Background Technology

[0003] This application relates to personal mobile devices, and more particularly to personal mobile devices capable of generating electricity during use.

[0004] Personal mobile devices are used to transport users from one place to another. With the advent of electric personal mobile devices, many users expect these devices to have power-operated functions such as lighting, phone connectivity, speakers, or other similar features. These functions are typically powered by a battery system associated with an electric motor that drives the wheels of the personal mobile device. However, batteries provide limited power, and charging them can take a long time. In other cases, such as on unpowered scooters, bicycles, or other personal mobile devices, it may be desirable to provide lighting or other functions without using batteries. Providing such functionality in a way that does not solely rely on battery power can be a challenge. Summary of the Invention

However, the subject matter can be embodied in many different forms, and therefore, the covered or claimed subject matter is intended to be construed as not being limited to any of the exemplary embodiments set forth herein; the exemplary embodiments are for illustrative purposes only. It should be understood that other embodiments may be used and structural changes may be made without departing from the scope of these exemplary embodiments. Similarly, the covered or claimed subject matter is intended to have a reasonably broad scope. Throughout the specification and claims, terms may have subtle meanings implied or implied in the context that go beyond the meanings explicitly stated. Likewise, "in one embodiment" as used herein does not necessarily refer to the same embodiment, and "in another embodiment" does not necessarily refer to different embodiments. For example, the claimed subject matter is intended to include all or part of the exemplary embodiments. Among other things, the subject matter may be embodied as a method, apparatus, component, or system. Therefore, embodiments may take the form of, for example, hardware, software, firmware, or any combination thereof (except for the software itself). Therefore, the following detailed description is not intended to be construed in a limiting sense.

[0048] refer to Figures 1 to 14 An exemplary embodiment of a personal mobile device 100 is disclosed. The personal mobile device 100 is configured to provide a user with personal mobility functions, such as personal transportation functions that transport the user from one location to another. In one illustrative embodiment, the personal mobile device 100 includes a scooter, for example, as... Figure 1 As shown. In other embodiments, the personal mobile device 100 may include other devices that can be used to transport a user, including bicycles, skateboards, unicycles, hoverboards, tricycles, tricycle devices, ride-on toys, strollers, trolleys, or any other personal mobile device. In one illustrative embodiment, the personal mobile device 100 is configured to generate electrical energy using physical forces applied by the user during use of the device, to power load components such as lighting elements, speakers, battery charging devices, or any other load components configured to utilize electrical energy.

[0049] refer to Figures 1 to 4 In one exemplary embodiment, the personal mobile device 100 includes a handlebar 110, a pole 120, a folding mechanism 130, a support structure 140, wheels 160 and 162, and a power generation device 170. In other embodiments, other configurations may be employed, including, for example, alternative folding mechanisms 130, multiple support structures 140, more or fewer wheels 160 / 162, or any other alternative components or configurations.

[0050] The upright 120 includes a rod body 122 that inserts into the steering column 124. In some embodiments, the rod body 122 may be secured to the steering column 124 by a clamp or other mechanism to prevent rotation, linear movement, or both relative to the steering column 124. In some embodiments, linear movement of the rod body 122 relative to the steering column 124 may also be limited by other mechanisms, such as engagement of a locating pin on the rod body 122 with a recess or hole on the steering column 124, or by other possible combinations. For example, a spring-loaded locating pin on the rod body 122 may be configured to pass through a hole in the steering column 124 to prevent linear movement of the rod body 122 relative to the steering column 124. In some embodiments, the steering column 124 may include a plurality of holes with which a locating pin may engage to adjust the height of the handlebar 110 relative to the wheel 160.

[0051] The steering column 124 includes one or more flanges 126 that are secured to the wheel 160 in a manner that allows the wheel 160 to rotate. For example, an axle or other component may engage with or pass through the wheel 160 and be secured to the flange 126, wherein the wheel 160 is configured to rotate about the axle or other component. Other mechanisms for securing the wheel 160 to the steering column 124 may also be employed. In one illustrative embodiment, rotating the steering column 124 via the handlebar 110 through the lever 122 is configured to cause a corresponding rotation of the wheel 160 to change the direction of travel. In other embodiments, any other mechanism may be employed to rotate or adjust the wheel 160 to change direction.

[0052] Folding mechanism 130 connects support structure 140 to steering column 124. For example, folding mechanism 130 may include strut 132 and hinge 134, or any other folding mechanism may be used. Figures 1 to 4 As shown, the strut 132 includes a shaft 136 into which a steering column 124 is inserted, allowing the steering column 124 to rotate relative to the shaft 136. A clamp 128 or other structure is used to prevent linear movement of the shaft 136 relative to the steering column 124. For example, the clamp 128 may be fixed above the shaft 136 on the steering column 124 to suppress linear movement of the shaft 136 relative to the steering column 124.

[0053] Hinge 134 is fixed to support structure 140 and configured to allow support structure 140 to rotate relative to steering column 124, for example, about pivot point 136 or other portions of hinge 134. For example, strut 132 is configured to hinge to hinge 134 such that strut 132 rotates about hinge 134, for example, along a channel, axis, pivot point 136, or other mechanism in hinge 134. While personal mobile device 100 in Figures 1 to 4 The illustrated embodiments are described and shown to include a folding mechanism 130, but in an alternative embodiment, the personal mobile device 100 does not include a folding mechanism 130, in which case the support column 132 or similar component can be directly attached to the support structure 140 without first connecting to the hinge 134.

[0054] refer to Figures 1 to 14 The support structure 140 includes a support member 142, a side member 144, and a side member 146. A platform 148 is secured to the support member 142, the side member 144, and the side member 146. The support member 142 may include, for example, a strut, a tube, a support frame, or any other component configured to provide structural support to the side member 144, the side member 146, and the platform 148. In some embodiments, the platform 148 may also be referred to as a pedal 148 and is configured to support a user, for example, a user standing on the platform 148 while using the personal mobile device 100. In other embodiments or for other types of personal mobile devices 100 (e.g., bicycles), the support structure 140 may include one or more support members, struts, tubes, support frames, or other components that connect wheels 160 and 162 together directly or via one or more additional components of the personal mobile device 100. For example, the support structure 140 connects wheel 160 to wheel 162 via a steering column 124 and a folding mechanism 130. In embodiments where the personal mobile device 100 includes a bicycle, the support structure may connect the wheels together via one or more supports, struts, tubes, support frames or other components, and in some embodiments, may support other components besides the platform 148, such as a seat.

[0055] In some embodiments, one or more of the support member 142, side member 144, side member 146, and platform 148 may include one or more load assemblies 149. Figures 6 to 9 and Figure 21 Examples include lighting elements, speakers, battery charging devices, or any other load components configured to utilize electrical energy generated by the power generation device 170. (See reference...) Figures 6 to 9As an example, lighting element 147 may be connected to side members 144 and 146 and connected to power generation device 190 via line 151. Lighting element 147 may include, for example, a light-emitting diode (LED) or any other form of lighting. Line 151 may, for example, electrically connect generator 174 to circuit board 175 and connect circuit board 175 to lighting element 147 via support member 142 to power lighting element 147. In some embodiments, other components of personal mobile device 100 may also include load assembly 149, including, for example, handlebars 110, pole 120, folding mechanism 130, and wheels 160 and 162.

[0056] The support structure 140 also includes a bracket 150 connected to one of the support member 142 or the side members 144, 146, and a distal portion 152. The bracket 150 is configured to keep the personal mobile device 100 upright without user assistance when the user is not using the personal mobile device 100.

[0057] The distal portion 152 is configured to engage and support the wheel 162, allowing the wheel 162 to rotate relative to the support structure 140. For example, the distal portion 152 may include one or more flanges 154, to which a shaft or other component may engage or pass through the wheel 162 and be secured, wherein the wheel 162 is configured to rotate about the shaft or other component. Other mechanisms for securing the wheel 162 to the support structure 140 may also be employed.

[0058] Optionally, a mudguard 156 extends from the distal portion 152 and is configured to prevent dirt or other debris from the ground from splashing onto the user as the personal mobile device 100 moves.

[0059] The support structure 140 also includes a housing 190, attached to the distal portion 152 and adjacent to the wheel 162, configured to support a power generation device 170. The power generation device 170 is configured to generate electrical energy at least partially based on the rotation of the wheel 162. In some embodiments, the power generation device 170 is detachably attached to the housing 190. For example, the power generation device 170 may be detachably or fixedly housed within the housing 190. In one embodiment, the housing 190 is secured to the support structure 140 by a bracket 192 and is located below a portion of the platform 148 covering the distal portion 152. In other embodiments, the housing 190 may be formed as part of the support 142 or attached to any other part of the personal mobile device 100. For example, in some embodiments, the housing 190 or the power generation device 170 itself may be attached to the axle of the wheel 162 or to other components of the personal mobile device 100.

[0060] refer to Figures 6 to 14The power generation device 170 includes a housing 172, a generator 174, and a biasing member 176. The housing 172 includes housing assemblies 172A and 172B, coupled together to partially enclose the generator 174 while exposing a portion of the generator 174. The generator 174 includes a rotor 178 and a stator 180. The stator 180 is mounted on a shaft 182 of the housing assembly 172B and engages with a corresponding channel 186 on the stator 180 via a locating pin 184 on the shaft 182 to prevent rotation relative to the housing 172. In other embodiments, the stator 180 may include locating pins, and the shaft 182 may include corresponding channels. Although described above as being contained within a housing 172, in other embodiments, any one or more of the generator 174, biasing member 176, rotor 178, and stator 180 may be interconnected or individually connected as components of the personal mobile device 100 without being contained within a housing.

[0061] In the illustrative embodiment, rotor 178 includes one or more permanent magnets, and stator 180 includes one or more winding coils. Such winding coils are as follows: Figure 19 As shown in the embodiment, one or more wires 288 are wound around the teeth 289 of the stator 280 (by way of example). For the sake of brevity, Figure 19 The entire conductor 288 wound around the tooth 289 is not shown. Any known type of winding coil can be used. Examples of permanent magnets that can be used in the generator 174 include ceramic, AlNiCo, ferrite, Samarium Cobalt, Neodymium Iron Boron, or any other type of permanent magnet. In other embodiments, the rotor 178 may include winding coils, while the stator 180 may include permanent magnets. In some embodiments, both the rotor 178 and the stator 180 may include winding coils.

[0062] Although generator 174 is described as including a rotor and a stator, any other type of generator configured to convert mechanical energy input into electrical energy output may also be used. In some embodiments, generator 174 is an alternating current generator, such as an alternating current (AC) generator. In some embodiments, generator 174 may be configured to produce a direct current (DC) output.

[0063] The biasing member 176 includes a spring, shape memory material, or any other biasing member that can be used to bias the housing 172 and the generator 174 toward the wheel 162. Figure 8As shown, for example, a biasing member 176 (e.g., a spring) abuts at one end against a portion of the housing 190 of the support structure 140 and at the other end against a portion of the housing 172 to bias the housing 172 and the generator 174 toward the wheel 162, causing the rotor 178 to contact and frictionally engage with the wheel 162. In an illustrative embodiment, when the wheel 162 rotates due to its own physical force during user use of the personal mobile device 100, the frictional engagement between the wheel 162 and the rotor 178 causes the rotor 178 to rotate accordingly around the stator 180. The rotation of the rotor 178 around the stator 180 generates a current in the winding coils of the stator 180, which can be used to power a load (e.g., load assembly 149). In some embodiments, the biasing member 176 may be configured to selectively bias the generator 174 toward the wheel 162. For example, biasing member 176 may include a user actuation mechanism that configures biasing member 176 to apply bias to the generator 174 towards the wheel 162, or to de-bias the generator 174 towards the wheel 162. In some embodiments, biasing member 176 may be omitted or used weakly, and generator 170 may alternatively be positioned above wheel 162, utilizing gravity to engage generator 174 with wheel 162. In some embodiments, biasing member 176 may alternatively bias generator 174 towards other rotating parts of personal mobile device 100 (e.g., shafts) or any other part of personal mobile device 100 for frictional engagement or other forms of engagement. In some embodiments, biasing member 176 may alternatively bias generator 174 towards frictional engagement with a surface outside personal mobile device 100 (e.g., the ground).

[0064] refer to Figures 12 to 14 The power generation device 170 is configured to be removably inserted into the chamber 194 of the housing 190. In some embodiments, for example, the power generation device 170 includes locating pins or flanges 188 that, when the power generation device 170 is inserted into the chamber 194, are configured to engage channels 196, 198 around corresponding flanges 199 on the housing 190, such that the power generation device 170 can slide linearly along the flanges 199 relative to the chamber 194. Figure 8 As shown, when the power generation device 170 is inserted into the chamber 194 of the housing 190, the biasing member 176 engages with the housing 190 to bias the power generation device 170 toward the wheel 162. In some embodiments, such as... Figure 8As shown, the biasing member 176 can be configured to engage with and partially surround the locating pin 191 of the housing 190, for example, to prevent the biasing member 176 from deviating from the axis during linear movement of the generator 170. In other embodiments, other methods may be used to detachably, semi-permanently, or permanently insert or attach the generator 170 to the housing 190 or the support 142, including, for example, pressure fit, ratchet, adhesive, snap ring, strap, snap fastener, or any other connection method.

[0065] Combined with appendix Figures 15 to 20 An exemplary embodiment of a personal mobile device 200 is disclosed. The personal mobile device 200 is similar to the personal mobile device 100, and where possible, similar reference numerals will be used to denote similar components. For the sake of brevity, Figures 15 to 18 The remote portion of a personal mobile device 200 is shown. It should be understood that the personal mobile device 200 may include components similar to... Figures 1 to 4 The scooter, bicycle, skateboard, or any other type of personal mobile device shown and described. For the sake of brevity, components in personal mobile device 200 similar to those in personal mobile device 100 described above will not be described in detail. Instead, only the differences between personal mobile device 200 and personal mobile device 100 will be described.

[0066] like Figure 15 and Figure 16 As shown, the personal mobile device 200 includes a support structure 242, a housing 290, a power generation device 270, and wheels 262.

[0067] The support structure 242 includes one or more flanges 254 configured to engage and support the wheel 262, for example, as described above for flange 154. Furthermore, the support structure 242 includes a chamber 243 and a channel 255, both configured to receive at least a portion of the housing 290. In some embodiments, for example, the housing 290 is configured to slide linearly into the chamber 243 via engagement of the flanges 292 on the outer surface of the housing 290 with the channel 255.

[0068] The housing 290 also includes a chamber 294, a locating pin 291, and flanges 299 on its inner surfaces. Each flange 299 on its inner surface defines a channel 296 configured to accommodate a corresponding flange 288 on the outer surface of the housing assemblies 272A, 272B of the housing 272 when the power generation device 270 is inserted into the chamber 294. For example, in some embodiments, the flange 288 is inserted into the channel 296 while simultaneously engaging with the flange 299 of the housing 290, thereby enabling sliding of the power generation device 270 relative to the housing 290. A biasing member 276 is configured to engage with the locating pin 291 in a manner similar to that of the biasing member 176 and the locating pin 191. As described above, in this manner, the power generation device 270 is configured to be removably inserted into the housing 190, and the housing 190 is configured to be removably inserted into the support structure 242. In other embodiments, other methods may be used to detachably, semi-permanently, or permanently insert or attach the power generating device 270 to the housing 290 or the support structure 242, including, for example, pressure fitting, ratchet, adhesive, buckle, strap, snap-fit ​​connection, or any other connection method.

[0069] Refer again Figures 15 to 20 The power generation device 270 includes a housing 272, a generator 274, and a biasing member 276. The generator 274 includes a rotor 278 and a stator 280, similar to the generator 174 described above. Figures 15 to 20 The internal components of the stator 280 are also shown, including wires 288 and teeth 289 as described above. In some embodiments, the stator 280 may be fixed as part of the housing 272. In other embodiments, locating pins and channels may be used to prevent the stator 280 from rotating relative to the housing 272, as described above with reference to the stator 180 and housing 172.

[0070] refer to Figure 21 The following describes a block diagram of an exemplary electrical system 300 for a personal mobile device 100. A similar electrical system can also be used for a personal mobile device 200. For example... Figure 21As shown, the power generation device 170 is electrically connected to the circuit 302 and the load component 149 via one or more wires 304. In some embodiments, the circuit 302 may be an optional configuration, as shown by the dashed line; for example, the power generation device 170 may be directly electrically connected to one or more load components 149 via the wires 304. In one embodiment, the electrical system 300 may optionally include an electrical storage component 306 configured to supply power to the load component 149 and be charged by the power generation device 170 and the circuit 302. In some embodiments, the electrical system 300 may supply power to the load component 149 via the electrical storage component 306, the power generation device 170, or both simultaneously, for example, in parallel or combined manner. For example, in cases where a larger voltage or current is required, the output charge of the electrical storage component 306 may be supplemented by the output of the power generation device 170. In some embodiments, the electrical storage component 306 may include a battery, one or more capacitors, or any other electrical storage component.

[0071] In some embodiments, the power generation device 170 can be connected directly to an external output port 308 via wire 304 or via circuit 302. The external output port 308 may include, for example, a port, plug, or any other connection that can be plugged into another device. In some embodiments, the external output port 308 may include a wireless power transmitter configured to wirelessly transmit power to a wireless power receiver in another device detached from the personal mobile device 100. For example, the wireless power transmitter may include a transmission coil or other mechanism for wirelessly transmitting power, while the other device may include a receiving coil. A mobile phone is an example of a device detached from the personal mobile device 100 that may include a wireless power receiver. In some embodiments, the external output port 308 may include wired and wireless connections, including, for example, a port, plug, socket, wireless power transmitter, or any other component configured to provide electrical energy generated by the power generation device 170 to another device detached from the personal mobile device 100. In other embodiments, any other configuration or electrical system 300 may be used to connect the power generation device 170 to the load component 149 or to other devices via the external output port 308.

[0072] refer to Figure 22An exemplary electrical diagram of circuitry 302 that can be used to process the output of generator 174 will be described below. Similar circuitry can also be used for generator 274. Circuitry 302 includes various circuit components, including, for example, resistors, capacitors, diodes, coils, processing devices, transistors or other semiconductor devices or any other electrical components. In some embodiments, for example, circuitry 302 is configured to perform voltage regulation to stabilize and adjust the output voltage of stator 180 to achieve a target voltage for a particular load application. For example, circuitry 302 may include voltage regulator components such as linear voltage regulators, switching voltage regulators, low dropout regulators (LDOs), boost switching regulators, buck switching regulators, boost / buck switching regulators, or any other type of voltage regulator. In one example, circuitry 302 may be configured to regulate the voltage output to a particular load, for example, to a particular voltage level, current level, or in any other way. In some embodiments, other circuitry may also be employed depending on the specific load component 149.

[0073] The personal mobile device 100 (and 200) described in this application is capable of transferring the rotational kinetic energy of the wheels 162 generated when a user uses the personal mobile device 100 (e.g., by kicking, dragging, running, pushing, or otherwise driving the personal mobile device 100, thereby causing the wheels 162 to rotate) to the generator 174 via direct frictional contact between the rotor 178 of the generator 174 and the wheels 162. The rotor 178 then transfers the energy to the stator 180 via magnetic coupling to generate a current output that can be used to power one or more load components 149, such as lighting elements, speakers, batteries, or any other load device.

[0074] Although this application is described with respect to personal mobile devices 100, 200 and wheels 162 / 262, the power generation device 170 / 270 can also be used alternatively with any other personal mobile device and any other wheel or other rotating component to generate electricity. For example, in another embodiment, the power generation device 170 can be used with wheel 160 to generate current based on the rotation of wheel 160. For example, in another embodiment, housing 190 can be configured to be fixed to steering column 124, for example, in a manner similar to how housing 190 is fixed to support member 142 or housing 290 is fixed to support structure 242, such that rotor 178 is biased into contact with wheel 160.

[0075] In some embodiments, wheels 160 and 162 may each have a corresponding power generation device 170, wherein the output current can be combined or used individually to power multiple load components 149 at various locations on the personal mobile device 100 / 200. For example, in one embodiment, the power generation device 170 engaged with wheel 160 can power load components 149 located on handlebar 110, post 120, support column 132 of folding mechanism 130, and wheel 160, while the power generation device 170 engaged with wheel 162 can power load components 149 located on support 142, hinge 134 of folding mechanism 130, and wheel 162. In other embodiments, the power generation device 170 engaged with wheel 160 can power load components 149 located on any part of the personal mobile device 100 / 200, and the power generation device 170 engaged with wheel 162 can also power load components 149 located on any part of the personal mobile device 100 / 200. In some embodiments, for example, in the presence of additional wheels or other rotating components, each wheel or rotating component may optionally have a corresponding power generation device 170 configured to power one or more load components 149 of the personal mobile device 100 / 200.
