[0002] In existing basketball training and entertainment equipment, especially the children's basketball machines commonly seen in playgrounds or gymnasiums, a mechanism of rolling back the basketball after shooting is generally adopted.

[0003] This mechanism requires the setting of a basketball rolling track, resulting in a relatively large overall structure of the equipment and occupying more space. In addition, this design also has certain limitations on the training of the basketball's movement trajectory and feel, and cannot effectively simulate the shooting experience and training requirements in actual basketball games.

[0004] Existing basketball recycling devices usually can only simply return the basketball to the user, lacking the functions of automatically correcting the position after basketball shooting and throwing in a specific direction. This not only limits the shooting training effect of the user, but also reduces the fun and interactivity of the equipment to a certain extent, and cannot meet the training needs of demanding basketball enthusiasts or professional athletes. These traditional designs mainly rely on the basketball to roll back along the preset track, restricting the flexibility and adaptability of the equipment under different sites and usage conditions.

[0050] A method for an automatic basketball shooting machine that automatically corrects the position and directionally throws the basketball after shooting, the method comprising the following steps:

[0051] Step 1, receiving the basketball 19 after shooting;

[0052] Step 2, guiding the basketball 19 to the correction position through the guiding device;

[0053] Step 3, automatically correcting the position of the basketball 19;

[0054] Step 4, throwing the basketball 19 according to the set angle and direction.

[0055] The guiding device consists of the inclined extension rod 14 and the annular funnel net 15. Multiple inclined extension rods 14 are fixed to the basketball frame 2 at the bottom to form an inclined structure to guide the basketball to the central position. The annular funnel net 15 is connected between multiple inclined extension rods 14 to form an annular channel. After the basketball is shot, it rolls between the first ball-feeding wheel 6 and the second ball-feeding wheel 7 in the concave cavity 5 through the guidance of the annular funnel net 15 and the inclined extension rod 14, and is ready to enter the correction and throwing process.

[0056] And the Internet of Things application technology is adopted to realize the automatic recovery of the device and the direction-adjustable automatic throwing. The specific steps are as follows:

[0057] I. Induction Device: The induction device includes multiple infrared sensors and position sensors for detecting the entry and position of the basketball. These sensors are arranged at the entrance of the concave cavity 5 and in the ball-feeding channel.

[0058] II. Cooperation between multiple motors and induction devices: Multiple motors are used to drive the first serving wheel 6, the second serving wheel 7, and the ball feeding wheel 8 respectively. After a basketball enters the serving channel 12 and is detected by an infrared sensor known to those skilled in the art, the signal is transmitted to the controller, and the controller instructs the ball feeding wheel 8 to start and send the basketball into the serving channel.

[0059] III. Automatic correction: When a basketball enters the serving channel 12, a position sensor detects the position of the basketball, and the controller adjusts the rotation speed and direction of the ball feeding wheel 8 according to a preset algorithm to ensure that the basketball reaches the correct correction position.

[0060] The preset algorithm is as follows. For example, assuming that the system needs to throw the basketball at an angle of 45 degrees and a speed of 8 m / s, the algorithm steps are as follows:

[0061] 1. Determine the target position and angle: The system determines the position and attitude of the basketball in the serving channel based on the sensor data.

[0062] 2. Calculate the speed and direction: The system calculates the required rotation speed of the serving wheel and the initial thrust of the ball feeding wheel 8. The specific calculation formulas are as follows:

[0063] Rotation speed of the serving wheel = target speed ÷ radius of the serving wheel

[0064] Initial thrust of the ball feeding wheel = target speed × mass of the basketball

[0065] 3. Correction and adjustment: The system adjusts the rotation speed and thrust of the serving wheel and the ball feeding wheel according to the above calculation results, and monitors the position and attitude of the basketball in real time through sensors for fine-tuning to ensure the throwing accuracy.

[0066] 4. Execute the throw: When the basketball reaches the correct position, the controller instructs the serving wheel and the ball feeding wheel to start simultaneously and throw the basketball at the preset speed and angle.

[0067] 5. Example calculation:

[0068] Target speed: 8 m / s.

[0069] Target angle: 45 degrees.

[0070] Radius of the serving wheel: 0.1 m.

[0071] Mass of the basketball: 0.6 kg.

[0072] At this time, the calculated rotation speed of the serving wheel is: Rotation speed of the serving wheel = 8 m / s ÷ 0.1 m = 80 rps.

[0073] And the calculated initial thrust of the ball feeding wheel is: Initial thrust of the ball feeding wheel = 8 m / s × 0.6 kg = 4.8 N.

[0074] The controller adjusts the speed of the serving wheel to 80 revolutions per second and applies an initial thrust of 4.8 N to the ball-feeding wheel to ensure that the basketball is thrown at a speed of 8 m / s at an angle of 45 degrees.

[0075] IV. Directional throwing: The controller controls the rotation speeds of the first serving wheel 6 and the second serving wheel 7 according to the set angles and directions, adjusts the throwing force and direction, so that the basketball is accurately thrown at a predetermined angle and speed.

[0076] V. Cloud collection and control of device status: The Internet of Things system connects the device to the cloud server through a wireless network to achieve real-time monitoring and remote control. The main steps are as follows:

[0077] 1. Data collection: The status data of each sensing device and motor are collected by sensors and uploaded to the cloud server through the controller. The data includes the current position of the basketball, the working status of the device, the rotation speed of the motor, etc.

[0078] 2. Real-time monitoring: The cloud server processes the collected data in real time and displays the working status of the device through the control interface. Managers can monitor the operation of the device through a web page or a mobile application.

[0079] 3. Remote control: Managers can remotely adjust the settings of the device through the cloud control system, including adjusting the serving angle, speed, and starting / stopping the device, etc. The cloud server transmits the control instructions to the device controller to achieve precise control of the device.

[0080] VI. Automatic correction and directional throwing.

[0081] 1. Receiving the basketball after shooting: The basketball after shooting is guided by the guiding device into the concave cavity 5 and enters the serving channel 12.

[0082] 2. Automatic correction: When the basketball enters the serving channel 12, the infrared sensor detects the position of the basketball. The controller adjusts the rotation speed and direction of the ball-feeding wheel 8 according to the sensor signal and sends the basketball to the correct correction position.

[0083] 3. Directional throwing: According to the preset angles and directions, the controller adjusts the rotation speeds of the first serving wheel 6 and the second serving wheel 7, and controls the throwing force and angle. The basketball is accurately thrown to simulate a real shot.

[0084] 4. Device structure:

[0085] Inclined extension rod 14: Used to guide the basketball to roll and ensure that the basketball enters the concave cavity 5.

[0086] Annular funnel net 15: Connected between the inclined extension rods to form a basketball guiding channel.

[0087] The first serving wheel 6, the second serving wheel 7, and the ball delivery wheel 8 are driven by multiple motors respectively. The motors adjust the speed and direction through controllers to ensure the position correction and directional throwing of the basketball.

[0088] Infrared sensors and position sensors: placed in key locations to detect basketball position and equipment status in real time.

[0089] 7. Multiple fun modes and user interactions.

Receive the basketball 19 after shooting: Guide the basketball 19 to the calibration position through the basketball receiving guiding funnel 1, ensuring that the basketball 19 can be smoothly introduced into the throwing machine whether the device is fixedly installed or movably installed.

[0127] 2. Automatically calibrate the position: Use the induction device to detect the position of the basketball, and control the ball feeding wheel 8 to send the basketball 19 into the serving channel 12 to ensure that the basketball 19 is calibrated at the correct position.

[0128] 3. Throw the basketball 19 in a specific direction: According to the preset angle and direction, drive the serving wheel by the motor to throw the basketball 19. Regardless of the installation position of the device, accurate directional throwing can be achieved.

[0129] Among them, for the change of the angle, for example, the throwing angle can be changed by using an eccentric wheel:

[0130] An eccentric wheel is a mechanical device that can convert rotational motion into linear motion or angular change. Connecting the basketball throwing machine 3 to the eccentric wheel, the throwing angle can be changed by adjusting the position of the eccentric wheel.

[0131] Specific operation: Install the eccentric wheel at the bottom or side of the throwing machine, and connect the rotation axis of the eccentric wheel to the angle adjustment axis of the throwing machine 3. When rotating the eccentric wheel, the eccentric part of the eccentric wheel will push or pull the angle adjustment axis of the throwing machine 3, thereby changing the throwing angle.

[0132] For example: If you want to increase the throwing angle, rotate the eccentric wheel to its maximum eccentric position, so that the angle adjustment axis of the throwing machine 3 is pushed to the highest point; if you want to decrease the throwing angle, rotate the eccentric wheel to its minimum eccentric position, so that the angle adjustment axis is pulled back to the lowest point.

[0133] Among them, for the change of the angle, the throwing angle can also be changed by using a screw lifting mechanism:

[0134] The screw lifting mechanism realizes the adjustment of height or angle by rotating the screw.

[0135] Specific operation: Install the screw lifting mechanism on the support frame of the throwing machine 3. One end of the screw is connected to the angle adjustment axis of the throwing machine 3, and the other end is fixed on the support frame. By rotating the screw, the tilt angle of the throwing machine 3 can be adjusted.

[0136] For example: Rotate the screw clockwise, the angle adjustment axis of the throwing machine 3 will rise, and the throwing angle will increase; rotate the screw counterclockwise, the angle adjustment axis will drop, and the throwing angle will decrease.

[0137] Among them, for the change of the angle, the throwing angle can also be changed by using a screw lifting mechanism:

[0138] The hydraulic cylinder pushes the piston rod through hydraulic pressure to achieve angle adjustment.

[0139] Specific operation: Fix the hydraulic cylinder on the support structure of the throwing machine 3, and connect the piston rod to the angle adjustment shaft of the throwing machine 3. By controlling the hydraulic pressure of the hydraulic cylinder, push or pull the piston rod, thereby changing the angle of the throwing machine 3.

[0140] For example: Increase the hydraulic pressure, the piston rod extends, the angle adjustment shaft of the throwing machine 3 is pushed up, and the throwing angle increases; reduce the hydraulic pressure, the piston rod retracts, the angle adjustment shaft drops, and the throwing angle decreases.

[0141] 4. Multiple fun modes: Provide functions such as scanning code for payment to start and fun battle report broadcasting, increasing the interactive fun of users and improving the training effect.

[0142] In this embodiment, the automatic correction and directional throwing mechanism of the basketball 19 after shooting is further optimized to adapt to different site requirements, for example:

[0143] 1. The device is fixedly installed on the basketball hoop 2 to ensure stable operation and is suitable for fixed sites such as gymnasiums. The setting of the basketball receiving guide funnel 1 ensures that the basketball 19 can be smoothly introduced into the throwing machine, improving the working efficiency of the device.

[0144] 2. The device can be movably installed to adapt to the changing site requirements, such as homes, playgrounds, etc. The design of the basketball receiving guide funnel 1 ensures that the basketball 19 can be smoothly introduced regardless of the change in the position of the device, improving the adaptability of the device.

[0145] In terms of improving user experience and training effect:

[0146] 1. The automatic correction and directional throwing mechanism provides a real shooting experience, improves the training effect, and meets the needs of high - requirement basketball 19 enthusiasts and professional athletes.

[0147] 2. Multiple fun modes enhance the interactivity and entertainment of the device, attracting more users to participate.

[0148] This embodiment significantly improves the user experience and training effect of the self - service shooting machine through flexible installation methods, reliable guide funnel design, and precise automatic correction and directional throwing mechanism.

[0149] Embodiment 3:

[0150] This embodiment provides a self-service basketball shooting machine that is suitable for the mall environment and can automatically correct the position and throw the basketball in a specific direction after shooting. It is specially designed to ensure safety and user experience in public places. The core of this embodiment is to ensure that the thrown basketball will not cause interference or safety hazards to the interior of the mall, and to improve the interactivity and intelligence level of the device.

[0151] I. Device Structure.

[0152] Basketball receiving guiding funnel 1: It is composed of multiple inclined extension rods 14 and an annular funnel net 15, and is arranged below the basketball frame 2. The inclined extension rods 14 guide the basketball into the annular funnel net 15 to ensure that the basketball 19 enters the throwing machine.

[0153] Basketball throwing machine 3: It is fixedly connected or movably positioned and cooperates with the basketball frame 2. The basketball throwing machine 3 includes a housing seat 4, a concave cavity 5, a first serving wheel 6, a second serving wheel 7, and a ball feeding wheel 8.

[0154] Gravity sensing pedal: It is arranged on the ground in the throwing area. The pedal is embedded with a gravity sensor and a camera, which are used to detect the position and posture of the user.

[0155] Receiving basket: It is located in front of the throwing landing point to prevent the basketball from rolling out of the designated area when there is no one to receive it.

[0156] II. Automatic Correction and Directional Throwing Mechanism.

[0157] The device receives the basketball 19 after shooting through the basketball receiving guiding funnel 1: An induction device is used to detect the position of the basketball 19. After the basketball 19 enters the throwing machine, the first serving wheel 6 and the second serving wheel 7 work together to automatically correct the position of the basketball 19.

[0158] Directional throwing mechanism: The controller drives the serving wheel through a motor to throw the basketball 19 at a specific angle according to the preset angle and direction. After the user steps on the gravity sensing pedal and stays for 3 seconds, the device starts to throw. When the camera detects that the user is facing the throwing direction, the device starts the throwing program.

[0159] III. Algorithms and Calculation Methods.

[0160] In order to adapt to users of different ages, the device collects the height and weight data of the user through the gravity sensor and the camera, and uses the following algorithm for adjustment to throw to a height more suitable for people of different age groups:

[0161] 1. Data collection:

[0162] The gravity sensor measures the user's weight.

[0163] The camera measures the user's height and identifies the user's age group through an AI pre-trained model.

[0164] 2. Algorithm calculation:

[0165] Based on the user's weight and height, determine the appropriate throwing force and angle. For example:

[0166] If the user is a child, the throwing angle is set relatively low (e.g., 30 degrees) and the force is small.

[0167] If the user is an adult, the throwing angle is set relatively high (e.g., 45 degrees) and the force is large.

[0168] 3. Specific implementation algorithm:

[0169] Calculation of target speed: The target speed is equal to the square root of the user's weight divided by the standard weight, and then multiplied by the reference speed.

[0170] Calculation of the rotation speed of the serving wheel: The rotation speed of the serving wheel is equal to the target speed divided by the radius of the serving wheel.

[0171] Calculation of the initial thrust of the ball-feeding wheel: The initial thrust of the ball-feeding wheel is equal to the target speed multiplied by the mass of the basketball.

[0172] For example, assuming the reference speed is eight meters per second and the standard weight is seventy kilograms:

[0173] User weight is thirty kilograms and height is one hundred and twenty centimeters (child):

[0174] The target speed is equal to the square root of thirty kilograms divided by seventy kilograms, and then multiplied by eight, which is equal to 5.73 meters per second.

[0175] User weight is seventy kilograms and height is one hundred and eighty centimeters (adult):

[0176] The target speed is equal to the square root of seventy kilograms divided by seventy kilograms, and then multiplied by eight, which is equal to eight meters per second.

[0177] IV. Safety mechanism.

[0178] 1. Gravity-sensing pedal:

[0179] Function: Ensure that the basketball is thrown only after the user stands firmly on the pedal.

[0180] Specific implementation: The pedal is embedded with a gravity sensor. When the user stands on the pedal, the sensor detects a change in pressure. If the user stands continuously and stably on the pedal for 3 seconds, the system confirms that the user is ready and then starts to throw the basketball. This prevents the risk of accidentally starting the device when the user is not standing firmly.

[0181] 2. Camera detection:

[0182] Function: Ensure that the user throws the ball towards the throwing area.

[0183] Specific implementation: The device is equipped with a camera, which uses an AI pre-trained model to identify the user's facing direction. The system will only start the throwing program when it detects that the user is facing the throwing direction. If the user turns their head or moves away from the throwing direction, the system will pause the throwing operation. This mechanism prevents the basketball from being accidentally thrown in an unsafe direction.

[0184] 3. Receiving basket:

[0185] Function: Prevent the basketball without a receiver from rolling out of the designated area and ensure safety in the mall.

[0186] Specific implementation: A receiving basket is set at the landing area of the basketball. The receiving basket is designed as a fixed structure, which can effectively catch the basketball and prevent it from rolling out of the court or into the crowd area when there is no receiver. This not only ensures that the basketball does not fly around randomly but also improves the safety and reliability of the device.

[0187] Through the intelligent detection of the gravity sensing pedal and the camera, this embodiment ensures the safety and efficiency of the device in public places, and through diverse interaction modes, enhances the user experience and participation.
