TECHNICAL FIELD

[0002] Badminton is a sport with a long history, and early badminton rackets were mostly made of wood, which were heavy and less flexible. Modern rackets are mostly made of lightweight materials such as carbon fiber and titanium alloy, which reduce weight while increasing strength, making it easier for players to exert force and improve control. Badminton is usually made of goose or duck feathers, and the head is made of softwood to ensure flexibility.

[0003] Badminton requires high-quality equipment, and the flight path, stability, and feel of the badminton will directly affect the outcome of the game. The structure of traditional badminton is not durable, and the weight and structural design of the head cannot effectively resist air interference, resulting in unstable flight path and easy deviation from the trajectory during high-speed hitting. It cannot meet the needs of high-intensity training and competition. Therefore, we designed a durable badminton to solve the above problems. SUMMARY

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0025] EMBODIMENT

[0026] In this embodiment, with reference to Figures 1-4 A strong durable shuttlecock, comprising a shuttlecock body 1, the shuttlecock body 1 comprising a head part 2, a shock-absorbing spiral part 3 and a tail part 4.

[0027] Four inclined and twisted air guide holes 201 are formed on the head part 2, and the inclination angle of each air guide hole 201 is 10-15 degrees; wherein the air guide hole 201 is throughly arranged, and adjacent air guide holes 201 are arranged at an angle of 90 degrees.

[0028] In this embodiment, the air guide hole 201 is designed on the head part 2, which can draw lessons from the principle of gun barrel rifling to make the head part 2 spin in the air flow. The inclination angle of each air guide hole 201 is set to 10-15 degrees, which optimizes the air inflow angle and makes the air form a spiral flow in the hole, thereby giving the ball a spin effect. The spin can increase the stability of the flight direction on one hand, and resist the interference of external air flow on the other hand, which can reduce the probability of the ball head being deflected by the air flow.

[0029] More specifically, the air guide hole with an inclination angle of 10-15 degrees can effectively reduce air resistance and energy loss during the flight of the shuttlecock, and when the air flow passes through the air guide hole, its direction will be deflected. This inclined structure can help the air flow along the surface of the shuttlecock, making the flight trajectory of the shuttlecock more stable, thereby improving the flight distance and stability.

[0030] At the same time, the inclined and twisted air guide hole design can more efficiently guide the air flow over the surface of the shuttlecock, optimizing the aerodynamic performance. By reducing the friction between the shuttlecock and the air, the air resistance during flight is reduced, the flight speed of the shuttlecock can be improved, and the energy loss caused by air resistance is also reduced.

[0031] In this embodiment, one side of the shock-absorbing spiral part 3 is connected with the head part 2, and the other side of the shock-absorbing spiral part 3 is connected with the tail part 4. The cross section of the shock-absorbing spiral part 3 is a rectangular spiral elastic structure, which not only optimizes the elastic coefficient, but also effectively reduces the impact force when hitting the ball.

[0032] The spiral elastic structure has adjustable elasticity, which can provide different elasticity and hitting feeling according to user needs by changing the material and pitch of the spiral part, meeting different training and competition needs.

[0033] It should be noted that the flight stability of the shuttlecock is highly dependent on the position of its center of gravity. In the present embodiment, one side of the connection between the head portion 2 and the shock-absorbing spiral portion 3 is embedded with one of a metal sheet or plastic particles. The metal sheet is one or more of a copper sheet or an iron sheet, and the plastic particles are one or more of polyethylene or polypropylene.

[0034] Through the above, the head portion 2 adjusts the weight distribution by embedding high-density materials such as precisely designed small metal sheets or high-density plastic particles, so that the center of gravity is accurately positioned at the connection between the head portion and the shock-absorbing spiral portion 3. The center of gravity at this position can ensure that the shuttlecock is evenly stressed during flight, reducing deviation and maintaining a stable flight trajectory. In order to adapt to different hitting intensities and flight requirements, the mass and volume of the counterweight material can also be adjusted as needed.

[0035] In the present embodiment, the tail wing portion 4 includes a first support ring 401, a second support ring 402, and a wing assembly 403 composed of a plurality of inclined wings, which are installed equidistantly between the first support ring 401 and the second support ring 402. The diameter of the second support ring 402 is greater than that of the first support ring 401.

[0036] The design of the inclined wings can refer to the propeller structure of a submarine, which is composed of a plurality of inclined wings to further enhance the spinning ability of the shuttlecock and ensure the stability of the flight trajectory.

[0037] In the present embodiment, the tail wing portion 4 contains a plurality of inclined inclined wings arranged between the first support ring 401 and the second support ring 402. The main function of these inclined wings is to generate a rotational torque around the axis when air flows through, pushing the ball to spin. The inclination angle of the inclined wings is usually set to 45-70 degrees to ensure the best rotational torque generation. The relationship between the moment and the angle is given by the formula: M = L × F × sin(θ).

[0038] In the above, the spin can significantly improve the flight stability, reduce the deviation or stall of the shuttlecock caused by air disturbance, and ensure the stability and accuracy of the shuttlecock during flight. The increase in spin allows the shuttlecock to maintain a longer straight flight, reducing the change in trajectory. Especially when the shuttlecock is against the wind, the inclined wings can effectively improve the wind resistance, making the shuttlecock fly more stably and controllably, without falling or deviating prematurely due to air disturbance. This is particularly important for the control of the shuttlecock, especially in fast motion and high-intensity competition, where the stability of the flight trajectory determines the accuracy of the attack or defense.

[0039] More specifically, in the design, the material, thickness and surface roughness of the inclined wings can be fine-tuned to adapt to different flight speeds. The material of the inclined wings is usually a lightweight and durable polymer material, such as reinforced nylon or composite material, which can provide rotational force while reducing additional weight.

[0040] The diameter of the second support ring 402 is larger than that of the first support ring 401, so that there is a height difference in the tail wing part 4. The height difference wall structure of the tail wing part 4 forms an air flow difference between the high and low surfaces through air flow. The around-axis moment formed by the air flow difference further enhances the rotation effect of the shuttlecock, helping the ball maintain stability during flight. In the specific design, the size and inclination angle of the height difference can be adjusted according to the expected flight stability and resistance requirements. The wall surface inclination angle is usually controlled between 45-70 degrees. In addition, to reduce weight and increase rotational moment, micro-holes can be opened between the high and low walls to effectively guide the airflow and balance the rotational force.

[0041] In the above embodiment, the head part 2 of the shuttlecock 1 is responsible for gravity center control and initial spin generation. Through reasonable weight distribution and the design of the air guide hole 201, the head part 2 achieves stability enhancement during flight. The weight of the head part 2 is balanced by the lightweight design of the shock-absorbing spiral part 3, making the overall flight performance more consistent with the principles of aerodynamics.

[0042] The shock-absorbing spiral part 3 provides positive wind resistance and is responsible for speed reduction and flight trajectory control. The material of the shock-absorbing spiral part 3 is selected to be lightweight, and the positive wind resistance is adjusted by increasing the windward area. The overall structure of the shock-absorbing spiral part 3 allows the shuttlecock to quickly decelerate during flight, adapting to different competition requirements.

[0043] The inclined wings and walls of the tail wing part 4 generate around-axis moment under the action of airflow, ensuring the shuttlecock has the ability to spin. The material and inclination angle of the rotating components are precisely set through experiments to ensure the spin stability of the shuttlecock under different force strikes.

[0044] Each part is accurately matched and cooperates to ensure that the shuttlecock maintains optimal performance under different conditions.

[0045] Among them, when the ball is hit quickly, the weight of the head part 2 and the spin structure of the tail wing part 4 ensure the stability of the flight direction; the wind resistance adjustment of the rotating wind resistance wings and wall structure ensures that the ball still maintains rotational balance at high speed.

[0046] When flying at medium or low speed, the air guide hole 201 of the ball head 2 increases the spin, cooperates with the positive wind resistance of the shock absorbing spiral part 3, achieves the natural speed reduction effect, and the inclined wing design of the tail wing part 4 can adaptively adjust the rotation rate according to the airflow, and ensure smooth transition.

[0047] In the utility model, the air guide hole 201 of the ball head 2 and the inclined wing design of the tail wing part 4 can effectively reduce airflow interference, making the flight trajectory more stable; the spiral elastic structure of the shock absorbing spiral part 3 reduces the impact force when hitting the ball during use, improves the hitting feel, and reduces the wear of the racket and the shuttlecock; at the same time, by changing the spiral structure and material elasticity, personalized hitting experience can be provided according to the needs of athletes. The shuttlecock in the utility model is suitable for various sports scenes, and can provide excellent performance whether it is daily training or high-level competition.
