Description

Technical Field

[0001] This utility model relates to the technical field of artificial feathers and badminton shuttlecock products. Background Technology

[0002] Traditional badminton shuttlecocks are made from natural feathers, mainly using the limited natural scalpel feathers from poultry. Most natural feathers are made from goose or duck feathers that have been bleached and screened. The collection process is difficult, the consistency is poor, and the processing is complicated and time-consuming. As a result, natural feathers have a high damage rate, poor stability, and insufficient durability in badminton. In recent years, there have also been problems such as the shortage of badminton shuttlecocks and their high prices.

[0003] Nylon shuttlecocks were introduced decades ago, with feathers primarily made of nylon plastic. Their performance was far inferior to that of shuttlecocks made of natural feathers, especially in terms of overall flight performance. They were difficult to match the performance of natural shuttlecocks. Furthermore, although nylon shuttlecocks have undergone several product design iterations since their introduction, there have been few major breakthroughs, making them difficult for users to accept and failing to meet the performance requirements of badminton competitions. Therefore, they cannot replace natural shuttlecocks and cannot solve or improve the problems mentioned above associated with natural shuttlecocks.

[0004] In view of this, the inventors of this case conducted in-depth research and improvement on the problems existing in the products, and carried out trial production tests, which led to the creation of this case. Summary of the Invention

[0005] The purpose of this invention is to provide a durable artificial badminton shuttlecock made of composite materials, which can achieve the performance required for competition, in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the technical solution of this utility model is: a durable composite material artificial badminton shuttlecock, comprising a shuttlecock head, a feather shaft connected to the shuttlecock head, and feather pieces connected to the feather shaft; the feather shaft is a composite layer structure comprising carbon fiber, glass fiber, and thermoplastic material fused and hot-pressed, and / or the feather pieces are a sheet structure comprising a polyester resin film and a modified high molecular weight polyethylene film bonded together. Furthermore, the wool sheet is provided with a perforated structure.

[0007] Furthermore, the holes in the hole structure are circular, polygonal, or elliptical, and the diameter of the hole or the diameter of the inscribed circle of the hole ranges from 0.5 to 1.5 mm. Furthermore, the diameter of the hole structure ranges from 0.6 to 1 mm.

[0008] Furthermore, the hair bar has a multi-layered composite structure from the inside out, including a carbon fiber core layer, a glass fiber intermediate layer outside the carbon fiber core layer, and a thermoplastic material outer layer outside the glass fiber intermediate layer.

[0009] Furthermore, the thickness of the carbon fiber core layer is greater than that of the glass fiber intermediate layer, and the thickness of the glass fiber intermediate layer is greater than that of the thermoplastic material outer layer.

[0010] Furthermore, the thickness ratio of the carbon fiber core layer, the glass fiber intermediate layer, and the thermoplastic material outer layer is 5:3:2.

[0011] Furthermore, the thickness of the bob ranges from 0.3 to 0.6 millimeters.

[0012] Furthermore, one end of the hair rod is a ball-head connecting end connected to a ball head, and the other end is a hair-piece connecting end for connecting with the hair piece. The hair rod has a structure in which the width gradually decreases from the ball-head connecting end to the hair-piece connecting end.

[0013] Furthermore, the side of the feather, which is a polyester resin film, faces the outside when it is made into an artificial shuttlecock.

[0014] Furthermore, the thickness ratio of the polyester resin film to the modified polyethylene film is 2:3. Furthermore, the thickness of the fleece film ranges from 0.4 to 0.8 mm.

[0015] Furthermore, the thickness of the feathers ranges from 0.5 to 0.6 millimeters. By adopting the above technical solution, the beneficial effects of this utility model are: the main improvement of the above-mentioned artificial badminton shuttlecock compared to the prior art lies in the novel material application and structural combination of the feathers and shaft. This improvement enables the stability of the shuttlecock's trajectory and flight performance when hit to be closer to that of a natural badminton shuttlecock made from natural feathers, effectively solving the problem of poor performance of previous nylon plastic artificial badminton shuttlecocks, thus achieving the effect of replacing natural badminton shuttlecocks.

[0016] The improved shaft structure of the aforementioned artificial badminton shuttlecock is composed of a combination of multiple materials forming a multi-layered composite structure. Carbon fiber boasts the highest strength and rigidity modulus among currently available materials; glass fiber exhibits high toughness and fatigue resistance; thermoplastic materials offer high impact resistance; and the shuttlecock itself is composed of a thin sheet structure formed by bonding polyester resin film and modified polyethylene film. This sheet structure, achieved through physical modification and chemical optimization, is an ultra-lightweight and highly flexible sheet structure, meeting the required performance. In summary, the artificial badminton shuttlecock of this invention simulates and rivals the performance of shuttlecocks made from natural feathers, achieving the performance requirements for competition. Furthermore, it significantly surpasses the lifespan of natural shuttlecocks, exhibiting excellent durability. Therefore, it can replace natural shuttlecocks for professional competition use, thus achieving the aforementioned objectives of this invention.

[0023] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0024] This embodiment discloses a durable composite material artificial badminton shuttlecock, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a ball head 1, several hair rods 2, and several hair pieces 3. One end of each hair rod 2 is a ball head connecting end inserted into the ball head 1, and the other end is a hair piece connecting end. The hair pieces 3 are connected to the hair piece connecting ends one-to-one. The number of hair rods 2 and hair pieces 3 and the connection and arrangement structure between them and the ball head 1 can be set according to relevant standard requirements. For example, following the specific shape of the hair pieces 3 and hair rods 2, they can be inserted into the ball head 1 in sequence at a certain deflection angle, and set through a trumpet-shaped ball skirt composed of two sets of support coils. Of course, it is not limited to this. It can be improved according to product needs to obtain products with different advantages or even better products.

[0025] The main improvement of this utility model lies in the hair rod 2 and the hair piece 3. Therefore, the ball head 1 will not be described in more detail here. It can adopt existing material structure or new ball head components.

[0026] The shuttlecock 2 of this invention is made of a composite of multiple fiber materials. By combining the composition and structural characteristics of different fiber materials and scientifically proportioning the mixture, its performance parameters are precisely tuned to achieve the support and durability required for badminton hitting. This overcomes the shortcomings of traditional nylon plastic materials in terms of strength and rigidity modulus, and surpasses shuttlecocks made of single fiber materials in terms of toughness, fatigue, and impact resistance, resulting in better performance and a longer service life. Specifically, this embodiment mainly uses carbon fiber, glass fiber, and thermoplastic materials, which are fused and hot-pressed using a precision resin system to form the composite structure of the shuttlecock 2. The carbon fiber material possesses the highest strength and rigidity modulus among existing known materials; the glass fiber material exhibits high toughness and fatigue resistance; and the thermoplastic material possesses high impact resistance. Therefore, using these materials can achieve and improve the performance required for badminton in multiple aspects. Furthermore, the composite structure here is not simply a combination of different materials, but rather a composite structure with specific structural characteristics. For example, it can be a layered structure based on the material properties. This embodiment discloses a preferred structural configuration, such as... Figure 3 As shown, the bristle 2 is a multi-layered composite structure from the inside out, including a carbon fiber central layer 21, a glass fiber intermediate layer 22 outside the carbon fiber central layer 21, and a thermoplastic material outer layer 23 outside the glass fiber intermediate layer 22. The aforementioned layered structure places the carbon fiber material, which has the highest strength and highest rigidity modulus, at the center to meet the basic strength requirements. The glass fiber material and thermoplastic material, through their properties, provide corresponding performance to the bristle and also protect the inner layers, thereby improving the performance of the bristle 2 in multiple ways. Further preferably, the thickness of the carbon fiber central layer 21 can be greater than the thickness of the glass fiber intermediate layer 22, and the thickness of the glass fiber intermediate layer 22 can be greater than the thickness of the thermoplastic material outer layer, such as... Figure 3 As shown, the overall thickness is preferably between 0.3 and 0.6 mm. In the trial production test of this embodiment, a badminton shuttlecock sample with a thickness within the aforementioned range and a layer thickness ratio of 5:3:2 for the carbon fiber central layer, glass fiber intermediate layer and thermoplastic material outer layer was selected. The sample obtained better test values ​​in the product test.

[0027] Based on the aforementioned proportions, during manufacturing, the mechanical interlocking can be further strengthened through thermoforming coupling and bridging in a resin system, as well as the micro-anchoring structure of the surface treatment. This enhances the beneficial effects of combining different material components and structural characteristics with a scientifically balanced mixture. The resulting artificial shuttlecock can achieve the performance parameters required for badminton shuttlecock striking, including shaft support and durability. Furthermore, the shaft 2 can be further designed with a width that gradually decreases from the head connection end to the feather connection end (here, width refers to the distance between opposite sides of the shaft 2). This structural design allows for adjustments to the weight distribution, more closely mimicking the weight distribution of a natural badminton shuttlecock shaft. This results in an artificial shuttlecock whose trajectory stability and flight performance are more closely similar to those of a shuttlecock made from natural feathers.

[0028] Another improvement of this utility model lies in the feather piece 3. This improvement can be applied based on the above-mentioned feather shaft 2 structure, or it can be applied to existing artificial shuttlecocks or improved artificial shuttlecocks. In this embodiment, the feather piece 3 is as follows: Figure 4 As shown, the structure comprises a sheet composed of a polyester resin film 32 and a modified high-molecular-weight polyethylene film 33 bonded together. During production, the material undergoes physical modification and chemical optimization to synthesize lightweight and flexible feathers, thus meeting the performance requirements for badminton shuttlecock striking. The feather 3 has the polyester resin film 32 facing outwards in the artificial shuttlecock configuration, while the modified high-molecular-weight polyethylene film 33 faces inwards. This structure enhances the wear resistance and other properties of the feather 3 through the polyester resin film 32, thereby improving the durability of the artificial shuttlecock. According to standards, the thickness of all feathers can range from 0.4 to 0.8 mm, preferably 0.5 to 0.6 mm, to better simulate the shape of natural feathers in the feather area and their performance during shuttlecock use. The shape of the feather 3 can also be designed in other shapes, such as square, round, or elliptical, to closely approximate the performance of different shuttlecocks made from different types of natural feathers. Other performance requirements are not limited to the aforementioned thickness.

[0029] In this embodiment, the feather 3 is provided with a hole structure 31. The hole structure 31 can realize the aerodynamic performance required for the flight of the badminton shuttlecock, which is beneficial to greatly improve the flight speed and flight path stability, without affecting its use and durability. The holes in the hole structure can be circular, polygonal, elliptical, etc. The preferred arrangement structure disclosed in this embodiment, as shown in the figure, is a circular hole arranged on the feather 3. This is a reasonable distribution according to the required performance requirements, and its diameter ranges from 0.5 to 1.5 mm (other non-circular holes can be their inscribed circle diameter). In the production test, the badminton shuttlecock sample made of feather 3 with a diameter range of 0.6 to 1 mm obtained better test values ​​in the wind tunnel test (the rotation speed is uniform, between 400 and 500 rpm) and the actual flight performance test (hit by a ball machine, the ball speed is between 75 and 77, and the flight path is centered). It shows excellent and close to the ball path of a natural badminton shuttlecock, which makes the ball path stability and flight performance when hit more closely resemble those of a badminton shuttlecock made of natural feathers. The other performance characteristics of the aforementioned technical solution sample, as demonstrated in actual application test data, also indicate that the artificial badminton shuttlecock of this invention possesses excellent durability. It boasts a longer lifespan than ordinary natural badminton shuttlecocks (actual player tests show usage time is more than twice as long), and achieves flight performance and characteristics approaching those of conventional natural badminton shuttlecocks, including flight stability during sports use. This meets the compliance and fairness requirements of professional badminton competitions. This invention utilizes a combination of multiple materials and structural optimization to create complementary and optimized interactions, resulting in superior performance compared to single materials and thus excellent durability.

[0030] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
