Abstract

The invention belongs to the technical field of tennis ball sports equipment, and particularly relates to a tennis ball serving device which comprises a ball serving machine and a controller. The controller is installed on the outer side of the ball serving machine, and the controller is used for controlling the device to operate automatically; the ball serving machine comprises a shell, a ball serving launching device, a lifting unit and a ball inlet channel, the upper end of the shell is a slope, one side of the shell is provided with the ball inlet channel, and the lifting unit is located inside the shell; the ball inlet channel is arranged obliquely, and the lower end of the ball inlet channel makes contact with the end of a stretchable cylinder; the lifting unit comprises a stretchable cylinder and a weight sensor; the lifting unit is used for pushing tennis balls in the ball inlet channel out of the shell; the ball serving launching device is located at the upper end face of theshell; table tennis are launched by means of elasticity of a rubber sheet, the tennis ball serving initial speed is increased, a rubber sheet is driven through the sliding shaft to slide in an arc shape, and therefore the tennis serving angle can be regulated and the tennis serving randomness can be enhanced, and the tennis training effect is improved.

Description

technical field [0001] The invention belongs to the technical field of tennis equipment, in particular to a tennis ball serving device. Background technique [0002] In tennis training, it is the most commonly used method in tennis training that the coach continuously feeds the ball and the players return the ball continuously. This method not only consumes a lot of physical strength of the coach, but also cannot track the speed and trajectory of the ball, making it difficult to Make a scientific judgment on the accuracy and stability of serving. As a training auxiliary equipment, the tennis ball machine can continuously, stably and accurately serve the players to achieve the purpose of scientific and precise training. [0003] Its serving principle of the tennis ball serving machine of the prior art is the friction wheel serving, and the friction wheel ball serving machine adopts the principle of double-wheel counter-rotation extruding and rubbing the ball to serve. The e...
