AI Technical Summary
To increase the impact resistance or shock absorption of existing hockey sticks, through holes need to be made in the shaft, which makes the manufacturing process cumbersome and reduces the strength of the shaft.
Adding functional interlayers, including elastic material interlayers, carbon fiber interlayers, or Kevlar material layers, to the molded core of the striking bend enhances performance by layering composite materials, avoiding modifications to other parts of the shaft.
The manufacturing process was simplified, the integrity and strength of the shaft were maintained, and the impact resistance and shock absorption functions were increased.

[0022] The utility model will be further described in combination with the drawings and specific embodiments.
[0023] Embodiment one
[0024] Reference Figures 1 to 4As shown, the hockey stick provided by the embodiment is a grass hockey stick, which comprises a stick body 10 and a striking bend 20 connected to the end of the stick body 10, wherein the striking bend 20 comprises a shaped inner core 21 arranged at the innermost layer, a carbon fiber layer (not shown) wrapped outside the shaped inner core 21, and a striking shell 22 sealed outside the carbon fiber layer; the shaped inner core 21 comprises a foaming body 211 and a functional interlayer 212 clamped or wrapped in the foaming body 211; specifically, the functional interlayer 212 clamped in the foaming body 211 can be understood as that the foaming body 211 comprises a separated first foaming body and a second foaming body, and the functional interlayer 212 is clamped between the first foaming body and the second foaming body to form a sandwich structure. The functional interlayer 212 wrapped in the foaming body 211 can be understood as that the functional interlayer 212 is completely wrapped in the whole foaming body 211, such as Figure 4 As shown, that is, during preparation, the foaming material completely wraps the functional interlayer 212 to obtain the structure by foaming. In the embodiment, the functional interlayer 212 is wrapped in the foaming body 211; of course, the functional interlayer 212 can also be clamped in the foaming body 211 to form a sandwich structure.
[0025] Preferably, the functional interlayer 212 is parallel to the striking surface of the striking bend 22, so that the functional interlayer 212 can cover more area of the striking surface of the striking bend 22. Of course, due to the error in preparation, there is also a slight inclination between the functional interlayer 212 and the striking surface of the striking bend 22, which is also acceptable.
[0026] Specifically, the shape of the shaped inner core 21 is the same as or similar to the shape of the striking bend 22, except that the size of the shaped inner core 21 is proportionally reduced compared with the striking bend 22.

The functional interlayer 212 is an elastic material interlayer, which can effectively reduce the shock.
[0028] Further, in the embodiment, the striking shell 22 and the outer shell of the stick body 10 are in an integrated connection structure; and are integrally prepared by a mold.
[0029] The hockey stick provided by the embodiment only needs to prepare a corresponding shaped inner core in advance, which is simple to operate and does not need to change other parts, thereby ensuring the integrity and strength of the product shell.
