Multifunctional three-wheel ball serving machine

Abstract

The invention discloses a multifunctional three-wheel ball serving machine, which comprises a master control module, a launching mechanism, an angle regulating mechanism and a storage mechanism, wherein the launching mechanism is connected to the angle regulating mechanism and the storage mechanism; the launching mechanism, the angle regulating mechanism and the storage mechanism are connected tothe master control module; the launching mechanism comprises a first ball serving wheel, a second ball serving wheel and a third ball serving wheel which are mutually independent in rotating speed; the first ball serving wheel, the second ball serving wheel and the third ball serving wheel are arranged in a pin-shaped form (a Chinese character, pin), so that a ball serving passage from which ballsare launched is defined; and the first ball serving wheel, the second ball serving wheel and the third ball serving wheel are used for squeezing and rubbing the balls by rotating speeds which are mutually different, so that the balls are launched in different ball serving modes. According to the multifunctional three-wheel ball serving machine provided by the invention, conventional fixed-point ball serving can be achieved, and in addition, such functions as launching leftwards and rightwards rotating balls, random ball, side-rotating balls, high-pressure balls and the like can be achieved; therefore, user's training requirement can be satisfied.

Description

technical field [0001] The invention relates to the field of serving machines, in particular to a multifunctional three-wheel serving machine. Background technique [0002] Tennis, as a classic ball game, is usually played in the form of two-person sparring or four-player sparring. This competition system requires more than two people to participate in the game. Therefore, in order to satisfy the single player In order to meet the needs of training, auxiliary training equipment such as tennis ball machines have appeared on the market, which solves the embarrassment that a single person cannot complete tennis. [0003] But the serving mode of existing ball machine is relatively single, generally only can realize fixed-point serve, and can't realize the functional balls such as side spin ball, high pressure ball, therefore can't satisfy the training requirement of user. Even if some existing ball machines can change the direction or angle of the ball, this is only limited to ...

AI Technical Summary

Problems solved by technology

[0003] However, the serving method of the existing ball machine is relatively simple, and generally only can realize fixed-point serve, but cannot realize side spin ball, high-pressure ball and other functional balls, so it cannot meet the training requirements of users

Even if some existing ball machines can change the direction or angle of the ball, this is only limited to the angle adjustment in the plane direction, and it is also impossible to achieve high-quality balls such as side spin balls and high-pressure balls, thereby failing to meet the user's training.
