotation is transmitted to the rotary shaft 10 via the key 25, and the rotary shaft 10 is rotated.
Gear 11, intermediate gear 12, output gear 13, and output shaft 14
, And finally the pinion gear 15 rotates.
The rotation of the pinion gear 15 pushes and pulls the cable 8, whereby the roof panel 5 slides via the link mechanism 4. As a result, the opening 2 changes from the closed state to the open state. By operating the motor to rotate the rotation shaft 19 in the opposite manner to the above, the roof panel 5 is rotated.
Slides in the opposite direction to that described above to change the opening 2 from the open state to the closed state. If the roof panel 5 does not slide due to a failure of the motor or the like, the manual operation shaft 26 is moved up against the urging force of the spring 27 to engage the key 25 with the engagement groove 17c. Is released, and the rotating shaft 10 is rotated without rotating the sleeve 17 by rotating the manual operation shaft 26 in this state, whereby the roof panel 5 can be slid.

As described above, the rotation of the first gear 18 is transmitted to the sleeve 17 by the engagement between the engagement hole 21 and the projection 23 via the rubber material 24. Therefore, the impact force due to the operation of the motor is absorbed by the rubber material 24, and only the driving force is transmitted from the first gear 18 to the sleeve 17. Thus, the cable 8 is actuated by the impact force of the motor operation.
Is not adversely affected, and the durability of the second gear 11, the intermediate gear 12, and the output gear 13 is not deteriorated. The rubber member 24 is disposed in the engagement hole 21 of the first gear 11 and the sleeve 17 is provided with the notch 2 of the first gear 11.
2 located within. That is, the rubber member 24 and the sleeve 17 are disposed within the thickness of the first gear 11. Thus, the impact force due to the operation of the motor can be absorbed in a small space without increasing the size in the axial direction.
