Detailed implementation manners
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] Embodiment 1 As Figures 1-8 shown, an intelligent basketball training assistance device includes a device main body 1. A training dummy 4 is arranged on the upper part of the device main body 1. Two rotating mechanisms are fixedly connected to the upper part of the training dummy 4. A swing housing 30 is fixedly connected to the side of the rotating mechanism away from the training dummy 4. A fourth motor 27 is arranged on one side of the swing housing 30. A reciprocating runner 28 is arranged at the output end of the fourth motor 27. The reciprocating runner 28 is meshed and connected with a transmission member 7. A third gear 29 is meshed and connected to one side of the transmission member 7. The third gear 29 is rotatably connected to the swing housing 30. A connecting block 31 is fixedly connected to one side of the third gear 29. A telescopic housing 5 is fixedly connected to the side of the connecting block 31 away from the third gear 29. A third motor 21 is arranged inside the telescopic housing 5.
[0020] A third transmission wheel 22 is provided at the output end of the third motor 21. The third transmission wheel 22 is drivingly connected to a second transmission belt 23. On the side of the second transmission belt 23 away from the third transmission wheel 22, it is drivingly connected to a fourth transmission wheel 24. The fourth transmission wheel 24 is fixedly connected to an eccentric shaft 25. The eccentric shaft 25 is rotatably connected to a connecting plate 26. On the side of the connecting plate 26 away from the eccentric shaft 25, a prosthetic hand 6 is rotatably connected. During training, the prosthetic hands 6 on both sides are controlled by a rotating mechanism to be vertically upward and then the third motor 21 is started. The third motor 21 drives the eccentric shaft 25 to rotate. The rotation of the eccentric shaft 25 drives the connecting plate 26 to rotate, and then drives the prosthetic hand 6 to stretch up and down, so as to simulate the action of a player jumping up to intercept a shot. After the prosthetic hands 6 are driven by the rotating mechanism to horizontally extend to both sides, the fourth motor 27 is started to drive the third gear 29 to rotate reciprocally, and then drives the prosthetic hands 6 to wave up and down, simulating the action of a player dribbling past an opponent to intercept. Only a partial area of the surface of the reciprocating runner 28 is provided with gears, and teeth meshing with the reciprocating runner 28 are provided on both sides of the reciprocating runner 28 inside the transmission member 7.
[0021] The rotating mechanism includes a rotating housing 14 fixedly connected to the upper part of the training dummy 4. A fifth motor 32 is provided inside the rotating housing 14. A rotating assembly is provided at the output end of the fifth motor 32. The rotating assembly includes a fourth gear 33 provided at the output end of the fifth motor 32. The fourth gear 33 is meshingly connected to a fifth gear 34. The fifth gear 34 is rotatably connected to the rotating housing 14. On the side of the fifth gear 34 away from the rotating housing 14, a swinging housing 30 is fixedly connected.
[0022] A moving mechanism is provided at the bottom of the training dummy 4. The moving mechanism is fixedly connected to the device main body 1. The moving mechanism includes a moving groove 16 fixedly connected inside the device main body 1. A moving plate 15 is slidably connected inside the moving groove 16. A second motor 18 is provided on the upper part of the moving plate 15. A moving assembly is provided at the output end of the second motor 18. The moving assembly includes a first gear 19 provided at the output end of the second motor 18. The first gear 19 is meshingly connected to a second gear 20. The second gear 20 is rotatably connected to the moving plate 15. On the side of the second gear 20 away from the first gear 19, it is meshingly connected to a transmission rack 17. The transmission rack 17 is fixedly connected to the moving groove 16. The training dummy 4 is fixedly connected to the upper part of the moving plate 15.
[0023] In this embodiment, the built-in lithium battery pack of the device and the solar charging module 39 are integrated on the top of the device main body 1, supporting off-grid training scenarios. When a person is training, the training dummy 4 arranged in the device main body 1 can make an intercepting action on the person, thus assisting the person in training. When the person is performing shooting training, the fifth motor 32 can drive the fourth gear 33 to rotate. The rotation of the fourth gear 33 drives the meshing-connected fifth gear 34 to rotate, and the rotation of the fifth gear 34 can drive the fixedly-connected swing housing 30 to rotate, and then can drive the two prosthetic hands 6 to move vertically upward. After the adjustment is completed, starting the third motor 21 can drive the third driving wheel 22 to rotate. The rotation of the third driving wheel 22 drives the fourth driving wheel 24 connected by the second transmission belt 23 to rotate, and the rotation of the fourth driving wheel 24 can drive the fixedly-connected eccentric shaft 25 to rotate. The rotation of the eccentric shaft 25 drives the connecting plate 26 to also rotate. The rotation of the connecting plate 26 can drive the rotationally-connected prosthetic hand 6 to stretch up and down, thereby imitating the action of a player jumping up to intercept a shot, increasing the confrontation during the person's shooting training.
[0024] Starting the fifth motor 32 again can also drive the prosthetic hand 6 to horizontally extend to both sides. Subsequently, starting the fourth motor 27 can drive the reciprocating runner 28 to rotate. The rotation of the reciprocating runner 28 can drive the meshing-connected transmission member 7 to move up and down reciprocally, and the reciprocal movement of the transmission member 7 can drive the meshing-connected third gear 29 to rotate reciprocally. And through the reciprocal rotation of the third gear 29, the fixedly-connected connecting block 31 can be driven to swing, and then drive the prosthetic hand 6 to swing up and down, thereby imitating the action of a player intercepting and dribbling past an opponent. The person can perform basketball dribbling past an opponent training through the continuously swinging prosthetic hand 6. The device can conduct different types of basketball confrontation training on the person through the training dummy 4, not only enriching the training content, but also effectively improving the training effect. During training, starting the second motor 18 can also drive the first gear 19 to rotate. The rotation of the first gear 19 drives the second gear 20 to rotate, and the rotation of the second gear 20 can move along the meshing-connected transmission rack 17, thereby driving the training dummy 4 to move and adjusting the intercepting position of the training dummy 4.
[0025] Multiple sensors are installed on the device main body 1 and the training dummy 4, including the IMU sensor 35 installed on the prosthetic hand 6. Such sensors are crucial for capturing the details of fast-changing movements, such as the interception speed, angle, and direction of the prosthetic hand 6. The laser range finder sensor 36 is set at the basket to accurately measure the distance between the ball and the basket when the athlete shoots, as well as the height of the ball's flight trajectory, which helps analyze the shooting accuracy. The position sensors are distributed throughout the device main body and the dummy, and through ultrasonic or infrared technology, they achieve precise tracking of spatial positions, used to determine the relative positions between the athlete and the dummy, as well as the movement path of the athlete. The force sensors are installed at the contact parts of the prosthetic hand to measure the magnitude of the force when the athlete touches the prosthetic hand, helping to evaluate the athlete's confrontation ability and skills. To ensure the accuracy and real-time nature of the data, the data acquisition frequency of the IMU sensor 35 and the laser range finder sensor 36 should be no less than 100 Hz to capture the details of fast-changing movements. The data acquisition frequency of the position sensors and the force sensors can be appropriately reduced to 50 Hz because their changes are relatively slow, but sufficient sampling rates still need to be ensured to reflect the athlete's training status. At the same time, the device is also equipped with a high-definition camera to capture the action videos of the athlete. The collected data will be transmitted to the built-in processor of the device or the cloud server. By using a convolutional neural network to perform image processing on the video frames captured by the camera, the trajectory features of the shooting action are extracted.
[0026] The CNN can automatically learn the spatial hierarchy in the image and is very effective for identifying and analyzing shooting actions. By analyzing features such as the curvature and speed change of the shooting trajectory, the shooting accuracy and skills can be evaluated. The long short-term memory network is good at processing time series data. In basketball training, the LSTM can be used to analyze the movement path and speed change of the athlete and predict the possible breakthrough path. By training the LSTM model, the athlete's movement patterns and habits can be identified, providing an intelligent confrontation strategy for the training dummy and increasing the practicality and challenge of the training. Among them, low-speed sensors (such as force sensors and position sensors) use the I²C protocol to transmit data, and high-speed sensors (such as six-axis IMU and cameras) use the SPI protocol to ensure data real-time nature. Through the protocol hierarchical design, the system efficiency is improved, meeting industrial standards.
[0027] Embodiment 2 As Figures 1-8 shown, a regulating mechanism is fixedly connected to the front end of the device main body 1. The regulating mechanism includes a regulating housing 3 fixedly connected to the upper part of the device main body 1. A first motor 13 is arranged inside the regulating housing 3, and a regulating component is arranged at the output end of the first motor 13.
[0028] The adjustment assembly includes a first driving wheel 10 arranged at the output end of the first motor 13. The first driving wheel 10 is drivingly connected with a first driving belt 11. The first driving belt 11 is drivingly connected with a second driving wheel 12 on the side away from the first driving wheel 10. A threaded rod 9 is fixedly connected to the lower part of the second driving wheel 12. The threaded rod 9 is rotatably connected to the adjustment housing 3. A slider 8 is threadedly connected to the upper part of the threaded rod 9. The slider 8 is slidably connected to the adjustment housing 3. A basket 2 is fixedly connected to the side of the slider 8 away from the threaded rod 9. Two sliding rails are arranged at the front end of the adjustment housing 3, and the slider 8 can be slidably connected through the sliding rails.
[0029] In this embodiment, the device includes a sensor assembly, an actuator assembly and a communication module with standardized interfaces. The communication module supports dual-mode connection of Bluetooth 5.0 and Wi-Fi and is used for data interaction with the mobile APP. Before basketball training, starting the first motor 13 can drive the first driving wheel 10 to rotate. The rotation of the first driving wheel 10 drives the second driving wheel 12 drivingly connected through the first driving belt 11 to rotate. The rotation of the second driving wheel 12 can drive the fixedly connected threaded rod 9 to rotate. The rotation of the threaded rod 9 can drive the slidably connected slider 8 to move. The movement of the slider 8 can drive the basket 2 fixedly connected to the front end to move, so as to adjust the height of the basket 2, enabling the device to flexibly adjust the height of the basket 2 according to the height of the user and improving the use effect of the device.
