Description

Technical Field

[0001] This invention belongs to the field of badminton production technology, specifically relating to a badminton feather protector. Background Technology

[0002] Currently, mainstream badminton shuttlecock manufacturing processes generally employ the traditional assembly process of 'feather insertion—stringing—adhesion.' For example, the traditional coil used to wrap the feathers is wound approximately 10 millimeters above the shuttlecock's head plane in the first turn, and the second turn is wound 20 millimeters away from the head plane. However, this process suffers from significant technical bottlenecks: manual or semi-automated operation easily leads to uneven feather spacing, coil tension imbalance, and insufficient adhesive curing reliability, which severely weakens the shuttlecock's flight stability and consistency. Therefore, developing a convenient insertable badminton feather guard that integrates simplified structure, efficient assembly, and high operational stability is crucial. Summary of the Invention

[0003] To solve at least one of the above-mentioned technical problems, the present invention provides a badminton feather protector, including a base, a top, and a conical connecting frame connecting the base and the top;

[0004] The base is provided with bottom holes for fixing the base of the feathers of the badminton shuttlecock; The top is provided with a top hole in the middle of the feather for fixing the badminton shuttlecock, and the top hole corresponds to the bottom hole one by one; The tapered connecting frame includes multiple radial bars arranged in a tapered shape. One end of each radial bar is connected to the outer edge of the base, and the other end is connected to the inner edge of the top to increase the strength of the connection.

[0005] After the feather pieces are inserted into the top and bottom holes, the straight line of the diameter bar intersects with the straight line of the feather pieces.

[0006] The diameter of the top hole is larger than the outer diameter of the feather, so that there is a gap between the feather and the top hole.

[0007] The base has a mounting part, which is cylindrical, and the outer wall of the mounting part has annularly distributed holes. The mounting part has a buckle structure for connecting the head of a badminton shuttlecock; the diameter of the mounting part is 12-20mm and the length is 5-15mm, preferably, the diameter of the mounting part is 18mm and the length is 9mm.

[0008] The snap-fit ​​structure includes protrusions on the outer wall of the mounting part. These protrusions are either continuously arranged annular rings or spaced-apart dots, corresponding to the number of top and bottom holes. A mounting groove is formed on the ball head, and the protrusions fit into the mounting groove to achieve snap-fit ​​installation, simplifying the installation process and reducing installation time. The protrusions and mounting grooves are snap-fitted together, and glue can be added during installation to further strengthen the fixation.

[0009] The number of diameter bars is 3-18; the length of the diameter bars is 15-30mm; the inclination angle α of the diameter bars (301) is (90°, 105°). Preferably, there are 6 diameter bars, each with a length of 25mm; the inclination angle α of the diameter bars is 92°.

[0010] Compared to traditional structures, this invention provides stronger support for the feathers when the shuttlecock is subjected to a high-speed smash, making the feathers less prone to deformation or breakage.

[0011] The number of bottom holes and top holes is set to 12-18; the diameter of the bottom holes and top holes is 2-4mm. Preferably, the number of bottom holes and top holes is set to 15; the diameter of the bottom holes is 3.1mm and the diameter of the top holes is 3.4mm.

[0012] The badminton feather protector is injection molded from nylon material in one piece, which facilitates integrated production. This results in a modular design with high precision. The consistent spacing between the bottom holes and the top holes ensures uniform spacing between the feathers, guaranteeing the stability of the shuttlecock during flight.

[0013] With the above technical solution, the size of the bottom hole and the top hole are adapted to the cross-section of the feather piece. By inserting the bottom hole and the top hole, the feather piece can be positioned and fixed, realizing tool-free assembly.

[0014] The base has a placement area for installing smart chips.

[0015] Compared with the prior art, the advantages of the present invention are: the present invention has a simple structure, which can make the spacing between the feathers uniform and eliminates the need for coil winding, thus achieving the effect of feather protection. The badminton shuttlecock produced by the present invention is suitable for various indoor and outdoor venues, and is especially suitable for temporary competitions or training.

[0017] To enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection claimed by the present invention, the present invention will be described in detail below with reference to certain specific embodiments. It should be noted that the following are merely some specific embodiments of the inventive concept, and the specific and direct descriptions of related structures are only for the purpose of facilitating understanding of the present invention; the specific features do not necessarily or directly limit the scope of the present invention.

[0018] Referring to the accompanying drawings, the present invention adopts the following technical solution: a badminton shuttlecock feather protector, comprising a base 1, a top 2, and a conical connecting frame 3 connecting the base 1 and the top 2; The base 1 is provided with a bottom hole 101 for fixing the base of the feather 5 of the badminton shuttlecock; The top 2 is provided with a top hole 201 in the middle of the feather piece 5 for fixing the badminton shuttlecock, and the top hole 201 corresponds one-to-one with the bottom hole 101; The tapered connecting frame 3 includes multiple tapered strips 301. One end of each strip 301 is connected to the outer edge 102 of the base 1, and the other end is connected to the inner edge 202 of the top 2, so as to increase the strength of the connection.

[0019] After the feather pieces are inserted into the top hole 201 and the bottom hole 101, the straight line of the diameter bar 301 intersects with the straight line of the feather piece 5, and the included angle between them is 6°-10°, preferably 8°. It is because of this included angle that the diameter bar 301 can effectively "hold" the feather piece 5, forming a triangular support structure in mechanical terms, thereby dispersing the impact force.

[0020] The diameter of the top hole is larger than the outer diameter of the feather piece, so that there is a gap between the feather piece 5 and the top hole.

[0021] The number of bottom holes and top holes is set to 12-18; the diameter of bottom hole 101 and top hole 201 is 2-4mm. Preferably, the number of bottom holes and top holes is set to 15; the diameter of bottom hole 101 is 3.1mm and the diameter of top hole 201 is 3.4mm.

[0022] At the moment of impact, the shuttlecock is subjected to the combined effects of air resistance and the impact force of the racket. The feathers of the shuttlecock tend to spread outward. Traditional shuttlecocks use rigid connections or tight perforation structures, which exert a greater restraining force on the feather blades 5. This rigid restraint cannot effectively buffer the impact at the moment of impact, causing the impact force to act directly on the vulnerable part of the feather blades 5 (i.e., the second coil of the traditional coil), which can easily cause feather breakage.

[0023] This invention introduces the concept of a (flexible structure) through structural design, specifically: the top hole 201 is enlarged, i.e., there is a gap, which opens up the rigid constraint of the feather 5. When the hitting force is transmitted, the loose design of the top hole 201 allows the feather to make a slight movement, i.e., it can be slightly stretched, so that the force can be smoothly transmitted to the root of the durable feather 5 and the head of the shuttlecock. At this time, the top hole 201 does not create a constraint, avoiding the concentration of force at the top. When the deformation is transmitted to the top and is constrained, the remaining force is greatly reduced due to the dissipation of energy along the path, reducing the probability that the feather 5 is easy to break at this point.

[0024] The gap design avoids stress concentration that could lead to instantaneous breakage. This design significantly increases the shuttlecock's durability compared to traditional rigid connections, maintaining flight stability while mitigating the destructive force of powerful smashes.

[0025] During the flight of the shuttlecock, aerodynamics causes the feather 5 to naturally retract, and the top hole 201 at the top acts as a constraint, keeping the feather 5 within the range of the top hole 201 and ensuring flight stability. Since the diameter of the top hole 201 is slightly larger than the outer diameter of the feather 5, the difficulty of inserting the feather 5 is reduced, and production efficiency is also improved.

[0026] This invention achieves a transformation from a traditional rigid connection to a flexible connection by enlarging the top hole. This "expanding then retracting" mechanism of the feathers cleverly utilizes the dynamic characteristics of badminton shuttlecock feathers. During impact, the unfolding of the feathers guides the impact force to a more robust part, distributing it through the diameter bar 301 to the base 1 and the shuttlecock head 4. The overall frame structure of the shuttlecock feather protector distributes the stress, rather than concentrating it at the base of the feathers, reducing the risk of feather breakage. During flight, the constraint of the top hole ensures the shuttlecock feathers 5 maintain perfect roundness, monitoring durability and flight stability. In production, increasing the diameter of the top hole reduces the difficulty of inserting the feathers 5, improving production efficiency.

[0027] The base 1 has a mounting part 103, which is cylindrical, and its outer wall has annularly distributed holes 104. The mounting part 103 has a snap-fit ​​structure for connecting the shuttlecock head 4. The diameter of the mounting part 103 is 12-20 mm, and its length is 5-15 mm; preferably, the diameter is 18 mm and the length is 9 mm.

[0028] The snap-fit ​​structure includes protrusions 105 on the outer wall of the mounting part. The protrusions 105 are either continuously arranged annular or spaced-apart bumps, corresponding to the number of top and bottom holes. A mounting groove 401 is formed on the ball head, and the protrusions 105 fit into the mounting groove to achieve snap-fit ​​installation, simplifying the installation process and reducing installation time. The protrusions 105 and the mounting groove 401 are snap-fitted together, and glue can be added during installation to strengthen the fixation.

[0029] The number of diameter bars 301 is 3-18; the length of diameter bars 301 is 15-30mm; the inclination angle α of diameter bars 301 is (90°, 105°). Preferably, there are 6 diameter bars, each 25mm long; the inclination angle α of the diameter bars is 92°. This invention reconstructs the force transmission path of a badminton shuttlecock when it is impacted through a unique 92° inclination design. This angle is not arbitrarily set, but is the optimal solution obtained based on structural mechanics testing—it allows the impact force during a smash to be dispersed along the inclined surface of the connecting frame to the overall structure. Instead of being concentrated at the base of feather 5, the staggered support acts like a "mechanical buffer slope" for the feather. Compared to the traditional 100-degree structure, this staggered support significantly reduces the breakage rate of feathers, essentially equipping each feather with a dedicated "breakage-resistant support".

[0030] With the mounting groove 401 of the shuttlecock head 4 as the plane, after the feather 5 is installed through the top hole 201 and the bottom hole 101, the tilt angle of the feather 5 is between 95 and 105°. Since the diameter of the top hole 201 is slightly larger than the outer diameter of the feather, the feather has the freedom to finely adjust its angle when subjected to flight forces, thus forming dynamic aerodynamic adaptability. In traditional feather support frames, the diameter bars are set parallel to the line where the feather is located. Compared with the traditional structure, the feather support frame of this invention provides stronger support for the feather 5 when the shuttlecock is subjected to high-speed smashes, making the feather 5 less prone to deformation or breakage.

[0031] In this invention, the diameter bar is 25mm long, which is 5mm higher than the traditional coil winding. The top hole evenly divides the spacing of the feather pieces 5, so that the vulnerable parts of the feather pieces 5 directly exposed to the racket impact area are wrapped and raised by the badminton feather guard of this invention, reducing the direct impact area and thus improving the durability of the badminton. Compared with the traditional first coil, the root area of ​​the feather pieces is smoother, reducing airflow obstruction and improving the flight stability of the badminton in windy conditions. In addition, this application omits the traditional first coil, directly reducing the weight in this area, reserving valuable weight and space for the later implantation of smart chips, and balancing the global center of gravity without sacrificing the weight of the shuttlecock head.

[0032] The badminton feather protector is injection molded from nylon material in one piece, which facilitates integrated production. This results in a modular design with high precision. The consistent spacing between the bottom holes 101 and the consistent spacing between the top holes 201 ensures that the distance between the feathers 5 is consistent, thus guaranteeing the stability of the badminton shuttlecock during flight.

[0033] Nylon material possesses properties similar to "elastic skeletons," exhibiting strong resistance to bending and capable of withstanding thousands of cycles of deformation without fatigue fracture. This allows the feather guard to possess both the rigidity to support the feathers and the toughness to absorb impact, becoming a "strong and resilient link" connecting the shuttlecock head and the feathers. This invention utilizes nylon injection molding, a material with a higher elongation at break than ordinary nylon, enabling it to adapt to the slight arc deformation during impact.

[0034] Through the above technical solution, the size of the bottom hole 101 and the top hole 201 is adapted to the cross-section of the feather piece 5, that is, the inner wall of the bottom hole 101 and the top hole 201 can abut against the outer wall of the feather piece 5 to achieve clamping. By inserting the bottom hole 101 and the top hole 201, the feather piece 5 can be positioned and fixed, realizing tool-free assembly.

[0035] The base features a placement area for installing smart chips. The hollow structure and standardized design of the badminton feather guard provide physical space for future integration of micro-sensors. For example, an accelerometer can be integrated inside the feather guard to monitor smash speed and trajectory in real time; or an RFID chip can be embedded in the snap mechanism to record the number of times the shuttlecock has been used and its performance degradation data. This "structural pre-planning + modular design" approach not only addresses the current durability issue but also provides a technical interface for the intelligent upgrading of badminton, offering future scalability.

[0036] Compared with the prior art, the advantages of the present invention are: the present invention has a simple structure, which can make the spacing between the feather pieces 5 consistent, and does not require coil winding, thus achieving the effect of protecting the feathers. The badminton shuttlecock produced by the present invention is suitable for various indoor and outdoor venues, and is especially suitable for temporary competitions or training.

[0037] To increase the stability after installation, glue can be applied between the base of feather 5 and the shuttlecock head 4, and between the base of feather 5 and the shuttlecock guard. An appropriate amount of glue is used for auxiliary fixation, forming a connection system that combines rigidity and flexibility. The glue does not create a rigid lock, but rather, while maintaining gaps and providing a cushioning function, it prevents feathers from falling off during high-frequency vibrations, acting like an "anti-loosening insurance" for the flexible connection. This process enhances the synergy between the guard, the shuttlecock head, and the feather shaft, significantly improving the overall structural stability and achieving a new balance between durability and flight stability in the shuttlecock.

[0038] After the feather 5 is inserted into the top and bottom holes, the extension direction of the rib 301 is no longer parallel to the central axis of the feather 5, but rather forms a certain angle, creating a cross arrangement. This cross arrangement naturally forms multiple triangular force-bearing units among the rib 301, the feather 5, the top hole 201, and the bottom hole 101.

[0039] In the overall structure of a badminton shuttlecock, these triangular support structures effectively disperse the stress generated during flight and impact, enhancing the overall stability and resistance to deformation. Compared to traditional parallel support methods, the cross-bracing enhances lateral stiffness and reduces the swaying amplitude of the feathers during high-speed rotation or impact, thus maintaining consistent flight posture. Simultaneously, the triangular structure possesses excellent mechanical transmission characteristics, quickly transferring localized forces to the entire feather guard, preventing stress concentration-induced localized damage and extending the shuttlecock's lifespan.

[0040] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
