Abstract
Description
Technical Field
[0001] This utility model relates to a badminton shuttlecock, and more particularly to a feather structure for use in a badminton shuttlecock, which belongs to the field of badminton technology. Background Technology
[0002] Traditional badminton shuttlecocks are composed of a head and a body. The body is made by cutting, shaping, gluing, and inserting duck or goose feathers, followed by stringing and gluing.
[0003] With social development and the advancement of industrial automation, natural duck or goose feathers have several insurmountable drawbacks: 1) Collection is difficult and resources are limited, with feather pieces only available from some farms and slaughterhouses; 2) Feather pieces contain hair follicles and cortical organic matter, requiring disinfection to prevent infection; 3) They cannot be stored for too long, as they are prone to mold and deformation; 4) Naturally collected feather pieces vary greatly in weight and quality, requiring sorting, which is time-consuming and labor-intensive; 5) Due to individual differences, each feather piece or sphere cannot be mechanically processed, and final product testing cannot be replaced by machinery; 6) Environmental waste, as the disposal of scraps and adhesives requires environmental compensation; 7) Due to the inability to standardize production and the large errors in manual testing, the finished product qualification rate is low; 8) All manufacturers require a large amount of labor and experienced employees, resulting in extremely high costs.
[0004] Artificial shuttlecocks are a developing trend, as they can replace existing natural feathers, making automated mechanical operation a reality. They are increasingly valued by manufacturers and used by sports participants, with some brands already launching several models. However, drawbacks still exist: 1) Feathers are easily broken; 2) The shuttlecock's direction is obstructed when hit by gravity; 3) Feathers are easily deformed and cracked; 4) The center of gravity is prone to deviation, resulting in unstable flight; 5) Excessive glue usage makes weight control difficult; 6) Poor user experience.
[0005] Therefore, it is particularly necessary to provide a feather structure that is simple and reasonable in design, lightweight, high in strength, flexible, environmentally friendly, and has good composite strength. Utility Model Content
[0006] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and provide a feather structure for badminton shuttlecocks that is simple and reasonable in design, stable and reliable, lightweight, high in strength, flexible, environmentally friendly, and has good composite strength.
[0007] The technical solution adopted by this utility model to solve the above problems is: a feather structure for badminton shuttlecock, including feathers, wherein the feathers adopt a multi-layer composite structure, characterized in that: it also includes reinforcing ribs, porous structures and M-shaped structures, and transverse, oblique or mesh reinforcing ribs are provided between the multi-layer composite structures, the reinforcing ribs covering the main body of the feathers; each individual feather has a porous structure on one side, and the feather is an M-shaped structure forming an angle of 0.1-3°.
[0008] Preferably, the feather pieces in this invention are arranged in a staggered stacking configuration to increase strength and resist bending.
[0009] Preferably, the reinforcing ribs of this invention are of varying thicknesses, with the thicker ribs closer to the feather shaft.
[0010] Preferably, the feathers described in this invention adopt a 2-4 layer combination structure.
[0011] Preferably, the porous structure of this invention consists of multiple crescent-shaped holes; wind resistance is controllable, increasing the lifespan of the feathers.
[0012] Preferably, the feather piece of this invention is made of one of foamed cotton, sprayed fleece or meltblown fabric.
[0013] Compared with the prior art, this utility model has the following advantages and effects: (1) The overall structure design is simple and reasonable, stable and reliable. The feather pieces are made of foamed cotton, sprayed fleece or meltblown cloth, and multi-layer combination, which reduces the weight and increases the strength of the feather pieces. A porous structure is designed on one side of each individual feather piece. The porous structure is a multi-crescent-shaped hole, which controls the wind resistance and increases the life of the feather pieces. (2) The feather pieces are set with an M-shaped structure, forming an angle of 0.1-3°. The middle is thick and heavy, and the two sides are light. It has good flexibility and high strength, and is suitable for feather pieces to be stacked at a standard angle. The continuous M-shaped structure increases the strength and resists bending. (3) The composite process of the feather pieces uses ultrasonic composite process to replace the existing glue composite process. The composite strength is good, the weight is light, the manual labor is less, and the environmental pollution is less. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0022] Example
[0023] See Figures 1 to 6 In this embodiment, the feather structure in the badminton shuttlecock includes feathers 11, reinforcing ribs 111, a porous structure, and an M-shaped structure. The feathers 11 adopt a multi-layer composite structure, with transverse, oblique, or mesh-like reinforcing ribs 111 arranged between the multi-layer composite structures. The reinforcing ribs 111 cover the main body of the feathers 11. Each individual feather 11 has a porous structure on one side. The feathers 11 have an M-shaped structure, forming an angle of 0.1-3°.
[0024] In this embodiment, the feather piece 11 is made of foamed cotton, sprayed down cloth or meltblown cloth, with a multi-layer (2-4 layers) combination structure, which reduces weight while increasing the strength of the feather piece.
[0025] Based on the principles of bionics, mimicking the support structure of natural feathers, the multi-layered composite structure is provided with horizontal, diagonal, or mesh-like reinforcing ribs 111. The reinforcing ribs 111 cover the main body of the feather 11 and can be designed to be of varying thickness, with the part closer to the feather shaft being slightly thicker.
[0026] Based on aerodynamic principles, a porous structure 112 is designed on one side of each individual feather 11. This porous structure consists of multiple crescent-shaped holes, which are used for the rotation and airflow exchange during the flight of the badminton shuttlecock, thereby reducing weight and making the flight more stable. The multiple crescent-shaped holes allow for controllable wind resistance and increase the lifespan of the feathers.
[0027] In this embodiment, the structure of the feather piece 11, viewed from a tangential section, can be a slightly M-shaped structure 113, forming an angle of 0.1-3°. It is thick and heavy in the middle and light on both sides, with good flexibility and high strength, and is suitable for the staggered stacking of feather pieces 11 at a standard angle. Viewed from an oblique section, it can be a continuous M-shaped structure, increasing strength and resisting bending.
[0028] Each feather structure includes a feather blade 11 and a feather shaft. Each feather shaft has a feather blade 11 on its surface, and the feather shafts are fixed together by multiple high-density coils.
[0029] In this embodiment, the feather shaft is made of carbon fiber, which has the advantages of being lightweight, having good resilience, and high strength; or it can be made of aramid fiber, which has the advantages of being soft and having good toughness.
[0030] In this embodiment, the feather shaft is designed to taper from the tip of the shuttlecock, so that the counterweight can be controlled within a manageable range in the later stages.
[0031] In this embodiment, the feather shaft does not extend to the tip of the feather blade, leaving about 3 mm of unsupported state, which can effectively prevent passive damage to the feather blade 11 when hit by the shuttlecock.
[0032] In this embodiment, the side section of the feather piece 11 is provided with a corrugated or serrated structure 114; this increases the bonding strength between the feather piece and the feather shaft, making it less likely to loosen.
[0033] Based on the above description, those skilled in the art are already able to implement it.
[0034] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their parts and components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in these claims, all of which should fall within the protection scope of this utility model.
