Self-help tennis service training device based on unmanned partner training

Abstract

The invention provides a self-help tennis service training device based on unmanned partner training. The self-help tennis service training device comprises a square bottom plate, a leaf spring and aremote controller, wherein a square top plate is arranged right above the square bottom plate; the square top plate and the square bottom plate are fixedly connected by virtue of a group of hydraulicscissors mechanisms. When intercept back training operations of smash need to be trained, training personnel transmit instructions to a single-chip by the remote controller, the single-chip controls the hydraulic scissors mechanisms to extend and ascend, and the two groups of telescopic hydraulic cylinder pistons are controlled to ascend, so that the square plate rotates along two U-shaped connecting plates via a U-shaped connecting block. Therefore, a cylindrical groove of the square plate corresponds to an area in which the training personnel in the tennis court are positioned after ascending. According to the training device disclosed by the invention, the tennis ball ejecting from the cylindrical groove can serve as the smash so as to train the intercept back training operations of thesmash of the training personnel.

Description

technical field [0001] The invention belongs to the technical field of tennis training and sports equipment, and more specifically relates to a tennis self-serve training device based on unmanned training. Background technique [0002] Sports training requires repetitive practice, especially for some unskilled movements of athletes; the same is true for tennis training. In addition to sparring, repetitive practice of catching the ball in various situations is essential. Artificial serving by sparring is not only poor in repeatability, but also less efficient. In addition, athletes cannot train individually without sparring. [0003] The tennis ball machine can act as a training partner, but the current tennis ball machine has the following deficiencies in use: [0004] 1. The existing tennis ball machine cannot launch a smash ball, which leads to the lack of training operations for intercepting and counterattacking the smash ball during individual training; [0005] 2. The...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a tennis self-service training device based on unmanned training, to solve the problem that the existing tennis ball machine cannot launch the smash ball, resulting in the lack of interception and counterattack of the smash ball when the athlete is training alone. The training operation and the existing tennis ball machine are all a tennis ball launching port, and the tennis ball launching position is fixed, which leads to the lack of unknown sense of the tennis ball serving position when the athlete is training alone, and there is no mutation, which leads to the inability to train the player's adaptability. question
