Description

Badminton training racket

Technical Field

The invention belongs to the field of training equipment, and particularly relates to a training racket for a badminton sport project.

Background

Badminton is popular in China, a large number of badminton fans exist, and with the increase of the ball age, many badminton fans have urgent needs for improving the technical level, but many technical actions are difficult to master skillfully due to the absence of guidance of professional coaches. The high-distance ball technology is one of the most basic technical key fields in badminton, a batting person is required to exert force in a coordinated way to finally complete 'whipping' action, but when general badminton fans practice high-distance ball action, no professional coaches give guidance beside the badminton fans, whether own action is correct or not is difficult to judge, the improvement of the technical level is seriously hindered, wrong actions are possibly formed, and the later-stage correction is difficult.

At present, badminton fans mainly have two modes for training the high-distance badminton technology, one mode is a field training mode, namely two people pull high-distance badminton in opposite directions on a badminton court, or one person feeds the badminton and the other person to hit the badminton, the field training mode needs to be trained on a professional badminton court, and trainees are limited by fields and time; the second mode is a simulated hitting mode, for example, a cloth strip or a small ball is hung on a high place through a string and then hit through a racket, the training mode does not need a professional badminton court, but because the simulated hitting mode is a simulated hitting mode, the real flight track of the badminton cannot be seen, the hitting effect can be judged only through the sound after hitting the cloth strip, and if no coach is at the side, whether the technical action is accurate or not is difficult to judge, and the training is easy to be wrong. At present, no special training device for the badminton high-distance technology is available in the market, and therefore, a novel training racket needs to be provided to solve the problems.

Disclosure of Invention

The invention aims to provide a novel badminton training racket, which utilizes a cantilever type force sensor to judge the maximum force value of each swing of a batting person, when the batting person acts correctly and exerts force harmoniously, and the important idea of 'whipping' of a high-distance ball is realized, the maximum force value during swing is obviously improved, and then the maximum force value exerted by the batting person is compared with reference force value table data, so that the batting person can judge whether the own technical action is accurate and the swing technology of the batting person is in which horizontal level at present. Therefore, convenience is provided for badminton enthusiasts to independently practice technical actions, the technical actions can be corrected according to the change of the force value, the interest of the practicer is stimulated, and the practice effect is improved.

In order to achieve the purpose, the invention adopts the following technical scheme: a badminton training racket comprises a racket head, a racket rod and a racket handle, wherein the racket handle comprises a cantilever type force sensor, a signal processing circuit board, a liquid crystal display screen and a battery. The front end of the cantilever type force sensor is connected with the racket handle, when an exerciser quickly waves the racket, the stress of the racket head and the racket rod is transmitted to the cantilever type force sensor, then the stress is converted into force value information through the signal processing circuit board, and the stress peak value of each wave is displayed on the liquid crystal display screen.

The invention has the beneficial effects that: the practicers can intuitively realize the force variation caused by different swing action details by observing and comparing the swing force peak value of each swing, thereby being beneficial to continuously improving the technical action; and the force value of the swing can be compared with a standard reference swing force value table, the current technical level of the swing is recognized, the gap is searched, unreasonable details hidden in the technical action of the swing are found, the interest of training is aroused, and the training effect and the enthusiasm are improved.

Detailed Description

The invention is further described with reference to the accompanying drawings 1-3:

a badminton training racket is structurally shown in figure 1 and comprises a racket head 1, a racket rod 2 and a racket handle 4, wherein a cavity is formed in the racket handle 4, a cantilever type force sensor 5, a signal processing circuit board 7, a battery 8 and a liquid crystal display screen 10 are placed in the cavity, the racket rod 2 and the cantilever type force sensor 5 are connected together through a connector 3, 4 resistance type strain gauges 9 are pasted in the cantilever type force sensor 5 to form an equiarm bridge, and the cantilever type force sensor 5, the signal processing circuit board 7, the battery 8 and the liquid crystal display screen 10 are connected through a cable 6.

A badminton training racket has a handle rear cover structure as shown in figure 2, a rectangular hole is formed in a rear cover 11 of a racket handle 4, and a liquid crystal display screen 10 is installed on the rectangular hole and used for displaying the force value of a swinging racket.

In a preferred embodiment of the present invention, the working principle of the badminton training racket is as shown in fig. 3: after a practicer waves the racket, the force applied to the racket head 1 is transmitted to the cantilever type force sensor 5 through the racket rod 2 and the connector 3, the output voltage of the equal-arm bridge consisting of the resistance strain gauges 9 inside the racket changes, the output voltage is transmitted to the signal processing circuit board 7 through the cable 6, and the signal processing circuit board converts the output voltage into force value information after AD conversion and operation and displays the force value information through the liquid crystal display screen 10.
