Description

Technical Field

[0001] This invention relates to a large-angle swing-type power generation device, belonging to the field of power generation technology. Background Technology

[0002] Oscillating generators are typically used to convert the kinetic energy generated by the oscillation of an object into electrical energy. A Chinese patent (patent number 201510674669.3) entitled "Oscillating Generator" includes a housing, a magnetic rod fixed to the housing, and a coil fitted onto the magnetic rod. The housing has a first conductive rail and a second conductive rail fixed parallel to the axis. One end of the coil has a first conductive slider that slides along the first conductive rail, and the other end of the coil has a second conductive slider that slides along the second conductive rail. Its advantage is that it can be used to charge other portable electronic devices such as smartwatches, improving the convenience of using mobile electronic products. However, it also has the following disadvantages: the coil's movement distance is relatively short, making it only suitable for high-frequency oscillations at small angles. When the oscillation angle is large, the coil cannot move due to the limitation of the magnetic rod's length, thus limiting the conversion of large amounts of kinetic energy into electrical energy, resulting in limited electrical energy generation, low conversion efficiency, and limited application range. Summary of the Invention

[0003] The purpose of this invention is to provide a large-angle swing-type power generation device, which solves the problems of existing technologies that can only be used for high-frequency swing at small angles, cannot convert a large amount of kinetic energy into electrical energy, have limited electrical energy generation, low conversion efficiency, and limited application range.

[0004] The above-mentioned technical objective of the present invention is mainly achieved through the following technical solution: a large-angle swing-type power generation device, comprising a bushing fitted on a non-rotating shaft, a swing assembly provided on the radially outer side of the bushing, the swing assembly comprising at least a housing indirectly or directly rotatably supported on the bushing, the inner wall of the housing and the circumferential surface of the bushing forming an annular swing cavity, two opposing annular magnets fixed on the two axially opposite sidewalls of the swing cavity, the two opposite end faces of the two annular magnets being N pole and S pole respectively, the axis of the annular magnets coinciding with the axis of the bushing, a coil assembly located in the swing cavity provided on the radially outer side of the bushing, the coil assembly comprising at least a coil indirectly or directly fixedly supported on the bushing, the coil being located between the two opposite end faces of the two annular magnets.

[0005] When using the device of this invention, it is first installed in the inner hole of a swinging object, and the bushing in the device is fixedly installed on a non-rotating shaft. The swinging object can be a swinging wave energy device, a swing, a clock, etc. When the swinging object swings, the shell will rotate relative to the bushing, thereby driving two ring magnets to swing around the axis of the bushing. At this time, the coil assembly remains stationary, and the coil is located between the two opposite end faces of the two ring magnets, so that the coil in the coil assembly can cut the magnetic field lines to convert the kinetic energy generated by the swing into electrical energy for power generation. This invention achieves large-angle swing by causing the ring magnets and the coil to move relative to each other so that the coil cuts the magnetic field lines and the ring magnets swing around the bushing. The swing angle is not limited, so the kinetic energy generated by the swing can be fully utilized to convert a large amount of kinetic energy into electrical energy, resulting in high conversion efficiency and wide application range.

[0006] Preferably, the coil extends 180° parallel to the circumference of the annular magnet to form a semi-circular ring, and the projection of the annular center line of the coil onto the end face of the annular magnet coincides with the projection of the annular center line of the annular magnet.

[0007] By extending the coil 180° parallel to the circumference of the ring magnet to form a semi-circular ring, and ensuring that the projection of the coil's ring centerline onto the end face of the ring magnet coincides with the projection of the ring magnet's ring centerline onto the end face of the ring magnet, the coil is always positioned between the two opposite end faces of the two ring magnets when the ring magnet rotates around the bushing. This ensures that the coil can cut magnetic field lines whenever the ring magnet swings, and the coil remains in a state of cutting magnetic field lines throughout the swing process, so as to fully utilize the kinetic energy generated by the swing and further improve the efficiency of power generation.

[0008] Preferably, the outer diameter of the coil cross-section is equal to the radial width of the annular magnet.

[0009] By setting the outer diameter of the coil cross-section to be equal to the radial width of the toroidal magnet, the coil has the largest possible cutting area when the toroidal magnet swings, which can fully cut the magnetic field lines to ensure the efficiency of power generation. Furthermore, the coil diameter can be minimized while maximizing the power generation efficiency, thereby achieving the lowest possible cost while maximizing the coil cutting effect.

[0010] Preferably, multiple sets of the coil assemblies are arranged side by side along the axial direction of the bushing.

[0011] By arranging multiple sets of coil assemblies side by side along the axial direction of the bushing, it is possible to generate electricity from multiple points simultaneously, thereby increasing the power output.

[0012] Preferably, the coil assembly further includes a mounting ring fixed to the bushing, the outer circumference of the mounting ring having at least two spaced mounting brackets, and the two mounting brackets having fixed support rings for mounting the coil.

[0013] The coil assembly is further provided with a mounting ring fixed to the bushing. The outer ring of the mounting ring has at least two spaced mounting brackets. Support rings for mounting the coil are fixedly supported on the two mounting brackets, so that the coil can be mounted on the support rings. The two mounting brackets on the mounting ring form a fixed support with the bushing, thereby fixing the coil to the radial outside of the bushing, so that the coil can remain stationary to cut the magnetic field lines when the ring magnet swings.

[0014] Preferably, the support ring extends 180° parallel to the circumference of the annular magnet to form a semi-circular ring, the cross-sectional shape of the support ring is a circular ring, the projection of the annular center line of the support ring onto the end face of the annular magnet coincides with the projection of the annular center line of the annular magnet, and the coil is spirally wound around the radial outer side of the support ring along the length direction of the support ring.

[0015] By extending the support ring 180° parallel to the circumference of the annular magnet to form a semi-circular ring, the cross-sectional shape of the support ring is circular. The projection of the annular centerline of the support ring onto the end face of the annular magnet coincides with the projection of the annular centerline of the annular magnet. The coil is spirally wound around the radial outer side of the support ring along its length. This ensures that the annular centerline of the coil spirally wound around the radial outer side of the support ring coincides with the projection of the annular centerline of the annular magnet onto the end face of the annular magnet, thus ensuring the cutting effect and the efficiency of power generation. In addition, the hollow interior of the support ring saves materials and reduces its own weight, thereby reducing the stress on the mounting bracket and bushing side, so as to achieve stable support for the coil over a long period of time.

[0016] Preferably, the two mounting brackets are arranged 180° apart circumferentially along the mounting ring. The end of the mounting bracket away from the circumferential surface of the mounting ring is formed with an arc-shaped portion that is adapted to the surface of the support ring. The arc-shaped portion extends at an angle greater than 180°, and the two arc-shaped portions respectively form fixed supports with the two ends of the support ring.

[0017] By setting two mounting brackets 180° apart circumferentially around the mounting ring, an arc-shaped portion adapted to the surface of the support ring is formed at the end of the mounting bracket away from the circumferential surface of the mounting ring. The arc-shaped portion extends at an angle greater than 180°. The two arc-shaped portions form fixed supports with the two ends of the support ring respectively, so that the arc-shaped portion can fit tightly with the surface of the support ring to achieve stable support for the support ring. At the same time, it can also achieve a limiting effect on the support ring, resulting in better fixed support. In addition, it can minimize the connection points between the arc-shaped portion and the support ring, thereby reducing the impact of the arc-shaped portion on the coil cutting area, so that the coil can continuously and fully cut the magnetic field lines.

[0018] Preferably, each of the two mounting brackets has a terminal block fixed on it, and the two ends of the coil are connected to the corresponding terminal block.

[0019] By fixing terminals on two mounting brackets, the two ends of the coil are connected to the corresponding terminals, so that the current generated in the coil can be conducted out through the wires connected to the terminals, and finally converted into the required electrical energy.

[0020] Preferably, the inner wall of the bushing has two concave wiring grooves that penetrate both axial ends of the bushing. The two wiring grooves are spaced 180° apart circumferentially along the bushing. The bushing has two radially penetrating wiring holes. The inner ends of the two wiring holes are connected to the corresponding wiring grooves, and the outer ends of the two wiring holes are connected to the swing cavity. The axes of the two wiring holes coincide with the center lines in the width direction of the corresponding wiring grooves. The center lines in the width direction of the two wiring grooves coincide with the center lines in the thickness direction of the corresponding mounting brackets. The two wiring holes are located near the same axial outer end of the mounting ring.

[0021] Two concave wiring grooves are formed on the inner wall of the bushing, extending through both axial ends of the bushing. The two wiring grooves are spaced 180° apart circumferentially around the bushing. The bushing has two radially penetrating wiring holes. The inner ends of the two wiring holes are connected to the corresponding wiring grooves, and the outer ends of the two wiring holes are connected to the swing cavity. The axes of the two wiring holes coincide with the center lines in the width direction of the corresponding wiring grooves, and the center lines in the width direction of the two wiring grooves coincide with the center lines in the thickness direction of the corresponding mounting brackets. The two wiring holes are located near the same axial outer side of the mounting ring, allowing the wires connected to the two terminals to pass through the near-end wiring holes into the corresponding wiring grooves and finally exit from the opening end of the wiring grooves to connect with an external conversion device to output the required electrical energy. In addition, the distance between the wiring hole and the corresponding terminal is kept as short as possible to reduce the length of the wires and prevent interference with the swing assembly due to excessively long wires, thus reducing the kinetic energy generated by its swing.

[0022] Preferably, the housing includes two end caps spaced axially along the bushing and an annular outer shell detachably fixed between the two end caps. The end caps are disc-shaped and rotatably supported on the bushing by bearings. The inner ends of the two end caps are respectively formed with concave annular grooves. The axis of the annular grooves coincides with the axis of the bushing. The two annular magnets are respectively embedded in the corresponding annular grooves.

[0023] The device comprises two end caps spaced axially along the bushing within the housing, and an annular outer shell detachably fixed between the two end caps. The end caps are disc-shaped and rotatably supported on the bushing by bearings. The inner ends of the two end caps each form a concave annular groove, the axis of which coincides with the axis of the bushing. Two annular magnets are respectively embedded in their corresponding annular grooves. When the housing rotates around the axis of the bushing, it can drive the two annular magnets to swing synchronously, thereby achieving relative movement between the annular magnets and the coil. Furthermore, the precise installation of the two annular magnets within their corresponding annular grooves ensures alignment between the annular centerline of the magnet and the annular centerline of the coil. Additionally, the housing is an assembly structure, allowing for the replacement of components such as the annular magnets and coils within the swing cavity by disassembling the annular outer shell, thus extending the device's service life.

[0024] Therefore, by causing relative motion between the ring magnet and the coil to cut magnetic field lines, and by having the ring magnet rotate around the bushing, the present invention can achieve large-angle swinging, and the swinging angle is not limited. Thus, the kinetic energy generated by the swinging can be fully utilized to convert a large amount of kinetic energy into electrical energy, resulting in high conversion and power generation efficiency and a wide range of applications.

[0029] like Figure 1As shown, the large-angle swing-type power generation device of the present invention includes a bushing 1 fitted onto a non-rotating shaft. The bushing 1 is an axially penetrating cylindrical shape and is interference-fitted onto the non-rotating shaft. A swing assembly 2 is provided on the radially outer side of the bushing 1.

The two opposite end faces of the two annular magnets 5 are the N pole and the S pole, respectively. The axis of the annular magnets 5 is perpendicular to the bushing 1. The axes of the two end caps 12 are coincident. The housing 3 includes two end caps 12 spaced apart along the axial direction of the bushing 1 and an annular outer shell 13 detachably fixed between the two end caps 12. The inner ends of the two end caps 12 are connected to the two ends of the annular outer shell 13 along the axial direction by screws. The end caps 12 are disc-shaped and are rotatably supported on the bushing 1 by bearings. The outer ring of the bushing 1 is interference-fitted with the inner ring of the bearing, and the inner ring of the end cap 12 is interference-fitted with the outer ring of the bearing. The inner ends of the two end caps 12 are respectively formed with concave annular grooves 14. The axis of the annular grooves 14 coincides with the axis of the bushing 1. Two annular magnets 5 are respectively embedded in the corresponding annular grooves 14. The annular magnets 5 are interference-fitted in the annular grooves 14.

[0030] like Figure 1 and Figure 2 As shown, a coil assembly 6 is provided on the radial outer side of the bushing 1, located in the swing cavity 4. Multiple sets of coil assemblies 6 are arranged side by side along the axial direction of the bushing 1, and the multiple sets of coil assemblies 6 are spaced apart along the axial direction of the bushing 1. The coil assembly 6 includes at least a coil 7 that is indirectly or directly fixed and supported on the bushing 1. The coil 7 is located between the two opposite end faces of the two annular magnets 5. The coil 7 extends parallel to the annular magnet 5 by 180° to form a semi-circular ring. The coil 7 can also extend to any angle less than 180°. The annular center line of the coil 7 coincides with the projection of the annular center line of the annular magnet 5 onto the end face of the annular magnet 5. The outer diameter of the cross section of the coil 7 is equal to the radial width of the annular magnet 5. The outer diameter of the cross section of the coil 7 can also be less than or greater than the radial width of the annular magnet 5.

[0031] like Figure 1 and Figure 2As shown, the coil assembly 6 also includes a mounting ring 8 fixed to the bushing 1. The inner ring of the mounting ring 8 is interference-fitted with the outer ring of the bushing 1. The outer ring of the mounting ring 8 forms at least two spaced mounting brackets 9. Supporting rings 10 for mounting the coil 7 are fixedly supported on the two mounting brackets 9. The supporting rings 10 extend 180° parallel to the circumference of the annular magnet 5 to form a semi-circular ring. The extension angle of the supporting rings 10 is the same as the extension angle of the coil 7. The cross-sectional shape of the supporting rings 10 is circular. The annular center line of the supporting rings 10 coincides with the projection of the annular center line of the annular magnet 5 onto the end face of the annular magnet 5. The coil 7 is mounted along the supporting rings 10. The length direction of the coil 10 is spirally wound around the radial outer side of the support ring 10. The winding shape is circular or semi-circular. Two mounting brackets 9 are set at 180° intervals along the circumference of the mounting ring 8. An arc-shaped portion 11 adapted to the surface of the support ring 10 is formed at the end of the mounting bracket 9 away from the circumferential surface of the mounting ring 8. The arc-shaped portion 11 extends at an angle greater than 180°. The two arc-shaped portions 11 form fixed supports with the two ends of the support ring 10 respectively. The arc-shaped portion 11 is connected to the support ring 10 by screws. A terminal 15 is fixed on each of the two mounting brackets 9. The two ends of the coil 7 are connected to the corresponding terminal 15 respectively.

[0032] like Figure 1 As shown, the inner wall of the bushing 1 has two concave wiring grooves 16. The cross-sectional shape of the wiring grooves 16 is rectangular. The wiring grooves 16 penetrate through both ends of the bushing 1 in the axial direction. The two wiring grooves 16 are arranged at 180° intervals along the circumference of the bushing 1. The bushing 1 has two radially penetrating wiring holes 17. The inner ends of the two wiring holes 17 are respectively connected to the corresponding wiring grooves 16. The outer ends of the two wiring holes 17 are respectively connected to the swing cavity 4. The axes of the two wiring holes 17 coincide with the center line in the width direction of the corresponding wiring grooves 16. The center lines in the width direction of the two wiring grooves 16 coincide with the center line in the thickness direction of the corresponding mounting bracket 9. The two wiring holes 17 are located at the near end position on the same axial outer side of the mounting ring 8. The near end position must ensure that the vertical distance between the axis of the wiring hole 17 and the axial end face of the mounting ring 8 is greater than the radius of the wiring hole 17.

[0033] In this specific implementation, the device of the present invention is first installed in the inner hole of the swinging object, and the bushing in the device of the present invention is fixedly installed on the non-rotating shaft. The swinging object can be a swinging wave energy device, a swing, a clock, etc. When the swinging object swings, the housing 3 will rotate relative to the bushing 1, thereby driving the two annular magnets 5 to swing around the axis of the bushing 1. At this time, the coil assembly 6 remains stationary, and the coil 7 is located between the two opposite end faces of the two annular magnets 5. At the same time, the annular center line of the coil 7 coincides with the projection of the annular center line of the annular magnet 5 on the end face of the annular magnet 5, so that the coil 7 in the coil assembly 6 can fully cut the magnetic field lines. The current generated on the coil 7 can be conducted out through the wire connected to the terminal 15, and finally converted into the required electrical energy. Thus, the kinetic energy generated by the swing can be converted into electrical energy for power generation.

[0034] This invention enables relative motion between a ring magnet and a coil, allowing the coil to cut magnetic field lines. The ring magnet also rotates around a bushing, achieving large-angle swings without limitation. This allows for the full utilization of the kinetic energy generated by the swings, converting a large amount of kinetic energy into electrical energy, resulting in high conversion efficiency and a wide range of applications.
