DETAILED DESCRIPTION

(6) Hereinafter, example embodiments are described in more detail with reference to the accompanying drawings. It should be understood that these embodiments may be modified in various ways and the scope of the present disclosure should not be construed as being limited to the following embodiments. The embodiments are provided to more completely explain the present disclosure to those skilled in the art.

(7) Further, in the specification, the terms unit etc, mean one unit for processing at least one function or operation and may be achieved by combination of hardware.

(8) The present disclosure relates to a dual sunroof having a tilting function and provides a structure for supporting an end of a front glass panel 11 and an end of a rear glass panel 12 lifting from the roof panel 100 of a vehicle when the front glass panel 11 and the rear glass panel 12 of a dual sunroof are simultaneously tilted.

(9) Front glass panel 11 and rear glass panel 12 of a dual sunroof in an example embodiment are configured to sequentially or simultaneously tilt up. By coupling a support 25, 26 and a sled 30 to each other in the example embodiment, vibration generated as the sunroof tilts is reduced and the durability of the sunroof is therefore improved. FIG. 2 is a view showing the configuration of a dual tilt sunroof structure in an example embodiment.

(10) As shown in the figure, a dual tilt sunroof structure relates to a dual sunroof having a front glass panel 11 and a rear glass panel 12. Front glass panel 11 and rear glass panel 12 are disposed on the roof panel of a vehicle and the structure includes front carriages 21 disposed at both ends of the front glass panel 11 to integrally move with front glass panel 11 and rear carriages 22 disposed at both ends of rear glass panel 12 to integrally move with rear glass panel 12.

(11) The structure also includes front sleds 31 and rear sleds 32 that move in the front to rear direction of a vehicle on guide rails 40 disposed at both ends of the roof panel. Sleds 30 move on guide rails 40 such that front glass panel 11 and rear glass panel 12 are tilted up.

(12) Sleds 30 are connected with a motor in a vehicle through a cable 60 and a controller moves front sleds 31 and rear sleds 32 on guide rails 40 in the front to rear direction of a vehicle by operating motor 50 in response to a request from a user.

(13) Motor 50 is connected with sleds 30 through cable 60, and front sled 31 and rear sled 32 are moved in the same direction by the power from motor 50.

(14) When front sleds 31 and rear sleds 32 are moved on guide rails 40, front sleds 31 are moved to a position where they come in contact with support 25 at first ends of the rear sides of front carriages 21 and rear sleds 32 are moved to a position where they come in contact with support 26 at first ends of the rear sides of rear carriages 22.

(15) The supports 25, 26 may be coupled to sleds 30, respectively, and front and rear projections 23 and 24 protruding at the supports 25, 26 can be fastened into front and rear guide grooves 33 and 34 formed at sleds 30, respectively. Alternatively, the structure may have one or more projections 23 and 24 formed at front sleds 31 and rear sleds 32 and may include front carriages 21 or rear carriages 22 having front or rear guide grooves 33 or 34 corresponding to projections 23 and 24.

(16) Front sleds 31 and rear sleds 32 in an example embodiment come in contact with the supports 25, 26 at the first ends of front carriages 21 and the supports 25, 26 at the first ends of rear carriage 22 when the dual sunroof is tilted. Second ends of carriages 20 (i.e. the ends where the supports 25, 26 are not formed) have a predetermined curvature to be able to rotate along guide rails 40, so the sunroof can be easily tilted.

(17) The second ends of one or more carriages 20 and guide rails 40 are coupled by circular guides 41 so that when front glass panel 11 and rear glass panel 12 are tilted, the second ends of e carriages 20 can be rotated along circular guides 41.

(18) FIG. 3 is a view showing the dual tilt sunroof structure with the front and rear glass panels 11 and 12 closed in an example embodiment.

(19) As shown in FIG. 3, when glass panels 11 and 12 are closed, sleds 30 are positioned on the guide rail 40 not in contact with the supports 25, 26 on the rear sides of carriages 20. Accordingly, carriages 20 that are integrally moved with front and rear glass panels 11 and 12 are not tilted yet.

(20) On the other hand, FIG. 4 is a view showing the dual tilt sunroof structure with the dual sunroof tilted in an example embodiment.

(21) When the dual sunroof is tilted by a request from a user, power is applied to front sled 31 and rear sled 32 from motor 50 to tilt sled glass panel 11 and rear glass panel 12, and front tread 31 and rear sled 32 are moved toward the rear of the vehicle on the guide rail 40.

(22) Front sled 31 and rear sled 32 that are moved in this way come in contact with the support 25 on the rear side of front carriage 21 and the support 26 on rear side of the rear carriage 22.

(23) According to another embodiment, front sleds 31 may be coupled to the support 25 and rear sleds 32 may be coupled to the support 26. In this configuration, projections 23 and 24 protruding to a side on the rear sides of carriages 20 may be fitted into front and rear guide grooves 33 and 34 at first ends of sleds 30.

(24) When the dual sunroof is tilted, as described in this embodiment, the front and rear supporting porting portions are brought in contact with front sleds 31 and rear sleds 32, thereby providing a structure that fixes and supports first ends of glass panels 11 and 12 lifted for tilting.

(25) The second ends of carriages 20 lifted for tilting can be rotated about guide rails 40, so they may follow a predetermined curvature for easy rotation.

(26) Furthermore, when the dual sunroof is tilted, front sleds 31 and rear sleds 32 simultaneously come in contact with the supports 25, 26 of front carriages 21 and the supports 25, 26 of rear carriages 22. The first ends of front glass panel 11 and rear glass panel 12 that come in contact with sleds 30 are lifted and the second ends of front glass panel 11 and rear glass panel 12 are rotated about predetermined portions of guide rails 40. Further, when the dual sunroof is tilted, front sleds 31 and rear sleds 32 simultaneously or sequentially come in contact with the corresponding supports 25, 26.

(27) The example embodiments described above may be used in other various combinations, changes, and situations. That is, the embodiments may be changed or modified within the range of the concept of the present invention, the range equivalent to the above description, and/or the range of the technologies and knowledge in the art. The embodiments provide the best state for accomplishing the spirit of the present invention and may be changed in various ways for the detailed application and the use of the present invention. Accordingly, the above description does not limit the present invention to the embodiments. Further, the claims should be construed as including other embodiments.
