In accordance with the present invention, there is provided a motorized beach vehicle with a safety remote control and emergency safety switch power shutoff device, comprising an ACG (alternating current magneto generator) assembly, and a CDI (capacitor discharge ignition) unit for controlling an engine to operate normally or stop operating, an electrical power of the CDI unit being supplied by a battery, wherein:




the CDI unit has an engine operation stopping line that is connected to a relay, a remote control unit, and a safety switch;




the remote control unit receives an on/off signal transmitted from a remote controller, to energize the relay, so as to shutoff or conduct the engine operation stopping line of the CDI unit; and




the safety switch includes two lines connected to the relay, each of the two lines is disposed at a normally open state, an electrically conductive seat is mounted on the two lines, an elastic sleeve is mounted on the electrically conductive seat, the safety switch is mounted on the elastic sleeve, a rubber cap is mounted on the safety switch, the rubber cap is connected to a first end of a strap which has a second end that is tied on a driver's body, so that the rubber cap is detached from the safety switch by the strap in an emergency condition.




Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

73


, so that the electrically conductive seat


74


may connect the two lines


71


and


72


to form a circuit.




The rubber cap


75


has an inner wall formed with a snap groove


78


, and the safety switch


70


has an outer wall provided with a snap hook


77


that may be snapped into the snap groove


78

.




The rubber cap


75


is connected to a first end of a strap (or rope)


79


which has a second end that may be tied on the driver's body, so that when the driver falls from the motorized beach vehicle


10


, the rubber cap


75


may be detached from the safety switch


70


by the strap


79


.




Referring to

FIGS. 10 and 11

,

FIG. 10

is a side plan cross-sectional assembly view of the safety remote control and emergency safety switch power shutoff device of a motorized beach vehicle in accordance with the preferred embodiment of the present invention, and

FIG. 11

is a side plan cross-sectional exploded view of the safety remote control and emergency safety switch power shutoff device of a motorized beach vehicle in accordance with the preferred embodiment of the present invention.




When the driver falls from the motorized beach vehicle


10


or when the driver cannot control and operate the motorized beach vehicle


10


normally, the strap (or rope)


79


tied on the driver's body may pull the rubber cap


75


which may be moved from the position as shown in

FIG. 10

to the position as shown in

FIG. 11

, so that the rubber cap


75


may be automatically detached from the safety switch


70


by pulling of the strap


79


, thereby shorting the lines


71


and


72


of the safety switch


70


, and thereby disconnecting the engine operation stopping line


31


of the CDI unit


30


of the driving motorized beach vehicle


10


, so as to stop operation of the motorized beach vehicle


10


, thereby achieving the purpose of safely shutting the electrical power, so as to protect the driver's safety.
