Description

Technical Field

[0001] This utility model relates to the field of golf ball technology, specifically to an improved golf ball. Background Technology

[0002] Golf, commonly known as the "little white ball," is a sport with a unique charm. It's an activity where people exercise, cultivate their minds, and improve their skills in a natural and elegant green environment. Playing golf involves using different golf clubs to hit a golf ball into a hole.

[0003] Based on their existing structure, golf balls can be broadly categorized into single-layer, double-layer, and multi-layered balls. Generally, the more layers a golf ball has, the farther it flies, the less prone it is to deformation, and the more expensive it is. Single-layered balls are typically used only as practice balls, double-layered balls are the most commonly used, while multi-layered golf balls are rarely used due to their high price.

[0004] Application publication number CN102294110A discloses a golf ball, specifically comprising a core layer, at least two intermediate layers sequentially surrounding the core layer, and a shell layer surrounding the intermediate layers; the shell layer has a thickness of 0.8–1.4 mm and a hardness (Shore D) of 40–50; the first intermediate layer closest to the shell layer has a thickness of 1.0–2.0 mm and a hardness (Shore D) of 50–65; the remaining intermediate layers immediately below the first intermediate layer have a thickness of 1.3–15 mm and a hardness (Shore D) of 30–70; the core layer has a radius of 5–18 mm and a hardness (Shore D) of 30–70; and the golf ball has a moment of inertia of less than 83 g·cm².

[0005] Therefore, the aforementioned golf ball is a multi-layered ball. However, its overall design still suffers from insufficient elasticity and speed upon impact. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide an improved golf ball, which increases the softness of the coating layer by setting multiple evenly distributed through holes on a coating layer, thereby improving its deformation effect. This can improve the elasticity and speed of the golf ball when it is hit, and also help to increase the initial velocity and flight distance of the golf ball.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] An improved golf ball includes a core layer, a first cover layer, and a second cover layer arranged sequentially from the inside out; an elastic overlay layer is further provided between the core layer and the first cover layer or between the first cover layer and the second cover layer; a plurality of evenly distributed perforations are provided on the overlay layer, penetrating both the inner and outer surfaces of the overlay layer; by providing a plurality of perforations on the overlay layer, the softness of the overlay layer can be increased, making it more deformable, thereby improving the elasticity and speed of the golf ball upon impact, and also helping to increase the initial velocity and flight distance of the golf ball.

[0009] Furthermore, when the covering layer is located between the core layer and the first cover layer, multiple protrusions protrude from the inner surface of the first cover layer and can be matched and inserted into the multiple perforations, and the inner surface of the first cover layer abuts against the outer surface of the covering layer; the arrangement of the protrusions helps to improve the connection stability between the covering layer and the first cover layer, so that the covering layer can stably feed back the elastic force to the first cover layer.

[0010] Furthermore, the protrusion passes through the perforation and connects to the surface of the core layer, making this structure more stable.

[0011] Furthermore, when the covering layer is located between the first covering layer and the second covering layer, multiple protrusions protrude from the inner surface of the second covering layer and can be matched and inserted into the multiple perforations, and the inner surface of the second covering layer abuts against the inner surface of the covering layer; the arrangement of the protrusions helps to improve the connection stability between the covering layer and the second covering layer, so that the covering layer can stably feed back the elastic force to the second covering layer.

[0012] Furthermore, the protrusion passes through the perforation and connects to the outer surface of the first covering layer, making this structure relatively stable.

[0013] Furthermore, both the perforation and the protrusion are cylindrical.

[0014] Furthermore, the coating layer is made of an ionomer resin.

[0015] Furthermore, the core layer is made of high-elasticity rubber; the first cover layer is made of high-elasticity ionomer; and the second cover layer is made of polyurethane.

[0016] Furthermore, the thickness of the coating layer is less than the thickness of the first covering layer and the second covering layer, respectively.

[0017] Furthermore, the pit is hemispherical in shape.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention increases the softness of the coating layer by setting multiple evenly distributed perforations on the coating layer, thereby improving its deformation effect and enhancing the elasticity and speed of the golf ball. It also helps to increase the initial velocity and flight distance of the golf ball.

[0020] In addition, by setting protrusions on the inner surface of the coating layer that can be inserted into the perforations, not only can the stability of the structure be guaranteed, but also the elasticity can be stably fed back to the outer layer, allowing the golf ball to have better elasticity and speed.

[0030] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model. Example 1:

[0031] like Figures 1-4As shown, an improved golf ball includes a core layer 1, a first cover layer 2, and a second cover layer 3 arranged sequentially from the inside out. An elastic overlay layer 4 is further disposed between the core layer 1 and the first cover layer 2, or between the first cover layer 2 and the second cover layer 3. Multiple evenly distributed perforations 5 are provided on the overlay layer 4, penetrating both its inner and outer surfaces. Therefore, the second cover layer 3 serves as a shell layer.

[0032] Therefore, by setting multiple evenly distributed perforations 5 on the covering layer 4, this utility model can increase the softness of the covering layer 4, making it more deformable. This can improve the elasticity and speed of the golf ball when it is hit, and also help to increase the initial velocity and flight distance of the golf ball.

[0033] In this embodiment, the covering layer 4 is disposed between the core layer 1 and the first covering layer 2, so that the covering layer 4 can support the first covering layer 2 while also facilitating the outward transmission of elasticity.

[0034] In this embodiment, the coating layer 4 is made of ionomer resin. Since ionomer resin with a certain degree of elasticity is an existing material, it will not be described in detail here.

[0035] Preferably, the core layer 1 is made of high-elasticity rubber; the first cover layer 2 is made of high-elasticity ionomer; and the second cover layer 3 is made of polyurethane. Since the high-elasticity rubber, high-elasticity ionomer, and polyurethane mentioned above are all prior art, they will not be described in detail here. However, those skilled in the art should know that other existing materials can also be used for the core layer 1, the first cover layer 2, and the second cover layer 3; specific examples will not be given here.

[0036] like Figure 3 As shown, in this embodiment, the thickness of the covering layer 4 is less than the thickness of the first covering layer 2 and the second covering layer 3, respectively. The thickness of the covering layer 4 can be set according to actual needs, such as being appropriately thickened or thinned. However, it should be noted that the thickness of the covering layer 4 should not be too thick or too thin, so as not to affect the performance of the covering layer 4.

[0037] like Figure 1 As shown, a plurality of evenly distributed pits 7 are provided on the outer surface of the second covering layer 3.

[0038] like Figure 1 As shown, in this embodiment, the shape of the pit 7 is set to hemispherical. Alternatively, the shape of the pit 7 can also be elliptical, square, or polygonal, etc. In specific implementations, the number of pits 7 can be in the range of 80-120. Example 2:

[0039] like Figure 5 As shown, the difference between this embodiment and the first embodiment is that in this embodiment, the covering layer 4 is disposed between the first covering layer 2 and the second covering layer 3, so that the covering layer 4 can support the second covering layer 3 while also transmitting the elastic force outward. Example 3:

[0040] like Figure 6 As shown, the difference between this embodiment and the first embodiment is that in this embodiment, when the covering layer 4 is located between the core layer 1 and the first covering layer 2, that is, when the first covering layer 2 and the second covering layer 3 are not covered by the covering layer 4, multiple protruding posts 6 protrude from the inner surface of the first covering layer 2 and can be matched and inserted into multiple through holes 5, and the inner surface of the first covering layer 2 abuts against the outer surface of the covering layer 4.

[0041] Therefore, the use of the protruding post 6 helps to improve the connection stability between the covering layer 4 and the first covering layer 2, so that the covering layer 4 can stably feed the elastic force back to the first covering layer 2, and allow the golf ball to have better elasticity and speed.

[0042] In addition, to ensure stability, each protrusion 6 is connected to the surface of the core layer 1 after passing through the perforation 5. This structure is not only stable, but also can effectively transmit the elastic force of the core layer 1 outward.

[0043] Preferably, the perforation 5 and the protrusion 6 can both be cylindrical. Of course, their shapes can also be set to other shapes if necessary. Example 4:

[0044] like Figure 7 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 3 is that, in this embodiment, when the covering layer 4 is located between the first covering layer 2 and the second covering layer 3, that is, there is no covering layer 4 between the core layer 1 and the first covering layer 2; multiple protruding posts 6 protrude from the inner surface of the second covering layer 3 and can be matched and inserted into multiple perforations 5, and the inner surface of the second covering layer 3 abuts against the inner surface of the covering layer 4.

[0045] Similarly, the use of the protruding post 6 also helps to improve the connection stability between the covering layer 4 and the second cover layer 3, so that the covering layer 4 can stably feed the elasticity back to the second cover layer 3, and allow the golf ball to have better elasticity and speed.

[0046] To ensure stability, each protrusion 6 is also connected to the outer surface of the first covering layer 2 after passing through the perforation 5. This structure is stable and can better transmit the elastic force outward.

[0047] More specifically, in this embodiment, the second cover layer 3 is fitted onto the cover layer 4 by injection molding, thereby ensuring a stable connection between the second cover layer 3 and the cover layer 4.

[0048] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
