[0050] Advantages and effects of the present invention

[0051] 1. The table tennis training device for children and teenagers of the present invention has a rational overall structural design, clean and smooth appearance, easy installation, simple and convenient operation, strong safety, and high mobility, and can be moved freely according to training requirements.

[0052] 2. It features strong professional training techniques, diverse training methods, and strong interest. It is not only for the training of table tennis skills for teenagers and children, but also suitable for table tennis enthusiasts of other age groups.

[0053] 3. By raising and lowering the uprights or sleeves, the speed, height, and landing point of the table tennis ball can be controlled and adjusted. Based on the speed, height, and landing point of the ball, the player can make accurate judgments, thereby enhancing their sense of the ball and improving their offensive awareness. Generally, during a match, the opponent's ball bounces higher than the net after hitting the table, with only a few balls below the net. However, because the ball is too close to the body, due to visual errors, players tend to think it is too low and are hesitant to attack, which can easily cause psychological pressure. By raising and lowering the uprights or sleeves, the ball's height below the net can be adjusted to various heights. Repeated low-ball attacking practice can help overcome this psychological barrier of not daring to attack, cultivate the habit of proactively attacking balls from the table and baseline, and strengthen their awareness of proactive attacking.

[0054] 4. Through the joint operation of the electromechanical rotating device and the sensing device, the frequency of table tennis balls is controlled and adjusted to increase the density and intensity of the practitioner's practice per unit time; the increase in the frequency of balls can enhance the sensitivity and adaptability of the trainees' technical movements; it is a very important practice method in the early stage of the practitioner's practice and in the subsequent intensive improvement stage.

[0055] 5. Through the combined action of the folding rotating direction-changing device and the baffle combination, the direction of the table tennis ball is controlled and adjusted, and the variability of the ball path direction is enhanced to adapt to the variability of the game situation. It can better deal with the ever-changing balls hit by the opponent during the game. It has a great promoting effect on improving the practitioner's body coordination, rationality of movement, accuracy of landing point judgment, and control of hitting the ball, so as to achieve the purpose of movement technology training.

[0056] 6. The baffle assembly and the sensing device work together, and practitioners can practice various single or combined technical exercises such as barehand movement exercises, walking exercises, racket swing exercises, speed exercises, or combining hitting with barehand movement, hitting with walking movements, hitting with speed exercises, etc., which can further strengthen and master forehand attacking techniques, deepen the understanding of forehand attacking techniques, and improve the ability to apply forehand attacking techniques in actual combat.

[0057] Design principle and usage of the present invention

[0058] 1. It is designed based on the integration of the physiological characteristics of children and adolescents, the technical characteristics of table tennis games, and the modern artistic aesthetics of adolescents.

[0059] 2. Based on the principle of mutual conversion of kinetic energy and potential energy in physics, the weight of the table tennis ball is utilized, and the lifting and lowering of the column and the sleeve are coordinated to achieve the required speed of the ball to meet the training requirements.

[0060] 3. Based on the fact that the balls hit by the opponent in the game are varied, that is, the situation on the field is highly variable, a set of folding rotation direction-changing devices and baffles are designed through all-round integration through lifting and lowering in the up and down directions and rotating in the left and right directions. This can change the route of the table tennis ball and the direction of the ball, so as to achieve the purpose of training technology.

[0061] 4. Based on physiology and sports myology, a comprehensive analysis of the physical physiology and table tennis technical training characteristics of adolescents and children is conducted. Using the multiple combination design of the two sensor functions, training in single and combined techniques such as barehand movement exercises, walking exercises, racket swinging exercises, speed exercises, or combining hitting with barehand movement, hitting with walking movements, and hitting with speed exercises is completed to further strengthen and master forehand attacking techniques and improve the ability to apply them in actual combat.

[0062] 5. The working principle of the operating panel device is: the processor receives the data transmitted by the sensor and the instructions of the function buttons, calls the chip to process and calculate the data, and the processor sends the processed data and instructions to the electromechanical rotating device and display screen for operation and display.

[0063] Instructions for use: A coach or trainee holds the push and pull handles to push and pull the table tennis training device for children and teenagers of the present invention to a position required for training, connects to an AC power source or activates the lithium battery switch button as needed, and fills the ball storage funnel with pre-prepared table tennis balls through the upper opening of the funnel. The coach raises or lowers the upright column or sleeve according to training requirements, holds the slide tube with his left hand and slides it upward or downward along the ball outlet tube, and simultaneously holds the folding rod III with his right hand to fold it in coordination with the left hand movement, and adjusts the inclination of the ball outlet tube to the table tennis ball running route required for training; rotates or folds the baffle to adjust the table tennis ball outlet direction required for training, and activates the corresponding button I, button II, button III or button IV according to different training purposes, and then training can begin; in order to better enhance the sensitivity and adaptability of the trainee's technical movements, the coach holds the rotating handle and rotates it left and right according to the on-site situation, and changes the ball outlet direction again according to the scene.
