3 to 6, the surfboard driven by power according to an embodiment of the present invention has a hull 20 and the hull 20 at regular intervals along the longitudinal direction of the hull 20. A handle 32 having both ends coupled and fixed to each other via a pair of pillars 24 and 26 installed on the deck 22 and elbows 28 and 30 coupled to the pair of pillars 24 and 26. And a main switch 36 installed in the machine room 23 disposed on the deck 22 to control the output of the battery 34 charged with DC power and the DC power charged in the battery 34. And an inverter 38 for receiving a DC power charged in the battery 34 and boosting the DC power to AC power when the main switch 36 is switched on, and a fixed terminal provided at an output terminal of the inverter 38. 40 and a boosted bridge output from the inverter 38 when the fixed terminal 40 contacts the first movable terminal 42. The transmission 44 receives power to increase the rotational speed per minute (rpm) and the hull 20 is rotated at a high speed while receiving the increased rotational speed per minute to advance the hull 20 at high speed, and the hull When the fixed terminal 40 contacts the second movable terminal 43 to advance the speed 20 at a low speed, the water is driven in accordance with the rotation of the drive motor 46 and the drive motor 46 which rotate at low speed. Heat is generated when the impeller 48 located in the water and the driving motor 46 are disposed in the rotating shaft 46a of the driving motor 46 to advance the hull 20 while pushing the engine. Fan motor 50 driven when the main switch 36 is switched on to cool the air, and disposed on the rotation shaft 50a of the fan motor 50 to cool the driving motor 46. Song which inhales air through bellows hose 51 and blows it to the said drive motor 46 It is coupled to a through-hole (not shown) formed in the cover 54 to blow out the air fan 52 and the air blown out by the blower fan 52 to cool the driving motor 46 to the outside. It is composed of a discharge hose 57.

The bellows hose 51 and the discharge hose 57 are bent so that water does not penetrate into the machine room 23, and a lock member 54a is installed at one side of the cover 54.

In the figure, reference numeral 55 denotes a socket for coupling the battery 34 and the inverter 38, and the cover 54 is provided to be opened and closed via a hinge 56.

55a and 55b indicate a + electrode clamper and a-electrode clamper respectively installed in the socket 55, and the + electrode clamper 55a is coupled to the + electrode 34a of the battery 34. The -electrode clamper 55b is coupled to the -electrode 34b of the battery 34.

38a is a plug for coupling the inverter 38 to an unillustrated jack of the socket 55, and 44a is a plug for coupling to an unillustrated jack formed in the socket 55. As shown in FIG.

Next, the operation and effects of the surfboard driven by the power according to the embodiment of the present invention configured as described above will be described.

First, the + electrode clamper 55a and the -electrode clamper 55b provided in the socket 55 are electrically connected to the + electrode 34a and the -electrode 34b of the battery 34, respectively. The plug 38a of the inverter 38 is electrically coupled to an unillustrated jack of the socket 55, and the plug 44a of the transmission 44 is connected to an unillustrated jack of the socket 55. After being electrically connected, the person who wants to enjoy the surfboard grabs the handle 32 while boarding the hull 20, and uses the foot to switch on the main switch.

At this time, as the fan motor 50 is driven and the blowing fan 52 installed on the rotation shaft 50a of the fan motor 50 is rotated, external air is sucked through the bellows hose 51 to drive the drive motor. Blows air to the 46 to cool the heat generated during the driving of the drive motor 46, and the air heated by the blower fan 52 to cool the drive motor 46 is cooled by the cover ( It is discharged to the outside through the discharge hose 57 coupled to the through hole (not shown) formed in the 54.

In this state, when the first movable terminal 42 is stepped on, the first movable terminal 42 receives 12 Vdc from the inverter 38 as the electrical contact with the fixed terminal 40 causes an AC power supply, for example, 220 Vac. The impeller 48 installed on the rotation shaft 46a of the drive motor 46 is rotated by receiving the AC power converted and outputted from the transmission 44 to increase the rotation speed to rotate the drive motor 46 at high speed. While rotating at high speed, the surfboard of the present invention is advanced toward the driving direction at high speed by pushing water backwards.

At this time, the moving direction of the hull 20 moves forward while the hull 20 is turning in the direction of applying its weight to the handle 32 that is held by a person who enjoys surfing.

On the other hand, if the user wants to run at a low speed while driving the surfboard at high speed, the second movable terminal 43 is in contact with the fixed terminal 40 by stepping on the second movable terminal 43 with his feet. Accordingly, the AC power output from the inverter 38, for example, 220Vac is directly applied to the drive motor 44, so that the surfboard of the present invention, that is, the hull 20 travels at a low speed.

When the surfboard of the present invention, that is, the hull 20 is to be stopped, the main switch 36 is stepped on again to stop.

In the above description, although illustrated and described with reference to specific embodiments, the present invention is not limited to this, for example, by those of ordinary skill in the art without departing from the concept of the present invention Of course, the design can be changed in various ways.

As described above, according to the surfboard driven by the power of the present invention, not only an inexperienced person can easily enjoy surfing, but also have a very excellent effect of enjoying surfing even without wind.
