Abstract

A golf club head comprises a main body, a striking plate, and a reinforcing plate. The main body is combined with the striking plate on its face side, and has an annular wall extended backward from the main body. The reinforcing plate is integrally formed on rear surface of the striking plate, and covered around a seam jointed between the striking plate and the annular wall of the main body. Thus, during striking a golf ball, the reinforcing plate can intensify the entire structure of the seam for striking stress, and absorb vibration of the golf club head.

Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a golf club head cover ^ ^ Shibei footbuilding, especially about one: a strengthening plate is provided on the moon surface of h * 墼 plate , ^, Head structure. Golf clubs with increased structural strength [Prior technology] The structure of a Nanlf club head is used, as in No. 1] Gang-Gu Xi # 1 Gedi 1 and 1a, as shown in Figure 1, it is made of metal shells 1 into 1 Talent head 1, the club head J includes a body 10, a dozen 11, a ring wall 12, a set of neck 13 and a shock absorbing sheet 14, the 2 on the front of the body 10 for combating ancient soil. A engine Panel 11 discriminates the ball. The% wall 12 is formed from the week of the book, and then extends to the back. The ring wall 12 surrounds the back to form an opening μ sleeve neck 13 for combining a club [not shown]. The shock-absorbing sheet 4 is made of rubber or carbon fiber material, and can be glued / bonded on the back of the striking panel 11 with an adhesive layer i4i to absorb the vibration generated by the ball. With reference to FIG. 1a, when the above-mentioned striking panel u is bonded to one of the panel joint portions 10 of the body 10 by welding, brazing, or setting or pressing, the striking panel 11 and A joint edge 111 will be formed at the junction of the body 10, such as a welding joint, a brazing flash, a fitting place or a pressing place. When hitting the ball, the shock generated by the hit may cause stress concentration around the joint edge i 丨 1. If the joint edge 111 is subjected to the concentrated stress for a long time, the joint edge 111 may generate cracks, which affects the structural strength of the head 1. Although the conventional head 1 is provided with the shock absorbing sheet i 4, the adhesive bonding method of the shock absorbing sheet i 4 is unavoidable, and it is easy to form a gap between the shock absorbing sheet i 4 and the body i 0. As a result, in practice In use, the shock absorbing sheet 14 cannot absorb the concentrated stress of the bonding edge 丨 1 due to the barrier 142, and the shock absorbing sheet 14

1238075 Amendment No. 92129045 V. Description of the invention (2) 1 4 The efficiency of large vibration is also due to the blocking of the adhesive layer 1 4 1. In addition, because the big hitting towel = absorption, the back of the hitting panel 11,,, j #The back of the panel 11 lacks support k, so that the hitting panel 11 must be shaped like a plane, such as τ 5I to have a larger thickness. In order to ensure that the striking panel 11 does not produce structures due to long-term impact. ^ I retrograde the conventional golf club head

The 'golf of the first embodiment of the present invention' shown in the figure is an integrated gold-made cymbal club head 1, the club head 1 is a cladding plate 15. The body i:-, sleeve neck 13 and-strengthened into a panel combination The part 1 0 1 is summarized as follows: striking the panel H, the striking surface, the plate 11τ is selected to be combined with the panel joint part of the main body 10 by hitting, pressing, welding, screwing, etc., and using one as a whole. The forming method is directly formed on the body 10. The board can be used to hit a golf ball. The ring wall 12 is extended backward from the periphery of the body 10, and the ring wall 12 is surrounded by the back to form an opening 121. The sleeve neck 13 is for combining a club [not shown]. The reinforcing plate 15 is closely attached to the striking panel u in the opening 121, and the whole of the reinforcing fairy is substantially flat. The reinforcing plate 15 preferably uses heat It is made by compression molding or molding, so it can be directly integrated into the back of the punching plate 11. The reinforcing plate 15 is made of lightweight reinforcing material, mountain fiber, resin [such as epoxy resin], and polymer polymerization. Material, = alloy (such as titanium alloy, aluminum alloy) and its viscous composite powder : For surface, the body 10 (excluding the striking panel U) can be used for precision casting, casting, machining, die casting, forging, and injection molding according to demand.

Furthermore, 'as shown in Figure 3a Because the reinforcing plate 5 is hot-pressed or injection-molded, the reinforcing plate 15 can be completely and tightly bonded to the back of the striking panel 11 without the use of an adhesive. Because the reinforcing plate 5 can A covering edge 111 (such as a weld bead, a brazing flash, a fitting place or a pressing place) formed at the boundary of the striking panel 11 and the body 丨 0 is completely covered, so the reinforcing plate 15 can be used when hitting a ball In order to absorb the concentrated stress of the joint edge 丨 丨 J, if to avoid the joint edge 111 from being affected by the concentrated stress for a long time, to strengthen the combination of the striking panel i 丨 and the body ^ and extend the talent head The use of brother's life 1. When hitting the ball, the present invention can use The reinforcing plate 15 directly absorbs the vibration generated by the striking panel u. As a result, the reinforcing plate 15 makes the club head 1 have excellent structural strength and shock absorption effect, and further improves the ball striking stability and holding comfort of the club head 1 "; In addition, since the reinforcing plate 15 also has the function of supporting the striking panel, it is beneficial to reduce the thickness of the striking panel, so as to improve the transient elastic deformation of the striking panel 11.

As shown in Fig. 5a, the reinforcement 15 and the extension 15 1 can also be completely tightly bonded to the back surface of the striking panel n and the inner wall surface of the ring wall 12 without the need for adhesive bonding. In the percentage of hits, it is clear that the reinforcing plate 15 can not only directly absorb the vibration generated by the striking panel 11, but also use the extension 5 1 to absorb the vibration generated by the body W and its surrounding wall 12. As a result, the reinforcing plate 15 can also provide the club head 1 with excellent structural strength and shock absorption effect, and further improve the ball striking stability and grip comfort of the club head 1. Please refer to Figs. 6 and 7, which show the structure of a golf club head according to a third embodiment of the present invention. Compared with the first embodiment, the reinforcing plate 5 of the third embodiment is formed with a deformation hole 152 formed at a position corresponding to the back of the main hitting area of the striking panel 丨. Therefore, when hitting the ball, the deformation hole Η # can make the main hitting area of the striking panel 11 to form the maximum degree of elastic deformation to increase the hitting distance. At the same time, the reinforcing plate 15 can also increase the bonding strength of the striking panel 11 and the body 10, absorb the vibration generated by the hitting ball, and support the striking panel 11. Please refer to Figs. 8 and 9 ', which shows the Gaol = structure of the fourth embodiment of the present invention. Compared with the second embodiment, the fourth embodiment, in addition to forming the strong second plate 15 to form the extension portion 151, it also further forms the deformation hole 152.
