Description

Technical Field

[0001] The utility model relates to the field of golf balls, in particular to an improved structure of a golf ball concave hole. Background Art

[0002] A golf ball has many dimples on its surface. When the golf ball is hit, the dimples interfere with the air flow around the golf ball, resulting in chaotic airflow separation and "turbulence". Turbulence can promote the displacement between the separation point on the upper side of the golf ball and the separation point on the lower side. This displacement is generated by the swirl, which can enhance the lifting force acting on the golf ball. Better dimples can effectively interfere with the air flow and produce a longer flight path. Many existing golf balls have dimples on their surface that are covered by a combination of different sizes. The dimples and gaps are of different sizes, resulting in complex structures and low production efficiency.

[0003] Therefore, it is necessary to provide a golf ball structure to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Moreover, the terms "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0025] Please refer to Figure 1-6 As shown, a golf ball structure includes a ball surface 1, on which a plurality of concave holes 2 are arranged, the concave holes 2 have the same size, are arranged in a ring-shaped manner on the longitude and latitude of the ball surface 1, and evenly cover the ball surface 1. In this way, under the condition of the same size of the concave holes 2, the ball surface 1 can basically achieve even coverage of the sphere surface through reasonable distribution, and at the same time, the gap area of ​​the concave holes 2 is small, and the size of the gap is also relatively uniform. The size of the concave holes 2 on the ball surface 1 is uniform, so that the overall outer surface of the golf ball is beautiful and simple.

[0026] Based on the above technical solution, it also includes pole concave holes 21 set at the upper and lower poles of the ball surface 1, that is, a pole concave hole 21 is distributed at each of the two poles of the ball surface 1 and the rotation axis of the golf ball passes through the center of the pole concave hole 21.

[0027] Furthermore, the concave holes 2 distributed on any meridian of the spherical surface 1 form a starting column 22. Starting from the starting column 22, the number of concave holes 2 on each meridian is the same. The starting column 22 includes the extreme concave holes 21, that is, the starting column 22 includes two upper and lower extreme concave holes. At the same time, the angle 3 of the central axes of two adjacent concave holes 2 along the meridian of the spherical surface 1 is the same.

[0028] Specifically, the angle 3 is preferably set to 11.25°.

[0029] On this basis, the distribution of the concave holes 2 in the latitude direction can be optionally calculated by the following formula, and rounded to an even number according to the actual distribution:

[0030] Wherein, N is the number of concave holes 2 distributed on the latitude, D is the diameter of the golf ball (42.67 mm), d is the diameter of the concave hole 2, n is the nth latitude (ranging from 0 to 7), and θ is the interval angle 4 of the concave holes 2 distributed on the latitude.

[0031] In a preferred embodiment, the golf ball has a diameter of 42.67 mm.

[0032] In a preferred embodiment, the concave hole 2 is a Φ4mm arc concave hole, the hole depth (the distance from the lowest point of the ball surface 1) is 0.25mm, the total number of holes is 322, and the center of the concave hole 2 is at the outer end of the ball surface 1. It can be understood that Figure 6 The concave hole 2 is formed by partially cutting a sphere with a diameter of 4 mm into the surface 1 of the golf ball.

[0033] Correspondingly, the concave holes 2 are distributed at an interval angle 4 of 11.25° on the latitude line. Figure 1 The distribution of concave holes 2 from the pole to the equator is 1 (polar concave hole 21), 6, 12, 18, 22, 26, 30, 30, 32 (equatorial hole arrangement).

[0034] In order to achieve the purpose of covering the surface of the sphere by replicating a group of concave holes 2, the preferred sphere surface 1 includes a concave hole domain 5 composed of multiple concave holes 2, and the concave hole domain 5 can be replicated in a symmetrical, rotational, mirrored or other manner to achieve covering the sphere surface 1.

[0035] For the same purpose, the optional minimum group of the concave hole domain 5 is the "1 / 8" structure, and the "1 / 8" structure can be constructed as a whole through symmetrical replication, which means that the "1 / 8 structure" is the minimum group of the present application, and can cover the golf ball body through symmetrical replication, and it can be replicated to construct the ball surface 1 so that the concave holes 2 cover the ball surface 1.

[0036] The golf ball structure provided by the present application brings at least the following beneficial effects:

[0037] 1. The present application unifies the size of the concave holes on the surface of the ball and reasonably distributes the concave holes on the surface of the ball. The concave hole domain can achieve uniform coverage of the surface of the sphere through symmetry, rotation, mirroring, etc. Not only is the gap area small, but the size of the gap is also relatively uniform. At the same time, the outer surface is beautiful and simple, which can better enhance the user experience.

[0038] 2. After the diameter of the sphere of the present application is determined, the angle of uniform distribution of the concave holes at the meridians can be determined by selecting the appropriate concave hole size, and at the same time, a concave hole is distributed at each of the two poles. In addition, the distribution of the concave holes in the latitude direction can be calculated by a formula according to the actual distribution situation, and rounded to an even number. The structure is simple and can greatly improve production efficiency.

[0039] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
