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

Referring to FIG. 1 and FIG. 2, a first embodiment of a striking panel of a golf club head according to the present invention. The golf club head 1 includes a shell seat 2 and a shell seat 2 combined with and mating with each other to define A space 21 strikes the panel 3. The striking panel 3 includes a plate body 31 and a rib 32 located in the space 21 and connected at both ends to the plate body 31. A first direction A passing through the plate body 31 is defined, the plate body 31 is substantially flat and follows a second direction B perpendicular to the first direction A, and a perpendicular direction A and the second direction B The third direction C extends, and the length of the plate body 31 in the second direction B is shorter than the length in the third direction C. The plate body 31 includes a central portion 311 and an outer edge portion 312 surrounding the central portion 311. The rib 32 includes two end portions 321 integrally connected to the outer edge portion 312 of the plate body 31 at a distance from each other along the second direction B, and an end portion 321 extending along the second direction B and connected to the two ends respectively. The connecting portion 322 of the end edge portion 321. The connecting portion 322 is spaced from the plate body 31 along the first direction A and is curved.

Referring to FIG. 1, FIG. 2, and FIG. 3, when the plate 31 of the striking panel 3 strikes a sphere 4, the plate 31 is slightly concave and curved due to its elasticity as shown in FIG. 3, and The rib 32 will also form a bending moment at both ends due to the deformation of the plate body 31 and be concavely folded, so that the rib 32 will accumulate elastic force like a spring, and then the plate body 31 and the rib 32 will return to the original state and be released. The elastic force finally hits the sphere 4 and is assisted by the ribs 32 of the bridge structure, so that the first embodiment can effectively absorb the impact and convert the impact into kinetic energy, which is finally reflected to the impact energy and has a high elastic coefficient. Coefficient of Restitution (referred to as COR value, also referred to as the return coefficient value), and can reduce the characteristic time (Characteristic Time, referred to as CT value) of hitting the sphere 4. At the same time, the two ends of the rib 32 are connected to the plate body 31. In addition to generating the aforementioned spring effect to improve the value of the elastic coefficient, it can also provide a supporting force to increase the durability and overall strength of the plate body 31, which overcomes this problem. The field has long been a problem. In addition, since the strength can be maintained through the ribs 32, the plate 31 can be thinned according to requirements to distribute the weight to different parts of the golf club head 1, so that the designer can adjust the impact of the ball through the weight configuration. Different characteristics such as balance, stability and distance greatly improve configuration flexibility.

Referring to FIG. 1, FIG. 4, and FIG. 5, the maximum distance between the rib 32 and the plate body 31 in the first direction A is generally controlled between 4 mm and 8 mm, preferably 8 mm, but of course, it can be determined according to the plate body. 31's actual size is adjusted. The edge portions 321 may extend straight in the first direction A as shown in FIG. 4 to form a straight column shape. Alternatively, the outer diameter of the rib 32 may be gradually reduced from both ends to the center as shown in FIG. 5 (that is, gradually decreased from the edge portions 321 to the connecting portion 322). In addition to the above-mentioned changes, the design You can also adjust the length of the rib 32 or the deflection of the rib 32 to respond to different The purpose of designing or improving the sound performance of the striking panel 3 when hitting a ball should not be limited to the aspect disclosed in the first embodiment.

Referring to FIG. 6, a second embodiment of a striking panel of a golf club head according to the present invention is substantially the same as the first embodiment, except that the ribs 32 of the second embodiment are different from each other. The edge portions 321 are spaced apart from each other along the third direction C, and the connecting portions 322 extend along the third direction C. By placing the rib 32 in a longer direction of the plate body 31, the sound of the ball can be increased and the number of decibels can be increased, thereby creating different sounds of the ball and increasing the selectivity of the designer and the consumer.

Referring to FIG. 7, a third embodiment of a hitting panel for a golf club head according to the present invention is substantially the same as the first embodiment, except that the third embodiment includes two separate edges. The ribs 32 extending in the second direction B and the third direction C and staggered or connected to each other, the third embodiment can further improve the structural strength, and the number of the ribs 32 can also be more than two, which is not the case. Limited.

Referring to FIG. 8, a fourth embodiment of a hitting panel for a golf club head according to the present invention is substantially the same as the first embodiment, except that the plate body 31 has a curved plate shape. The rib 32 extends in a straight shape along the second direction B, and is recessed through the plate body 31 to be spaced from the rib 32 in the first direction A. The fourth embodiment can be applied to a non-flat plate body 31, providing the designer with another option to effectively improve versatility.

The following are experimental examples of the present invention: Referring to FIG. 1, FIG. 4 to FIG. 6, in this experimental example, stress simulations are performed on nine groups of golf club heads 1 with different striking panels 3. The first group is a control group, which is not provided with the ribs of the present invention. 32 conventional golf club heads, groups 2-1 and 2-2 are the basic state shown in FIG. 1 of the first embodiment, that is, the rib 32 extends along the second direction B, and the rib 32 as a whole is curved and has the same outer diameter. Groups 3-1 and 3-2 are a variation of the first embodiment. As shown in FIG. 4, the end edges 321 of the rib 32 are straight columns without bending, and the ends The outer diameter of the edge portion 321 is different from that of the connecting portion 322, and the length of each end edge portion 321 extending in the first direction A is 2 mm. The fourth group is another variation of the first embodiment. As shown in FIG. 5, the outer diameter of the rib 32 gradually decreases from the edge portions 321 toward the connecting portion 322. Groups 5-1 and 5-2 are roughly similar to groups 2-1 and 2-2, except that the maximum distance between the ribs 32 along the first direction A to the plate 31 is larger (that is, (Maximum spacing referred to in Table 1). The sixth group is the aspect shown in FIG. 6 of the second embodiment, that is, the rib 32 extends along the third direction C.

As can be seen from Table 1, the golf club head 1 with the ribs 32 has a better performance than the conventional golf club heads without the ribs 32. Groups 5-1, Group 5-2 can generate large ball striking surface stress, that is, when the maximum distance in the first direction A is large, and when the end edge portions 321 extend in a straight line segment, the best Strike performance.

In summary, the present invention obtains a higher elastic coefficient value through the spring effect of the rib 32, and provides high structural strength through the bridge structure, so it has both the characteristics of high elastic coefficient value and high strength, and there are multiple variations Because it is practical, it can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
