[0002] The power system of electric vehicles is mainly powered by batteries, but the energy of batteries is limited and needs to be charged frequently, especially when driving long distances. This not only wastes more time, but also increases the cost of charging. Currently, when electric wheels brake or decelerate, the kinetic energy of the wheels is converted into electrical energy and stored in the battery. However, this method is greatly affected by the braking distance and the speed of the electric vehicle, which makes the recovered energy limited, resulting in the actual endurance of the electric vehicle not being significantly improved. The efficiency of energy recovery is relatively low, and it is difficult to effectively improve the endurance of the electric vehicle. Summary of the invention

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] First embodiment

[0019] The kinetic energy recovery of electric wheels is to convert the kinetic energy of the wheels into electrical energy and store it back in the battery. When the electric wheels brake or decelerate, they will convert the kinetic energy of the wheels into electrical energy and store it in the battery, thereby reducing energy waste and achieving multiple goals such as improving battery life, saving energy, reducing brake system wear, and improving energy efficiency. Since this method is greatly affected by the braking distance and the speed of the electric vehicle, the recovered energy is limited. In order to improve the energy recovery efficiency and reduce the dependence of electric vehicles on external charging, refer to Figure 1 - Figure 3 The present embodiment provides an electric vehicle wheel-driven intelligent electronic battery device, including an electric vehicle wheel housing 5, wherein a hollow axle 8 installed on the electric vehicle transmission shaft is arranged at the axis center of the electric vehicle wheel housing 5. The hollow axle 8 with a reasonable structural design can reduce the material usage and the total weight of the vehicle while ensuring strength and rigidity, and other key components can be accommodated inside the hollow axle 8, thereby reducing additional components and pipelines, simplifying design and wiring, and reducing the complexity of the vehicle.

[0020] The electric wheel housing 5 is removably provided with annular cover plates 13 at the axis centers on both sides thereof, and the annular cover plates 13 can seal and protect the inner side of the electric wheel housing 5. One side of the two annular cover plates 13 is respectively provided with bearings 10 fixedly embedded in the two sides of the electric wheel housing 5, and the two ends of the hollow axle 8 respectively penetrate the two bearings 10 and are rotatably connected thereto. The electric wheel housing 5 rotates more stably on the hollow axle 8, thereby improving the overall performance and safety of the electric vehicle. Bolts 9 can also be removably provided on both ends of the hollow axle 8. Installing the bolts 9 at both ends of the hollow axle 8 can strengthen the connection between the axle and other components (such as wheels, motors or other drive system components), thereby enhancing the stability of the overall structure. Especially under high load or severe operating conditions, this design helps to disperse the force applied to the axle and reduce the risk of deformation and failure. The bolts 9 can also effectively prevent axial movement or displacement at both ends of the axle, thereby ensuring the centering and operating accuracy of the drive system.

[0021] A T-ring 7 for supporting and fixing the brake disc is integrally formed on one side of the outer side of the electric wheel housing 5, and the T-ring 7 is made of aluminum alloy material to firmly mount the brake disc on the electric wheel housing 5. The T-ring 7 has an interface structure that matches the wheel hub housing. Its main function is to provide a stable mounting point so that the brake disc can be reliably connected to the drive system outside the wheel and ensure that the force transmission during the braking process does not loosen or shift. This can prevent the brake disc from loosening or being damaged due to vibration or high temperature when driving at high speed or braking frequently. It can also effectively dissipate heat during braking to prevent the performance of the brake system from being degraded due to excessive temperature.

[0022] In order to avoid the situation where the actual endurance of the electric vehicle is not significantly improved due to limited recovered energy and to reduce energy waste, an energy recovery component that utilizes the mechanical energy of wheel rotation and braking to generate current and recover electrical energy is provided on the inner side of the electric wheel housing 5. The specific implementation method is that the energy recovery component includes a plurality of permanent magnetic strips 6 distributed in a circumferential array and respectively arranged on both sides of the inner side of the electric wheel housing 5. Two adjacent permanent magnetic strips 6 are set to N and S, and two adjacent permanent magnetic strips 6 are fixed by epoxy resin glue. Epoxy resin glue, as a material with high-strength bonding properties, can provide a stable fixing effect to prevent the permanent magnetic strip 6 from shifting or loosening under high-speed operation or high-temperature environment. The precise bonding of epoxy resin glue can ensure the permanent magnetic strip 6. The consistency of position makes the magnetic field more uniform. An L-shaped hollow magnetic disk bracket 14 is fixedly installed on the outer side of the middle part of the hollow axle 8. A hollow magnetic disk 11 is detachably arranged on the outer side of the L-shaped hollow magnetic disk bracket 14. A hollow magnetic disk copper coil 15 is arranged on one side of several permanent magnetic strips 6, and the hollow magnetic disk copper coil 15 is fixedly installed on the hollow magnetic disk 11. The installation position of the hollow magnetic disk copper coil 15 can optimize the distribution of the magnetic field and improve the power generation efficiency. By directly installing the hollow magnetic disk copper coil 15 on the hollow magnetic disk 11, the relative movement of the coil and the magnetic field can be more efficient, thereby improving the energy conversion efficiency. Each hollow magnetic disk copper coil 15 has a permanent magnetic strip 6 on both sides. When the permanent magnetic strip 6 rotates, the hollow magnetic disk copper coil 15 will generate alternating current.

[0023] A rectifier 12 fixed to an L-shaped hollow disk bracket 14 is provided on one side of the interior of the hollow disk 11, and the rectifier 12 is used to convert the alternating current generated by the hollow disk copper coil 15 under the action of the magnetic lines of force of the permanent magnetic strip 6 into direct current to charge the vehicle-mounted storage battery. The rectifier 12 usually uses a diode or a transistor as a rectifying element; when the alternating current output by the hollow disk copper coil 15 passes through the rectifier 12, the diode allows the current to flow in one direction and prevents the current from flowing in the opposite direction, thereby converting the alternating current into direct current; in order to make the output direct current more stable, the rectifier 12 may also be equipped with a filter to smooth the fluctuations in the current, ensure that the direct current output is stable and suitable for battery charging, which not only improves the endurance of the vehicle, but also optimizes the energy utilization efficiency.

[0024] Second embodiment

[0025] In order to increase the load-bearing strength and stability of the entire electric wheel and ensure that the electric wheel can operate stably and safely during driving, refer to Figure 1 and Figure 3The specific implementation method is that the outer side of the electric wheel shell 5 is integrally formed with a wheel frame 4, and the outer side of the wheel frame 4 is integrally formed with a wheel rim 3. A tire 1 is installed on the outer side of the wheel rim 3, and an inner tube can also be provided on the inner side of the tire 1. The inner tube is used as a design element to enhance performance or improve driving experience in some cases. The inner tube can better maintain the air pressure of the tire 1 and prevent air leakage. The stability of the air pressure of the tire 1 directly affects the endurance and driving comfort. The wheel frame 4 is used to support and fix the tire 1 to ensure that the contact between the tire 1 and the ground is stable. The wheel rim 3 is used to ensure that the tire 1 can be firmly installed on the wheel frame 4 and ensure the airtightness of the tire 1 after inflation. The electric wheel shell 5, wheel frame 4 and wheel rim 3 are made of integrated aluminum alloy, which can increase the bearing strength and stability of the entire electric wheel, and can also simplify the structure of the electric wheel. The electric energy recovery component is arranged in the electric wheel shell 5, which can also reduce the overall weight and production cost.

[0026] During use of the present invention, the electric wheel shell 5 rotates, driving the permanent magnetic strip 6 inside it to rotate, and the hollow magnetic disk copper coil 15 is fixed on the hollow axle 8 through the hollow magnetic disk 11 and the L-shaped hollow magnetic disk bracket 14. Therefore, relative movement, namely, the magnetic field cutting effect, occurs between the permanent magnetic strip 6 and the hollow magnetic disk copper coil 15. The change in the magnetic field will generate current in the coil, and the generated alternating current will be converted into direct current through the rectifier 12 to charge the vehicle-mounted battery or for use in other electrical systems, thereby improving the cruising range of the electric vehicle.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
