Problems solved by technology

[0002] Tennis is a sports ball game in our country. Usually, two players team up to practice together during training. You can also see a variety of tennis training devices in the market, but these training machines usually send out when they are in use. The ball has no form of rotation, and most of them are linear. It is more suitable for novice athletes to use similar trainers to train, but for athletes who have advanced skills, they will encounter various side spin balls in the game. Sometimes there will be some angular deviation on the original

Abstract

The invention discloses a tennis ball launcher. The tennis ball launcher comprises a ball barrel with an upper opening and a lower opening, a ball outlet motor and a ball outlet pipe located at a bottom end of the ball barrel and communicated with the ball barrel, wherein an inner wall of one end of the ball outlet pipe is in threaded connection with a ball outlet rod, a sliding block is slidably connected into an inner cavity of the ball outlet rod, and the other end of the sliding block is fixedly connected with an output shaft of the ball outlet motor; one side end of the ball outlet pipe is connected with a ball serving mechanism, an outer wall of the upper end of the fixing block is connected with a rotating motor, an output shaft of the rotating motor longitudinally penetrates through the fixing block and then is fixedly connected with a handle of the tennis racket, a lower end of the ball serving motor is connected with a lifting mechanism, and a bottom end of the lifting mechanism is connected with a triangular supporting seat; a central information processor and a remote receiving device are arranged at the top end of the triangular supporting seat, and a movement mechanism is connected to a bottom end of the triangular supporting seat. Through cooperation of the ball outlet mechanism and the ball serving mechanism, the tennis racket rotates at a constant speed in a reciprocating mode, the angle position of the tennis racket is changed through the racket rotating motor, and therefore the ball serving torque and the rotating torque are changed.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a tennis ball launcher. Background technique [0002] Tennis is a sports ball game in our country. Usually, two players team up to practice together during training. You can also see a variety of tennis training devices in the market, but these training machines usually send out when they are in use. The ball has no form of rotation, and most of them are linear. It is more suitable for novice athletes to use similar trainers to train, but for athletes who have advanced skills, they will encounter various side spin balls in the game. Sometimes there will be some angular deviation on the original trajectory due to its own rotational torque, and the athlete will make a correct judgment on the deflection position of the side spin ball based on the experience during normal training; secondly, the situation on the field changes rapidly during the game , the athlete not only makes a jud...
