Description

Technical Field

[0001] This utility model relates to the field of badminton technology, specifically to a synthetic plastic badminton shuttlecock. Background Technology

[0002] Due to the unstable supply and inconsistent quality of natural feathers, and the high cost and complex processing of feathers, synthetic shuttlecocks are a more economical and durable choice for everyday recreation or training.

[0003] Existing artificial shuttlecocks have a certain gap in flight stability compared to natural shuttlecocks because the deformation recovery speed of the feather vanes is not as fast as that of natural feathers. Utility Model Content

[0004] To address the aforementioned shortcomings, the technical problem to be solved by this invention is to provide an artificial plastic badminton shuttlecock that overcomes the gap in flight stability between existing technologies and natural badminton shuttlecocks.

[0005] Therefore, this application provides an artificial plastic badminton shuttlecock, including a shuttlecock head and a feather assembly. The feather assembly consists of multiple feather units evenly distributed circumferentially and connected end to end on the sides. Each feather unit includes a feather shaft and feathers fixed to the upper part of the feather shaft. The sides of two adjacent feathers are connected. The lower end of the feather shaft is inserted and fixed to the shuttlecock head. At least one annular kinetic energy collection ring is provided around the outer side of each feather shaft. The kinetic energy collection ring is located between the feathers and the shuttlecock head, and its shape is an open umbrella-like surface with the concave surface facing the shuttlecock head.

[0006] Based on the above technical solutions, when the badminton shuttlecock is in flight, the umbrella-shaped kinetic energy harvesting ring can generate a rotational torque due to the impact of airflow, which pushes the shuttlecock to rotate faster around its axis, improving its ability to resist external interference and making its flight trajectory more stable.

[0007] In the above technical solution, preferably, the lower part of each of the hair rods is fixed by at least one annular coil.

[0008] In the above technical solution, preferably, each feather shaft is provided with a power feather piece, which is sheet-shaped, extends toward the center of the feather assembly, and is inclined relative to the line connecting the center of the feather shaft and the center of the feather assembly.

[0009] In the above technical solution, preferably, the power bristles are disposed on the inner or outer surface of the bristle rod.

[0010] In the above technical solution, preferably, the power hair piece is rectangular and its long side is attached to the hair rod; or, the power hair piece is triangular, with its pointed end facing the ball head and its long side attached to the hair rod.

[0011] In the above technical solution, preferably, the hair bar is columnar, and the cross-sectional area gradually increases from the top of the hair piece to the ball head.

[0012] In the above technical solution, preferably, the cross-section of the kinetic energy harvesting coil is triangular.

[0013] In the above technical solution, preferably, at least one of the concave and convex surfaces of the kinetic energy harvesting ring is an arc surface.

[0014] In the above technical solution, preferably, the kinetic energy harvesting coil and the coil are integrally formed.

[0015] In the above technical solution, preferably, the feather assembly is integrally injection molded.

[0016] As can be seen from the above technical solution, the artificial plastic badminton shuttlecock provided by this utility model solves the problem of poor flight stability in existing technologies. Compared with existing technologies, this utility model has the following beneficial effects:

[0017] At least one annular kinetic energy harvesting ring is provided around the outer side of each shuttlecock shaft. The kinetic energy harvesting ring is shaped like an open umbrella, with the concave surface facing the shuttlecock head. When the shuttlecock is in flight, air impacts the umbrella-shaped kinetic energy harvesting ring from all directions, generating an asymmetrical pressure distribution on the concave surface of the umbrella, forming a rotational torque, which in turn propels the shuttlecock to rotate faster around its axis. This makes it more resistant to external interference (such as crosswinds and hitting deviations) and makes its flight trajectory more stable. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] To provide a clearer explanation and description of the technical solution and implementation method of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.

[0037] It should be noted that the directional terms such as "inner" and "outer", "front" and "back" and "left" and "right" in this article are based on the product's usage status. Obviously, the use of these directional terms does not limit the scope of protection of this solution.

[0038] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a synthetic plastic badminton shuttlecock, including a shuttlecock head 100 and a feather assembly 200.

[0039] The ball head 100 can be made of natural cork, composite cork, or foam plastic (foamed nylon or PU material).

[0040] The feather assembly 200 is composed of multiple feather units 210 that are evenly distributed along the circumference and connected end to end on the sides. Each feather unit 210 includes a feather shaft 211 and feathers 212 fixed to the upper part of the feather shaft 211. The sides of two adjacent feathers 212 are connected, and the lower end of the feather shaft 211 is inserted and fixed to the ball head 100.

[0041] The lower part of each feather shaft 211 is fixed by at least one annular coil 220. The coil 220 maintains the shape and position of each feather shaft 211, enhancing the stability of the feather assembly 200 and extending its service life. In this embodiment, the cross-section of the coil 220 is a regular square prism. Obviously, it can also be circular or elliptical, and this application is not limited to that.

[0042] At least one annular kinetic energy collection ring 230 is provided around the outer side of each hair bar 211. The kinetic energy collection ring 230 is shaped like an open umbrella, with its concave surface facing the ball head 100. The kinetic energy collection ring 230 is located between the hair bar 212 and the ball head 100, and multiple kinetic energy collection rings 230 are arranged at intervals.

[0043] Based on the design of the kinetic energy harvesting coil, this utility model has the following two typical implementation methods.

[0044] Example 1.

[0045] like Figure 4 , Figure 5 , Figure 6 As shown, the kinetic energy harvesting coil 230 and the coil 220 are integrally formed into a single structure.

[0046] Example 2.

[0047] like Figure 7 , Figure 8 , Figure 9 As shown, the kinetic energy harvesting ring 230 is arranged around the outer side of the hair rod 211.

[0048] In this application, the cross-section of the kinetic energy harvesting coil 230 is triangular. Obviously, at least one of the concave and convex surfaces of the kinetic energy harvesting coil 230 can also be designed as an arc surface.

[0049] In this application, at least one kinetic energy harvesting ring 230 is added to the middle of the shaft 211. Through a triple mechanism of aerodynamic torque amplification, gyro stabilization, and damping correction, the spin speed and flight stability of the badminton shuttlecock are improved.

[0050] First, the umbrella-shaped kinetic energy harvesting ring 230 generates a rotational torque due to the impact of airflow. As the shuttlecock flies, air impacts the umbrella-shaped kinetic energy harvesting ring from all directions. Due to the tilted or curved design of the umbrella surface, the airflow creates an asymmetrical pressure distribution on the concave surface, generating a rotational torque (similar to the principle of windmill blades), thus propelling the shuttlecock to accelerate its rotation around its axis. According to the law of conservation of angular momentum, the increased spin speed of the shuttlecock enhances its resistance to external disturbances (such as crosswinds and hitting deviations), resulting in a more stable flight trajectory.

[0051] Secondly, the kinetic energy harvesting coil converts linear kinetic energy into rotational kinetic energy. The kinetic energy of a traditional badminton shuttlecock mainly comes from the linear impact force when the shuttlecock is hit, while the umbrella-shaped structure can convert some of the axial flight kinetic energy into rotational kinetic energy through air resistance, thereby increasing the spin speed.

[0052] In addition, the umbrella-shaped structure guides airflow and reduces turbulence. Traditional badminton shuttlecocks, with their feathers, can generate turbulent drag due to uneven distribution during high-speed rotation. The symmetrical design of the umbrella-shaped ring regulates airflow and reduces rotational energy loss. The umbrella-shaped ring also increases the shuttlecock's lateral air resistance during flight. When the shuttlecock yaws due to external forces (such as hitting deviation), the umbrella surface generates a counter-torque through asymmetrical drag, quickly correcting its flight attitude.

[0053] In summary, this application's solution increases the badminton shuttlecock's spin speed through a kinetic energy harvesting coil, enhances its anti-interference capabilities by utilizing the gyroscope's stability principle, and results in a straighter flight trajectory. Furthermore, kinetic energy recovery extends the spin duration, leading to smoother deceleration and more precise landing.

[0054] To further improve the spin speed and stability of the badminton shuttlecock, such as... Figure 4 , Figure 9 As shown, the present application also provides a power feather plate 240 on the inner side of each feather shaft 211. The power feather plate 240 is sheet-shaped and extends towards the center of the feather assembly 200, and is inclined relative to the line connecting the center of the feather shaft 211 and the center of the feather assembly 200. That is, the plane X1 where the power feather plate 240 is located forms an angle O with the plane X2 where the line connecting the center of the feather shaft 211 and the center of the ball head 100 is located.

[0055] The power feather 240, in conjunction with the kinetic energy harvesting ring 230, can further enhance the spin speed and stability of the shuttlecock. Specifically, during the shuttlecock's flight, air impacts the concave surface of the kinetic energy harvesting ring 230 and is guided into the feather assembly 200 through the gap between the feather shafts 211. During this process, the air flows along the inclined surface of the power feather 240, thereby generating a rotational driving force, enhancing the shuttlecock's spin, and thus improving its flight stability.

[0056] In the above embodiments, the power hair clip 240 is disposed on the inner side of the hair rod 211, or it can be designed to be disposed on the outer side of the hair rod 211.

[0057] The shape of the power strip 240 can be designed as a rectangle, trapezoid, or arc.

[0058] like Figure 2 , Figure 11 As shown, the power feather 240 is rectangular in shape, with its long side fitting against the feather shaft 211 and positioned inside the feather assembly 200.

[0059] like Figure 10 , Figure 12 As shown, the power feather 240 is triangular in shape, with the tip pointing towards the ball head, and the long side is attached to the feather shaft 211 and disposed inside the feather assembly 200.

[0060] Please see again Figure 2 , Figure 3 In this application, the shaft 211 is prismatic, with the cross-sectional area gradually increasing from the tip of the feather 212 to the head 100. This design effectively controls the weight of the shaft, enhances its overall strength, and effectively withstands instantaneous stress during impact, thereby improving the shuttlecock's durability and extending its lifespan.

[0061] In this embodiment, the cross-section of the hair rod 211 is a regular square prism.

[0062] The proposed solution involves integral injection molding of the feather assembly 200, resulting in high production efficiency and good product consistency.

[0063] Based on the above description of specific embodiments, the artificial plastic badminton shuttlecock provided by this utility model has the following advantages compared with the prior art:

[0064] First, each feather shaft below the feather has at least one annular kinetic energy harvesting ring on its outer side. The kinetic energy harvesting ring is shaped like an open umbrella with its concave surface facing the head of the shuttlecock. It can improve the spin speed and flight stability of the shuttlecock through a triple mechanism of aerodynamic torque amplification, gyro stabilization, and damping correction.

[0065] Secondly, each feather shaft has a power feather plate on its inner side. This power feather plate, in conjunction with the energy harvesting ring, further increases the shuttlecock's spin speed and stability.

[0066] Finally, it should be noted that the terms "comprising," "including," or any other variations thereof as used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising a…" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
