[0042] The following is a detailed description of the technical means used by the present invention to achieve the intended purpose of the invention with reference to the accompanying drawings and the embodiments of the present invention.

[0043] like Figure 1 and Figure 2 As shown, it discloses an embodiment of a golf club head made of carbon fiber material of the present invention. The golf club head can be a driver wood, a fairway wood or a general wood club, etc. The golf club head includes a club head body 1.

[0044] like Figures 1 to 6 As shown, the club head body 1 includes an integrally formed front section of the club head 10 and an integrally formed rear section of the club head 20. One or both of the front section of the club head 10 and the rear section of the club head 20 are hollow components formed by laminating thermosetting carbon fiber prepreg in a mold and curing by hot pressing. In one embodiment, the front section of the club head 10 is made of thermosetting carbon fiber prepreg by hot pressing curing, and the rear section of the club head 20 can be made of thermoplastic polymer. The front section of the club head 10 is a body with an opening facing backwards. The front section of the club head 10 has a front section base 11. The front end of the front section of the club head 11 forms a ball striking panel 12. The thickness of the ball striking panel is 1.0 mm to 6.0 mm. In one embodiment, the surface of the ball striking panel 12 has a plurality of integrally formed grooves. And a handle 13 protruding upward is formed on one side of the front end of the front section of the club head 10. The rear end of the club head 20 is formed into a body with an opening facing forward, and the front end of the rear end of the club head 20 is relatively fitted and bonded to the rear end of the front end of the club head 10, wherein the top and bottom thicknesses of the rear end of the club head 20 are designed to be uneven, and the thickness is 0.2mm to 5.0mm. A connecting assembly 40 can be installed in the handle 13, and a club rod can be assembled through the connecting assembly 40.

[0045] like Figures 1 to 6As shown, in this embodiment, the rear end periphery of the front section base 11 of the club head forms a fitting portion 14 that protrudes backwards, and the outer surface of the fitting portion 14 is lower than the outer surface of the front section base 11 of the club head and has a height difference, and the front end of the rear section component 20 of the club head can be correspondingly fitted on the outer side of the fitting portion 14 at the rear end of the front section base 11 of the club head and bonded and consolidated as one. The height difference between the outer surface of the fitting portion 14 and the outer surface of the front section base 11 of the club head matches the thickness of the front end periphery of the rear section component 20 of the club head, so that after the front end of the rear section component 20 of the club head is relatively combined with the rear end of the front section component 10 of the club head, the front end of the rear section component 20 of the club head is nearly flush with the rear end of the front section component 10 of the club head. In addition, the engaging portion 14 formed at the rear end of the front section component 10 can also be changed to be set at the front end of the rear section component 20, so that the rear end of the front section base 11 of the front section component 10 can be correspondingly sleeved on the outside of the engaging portion 14 at the front end of the rear section component 20 and bonded and fixed together.

[0046] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, at least one assembly groove 15, 21, 22 is formed in the bottom of the aforementioned front section component 10, the bottom of the rear section component 20 and / or the rear end of the rear section component 20, and one or more weight assemblies 30 are selected from the assembly grooves 15, 21, 22 to be installed. The weight assemblies 30 are designed to adopt the same or different weight combinations based on the product requirements of the golf club and the setting of the center of gravity position of the club head, and the weight assemblies 30 are installed in the assembly grooves 15, 21, 22 at appropriate positions of the club head body 1.

[0047] In this embodiment, the bottom of the front section of the club head, both sides of the bottom of the rear section of the club head 20 and the rear end of the rear section of the club head 20 are each provided with an assembly groove 15, 21, 22, and the counterweight component 30 is selectively installed in a plurality of the assembly grooves 15, 21, 22, and the counterweight component 30 can be arbitrarily interchangeably installed in the assembly grooves 15, 21, 22, and the weight of the counterweight component is not less than 20g.

[0048] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the assembly grooves 15, 21, 22 form non-circular grooves, for example: polygons such as rectangles, or long strips with pointed or arc-shaped ends, but are not limited to the aforementioned shapes. A fixing hole is provided in the inner bottom of the assembly grooves 15, 21, 22. The counterweight assembly 30 includes a counterweight block 31 and a fixing element 32. The counterweight block 31 is a component made of a metal material with a specific gravity greater than that of a carbon fiber material, such as a block made of tungsten metal material or other materials.

[0049] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the shape of the counterweight 31 matches the shape of the assembly grooves 15, 21, 22, so that the counterweight 31 can be easily aligned and installed in the assembly grooves 15, 21, 22. The counterweight 31 is provided with a through hole corresponding to the fixing hole, wherein the fixing element 32 can be a screw, and the fixing hole is a corresponding screw hole. The fixing element 32 passes through the through hole of the counterweight 31 and is fixed in the fixing hole in the assembly grooves 15, 21, 22, so that the counterweight 31 is fixed in the assembly grooves 15, 21, 22 of the club head body 1. At the same time, the counterweight 31 is non-circular in shape, so that the counterweight 31 can be positioned in the assembly grooves 15, 21, 22 without rotating.

[0050] As can be seen from the above description, the golf club head made of carbon fiber material of the present invention is constructed through the above-mentioned overall composition. The main body of the club head includes a front section 10 and a rear section 20 integrally formed with carbon fiber material. The front section 10 is integrally formed with a striking panel 12 and a handle 13 on one side thereof at the front end of the front section base 11 of the club head. Therefore, the three-dimensional spatial shapes of the front section 10 and the rear section 20 are properly divided and designed, and the front section base 11 of the front section 10 is appropriately extended and lengthened so that the length of the rear section 20 can be appropriately reduced, and the front section 10 and the rear section 20 can be effectively adjusted to be within an appropriate length range, which helps the front section 10 and the rear section 20 to be automatically matched with a mold for carbon fiber prepreg lamination and hot pressing curing process, and the front section 10 and the rear section 20 can be relatively embedded and consolidated into one, which helps the automated production of golf club heads made of carbon fiber material.

[0051] At the same time, the front section component 10 of the club head formed of the carbon fiber material is formed with a striking panel 12 and a club handle 13 on one side thereof integrally formed at the front end of the front section component 10, so that the striking panel 12 is firmly combined with the base of the front section of the club head, thereby enhancing the mechanical strength of the striking panel 12 at the front end of the club head body 1, so that the striking panel 12 will not fall off after multiple hitting of the ball.
