Golf club head

Abstract

A golf club head includes a head body having an opening and a connection portion around the opening; and a cup face including a main board having a bending portion toward the head body on at least one edge of the main board, wherein a joint surface is formed on an edge of the bending portion to be combined with the connection portion of the head body; and a board structure stacked with the main board, wherein the material of the board structure is different from the material of the main board, and an explosion welding layer is formed between the board structure and the main board. Because of the design of the bending portion of the cup face, the welded areas of the cup face and head body are far away from the explosion welding layer to prevent the separation of the board structure and the main board.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a golf club head, and more especially, to the golf club head with a composite plate.[0003]2. Background of the Related Art[0004]In general, the golf club head 10, as shown in FIG. 1, includes a head body 12 and a striking plate 14. An opening 121 is formed on the front part of the head body 12 and a tab 122 around the opening 121. The striking plate 14 has an outer surface 142 and an inner surface 141 with a welding area (not shown) corresponding to the tab 122 on the rim of the inner surface 141. The tab 122 and the welding area are welded together so as to combine the striking plate 14 and the head body 12.[0005]However, according to the foregoing design of arranging the welding area on the rim of the inner surface, the striking area of the striking plate will be reduced because of the limitation of the welding area to affect the striking function. On the other hand, if the striking pl...

AI Technical Summary

Benefits of technology

"The invention provides a golf club head made by welding a cup face and a head body. The cup face is made by combining at least two different substrates in the explosion welding way, which prevents the high welding temperature from causing the separation of different substrates and improves the quality of the golf club head. The welded areas between the cup face and the head body are far away from the striking area, which expands the striking area and improves the hitting function. The golf club head has better elasticity and can adjust its mass center to increase the striking distance. The invention also provides a golf club head with better striking feeling and elasticity to increase the hitting distance."

Problems solved by technology

On the other hand, if the striking plate is a composite plate which is made by the explosion welding, the combination intensity of the composite plate will be destroyed due to the high welding temperature from the welding area to affect the quality of the golf club head.
