Description

An intelligent tennis ball server for physical education teaching

technical field

The utility model relates to the technical field of tennis ball servers, in particular to an intelligent tennis ball server for physical education teaching.

Background technique

Tennis is a kind of ball game, usually played between two singles players or two pairs. Players hit the tennis ball with a tennis racket across the net on the tennis court, in order to allow novices to quickly master the basic tennis style , and to train the players, a tennis ball server will be used. The tennis ball server is a machine that automatically serves the ball when playing tennis. Through the ball outlet, two wheels can be seen, that is, the two wheels driven by the motor squeeze the ball out through rapid rotation, and the different rotation speeds of the upper and lower wheels can squeeze the ball out. The topspin or backspin can be adjusted, and the tennis ball will not be crushed. However, the instructions of the server recommend the use of training balls. This kind of ball has a thick tire, is not easy to leak, and is more durable.

The existing tennis ball launcher is only provided with two wheels, so that the existing ball server can only serve at a fixed point, and the ball sent from one position will be very dull, so that the teaching effect is low. When used in outdoor tennis courts, Because there is no socket, the power supply remains unchanged, and the electric energy of the storage battery will be exhausted after a short period of time, so that the service time of the ball server is relatively short. Fully realize the teaching function.

Detailed ways

Please refer to Fig. 1-3, in the embodiment of the present utility model, a kind of intelligent tennis server for physical education, comprises ball case 1, and the upper left side of ball case 1 is provided with ball bucket 2, and the right side of ball case 1 is provided with There is a tee opening 3, the lower end of the ball box 1 is provided with a base 4, the lower side of the base 4 is provided with four moving wheels 5, the upper side of the base 4 is provided with a handle 6, and the lower end of the base 4 is equipped with four hydraulic rods 7 (the model is Y-HG1), the upper end of ball box 1 is provided with first solar panel 14 and second solar panel 21, the inboard of moving wheel 5 is provided with turning bar 8, and the middle part of turning bar 8 is fixedly installed with driven wheel 9, The lower side of the base 4 is fixedly equipped with a first motor 10 (the model is VTB56-2A), the output end of the first motor 10 is connected with a first driving wheel 11, and the first driving wheel 11 is meshed with the driven wheel 9 to connect the tennis ball. Put the ball bucket 2 into the inside of the ball box 1, and hit the tennis ball at high speed through the service opening 3. After the first motor 10 starts, it drives the first driving wheel 11 to rotate, and the first driving wheel 11 drives the driven wheel 9 and the rotating rod 8 to rotate. , so that the moving wheel 5 on the lower side of the base 4 rotates, the operator can move the position of the device after holding the handle 6, and the first motor 10 is used to realize the electric power-assisted effect, so that the operator does not need to manually push the device to carry out Move, reducing the labor intensity of the operator, when the ball server is serving on the court, different service positions can be preset, so that the first motor 10 drives the ball server to serve in different positions, so that The position of serving the ball is changeable, so that the angle of serving the ball can be more imitated by a real person, so that the training effect is better. When the device reaches the designated place, the hydraulic rod 7 moves downward to lift the ball server, so that the moving wheel 5 is no longer in contact with the ball. Ground contact, which enhances the stability of the device, also increases wind resistance.

The right side of ball box 1 is provided with display screen 12, and the lower side of display screen 12 is provided with loudspeaker 13, and display screen 12 can play the teaching video of some tennis and the tennis action that needs to learn, and loudspeaker 13 can play the sound when explaining video, Thereby making this ball server realize unmanned teaching, make the effect of teaching better.

The upper end of the first solar panel 14 is horizontally equipped with two slide bars 15, the upper end of the slide bar 15 is provided with a slide rail 16, the right side of the slide rail 16 is provided with a rack 17, and a slide block 18 is slidably installed in the slide rail 16, The right end of slide block 18 is fixedly installed with second motor 19 (the model is VTB56-2A), and second solar panel 21 is fixedly installed on the upper end of slide block 18, and the output end of second motor 19 is connected with second drive wheel 20, the second The two drive wheels 20 are meshed with the rack 17, and a storage battery 23 is arranged between the lower end of the first solar panel 14 and the upper end of the ball box 1, and an inverter 22 (the model is 7556-NFA) is arranged on the left side of the storage battery 23. ), the second solar panel 21 positioned on the upper side absorbs the light energy and converts it into the required electric energy through the inverter 22 and stores it in the storage battery 23, thereby providing electric energy for the ball server. After the second motor 19 starts, it drives the second driving wheel 20 rotates on the upper side of the rack 17, the second driving wheel 20 drives the slider 18 to slide on the upper side of the slide rail 16, so that the upper second solar panel 21 is removed from the upper side of the first solar panel 14, Therefore, the area for absorbing light energy is enhanced, the absorbed light energy is increased, and the electric energy generated is increased, so that the working time of the ball server is prolonged.

The working principle of the utility model is as follows: tennis balls are put into the ball box 1 through the ball bucket 2, and the tennis balls are shot out at high speed through the service opening 3. After the first motor 10 is started, the first driving wheel 11 is driven to rotate, and the first driving wheel 11 drives the driven wheel 9 and the rotating rod 8 to rotate, so that the moving wheel 5 on the lower side of the base 4 rotates, and the operator can move the position of the device after holding the handle 6, and the first motor 10 is used to realize the electric power assist effect , so that there is no need for the operator to manually push the device to move, which reduces the labor intensity of the operator. When the ball server is serving the ball on the court, different service positions can be preset, so that the first motor 10 drives the ball. The ball server serves in different positions, so that the position of the ball can be changed, so that the angle of the ball can be imitated by a real person, so that the training effect is better. When the device reaches the designated place, the hydraulic rod 7 moves downward, and the ball server Jack up, so that the mobile wheel 5 is no longer in contact with the ground, thereby enhancing the stability of the device, and also enhances the wind resistance. The display screen 12 can play some tennis teaching videos and tennis moves that need to be learned, and the speaker 13 can play. The sound when explaining the video makes the server realize unmanned teaching, which makes the teaching effect better. The second solar panel 21 on the upper side absorbs light energy and converts it into the required electric energy through the inverter 22 and stores it in the In the storage battery 23, thereby provide electric energy for the ball server, after the second motor 19 starts, the second driving wheel 20 is driven to rotate on the upper side of the rack 17, and the second driving wheel 20 drives the slider 18 to slide on the upper side of the slide rail 16, Thereby the second solar panel 21 on the upper side is removed from the upper side of the first solar panel 14, thereby enhancing the area for absorbing light energy, so that the absorbed light energy increases and the electric energy generated increases, so that the working time of the ball server is increased. extend.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Any equivalent replacement or change of the technical solution of the utility model and the concept of the utility model shall be covered by the protection scope of the utility model.
