[0002] During physical training, knee flexion and extension movements are the core movements for lower limb strength and endurance training. The training load directly affects the training effect and exercise safety. It is necessary to collect parameters such as knee joint movement angle and movement rate in real time to quantitatively assess the training load status. Currently, the mainstream monitoring methods mostly rely on manual recording or simple wearable devices, which makes it difficult to achieve dynamic and accurate load monitoring.

Furthermore, most of them adopt a fixed strap design, making the tightness of the wearer unadjustable. They also lack real-time analysis of the rate of change of knee joint angle and dynamic load judgment functions, making it difficult to meet the needs of accurate, convenient, and adaptive monitoring during training. To solve the above problems, a smart wearable device for physical training and a method for dynamic load monitoring are proposed. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-5 This invention provides an intelligent wearable device for physical training. The device is centered on the knee joint and adopts a split leg ring structure, including two leg rings 1 and a physical fitness detector 2. The upper leg ring 1 has a larger diameter than the lower leg ring 1, which are adapted to the contours of the human thigh and calf to ensure a good fit. The two ends of the sensor 3 are connected to the inner sides of the two leg rings 1 and are electrically connected to the physical fitness detector 2. When the user bends his knee, the limb movement directly drives the sensor 3 to rotate relative to each other. The magnitude and rate of change of the angle accurately reflect the training load. Two retractable shells 4 are detachably installed on the left and right sides of the fitness detector 2 via splitting parts 5, which facilitates the storage, maintenance and replacement of the equipment; two connecting parts 6 are symmetrically installed on the left and right sides of the upper leg ring 1, one end of which is connected to the leg ring 1 and the other end is connected to the retractable shell 4, which not only achieves stable fixation of the fitness detector 2, but also reliably binds the upper leg ring 1 to the user's thigh area to prevent slippage during exercise. The winding shell 4 is provided with a winding component 7 and a fixing component 8 at the top and bottom respectively. The winding component 7 is rotatably installed inside the winding shell 4 via a bearing. The elastic band part of the connecting component 6 slides through the side wall of the winding shell 4 and is evenly wound and fixed on the winding component 7. The fixing component 8 adopts a threaded clamping structure, passes through the top of the winding shell 4 and abuts against the top of the winding component 7. The winding component 7 is locked and positioned by friction to prevent it from loosening during use. The exposed length of the elastic band 63 of the winding component 7 can be adjusted to change the binding elasticity, adapt to users with different leg circumferences, and improve wearing comfort and stability. The two ends of the cover 9 are respectively installed on the left and right sides of the lower leg ring 1 to stably fix the lower leg ring 1 to the user's lower leg. Together with the upper leg ring 1, they form a complete lower limb wearing system to ensure that the device does not shift or loosen during the monitoring process.

[0019] Specifically, refer to Figure 1 The sensing element 3 includes two support arms 31, an angle sensor 32, and a shaft 33. The two support arms 31 are fixed to the inner side of the upper and lower leg rings 1 respectively. The angle sensor 32 is installed on the outer wall of the outer support arm 31, and the shaft 33 is installed on the outer wall of the inner support arm 31. The shaft 33 can rotatably pass through the other support arm 31 and is rigidly connected to the working end of the angle sensor 32. When the knee is flexed and extended, the two support arms 31 rotate relative to each other around the shaft 33. The angle sensor 32 collects the rotation angle and angular velocity in real time and transmits them to the physical fitness detector 2 without delay.

[0020] Specifically, refer to Figure 3 The disassembly component 5 includes a fixing sleeve 51, two insert rods 52 and a spring 53. The fixing sleeve 51 is fixed to the outer wall of the physical fitness detector 2. The two insert rods 52 are symmetrically installed on the outer wall of the take-up shell 4. The insertion end is provided with a triangular guide surface. The spring 53 connects the two insert rods 52 to provide outward elastic force. During installation, the insert rods 52 automatically snap into the slots of the fixing sleeve 51. During disassembly, the insert rods 52 can be disassembled by pressing them inward. The disassembly and assembly are quick and the connection is firm.

[0021] Specifically, refer to Figure 1-2 The connector 6 includes a buckle housing 61 disposed on the side of the upper leg ring 1; a buckle block 62 with one end inserted into the buckle housing 61 and fastened to the buckle housing 61; and an elastic band 63 disposed at the other end of the buckle block 62.

[0022] Specifically, refer to Figure 4 The winding component 7 includes a rotating shaft 71, a winding shaft 72, a dial wheel 73, and a fixing plate 74. The rotating shaft 71 passes through the bottom of the winding housing 4 through a bearing. The winding shaft 72 is fixed to the top of the rotating shaft 71. An elastic band 63 is wound and fixed to the surface of the winding shaft 72. The dial wheel 73 is fixed to the bottom of the rotating shaft 71 to facilitate manual adjustment of the length by the user. The fixing plate 74 is connected to the top of the winding shaft 72 through a bearing to ensure smooth rotation without jamming.

[0023] Specifically, refer to Figure 4 The fixing component 8 includes a fixing screw 81, a stop plate 82 and two limiting rods 83. The fixing screw 81 is threaded to the top of the winding shell 4 and can be raised and lowered by rotation. The stop plate 82 is rotatably installed at the bottom end of the fixing screw 81. The limiting rods 83 slide through the stop plate 82 and are fixed inside the winding shell 4 to restrict the rotation of the stop plate 82 and ensure uniform force when pressing.

[0024] Specifically, refer to Figure 5 The covering component 9 includes two snap-fit ​​shells 91, two snap-fit ​​blocks 92, a loop buckle 93, and an elastic band 94. The snap-fit ​​shells 91 are fixed to the side of the lower leg ring 1. The snap-fit ​​blocks 92 are fastened to the snap-fit ​​shells 91. The loop buckle 93 is installed at the end of the snap-fit ​​blocks 92. The two ends of the elastic band 94 are wrapped around the loop buckle 93 to form a closed loop. The length can be adjusted by pulling the free end to adapt to different calf circumferences.

[0025] Specifically, refer to Figure 5 Both leg rings 1 have Velcro hooks 10 on their inner walls, through which sweatbands 11 are attached. The outer layer of the sweatband 11 is made of breathable non-woven fabric to ensure ventilation and heat dissipation, while the inner layer is made of water-absorbing polymer material to quickly absorb sweat and avoid dampness and discomfort from prolonged wear. The sweatband 11 is removable and replaceable to maintain hygiene.

[0026] The present invention also provides a method for dynamic load monitoring, comprising the following steps: S1: Fix the upper leg ring 1 to the thigh and the lower leg ring 1 to the calf. Adjust the length of the elastic band 1 63 and the elastic band 2 94 to make the device fit the limb. S2: Physical fitness detector 2 collects the initial angle of sensor 3 and completes zero-point calibration of the knee joint in the extended state; S3: During training, the knee bends to drive the support arm 31 and the shaft 33 to rotate. The angle sensor 32 collects the flexion and extension angle and the rate of change in real time and transmits it to the physical fitness detector 2. S4: The physical fitness detector 2 calculates and determines the low, medium and high load states based on angle and speed data and preset thresholds; S5: Continuously updates data, outputs load status in real time, and issues prompts when the load exceeds the range, enabling dynamic monitoring of training load.

[0027] Working principle This invention uses leg rings 1 with matching upper and lower diameters to fix the thigh and calf respectively, with the knee joint as the fulcrum of movement. The sensor 3 converts the flexion and extension movements of the limb into angle and rate signals to realize the quantitative monitoring of training load. When worn, the retractable part 7 can flexibly adjust the length and binding force of the elastic band 63, and the covering part 9 adapts to the circumference of the calf through the loop buckle 93. With the detachable sweatband 11, the wearing comfort and versatility are improved. During training, the knee joint bends, causing the two support arms 31 to rotate relative to each other around the axis 33. The angle sensor 32 collects angle and angular velocity data in real time and transmits them to the physical fitness detector 2. The physical fitness detector 2 filters, analyzes and calculates the data, judges the exercise intensity based on the angle change range, judges the force exertion speed based on the change rate, and generates a dynamic load curve based on the preset model to determine the load level in real time. The split component 5 enables quick assembly and disassembly of the winding shell 4 and the physical fitness detector 2. The fixing component 8 locks the winding component 7 by threaded clamping to prevent length changes during use and ensure monitoring stability. When the load exceeds the limit, the device will automatically issue an early warning to avoid injury caused by overtraining. The overall structure is compact, easy to wear, and provides accurate monitoring, realizing dynamic monitoring and safety protection of the entire process of physical fitness training load.
