Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a three-section artificial badminton shuttlecock. Background Technology

[0002] The main cost of badminton shuttlecocks comes from the feathers themselves. Natural feathers on shuttlecocks are made from the wing feathers of geese and ducks. The price of natural feathers is subject to the growth cycle and breeding volume of geese and ducks, so the cost of raw materials for natural shuttlecocks is relatively high. Moreover, the storage and production processes of natural feathers are more complicated, thus the processing costs are also relatively high.

[0003] Furthermore, the traditional two-section badminton shuttlecock structure is adopted: multiple feather shafts are directly inserted into the shuttlecock head, glue is injected and cured at the junction of the shuttlecock head and the shaft, then 1-3 coils are wound around the shaft, and then glue is applied and cured on the coils. This process is more complicated and the production cost is higher. Moreover, the artificial shuttlecock made of artificial feathers has a relatively smooth surface, making it difficult to accurately fix the wound coils in the corresponding positions, resulting in the inability to guarantee the diameter size of the artificial shuttlecock. In addition, the production cost is higher than that of the traditional two-section natural badminton shuttlecock. Utility Model Content

[0019] The present invention achieves the following technical advantages over the prior art:

[0020] 1. The three-section artificial badminton shuttlecock disclosed in this utility model uses artificial feathers to replace the natural feathers in the prior art. Its raw materials are industrial products, which are easy to obtain and have low production costs.

[0021] 2. The three-section artificial badminton shuttlecock uses an injection-molded artificial feather frame. The connecting cylinder of the artificial feather frame is fixedly connected to the circular groove on the end face of the shuttlecock head. The artificial feather rod of the artificial feather piece is directly inserted into the feather cavity of the artificial feather frame and fixedly connected. Its production can be completed on an automated production line, which has high production efficiency and reduces production costs.

[0022] 3. At least one reinforcing rib is connected between two adjacent feather rods. This reinforcing rib replaces the coil wound in the existing technology, ensuring the consistency of the entire three-section artificial shuttlecock, while reducing production costs by saving coils.

[0023] 4. The three-section artificial badminton shuttlecock with artificial feather frame has good consistency: Firstly, artificial feathers are industrial products, and their consistency is far superior to that of natural feathers; secondly, the artificial feather frame is an industrial product made by injection molding, so its consistency is also good; and it can ensure good consistency after the artificial feather frame and artificial feathers are connected.

[0024] 5. The number of artificial fur pieces is 4-16 pieces, and the number of fur planting rods is the same as the number of artificial fur pieces. The specific number of fur planting rods can be set as needed.

[0025] 6. The diameter of the three-section artificial badminton shuttlecock with artificial feather frame can be set as needed. The angle between the feather tube of the artificial feather frame and the central axis of the artificial connector is 15-30 degrees, and the specific angle can be set as needed. The size of this angle determines the size of the diameter of the three-section artificial badminton shuttlecock with artificial feather frame, and the size of the diameter of the three-section artificial badminton shuttlecock with artificial feather frame determines the distance of the landing point after the three-section artificial badminton shuttlecock with artificial feather frame is hit.

[0026] 7. In a three-section artificial badminton shuttlecock with an artificial feather frame, the angle between two adjacent artificial feather pieces ranges from 1 to 18 degrees, and the specific angle can be set as needed. The size of the angle between two adjacent artificial feather pieces determines the spin speed of the shuttlecock during flight; the larger the angle, the greater the spin speed. Furthermore, the structure and industrial raw materials of the three-section artificial badminton shuttlecock with an artificial feather frame ensure better consistency in its angle, and the stability of the shuttlecock is also better than that of a natural badminton shuttlecock.

[0027] 8. The injection-molded artificial hair rod has good consistency, simple process, high production efficiency and low cost.

[0028] 9. The artificial blades are made of non-woven fabric, plastic sheets, or foam sheets; the artificial bristles are integrally molded from modified plastic using an injection mold. The artificial bristles, used to connect with the artificial blades, are molded in the injection mold. Before being placed into the injection mold, the artificial blades have pre-drilled injection holes. The artificial bristles, made of modified plastic using an injection mold, form a first artificial keel and a second artificial keel on both sides of the artificial blade. Multiple pre-drilled holes are located between the first and second artificial keels, allowing the injection molding material to tightly connect them together and clamp the artificial blade. This ensures a secure bond between the artificial blades and the artificial bristles.

[0029] This production process, which involves pre-installing artificial blades in an injection mold before injection molding an artificial rod, is simple, low-cost, and ensures consistent quality when the artificial blades and artificial rod are integrated.

[0030] 10. The artificial feather shaft is made of a sheet structure formed by bonding and heating multiple layers of fiber cloth with pre-impregnated resin on the surface, and then cutting it. At least one layer of the fiber cloth with pre-impregnated resin on the surface is carbon fiber cloth, which makes it easier to control the weight of the artificial feather shaft and its strength and other mechanical properties are more in line with the needs of badminton.

[0031] 11. The artificial blade is made of two foamed sheets bonded together. The foamed sheets include, but are not limited to, foamed pearl cotton sheets. They are lightweight and low-cost, which further reduces the weight and cost of the artificial blade.

[0032] 12. Multiple airflow guide holes are distributed on the artificial blade. The airflow guide holes are located on one or both sides of the artificial blade. During the flight of the shuttlecock, some airflow can pass through the airflow guide holes, creating a pressure difference between the two sides of the artificial blade.

[0033] 13. There is no overlapping area between two adjacent artificial feather leaves, and part of the airflow can pass through the airflow guide hole, so that the artificial shuttlecock will not float during flight, improving the feel of hitting the artificial shuttlecock.

Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] The purpose of this invention is to provide a three-section artificial badminton shuttlecock to solve the problems existing in the prior art, reduce the manufacturing difficulty, thereby reduce the manufacturing cost of the shuttlecock, and ensure the consistency of the feathers.

[0046] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 8As shown, this utility model provides a three-section artificial badminton shuttlecock, including a shuttlecock head 9, an artificial feather frame 5, and multiple artificial feather pieces 1. The artificial feather frame 5 is injection molded as a single piece. One end of the artificial feather frame 5 is provided with a connecting cylinder 10, and the other end is provided with multiple feather planting rods. Each feather planting rod is evenly arranged in a frustum shape around the central axis of the artificial feather frame 5. The number of artificial feather planting rods is the same as that of the artificial feather pieces 1, which is 4-16, and the specific number of feather planting rods can be set as needed. At least one reinforcing rib 8 is connected between two adjacent feather planting rods. This reinforcing rib 8 replaces the coil wound in the prior art, ensuring the integrity of the entire three-section artificial badminton shuttlecock. Consistency is achieved, and production costs are reduced by saving coils. The feathering rod includes a feathering tube 6 and a connecting rod 7. The connecting rods 7 are all the same length, ranging from 0.1 to 14 mm. One end of the feathering tube 6 is connected to the connecting rod 7. The feathering tube 6 has a feathering cavity, the opening of which is away from the connecting rod 7 and located at the other end of the feathering tube 6. The included angle between two adjacent feathering tubes 6 is the same, ranging from 1 to 18 degrees. The specific included angle can be set as needed. The included angle between two adjacent artificial feather pieces 1 of the three-section artificial badminton shuttlecock determines the rotation speed of the three-section artificial badminton shuttlecock during flight. The larger the included angle, the greater the rotation speed. Moreover, the structure and industrial raw materials of the three-section artificial badminton shuttlecock with artificial feathering frame 5 ensure better consistency of its included angle. The stability of the three-section artificial badminton shuttlecock with artificial feathering frame 5 is also better than that of natural badminton shuttlecocks. The included angle between the central axis of the feather tube 6 and the artificial feather frame 5 is the same, which is 15-30 degrees. The specific angle can be set as needed. The size of this included angle determines the size of the opening of the three-section artificial badminton shuttlecock with the artificial feather frame 5. The size of the opening of the three-section artificial badminton shuttlecock with the artificial feather frame 5 determines the distance of the landing point after the three-section artificial badminton shuttlecock with the artificial feather frame 5 is hit, thereby realizing the setting of the opening of the three-section artificial badminton shuttlecock with the artificial feather frame 5 as needed. The artificial feather pieces 1 have the same overall length, all 40-55mm. The artificial feather piece 1 includes an artificial feather shaft 3 and an artificial blade 2. The length of the artificial feather shaft 3 is greater than the length of the artificial blade 2. Part of the structure of the artificial feather shaft 3 is combined with the artificial blade 2, and another part of the structure is exposed on the outside of the artificial blade 2. The end of the artificial feather shaft 3 away from the artificial blade 2 serves as the insertion end. The size of the insertion end matches the size of the feather implantation cavity. The insertion end is inserted into the feather implantation cavity and fixedly connected. The inner wall of the injection-molded feather implantation cavity is smooth, and the cross-sectional shape of the feather implantation cavity is adapted to the shape of the inserted insertion end. When the insertion end is inserted, it is not easy to cause its own deformation, thereby ensuring the consistency of the artificial feather pieces 1 inserted into the badminton shuttlecock. The end face of the shuttlecock head 9 is provided with a circular groove. The size of the circular groove matches the size of the connecting cylinder 10. The connecting cylinder 10 is inserted into the circular groove and fixedly connected.In summary, the three-section artificial badminton shuttlecock with artificial feather frame 5 disclosed in this utility model uses artificial feather pieces 1 to replace the natural feather pieces in the prior art. The raw materials are industrial products, which are easy to obtain and have low production costs. The artificial feather pieces 1 are not only widely available and have good consistency, but also make the three-section artificial badminton shuttlecock with artificial feather frame 5 have good consistency: First, the artificial feather pieces 1 are industrial products, and their own structural consistency is much higher than that of natural feather pieces; Second, the artificial feather frame 5 is an industrial product that is injection molded in one piece, so its own structural consistency is also good. Furthermore, by inserting the artificial feather shafts 3 of the artificial feather pieces 1 into the feather-planting cavities of the artificial feather frame 5 and connecting them firmly, the consistency of the combination between the artificial feather pieces 1 and the shuttlecock head 9 is improved, thereby ensuring the consistency of the produced artificial badminton shuttlecock.

[0048] In this embodiment, the artificial hair-planting frame 5 also includes a connecting piece, wherein the connecting piece is a thin sheet of a circle or a regular polygon, each hair-planting rod is located on one side of the connecting piece and is evenly distributed at the circumferential edge of the connecting piece in a frustum shape, and the connecting cylinder 10 is connected to the other side of the connecting piece; wherein the hair-planting rod includes a hair-planting tube 6 and a connecting rod 7, one end of the connecting rod 7 is connected to the hair-planting tube 6, and the other end is connected to the connecting piece.

[0049] In this embodiment, the artificial feather frame 5 is injection molded as a single piece. In the specific manufacturing process, a single mold is used to produce multiple products, which greatly reduces material and processing costs. Furthermore, because the three-section artificial badminton shuttlecock uses the injection-molded artificial feather frame 5, the connecting cylinder 10 of the artificial feather frame 5 is fixedly connected to the circular groove on the end face of the shuttlecock head 9, and the artificial feather rod 3 of the artificial feather piece 1 is directly inserted into the feather cavity of the artificial feather frame 5 and fixedly connected. Its production can be completed on an automated production line, which has high production efficiency and reduces manufacturing costs.

[0050] In this embodiment, a first reinforcing rib is connected between two adjacent hair-planting tubes 6, and a second reinforcing rib is connected between two adjacent connecting rods 7, so as to further ensure the structural strength of the entire artificial hair-planting frame 5.

[0051] In one specific embodiment, the artificial hair piece 1 is a combined structure consisting of artificial hair rods 3 and artificial blades 2, which are separately formed and then bonded together. On the one hand, the separate forming of the artificial hair rods 3 and artificial blades 2 allows the artificial hair rods 3 and artificial blades 2 to use different materials or processes to optimize their respective performance; on the other hand, the complex structure can be manufactured in stages, reducing the difficulty of mold making and improving the convenience of production.

[0052] In one specific embodiment, the artificial feather shaft 3 is made by laminating and curing multiple layers of fiber cloth pre-impregnated with resin, forming a sheet structure, and then cutting it. This makes it easier to control the weight of the artificial feather shaft 3, and its strength and other mechanical properties are more in line with the needs of badminton. Specifically, the fiber cloth has high tensile strength, and the resin forms a rigid matrix after curing, ensuring that the specific strength of the combined structure reaches a preset value. Furthermore, due to the multiple layers of fiber cloth, the axial tensile or torsional properties can be specifically improved by adjusting the layup direction of the fiber cloth. Overall, this significantly improves the structural strength of the artificial feather shaft 3 while ensuring its lightweight nature.

[0053] In this embodiment, at least one layer of the multi-layered fiber cloth pre-impregnated with resin is a carbon fiber cloth with a resin-impregnated surface. This makes it easier to control the weight of the artificial feather shaft 3, and its strength and other mechanical properties are more in line with the requirements of badminton. Specifically, the carbon fiber cloth has higher tensile strength and its fatigue life is much longer than that of metals or ordinary fibers. Under cyclic loading, the presence of the carbon fiber cloth can delay crack propagation, thereby improving the structural strength of the artificial feather shaft 3 and extending its service life.

[0054] In one specific embodiment, the artificial hair rod 3 is injection molded in one piece, which has good consistency, simple process, high production efficiency and low cost; in the specific preparation process, a one-mold-multiple-output method is adopted to fully reduce material cost and processing cost.

[0055] In one specific embodiment, the artificial blade 2 is made of two foam sheets bonded together, with at least one of the foam sheets being composite. The portion of the artificial shaft 3 that combines with the artificial blade 2 is placed between the two foam sheets, and the artificial shaft 3 is fixedly connected to the two foam sheets by heat bonding or adhesive bonding. The foam sheets are lightweight and low-cost, further reducing the weight of the artificial blade 2. Preferably, the foam sheets are made of foamed pearl cotton, but not limited to foamed pearl cotton. Foamed pearl cotton has a low density and a thinner overall structure, making the entire artificial blade 2 lighter and more suitable for badminton sports. Moreover, the foamed pearl cotton has good resilience, and its closed-cell structure can effectively disperse impact force. At the same time, the portion of the artificial shaft 3 that combines with the artificial blade 2 is sandwiched between the two foamed pearl cotton sheets and is firmly bonded to the two foamed pearl cotton sheets by heat bonding or adhesive bonding, thereby protecting the internal artificial shaft 3, preventing the artificial shaft 3 from being directly exposed to force, and extending its service life.

[0056] In one specific embodiment, the artificial blade 2 has multiple airflow guide holes 4 distributed on it. These airflow guide holes 4 penetrate the artificial blade 2 along its thickness direction and are located on one or both sides of the artificial feather shaft 3. On one hand, during flight, some airflow can pass through the airflow guide holes 4, creating a pressure difference between the two sides of the artificial blade 2. On the other hand, the airflow guide holes 4 can disperse airflow pressure, reducing excessive wind resistance experienced by the blade during high-speed movement. Preferably, the airflow guide holes 4 are evenly distributed on both sides of the artificial feather shaft 3, thereby ensuring the stability of the three-section artificial badminton shuttlecock during high-speed movement.

[0057] In one specific embodiment, the insertion end of the artificial hair rod 3 has a buckle, and a snap fastener is provided inside the hair implantation cavity. The insertion end is inserted into the hair implantation cavity, and the buckle snaps into the snap fastener, allowing the artificial hair piece 1 and the artificial hair implantation frame 5 to be firmly connected without glue. This eliminates the need for glue injection into the hair implantation cavity, simplifying the connection between the artificial hair piece 1 and the artificial connector. Alternatively, the insertion end and the hair implantation cavity can also be firmly connected with glue. Specifically, the insertion end is inserted into the hair implantation cavity pre-injected with glue, and the connection is completed after the glue cures.

[0058] In one specific embodiment, the artificial blade 2 is made of non-woven fabric, plastic sheet, or foam sheet; the artificial bristle rod 3 is integrally formed from modified plastic through injection molding. The portion of the artificial bristle rod 3 used to connect with the artificial blade 2, after being formed by injection molding, forms a first artificial keel 14 and a second artificial keel on both sides of the artificial blade 2. The artificial blade 2 has multiple pre-reserved through holes 11 between the first and second artificial keels, allowing the injection molding material to tightly connect the first and second artificial keels together through the pre-reserved through holes 11, thus forming a clamping effect on the artificial blade 2. Another part of the artificial bristle rod 3 is exposed outside the artificial blade 2. This production process, which involves pre-placing a plastic sheet or artificial blade 2 in the injection mold before injection molding the artificial rod, is simple, low-cost, and ensures good consistency when the artificial blade 2 and artificial bristle rod 3 are integrated.

[0059] In this embodiment, according to the size of the mold, the non-woven fabric, plastic sheet, or foam sheet is cut into the corresponding width and length, and multiple reserved through holes 11 are set at the corresponding positions at set intervals. The position of the reserved through holes 11 matches the position of the artificial hair rod in the injection molding mold. It is placed into the injection mold. The artificial hair rod 3 is integrally formed by processing modified plastic through the injection mold. The part of the artificial hair rod 3 used to connect with the non-woven fabric, plastic sheet, or foam sheet of the corresponding width and length is formed by the injection mold, and the first artificial keel 12 and the second artificial keel are formed on both sides. After the artificial hair rod is injection molded, it is cut into artificial hair pieces. This method can directly pre-place the non-woven fabric, plastic sheet, or foam sheet of the set width and length into the injection mold, and then inject the artificial hair rod, producing multiple pieces from one mold. Then it is cut into individual artificial hair pieces. This method can save the complicated work of placing artificial blades in the mold and improve production efficiency.

[0060] In this embodiment, the material type of the plastic sheet includes, but is 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; the foamed sheet includes, but is not limited to, pearl cotton sheets.

[0061] In one specific embodiment, the portions of the same artificial blade 2 located on both sides of the artificial shaft 3 along the width direction are respectively a first blade structure 12 and a second blade structure 13. Two adjacent artificial blades 2 are respectively the first artificial blade and the second artificial blade. The first blade structure 12 of the first artificial blade has a notch on the side facing away from its artificial shaft 3. A portion of the second blade structure 13 of the second artificial blade is fitted into the notch, ensuring that the first blade structure 12 and the second blade structure 13 between adjacent artificial blades 2 do not overlap, thus eliminating any overlapping area between adjacent artificial blades. Furthermore, by allowing some airflow to pass through the airflow guide hole 4, the artificial shuttlecock will not drift during flight, improving the hitting feel of the artificial shuttlecock.
