Description

Technical Field

[0001] This invention relates to the field of sports archery technology, specifically to an archery training device with a posture feedback structure. Background Technology

[0002] Archery demands a high degree of precision in the archer's posture. The angle of the arm pushing the bow, the force exertion of the hand drawing the string, the foot placement, the head aiming posture, and the grip angle all directly affect the accuracy and stability of the shot. In traditional archery training, posture correction relies primarily on the coach's visual observation and verbal instructions, which suffers from delayed feedback, strong subjectivity, and the inability to correct errors in real time.

[0003] Meanwhile, different archers have different heights and body types, and traditional training equipment lacks targeted posture adaptation and adjustment functions. This can easily lead to archers training in non-standard compensatory postures for extended periods, which not only fails to improve training effectiveness but may also increase the risk of muscle strain. In addition, some existing simple posture training devices can only detect the posture of a single part of the body, failing to achieve coordinated detection and feedback of postures of multiple parts of the body. This makes it difficult to form a systematic posture correction system and cannot meet the needs of archers throughout the entire process from basic posture development to advanced training.

[0004] To address the aforementioned issues, this invention proposes an archery trainer with a posture feedback structure. Through the collaborative design of multiple posture feedback adjustment mechanisms, it achieves comprehensive detection and real-time feedback adjustment of the grip, bow-pushing arm, string-drawing hand, foot, and head postures, helping archers quickly establish standard posture muscle memory and improving training efficiency and accuracy.

[0020] Please see Figures 1-8 The present invention provides an archery training device with an attitude feedback structure, comprising: The grip 1 has several anti-slip parts 101 installed on its side wall. A grip force sensor 103 is fixedly installed between the inner wall of the anti-slip parts 101 and the side wall of the grip 1. An installation groove 104 is opened inside the grip 1, and a gyroscope sensor 105 is fixedly installed in the installation groove 104. The bow-pushing arm posture feedback adjustment mechanism is installed on one side of the handle 1. The bow-pushing arm posture feedback adjustment mechanism detects the posture of the bow-pushing arm through the first infrared sensor 201 on one side of the first guard arm 2 and the second infrared sensor 203 on one side of the second guard arm 202. The posture of the bow-pushing arm is adjusted by adjusting the position of the second guard arm 202. The bow hand posture feedback adjustment mechanism is installed on the top of the grip 1. The bow hand posture feedback adjustment mechanism determines the bow hand posture by detecting the tension of the first elastic rope 3 and the position of the second elastic rope 303 in the mounting part 5, and prompts the bow hand to adjust its posture automatically through the control device 601. The dual-foot posture feedback adjustment mechanism is installed at the bottom of the handle 1. The dual-foot posture feedback adjustment mechanism determines the position of the front foot through the foot pedal 403, determines the position of the rear foot through the camera 405, and adjusts the dual-foot posture by indicating the position of the dual feet through the indicator light 412. A head posture feedback mechanism is installed on the control device 601 and is used to detect and provide feedback on the head posture. Two indicator lights 501 for indicating the tilt angle of the grip 1 are fixedly installed on the side wall of the mounting piece 5.

[0021] In some embodiments, see Figure 2 , Figure 3 The bow arm posture feedback adjustment mechanism includes a fixed frame 204, a first elastic band 206, an extension frame 207, a connecting shaft 209, and a second elastic band 210. One end of the fixed frame 204 is fixedly installed on one side wall of the first guard arm 2, and the other end of the fixed frame 204 is fixedly installed on the side wall of the handle 1 near the top. The first guard arm 2 is installed on one side of the handle 1 through the fixed frame 204. The first elastic band 206 is fixedly installed on the other side wall of the first guard arm 2.

The second guard arm 202 is fixedly installed on the side wall of the connecting shaft 209. The second elastic band 210 is fixedly installed on the side wall of the second guard arm 202. Both the first guard arm 2 and the second guard arm 202 are arc-shaped parts. It should be noted that the fixing frame 204 is used to achieve a stable connection between the first arm guard 2 and the handle 1, ensuring the stability of the arm guard structure when pushing the bow; the arc-shaped design of the first arm guard 2 and the second arm guard 202 can conform to the contour of the arm, improving wearing comfort; the first elastic band 206 and the second elastic band 210 can adapt to arms of different thicknesses, ensuring that the arm guard fits tightly to the arm and avoiding detection errors caused by the displacement of the arm guard during the testing process; the extension frame 207 provides installation support for the connecting shaft 209, allowing the second arm guard 202 to rotate around the connecting shaft 209, realizing the posture adjustment function.

[0022] In some embodiments, see Figure 2 , Figure 3A protective pad 205 is fixedly installed on one side of the first protective arm 2. The protective pad 205 is an arc-shaped pad, and the arc of the protective pad 205 matches the first protective arm 2. A stepper motor 208 is fixedly installed on the top of the extension frame 207. A connecting shaft 209 is fixedly installed on the output end of the stepper motor 208. The connecting shaft 209 is rotatably connected to the extension frame 207 through the stepper motor 208. It should be noted that the pad 205 can cushion the pressure of the arm protector on the skin, reduce discomfort during long-term training, and enhance the fit between the arm protector and the arm; the first infrared sensor 201 and the second infrared sensor 203 work together to accurately capture the angle and position information of the pushing arm and transmit it to the control device 601 in real time; after receiving the command from the control device 601, the stepper motor 208 drives the connecting shaft 209 to rotate the second arm protector 202, thereby actively adjusting the bending angle and extension posture of the pushing arm and realizing real-time posture correction.

[0023] In some embodiments, see Figure 4 , Figure 5 , Figure 6 The drawarm posture feedback adjustment mechanism includes a pressure sensor 511, a second spring 512, a mounting ring 513, a movable part 304, and a contact sensor 108. The mounting part 5 is fixedly installed on the top of the grip 1. A detection cavity 510 is opened inside the mounting part 5. Several pressure sensors 511 are fixedly installed in the detection cavity 510. The mounting ring 513 is fixedly installed on the output end of several pressure sensors 511. The second elastic rope 303 is located inside the mounting ring 513. The second spring 512 is fixedly installed on the inner wall of the detection cavity 510 and the mounting ring 512. Between the 13 side walls, the second spring 512 is located on the side wall of the pressure sensor 511. Several second springs 512 are provided. One end of the first elastic rope 3 is fixedly installed on one end of the second elastic rope 303. The movable part 304 is fixedly installed on the other end of the first elastic rope 3. The bottom of the handle 1 is provided with a movable groove 106 that fits with the movable part 304. The movable part 304 is rotatably connected in the movable groove 106. A groove 107 that is connected to the movable part 106 is provided on one side of the movable groove 106. The contact sensor 108 is fixedly installed on the top of the inner wall of the groove 107. The groove 107 fits with the first elastic rope 3. It should be noted that the mounting component 5 provides a mounting carrier for the bower's posture detection component, and the detection cavity 510 provides a protective space for components such as the pressure sensor 511 and the second spring 512. When the second elastic rope 303 moves, it will cause the mounting ring 513 to squeeze the pressure sensor 511. The pressure sensor 511 detects the position of the second elastic rope 303 by the change in force, and then determines the lateral deviation posture of the bower. The second spring 512 can buffer the impact force of the moving mounting ring 513, and at the same time assist the mounting ring 513 to reset, ensuring the sensitivity of the detection. The rotation state of the movable component 304 in the movable groove 106 can reflect the tension of the first elastic rope 3. When the first elastic rope 3 is slack, it will contact the contact sensor 108, triggering a posture abnormality prompt, ensuring that the bower maintains a stable force application state.

[0024] In some embodiments, see Figure 5 The mounting component 5 has a storage slot 503, which is connected to the detection chamber 510. A third servo motor 502 is fixedly mounted on one side of the mounting component 5. A fixed shaft 504 is fixedly mounted on the output end of the third servo motor 502. The fixed shaft 504 is rotatably connected to the storage slot 503 through the third servo motor 502. A winding reel 505 is fixedly mounted on the side wall of the fixed shaft 504. The second elastic rope 303 is wound on the side wall of the winding reel 505. A connected mounting cavity 506 is opened on one side of the storage slot 503. An electric push rod 507 is fixedly mounted on the inner wall of the mounting cavity 506. A mounting plate 508 is fixedly mounted on the output end of the electric push rod 507. A clamping component 509 is fixedly mounted on one side of the mounting plate 508. The clamping component 509 fits with the second elastic rope 303. It should be noted that the storage slot 503 is used to store excess second elastic rope 303 to prevent the rope from getting tangled and affecting use; the third servo motor 502 drives the fixed shaft 504 to rotate the winding reel 505, which can realize the winding and unwinding of the second elastic rope 303 to adapt to the draw distance requirements of different shooters; the mounting cavity 506 provides installation space for the electric push rod 507, which drives the clamping member 509 to move through the mounting plate 508, which can clamp and fix the second elastic rope 303 to ensure the stability of the rope length during the draw and avoid posture deviation caused by rope slippage.

[0025] In some embodiments, see Figure 1 , Figure 4 The first elastic rope 3 has a gripping component 301 slidably connected to its side wall, and a tension sensor 302 is fixedly installed inside the gripping component 301. It should be noted that the grip 301 provides a comfortable grip for the bowstring, and its sliding design can adapt to the hand movement during the bowstring drawing process; the tension sensor 302 detects the force exerted by the bowstring in real time and transmits the data to the control device 601, so that the archer can understand his own force exertion and avoid posture deformation caused by excessive or insufficient force exertion.

[0026] In some embodiments, see Figure 7 , Figure 8 The dual-foot posture feedback adjustment mechanism includes an elastic band 4, a rotating shaft 401, a mounting shaft 402, a foot pedal 404, a first spring 406, a piezoelectric sensor 407, a first servo motor 408, a rotating component 409, a second servo motor 410, and a rotating rod 411.

The foot pedal 403 is rotatably connected to the side wall of the mounting shaft 402. One end of the first spring 406 is fixedly mounted on the bottom of the foot pedal 404, and the other end is fixedly mounted on the inner wall of the foot pedal 403. The foot pedal 404 is flexed via the first spring 406. A piezoelectric sensor 407 is fixedly installed on the inner wall of the foot pedal 403 and located at the bottom of the foot pedal 404. A first servo motor 408 is fixedly installed inside the foot pedal 403.

It should be noted that the connector 102 connects the foot posture adjustment mechanism to the handle 1, the rotating shaft 401 allows the elastic band 4 to be flexibly adjusted to adapt to different standing position requirements; the mounting shaft 402 provides rotational support for the foot pedal 403, allowing the foot pedal 403 to be flexibly adjusted according to the position of the front foot; the foot pedal 404 is connected to the foot pedal 403 through the first spring 406, which can buffer the pressure on the feet, and the piezoelectric sensor 407 detects whether the front foot is stably placed by the force on the foot pedal 404; the camera 405 captures the position information of the rear foot in real time and transmits it to the control device 601 for posture judgment; the first servo motor 408 drives the rotating component 409 to rotate, and the second servo motor 410 drives the rotating rod 411 to rotate. The two work together to adjust the illumination direction of the indicator spotlight 412, and the light spot indicates the correct standing position of the feet, so as to achieve precise adjustment of the foot posture.

It should be noted that the rotating base 6 can adjust the orientation of the control device 601 to ensure that the infrared locator 602 can accurately capture the head position; the infrared locator 602 detects the head's tilt angle, offset and other posture information in real time, transmits the data to the control device 601, and the display screen simultaneously displays the head posture parameters and correction prompts to help the shooter quickly adjust the head posture and ensure that the line of sight is consistent with the aiming direction.

[0028] In addition, the anti-slip part 101 on the grip 1 can enhance the grip friction and prevent the grip 1 from slipping during training; the grip force sensor 103 detects the grip force of the grip 1 to ensure that the shooter maintains a stable grip force; the gyroscope sensor 105 detects the tilt angle of the grip 1 in real time and provides visual prompts through the indicator light 501 on the mounting part 5. A red light indicates an abnormal tilt angle and a green light indicates a standard posture, helping the shooter to quickly adjust the posture of the grip 1.

[0029] The workflow and principle of this invention are as follows: When the archer uses the device, they first adjust their stance using a foot posture feedback adjustment mechanism: the front foot is placed on the foot pedal 404 of the foot pedal 403, the piezoelectric sensor 407 detects the position of the front foot, the camera 405 captures the position of the rear foot, and the control device 601 adjusts the illumination position of the indicator spotlight 412 according to a preset standard posture via the first servo motor 408 and the second servo motor 410, guiding the archer to adjust their stance to the standard state; then, the bow-pushing arm is placed between the first arm guard 2 and the second arm guard 202, and secured by the first elastic band 206 and the second elastic band 210, with the pad 205 conforming to the arm to provide comfortable support; the draw hand grips the handle 301, and the third servo motor 502 drives the winding reel 505 to wind up and unwind the second elastic rope 303. After being adjusted to the appropriate length, the electric push rod 507 drives the clamping part 509 to fix the second elastic rope 303. During training, the grip force sensor 103 detects the gripping force of the grip 1, the gyroscope sensor 105 detects the tilt angle of the grip 1, and the indicator light 501 provides real-time feedback on the tilt angle status. The first infrared sensor 201 and the second infrared sensor 203 detect the posture of the bow-pushing arm. If there is a deviation, the stepper motor 208 drives the second guard arm 202 to rotate for adjustment. The tension sensor 302 detects the force of the bowstring being drawn, and the pressure sensor 511 and the contact sensor 108 work together to detect the posture of the bow-drawing hand. If there is an abnormality, the control device 601 prompts for correction through the display screen. The infrared locator 602 detects the head posture and simultaneously displays adjustment suggestions on the display screen, realizing real-time detection and coordinated feedback adjustment of the whole body posture.
