Please refer to FIG. 3 to FIG. 5 , which are respectively a perspective view and a cross-sectional view of a top view angle and a lower view angle of a preferred embodiment of the golf club head according to the present invention. view. The golf club head 1 of the present invention primarily includes a ball head body 10, at least one upper recess 20, and at least a lower recess 30.

As shown in FIG. 3 and FIG. 4, the ball head body 10 may be a member integrally molded from a metal material (for example, titanium or titanium alloy), and the ball head body 10 of the present invention is a golf club head. However, it can also be other types of club heads, such as irons or putters. The ball head body 10 has a striking panel 11, a crown 12 and a sole 13 for striking a golf ball. In one embodiment, the striking panel 11, the crown portion 12 and the bottom portion 13 are integrally joined to each other to form the ball head body 10.

As shown in FIG. 3 and FIG. 4, the at least one upper groove 20 is disposed on the surface of the crown portion 12, and the opening width thereof may be, for example, 12 mm (but not limited thereto), and the upper groove 20 is opposite. The striking panel 11 is closer to the center of the crown 12. In this embodiment, an upper groove 20 is disposed on the surface of the crown portion 12 as an example, but the number is not limited thereto. The upper groove 20 extends in parallel with the striking panel 11 , and at least one upper rib 21 is disposed in the upper recess 20 . In this embodiment, the at least one upper rib 21 may be, for example, a sheet having a thickness of about 2 mm, the sheet extending direction is perpendicular to the striking panel, and the upper recess 20 is divided into two or more sub-parts. Groove. In this embodiment, the upper groove 20 is provided with a plurality of the upper ribs 21 at an average interval, and the spacing between the adjacent two upper ribs 21 may be, for example, 18 mm. Furthermore, the opening of the upper recess 20 tapers into the ball head body 10 such that each of the upper ribs 21 is substantially inverted triangle.

As shown in FIGS. 4 and 5, the at least lower recess 30 is provided on the surface of the bottom portion 13, and the opening width thereof may be, for example, 12 mm (but not limited thereto), and The lower recess 30 is closer to the striking panel 11 with respect to the center of the bottom portion 13. In this embodiment, the lower groove 30 is provided on the surface of the bottom portion 13 as an example, but the number is not limited thereto. The structure of the lower recess 30 is similar to that of the upper recess 20, and extends in a direction parallel to the striking panel 11, and at least the lower rib 31 is disposed in the lower recess 30. In this embodiment, the at least one lower rib 31 is a one-piece body, and the sheet extending direction is perpendicular to the striking panel, and the lower recess 30 is divided into two or more sub-grooves. In this embodiment, the lower grooves 30 are provided with a plurality of the lower ribs 31 at an average interval, and the spacing between the adjacent two lower ribs 31 may be, for example, 18 mm.
