The working principle of this kinetic energy recovery system is as follows: during deceleration or braking, the electric motor reverses its rotation to convert kinetic energy into electrical energy, which is then stored in the vehicle's battery, thus achieving kinetic energy recovery.

[0003] However, the energy recovery rate of currently available purely mechanical energy recovery systems is low, and the power generation is also low, leaving much room for improvement. Utility Model Content

The hub assembly includes a central portion, spokes located on the outer periphery of the central portion and extending radially, and a rim located outside the spokes and coaxial with the central portion. The tire assembly is fitted onto the outer side of the rim, and the tire assembly and the rim together form a cavity for containing gas. Each set of first power generation components includes a metal ball, a magnetic element, and a metal elastic coil arranged radially in sequence. The metal ball is movably confined within the cavity.

[0033] Explanation of main component symbols

[0034]

[0035] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0036] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] It should be noted that when a component is described as "fixed to" or "mounted to" another component, it can be directly on the other component or may be interspersed with an intermediate component. When a component is described as "set to" another component, it can be directly set on the other component or may be interspersed with an intermediate component. The term "and / or" as used herein includes all and any combination of one or more of the associated listed items.

[0038] Please see Figures 1 to 4 This application provides a self-generating wheel structure 100, which includes a tire assembly 1, a hub assembly 2, and multiple sets of first power generation components 3. The hub assembly 2 includes a central portion 21, spokes 22 extending radially Y from the outer periphery of the central portion 21, and a rim 23 located outside the spokes 22 and coaxial with the central portion 21. The tire assembly 1 is fitted onto the outside of the rim 23, and the tire assembly 1 and the rim 23 together form a cavity 4 for containing gas. The first power generation components 3 can convert the kinetic energy generated by the wheel structure 100 during movement into electrical energy.

[0039] Each set of the first power generation components 3 includes: a metal ball 5, a magnetic element 6, and a metal elastic coil 7 arranged sequentially along the radial direction Y. The metal ball 5 is movably confined within the cavity 4. The rim 23 has a through hole 24 corresponding to the metal ball 5, communicating with the cavity 4. The magnetic element 6 passes through the through hole 24 and can move radially Y. The two ends of the metal elastic coil 7 respectively abut against the magnetic element 6 and the center portion 21, and the metal elastic coil 7 can be electrically connected to the power storage module 200 (in conjunction with...). Figure 13 (As shown).

[0040] The first power generation component 3 further includes a guide rod 8 disposed at the central portion 21 and extending radially outward along the Y direction. The metal elastic coil 7 is sleeved on the guide rod 8, and the magnetic element 6 is disposed at the end of the guide rod 8 away from the central portion 21, and the magnetic element 6 is movable along the guide rod 8. That is, one end of the guide rod 8 is fixed to the central portion 21, and the other end is a free end, on which the magnetic element 6 is sleeved. By setting the guide rod 8, the metal elastic coil 7 and the magnetic element 6 can be limited, and the coaxiality of the metal elastic coil 7 and the magnetic element 6 during operation can be improved.

[0041] In some embodiments, the magnetic element 6 has a limiting groove 61 with an opening facing the center portion 21 at one end near the center portion 21, and the guide rod 8 extends into the limiting groove 61. After being pressed by the metal ball 5, the magnetic element 6 moves along the guide rod 8, and the depth of the limiting groove 61 is set according to the formation of the radial Y movement of the magnetic element 6.

[0042] Please refer to the following: Figures 5 to 7 As shown, the rim 23 has multiple posts 25 on its surface near the cavity 4, and each pair of adjacent posts 25 has a limiting ring 26. The metal ball 5 is confined within the limiting ring 26. By setting the limiting ring 26 inside the cavity 4, the range of motion of the metal ball 5 can be limited, ensuring that the metal ball 5 contacts the end face of the magnetic component 6 and does not come out or deviate during force-driven movement.

[0043] In some embodiments, the limiting ring 26 includes two interlocking annular portions. These two annular portions are detachably connected to two adjacent posts 25 and form a ring within which the metal ball 5 is located. Each annular portion has an inner surface that conforms to the outer surface of the metal ball 5, allowing the metal ball 5 to move freely within the limiting ring 26. Furthermore, to avoid restricting the movement of the metal ball 5, the inner diameter of the limiting ring 26 is larger than the outer diameter of the metal ball 5.

[0044] Please refer to it again. Figures 5 to 7 As shown, the magnetic component 6 includes a magnetic part 62 and a sealing part 63 located at the end of the magnetic part 62 away from the center part 21. The sealing part 63 is movably sealed at the through hole 24. That is, the sealing part 63 is sealed inside the through hole 24. After being subjected to force, the sealing part 63 can reciprocate along the radial direction Y, and will never fall out of the through hole 24 during the movement, thus ensuring the sealing performance. By setting the sealing part 63, the force received by the metal ball 5 can be smoothly transmitted to the magnetic part 62, and the cavity 4 can also be sealed to prevent air leakage from the wheel-shaped structure 100.

[0045] In some embodiments, the sealing portion 63 may be made of rubber, which can improve sealing performance. The magnetic portion 62 may be a magnet. The magnetic portion 62 and the sealing portion 63 in the magnetic component 6 may be an integral structure, and the sealing portion 63 may be formed by injection molding rubber onto the end of the magnetic portion 62.

[0046] Please refer to it again. Figures 5 to 7 As shown, a fixing sleeve 27 is provided on the side of the rim 23 near the center portion 21. The fixing sleeve 27 is located outside the through hole 24, and the magnetic component 6 is movably limited within the fixing sleeve 27. By providing the fixing sleeve 27, the magnetic component 6 can be further limited, improving the stability of the magnetic component 6 during movement and enhancing the coaxiality of the magnetic component 6 and the metal elastic coil 7. In addition, the fixing sleeve 27 does not obstruct the movement of the magnetic component 6.

[0047] In some embodiments, the fixing sleeve 27 and the wheel rim 23 are an integral structure.

[0048] The metal elastic coil 7 can be electrically connected via a wire. The metal elastic coil 7 can be a metal spring coil, such as a copper coil. Figure 8 As shown, the metal elastic coil 7 has a certain length, and the section near the magnetic component 6 forms a lever arm. The existence of this lever arm can ensure that the force passes through the center of mass of the metal ball 5 when the metal ball 5 is subjected to forces in different directions, by adjusting the direction of the force. This improves the sensitivity of the first power generation component 3, which can convert forces in different directions into electrical energy and improve the mechanical energy recovery rate.

[0049] Please refer to it again. Figures 1 to 4 As shown, kinetic energy recovery can be achieved by adjusting the number and layout of the first power generation components 3. The density of the first power generation components 3 is controlled by adjusting the angle between two adjacent first power generation components 3, and this angle is set under the premise that the two adjacent first power generation components 3 do not interfere with each other when operating. In addition, the number of first power generation components 3 depends on the size of the wheel hub assembly 2. With a fixed size of the wheel hub assembly 2, arranging the most first power generation components 3 can achieve full recovery of kinetic energy.

[0050] In some embodiments, multiple sets of first power generation components 3 are arranged circumferentially along the hub assembly 2.

[0051] Please see Figure 9 and Figure 10 As shown, please refer to the following: Figure 3 and Figure 4As shown, the tire assembly 1 includes a tire 11 and a second power generation assembly 12. The tire 11, from the outside to the inside, includes a rubber layer 13, a functional layer 14, and an airtight layer 15. Multiple piezoelectric elements 16 are distributed in the functional layer 14, and the piezoelectric elements 16 can be electrically connected to the power storage module 200 (in conjunction with...). Figure 12 (As shown). The second power generation component 12 has higher mechanical strength and higher power output.

[0052] In some embodiments, the functional layer 14 may be multi-layered, and the second power generation component 12 may be arranged between any two adjacent layers of the multi-layered functional layer 14. For example, the functional layer 14 may include, from the outside to the inside, a nylon belt layer (not shown), a steel wire layer (not shown), and a ply layer (not shown), etc. The second power generation component 12 may be distributed between any two adjacent layers of the nylon belt layer, the steel wire layer, the ply layer, and the airtight layer 15. By placing the second power generation component 12 inside the nylon belt layer and outside the airtight layer 15, the sensitivity of pressure sensing can be ensured without affecting the airtightness of the tire 11, thereby improving the service life of the tire 11.

[0053] In some embodiments, the piezoelectric element 16 may be a piezoelectric ceramic sheet or a PVDF film.

[0054] In some embodiments, such as Figure 2 , Figure 9 and Figure 10 As shown, the multiple piezoelectric elements 16 in the second power generation assembly 12 can be arranged in an array. Specifically, multiple rows of piezoelectric elements 16 can be arranged along the width direction of the tire 11 so that the deformation occurring at different positions of the tire 11 can be fully converted into electrical signals, which are then electrically connected to each other and led out through wires.

[0055] In some embodiments, such as Figure 2 As shown, the second power generation component 12 may further include a support layer, on which multiple piezoelectric elements 16 may be arranged in an array. Multiple piezoelectric elements 16 can be pre-fixed to the support layer before being installed into the tire 11, facilitating installation. Specifically, the support layer may be one of the multiple functional layers 14.

[0056] The self-generating wheel structure 100 provided in this application embodiment firstly has piezoelectric elements 16 distributed throughout the inner layer of the tire 11. When the tire 11 comes into contact with the ground or a foreign object, it deforms. When the tire 11 rotates and moves away from the ground or foreign object, the deformation returns to its original state. This process transmits the deformation to the piezoelectric elements 16, thereby changing the magnetic field lines to generate electricity. Secondly, utilizing the deformation characteristics of the tire 11, the deformation is transmitted to the internal metal ball 5. The metal ball 5 pushes the magnetic element 6, changing the magnetic field lines in the metal elastic coil 7, thus generating electricity through the Faraday principle of electromagnetic induction. The specific self-generating process of this wheel structure 100 is as follows:

[0057] like Figures 11 to 13 As shown, during the movement of the wheel structure 100, when the tire assembly 1 is subjected to force, on the one hand, the tire 11 deforms under the force and squeezes the piezoelectric element 16. The piezoelectric element 16 converts the mechanical force (such as pressure, tension, or acceleration) into a measurable voltage, thereby generating electrical energy and storing it through the power storage module 200. On the other hand, the force on the tire assembly 1 is transmitted to the metal ball 5, causing the metal ball 5 to push the sealing part 63 in contact with it. The sealing part 63 further pushes the magnetic part 62, causing the magnetic part 62 to approach and compress the metal elastic coil 7. According to Faraday's law of electromagnetic induction, current is generated, realizing the power generation process. Since the metal elastic coil 7 is electrically connected to the power storage module 200, the generated electricity is ultimately stored in the power storage module 200.

[0058] Combination Figure 2 and Figure 13 As shown, when the force on tire assembly 1 is removed, on the one hand, tire 11 is no longer under force. At this time, piezoelectric element 16 returns to its initial state and converts mechanical force (such as pressure, tension, or acceleration) into a measurable voltage again, thereby generating electrical energy and storing it through power storage module 200. On the other hand, the elastic force of metal elastic coil 7 pushes magnetic part 62, sealing part 63, and metal ball 5 back to their initial state. At this time, magnetic part 62 moves away from metal elastic coil 7, and current is generated again according to Faraday's law of electromagnetic induction, realizing the power generation process again.

[0059] This application proposes a novel mechanical kinetic energy recovery concept. It utilizes the deformation of the tire 11 during driving or the gravitational changes during rotation to drive the internal first power generation component 3 and second power generation component 12, converting mechanical energy into electrical energy to provide additional power for the electric vehicle. By setting multiple sets of first power generation components 3, the wheel structure 100 can fully convert the mechanical energy generated during movement into electrical energy for storage, achieving self-generation. The mechanical energy conversion rate is high, effectively increasing power generation and realizing full and efficient recovery and utilization of kinetic energy. Furthermore, the first power generation component 3 has a simple structure, and its operation is not limited by the direction of force, enabling it to fully convert forces from all directions. In addition, by setting the second power generation component 12 in the tire 11, mechanical energy can be further converted into electrical energy. This second power generation component 12 has high mechanical strength and high power output, further achieving full recovery of mechanical energy.

[0060] Therefore, this application combines the first power generation component 3 and the second power generation component 12, that is, combines the coil power generation technology based on the Faraday electromagnetic induction principle with the piezoelectric element power generation system of compression mode, which can improve the power generation efficiency of the wheel structure 100, achieve the recovery and utilization of excess kinetic energy, and realize the effect of energy saving and carbon reduction.

[0061] Please see Figure 13 As shown in the illustration, this application also provides a vehicle 1000 utilizing the self-generating wheel structure 100. The vehicle 1000 includes a frame 300, a power storage module 200, and the self-generating wheel structure 100 mounted on the frame 300, wherein the self-generating wheel structure 100 is electrically connected to the power storage module 200. By employing the aforementioned self-generating wheel structure 100, the kinetic energy generated during the operation of the vehicle 1000 can be fully converted into electrical energy and stored for reuse by the vehicle 1000, effectively improving energy efficiency. For example, the vehicle 1000 can be an electric vehicle, but is not limited to this.

[0062] Specifically, the self-generating wheel structure 100 is not only suitable for electric vehicles, but can also be applied to any vehicle with wheels or that can rotate, such as cargo trucks, wheeled robots, and tracked systems.

[0063] Although this application discloses the above embodiments, they are not intended to limit this application. Any existing similar technical solutions may be modified and refined without departing from the spirit and scope of this application. Therefore, the scope of patent protection of this application shall be determined by the scope of the patent application attached to this specification.
