Embodiment 1: The embodiment of the present invention discloses a tennis trainer, the working principle is as follows:

According to the training needs, fix the bracket 1 at the proper position of the tennis training ground 10, and after fixing the ball machine 3, the inductive rebound board 4 and the support frame 5, etc., operate the controller to make the controller control the two motors 2 to synchronize movement, so that the two motors 2 correspond one by one to drive the corresponding turntable 11 to rotate through the two gears 2, and then each turntable 11 drives the corresponding ball machine 3 to rotate, so that the path of the ball launching tennis balls on the two ball machines 3 is the same. One corresponds to the two sidelines 101. In this state, the controller controls the action of the first serving machine 3 to start serving the ball, and then the remote player receives the ball and then moves the ball along the corresponding diagonal of the second serving machine 3. The line 103 hits the second induction rebound board 42 corresponding to the diagonal line 103. When the second induction rebound board 42 senses the ball, the sensing information is sent to the controller, and the controller will control the second ball machine 3 Start the action of serving, then the player needs to run from the upper sideline 101 to the sideline 101 on the other side to receive the ball launched by the second serving machine 3, and then the long-distance player receives the ball and moves the ball along the first serving machine 3 The corresponding diagonal line 103 hits the second induction rebound board 42 corresponding to the diagonal line 103. When the second induction rebound board 42 senses the ball, it will send the sensing information to the controller, and the controller will control The first ball machine 3 starts the action of serving, so repeatedly, in the process of playing rounds between the player and the two ball machines 3, the path of the ball is "8" shape, so that the player can complete each shot independently A drive drill that runs from one side of the baseline to the other.

According to training needs, operate the controller so that the controller controls the two motors 2 to move synchronously, so that the two motors 2 drive the corresponding turntable 11 to rotate through the two gears 2 one by one, and each turntable 11 drives the corresponding ball machine 3 Rotate, make the path that the serving port on the two serving machines 3 launch tennis one-to-one correspondence along two diagonals 103, in this state, controller controls wherein first serving machine 3 starts the action of serving, then far away Mobilize after receiving this ball and strike the ball along the sideline 101 corresponding to the second serving machine 3 onto the first induction rebound board 41 corresponding to the sideline 101, when the first induction rebound board 41 senses the ball, the induction information Send it to the controller, then the controller will control the action of the second serving machine 3 to start serving, then the player needs to run from the upper sideline 101 to the sideline 101 on the other side to catch the ball launched by the second serving machine 3, and then After receiving the ball, the player hits the ball along the sideline 101 corresponding to the second serving machine 3 onto the first induction rebound board 41 corresponding to the sideline 101. When the first induction rebound board 41 senses the ball, it will sense the ball. If the information is sent to the controller, the controller will control the action of the first serving machine 3 to start serving the ball, and so on and on, so that the path of the ball during the round between the player and the two serving machines 3 will be in the shape of an "8" , so that the athlete can complete the pumping training that runs from one side of the bottom line to the other side every time the ball is hit.
