Abstract
Description
Technical Field
[0001] The present invention relates to the technical fields of on-vehicle kinetic energy recovery and vehicle wheel hub self-power generation energy-saving equipment, and particularly relates to an on-vehicle wheel hub external rim self-power generation equipment assembly. Background Art
[0002] Existing on-vehicle power generation equipment mostly relies on engine belts to drive power generation and on-vehicle independent generator sets, with high energy consumption, bloated structures, and large space occupation; existing wheel hub power generation solutions mostly adopt power taking and transmission from the outer edge of the steel basin, with a large force arm span, large centrifugal shaking during high-speed driving, severe body jitter, prominent safety hazards, and unreasonable transmission ratios. When the large circle of the wheel rotates, the operating stroke of the power generation component is insufficient, resulting in low power generation efficiency.
[0003] The inventor has previously filed a number of related prior application patents, forming a mature technical system related to magnetic circuit power generation; in the existing technical system, there is a lack of a complete set of power generation assembly equipment that can rely on the inventor's previous proprietary patent technology foundation, adopt inner-axle speed increase transmission, three-layer rotor integrated环抱 structure, flat integrated assembly, be universal for multiple vehicle models, be expandable and upgraded on the basis of the original technical system, and can also be independently implemented; there is no exclusive supporting assembly that is optimized in multiple dimensions such as transmission logic, internal hierarchical structure, overall integrated protection, and dual-mode installation. To fill the existing technical gap and overcome various defects of traditional structures, the technical solution of the present invention is specifically proposed. Summary of the Invention
[0004] The purpose of the present invention is to provide an on-vehicle wheel hub external rim self-power generation equipment assembly, to solve the industry pain points of large shaking during transmission of the traditional steel basin outer rim, low power generation efficiency, poor adaptability, low integration, and the lack of a supporting integrated upgrade assembly in the inventor's previous proprietary patent system; to achieve optimized transmission mode, efficient power generation with multi-layer magnetic fields, integrated protection and heat dissipation, universality for light and heavy vehicle models, and at the same time, the solution is independent and can be synergistically expanded on the basis of the inventor's prior proprietary patents, broadening the patent protection boundary.
[0005] To achieve the above purpose, the present invention adopts the following technical solutions: The present invention includes a power generation assembly main structure, an inner-axle drive connection mechanism, a double-layer or three-layer rotor combination component that can be realized, a centrally fixed stator, an external protection housing, and an installation adaptation component. The entire assembly adopts a flat disc overall shape and is integrally installed in a preset assembly area outside the vehicle wheel hub, the outer shaft of the vehicle wheel track wheel, and the outer edge of the steel basin. It has a compact appearance, small space occupation, and good vehicle installation adaptability.
[0006] The name "rim" is the exclusive technical name of this application; the physical installation location specifically refers to the positions of the wheel, wheel hub, outer shaft of the vehicle wheel, and the outer edge of the steel basin, clearly distinguishing: "rim" is the exclusive technical name of this patent, and "outer edge" is the physical installation location outside the edge of the steel basin. The semantics and definition boundaries of the two are clearly distinguished.
[0007] By adopting the principle of power transmission structure, the traditional long lever arm transmission mode of the outer edge of the steel ring is abandoned and replaced with short-distance power take-off on the inner side of the hub center shaft, which greatly shortens the force arm and reduces the centrifugal force and body sway generated by high-speed rotation from the source, thus significantly improving the running stability.
[0008] This solution adopts the principle of shaft-driven small belt with large speed increase transmission. Relying on the small power output of the shaft, it drives the three-layer rotor assembly to rotate. At the same travel speed, the number of rotor rotations far exceeds that of the outer transmission structure of the steel basin, effectively increasing the frequency of magnetic cutting and improving the overall power output.
[0009] The internal structure features a three-layer integrated rotor assembly, with multiple rotors surrounding and fixing the stator in the center, forming a comprehensive multi-layer encircling magnetic field cutting system. This results in a large power generation area and high energy conversion efficiency. An adjustable gap assembly structure is set between the rotor and the stator, allowing for precise control of the magnetic gap distance during installation and commissioning. This prevents friction and collision between moving and stationary parts while maintaining optimal magnetic induction working conditions.
[0010] The external semi-enclosed flat protective shell provides integrated protection against dust, sand, and impact for the internal magnetic circuit and rotor / stator structure. The shell is equipped with ventilation tunnels around its perimeter, which rely on the airflow from the vehicle to form natural ventilation and heat dissipation. There is no need to add additional heat dissipation power components, and the temperature can be stabilized independently, ensuring the magnetic stability of the magnet and the long-term reliable operation of the coil.
[0011] The installation structure features a dual-adaptation mode: heavy-duty vehicles and heavy-load models can have load-bearing bearings installed at the wheel axle and hub connection points to share the weight of the assembly and reduce rotational friction loss; light-duty vehicles such as electric two-wheelers and three-wheelers can omit the bearings and use multiple rigid support columns for circumferential rigid fixation, simplifying the structure, reducing weight, and compressing production costs, adapting to various vehicles with external wheel hubs and steel basin outer edge structures.
[0012] This power generation assembly is positioned as an upgraded and complementary assembly based on the inventor's prior patented technologies. It can be used in combination with the inventor's prior magnetic circuit basic structure to improve the overall technology industry chain. At the same time, the transmission architecture, internal hierarchical structure, assembly integration form and installation adaptation system of this invention are completely independent. The technical solution does not overlap or conflict with the inventor's prior patents. It can be used as a set or produced and launched on the market separately. It is flexible in use and has a low threshold for industrialization. Beneficial effects
[0013] Transmission advantages: Adopting the principle of mechanical transmission, the short lever arm inside the shaft takes force, eliminating the defects of large centrifugal force and strong vibration caused by the outer edge drive of the steel basin, ensuring safe and stable high-speed operation; small belt with large speed-increasing transmission, increasing the rotor speed at the same vehicle speed, and the power generation efficiency is significantly better than the traditional outer edge drive scheme.
[0014] Structural advantages: The double-layer or triple-layer integrated rotor surrounds the central stator, with multiple magnetic fields cutting from multiple sides, resulting in a wide power generation working surface and high conversion efficiency; the magnetic gap is adjustable, making assembly and debugging convenient and with a high fault tolerance rate.
[0015] Protective and heat dissipation advantages: The semi-enclosed shell provides integrated protection, resisting impacts and preventing the intrusion of foreign objects; the wind tunnel provides self-heating, ensuring stable operating temperature and extending the service life of the entire machine.
[0016] Universal compatibility advantages: Dual-mode installation of bearings and support columns, adaptable to various installation locations such as wheel hubs, outer axles, and the outer side of steel basins, covering both light and heavy vehicle models; not limited to specific vehicle models, compatible with various external wheel hubs and rail locomotives, with a wide range of application scenarios.
[0017] Advantages of patent layout: It relies on the inventor's own prior patent technology system for iterative upgrades, which has both technology inheritance and independent innovation; the boundary between new and old technologies is clearly defined, avoiding the risk of repeated examination and rejection, forming a complete patent protection barrier with tight protection.
[0018] Industrialization advantages: The overall shape is flat and compact, making it aesthetically pleasing and space-saving when installed on a vehicle; the structure is simple and easy to mass-produce, and it can be pre-installed at the factory or modified later, making it highly commercially viable. Detailed Implementation
[0019] The present invention will now be described in further detail with reference to the accompanying drawings.
[0020] An externally mounted vehicle wheel hub self-generating power generation device assembly includes: 1 - a power generation assembly housing, 2 - a three-layer rotor assembly, 3 - a centrally fixed stator, 4 - a shaft drive connecting seat, 5 - a ventilation and heat dissipation tunnel, 6 - a support bearing assembly position, 7 - a rigid support column mounting position, 8 - an outer body of the wheel hub, 9 - a wheel hub central shaft, and 10 - the outer edge of the steel rim.
[0021] The entire flat power generation assembly is installed on the outer side of the wheel hub, in the pre-set assembly area of the hub and the outer edge of the steel basin, and the outer edge can extend to the large half-ring area of the steel rim; the power is input through the central shaft of the wheel hub via the shaft transmission connector, driving the three-layer rotor assembly to rotate the relatively centrally fixed stator, completing the multi-layer magnetic induction cutting power generation operation.
[0022] In actual assembly, heavy-duty vehicles are equipped with support bearings at the wheel axle and hub connection points to achieve load-bearing capacity and reduce wear; light-duty vehicles eliminate bearings and use multiple rigid support columns for circumferential fixation; the magnetic gap is finely adjusted through the housing adjustment structure, and natural heat dissipation is achieved through a wind tunnel during driving. Assembly structures and connection methods not described in detail in this invention are all existing mature technologies in the field and will not be elaborated upon.
[0023] Compared to existing publicly available technologies and the inventor's own prior patent technology system, this application has clear distinctions and substantial innovations, and is not a simple structural superposition or conventional modification: First, this application changes the core position and transmission logic of power take-off, circumventing the conventional method of force transmission along the outer edge of the wheel hub steel basin used in the industry and the inventor's prior art. It is the first to adopt the short-arm internal drive power take-off between the outer axle of the wheel and the inner axis of the hub, which solves the inherent defects of vibration, large centrifugal load and poor safety from the root of mechanical structure. This is a substantial improvement in the transmission mechanism.
[0024] Second, this application features a unique three-layer integrated rotor surrounding a centrally located stator with a multi-layer encircling magnetic circuit assembly, which differs from conventional single-layer power generation structures and the inventor's previous basic magnetic circuit arrangement. This achieves multi-faceted superimposed magnetic induction cutting, significantly improving power generation capacity and working efficiency, rather than being a simple equivalent replacement of existing structures.
[0025] Third, this application precisely defines the concept of the exclusive technical name of the vehicle edge and the physical installation location of the steel basin vehicle edge, and clearly defines the exclusive installation area of the structure on the outer side of the wheel, hub, wheel axle, and steel basin; at the same time, it integrates multiple functions such as speed-up internal drive, adjustable magnetic gap, shell protection, self-heating during travel, and dual-mode adaptation for light and heavy vehicles, forming an independent and complete flat set of equipment assembly; the whole is an iterative upgrade based on the inventor's prior patents, which can be networked together to form a complete technical system, or can be implemented independently without the previous basic structure. The overall technical concept, structural combination, and application form are different from all existing disclosed solutions.
[0026] Fourth, the overall technical solution of this application is not a simple superposition of conventional designs and conventional means in the field. It is an overall original optimization made by the inventor based on his own previous patent technology accumulation, combined with mechanical transmission, magnetic circuit layout, vehicle adaptation and working condition protection. It has clear novelty, substantial inventiveness and industrial practical value, there is no prior art teaching, it does not meet the rejection conditions, and it meets the statutory conditions for independent patent authorization.
