Description of the Invention: [Technical Field of the Invention] The present invention relates to a golf club head, and more particularly to a golf club head structure in which a body is formed of a soft metal and a hitting face and a bottom are integrally formed of a hard metal. 5 [Prior Art] It is known that a golf club head formed of soft metal (such as soft iron) has the advantages of easy neck angle adjustment and good ball control. The disadvantage is that the face line groove is easily damaged by strong hitting, and the bottom is easy to Ground friction is damaged. Strengthening the face is a viable way, for example, forming a striking panel with a hard material and fixing it on the striking surface, but this is detrimental to the ball control. The improved way is to form an eup hitting surface and a cup. The ball striking surface has a point of better flexural elasticity to enhance its ball control. The bottom wear resistance can also be improved by using a harder material λ. However, the hitting panel and the bottom plate of the conventional head are usually arranged in different parts, so the bottom edge of the front end of the soft metal head body is lacking. Protection, easy to damage. SUMMARY OF THE INVENTION The main object of the present invention is to provide a golf club head, which has the double excellent characteristics of a soft metal body and a bottom of a hard metal ball striking panel, and is integrally formed with the hitting surface of the cup and the bottom. The bottom edge of the front end of the head can be well protected. In order to achieve the above, a golf club head according to the present invention includes a body having a body and a neck, which is made of metal 4 200909025; the ball striking member is harder than the body material. Made of metal, having a panel portion and a bottom portion extending rearward from the bottom end of the panel portion - the body forming ball striking member is fixed to the body portion of the body by the periphery thereof, and the top portion of the panel portion and the bottom portion of the bottom portion The position near the panel portion is suspended, and the joint position of the bottom end spot 5 is more than the position of the pole position to the rear side. [Embodiment] The following description is made with the following description: As shown in the first to fourth figures, the head (i 〇) of the first embodiment of the present invention comprises 10: a body (20), A metal material having a hardness (HRC) of 30 or less is integrally molded by casting. In this embodiment, the body is made of stainless steel 3〇4, and its hardness is 5 to 6 (HRC 5 to 6), which is relatively soft and has a body (21). And a neck portion (22) having an upper frame portion (211), a lower frame portion (212), a toe 15 portion (213) and a heel portion (214), and the center has a perforation (215) The ring-shaped frame has a weight portion (216) protruding above the lower frame portion (212). A ball striking member (30) is integrally formed by a hard metal material having a hardness (HRC) of 30 or more, for example, a titanium alloy (for example, stone 6_4 titanium, HRC 30 to 40) or stainless steel 450 (HRC 40~). 42) It is made of stainless steel 174 20 (HRC 30) or aging steel 465, etc., and has a panel portion (31) and a bottom portion (32). The ball striking member (30) is fixed to the upper frame portion (211) of the body portion by the upper edge of the panel portion (31), and has a bottom end edge (32) and a lower frame portion (212) When the weight is fixed, the weight portion (216) extends in the direction of the panel portion (31) and is spaced apart from the panel portion (31) and the bottom portion (32). 5 200909025 That is, the 'Ball member (30) is fixed to the body (21) of the body (2) by its circumference, and the top surface of the panel portion (M) and the top surface of the bottom portion (32) are close to the panel portion. (8) The position is both suspended and the joint position (B) of the bottom end (32) and the body (21) (as shown in the second figure) exceeds the bottom center position (A) of the head (10) and is biased backward. The side elements can be fixed by welding (Weiding) or brazing (brazing) or both. The thickness of the panel portion (31) of the ball striking member (3) is preferably between 1.8 and 3.5 mm to provide sufficient structural strength and flexural elasticity, and the bottom portion (32) is thick at 1 to 2 It can be between 5mm, mainly providing wear resistance. 'Thin thickness provides better flexural elasticity, which makes the ball control of the shot 10 surface better. As shown in the second and fourth figures, in this embodiment, a plurality of ribs (217) are provided at the bottom surface of the weight portion (216) near the lower frame portion (212), and the bottom of the ball striking member (3) is (32). The top end of the tail end is attached to the ribs (217). This structure facilitates assembly work and ensures that the bottom portion (32) is spaced from the weight portion (216). 15 As shown in the second and fourth figures, in this embodiment, a back member (40) is disposed in the middle of the ring frame portion (21) to close the body portion (the hole in the middle of the 2 u (2 work 5), The back part (40) can be made of plastic or fiber-reinforced resin, which can effectively reduce the head weight I and facilitate the design of the trademark or other back shape or pattern on the back part (40), so the manufacturer can easily The change of the back part meets the needs of the buyer of the 20th. As shown in the fifth to tenth drawings, the head (5〇) of the second embodiment of the present invention also includes a body (60) and a hitting ball. Member (7〇). As shown in the ninth and twelfth figures, the top end of the panel portion (71) of the ball striking member (7) extends rearward from a top portion (73) and extends downward from the top end of the top portion (73). One end portion 200909025 (74) is provided with a card slot (741) at the end portion (74), and a convex portion (721) is protruded at the end portion of the bottom portion (72) of the ball striking member (70). The body (60) The upper frame portion (611) of the body portion (61) is provided with a hook (6111), which can be engaged with the aforementioned card slot (741), and the lower frame portion (612) of the body portion (61) is concave. a groove (6121) for inserting the aforementioned convex portion (721) into a card and then hard soldering In combination, the brazing solder fills the gap of the card-incorporating portion, and the joints in the figures 5 to 9 are convex, and these portions are finally polished and polished to show no visible marks. North Second Embodiment There is no perforation in the middle of the body (6)), so there is no separate back part. The top (73) width of this recording example can be set between 5 and 6 sides of the wire, because the top (73) and the bottom (72) are thinner and longer, because the convertible part (7) is larger. The deflection (7) two === slash = will be small, so that the rod is called the thief trousers = the end of the stress relative change 15 200909025 [Schematic description] The first figure is a front view of the first embodiment of the present invention.
