[0002] With the enhancement of people's health awareness, the combination of fitness and green energy has become a trend. In traditional fitness equipment, training load is usually provided by counterweights or external power systems, which not only occupy space but also limit the diversity and flexibility of the fitness process. At the same time, the existing fitness equipment on the market lacks energy recovery function and cannot generate reusable energy during exercise.

[0003] The power system of existing fitness equipment or vehicles is mostly a single mechanical structure, which fails to effectively combine the dual functions of fitness and energy recovery, or has low efficiency. Especially in traditional exercise bikes, although sufficient exercise load can be provided, there is a lack of mechanism to adjust the training intensity, and human movement cannot be effectively converted into usable electrical energy to supply external devices. With the rapid development of fitness and green energy technology, the market demand for more efficient, environmentally friendly multifunctional fitness equipment is increasing. SUMMARY

[0004] To solve at least one of the above problems, the present application proposes a multi-gear adjustable fitness power generation vehicle wheel and its transmission system that can adjust the intensity of fitness, power generation and speed. Through this system, users can control the intensity of fitness by adjusting the speed, while generating electrical energy during exercise, realizing the recovery and utilization of green energy.

[0035] In a preferred embodiment, please refer to Figure 4 , Figure 5 As shown, the transmission device 2 includes a transmission belt 21 and transmission pins 22. The transmission belt 21 is a power transmission component that transmits power generated by an external foot pedal or hand crank to achieve the purpose of fitness training and motion power generation. Multiple transmission pins 22 are disposed inside the transmission belt 21 and are rotatably connected to it. Each transmission pin 22 includes a shank 221, transmission teeth 222, a retaining ring 223, a moving tooth 224, and a spring pin 2231. The spring pin 2231 is disposed on the retaining ring 223 and can spring up and down under pressure, serving a locking function. The retaining ring 223 is cylindrical and has at least one of the transmission pins 222 and 2231. A spring pin 2231 is provided; a moving tooth 224 is fixedly provided at one end of the retaining ring 223, the length of the moving tooth 224 is less than or equal to the thickness of the toothed disc 13, and the moving tooth 224 is rotatably connected to the tooth 132; a transmission tooth 222 is fixedly provided at the other end of the retaining ring 223, the length of the transmission tooth 222 is equal to the width of the transmission belt 21, and the transmission tooth 222 is rotatably connected to the transmission belt 21; a pin shank 221 is provided at the center end of the transmission tooth 222, the shape and structure of the pin shank 221 are not limited in this invention, and its function is to push or pull out the transmission pin 22 to make the moving tooth 224 move or disengage from the tooth 132.

[0036] In another preferred embodiment, the transmission belt 21 is a transmission chain or other transmission medium that can be matched for transmission.

[0037] In a preferred embodiment, such as Figure 4 As shown, the power generation device 3 includes a generator 31 and a cylindrical rotor 32; the generator 31 is a cylindrical hollow motor, that is, the center of the cylinder of the generator 31 is a hollow through structure, and the cylindrical rotor 32 is provided on one side edge of the hollow structure, that is, the interior of the cylindrical rotor 32 is also a hollow structure, and it is through the same diameter as the hollow structure of the cylinder of the generator 31; an internal concave gear is provided on the cylindrical rotor 32, and the internal concave gear is rotatably connected to the transmission belt 21 to drive the generator 31 to operate and generate electricity.

[0038] In a preferred embodiment, the frame 4 includes a shaft roller 41, a clamping plate 42, a support rod 43, and a pin box 44; the shaft roller 41 is disposed through the hollow structure of the generator 31 and the cylindrical rotor 32; both ends of the shaft roller 41 extend beyond the generator 3 and are used to connect the support rod 43.

[0039] In a preferred embodiment, the clamping plate 42 is a rectangular vertical plate with a certain thickness, disposed on the outer side of the front panel 11 and fixedly connected to the front panel 11. Multiple circular holes are provided on the vertical panel of the clamping plate 42, the diameter of which is slightly larger than the diameter of the transmission pin 22. The number of these holes is the same as the number of holes on the front panel 11. These holes are coaxially designed corresponding to the transmission pin 22. At least one working locking hole is provided on the inner side of each hole, the diameter of which is slightly larger than that of the spring pin 2231. It is understood that when the pin handle 221 is manually pushed or pulled, the transmission pin 22 will move inward or outward. When the spring pin 2231 moves inward to the working locking hole, it will spring into the working locking hole, lock and fix it, and cause the transmission pin 22 to rotate.

[0040] In a preferred embodiment, the pin box 44 is disposed on the outside of the transmission belt 21. The pin box 44 is a rectangular box, and its body is provided with a locking hole on the push-pull trajectory of the spring pin 2231 for fixing the spring pin 2231. When the spring pin 2231 moves outward to the locking hole, it will spring into the locking hole and lock in place. Support rods are provided at both ends of the rear plate of the box body, and the support rods are fixedly connected to the card plate 42. The function of the pin box 44 is to store the transmission pin 22 when it is not in operation.

[0041] In a preferred embodiment, the multi-level adjustable fitness power generation wheel and its transmission system of the present invention can adjust the wheel speed and kinetic energy in multiple levels, thereby adjusting the fitness intensity or driving speed or affecting the power generation; specifically, the above-mentioned adjustment purpose can be achieved by adjusting the working state of one or more of the transmission pins 22 of the present invention. For example, when a transmission pin 22 close to the center of the gear 13 is pushed from the storage locking hole of the pin box 44 to the working locking hole of the clamping plate 42, the rotation speed or movement of the wheel 1 is slow due to the small actuation radius of the gear 13. In this state, the exercise intensity is relatively high, and a lot of force is required to pedal or crank it. Conversely, when a transmission pin 22 far from the center of the gear 13 is pushed from the storage locking hole of the pin box 44 to the working locking hole of the clamping plate 42, the rotation speed or movement of the wheel 1 is faster due to the large actuation radius of the gear 13. In this state, the exercise intensity is relatively low, and pedaling or cranking it is relatively easy, requiring no extra force. The power generation in these two states is also completely different, that is, the faster the rotation speed, the better the power generation effect, and vice versa.

[0042] In a preferred embodiment, when all the transmission pins 22 are pushed from the storage locking hole of the pin box 44 to the working locking hole of the card plate 42, the wheel body 1 rotates at its fastest speed or travels at its fastest speed, and the resistance is relatively minimal. In this state, the fitness intensity is moderate, the foot pedal or hand crank is easy and effortless, and the power generation effect is optimal.

[0043] The electricity generated by this invention is green, low-carbon, and environmentally friendly. The generated energy can be immediately used for lighting, intelligent displays, navigation, and music playback on vehicles or fitness equipment, or transmitted externally via an interface. It can also be stored in an external battery for backup via a line connection. This invention can be widely applied to bicycles, electric vehicles, and fitness equipment, achieving the dual functions of fitness training and energy recovery while ensuring smooth movement. It has the advantages of compact structure, flexible adjustment, and wide applicability.

For those skilled in the art, any equivalent modifications and substitutions to this invention are also within the scope of the present invention. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of the present invention should be covered within the scope of the present invention.
