Therefore, an object of the present disclosure is to provide a golf club head cover and a golf club head, which can reduce the overall thickness and improve the overall structural strength through the rib structure design of the golf club head cover.

In accordance with the above objects of the present disclosure, a golf club head cover is provided. The golf club head cover is configured to be mounted on a head body of a golf club head, wherein the head body has a striking face. The golf head top cover comprises a non-metal top cover body and a plurality of convex rib structures. The non-metallic header body has opposing outer and inner surfaces. Rib structures are provided on the inner surface, wherein each rib structure has a height, and the heights are varied as a function of the distance between the rib structure and the striking face.

According to an embodiment of the present disclosure, a height of the rib structure closer to the striking surface is smaller than a height of the rib structure farther from the striking surface.

According to an embodiment of the present disclosure, a surface of each rib structure close to the striking surface has a slope, wherein the slope of the surface of the rib structure close to the striking surface is more gradual than the slope of the surface of the rib structure far from the striking surface.

According to an embodiment of the present disclosure, the non-metallic cap body is a shell structure formed by stacking an appearance layer and a plurality of unidirectional fiber layers.

According to an embodiment of the present disclosure, the unidirectional fiber layers include a plurality of first directional fiber layers and a plurality of second directional fiber layers, wherein a fiber extending direction of the first directional fiber layers is perpendicular to a normal direction of the striking face, and a fiber extending direction of the second directional fiber layers is parallel to the normal direction of the striking face, wherein one of the first directional fiber layers is adjacent to the appearance layer.

According to an embodiment of the present disclosure, the non-metallic top cover body is a shell structure formed by stacking an appearance layer, at least one metal sheet structure, and a plurality of unidirectional fiber layers, wherein the metal sheet structure is disposed between adjacent unidirectional fiber layers.

According to an embodiment of the disclosure, the non-metal top cover body is a shell structure formed by laminating an appearance layer, at least one metal sheet structure, and a plurality of unidirectional fiber layers, wherein the metal sheet structure is disposed between the appearance layer and the unidirectional fiber layer adjacent to the appearance layer, and a portion of the metal sheet structure is exposed out of the appearance layer.

According to an embodiment of the present disclosure, the metal sheet structure is located at a portion of the non-metal top cap body near the striking area, and the inner surface of the portion of the non-metal top cap body is not provided with the rib structure.

Detailed Description

Referring to fig. 1, a schematic structural diagram of a golf club head according to an embodiment of the present disclosure is shown. The golf club head 100 of the present embodiment mainly includes a head body 210 and a golf club head cover 300. The ball head body 210 is a hollow shell, and the top of the ball head body 210 has an opening 211 communicating with the inner space thereof. Wherein, one side of the ball head body 210 is provided with a striking surface 212. The golf head cover 300 is disposed on the top of the head body 210 and covers the opening 211. In some embodiments, the ball head body 210 and the ball striking surface 212 of the present disclosure may be made of titanium or stainless steel.

Referring to fig. 2 and 3 together, wherein fig. 2 is a bottom view illustrating a golf head cover according to an embodiment of the present disclosure, and fig. 3 is a partial sectional view illustrating a golf head cover according to an embodiment of the present disclosure. In the present embodiment, the golf club head cover 300 includes a non-metal cover body 310 and a plurality of rib structures 320. The non-metallic header body 310 has an outer surface 311 and an inner surface 312 opposite the outer surface 311. Wherein the inner surface 312 is a surface facing the inner space of the head body 210 when the golf head cover 300 is mounted on the head body 210 as shown in fig. 1. The bead structure 320 is disposed on the inner surface 312 of the non-metallic header body 310.

In the present embodiment, each of the rib structures 320 has a height, and the heights are changed according to the distance between the rib structure 320 and the striking face 212. As shown in fig. 2, the edge 313 of the non-metallic cap body 310 is the side closest to the ball striking face 212. Taking fig. 3 as an example, the rib structure 320 mainly includes a rib structure 321, a rib structure 322, and a rib structure 323, wherein the rib structure 321 is closer to the striking surface 212 (i.e., the edge portion 313 of the non-metal top cover body 310), the rib structure 323 is farther from the striking surface 212, and the rib structure 322 is located between the rib structure 321 and the rib structure 323. Wherein the height H1 of the rib structure 321 closer to the ball striking face 212 is less than the height H3 of the rib structure 323 farther from the ball striking face 212. In one embodiment, height H1, height H2, and height H3 range from 0.2mm to 0.5 mm. In one embodiment, the height H2 of the bead structure 322 between the bead structures 321 and 323 can be between the height H1 and the height H3. In other embodiments, the height H2 of the rib structure 322 can be equal to the height H1 or equal to the height H3. Therefore, through the way that the height of the rib structure 320 gradually changes along with the change of the distance from the striking surface 212, the strength of the whole golf head cover 300 can be changed, so that the golf head cover 300 can bear different striking powers under the condition of thinning the thickness. In order to test the strength of the golf club head cover 300 according to the present embodiment, after the golf club head cover 300 is mounted to the head body 210, a shot test of a ball speed of 55m/s is performed on the striking surface 212 of the head body 210, and after 3000 shots of the test, the golf club head cover 300 can still pass a flaw detection test. This means that the golf head cover 300 has advantages of both thin thickness and high strength.

It should be clear that fig. 3 is a diagram of the rib structure 321, the rib structure 322 and the rib structure 323 for distinguishing the rib structures with different distances from the striking surface 212, and the disclosure is not limited thereto. In some embodiments, the number, shape, arrangement spacing or height of the rib structures 320 can be varied according to requirements.

Referring to fig. 2 again, in the present embodiment, the rib structures 320 are arranged in a honeycomb shape, and the rib structures 320 have a distance from the edge 313 of the non-metal top cover body 310. In other embodiments, the rib structures 320 may form other grid shapes. Referring to fig. 3 again, the surface of each rib structure 320 near the striking surface 212 has different slopes, and the gradual slope design of the rib structure 320 mainly provides the force for dissipating the external force and generating resilience when the golf club head cover 300 is impacted by the external force. In one embodiment, the slope of the rib structure (e.g., rib structure 321) closer to the ball striking surface 212 is more gradual than the slope of the rib structures (e.g., rib structures 322 and 323) farther from the ball striking surface 212. Therefore, when the golf head cover 300 is impacted by external force and extruded and deformed, the golf head cover can rebound rapidly.

Referring to fig. 2 to 4, fig. 4 is an exploded view illustrating a material structure of a golf club head cover according to an embodiment of the present disclosure. In this embodiment, the non-metal top cover body 310 is a layer structure formed by laminating the appearance layer 310a and a plurality of unidirectional fiber layers (for example, the first direction fiber layer 310b and the second direction fiber layer 310c), or the non-metal top cover body 310 is made of thermoplastic fiber reinforced composite materials such as polypropylene (PP), polyvinyl chloride (PVC), Polycarbonate (PC), polyamide resin (PA), polyether ether ketone (PEEK), Thermoplastic Polyimide (TPI), Polyphenylene Sulfide (PPs), and the like. In a specific forming manner, the appearance layer 310a may be a woven carbon fiber prepreg layer, the fiber direction of the first direction fiber layer 310b is a 90-degree direction carbon fiber prepreg layer with the extending direction perpendicular to the normal direction of the striking face 212, and the fiber direction of the second direction fiber layer 310c is a 0-degree direction carbon fiber prepreg layer with the extending direction parallel to the normal direction of the striking face 212. The first direction fiber layers 310b and the second direction fiber layers 310c are alternately stacked, and one of the first direction fiber layers 310b is adjacent to the appearance layer 310 a. For the inventor, the normal direction of the striking surface 212 refers to the extending direction perpendicular to the normal of the striking surface 212. In other examples, the normal direction may also refer to an extension direction of an imaginary line perpendicular to the striking surface 212 and passing through the center of gravity of the entire golf club head 100.

After the design layer 310a, the first direction fiber layer 310b and the second direction fiber layer 310c are stacked to form a material structure, they are pressed together into a mold and heated to form an integrated structure. The mold has a groove corresponding to the rib structure 320, so that the rib structure 320 can be formed on the inner surface 312 of the non-metal top cap body 310 when the material structure is hot pressed. Therefore, the golf club head cover 300 can be formed into a structure with thin thickness, light weight and good structural strength. In one embodiment, the bead structure 320 is formed by two unidirectional fiber layers closest to the inner surface 312 of the non-metallic header body 310. In some examples, the hot pressing of the material structure may be performed by preheating the mold to 35 degrees and then continuing to heat to 140 degrees for 30 minutes.

In the present disclosure, the golf club head cover may also have different structural designs. Referring to fig. 5, a partial cross-sectional view of a golf club head cover according to another embodiment of the present disclosure is shown. The golf head cover 400 of the embodiment shown in fig. 5 also includes a non-metallic cover body 410 and a plurality of rib structures 420. The structure of the non-metallic header body 410 shown in fig. 5 is substantially the same as the structure of the non-metallic header body 310 shown in fig. 2 and 3, except that the non-metallic header body 410 shown in fig. 5 further includes a metal sheet structure 430. In the embodiment, the metal sheet structure 430 is mainly used to reinforce the structural strength of the non-metal cap body 410, so as to make the non-metal cap body 410 thinner. In some examples, the metal sheet structure 430 may be a sheet or a mesh with a mesh structure formed by etching. As shown in fig. 5, the non-metallic header body 410 also has an outer surface 411 and an inner surface 412 opposite the outer surface 411. The rib structure 420 is disposed on the inner surface 412 of the non-metal top cap body 410, and the design principle of the rib structure 420 is the same as the design principle of the rib structure 320 of the foregoing embodiment, and therefore, the detailed description thereof is omitted.

Referring to fig. 6, an exploded view of a material structure of a golf club head cover according to another embodiment of the present disclosure is shown. In the present embodiment, the non-metal top cover body 410 is a shell structure formed by laminating a design layer 410a, a plurality of unidirectional fiber layers (e.g., a first direction fiber layer 410b and a second direction fiber layer 410c), and at least one metal sheet structure 430. In one embodiment, the appearance layer 410a may be a woven carbon fiber prepreg layer, the first direction fiber layer 410b is a 90-degree carbon fiber prepreg layer extending in a direction perpendicular to the normal direction of the striking face 212 shown in fig. 1, the second direction fiber layer 410c is a 0-degree carbon fiber prepreg layer extending in a direction parallel to the normal direction of the striking face 212, and one of the first direction fiber layers 410b is adjacent to the appearance layer 410 a. The first direction fiber layers 410b and the second direction fiber layers 410c are stacked in a staggered manner, and the arrangement positions and the number of the metal sheet structures 430 can be set according to requirements. In the example of fig. 6, the number of the metal sheet structures 430 is 2, and are disposed below the first-direction fiber layer 410b of the first layer and above the first-direction fiber layer 410b of the last layer, respectively.

After the appearance layer 410a, the first-direction fiber layers 410b, the second-direction fiber layers 410c, and the metal sheet structure 430 are stacked to form a material structure, they are pressed together into a mold and heated to form an integrated structure. The mold has a groove corresponding to the rib structure 420, so that the rib structure 420 can be formed on the inner surface 412 of the non-metal top cap body 410 when the material structure is hot-pressed. Therefore, the metal sheet structure 430 can be used as an internal reinforcing structure of the non-metal top cap body 410, so that the overall thickness of the non-metal top cap body 410 can be made thinner, for example, the thickness can be as thin as 0.35 mm. In one embodiment, as shown in fig. 5 and 6, the metal sheet structure 430 is located in a portion of the non-metal cap body 410 near the striking surface, and the rib structure 420 is not located on the corresponding inner surface 412 of the portion. That is, the portion of the non-metal cap body 410 near the striking face can be reinforced by the metal sheet structure 430, and the rest portion can be reinforced by the rib structure 420. In some examples, the mesh shape of the sheet metal structure 430 may be the same as the rib structure 420 to provide structural engagement and also to dampen shock waves generated when the ball is struck from the striking face. In order to test the strength of the golf club head cover 400 according to the present embodiment, after the golf club head cover 400 is mounted to a general club head body, a shot test of a ball speed of 55m/s is performed on the striking surface of the club head body, and after 3000 shots of the test, the golf club head cover 400 can still pass a flaw detection test. This means that the golf head cover 400 has advantages of both thin thickness and high strength.

In other embodiments, the metal sheet structure 430 may also be disposed between the appearance layer 410a and the first direction fiber layer 410b adjacent to the appearance layer 410 a. When the woven fabric or the housing with the hollow structure is used as the appearance layer 410a, the metal sheet structure 430 can expose the appearance layer 410a, so that the appearance layer 410a has a composite visual effect with metal and woven texture. In addition, by changing the arrangement position and number of the metal sheet structure 430, the appearance of the golf club head cover 400 can be changed, and the hitting audio performance can also be changed.

In view of the above, the height and shape of the rib structure of the golf club head cover of the present disclosure vary with the distance from the striking surface, so as to thin the thickness of the golf club head cover and increase the strength thereof, thereby enabling the golf club head cover to bear different striking forces and providing resilience. On the other hand, the metal sheet structure and the convex rib structure can be added into the golf head top cover to jointly reinforce the structural strength of the whole nonmetal top cover body, so that the golf head top cover is thinner, and the hitting sound frequency can be improved.
