Description

Technical Field

[0001] This invention relates to the field of automotive kinetic energy recovery and power generation, and more particularly to a wheel magnetic induction power generation device under all operating conditions. Background Technology

[0002] During the rapid development of the new energy vehicle industry, limited driving range, high charging frequency, and high operating costs are key issues restricting the user experience and widespread adoption of vehicles. During vehicle operation, the continuous rotation of the wheels generates a large amount of idle kinetic energy, which is not effectively recovered and utilized, resulting in energy waste.

[0003] Existing vehicle energy recovery structures are mostly braking energy recovery, which can only achieve energy recovery briefly when the vehicle is decelerating or braking. They cannot recover energy during constant speed driving or acceleration. The energy recovery conditions are limited, the overall utilization rate is low, and they cannot continuously replenish the vehicle's electrical energy, making it difficult to fundamentally improve the vehicle's short range.

[0004] In view of the shortcomings of existing technologies, there is an urgent need to design a wheel magnetic induction power generation device that can adapt to all driving conditions of vehicles, continuously and stably recover the kinetic energy of wheel rotation, has good protection and strong versatility. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a wheel magnetic induction all-condition power generation device in view of the current situation of the prior art, which solves the technical problems of single kinetic energy recovery conditions, low recovery efficiency and inability to continuously replenish power in the existing technology, so as to realize continuous kinetic energy recovery and power generation in the entire driving state of the vehicle, improve the vehicle's range and reduce vehicle energy consumption.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a wheel magnetic induction full-condition power generation device, including a stator assembly, a rotor assembly, a protection assembly, and a voltage stabilizing and rectifying power supply assembly; The stator assembly includes a coil assembly and a fixed bracket. The coil assembly is integrally insulated and encapsulated, and can be an integrated structure or a split structure. The coil assembly is installed on the side of the wheel and fixed at a suitable position through the fixed bracket, with a safety clearance reserved between it and all rotating parts of the wheel. The stator assembly as a whole remains relatively stationary with respect to the vehicle body. The rotor assembly includes a permanent magnet and an insulating protective layer, and can adopt an integrated structure or a split structure. The permanent magnet is fixedly assembled to the power generation area of ​​the coil assembly. An insulating protective layer is set at the contact position between the permanent magnet and the hub. An electromagnetic cutting safety gap is reserved between the permanent magnet and the coil assembly. The protective assembly includes two sets of protective layers, which are installed on both sides of the wheel hub. The voltage stabilizing and rectifying power supply component includes a voltage stabilizing and rectifying device and a power transmission line. The electrical energy output by the coil component can be output individually or in series or parallel combination. The voltage stabilizing and rectifying device is fixedly installed at any suitable position on the vehicle body. The coil component is electrically connected to the voltage stabilizing and rectifying device through the power transmission line. The output end of the voltage stabilizing and rectifying device is used to connect to the vehicle battery.

[0007] Furthermore, the coil assembly is integrally sealed and molded using insulating potting material, providing waterproof, dustproof, and insulating protection.

[0008] Furthermore, the permanent magnet is made of high magnetic energy permanent magnet material and is evenly distributed along the wheel hub.

[0009] Furthermore, the insulating protective layer is a high-temperature resistant insulating buffer structure, which realizes electrical isolation and shock absorption protection between the permanent magnet and the wheel hub.

[0010] Furthermore, the voltage regulator and rectifier integrates rectification, voltage regulation, and filtering functions, and can convert alternating induced current into stable direct current.

[0011] Compared with the prior art, the advantages of the present invention are as follows: 1. This invention abandons the traditional single braking energy recovery mode and can continuously recover the rotational kinetic energy of the wheels in all driving conditions such as vehicle acceleration, constant speed, deceleration, and coasting. The energy recovery time and utilization rate are greatly improved, effectively extending the driving range of new energy vehicles and reducing the frequency of vehicle charging and daily vehicle energy consumption costs.

[0012] 2. The coil assembly adopts an overall insulation and potting structure, which has good overall sealing performance and can be adapted to complex driving environments such as rainy days, muddy and dusty conditions. It is not easily affected by moisture, dust accumulation, or short circuits, and the device has a long service life and high working stability.

[0013] 3. Multiple protective structures are set up. The insulating protective layer achieves electrical isolation and shock absorption, and the protective layers on both sides can prevent the adsorption and accumulation of debris, avoid the degradation of power generation efficiency and structural jamming failure, and provide comprehensive protection performance.

[0014] 4. This device has strong versatility in installation location and can be adapted to the modification and pre-installation of various passenger cars and new energy vehicles. It has a compact structure, does not occupy extra space in the vehicle, and has extremely strong adaptability.

[0015] 5. Equipped with an integrated voltage regulator and rectifier structure, the output power is stable and smooth, and will not cause current surges to the vehicle battery, ensuring high charging safety and reliability. Attached Figure Description

[0018] like Figures 1 to 4 As shown, the present invention includes a stator assembly, a rotor assembly, a protection assembly, and a voltage regulator and rectifier power supply assembly.

[0019] The stator assembly consists of a coil assembly 2 and a fixed bracket 1. The coil assembly 2 is provided with an insulating potting layer 11 to form an integrated waterproof and insulating structure. The coil assembly 2 is fixedly installed on the side of the wheel at the matching position through the fixed bracket 1, with a safety gap reserved between it and the rotating parts of the wheel, so that it remains relatively stationary with the vehicle body during driving.

[0020] The rotor assembly consists of permanent magnets 4 and insulating protective layer 5. Multiple sets of high magnetic energy permanent magnets 4 are evenly distributed and installed in the hub 6 at the position corresponding to the coil assembly 2. The permanent magnets 4 and the hub 6 are fully covered by the insulating protective layer 5 to achieve electrical isolation and shock absorption. An electromagnetic cutting gap is reserved between the permanent magnets 4 and the coil assembly 2 to ensure the efficiency of magnetic wire cutting power generation.

[0021] Protective layers 7 are installed on both sides of the hub 6. The protective layers 7 can prevent road debris from adhering to the surface of the device, while maintaining ventilation and heat dissipation to avoid heat accumulation affecting the performance of the device.

[0022] The output end of the coil assembly 2 is connected to the power transmission line 8, and the power transmission line 8 is connected to the voltage stabilizing and rectifying device 9 fixed at the vehicle body adaptation position. The voltage stabilizing and rectifying device 9 integrates rectification, voltage stabilization and filtering modules to convert the alternating induced current generated by the coil assembly 2 into stable DC power, which is finally connected to the vehicle battery 10 to achieve continuous power replenishment.

[0023] When the vehicle is in motion, the wheel hub 6 drives the permanent magnet 4 to rotate continuously, and the relatively stationary coil assembly 2 continuously generates induced electrical energy, realizing uninterrupted kinetic energy recovery and power generation under all operating conditions. This device has a simple structure, strong protection, and wide compatibility with various vehicle models, and has good application and promotion prospects.

[0024] like Figures 1 to 4As shown, during vehicle operation, the wheel hub continuously rotates, and the permanent magnet rotates synchronously with the hub, forming a continuous relative motion with a coil assembly fixed to the side of the wheel and remaining stationary. The permanent magnet continuously cuts the magnetic field lines of the coil assembly, generating an alternating induced current based on the principle of electromagnetic induction. The induced current is transmitted to a voltage regulator and rectifier through a transmission line, and after rectification, voltage regulation, and filtering, it is converted into a stable direct current to continuously replenish the vehicle's battery.

[0025] Meanwhile, the insulation potting structure of the coil assembly can achieve waterproof and insulation protection; the insulation protection layer between the permanent magnet and the wheel hub can prevent electrical conduction and buffer driving vibration; the protective layers on both sides of the wheel can block the adsorption of debris, avoid affecting the power generation efficiency and structural operation stability, and comprehensively ensure the stable operation of the device under all working conditions.
