Description

Technical Field

[0001] This utility model relates to a sphere, and more particularly to a badminton shuttlecock, belonging to the technical field of badminton shuttlecocks. 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 badminton shuttlecock with a simple and reasonable structural design, light weight, high strength, good flexibility, low environmental pollution, and good composite fastness. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and provide a badminton shuttlecock with a simple and reasonable structural design, stable and reliable, light weight, high strength, good flexibility, low environmental pollution, and good composite fastness.

[0007] The technical solution adopted by this utility model to solve the above problems is: the badminton shuttlecock includes a head, a high-density coil and several sets of feather structures, characterized in that: several sets of feather structures are installed on the inner side of the head, each set of feather structures includes matching feather blades and feather shafts, the surface of each feather shaft is provided with feather blades, and the feather shafts are fixed to each other by multiple high-density coils.

[0008] Preferably, in the feather structure of this invention, the feather shaft is inserted into the ball head at an inclined angle, and the plane of insertion between the feather shaft and the ball head is between 0.1° and 3°.

[0009] Preferably, the feather piece of this invention adopts a multi-layer composite structure, which is a 2-4 layer composite structure; while reducing weight, it increases the strength of the feather piece.

[0010] Preferably, the present invention also includes multiple reinforcing ribs, and the multi-layer composite structure is provided with transverse, oblique or mesh reinforcing ribs, which cover the main body of the feather pieces.

[0011] Preferably, the side cross-section of the feather in this invention has a corrugated or serrated structure; this increases the bonding strength between the feather and the feather shaft, making it less likely to loosen.

[0012] Preferably, the feather piece of this invention is made of one of foamed cotton, sprayed fleece or meltblown fabric.

[0013] Preferably, the feather shaft of this invention is made of either carbon fiber or aramid fiber; carbon fiber is lightweight, has good resilience, and high strength, while aramid fiber is soft and has good toughness.

[0028] 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.

[0029] Example

[0030] See Figures 1 to 9 In this embodiment, the badminton shuttlecock includes a head 2, a high-density coil 3, and several sets of feather structures 1. Several sets of feather structures 1 are installed on the inner side of the head 2. Each set of feather structures 1 includes a feather blade 11 and a feather shaft 12. Each feather shaft 12 has a feather blade 11 on its surface. The feather shafts 12 are fixed to each other by multiple high-density coils 3. The feather blades 11 adopt a multi-layer combination structure.

[0031] In this embodiment, the feather structure 1 consists of 16 pieces (the number can be selected according to the actual situation). The feather pieces 11 are made of foamed cotton, sprayed down cloth or meltblown cloth, and have a multi-layer (2-4 layers) combination structure, which reduces weight while increasing the strength of the feather pieces.

[0032] Based on the principles of bionics, the structure mimics the support structure of natural feathers. The multi-layered composite structure is reinforced with horizontal, diagonal, or mesh-like ribs 111. The ribs 111 cover the main body of the feather 11 and can be designed to vary in thickness, with the part closer to the feather shaft 12 being slightly thicker.

[0033] In this embodiment, the traditional insertion of the feather shaft 12 and the shuttlecock head 2 is a flat insertion, which is perpendicular to the insertion plane of the shuttlecock head 2 and has an outward standard angle with the central axis of the shuttlecock head 2. This application allows the shuttlecock head 2 to be inserted at an inclined angle between 0.1° and 3°. This method makes it easier to set the center point of the shuttlecock's counterweight 10mm above the insertion plane of the feather shaft 12 and the shuttlecock head 2.

[0034] 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.

[0035] 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 113, increasing strength and resisting bending.

[0036] In this embodiment, the feather shaft 12 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.

[0037] In this embodiment, the feather shaft 12 is designed to be thicker and thinner from the head 2, so that the counterweight can be controlled within a controllable range in the later stage.

[0038] In this embodiment, the feather shaft 12 does not extend to the top of the feather blade 11, leaving about 3 mm of unsupported state, which can effectively prevent passive damage to the feather blade 11 when hit by the shuttlecock.

[0039] 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 1 and the feather shaft 12, making it less likely to come loose.

[0040] In this embodiment, the feather shaft 12 and the feather piece 11 are bonded together using adhesive, hot-melt bonding, or ultrasonic bonding.

[0041] In this embodiment, the ball head 2 is made of plastic, composite cork, or other materials.

[0042] The composite process of the badminton shuttlecock in this embodiment is as follows: (S1) The feather pieces 11 are composited using ultrasonic bonding, adhesive bonding, or hot-melt bonding; (S2) The feather shaft 12 is made into a sheet or needle shape, coated with paint, and made with a thickness S of 0.6 mm, a chamfer R of 0.25 mm, and a width B of 2.3 mm. The depth H of the part inserted into the shuttlecock head 2 is about 10 mm, and the part of the feather shaft 12 inside the shuttlecock head 2 is thicker; (S3) The feather shaft 12 is inserted into the shuttlecock head 2 at an inclined angle, and the feather pieces 11 overlap each other, with an overlap range of 1-3 mm; (S4) Each feather shaft 12 is connected by a wire to form a high-density coil 3, and there are two or more high-density coils 3; (S5) Waterproof adhesive is applied to the feather shaft 12, the high-density coil 3, and the insertion point of the shuttlecock head 2.

[0043] This embodiment features innovative badminton shuttlecock and its composite process, and can be applied independently to badminton products.

[0044] Based on the above description, those skilled in the art are already able to implement it.

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.
