Specification

TECHNICAL FIELD
[001] The present disclosure relates to the field of vehicles, more particularly, the
present disclosure relates to self-balancing unicycles.
BACKGROUND
[002] Background description includes information that may be useful in understanding
the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] Vehicles such as cars and motorcycles were invented to increase travel speed and,
in-turn, reduce travel time for the user. But, with rise in number of vehicles, traffic congestion in many cities has become a common phenomenon along with serious environmental pollution caused due to traffic congestion. Out of number of vehicles in city, most number of vehicles is used by commuters for commuting for short distance. Also, since vehicles are limited to travel on road and width of road can be increased only up to certain extent inside city limits, therefore size of vehicles needs to be optimized to allow easy travelling. One such alternative can include a unicycle.
[004] Unicycles typically have a seat upon which a rider may sit and operate pedals
coupled to the wheel or other means such as electric motors to propel the unicycle. Riders of the unicycles must maintain stability by managing both their sideways balance and forward and backward balance while travelling straight and turning. Forward and backward balance on the unicycle is managed by speeding the wheel up or slowing the wheel down in order to maintain the wheel point-of-contact under the centre of gravity (COG) of the rider. However, beginners find it very difficult to balance the unicycle.
[005] There is therefore, need in the art, to design an improved and efficient but reliable
self-balancing electric unicyclethat fulfils the aforementioned needs and also addresses the inefficacy available in the devices and techniques of prior-art. Further, there is also a need to provide an improved unicycle that can help reduce traffic congestion and pollution.
OBJECTS OF THE PRESENT DISCLOSURE
[006] It is a general object of the present disclosure to provide an improved self-
balancing unicycle that enables fast and easy transportation of the user.

[007] It is an object of the present disclosure to provide a self-balancing unicycle that
limits pollution emission by vehicles.
[008] It is an object of the present disclosure to provide a self-balancing uni cycle that
provides alternative commuting vehicle with reduced size.
[009] It is another object of the present disclosure to provide a self-balancing uni cycle
that provides automatic balancing of uni cycle when the uni cycle is stationary or in motion.
[0010] It is yet another object of the present disclosure to provide a self-balancing vehicle
that can be operated on every surface for example smooth, slippery, slant, bumpy and the like.
SUMMARY
[0011] The present disclosure relates to the field of vehicles, more particularly, the present disclosure relates to self-balancing unicycles.
[0012] In an aspect, the present disclosure provides a self-balancing unicycle. The
unicycle includes a wheel hub assembly. The wheel hub assembly includes a wheel hub
coupled to a wheel of the unicycle; a primary electric motor coupled to the wheel hub for
transmitting rotary motion to the wheel; a secondary electric motor; and a flywheel coupled to
the secondary electric motor. The secondary electric motor rotates the flywheel at a specific
speed. Selective rotation of the primary motor in different direction provides forward and
backward balancing of said unicycle, and wherein rotation of the flywheel turns the wheel in a
direction of tilting of the unicycle and generates a counter force in a direction that is opposite
to tilting of the unicycle to provide balancing of said unicycle in side-way direction.
[0013] Further, the counter force generated by the rotation of the flywheel is due to
gyroscopic effect. The primary electric motor and the secondary electric motor are located around a primary motor shaft and a secondary motor shaft respectively, wherein the primary motor shaft and a secondary motor shaft are stationary shaft. The primary electric motor and the secondary electric motor are hub motors/wheel hub motors. The unicycle includes a mounting frame having a first arm and a second arm and spaced apart in lateral direction of the unicycle, wherein the first arm and the second arm are coupled to the primary motor shaft and the secondary motor shaft. In an embodiment, the primary motor shaft and the secondary motor shaft are stationary.
[0014] Furthermore, the unicycle comprises a seat mounted on the mounting frame to
accommodate a user. The unicycle includes a steering mechanism for directing the wheel of the unicycle in a specific direction, wherein the steering mechanism comprises a handle coupled to the mounting frame with assistance of a rack and pinion mechanism. The unicycle

includes a plurality of sensors such as an accelerometer, a gyro-sensor, a hall-effect sensor and the like to sense parameters of the primary electric motor and secondary motor, position of the unicycle and gesture of the user; and a controller to control speed and direction of rotation of the primary electric motor and the secondary electric motor based on input from the plurality of sensors. Also, motion of the unicycle in a forward direction or in a backward direction is controlled by the controller based on gesture of the user accommodated on the seat, as sensed by any of the plurality of sensors. The unicycle is powered by one or more power storage devices configured with the mounting frame.

[0040] The present disclosure relates to the field of vehicles, more particularly, the present disclosure relates to self-balancing unicycles.
[0041] In an aspect, the present disclosure provides a self-balancing unicycle. The
unicycle includes a wheel hub assembly. The wheel hub assembly includes a wheel hub
coupled to a wheel of the unicycle; a primary electric motor coupled to the wheel hub for
transmitting rotary motion to the wheel; a secondary electric motor; and a flywheel coupled to
the secondary electric motor. The secondary electric motor rotates the flywheel at a specific
speed. Selective rotation of the primary motor in different direction provides forward and
backward balancing of said unicycle, and wherein rotation of the flywheel turns the wheel in a
direction of tilting of the unicycle and generates a counter force in a direction that is opposite
to tilting of the unicycle to provide balancing of said unicycle in side-way direction.
[0042] Further, the counter force generated by the rotation of the flywheel is due to
gyroscopic effect. The primary electric motor and the secondary electric motor are located around a primary motor shaft and a secondary motor shaft respectively, wherein the primary motor shaft and a secondary motor shaft are stationary shaft. The primary electric motor and the secondary electric motor are hub motors/wheel hub motors. The unicycle includes a mounting frame having a first arm and a second arm and spaced apart in lateral direction of the unicycle, wherein the first arm and the second arm are coupled to the primary motor shaft

and the secondary motor shaft. In an embodiment, the primary motor shaft and the secondary motor shaft are stationary.
[0043] Furthermore, the unicycle comprises a seat mounted on the mounting frame to
accommodate a user. The unicycle includes a steering mechanism for directing the wheel of the unicycle in a specific direction, wherein the steering mechanism comprises a handle coupled to the mounting frame with assistance of a rack and pinion mechanism. The unicycle includes a plurality of sensors such as an accelerometer, a gyro-sensor, a hall-effect sensor and the like to sense parameters of the primary electric motor and secondary motor, position of the unicycle and gesture of the user; and a controller to control speed and direction of rotation of the primary electric motor and the secondary electric motor based on input from the plurality of sensors. Also, motion of the unicycle in a forward direction or in a backward direction is controlled by the controller based on gesture of the user accommodated on the seat, as sensed by any of the plurality of sensors. The unicycle is powered by one or more power storage devices configured with the mounting frame.
[0044] FIGs. 1A and IB illustrate an exemplary representation of proposed unicycle, in
accordance with an embodiment of the present disclosure.
[0045] In an embodiment, the proposed self-balancing unicycle 100 can include a wheel
102 for providing movement to the unicycle. A wheel 102 can be coupled to wheel hub assembly 104. Further, the unicycle 100 can include a mounting frame 106 for supporting a seat 108 mounted on the mounting frame 106. The mounting frame 106 can include a first arm and a second arm such that the first arm and the second arm can be designed on either side of the wheel 102. Also, the unicycle 100 can include a handle 110 for turning the unicycle 100. A steering mechanism can include a rack and pinion mechanism (not shown) for turning the unicycle 100 to the direction of choice.
[0046] Further, the unicycle 100 can include a plurality of sensors (not shown) such as an
accelerometer, a gyro-sensor, a hall-effect sensor and a gesture sensor, and a controller (not shown). The accelerometer can be used to sense acceleration of the unicycle 100, the gyro sensor for sensing orientation of the unicycle 100, the hall-effect sensor to sense speed of the unicycle 100 and the hall-effect sensor to detect position. The position can either be an absolute hall-effect sensor or a relative one. The hall-effect sensors can be linear, angular or multi-axial. The gesture sensor can be used to sense the gestures of the user. Further, the gestures can include plurality of events such as front inclination, no inclination or back inclination. In event of front inclination gesture of the user, the unicycle 100 accelerates or speed of the unicycle 100 is increased. In event of no inclination gesture of the user, the

unicycle 100 speed remains same. In event of backward inclination of the user, the unicycle
decelerates or the speed of the unicycle 100 is reduced.
[0047] In an embodiment, a plurality of values, as sensed by the plurality of sensors, can
be fed to the controller (not shown). Further, the controller, based on the sensed values, can
control the acceleration, braking as well as provide balancing to the unicycle 100 in front,
back and sideways direction. Also, the unicycle 100 can include one or more power storage
devices (not shown). In an embodiment, the one or more power storage devices can include a
battery for storing power that can be used to provide power to the unicycle 100.
[0048] It shall be appreciated by a person skilled in the art that, based on the plurality of
values sensed by the plurality of the sensors, the unicycle can be controlled to not topple as
well, and can be used to propel the unicycle in forward as well as backward direction.
[0049] FIGs. 2A through 2C illustrate an exemplary representation of wheel hub
assembly, in accordance with an embodiment of the present disclosure.
[0050] In an embodiment, the wheel hub assembly 104 can include a primary shaft 212
and a secondary shaft 214. A primary motor 216 can be disposed such that the primary motor
216 can be located around the primary shaft 212. The primary motor 212 can be coupled with
a wheel hub 222. A secondary motor 216 can be disposed such that the secondary motor 218
can be located around the secondary shaft 214. A flywheel 220 can be coupled with the
secondary motor. Rotary motion of the primary motor 216 can be transmitted to the wheel
hub that can be used to rotate the wheel 102. Rotary motion of the secondary motor 218 can
be used to rotate the fly wheel 220. The rotation of the flywheel 220 turns the wheel 102 in a
direction of tilting of the unicycle 100 and generates a counter force in a direction that is
opposite to tilting of the unicycle 100 to provide balancing of the unicycle 100 in side-ways
direction. The force generated by the rotation of the flywheel is due to gyroscopic effect.
[0051] For example, if the unicycle falls towards right direction then the secondary motor
218 will rotate the fly-wheel such that the wheel 102 rotates to the right to counter tilting of
the unicycle 100.
[0052] It shall be appreciated that in the proposed invention, moving forward and
backward has been explained using a wheel; however, wheel can be replaced with other
movement forms such as levitating technology and the like.
[0053] FIGs. 3 A through 3D illustrate an exemplary representation of the wheel hub, in
accordance with an embodiment of the present disclosure.
[0054] In an embodiment, the primary motor 216 and the secondary motor 218 can be
disposed, but not be limited as hub motor or wheel hub motor. The hub motor is configured

such that it can be used to directly drive the wheel 102.The hub motor can be configured such that the shaft around which the motor is disposed remains stationary, whereas the motor rotates around the shaft. In an embodiment, the primary motor 216 and the secondary motor 218 can be disposed in the wheel hub 222 such that the primary shaft 212 and the secondary shaft 214 remain stationary. Further, the primary shaft 212 and the secondary shaft 214 can be used to mount the wheel 102.
[0055] Although the proposed system has been elaborated as above to include all the main parts, it is completely possible that actual implementations may include only a part of the proposed modules/engines or a combination of those or a division of those in various combinations across multiple devices that can be operatively coupled with each other, including in the cloud. Further the modules/engines can be configured in any sequence to achieve objectives elaborated. Also, it can be appreciated that proposed system can be configured in a computing device or across a plurality of computing devices operatively connected with each other, wherein the computing devices can be any of a computer, a laptop, a smart phone, an Internet enabled mobile device and the like. All such modifications and embodiments are completely within the scope of the present disclosure.
[0056] Embodiments of the present disclosure may be implemented entirely hardware,
entirely software (including firmware, resident software, micro-code, etc.) or combining
software and hardware implementation that may all generally be referred to herein as a
"circuit," "module," "component," or "system." Furthermore, aspects of the present
disclosure may take the form of a computer program product comprising one or more
computer readable media having computer readable program code embodied thereon.
[0057] Thus, it will be appreciated by those of ordinary skill in the art that the diagrams,
schematics, illustrations, and the like represent conceptual views or processes illustrating systems and methods embodying this invention. The functions of the various elements shown in the figures may be provided through the use of dedicated hardware as well as hardware capable of executing associated software. Similarly, any switches shown in the figures are conceptual only. Their function may be carried out through the operation of program logic, through dedicated logic, through the interaction of program control and dedicated logic, or even manually, the particular technique being selectable by the entity implementing this invention. Those of ordinary skill in the art further understand that the exemplary hardware, software, processes, methods, and/or operating systems described herein are for illustrative purposes and, thus, are not intended to be limited to any particular named.

[0058] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean "communicatively coupled with" over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0059] It should be apparent to those skilled in the art that many more modifications
besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms "comprises" and "comprising" should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C .... and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
[0060] While the foregoing describes various embodiments of the invention, other and
further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable people having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
