[Technical field to which the invention belongs] The present invention relates to a golf club head, in particular to a golf club with a U-shaped or L-shaped cross-section hitting panel that can form a high-hitting ability and high-strength heterogeneous material with a club body. Head structure. [Prior art] Conventional club heads are used, such as the Republic of China Announcement No. 4691 43 "Addition of a new method for joining golf talent head shells and batting panel pieces", the invention patent office, which includes a head shell And a batting panel. The head shell is provided with a groove from the spherical position, and the hitting panel is embedded in the head shell plate and the groove. Before the hitting panel piece is inserted into the head housing groove, the brazing solder is placed in the two grooves, and then the hitting panel piece is embedded in the I groove. Then, the solder is melted by heating to make the hitting The ball face plate is firmly connected to the head housing. Although the above-mentioned embedding and brazing methods can fit the ball striking face on the head shell, the brazing process cost is relatively high. The outer peripheral edge of the key 疋 'is directly bonded to the inner peripheral surface of the groove, and the above-mentioned setting limits the elastic deformation ability of the impact panel. "It is expected that another conventional golf club head, as described in the new patent of the Republic of China No. 552988" Golf Ductile Iron Head Structure ", includes a club body, a face, and a face plate. The head body is recessed to form a groove seat, and the periphery of the groove seat is a ring lip. The striking panel is formed by bending the body to form a bent edge and a Xin 2 wall, and the bottom of the ring wall can be correspondingly welded to the ring of the head body. Second, the reason is that the striking panel has a large shot area. The maximum elastic deformation can be obtained by the bend and the wall, so that the iron-type head is suitable for hitting the ball. , ·

Description of the invention (2) In the process of shell IV and group I, the head body and the striking surface are changed in 3D, so the head body and the standing position = Cheng: However, this action caused the rod Head 丄 ;; deviation of defective products. In addition, the head body and impact = ;; = ;: =: sex are made of materials that can be combined using high energy welding, argon welding, and the like [welding]. If the head body and the striking panel are made of dissimilar materials (such as stainless steel and titanium alloy) with low welding compatibility, it is necessary to abandon the low-cost welding process and use the high-cost brazing process [brazing]. In addition, this type of striking panel structure does not have a combination of other options. On the other hand, due to its special specifications, this type of striking panel is only suitable for use with the head body assembled in a specific corresponding specification. It is assumed that if this type of striking panel can be applied to various existing club head specifications and overcomes the technical problem of reliability, it is expected that the long-range hitting ability of golf club heads will be greatly improved. In view of this, the present invention improves the above-mentioned shortcomings. It is a U-shaped or [disc cross-section strike plate disposed in a groove of a club head body, and various combinations can be used to form a high-strength Proper joint. Therefore, the present invention can not only improve the elastic deformation ability of the panel, but also increase the margin of the joint design, increase the joint strength, reduce the stress concentration, increase the range of materials, and extend the service life. [Summary of the Invention] The main object of the present invention is to provide a golf club head which is embedded in a groove of a club head body with a striking panel having a U-shaped or L-shaped cross section,

Description of the invention (7) In the positioning space formed by the clamping strip 113 of the two-head body 1 and the stepped portion U1, :: a welding electrode 60 is placed on the filler empty Fa1e. In the case of heating and brazing, the dome 60 melts into molten iron and fills the filler space e by using a capillary phenomenon. After brazing, a cymbal joint 6 is produced, which can be used to combine the head body i and the striking panel 2 with low compatibility of different materials. In short, the structure of the head body 1 and the striking panel 2 of the present invention is also applicable to the brazing process to meet different product and design requirements. At the same time, the striking panel 2 with a U-shaped section also maintains high elastic deformation capacity, so it can also improve the overall Batting performance and extended life. The method is integrated in the groove ^ of the head body 1. As a result, the shape of the striking surface is more suitable for manufacturing with a low-cost stamping method. At the same time, the striking panel 2 with a u-shaped section also maintains high elastic deformation ability, so it can also improve the overall striking performance and prolong the service life. Please refer to FIG. 9 for a golf club head according to a sixth embodiment of the present invention. Compared with the fifth embodiment, the striking panel 2 of the sixth embodiment only forms a bent edge 21 and a supporting leg 22, and the supporting leg 22 can be optionally formed on the bottom side of the striking panel 2 [s 〇1 e] , The top side [b 1 ade], the heel a side or the toe b side. In addition to the bent edge 2 丨, the other peripheral edge of the striking panel 2 forms a notched edge 2 5; the groove 11 of the head body 1 corresponds to that shown in FIG. 8, which discloses the fifth aspect of the present invention.
