Power mechanism for automatically switching the operational mode of a child vehicle

1. A child vehicle configured to operate in a first operational mode and a second operational mode, comprising:

a power mechanism comprising a motor, an output gear operatively coupled to the motor, an engagement mechanism, and a drive wheel, wherein the engagement mechanism is disposed between the output gear and the drive wheel and selectively operably couples the output gear to the drive wheel;

at least one wheel coupled to the drive wheel for driving the child vehicle under the power of the motor; and

a manually-actuated propulsion switch operatively coupled to the power mechanism and having a first position and a second position, the propulsion switch configured to be in the first position as a result of engagement of an active force from a rider of the child vehicle on the propulsion switch, and the propulsion switch configured to automatically move from the first position to the second position upon disengagement of the active force from the rider on the propulsion switch,

wherein when the propulsion switch is in the first position the child vehicle is in the first operational mode and the wheel is being driven by the motor, and when the propulsion switch is in the second position the child vehicle is in the second operational mode and the wheel is allowed to rotate substantially free from drag or resistance due to the motor, and

wherein the engagement mechanism comprises a mount coupled to the output pear and one or more magnetic members, wherein the drive wheel includes a plurality of grooves, and wherein the one or more magnetic members engage the grooves in the drive wheel when in the first operational mode and are disengaged from the grooves in the drive wheel when in the second operational mode.

2. The child vehicle of claim 1 , wherein the engagement mechanism further comprises a fixing piece.

3. The child vehicle of claim 1 , wherein the mount is formed from metal and interacts with the one or more magnetic members.

4. The child vehicle of claim 2 , wherein the fixing piece is formed from metal.

5. The child vehicle of claim 1 , wherein the propulsion switch includes one of a button, lever, pedal or a rotating grip.

6. The child vehicle of claim 1 , wherein the propulsion switch includes a biasing member that automatically moves the propulsion switch from the first position to the second position.

7. The child vehicle of claim 1 , wherein the child vehicle is a scooter.

8. The child vehicle of claim 1 , wherein the child vehicle is a tricycle.

9. The child vehicle of claim 1 , wherein the propulsion switch is mounted on a steering assembly of the child vehicle.

10. A method of operating a child vehicle, comprising:

providing the child vehicle of claim 1 ;

operating the child vehicle in the first operational mode when the propulsion switch is actively engaged by a rider of the child vehicle, wherein in the first operational mode the child vehicle is being powered by the motor of the power mechanism;

automatically transitioning from the first operational mode to the second operational mode when the propulsion switch is disengaged by the rider of the child vehicle; and

operating the child vehicle in the second operational mode, wherein in the second operating mode the child vehicle is not being powered by the motor and the child vehicle may operate without substantially any drag or resistance from the motor.

11. The method of claim 10 , further comprising:

activating the engagement mechanism to operatively couple the output gear to the drive wheel; and

deactivating the engagement mechanism to operatively decouple the output gear from the drive wheel.

12. The method of claim 11 , further comprising:

moving the one or more magnetic members from a first position to a second position when the propulsion switch is engaged by the rider of the child vehicle, wherein in the second position the wheel of the child vehicle is operatively coupled to the motor of the power mechanism so that the wheel is driven by the motor; and

moving the one or more magnetic members from the second position to the first position when the propulsion switch is disengaged by the rider of the child vehicle, wherein in the first position the wheel of the child vehicle is operatively decoupled from the motor of the power mechanism so that the wheel may rotate without substantially any drag or resistance from the motor.

13. The method of claim 12 , further comprising:

engaging the one or more magnetic members with the grooves of the drive wheel when in the first position; and

disengaging the one or more magnetic members from the grooves of the drive wheel when in the second position.
