Abstract

A golf club head includes a ball head body with a lower surface facing downward, and a sole plate disposed on the lower surface of the ball head body. The bottom plate includes a plate body made by electroforming, and an electroplating layer plated on the plate body. The bottom plate is exposed at the bottom surface of the golf club head. Due to the characteristics of the plate body made by electroforming, the thickness of the plate body can be uniform and the texture or appearance design can be more detailed, so as not to produce casting defects and to be able to To improve the overall texture, the soleplate also has the characteristics of high brightness and wear resistance, which makes the appearance of the underside of the golf club head to a higher level.

Description

golf club head

The present invention relates to a golf club component, in particular to a golf club head.

Golf is a popular ball game in the world, which is played by hitting a golf ball with a golf club. A golf club consists of a shaft and a head, in which the head affects the hitting performance of the entire golf club, which can be said to be the soul of the club, but in addition to practicality, the appearance of the golf club head is often a consumer A very important part, and the bottom surface of the club head is not directly involved in hitting the ball, so it has become a part that can make a big fuss. At present, the bottom surface of the golf club head is mostly formed by casting or forging, but the former is easy to be in the casting process. There are many casting defects in the bottom surface of the club head, which affect the final appearance of the bottom surface of the club head, while the latter is limited by the forging technology, and it is difficult to present a more detailed pattern or shape design on the bottom surface, so there is still room for improvement.

Therefore, the purpose of the present invention is to provide a golf club head with a high wear resistance, high brightness, and high fineness of the outer surface.

Therefore, the golf club head of the present invention includes a ball head body having a lower surface facing downward, and a sole plate disposed on the lower surface of the ball head body. The bottom plate includes a plate body made by electroforming, and an electroplating layer plated on the plate body.

The effect of the present invention is that the bottom plate is exposed at the bottom surface of the golf club head, and the plate body is made by electroforming, so that the thickness can be uniform and the texture or appearance design can be more detailed, so as to avoid Casting defects can occur and the overall texture can be improved, and the soleplate is also characterized by high brightness and wear resistance, which enhances the appearance of the underside of the golf club head.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are designated by the same reference numerals.

Referring to FIG. 1 , FIG. 2 , and FIG. 3 , a first embodiment of a golf club head of the present invention includes a head body 1 and a sole plate 2 disposed on the head body 1 . The ball head body 1 has a lower surface 11 facing downward. It should be noted that the downward direction referred to here refers to the direction in which the golf club head is generally held, which is up and down opposite to the direction shown in the drawings of this pattern. The bottom plate 2 includes a plate body 21 whose inner surface is glued to the lower surface 11 and is made by electroforming, an electroplating layer 22 plated on the outer surface of the plate body 21, and a plate body 22 formed by physical vapor deposition ( PVD) the outer plating layer 23 formed on the plating layer 22 . In the first embodiment, the total thickness of the sole plate 2 is 0.1 mm to 0.5 mm, so as not to make the golf club head too thick as a whole. The material of the plate body 21 may be nickel or a nickel-cobalt alloy with higher hardness, and the material of the electroplating layer 22 may be chromium or a nickel-chromium alloy.

The manufacturing method of the first embodiment is as follows: electroforming nickel or nickel-cobalt alloy to manufacture the plate body 21 , then electroplating chromium or nickel-chromium alloy on the plate body 21 to form the electroplating layer 22 , and then depending on the The surface color is required to form the outer plating layer 23 on the electroplating layer 22 by physical vapor deposition, so as to obtain the sole plate 2, and finally the sole plate 2 is glued to the lower surface 11 to prepare the golf club head . It should be noted that, the bottom plate 2 may not form the outer plating layer 23 on the plating layer 22 as appropriate.

The plate body 21 has the characteristics of electroforming to avoid casting defects on the surface, and also has a uniform thickness and can form finer lines or appearance designs on the surface, so as to produce high wear resistance and high brightness on the bottom of the golf club head. , and high-definition appearance modeling. When the ball head body 1 is made of titanium, the specific gravity of the plate body 21 will be higher than that of the ball head body 1, so the sole plate 2 can be used as a counterweight for lowering the center of gravity of the golf club head, increasing its function sex.

Referring to FIG. 4, it is a second embodiment of the golf club head of the present invention. The second embodiment is substantially the same as the first embodiment, except that the ball head body 1 further has a And surrounding the hollow groove 12 of the lower surface 11 , the plate body 21 of the bottom plate 2 is not directly bonded to the lower surface 11 . The bottom plate 2 further includes a thin plate 24 embedded in the hollow groove 12 and glued to the lower surface 11 on the inner surface. The second embodiment can be applied to the ball head body 1 with a hollow bottom design, and the thin plate 24 made of carbon fiber is used to achieve a reinforced structure and take into account the function of light weight.

To sum up, the present invention can avoid casting defects, and can produce high wear resistance, high brightness, and high fineness appearance on the bottom surface of the golf club head, so it can indeed achieve the purpose of the present invention.

However, the above are only examples of the present invention, and should not limit the scope of the present invention. Any simple equivalent changes and modifications made according to the scope of the application for patent of the present invention and the content of the patent specification are still within the scope of the present invention. within the scope of the invention patent.
