Detailed Description

The invention is described in detail below with reference to the following figures and examples:

referring to fig. 1 and 2, a first embodiment of a striking plate of a golf club head according to the present invention is shown, in which the golf club head 1 includes a shell 2 and a striking plate 3 combined with the shell 2 and cooperating with each other to define a space 21. The striking plate 3 includes a plate 31 and a rib 32 located in the space 21 and having both ends connected to the plate 31. Defining a first direction a through said plate 31, said plate 31 being substantially flat and extending along a second direction B perpendicular to said first direction a, and a third direction C perpendicular to said first direction a and said second direction B, and the length of said plate 31 in said second direction B being smaller than the length in said 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 edges 321 integrally connected to the outer edge 312 of the plate 31 at intervals along the second direction B, and a connecting portion 322 extending along the second direction B and having two ends respectively connected to the end edges 321. The connecting portion 322 is spaced from the plate 31 along the first direction a and has an arc shape.

Referring to fig. 1, 2, and 3, when a plate 31 of the striking plate 3 impacts a sphere 4, the plate 31 slightly bends due to its elasticity as shown in fig. 3, and the rib 32 forms bending moment at two ends and is bent due to the deformation of the plate 31, so that the rib 32 accumulates elastic force like a spring, the plate 31 and the rib 32 recover and release the elastic force, and finally the sphere 4 is struck out, so that the first embodiment can effectively absorb impact and convert the impact into kinetic energy by the assistance of the rib 32 of the bridge structure, and finally reflects the impact energy with a high elastic Coefficient value (referred to as "COR value") and can reduce the Characteristic Time (referred to as "CT value") of impacting the sphere 4. Meanwhile, the two ends of the rib 32 are connected to the plate 31, which not only can generate the spring effect to improve the value of the elasticity coefficient, but also can provide a supporting force to increase the durability and the overall strength of the plate 31, thereby overcoming the long-standing problems in the art. In addition, since the strength can be maintained by the ribs 32, the plate 31 can be thinned as needed to distribute the weight to different portions of the golf club head 1, so that the designer can adjust different characteristics of the balance, stability and distance of the hitting ball by the weight configuration, thereby greatly improving the configuration flexibility.

Referring to fig. 1, 4 and 5, the maximum distance between the rib 32 and the plate 31 in the first direction a is generally controlled to be between 4mm and 8mm, preferably 8mm, but may be adjusted according to the actual size of the plate 31. The end edge 321 may extend straight in the first direction a as shown in fig. 4 to have a straight column shape. Alternatively, the outer diameter of the rib 32 may gradually decrease from the two ends to the center (i.e., from the end edge 321 to the connecting portion 322) as shown in fig. 5, and in addition to the above-mentioned variation, a designer may also adjust the length of the rib 32 or the deflection of the rib 32 to achieve different design purposes or improve the sound performance of the striking plate 3 when striking a ball, which should not be limited to the state disclosed in the first embodiment.

Referring to fig. 6, a second embodiment of the striking plate of the golf club head of the present invention is substantially the same as the first embodiment, except that: the end edge portions 321 of the rib 32 of the second embodiment are spaced from each other along the third direction C, and the connecting portion 322 extends along the third direction C. By arranging the ribs 32 in the longer direction of the plate 31, the hitting sound and decibels can be improved, thereby creating different hitting sounds and increasing the selectivity of designers and consumers.

Referring to fig. 7, a third embodiment of the striking plate of the golf club head of the present invention is substantially the same as the first embodiment, except that: the third embodiment includes two ribs 32 extending along the second direction B and the third direction C respectively and being staggered or connected to each other, the third embodiment can further improve the structural strength, and the number of the ribs 32 may also be more than two, which is not limited to this.

Referring to fig. 8, a fourth embodiment of the striking plate of the golf club head of the present invention is substantially the same as the first embodiment, except that: the plate 31 is curved, and the rib 32 extends along the second direction B to form a straight bar, and is spaced from the rib 32 in the first direction a by the concave folding of the plate 31. The fourth embodiment can be applied to the non-flat plate-shaped plate body 31, and provides another choice for designers, thereby effectively improving the universality.

The following are experimental examples of the present invention:

referring to fig. 1, 4 to 6, in this experimental example, nine sets of golf club heads 1 having different striking plates 3 were subjected to stress simulation, respectively, wherein the 1 st set was a control set, which was a conventional golf club head not provided with the rib 32 of the present invention, and the 2 nd-1 nd and 2 nd-2 nd sets were the basic states shown in fig. 1 of the first embodiment, that is, the rib 32 extended in the second direction B, and the rib 32 was curved in an arc shape as a whole and had the same outer diameter. Groups 3-1 and 3-2 are variations of the first embodiment, and as shown in fig. 4, the end edge portions 321 of the ribs 32 are straight and cylindrical without being bent, and the outer diameter of the end edge portions 321 is different from that of the connecting portions 322, and each end edge portion 321 extends along the first direction a by a length of 2 mm. Group 4 is another variation of the first embodiment, and the outer diameter of the rib 32 is gradually reduced from the end edge 321 to the connecting portion 322 as shown in fig. 5. Groups 5-1 and 5-2 are substantially similar to groups 2-1 and 2-2, except that the maximum spacing of the ribs 32 from the plate 31 in the first direction A is greater (i.e., the maximum spacing indicated in Table one). Group 6 is the state shown in fig. 6 of the second embodiment, i.e. the ribs 32 extend in the third direction C.

Watch I,

As can be seen, the golf club head 1 with the ribs 32 has better striking face stress performance than the conventional golf club head without the ribs 32, wherein the 5 th-1 st group, the 5 th-2 nd group, the 2 nd-1 st group and the 2 nd-2 nd group can generate larger striking face stress, i.e. when the maximum distance in the first direction a is larger and when the end edge 321 is a straight line extension, the best striking face performance can be obtained.

In summary, the present invention obtains a higher value of the elastic coefficient by the spring effect of the ribs 32, and provides a high structural strength by the bridging structure, so that the present invention has both the characteristics of high elastic coefficient and high strength, and has various variations and practical applicability, thereby achieving the purpose of the present invention.
