Description

Technical Field

[0001] This utility model belongs to the technical field of sporting goods, specifically relating to a new type of high-hardness artificial badminton shuttlecock. Background Technology

[0002] Badminton is a sport with a long history, originally made of natural feathers and cork. With the development of technology, modern artificial shuttlecocks made of synthetic materials such as nylon have emerged and are gradually being used in amateur and professional competitions.

[0003] Current synthetic shuttlecocks lack effective cushioning and protective rings and nano-coatings, making them prone to cracking at the connection between the shuttlecock head and the skirt due to impacts. The surface becomes slippery, affecting shot control. Furthermore, they are not wear-resistant and are prone to bacterial growth, thus shortening their lifespan and affecting the gaming experience. Utility Model Content

[0004] The purpose of this invention is to provide a new type of high-hardness artificial badminton shuttlecock, aiming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel high-hardness artificial badminton shuttlecock includes a head assembly and a skirt assembly connected to the head assembly. The head assembly is provided with a composite fiber reinforced keel structure, a high-elasticity cushioning foam layer, a deformation energy-absorbing composite layer, a waterproof and breathable protective membrane layer, and a wear-resistant woven outer layer from the inside out.

[0007] As a preferred embodiment of this utility model, an elastic buffer protective ring is provided at the connection between the ball skirt assembly and the ball head assembly.

[0008] As a preferred embodiment of this utility model, the composite fiber reinforced keel structure is a columnar structure and is arranged along the axial direction of the ball head assembly.

[0009] As a preferred embodiment of this utility model, the high-elasticity cushioning foam layer is wrapped and disposed on the outer surface of the composite fiber reinforced keel structure.

[0010] As a preferred embodiment of this utility model, the deformation energy-absorbing composite layer is coated and disposed on the outer surface of the highly elastic cushioning foam layer.

[0011] In a preferred embodiment of this utility model, the waterproof and breathable protective membrane layer is disposed on the outer surface of the deformation energy-absorbing composite layer, and the wear-resistant woven outer layer is disposed on the outer surface of the waterproof and breathable protective membrane layer.

[0012] As a preferred embodiment of this utility model, the elastic buffer protective ring is a ring structure, and the outer side of the elastic buffer protective ring is evenly distributed with feathers in a ring shape, and the outer side of the feathers is fitted with a tenon.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: the chemical bonding and mechanical interlocking of the elastic buffer protective ring and the shuttlecock assembly effectively improve the crack resistance of the connection part, completely solving the problem of collision cracking. The micro-anchored composite structure formed by the wear-resistant woven outer layer and the waterproof and breathable protective membrane layer increases the surface friction coefficient, thereby avoiding slippage. At the same time, the antibacterial coating effectively reduces the bacterial growth rate. The nano-composite feather blades adopt a hydrophobic nano-coating combined with the axial support of the reinforced keel structure, which improves the overall wear resistance by four times while ensuring the accuracy of hitting control, extending the service life of the shuttlecock, and significantly improving the hitting stability and hygiene performance.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example

[0024] Reference Figures 1-4 This is an embodiment of the present invention, which provides a novel high-hardness artificial badminton shuttlecock, including a shuttlecock head assembly 1 and a shuttlecock skirt assembly 2 connected to the shuttlecock head assembly 1. The shuttlecock head assembly 1 is provided with a composite fiber reinforced keel structure 11, a high-elasticity cushioning foam layer 12, a deformation energy-absorbing composite layer 13, a waterproof and breathable protective membrane layer 14, and a wear-resistant woven outer layer 15 from the inside to the outside.

[0025] The design incorporates a multi-layered composite structure in the head assembly 1 and skirt assembly 2, using a specially formulated hot melt adhesive for interlayer bonding. This adhesive exhibits excellent permeability at high temperatures, allowing it to penetrate deep into the micropores of each material to form chemical bonds. Combined with the mechanical locking structure between the composite fiber reinforced keel structure 11 and the high-elasticity cushioning foam layer 12, the connection strength and overall integrity between the functional layers are significantly improved, enabling the shuttlecock to maintain structural stability even under severe impact. Furthermore, by coating the outer surface of the high-elasticity cushioning foam layer 12 with a tough OPP film, the overall toughness and strength of the material are significantly enhanced. This OPP film layer not only improves the tear resistance of the high-elasticity cushioning foam layer 12 but also effectively prevents structural damage to the high-elasticity cushioning foam layer 12 under repeated impacts.

[0026] Specifically, an elastic buffer protective ring 21 is provided at the connection between the ball skirt assembly 2 and the ball head assembly 1.

[0027] Among them, the elastic buffer protective ring 21 set at the connection between the skirt assembly 2 and the head assembly 1 adopts a ring-shaped reinforced structure. Its inner side is chemically bonded to the head assembly 1 by hot melt adhesive, while its outer side is mechanically interlocked with the support coil, forming a double fixing mechanism. This not only provides excellent impact buffering performance, but also effectively avoids the problem of loosening of the connection parts due to long-term use, greatly improving the structural reliability of the badminton shuttlecock.

[0028] Furthermore, the composite fiber reinforced keel structure 11 is a columnar structure, arranged along the axial direction of the ball head assembly 1.

[0029] Among them, the composite fiber reinforced keel structure 11 adopts an axial columnar design, and its surface is provided with regularly arranged positioning grooves, which form a precise fit with the raised structure on the inner surface of the high elastic buffer foam layer 12. The combination of mechanical interlocking structure and hot melt adhesive penetration fixation significantly improves the bonding strength between the composite fiber reinforced keel structure 11 and the high elastic buffer foam layer 12, ensuring that there will be no interlayer separation when hitting the ball at high speed.

[0030] Preferably, the high-elasticity cushioning foam layer 12 is wrapped around the outer surface of the composite fiber reinforced keel structure 11, and the deformation energy-absorbing composite layer 13 is wrapped around the outer surface of the high-elasticity cushioning foam layer 12.

[0031] Among them, the high-elasticity cushioning foam layer 12 adopts a special open-cell structure, which not only ensures the connection strength with the composite fiber reinforced keel structure 11, but also forms a continuous energy transfer path with the deformation energy-absorbing composite layer 13, so that the impact energy can be gradually dissipated along a specific direction, avoiding local damage caused by stress concentration, and greatly improving the impact resistance and service life of the badminton shuttlecock.

[0032] The deformation-absorbing composite layer 13 adopts a gradient material design. Its inner layer is bonded to the high-elasticity cushioning foam layer 12 through hot melt adhesive at the molecular level, while the outer layer is interlocked with the waterproof and breathable protective membrane layer 14 through micro-mechanical interlocking. This ensures the effective transfer of stress between the functional layers, enabling the shuttlecock to maintain overall deformation coordination when impacted, and avoiding damage caused by local stress concentration.

[0033] It should be noted that the waterproof and breathable protective membrane layer 14 is applied to the outer surface of the deformation energy-absorbing composite layer 13, and the wear-resistant woven outer layer 15 is applied to the outer surface of the waterproof and breathable protective membrane layer 14.

[0034] Among them, the waterproof and breathable protective membrane layer 14 and the wear-resistant woven outer layer 15 adopt a special composite processing technology to form a micro-concave-convex structure on the surface of the membrane layer, which forms a mechanical anchoring effect with the fibers of the woven layer, ensuring excellent waterproof performance. It also significantly improves the interlayer bonding strength by increasing the interface bonding area, so that the badminton shuttlecock can maintain stable performance in a humid environment.

[0035] Furthermore, the elastic buffer protective ring 21 has a ring structure, and the outer side of the elastic buffer protective ring 21 is evenly distributed with pinnae 22 in a ring shape.

[0036] Among them, the elastic buffer protective ring 21 is made of highly elastic polyurethane material, and its inner side is provided with a dovetail groove structure that cooperates with the head component 1, which greatly improves the reliability of feather fixation and the overall rigidity of the skirt, effectively solving the problem of feathers easily falling off in traditional artificial badminton shuttlecocks.

[0037] It should be noted that a systematic optimization has been carried out for the structure of 13-16 shuttlecocks, upgrading the traditional three support coils to five high-strength aluminum alloy coils, increasing the yield strength by 80%. Combined with the herringbone serrated root structure of the composite fiber reinforced keel structure 11, the overall rigidity of the shuttlecock skirt is improved. The innovative nested connection structure forms a mechanical interlock between the special sleeve and the herringbone serrations of the feather shaft, and is then radially tightened by a high-strength elastic rubber ring, which improves the reliability of the feather connection by 120% compared to the traditional structure. This composite connection system can reduce the feather loss rate under a 30m / s impact to below 0.5%, with a feather thickness of 0.5-0.8mm, while maintaining a torsional stiffness of 85N·m / rad, perfectly solving the structural strength and flight stability problems of multi-strand shuttlecocks.

[0038] When the shuttlecock is hit, the impact force is first transmitted to the deformation energy-absorbing composite layer 13 through the wear-resistant woven outer layer 15 and the waterproof and breathable protective membrane layer 14. This layer absorbs the initial impact energy through gradient deformation. Subsequently, the stress is evenly dispersed through the open structure of the high-elasticity buffer foam layer 12 and directionally transmitted along the axial columnar design of the composite fiber reinforced keel structure 11. At the same time, the elastic buffer protective ring 21 of the shuttlecock skirt assembly 2 alleviates the stress concentration at the connection point through the annular double-fixed structure, so that the impact energy is absorbed and dispersed by the multi-layer structure. Throughout the process, the molecular bonding and mechanical locking structure formed by the special hot melt adhesive ensure that each functional layer remains stably connected, while the optimized nanocomposite feather 22 maintains the stability of the flight attitude through precise aerodynamic design, ultimately achieving efficient dissipation of impact energy and precise control of the flight trajectory.

[0039] In summary, by using the mechanical locking mechanism between the composite fiber reinforced keel structure 11 and the high-elasticity cushioning foam layer 12, combined with the molecular-level penetration bonding of special hot melt adhesive, a super-strong bond is achieved between the functional layers of the shuttlecock assembly 1. The elastic cushioning protective ring 21 adopts a ring-shaped double-fixed design, with the inner side chemically bonded to the shuttlecock assembly 1 and the outer side mechanically interlocked with the support coil, which improves the connection reliability of the shuttlecock skirt assembly 2 by more than 200%. The optimized nano-composite feathers 22, combined with the aerodynamic shape design, improve flight stability by 35%. At the same time, the micro-anchoring structure of the wear-resistant woven outer layer 15 and the waterproof and breathable protective membrane layer 14 extends the product's service life by 3 times in humid environments. This solves the core problems of separation between layers, connection failure, and feather loss in traditional artificial badminton shuttlecocks, achieving a simultaneous breakthrough in hitting feel, flight performance, and durability.
