Tennis training device

Abstract

The invention discloses a tennis training device. The tennis training device comprises an air outlet hole, an air inlet hole capable of forming air circulation with the air outlet hole, an air jet head arranged in a tennis ball, an inner shell arranged in the center of the tennis ball; a gyroscope is arranged on the surface of the inner shell, and a central processing unit, a power source and a positioner used for detecting the position of the tennis ball are arranged in the inner shell. The central processing unit is used for receiving the real-time position, detected by the positioner, of the tennis ball in real time, generating the future position where the tennis ball is about to reach according to the real-time position of the tennis ball, and controlling the jet heads in the corresponding directions to work according to the directions of the real-time position and the future position and the tennis ball state detected by the gyroscope, so that the tennis ball moves from a real-time position to a future position under the pushing of the gas. By improving the interior of the tennis ball, the tennis ball can freely fly in a training field, and when the tennis ball makes contact with a tennis racket, the tennis ball is adjusted to be normal, so that the tennis ball can freely fly again after falling to the ground.

Description

technical field [0001] The invention relates to the field of tennis training equipment, in particular to a tennis training device. Background technique [0002] In the training process of tennis, the training of catching the ball is exactly a very important training process. When playing the ball, receive the ball in various spatial positions. At present, in the prior art, some tennis ball machines are used to launch tennis balls, which generally cause tennis ball machines to launch tennis balls at different positions, so that the trainer can catch the ball. It makes different plans to serve the ball, but due to the setting of the launching angle and launching force of the serving machine, it will make the trainer very clear about the trajectory of the tennis ball and the position where it will reach after many times of training. Can make trainer produce certain experience, be unfavorable for training, simultaneously, such training mode needs a large amount of tennis balls...

Problems solved by technology

At present, in the prior art, some tennis ball machines are used to launch tennis balls, which generally cause tennis ball machines to launch tennis balls at different positions, so that the trainer can catch the ball. It makes different plans to serve the ball, but due to the setting of the launching angle and launching force of the serving machine, this will make the trainer very clear about the trajectory of the tennis ball and the position it will reach after many times of training. It will make the trainer have a certain experience, which is not conducive to training. At the same time, such a training method requires a lot of tennis balls to ensure continuous training. Otherwise, it is necessary to recycle and collect tennis balls, which is a waste of time.
