Description

Golf club head including carbon fiber blade

The present invention relates to a golf club head, and more particularly to a golf club head comprising a carbon fiber striking face plate.

In order to improve the hitting performance of wood-type golf club heads, the current research and development direction is mainly to change the weight configuration of the club head and adjust the center of gravity of the club head by changing the material and reducing the weight of the structure, so as to optimize the moment of inertia (MOI) of the golf club head when hitting the ball, and improve the flight distance and flight direction stability of the golf ball after being hit.

Among many known wood-type golf club heads, some of them are made of heterogeneous materials, such as a carbon fiber material-formed component combined with a metal material-formed component. For example, the club head is divided into a club head body, a ball striking panel, and a top cover, and a weight component is installed in the club head body. Some of the components in the club head body, the ball striking panel, and the top cover are made of metal materials, and the remaining components are made of carbon fiber materials. Generally speaking, common wood-type golf club heads use a carbon fiber material at the front end of the club head body combined with a metal material for striking the ball, or a metal material at the front end of the club head body combined with a carbon fiber material for striking the ball.

In the known golf club head products related to the above-mentioned heterogeneous material bonding, when a combination structure is selected in which a metal club head body front end is bonded to a carbon fiber striking component, a panel assembly hole is first pre-formed at the front end of the club head body, and then a plate-shaped striking panel is embedded in the panel assembly hole of the club head body.

The existing club head structure in which the front end of the metal club head body is combined with the carbon fiber striking component can reduce weight by selecting lightweight carbon fiber materials, but the carbon fiber striking panel accounts for a small proportion of the overall weight of the club head, and the effect of transferring the weight reduction to the weight configuration of the club head is limited.

Furthermore, in the assembly structure in which the striking face plate is embedded in the front end of the club body, the face plate assembly hole at the front end of the club body and the plate-shaped striking face plate are only flatly bonded, and the bonding strength between the two is insufficient. When hitting the ball, the bonding part between the striking face plate and the club body is prone to cracking due to excessive impact shear force, and even the striking face plate falls off, so it is necessary to further improve the structure.

The purpose of the present invention is to provide a golf club head including a carbon fiber hitting panel, so as to solve the problems that the conventional golf club head has a limited effect of reducing weight and transferring the weight of the club head in the combination structure of the carbon fiber hitting panel combined with the front end of the metal club head body, and the hitting panel part is easily detached due to excessive impact shear force in the combination structure of the front end of the club head body being adhered and fixed to the hitting panel part.

In order to achieve the above-mentioned purpose, the golf club head including a carbon fiber striking faceplate proposed by the present invention comprises: A hollow club head body, which includes a club head base made of metal material, the front end of the club head base has a panel fixing frame, and a club sleeve installation portion extending upward from one side of the panel fixing frame, a panel mounting opening is formed in the panel fixing frame, and a panel bearing wall is located at the inner side periphery of the panel mounting opening, and a fitting recess with an opening facing forward is provided in the panel bearing wall; and A carbon fiber hitting panel is fixed in the panel fixing frame of the base of the club head. The carbon fiber hitting panel includes a hitting panel part and a fitting protrusion arranged on the periphery of the back of the hitting panel part. The hitting panel part is matched and fitted in the panel assembly opening of the panel fixing frame to form a hitting surface. The panel bearing wall is fixed to support the hitting panel part, and the fitting protrusion is embedded in the matching fitting concave part in the panel bearing wall.

The overall structure of the golf club head has at least the following advantages: 1. Optimized bonding strength and hitting performance: The golf club head of the present invention mainly has a carbon fiber hitting panel fixed in the panel fixing frame at the front end of the hollow club head body. The carbon fiber hitting panel includes a hitting panel part and a fitting protrusion extending backward from the inner side periphery of the hitting panel part. The panel fixing frame at the front end of the club head body is provided with a panel assembly opening matching the hitting panel part. The panel bearing wall on the inner side of the panel assembly opening forms a fitting concave opening facing forward. The carbon fiber hitting panel The board is combined by matching the striking panel part with the panel assembly port of the club head body, the panel bearing wall is located at the periphery of the back of the striking panel part of the carbon fiber striking panel to provide fixation and bearing, and the engaging convex part is matched with the engaging concave part of the panel bearing wall on the inner side of the panel assembly port, so that it can effectively optimize the bonding strength and striking performance between each other, and avoid the existing carbon fiber striking panel of the golf club head from easily falling off due to excessive impact shear force. 2. Increase the weight margin of the golf club head: Based on the above, the golf club head of the present invention is based on a club head body at least partially made of metal. In addition to reducing weight by setting a carbon fiber hitting panel, the amount of metal material used in the club head body is reduced by setting a fitting recess in the panel bearing wall in the panel fixing frame at the front end of the club head body. In addition, the fitting protrusion of the carbon fiber hitting panel on the back of the hitting panel part fills the solid space of the fitting recess, so that the golf club head can maintain sufficient bonding strength between the club head body and the carbon fiber hitting panel, and has the function of further reducing weight, thereby increasing the weight margin of the golf club head.

The golf club head of the present invention can further include a top cover and a bottom plate disposed on the top of the metal club head body in a hollow club head body, and at least a portion of the top cover and the bottom plate can be made of carbon fiber material or high molecular polymer material, so that the club head body can be reduced in weight by using the top cover or the bottom plate of the carbon fiber material or high molecular polymer material while maintaining its proper strength, thereby changing the weight configuration of the club head and adjusting the center of gravity of the club head, thereby optimizing the moment of inertia (MOI) of the golf club head when hitting the ball.
