【Example】

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

0010 As shown in FIG. 1, an opening 2 is formed in a vehicle roof 1. As shown in FIG. this opening A housing 3 is fixed to the vehicle roof 1 and arranged around the periphery of the portion 2. This ha The housing 3 has a substantially U-shape along the front edge and both side edges of the opening 2. opening Guide rails 3a are formed along both side edges of the portion 2. The opening 2 is opened and closed via the link mechanism 4 in the guide rail 3a. A roof panel 5 is slidably supported. In front of opening 2 of housing 3 A drive device 6 is disposed in a portion located at the edge, and this drive device 6 is connected to a cable. It is linked to the link mechanism 4 via a link 8 (shown in FIG. 2). Also, the front edge of the opening 2 is a deflector that is in a protruding or retracted state in conjunction with the sliding of the roof panel 5. A data storage device 7 is provided.

[0011] The drive device 6 will be explained.

0012 As shown in FIGS. 2 and 3, the case 9 has a cylindrical rotating shaft 10 on its upper and lower walls. It is rotatably supported. A second gear 11 rotates integrally with this rotating shaft 10. The second gear 11 meshes with the output gear 13 via the intermediate gear 12. are combined. This output gear 13 is rotatably supported by the upper and lower walls of the case 9. The output shaft 14 is supported so as to rotate integrally with the output shaft 14, and the tip of the output shaft 14 is connected to the case. The pinion gear 15 protruding outward from the cable 8 and meshing with the cable 8 is integrally rotated. I support it as such. Note that the intermediate gear 13 is rotatably supported on the upper and lower walls of the case 9. The intermediate shaft 16 is supported by an intermediate shaft 16.

[0013] A sleeve 17 is connected to the rotating shaft 10 via a manually operated clutch mechanism 18, which will be described later. They are supported to rotate together or relative to each other. Boss of this sleeve 17 The first gear 18 is arranged around the portion 17a so as to rotate relative to the rotating shaft 10 and to rotate It is supported so as to rotate integrally with the rib 17. This first gear 18 has A worm gear 20 fixed to the rotating shaft 19 of the motor is meshed with it. 1st gear A plurality of engagement holes 21 and notches 22 are formed in 18. The flap of sleeve 17 The flange portion 17b is located within the cutout portion 22 and has a plurality of protrusions inserted into the engagement hole 21. A portion 23 is formed. Rubber material 24 is provided around the protrusion 23 in the engagement hole 21, respectively. is installed. These, motor, first gear 18, sleeve 17, second gear 1 1, the intermediate gear 12 and the output gear 13 are all housed within the case 9.

[0014] The manually operated clutch mechanism includes a key 25, a manual operating shaft 26, and a spring 2. It consists of 7. The manual operation shaft 26 is disposed within the rotating shaft 10 along its axial direction. It is supported so that it can move up and down. The key 25 is fixed to this manual operation shaft 26. , into the sleeve 17 by passing through the long groove 10a formed in the rotating shaft 10 and extending in the vertical direction. It can be engaged with the formed engagement groove 17c. The spring 27 is connected to the rotating shaft 10 and the manual operation shaft 26, and the manual operation shaft 26 is arranged between the spring 2 and the manual operation shaft 26. The direction in which the engaging groove 17c and the key 25 are always engaged under the urging force of 7. is constantly energized.

[0015] Further, the tip of the rotating shaft 10 protrudes outward from the case 9, and a roof panel is attached to this tip. A detection mechanism 28 is provided to detect the position of the rotary shaft 10 from the rotation angle of the rotary shaft 10. There is. This detection mechanism 28 is covered by a cover 29 fixed to the case 9. It is housed between the base 9 and the cover 29.

[0016] Next, the operation of the present invention will be explained.

[0017] When the opening 2 is in the closed state, the motor is operated to rotate its rotating shaft 19. Then, the first gear 18 rotates via the worm gear 20. This first gear 18 times As a result of rotation, the engagement hole 21 and the protrusion 23 engage with each other via the rubber material 24, and the first gear 18 The rotation is transmitted to the sleeve 17 and the sleeve 17 rotates. This sleeve 17 Due to the rotation, the rotation is transmitted to the rotating shaft 10 via the key 25, and the rotating shaft 10 is rotated. After that, this rotation causes the second gear 11, intermediate gear 12, output gear 13 and output gear to rotate. The force is transmitted to the force shaft 14, and finally the pinion gear 15 rotates. This piniongi The rotation of the wheel 15 pushes and pulls the cable 8, which causes the cable 8 to be pushed and pulled through the link mechanism 4. Then, the roof panel 5 slides. As a result, the opening 2 changes from the closed state to the open state. Become. Also, contrary to the above, the motor is operated to rotate its rotating shaft 19. As a result, the roof panel 5 slides in the opposite direction to the above, changing the opening 2 from the open state to the closed state. state. Please note that the roof panel 5 may no longer slide due to motor failure, etc. In this case, the manual operation shaft 26 is moved upward against the biasing force of the spring 27 to open the key 2. 5 is disengaged from the engagement groove 17c, and in this state, the manual operation shaft 26 is rotated. By rotating, the rotating shaft 10 rotates without rotating the sleeve 17. This allows the roof panel 5 to be slid.

[0018] As described above, the rotation of the first gear 18 is caused by the rubber material 24 between the engagement hole 21 and the protrusion 23. It is transmitted to the sleeve 17 by engagement via the . Therefore, due to motor operation, The impact force is absorbed by the rubber material 24, and only the driving force is transferred from the first gear 18 to the sleeve. 17. This allows the cable to be damaged by the impact force caused by motor operation. The operation of the gear 8 may be adversely affected, or the operation of the second gear 11, intermediate gear 12 and output gear may be The durability of No. 13 does not deteriorate. Further, the rubber material 24 is connected to the first gear 11. It is arranged in the matching hole 21 and the sleeve 17 is located in the notch 22 of the first gear 11. ing. In other words, the rubber material 24 and the sleeve 17 are disposed within the thickness of the first gear 11. It is. This allows the motor to save space without increasing its size in the axial direction. It can absorb the impact force caused by the operation of the motor.

[0019]

[Effect of the idea]

The present invention is arranged at the front edge of the vehicle of an opening formed in the roof of the vehicle. In the vehicle sunroof drive system that opens and closes the roof panel. a drive means, a first gear linked to the drive means, and a first gear linked to the first gear. a second gear, disposed within the thickness of the first gear between the first gear and the second gear; a shock absorbing mechanism linked to the second gear and linked to the roof panel. It has a gear mechanism linked to a cable and constitutes a drive device for a sunloose for a vehicle. Therefore, it has the following effects.

[0020] The impact force caused by the operation of the driving means is absorbed and only the driving force is transferred from the first gear to the second gear. The impact force due to actuation of the drive means can be transmitted to the gear mechanism and cable. This may adversely affect the operation of the cable or reduce the durability of the second gear and gear mechanism. can be prevented from worsening.

[0021] A buffer mechanism for absorbing shock caused by the operation of the driving means is arranged within the thickness of the first gear. This reduces the impact caused by the operation of the drive means without increasing the size in the axial direction and saving space. can be absorbed.
