Description

Composite golf club heads

The present invention relates to a golf club head, in particular to a composite golf club head.

Among the many known wood-type golf club heads, some of them are made of heterogeneous materials, such as carbon fiber parts and metal parts. Generally speaking, common wood-type golf club heads are made of carbon fiber parts and metal parts, or metal parts and carbon fiber parts.

Among the known golf club head products related to the bonding of heterogeneous materials, a combination structure of a carbon fiber club head body and a metal striking component at the front end is selected, which has the characteristics of lightweight carbon fiber material to reduce weight and metal striking components to provide a crisp hitting sound.

However, in the combination structure of the carbon fiber material club head body and the metal material striking component, when the carbon fiber material is pre-formed into the club head body, a panel assembly hole is formed at the front end of the club head body, and the pre-formed plate-shaped striking panel is adhered to the panel assembly hole at the front end of the club head body. Since the striking panel and the club head body are only a flat bonding structure, and the two are fixed with adhesive such as structural adhesive, the bonding strength between the two is limited. When the club head hits the ball, the shear force during the impact is large, which can easily cause the bonding part between the striking panel and the club head body to crack, or even the striking panel to fall off. For this, it is necessary to further improve the structure.

The purpose of the present invention is to provide a composite golf club head to solve the technical problem of poor bonding strength of the existing golf club head with heterogeneous bonding of the striking face plate.

In order to achieve the above-mentioned purpose, the composite golf club head proposed by the present invention comprises: a club head body formed by composite material molding; and a heterogeneous composite ball striking component, which is fixed to the front end of the club head body and includes a ball striking face plate formed by metal material, and a component base formed on the outer periphery of the ball striking face plate by placing the pre-formed ball striking face plate in a mold and combining the composite material with a hot press, wherein the component base forms a club connecting portion on one side of the ball striking face plate, wherein, The striking panel includes a panel body and a fitting edge protruding outward from the periphery of the panel body along the direction of the board surface. The striking panel defines a striking area and an outer ring area located outside the striking area. The component base includes a panel fitting portion and an extension portion extending backward from the periphery of the panel fitting portion. The fitting edge is embedded in the panel fitting portion of the component base. The fitting edge is tightly covered by the panel fitting portion, and the rear end of the extension portion is fixedly connected to the front end of the club head body.

The structure of the composite golf club head mentioned above not only reduces weight and increases weight margin by using the composite molding of the club head body and the composite component base formed integrally with the heterogeneous composite striking component on the outer periphery of the striking panel, but also provides a crisp hitting sound by using the metal striking panel. In addition, the metal striking panel is formed integrally with the composite component base in the mold to produce a close bonding effect between the heterogeneous materials of the two, thereby enhancing the stability of the heterogeneous bonding.

The composite golf club head of the present invention can further utilize the panel interlocking portion of the component base to form a bearing ring and a hollow area located in the bearing ring. The bearing ring is attached to the back of the outer ring area of the striking panel to provide good back support performance. The hollow area corresponds to the striking area, so that the heterogeneous composite striking component has good striking performance.

The composite golf club head of the present invention can further form a closed filling space in the club head tail at the rear end of the club head body, and fill the filling space with a plastic weight body of high specific gravity material. The non-solid property of the plastic weight body that can change shape, and the spatial configuration and setting of the filling space in the club head body, can facilitate the weight configuration of the club head body, and the plastic weight body is encapsulated in the club head body.
