Electric vehicle
DCFirst Claim
1. An electric balance vehicle, comprising:
- a first platform;
a second platform;
a bottom cover comprising a first bottom cover removably connected to the first platform and a second bottom cover removably connected to the second platform, wherein the first platform and the second platform are made of a first material, and wherein the first bottom cover and the second bottom cover are made of a second material that differs in strength from the first material;
a rotation mechanism disposed between the first platform and the second platform, wherein the rotation mechanism allows the first platform and the first bottom cover to rotate relative to the second platform and the second bottom cover;
a first wheel rotatably fixed at a first end of the first platform and a second wheel rotatably fixed at a second end of the second platform, wherein the first end and the second end are at opposites ends of the electric balance vehicle;
a first motor mounted within the first wheel and configured to drive the first wheel;
a second motor mounted within the second wheel and configured to drive the second wheel;
a plurality of sensors;
a power supply disposed between the bottom cover and one of the first platform or the second platform;
at least one controller electrically coupled to the first motor, the second motor, the plurality of sensors, and the power supply and configured to control the first motor and the second motor, respectively, to drive the first wheel and the second wheel, respectively, using power from the power supply and based on signals from the plurality of sensors; and
a limiting mechanism configured to limit an overlarge relative rotation angle between the first platform and the second platform, wherein the limiting mechanism is disposed between the first platform and the second platform.

Abstract
An electric self-balancing vehicle including a top cover, a bottom cover, an inner cover, a rotating mechanism, two wheels, two hub motors, a plurality of sensors, a power supply, and a controller is described herein. The top cover includes a first top cover and a second top cover disposed symmetrically and rotatable relative to each other. The bottom cover is fixed to the top cover and includes a first bottom cover and a second bottom cover disposed symmetrically and rotatable relative to each other. The inner cover is fixed between the top cover and the bottom cover and includes a first inner cover and a second inner cover disposed symmetrically and rotatable relative to each other. The rotating mechanism is fixed between the first inner cover and the second inner cover. The two wheels are rotatably fixed at two sides of the inner cover, respectively. The two hub motors are fixed in the two wheels, respectively. The plurality of sensors is disposed between the bottom cover and the inner cover, respectively. The power supply is fixed between the first bottom cover and the first inner cover. The controller is fixed between the second bottom cover and the second inner cover, the controller is electrically connected with the plurality of sensors, the power supply, and the hub motors, and the controller controls the hub motors to drive the corresponding wheels to rotate according to sensing signals transmitted by the sensors.
