Description

Technical Field

[0001] This utility model relates to the field of sports equipment manufacturing technology, and in particular to a guide pattern for a badminton shuttlecock head. Background Technology

[0002] Badminton is an indoor sport played over a net, using long-handled net rackets to hit a small ball made of feathers and cork. Matches are played on a rectangular court separated by a net. Players use various serves, shots, and movements to hit the shuttlecock back and forth across the net, aiming to prevent it from landing within their own penalty area or to force an opponent to make a mistake. As a globally popular sport, the flight stability of the shuttlecock directly affects the fairness of the game and the performance of the players. Traditional badminton shuttlecock heads often feature smooth surfaces or simple circular groove designs, lacking refined aerodynamic optimization.

[0003] The existing badminton shuttlecocks have unstable rotation speeds during flight, which makes them susceptible to lateral airflow interference and vibration at high speeds. This can lead to severe shaking, making it difficult for athletes to accurately judge the direction and landing point of the shuttlecock, thus failing to meet the standards for competition shuttlecocks set by the Badminton World Federation. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide a guide pattern for the head of a badminton shuttlecock.

[0005] The technical solution of this utility model is as follows: a guide pattern for a badminton shuttlecock head, comprising a hemispherical rigid plastic structure shuttlecock head base and a guide pattern body disposed on the surface of the shuttlecock head base. A plurality of feathers are fixedly connected to the bottom of the shuttlecock head base, and the plurality of feathers are arranged at equal intervals. The guide pattern body includes 8-12 inclined grooves, and the grooves are distributed at equal intervals along the generatrix direction of the shuttlecock head base.

[0006] By adopting the above technical solution and setting the airflow pattern, a stable turbulence can be formed on the surface of the shuttlecock head base to reduce the generation of air vortices, thereby reducing the speed fluctuation of the shuttlecock and ensuring that it always maintains a head-forward posture during flight.

[0007] In a preferred embodiment, each of the grooves has a depth of 0.5-1.5 mm and a width of 1.5-2 mm.

[0008] By adopting the above technical solution, the trench size can be determined according to the actual situation.

[0009] In a preferred embodiment, the spacing between adjacent grooves is 3-5 mm, and the length of the groove covers more than 70% of the surface area of ​​the ball head substrate.

[0010] By adopting the above technical solution, the airflow can be guided to pass quickly through the surface of the ball head substrate, avoiding the formation of a high-pressure zone in the local area of ​​the ball head substrate.

[0011] In a preferred embodiment, the top of the trench is provided with an arc-shaped protrusion structure.

[0012] By adopting the above technical solution, the impact force of airflow can be effectively dispersed.

[0013] In a preferred embodiment, two retaining rings are used to securely connect the plurality of feather pieces.

[0014] By adopting the above technical solution and setting the fixing ring, the overall structural stability of the badminton shuttlecock can be optimized.

[0015] In a preferred embodiment, the retaining ring is made of polycarbonate.

[0016] By adopting the above technical solution, the connection strength between the shuttlecock base and the feathers is enhanced.

[0017] In a preferred embodiment, the axis of each groove forms an angle of 15°-25° with the feather mounting direction.

[0018] By adopting the above technical solution, the force distribution is more uniform.

[0019] In a preferred embodiment, the trench has a U-shaped cross-section.

[0020] By adopting the above technical solution and through the reasonable design of the air guide pattern, the force distribution of the ball head base is more uniform when it frequently impacts the racket.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when the badminton shuttlecock is flying at high speed in the air, these wind-guiding patterns can make the airflow form a stable turbulence on the surface of the shuttlecock head, thereby reducing the generation of air vortices, thus reducing the rotational speed fluctuation of the badminton shuttlecock, ensuring that it always maintains a head-forward posture during flight, greatly reducing the deviation of the flight trajectory caused by unstable rotational speed, making the flight of the badminton shuttlecock more stable and controllable, so as to meet the stringent standards of the International Badminton Federation for the flight stability of the shuttlecock used in competitions.

[0022] 2. In this utility model, the hemispherical rigid plastic structure of the shuttlecock base itself has strong impact resistance. Combined with the fixing ring made of polycarbonate material to reinforce the feathers, it not only enhances the connection strength between the shuttlecock base and the feathers, but also effectively reduces the shaking and wear of the feathers during the hitting process.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] Reference Figure 1-4 A guide pattern for a badminton shuttlecock head includes a hemispherical rigid plastic structure shuttlecock head base 1 and a guide pattern body 2 disposed on the surface of the shuttlecock head base 1. Multiple feathers 5 are fixedly connected to the bottom of the shuttlecock head base 1 and are arranged at equal intervals. The guide pattern body 2 includes 8-12 inclined grooves, which are distributed at equal intervals along the generatrix of the shuttlecock head base 1. When the badminton shuttlecock is flying at high speed in the air, these guide pattern bodies 2 can make the airflow form a stable turbulence on the surface of the shuttlecock head base 1 to reduce the generation of air vortices, thereby reducing the rotational speed fluctuation of the badminton shuttlecock and ensuring that it always maintains a head-forward posture during flight. This greatly reduces the deviation of the flight trajectory caused by unstable rotational speed, making the flight of the badminton shuttlecock more stable and controllable, so as to meet the stringent standards of the Badminton World Federation for the flight stability of the shuttlecock used in competitions.

[0027] Specifically, each groove is 0.5-1.2mm deep and 1.5-2mm wide, with a spacing of 3-5mm between adjacent grooves. The groove length covers more than 70% of the surface area of ​​the shuttlecock base 1. The top of the groove is provided with an arc-shaped protrusion structure 3. In crosswind conditions, the arc-shaped protrusion structure 3 can effectively disperse the impact force of the airflow, while the large-area air-guiding pattern body 2 can guide the airflow to pass quickly through the surface of the shuttlecock base 1, avoiding the formation of a high-pressure zone in the local area of ​​the shuttlecock base 1, thereby significantly reducing the shaking amplitude of the badminton shuttlecock.

[0028] Specifically, two fixing rings 4 are fixedly connected between multiple feather pieces 5. The setting of fixing rings 4 can optimize the overall structural stability of the badminton shuttlecock, ensuring that the feather pieces 5 are not easy to loosen or fall off during high-speed flight and violent hitting. The fixing rings 4 are made of polycarbonate material. The hemispherical hard plastic structure of the shuttlecock head base 1 itself has strong impact resistance. With the fixing rings 4 made of polycarbonate material to reinforce the feather pieces 5, it not only enhances the connection strength between the shuttlecock head base 1 and the feather pieces 5, but also effectively reduces the shaking and wear of the feather pieces 5 during hitting. The axis of each groove is at an angle of 15°-25° with the installation direction of the feather pieces 5. The cross-section of the groove is U-shaped. The reasonable design of the air guide pattern body 2 makes the force distribution of the shuttlecock head base 1 more uniform when it frequently hits the racket, further extending the service life of the shuttlecock head base 1.

[0029] Working principle: When the shuttlecock is flying at high speed in the air, these wind-guiding pattern main bodies 2 can make the airflow form a stable turbulence on the surface of the shuttlecock head base 1 to reduce the generation of air vortices, thereby reducing the speed fluctuation of the shuttlecock and ensuring that it always maintains a head-forward posture during flight. In crosswind environment, the arc-shaped protruding structure 3 can effectively disperse the impact force of the airflow, while the large area of ​​the wind-guiding pattern main bodies 2 can guide the airflow to pass quickly through the surface of the shuttlecock head base 1, avoiding the formation of high pressure areas in the local area of ​​the shuttlecock head base 1, thereby significantly reducing the shaking amplitude of the shuttlecock. In addition, the hemispherical hard plastic structure of the shuttlecock head base 1 itself has strong impact resistance. Combined with the fixing ring 4 made of polycarbonate material to reinforce the feathers 5, it not only enhances the connection strength between the shuttlecock head base 1 and the feathers 5, but also effectively reduces the shaking and wear of the feathers 5 during the hit.
