DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4 A single person training tennis device includes a ball body 1, which is the main body of the entire training device and is designed as a spherical shape to simulate the shape and flight characteristics of a real tennis ball. The ball body 1 includes a shell 11, which is a spherical shape and wraps around the outside of the ball body 1 to protect the internal electronic components and mechanical structure from damage.

[0024] A middle part of the shell 11 is provided with an exhaust disc 12, which is located in the middle part of the ball body 1 inside to control the rebound and hit posture of the ball body 1. When the ball body 1 is hit, the exhaust disc 12 can simulate the real rebound effect by adjusting the discharge of gas.

[0025] A side of the exhaust disc 12 is sequentially provided with a motor module 19, a propeller 16, a fan 17 and a camera 18. The motor module 19 is responsible for driving the propeller 16 and the fan 17, thereby controlling the flight posture of the ball body 1, such as flight height, speed and direction. The camera 18 is also located on one side of the exhaust disc 12 and fixed on the shell 11, which is used to shoot the scene around the ball body 1, thereby providing certain information in the subsequent action response.

[0026] The other side of the exhaust disc 12 is sequentially provided with a WiFi module 15, a micro air pump 14 and an infrared sensor 13. The WiFi module 15 is located on the other side of the exhaust disc 12, and is used to realize the wireless connection between the ball 1 and external devices such as smart phones, tablets and the like. Through the WiFi module 15, the trainer can remotely control the flight parameters of the ball 1, receive training data, and even watch real-time video feedback. The micro air pump 14 is also located on the other side of the exhaust disc 12 and works with the exhaust disc 12. When the ball 1 is hit or touches the wall, the micro air pump 14 releases gas through the exhaust disc 12 to simulate the real rebound effect. The precise control of the micro air pump 14 makes the rebound effect more realistic.

[0027] A gyroscope 121 is arranged in the middle of the exhaust disc 12. The gyroscope 121 maintains the stability of the whole ball 1, and the gyroscope 121 is used to detect the attitude change of the ball 1, thereby helping to control the ball 1 to remain stable. In addition, the gyroscope 121 is also used to accurately measure the rotation speed or direction of the exhaust disc 12, and provides data for the monitoring and control of the ball 1.

[0028] An air duct 122 is arranged inside the exhaust disc 12, and the air duct 122 is communicated from the middle of the exhaust disc 12 to the outside of the exhaust disc 12 by three merging into one. In the process of the ball 1 being hit, gas is delivered into the exhaust disc 12 by the micro air pump 14, and then the gas is sprayed out from the inside to the outside through the air duct 122 at a specific position, thereby playing the role of flying the ball 1 and simulating the effect of being hit or flying.

[0029] Two mounting blocks 111 are arranged at both ends of the inside of the shell 11, and the mounting blocks 111 are used to fix the components inside the shell 11. Here, it refers to the positions of both ends of the inside space of the shell 11. Since there are many parts inside the shell 11 and it is necessary to ensure that each part is on the same axis during installation, the two mounting blocks 111 at both ends support each part inside. The mounting blocks 111 provide reliable fixing points to ensure that the internal components can be stably installed inside the shell 11.

[0030] The WiFi module 15 includes two mutually buckled brackets 151, and a WiFi chip 152 is arranged between the two brackets 151. The brackets 151 are fixedly installed on the mounting blocks 111. The brackets 151 serve as the support structure of the WiFi module 15, and form a stable frame through mutual buckling, which is used to protect and support the internal WiFi chip 152, and fix the entire WiFi module 15 on the mounting blocks 111 through the brackets 151. Through the WiFi module 15, data interconnection can be realized, so as to realize real-time data aggregation and unified control of each component through the total chip 192.

[0031] The motor module 19 includes two mutually interlocked support frames two 191, between which a total chip 192 and a micro motor 193 are arranged, and the total chip 192 is used to control the micro motor 193. The support frame two 191 serves as the supporting structure of the motor module 19, and forms a stable frame through mutual interlocking, which is used to protect and support the internal total chip 192, and the entire motor module 19 is fixed on another mounting block 111 through the support frame two 191. The total chip 192 not only directly controls the micro motor 193, but also internally provides an automatic cruise unmanned aerial vehicle system. This system integrates advanced algorithms, can receive and process sensor data in real time, intelligently adjust the flight attitude and path, and ensure that the ball 1 maintains stable flight in a variable environment. Through the signal output by the WiFi module 15 in the ball 1, the position information of the special racket is obtained, and the real travel route is planned through its own algorithm, and the inclination degree of the exhaust disc 12 is controlled to control the ball 1 to move along the predetermined route.

[0032] The micro motor 193 is assembled with the propeller 16 and the fan 17. The propeller 16 generates thrust or pull force through its rotating action, which is used to push the entire ball 1 forward or provide lift, and the propeller 16 converts the rotating power provided by the micro motor 193 into power to realize the moving or lifting function. The fan 17 generates airflow by rotating, which is used to create wind flow. The two cooperate with each other to control the flight attitude of the ball 1, such as flight height, speed and direction.

[0033] The infrared sensor 13 and the camera 18 are respectively embedded in the two ends of the shell. The infrared sensor 13 and the camera 18 are embedded in the two ends of the shell, but still have a part exposed in the external environment, so that they can receive infrared radiation and light from the outside, thereby obtaining a wider field of view and receiving more environmental information. The camera 18 and the infrared sensor 13 are used in cooperation, and no matter in the process of hitting, touching the wall or flying, the infrared sensor 13 and the camera 18 will detect the surrounding environment in real time, such as the position of obstacles or trainers, which helps to realize the obstacle avoidance and automatic reset functions, and ensures that the ball 1 will not collide with obstacles during flight and can automatically return to the user's hand.

[0034] Working principle: when training with the training ball 1, the ball 1 is hit by a special racket. At the moment of being hit, the infrared sensor 13 and the camera 18 detect the hitting condition of the special racket on the ball 1, and the total chip 192 in the ball 1 controls the micro air pump 14, which controls the exhaust disc 12 in the ball 1 through the micro air pump 14. The micro air pump 14 can spray the air through the corresponding air channel 122 of the hit position, thereby simulating the effect of hitting the ball 1. The gyroscope 121 in the exhaust disc 12 keeps the stability of the whole ball 1 during the hitting process. Similarly, when the ball 1 is hit to the ground or the wall, the internal exhaust disc 12 will simulate the effect of rebounding by exhausting. During the flight after being hit, the total chip 192 controls the micro motor 193 to rotate, further controls the propeller 16 and the fan 17 in the ball 1 to rotate. The infrared sensor 13 and the camera 18 distinguish the relative height, control the fan 17 and the propeller 16 in the ball 1 through linkage, so that the ball 1 realizes accurate indoor positioning, hovering and smooth flight to the preset position, and more accurately restores the trajectory and speed of the ball 1 during being hit, which is more in line with the actual situation. Thus, the real trajectory, speed and direction of the ball when being hit can be simulated, which is more conducive to improving the training effect of the trainee.
