Description

Technical Field

[0001] The present invention relates to a golf club head, and in particular to a golf club head comprising a carbon fiber ball striking component. Background Art

[0002] For the club head structure of a wood club in a golf club, it is usually achieved by changing the material combination and reducing the weight of the structure, and adjusting the center of gravity of the club head by changing the weight configuration of the club head, thereby increasing the moment of inertia (MOI) of the golf club when hitting the ball, thereby achieving the purpose of improving the flight distance and flight direction stability of the golf ball after being hit.

[0003] Among the various wood club head structures currently known, the composition structure of some club heads is a heterogeneous material combination of a component formed of a carbon fiber material and a component formed of a metal material. Among the many existing club head products with a combination of heterogeneous materials, a combination structure of a club head body made of a metal material and a striking component made of a carbon fiber material is selected, wherein a fitting portion at the rear end of the striking component is sleeved on the front end of the club head body and bonded and fixed; or an opening is set at the front end of the club head body, and a plate-shaped striking panel is embedded and bonded in the opening.

[0004] Although both can reduce weight by selecting lightweight carbon fiber materials as the striking components, the front end of the club head body forms a flange with a full perimeter, and the striking component extends backwards on the back of the striking panel portion to form a fitting portion close to the full perimeter, and the fitting portion is sleeved outside the flange at the front end of the club head body. The full perimeter relative fitting combination structure has limited weight reduction effect on the club head itself. As for another form of the combined structure in which the striking panel is embedded in the front end opening of the club head body, due to the small area of ​​the contact between the perimeter of the striking panel and the edge of the opening hole, the striking panel is easily detached due to excessive impact shear force when hitting the ball. For the above problems of the existing golf club heads, it is necessary to further improve the structure. Summary of the invention
