Abstract

A golf club head comprising a club head body having a lower surface facing downward, and a base plate disposed on the lower surface of the club head body. The base plate includes a plate body made by electroforming and an electroplated layer electroplated to the plate body. The base plate is exposed on the bottom surface of the golf club head. The characteristic that the base plate is fabricated by electroforming provides uniform thickness and finer texture or appearance design, thereby avoiding casting defects and enhancing the overall quality. The base plate further has the characteristics of high brightness and wear resistance, which makes the appearance of the bottom surface of the golf club head to a higher level.

Description

golf club head

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

Golf is a kind of ball game that is popular all over the world, and it is carried out by hitting a golf ball through a golf club. A golf club consists of a club body and a club head. The club head affects the hitting performance of the entire golf club. It can be said to be the soul of the club. It is 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 formed in the casting process. There are more casting defects in the club head, which affect the final appearance of the bottom surface of the club head. However, the latter is limited by forging technology, and it is difficult to present more detailed textures or shape designs on the bottom surface, so there is still room for improvement.

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

Therefore, the golf club head of the present invention includes a ball head body with a lower surface facing downward, and a soleplate 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 base 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 can be uniform and can have a more detailed texture or appearance design, so as not to Eliminating casting defects and improving the overall texture, the soleplate is also characterized by high brightness and wear resistance, which enhances the appearance of the sole surface of this golf club head.

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

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

The manufacturing method of the first embodiment is: 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 Surface color requirements The outer coating 23 is formed on the electroplating layer 22 by physical vapor deposition to obtain the bottom plate 2, and finally the bottom plate 2 is bonded to the lower surface 11 by gluing to obtain the golf club head . It should be noted that the bottom plate 2 may not form the outer plating layer 23 on the electroplating layer 22 as the case may be.

The plate body 21 has the characteristics of electroforming to avoid casting defects on the surface, and at the same time has a uniform thickness and can form finer lines or appearance designs on the surface, thereby producing high wear resistance and high brightness on the bottom of the golf club head , and high-definition appearance. When the material of the ball head body 1 is titanium metal, the specific gravity of the plate body 21 will be higher than that of the ball head body 1, so the bottom plate 2 can be used as a counterweight to lower 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, the difference is that: the ball head body 1 also 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 also includes a thin plate 24 embedded in the hollow groove 12 and glued to the lower surface 11 on the inner surface. The thin plate 24 is made of carbon fiber, and the outer surface of the plate body 21 is glued. The second embodiment can be applied to the ball head body 1 with a hollowed-out bottom, and the thin plate 24 made of carbon fiber can be used to strengthen the structure and take into account the functions of light weight.

To sum up, the present invention can avoid casting defects, and produce high wear resistance, high brightness, and high-precision appearance on the bottom surface of the golf club head, so the purpose of the present invention can be achieved.

But what is described above is only an embodiment of the present invention, and should not limit the scope of the present invention. All simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention. Within the scope covered by the patent of the present invention.
