Description

A sports equipment serving spin adjustment module

technical field

The invention relates to the field of serving training equipment, in particular to a serving spin adjustment module of sports equipment.

Background technique

Publication number: CN107050799A The invention patent discloses a football long-passing and serving machine. A football long-passing and serving machine is disclosed, which includes a base, a serving mechanism, a ball storage bin, an azimuth turntable and a first hydraulic cylinder; wherein the serving mechanism includes a serving mechanism. The channel, the second hydraulic cylinder, the spring, the ball stopper, the steering gear, the tee shot block and the pressure sensor arranged on the tee block; the front end of the azimuth turntable is also provided with an infrared rangefinder; the azimuth turntable is also provided with a microprocessor The microprocessor is connected with the remote control wireless signal through the wireless communication module. The disadvantages of this design are: it is impossible to generate a spinning ball, but the actual training is that it is very necessary to serve the spinning ball. It is one of the basic purposes of training to train players to respond to the spinning ball in a timely manner. Different ball trajectory effects. When the ball flies forward without rotating, the velocity of air flowing backwards on the upper, lower, left and left surfaces of the ball is equal. If the sphere itself rotates upwards, it will drive the air on the upper part of the sphere to flow forward, which will conflict with the air flowing backwards, so that the air velocity on the upper part of the sphere decreases and the pressure increases; while the upward rotation of the sphere drives the sphere The air in the lower part flows backwards, in the same direction as the air flowing backwards, increasing the air velocity and decreasing the pressure in the lower part of the ball. In this way, due to the large pressure on the upper part of the ball and the small pressure on the lower part, the ball is quickly pressed down in flight, forming a descending parabola trajectory. The faster the spin, the faster the descent. In the same way, the underspin ball is flying up, and the side spin ball is tilted to the side. The hit ball cannot be rotated, which is very different from the actual serving effect, so it cannot be adapted to high-quality training effects.
