Description

Technical Field

[0001] The present invention relates to the technical field of sporting goods, in particular to an artificial fur piece. Background Art

[0002] The primary cost of badminton comes from the feathers. Natural badminton feathers are made from goose and duck wing feathers. The price of natural feathers is affected by the growth cycles and breeding capacity of geese and ducks, resulting in a relatively high cost for the raw materials. Furthermore, the storage and production of natural feathers are complex, leading to high processing costs.

[0003] Furthermore, natural wool blades suffer from structural inconsistency. Artificial wool blades, on the other hand, are made from industrial raw materials, which are readily available and available in unlimited quantities. Furthermore, the consistency of industrial raw materials ensures the consistency of artificial wool blades. However, the greatest challenge with artificial wool blades is the conflict between strength, elasticity, rigidity, toughness, blade stiffness, and weight. To achieve a weight that meets the requirements of badminton, the strength, elasticity, and stiffness of the blades must be insufficient. Summary of the Invention

[0004] The purpose of the present invention is to provide an artificial feather sheet to solve the problems existing in the prior art and to ensure that the entire artificial feather sheet is not only light in weight but also has elasticity, rigidity, toughness, impact strength, shear resistance, fatigue resistance and service life that are not lower than the standards of natural feather sheets.

[0005] To achieve the above-mentioned object, the present invention provides the following solution: The present invention provides an artificial hair sheet, the entire length of the artificial hair sheet is 40-76 mm, and the artificial hair sheet includes an artificial hair rod and an artificial blade;

[0006] The artificial hair rod is a rod-shaped structure formed by heating and curing at least one layer of carbon fiber cloth, the surface of which is pre-impregnated with resin, into a sheet-like structure, and then cutting it into a rod-shaped structure;

[0007] The artificial blade comprises a supporting frame, a part of the structure of the artificial hair rod is combined with the supporting frame, and the other part of the structure is exposed outside the supporting frame.

[0008] Optionally, the support frame is formed by heating and curing carbon fiber cloth including but not limited to carbon fiber cloth with pre-impregnated resin glue on the surface;

[0009] When the support frame is made of carbon fiber cloth with resin pre-impregnated surface, the artificial hair rod is attached to the carbon fiber cloth used to make the support frame and with resin pre-impregnated surface, and then becomes a whole with the support frame after heating and curing.

[0010] Optionally, a layer of patch is affixed to the surface of the support frame.

[0011] Optionally, the patch is a plastic sheet or a meltblown nonwoven fabric, the meltblown nonwoven fabric has a thickness of 0.05-2.5 mm, and the plastic sheet has a thickness of 0.01-2.5 mm.

[0012] Optionally, the patch is a foam sheet, which includes but is not limited to an EPP sheet or a composite EPP sheet. The thickness of the EPP sheet is 0.02-2.0 mm, and the thickness of the composite EPP sheet is 0.02-2.5 mm.

[0013] Optionally, a layer of meltblown nonwoven fabric is sprayed on the surface of the support frame, and the thickness of the meltblown nonwoven fabric is 0.05-2.5 mm.

[0014] Optionally, the support frame is a hollow mesh frame structure, and a thin layer is provided on the surface of at least one side of the mesh frame structure, and the thin layer includes but is not limited to a plastic film or a thin cloth.

[0015] Optionally, the surface of the mesh frame structure is connected to the thin layer by gluing or welding.

[0016] Optionally, the artificial blade has a plurality of air holes, and the air holes are located on one side or both sides of the artificial hair rod.

[0017] Optionally, the parts of the same artificial blade located on both sides of the artificial hair rod along the width direction are respectively the first blade structure and the second blade structure, and the two adjacent artificial blades on the badminton are respectively the first artificial blade and the second artificial blade. The first blade structure of the first artificial blade is provided with a notch on the side away from its artificial hair rod, and a part of the structure of the second blade structure of the second artificial blade is embedded in the notch, so as to prevent the first blade structure and the second blade structure between the two adjacent artificial blades from overlapping.

[0018] Compared with the prior art, the present invention has achieved the following technical effects:

[0019] 1. The most difficult thing about artificial feather sheets is to reconcile the contradiction between their strength, elasticity, rigidity, toughness, fatigue resistance and other characteristics with their own weight. The artificial feather rod is made of multiple layers of carbon fiber cloth with pre-impregnated resin on the surface, which is heated and cured into a sheet structure and then cut into a rod structure. That is, by using carbon fiber material to make an artificial feather rod with a carbon fiber structure, the artificial feather rod is not only light in weight, but also has impact strength, elasticity, rigidity, toughness and service life that meet or even exceed the standards of natural feather rods.

[0020] 2. On the one hand, if the artificial badminton is made of carbon fiber artificial hair shaft, the artificial blade material often cannot withstand the repeated impact of the instantaneous impact force when the shuttlecock is hit at a speed of 300 kilometers per hour, and the repeated shear force of the carbon fiber artificial hair shaft on the artificial blade material. On the other hand, if the carbon fiber hair shaft and the artificial blade are simply bonded by gluing on the surface, their strength cannot withstand the repeated impact force required when flying at a speed of 300 kilometers per hour, and their fatigue resistance is significantly reduced. Moreover, during the repeated hitting process, the bond between the carbon fiber hair shaft and the artificial blade cannot withstand the shear force of the carbon fiber hair shaft. As a result, the carbon fiber artificial hair shaft is easily peeled off from the artificial blade material, and the sharp carbon fiber hair shaft may become a sharp weapon that injures badminton players.

[0021] In the present invention, the prefabricated artificial hair rods are attached to the carbon fiber cloth used to make the support frame and the surface of which is pre-impregnated with resin glue, and then heated and cured. During the secondary molding, the pre-impregnated resin used to make the support frame flows during the heating process and can be firmly combined with the prefabricated carbon fiber artificial hair rods. Moreover, the artificial hair rods and the support frame form an integral whole, further improving the strength and impact resistance of the artificial hair rods. Such a structure effectively avoids the possibility of the isolated carbon fiber artificial hair rods causing injuries to people.

[0022] 3. The carbon fiber cloth with pre-impregnated resin glue on the surface is heated and cured, and then used as the supporting skeleton of the artificial blade, so that the artificial blade is not only light in weight, but also has impact strength, elasticity, rigidity, toughness and service life that are not lower than the standards of natural feathers.

[0023] 4. The prefabricated artificial hair rod is attached to the carbon fiber cloth used to make the support frame and pre-impregnated with resin glue on the surface. After heating and curing, after secondary molding, the part where the support frame and the artificial hair rod are combined becomes an integral part of the artificial hair rod. The two become a whole, which can reduce the cross-sectional area of this part of the artificial hair rod structure and still withstand the repeated impact of the instantaneous impact force when flying at a speed of 300 kilometers per hour.

[0024] 5. The supporting skeleton is a hollow mesh frame structure, and there is a thin layer on one side surface of the mesh frame structure. The thin layer includes but is not limited to plastic film or thin cloth, so that the entire artificial leaf is similar to the wing structure of insects such as dragonflies. The wing structure of insects such as dragonflies has many properties suitable for flying, such as high strength, good rigidity, good flexibility, good elasticity, and light weight, and has good impact resistance, shear resistance and fatigue resistance, and long service life. The present invention can imitate the wing structure of insects such as dragonflies by setting the supporting skeleton as a mesh frame structure and combining it with a thin layer, achieving a bionic effect, and making the entire artificial leaf more suitable for the characteristics and needs of badminton.

[0025] 6. The surface of the artificial blade is provided with air holes, which are located on one or both sides of the artificial hair shaft, so that part of the air flow can pass through the air holes during the flight of the artificial badminton. In this way, the artificial badminton will not float during the flight after being hit, thereby improving the hitting feel of the artificial badminton.

[0026] 7. Furthermore, there is no overlapping area between two adjacent artificial feather pieces, which can further ensure that the artificial badminton will not float during the flight, and significantly improve the hitting feel of the artificial badminton. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The purpose of the present invention is to provide an artificial feather sheet to solve the problems existing in the prior art and to ensure that the entire artificial feather sheet is not only light in weight but also has elasticity, rigidity, toughness, impact strength, shear resistance, fatigue resistance and service life that are not lower than the standards of natural feather sheets.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 5 As shown, the present invention provides an artificial hair sheet, wherein the artificial hair sheet 1 has an overall length of 40-76 mm and includes an artificial hair rod 3 and an artificial blade 2. The artificial hair rod 3 is formed by heating and curing a sheet-like structure of carbon fiber cloth including at least one layer of pre-impregnated resin on the surface, and then cutting it into a rod-like structure. This makes it easier to control the gram weight of the artificial hair rod 3, and its strength and other mechanical properties are more in line with the requirements of badminton. The fiber composite material has high tensile strength, and the resin glue forms a rigid matrix after curing, ensuring that the specific strength of the structure after the two are combined reaches a preset value. Moreover, due to the presence of multiple layers of fiber cloth, the axial tensile or torsional resistance can be specifically improved by adjusting the angle between the fiber filaments of each layer of fiber cloth. Overall, the structural strength of the artificial hair rod 3 can be fully improved while ensuring its lightweight.

[0038] The artificial blade 2 includes a support frame 5, which is composed of a carbon fiber cloth including a layer of pre-impregnated resin on the surface. The portion of the structure where the artificial hair rod 3 is connected to the support frame 5 is first bonded to at least one layer of pre-impregnated resin on the surface of the carbon fiber cloth, and the other portion of the structure is exposed on the outside of the support frame 5. The two are heated together at a high temperature, and after the resin is cured, the artificial hair rod 3 and the support frame become a whole. The length of the artificial hair rod 3 is greater than that of the artificial blade 2, and part of the structure of the artificial hair rod 3 is exposed on the outside of the support frame 5, that is, exposed on the outside of the entire artificial blade 2.

[0039] In this embodiment, artificial feather sheets 1 are used to replace the natural feather sheets in the prior art. The raw materials for the artificial feather sheets are industrial products such as carbon fiber, which are easy to obtain and have low production costs. The artificial feather sheets 1 are not only widely available, but also, because they are industrial products, their structural consistency is much higher than that of natural feather sheets, thereby ensuring the consistency of the produced artificial shuttlecocks.

[0040] In summary, the most difficult aspect of the artificial hair sheet 1 is to reconcile the contradiction between its strength, elasticity, rigidity, toughness, fatigue resistance, service life and other characteristics with its own weight. The artificial hair rod 3 disclosed in the present invention is a rod-shaped structure formed by heating and curing multiple layers of carbon fiber cloth with resin pre-impregnated on the surface into a sheet structure, which is then cut. That is, by using carbon fiber composite materials to produce an artificial hair rod 3 with a carbon fiber structure, the artificial hair rod 3 is not only lightweight, but also has impact strength, elasticity, rigidity, toughness, service life and fatigue resistance that are not lower than the standards of natural feather rods. Furthermore, in the present invention, as the supporting skeleton 5 of the artificial blade 2, carbon fiber cloth with resin pre-impregnated on the surface is used, which is heated and cured, so that the artificial blade 2 is not only lightweight, but also has impact strength, elasticity, rigidity, toughness, fatigue resistance and service life that are not lower than the standards of natural feather blades. Therefore, the prefabricated artificial hair rod 3 is attached to the carbon fiber cloth used to make the support frame 5 and the surface of which is pre-impregnated with resin glue, and is heated and cured. After secondary molding, the support frame 5 and the artificial hair rod 3 become an integral whole, which can reduce the cross-sectional area of this part of the artificial hair rod 3, thereby reducing the gram weight of this part of the structure, and further reducing the gram weight of the artificial hair sheet, while still being able to withstand the repeated impact of the instantaneous impact force when flying at a speed of 300 kilometers per hour.

[0041] In a specific embodiment, the support frame 5 is made of a carbon fiber cloth with a layer of resin pre-impregnated on the surface, which is heated and cured; the artificial hair rod 3 is bonded to the carbon fiber cloth with resin pre-impregnated on the surface used to make the support frame 5, and after being heated and cured, it becomes an integral part of the support frame 5. It should be noted that the gram weight of the existing artificial hair sheet is very sensitive to the performance of the artificial badminton. The durability of the artificial badminton requires the artificial hair sheet 1 to have a certain strength, and the strength of the artificial hair sheet 1 is largely determined by the gram weight of the artificial hair sheet 1. The lighter the gram weight, the higher the performance requirements of the material. For example, when melt-blown non-woven fabric is used as the material for artificial blades, its own stiffness cannot meet the high-speed movement requirements of badminton. During the process of being hit, or after being hit several times, it cannot withstand the instantaneous impact force when the artificial badminton is hit at a speed of 300 kilometers per hour. Artificial blades made of melt-blown non-woven fabric are prone to curling, which in turn leads to the performance of the artificial badminton being unable to be guaranteed.

[0042] Therefore, in this embodiment, the prefabricated artificial hair rod 3 is attached to the carbon fiber cloth used to make the support frame 5 and the surface of which is pre-impregnated with resin glue, and is heated and cured. During the secondary molding, the pre-impregnated resin used to make the support frame 5 flows during the heating process and can be firmly combined with the prefabricated artificial hair rod 3 after curing; and the artificial hair rod 3 and the support frame 5 form a whole, further improving the overall strength and impact resistance of the artificial hair piece; the combination of the carbon fiber hair rod and the artificial blade 2 in the prior art is only bonded by adding glue on the surface, and its firmness cannot withstand the repeated impact of the instantaneous impact force when flying at a speed of 300 kilometers per hour, and its fatigue resistance is significantly reduced. Moreover, during the repeated impact, the joint between the carbon fiber hair rod and the artificial blade 2 cannot withstand the shear force of the carbon fiber hair rod.

[0043] In one embodiment, a patch is attached to the surface of the support frame 5. In this embodiment, the patch is a meltblown nonwoven fabric or a plastic sheet. This not only improves the durability and stiffness of the materials attached to the carbon fiber frame, but also ensures that the weight of the artificial hair meets the requirements of artificial badminton. Preferably, the thickness of the meltblown nonwoven fabric is 0.05-2.5 mm, and the thickness of the plastic sheet is 0.01-2.5 mm.

[0044] In this embodiment, the material types of the plastic sheet include, but are not limited to, low-density polyethylene (LDPE), linear low-density polyethylene (LL-DPE), polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), acrylonitrile-butadiene-styrene copolymer (ABS), polyamide (PA), extruded polyethylene (EPE), and BOPP film.

[0045] In this embodiment, the patch is a foam sheet, which has the characteristics of light weight and low cost, and can further reduce the gram weight of the artificial blade 2; the biggest disadvantage of the foam sheet is that its shear resistance and stiffness are both weak; the foam sheet includes but is not limited to an EPP sheet or a composite EPP sheet, the foam EPP sheet has a low density and a thin overall structure, which makes the entire artificial blade 2 more lightweight and can be effectively applied to badminton sports scenes; and the foam EPP sheet has good resilience, and its closed-cell structure can effectively disperse impact force; in this embodiment on the support skeleton 5, the support skeleton serves as a support for the patch on its surface, which not only improves the shear resistance, durability and stiffness of the patch attached to its surface, and improves its service life, but also ensures the gram weight of the artificial hair sheet 1, and it can meet the performance requirements of artificial badminton; and preferably, the thickness of the EPP sheet is 0.02-2.0mm, and the thickness of the composite EPP sheet is 0.02-2.5mm.

[0046] In a specific embodiment, a layer of meltblown nonwoven fabric is sprayed on the surface of the support frame 5, and the thickness of the meltblown nonwoven fabric is 0.05-2.5 mm.

[0047] In a specific embodiment, the support frame 5 is a hollow mesh frame structure, which further reduces the weight of the support frame, thereby effectively reducing the overall weight of the artificial hair piece; a thin layer is provided on one side surface of the mesh frame structure, the thin layer includes but is not limited to a plastic film or a thin cloth, the plastic film includes but is not limited to a PE film, the PE film is not only thin and light, but also has good toughness, elasticity, and ductility, and a long service life; the thin cloth is a thin and light cloth, such as silk, the thickness of the plastic film is 0.01-2.0 mm, and the thickness of the thin cloth is 0.02-2.0 mm; so that the entire artificial leaf 2 is similar to the wing structure of a dragonfly, and the wing structure of insects such as dragonflies has The present invention has many properties suitable for flight, such as high strength, good rigidity, good flexibility, good elasticity, and light weight. By setting the support frame as a mesh frame structure and combining it with a thin layer, it can imitate the wing structure of insects such as dragonflies, achieving a bionic effect, and making the entire artificial blade 2 more suitable for the characteristics and needs of badminton. Furthermore, a thin cloth is attached to the surface of the hollow frame. During the flight of the artificial badminton, air can also semi-permeate through the thin cloth. This semi-permeability has similar functions to natural feathers. Preferably, the mesh frame structure is connected to the thin layer on one side of its surface by gluing or welding to ensure the connection strength between the mesh frame structure and the thin layer. Preferably, the mesh frame structure has a layer of plastic film on both surfaces, and the two layers of plastic film are welded to each other to achieve a strong connection with the mesh frame.

[0048] In this embodiment, through holes are opened on the supporting frame 5 to further reduce the weight of the supporting frame 5 .

[0049] In a specific embodiment, the artificial hair rod 3 is made of, including but not limited to, nano-carbon fiber composite materials, to further reduce the weight and improve various properties of the artificial hair rod.

[0050] In a specific embodiment, the support frame 5 is made of, including but not limited to, nano-carbon fiber composite materials, to further reduce the weight and improve various properties of the artificial blade.

[0051] In one specific embodiment, the artificial blade 2 has multiple air holes 4 located on one or both sides of the artificial hair shaft 3. These air holes 4 extend through the thickness of the artificial blade 2. This allows some airflow to pass through the holes 4 during flight, creating a pressure differential across the blade 2. Furthermore, the holes 4 disperse airflow pressure, reducing excessive wind resistance experienced by the blade during high-speed motion. Preferably, the air holes 4 are evenly distributed on both sides of the artificial hair shaft 3, thereby ensuring the stability of the artificial badminton during high-speed motion. This prevents the artificial badminton from drifting during flight after being struck, improving the feel of the shot.

[0052] In one specific embodiment, the portions of the same artificial blade 2 located on either side of the artificial hair shaft 3 along the width direction are respectively a first blade structure and a second blade structure. Adjacent artificial blades 2 on the same badminton shuttlecock are respectively the first and second artificial blades. A notch 6 is provided on the side of the first blade structure of the first artificial blade facing away from the artificial hair shaft 3. Part of the second blade structure of the second artificial blade fits within the notch 6, thereby preventing the first and second blade structures of the two adjacent artificial blades 2 from overlapping. This ensures that there is no overlapping area between the adjacent artificial hair pieces. Furthermore, by allowing some airflow to pass through the air holes 4, the artificial badminton shuttlecock can be prevented from floating during flight, significantly improving the feel of the shuttlecock.

[0053] Adaptive changes based on actual needs are all within the scope of protection of the present invention.

[0054] It should be noted that it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
