The electricity generated can be used to power electronic devices such as display screens, thereby improving the intelligence level of the spinning bike. The planetary gear set effectively reduces the rotational speed of the shaft and increases the torque, allowing the rotating generator to generate stable electricity at a lower speed. At the same time, the design of the wedge overrunning clutch prevents the influence of the shaft reversal on the planetary gear set, thereby improving the stability and durability of the system. The bicycle frame, generator, and resistance adjustment unit all adopt a modular design. This integrated design facilitates assembly and maintenance, saves floor space, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of those skilled in the art, the present application will be further described below in conjunction with the embodiments and drawings, and the content mentioned in the embodiments is not a limitation of the present application.

[0029] Please refer to Figures 1 to 8 The utility model discloses a dynamic bicycle with self -power generation function, including bicycle support 1, rotating shaft 2 of rotating setting on bicycle support 1 and the pedal 3 of being connected with rotating shaft 2, still include the power generation device 4 for generating electric energy, and the power generation device 4 includes the rotor housing 41 of cooperation and connection with rotating shaft 2, the stator unit 42 of setting on bicycle support 1 and being located in rotor housing 41 and the planetary gear set 43 of being connected with rotor housing 41, the inside of rotor housing 41 is equipped with the first magnetic part 411 of cooperation and use with stator unit 42, rotating shaft 2 is connected with rotor housing 41 through planetary gear set 43,

[0030] Bicycle support 1 still is equipped with central control module (not shown in drawing) and the resistance adjusting unit 5 of being connected with central control module, stator unit 42 is electrically connected with central control module, and the user drives rotating shaft 2 to rotate through pedal 3 to make planetary gear set 43 drive first magnetic part 411 on rotor housing 41 relative stator unit 42 rotation and generate electric energy, and the electric energy of power generation device 4 supplies to central control module or stores for standby through the external power storage device of setting on bicycle support 1.

[0031] Specifically, when a user steps on pedal 3, pedal 3 drives shaft 2 to rotate. Shaft 2 is connected to rotor housing 41 via planetary gear set 43. Planetary gear set 43 converts the high-speed, low-torque rotation of shaft 2 into low-speed, high-torque rotation of rotor housing 41. A first magnetic member 411 (such as a permanent magnet) is mounted within rotor housing 41, while stator unit 42 is stationarily mounted on the bicycle frame and located within rotor housing 41.

[0032] As the rotor housing 41 rotates, the first magnetic member 411 moves relative to the stator unit 42. According to Faraday's law of electromagnetic induction, this relative motion generates a changing magnetic field in the stator unit 42, which in turn generates an induced electromotive force in the coil, ultimately forming a current through a closed circuit, thereby generating electrical energy. The central control module is responsible for collecting the electrical energy generated by the coil and performing preliminary processing (such as rectification and filtering) before transmitting it to the central control module. (In actual use, a battery can be connected to the output terminal of the central control module, and the output terminal of the battery is connected to the central control module or other electrical facilities on the bicycle stand 1.)

[0033] Specifically, the planetary gear set 43 includes a planetary carrier 431, three planetary gears 432, a sun gear 433 and a ring gear 434; the planetary carrier 431 is connected to the rotating shaft 2 through a wedge overrunning clutch 435 to prevent the rotating shaft 2 from driving the planetary gear set 43 to reverse, and the three planetary gears 432 are detachably connected to the planetary carrier 431 through bolts or pins. The three planetary gears 432 are arranged around the central axis of the planetary carrier 431. The planetary gears 432 are used in conjunction with the planetary carrier 431, and the rotating planetary carrier 431 drives the rotor housing 41 to rotate via the sun gear 433.

[0034] The sun gear 433 is bolted to the rotor housing 41. The rotor housing 41 is rotatably mounted on the rotating shaft 2 via two bearings. The generator 4 also includes a first housing 44 that covers the planetary gear set 43. This housing protects the internal gears from dust and impurities. A ring gear 434 is fixed to the inner wall of the first housing 44 and meshes with the planetary gears 432. The planetary gears 432 mesh between the ring gear 434 and the sun gear 433.

[0035] The sprag overrunning clutch 435 in this embodiment is a sprag overrunning clutch comprising an inner ring connected to the rotating shaft 2, an outer ring connected to the planetary carrier 431, and a specially shaped sprag located between the inner and outer rings. When the rotation direction of the inner ring (rotating shaft 2) is the same as the potential rotation direction of the outer ring (planetary carrier 431), and the speed of the inner ring is greater than that of the outer ring, the specially shaped sprag is compressed by the inner and outer rings, thereby transmitting torque, and the spinning bike is in a normal riding state. At this time, the user pedals the pedals 3 to rotate the rotating shaft 2, which is then transmitted to the planetary carrier 431 via the sprag overrunning clutch 435. The planetary carrier 431 then drives the sun gear 433 to rotate in conjunction with the rotor housing 41, causing the first magnetic member 411 within the rotor housing 41 to rotate relative to the stator unit 42.

[0036] When the inner ring (rotating shaft 2) changes direction (the user counter-steps on pedal 3) or its speed drops below that of the outer ring (planetary carrier 431) (the user's pedaling speed decreases), the friction between the shaped wedges and the inner and outer rings is insufficient to maintain their compression. At this point, the shaped wedges slide relative to the inner and outer rings, achieving an overrunning function. This means that the rotation of the inner ring does not drive the outer ring (rotating shaft 2 does not drive the planetary carrier 431). At this point, the spinning bike is not in a normal riding state. Allowing rotating shaft 2 to rotate freely relative to planetary carrier 431, or idling, effectively protects the planetary gear set 43 and rotor housing 41 from the effects of reverse torque. By preventing the transmission of reverse torque, components such as the planetary gear set 43 and generator 4 are effectively protected from damage. Furthermore, users no longer need to worry about adverse effects of reverse pedaling on the equipment, enhancing riding freedom and safety.

[0037] When tested under the same unloaded conditions, the no-load friction torque of the wedge overrunning clutch 435 is 10gf.cm, and the no-load friction torque of the roller one-way wedge overrunning clutch is 22gf.cm. This means that when the exercise bike is not in a power-generating state, that is, when it is idling or running at a low speed, the wedge overrunning clutch 435 can reduce unnecessary energy loss compared to the roller one-way wedge overrunning clutch, and the shaft connection is smoother, reducing noise and vibration caused by friction, thereby improving user comfort and enhancing transmission efficiency.

[0038] Specifically, the diameter of the planetary gears 432 is larger than the diameter of the sun gear 433. When the rotating shaft 2 rotates, the sun gear 433 drives the planetary gears 432 to revolve around it, while the planetary gears 432 also rotate on their own. This combined motion causes the planetary carrier 431 (and thus the rotor housing 41) to rotate at a lower speed, but significantly increases the torque, thereby helping the user achieve a fitness effect.

[0039] Specifically, the bicycle frame 1 is equipped with a U-shaped first support frame 6. This U-shaped design allows the other components of the generator 4 (such as the first cover 44, support ring 45, and rotor housing 41) to be arranged in an orderly manner on either side. This compact and rational layout helps reduce the overall volume and weight while improving the stability and durability of the system. The generator 4 also includes a support ring 45. The first cover 44 and support ring 45 are respectively arranged on either side of the first support frame 6. The stator unit 42 is fixed to the outer surface of the support ring 45. Bearings 46 are provided between the support ring 45 and the rotating shaft 2, between the first cover 44 and the rotating shaft 2, and between the rotor housing 41 and the rotating shaft 2. The use of bearings 46 reduces friction and wear between rotating components, thereby improving transmission efficiency. Furthermore, the design of the planetary gear set 43 further enhances power generation efficiency. The relative positions of the various components are clearly defined, making disassembly and installation easy, facilitating subsequent maintenance and servicing.

[0040] Specifically, the power generation device 4 further includes a second cover 47 mounted on the support ring 45. The second cover 47 covers the end of the stator unit 42 away from the rotor housing 41. The first cover 44 and the support ring 45 are both detachably connected to the first support frame 6. The second cover 47 is mounted on the support ring 45 and covers the end of the stator unit 42 away from the rotor housing 41. This design not only protects the stator unit 42 from external environmental damage (such as dust, moisture, and mechanical shock), but also helps improve the efficiency and stability of energy conversion.

[0041] Both the first cover 44 and the support ring 45 are detachably connected to the first support frame 6. This design allows users or maintenance personnel to inspect, replace, or upgrade internal components without disassembling the entire generator 4. It also facilitates assembly and commissioning during production. The stable operating environment of the stator unit 42 and the optimized transmission structure help improve energy conversion efficiency, allowing the spinning bike to generate more electricity during riding.

[0042] Specifically, multiple heat dissipation holes are provided on both the first and second housings 44, 47. During intense cycling, heat generated by the generator 4 is released through these holes, ensuring proper operation of the generator 4. In actual use, a small air cooler or other device can be installed on the first and second housings 44, 47, and powered by a battery connected to the generator 4, ensuring efficient energy utilization and stable operation of the generator 4.

[0043] Specifically, the rotor housing 41 is provided with a counterweight wheel 51 made of magnetically conductive material; the bicycle support 1 is provided with a resistance adjusting unit 5 for generating magnetic attraction force on the counterweight wheel 51, and is also provided with a touch operation screen 7 connected with the central control module, wherein the touch operation screen 7 is connected with the resistance adjusting unit 5 via the central control module; the user adjusts the magnetic attraction force of the resistance adjusting unit 5 on the counterweight wheel 51 through the touch operation screen 7 to change the rotational resistance of the counterweight wheel 51.

[0044] In the embodiment, the power generation device 4 is an outer rotor generator, and the rotor housing 41 of the outer rotor generator is directly connected with the counterweight wheel 51; compared with the structure of an inner rotor generator, the structure of the power generation device of the utility model is simpler, the mechanical transmission chain is simplified, and the manufacturing cost is saved. In addition, the structure also reduces the maintenance cost, because the number of transmission components is reduced, the potential failure points and wear sources are reduced.

[0045] Specifically, the bicycle support 1 is provided with an electromagnet connected with the central control module, and the touch operation screen 7 is connected with the electromagnet via the central control module; the user controls the current flowing through the electromagnet through the touch operation screen 7 to increase or reduce the magnetic force generated by the electromagnet to change the magnetic attraction force on the counterweight wheel 51; the electromagnet is the resistance adjusting unit 5.

[0046] In use, the user can adjust the current flowing through the electromagnet through the touch operation screen 7, and then adjust the magnetic force generated by the electromagnet through the central control module; the greater the magnetic force generated by the electromagnet, the greater the magnetic attraction force on the counterweight wheel 51, which promotes the counterweight wheel 51 to generate a force repelling the rotation direction of the counterweight wheel 51; because the counterweight wheel 51 is connected with the rotor housing 41, the rotor housing 41 is driven by the pedal 3 and the planetary gear set 43 through the rotating shaft 2, so the user needs to pedal the pedal 3 with greater force, thereby achieving the fitness effect of the user.

[0047] The precise control of the current flowing through the electromagnet through the control module can realize the precise adjustment of the cycling resistance to meet the exercise needs of different users; the response speed of the electromagnet to the current change is very fast, so the adjustment of the cycling resistance is also very fast, improving the user experience; the structure of the electromagnet and the counterweight wheel 51 is relatively simple, and there is no mechanical wear component, so the maintenance cost is low.

[0048] Specifically, the bicycle bracket 1 is provided with an arc-shaped first carrier frame 52, and a magnet member 53 is provided on the side of the first carrier frame 52 close to the counterweight wheel 51. One end of the first carrier frame 52 is movably set on the bicycle bracket 1, and the first carrier frame 52 is set around the outer wall of the counterweight wheel 51, and the magnet member 53 is used to magnetically adsorb the counterweight wheel 51; the other end of the first carrier frame 52 is connected to a driving member 54, and the driving member 54 is used to drive the first carrier frame 52 to drive the magnet member 53 close to or away from the counterweight wheel 51 to adjust the magnitude of the magnetic attraction between the magnet member 53 and the counterweight wheel 51; the driving member 54 is electrically connected to the central control module, and the touch operation screen 7 is connected to the driving member 54 via the central control module. The driving member 54, the first carrier frame 52 and the magnet member 53 are the resistance adjustment unit 5.

[0049] In this embodiment, the driving member 54 includes a second carrier 541 arranged on the bicycle frame 1, a rotating motor 542 arranged on the second carrier 541, a pull wire 545 wound around the output shaft of the rotating motor 542, and a compression spring 544 mounted on the pull wire 545; the free end of the pull wire 545 (the end away from the rotating motor) is connected to the first carrier 52, and the other end of the first carrier 52 is movably mounted on the support rod 543 to assist in positioning the first carrier 52, and the two ends of the compression spring 544 respectively contact the end faces of the first carrier 52 and the second carrier 541.

[0050] In actual use, the power access end of the rotating motor 542 can be connected to the above-mentioned central control module or battery or external power supply component, and the rotating motor 542 is connected to the central control module. When in use, the central control module can control the rotating motor 542 to pull the pull wire 545 to produce linear reciprocating movement, so that the pull wire pulls the magnet part 53 on the first carrier 52 close to or away from the counterweight wheel 51 made of magnetic material to achieve resistance adjustment.

[0051] The first carrier frame 52 is arranged in an arc shape and is arranged around the outer wall of the counterweight wheel 51. This design allows the magnet 53 to move along the contour of the counterweight wheel 51, keeping the magnetic force between the magnet 53 and the counterweight wheel 51 always effective and uniform. At the same time, the arc design also improves the stability and durability of the structure. This solution can accurately adjust the riding resistance of the spinning bike in real time to meet the exercise needs of different users. While adjusting the riding resistance, it also indirectly affects the load and speed of the generator, which helps to optimize the power generation efficiency. In actual use, a shock-absorbing element (such as a rubber pad, a spring, etc.) can be added between the drive member 54 and the first carrier frame 52 to reduce noise and vibration during the adjustment process.

[0052] The weight wheel 51 is made of a magnetic material, and a magnet 53 is provided on the first carrier 52. When the magnet 53 approaches the weight wheel 51, due to the attraction of the magnetic force, the weight wheel 51 will be subjected to an inward pulling force, and this pulling force is transmitted to the wheel of the spinning bike through the bicycle frame 1, thereby increasing the riding resistance. Conversely, when the magnet 53 moves away from the weight wheel 51, the magnetic force weakens and the riding resistance decreases accordingly. The driving member 54 (which can be an electric push rod, hydraulic cylinder, etc. in actual use) is connected to the other end of the first carrier 52. The user controls the driving member 54 by touching the touch screen 7 to drive the first carrier 52 and then drive the magnet 53 closer to or away from the weight wheel 51.

[0053] The closer magnet 53 is to counterweight wheel 51, the greater the suction force it exerts on it, causing it to generate a repulsive force against the rotation of rotor housing 41. Since rotor housing 41 is connected to sun gear 433, which is in turn driven by pedals 3 and shaft 2, this encourages the user to apply greater force to pedals 3, achieving a fitness effect. The coordinated control of touchscreen 7 and drive element 54 allows the user to quickly adjust the riding resistance according to their needs, enhancing their fitness experience and saving time and costs.

[0054] Specifically, the bicycle stand 1 includes a base frame 11 positioned on an external load-bearing surface, a first vertical frame 12 mounted on the base frame 11, and a first diagonal frame 13 mounted on the base frame 11 and tilted relative to the first vertical frame 12. The base frame 11 is arranged in an "I" shape. This "I" design enhances the base frame 11's load-bearing capacity and stability, making the spinning bike less likely to shake or tip over during use. The first vertical frame 12 is positioned perpendicular to the base frame 11. A seat cushion 131 is telescopically mounted on the first diagonal frame 13. A grip 121 is telescopically mounted on the top of the first vertical frame 12 for the user to grip. The first diagonal frame 13 is tilted relative to the first vertical frame 12, which helps distribute force during riding and improves overall stability. Furthermore, the seat cushion 131 is telescopically mounted on the first diagonal frame 13, allowing the user to adjust its height and angle according to their height and comfort level. The adjustable functions of the seat cushion 131 and grip 121 meet the individual needs of different users and enhance riding comfort.

[0055] In this embodiment, the "I"-shaped chassis 11 is composed of two first horizontal frames and a second vertical frame, and the two first horizontal frames and the second vertical frame are detachably connected by bolts, which facilitates the maintenance and transportation of the bicycle and saves unnecessary intermediate costs.

[0056] Specifically, the bicycle stand 1 has two side support plates 14 mounted on the base frame 11. Each side support plate 14 is rotatably mounted with a roller 141. The side support plates 14 extend in a direction that is angled relative to the base frame 11. This angle between the side support plates 14 and the base frame 11 helps maintain the bicycle's balance during movement, preventing accidents such as rollovers. To move the bicycle, simply press down on the handlebars 121 to bring the rollers 141 into contact with the ground to adjust the bicycle's placement. This simple and rational structure offers stable operation and minimizes costs.

[0057] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
