A robot tennis ball serving device

Abstract

The invention relates to a robot tennis serving device, which consists of a helicoid casing, a motor, a cow horn type funnel, a support frame and a transmission rod, wherein the helicoid casing is connected with the motor and the cow horn type funnel through rivets, the support frame is connected with the motor and the cow horn type funnel through a support shaft, the motor is connected with the support frame through rivets, one end of the transmission rod is connected with the support frame through an eccentric shaft, and the other end of the transmission rod is connected with the helicoid casing through a small shaft. The robot tennis serving device has the advantages that the structure is simple, reasonable and novel, the operation is simple and convenient, the robot tennis serving device can replace tennis training partners to realize partner training, the training effect can also be improved, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a tennis training equipment. Background technique [0002] Tennis trainer mainly contains following several forms at present, single-wheeled tennis ball machine, mobile tennis trainer, a kind of serve device that is applicable to tennis training. Single-wheel tennis ball machine, simple in structure, low in cost, controlled by computer, free from ball jamming, adjustable in serving speed, but not able to move the serving ball automatically, nor adjust the serving direction, although the adjustable serving speed, relying on a single friction wheel Serving, the speed of serving is poorly controlled, the ball path and landing point are also difficult to control, the training difficulty is low and cannot be improved, it can only be applied to simple training actions, and the practicability is poor; the mobile tennis trainer is easy to use and can be used for mobile use.

Single-wheel tennis ball machine, simple in structure, low in cost, controlled by computer, free from ball jamming, adjustable in serving speed, but not able to move the serving ball automatically, nor adjust the serving direction, although the adjustable serving speed, relying on a single friction wheel Serving, the speed of serving is poorly controlled, the ball path and landing point are also difficult to control, the training difficulty is low and cannot be improved, it can only be applied to simple training actions, and the practicability is poor; the mobile tennis trainer is easy to use and can be used for mobile use. The speed is adjustable, the landing point is stable, and the production cost is low, but it cannot automatically move the serve, nor can it automatically adjust the direction of the serve. Although the serve speed can be adjusted and it can be used for mobile use, it is difficult to achieve difficult training movements. Difficult to control, low degree of automation, poor sensitivity, which is not conducive to the improvement of skills; a serving device suitable for tennis training, simple in structure, safe and reliable, low in cost, simple in operation, but it cannot simulate the movement of the training partner to serve the ball, although it rotates The shaft is installed in the casing and can move up and down relative to the casing, and can also rotate 360°, but it cannot automatically adjust the shooting angle, and the rotation shaft is connected to the barrel and cannot rotate, and there is no power mechanism to drive and adjust the shooting direction and rotation. It can be operated by people and rotated by using directional casters around the base. The degree of automation is low, the randomness is poor, the training difficulty is low, and it is difficult for athletes to improve their training skills. The switch is difficult to control the number of servings each time, and it cannot simulate the serving action of the sparring partner, which directly affects the skill improvement of the trainers
