The present invention relates generally to vehicles and more particularly, to a sunroof structure of a vehicle.
The sunroof of a conventional vehicle can only be opened in an inclined manner, or can only move forward or backward after it is opened. In order to prevent the sunroof from protruding beyond the vehicle body after it is opened, the area of the hollow portion (window) of the roof of the vehicle will be limited in a certain extent. Theoretically, the maximum window area cannot exceed half of the roof area. Because the sunroof driving mechanism and linkage mechanism also need space for installation, the area of the conventional sunroof having a dimension reaching two-thirds of the roof area will be the maximum extent.
In another aspect, in addition to the need to open the sunroof to enjoy the scenery, the camper also has the need for sunshade and rain protection on the side thereof. Therefore, how to use the most simplified design to fulfill various needs has become an issue to be improved by the industry.
The present invention has been accomplished in view of the above-noted circumstances. It is an objective of the present invention to provide a sunroof structure of a vehicle, which can greatly increase the area of the window opening.
It is another objective of the present invention to provide a sunroof structure of a vehicle, which can provide a side shielding function when it is opened.
It is still another objective of the present invention to provide a sunroof structure of a vehicle, which has a simple structural design and low manufacturing cost, saves space required for installation, and has great market potential.
To attain the above objectives, the present invention provides a sunroof structure adapted for being installed to a vehicle comprising a vehicle body and a pivot mount. The vehicle body comprises a roof plate having a hollow portion. The sunroof structure comprises at least one first mount, a window panel, a transmission member, and a link. The first mount is adapted for being mounted to an inside of the vehicle body. The window panel is adapted for being disposed to the hollow portion and comprises a main body, at least one second mount disposed on a bottom side of the main body, and a third mount disposed on the bottom side of the main body. The transmission member comprises a first rotational shaft rotatably disposed with the first mount, a second rotational shaft rotatably disposed with the second mount, and at least one crank connected between the first and second rotational shafts. The link includes a first end pivotally connected with the third mount, and a second end adapted for being pivotally connected with the pivot mount of the vehicle body. As a result, the window panel is drivenable to close or open the hollow portion. With the aforesaid structural features, the area of the window opening can be greatly increased, and a side shielding function can be provided when the window panel is driven to open the hollow portion. Further, the sunroof structure has a simple structural design to result in low manufacturing cost, and saves the space required for installation, thereby providing great market potential.
The present invention will become more fully understood from the detailed description given herein below and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
The structure and technical features of the present invention will be detailedly described hereunder by an embodiment and accompany drawings. As shown in
The two first mounts 20 are used to be disposed on an inside of the vehicle body 3, and located at places close to the hollow portion 4 but not limited to the parts of the roof plate 5 or the vehicle body 3. The two first mounts 20 are also spacedly arranged at an interval along the front and rear direction of the vehicle body 3.
The transmission member 22 includes a first rotational shaft 24 rotatably disposed with the two first mounts 20, a second rotational shaft 26 rotatably disposed with the second mounts 16, and two cranks 28 connected between the first and second rotational shafts 24 and 26. The number of the crank 28 is not limited to the one shown in this embodiment. One or more cranks 28 can be used. One or more reinforcing rods may be further provided between the two cranks 28 to enhance the structural strength.
The link 30 has a first end 31 pivotally connected with the third mount 17, and a second end 32 adapted for being pivotally connected with the pivot mount 6 of the vehicle body 3. In this embodiment, the link 30 is a straight rod having a length L1 greater than a half of the width W1 of the window panel 12. In another embodiment of the present invention, the length L1 of the link 30 is exactly equal to a half of the width W1 of the window panel 12.
The drive device 34 is used to be disposed on the inside of the vehicle body 3 and can drive the first rotational shaft 24 to rotate. The drive device 34 may be an electric or pneumatic motor, electric cylinder, pneumatic cylinder, or hydraulic cylinder. In this embodiment, the drive device 34 includes a motor 36 for being disposed on a side wall 7 of the vehicle body 3, a driving gear 38 coaxially connected with a drive shaft 37 of the motor 36, and a driven gear 40 coaxially connected with the first rotational shaft 24 of the transmission member 22 and engaged with the driving gear 38. As such, as shown in
In another aspect, because a special design that a distance D1 between a pivotal axis of the second mounts 16 and a pivotal axis of the third mount 17 (equivalent to the distance between the second rotational shaft 26 and the first end 31 of the link 30 in the viewing angle of
With the above-disclosed structural features, the sunroof structure 10 of the present invention can greatly increase the area of the window opening, which not only helps air convection and lowers the temperature inside the vehicle, but also saves the cost of installing range hoods for cooking. Further, the sunroof structure 10 can provide a side shielding function to the vehicle when it is opened. Moreover, the sunroof structure 10 has a simple structural design to result in low manufacturing cost, and saves the space required for installation, thereby providing great market potential and thus achieving the objectives of the present invention.
Based on the above-mentioned structural design, various modifications to the sunroof structure 10 provided by the present invention may be made. For example, one second mount 16 and one first mount 20 may be sufficient for accomplishing the present invention. That is, one or more first mounts 20 or second mounts 16 may be used in the present invention. For the drive device 34, any conventional driving apparatus or actuator may be used as long as it can drive the transmission member 22 to rotate. Alternatively, the drive device 34 may be omitted, such that the sunroof structure 10 may be driven manually. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
