Abstract

An electric powered scooter having a tubular frame extending between a front steerable wheel and a rear electrically powered wheel. The tubular frame extends below the wheel centers parallel to the surface of the ground between the front and rear wheels. A platform for the standing support of the scooter rider is mounted from frame mounted brackets so as to define between the upper portion of the tubular frame and the lower portion of the platform a spatial interval. Four batteries--with two on each side of the central frame member--are mounted to the underside of the platform which each battery supported by a case enclosing the battery at the bottom and mounting the battery flush to the underside of the platform at the top. An enclosed wiring channel is formed with the tubular frame at the bottom, the batteries on either side, and the bottom of the platform at the top. The scooter design thus has the powering electric batteries mounted in a concealed under body position relative to the platform giving an electric scooter having a low center of gravity with optimal riding profile.

Claims

1. An electrically powered scooter for powered movement over a ground surface comprising in combination:

a scooter chassis having a rear wheel mount at one end and a front wheel mount at the other end with a chassis support member extending therebetween;

a chassis supported front wheel mounted to the front wheel mount for turning steering movement with respect to the front wheel mount;

the chassis includes a single central tubular member extending between the front wheel mount and the rear wheel mount;

a chassis supported rear wheel;

a chassis supported motor;

means adjacent the rear wheel mount for enabling the chassis supported motor to drive the chassis supported rear wheel;

a platform supported from the scooter chassis between the rear wheel mount and the front wheel mount defining an upper surface for supporting a scooter rider and an underside exposed to the ground surface over which the scooter passes;

a battery support between the underside of the platform and ground over which the scooter passes for supporting motor driving batteries;

a plurality of batteries mounted to either side of the single central tubular member in depending relations from the platform; and

,

the batteries mounted to either side of the single central tubular member define a wiring channel therebetween with the platform overhead for enabling scooter operating wiring to pass between scooter controls at the forward portion of the chassis and the chassis supported motor.

2. An electrically powered scooter for powered movement over a ground surface comprising in combination:

a scooter chassis having a rear wheel mount axis at one end and a front wheel mount axis at another end with a chassis support member extending therebetween;

a chassis supported front wheel mounted to the front wheel mount axis for turning steering movement with respect to the chassis;

a chassis supported rear wheel mounted to and turning on the rear wheel mount axis;

a single tubular member forming a sole structural chassis connecting member between the front wheel mount axis and the rear wheel mount axis, the single tubular member extending below the front wheel mount axis and the rear wheel mount axis;

a chassis supported motor;

means adjacent the rear wheel mount axis for enabling a chassis supported motor to drive the scooter chassis supported rear wheel;

a platform supported on the single tubular member of the scooter chassis between the rear wheel mount axis and the front wheel mount axis defining an upper surface for supporting a scooter rider and an underside exposed to the ground surface over which the electrically powered scooter passes; and

,

a battery support between the underside of the platform and ground over which the electric powered scooter passes for supporting motor driving batteries; and

,

batteries supported on either side of the single tubular member.

3. An electrically powered scooter according to claim 2 and wherein:

the single tubular member is lower than the batteries supported on either side of the single tubular member.
