Problems solved by technology

At present, in the process of tennis training, the trainer is all about hitting the ball on the training ground. During the practice, the trainer can't always know the flight state of the tennis ball after he hits the ball, he can only roughly When the coach is not there, the trainer will train blindly by himself, so will greatly reduce the training effect

Embodiment 1

[0026] This embodiment provides a tennis training device, and the present invention is implemented through the basic necessary technical features to solve the problems raised in the technical background section of this application document.

[0027] Specifically, such as figure 1 As shown, the embodiment of the present invention provides a tennis training device, which includes a tennis flannel layer 1 and a rubber layer 8 inside the flannel layer 1. In the existing tennis ball, the outer layer is a flange The fleece layer 1 and the inner rubber body of the flannel layer 1 are just solid rubber bodies. In the present invention, the outer surface of the rubber layer 8 is closely provided with several pressure sensors 2, and the flannel layer 1 and the The pressure sensor 2 is bonded. In this way, the pressure sensor 2 can detect the pressure at various points on the surface of the flannel layer 1 during the tennis ball movement.

[0028] The rubber layer 8 is provided with an...

Embodiment 2

[0032] This example is based on Example 1 and optimizes the implementation in Example 1, so that this example is more stable and has better performance during operation, but it is not limited to the one described in this example implementation.

[0033] Specifically, such as figure 2 As shown, in this embodiment, the tennis ball is provided with an inflation hole 13 for inflating the rubber layer 8, and the inflation hole 13 runs through the flannel layer 1 and the rubber layer 8, so The sealing surface of the inflation hole 13 is kept smooth with the flannel layer 1, and the sealing surface of the inflation hole 13 is provided with flannel.

[0034] Since the acceleration sensor 10, the gyroscope sensor 10, the wireless communication module 6, the central processing unit and the power supply unit 5 are arranged in the rubber layer 8, the rubber layer 8 of the present invention is provided with a hollow structure, which can effectively ensure that each electronic For the no...

Embodiment 3

[0039] This example is based on Example 1 and optimizes the implementation in Example 1, so that this example is more stable and has better performance during operation, but it is not limited to the one described in this example implementation.

[0040] Specifically, such as Figure 2-3 As shown, in this embodiment, a connection block 11 is provided at the center of the tennis ball, and the surface of the connection block 11 is evenly connected with several connecting rods 3, and one end of the connecting rod 3 is connected to the surface of the connection block 11, The other end of the connecting rod 3 is connected to the rubber layer 8 , and the gyro sensor 10 is arranged at any position on any one of the connecting rods 3 .

[0041] It has been described in Embodiment 1 that the gyro sensor 10 is not arranged at the ball center of the tennis ball, and the ball center of the current tennis ball is provided with a connecting block 11, and the connecting block 11 connects the...

Abstract

The invention discloses a tennis training device which comprises a flannel layer of a tennis ball and a rubber layer located in the flannel layer, a plurality of pressure sensors are closely arrangedon the outer side face of the rubber layer, and the flannel layer is attached to the pressure sensors. An acceleration sensor, a gyroscope sensor, a wireless communication module, a central processingunit and a power supply device are arranged in the rubber layer, the gyroscope sensor is located at the non-sphere center of the tennis ball, and the central processing unit is in signal connection with the acceleration sensor, the gyroscope sensor and the wireless communication module. According to the tennis ball, the ball body of the tennis ball is improved; therefore, the tennis ball can automatically detect the real-time flight state of the tennis ball; the ball hitting condition of a trainee is obtained by combining with the magnitude of the contact force when the ball is hit, and the data is transmitted to the display through the wireless communication module, so that the trainee can know the ball hitting condition of himself / herself according to the real-time data when a coach isabsent.

Description

technical field [0001] The invention relates to the field of tennis training, in particular to a tennis training device. Background technique [0002] In the training of tennis, it is usually necessary to monitor the three-dimensional size of the trainer when hitting the ball and the flight state of the tennis ball after being hit, so as to judge the state of the trainer hitting the tennis ball, so as to carry out the training on the trainer's hitting Guidance and training. At present, in the process of tennis training, the trainer is all about hitting the ball on the training ground. During the practice, the trainer can't always know the flight state of the tennis ball after he hits the ball, he can only roughly When the coach is not there, the trainer will train blindly by himself, so It will greatly reduce the training effect. Contents of the invention [0003] The object of the present invention is to overcome the problems existing in the above-mentioned prior art, ...
