The disclosure relates to a watercraft, and more particularly to a wave-generating watercraft.
As shown in
Although the wave-generating units 11 are disposed outside the craft body 10 to save an interior space of the craft body 10 for accommodating accessories, the wave-generating units 11, which protrude outward from the craft body 10, can adversely affect the aesthetic quality of the craft body 10. Further, because the wave-generating units 11 extend down into the body of water, they are prone to collision with underwater rocks, barriers or the like.
Referring to
While the wave-generating watercraft 2 can solve aesthetic and collision problems due to the retractable wing plate 212, because the wing plate 212 has to directly counteract the reaction forces of water, the structural strength of the wing plate 212 in the form of plate is insufficient. Therefore, there is a need to improve the structural strength of a wave-forming unit of a wave-generating watercraft for long term use.
Therefore, an object of the disclosure is to provide a wave-generating watercraft that has good wave-generating effects, as well as high structural strength.
According to the disclosure, a wave-generating watercraft includes a craft body, and at least one wave-generating unit.
The craft body has front and rear ends, two opposite sides each extending between the front and rear ends, and at least one installation space formed in at least one of the opposite sides.
The at least one wave-generating unit is mounted within the at least one installation space, and includes a telescopic drive, a pivot seat, and a wave-forming block.
The telescopic drive is mounted to the craft body within the at least one installation space.
The pivot seat is mounted on the craft body within the at least one installation space.
The wave-forming block is pivotally connected to the pivot seat and the telescopic drive, and is driven by the telescopic drive to move between an extended position and a retracted position. The wave-forming block has an outside block face that extends rearward from the pivot seat and that faces outwards in a direction away from the at least one installation space, and an inside block face that extends from the pivot seat in a direction oblique to the outside block face and that is pivotally connected to the telescopic drive.
When the wave-forming block moves to the retracted position, the inside block face is pulled inward by the telescopic drive, and the outside block face moves to and spans the at least one installation space.
When the wave-forming block moves to the extended position, the inside block face rotates in a direction away from the telescopic drive, and the outside block face protrudes outwardly from the at least one installation space and is oblique to the front-rear direction.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiments with reference to the accompanying drawings, of which:
Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.
Referring to
To create waves during travel of the wave-generating watercraft, the telescopic drive 41 is actuated and stretched. As the telescopic drive 41 is connected to the inside block face 423, a torque is applied to the wave-forming block 42 to rotate it about the pivot seat 421. Therefore, the wave-forming block 42 is moved to the extended position, the inside block face 423 rotates in a direction away from the telescopic drive 41, and the outside block face 422 protrudes outwardly from the installation space 300 and is oblique to a front-rear direction of the craft body 3. The outside block face 422 thus can interact with water forces to generate waves. When the telescopic drive 41 retracts, the wave-forming block 42 moves to the retracted position, the inside block face 423 is pulled inward by the telescopic drive 41, and the outside block face 422 moves to the installation space 300 and spans the installation space 300. In this situation, the outside block face 422 lies in a plane substantially parallel to the front-rear direction of the craft body 3, and the wave-forming block 42 is received within the installation space 300.
The wave-forming block 42 is robust and able to reduce the risk of being damaged due to excessive water forces, as compared to the wave-forming plate in the prior art (
To sum up, the wave-forming block 42 is robust and has an optimized capability of bearing against water forces, thereby prolonging the service life.
In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiments. It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,” “an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects, and that one or more features or specific details from one embodiment may be practiced together with one or more features or specific details from another embodiment, where appropriate, in the practice of the disclosure.
While the disclosure has been described in connection with what are considered the exemplary embodiments, it is understood that this disclosure is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
