Description

TECHNICAL FIELD

[0001] The present application relates to the field of tennis action skill training, in particular to an intelligent auxiliary tennis hitting method. BACKGROUND

[0002] Tennis is a netted confrontation project, which often needs to predict and grasp the accurate swing (lead) racket timing in advance when the opponent swings or is about to swing the ball, so as to further find the correct hitting point (range) in the appropriate area in front of the body. However, most of the existing tennis action auxiliary devices are for recording the swing action data of the racket, which is used for post-analysis and feedback, and there is no related device and method for providing intelligent assistance to the exerciser in the dynamic process of hitting the ball. SUMMARY

[0003] The main purpose of the present application is to provide an intelligent auxiliary tennis hitting method, which aims to make the exerciser more accurate in grasping the timing of pulling the racket backward and swinging the racket forward in the hitting process, so as to realize the assistance and correction of the tennis hitting action timing.

[0004] Therefore, the intelligent auxiliary tennis hitting method provided by the present application comprises the following steps:

[0005] Step one, wearing an auxiliary device on the arm of the exerciser holding the racket, the first impactor and the second impactor are respectively arranged on the inner side and the outer side of the arm holding the racket on the auxiliary device, a pressure sensor is arranged in the training tennis, when the partner feeds the ball to the exerciser on the opposite side of the court, the impact force of the racket on the training tennis is collected by the pressure sensor in the training tennis at the moment when the racket hits the training tennis, and a first feedback signal is sent to the first controller in the training tennis, the first controller sends a first wireless control signal to the second controller of the auxiliary device to control the first impactor to send a mechanical pulse to the inner side of the exerciser's arm, reminding the exerciser to immediately make the action of pulling the racket backward;

[0006] Step two, when the training tennis flies over the net and bounces up at the moment when it falls to the court where the exerciser is located, the impact force of the court on the training tennis is collected by the pressure sensor in the training tennis, and a second feedback signal is sent to the first controller in the training tennis, the first controller sends a second wireless control signal to the second controller of the auxiliary device to control the second impactor to send a mechanical pulse to the outer side of the exerciser's arm, reminding the exerciser to immediately make the action of swinging the racket forward;

[0007] Step three, when the exerciser swings the racket to hit the ball, the impact force of the racket on the training tennis is collected by the pressure sensor in the training tennis, and a third feedback signal is sent to the first controller in the training tennis, the first controller sends a third wireless control signal to the second controller of the auxiliary device, but this signal is an empty signal, and the first impactor and the second impactor do not send a mechanical pulse;

[0008] Step 4: When the ball flies from the trainee's court over the net and bounces up onto the sparring partner's court, the impact force of the court on the training tennis ball is collected by the pressure sensor inside the training tennis ball and sends a fourth feedback signal to the first controller inside the training tennis ball. The first controller sends a fourth wireless control signal to the second controller of the auxiliary device. This signal is also an empty signal, and the first and second impactors do not emit mechanical pulses.

[0009] Step 5: When the sparring partner hits the ball that the trainee has returned to the court again, repeat the above steps until the training ends; if the ball goes into the net, out of bounds, or any other mistake occurs, the sparring partner will serve again.

[0010] Specifically, control switches are provided on both the training tennis balls and the auxiliary devices.

[0011] Specifically, the training tennis ball is equipped with a wireless charging port.

[0012] Specifically, the auxiliary device is attached to the practitioner's racket arm via Velcro.

[0013] Specifically, the auxiliary device has a groove adapted to the racket arm, and a first impactor and a second impactor are respectively provided on both sides of the groove.

[0014] Specifically, the training tennis ball has an impact ball inside its hollow cavity, the pressure sensor is disposed on the outer surface of the impact ball, and the first controller is disposed inside the impact ball.

[0015] Specifically, multiple pressure sensors are evenly arranged on the impact ball.

[0016] Specifically, the tennis ball signal control switch is wireless. After a mishit, an observer is placed outside the court. When the observer observes the mishit, they hold the tennis ball signal control switch and press button B to cut off the tennis ball's working circuit. The signal transmitter inside the tennis ball is reset to standby mode. At this time, even if the tennis ball is hit, the internal signal generator will not transmit a signal to the auxiliary equipment, and the auxiliary equipment will not work. When the tennis ball's working circuit needs to be activated, button A of the tennis ball signal control switch is pressed to connect the working circuit. The training partner can then hold the racket and serve again, following the above steps for training.

[0017] Compared with the prior art, the present invention has the following beneficial effects: after predicting the direction of the ball coming from the opposite court during the hitting process, the practitioner can more accurately grasp the appropriate timing of pulling back the racket and swinging forward, thereby providing assistance and correction for the timing of tennis hitting action.

[0027] See Figures 1-3 An intelligent method for assisting tennis shots includes the following steps:

[0028] Step 1: An auxiliary device 2 is worn on the racket-holding arm 1 of the trainee. The auxiliary device 2 has a first impactor 3 and a second impactor 4 located on the inner and outer sides of the racket-holding arm 1, respectively. A pressure sensor 6 is installed in the training tennis ball 5. When the coach feeds the ball to the trainee from the opposite side of the court, the impact force of the racket on the training tennis ball 5 is collected by the pressure sensor 6 inside the training tennis ball 5 at the moment the racket hits the training tennis ball 5. The sensor 6 then sends a first feedback signal to the first controller inside the training tennis ball 5. The first controller sends a first wireless control signal to the second controller of the auxiliary device 2 to control the first impactor 3 to emit a mechanical pulse to the inner side of the trainee's upper arm, reminding the trainee to immediately make a backswing motion. At the same time, the trainee anticipates the direction of the ball coming from the opposite side of the court.

[0029] Step 2: When the training tennis ball 5 flies over the net and bounces up on the player's side of the court, the impact force of the court on the training tennis ball 5 is collected by the pressure sensor 6 inside the training tennis ball 5 and sends a second feedback signal to the first controller inside the training tennis ball 5. The first controller sends a second wireless control signal to the second controller of the auxiliary device 2 to control the second impactor 4 to emit a mechanical pulse to the outside of the player's upper arm, reminding the player to immediately make a forward swing motion.

[0030] Step 3: When the trainee swings the racket and hits the ball, the impact force of the racket on the training tennis ball 5 is collected by the pressure sensor 6 inside the training tennis ball 5 and a third feedback signal is sent to the first controller inside the training tennis ball 5. The first controller sends a third wireless control signal to the second controller of the auxiliary device 2, but this signal is an empty signal, and the first impactor 3 and the second impactor 4 do not emit mechanical pulses.

[0031] Step 4: When the ball flies from the player's court over the net and bounces up on the sparring partner's court, the impact force of the court on the training tennis ball 5 is collected by the pressure sensor 6 inside the training tennis ball 5 and a fourth feedback signal is sent to the first controller inside the training tennis ball 5. The first controller sends a fourth wireless control signal to the second controller of the auxiliary device 2. This signal is also an empty signal, and the first impactor 3 and the second impactor 4 do not emit mechanical pulses.

[0032] Step 5: When the sparring partner hits the ball that the trainee has returned to the court again, repeat the above steps until the training ends; if the ball goes into the net, out of bounds, or any other mistake occurs, the sparring partner will serve again.

[0033] In this embodiment, after anticipating the direction of the ball coming from the opposite court during the shot, the practitioner can more accurately grasp the appropriate timing for pulling back and swinging forward, thus providing assistance and correction for the tennis shot.

[0034] Specifically, both the training tennis ball 5 and the auxiliary device 2 are equipped with signal control switches. When the signal control switches are off, the operating circuits of both the training tennis ball 5 and the auxiliary device 2 are not operational. To facilitate charging of the internal battery of the training tennis ball 5, a wireless charging interface is provided on the training tennis ball 5.

[0035] See Figure 1 and Figure 2 To facilitate the fixing of the auxiliary device 2, a magic buckle 7 is provided on the auxiliary device 2. The auxiliary device 2 has a groove 8 that is adapted to the racket arm 1. A first impactor 3 and a second impactor 4 are respectively provided on both sides of the groove 8. When installing the auxiliary device 2, the groove 8 is locked onto the racket arm 1, and then the magic buckle 7 is tightened to securely install the auxiliary device 2 on the practitioner's racket arm 1 (upper arm).

[0036] See Figure 3 An impact ball 9 is installed inside the hollow cavity of the training tennis ball 5. A pressure sensor 6 is installed on the outer surface of the impact ball 9. A first controller is installed inside the impact ball 9. The first controller sends a wireless control signal to the signal receiver of the auxiliary device 2 through a signal transmitter. When the training tennis ball 5 comes into contact with the racket or the ground, the impact ball 9 collides with the training tennis ball 5, and the impact force is collected by the pressure sensor 6, which then generates a feedback signal to the first controller. In order to ensure that the impact force can be collected in a timely and accurate manner, multiple pressure sensors 6 are evenly arranged on the impact ball 9.

[0037] Regarding the reception, processing, and adjustment of signals for mishitting, mishitting can be mainly categorized into three types:

[0038] ① The ball hits the net: After the server or receiver touches the ball with their racket, the ball does not cross the net or bounces and falls above the net.

[0039] ② Hitting the ball out of bounds: The server or receiver hits the ball, and the tennis ball flies over the net but does not touch the ground, flies directly out of the baseline, doubles line, or even around the net;

[0040] ③ The ball touches the ground twice: The server or receiver hits the ball, and the tennis ball lands on the ground and bounces twice or more before it touches the net.

[0041] When a mishit occurs (mishit is not limited to the three situations mentioned above, but also includes any practice situation that the training partner deems necessary to reset the signal), the signal for the training tennis ball will be reset as follows:

[0042] See Figure 4 The tennis ball signal control switch 10 is a wireless control switch. An observer is added outside the court. When the observer observes a mishit, the observer holds the tennis ball signal control switch and presses button B of the switch to cut off the working circuit of the tennis ball. The signal transmitter in the tennis ball is reset to standby mode. At this time, even if the tennis ball is hit, the internal signal generator will not transmit a signal to the auxiliary equipment, and the auxiliary equipment will not work. When the working circuit of the tennis ball needs to be activated, simply press button A of the switch to reconnect the circuit. The training partner can then serve again and follow the above steps for training.
