Description

Technical Field

[0001] This application relates to the field of sports training equipment and technology, and in particular to sports data acquisition devices. Background Technology

[0002] In competitive cycling, athletes need to adapt to various complex road conditions, especially uphill and downhill sections with different gradients. Uphill sections require greater power output and pedaling force to overcome gravity, while downhill sections may involve higher speeds and control skills.

[0003] To improve training efficiency, accurately assess athlete performance, and develop scientific training plans, it is crucial to precisely simulate these road conditions and collect key motion data in an indoor training environment.

[0004] Currently, ordinary bicycle training platforms are fixed to the rear wheel or frame using a specific device. Their main drawback is that the platform itself is completely horizontal and cannot simulate any slope changes, which greatly limits the realism of the training and the targeted training effect on specific muscle groups. The data of athletes on fixed training platforms cannot accurately reflect their performance on actual slopes.

[0005] In other words, existing technologies have the following technical problems: ordinary bicycle motion data acquisition devices are unable to accurately collect slope motion data. Therefore, a motion data acquisition device is proposed to address the above problems. Summary of the Invention

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] Please see Figure 1-6 As shown, a motion data acquisition device includes:

[0034] A bicycle motion component 1, which includes a fixed housing 101, pedals 106 and a flywheel 107;

[0035] A tilt adjustment component 2 is provided at the bottom of the bicycle motion component 1 and is connected and supported to the bicycle motion component 1. The tilt adjustment component 2 can adjust the tilt angle of the bicycle motion component 1.

[0036] The resistance adjustment component 3 is disposed inside the fixed housing 101. The resistance adjustment component 3 includes a friction block 309 and a self-adjusting component. The self-adjusting component is used to automatically increase or decrease the friction damping when the bicycle motion component 1 is tilted.

[0037] Through the above technical solution, the tilt adjustment component 2 can flexibly simulate the motion state when going uphill or downhill. At the same time, the resistance adjustment component 3 is set up so that the damping value can be automatically adjusted when simulating going uphill or downhill, which plays a simulation function. This allows for more accurate data collection, making it particularly suitable for cyclists.

[0038] The outer surface of the fixed housing 101 is fixedly connected to the support seat 102 and the gripping component 103.

[0039] A rotating shaft 105 is rotatably connected to the inner cavity of the fixed housing 101. A flywheel 107 is fixedly connected to the arc-shaped wall of the rotating shaft 105. Pedals 106 are fixedly connected to both ends of the rotating shaft 105. With this technical solution, when the athlete collects data, he drives the flywheel 107 to rotate by stepping on the pedals 106, thereby realizing the cycling exercise.

[0040] The fixed housing 101 is also equipped with a motion data acquisition module. Preferably, the motion data acquisition module includes a speed sensor 108. By setting the speed sensor 108, motion data can be collected when the flywheel 107 is rotating.

[0041] Preferably, the motion data acquisition module further includes a microcontroller, which is electrically connected to the speed sensor 108 and is used to process the acquired motion data and wirelessly transmit the data to external devices to facilitate real-time monitoring of cycling parameters by cyclists.

[0042] Specifically, the speed sensor 108 is a Hall sensor or photoelectric encoder, arranged near the flywheel 107 to detect the rotational speed of the flywheel 107. Furthermore, the motion data acquisition module also includes an angle sensor fixed to the fixed housing 101, used to measure the tilt angle of the fixed housing 101 in real time, and combining the angle data with the speed data to generate a simulated uphill or downhill motion report. For example, the angle sensor has an accuracy of ±0.5 degrees and a sampling frequency of 100Hz.

[0043] The tilt adjustment assembly 2 includes a fixed base 201, a support frame 202, a connecting frame 203, a movable leg 204, and a support rod 205. The support frame 202 is fixedly connected to one side of the upper surface of the fixed base 201, and the connecting frame 203 is rotatably connected to the upper end of the support frame 202. The upper end of the connecting frame 203 is fixedly connected to the bottom surface of the fixed housing 101.

[0044] The fixed base 201 has an internal cavity, and a movable slider 209 is slidably connected in the internal cavity. A movable leg 204 is slidably connected to the upper surface of the fixed base 201. The movable leg 204 is fixedly connected to the movable slider 209. One end of a support rod 205 is rotatably connected to the movable leg 204. A fixed leg 206 is rotatably connected to the other end of the support rod 205. The fixed leg 206 is fixedly connected to the bottom surface of the fixed housing 101.

[0045] A servo motor 208 is fixedly installed in the inner cavity of the fixed base 201. One end of a drive screw 207 is fixedly connected to the end of the output shaft of the servo motor 208. The other end of the drive screw 207 is rotatably connected to the inner cavity side wall of the fixed base 201. The drive screw 207 passes through the movable slider 209 and is threadedly engaged with the movable slider 209. With this technical solution, when it is necessary to adjust the tilt posture of the fixed housing 101 to simulate going up or down a slope, the servo motor 208 can drive the drive screw 207 to rotate, thereby driving the movable slider 209 to move. The movement of the movable slider 209 drives the movable stand 204 to move, thereby pushing the support rod 205 to rotate at an angle, thereby driving the fixed housing 101 to tilt, thus realizing the function of simulating going up or down a slope.

[0046] Preferably, the servo motor 208 includes an encoder, which is coaxially mounted with the servo motor 208 to provide real-time feedback on the position of the moving slider 209, ensuring precise control of the tilt angle and preventing overshoot or loss of control risks.

[0047] Specifically, the maximum tilt angle range of the tilt adjustment component 2 is -15 degrees to +15 degrees, and the pitch of the drive screw 207 is 5 mm, so that for every revolution of the servo motor 208, the moving slider 209 moves 5 mm, thereby realizing step-by-step angle adjustment; furthermore, the upper surface of the fixed base 201 is provided with a slide rail, and the moving foot 204 is slidably connected through the slide rail. The slide rail is made of hardened steel to reduce friction and wear.

[0048] The friction block 309 has an arc-shaped groove on its side wall that matches the arc surface of the flywheel 107. The friction block 309 has a sliding groove, and a limiting guide rod 310 is slidably disposed in the sliding groove of the friction block 309. The limiting guide rod 310 is fixedly connected to the inner cavity wall of the fixed housing 101. The friction block 309 contacts the flywheel 107 to provide frictional damping.

[0049] The self-adjusting component includes a fixed shaft 301, a swing arm 302, a counterweight 303, a connecting rod 304, a rotating shaft 305, a lever 306, and a connecting sleeve 307. The fixed shaft 301 is fixedly installed in the inner cavity of the fixed housing 101. The rotating shaft 305 is rotatably connected to the fixed housing 101. The bottom end of the rotating shaft 305 is rotatably connected to the lever 306. The connecting sleeve 307 is slidably connected in the inner cavity of the lever 306. One end of the connecting sleeve 307 is fixedly connected to a friction block 309. One end of a spring 311 is fixedly connected to the other end of the connecting sleeve 307. The other end of the spring 311 is fixedly connected to the inner wall of the lever 306.

[0050] A fixed shaft 301 is fixedly connected to the inner cavity of the fixed housing 101. A swing arm 302 is rotatably connected to the fixed shaft 301. A counterweight 303 is fixedly connected to the bottom end of the swing arm 302. One end of a connecting rod 304 is rotatably connected to the side wall of the swing arm 302. The other end of the connecting rod 304 is rotatably connected to the top end of the lever 306. Through this technical solution, when the bicycle motion component 1 tilts, the counterweight 303 can be automatically deflected by gravity, thereby causing the swing arm 302 to rotate at an angle. The rotation of the swing arm 302 drives the connecting rod 304 to move, thereby pushing the lever 306 to rotate, which in turn drives the connecting sleeve rod 307 to move, causing the spring 311 to compress and increasing the pressure of the friction block 309 on the flywheel 107, thus realizing the function of automatically increasing damping. Conversely, when simulating a downhill slope, the damping automatically decreases, realizing dynamic resistance simulation.

[0051] Preferably, the friction block 309 is made of nitrile rubber or polyurethane with a friction coefficient of 0.3-0.6. The surface of the arc groove is provided with a wear-resistant coating to extend its service life and ensure stable frictional contact with the flywheel 107.

[0052] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
