A segmented gap 21B is further formed between any two ball striking response portions 21A, and the size of the segmented gap 21B depends on the arrangement of any two ball striking response portions 21A.
Therefore, the core 21 is easy to deform by combining the striking response portions 21A and the segmented gaps 21B between the striking response portions 21A, wherein the deformation is from Stiffness reduction (Stiffness), deflection increase (Deflection), buckling increase (Flexion), and coefficient of restitution (Coefficient of Restitution, COR), so as to facilitate controlling the time that the picoball stays in the plate 20 and also facilitate controlling the rotational force of the plate 20 to the picoball.
When the number of the segment gaps 21B is 2 or more, the molding directions of any segment gap 21B are selected from one or a combination of intersecting and non-intersecting, and the molding directions are referred to by arrow directions X in the drawing.
Each ball striking response portion 21A is further provided with a plurality of members 21A1 that are deformed in a polygonal columnar shape, a cylindrical shape, a semi-cylindrical shape, an arcuate columnar shape, or a columnar shape as described above, the members 21A1 having a first response parameter that is stiffness, but is not limited to stiffness (e.g., one or a combination of deflection, buckling, and restitution coefficients related to stiffness). The components 21A1 are arranged, and any component 21A1 extends between a corresponding rim of the frame 22, wherein the components 21A1 are arranged longitudinally with respect to each other, or the components are arranged transversely with respect to each other, or the components are arranged obliquely with respect to each other, but not limited to the above-described longitudinal arrangement, transverse arrangement, oblique arrangement, or any combination thereof.
The two components 21A1 further have a component gap 21A2 therebetween, and the size of the component gap 21A2 depends on the arrangement of the two components 21A1.
Each component 21A1 is made of one selected from the group consisting of a honeycomb structure (Honeycomb structure) and a Rib structure (Rib structure), but not limited thereto, wherein the honeycomb structure is shown in fig. 1 of US20180104555A1, and the Rib structure is shown in fig. 7 of US10377093B2, which is incorporated by reference, and the above patent is not intended to limit the component 21A1. In addition, each component 21A1 is made of one selected from carbon fiber material, hard plastic material and hard foaming material, but not limited thereto.
The frame 22 has a second response parameter, which is stiffness, but is not limited to stiffness (e.g., stiffness-related deflection, buckling, and coefficient of restitution, or a combination thereof). The frame 22 is made of one selected from Polyethylene (PE) and ethylene-vinyl acetate copolymer (Ethylene Vinyl Acetate, EVA), but not limited thereto.
Thus, the first response parameter of the component 21A1 and the second response parameter of the frame 22 are different from each other, and further different materials are made into different rigidities, and the present utility model uses the embodiment in which the first response parameter of the component 21A1 is greater than the second response parameter of the frame 22, that is, uses the embodiment in which the rigidity of the component 21A1 is greater than the rigidity of the frame 22, but is not limited to the above disclosed embodiment.
