Description

Technical Field

[0001] This invention relates to the fields of vehicle kinetic energy recovery power generation, rail transit power generation, and waste energy recovery from industrial rotating motors. Specifically, it relates to a levitation magnetic self-generating multi-purpose wheel flange power generation device, which is widely applicable to: bicycles, two-wheeled electric vehicles, electric tricycles, new energy electric vehicles, passenger cars, SUVs, buses, trucks, heavy trucks; trains, high-speed trains, rail transit wheel sets; various household rotating motors, industrial rotating motors, industrial transmission wheels, industrial rotating machinery equipment, and all other carrier scenarios with rotational motion. Background Technology

[0002] Existing wheeled vehicle power generation mostly relies on the recovery of kinetic energy from the vehicle's braking, generating limited power only during deceleration. It cannot continuously replenish power during normal driving, coasting, or downhill driving. Traditional triboelectric power generation relies on physical roller friction transmission, which has drawbacks such as high wear, high resistance, failure in rainy weather, easy failure, and short lifespan.

[0003] Meanwhile, existing rail transit trains and high-speed trains have huge kinetic energy from their wheels, but lack contactless continuous recovery and power generation devices; a large number of industrial motors and industrial rotating equipment operate under no-load and load conditions for long periods of time, resulting in the waste of excess rotational kinetic energy. Currently, there is a lack of a modular, contactless, externally mountable, highly versatile, and non-modifiable magnetic auxiliary power generation module that does not require modification of the main unit structure.

[0004] Furthermore, traditional exposed power generation structures generally suffer from problems such as exposure to rain, mud and water splashing, sludge accumulation, and dust contamination, which can easily lead to safety and lifespan hazards such as leakage, short circuits, coil corrosion due to moisture, and magnet rusting and demagnetization. They also lack an integrated sealed protection design that is waterproof, dustproof, mudproof, and leakage-proof for all-weather outdoor working conditions.

[0005] Based on the current iterative development of kinetic energy recovery power generation technology in the industry, existing technologies can be divided into four generations, all of which have fundamental technical defects, as follows: First generation: Physical friction contact power generation technology, relying on rigid contact transmission through mechanical components such as rollers and belts to generate electricity. It suffers from fatal defects such as severe mechanical wear, high additional driving resistance, slippage in rainy weather, high failure rate, and short service life, and has been gradually phased out by the market. Second generation: Hub-integrated magnetic induction power generation technology, integrating magnets and coils inside the hub. Although it achieves contactless power generation, it requires significant modifications to the original vehicle / equipment structure, cannot be externally mounted, has high modification difficulty and maintenance costs, and is applicable only to small conventional vehicles, unable to be applied to rail transit or large industrial rotating equipment. It also has poor waterproof performance and significant safety hazards. The third generation: External simple contactless power generation technology, which can be installed externally without major changes to the main unit structure. It adopts a preliminary air-isolated magnetic induction design and has no mechanical friction. However, the rotor needs to have an internal coil and external wiring, which poses safety risks such as entanglement, wire breakage, leakage, and short circuit. The installation and layout are limited and lack modular design. It also lacks professional waterproof, dustproof, and corrosion-resistant structures, making it extremely unsuitable for outdoor working conditions. It can only be used in ordinary small vehicles and cannot penetrate high-value fields such as new energy vehicles, rail transit, and industrial waste energy recovery. Furthermore, it lacks a fine gap adjustment and bump-adaptive structure. When the vehicle is traveling on bumpy roads, component displacement, magnetic gap disorder, collision noise, and structural damage are likely to occur. The technology has extremely strong limitations. The fourth generation: single-domain magnetic levitation wheel flange power generation technology. Compared with the third generation, the magnetic field stability and power generation efficiency have been improved. However, it can only be designed for a single specific field and cannot be universally applied to multiple fields such as new energy vehicles, rail transit, and industrial rotating equipment. The structure is fixed and rigid, and there is no modular assembly adaptability. It still cannot achieve a passive and wireless rotor design. The waterproof protection is only a simple treatment and does not meet the outdoor all-weather protection standard. The installation method is simple and the modification cost is high. It cannot be adapted to rotating carriers of multiple specifications and structures. Its versatility and practicality are seriously lacking. It also does not solve the common industry problems of stator-rotor spacing misalignment and easy collision and wear under bumpy road conditions.

[0006] Furthermore, regenerative braking energy recovery systems used in the industry, such as those employed by Tesla, only operate when the vehicle is decelerating. They are essentially unable to generate electricity during constant speed, normal driving, coasting, and idling. Moreover, the recovered energy originates from a small coil area inside the drive motor, resulting in limited power generation area and capacity. The recovery capacity decreases significantly under conditions such as low temperature and full charge, making it impossible to achieve continuous energy harvesting under all operating conditions. This is fundamentally different from the technology of this invention.

[0007] In summary, existing first to fourth generation technologies and Tesla's regenerative braking system cannot simultaneously meet the requirements of multi-field universality, passive wireless safety, fully sealed waterproofing, modular installation, continuous power generation under all working conditions, and large-span size adaptation. Furthermore, they lack an adaptive anti-collision and stabilization structure specifically designed for vehicle bumps and road undulations. Therefore, there is an urgent need for a suspended magnetic self-generating device that is frictionless, wear-free, modularly assembled, multi-form installation, universally applicable, and possesses complete sealing protection, bump-adaptive gap stabilization, and shock-proof and anti-loosening limiting capabilities. This device should meet the diverse outdoor harsh working conditions requirements of civilian vehicles, new energy vehicles, buses, trucks, heavy trucks, rail transit, household and industrial rotating equipment. Summary of the Invention

[0008] Addressing the fundamental shortcomings of existing first to fourth generation technologies and Tesla regenerative braking systems, such as susceptibility to impacts and scratches under bumpy conditions, lack of weather resistance, and absence of anti-loosening limits, this invention provides a levitation magnetic self-generating multi-purpose wheel flange power generation device. As a revolutionary fifth-generation kinetic energy recovery power generation technology, it employs the principle of levitation magnetic force for non-contact, air-based cutting power generation, abandoning the traditional mechanical friction transmission structure. Through multi-form modular permanent magnet rotor deployment, multiple stable installation methods, and adjustable width and thickness designs, it can be adapted to bicycles, two-wheeled electric vehicles, electric vehicles, motorcycles, automobiles, buses, and trucks. It is suitable for all categories of applications, including heavy trucks, rail transportation, household motors, and industrial rotating equipment. The rotating side is passive, wireless, and wire-free, while the fixed side features centralized wiring and substation. It is also equipped with an integrated waterproof and sealing structure, corrosion-resistant and insulating protective structure, a bump-adaptive gap-stabilizing structure, a shock-absorbing and buffering structure, and an anti-loosening limit structure. It can achieve automatic power generation, surplus kinetic energy recovery, and voltage-stabilized energy storage and utilization throughout the entire driving and rotation process. It is suitable for complex working conditions such as open-air rain, snow, mud, high and low temperatures, and severe sun exposure. It has a wide range of applications, a reliable structure, no mechanical wear, flexible installation, and extremely strong safety and compatibility, completely making up for all existing technical shortcomings.

[0009] A multi-purpose rim-mounted self-generating power generation device with suspended magnets includes: a permanent magnet rotor assembly, a fixed stator assembly, a gap adjustment support, and a power control and energy storage module. The permanent magnet rotor assembly is installed in a modular configuration at the outer edge of a rotating carrier, which includes, but is not limited to: the outer edge of a bicycle, two-wheeled electric vehicle, electric tricycle, new energy electric vehicle, passenger car, SUV, bus, truck, heavy truck, train, high-speed train, rail transit wheel, the outer edge of a household motor, the outer edge of an industrial motor's rotating end, and the outer edge of an industrial equipment transmission wheel. The permanent magnet rotor assembly adopts a standardized, independent, modular design, consisting of several structurally uniform and standardized components. It is composed of uniform permanent magnet single-unit modules; the deployment area is limited to the circumferential empty space on the outer edge of the rotating body, without interfering with the original rotating structure or affecting the safe operation of the original vehicle or equipment; the permanent magnet rotor assembly has four modular deployment forms that can be selected individually or combined with each other: the first type: outer straight plate type deployment: adopts flat plate-shaped single-unit modules, imitating the thin plate shape of brake pads, and is distributed in a straight line at equal intervals along the outer edge of the rotating body; it can be deployed in a small number of single groups, multiple groups at intervals, or continuous deployment around the whole circle as needed, with a simple outline, low wind resistance, and convenient assembly and disassembly, and is suitable for various civilian vehicles, new energy electric vehicles, and light industrial rotating wheels. The second type: Inner ring-shaped layout: Utilizing inwardly curved single-unit modules, these modules conform to the inner arc of the rotating body, with multiple curved modules joined together to form a closed-loop magnetic array. This concealed layout does not expose the components and does not affect the appearance or existing equipment structure. It features a large magnetic cutting area and high power generation efficiency, making it suitable for buses, trucks, heavy trucks, trains, high-speed trains, and large industrial rotating equipment. The third type: Brake pad type card-style independent single-unit layout: Employing independent flat square card-style magnetic modules, designed with reference to the independent single-unit structure of brake pads. It allows for flexible installation at single points, two points symmetrically, or multiple points dispersedly. No need for a complete ring layout; individual pads can be replaced independently. Suitable for various small cars, electric vehicles, and small industrial motor equipment with limited space and requiring simple retrofitting. The fourth type: segmented modular assembly: adopts standard segmented permanent magnet modules, which can be freely combined into various modes such as small segment single assembly, half circle assembly, and full circle encirclement; it is compatible with rotating wheels of different diameters and specifications, and can be used in civil vehicles, new energy vehicles, buses, freight cars, rail transit, household motor fields, and industrial rotating equipment of all sizes, with strong mass production adaptability.

[0010] This invention further optimizes structural diversity, simultaneously accommodating both arc-shaped circumferential layout and planar end-face facing layout: the permanent magnet rotor unit can be designed as square, rectangular, circular, elliptical, and any adaptable irregular structure, and is matched with the stator end face using a planar block end-face facing coupling design; after assembly, the rotor plane and the stator plane are parallel and spaced apart, forming a planar-to-planar magnetic induction cutting power generation pair, which has uniform force, stable magnetic gap, strong shock resistance, and convenient installation and adjustment.

[0011] Meanwhile, the arrangement and overall size of the stator and rotor of this invention can be freely adapted to different vehicle models and installation spaces: it can be designed as a narrow, thin, and small-sized modular structure for bicycles, two-wheeled electric vehicles, and light electric vehicles with narrow installation spaces, allowing for concealed installation without damaging the appearance; it can also be designed as a wide, thick, and large-sized gradient module for buses, trucks, heavy trucks, rail transit, and heavy-duty industrial equipment with large wheels, thick-walled structures, and large installation gaps, achieving full-size adaptation from small two-wheeled vehicles to large transportation and heavy-duty industrial carriers.

[0012] The stator and rotor modules can be freely arranged in various ways: full-row layout, continuous layout with all coils, segmented interval layout, and separate independent layout. The full-row structure has high power generation density and high power; the continuous layout with all coils has strong power generation continuity and stable output; the segmented and separate layouts are flexible to install, convenient to replace parts, and have low maintenance costs. The most reasonable layout can be freely selected according to different vehicle models, power requirements, and installation positions.

[0013] The above four modular deployment forms are uniformly matched with a variety of stable installation structures: using special fixed brackets, ring clamps, fixed-point buckles, bolt locking, and selective local drilling reinforcement as needed; flexible selection and matching according to different vehicle models, new energy vehicle models, buses, freight cars, rail transit, household motors, and industrial equipment structures to ensure firm installation, no loosening or shaking during operation, and excellent dynamic balance performance.

[0014] Adding a bump-adaptive anti-collision stabilization structure: This invention addresses industry pain points such as stator-rotor spacing misalignment, magnetic gap disorder, mutual collision and scraping, abnormal noise and wear caused by uneven road surfaces, potholes and bumps, and wheel bounce when vehicles are driving. The fixed stator assembly is equipped with an elastic floating adaptive suspension support; the stator mounting support does not adopt a purely rigid fixed method. An elastic buffer and shock absorption component and a vertical guide limit structure are set between the support and the stationary base, allowing the stator to synchronously and slightly adaptively float and displace with the wheel bounce; at the same time, relying on the inherent magnetic attraction between the stator and rotor to form a magnetic self-centering and automatic centering and leveling effect, it always maintains a uniform and constant floating magnetic gap, which can not only meet the normal bounce stroke of the vehicle, but also completely avoid stator-rotor contact collision, one-sided wear, and abnormal noise failure under bumpy conditions.

[0015] The stator assembly and the rotor module are equipped with a high-elasticity, weather-resistant, shock-absorbing pad on the contact surface between the stator assembly and the clearance adjustment support, and the contact surface between the rotor module and the mounting base. This effectively absorbs driving vibrations, weakens the transmission of hard vibrations, and avoids frequent fluctuations in the magnetic gap. Each permanent magnet modular unit is equipped with a limiting edge and an anti-loosening buckle structure on its outer side. The bolt assembly adopts a multi-locking structure of flat washers, spring washers, and anti-loosening nuts, which can effectively resist the centrifugal force of high-speed vehicle driving and long-term bumps and vibrations, prevent the modules from shifting, loosening, or falling off, and greatly improve the overall stability and service life of the machine.

[0016] The invention features a high and low temperature all-weather adaptability design: the permanent magnet module, coil insulation material, epoxy resin potting material, and buffer sealing components are all made of special materials that are resistant to high and low temperatures, anti-aging, and anti-demagnetization. It can adapt to various extreme climate environments such as high temperature exposure in summer, severe cold in winter, ice and snow in the north, plum rain and humidity in the south, and dusty and muddy mountainous areas. It will not fade, crack, age, or demagnetize over a long period of time, and its insulation and magnetic properties will remain stable.

[0017] Self-closed-loop passive working design: This device adopts a self-generating and self-closed-loop working mode. It does not require an external auxiliary power supply or additional power supply lines. It generates electricity entirely by relying on the magnetic induction of the wheel rotation. It is simple to install, has low modification costs, and is applicable to a wider range of scenarios.

[0018] The permanent magnet rotor assembly is a completely passive and circuitless structure: all permanent magnet modules are equipped with only permanent magnet steel bodies, without built-in coils, circuit boards, external leads, or any electrical components; it rotates passively and synchronously with the rotating body throughout the entire process, eliminating safety hazards such as rotation entanglement, wire grinding, wire breakage, and short circuits from the source, which is different from the inherent defects of the third and fourth generation rotors with live wiring.

[0019] The fixed stator assembly is fixed to the stationary base next to the rotating body by a gap adjustment support, including the vehicle wheel arch, suspension, chassis, rail transit fixed frame, and industrial equipment fixed base; a uniform and safe magnetic gap is maintained between the fixed stator assembly and the permanent magnet rotor assembly, with no physical contact, friction, or mechanical wear throughout the process; the fixed stator assembly is internally sealed with an induction coil and a protective shell, which is the only wiring and the only power output terminal of the entire device.

[0020] The gap adjustment support has the function of fine adjustment of the front and rear and vertical gaps, which can adapt to different working conditions and different vibration amplitudes, avoid bumpy operation and collision noise, ensure continuous and stable power generation without air, and make up for the shortcomings of existing third and fourth generation technologies that have no gap adjustment and are easily damaged by collision.

[0021] The power control energy storage module is electrically connected to the fixed stator assembly and integrates a rectifier unit, a voltage regulator unit, a voltage regulation unit, an anti-backflow unit, and an intelligent energy recovery and control unit. It converts the alternating induced current generated by magnetic cutting into stable direct current, which can be connected to vehicle batteries, power batteries, new energy vehicle energy storage systems, bus / freight / heavy truck on-board power supplies, rail transit energy storage power supplies, and industrial equipment backup energy storage power supplies as needed, realizing the recovery, storage, and secondary utilization of surplus rotational kinetic energy.

[0022] The power generation structure of this invention can be independently deployed on all four wheels, enabling all four wheels to generate electricity simultaneously and continuously under all working conditions. Energy collection is uninterrupted regardless of whether the vehicle is moving at a constant speed, coasting, going downhill, or accelerating, significantly improving the energy utilization rate of the entire vehicle.

[0023] Integrated waterproof and sealed protective structure design: The fixed stator assembly is equipped with a fully enclosed waterproof and sealed protective shell. The induction coil inside the fixed stator assembly is integrally vacuum potted and cured with epoxy resin to achieve full insulation, waterproof, moisture-proof, shockproof, and leakage prevention. The cable lead-out position of the fixed stator assembly is equipped with a waterproof and sealed gland connector to prevent water seepage, dust, and mud from entering through the cable gaps. The end face of the fixed stator assembly facing the permanent magnet rotor is equipped with an annular waterproof baffle structure to guide rainwater and mud outward and prevent water stains from seeping into the shell along the gaps.

[0024] The outer surface of each permanent magnet unit module of the permanent magnet rotor assembly is provided with an anti-corrosion and anti-rust protective coating, and the permanent magnet module as a whole adopts a hard insulating encapsulation structure, with only the magnetic force action surface exposed. The rotor as a whole has no circuit, no wiring, and no conductive components. Even if it is exposed to rain, mud and water splashes, sludge adhesion, and high and low temperature exposure for a long time, it will not produce short circuits, leakage, corrosion and demagnetization.

[0025] This device features a multi-layered sealing, corrosion-resistant, insulating, and anti-fouling structure design, achieving an overall IP67 outdoor all-weather protection rating. It can be used for long-term outdoor operation of bicycles, electric vehicles, locomotives, cars, buses, trucks, heavy trucks, rail transit, household motors, and industrial equipment, and is resistant to rain, mud contamination, dust accumulation, and high-pressure water washing. At the same time, a uniform levitation magnetic gap is reserved between the rotor and stator, so a small amount of floating dust or thin layer of sludge will not interrupt the magnetic lines of force and will not affect the normal air-to-ground power generation efficiency. It is safe, stable, maintenance-free, and has a long service life.

[0026] The core advantages of the fifth-generation technology of this invention compared with the existing first to fourth generation technologies are as follows: 1. Compared with the first-generation friction technology: it achieves complete contactlessness, zero friction, zero wear, and no additional resistance. It can work normally in rainy weather and sludge conditions, without slippage or wear failure. 2. Compared with the second-generation built-in technology: it does not require modification of the main unit structure, can be easily installed and removed externally, and is compatible with multiple fields and carriers of various specifications, greatly expanding its application range. 3. Compared with the third-generation simple external technology: it achieves a completely passive and wireless rotor, completely eliminating the safety hazards of leakage, wire breakage, and entanglement. It adds four modular deployment forms and a planar end-face coupling structure, and has IP67 rating. The structure is all-weather waterproof, dustproof and corrosion resistant, with added shock-adaptive gap stabilization, shock absorption and anti-loosening limit structure, making it suitable for new energy, rail and industrial fields; 4. Compared with the fourth generation of single-field maglev technology: it breaks the field limitation and achieves universality in all fields. The multiple installation methods are suitable for various carriers. The passive wireless design of the rotor is safer. The sealing protection level is higher. It has added high and low temperature resistance and all-weather adaptability. The modification and mass production costs are lower.

[0027] Compared to Tesla's regenerative braking energy recovery system: Tesla's system can only recover energy during deceleration, has a small energy harvesting area, and limited power generation capacity; it generates virtually no power during constant speed, coasting, and normal driving; and it relies on the drive motor, so it cannot be independently deployed on all four wheels, making expansion impossible. This invention is an independent external magnetic suspension power generation system, where all four wheels can be independently deployed to generate power simultaneously. As long as the wheels rotate, regardless of constant speed, coasting, downhill, or acceleration, it can continuously and stably generate power throughout the entire process; the magnetic induction area is larger, the energy harvesting capacity is stronger, and it is not limited by temperature or battery status; it can be subsequently matched with mature power management, voltage regulation, energy storage, and discharge modules, making system integration simple and highly feasible.

[0028] Special Protection Note: Any minor adjustments, simple modifications, equivalent replacements, local improvements, or combination transformations made to the shape, size, thickness, curvature, arrangement density, fixing method, stator shape, and magnetic gap distance of the permanent magnet module based on the core structure, core principle, and core layout logic of this invention; regardless of whether this device is applied to bicycles, electric vehicles, locomotives, passenger cars, new energy vehicles, buses, freight trucks, heavy trucks, rail transit, household motors, industrial motors, or other rotating machinery, all simple modifications based on the equivalent principles and equivalent structures of this invention fall within the protection scope of this application.

[0029] When any vehicle capable of rotational motion (bicycle, electric vehicle, locomotive, ordinary vehicle, new energy electric vehicle, bus, freight truck, heavy truck, high-speed train, household appliance, industrial motor equipment) is in operation, it drives the outer permanent magnet rotor assembly to rotate synchronously in a circular motion. This invention adopts the principle of rotor-stator split passive power generation. The permanent magnet rotor assembly is composed only of permanent magnet steel units and is a completely passive structure. No induction coils, circuit boards, external leads, or electrical components are set inside. It only serves as a constant magnetic field provider and rotates synchronously with the rotating body. All induction power generation coils, circuit wiring, and power output are all concentrated on one side of the fixed stator assembly, forming a separate layout where the rotating side is de-energized and the stationary side is energized. This avoids the hidden dangers of rotational winding, wire wear, wire breakage, short circuit leakage, etc. from the structural source.

[0030] The permanent magnets continuously and uniformly sweep across the stationary fixed stator assembly, relying on the electromagnetic induction principle of suspended magnetic lines of force to continuously cut the stator induction coils and generate alternating induced electrical energy. After rectification, voltage stabilization, anti-backflow, and intelligent regulation by the power supply control energy storage module, the electrical energy is stably stored in the corresponding energy storage unit. It provides micro-power replenishment during normal uniform operation, moderate power generation during coasting and no-load operation, and enhanced power recovery during downhill / deceleration / high-load rotation stages. The entire process is non-contact levitation power generation, with no friction loss and no additional operating resistance. Combined with the stator's fully sealed waterproofing, rotor corrosion-resistant insulation protection, shock-adaptive floating gap stabilization, shock absorption, anti-loosening limit, and high and low temperature weather-resistant structure, it can work stably for a long time in complex environments such as outdoor rain, mud, dust, and extreme cold and sun exposure, without leakage, moisture, corrosion failure, or abnormal noise from bumps and collisions.
