The smart module 32 in the installation space 310 and a support frame 33 disposed in the accommodation space 310 and for the smart module 32 to pass through.

The housing 31 has a base wall 311, a surrounding wall 312 bent and extended around the base wall 311, and an outer portion formed on the outer side of the surrounding wall 312 and for screwing with the internal thread 23 of the ball head unit 2. Thread 314.

2, 3 and 4, the smart module 32 has a circuit board 321, two charging electrodes 322 disposed on the circuit board 321, and a capacitor 323 electrically connected to the circuit board 321 and the charging electrodes 322. . The charging electrodes 322 are suitable for connecting to a charging device (not shown), and the power input from the self-charging device is stored in the capacitor 323 for use.

As shown in FIGS. 2 and 4, the circuit board 321 has an acceleration gauge 3211, a gyroscope 3212, and a wireless transmission unit 3213.

The acceleration gauge 3211 is used to sense the acceleration generated when the striking surface 24 strikes the sphere 5 and convert it into a set of acceleration signals. In this embodiment, the acceleration gauge 3211 is, for example, a three-axis acceleration gauge, and the set of acceleration signals includes an x-direction acceleration signal, a y-direction acceleration signal, and a z-direction corresponding to the three coordinate axes of the three-dimensional orthogonal coordinate system, respectively.

As shown in FIG. 3, in this embodiment, the support frame 33 has a ring plate portion 330 surrounding a through hole 309, a first extension portion 331 extending away from one side of the ring plate portion 330, and a The second extending portion 332 extends away from the other side of the ring plate portion 330. The first extension portion 331 and the ring plate portion 330 together define a first area 301 for the circuit board 321 to be provided, and the second extension portion 332 and the ring plate portion 330 together define a capacitor 323 to be provided. Of the second area 302. When the smart module 32 is placed on the support frame 33, the circuit board 321 near the capacitor 323 is positioned on one side of the ring plate portion 330 away from the capacitor 323, so that the circuit board 321 is surely disposed in the first area. In 301, the capacitor 323 can also be disposed in the second region 302 after passing through the through hole 309. Since the supporting frame 33 is disposed in the accommodation space 310, it is in close contact with the inside of the surrounding wall 312 of the housing 31, so that the smart module 32 can be fixed relative to the accommodation space 310 in the accommodation space 310. The position of the casing 31 can ensure the distance between the smart module 32 and the casing 31.

In addition, since the embedded device 3 itself has a weight, when it is mounted on the ball head 2, a counterweight effect can be achieved. When adjusting the weight of the embedded device 3, it can be achieved by changing the weight and material of the support frame 33, and even placing weights (not shown) in the accommodation space 310. Since the technical characteristics of weight adjustment are conventional techniques in the related field, they will not be repeated here.

In summary, the present invention divides the hitting surface 24 of the golf club head into these hitting areas 241 to 247 each having a unique hitting area number, and senses the acceleration with the acceleration gauge 3211 and the sensing with the gyroscope 3212. Measure the angular velocity, and then use the mobile device to calculate the striking area number of one of the striking areas that the sphere 5 strikes when the striking surface 24 strikes the sphere 5 according to the received acceleration signals and angular velocity signals, and use data mode or graphics. The method is presented on the operation interface of the APP, which is very helpful to improve the performance of the user when playing golf or a game, so it can indeed achieve the purpose of the invention.
