Description

Technical Field

[0001] This application relates to the field of sporting goods, and in particular to a badminton shuttlecock. Background Technology

[0002] Badminton is a popular sport enjoyed by many and widely used in both casual leisure activities and professional sporting events. With the increasing popularity and development of the sport, the demand for badminton shuttlecocks is growing daily. Both amateur enthusiasts and professional athletes require a large number of shuttlecocks to ensure their daily training and competitions.

[0003] Existing plastic badminton shuttlecocks consist of a head and a crown attached to the head. The crown includes a skirt and multiple skirt support shafts connecting the head and the skirt. To improve the shuttlecock's durability, the crown also features a reinforcing ring structure that circumferentially connects to the skirt support shafts, increasing the impact resistance of the skirt support shafts through additional support structure. However, tests have shown that even with these reinforcement measures, the durability of existing badminton shuttlecocks remains insufficient.

[0004] In response to the aforementioned technologies, the inventors need to provide a badminton shuttlecock with high durability. Utility Model Content

[0005] To further improve the durability of badminton shuttlecocks, this application provides a badminton shuttlecock.

[0006] This application provides a badminton shuttlecock, which adopts the following technical solution: A badminton shuttlecock includes a head and a crown inserted into the head. The crown includes a skirt and multiple skirt support rods connecting the head and the skirt. The crown has a reinforcing ring structure that circumferentially connects the skirt support rods. The reinforcing ring includes a first protrusion located on the outer periphery of the skirt support rods and a second protrusion located on the inner periphery of the skirt support rods.

[0007] By adopting the above technical solution, a first protrusion is set on the outer periphery of the shuttlecock skirt support shaft and a second protrusion is set on the inner periphery to form a reinforcing ring, which can increase the support strength of the shuttlecock skirt support shaft and enhance its impact resistance, thereby improving the durability of the badminton shuttlecock.

[0008] Optionally, the cross-sectional width of the first protrusion gradually increases along the direction close to the ball skirt; an air guide cone surface is formed on the outer periphery of the first protrusion.

[0009] By adopting the above technical solution, the width of the first convex section gradually increases along the direction close to the shuttlecock skirt and forms a wind-guiding cone surface on the outer periphery, which can guide the airflow, making the air resistance distribution during the flight of the badminton shuttlecock more uniform and improving the flight stability of the badminton shuttlecock.

[0010] Optionally, the first protrusion has a triangular cross-section, and the side of the first protrusion away from the ball skirt support has a first rounded corner.

[0011] By adopting the above technical solution, the first convex section is triangular and has a first rounded corner on the side away from the shuttlecock skirt support, which can further reduce wind resistance and improve smoothness, thereby enhancing the flight stability of the badminton shuttlecock.

[0012] Optionally, the cross-sectional width of the second protrusion gradually decreases along the direction close to the skirt.

[0013] By adopting the above technical solution, the width of the second convex section gradually decreases along the direction close to the skirt, which can further optimize the structure of the reinforcing ring, improve the reinforcing effect on the skirt support, and thus further enhance the durability of the badminton shuttlecock.

[0014] Optionally, the cross-section of the second protrusion is trapezoidal, and a second rounded corner is provided at both corners on the side of the second protrusion away from the ball skirt support rod.

[0015] By adopting the above technical solution, the width of the second protrusion section decreases along the direction close to the shuttlecock skirt and is trapezoidal. The second protrusion has two rounded corners at the two corners on the side away from the shuttlecock skirt support rod, which can improve the shuttlecock's durability, improve aerodynamic performance, reduce wind resistance, and avoid stress concentration that could lead to damage.

[0016] Optionally, there are two reinforcing rings, namely a first reinforcing ring and a second reinforcing ring. The first reinforcing ring is connected to the end of the ball skirt support rod away from the ball head and to the tail end of the ball skirt; the second reinforcing ring is arranged in the middle of the ball skirt support rod.

[0017] By adopting the above technical solution, two reinforcing rings are set. The first reinforcing ring connects the end of the skirt support rod away from the ball head and the tail end of the skirt, and the second reinforcing ring is arranged in the middle of the skirt support rod, which can enhance the strength of the skirt support rod from different positions.

[0018] Optionally, the thickness of the reinforcing ring is no more than 3.5 mm.

[0019] By adopting the above technical solution, the thickness of the reinforcing ring is controlled to no more than 3.5mm, which can enhance the impact resistance of the shuttlecock skirt and shaft, improve the durability of the shuttlecock, and avoid adding too much weight or affecting flight performance due to excessive thickness.

[0020] Optionally, the end of the ball skirt support rod of the ball crown is also provided with a plug-in seat for inserting the ball crown into the ball head, and the ball head has a plug-in groove that mates with the plug-in seat.

[0021] By adopting the above technical solution, the insertion seat of the crown and the insertion groove of the shuttlecock head can be matched to make the crown firmly installed on the shuttlecock head, thereby improving the overall structural stability of the badminton shuttlecock.

[0022] Optionally, the ball skirt, the ball skirt support rod, the reinforcing ring, and the plug-in seat are integrally molded into the ball crown using an injection molding process.

[0023] By adopting the above technical solution, the ball crown is made by integrally molding the ball skirt, ball skirt support rod, reinforcing ring and plug seat using injection molding process, so that all components become a whole and the structural stability is enhanced.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. A badminton shuttlecock, comprising a head and a crown inserted into the head, the crown comprising a skirt and multiple skirt support rods connecting the head and the skirt, wherein a first protrusion is provided on the outer periphery of the skirt support rods and a second protrusion is provided on the inner periphery to form a reinforcing ring, thereby increasing the support strength of the skirt support rods and enhancing their impact resistance, thus improving the durability of the badminton shuttlecock; 2. By setting two reinforcing rings, the first reinforcing ring connects the end of the skirt support rod away from the ball head and the end of the skirt, and the second reinforcing ring is arranged in the middle of the skirt support rod, the strength of the skirt support rod can be enhanced from different positions; 3. By controlling the thickness of the reinforcing ring to no more than 3.5mm, the impact resistance of the shuttlecock skirt and shaft can be enhanced, improving the shuttlecock's durability, while avoiding excessive weight increase or impact on flight performance due to excessive thickness.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a badminton shuttlecock. (Refer to...) Figure 1 A badminton shuttlecock includes a head 1 and a crown 2 inserted into the head 1. The crown 2 includes a skirt 21 and multiple skirt support rods 22 connecting the head 1 and the skirt 21. The crown 2 has a reinforcing ring 23 structure that circumferentially connects the skirt support rods 22. By setting the reinforcing ring 23 structure, the supporting strength of the skirt support rods 22 can be increased, enhancing their impact resistance and thus improving the shuttlecock's durability.

[0032] Reference Figure 2 and Figure 3 The reinforcing ring 23 includes a first protrusion 24 located on the outer periphery of the shuttlecock skirt support 22 and a second protrusion 25 located on the inner periphery of the shuttlecock skirt support 22. In this embodiment, the conical surface formed by rotating the outer periphery of the shuttlecock skirt support 22 around the axis of the shuttlecock is defined.

[0033] Reference Figure 2 and Figure 3 The cross-sectional width of the first protrusion 24 gradually increases along the direction approaching the shuttlecock skirt 21, and a guide cone surface 241 is formed on the outer periphery of the first protrusion 24. The cross-section of the first protrusion 24 is triangular, and the side of the first protrusion 24 furthest from the shuttlecock skirt support 22 has a first rounded corner 242. The guide cone surface 241 guides airflow more smoothly over the shuttlecock skirt support 22, reducing air resistance. Furthermore, the first rounded corner 242 on the side of the first protrusion 24 furthest from the shuttlecock skirt support 22 avoids unnecessary air disturbance caused by sharp corners during flight, and also reduces the risk of damage to the first protrusion 24 upon impact. The first rounded corner 242 is an arc with a small radius, the size of which is determined according to the actual size of the badminton shuttlecock and design requirements.

[0034] Reference Figure 2 and Figure 3 The cross-sectional width of the second protrusion 25 gradually decreases towards the ball skirt 21. The cross-section of the second protrusion 25 is trapezoidal, and two corners on the side of the second protrusion 25 away from the ball skirt support 22 are each provided with a second fillet 251. The trapezoidal cross-sectional structure facilitates the forming and processing of the second protrusion 25 and allows for the rational distribution of support force. The second fillet 251 is provided to avoid stress concentration. The radius of the second fillet 251 is also adjusted according to the actual situation.

[0035] Reference Figure 1 and Figure 2To further improve the durability of the shuttlecock, two reinforcing rings 23 are used: a first reinforcing ring 231 and a second reinforcing ring 232. The first reinforcing ring 231 is connected to the end of the shuttlecock skirt support 22 away from the shuttlecock head 1 and to the tail end of the shuttlecock skirt 21. The second reinforcing ring 232 is located in the middle of the shuttlecock skirt support 22. The first reinforcing ring 231 reinforces the connection between the shuttlecock skirt 21 and the shuttlecock skirt support 22, preventing the shuttlecock skirt 21 from separating from the shuttlecock skirt support 22 when hit. The second reinforcing ring 232 reinforces the middle of the shuttlecock skirt support 22, enhancing the overall bending resistance of the shuttlecock skirt support 22. The two reinforcing rings 23 work together to reinforce the shuttlecock skirt support 22 from different positions, further improving the durability of the shuttlecock.

[0036] Reference Figure 2 and Figure 3 The thickness of the reinforcing ring 23 is no greater than 3.5mm. This thickness ensures that the reinforcing ring 23 effectively strengthens the shuttlecock without making it too heavy and affecting its flight performance. In this embodiment, the thickness is defined as the dimension in the direction perpendicular to the conical surface formed by rotating the shuttlecock around its axis; the thickness of the reinforcing ring 23 is 3cm.

[0037] Reference Figure 2 and Figure 4 The end of the shuttlecock 2's skirt support 22 is also provided with a connector 26 for inserting the shuttlecock 2 onto the shuttlecock head 1. The shuttlecock head 1 has a connector groove 11 that mates with the connector 26. The connector 26 of the shuttlecock 2 mates with the connector groove 11 of the shuttlecock head 1, which allows the shuttlecock 2 to be securely installed on the shuttlecock head 1, improving the overall structural stability of the badminton shuttlecock.

[0038] Reference Figure 1 and Figure 4 Furthermore, the shuttlecock 2 is first integrally molded from the skirt 21, skirt support 22, reinforcing ring 23, and connector 26 using an injection molding process. Then, the shuttlecock head 1 is integrally molded using the same injection molding process. Finally, glue is applied to the connector groove 11 of the injection-molded shuttlecock head 1, and then the shuttlecock 2 is rotated into the shuttlecock head 1 to ensure a tight fit, making the shuttlecock head 1 and the shuttlecock 2 a single unit, thereby enhancing the overall structural stability of the badminton shuttlecock.

[0039] The implementation principle of a badminton shuttlecock according to an embodiment of this application is as follows: A badminton shuttlecock includes a head 1 and a crown 2 inserted into the head 1. The crown 2 includes a skirt 21 and multiple skirt support rods 22 connecting the head 1 and the skirt 21. By setting a first protrusion 24 on the outer periphery and a second protrusion 25 on the inner periphery to form a reinforcing ring 23, the supporting strength of the skirt support rods 22 can be increased, and its impact resistance can be enhanced, thereby improving the durability of the badminton shuttlecock.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
