Description

Technical Field

[0001] This invention belongs to the field of power generation technology, specifically relating to a permanent magnet dual-current generator. Background Technology

[0002] Currently, as the application of various rare-earth strong magnetic materials in the hub motors of new energy vehicles becomes increasingly mature, the shortcomings of new energy vehicles during operation are gradually becoming apparent. For example, new energy vehicles need to be parked and charged, and the construction of dedicated charging stations wastes a lot of resources. The inventors envisioned that if electricity could be generated during the operation of new energy vehicles, and the electricity generated by the vehicle itself could be recycled back into its driving range, it would greatly improve the range of new energy vehicles. Therefore, a generator needs to be installed on new energy vehicles. However, currently, the power generated by the rotation of the vehicle's hub is very small, and the conversion rate is low, which is insufficient to provide the ability to increase the range of new energy vehicles. After multiple designs and repeated experiments, the inventors finally invented a permanent magnet dual-current generator that generates electricity using dual currents during the rotation of the new energy vehicle's hub. The power conversion rate is high, which can help achieve long-distance range for new energy vehicles. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a permanent magnet dual-current generator, which solves the technical problems mentioned in the background art.

[0004] The objective of this invention is achieved as follows: a permanent magnet dual-current generator includes an outer rotating housing, an inner stator assembly is disposed inside the outer rotating housing, a permanent magnet block is fixedly connected to the outer rotating housing, the inner stator assembly includes a drive coil and a generator coil, and the generator coil is disposed correspondingly to the drive coil, the drive coil is electrically connected to a first power control module.

[0005] The working principle is as follows: Under the action of the first power control module, alternating current is supplied to the drive coil. After the drive coil is energized, an alternating magnetic field is generated around it. The magnetic force of the alternating magnetic field interacts with the magnetic force of the permanent magnet block, thereby driving the outer rotating shell to rotate. When the drive coil generates an alternating magnetic field, the alternating magnetic field passes through the generator coil, generating a first current in the generator coil. At this time, because the outer rotating shell is rotating with the permanent magnet, the changing magnetic field generated by the permanent magnet passes through the generator coil again, generating a second current in the generator coil. This dual-current generation is achieved through the permanent magnet, and by utilizing the superposition of the two currents, the power generation is greatly increased.

[0006] Furthermore, the outer rotating housing is cylindrical, and there are multiple permanent magnet blocks, which are evenly spaced and fixedly disposed on the inner circumference of the outer rotating housing. A lead-out end cap is rotatably connected to the left end of the outer rotating housing, and a non-lead-out end cap is fixedly connected to the right end of the outer rotating housing. The inner stator assembly includes a bracket, which is fixedly connected to the lead-out end cap. The drive coil and the generator coil are both fixedly disposed on the outer circumference of the bracket. A rotating shaft is connected inside the bracket via bearings. The rotating shaft extends to both the left and right ends of the bracket; the left end of the rotating shaft is rotatably connected to the lead-out end cap, and the right end of the rotating shaft is fixedly connected to the non-lead-out end cap.

[0007] In use, the inner stator assembly remains stationary. When the drive coil is energized with alternating current, multiple permanent magnet blocks are driven by the magnetic field to rotate the outer rotating housing. This rotation causes the non-outgoing end cap and bearing to rotate synchronously. The bearing connects to the wheel hub of the new energy vehicle, enabling vehicle movement. The outer end cap is externally fixed to the new energy vehicle via bolts or other connectors, while its interior is fixedly connected to a support frame to maintain stability, thereby ensuring the stability of the inner stator assembly. This invention's permanent magnet dual-current generator generates electricity using dual currents without affecting the normal rotation of the new energy vehicle's wheel hub.

[0008] Furthermore, the drive coil is electrically connected to a first storage battery, and the generator coil is electrically connected to a second power control module and a second storage battery. The end cap at the output terminal has multiple through holes from which the conductive wires of both the drive coil and the generator coil extend. The first storage battery provides alternating current to the drive coil under the control of the first power control module. The second power control module rectifies the current in the generator coil and stores it in the second storage battery as a backup battery.

[0009] Furthermore, the support includes a frame cylinder with a groove on its outer periphery and multiple slots inside the groove. Multiple support plates, evenly spaced along the circumference of the frame cylinder, are fixedly connected to the inner periphery of the frame cylinder. An auxiliary cylinder is fixedly connected to the inner end of each support plate. The bearing includes a first bearing and a second bearing. The first bearing is located at the left end of the auxiliary cylinder, and the second bearing is located at the right end of the auxiliary cylinder. The auxiliary cylinder is connected to the rotating shaft via the first and second bearings. The structure is simple, practical, low-cost, and highly stable.

[0010] The beneficial effects of this invention are as follows: The permanent magnet dual-current generator of this invention can generate electricity through dual currents without affecting the normal rotation of the wheel hub of a new energy vehicle. The working principle is as follows: Under the action of the first power control module, alternating current is supplied to the drive coil. After the drive coil is energized with alternating current, an alternating magnetic field is generated around it. The magnetic force of the alternating magnetic field interacts with the magnetic force of the permanent magnet block, thereby driving the outer rotating shell to rotate. When the drive coil generates an alternating magnetic field, the alternating magnetic field passes through the generator coil, generating the first current in the generator coil. At this time, because the outer rotating shell carries the permanent magnet, the changing magnetic field generated by the permanent magnet passes through the generator coil again, generating the second current in the generator coil. Dual-current power generation is achieved through the permanent magnet, and the superposition of the two currents greatly increases the power generation. Attached Figure Description

The drive coil 3 is electrically connected to a first power control module 12. The outer rotating housing 1 is cylindrical. Multiple permanent magnet blocks 2 are arranged at equal intervals and fixedly disposed on the inner wall of the outer rotating housing 1. A lead-out end cap 5 is rotatably connected to the left end of the outer rotating housing 1, and a non-lead-out end cap 6 is fixedly connected to the right end of the outer rotating housing 1. The inner stator assembly includes a bracket 7, which is fixedly connected to the lead-out end cap 5. The drive coil 3 and the generator coil 4 are both fixedly disposed on the outer wall of the bracket 7. A rotating shaft 8 is connected inside the bracket 7 via a bearing.

[0016] The working principle is as follows: Under the action of the first power control module 12, alternating current is supplied to the drive coil 3. After the drive coil 3 is energized, an alternating magnetic field is generated around it. The magnetic force of the alternating magnetic field interacts with the magnetic force of the permanent magnet block 2, thereby driving the outer rotating shell 1 to rotate. When the drive coil 3 generates an alternating magnetic field, the alternating magnetic field passes through the generator coil 4, generating a first current in the generator coil 4. At this time, since the outer rotating shell 1 is rotating with the permanent magnet, the changing magnetic field generated by the permanent magnet passes through the generator coil 4 again, generating a second current in the generator coil 4. The dual-current power generation is achieved through the permanent magnet, and the power generation is greatly increased by utilizing the superposition of the two currents.

[0017] In use, the inner stator assembly remains stationary. After the drive coil 3 is energized with alternating current, multiple permanent magnet blocks 2 are subjected to magnetic force, causing the outer rotating housing 1 to rotate. The rotation of the outer rotating housing 1 drives the non-outgoing end cover 6 and the bearing to rotate synchronously. The bearing connects to the wheel hub of the new energy vehicle, enabling the vehicle to move. The outer side of the outgoing end cover 5 is fixedly connected to the new energy vehicle via bolts or other connectors. The inner side of the outgoing end cover 5 is fixedly connected to the bracket 7 to maintain the stability of the bracket 7, thereby ensuring the stability of the inner stator assembly. The permanent magnet dual-current generator of this invention can generate electricity through dual currents without affecting the normal rotation of the wheel hub of the new energy vehicle. Example
