[0001] The utility model relates to the technical field of spinning equipment, in particular to a spinning power generation device. Background Art
[0002] Traditional spinning bikes primarily rely on users adjusting pedaling speed and resistance to enhance leg muscle strength and endurance, achieving weight loss and fat burning, while also improving the user's cardiopulmonary function. Traditional spinning bikes offer advantages such as easy maintenance, ease of use, and reliable structure, effectively meeting the needs of fitness enthusiasts. However, these bikes cannot convert or capture the mechanical energy generated by exercisers during exercise, and have no functionality beyond their inherent fitness purpose.
[0003] When people noticed the loss of kinetic energy, devices that utilize kinetic energy were created. Usually, the devices convert kinetic energy into electrical energy to generate electricity, which is used to supply electricity to generate economic benefits and reduce energy consumption. Existing exercise bikes are driven by a transmission belt or a power wheel that engages with the generator shaft seat. The electricity generated is small and unstable, and cannot meet the power supply and transmission needs, resulting in poor practical performance.
[0004] To achieve the above objectives, the present invention provides a power generation device for a spinning bike, which can solve the problems raised in the above background technology.

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.
[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly used by technicians in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0033] The present invention will be described in further detail below with reference to the accompanying drawings.
[0034] One embodiment of the present invention is as follows, with particular reference to Figures 1-5 , comprising a vehicle frame 1 , a drive system 2 , and a counterweight seat 3 , wherein the vehicle frame 1 is mounted above the counterweight seat 3 ;
[0035] The driving system 2 includes a power wheel 201 and a pedal wheel 202 mounted on the frame 1. The power wheel 201 and the pedal wheel 202 are transmitted via a hinge 205. The driving system 2 also includes a driving wheel 203 mounted on the counterweight seat 3. The driving wheel 203 and the power wheel 201 are meshed with each other. The hinge 205 is a hollow card slot hinge 205. Each card slot is meshed with the power wheel 201 and the pedal wheel 202 to ensure stable power transmission. At the same time, the hollow card slot hinge 205 is easy to maintain, which is convenient for timely repair after the equipment is damaged.
[0036] A conversion module 301 is provided inside the counterweight seat 3 . The conversion module 301 includes a gear motor 210 . The gear motor 210 is meshed with the driving wheel 203 .
[0037] By setting up the drive system 2, the pedaling force of the spinning bike is converted into gear rotation force through the chain transmission between the pedal wheel 202 and the power wheel 201, and the gear meshing between the power wheel 201 and the drive wheel 203. The gear motor 210 converts the power into electricity, which is rectified by the conversion module 301 and stored for convenient use in the power supply of the lights and fans of the gym. The power supply is powered by energy conversion, saving electricity and effectively reducing operating costs.
[0038] Please refer to Figures 1-4 in particular. A gear groove 1 204 is provided on the circumference of the pedal wheel 202, and the gear groove 1 204 is engaged with the hinge 205. A gear groove 206 is provided on the circumference of the power wheel 201, and a transmission gear 1 207 is provided on one side of the power wheel 201, and the transmission gear 1 207 is engaged with the hinge 205.
[0039] Please refer to Figure 2-4. The circumferential radius of the gear groove 1 204 is three times the circumferential radius of the transmission gear 1 207. The circumferential radius of the gear groove 206 is five times the circumferential radius of the transmission gear 1 207. The circumferential radius of the gear groove 3 208 is twice the circumferential radius of the transmission gear 1 207. The circumferential radius of the transmission gear 209 is the same as that of the transmission gear 1 207. The circumferential radius of the transmission gear 1 207 is twice the circumferential radius of the gear end of the gear motor 210. By changing the radius of the gear, the amount of electricity generated by the motor is increased, and the conversion effect of the user's force is improved. The gear groove density of the transmission gear 209 and the gear force end of the gear motor 210 is high, which makes the rotation of the gear motor 210 more stable and has a certain deceleration effect.
[0040] By changing the gear radius in the drive system 2, the generated electrical energy can be much greater than the single rotational capacity of the pedal wheel 202. The generated electrical energy is sufficient to charge the battery 303 after rectification, effectively improving the electrical energy production efficiency.
[0041] In another embodiment of the present invention, please refer to Figure 2. The conversion module 301 also includes a rectifier 302 and a battery 303. The rectifier 302 is connected to the gear generator and the battery 303. The rectifier 302 rectifies the electricity generated by the gear motor 210. There are no excessive restrictions, and the rectification requirements can be met.
[0042] Please refer to Figure 1 . The frame 1 is provided with a guide groove 101, which is connected to a rotating seat 102. The interior of the guide groove 101 is rotatably connected to the rotating seat 102 via a clamping block and a bearing. The rotating seat 102 can rotate but cannot move longitudinally. A cup holder 103 is provided above the rotating seat 102. The cup holder 103 is long and strip-shaped, making it easy for the user to twist.
[0043] The internal thread at one end of the rotating seat 102 is connected to a rotating column 104, which is located inside the conducting groove 101 and one end extends out of the conducting groove 101 and is connected to a brake disc 105. The rotating column 104 is threadedly connected to the rotating seat 102. The non-friction surfaces of the brake disc 105 are located on both sides of the power wheel 201, so the brake disc 105 cannot rotate and can only move longitudinally when the cup holder 103 is twisted. The friction surface of the brake disc 105 is in contact with the power wheel 201. After using the spinning bike, the brake disc 105 can be lowered by twisting the cup holder 103 to lock the power wheel 201 to prevent the power wheel 201 from rotating and swinging and damaging the gear motor 210.
[0044] In another embodiment of the present invention, the traditional spinning bike has a limited lever arm of its power wheel, and the power and frequency generated by one end directly connected to the motor are too small to meet the charging and discharging requirements of the mains and the battery. Transformer elements are often used for voltage transformation. However, the spinning bike is close to use, and considering safety issues, the present invention is optimized by changing the lever arm between the rotating gears. The final optimization efficiency can be designed with an axle radius ratio of 30:1. The traditional single-time spinning bike generator rotates 80-110 times a minute, and the electrical frequency is only about 1.5 Hz, which does not reach the rated frequency of the mains 50 Hz. Therefore, the power generated by the traditional single-time spinning bike generator is only about 3% of the rated power of the generator. With an efficient axle radius ratio of 30:1, one rotation of the rear wheel can drive the generator rotor to rotate 30 times, which can be achieved. The electric frequency is effectively increased, thereby achieving the effect of increasing electric power. In order to achieve the maximum power generation effect of the generator, the volume of the iron wheel of the spinning bike can be reduced, thereby reducing the mass of the iron wheel to achieve the effect of reducing resistance. By adjusting the ratio of the wheel axle radius, this device can fully reach the rated frequency of 50 Hz for Chinese household circuits. Therefore, compared with the traditional single-power spinning bike generator, the power generation of this device with the same power is 50 / 1.5 times that of the traditional spinning bike generator. The coil of the traditional single-power spinning bike generator is installed in the middle of the iron wheel of the spinning bike. Its volume is small and does not reach the rated frequency, so the electric power is small. The generator of this device is installed at the bottom of the iron wheel, and the gear-shaped iron wheel drives the gear-shaped shaft at the top of the generator to rotate. In addition, a large generator can be installed, so the power generation far exceeds that of the traditional single-power spinning bike generator, which can achieve the optimization effect of power generation.
[0045] At the same time, this device can drive the rotor of a generator with a power of 20 kilowatts or more by combining manpower with reducing the mass of the iron wheel of the spinning bike. According to the principle of wheel axle rotation, the wheel radius multiplied by the power is equal to the axle radius multiplied by the resistance. Referring to the wheel axle radius ratio of 30:1, the user does not need to consume extra huge power. The power required belongs to the normal force range, which is the kinetic energy range required for normal fitness equipment, effectively improving the continuity of power generation without affecting the fitness effect of the original spinning bike.
[0046] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
