[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0018] The self-generating and light-emitting exercise bike will be described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-5 As shown, a self-generating and light-emitting exercise bike includes a frame 1, a pedal drive mechanism, and a fan wheel 3. Both the pedal drive mechanism and the fan wheel 3 are rotatably mounted on the frame 1. The pedal drive mechanism drives the fan wheel 3 to rotate. The fan wheel 3 is equipped with several fan blades, generating airflow during riding. A protective net cover 2 is provided on the outside of the fan wheel 3. A light strip fixing strip 5 is located at the center of the outermost part of the protective net cover 2, and the light strip fixing strip 5 is close to the protective net cover 2. A slot 51 is provided on one side of the protective net cover 2, and a flange 21 is provided on the middle edge of the protective net cover 2. The flange 21 is engaged in the slot 51. A plurality of fixing holes are provided on the light strip fixing strip 5, and the light strip fixing strip 5 is fixed to the protective net cover 2 by screws. A light strip groove 52 is provided on the other side of the light strip fixing strip 5, and a light-emitting light strip 7 is provided in the light strip groove 52. A light-transmitting shell 4 is provided on the outside of the light-emitting light strip 7, and the light-transmitting shell 4 is engaged with the light strip fixing strip 5.

[0020] The frame 1 is made of high-strength aluminum alloy with a thickness of 2-3mm. The shape of the frame 1 can be designed according to requirements, providing structural support and stability. The pedal drive mechanism and fan wheel 3 are rotatably mounted on the frame 1 via bearings, ensuring smooth rotation with low friction. The pedal drive mechanism drives the fan wheel 3 via belt drive, with a preferred transmission ratio of 1:2 to balance resistance and speed. The fan wheel 3 has a diameter of 300-700mm and is equipped with 12-16 fan blades. The fan blades are aerodynamically designed and made of ABS plastic or aluminum alloy to efficiently generate airflow. The protective mesh cover 2 is made of wire mesh to prevent the user from contacting the rotating parts. The light strip fixing strip 5 is made of ABS plastic, and its length matches the radius of the protective mesh cover 2. The light strip fixing strip 5 covers the outer half of the protective mesh cover 2. When the user pedals the pedal 17, kinetic energy is transferred to the fan wheel 3 through the transmission system. The fan wheel 3 rotates, driving the fan blades to generate airflow. The structural design of the protective net cover 2 and the light strip fixing strip 5 is based on the modular assembly principle. The cooperation between the slot 51 and the flange 21 achieves initial positioning, and the screw fixing provides secondary tightening to ensure overall rigidity. The light strip fixing strip 5 pulls the protective net cover 2 together on both sides. The protective net cover 2 has holes at the screw installation positions, located on the flange 21, which further fixes the protective net cover 2 after the light strip fixing strip 5 pulls it together. The structure is simple but the installation is firm. The light strip 7 is powered by electrical connection. The light-transmitting shell 4 uses the principle of light refraction and scattering to make the light uniform and soft. The light strip can achieve light effects such as flowing water. This design realizes the self-illuminating function of the exercise bike, enhances the visual effect and riding fun; the protective net cover 2 improves safety and prevents pinching injuries; the wind generated by the fan wheel 3 simulates the real riding environment and enhances the exercise experience. Moreover, it does not require much modification to the original exercise bike, organically realizing the fixing function and light strip installation function of the light strip fixing strip 5, and the installed protective net cover 2 is fixed and has a beautiful light effect.

[0021] For greater ease of use and energy efficiency, a generator motor 6 is included. The generator motor 6 is fixed to the frame 1. A generator wheel 31 is located on one side of the fan wheel 3. A generator belt 61 connects the generator wheel 31 and the generator motor 6 for transmission. The output end of the generator motor 6 is electrically connected to the light strip 7. The generator motor 6 is preferably a permanent magnet synchronous generator, a commercially available motor. It is bolted to the motor mount on the frame 1. The generator wheel 31 is directly mounted on the shaft of the fan wheel 3. The generator belt 61 is a multi-wedge belt with a transmission ratio of 1:1.5 to 1:3 to match the generator speed requirements. The output end of the generator motor 6 is directly connected to the light strip 7 via a wire, with a rectifier circuit that can be installed to convert AC to DC. Based on the principle of electromagnetic induction, when the user rides and rotates the fan wheel 3, the generator wheel 31 drives the rotor of the generator motor 6 through belt transmission to cut magnetic lines of force, generating an induced electromotive force and outputting electrical energy. This electrical energy is directly supplied to the light strip 7, achieving real-time energy conversion. The self-generating design eliminates dependence on external power sources, saving energy and protecting the environment; it also increases the user's enjoyment of riding.

[0022] Another energy utilization scheme involves a control panel 13 installed on the top of the frame 1 for more intelligent and rational energy use. The control panel 13 houses a battery, and the output of the generator motor 6 is electrically connected to the battery for charging. The output of the control panel 13 is also electrically connected to the LED strip 7. The control panel 13 is mounted on the top of the front stem of the frame 1, with an ABS plastic casing and a built-in microprocessor and LCD display. The battery is a lithium-ion battery equipped with a charge / discharge management circuit. The output of the generator motor 6 is connected to the battery's charging interface via a wire, with a rectifier and voltage regulator module in between. The output of the control panel 13 is connected to the LED strip 7 via a programmable switch for dimming or timer control. The electrical energy generated by the generator motor 6 is rectified and regulated before being stored in the battery. The control panel 13 intelligently distributes energy according to riding conditions: excess energy is stored during high-intensity riding; when riding stops, the battery powers the LED strip to maintain its operation. Intelligent energy utilization extends the lifespan of the light strips and avoids energy waste; the battery acts as a buffer to ensure that the light strips can still work when riding at low speeds; the control panel 13 provides human-computer interaction, enhancing the technological feel and practicality of the device.

[0023] The detailed scheme for combining the light strip and the fixing component is as follows: The light strip groove 52 has snap-fit ​​grooves 53 on both sides of its edge; the light-transmitting housing 4 has snap-fit ​​parts 41 on both sides of its middle section; and snap-fit ​​protrusions 411 on the outer side of each snap-fit ​​part 41 that mate with the snap-fit ​​grooves 53. During installation, the snap-fit ​​protrusions 411 snap into the snap-fit ​​grooves 53. The light-transmitting housing 4 has wrapping parts 42 on both sides; after installation, the wrapping parts 42 clamp the sides of the light strip fixing strip 5, and the wrapping parts 42 are tightly fitted to the outer side walls of the light strip fixing strip 5. The snap-fit ​​grooves 53 are semi-circular grooves distributed along the entire length of the light strip groove 52. The snap-fit ​​parts 41 and the light-transmitting housing 4 are integrally injection molded, and the snap-fit ​​protrusions 411 are matching semi-circular strips. The snap-fit ​​structure is based on the principle of elastic deformation. During installation, the snap-fit ​​protrusions 411 deform under pressure and snap into the snap-fit ​​grooves 53, achieving fixation through friction. The wrapping parts 42 disperse stress through clamping action, preventing loosening. The wrapping part 42 provides a sealing effect, extending the life of the light strip; the snap-fit ​​structure is reliable and prevents it from falling off due to riding vibration.

[0024] For a better riding experience, the frame 1 is equipped with an air guide shroud 15, located outside the fan wheel 3 and on the side where the rider sits. The air guide shroud 15 has several air guide plates 151, which are rotatably connected to it. Rotating the air guide plates 151 adjusts the airflow direction of the fan wheel 3. The air guide shroud 15 is made of plastic, 2mm thick, and covers the upper half of the fan wheel 3. Preferably, the air guide shroud 15 has a frosted finish to prevent glare. Each air guide plate 151 has two windows, with multiple air guide plates 151 connected together in each window, allowing for synchronized angle adjustment. The two windows can be adjusted to different airflow angles. Based on the principle of fluid guidance, changing the angle of the air guide plates 151 adjusts the airflow outlet cross-section, thereby changing the direction and diffusion range of the wind. Users can adjust it according to their personal preferences to avoid direct airflow onto the face or body. Personalized wind field adjustment enhances comfort and reduces cycling fatigue; the 15-fold air guide concentrates airflow and improves wind efficiency.

[0025] This exercise bike allows for simultaneous hand and foot workouts. The frame 1 has hand cranks 12 on both sides, located on either side of the fan wheel 3. The middle of each hand crank 12 is rotatably connected to the frame 1, and a handlebar 121 is located at the top. A crank plate 122 is located at the bottom of each hand crank 12, with one end fixedly connected to the bottom of the hand crank 12 and the other end rotatably connected to a transmission plate 123. The foot pedal drive mechanism includes a foot pedal 17, and the other end of the transmission plate 123 is rotatably connected to the foot pedal 17. The connection point of the transmission plate 123 is offset from the rotation center of the foot pedal 17. The hand cranks 12 are made of steel tubing, and the handlebar 121 is covered with a silicone sleeve with anti-slip texture. The crank plate 122 is made of steel plate and is welded and fixed to the hand crank 12. The transmission plate 123 is a linkage structure, connected to the crank plate 122 and the foot pedal 17 via bearings at both ends. The foot pedal 17 is an injection-molded part, with the connection point offset from the center of rotation by 50-60mm, forming an eccentric mechanism. The hand-foot linkage is based on the four-bar linkage principle. When the user cranks the hand crank 12, the crank plate 122 drives the transmission plate 123, which transmits force to the eccentric point of the foot pedal 17, causing the foot pedal 17 to reciprocate. This simulates rowing or skiing movements, achieving a coordinated full-body workout. It simultaneously exercises the upper and lower limb muscle groups, improving cardiopulmonary function; the eccentric design increases the range of motion, enhancing calorie consumption; and the linkage mechanism makes the movement more coordinated and reduces monotony.

[0026] A preferred technical solution is that the pedal drive mechanism further includes a drive wheel 16, the center of which is rotatably connected to the frame 1 via a pivot. One pedal 17 is eccentrically fixed to the drive wheel 16, and another pedal 17 is located on the other side of the drive wheel 16. An extension block 124 is provided between the pedal 17 and the drive wheel 16, making the pedal 17 eccentrically positioned. A transmission plate 123 is rotatably connected to the root of the pedal 17. One pedal 17 is directly eccentrically mounted to the drive wheel 16 with an eccentricity of 50mm; the other pedal 17 achieves the same eccentricity through the extension block 124. The transmission plate 123 is connected to the root of the pedal 17 using a bearing connection. The eccentric mounting makes the movement trajectory of the pedal 17 elliptical, simulating the pedaling curve during actual riding and reducing dead spots. The extension block 124 ensures symmetrical movement of the two pedals 17, and the connection of the transmission plate 123 to the root optimizes the lever arm length and improves transmission efficiency. The cycling experience is more natural and smooth, reducing impact on the knee joint; the dual-sided balance design avoids uneven muscle exertion; the extension block is 124 adjustable to accommodate different user leg lengths.

[0027] The preferred technical solution is that the frame 1 further includes a seat cushion 11 support rod, on which a height-adjustable seat cushion 11 is mounted. An I-shaped stabilizer 14 is mounted at the bottom of the frame 1, and the bottom of the I-shaped stabilizer 14 is placed on the ground via adjustable foot pads 141. The control panel 13 is fixed to the center of the front side of the frame 1. The seat cushion 11 support rod is made of square steel tubing and is fixed via a quick-release lever. The seat cushion 11 is ergonomically designed and filled with high-density sponge. The I-shaped stabilizer 14 is welded from steel, and the bottom adjustable foot pads 141 are made of rubber, with a height adjustment range of ±10mm. The control panel 13 is fixed to the front of the frame 1 via a bracket, with a height adapted to the user's line of sight. The height adjustment mechanism is based on the principle of locking friction, accommodating users of different heights. The I-shaped frame provides low center of gravity support, and the adjustable foot pads 141 compensate for uneven ground through threaded adjustment, enhancing stability. The control panel 13 is ergonomically positioned for easy operation. Enhanced user experience, comfort, and safety; a stabilizer prevents equipment from tipping over; adjustable features increase versatility, suitable for home or gym use.
