AI Technical Summary
[0003]在引体向上训练过程中,学员常常因发力模式错误,如过度依赖肩部力量、肌肉紧张或本体感觉失调等问题,导致肩部锁死等异常情况,影响训练效果且可能造成运动损伤
[0018]This invention employs an anti-movement mechanism. First, a muscle electromyography (EMG) sensor is installed on the trainee's shoulder. Then, a joint angle sensor is installed at the trainee's joint. A vibration ring is then placed on the trainee's wrist. The trainee then presses their leg against a flexible contact plate. When the flexible contact plate is pressed, it pushes a pusher frame backward. When the pusher frame is pushed, it pushes a compression plate backward. When the compression plate is pushed, it expands in a direction away from each other. As the compression plate expands, it pushes an extension ring to expand in a semi-circular direction away from each other, thus securing the trainee's leg. Finally, the trainee grasps the surface of the pressure sensor. When starting a pull-up, the student's upward movement causes the collar to move upward, which in turn moves the connecting column upward. This movement of the connecting column causes the lifting slider to slide upward along the inner wall of the limiting groove. As the lifting slider slides, it compresses the limiting telescopic rod, causing it to contract. This prevents the student's legs from moving erratically and resulting in incorrect form. During the pull-up, a muscle electromyography (EMG) sensor detects the electrical activity signals of the muscles. By analyzing these signals, the sequence and intensity of muscle contraction can be determined, thus monitoring whether the student is initiating the pull-up according to the correct movement pattern.

Description
Technical Field
[0001] This invention relates to the field of sports training auxiliary equipment technology, specifically a pull-up training auxiliary error correction device. Background Technology
[0002] Pull-ups are one of the optional events in the physical education entrance examinations for junior high and high school students. They primarily test the development level of upper limb muscle strength and are a key assessment item for male upper limb strength. It is a suspension strength exercise that involves using one's own strength to overcome one's own weight. It is the most basic method for strengthening the back and is also one of the important reference standards and items for measuring male physical fitness.
[0003] During pull-up training, trainees often experience shoulder lock-up and other abnormalities due to incorrect force application patterns, such as over-reliance on shoulder strength, muscle tension, or proprioceptive dysfunction. This affects training effectiveness and may cause sports injuries. Most existing training equipment cannot effectively monitor and correct these incorrect force application patterns. Therefore, a device is needed that can monitor and assist trainees in correctly completing pull-ups in real time. Summary of the Invention

[0014] Furthermore, the surface of the connecting column is fixedly connected to the bottom of the elastic frame, the end of the limiting elastic rod away from the sliding frame is fixedly connected to the surface of the right-angle plate, the end of the pulling plate away from the right-angle plate is rotatably connected to the top of the telescopic plate, and both ends of the sliding plate are fixedly connected to the top of the support frame.
[0015] Furthermore, the correction mechanism includes a fixed plate, a reset elastic rod is fixedly connected to the surface of the fixed plate, a right-angle frame is fixedly connected to the end of the reset elastic rod away from the fixed plate, a U-shaped plate is fixedly connected to the surface of the right-angle frame, and a vertical rod is fixedly connected to the surface of the U-shaped plate.
[0016] Furthermore, the end of the U-shaped plate away from the right-angle frame is fixedly connected to the surface of the driven frame, both ends of the elastic plate are fixedly connected to the ends of the uprights, and the end of the fixed plate away from the reset elastic rod is fixedly connected to the surface of the slide plate.
[0017] The present invention has the following beneficial effects:
[0018] This invention employs an anti-movement mechanism. First, a muscle electromyography (EMG) sensor is installed on the trainee's shoulder. Then, a joint angle sensor is installed at the trainee's joint. A vibration ring is then placed on the trainee's wrist. The trainee then presses their leg against a flexible contact plate. When the flexible contact plate is pressed, it pushes a pusher frame backward. When the pusher frame is pushed, it pushes a compression plate backward. When the compression plate is pushed, it expands in a direction away from each other. As the compression plate expands, it pushes an extension ring to expand in a semi-circular direction away from each other, thus securing the trainee's leg. Finally, the trainee grasps the surface of the pressure sensor. When starting a pull-up, the student's upward movement causes the collar to move upward, which in turn moves the connecting column upward. This movement of the connecting column causes the lifting slider to slide upward along the inner wall of the limiting groove. As the lifting slider slides, it compresses the limiting telescopic rod, causing it to contract. This prevents the student's legs from moving erratically and resulting in incorrect form. During the pull-up, a muscle electromyography (EMG) sensor detects the electrical activity signals of the muscles. By analyzing these signals, the sequence and intensity of muscle contraction can be determined, thus monitoring whether the student is initiating the pull-up according to the correct movement pattern.
[0019] This invention employs a lumbar support mechanism. When the connecting column moves upward, it compresses the elastic frame. This compression causes the middle section of the elastic frame to bend. This bending pushes the driven frame towards itself. As the driven frame moves, it causes the sliding frame to slide along the inner wall of the slide plate towards itself. This sliding motion further drives the driven rod towards itself, which in turn pushes the push plate towards itself. The push plate's movement then propels the telescopic plate forward to fit against the trainee's waist. The telescopic plate's movement, through the pulling force of the pull plate, causes its ends to retract. When the telescopic plate retracts, it causes the cushioning elastic rods to move closer together. As the cushioning elastic rods move, they push the contact rubber pads to move closer together and fit against the sides of the trainee's waist. This helps prevent lower back sprains in case the trainee makes a dangerous mistake while doing pull-ups. During pull-ups, the joint angle sensor measures the angle changes of the shoulder joint in real time. Combined with muscle electrical signals, it determines whether the shoulder movement is within the normal range. When the angle change is abnormal and the muscle contraction pattern is incorrect, it can be determined that the force application method is incorrect, such as the shoulder locking too early, causing the angle change to not conform to the normal pull-up trajectory.
[0020] This invention employs a correction mechanism. When the driven frame moves, it causes the U-shaped plate to move closer to each other. The movement of the U-shaped plate pushes the right-angle frame closer to each other, and the movement of the right-angle frame pulls the return elastic rod to extend closer together. Simultaneously, the movement of the U-shaped plate causes the upright to move closer together, compressing the elastic plate. When the elastic plate is compressed, its middle section bends, pushing the correction rod downwards. This downward movement of the correction rod brings it into contact with the student's shoulders, effectively detecting whether the student's shoulders remain level during pull-ups. Pressure sensors detect the student's grip strength and distribution on the bar during pull-ups. Different grip strength patterns can reflect the student's force application tendency to some extent, aiding in determining whether the force application is correct. Furthermore, a vibration ring can be used to alert the student to adjust their force application method when the microprocessor determines that the student's force application is incorrect, such as premature or excessive contraction of the shoulder muscles. The intensity and frequency of the vibration can be adjusted according to the severity of the error so that trainees can clearly perceive the prompts.

[0035] 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.
[0036] Please see Figure 1 - Figure 10 As shown, the present invention is a pull-up training auxiliary error correction device, including a monitor 1, a muscle electromyography (EMG) sensor 2 fixedly connected to the top of the monitor 1, a joint angle sensor 3 fixedly connected to the top of the monitor 1, a pressure sensor 4 fixedly connected to the surface of the monitor 1, and a vibration ring 5 fixedly connected to the surface of the monitor 1. First, the EMG sensor 2 is installed on the student's shoulder, then the joint angle sensor 3 is installed at the student's joint, and then the vibration ring 5 is put on the student's wrist.
[0037] Anti-movement mechanism 10 includes a pressing plate 18, and a pusher 19 is rotatably connected to the end of the pressing plate 18. When the pusher 19 is pushed, it will push the pressing plate 18 to move backward. When the pressing plate 18 is pushed, it will expand in a direction away from each other. A contact flexible plate 20 is fixedly connected to the surface of the pusher 19. Then the trainee presses his legs against the contact flexible plate 20. When the contact flexible plate 20 is pressed, it will push the pusher 19 to move backward.
[0038] The lumbar support mechanism 30 includes a right-angle plate 41, and a pull plate 42 is rotatably connected to the end of the right-angle plate 41. When the telescopic plate 38 moves, the two ends of the telescopic plate 38 will retract due to the pulling force of the pull plate 42.
[0039] The correction mechanism 50 includes an elastic plate 56. When the upright 55 moves, it will squeeze the elastic plate 56. The surface of the elastic plate 56 is fixedly connected to the correction rod 57. When the elastic plate 56 is squeezed, the middle part will bend. When the middle part of the elastic plate 56 bends, it will push the correction rod 57 to move downward. When the correction rod 57 moves downward, it will fit against the student's shoulder.
[0040] There are two pressure sensors 4, which are symmetrically arranged around the monitor 1. There are also two vibration rings 5, which are symmetrically arranged on the surface of the monitor 1.
[0041] The anti-movement mechanism 10 includes a support frame 11. An auxiliary rod 12 is fixedly connected to the surface of the support frame 11. A limit groove is formed on the surface of the support frame 11. A limit telescopic rod 13 is fixedly connected to the inner wall of the limit groove. When the lifting slider 14 slides, it will squeeze the limit telescopic rod 13, causing it to retract. The lifting slider 14 is slidably connected to the inner wall of the limit groove. When the connecting column 15 moves, it will drive the lifting slider 14 to slide upward on the inner wall of the limit groove. The surface of the lifting slider 14 is fixedly connected to the connecting column 15. When the collar 16 moves upward, it will drive the connecting column 15 to move upward. A collar 16 is fixedly connected to the end of the lifting slider 14 away from the 15. Then, the student holds the surface of the pressure sensor 4 and starts doing pull-ups. When the student moves upward, it will drive the collar 16 to move upward. An extension ring 17 is slidably connected to the inner wall of the collar 16. When the student is doing pull-ups, the electrical activity signal of the muscle is detected by the electromyography sensor 2. By analyzing these signals, the sequence and intensity of muscle contraction can be determined, thereby monitoring whether the student starts the pull-up according to the correct movement pattern. This prevents the student from moving their legs randomly and causing the movement to be incorrect when doing pull-ups.
[0042] The inner wall of the pressure sensor 4 is fixedly connected to the surface of the auxiliary rod 12. The end of the limiting telescopic rod 13 away from the inner wall of the limiting groove is fixedly connected to the end of the lifting slider 14. The end of the extension ring 17 is rotatably connected to the surface of the extrusion plate 18. When the extrusion plate 18 expands, it will push the extension ring 17 to expand in a semi-circular direction away from each other and fix the trainee's legs. The surface of the monitor 1 is fixedly connected to the end of the support frame 11.
[0043] The lumbar support mechanism 30 includes an elastic frame 31. When the connecting column 15 moves upward, it compresses the elastic frame 31. A driven frame 32 is fixedly connected to the surface of the elastic frame 31. A sliding plate 33 is fixedly connected to the top of the support frame 11. When the driven frame 32 moves, it drives the sliding frame 34 to slide closer to each other on the inner wall of the sliding plate 33. The sliding frame 34 is slidably connected to the inner wall of the sliding plate 33. A limit elastic rod 35 is fixedly connected to the surface of the sliding frame 34. A driven rod 36 is fixedly connected to the surface of the sliding frame 34. When the sliding frame 34 slides, it drives the driven rod 36 to move closer to each other. A push plate 37 is rotatably connected to the end of the driven rod 36 away from the sliding frame 34. When the driven rod 36 moves, it pushes the push plate 37 to move closer to each other. A telescopic plate 38 is rotatably connected to the end of the push plate 37 away from the driven rod 36. The telescopic plate 38 has buffer elastic rods 39 fixedly connected to both ends. When the telescopic plate 38 retracts, it will drive the buffer elastic rods 39 to move closer to each other. The end of the buffer elastic rod 39 away from the telescopic plate 38 is fixedly connected to a contact rubber pad 40. When the buffer elastic rod 39 moves, it will push the contact rubber pad 40 to move closer to each other and fit against the sides of the student's waist. When the student is doing pull-ups, the joint angle sensor 3 will measure the angle change of the shoulder joint in real time. Combined with the muscle electrical signal, it will determine whether the movement of the shoulder is within the normal range. When the angle change is abnormal and the muscle contraction pattern is incorrect, it can be determined that it is an incorrect way of exerting force, such as the shoulder locking too early, which causes the angle change to not conform to the normal pull-up trajectory. This can prevent waist sprain when the student is in danger while doing pull-ups.
[0044] The surface of the connecting column 15 is fixedly connected to the bottom of the elastic frame 31. When the elastic frame 31 is compressed, the middle part will bend. When the middle part of the elastic frame 31 bends, it will push the driven frame 32 to move closer to each other. The end of the limiting elastic rod 35 away from the sliding frame 34 is fixedly connected to the surface of the right angle plate 41. The end of the pulling plate 42 away from the right angle plate 41 is rotatably connected to the top of the telescopic plate 38. When the push plate 37 moves, it will push the telescopic plate 38 forward and fit against the waist of the trainee. The two ends of the slide plate 33 are fixedly connected to the top of the support frame 11.
[0045] The corrective mechanism 50 includes a fixed plate 51. A reset elastic rod 52 is fixedly connected to the surface of the fixed plate 51. When the right-angle frame 53 moves, it pulls the reset elastic rod 52 to extend in a direction closer to each other. The end of the reset elastic rod 52 away from the fixed plate 51 is fixedly connected to the right-angle frame 53. When the U-shaped plate 54 moves, it pushes the right-angle frame 53 to move in a direction closer to each other. The surface of the right-angle frame 53 is fixedly connected to the U-shaped plate 54. When the driven frame 32 moves, it drives the U-shaped plate 54 to move in a direction closer to each other. The surface of the U-shaped plate 54... A fixed upright (55) is installed to detect whether the student's shoulders remain level during pull-ups. Pressure sensor 4 detects the student's grip strength and distribution on the bar. Different grip strength patterns can reflect the student's force application tendency, helping to determine if the force application is correct. A vibration ring (5) vibrates when the microprocessor detects incorrect force application, such as premature or excessive shoulder muscle contraction, prompting the student to adjust their force application. The intensity and frequency of the vibration can be adjusted according to the severity of the error so that the student can clearly perceive the prompts.
[0046] The end of the U-shaped plate 54 away from the right-angle frame 53 is fixedly connected to the surface of the driven frame 32. The two ends of the elastic plate 56 are fixedly connected to the ends of the uprights 55. When the U-shaped plate 54 moves, it will drive the uprights 55 to move in a direction closer to each other. The end of the fixed plate 51 away from the reset elastic rod 52 is fixedly connected to the surface of the slide plate 33.
[0047] In use, first, install the electromyography (EMG) sensor 2 on the student's shoulder, then install the joint angle sensor 3 on the student's joint, and then put the vibration ring 5 on the student's wrist. The student then presses their leg against the contact flexible plate 20. When the contact flexible plate 20 is pressed, it pushes the push frame 19 backward. When the push frame 19 is pushed, it pushes the compression plate 18 backward. When the compression plate 18 is pushed, it expands in a direction away from each other. When the compression plate 18 expands, it pushes the extension ring 17 to expand in a semi-circular direction away from each other, thus fixing the student's leg. Then, the student holds the surface of the pressure sensor 4 and begins to perform pull-ups. As the student pulls up, it moves the collar 16 upward. When the connecting column 15 moves upward, it causes the lifting slider 14 to slide upward along the inner wall of the limiting groove. As the lifting slider 14 slides, it compresses the limiting telescopic rod 13, causing it to contract. This prevents the student from moving their legs erratically during pull-ups, thus preventing improper form. During pull-ups, the muscle electrical activity signal is detected by the electromyography (EMG) sensor 2. By analyzing these signals, the sequence and intensity of muscle contraction can be determined, thus monitoring whether the student is starting the pull-up according to the correct movement pattern. When the connecting column 15 moves upward, it compresses the elastic frame 31. When the elastic frame 31 is compressed, its middle section bends. When the middle section of the elastic frame 31 bends, it pushes the driven frame 32 towards... The driven frame 32 moves towards each other, causing the sliding frame 34 to slide along the inner wall of the slide plate 33 towards each other. The sliding frame 34 then moves the driven rod 36 towards each other, which in turn pushes the push plate 37 towards each other. The push plate 37 then pushes the telescopic plate 38 forward to fit against the student's waist. The telescopic plate 38 retracts at both ends due to the pulling force of the pull plate 42. This retraction causes the buffer elastic rod 39 to move towards each other, which in turn pushes the contact rubber pad 40 towards each other, fitting against the sides of the student's waist. This provides cushioning when the student is... To prevent lower back strain during pull-ups, a joint angle sensor 3 measures the shoulder joint angle in real time while the trainee is performing pull-ups. Combined with muscle electrical signals, this determines whether the shoulder movement is within the normal range. Abnormal angle changes and incorrect muscle contraction patterns indicate incorrect force application, such as premature shoulder locking causing the angle change to deviate from the normal pull-up trajectory. When the driven frame 32 moves, it drives the U-shaped plate 54 to move closer together. The movement of the U-shaped plate 54 pushes the right-angle frame 53 to move closer together. The movement of the right-angle frame 53 pulls the return elastic rod 52 to extend closer together. Simultaneously, the movement of the U-shaped plate 54 drives the upright bar 55 to move closer together.When the upright bar 55 moves, it compresses the elastic plate 56. When the elastic plate 56 is compressed, its middle section bends. This bending pushes the corrective bar 57 downwards. As the corrective bar 57 moves downwards, it comes into contact with the student's shoulders, effectively detecting whether the student's shoulders remain level during pull-ups. During pull-ups, pressure sensor 4 detects the magnitude and distribution of the student's grip force on the bar. Different grip patterns can reflect the student's force application tendency to some extent, aiding in judging whether the force application is correct. Furthermore, the vibration ring 5 vibrates when the microprocessor determines that the student's force application is incorrect, such as premature or excessive contraction of the shoulder muscles, reminding the student to adjust their force application method. The intensity and frequency of the vibration can be adjusted according to the severity of the error so that the student can clearly perceive the prompts.
