Description

Technical Field

[0001] This invention belongs to the field of fitness equipment, specifically a power generation and energy storage fitness device and its working method. Background Technology

[0002] Fitness equipment is divided into indoor and outdoor fitness equipment, and there are many types, such as treadmills, bench press machines, rowing machines, exercise bikes, steppers, massage chairs, strength training equipment, and fitness testing equipment. Among them, exercise bikes are a fitness activity suitable for the general public, especially women. For middle-aged and elderly people, free cycling can be used, with each session lasting 20-30 minutes, to achieve the effect of aerobic exercise. Young people can choose high-intensity cycling methods, such as interval training, to improve cardiopulmonary function and muscle strength. It can promote cardiovascular exercise, accelerate metabolism, enhance heart and lung function, and improve physical fitness. At the same time, it can also prevent high blood pressure, obesity, and arteriosclerosis, and strengthen bones. Appropriate exercise can also secrete hormones, making people cheerful and happy. When exercising on an exercise bike, the exerciser expends a lot of energy, which cannot be converted into energy for use, resulting in energy waste. There is a need for a bench press machine that can simultaneously achieve exercise and generate and store electricity. Summary of the Invention

The bottom ends of the two first connecting rods are respectively hinged to two pressure plates. The bottom end of the top groove is inclined near the side of the circular shell. A screw is rotatably installed inside the top box. The screw is threadedly connected to the movable plate. The top end of the screw is fixedly connected to the output shaft of the drive motor. The drive motor is fixedly installed at the top of the top box.

[0012] Preferably, the piston plate has bottom rods symmetrically installed at its bottom end, the bottom end of the bottom rods extending to the bottom of the bottom box, and a connecting frame fixedly installed at the bottom end of the bottom rods. A side rod is fixedly installed on one of the pressure plates away from the circular shell, one end of the side rod extending to the outside of the side box, and a push plate is fixedly installed on one end of the side rod.

[0014] Preferably, the rotational speed observation device includes a circumferential box fixedly installed on one side of the circumferential direction of the circular shell.

[0015] Preferably, an observation rod is fixedly installed on the side of the force-bearing plate away from the circular shell, one end of the observation rod extends through to the outside of the circumferential box, and scale lines are provided on the side wall of the observation rod.

[0016] A preferred method for operating a power generation and energy storage fitness device is as follows:

[0017] S1. Power generation and energy storage: During exercise, the driven wheel is rotated, and the generator generates electricity, which is then input into the battery for energy storage.

[0018] S2, Intensity Adjustment: The pressure plate is moved towards the friction plate by the drive motor, thereby adjusting the friction resistance between the friction plate and the driven wheel, thus adjusting the intensity of cycling exercise;

[0019] S3. Cooling protection: The pressure plate moves to drive the piston plate to move, controlling the amount of heat transfer fluid in the circular shell. The heat transfer fluid cools the driven wheel and heats the water at the same time, improving energy utilization.

[0020] S4. Rotational speed observation: The driven wheel rotates and continuously throws out the heat transfer fluid adhering to it, which in turn impacts the force plate and pushes the force plate to move. The rotational speed of the driven wheel is reflected by the observation rod and the scale line on it.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) In this invention, the exerciser drives the drive wheel to rotate during exercise, which in turn drives the driven wheel to rotate. One end of the shaft on the driven wheel is connected to the input shaft of the generator, thereby driving the input shaft of the generator to rotate, so that the generator generates electricity and inputs it into the battery, thus realizing the generation and storage of electricity while exercising.

[0023] (2) In this invention, friction plates are symmetrically arranged on both sides of the driven wheel. The moving plate is driven downward by the drive motor, which pushes the pressure plate toward the friction plate side, so that the first spring is compressed. The friction between the friction plate and the driven wheel is adjusted by adjusting the elastic force of the first spring, thereby adjusting the exercise intensity.

[0024] (3) In this invention, the bottom box and the bottom of the inner cavity of the circular shell are filled with heat-conducting liquid. When the driven wheel rotates continuously, the heat-conducting liquid continuously contacts the driven wheel, thereby cooling and protecting the driven wheel. At the same time, the heat in the heat-conducting liquid is transferred to the water flowing through the capillary water tank to heat the water and improve the energy utilization conversion rate.

[0025] (4) In this invention, when the pressure plate moves toward the friction plate side, the push plate moves along with it, and then pushes the connecting frame and piston plate upward through the second connecting rod, so that part of the heat-conducting liquid in the bottom box is injected into the circular shell, so that the friction between the friction plate and the driven wheel is greater, the contact area between the driven wheel and the heat-conducting liquid is larger, and the cooling protection effect of the driven wheel can be adaptively adjusted.

[0026] (5) In this invention, as the driven wheel rotates, some of the heat-conducting liquid adheres to the surface of the driven wheel and is thrown out under the action of the centrifugal force of the driven wheel rotation, and some of it is thrown out onto the force plate. The greater the centrifugal force of the driven wheel rotation, the greater the impact force of the heat-conducting liquid on the force plate, which makes the observation rod move outward a greater distance. The speed of the driven wheel can be reflected by the scale line on the observation rod, which makes it convenient to observe the exercise state. Attached Figure Description

A rotating shaft 304 is coaxially mounted on the driven wheel 303. The rotating shaft 304 is connected to the drive wheel 2 via a chain and sprocket transmission. One end of the rotating shaft 304 is fixedly connected to the input shaft of the generator 305. The generator 305 is installed inside the mounting box 302, which is fixedly mounted on one side of the circular shell 301. The generator 305 is electrically connected to a storage battery. When the exerciser exercises, the drive wheel 2 is driven to rotate, which in turn drives the driven wheel 303 to rotate. One end of the rotating shaft 304 on the driven wheel 303 is connected to the input shaft of the generator 305, thereby driving the input shaft of the generator 305 to rotate, so that the generator 305 generates electricity and inputs it into the storage battery, realizing power generation and storage while exercising.

[0041] The top of the circular shell 301 is provided with a strength adjustment component 306, the bottom of the circular shell 301 is provided with a cooling protection component 307, and one side of the circular shell 301 is provided with a rotation speed observation component 308.

[0042] The strength adjustment component 306 includes side boxes 3061 symmetrically installed on both sides of the top of the circular shell 301. A pressure plate 3062 is provided inside the side box 3061. Two friction plates 3063 are provided inside the circular shell 301, symmetrically arranged on both sides of the driven wheel 303. The pressure plate 3062 corresponds one-to-one with the friction plate 3063. A first spring 3066 is symmetrically installed between the pressure plate 3062 and the friction plate 3063. Guide rods are symmetrically installed on the side of the friction plate 3063 closest to the pressure plate 3062. 3064, pressure plate 3062 is slidably connected to guide rod 3064, end plate 3065 is fixedly installed at the end of guide rod 3064, end plate 3065 is located on the side of pressure plate 3062 away from friction plate 3063, top box 3068 is fixedly installed at the top of circular shell 301, side grooves 3069 are symmetrically opened on both sides of top box 3068, top groove 3067 is opened at the top of side box 3061, movable plate 30610 is slidably installed inside top box 3068, and movable plate 30610 is slidably installed on both sides of movable plate 30610. Side plates 30611 are symmetrically installed on both sides, located above side boxes 3061. First connecting rods 30612 are hinged to the ends of the side plates 30611. The bottom ends of the two first connecting rods 30612 are respectively hinged to two pressure plates 3062. The bottom end of the top groove 3067 is inclined near the circular shell 301. A screw 30613 is rotatably installed inside the top box 3068. The screw 30613 is threadedly connected to the movable plate 30610, and the top end of the screw 30613 is connected to the drive motor 3061. The output shaft of 4 is fixedly connected, and the drive motor 30614 is fixedly installed on the top of the top box 3068. Friction plates 3063 are symmetrically arranged on both sides of the driven wheel 303. The drive motor 30614 drives the movable plate 30610 to move downward, pushing the pressure plate 3062 to move towards the friction plate 3063, so that the first spring 3066 is compressed. The friction between the friction plate 3063 and the driven wheel 303 is adjusted by adjusting the elasticity of the first spring 3066, thereby adjusting the exercise intensity.

[0043] The cooling protection component 307 includes a bottom box 3071 fixedly installed at the bottom end of a circular shell 301. A connecting groove 3072 is provided at the top of the bottom box 3071, extending to the bottom of the inner cavity of the circular shell 301. A piston plate 3073 is movably installed inside the bottom box 3071. The interior of the bottom box 3071 and the bottom of the inner cavity of the circular shell 301 are filled with heat-conducting fluid. Capillary water channels 3079 are equidistantly provided inside the bottom shell of the circular shell 301, with symmetrically installed capillary water channels 3079 at both ends. Side branch pipe 30710, side main pipe 30711 is provided on both sides of the circular shell 301, the side main pipe 30711 is connected to multiple side branch pipes 30710 on the same side, the bottom box 3071 and the bottom of the inner cavity of the circular shell 301 are filled with heat-conducting liquid. When the driven wheel 303 rotates continuously, the heat-conducting liquid continuously contacts the driven wheel 303, thereby cooling and protecting the driven wheel 303. At the same time, the heat in the heat-conducting liquid is transferred to the water flowing through the capillary water tank 3079 to heat the water and improve the energy utilization conversion rate.

[0044] A bottom rod 3074 is symmetrically mounted on the bottom end of the piston plate 3073. The bottom end of the bottom rod 3074 extends to the bottom of the bottom box 3071. A connecting bracket 3075 is fixedly mounted on the bottom end of the bottom rod 3074. A side rod 3078 is fixedly mounted on the side of one of the pressure plates 3062 away from the circular shell 301. One end of the side rod 3078 extends to the outside of the side box 3061. A push plate 3076 is fixedly mounted on the other end of the side rod 3078. The connecting bracket 3075 is located on the side of the push plate 3076 closer to the circular shell 301. A second connecting rod 3077 is hinged to the bottom end of the push plate 3076. One end is hinged to the top of the connecting frame 3075. The second connecting rod 3077 is inclined upward near the end of the circular shell 301. When the pressure plate 3062 moves toward the friction plate 3063, the push plate 3076 moves accordingly. Then, through the second connecting rod 3077, the connecting frame 3075 and the piston plate 3073 are pushed upward, so that part of the heat-conducting liquid in the bottom box 3071 is injected into the circular shell 301. This makes the friction between the friction plate 3063 and the driven wheel 303 greater, and the contact area between the driven wheel 303 and the heat-conducting liquid larger, so that the cooling protection effect of the driven wheel 303 can be adaptively adjusted.

[0045] The rotational speed observation element 308 includes a circumferential box 3081 fixedly installed on one circumferential side of a circular shell 301. The inner cavity of the circumferential box 3081 is connected to the inner cavity of the circular shell 301. A force-bearing plate 3082 is movably installed inside the circumferential box 3081. A second spring 3084 is symmetrically installed on the side of the force-bearing plate 3082 away from the circular shell 301. One end of the second spring 3084 is fixedly connected to the inner wall of the end of the circumferential box 3081 away from the circular shell 301. An observation rod 3083 is fixedly installed on the side of the force-bearing plate 3082 away from the circular shell 301. One end of the rod 3 extends to the outside of the circumferential box 3081. Scale lines are provided on the side wall of the observation rod 3083. When the driven wheel 303 rotates, some of the heat-conducting liquid adheres to the surface of the driven wheel 303 and is thrown out by the centrifugal force of the driven wheel 303. Some of the liquid is thrown onto the force plate 3082. The greater the centrifugal force of the driven wheel 303, the greater the impact force of the heat-conducting liquid on the force plate 3082, resulting in a greater outward movement distance of the observation rod 3083. The scale lines on the observation rod 3083 can reflect the rotational speed of the driven wheel 303, facilitating the observation of the exercise status.

[0046] Working principle: When in use, the exerciser sits on the frame 1 and drives the drive wheel 2 to rotate as if riding a bicycle. The drive wheel 2 and the shaft 304 drive the driven wheel 303 to rotate through the sprocket and chain.

[0047] Since one end of the rotating shaft 304 is connected to the input shaft of the generator 305, the driven wheel 303 rotates, driving the input shaft of the generator 305 to rotate, thereby generating electricity and storing the generated electrical energy in the battery.

[0048] If cycling feels too easy and doesn't provide the desired workout effect during exercise, the drive motor 30614 is activated, driving the screw 30613 to rotate. Since the screw 30613 is threadedly connected to the movable plate 30610, it causes the movable plate 30610 to move downwards. Then, through the first connecting rod 30612, the pressure plate 3062 is pushed towards the friction plate 3063. The friction plate 3063 contacts the side wall of the driven wheel 303, causing the pressure plate 3062 to move towards the friction plate 3063, which compresses the first spring 3066. This increases the frictional resistance between the friction plate 3063 and the driven wheel 303, damping the rotation of the driven wheel 303 and increasing the workout effect. The frictional resistance can be adjusted by changing the distance between the pressure plate 3062 and the friction plate 3063. The drive motor 30614 is powered by a stored-energy battery.

[0049] As the driven wheel 303 rotates continuously, heat is generated by friction between the driven wheel 303 and the friction plate 3063. Since the bottom cavity of the bottom box 3071 and the bottom of the circular shell 301 are filled with heat-conducting liquid, the heat generated is transferred to the heat-conducting liquid at the bottom of the circular shell 301 during the rotation of the driven wheel 303, thereby cooling the driven wheel 303 and improving its service life. At the same time, the water that needs to be heated is introduced from the side main pipe 30711 on one side and discharged from the side main pipe 30711 on the other side. When the water passes through the capillary water channel 3079, the heat in the heat-conducting liquid is transferred to the water flowing through the capillary water channel 3079, thereby heating the water and improving energy utilization.

[0050] When the pressure plate 3062 moves toward the friction plate 3063, it drives the push plate 3076 to move toward the circular shell 301. Then, through the second connecting rod 3077, it pushes the connecting frame 3075 and the piston plate 3073 to move upward, so that the heat-conducting liquid inside the bottom box 3071 is injected into the circular shell 301. This makes the friction between the friction plate 3063 and the driven wheel 303 greater, and the contact area between the driven wheel 303 and the heat-conducting liquid larger, so that the cooling protection effect of the driven wheel 303 can be adaptively adjusted.

[0051] Simultaneously, as the driven wheel 303 rotates, some of the heat-conducting fluid adheres to the surface of the driven wheel 303. With the rotation of the driven wheel 303, the centrifugal force generated by the rotation of the driven wheel 303 throws the heat-conducting fluid outward. The faster the driven wheel 303 rotates, the greater the centrifugal force on the heat-conducting fluid. Some of the heat-conducting fluid is thrown towards the force plate 3082 and impacts the surface of the force plate 3082, thereby pushing the force plate 3082 to move away from the circular shell 301. This causes the observation rod 3083 to move outward. The impact force on the force plate 3082 can be observed through the scale lines on the observation rod 3083, thus reflecting the rotational speed of the driven wheel 303 and facilitating the observation of the exercise status.
