A vehicle frame that includes first and second frame portions. The first frame portion has a plurality of struts associated with each other to form a first framework. The second frame portion is associable with the first frame portion in a stiffening association for significantly increasing the stiffness of the first frame portion. The associated first and second frame portions are configured to support a rider sitting on the vehicle frame. The associated frame portions also define an interior cavity dimension for housing a component of the propulsion system for propelling the vehicle. The associated frame portions also comprise attachments for supportedly connecting two wheels of the vehicle, a seat disposed on the frame, and other vehicle accessories and systems.

Composite construction vehicle frame

A two-wheeled electric scooter principally powered by batteries which together provide more than 100 volts. The scooter carries an onboard recharging system to replenish the battery supply. Accordingly, the onboard recharging system is not called upon to provide the main power source for acceleration and other operating conditions. A recharging system is implemented either as a fuel cell which trickle charges the battery, or an internal combustion engine which recharges the battery through a mechanical charging unit such as an alternator or generator. Regenerative braking is provided so as to further conserve energy by back driving the motor to recharge the battery pack during braking. Connections are provided for an external power source such as an AC outlet to be plugged into the scooter so as to provide an alternate mechanism to recharge the batteries.

Electric scooter with on-board charging system

The present invention discloses an electric vehicle frame having a lower portion and an upper portion. The lower portion includes a base and integral sidewalls. The sidewalls extend from the base to form an open cavity. The upper portion detachably joins to the lower portion such that the upper portion covers the cavity and forms a frame assembly which defines an enclosed chamber therein. The strength of the assembly is substantially greater than the strength of each of the portions prior to being joined. The lower and upper portions are formed of cast aluminum. The present invention further includes a method of assembling an electric vehicle, which includes using the frame and a plurality of subassemblies, and the electric vehicle formed therefrom, particularly in the form of a motor scooter.
