1324939 IX. Description of invention:

[Technical field to which the invention pertains]

The invention relates to a Gore wood head device and a method for manufacturing a shock absorbing material on the inner side of a ball striking surface, which means a shock absorption and a center of gravity deep: the height of the center of gravity is low, and the ball is hit by the swing. A golf club head that emits a crisp sound to meet the hitting needs of golfers. [Prior Art]

Golf has gradually become one of the popular rest games, and golf equipment has gradually gained attention due to the popularity of golf. In the high-in-arms, the most important first golf club, the goodness of a club will affect the stability of the ball and the state of the ball after the ball, and the club is important to the result of the hit. One of the first pushes the ball head set at one end of the club. Most of the traditional golf club heads are hollow, and the structural design of the ball striking surface is easy to change the shape of the ball body to produce a resonance sound. However, because the sound can be generated, the ball head will be A large vibration occurs when hitting the ball. 'The shock wave generated by this kind of vibration is transmitted to the player's hand through the shaft, which makes people feel uncomfortable. Therefore, the inventor has this problem. R&D and improvement, such as the Republic of China Patent Certificate No. 1227156 (hereinafter referred to as Reference 1), please refer to the figure shown in Figure 8, which is formed on the body of the golf head (70) immediately adjacent to the ball striking panel (74). A spacer (72)' forms a chamber (73) between the spacer (72) and the ball striking panel (74), and the shock absorbing material is injected into the chamber to fill and adhere to the chamber. (7 3) Internally, the shock wave generated when the batting panel (7 4 ) hits the ball can be directly absorbed by the shock absorber 1324939 material, and it achieves a good shock absorption effect.

However: the reference one of the ball head thin cover (7i) l body-body molding' must be formed by thin plate and then welded to the ball head: On, the welding will cause the inner bead to increase the center of gravity of the ball And the partition plate (2) is directly cast and molded on the periphery of the ball-face welding hole (5) of the body of the golf ball head. Although the strength is good, the metal solution cannot form a too thin peripheral wall. Therefore, the strength of the groove structure is better, and the thickness of the partition plate (72) is not so easy to be deformed, so that the bellows generated when hitting the ball is inferior, so that it is less likely to emit a light and crisp sound. Another inventor's research and development and improvement case, such as the Republic of China Patent Certificate No. I 2 2 8 0 5 2 (hereinafter referred to as Reference Case 2), please refer to the ninth figure, which is hollow in one piece. The inner side of the golf head (8 〇) is provided with a receiving groove (8 working), a shooting hole (82) and a venting hole (83) for filling or injecting. Appropriate weight and volume of shock absorbing material (84), can make the golf head (8 〇) can produce sound when hitting the ball at the same time, and has the appropriate shock absorption effect, so as to make the shock after the ball Reduced to an appropriate level. However, 'the reference case·one shock absorption structure can remove all unnecessary vibration noises', leaving a crisp resonance sound, making the sound of the ball head more pleasant and simple, but its shock absorption effect is better than the reference case Poor, so there is still room for improvement in order to achieve a good shock absorption effect and a soft and crisp sound when the swing is hit. SUMMARY OF THE INVENTION The present invention is designed to improve the mutual deficiencies of the two references. In order to achieve the golf ball that can be light and brittle when hitting the ball = fruit 'to meet the hitting feeling required by the player 2 based on the above purpose, the technical means of the present invention mainly provide a kind of inside the ball striking face The golf club head device of the shock absorbing material comprises: a ball head n' is a hollow metal shell 'on the side wall of the ball head body side - a ball striking face welding hole communicating with the inside of the ball head body;

The outer panel of the batting panel is correspondingly embedded in the welding surface of the batting surface, and the panel of the batting panel is composed of a smashing nn ^ ^, and the surface of the panel is composed of a grooved plate and a grooved plate. The thickness of the thin metal plate is 0. 2mm to 〇. 5mm, the grooved thin plate is located at the rear side of the ball striking face, and a groove space is formed between the groove thin plate and the ball striking panel, and the groove space is formed in the groove space The shock absorber is provided, and the shot hole panel is provided with a shot hole and at least one overflow hole communicating with the cavity space, and the shot hole and the overflow hole are designed as a small aperture (the hole diameter of the injection hole is 1 . 5mm to 2. 5mm, the aperture of the overflow hole is 〇. 4mm to 〇.

• I Mil II j J-J1 Ι··ι· —HT — "June 6"] The daily (^) replacement page 8mm), in addition to facilitating the injection and overflow of shock absorbing materials, can also complete the shot After entering the shock absorbing material, the spot welding seal on the surface of the hitting panel has a small aperture, so the heat conduction is extremely small and does not damage the processing work of the shock absorbing material. The invention also relates to a shock absorbing material disposed on the inner side of the hitting surface. The method for manufacturing the golf club head device is to provide a ball striking face welding hole corresponding to the ball striking face at the ball head body of the golf club head, and an outwardly protruding welding lip is arranged on the periphery of the striking face welding hole. Another set of the hitting panel consisting of the hitting panel and the grooved thin plate is made of a thin metal plate, and a space is formed between the hitting panel and the grooved thin plate, and the hitting panel 1324939 On the 1st day of the revised replacement page, there is also a shot hole and at least one overflow hole that communicate with the trough space. The main purpose of the hole is to fill and adhere the injected shock absorber: 4曰工室_, can be sure to completely fill the trough space from a little shock absorber Also, the cb 4 error can be obtained by the setting of the overflow hole, and all the air in the container space is discharged by the way. The flat panel is fixed to the welding surface of the ball striking face, and the welding lip is directly used as the welding lip. The solder welds the outer peripheral edge of the hitting panel group, and then the movable nozzle is disposed on the screwing seat of the shooting hole at the surface of the hitting panel, so that the movable nozzle can inject the shock absorbing material into the accommodating space β, and then Removing the reusable screw seat and the movable nozzle', and then sealing the shot hole and the overflow hole by spot welding, the projecting hole and the material hole of the overflow hole, and the welding The bead of the lip is: After the above technical means, the specific benefit obtained by the invention is 1. The invention is formed between the rear side of the hitting panel and the grooved sheet - the grooved space is made to fill the shock absorbing material And adhered to the pocket space 0, because the structural design of the hitting panel group has a large deformation amount, it is easy to affect the deformation of the ball head body. Therefore, when hitting the ball, a good bellows effect can be formed inside the ball head body. Light and crisp sound to meet the hitting needs of golfers 2. Since the structural design of the hitting panel group has a large deformation amount, although the area of the shock absorbing material changes,], but the larger deformation amount when hitting the ball is easy to affect the middle shock absorbing material, and then the shear deformation generates the grinding.帛 Converts the absorbed kinetic energy into heat and dissipates quickly to achieve better absorption vibration.

|/|内月^曰修(今正普换 I __ 1 1 — 3 . Because the grooved plate is designed to be lighter, and the ball body can be designed to be integrally formed. The weld bead, when combined, can make the center of gravity of the ball head deeper, the height of the center of gravity becomes lower, and the solidity of the ball is raised.
