DETAILED DESCRIPTION

(6) Referring to FIG. 2, an embodiment of a gold club head of the present disclosure includes a head unit 2 and an insertion unit 3. The head unit 2 of the gold club head is connected to a shaft 9 that is to be handled by a player.

(7) Referring further to FIGS. 3 and 4, the head unit 2 includes a main body 21, an installation hole 22 formed in the main body 21, and an internal thread 23 formed on an inner wall surface of the main body 21 and defining the installation hole 22. As shown in FIG. 2, the installation hole 22 is formed in a bottom surface of the gold club head facing away from the shaft 9. However, the location of the installation hole 22 may be changed according to practical requirements.

(8) The insertion unit 3 includes a housing body 31, an intelligent unit 32, a holding unit 33 and an encapsulant 39. The housing body 31 defines a receiving space 310 having an opening 300, and has a base wall 311, a surrounding wall 312 extending from a periphery of the base wall 311, an external thread 314 formed in an outer surface of the surrounding wall 312 for threadedly engaging the internal thread 23 of the head unit 2 so that the insertion unit 3 is detachably received in the installation hole 22, and a recess 313 (see FIG. 4) formed in the base wall 311 and adapted to permit a tool (not shown), such as a screw driver, to be engaged and rotated therein so as to rotate the housing body 31 relative to the head unit 2 for mounting the insertion unit 3 to the head unit 2 or dismounting the insertion unit 3 from the head unit 2. In this embodiment, the base wall 311 of the housing body 31 has a protrusion portion 319 (see FIG. 4) that extends away from the receiving space 310, and the recess 313 is formed in the protrusion portion 319.

(9) The holding unit 33 is received in the receiving space 310, and has a base plate 330 that is formed with a through hole 309 through which the intelligent unit 32 extends, a plurality of first extending portions 331 that extends from the base plate 330 in a direction away from the base wall 311, and a plurality of second extending portions 332 that extend from the base plate 330 in a direction toward the base wall 311. Any two adjacent ones of the first extending portions 331 cooperatively define a first encapsulant-receiving space 301 therebetween. Any two adjacent ones of the second extending portions 332 cooperatively define a second encapsulant-receiving space 302 therebetween. The first extending portions 331 and the base plate 330 cooperatively define a board-receiving space 303. The second extending portions 332 and the base plate 330 cooperatively define a capacitor-receiving space 304. In this embodiment, the holding unit 33 is press fitted within the surrounding wall 312 of the housing body 31 such that the holding unit 33 is fixedly received in the housing body 31.

(10) The intelligent unit 32 is received in the receiving space 310, extends through the holding unit 33, and includes a first circuit board 321, a second circuit board 321′, two charging electrodes 322 and a capacitor 323. The first circuit board 321 is disposed in the opening 300 of the receiving space 310, and is received in the board-receiving space 303. The second circuit board 321′ is spaced apart from the first circuit board 321 and is received in the board-receiving space 303. The charging electrodes 322 are disposed on a side surface of the first circuit board 321 facing away from the second circuit board 321′. In certain embodiments, other measuring elements (not shown) may be provided on the first circuit board 321 for measuring various data of the golf club head and a golf ball (not shown) hit by the golf club head. The capacitor 323 is received in the capacitor-receiving space 304, and is electrically connected to the first circuit board 321 and the second circuit board 321′. When the insertion unit 3 is disassembled from the head unit 2, the charging electrodes 322 may be electrically connected to an external power source (not shown) for providing electrical power to the capacitor 323 such that the electrical power is received in the capacitor 323.

(11) The encapsulant 39 is received in the receiving space 310, at least partially covers the first circuit board 321 of the intelligent unit 32, and fixes the intelligent unit 32 in the receiving space 310. The charging electrodes 322 are exposed from the encapsulant 39. In this embodiment, a portion of the encapsulant 39 is filled in the first encapsulant-receiving spaces 301 defined by the first extending portions 331. Another portion of the encapsulant 39 is filled in the second encapsulant-receiving spaces 302 defined by the second extending portions 332.

(12) The holding unit 33 ensures that there is a gap between the housing body 31 and the intelligent unit 32, and the encapsulant 39 can therefore fill up the gap for encapsulating and fixing the intelligent unit 32.

(13) The insertion unit 3 provides a counterweight to the head unit 2. The weight of the insertion unit 3 may be adjusted by changing the material of the holding unit 33, changing the density of the encapsulant 39, or placing additional counterweight members (not shown) in the receiving space 310.

(14) In order to test the durability of the golf club head of this disclosure, the golf club head was tested by hitting the golf ball at a speed of 46 meters per second. The results show that the golf club head of this disclosure is capable of withstanding more than 3000 hits with the intelligent unit 32 still functioning.

(15) In summary, the insertion unit 3 of this disclosure can be easily mounted to or dismounted from the head unit 2, and can be changed according to practical requirements. The intelligent unit 32 may be changed for measuring various data of the golf club head of this disclosure and the golf ball hit by the golf club head. The holding unit 33 and the encapsulant 39 may be changed for adjusting weight of the insertion unit 3 according to practical requirements.
