Description

Technical Field

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

[0002] The shuttlecock head is the most important part of a badminton shuttlecock. Currently, a common method involves inserting the shaft of the feather directly into the shuttlecock head, requiring a hole to be drilled at an angle into the flat surface of the head before inserting the feather shaft. However, the hole drilled on the shuttlecock head is round, while the shaft of a natural feather is nearly square. Furthermore, the natural feather shaft is a hollow tube of keratinized protein, possessing a certain degree of elasticity and filled with flocculent sponge. Moreover, the insertion end of the shaft is the thickest part of the feather. When the square hollow tube is inserted into the round hole on the shuttlecock head, it easily causes slight deformation of the square hollow tube, resulting in inconsistent insertion of the feather.

The insertion tube is arranged obliquely and evenly around the periphery of the second cylinder or the outer periphery of the annular sheet in a frustum shape.

[0020] Preferably, the material of the ball head includes, but is not limited to, natural cork, synthetic cork, and foam material.

[0021] The present invention achieves the following technical advantages over the prior art:

[0022] 1. The insertion part is injection molded in one piece, with multiple parts produced from a single mold, which greatly reduces material and processing costs;

[0023] 2. The shuttlecock's feather shaft is inserted into the insertion cavity of the insertion tube. The spacing, size, and angle between the insertion tube and the central axis of the shuttlecock head are all consistent to ensure the uniformity of the entire shuttlecock.

[0024] 3. The injection-molded insertion cavity is smooth, and the cross-sectional shape of the insertion cavity matches the shape of the inserted feather shaft. When the feather shaft is inserted, it is not easy to cause deformation of the feather shaft, thus ensuring the consistency of the inserted feathers in the shuttlecock.

[0025] 4. Hollowing out the injection molded part reduces its weight to ensure the overall weight of the ball head; the first reinforcing rib is used to ensure strength.

[0026] 5. Only the head of the badminton shuttlecock is made of solid elastic material, which reduces the amount of material used to ensure the elasticity of the head, thereby reducing the weight of the head and lowering the cost.

[0027] 5.1 Natural cork is chosen as the elastic material. Natural cork is the elastic material that best meets the standards for badminton shuttlecock use. Of course, the cost is also particularly high. Natural cork is only used in the head of the shuttlecock to reduce the cost of using cork.

[0028] 5.2 The elastic material is made of synthetic cork. Synthetic cork is made by mixing and curing glue with natural cork chips. Because it is heavy, it makes the shuttlecock head too heavy. Synthetic cork is only used in the head of the hitting part of the shuttlecock, which greatly reduces the proportion of synthetic cork material and thus allows the weight of the shuttlecock head to be controlled within the range that is suitable for badminton.

[0029] 5.3 The elastic material is made of foam. The density of the foam material in the shuttlecock head can be foamed according to the elasticity and weight of the shuttlecock head to ensure that the elasticity and weight of the shuttlecock head meet the requirements of badminton.

[0030] 6. The angle between the insertion tube and the central axis of the shuttlecock head is 15 to 30 degrees. The angle between the insertion tube and the central axis of the shuttlecock head determines the taper of the entire shuttlecock. The larger the angle, the larger the taper, and the larger the diameter of the shuttlecock made of multiple feathers with the same curvature. Conversely, the smaller the angle, the smaller the diameter. The diameter of the shuttlecock is an important factor in determining the distance of the landing point during the flight of the shuttlecock. The larger the diameter, the greater the wind resistance, and the closer the landing point.

[0031] 7. By setting the mounting groove, the first cylinder and its base plate, the contact surface between the insertion part and the striking part is increased. The base plate can bear the force from the striking part. At the same time, the reaction force from the insertion part to the striking part is also mainly transmitted through the base plate, which reduces the pressure generated during the striking process. Moreover, the base plate can increase the bonding surface area between the insertion part and the striking part by adding glue, thereby improving the firmness between the insertion part and the striking part.

[0032] 8. The structure of the insert tube is embedded in the connecting part of the shuttlecock head, and the two are fitted together; and the bottom plate of the first cylinder extends into the inside of the shuttlecock head, causing the center of gravity of the shuttlecock to sink towards the head, thereby making the center of gravity of the entire shuttlecock closer to the head, so as to improve the turning speed of the shuttlecock after being hit, which is difficult to achieve with existing shuttlecocks.

[0033] 9. The bottom plate of the first cylinder is in direct contact with the head of the ball, and can directly withstand the impact force from the head of the ball.

[0034] 10. The outer side of the first cylinder near the ball head has multiple outwardly extending buckles. The connecting part is a hollow cylinder. The inner wall of the connecting part has an annular cut. Each buckle is inserted into the annular cut, thereby making the first cylinder and the connecting part firmly connected. This is used to ensure a firm connection between the insertion part and the striking part without the action of glue.

[0035] 11. The bottom plate of the first cylinder has a first central hole through its axis, and the striking part has a second central hole through its axis. The second central hole is connected to the first central hole. During the flight of the shuttlecock, the airflow can pass through the first and second central holes, thereby reducing wind resistance. The size of the first and second central holes can adjust the wind resistance. A whistle can also be embedded in the first or second central hole, which can make the shuttlecock make a sound during flight, thereby increasing the enjoyment of badminton.

[0045] 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.

[0046] The purpose of this invention is to provide a badminton shuttlecock head that solves the problems existing in the prior art, improves the consistency of feather insertion into the shuttlecock head, and ensures the consistency of the badminton shuttlecock.

[0047] 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.

[0048] like Figures 1 to 7As shown, this utility model provides a badminton shuttlecock head, including a connector and a hitting part. The connector is injection molded in one piece, allowing for multiple production runs from a single mold, significantly reducing material and processing costs. One end of the connector has multiple insertion tubes 1, ranging from 3 to 17 in number. Each insertion tube 1 has the same size and shape. Each insertion tube 1 is arranged obliquely and evenly on the outer periphery of the connector's axis in a frustum shape. Each insertion tube 1 has an insertion cavity for inserting a feather shaft, preferably with a depth of 2-20 mm. The injection-molded insertion cavity is smooth, and its cross-sectional shape matches the shape of the inserted feather shaft, preventing deformation during insertion and ensuring the consistency of the inserted feathers on the shuttlecock. Preferably, the insertion cavity and the feather shaft are firmly connected by adhesive. The insertion tube 1 includes an open end and a connecting end, with the open end being away from the striking part. The other end of the insertion tube is coaxially fitted with an installation end. The striking part includes a shuttlecock head 8 and a connecting part 7. The shuttlecock head 8 has a hemispherical or spherical notch structure, and the connecting part 7 has a cylindrical structure. The connecting part 7 is coaxially and fixedly connected to the installation end. The distance between each insertion tube 1 and the plane of the shuttlecock head 8 is the same. The angle between each insertion tube 1 and the central axis of the shuttlecock head 8 is the same, and the angle is 15-30 degrees. The angle between the insertion tube 1 and the central axis of the shuttlecock head 8 determines the taper of the entire shuttlecock. The larger the angle, the larger the taper, and the larger the diameter of the shuttlecock made of multiple feathers with consistent bow angles, and vice versa. The landing point of the shuttlecock is the distance between the hitting point and the landing point after the shuttlecock has traveled a certain distance after being hit. The diameter of the shuttlecock is a crucial factor determining the distance of the landing point. The larger the diameter, the greater the wind resistance and the closer the landing point; the included angle between two adjacent insertion tubes 1 is 1~18 degrees; in this utility model, the shuttlecock's feather shaft is inserted into the insertion cavity of the insertion tube 1. The spacing, size, and included angle between the insertion tubes 1 and the central axis of the shuttlecock head are all consistent. In summary, this utility model connects the hitting part and each feather shaft through the insertion part, and the insertion part is integrally molded by injection molding. The arrangement structure of each insertion tube 1 is optimized to ensure the consistency of the distribution of each insertion tube 1. Then, after the feather shaft of the feather passes through each insertion port, it is inserted into each insertion cavity and firmly connected, which improves the consistency of the feather insertion into the shuttlecock head, thereby ensuring the consistency of the produced shuttlecock. This solves the problem of the existing technology of directly opening holes in the shuttlecock head and inserting the feather shaft into the openings in the shuttlecock head, resulting in feather shaft deformation and poor consistency.

[0049] In one specific implementation, such as Figure 2As shown, a connecting piece 3 is provided between each plug tube 1 and the mounting end of the plug-in part; the plug tube 1 is located on one side of the connecting piece 3 and arranged around the periphery of the connecting piece 3, the open end of the plug tube 1 is away from the connecting piece 3, and the connecting end of the plug tube 1 is connected to the connecting piece 3; the mounting end is located on the other side of the connecting piece 3, and a first cylinder 5 coaxial with it is provided on the mounting end; the end face of the connecting part 7 is provided with a mounting groove 9 coaxial with the first cylinder 5, and the mounting groove 9 is coaxial with the connecting part 7; the size of the first cylinder 5 matches the size of the mounting groove 9, the first cylinder 5 is inserted into the mounting groove 9 and fixedly connected.

[0050] In this embodiment, as a preferred embodiment, such as Figure 1 As shown, the connecting ends of each insertion tube 1 are connected to the connecting piece 3 via a connecting rod 2; the insertion tube 1 and the connecting rod 2 together form an insertion rod, and a first reinforcing rib 10 connects adjacent insertion rods. The injection molded part is hollowed out to reduce the weight of the injection molded part to ensure the overall weight of the ball head, and the first reinforcing rib 10 is used to ensure strength.

[0051] In this embodiment, as another preferred option, such as Figure 3 As shown, the connecting end of each insertion tube 1 is directly connected to the connecting piece 3, and a first reinforcing rib 10 is connected between two adjacent insertion tubes 1, and a second reinforcing rib 11 is connected between the insertion tube 1 and the connecting piece 3.

[0052] In one specific implementation, such as Figure 4 , Figure 5 and Figure 6 As shown, the connector is integrally formed, and a portion of the structure of each connector 1 is embedded in the connecting portion 7. A receiving cavity is formed inward along the axis of the connecting portion 7, and a portion of the structure of the mounting end is embedded in the receiving cavity. The size of the receiving cavity matches the size of the portion of the mounting end embedded therein and is fixedly connected. A portion of the structure of the connector 1 is completely embedded in the connecting portion 7 of the shuttlecock head 8, and the two are fitted together. In the embodiment where the bottom plate 6 of the first cylinder 5 extends into the inside of the shuttlecock head, the center of gravity of the shuttlecock sinks towards the shuttlecock head 8, thereby bringing the center of gravity of the entire shuttlecock closer to the shuttlecock head, thus increasing the turning speed of the shuttlecock after being hit, which is difficult to achieve with existing shuttlecocks.

[0053] In one specific embodiment, the mounting end includes a first cylinder 5 and a second cylinder 4 coaxial with it. The diameter of the second cylinder 4 is larger than that of the first cylinder 5. There is an annular thin sheet between the first cylinder 5 and the second cylinder 4. The insertion tube 1 is arranged obliquely and evenly around the periphery of the second cylinder 4 or the outer periphery of the annular thin sheet in a frustum shape. The end face of the connecting part 7 is provided with a mounting groove 9 coaxial with the first cylinder 5. The size of the first cylinder 5 matches the size of the mounting groove 9. The first cylinder 5 is inserted into the mounting groove 9 and fixedly connected. The connecting part 7 of the striking part includes a first connecting part and a second connecting part. The first connecting part is connected to the ball head. The second connecting part is located at a position away from the ball head 8 of the first connecting part. The outer diameter of the second connecting part is smaller than the outer diameter of the first connecting part. The outer diameter of the second connecting part matches the inner diameter of the second cylinder 4 and is inserted into the second cylinder 4 and fixedly connected.

[0054] In one specific implementation, such as Figure 7 As shown, the outer side of the first cylinder 5 near the ball head 8 has multiple outwardly extending buckles 12. The connecting part 7 is a hollow cylinder, and the size of the hollow core of the hollow cylinder matches the size of the first cylinder 5. Alternatively, the hollow cylinder has a hollow structure. An annular cut 13 is provided on the inner wall of the connecting part 7 near the ball head 8. Each buckle 12 is fastened into the annular cut 13, so that the first cylinder 5 and the connecting part 7 are firmly connected. The bottom plate 6 of the first cylinder 5 is located at the bottom of the first cylinder 5, and the bottom plate 6 is directly attached to the end face of the ball head 8. The insertion part and the striking part are firmly connected without the use of glue. The design incorporates an mounting groove 9, a first cylinder 5, and a base plate 6 to increase the contact area between the insertion part and the striking part. The base plate 6 can absorb the force from the striking part, and the reaction force from the insertion part to the striking part is also primarily transmitted through the base plate 6, reducing the pressure generated during the striking process. Furthermore, the base plate 6 can increase the bonding area between the insertion part and the striking part by adding adhesive, thereby improving the strength between them. The base plate 6 of the first cylinder 5 is in direct contact with the ball head 8, directly absorbing the impact force from the ball head 8.

[0055] In one specific embodiment, the bottom plate 6 of the first cylinder 5 has a first central hole extending through its axis, and the striking part has a second central hole extending through its axis, the second central hole communicating with the first central hole. During the flight of the shuttlecock, airflow can pass through the first and second central holes, thereby reducing wind resistance. The size of the first and second central holes can adjust the wind resistance. A whistle can also be embedded in the first or second central hole, which can make the shuttlecock make a sound during flight, thereby enhancing the enjoyment of badminton.

[0056] In one specific embodiment, the material of the shuttlecock head 8 includes, but is not limited to, natural cork, synthetic cork, and foam material. Only the shuttlecock head 8 uses a solid elastic material, reducing the amount of material used to ensure the elasticity of the shuttlecock head, thereby reducing its weight and cost. In one embodiment, natural cork is chosen as the elastic material. Natural cork is the most suitable elastic material for badminton use, although it is also particularly expensive. Using natural cork only in the shuttlecock head 8 reduces the cost of cork. In another embodiment, synthetic cork is used as the elastic material. Synthetic cork, being made by mixing and curing natural cork chips with glue, tends to be heavier, leading to an overweight shuttlecock head. Using synthetic cork only in the hitting part of the shuttlecock head 8 significantly reduces the proportion of synthetic cork material, thus keeping the weight of the shuttlecock head within the range suitable for badminton. In yet another embodiment, foam material is used as the elastic material. The density of the foam material in the shuttlecock head 8 can be adjusted according to the elasticity and weight of the shuttlecock head 8 to ensure that the elasticity and weight of the shuttlecock head meet the requirements of badminton.

[0057] In one specific embodiment, the ball head 8 of the striking part is made of transparent elastic material, and further, the connecting part 7 of the striking part is also made of transparent material; a second central hole is provided through the axis of the striking part along its axial direction, and a light-emitting diode is installed at the second central hole. The light-emitting diode can emit light to the outside through the ball head 8 and the connecting part 7 of the striking part.

[0058] In one specific embodiment, the ball head 8 of the striking part is painted or coated with a thin layer of PU foam to protect the ball head from damage when repeatedly struck.

[0059] In one specific embodiment, the outside of the striking part is covered with a layer of PU leather, sprayed with paint, or sprayed with a thin layer of PU foam to protect the striking part from damage when repeatedly struck.

[0060] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
