Abstract
The present invention relates to motorized platforms wearable by a user, for enhancing the speed of walking while maintaining stability and reducing overall weight, due to a simplified structure and relatively modest number of components.
Claims20
A motorized walking system, comprising:
- two motorized walking enhancement platforms, wherein each of the two motorized walking enhancement platforms comprises:
- a base frame;
- a drive assembly attached to the base frame, the drive assembly comprising:
- a front lateral sub assembly, comprising a couple of front primary wheels affixed to both sides of a front axle;
- a rear lateral sub assembly, comprising a couple of rear primary wheels affixed to both sides of a rear axle;
- a drive line comprising:
- a motor having a motor shaft protruding longitudinally from both sides of the motor;
- a front longitudinal shaft member coupled to the motor shaft via a front speed reduction unit;
- and
- a rear longitudinal shaft member coupled to the motor shaft via a rear speed reduction unit;
- a front non-differential transmission mechanism, configured to translate rotational movement of the of the front longitudinal shaft member to rotational movement of the front axle;
- a rear non-differential transmission mechanism, configured to translate rotational movement of the rear longitudinal shaft member to rotational movement of the rear axle;
- a control circuitry configured to control at least the functionality of the motor,
- wherein the control circuitry is configured to receive feedback corresponding to the momentary rotation speed of the primary wheels, compare the momentary rotation speed to a corresponding to a pre-set rotation speed, and if the momentary rotation speed is higher or lower than the pre-set rotation speed, to provide controlling signals configured to neutralize such change by readjusting the rotation torque of the motor, so as to revert the rotation speed of the primary wheels back to the pre-set desired speed.
