[0030] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] like Figures 1 to 5 As shown, in a preferred first embodiment of the present invention, the artificial badminton shuttlecock 1 includes a head 11, a plurality of feathers 12, and connecting lines 13. Each feather 12 includes a shaft 121 and feathers 122. One end of the shaft 121 of each feather 12 is inserted into the head 11 and is spaced apart around the circumference of the head 11. The feathers 122 are located at the other end of the shaft 121. Connecting lines 13 connect the shafts 121 of each feather 12. The number of feathers 12 can be 12 or 15, and the specific number is not limited. It can be determined according to the size, shape, and weight distribution of the feathers 122, as long as they are distributed along the head 11 to form the shape of a regular badminton shuttlecock 1.

[0032] Combination Figures 2 to 5 As shown, the feather 122 is connected to one end of the shuttlecock 121. Preferably, the feather 122 has a plurality of through holes A distributed on it. The number of through holes A is not limited. Depending on the weight distribution requirements, the through holes A can be positioned near the ball head 11, away from the ball head 11, or distributed in multiple positions on the feather 122. The size of the through holes A at each position can be the same or different. Based on the arrangement of the through holes A, the weight gradient of the feather 122 can be distributed as needed, improving the stability of the movement. The distribution of the holes directly affects the feel of the net shot and the touch of the shot.

[0033] The through hole A can be one or more of the following shapes: circular, elliptical, polygonal, or irregular. The size of the hole can be in the range of 0.5-3mm. It can serve both to distribute weight and for aesthetic decoration, meeting the needs of different users. Preferably, the through holes A on each piece 122 are symmetrically arranged relative to their respective bob 121, which can ensure weight symmetry and make the wind resistance more uniform during movement.

[0034] In some embodiments, the feather 122 includes a first layer 1221 and a second layer 1222 stacked and fixed together. The first layer 1221 and the second layer 1222 are made of different materials. The first layer 1221 is a high-density plastic material, while the second layer 1222 is a low-density, soft, compressible material. The density of the first layer 1221 is greater than that of the second layer 1222. The second layer 1222 can reduce the overall weight of the shuttlecock 1. The plastic first layer 1221 can enhance the strength and abrasion resistance of the feather 122. During the hitting of the shuttlecock and during collisions with other objects, the internal second layer 1222 will not be damaged, thus extending the lifespan of the feather 122 and the shuttlecock 1.

[0035] The first layer 1221 is made of TPU or silicone material, which can be die-cut from sheet material or formed by injection molding. The second layer 1222 is made of foam material or nylon mesh, which can be die-cut from foamed sheet material or nylon mesh sheet, or formed by foaming foam material.

[0036] The outer surface of the first layer 1221 has a texture. The texture can be a pit formed on the surface or a bumpy structure. The texture can increase the friction coefficient between the shuttlecock 1 and the air during flight, simulating the aerodynamic characteristics of a traditional shuttlecock 1, so as to control the flight speed, rotation, sway, etc.

[0037] The texture of the first layer 1221 can be combined with the distribution and size of the through holes A to improve the weight distribution and air friction coefficient, further simulating the aerodynamic characteristics of a traditional badminton shuttlecock 1. The end of the feather 122 near the head 11 is an arc-shaped cone, which can guide airflow. The end of the feather 122 away from the head 11 can also be an outwardly convex cone or an inwardly concave dovetail shape, which can stabilize the direction and reduce wind resistance.

[0038] Typically, the end of the hair shaft 121 furthest from the ball head 11 is flush with or recessed 3-5mm from the tail of the hair piece 122 furthest from the ball head 11. This ensures that the hair piece 122 is supported without affecting the airflow on the hair piece 122, thus improving stability.

[0039] The thickness of the first layer 1221 is 0.1-0.6mm, and the thickness of the second layer 1222 is 0.1-0.6mm. The appropriate thickness can be selected based on the weight and strength requirements; for example, it can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc. Typically, the thickness of the first layer 1221 is thinner than that of the second layer 1222 to reduce weight. The layers are fixed by adhesive bonding or ultrasonic fixation. When fixing the first layer 1221 and the second layer 1222, one end of the bristle rod 121 can be clamped and fixed first. After fixing the first layer 1221 and the second layer 1222, the bristle rod 121 is also fixed to form the feather 12.

[0040] Preferably, combined with Figure 6 , 7 As shown, in other embodiments, the bob 122 includes two first layers 1221 and two second layers 1222 sandwiched between the two first layers 1221, with one end of the bob 121 located between any two adjacent layers. The number of second layers 1222 can be one or more. The first layers 1221 are provided on both the inner and outer sides of the bob 122, providing excellent protection and preventing easy damage to the soft second layers 1222, thus extending its service life.

[0041] The shaft 121 is a fiber tube made of resin or fiberglass. The cross-section of the shaft 121 is elliptical or circular, with the end furthest from the feather vane 122 having a larger cross-section than the end containing the vane 122, mimicking the shape of a real feather. This shaft material is 2-3 times more durable than ordinary feather shafts. The shaft 121 also matches the lifespan of the vane 12, breaking down roughly at the same time. After a certain period of impact and exposure, it breaks naturally without causing harm. Ordinary carbon fiber or nylon shafts are less prone to breakage; even after prolonged use and feather loss, the shaft remains intact, potentially causing injury to athletes.

[0042] The second embodiment of the present invention also provides a method for manufacturing a piece of pornographic material 122.

[0043] The plastic sheet is punched to form the first layer 1221;

[0044] The soft, compressible sheet is punched to form the second layer 1222;

[0045] A hair rod 121 is provided, on which a first hair piece 122 and a second hair piece 122 are attached and fixed.

[0046] The manufacturing method of the above-mentioned "flesh piece 122" is simple and convenient, which can improve production efficiency, reduce costs, and produce "flesh piece 122" with different shapes. The number of layers of "flesh piece 122" can also be selected and combined according to actual needs to meet different ball feel requirements.

[0047] In the above manufacturing method, two first layers 1221 can be sandwiched outside the second layer 1222, or one first layer 1221 can be placed on one side of the second layer 1222. Each layer can be fixed by hot melt bonding or ultrasonic bonding, or by UV adhesive bonding, and the burr 121 can be fixed.

[0048] The shapes of the first layer 1221 and the second layer 1222 can be punched out in one go, resulting in high production efficiency, high product precision, and effective guarantee of uniformity.

[0049] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0050] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
