Description

Technical Field

[0001] The utility model belongs to the technical field of sports training equipment, in particular to a tennis ball serving device. Background Art

[0002] A tennis server is a machine that can automatically serve a ball when playing tennis. Its operating principle mainly relies on the relative rotation of two wheels driven by a motor, which shoots the tennis ball by quickly squeezing it. This server can not only adjust the speed of the serve, but also generate adjustable topspin or backspin by controlling the different rotation speeds of the upper and lower wheels, thereby simulating a variety of serve types, such as side spin, straight ball, high lob, etc. There are many types of tennis servers, such as double-wheeled servers, portable tennis servers, pneumatic servers, and catapult servers. Each type has its own unique working principle and characteristics. When using a tennis server, it is recommended to use a training ball, because the ball tire of this ball is thicker, not easy to leak, and more durable. In addition, tennis servers are often equipped with computer remote control and remote sensing devices for speed measurement, which makes the operation of the server more accurate and convenient.

[0003] Publication number "CN218980393U" is an intermittent tennis ball server, belonging to the technical field of ball servers, including a support frame, a serving assembly is installed on the upper end of the support frame; the serving assembly includes a ball storage assembly, a rotating ball outlet assembly and a ball blocking member, the ball storage assembly is installed at the upper end of the support frame, the rotating ball outlet assembly is installed at one side of the ball storage assembly and the ball blocking member is connected to both the ball storage assembly and the rotating ball outlet assembly; the ball blocking member includes a gear lever, an L-shaped baffle plate and a guide plate; the L-shaped baffle plate is located on the outside of the edge tennis ball, the L-shaped baffle plate is fixedly connected with a gear lever, and the gear lever is located between the edge tennis ball and the sub-edge tennis ball. Through the above method, the utility model designs a purely mechanical intermittent tennis ball server, which can realize intermittent and continuous multiple serves when serving, and the serving is easy to control, and it can be realized that only one ball is served at a time, ensuring the user experience.

[0004] Although the above-mentioned utility model can realize intermittent continuous multiple serves, the serves are easy to control, and only one ball can be served at a time, thereby ensuring the user experience, but when in use, the user manually intervenes in the direction of the server, and it is difficult to ensure the accuracy and consistency of each adjustment through manual intervention. There may be slight differences in each adjustment, which may cause changes in the flight trajectory and landing point of the ball, thereby affecting the player's mastery and judgment of the technique. For players who need to accurately control the serve angle and landing point, this inconsistency may become an obstacle in training. At the same time, manual intervention not only interrupts the continuity and rhythm of training, but also greatly increases the time required for adjustment, thereby reducing the overall training efficiency. Utility Model Content
