Description

Technical Field

[0001] This utility model relates to a shuttlecock head structure, and more particularly to a gradient perforated shuttlecock head structure for artificial badminton shuttlecocks. This structure is a shuttlecock head design using a perforation process, used to improve the fixing and shaping effect of the feathers of artificial badminton shuttlecocks. It belongs to the field of sporting goods technology. Background Technology

[0002] Traditional badminton shuttlecock heads are typically fixed with natural or artificial feathers using a drilling process. This involves drilling round or square holes in the shuttlecock head surface, inserting the feathers, and securing them with glue. However, this process has several drawbacks: (1) the drilling process easily generates burrs and debris, which can obstruct the insertion of the feathers; (2) after fixing, the feathers are prone to shifting left and right, especially during high-speed hits, affecting the shuttlecock's flight stability and durability. In addition, among existing artificial badminton shuttlecock perforation processes, one patent uses a fully flat hole design (i.e., flat from the entrance to the depth). While this design can initially compress the feathers, the flat entrance makes initial piercing difficult, resulting in low processing efficiency, and insufficient deep fixation, causing the feathers to loosen easily.

[0003] Therefore, it is particularly necessary to provide a shuttlecock head structure with a reasonable structural design that improves the shaping effect after the feather blades are inserted, prevents lateral displacement, and enhances the overall durability and flight performance of the shuttlecock. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned deficiencies in the existing technology and provide a gradient perforated head structure for artificial badminton shuttlecocks. Through the gradient shape design of the perforations, the shaping effect after the feathers are inserted is improved, lateral displacement is prevented, and the overall durability and flight performance of the shuttlecock are enhanced.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: the gradient perforated shuttlecock head structure for artificial badminton includes a shuttlecock head body, the surface of which is provided with multiple perforations, all of which are gradually arranged along the axial depth direction of the shuttlecock head. The multiple perforations are characterized by: each of the multiple perforations including an inlet end, a middle transition section, and a deepest end; the inlet end is a circular hole with a diameter of 0.5mm to 2mm, used for initial piercing of the feathers; the middle transition section is a flat hole with a width of 1.5 to 3 times the diameter of the inlet end and a thickness of 0.5 to 1 times the diameter of the inlet end, used for squeezing and fixing the feathers; the deepest end is a knife-shaped opening with an opening width smaller than the width of the flat hole, forming a serrated or blade-like structure, used to lock the end of the feathers and prevent displacement.

[0006] Preferably, the plurality of puncture holes described in this invention are evenly distributed on the semi-circular surface of the ball head, with a quantity of 6 to 16, arranged radially, and the depth of the puncture holes is 20% to 80% of the radius of the ball head.

[0007] Preferably, the material of the ball head body of this invention is cork, fiberglass, plastic, foam, or composite material, with a smooth puncture hole wall and an inlet end radius of 0.1mm to 0.5mm to reduce puncture resistance.

[0008] Preferably, the blade-shaped opening of this invention has a cutting edge angle of 30° to 60° and an opening length of 0.5mm to 1.5mm, forming single-sided or double-sided serrations to enhance the shaping effect of the hair.

[0009] Preferably, the ball head body of this invention is a hemispherical or near-hemispherical structure.

[0010] Preferably, the gradient design of the punch hole in this invention is formed by a mold punching process; it avoids the burr problem of traditional drilling process and the positioning (left and right displacement) problem of artificial badminton shuttlecock blade, and avoids the existing technology of full flat hole punching structure.

[0011] Compared with the prior art, this utility model has the following advantages and effects: (1) The overall structure is reasonably designed, and multiple punch holes are provided on the surface of the ball head body. The multiple punch holes are gradually set along the axial depth direction of the ball head; (2) The punching process replaces drilling, avoids burrs, and improves production efficiency by more than 20%; (3) The gradual structure increases the fixing force of the feather by 30%, making it less prone to displacement. The number of hits is increased by 50% after testing; (4) It is suitable for artificial feather materials (such as nylon or synthetic fibers) and is compatible with existing badminton production lines.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] Example

[0022] See Figures 1 to 7 This embodiment of the gradient perforated shuttlecock head structure for artificial badminton includes a head body 1, which is hemispherical or nearly hemispherical in shape. Multiple perforations 2 are provided on the surface of the head, with a gradient design along the axial depth direction of the head. This gradient design differs from existing fully flat hole processes (where the inlet is flat and prone to jamming). The round inlet hole ensures smooth insertion, while the deep, pointed hole enhances locking and avoids the risk of infringement. The number and distribution of the perforations 2 are optimized through a radial arrangement to evenly distribute stress.

[0023] In this embodiment, each puncture hole 2 is divided into three regions along the depth direction: the puncture hole 2 includes an inlet end 21, a middle transition section 22, and a deepest end 23; the inlet end 21 is a circular hole with a diameter of 0.5mm to 2mm, which facilitates the initial puncture of the hair tip and reduces resistance.

[0024] In this embodiment, the intermediate transition 22 is a flat hole with a width of 1.5 to 3 times the diameter of the inlet end 21 and a thickness of 0.5 to 1 times the diameter of the inlet end 21; the flat shape compresses the side of the blade to provide initial fixing force and prevent rotational displacement.

[0025] In this embodiment, the deepest end 23 is a knife-shaped opening with a width smaller than that of a flat hole, forming a serrated or blade-like structure. The knife-shaped opening and the blade lock the end of the blade, forming a serrated latch to prevent displacement and ensure long-term shaping.

[0026] In this embodiment, multiple puncture holes 2 are evenly distributed on the semi-circular surface of the ball head, with a quantity of 6 to 16, arranged radially, and the depth of the puncture holes 2 is 20% to 80% of the radius of the ball head.

[0027] In this embodiment, the main body of the ball head is made of cork, fiberglass, plastic, foam, or composite material. The wall of the puncture hole 2 is smooth, and the radius of the rounded corner of the inlet end 21 is 0.1mm to 0.5mm to reduce puncture resistance.

[0028] In this embodiment, the blade angle of the dagger-shaped opening is 30° to 60°, and the opening length is 0.5mm to 1.5mm, forming single-sided or double-sided serrations to enhance the shaping effect of the hair leaves.

[0029] Example 1: The ball head has a diameter of 26mm and is made of hemispherical material. Sixteen puncture holes (2) are distributed equidistantly around the circumference of the ball head. Each puncture hole (2) has a circular inlet (area a) with a diameter of 1.8mm and a depth of 2mm; a flat inlet in the middle section (area b) with a width of 2mm, a thickness of 0.45mm, and a length of 6mm; and a pointed opening at the deep end (area c) with a cutting edge angle of 45° and a length of 1mm. The total depth of each puncture hole (2) is 9mm.

[0030] Production process: A special mold punching machine is used for one-time molding; the artificial blade (carbon fiber composite material) is inserted into the round hole entrance and locked to the deep end with a sharp blade, and a small amount of glue is used to help fix it; Test results: the blade displacement rate is <5%, which is better than the 15% of traditional drilling.

[0031] Example 2: Similar to Embodiment 1, but with 16 perforations, an inlet diameter of 1.5mm, a flat hole width of 2mm, and serrated edges on both sides of the pointed opening. Suitable for badminton shuttlecocks used in high-speed competitions, providing stronger fixation.

[0032] The ball head structure of this utility model is not limited to the above embodiments. Various variations are possible as long as the above-mentioned implementation effects are achieved.

[0033] This embodiment describes a gradient perforated head structure for artificial badminton shuttlecocks. Through a combination of a round hole at the entrance, a flat hole in the middle transition section 22, and a sharp opening at the deepest end 23, the gradient design of the perforation 2 is formed using a mold-perforation process, avoiding the burr problems of traditional drilling processes. This achieves smooth insertion, compression shaping, and end locking of the feathers, significantly improving stability while avoiding the limitations of existing fully flat perforated structures. This structure is suitable for the production of artificial badminton shuttlecocks, with a simple process and low cost.

[0034] Based on the above description, those skilled in the art are already able to implement it.

[0035] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model.
