Description

Golf club head

The present invention relates to a golfing implement, and more particularly to a golf club head.

At present, the golf club heads on the market are usually made of carbon fiber reinforced polymer composite (CFRP) in consideration of hardness, weight, and manufacturing level. The carbon fiber reinforced polymer composite (CFRP) is a thermosetting material (TS, Thermosetting) which is shaped after being heated, and has the characteristics of high hardness, light weight, and easy molding. However, since the user is used to hit a golf ball, it is generally desirable to produce a loud sound at the moment of hitting the ball, in addition to improving the sense of pressure during exercise, and also creating a psychological sense of accomplishment in conjunction with hearing. However, a golf club head made of carbon fiber reinforced polymer composite (CFRP) generally produces a muffled sound when hitting a ball, and cannot produce a loud hitting sound like a metal material.

Accordingly, it is an object of the present invention to provide a golf club head that combines strength and weight with a loud sound.

Thus, the golf club head of the present invention comprises a body and a panel unit secured to the body.

The body defines a hollow space to define an inner space, and includes a striking portion for striking, and at least one mounting portion integrally connected to the striking portion and defining a through slot communicating with the inner space .

The panel unit includes at least one sealing member made of carbon fiber reinforced thermoplastic resin (CFRTP) and mounted to the at least one mounting portion to close the through groove.

The effect of the present invention is that the carbon fiber material can achieve high strength and light weight, and the sealing member is made of carbon fiber reinforced thermoplastic resin (CFRTP) and is mounted on a mounting portion having a through groove communicating with the inner space. At the same time, it can also achieve the purpose of sounding the ball.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figure 1, a first embodiment of a golf club head of the present invention includes a body 1 and a panel unit 2 secured to the body 1.

The body 1 defines a hollow space to define an inner space 100, and includes a striking portion 11 for striking, and an integral connection to the striking portion 11 and defining a communication with the inner space 100. The mounting portion 12 of the slot 120. Wherein, the through groove 120 is upward.

The panel unit 2 includes a carbon fiber reinforced thermoplastic resin (CFRTP), and is mounted on the mounting portion 12 to close the sealing member 21 of the through groove 120, that is, the sealing member 21 is oriented upward. A top cover of the golf club head is formed. Wherein, the thickness of the sealing member 21 is 0.55 to 0.75 mm, and the carbon fiber reinforced thermoplastic resin (CFRTP) contains polyphenylene sulfide (PPS) or polycarbonate (PC). In addition, all of the carbon fibers in the carbon fiber reinforced thermoplastic resin (CFRTP) are extended in the same direction (UD), thereby strengthening the structural strength in a specific direction, and each bundle of carbon fibers is 3,000 filaments (3K). The purpose is also to strengthen the structural strength of the single bundle of carbon fibers by a sufficient number of filaments, so that the closure member 21 has a high strength at the time of hitting the ball.

Referring to FIG. 2 and in conjunction with FIG. 1, in order to surely explain the effect of the sound of the hitting sound produced by the first embodiment, the first embodiment will be used to hit the golf ball with a thickness of 0.65 mm. The sound information generated after the ball is plotted as the curve with the vertical axis as the sound intensity (decibel, dB) and the horizontal axis as the frequency (Hertz, Hz). As can be seen from FIG. 2, in the first embodiment, the sound generated during the shot is three peaks exceeding 4000 Hz, and the sound intensity exceeds the peak value of 60 decibels (4118.3, 4256.8, 4294.1), and is converted into time. Then the intensity of the sound lasts for nearly 0.5 seconds. When the sound having a intensity exceeding 60 decibels and a frequency exceeding 4000 Hz is a standard for the human ear to clearly recognize a sufficiently loud sound in the course environment, the distribution of the sound information presented by the golf ball by the first embodiment is It does produce a loud sound that can be clearly heard in the stadium environment.

2 to FIG. 4, in order to further illustrate the efficacy of the first embodiment, FIG. 3 shows a golf ball made of carbon fiber reinforced polymer composite (CFRP) under the same striking conditions as in FIG. The measurement result of the club head; and as shown in FIG. 4, the measurement result of the golf club head made of the all titanium material under the same striking condition as in FIG. Comparing Fig. 2 with Fig. 3, it can be seen that the golf club head made of carbon fiber reinforced polymer composite (CFRP) only produces a peak exceeding 60 decibels and a frequency higher than 4000 Hz, and the others exceeding 60 decibel peaks. It is distributed at a relatively low frequency between 500 and 2000 Hz, so it is significantly worse in the performance of the hitting sound. Comparing Fig. 2 with Fig. 4, it can be seen that the golf club head made of all titanium material also has a plurality of peaks exceeding 60 decibels and having a frequency higher than 4000 Hz, that is, the first embodiment is hitting the ball. The performance of the sound can indeed achieve the effect of a golf club head made of titanium.

Referring to FIG. 5, a second embodiment of a golf club head according to the present invention is different from the first embodiment in that the through groove 120 is opposite to the striking portion 11, and That is, the sealing member 21 of the panel unit 2 is a backing plate forming a golf club head. Compared with the first embodiment, the second embodiment only forms the backboard of the golf club head to meet the different product requirements, since the sealing member 21 is also made of carbon fiber reinforced thermoplastic. The resin (CFRTP) is formed, and the through groove 120 is also connected to the inner space 100, so that the same effect as the first embodiment can be achieved in the performance of the hitting sound.

Referring to FIG. 6, a third embodiment of a golf club head according to the present invention is different from the first embodiment in that the through slot 120 is facing downward, that is, the panel unit 2 The cover member 21 is a bottom plate forming a golf club head. Compared with the first embodiment, the third embodiment is only that the sealing member 21 forms the bottom plate of the golf club head to meet different product requirements, since the sealing member 21 is also made of carbon fiber reinforced thermoplastic resin. (CFRTP) is formed, and the through groove 120 is also connected to the inner space 100. Therefore, the same effect as that of the first embodiment can be achieved in the performance of the hitting sound.

Referring to FIG. 7 again, a fourth embodiment of the golf club head according to the present invention is different from the first embodiment in that the body 1 includes two mounting portions each defining a through slot 120. 12, one of the through slots 120 is facing upward, the other is facing downward, and the panel unit 2 includes two sealing members 21 respectively mounted on the mounting portions 12. That is, the sealing members 21 form the top and bottom plates of the golf club head, respectively. Since the sealing members 21 are also made of carbon fiber reinforced thermoplastic resin (CFRTP), and the through grooves 120 are connected to the inner space 100, a loud blow can also be produced in the performance of the hitting sound. The sound of the ball.

In summary, the golf club head of the present invention can be selected through the material selection and thickness adjustment of the sealing member 21, and the design of the through groove 120 of the mounting portion 12 to communicate with the inner space 100 of the body can be When the ball is hit, the same sound performance as the all-metal material is produced, and the demand for high strength and light weight is taken into consideration, so that the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
