[0020] As Figures 1 to 5As shown, the artificial badminton includes a ball head 1, a feather bone 2 and a feather leaf 3 and a fixed binding rope 4, each feather bone and a piece of feather leaf constitute a group of feather pieces, the feather bone and the feather leaf are fixed by UV glue, the UV glue has the advantages of no obvious glue mark and high bonding strength, the artificial badminton is surrounded by fifteen or sixteen groups of feather pieces on the ball head, preferably fifteen groups of feather pieces, and most of the badminton using real hair at present is sixteen feather pieces, since the badminton of the utility model leaves a gap between the feather pieces to realize the control of air overflow and constitute the air directional effect, realize the stability of the flight trajectory of the badminton, the real feather in the prior art has V-shaped gaps between the hair, the V-shaped gaps constitute the air overflow channel, and the surface of the feather leaf of the utility model is smooth, therefore, the gap between the adjacent feather leaves is set, and the air overflow channel can be constituted, the fixed binding rope is fixed on the feather bone of the feather piece, and the artificial badminton is provided with a gap of 0.5mm-2mm between the adjacent feather leaves, preferably 0.7-1mm. The ball head is the wooden ball head in the prior art, which will not be described in detail here, the feather piece is circularly inserted at the bottom of the ball head and is fixed and positioned by using the fixed binding rope, and other accessories on the ball head, such as the curing glue and the polyurethane skin, are all in the prior art. And the gap between the outer edges of the feather leaves of the adjacent feather pieces is 0.5-2mm, preferably 1mm, the maximum width of the feather leaf is 13mm±0.2mm, and the end gradually decreases, the length of the feather leaf is 40mm±4mm, and the length of the feather bone is 75±3mm. When sixteen groups of leaves are used, the width of the feather leaf needs to be smaller.

[0021] The feather leaf 3 is made of high polymer foaming material, the feather leaf is closed-pore sheet material, and the thickness of the feather leaf is 0.4-1.0mm. The high polymer foaming material includes polyurethane foaming material, polypropylene foaming material, nylon foaming material, polystyrene foaming material and the like.

[0022] The feather bone 2 is made of carbon fiber material or glass fiber material as a base material and is wrapped with polyethylene material on the outer layer, the cross-sectional shape of the feather bone is rectangular or circular or oval, when the feather bone is a straight rod, the cross-sectional area of the feather bone is 0.6mm 2 -0.8mm 2 , preferably 0.7mm 2 . The rectangular material can be obtained by directly cutting the fiber material, and has the advantage of fast processing speed. The liquid polyethylene will penetrate during the wrapping process, so that the fiber material obtains fixation and strength.

[0023] The hair leaf 3 contains reinforcing fibers 31, the length of the reinforcing fibers is 1-3mm, the reinforcing fibers are carbon fibers, the reinforcing fibers 31 are mixed into the material in disorder and foamed together. As an improved embodiment, the reinforcing fibers can also be other reinforcing type fibers, including organic fibers and inorganic fibers, the organic fibers include: synthetic fibers such as aramid fiber, oxford fiber, polyester fiber, nylon fiber, vinylon fiber, polypropylene fiber, polyimide fiber, etc.; natural fibers such as cotton fiber, sisal, paper, etc.; inorganic fibers include: glass fiber, carbon fiber, boron fiber, whisker, asbestos fiber and metal fiber, etc.

[0024] The hair leaf 3 is formed by laminating two layers of high polymer foaming materials with different densities, preferably, one layer is 0.07g±0.01 / cm3, and the other layer is 0.03g±0.01 / cm3. Preferably, as another embodiment, the thickness of the two layers of high polymer foaming materials can be different.

[0025] The density of the high polymer foaming material of the hair leaf 3 is 0.07g±0.01 / cm3 and / or 0.03g±0.01 / cm3.

[0026] The hair bone is a long strip-shaped cone with a large head and a small head, wherein the thickness of the large head end is 1mm±0.3mm, the width is 1.5mm±0.3mm, the thickness of the small head end is 0.3mm±0.2mm, the width is 0.5mm±0.2mm, the length of the hair bone 2 is 70-75mm, and the large head of the hair bone is connected to the ball head; the hair leaf is connected to one end of the hair bone by UV glue, and the shape of the hair leaf is a long water drop shape with a pointed or round head and gradually decreasing width. The head of the hair leaf is semicircular, and the tail gradually decreases in width. Through three-point bending test and four-point bending test, when the thickness of the hair leaf is 0.4-0.6mm, the maximum load is measured to be 20-50N, and the deflection is 1-3mm. The hair bone is made of polyethylene + reinforcing fibers, which can obtain higher bending resistance. Through three-point bending test and four-point bending test, the maximum load is measured to be 50-100N, and the deflection is 5-10mm.

[0027] The hair bone and the hair leaf are bonded by a UV glue layer (not shown in the figure), as an alternative, other glues or materials that can achieve bonding can be used. The hair leaf is uniformly provided with a plurality of through holes of 0.3-0.4mm. Local small through holes can reduce the weight of the hair leaf, thereby reducing the total weight of the shuttlecock.

[0028] The hair bone is clamped between two layers of high polymer foaming materials with different densities. As another embodiment, the hair bone can be connected to the outside of the two layers of high polymer foaming materials.

[0029] In a common embodiment, the two sides of the leaf blade are symmetrical in size and have the same shape.

[0030] like Figure 4 As shown, the shape of the feather blades is asymmetrical, meaning that the area on one side of the blade at the feather attachment point is larger than the other. This asymmetrical structure results in different wind resistance on both sides of the blade. When the feather blades are arranged in an orderly ring, they generate a rotational shear force on the shuttlecock, causing it to spin and improving stability. Multiple through-holes of 1.0–4.0 mm are evenly distributed on both sides of the feather blades. Drilling these holes reduces the weight of the blades to some extent and allows for auxiliary stabilization by adjusting the direction of airflow. Improving airflow stabilizes the shuttlecock's flight trajectory. The spacing between the through-holes is 2–5 mm. Preferably, there are 2–5 holes per side, with 3 being more preferred.

[0031] The head of the feather blade is shaped like a pointed corner with a rounded edge. The pointed head can cut the airflow to a certain extent, thereby enhancing the stability of the shuttlecock's flight trajectory.

[0032] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
