Description
Technical Field
[0001] The invention relates to the field of sports goods manufacturing, in particular to a specially designed artificial feather leaf structure suitable for badminton. Background Art
[0002] Badminton is a popular sport worldwide and is suitable for people of all ages, becoming one of the most popular indoor sports. However, traditional natural badminton relies on specific duck or goose feathers, which leads to high resource consumption and adverse effects on the environment and animal populations.
[0003] Although artificial feathers offer better durability and adaptability, and can maintain stable performance under different climate conditions, they are still inferior to natural feathers in terms of hitting feel and flight characteristics. The main reason is that natural feathers can adjust their shape according to the speed of the ball, while existing artificial feathers made of a single material cannot achieve a similar deformation effect.
[0004] In order to solve the above problems, the present invention proposes a new artificial feather leaf structure and material optimization scheme. By adopting a composite method of multiple materials, the stress deformation capacity of artificial feathers during flight is improved, the hitting feel is optimized, and the flight characteristics are closer to natural badminton. Summary of the invention
[0005] The object of the present invention is to provide an artificial feather leaf, wherein the artificial feather leaf comprises a pinna and a pinna, a complex body consisting of the pinna and the pinna as a supporting skeleton, the pinna is firmly combined with the pinna, and the two together form a stable artificial feather leaf unit, so as to replace the existing structure of artificial feather leaves made of a single material.
[0006] The artificial feather leaf is composed of two or more layers; preferably, it is a three-layer structure, the upper and lower layers are vanes, the middle layer is vane veins, the upper and lower vanes are fixed by gluing, and the vanes veins are sandwiched between the two layers of vanes as a skeleton.
[0007] The material of the feather veins of the artificial feather leaf is a metal material with an elastic modulus exceeding 100 GPa, and a titanium-nickel memory alloy with superelastic performance is particularly preferred.
[0008] The veins constituting the artificial feather lobe are preferably in the shape of metal wires, but are not limited to a specific shape.
[0009] The number of metal wires constituting the veins of the artificial feather leaf is 3 to 30, and the preferred value is 3 to 15.
[0010] The diameter of the metal wire constituting the veins of the artificial feather leaf is 0.03mm to 0.3mm; the preferred value is 0.05mm to 0.15mm.
[0011] The metal wires constituting the veins of the artificial feather leaf preferably extend from the vane axis to both sides of the vane and are evenly distributed on both sides of the vane, but the distribution of the metal wires is not limited to this pattern.
[0012] The angle between the metal wire constituting the veins of the artificial feather leaf and the rachis of the vane is between 15° and 75°, and the preferred value is between 30° and 60°.
[0013] The feathers of the artificial feather leaf are made of plastic film, and the thickness of the plastic film is 0.01mm to 0.3mm; the preferred value is 0.02mm to 0.05mm.
[0014] The material of the feathers constituting the artificial feather leaves is preferably a combination of a biaxially oriented polypropylene plastic film and a polyethylene terephthalate plastic film.
[0015] Beneficial effects: The present invention improves the adaptability of artificial feathers at various flight speeds by optimizing the blade structure and material selection of artificial feathers, and can more realistically simulate the dynamic deformation of natural feathers. This improvement not only significantly enhances flight performance, but also improves stability and durability, providing users with a better sports experience. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] The following is a detailed description of the present invention in conjunction with the accompanying drawings. The following examples are implemented based on the technical solution of the present invention, and specific implementation plans and operating processes are given, but the scope of protection of the present invention is not limited to the following examples. Example
[0018] like Figure 1 , Figure 2 , Figure 3 As shown, an artificial feather leaf comprises a feather piece 1 and a feather vein 2 as a skeleton. The feather piece 1 is composed of an upper piece and a lower piece, which are bonded by glue, and the feather vein 2 is fixed between the two pieces to form a complete artificial feather leaf. The feather leaf has a small square profile.
[0019] The feather vein 2 is composed of five superelastic nickel-titanium memory alloy wires with a diameter of 0.1mm. There are three parallel nickel-titanium memory alloy wires 2-1 on the left and two parallel nickel-titanium memory alloy wires 2-2 on the right. These alloy wires are based on the feather shaft 3 and extend to the upper left and upper right respectively. The angle α between the nickel-titanium memory alloy wire 2-1 on the left and the feather shaft 3 is about 30°, and the spacing H is about 5mm; the angle β between the nickel-titanium memory alloy wire 2-2 on the right and the feather shaft 3 is about 45°, and the spacing h is about 8mm.
[0020] The vane 1 is composed of a biaxially oriented polypropylene film with a thickness of 0.03 mm and a polyethylene terephthalate film with a thickness of 0.025 mm. Example
[0021] like Figure 1 , Figure 2 , Figure 4 As shown, an artificial feather leaf comprises a feather piece 1 and a feather vein 2 as a skeleton. The feather piece 1 is composed of an upper piece and a lower piece, which are bonded by glue, and the feather vein 2 is fixed between the two pieces to form a complete artificial feather leaf. The feather leaf has a full circle profile.
[0022] The feather vein 2 is composed of seven superelastic nickel-titanium memory alloy wires. There are four nickel-titanium memory alloy wires 2-1 arranged in parallel on the left side, and three nickel-titanium memory alloy wires 2-2 arranged in parallel on the right side. These alloy wires take the feather shaft 3 as the baseline and extend to the upper left and upper right respectively. The nickel-titanium memory alloy wire 2-1 on the left side has an angle α of about 30° with the feather shaft 3, and the spacing H is about 4mm. Among the four nickel-titanium memory alloy wires 2-1 on the left side, the diameter of the bottom one is 0.05mm, and the diameters of the other three are 0.1mm. The three nickel-titanium memory alloy wires 2-2 on the right side have an angle β of about 45° with the feather shaft 3, and the spacing h is about 6mm. Among the three nickel-titanium memory alloy wires 2-2 on the right side, the diameter of the bottom one is 0.05mm, and the diameters of the other two are 0.1mm.
[0023] The vane 1 is composed of a polyethylene film having a thickness of 0.025 mm and a polyethylene terephthalate film having a thickness of 0.025 mm.
[0024] This combination of feather veins of different diameters can optimize adaptability to various flight speeds and more realistically simulate the dynamic deformation of natural feathers, thereby significantly improving flight performance. Example
[0025] like Figure 1 , Figure 2 , Figure 5 As shown, an artificial feather leaf comprises a feather piece 1 and a feather vein 2 as a skeleton. The feather piece 1 is composed of an upper piece and a lower piece, which are bonded by glue, and the feather vein 2 is fixed between the two pieces to form a complete artificial feather leaf. The feather leaf has a small square profile.
[0026] The feather vein 2 uses six 304 stainless steel wires with a diameter of 0.1 mm. Among them, three 304 stainless steel wires 2-1 extend from the upper left to the lower right in parallel, and the angle α between the 304 stainless steel wires 2-1 and the feather axis 3 is about 25°, and the spacing H is about 5 mm; the other three 304 stainless steel wires 2-2 extend from the upper right to the lower left in parallel, and the angle β between the 304 stainless steel wires 2-1 and the feather axis 3 is about 50°, and the spacing h is about 8 mm.
[0027] The vane 1 is composed of a biaxially oriented polypropylene film with a thickness of 0.05 mm and a polyethylene terephthalate film with a thickness of 0.015 mm.
[0028] This cross arrangement ensures that the veins are evenly distributed throughout the feather, giving the artificial feather leaf good flexibility and strength. Example
[0029] like Figure 1 , Figure 6 As shown, an artificial feather leaf comprises a pinna 1 and a pinna 2 as a skeleton. The pinna 1 contains only one pinna, and the pinna 2 is fixed to the pinna 1 by glue to form a complete artificial feather leaf. The outline of the feather leaf is a full circle.
[0030] The feather vein 2 is composed of five superelastic nickel-titanium memory alloy strips with a thickness of 0.1 mm and a width of 1 mm. Among them, there are three parallel nickel-titanium memory alloy strips 2-1 on the left and two parallel nickel-titanium memory alloy strips 2-2 on the right. These alloy strips extend to the upper left and upper right respectively with the feather shaft 3 as the baseline. The angle α between the nickel-titanium memory alloy strip 2-1 and the feather shaft 3 is about 20°, and the spacing H between adjacent alloy strips is about 3 mm. The angle α between the nickel-titanium memory alloy strip 2-1 and the feather shaft 3 is about 40°, and the spacing H between adjacent alloy strips is about 5 mm.
[0031] The vane 1 is a polyurethane film with a thickness of 0.03 mm.
[0032] This two-layer structure is designed to simulate the lightness and flexibility of real feathers, while ensuring that the artificial feather leaves have sufficient strength and elasticity.
