Badminton racket is a kind of high-explosive sports equipment. Its characteristics are: the amount of material used is small, the net pressure and tension of the racket frame are relatively high, and the deformation of the middle tube is relatively large when hitting the ball. In the development of high-performance badminton rackets, world-renowned brands expect to make breakthroughs in production technology and structural design in order to lead the market.

The structure of the badminton racket includes three parts: a head frame, a middle tube and a handle, wherein the head frame is connected to one end of the middle tube, and the handle is connected to the other end of the middle tube. The disadvantages of current rackets on the market are:

1. Generally, badminton rackets are made of carbon fiber and metal (metal materials such as titanium, aluminum alloy, pure iron, pure aluminum, etc.). Carbon fiber rackets are characterized by strong rigidity and poor torsion; metal rackets are characterized by strong torsion and poor rigidity, and both materials have their own shortcomings. How to reasonably combine the two materials so that the racket can combine the advantages of the two materials is one of the problems to be solved in the industry.

2. The key to the badminton game is the smashing part. In addition to swinging the arm to accelerate the shuttlecock, the smashing must be coupled with the wrist spike to make the ball fall in front of the net at a greater angle. , so the torque is relatively small, and if the torque is too small, it will not be enough to affect the landing point of the ball. At this time, the ball may fall out of bounds due to the small angle. Therefore, how to improve the bending turning point of the middle tube of the badminton racket to change the length of the moment arm, adjust the hitting angle and speed, and improve the power of smashing the ball is the second problem that the industry needs to solve.

Inside slot 22. As shown in FIG. 3 , the outer diameter of the metal reinforcing sleeve 21 may be equal to the outer diameter of the middle tube 20 to make a smooth transition between the two. As shown in FIG. 4 , the outer diameter of the metal reinforcing sleeve 21 may also be smaller than the outer diameter of the middle pipe 20 , leaving a space for the installation of the three-way connector of the head frame 10 . It should be noted that the length of the metal reinforcing sleeve 21 is much larger than its diameter, and it is a non-circular sleeve.

In this embodiment, the middle pipe 20 is made of carbon fiber material, and the metal reinforcing sleeve 21 is made of hard metal, such as titanium metal. By setting the metal reinforcing sleeve 21 on the middle tube 20 of the carbon fiber, the strong rigidity of the carbon fiber and the strong torsion of the metal reinforcing sleeve 21 can be advantageously combined, so that the racket combines the advantages of the two into one All in one, easy to use.

In addition, this design can also change the moment arm length of the middle tube 20. As shown in FIG. Strong, does not have the characteristics of deformation, and the lower end B→C of the middle tube 20 retains the original deformation characteristics, undoubtedly makes the bending turning point Q1 of the middle tube 20 in the middle of B and C when smashing the ball, compared with the conventional racket, the conventional racket The bending turning point of the racket is located at the middle point of the middle tube 20, and the bending turning point Q1 of the racket is moved down, which will increase the force arm of the middle tube 20, so that the pitch angle of the racket is different from that of the conventional racket, and the strength of hitting the ball and The speed has changed.

When hitting the ball, the upper end G→H part of the middle tube 20 is not deformed, and the lower end I→J part is also not deformed. The deformed part falls between H→J, and the middle point of H→J is the bending turning point Q3. Compared with the conventional racket, the bending turning point Q3 does not move up or down, but the moment arm of the racket is shortened, which can also achieve the effect of accelerating the speed of smashing the ball and increasing the strength.

Please refer to Fig. 8 to Fig. 10, which shows the specific structure of the fourth embodiment of the present invention, the difference between this material embodiment and the first embodiment is that a metal On the basis of the reinforcing sleeve 21, a built-in reinforcing member 23 is built in the lower end of the middle pipe 20 for connecting the handle 30, and the embedded reinforcing member 23 is embedded in the hollow structure of the middle pipe 20, as shown in Fig. 9 As shown, the embedded reinforcement 23 can be a solid column, as shown in FIG. 10 , or a hollow tube. The function of the embedded reinforcing member 23 is the same as that of the metal reinforcing sleeve 21 , both of which can enhance the torsion force of the middle pipe 20 and change the bending turning point of the middle pipe 20 .

Please refer to Fig. 11, which shows the specific structure of the fifth embodiment of the present utility model. The difference between this material embodiment and the fourth embodiment is that the metal reinforcement sleeve 21 and the embedded reinforcement 23 The installation position of the metal reinforcement sleeve 21 is set on the end of the middle tube 20 close to the handle 30, and the embedded reinforcement 23 is built in the end of the middle tube 20 close to the head frame 10.

Based on the above, the number of metal reinforcing sleeves 21 and embedded reinforcements 23 in this new embodiment is not limited to one or two, but three or more can be provided according to needs. And, the setting positions of the metal reinforcing sleeve 21 and the embedded reinforcement 23 are not limited to the upper end and the lower end of the middle pipe 20, but can be arranged at any position of the middle pipe 20. When there are multiple metal reinforcing sleeves 21, embedded When reinforcing member 23, can be set continuously or interval is set, to reach different smashing ball effects.

In summary, the key point of the design of the present invention is that since the middle pipe 20 is provided with a metal reinforcing sleeve 21, the middle pipe 20 is made of carbon fiber, and the reinforcing sleeve is made of metal, which can make the strong rigidity of the carbon fiber It is advantageously combined with the strong torsion force possessed by the metal reinforcing sleeve 21, so that the racket combines the advantages of the two into one, which is beneficial to use. In addition, the setting of the metal reinforcement sleeve 21 also changes the bending turning point and moment of the middle pipe 20, so that the middle pipe section corresponding to the metal reinforcement sleeve 21 does not bend when smashing the ball, and there is no middle pipe section of the metal reinforcement sleeve 21. The pipe section retains the original elastic deformation characteristics, so that the bending turning point can be moved up or down arbitrarily, changing the length of the racket's force arm, making the pitch angle of the racket different from that of the conventional racket, and changing the strength and speed of hitting the ball. When in use, the shorter the force arm, the faster the hitting speed and the greater the power, the faster the ball will land, the shorter the opponent's reaction time, and the higher the probability of not being able to catch the ball. Based on this, this design The racket can adjust the length of the force arm arbitrarily, and control the speed and strength of hitting the ball arbitrarily.
