    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • As illustrated in FIG. 1, a first preferred embodiment of the present invention includes a board (1), a solar cell (2), an accumulation unit (3), a control unit (4), and a motor (5). The board (1) is provided with a wheel (151) driven by the motor (5) to roll on. Both the solar cell (2) and the accumulation unit (3) are mounted to the board (1). The solar cell (2) is disposed on an upper surface of the board (1), and the accumulation unit (3) is respectively connected with a conductor to the motor (5) and the solar cell (2) [i.e., conductively connected by convention means, not illustrated]. The solar cell (2) supplies power to the accumulation unit (3) in a detail construction as illustrated in FIGS. 2, and 3.
  • The board (1) includes two tube (11), two stands (12, 13), a front wheel stay (14), a rear wheel stay (15), a pivot (16), a support board (17), a face board (18), and a footrest (19). Both ends of each tube (11) are respectively fixed to the stands (12, 13). The support board (17) is fixed on the tubes (11) and the stands (12, 13). The face board (18) is disposed on the support board (17). A through hole (181) is disposed on the face board (18). The solar cell (2) is secured to the face board (18). The stand (12) is fixed to the front wheel stay (14) and the stand (13) is fixed to the rear wheel stay (15). The front wheel stay (14) is pivotally connected with front wheels (141), and the wheel (151) is disposed to the rear wheel stay (15). The rear wheel stay (15) includes the wheel (151), a start switch (43) to be described below, and the motor (5). The motor (5) uses a belt (51) to drive the wheel (151) to roll on. The pivot (16) is disposed to the rear wheel stay (15) and inserted into a spring (161) before being pivoted to the footrest (19). The footrest (19) includes a first end (191), a middle section, and a second end (192). The middle section of the footrest (19) is located between the first and the second ends (191, 192) and pivoted with a sleeve (193) to the pivot (16) of the board (1). The first end (191) corresponds in position to the start switch (43), and the second end (192), to the wheel (151). A hole (194) is bored close to the second end (192) of the footrest (19) to become a handle.
  • The accumulation unit (3) is provided with an over-charging protection (31), a power supply outlet (32) and a charging outlet (33). Both the power supply outlet (32) and the charging outlet (33) are provided on the rear wheel stay (15) to respectively supply power to an electric appliance or execute charging in case of the weak light intensity presents, e.g., during night hours, raining day, or winter season.
  • The control unit (4) includes a main switch (41), a safety switch (42), the start switch (43), and a fuse (44). The main switch (41) is disposed on the rear wheel stay (15) and connected to the accumulation unit (3). The safety switch (42) is located at the front wheel stay (14) and exposed out of the through hole (181). The start switch (43) is disposed to the rear wheel stay (15) of the board (1) and conductively connected to the motor (5) by means of a conductor. The conductive connection (i.e., connection by means of a conductor, a conventional means, thus not illustrated) among the main switch (41), the safety switch (42), and the start switch (43) merely takes place between the accumulation unit (3) and the motor (5). The start switch (43) corresponds in position to the first end (191) of the footrest (19).
  • In operation, the main switch (41) is first turned on, and the rider has one foot stepping on the safety switch (42) and the other foot stepping on the first end (191) of the footrest (1) to press the start switch (43), as illustrated in FIG. 4, to activate the motor (5) driving the wheel (151) to roll on.
  • While applying the brake as illustrated in FIG. 5, the rider simply steps on the second end (192) of the footrest (19) for the first end (191) of the footrest (19) to clear away from the start switch (43), thus to cut off the power supply while the rider presses the wheel (151) to apply the brake.
  • A second preferred embodiment of the present invention, as illustrated in FIG. 6, includes a board (1A), a solar cell (2A), an accumulation unit (3A) and a motor (5A). Wherein, the solar cell (2A) is disposed on a lower surface of the board (1A).
  • Thus, specific embodiments and applications of solar skateboard have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refer to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
