Description

Technical Field

[0001] This utility model relates to the field of badminton racket technology, specifically a badminton racket with a special shaft. Background Technology

[0002] A badminton racket consists of a frame, handle, shaft, and the joint between the frame and shaft. The frame is the part that hits the shuttlecock and is usually made of lightweight, high-strength materials such as carbon fiber, titanium alloy, or aluminum alloy to ensure durability and flexibility. The handle is used for gripping and is usually designed to be ergonomic so that the player can control the racket stably. The shaft connects the frame and handle, and its length and stiffness directly affect the speed and power of the shot. Modern badminton rackets mainly use materials such as carbon fiber, titanium alloy, and aluminum alloy, which have high strength, lightweight, and good elasticity. In addition, the string tension of the badminton racket can be adjusted according to the player's needs to optimize the hitting effect.

[0003] In existing technologies, the shaft of traditional badminton rackets generally adopts a cylindrical structure, which has insufficient anti-torsion performance during high-speed shots. Due to the lack of sufficient support structure, the bottom of the shaft is prone to torsional deformation at the moment of impact, causing the racket face angle to shift, affecting the accuracy of the shot and the stability of control. In addition, the traditional cylindrical shaft takes a long time to recover to its initial state after deformation, and the deformation rebound speed is slow, resulting in a sluggish response during continuous shots, affecting the offensive rhythm and the quality of the return. At the same time, the cylindrical shaft has a small lateral moment of inertia and uneven force distribution, which easily leads to energy loss during high-intensity shots and reduces the initial velocity of the shot. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a badminton racket with a special shaft to solve the problem that the shaft of traditional badminton rackets generally adopts a cylindrical structure, which has insufficient anti-torsion performance when hitting the ball at high speed. Due to the lack of sufficient support structure, the bottom of the shaft is prone to torsional deformation at the moment of impact, causing the racket face angle to shift, affecting the accuracy of hitting the ball and the stability of ball control.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a badminton racket with a special central tube, including a frame, with multiple sets of net cables fixedly connected to the inner wall of the frame, two sets of connecting rods fixedly connected to the bottom end of the frame, and the two sets of connecting rods being arc-shaped, with connecting members fixedly connected to the bottom ends of the two sets of connecting rods, and a central tube fixedly connected to the bottom end of the connecting member, and the central tube having a hexagonal planar structure, with a honeycomb structure inside the central tube.

[0006] By adopting the above technical solution and using a honeycomb structure design, the racket shaft forms multi-directional support during impact, improving torsional strength, effectively reducing torsional deformation at the moment of impact, making the racket face angle more stable, improving control accuracy, and reducing unforced errors. The honeycomb structure has multiple cavities filled with first and second elastic balls, which buffer vibrations when subjected to impact, reducing the impact of high-frequency vibrations on the wrist. It also provides energy storage and release functions, accelerating deformation recovery and allowing the racket shaft to rebound to its initial state more quickly, improving the response speed of continuous shots and meeting the needs of high-speed offensive and defensive transitions. In addition to meeting the requirements, a fixing groove is set between the shaft and the grip to improve the overall rigidity of the shaft, optimize the energy transfer path, reduce energy loss during impact, increase the initial velocity of the shot, and enhance the durability of the shaft, reducing fatigue wear after prolonged use and extending the racket's lifespan. Through multiple optimizations such as honeycomb structure, shaft reinforcement, and elastic element cushioning, this utility model enables the racket to achieve higher torsional strength, faster rebound speed, and more stable shot control without increasing weight. It is suitable for high-level competition and professional training needs, providing badminton players with a better user experience.

[0007] Furthermore, the honeycomb structure includes a reinforcing tube, a reinforcing plate, a cavity, a first elastic ball, and a second elastic ball.

[0008] By adopting the above technical solution and using a honeycomb structure design, the central tube forms multi-directional support when hitting the ball, improving torsional strength and effectively reducing torsional deformation at the moment of impact.

[0009] Furthermore, the reinforcing tube is located at the center of the inner tube, the planar structure of the reinforcing tube is a hexagonal structure, and multiple reinforcing plates are fixedly connected to the corners of the reinforcing tube.

[0010] By adopting the above technical solution, the reinforced tube makes the racket face angle more stable and improves the accuracy of ball control.

[0011] Furthermore, the reinforcing plate and the reinforcing tube form a cavity, a first elastic ball is provided at the center of the reinforcing tube, and a second elastic ball is provided in the cavity.

[0012] By adopting the above technical solution, and by setting multiple cavities and filling them with a first elastic ball and a second elastic ball, vibration can be buffered when subjected to impact force, reducing the impact of high-frequency vibration on the wrist.

[0013] Furthermore, a reinforcing rod is fixedly connected to the top of the connector, and the top of the reinforcing rod is fixedly connected to the bottom of the ball frame.

[0014] By adopting the above technical solution, the overall rigidity of the shaft is further improved by the added reinforcing bar, making energy transfer more efficient, reducing fatigue wear after long-term use, and improving the durability of the racket.

[0015] Furthermore, a handle is fixedly connected to the bottom end of the middle tube, and a fixing groove is provided at the top end of the handle.

[0016] By adopting the above technical solution, a fixing groove is set between the shaft and the grip, which improves the overall rigidity of the shaft, optimizes the energy transfer path, reduces energy loss during impact, and increases the initial velocity of the ball.

[0017] In summary, this utility model has the following beneficial effects: Through its honeycomb structure design, the central tube forms multi-directional support during impact, improving torsional strength, effectively reducing torsional deformation at the moment of impact, making the racket face angle more stable, improving control accuracy, and reducing unforced errors. The honeycomb structure contains multiple cavities filled with first and second elastic balls, which buffer vibrations when subjected to impact, reducing the impact of high-frequency vibrations on the wrist. It also provides energy storage and release functions, accelerating deformation recovery and allowing the central tube to rebound to its initial state more quickly, improving the response speed of continuous shots. To meet the demands of high-speed offensive and defensive transitions, a fixing groove is installed between the shaft and the grip to improve the overall rigidity of the shaft, optimize the energy transfer path, reduce energy loss during impact, increase initial shot velocity, and enhance the durability of the shaft, reducing fatigue wear after prolonged use and extending the racket's lifespan. This invention, through multiple optimizations such as a honeycomb structure, shaft reinforcement, and elastic element cushioning, achieves higher torsional strength, faster rebound speed, and more stable shot control without increasing weight. Suitable for high-level competition and professional training, it provides badminton players with a superior user experience. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A badminton racket with a special shaft, such as Figures 1-4 As shown, the device includes a ball frame 1, with multiple sets of net cables 2 fixedly connected to the inner wall of the ball frame 1. Two sets of connecting rods 3 are fixedly connected to the bottom of the ball frame 1, and the two sets of connecting rods 3 are arc-shaped. Connecting parts 4 are fixedly connected to the bottom of the two sets of connecting rods 3, and a central tube 5 is fixedly connected to the bottom of the connecting parts 4. The central tube 5 has a hexagonal planar structure and a honeycomb structure 6 inside. Specifically, by adopting the honeycomb structure 6, which has multiple reinforcing tubes 601 and reinforcing plates 602 inside, multi-directional support is formed when under force, improving torsional strength, making the central tube 5 maintain a more stable shape under impact, reducing deformation, and improving ball control accuracy.

[0026] Please see Figure 2 and Figure 3 The honeycomb structure 6 includes a reinforcing tube 601, a reinforcing plate 602, a cavity 603, a first elastic ball 604, and a second elastic ball 605. The reinforcing tube 601 is located at the center inside the middle tube 5. The planar structure of the reinforcing tube 601 is a hexagonal structure. Multiple reinforcing plates 602 are fixedly connected to the corners of the reinforcing tube 601. The reinforcing plates 602 and the reinforcing tube 601 form a cavity 603. The first elastic ball 604 is provided at the center of the reinforcing tube 601, and the second elastic ball 605 is provided in the cavity 603.

[0027] Specifically, the honeycomb structure 6 has multiple cavities 603 inside, which can buffer part of the impact force and reduce the vibration amplitude during the ball hitting process. At the same time, the cavities 603 are filled with a first elastic ball 604 and a second elastic ball 605. These elastic elements can store part of the energy after being compressed and provide a reverse support force when the deformation is released, which accelerates the recovery speed of the middle tube 5, making it rebound to the initial state more quickly and improving the response speed during continuous ball hitting.

[0028] Please see Figure 1 and Figure 4 The top of the connector 4 is fixedly connected to the reinforcing rod 7, and the top of the reinforcing rod 7 is fixedly connected to the bottom of the frame 1. The bottom of the middle tube 5 is fixedly connected to the grip 9, and the top of the grip 9 is provided with a fixing groove 8. Specifically, the reinforcing rod 7 further improves the overall rigidity of the middle tube 5, making energy transfer more efficient, while reducing fatigue wear after long-term use and improving the durability of the racket.

[0029] The working principle of this utility model is as follows: When in use, at the moment of impact, the net string 2 transmits the impact force to the frame 1 and further to the tube 5. In this process, the traditional cylindrical tube is prone to torsional deformation, which leads to the deviation of the hitting angle. However, this device adopts a honeycomb structure 6, which has multiple reinforcing tubes 601 and reinforcing plates 602 inside. When subjected to force, it forms multi-directional support, improves torsional strength, and makes the tube 5 maintain a more stable shape under impact, reducing deformation and improving ball control accuracy.

[0030] To optimize the ball rebound performance, the honeycomb structure 6 has multiple cavities 603 inside, which can buffer part of the impact force and reduce the vibration amplitude during the ball hitting process. At the same time, the cavities 603 are filled with first elastic balls 604 and second elastic balls 605. These elastic elements can store part of the energy after being compressed and provide reverse support force when the deformation is released, which accelerates the recovery speed of the middle tube 5, making it rebound to the initial state more quickly and improving the response speed during continuous ball hitting.

[0031] The reinforcing bar 7 further improves the overall rigidity of the shaft 5, making energy transfer more efficient, while reducing fatigue wear after long-term use and improving the durability of the racket.

[0032] In summary, this utility model, through structural optimizations such as the honeycomb structure 6 design, the reinforcing tube 601 support, the cavity 603 buffer, and the elastic ball energy storage, enables the racket shaft to have stronger torsional resistance, faster rebound speed, and more stable hitting control, thereby improving the hitting feel and durability and meeting the design requirements of high-performance badminton rackets.
