Description

Technical Field

[0001] The invention relates to the technical field of sports goods, in particular to a three-section artificial badminton. Background Art

[0002] The main cost of badminton comes from the feathers. The natural feathers on natural badminton are made from goose and duck wing feathers. The price of natural feathers is subject to the growth cycle and breeding volume of geese and ducks, so the cost of natural badminton raw materials is relatively high. In addition, the storage and production process of natural feathers are relatively complicated, so the processing cost is also relatively high.

[0003] Furthermore, the structure of the traditional two-stage badminton is adopted: the hair shafts of multiple feather pieces are directly inserted into the ball head, glue is injected and cured at the intersection of the ball head end face and the hair shaft, and then 1-3 coils are wound on the hair shaft, and then glue is coated on the coils and cured. There are many processes and the production cost is high. In addition, the surface of the artificial hair shaft of the artificial badminton composed of artificial feather pieces is relatively smooth, and the wound coils are difficult to be accurately fixed at the corresponding positions, resulting in the caliber size of the artificial badminton cannot be guaranteed. Moreover, the production cost will be higher than that of the traditional two-stage natural badminton. Summary of the invention

[0008] The overall lengths of the artificial hairs are the same, all being 40 - 55 mm. The artificial hairs include artificial hair shafts and artificial blades. The length of the artificial hair shafts is greater than that of the artificial blades. A part of the structure of the artificial hair shafts is combined with the artificial blades, and the other part of the structure is exposed outside the artificial blades. The end of the artificial hair shaft away from the artificial blade serves as a plug-in end, and the size of the plug-in end matches the size of the hair implantation cavity. The plug-in end is inserted into the hair implantation cavity and fixedly connected.

[0009] The end face of the ball head is provided with a circular groove, and the size of the circular groove matches the size of the connecting cylinder. The connecting cylinder is inserted into the circular groove and fixedly connected.

[0010] Preferably, the artificial hair is a combined structure formed by separately molding the artificial hair shaft and the artificial blade and then bonding them together.

[0019] The present invention has achieved the following technical effects compared with the prior art:

[0020] 1. The three-section artificial badminton disclosed by the present invention uses artificial hair pieces to replace the natural hair pieces in the prior art. Its raw materials are industrial products, which are convenient to obtain and have low production costs.

[0021] 2. Because the three-section artificial badminton uses an integrally injection-molded artificial hair-planting frame, the connecting cylinder of the artificial hair-planting frame is fixedly connected to the circular groove on the end face of the ball head, and the artificial hair shaft of the artificial hair piece is directly inserted into the hair-planting cavity of the artificial hair-planting frame and fixedly connected; its production can be completed on an automated production line, with high production efficiency, thereby reducing production costs.

[0022] 3. At least one reinforcing rib is connected between two adjacent hair shafts. The reinforcing rib replaces the wound coil in the prior art, ensuring the consistency of the entire three-section artificial badminton, and at the same time reducing production costs by saving coils.

[0023] 4. The three-section artificial badminton with an artificial hair-planting frame has good consistency: First, the artificial hair piece is an industrial product, and its consistency is much higher than that of natural feather pieces; second, the artificial hair-planting frame is an integrally injection-molded industrial product, so its consistency is also good; and it can ensure good consistency after the artificial hair-planting frame is connected to the artificial hair piece.

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

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

[0026] 7. The angle between two adjacent artificial hair pieces in the three - section artificial badminton with an artificial hair - planting frame is 1 - 18 degrees, and the specific angle can be set as required. Among them, the size of the angle between two adjacent artificial hair pieces in the three - section artificial badminton determines the rotation speed of the three - section artificial badminton during flight. The larger the angle, the greater the rotation speed. Moreover, the structure and industrial raw materials of the three - section artificial badminton with an artificial hair - planting frame ensure better consistency of its angle, and the stability of the three - section artificial badminton with an artificial hair - planting frame is also better than that of natural badminton.

[0027] 8. The artificial hair shaft formed by injection - molding in one piece has good consistency, simple process, high production efficiency and low cost.

[0028] 9. The artificial blade is made of non - woven fabric, plastic sheet or foamed sheet; the artificial hair shaft is integrally formed by processing modified plastic through an injection - molding die. After the part structure of the artificial hair shaft for connecting with the artificial blade is formed by the injection - molding die, there are reserved injection - through holes before the artificial blade is placed into the injection - molding die. The artificial hair shaft is integrally formed by processing modified plastic through an injection - molding die. After the part structure of the artificial hair shaft for connecting with the artificial blade is formed by the injection - molding die, the first artificial keel and the second artificial keel are formed on both sides of the artificial blade. There are multiple reserved through holes between the first artificial keel and the second artificial keel of the artificial blade, which facilitate the injection - molding material to tightly connect the first artificial keel and the second artificial keel through the reserved through holes and form a clamping effect on the artificial blade; the artificial blade and the artificial hair shaft are firmly combined;

[0029] This production process of pre - setting the artificial blade in the injection - molding die and then injection - molding the artificial shaft has a simple process and low cost. After the artificial blade and the artificial hair shaft become one, it can ensure good consistency.

[0030] 10. The artificial hair shaft is made by cutting a sheet - like structure formed by laminating and heating and curing fiber cloth with resin glue pre - impregnated on the surface of multiple layers. At least one layer of the fiber cloth with resin glue pre - impregnated on the surface of multiple layers is carbon fiber cloth with resin glue pre - impregnated on the surface, so that the gram weight of the artificial hair shaft is easier to control, and its mechanical properties such as strength better meet the requirements of badminton sports.

[0031] 11. The artificial blade is formed by laminating two foamed thin sheets. The foamed thin sheets include, but are not limited to, foamed EPE sheets, which are characterized by light weight and low cost, further reducing the gram weight and cost of the artificial blade.

[0032] 12. A plurality of air flow guiding holes are distributed on the artificial blade. The air flow guiding holes are located on one side or both sides of the artificial hair shaft. During the flight of the badminton, part of the air flow can pass through the air flow guiding holes, creating a pressure difference between the two sides of the artificial blade.

[0033] 13. There is no overlapping area between adjacent artificial hair leaves. Part of the combined air flow can pass through the air flow guiding holes, so that the artificial badminton will not float during flight, improving the hitting feel of the artificial badminton.

Specific implementation manner

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] The purpose of the present invention is to provide a three - section artificial badminton to solve the problems existing in the above - mentioned prior art, which can reduce the manufacturing difficulty, and thus can reduce the manufacturing cost of the badminton and ensure the consistency of the hair pieces.

[0046] To make the above - mentioned objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0047] As Figures 1 to 8As shown in the figure, the present invention provides a three - section artificial badminton, including a ball head 9, an artificial hair - planting frame 5 and multiple artificial hair pieces 1; the artificial hair - planting frame 5 is integrally formed by injection molding. One end of the artificial hair - planting frame 5 is provided with a connecting cylinder 10, and the other end is provided with multiple hair - planting rods. Each hair - planting rod is obliquely arranged in a frustum - like shape and evenly arranged around the central axis of the artificial hair - planting frame 5; the number of artificial hair - planting rods is the same as that of the artificial hair pieces 1, both being 4 - 16, and the specific number of hair - planting rods can be set as required; at least one reinforcing rib 8 is connected between two adjacent hair - planting rods. This reinforcing rib 8 replaces the coiled wire in the prior art, ensuring the consistency of the entire three - section artificial badminton. At the same time, by saving the wire coil, the production cost is reduced; the hair - planting rod includes a hair - planting tube 6 and a connecting rod 7. The lengths of the connecting rods 7 are the same, all being 0.1 - 14 mm. One end of the hair - planting tube 6 is connected with a connecting rod 7. The hair - planting tube 6 is provided with a hair - planting cavity, and the opening of the hair - planting cavity is far from the connecting rod 7 and is located at the other end of the hair - planting tube 6; the angles between two adjacent hair - planting tubes 6 are the same, all being 1 - 18 degrees, and the specific angle can be set as required. Among them, the angle between two adjacent artificial hair pieces 1 of the three - section artificial badminton determines the rotation speed of the three - section artificial badminton during flight. The larger the angle, the greater the rotation speed. Moreover, the structure and industrial raw materials of the three - section artificial badminton with an artificial hair - planting frame 5 ensure better consistency of its angle, and the stability of the three - section artificial badminton with an artificial hair - planting frame 5 is also better than that of a natural badminton. The angles between the hair - planting tube 6 and the central axis of the artificial hair - planting frame 5 are the same, all being 15 - 30 degrees, and the specific angle can be set as required. The size of this angle determines the size of the caliber of the three - section artificial badminton with an artificial hair - planting frame 5. The size of the caliber of the three - section artificial badminton with an artificial hair - planting frame 5 determines the distance of the landing point after the three - section artificial badminton with an artificial hair - planting frame 5 is hit, thereby realizing setting the caliber of the three - section artificial badminton with an artificial hair - planting frame 5 as required. The overall lengths of the artificial hair pieces 1 are the same, all being 40 - 55 mm. The artificial hair piece 1 includes an artificial hair rod 3 and an artificial blade 2. The length of the artificial hair rod 3 is greater than that of the artificial blade 2. A part of the structure of the artificial hair rod 3 is combined with the artificial blade 2, and another part of the structure is exposed outside the artificial blade 2. The end of the artificial hair rod 3 far from the artificial blade 2 is used as a plug - in end. The size of the plug - in end matches the size of the hair - planting cavity. The plug - in end is inserted into the hair - planting cavity and fixedly connected. Among them, the inner wall of the injection - molded hair - planting cavity is smooth, and at the same time, the cross - sectional shape of the hair - planting cavity is adapted to the shape of the inserted plug - in end. When the plug - in end is inserted, it is not easy to cause its own deformation, thereby ensuring the consistency of the inserted artificial hair pieces 1 of the badminton; the end face of the ball head 9 is provided with a circular groove, and 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.Generally speaking, for the three - section artificial badminton with an artificial hair - planting frame 5 disclosed in the present invention, it uses artificial hair pieces 1 to replace the natural hair pieces in the prior art. Its raw materials are industrial products, which are convenient to obtain and have low production costs. The artificial hair pieces 1 not only have a wide range of materials and good consistency, but also make the three - section artificial badminton with an artificial hair - planting frame 5 have good consistency. First, the artificial hair pieces 1 are industrial products, and the consistency of their own structures is much higher than that of natural feather pieces. Second, the artificial hair - planting frame 5 is an industrial product formed by injection molding in one piece, so the consistency of its own structure is also good. Furthermore, the artificial hair shafts 3 of the artificial hair pieces 1 are correspondingly inserted into the respective hair - planting cavities of the artificial hair - planting frame 5 and firmly connected, improving the consistency of the combination of the artificial hair pieces 1 and the badminton ball head 9, thus ensuring the consistency of the produced artificial badminton.

[0048] In this embodiment, the artificial hair - planting frame 5 further includes a connecting piece. The connecting piece is a thin sheet in the shape of a circle or a regular polygon. Each hair - planting shaft is located on one side of the connecting piece and is evenly distributed obliquely in a frustum - like shape at the circular edge of the connecting piece. The connecting cylinder 10 is connected to the other side of the connecting piece. And the hair - planting shaft 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 hair - planting frame 5 is formed by injection molding in one piece. In the specific preparation process, the method of multiple products from one mold is adopted to fully reduce the material cost and processing cost. And because the three - section artificial badminton uses the artificial hair - planting frame 5 formed by injection molding in one piece, the connecting cylinder 10 of the artificial hair - planting frame 5 is fixedly connected to the circular groove on the end face of the ball head 9, and the artificial hair shafts 3 of the artificial hair pieces 1 are directly inserted into the hair - planting cavities of the artificial hair - planting frame 5 and fixedly connected. Its production can be completed on an automated production line, with high production efficiency, thereby reducing the production cost.

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

[0051] In a specific embodiment, the artificial hair piece 1 is a combined structure formed by separately molding the artificial hair shaft 3 and the artificial blade 2 and then bonding them. On the one hand, the separate molding of the artificial hair shaft 3 and the artificial blade 2 allows the artificial hair shaft 3 and the artificial blade 2 to use different materials or processes to optimize their respective performances. On the other hand, complex structures can be manufactured step by step, reducing the mold difficulty and improving the production convenience.

[0052] In a specific embodiment, the artificial hair shaft 3 is made by cutting a sheet structure formed by laminating fiber cloths with resin glue pre-impregnated on the surfaces of multiple layers and then heating and curing, so that the gram weight of the artificial hair shaft 3 is easier to control, and its mechanical properties such as strength better meet the requirements of badminton sports. Specifically, the fiber cloth has the property of high tensile strength, and the resin glue forms a rigid matrix after curing, ensuring that the specific strength of the structure after the combination of the two reaches a preset value. And because there are multiple layers of fiber cloths, the axial tensile or torsional properties can be specifically improved by adjusting the laying direction of the fiber cloths. Generally speaking, the structural strength of the artificial hair shaft 3 can be fully improved, and its light weight can be ensured.

[0053] In this embodiment, at least one layer of the fiber cloths with resin glue pre-impregnated on the surfaces of multiple layers is a carbon fiber cloth with resin pre-impregnated on the surface, so that the gram weight of the artificial hair shaft 3 is easier to control, and its mechanical properties such as strength better meet the requirements of badminton sports. Specifically, the carbon fiber cloth has a higher tensile strength, and its fatigue life is much higher than that of metal or ordinary fiber. Under cyclic loading, the presence of the carbon fiber cloth can delay crack propagation, thereby improving the structural strength of the artificial hair shaft 3 and extending its service life.

[0054] In a specific embodiment, the artificial hair shaft 3 is integrally formed by injection molding, with good consistency, simple process, high production efficiency and low cost; in the specific preparation process, the method of multiple parts produced in one mold is adopted to fully reduce the material cost and processing cost.

[0055] In a specific embodiment, the artificial blade 2 is formed by laminating two foamed thin sheets, and at least one of the two foamed thin sheets is composite; the structural part where the artificial hair shaft 3 is combined with the artificial blade 2 is placed between the two foamed thin sheets, and the artificial hair shaft 3 and the two foamed thin sheets are fixedly connected by thermal lamination or adhesive lamination; the foamed thin sheet has the characteristics of light weight and low cost, further reducing the gram weight of the artificial blade 2. Among them, the preferred foamed thin sheet is a foamed EPE sheet, but it is not limited to using a foamed EPE sheet. The foamed EPE sheet has a low density and a relatively thin overall structure, making the whole artificial blade 2 lighter and more suitable for the badminton sports scenario; and the foamed EPE sheet has good resilience, and its closed-cell structure can effectively disperse the impact force. At the same time, the structural part where the artificial hair shaft 3 is combined with the artificial blade 2 is sandwiched between the two foamed EPE sheets, and is firmly combined with the two foamed EPE sheets through thermal lamination or adhesive lamination to protect the internal artificial hair shaft 3 from being directly exposed to force and extend its service life.

[0056] In a specific embodiment, a plurality of airflow guide holes 4 are distributed on the artificial blade 2, and the airflow guide holes 4 penetrate the artificial blade 2 in the thickness direction, and the airflow guide holes 4 are located on one side or both sides of the artificial hair rod 3. On the one hand, during the flight of the badminton, part of the airflow can pass through the airflow guide holes 4, so that a pressure difference is generated on the two sides of the artificial blade 2; on the other hand, the airflow guide holes 4 can disperse the airflow pressure and reduce the excessive wind resistance of the blade during high-speed movement. Preferably, the airflow guide holes 4 are evenly distributed on both sides of the artificial hair rod 3, thereby ensuring the stability of the three-stage artificial badminton during high-speed movement.

[0057] In a specific embodiment, the plug-in end of the artificial hair rod 3 has an undercut, and a buckle is provided in the hair implantation cavity. The plug-in end is implanted in the hair implantation cavity, and the undercut is snapped into the buckle, so as to firmly connect the artificial hair piece 1 and the artificial hair implantation frame 5 without the action of glue. Therefore, there is no need to inject glue into the hair implantation cavity, which simplifies the connection work between the artificial hair piece 1 and the artificial connector. Of course, as another embodiment, the plug-in end and the hair implantation cavity can also be firmly connected by glue. Specifically, the plug-in end is inserted into the hair implantation cavity pre-injected with glue, and the glue is solidified to complete the firm connection between them.

[0058] In a specific embodiment, the artificial blade 2 is made of non-woven fabric or plastic sheet or foam sheet; the artificial hair rod 3 is formed as one piece from modified plastic by injection molding; the artificial hair rod 3 is used to form a first artificial keel 14 and a second artificial keel on both sides of the artificial blade 2 after the artificial hair rod 3 is used to form a part of the structure connected to the artificial blade 2 by injection molding; the artificial blade 2 has a plurality of reserved through holes 11 between the first artificial keel 14 and the second artificial keel, which are used for the injection molding material to pass through the reserved through holes 11 to tightly connect the first artificial keel 14 and the second artificial keel together, and to form a clamping effect on the artificial blade 2; another part of the structure of the artificial hair rod 3 is exposed outside the artificial blade 2. This production process of pre-setting a plastic sheet or artificial blade 2 in an injection mold and then injection molding an artificial rod has a simple process and low cost, so that after the artificial blade 2 and the artificial hair rod 3 become one, the consistency can be guaranteed.

[0059] In this embodiment, according to the size of the mold, the non-woven fabric or plastic sheet or foam sheet is cut into corresponding widths and lengths, and a plurality of reserved through holes 11 are set at corresponding positions of the set intervals, and the positions of the reserved through holes 11 match the positions of the artificial hair rods of the injection molding mold; they are placed in the injection mold, and the artificial hair rods 3 are integrally formed by the modified plastic through the injection mold. The artificial hair rods 3 are used to connect with the non-woven fabric or plastic sheet or foam sheet of corresponding width and length. After the artificial hair rods are molded by the injection mold, a first artificial keel 12 and a second artificial keel are formed on both sides thereof; after the artificial hair rods are injection molded, they are cut into artificial hair sheets; in this way, the non-woven fabric or plastic sheet or foam sheet of set width and length can be directly pre-set into the injection mold, and then the artificial hair rods can be injection molded, so that multiple pieces can be produced from one mold, and then they can be cut into artificial hair sheets one by one. This way can save the complicated work of placing artificial leaves in the mold and improve production efficiency.

[0060] 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; the foam sheet includes but is not limited to pearl cotton sheet.

[0061] In a specific embodiment, the parts of the same artificial blade 2 located on both sides of the artificial hair rod 3 along the width direction are respectively the first blade structure 12 and the second blade structure 13, and the two adjacent artificial blades 2 are respectively the first artificial blade and the second artificial blade, and the first blade structure 12 of the first artificial blade is provided with a notch on the side away from its artificial hair rod 3, and the part of the second blade structure 13 of the second artificial blade is embedded in the notch, so that the first blade structure 12 and the second blade structure 13 between the two adjacent artificial blades 2 will not overlap, thereby making there no overlapping area between the two adjacent artificial hair blades. Further, combined with the fact that part of the airflow can pass through the airflow guide hole 4, the artificial badminton will not float during the flight, thereby improving the hitting feel of the artificial badminton.
