Abstract

The present invention relates to a hands-free electric scooter including: a bottom housing; a steering housing disposed on the bottom housing; a steering shaft having a pressurizing plate mounted along the lower periphery thereof, a horizontal protrusion formed on one side of the pressurizing plate, a manipulating rod mounted on the underside of the horizontal protrusion, and a stopper mounted along the intermediate periphery thereof; a steering jig having an insertion hole formed at one side thereof, a micro switch mounted at the rear side of the insertion hole and having a grounding stick disposed at one side thereof, and an installation hole formed at the front side of the insertion hole; and a potential meter adapted to control direction changes of the hands-free electric scooter.

Claims

1. A hands-free electric scooter having a bottom housing 10 into which a controller 13 on which a variety of sensors inclusive of a gyroscope sensor are arranged, batteries 12, and motors 11 are housed, and a pair of wheels 14 mounted on both sides of the bottom housing 10, thereby sensing an inclined angle of a rider'"'"'s body and performing riding according to the sensed result, the hands-free electric scooter comprising:

a steering housing 30 disposed on the bottom housing 10;

a steering shaft 41 insertedly disposed at the interior of the steering housing 30 in such a manner as to have a seat 40 mounted along the top portion thereof and to be assembled to a steering jig 50 along the lower portion thereof, the steering shaft 41 having a pressurizing plate 43 mounted along the lower periphery thereof, a horizontal protrusion 44 formed on one side of the pressurizing plate 43, a manipulating rod 45 mounted on the underside of the horizontal protrusion 44, and a stopper 42 mounted along the intermediate periphery thereof so as to prevent the steering shaft 41 from being escaped from the steering housing 30;

the steering jig 50 having an insertion hole 51 formed at one side thereof so as to insert the steering shaft 41 thereinto, a micro switch 63 mounted at the rear side of the insertion hole 51 so as to control the drive of the motors 11 and having a grounding stick 64 disposed at one side thereof, and an installation hole 53 formed at the front side of the insertion hole 51 so as to mount a potential meter 60 therealong; and

the potential meter 60 adapted to control direction changes of the hands-free electric scooter and having a manipulating plate 61 mounted along the top periphery thereof, the manipulating plate 61 having an elongated hole 62 formed at one side thereof,

wherein if the steering shaft 41 is insertedly fitted to the insertion hole 51 of the steering jig 50, the pressurizing plate 43 serves to pressurize the grounding stick 64 of the micro switch 63, thereby allowing the manipulating rod 45 to be inserted into the elongated hole 62 of the manipulating plate 61.

2. The hands-free electric scooter according to claim 1, wherein between the horizontal protrusion 44 formed on one side of the pressurizing plate 43 and an upward protrusion 52 formed at the front side of the installation hole 53 of the steering jig 50 is interposed a first spring 46, and between the horizontal protrusion 44 formed on one side of the pressurizing plate 43 and a mounting hole 32 formed on the top portion of the steering housing 30 is interposed a second spring 47.
