[0038] In order to illustrate in detail the technical features of the present invention, the golf club head 10 of the present invention will be described as follows with reference to the drawings.

[0039] For the first preferred embodiment of the present invention, please refer to Figure 1 , the golf club head 10 of the present invention includes a club head body 20 and a panel 30. Among them, the material of the club head body 20 includes steel alloy and titanium alloy. In addition, the material of the panel 30 is a low-density metal with a density of 3 or less, but not limited thereto. In addition, the club head body further includes a back plate 22 with a thickness of 0.4 mm - 1.5 mm, and the panel 30 has a thickness of 1 mm - 3 mm; thereby providing a better weight balance effect and further enhancing the hitting feeling superior to that of ordinary club heads.

[0040] Please refer to Figure 2 and Figure 3 , the club head body 20 has a striking face 21, and a first friction increasing structure 23 is provided on the outer surface of the striking face 21.

[0041] The panel 30 is disposed on the hitting surface 21. In this preferred embodiment, the example of bonding with adhesive is taken (the adhesive is a commonly used technical means in the art, so it is not shown in the figure), and it covers the first friction-increasing structure 23. The surface of the panel 30 facing the hitting surface 21 is provided with a second friction-increasing structure 33, and the second friction-increasing structure 33 contacts the first friction-increasing structure 23. Thus, when the panel 30 is bonded to the hitting surface 21, the frictional force formed between the first friction-increasing structure 23 and the second friction-increasing structure 33 can effectively increase the bonding strength between the panel 30 and the hitting surface 21, and can also increase the bonding area between the panel 30 and the hitting surface 21, thereby improving the integrity rate of the golf club head 10. In actual implementation, the manner in which the panel 30 is disposed on the hitting surface 21 can also be implemented by using common connection means such as fitting and clamping according to the shapes of the first friction-increasing structure 23 and the second friction-increasing structure 33.

[0042] In this preferred embodiment, the first friction-increasing structure 23 is a plurality of concave portions 25, and they are circular. The second friction-increasing structure 33 is a plurality of convex portions 35, and they are circular. The plurality of concave portions 25 correspond to the plurality of convex portions 35, and the plurality of concave portions 25 and the plurality of convex portions 35 are arranged dispersedly. It should also be noted that due to the structural characteristics of the plurality of concave portions 25 and the plurality of convex portions 35, when using the present invention to hit a golf ball, in the case where the panel 30 contacts the golf ball, the plurality of concave portions 25 and the plurality of convex portions 35 will form a gear effect with the golf ball (that is, the plurality of convex portions 35 will further provide frictional force to the golf ball), thereby increasing the initial velocity and flight distance of the hit.

[0043] In actual implementation, the plurality of concave portions 25 and the plurality of convex portions 35 can also be set to other geometric or irregular shapes according to requirements. As long as the structural characteristics presenting the concave and convex concepts are all within the scope and implementation aspects protected by the present invention, the implementation forms of the plurality of concave portions 25 and the plurality of convex portions 35 should not be limited to this preferred embodiment only.

[0044] In actual implementation (not shown in the figure), the first friction-increasing structure 23 can also be set as a plurality of convex portions 35, the second friction-increasing structure 33 can be set as a plurality of concave portions 25, and the plurality of convex portions 35 correspond to the plurality of concave portions 25; or, the first friction-increasing structure 23 can be set to have the plurality of concave portions 25 and the plurality of convex portions 35, the second friction-increasing structure 33 can be set to have the plurality of convex portions 35 and the plurality of concave portions 25, and the plurality of concave portions 25 and the plurality of convex portions 35 on the hitting surface 21 respectively correspond to the plurality of convex portions 35 and the plurality of concave portions 25 on the panel 30. By such an implementation form, the effect of increasing the initial velocity and flight distance of the hit can also be achieved.

[0045] In this preferred embodiment, a groove 27 is recessed in the hitting surface 21. The first friction-increasing structure 23 is located in the groove 27, and the panel 30 is disposed in the groove 27, and the periphery of the panel 30 contacts the inner wall of the groove 27. Thereby, the bonding strength between the panel 30 and the hitting surface 21 can also be effectively increased, and the bonding area between the panel 30 and the hitting surface 21 can also be increased, thereby improving the service rate of the golf club head 10. In actual implementation, when the bonding strength between the panel 30 and the hitting surface 21 is already sufficient, the groove 27 may not be provided on the hitting surface 21, and the panel 30 is directly bonded to the hitting surface 21 only by the surface. Therefore, the technical feature of providing the groove 27 on the hitting surface 21 is not a necessary condition for achieving the present invention.

[0046] In summary, the structural features of the plurality of concave portions 25 and the plurality of convex portions 35 of the golf club head 10 of the present invention can effectively increase the bonding strength between the panel 30 and the hitting surface 21, and can also increase the bonding area between the panel 30 and the hitting surface 21, thereby improving the service rate of the golf club head 10.

[0047] In addition, the structural features of the plurality of concave portions 25 and the plurality of convex portions 35 of the golf club head 10 of the present invention will form a gear effect with the golf ball during hitting, thereby increasing the initial velocity and flight distance of the hit ball.

[0048] For the second preferred embodiment of the present invention, please refer to Figure 5 and Figure 6 As shown, its main technical features are generally the same as those of the foregoing first preferred embodiment, and the difference lies in:

[0049] Please refer to Figure 5 and Figure 6 As shown, the hitting surface 21' has a through hole 29'. In actual implementation, the through hole 29' can be set to various geometric shapes (circular and rhombus are taken as examples in this preferred embodiment), or irregular shapes (not shown in the figure), and the number of the through holes 29' can be increased according to requirements (the number one is taken as an example in this preferred embodiment), thereby achieving the effect of weight reduction; and if there is no such requirement, this technical feature can be omitted. Therefore, the through hole is not a necessary condition for achieving the present invention.

[0050] The remaining structures and functions of the second preferred embodiment are generally the same as those of the foregoing first preferred embodiment, so they will not be described in detail.

[0051] Of course, the present invention can also have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should all fall within the protection scope of the claims of the present invention.
