Description

Technical Field

[0001] This application relates to the field of sports equipment technology, and more particularly to a split-type badminton shuttlecock. Background Technology

[0002] Badminton is a popular sport. Current badminton manufacturing processes suffer from the following problems: Traditional manufacturing processes for shuttlecocks made from natural or synthetic feathers typically involve drilling holes in the shuttlecock head, inserting individual feathers into these holes, and then weaving and securing the feathers into the shuttlecock skirt using thread and glue. This complex process includes multiple independent steps such as feather insertion, threading, and glue application. It is not only inefficient and time-consuming, but the accumulated errors in each step lead to poor consistency and low yield of the final product. Furthermore, it requires significant manual correction of the shuttlecock skirt, substantially increasing production costs.

[0003] Another type of integrally injection-molded plastic badminton shuttlecock typically has its skirt fixed to the head via a connecting ring at the bottom, using adhesive or snap-fit ​​methods. However, in order to control the overall weight, this connection structure often lacks sufficient rigidity and strength, causing the skirt to easily deform excessively during high-speed flight, affecting flight performance, and even leading to the skirt detaching from the head during use.

[0004] In addition, some technical solutions have proposed designing the shuttlecock head as a complex structure consisting of an external shuttlecock head component and an internal embedded component, which clamps the base of the shuttlecock skirt. However, these solutions often rely on complex mechanical interlocking structures such as slots and locking flanges for fixation. This not only requires high precision in the machining of molds and parts, increasing manufacturing costs, but may also fail to provide uniform and reliable clamping force during assembly, affecting the stability and concentricity of the connection. Therefore, there is an urgent need in this field for a novel badminton shuttlecock structure and manufacturing method to simplify the production process, improve production efficiency and product consistency, and ensure the reliability and stability of the connection between the shuttlecock skirt and the shuttlecock head. Utility Model Content

[0005] The purpose of this application is to address the problems of complex and inefficient manufacturing processes, poor product consistency, high labor costs, and insufficient rigidity, low strength, or complex structure in existing badminton skirt and head connection methods, and to provide a badminton shuttlecock with simple structure, reliable connection, simplified process, high production efficiency, and high product quality.

[0006] To achieve the above objectives, this application provides a badminton shuttlecock, including a skirt and a head;

[0007] The ball head includes an outer shell and a core, wherein the outer shell has a receiving cavity for accommodating the lower end of the ball skirt; the core is adapted to the receiving cavity of the outer shell.

[0008] The ball skirt includes a ball skirt body and a support part; the support part is distributed on the ball skirt body and plays a structural support role.

[0009] The lower end of the ball skirt is clamped and glued between the outer shell and the inner core.

[0010] In one possible implementation, the receiving cavity is a frustoconical hole, and the core body is a frustoconical plug adapted to the frustoconical hole; the lower end of the ball skirt is fixed between the outer shell and the core body by compression and bonding through the conical hole.

[0011] In one possible implementation, the outer shell is a ball joint and the inner core is a ball plug;

[0012] In one possible implementation, the skirt body is composed of a plurality of feathers or a single, integrally formed skirt body.

[0013] In one possible implementation, the feather comprises a blade and a shaft.

[0014] In one possible implementation, the skirt body is composed of a plurality of natural or artificial feathers.

[0015] In one possible implementation, the support includes at least one support ring and / or a set of support rods;

[0016] The support rod is provided with a hole or slot for inserting the natural or artificial feathers.

[0017] The support rings are distributed on the shafts or support rods of the feathers; the support rings are used to connect the plurality of natural or artificial feathers into a frustum shape.

[0018] In one possible implementation, the natural or artificial feather passes through the insertion hole or slot of the support rod, and the lower end of the natural or artificial feather is clamped and fixed between the outer shell and the core.

[0019] In one possible implementation, the support portion includes a first support ring, a second support ring, and / or a third support ring; the first and second support rings are distributed on the ball skirt body; the third support ring is connected to the lower end of the ball skirt body and is clamped and bonded between the outer shell and the inner core.

[0020] In one possible implementation, the ball skirt is a component integrally molded from a polymer foam material, and the lower part of the ball skirt has an integrally molded conical ring that is clamped between the outer shell and the inner core.

[0021] This application also provides a method for manufacturing a badminton shuttlecock, comprising the following steps:

[0022] Prefabricate a trumpet-shaped ball skirt body or ball skirt;

[0023] The main body of the shuttlecock skirt or the lower end of the shuttlecock skirt is placed in the receiving cavity of the outer shell, which is used to form part of the head of the shuttlecock;

[0024] The core body is pressed into the receiving cavity, and the lower end of the ball skirt body or the ball skirt is clamped and glued between the outer shell and the core body through the cooperation of the core body and the outer shell to form the ball head.

[0025] Compared with existing technologies, this application has the following advantages: First, the badminton shuttlecock of this application includes a separate skirt and a head, thus adopting a "prefabricated skirt + separate head clamping and fixing" model, completely eliminating the time-consuming and problem-prone processes of feather insertion, stringing, and gluing in traditional processes. This transforms complex sequential processes into simple parallel assembly, significantly shortening the production cycle and greatly improving production efficiency. Second, since the skirt can be pre-formed as a whole, it avoids the cumulative errors caused by punching and feather insertion angles in traditional single-feather insertion processes. The molded clamping and fixing method ensures that each product has a high degree of concentricity and connection strength, resulting in a high yield rate and eliminating the need for extensive manual post-processing correction, thereby reducing production costs. Furthermore, the clamping structure of the separate head provided in this application, especially the preferred conical surface mating structure, provides a strong and uniform clamping force, ensuring the rigidity and strength of the connection between the skirt and the head, effectively improving the shuttlecock's flight stability and durability, and preventing the skirt from loosening or falling off.

[0039] A-Conical annular hole on the ball joint Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0041] Example 1

[0042] This embodiment provides a badminton shuttlecock with a split head and its manufacturing method. (Refer to...) Figure 1 The figure is a schematic diagram of the overall appearance of a badminton shuttlecock manufactured according to an embodiment of this application. Its structure mainly includes a shuttlecock head 1 and a skirt 2 fixed on the shuttlecock head 1.

[0043] The following is combined with Figures 1 to 4 The structure of this badminton shuttlecock is explained. Among other things, Figure 2This is a schematic diagram of the exploded structure of the badminton shuttlecock. Figure 3 This is a cross-sectional schematic diagram of the ball joint and the ball plug. Figure 4 This is a cross-sectional view of the assembled ball head. In this embodiment, the ball head 1 adopts a split structure, which includes a ball head seat 1.1 and a ball head plug 1.2. It can be understood that the ball head seat 1.1 constitutes the outer shell of the ball head, while the ball head plug 1.2 constitutes its inner core.

[0044] The overall shape of the shuttlecock head 1.1 is similar to that of a conventional badminton shuttlecock head. Its lower part is a hemispherical structure for hitting the shuttlecock, made of cork, wood chips, polymer synthetic materials, or a combination thereof, to provide good hitting feel and elasticity. Its upper part is formed as a roughly cylindrical base. It should be noted that the cylindrical base of the shuttlecock head 1.1 has a receiving cavity at its center for accommodating components. Specifically, this receiving cavity is a frustum-shaped hole A with an upper opening diameter larger than a lower opening diameter. The taper (i.e., half the taper angle) of the frustum-shaped hole A is precisely designed, for example, it can be set in the range of 20 to 25 degrees, and in this embodiment, it is specifically 22 degrees.

[0045] Accordingly, the ball plug 1.2 is a solid frustoconical plug, the shape, size, and taper of which are adapted to the frustoconical hole A. In other words, the outer surface of the ball plug 1.2 is formed into a conical surface that matches the inner wall of the frustoconical hole A. The material of the ball plug 1.2 may include, but is not limited to, foamed plastics (such as foamed polyethylene, polypropylene, polycarbonate, nylon, etc.) and composite materials of the above-mentioned polymer materials and cork chips, to ensure that it can withstand sufficient pressure without permanent deformation during the pressing process and can transmit effective clamping force.

[0046] The ball skirt 2 includes a ball skirt body 3 and a support part 4; the support part 4 is distributed on the ball skirt body 3 and serves a supporting function. The ball skirt body 3 is composed of a plurality of feathers or a ball skirt body formed as a whole; the support part 4 includes at least one support ring and / or a set of support rods 4.4; the support rods 4.4 are provided with insertion holes or slots for inserting the natural or artificial feathers; the support rings (4.1, 4.2, 4.3) are distributed on the support rods 4.4; the support rings are used to connect the plurality of natural or artificial feathers into a frustum shape.

[0047] In this embodiment, the ball skirt 2 is composed of multiple artificial feathers. (See reference...) Figure 3 and Figure 5The figure shows a schematic diagram of the structure of a single artificial feather. As shown, each artificial feather includes a shaft 3.1 as a framework and blades 3.2 integrally formed or fixed to both sides of the shaft 3.1. The shape, thickness, and flexibility of the blades 3.2 are aerodynamically optimized to simulate the flight characteristics of natural feathers. In this embodiment, the skirt 2 can specifically be composed of 16 artificial feathers, each with a total length of 76 mm, to meet the size requirements of a standard badminton shuttlecock.

[0048] This embodiment also provides a method for manufacturing a badminton shuttlecock, the process of which can be referred to. Figure 9 As shown, the method includes the following steps:

[0049] S10: Prefabricated trumpet-shaped skirt body or skirt. Unlike the traditional method of implanting individual feathers into the shuttlecock head, this step first pre-assembles all the feathers that make up the skirt into a complete, independent trumpet-shaped component. Specifically, the lower ends of the shafts 3.1 of 16 artificial feathers are gathered and positioned using a specialized fixture. This fixture has 16 positioning slots inside, and their distribution and tilt angles are precisely calculated to ensure that after the feathers are inserted, they naturally form a standard trumpet-shaped skirt with an opening diameter, deflection angle, and overall shape that meet the design requirements. In this way, the shape of all prefabricated skirts is highly consistent, thereby avoiding the cumulative errors caused by human operation and equipment precision factors in the traditional single-feather implantation process.

[0050] S20: Place the shuttlecock skirt, placing the skirt body or the lower end of the skirt into the receiving cavity of the outer shell, which forms part of the shuttlecock head. As a preferred fixing method, to further enhance the reliability and durability of the connection, adhesive can be applied before assembly. Specifically, a ring of high-strength structural adhesive, such as hot melt adhesive, epoxy resin adhesive, acrylic adhesive, or polyurethane adhesive, can be evenly coated on the inner wall of the frustum-shaped hole A of the shuttlecock head seat 1.1 using automatic dispensing equipment or manually. The adhesive layer thickness can be controlled at the "silk" level to ensure that the microscopic gaps between the mating surfaces are completely filled without affecting the final shuttlecock head weight and mating accuracy due to excessive adhesive. Then, the lower end of the pre-fabricated trumpet-shaped skirt in step S10, i.e., the gathered shaft bundle, is inserted from above into the frustum-shaped hole A coated with adhesive.

[0051] S30: Press-fitting and fixing: The core body is pressed into the receiving cavity, and the lower end of the skirt is clamped and fixed between the outer shell and the core body through the cooperation of the core body and the outer shell to form the ball head. The ball head plug 1.2, which is adapted to the frustum-shaped hole A, is aligned with the hole opening, and a stable and controlled axial pressure is applied to the ball head plug 1.2 using a pneumatic press, hydraulic press, or servo press, etc., to press it into the frustum-shaped hole A at a uniform speed. During the pressing process, since the outer conical surface of the ball head plug 1.2 and the inner conical surface of the frustum-shaped hole A have the same taper, they gradually come into contact, thereby applying a continuously increasing radial compressive force to the feather bundle of the skirt 2 located therebetween. It can be understood that this conical surface mating structure not only achieves automatic centering to ensure the concentricity of the skirt and the ball head, but also efficiently converts the axial pressing force into a strong and evenly distributed radial clamping force. The radial clamping force acts on each shuttlecock shaft, firmly pressing it against the inner wall of the frustoconical hole A. Simultaneously, the previously applied adhesive fills all the tiny gaps under pressure and forms a chemical bond after curing, thus achieving dual fixation through physical clamping and chemical bonding. The pressure device can be preset with a final pressure value or indentation depth as a stopping condition to ensure a high degree of consistency in the clamping force for each finished shuttlecock.

[0052] Once the adhesive has fully cured, the manufacturing of a sturdy and stable badminton shuttlecock is complete. Its final assembled state is shown in cross-section. Figure 4 As shown, the lower end of the ball skirt 2 is tightly clamped and fixed in the conical annular gap formed between the ball head seat 1.1 and the ball head plug 1.2.

[0053] Compared with existing technologies, the structure and method provided in this embodiment eliminate the need for traditional processes such as ball head drilling, single feather insertion, lining between shafts, and glue rolling. The production process can be simplified into two main modules: "prefabricated ball skirt" and "press assembly," making it suitable for automated production. This improves production efficiency, increases product consistency and yield, and reduces reliance on skilled workers and associated production costs.

[0054] Example 2

[0055] This embodiment illustrates that the technical solution of this application is also applicable to the manufacture of badminton shuttlecocks using natural feathers. In this embodiment, the structure of the shuttlecock head 1 is the same as that described in Embodiment 1, that is, it also adopts a split clamping structure consisting of a head seat 1.1 and a frustum-shaped head plug 1.2. The materials, shapes, and design of the frustum-shaped hole A of both are also consistent with those described in Embodiment 1.

[0056] The main difference between this embodiment and Embodiment 1 lies in the composition and prefabrication method of the ball skirt 2. The ball skirt 2 is composed of 16 selected and trimmed natural feathers (such as first- or second-grade goose or duck feathers).

[0057] Accordingly, step S10 (prefabricating the trumpet-shaped skirt) in its manufacturing method also adopts a method adapted to natural feathers. Specifically, this step can use a traditional hook-and-loop process to pre-connect the feathers into a whole. In operation, 16 natural feathers can be arranged on a special hook-and-loop fixture at specific intervals and angles, either inserted to the left or right. Then, high-strength nylon or cotton thread is used as a support ring, and it is interwoven at specific heights on the feather shaft (e.g., the upper and lower sections). Finally, by tightening the support ring, the 16 individual feathers are firmly woven together into a structurally stable and regularly shaped trumpet-shaped skirt. The prefabricated natural feather skirt can be transported and stored as an independent semi-finished product.

[0058] After the prefabrication of the shuttlecock skirt is completed, the subsequent assembly steps are basically the same as in Example 1. That is, in step S20 (placing the shuttlecock skirt), a thin and uniform layer of adhesive is applied to the inner wall of the frustum-shaped hole A of the shuttlecock head seat 1.1, and then the shaft bundle of the prefabricated natural feather shuttlecock skirt is placed into the frustum-shaped hole A as a whole. Next, in step S30 (pressing and fixing), a pressure device is used to press the shuttlecock head plug 1.2 into the frustum-shaped hole A. During the pressing process, the conical surfaces of the shuttlecock head plug 1.2 and the shuttlecock head seat 1.1 will also generate a strong and uniform radial clamping force on the shaft bundle of natural feathers. It can be understood that since the shuttlecock skirt has good overall rigidity due to the pre-weaving and shaping by the support ring, it is not easy to undergo disordered deformation when subjected to clamping force, which helps to ensure the regular shape of the final product shuttlecock skirt. The filling and curing effect of the adhesive further locks the position of all the shafts, ensuring the long-term reliability of the connection.

[0059] As can be seen from this embodiment, the core manufacturing concept of "prefabricating the shuttlecock skirt first, then clamping and fixing it as a whole" proposed in this application has broad applicability. When applied to the manufacture of natural badminton shuttlecocks, although the "threading" process is retained to ensure the shape of the skirt, the steps of "drilling holes on the shuttlecock head" and "single feather insertion" in the original process are replaced with the "overall pressing" step of this application. This method can also simplify the overall process flow, improve production efficiency and product concentricity and other quality indicators, while retaining the excellent flight performance brought by natural feathers. It has reference value for the technological upgrading and transformation of existing natural badminton shuttlecock production lines.

[0060] Example 3

[0061] This embodiment provides a more integrated badminton shuttlecock and its manufacturing method. In this embodiment, the shuttlecock head 1 still adopts a split conical clamping structure composed of a shuttlecock head seat 1.1 and a shuttlecock head plug 1.2. The improvement in its technical solution mainly lies in the structural design of the shuttlecock skirt 2.

[0062] Reference Figure 6The figure shows a partial structural diagram of a ball skirt with an integral support section used in this embodiment. In this embodiment, the ball skirt 2 includes multiple artificial feathers and an integral support section. The integral support section is a plastic component pre-molded in one piece by injection molding, and its material is usually a modified plastic with good rigidity and toughness, such as glass fiber reinforced nylon.

[0063] like Figure 6 As shown, the overall support structure may include at least two support rings staggered in height, such as an upper support ring 4.1 with a smaller diameter and a middle support ring 4.2 with a larger diameter. Between the support rings, 16 (or other numbers corresponding to the number of feathers) support rods 4.4 are integrally connected, evenly distributed circumferentially. The support rods 4.4, together with the support rings 4.1 and 4.2, form a stable, birdcage-like frustum-shaped frame structure. Each support rod 4.4 is provided with a structure for connecting to artificial feathers; for example, insertion holes (blind holes or through holes) or slots with one-sided openings may be provided at the top or side of each support rod 4.4 for inserting feather shafts 3.1.

[0064] Accordingly, the first step of the manufacturing method in this embodiment (step S10, prefabricating the skirt) also embodies a high degree of integration. This step specifically includes: first, injection molding the aforementioned integral support part; then, selecting short-shaft artificial feathers with adapted shaft lengths (for example, the shaft 3.1 is only 10-20 mm long), inserting the shafts 3.1 one by one into the insertion holes or slots on the support rods 4.4 of the integral support part, and fixing them by pre-filling glue into the insertion holes or by subsequent ultrasonic welding. Thus, a highly integrated skirt assembly composed of a plastic frame and artificial feathers is formed. The lower edge of this skirt assembly, that is, the end of the lowest support ring or support rod, is designed as a conical ring shape, the outer diameter and cone angle of which precisely match the frustum-shaped hole A in the ball head seat 1.1.

[0065] The subsequent assembly steps S20 and S30 are similar to those in Example 1. First, adhesive is applied into the frustoconical hole A of the ball head seat 1.1; then, the lower conical ring portion of the integrated ball skirt assembly is inserted into the frustoconical hole A; finally, the ball head plug 1.2 is pressed in, and the strong clamping force generated by the conical surface fit firmly clamps and fixes the lower part of the integrated ball skirt assembly between the ball head seat 1.1 and the ball head plug 1.2. In this structure, the ball head plug 1.2 not only clamps the lower conical ring of the support portion, but also applies pressure directly or indirectly to the inserted end of the shuttle shaft, thereby forming a double fixation to enhance the strength and reliability of the connection.

[0066] In addition, such as Figure 7As shown, the ball head and skirt can be fixed by a support portion. Specifically, the support portion includes support ring 4.1 (i.e., the first support ring), support ring 4.2 (i.e., the second support ring), and / or support ring 4.3 (i.e., the third support ring). Support rings 4.1 and 4.2 are distributed on the skirt body. Support ring 4.3 is connected to the lower end of the skirt body and is clamped and fixed between the outer shell and the inner core. The skirt body does not penetrate the support rod.

[0067] This embodiment replaces the "outlining" step with "injection molding" and "joining" processes by employing an injection-molded integral support component. Since all structural parameters of the skirt (such as feather spacing, deflection angle, and support ring position) are precisely defined by the mold, this facilitates a high degree of product consistency. The entire manufacturing process, from support component injection molding and feather insertion to final pressing assembly, is suitable for fully automated assembly line operations, thereby improving production efficiency and reducing manufacturing costs. Furthermore, this skirt structure with a rigid frame offers enhanced resistance to deformation and durability compared to traditional outlining skirts, providing more stable flight performance.

[0068] Example 4

[0069] This embodiment illustrates the application of the technical solution of this application in the field of integral injection molded plastic badminton shuttlecocks. Similar to the previous embodiments, the badminton shuttlecock in this embodiment also adopts a split shuttlecock head 1 composed of a shuttlecock head seat 1.1 and a shuttlecock head plug 1.2.

[0070] like Figure 8 As shown, the characteristic of this embodiment lies in the material and shape of the shuttlecock skirt 2. Specifically, the shuttlecock skirt 2 is no longer composed of multiple feathers, but is a component integrally formed in one piece through injection molding or molding processes. Its material can be a high-molecular foam material with specific elasticity and toughness, such as foamed polypropylene, foamed polyurethane, or other special modified plastics. By controlling the foaming ratio (e.g., between 1.2 and 6.0 times), the weight, stiffness, and aerodynamic properties of the skirt can be precisely adjusted to simulate the flight trajectory and hitting feel of a natural badminton shuttlecock. This integrally injection-molded skirt 2 has its lower part designed as a conical ring structure that matches the frustum-shaped hole A within the shuttlecock head seat 1.1. The outer surface of this conical ring has the same taper as the inner wall of the frustum-shaped hole A, and its dimensions are precisely calculated to ensure a tight fit during assembly.

[0071] The manufacturing process in this embodiment is correspondingly simplified. Step S10 (prefabricating the ball skirt) involves providing a pre-molded, integral plastic ball skirt. This ball skirt is a single, complete component, requiring no additional pre-assembly. Steps S20 (placing the ball skirt) and S30 (pressing and fixing) are consistent with the core concept of the aforementioned embodiment. During operation, adhesive can be applied to the inner wall of the frustum-shaped hole A in the ball head seat 1.1 to enhance the fixing effect. Then, the lower conical ring portion of the integral plastic ball skirt is placed into hole A. Finally, the ball head plug 1.2 is forcefully pressed in. Utilizing the large and uniform radial clamping force generated by the conical structure, the lower conical ring of the plastic ball skirt is firmly pressed and fixed between the ball head seat 1.1 and the ball head plug 1.2.

[0072] Compared with the planar bonding or slot connection methods commonly used in existing plastic badminton shuttlecocks, the conical clamping and fixing method adopted in this embodiment has the following technical advantages: Firstly, the contact area of ​​the conical surface is larger, which can more effectively disperse and transmit the impact force during the hit; secondly, the strong radial clamping force makes the bond between the skirt and the shuttlecock head more secure, effectively enhancing the connection strength, rigidity, and torsional resistance, helping to prevent the skirt from excessively deforming, loosening, or falling off under high-speed flight and strong impact. Therefore, this embodiment applies a split conical clamping structure to the integral injection-molded skirt, aiming to improve the problems of insufficient connection strength and poor durability of existing plastic badminton shuttlecocks, while maintaining its advantages in production cost and consistency, and improving the product's durability and flight performance stability.

[0073] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
