An automatic serving device for sports tennis

Abstract

An automatic ball-serving device for sports tennis, comprising a main body, vertical boards are fixedly installed on both sides of the main body, and the tops of the vertical boards are respectively rotated and connected to movable boards, and a limit mechanism is also provided between each vertical board and the corresponding movable board to limit The position mechanism can limit the rotation of the movable plate. The movable plates are all U-shaped structures. There are slide plates inside the movable plates. The slide plates are respectively connected with the corresponding movable plates through the first telescopic rods. Both the telescopic rod and the movable rod of the second telescopic rod are hollow structures. The single-chip microcomputer control system can randomly retrieve a tangent angle from the data storage module, and the tangent angle can be stretched to different lengths through the second telescopic rod. When the tennis ball contacts the elastic plate, the trajectory of the tennis ball changes, which greatly improves the performance It has the disadvantage of a single technical serving route, and the two elastic boards can be alternately tangent to the tennis ball, which can further enrich the movement track of the tennis ball, and is more suitable for tennis players to use in single-person training.

Description

technical field [0001] The invention belongs to the field of tennis training, in particular to an automatic serving device for sports tennis.
