Description

golf head

technical field

The utility model relates to a golf head, and in particular to a golf head with a relatively high moment of inertia (Moment Of Inertia, MOI).

Background technique

Golf is one of the common leisure activities, and the ball heads of golf clubs with different functions are designed in different ways. For example, a driver has to hit the ball far, so the design of the shaft is longer and the volume of the head is larger. In addition, since the golf ball is placed on the pegs at the beginning of teeing off, it is easier for the user to hit the sweet spot.

Once the golf ball enters the fairway, the user will use the Fairway Wood to hit the ball. However, since the golf ball is on the ground at this stage, it is less likely for the user to hit the sweet spot and cause the head to spin. Therefore, how to obtain a higher moment of inertia (Moment Of Inertia, MOI) while lowering the center of gravity of the ball head has become one of the development focuses of the related industry.

Utility model content

Therefore, an object of the present invention is to provide a golf head with a deep, low center of gravity and a large moment of inertia.

An elastic member is disposed in the gap.

According to an embodiment of the present invention, the material density of the above-mentioned body is in the range of 4.3 g/cm ³ to 4.8 g/cm ³ , and the material density of the bottom plate is above 7.0 g/cm ³ .

According to an embodiment of the present invention, the above-mentioned body is a titanium body, and the bottom plate is a stainless steel bottom plate.

According to an embodiment of the present invention, the above golf head includes a plurality of locking pieces. The locking piece is arranged on the peripheral edge of the part of the bottom plate away from the ball-hitting panel, so that the bottom plate closes the opening.

According to an embodiment of the present invention, the above-mentioned bottom plate only covers a part of the elastic component.

According to an embodiment of the present invention, the above-mentioned body has a first bent portion, which is disposed on the periphery of the bottom opening close to the ball-hitting panel.

FIG. 3 is a schematic cross-sectional view of a golf head according to an embodiment of the present invention.

Detailed ways

Please refer to FIG. 1 to FIG. 3 at the same time, wherein FIG. 1 to FIG. 3 are respectively a three-dimensional schematic view, an exploded schematic view and a cross-sectional schematic view of a golf head according to an embodiment of the present invention. The golf head 100 of this embodiment mainly includes a double density shell 200 , an elastic member 300 and a plurality of locking pieces 400 . The double density housing 200 includes a body 210 and a bottom plate 220 .

In this embodiment, the body 210 is an open shell with a top 211 , a ball striking panel 212 , a bottom 213 , and a stem 214 . Wherein, the ball hitting panel 212 is located between the top 211 and the bottom 213 , the rod portion 214 is located on one side of the top 211 , and the bottom 213 has an opening 213 a. To clarify, the definitions of the aforementioned "top", "bottom" and "sole" are based on the orientation of the golf head 100 in actual use (such as the orientation in Figure 3), not as shown in Figures 1 and 2 orientation. That is to say, the viewing angles shown in FIG. 1 and FIG. 2 are mainly for clearly illustrating the design of the present utility model, and are not actual angles in use.

Please continue to refer to FIG. 1 to FIG. 3 , the bottom plate 220 is connected to the bottom 213 of the main body 210 and covers and closes the opening 213 a of the bottom 213 . In this embodiment, the material density of the bottom plate 220 is greater than that of the body 210 . Specifically, the center of gravity of the overall golf head 100 can be adjusted through the combination of the lighter body 210 and the heavier bottom plate 220 . In one embodiment, the material density of the bottom plate 220 is above 7.0 g/cm ³ , and the material density of the body 210 ranges from about 4.3 g/cm ³ to about 4.8 g/cm ³ . In one example, the bottom plate 220 is a stainless steel bottom plate, and the body 210 is a titanium body. Thereby, through the design that the material density of the bottom plate 220 is greater than the material density of the body 210, the center of gravity of the overall golf head 100 can be shifted downward, thereby making it easier for the golf head 100 to hit a golf ball on the ground. Heart. In other examples, the body 210 can also be a stainless steel body, and the bottom plate 220 can be a tungsten-nickel alloy bottom plate to meet different usage requirements. Alternatively, in some examples, body 210 may be a carbon fiber composite body. In other embodiments, the ball striking panel 212 itself is an independent component, or may be a part of the body 210 . For example, the ball striking face plate 212 may be a single metal component, or alternatively, the ball striking face plate 212 may be part of an integrally cast formed body 210 . In a specific example, the top 211 , the bottom 213 , and the stem 214 of the body 210 are integrally formed carbon fiber composite structures.

As shown in FIGS. 1 to 3 , in this embodiment, the bottom plate 220 is locked on the main body 210 through the locking member 400 . Specifically, the part of the bottom plate 220 away from the ball striking panel 212 is connected to the bottom 213 of the main body 210 through the locking member 400 . In some examples, the locking member 400 can be a screw. In this embodiment, the function of the locking member 400 is not only to fix the bottom plate 220 on the body 210, but also has the function of counterweight. By fixing the locking member 400 on the part of the bottom plate 220 away from the ball hitting face plate 212, the center of gravity of the golf head 100 can be shifted away from the ball hitting face plate 212. The double-density shell design makes the overall center of gravity of the golf head 100 low and deep, thereby increasing the overall moment of inertia (Moment Of Inertia, MOI) of the golf head 100, so the golf head 100 is less likely to appear when hitting the ball. Twist, thus making the hitting distance and direction more stable.

In some embodiments, the quantity and material of the locking member 400 can be determined according to usage requirements or different design requirements. The locking elements 400 of different materials have different densities and weights, so users with different needs can choose different materials and quantities of locking elements 400 to obtain different golf head designs. To clarify, in the aforementioned embodiments, the connection between the main body and the bottom plate is not limited to the engagement of the fasteners. In other embodiments, the bottom plate can also be joined to the main body by welding or bonding, so that the use of locking pieces can be omitted.

In this embodiment, the elastic member 300 can be arranged in the gap G. The elastic member 300 can not only absorb the shock force generated by the golf head 100 when hitting the golf ball, but also increase the rebound force when hitting the ball. This in turn improves batting performance. In addition, the elastic component 300 can also change the audio generated by the golf head 100 when the ball is hit, so as to bring a better sound when hitting the ball. On the other hand, the elastic member 300 has the function of closing the bottom 213 of the main body 210 to prevent foreign matter such as sand, grass and the like from entering the golf head 100 . In some specific embodiments, when the materials of the body 210 and the base plate 220 are both metal, the elastic component 300 can block and absorb the impact force generated by the two metal materials when hitting a ball, so as to avoid deformation of the metal.

In a specific embodiment, as shown in FIG. 2 and FIG. 3 , the body 210 has a first bent portion 215 , and the first bent portion 215 is disposed on the periphery of the opening 213 a of the bottom 213 near the ball striking panel 212 . The bottom plate 220 has a second bent portion 221 , and the second bent portion 221 is disposed on a portion of the bottom plate 220 close to the ball hitting panel 212 . Wherein, the aforementioned gap G is formed between the first bending portion 215 and the second bending portion 221 . In this embodiment, the section of the elastic member 300 is C-shaped, and it covers the end of the second bent portion 221 of the bottom plate 220 , thereby. Through the design of the first bending portion 215 and the second bending portion 221 together with the elastic member 300 , the body 210 and the bottom plate 220 can be positioned and fixed to each other without using additional fixing elements such as glue or screws.

In this embodiment, a part of the elastic component 300 is located in the gap G, and another part is located outside the bottom plate 220 . That is to say, the bottom plate 220 only covers a part of the elastic component 300 , but does not completely cover the elastic component 300 . The partially exposed design of the elastic component 300 can provide assemblers to quickly check whether the elastic component 300 is installed, and the user can also know whether the elastic component 300 is damaged. In addition, the partially exposed design of the elastic component 300 can also be used as the appearance of the golf head 100 to increase the visual variety of the product.

In one embodiment, the material of the elastic component 300 can be non-metallic materials such as rubber, plastic, or silicone. In a specific example, the material of the elastic component 300 may be thermoplastic polyurethane (Thermoplastic Urethane, TPU) material.

From the above-mentioned embodiments of the utility model, it can be seen that the utility model mainly forms a double-density casing through the sub-design of the body and the bottom plate, which can change the center of gravity of the golf head as a whole, thereby making it easier for the golf head to hit the The center of the golf ball on the ground. On the other hand, by attaching the locking piece to the peripheral edge of the bottom plate away from the ball-hitting panel, the center of gravity of the golf head can be shifted away from the ball-hitting panel, thereby increasing the overall moment of inertia of the golf head , thus making the hitting distance and direction more stable.
