Abstract:
A motorized cart, including: a collapsible frame with a collapsible storage compartment, a front wheel, and two rear wheels rotating about a single axis. The frame has a folding support platform including hingedly connected first and second portions. The first portion rotatably connects at a front of the frame, and the second portion rotatably connects to a rear of the frame. A drive compartment houses a battery, a drive controller, and a motor for driving a rear wheel, and is positioned on the frame to position the battery, the drive controller, and the motor below and forward of the axis in an expanded, upright mode, thereby positioning a cart center of gravity forward of the axis. The drive compartment is shaped and positioned on the frame to: permit the collapsing of the storage compartment and the frame to a collapsed mode; provide clearance for the front wheel during transition between the collapsed mode and the expanded, upright mode; and substantially vertically align the cart center of gravity with the axis in a tilted mode, operating only on the two rear wheels.
