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.

First claim

What is claimed is:

1. An electric balance vehicle, comprising:
a top cover comprising a first top cover and a second top cover disposed symmetrically and rotatable relative to each other;
a bottom cover fixed to the top cover, the bottom cover comprising a first bottom cover and a second bottom cover disposed symmetrically and rotatable relative to each other;
an inner cover fixed between the top cover and the bottom cover, the inner cover comprising a first inner cover and a second inner cover disposed symmetrically and rotatable relative to each other;
a rotating mechanism fixed between the first inner cover and the second inner cover, the rotating mechanism having two bearings, a shaft sleeve, and two snap springs, the two bearings fixed to the first inner cover and the second inner cover, respectively, and the shaft sleeve fixed inside the two bearings and fixed to the inner cover via the two snap springs;
two wheels rotatably fixed at two sides of the inner cover, respectively;
two hub motors fixed in the two wheels, respectively;
a plurality of sensors disposed between the bottom cover and the inner cover;
a power supply fixed between the first bottom cover and the first inner cover;
a controller fixed between the second bottom cover and the second inner cover, wherein 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; and
two pedals, wherein the pedals are fixed to the top cover and the inner cover.

2. The electric balance vehicle according to claim 1 , wherein the pedals have mutually separated friction strips disposed on upper surfaces of the pedals.

3. The electric balance vehicle according to claim 1 , wherein the first top cover and the second top cover have hollow spaces, respectively, the first inner cover and the second inner cover have recesses at positions corresponding to the hollow spaces, respectively, and the hollow spaces are combined with the recesses to form pedal cavities for containing the pedals.

4. The electric balance vehicle according to claim 1 , wherein the inner cover has a cylindrical barrel, and the bearings and the shaft sleeve are installed in the barrel via the snap springs.

5. The electric balance vehicle according to claim 1 , further comprising a decorative lamp disposed at the bottom cover.

6. The electric balance vehicle according to claim 1 , wherein the top cover further includes two indicating screens electrically connected with the controller, one indicating screen displays a remaining capacity of the power supply, and the other indicating screen displays a working state of the electric balance vehicle.

7. The electric balance vehicle according to claim 1 , wherein the sensor comprises a gyroscope, an acceleration sensor, and an inductive switch, the inductive switch senses whether a user stands on the electric balance vehicle so as to be on or off, the controller receives the sensing signal of the inductive switch to control the hub motors to work or to stop, and the controller receives the sensing signals of the acceleration sensor and the gyroscope to control the hub motors to change a state or to keep the state.

8. The electric balance vehicle according to claim 7 , wherein the inductive switch is an infrared photoelectric sensor.

9. The electric balance vehicle according to claim 1 , further comprising a charging interface disposed at the bottom cover.

10. The electric balance vehicle according to claim 9 , further comprising an interface cover, wherein the interface cover covers the charging interface.

11. The electric balance vehicle according to claim 1 , further comprising a limiting shaft disposed between the first inner cover and the second inner cover, wherein the length of the limiting shaft in the second inner cover is larger than the length of the limiting shaft in the first inner cover.

12. The electric balance vehicle according to claim 1 , wherein the top cover has two arc-shaped projections, and the two arc-shaped projections are located above the two wheels and cover a part of the wheels, respectively.

13. The electric balance vehicle according to claim 12 , wherein the width of the arc-shaped projections is larger than the width of the wheels.

14. The electric balance vehicle according to claim 1 , wherein the top cover and the bottom cover are made of plastic, and the inner cover is made of aluminum alloy.

15. The electric balance vehicle according to claim 1 , further comprising a remote controller, wherein the controller receives a control signal sent by the remote controller.

16. The electric balance vehicle according to claim 1 , wherein the controller has a storage unit and a correction unit, the storage unit stores an initial balance state of the electric balance vehicle, and the correction unit corrects a current balance state of the electric balance vehicle.
