200819174 IX. Description of the Invention [Technical Field to Which the Invention Is Applicable] In particular, there is a three-piece golf club head in which the present invention is related to the Gol & head. [Prior Art] Relatively weighed, the lower the better, the better, so the best _ self-degree, 1: =1:; =: requires a crack, and can hit the ball farther. The spoon has a strong squeezing force to avoid breaking. SUMMARY OF THE INVENTION The present invention is directed to providing a three-to-top lightweight, bottom and: 4-type head structure that achieves excellent elasticity: The wear-resistant property's the hitting surface has 15 but only the different physical properties of the gentleman's eight strong stress' must be structurally = the problem of hitting the ball. In consideration of the combination of different physical materials, the golf club head can also solve the problem of non-sex material, according to the present invention:: package::: a top member, The specific gravity is; the bottom-bottom member is two below the top member; the --facial structure is combined with two; steel; 4 20 200819174 7C kitchen L 吝 4 4 4 4 4 4 α α α α α α

In front. Self-destruction and front of the bottom member. The utility model is provided on the top structure, and the invention adopts 5 彳 at the joint of each member by the gentleman 4»仕^, and the structure is more stable and firm. The embedding stress of the groove and the convex portion is the effect of g. Therefore, the structure is made more stable, and a lighter and thinner device can be obtained. [Embodiment] An embodiment is described with reference to the following figures: As shown, the head of the first embodiment of the present invention (10) The utility model comprises: a top member (20), which is made of a lightweight material having a specific gravity of 3 or less, such as a 15-stage plastic or a carbon fiber reinforced resin or a magnesium alloy or an aluminum alloy, and has a neck (21) and a neck. The part has a shaft hole (22) for inserting a golf shaft (not shown). The bottom member (3〇) is made of a metal material having a specific gravity of 4 or more, such as tantalum alloy or stainless steel or a general iron material or a powder metallurgy tungsten nickel alloy or 20 is a tungsten copper alloy or a combination of the above materials. , located under the top member (20). A face member (40) is made of a resilient metal material such as titanium alloy or stainless steel or aging steel, has a ball striking face (41), and extends backward from the ball striking face to form a crotch portion ( 42), the overall cup shape, located in front of the top member (20) 5 200819174 and the bottom member (30). wH — riding, at the top member (2G) and the bottom member (10). 2 = There are grooves (23) and projections (31) that can be engaged with each other. At the joint portion of the face member (4) == member (2〇) and the bottom member (10), convex portions (43) and grooves (24) (32) which are contiguous with each other are also provided. By virtue of the Leica structure of the projections and grooves, the members of the present invention can be joined by either (Brazing) or an adhesive (e.g., epoxy). For example, the P component (2〇) uses a magnesium alloy with shock absorbing properties, and the face is used with 15 = better elastic and lightweight titanium alloy' and the bottom member (3_ uses stainless, ''recording weight and resistance) The characteristics of the mill. Because the magnesium alloy has a low glare point and is not suitable for use in brazing or general welding, it is only bonded by an adhesive, because the components have a snap-fit structure between the components, and the neck design of the present invention is On the top member, the stress generated during the shot will force the face member to press against the top member and the bottom member, and the annular crotch portion of the face member will also constrain the top member and the bottom member. The entire head is joined without cracks, and because of this structural design, the top member can even be made of a plasticized material such as engineering plastic or carbon fiber reinforced resin, making it lighter. As shown in the third figure, the face member The distance (w) of the crotch portion (42) of the (40) from the ball striking face (41) 20 to the outer end of the crotch portion is equal to or greater than 8 mm, preferably (7) mm, and the crotch portion (42) Thick part D is equal to or less than 2 mm, so that The crotch portion (42) substantially forms a long and thin leaf spring effect. When the ball is hit hard, the ball striking surface (41) of the face member (40) is elastically flexed and deformed by the impact force path. Involving the ridge portion (42) with the flexing deformation and affecting the joint end, the present invention designs the shank portion (42) into a thin shrapnel shape, thereby allowing the crotch portion to generate a large amount of elastic deformation, The joint end can withstand relatively stress (because the stress first causes the jaw to flex and deform rather than directly to the joint jaw, that is, the face member adopts a flexible structure design instead of a rigid structure design) It will be broken, so that the joint end of the top member can be designed with a thinner and lighter structure, so as to avoid the structural weight and thickness, which further strengthens the flexible structure of the head and makes the head better. The shock absorbing characteristic, the joint end of the top member (2〇) of the embodiment of the present invention adopts a groove (24) design, and the thickness 8 of the groove from the outer side wall surface to the groove groove wall is less than 3 mm, the present embodiment The thickness S of the example is 丨·5 mm. It can be used so thin. The thickness without cracking is still due to the design of the thin shrapnel in the crotch (42). As shown in the fourth figure, since the top part of the head is made of lightweight material, we can use the neck shaft. A pipe fitting (25) is inserted into the hole (22), and the I5 is used for partial reinforcement. The pipe fitting (25) can be used for bribes. The magnesium alloy is made of titanium alloy or non-mineral steel or engineering plastic. In the fifth figure, the bonding strength between the top member (2〇) and the bottom member (3〇) is increased, and the bottom member (3〇) corresponds to the neck member of the top member (10). ), and the _ bolt (10) is screwed into the screw hole 4) of the joint portion (10) through the neck shaft 2〇=end preset hole (10), and the secret top member is screwed to the bottom member. Thereby, the bottom, the cow (10) is connected with the shaft of the golf ball, so the #head is shoveled to the grass ^, the stress part of the bottom member is found to be transmitted from the riding connection portion to the shaft shaft 'effectively reducing the joint end of the bottom member and the top member The stress that is withstood. 7 200819174 [Simplified description of the drawings] The first figure is a perspective view of an embodiment of the present invention. The second figure is a cross-sectional view taken along line 2-2 of the first figure. The third figure is an enlarged view of the circled portion in the second figure. The fourth figure is a cross-sectional view taken along line 3-3 of the first figure. The fifth figure is similar to the fourth figure and shows the further joining structure of the top member and the bottom member.
