[0053] It should be noted that in the following description, the same or similar reference numerals in different embodiments represent the same or similar features.

[0054] Figures 1 to 7 It shows a generator assembly 10 according to a first preferred embodiment of the present invention. The generator assembly 10 includes a rotatable fan 12 having fan blades 14, and at the distal end 11 of the fan blades 14 there are blade magnets 16. The generator assembly 10 further includes a main pipe 30 having a coil 32 and internally accommodating a movable magnet 34. The distal end 38 of the main pipe 30 is provided with a recoil magnet 36, and the recoil magnet 36 biases the movable magnet 34 towards the proximal end 40 of the main pipe 30. The fan 12 rotates under the action of wind / airflow / fluid flow during use, which causes the blade magnets 16 to interact with the movable magnet 34, enabling the movable magnet 34 to reciprocate inside the main pipe 30 through the coil 32, thereby generating an electric current in the coil 32.

[0055] In an exemplary embodiment, the rotatable fan 12 includes a central hub 13 and two fan blades 14 extending outwardly from the hub 13. The hub 13 rotates about an axis 15. The fan blades 14 include a curved front surface 17 from a leading edge 18 to a trailing edge 19. The fan blades 14 also include a flat rear surface 20 to which a blade magnet 16 is attached at a distal end thereof. The front surface 17 is shaped such that the fan 12 can rotate about the axis 15 with the wind, air flow or liquid flow.

[0056] The main pipe 30 includes an elongated hollow body having an inner cavity 31, a proximal end 40 and a distal end 38. The proximal end 40 is disposed near the distal end 11 of the blade 14, and the direction of the main pipe 30 is parallel to the axis 15 of the hub 13.

[0057] A coil 32 is provided at a position on the main pipe 30 spaced from the proximal end 40. The coil 32 has a central opening aligned with the inner cavity 31. A movable magnet 34 is placed inside the inner cavity 31 and can move freely between the proximal end 40 and the distal end 38 of the inner cavity 31, thus passing through the central opening of the coil 32. The proximal end cap 42 closes the proximal end 40.

[0058] The distal end 38 of the main pipe 30 includes a recoil magnet regulator 60. The regulator 60 includes a threaded rod 62, with a recoil magnet 36 provided at one end and a handle 64 provided at the other end. Rotating the handle 64 can adjust the position of the recoil magnet 36 in the main pipe 30, i.e., the distance between the recoil magnet 36 and the proximal end 40.

[0059] The recoil magnet 36 is used to bias / reject the movable magnet 34 towards the proximal end 40 and close to the proximal end cap 42. The blade magnet 16 is arranged such that the blade magnet 16 can rotate around and close to the proximal end cap 42, so that the blade magnet 16 interacts with the movable magnet 34 and pushes / rejects the movable magnet 34 away from the proximal end cap 42.

[0060] For example, the recoil magnet 36 can have its north pole facing the proximal end cap 42. The movable magnet 34 can have its north pole facing the recoil magnet 36 and its south pole facing the proximal end cap 42. The blade magnet 16 can have its south pole facing the proximal end cap 42.

[0061] When the wind, air flow or liquid flow acts on the fan 12, the fan 12 rotates, and the blade magnet 16 passes through the proximal end cap 42 at set time intervals. During these time intervals, the corresponding blade magnet 16 close to the proximal end cap 42 pushes / rejects the movable magnet 34 away from the proximal end cap 42, causing the movable magnet 34 to pass through the coil 32. After the blade magnet 16 passes through, the recoil magnet 36 returns / rejects the movable magnet 34 to its initial position close to the proximal end cap 42, at which time the movable magnet 34 passes through the coil 32 in the opposite direction.

[0062] The continuous rotation of the fan 12 causes the movable magnet 34 to reciprocate through the coil 32, thereby generating an electric current in the coil 32 through electromagnetic induction. The intensities of the magnets 16, 34, and 36 can be...

[0063] Electromagnetic induction is based on Faraday's law of electromagnetic induction. It involves the relative motion (rotation or linear motion) of a magnet with respect to a coil (electromagnet), resulting in a change / interruption in the magnetic field (flux) associated with the magnet and the coil, thereby generating an electromotive force (e.m.f.) / current. The following figure shows the linear motion of a magnet entering and leaving a coil.

[0064]

[0065] The amount of electric power generated depends on the strength of the magnetic field, the relative motion speed of the magnet and the coil, and the number of turns of the coil. Electromagnetic induction within a generator is initiated by the kinetic energy in a moving energy source (system) through the rotational or linear motion of specific parts of the generator.

[0066] Rotary generators are more common and mature in kinetic energy collection. Fleming's right-hand rule can be used to determine the direction of the induced current. In the case of a rotary generator, the direction of the induced current depends on the orientation of the rotating conductor plate. The magnitude of the induced current depends on the angle of deflection of the magnetic field caused by the rotation of the conductor plate. The larger the angle of deflection, the larger the magnitude of the current (e.m.f.). Formula (3) shows the formula for determining the magnitude of the induced current. According to Lenz's law, the negative sign represents the reaction force against the moving force. Lenz's law is consistent with Newton's third law and the law of conservation of energy.

[0067] Magnitude of the induced electromotive force (volts) = -N

[0068] where N represents the number of turns of the coil, Φ represents the magnetic flux (external magnetic field multiplied by the area of the coil), and t represents time.

[0069] In an improved embodiment of the assembly 10, a first piezoelectric sheet is provided at the proximal end cap 42, which will be repeatedly struck by the movable magnet 34 during use, thereby generating additional current. A second piezoelectric sheet can also be added inside the cavity 31, on the other side of the coil 32 opposite to the proximal end cap 42, such that the movable magnet 34 will strike the second piezoelectric sheet when leaving the proximal end cap 42 and will strike the first piezoelectric sheet when returning to the proximal end cap 42, thereby additional current can be generated. The current generated by the coil 32 and the piezoelectric sheets can be measured, collected, or used as needed.

[0070] The piezoelectric effect refers to the phenomenon that when mechanical strain and / or stress are applied to an electroactive material, electric charges are generated inside the material. The magnitude of the mechanical strain and / or stress applied to the electroactive material is proportional to the electric polarization intensity inside the material. A piezoelectric transducer is composed of an electroactive material with high electromechanical coupling performance. For example, barium titanate (BaTiO3), zinc oxide (ZnO), lead zirconate titanate (Pb[ZrxTi 1-x O3), and polymer-ceramic composites (PVDF-PZT). Polymer-ceramic composites have gradually replaced ceramics due to their flexibility, low cost, and durability. The 31 mode is usually used, although its coupling coefficient is low. Piezoelectric operation is based on the voltage constraint or charge constraint method. Kazmierski proposed the continuous equation of piezoelectric materials and the calculation formulas for voltage source, piezoelectric damping coefficient, optimal resistance, and maximum power.

[0071] Figures 8 to 13 Shown is a generator assembly 10b according to a second preferred embodiment of the present invention, which has components similar to those of the first embodiment. The generator assembly 10b also includes a rotatable fan 12, and at the distal end 11 of the fan blades 14 of the fan 12, there are blade magnets 16. The assembly 10 also includes a main pipe 30 provided with a coil 32, and a movable magnet 34 inside the main pipe 30. The main pipe 30 also has a recoil magnet 36.

[0072] In this example, the rotatable fan 12 also includes a central hub 13 and two fan blades 14 extending outward from the central hub 13. The hub 13 rotates about an axis 15 through a shaft 70 supported by a cowling housing 75. The cowling housing 75 forms an inlet leading to the fan 12 to direct wind, air flow, or liquid flow to the fan 12, causing the fan 12 to rotate about the axis 15. The fan 12 can have any number of blades, such as 3 or more, and at the distal end of each blade, there is a blade magnet 16, or there is a blade magnet 16 on every other blade. If necessary, balance weights can be added to other blades.

[0073] Same as the first embodiment, the main pipe 30 is parallel to and offset from the axis 15 such that the proximal end 40 of the main pipe 30 is close to the distal end of the fan blade 14 having the blade magnet 16. Offsetting the main pipe 30 from the axis 15 of the fan 12 can minimize the interference of the main pipe on the air flow passing through the fan 12.

[0074] The main pipe 30 is provided with a coil 32. The movable magnet 34 is placed inside the inner cavity 31 and can move freely inside the inner cavity 31 and pass through the central opening of the coil 32. The distal end 38 of the main pipe 30 also includes a recoil magnet regulator 60.

[0075] Similar to the first embodiment, when wind or air flow acts on the fan 12, the fan 12 rotates, causing the blade magnets 16 to pass through the proximal end cap 42 at set time intervals. During these intervals, the corresponding blade magnets 16 near the proximal end cap 42 push the movable magnet away from the proximal end cap 42, causing the movable magnet 34 to pass through the coil 32. After the blade magnet 16 passes through, the recoil magnet 36 returns the movable magnet 34 to its initial position near the proximal end cap 42, at which time the movable magnet 34 passes through the coil 32 in the opposite direction.

[0076] The continuous rotation of the fan 12 causes the movable magnet 34 to reciprocate through the coil 32, thereby generating an electric current in the coil 32 through electromagnetic induction.

[0077] The fans described in the embodiments of the present invention include any variants of components having a rotatable hub and blades, such as blades, impellers, turbines, rotors, etc., which can be rotated by wind, air flow, water flow, liquid flow, etc.

[0078] In other embodiments, the fan can be replaced by an actively rotating component (such as a wheel or a flywheel). For example, in this embodiment, the generator assembly is an additional component of an internal combustion engine.

[0079] In another possible improvement, the assembly 10 can include two or more main pipes 30, each main pipe being provided with a coil 32 and accommodating a movable magnet 34. A piezoelectric pad can also be provided at the end of the travel of the movable magnet of each main pipe. For example, the main pipes can be placed at opposite positions on the circumferential edge of the fan blade movement. The main pipes can also include two or more spaced coils, and such an embodiment can generate more current. The assembly can also include additional devices, such as a voltage regulator and a current regulator, to regulate the generated electricity.

[0080] The magnets can also be placed in other parts of the blade, such as the middle of the blade. Each blade magnet can correspond to a separate corresponding main pipe. Each blade can be equipped with two or more blade magnets, for example, one at the distal end and another in the middle, and be equipped with corresponding main pipes.

[0081] The generators in the above embodiments can be used to charge the batteries of any electric mobile vehicle moving in air or water. For example, the generator assembly 10 can be installed on the car roof or above the motor hood, and when the vehicle moves, the fan 12 rotates with the air flow. The generator assembly 10 can also be integrated into the vehicle body. For example, two assemblies 10 can be installed on each side of the vehicle body respectively.

[0082] Other possible means of transportation include trucks, bicycles, boats, trains, airplanes, etc. As long as the vehicle is in motion, the generator assembly can be used to charge the vehicle battery, capacitor, or for the operation of low-current electronic devices (such as heating, audio, lighting, etc.). The vehicle can be an electric vehicle or an internal combustion engine vehicle.

[0083] The above generator assembly has fewer moving parts and lower maintenance requirements.

[0084] The generator assembly 10 can also be adapted to other applications where other forces are used to rotate the fan 12. For example, the assembly 10 can be used in tidal applications, where the flow of water (water current) is utilized to rotate the blades and generate electricity. All components are waterproofed according to the application environment. In this embodiment, the fan 12 can be replaced with an impeller or other rotors suitable for fluid applications.

[0085] The generator can also be used in flywheel applications, where the rotating fan will generate electricity in the form of a flywheel, mechanically, or otherwise. Such a generator can also be connected to a low-torque motor to generate electricity instead of the blades.

[0086] The generator assembly can also be used in static applications, where the generator assembly is installed at a high wind speed location, such as the roof of a building. The fan can also be replaced with a vertical blade impeller. In these embodiments, the fan magnet and the main pipe are placed at a suitable remote location.

[0087] The generator assembly includes two piezoelectric wafers at both ends of the main pipe and the coil, adding a duality to the power generation of the device.

[0088] The above generator is scalable and capable of generating low voltage (LV), medium voltage (MV), and high voltage (HV).

[0089] The above new motor / generator assembly reproduces the original motor design, integrating the blades with the actual motor / generator assembly. Placing the "motor" (main pipe) away from the center provides good air flow throughout the turbine body.

[0090] Each rotation of the fan / turbine generates electricity. Since it does not require as high a rotational speed as other generators to generate electricity, the above design is efficient.

[0091] The above generator can operate in low-speed and high-speed applications. The generator can be adjusted at different vehicle speeds to generate electricity.

[0092] Although the preferred embodiments of the present invention have been described, it will be obvious to those skilled in the art to make modifications to the illustrated embodiments.

[0093] The number, position, and orientation of the main tube, coil, piezoelectric sheet, and magnet can all be adjusted or moved as needed to suit different applications. For example, the blade magnet can be located in the middle of the blade instead of at the distal end.

[0094] In another possible improvement, the orientation of the blade magnet on the blade can be parallel or perpendicular to the axis of rotation of the fan (e.g., perpendicular to the rear surface of the blade). In this embodiment, the main tube is oriented to extend radially from the axis of rotation. The blade magnet will thus push the movable magnet away from the central axis of rotation outward. The main tube can be placed at any radial position, horizontal, vertical, or in any radial direction at an angle.

[0095] Figure 14 A generator assembly 10c according to a third preferred embodiment of the present invention is shown. The generator assembly 10c includes a plurality of generator sub-assemblies 9a to 9d arranged in series.

[0096] Each generator sub-assembly 9 includes a rotatable fan 12 with blade magnets on its fan blades. Each sub-assembly 9 also includes at least one main tube 30. The main tube 30 is provided with a coil 32, a movable magnet 34 is provided inside, and a recoil magnet 36 is provided at the distal end 38 of the main tube 30. The function of each generator sub-assembly 9 is similar to that of the above-mentioned generators 10 and 10b, and can also include piezoelectric sheets to generate additional current.

[0097] Sub-assembly 9a includes two main tubes 30a. The directions of the two main tubes 30a are parallel to the axis 15 of the hub 13. The two main tubes 30a are placed on opposite sides of the axis 15. Sub-assembly 9a also includes a motor 80, which can be used as a starting motor to start the rotation of the fan 12. After that, the air flow or liquid flow can drive the fan 12 to rotate. Once the fan 12 is driven to rotate by the air flow or fluid flow, the motor 80 can also operate as an additional generator. The main tube 30 can also include a plurality of spaced coils 12 as shown.

[0098] Sub-assemblies 9b to 9d show that the blade magnets are positioned on the fan blades, and the magnetic poles (sides) of the blade magnets face away from the axis of rotation of the fan (e.g., placed on the outer peripheral part of the fan blade). In this embodiment, the main tube 30b extends radially outward relative to the axis of rotation 15. Therefore, the blade magnet repels the movable magnet outward from the central axis of rotation 15. The main tube 30b is supported by a bracket 82 and can be set at any radial position, horizontally, vertically, or in any radial angular direction relative to the axis of rotation.

[0099] Subassemblies 9b to 9d each show one or more radially oriented main pipes 30b, and the fan structures of subassemblies 9b to 9d are different. The fan structure can be made bidirectional, that is, moved / rotated by flow in either axial direction (backward or forward), which is ideal for tidal applications. Magnets 16 can be embedded in the blades to reduce friction as shown in the case of magnet 16b.

[0100] The generator subassemblies 9a to 9d are arranged in series, and the axes 15 of their fan hubs are aligned. Therefore, the air flow or fluid flow acts on the fans in series. The axes of the fans can be connected to each other or independent of each other.

[0101] Figure 15 A generator assembly according to a fourth preferred embodiment of the present invention is shown. In this embodiment, the fan is replaced by a rotatable arm 86, with a magnet 16 at the distal end of the arm 86. The arm 86 is rotated by a motor 90, which is powered by a battery. The recoil magnet adjuster 60 can also be a motor that pushes a plunger of the recoil magnet.

[0102] Thus, the above embodiment shows that the generator can initially work by a "starter motor" by using a one-way bearing to rotate with the wind flow to overcome the magnetic torque and start the magnets of the generator. Once the rotor blades start to rotate, the connected shaft rotates unhindered within the bearing coupling, generating electricity under the action of wind / water etc.

[0103] When using gas / fluid / water pipe flow, no "starter motor" is required. The movable magnet is located on the outside and then moves inwards in an oscillating manner.

[0104] The movable recoil magnet can be controlled by a motor to adjust the position of the recoil magnet using a threaded or linear method.

[0105] The generator assembly produces a "knocking sound" (impact noise) when generating electricity at low speeds, but is almost silent at high speeds (from impact piezoelectricity to vibration resonance).

[0106] The assembly may include a combination of axial and radial coil arrangements. Each fan may include a combination of magnets parallel to the axis (with corresponding main tubes also parallel to the axis) and magnets facing away from the axis (with corresponding main tubes extending radially outward from the axis).

[0107] The coil piston can be connected to the recoil magnet, the threaded sleeve, the sliding mechanism connected to the motor and the movable magnet to form the end of the coil assembly. The copper coil side forms the front end of the coil assembly.

[0108] The coil arrangement may include one or more coil windings on / along the main tube of the coil arrangement.

[0109] The coil device around / inside can be a multiple of 2 or 3, etc. (i.e., 2 - coil configuration, 4 coils, 6 coils, 8, 10, 12, etc.).

[0110] One or more magnets can be placed at intervals along the length direction of each blade to correspond to each individual coil device.

[0111] The blade configuration in the blade can be axial, radial or a combination of both. For example: The magnets can be oriented in the blade to repel the movable magnets axially and radially.

[0112] For a tidal turbine, the magnets in the blade can be oriented to be close to other magnets rotating on the radial axis, repelling each individual coil device located on the diameter of the axis of the rotating blade. Variants of the tidal generator assembly can have or not have a piezoelectric generator and have bidirectional blades.

[0113] The generator can generate electricity with or without a starting motor. When the end magnets are in the most extreme positions in the coil assembly, the torque will be low enough for the turbine to rotate.

[0114] It should be noted that the present invention can also be applied to other configurations, such as replacing the fan with an impeller having magnets, or a flywheel having magnets or other rotating components.

[0115] In another possible improvement, the main pipe can be vertically oriented, the return biasing method can be gravity, and the return magnet can be removed.
