[0001] This invention relates to the field of fitness equipment technology, specifically to a stationary bike fitness device and its usage method. Background Technology

[0002] In today's health-conscious and fitness-oriented era, various fitness equipment are emerging in an endless stream. Among them, the exercise bike, as a popular aerobic exercise device, allows users to experience different cycling scenarios indoors, increasing the fun and challenge of exercise. However, most existing exercise bikes are fixed in setup and have relatively simple functions. They usually only provide fixed cycling modes and cannot realistically simulate the feeling of cycling under different road conditions, such as uphill and downhill. This limits the user's exercise effect and experience to a certain extent. Therefore, a new exercise bike fitness device is proposed. Summary of the Invention

[0014] Furthermore, the top of the limiting frame is welded to the right side of the bottom of the vehicle frame body, the bottom of the limiting frame has an opening two, the left side of the limiting frame has a hinge block one, the hinge block one is connected to the bottom left side of the vehicle frame body through a pin, and the bottom of the limiting frame has a hinge block two.

[0015] Furthermore, the hinge block 2 is externally connected to two support rods 2 via pins. The two support rods 2 have rotating rods connected to the side away from the hinge block 2 inside. A support rod 1 is provided between the two support rods 2. The inside of the support rod 1 is connected to the outer surface of the rotating rod.

The outer surface of the bidirectional threaded rod is rotatably connected to the interior of the frame body. A slide rail is welded to the inner wall of the frame body.

[0018] Furthermore, the outer surface of the bidirectional threaded rod is threaded with two wear-resistant clamping blocks. The corresponding side of the two wear-resistant clamping blocks contacts the outer ring of the flywheel. The side of the two wear-resistant clamping blocks away from the flywheel is welded with a slider. The side of the two sliders away from the wear-resistant clamping blocks is slidably connected to the inside of the slide rail.

[0019] Both wear-resistant clamping blocks have a sloping and rough surface on the side closest to the flywheel.

[0042] The resistance adjustment component 21 abuts against the support frame 111 and is used to adjust the driving strength of the frame body 113.

[0044] Vibration damping component 24 is connected to support frame 111 and is used to buffer the movement trend of the device.

[0045] A power cord 114 is connected to the right side of the support frame 111. Openings 112 are provided on the left and right sides of the top of the support frame 111. A drive device 115 is provided inside the frame body 113. The drive device 115 drives and connects to a flywheel 116. The left and right sides of the bottom of the frame body 113 pass through the openings 112 to the inside of the support frame 111.

[0046] The top of the limiting frame 231 is welded to the right side of the bottom of the frame body 113. An opening 233 is provided at the bottom of the limiting frame 231. A hinge block 232 is provided on the left side of the limiting frame 231. The interior of the hinge block 232 is connected to the left side of the bottom of the frame body 113 via a pin. A hinge block 238 is provided below the limiting frame 231. Two support rods 237 are connected to the exterior of the hinge block 238 via pins. A rotating rod 236 is connected to the interior of the two support rods 237 on the side away from the hinge block 238. A support rod 235 is provided between the two support rods 237. The interior of the support rod 235 is connected to the outer surface of the rotating rod 236. A sliding rod 234 is welded to the interior of the support rod 235 on the side away from the rotating rod 236. The support rod 235 passes through the opening 233 and extends to the limiting frame. Inside 231, the outer surface of the slide rod 234 is slidably connected to the inside of the limiting frame 231. The rotating rod 236 passes through the first support rod 235 and the two second support rods 237 and extends to the front and back. When the electric push rod 221 drives the telescopic rod 223, the telescopic rod 223 will drive the push bracket 224 to move together. When the telescopic rod 223 retracts, it drives the first support rod 235 and the second support rod 237 to unfold through the rotating rod 236. The slide rod 234 is constrained by the limiting frame 231 and pulls the frame body 113 to rotate upward around the hinge block 232, simulating uphill riding. When the telescopic rod 223 extends, it realizes the downhill scene. This design, together with the resistance adjustment of the flywheel 116, can switch between multiple riding modes, enhance entertainment and practicality, and also improve the user experience, making it easy to promote and use.

[0047] The resistance adjustment assembly 21 includes a protective cover 211. The back of the protective cover 211 is connected to the front of the frame body 113. A motor 212 is installed inside the protective cover 211. The output end of the motor 212 is connected to a bidirectional threaded rod 214 via a coupling. The bidirectional threaded rod 214 passes through the frame body 113 and extends into the interior. The outer surface of the bidirectional threaded rod 214 is rotatably connected to the interior of the frame body 113. A slide rail 213 is welded to the inner wall of the frame body 113. Two wear-resistant clamping blocks 215 are threadedly connected to the outer surface of the bidirectional threaded rod 214. One side of each wear-resistant clamping block 215 contacts the outer ring of the flywheel 116. The two wear-resistant clamping blocks 215 are located away from the flywheel 116. Slider 216 is welded to one side of the flywheel 116. The side of the two sliders 216 away from the wear-resistant clamp 215 is slidably connected to the inside of the slide rail 213. The side of the two wear-resistant clamps 215 near the flywheel 116 is beveled and rough. The motor 212 drives the bidirectional threaded rod 214 to rotate forward. The protective cover 211 is linked to the frame body 113 to provide support and optimize the appearance. The bidirectional threaded rod 214 drives the wear-resistant clamps 215 to move closer to each other along the slide rail 213, precisely fitting the outer ring of the flywheel 116. The rotational resistance is dynamically adjusted by friction to achieve personalized training intensity control, which not only ensures sports safety but also stimulates the user's potential to break through, improving training effect and sense of accomplishment.

[0048] The drive assembly 22 includes an electric push rod 221. A mounting plate 222 is installed on the right side of the electric push rod 221. A telescopic rod 223 is connected to the output end of the electric push rod 221 on the right side. The outer surface of the telescopic rod 223 is slidably connected to the inside of the mounting plate 222. A push bracket 224 is welded to the side of the telescopic rod 223 away from the electric push rod 221. The inside of the push bracket 224 away from the telescopic rod 223 is connected to the front and back of the outer surface of the rotating rod 236.

[0049] The vibration damping assembly 24 includes a support plate 241, which is disposed inside the support frame 111. The top of the support plate 241 is welded to the bottom of the first hinge block 232, the second hinge block 238, and the mounting plate 222, respectively. Damping rods 242 are installed at the four corners of the top of the support plate 241. The side of each of the four damping rods 242 away from the support plate 241 is connected to the four corners of the top of the inner wall of the support frame 111. Support legs 244 are slidably connected to the four corners inside the support plate 241. The four support legs 244 penetrate the support frame 111 and extend to the bottom. The support plate 241 is welded to the inside of the support frame 111. The bottom of each of the four support legs 244 is equipped with anti-slip rubber pads 245. When the user steps on the frame body 113, the support plate 241 moves downward, driving the support plate 241 to slide along the support legs 244. The support plate 241 moves within the support frame 111 and stretches the damping rod 242, which, together with the spring 243, forms a buffer system to effectively reduce impact, reduce noise, and improve the realism and comfort of riding. The anti-slip rubber pads 245 at the bottom of the support legs 244 further enhance friction, prevent device displacement, and improve stability and quietness.

[0050] In use, the user first adjusts the frame 113 to a suitable posture, then alternately pedals the drive device 115 to rotate the flywheel 116, simulating cycling and providing a fitness effect. During use, the support frame 111 provides support for the entire device, and the power cord 114 outside the support frame 111 provides power to the device. When the user rotates the flywheel 116 using the drive device 115 for fitness training, the rotational resistance of the flywheel 116 can be adjusted to achieve a suitable fitness intensity. Specifically, starting the motor 212 drives the bidirectional threaded rod 214 to rotate forward, and the protective cover 211, connected to the frame 113, provides support for the motor 212. The protective cover 211 also enhances the stability of the bicycle. To improve the overall aesthetics of the device, the rotation of the bidirectional threaded rod 214 causes the two wear-resistant clamping blocks 215 to move closer together. As the two wear-resistant clamping blocks 215 move closer together, the two sliders 216 slide inside the slide rail 213. The slide rail 213 is supported by the inner wall of the support frame 111, and the slide rail 213 provides a certain degree of limitation and stability for the movement trajectory of the wear-resistant clamping blocks 215 through the two sliders 216. As the two wear-resistant clamping blocks 215 move closer together, they gradually come into contact with the outer ring of the flywheel 116. At this time, the friction between the flywheel 116 and the wear-resistant clamping blocks 215 gradually increases, thereby adjusting the rotational resistance of the flywheel 116 to suit users at different stages, reduce the risk of injury to users due to training intensity, enhance the user's sense of accomplishment, and help users break through plateaus.

[0051] Simultaneously, during use, the device can simulate uphill and downhill scenarios. Specifically, the electric push rod 221 is activated, driving the telescopic rod 223 to move. At this time, the mounting plate 222, welded to the support plate 241, provides stable support for the electric push rod 221. During the movement of the telescopic rod 223, it slides inside the mounting plate 222. Simultaneously, the movement of the telescopic rod 223 drives the push bracket 224 to move as well. When the telescopic rod 223 retracts, the push bracket 224, through the action of the telescopic rod 223, drives the rotating rod 236 to move. During the movement of the rotating rod 236, it drives the first support rod 235 and the two second support rods 237 to unfold away from each other. At this time, the two second support rods 237 are connected by pins at the hinge block 2. 238 rotates at a fixed point on the outside, while support rod 235 drives slide rod 234 to move inside limit frame 231. At the same time, slide rod 234 drives frame body 113 to rotate upward through limit frame 231. At this time, left side of frame body 113 rotates at a fixed point through hinge block 232. When frame body 113 rotates upward, it will drive the user to simulate uphill riding. The resistance of flywheel 116 can be adjusted to simulate riding. Conversely, when telescopic rod 223 extends, frame body 113 will drive the user to simulate downhill riding. This provides users with a variety of riding scenarios, enhances the entertainment value of the device, improves the user experience, greatly increases the practicality of the device, and facilitates its widespread use.

[0052] Simultaneously, when the user uses the frame body 113, the support plate 241 moves downward due to the user's pedaling. At this time, the support plate 241 slides on the outer surface of multiple support legs 244. Simultaneously, the support plate 241 moves inside the support frame 111. During the sliding process of the support plate 241, multiple damping rods 242 are stretched. These damping rods 242 are stretched and store energy through the limiting effect of the inner wall of the support frame 111. Simultaneously, the movement of the damping rods 242 drives the spring 243 to move as well. At this time, the multiple damping rods 242 and the spring 243 exert pressure on the support plate 244. The movement tendency of the frame body 113 is buffered by the support plate 241, thereby reducing the movement tendency of the frame body 113, reducing the impact transmitted to the user's body, and avoiding fatigue of joints, muscles and bones. At the same time, the shock absorption system not only allows the user to experience a more realistic riding feeling, but also reduces the metallic collision sound or friction sound caused by vibration during riding, providing a quieter fitness environment. Anti-slip rubber pads 245 are installed on the bottom of multiple support legs 244, which can further reduce the noise generated by the friction between the device and the ground. At the same time, the multiple anti-slip rubber pads 245 increase the friction between the support legs 244 and the ground, reducing the movement of the device when the user pedals.

The protective cover (211) provides a certain support force to the motor (212) through its connection with the frame (113). At the same time, by setting the protective cover (211), The overall aesthetics of the device are improved. During the rotation of the bidirectional threaded rod (214), the two wear-resistant clamps (215) will move closer to each other. During the movement of the two wear-resistant clamps (215), the two sliders (216) will slide inside the slide rail (213). The slide rail (213) is supported by the inner wall of the support frame (111). The slide rail (213) provides a certain degree of limitation and stability for the movement trajectory of the wear-resistant clamps (215) through the two sliders (216). During the movement of the two wear-resistant clamps (215), they will gradually come into contact with the outer ring of the flywheel (116). At this time, the friction between the flywheel (116) and the wear-resistant clamps (215) will gradually increase, thereby adjusting the rotational resistance of the flywheel (116), adapting to users at different stages, reducing the risk of injury to users due to training intensity, enhancing the user's sense of accomplishment, and helping users break through the plateau. Step Two: Simultaneously, during use, the device can simulate uphill and downhill scenarios. Specifically, the electric push rod (221) is activated to drive the telescopic rod (223) to move. At this time, the mounting plate (222) provides stable support for the electric push rod (221) by welding it to the support plate (241). During the movement of the telescopic rod (223), it slides inside the mounting plate (222). Simultaneously, the movement of the telescopic rod (223) drives the push bracket (224) to move together. When the telescopic rod (223) retracts, the push bracket (224), through the action of the telescopic rod (223), drives the rotating rod (236) to move together. During the movement of the rotating rod (236), it drives the first support rod (235) and the two second support rods (237) to unfold away from each other. At this time, the two second support rods (237) are connected by a pin. The device rotates at a fixed point outside the hinge block 2 (238), while the support rod 1 (235) drives the slide rod (234) to move inside the limiting frame (231). At the same time, the slide rod (234) drives the frame body (113) to rotate upward through the limiting frame (231). At this time, the left side of the frame body (113) rotates at a fixed point through the hinge block 1 (232). When the frame body (113) rotates upward, the frame body (113) drives the user to simulate an uphill riding scenario. At the same time, the resistance of the flywheel (116) can be adjusted to simulate riding. Conversely, when the telescopic rod (223) extends, the frame body (113) drives the user to simulate a downhill riding scenario. This provides the user with a variety of riding scenarios, enhances the entertainment value of the device, improves the user's experience, greatly increases the practicality of the device, and facilitates its promotion and use. Step 3: Simultaneously, when the user uses the frame body (113), the frame body (113) will move downward due to the user's pedaling. At this time, the support plate (241) will slide on the outer surface of multiple support legs (244), and at the same time, the support plate (241) will move inside the support frame (111). During the sliding process of the support plate (241), multiple damping rods (242) will be stretched. At this time, the multiple damping rods (242) will be stretched and store energy through the limiting effect of the inner wall of the support frame (111). At the same time, during the movement of the damping rods (242), the springs (243) will move together. At this time, the multiple damping rods (242) and the springs (244) will move together. 43) It will buffer the movement trend of the support plate (241), thereby reducing the movement trend of the frame body (113) through the support plate (241), reducing the impact transmitted to the user's body, avoiding fatigue of joints, muscles and bones. At the same time, the shock absorption system can not only allow the user to experience a more realistic riding feeling, but also reduce the metallic collision sound or friction sound caused by vibration during riding, providing a quieter fitness environment. Anti-slip rubber pads (245) are installed at the bottom of multiple support legs (244), which can further reduce the noise generated by the friction between the device and the ground. At the same time, the friction between the support legs (244) and the ground is increased by multiple anti-slip rubber pads (245), reducing the movement of the device when the user steps.
