Description

Technical Field

[0001] This utility model relates to the technical field of Peak rackets, and more specifically, to Peak rackets with honeycomb core shock absorption. Background Technology

[0002] Peakball is a sport that combines features of tennis, badminton, and table tennis, and it has developed rapidly worldwide in recent years. Traditional peakball rackets are mostly made of wood, plastic, or metal, which have problems such as high weight, poor impact feedback, and insufficient shock absorption.

[0003] In existing technologies, some composite materials, such as carbon fiber and glass fiber, are used in the manufacture of Peak rackets, but most structural designs still do not fully balance lightweighting and comfort. Therefore, there is an urgent need for a new type of Peak racket structure that can reduce overall weight, effectively reduce impact vibration, and improve the player's control and comfort when hitting the ball. Utility Model Content

[0004] The purpose of this invention is to provide a honeycomb core shock-absorbing Peak racket, aiming to solve the problem of insufficient shock absorption performance of Peak rackets in the prior art.

[0005] This utility model is implemented as follows: a honeycomb core shock-absorbing Peak racket includes an inner core board made of EPP foam, the inner core board having an upward-facing upper surface and a downward-facing lower surface, and the upper and lower surfaces of the inner core board are respectively covered with an intermediate fabric layer made of glass fiber cloth.

[0006] The inner surface of the intermediate fabric layer is fused and bonded to the inner core plate by hot pressing. The outer surface of the intermediate fabric layer is covered with an outer shell plate made of carbon fiber composite material. The outer shell plate and the intermediate fabric layer are fused and bonded together by hot pressing.

[0007] The inner core plate is provided with multiple through holes, which penetrate the inner core plate vertically, and the multiple through holes are arranged in a honeycomb pattern on the horizontal plane.

[0008] Furthermore, the inner core plate, the upper and lower intermediate fabric layers, and the outer shell layer corresponding to the two intermediate fabric layers are combined to form an integrated composite structure.

[0009] Furthermore, the outer peripheral edge of the composite structure is provided with a sealing strip, which is continuously arranged circumferentially along the outer peripheral contour of the composite structure.

[0010] Furthermore, the top and bottom of the sealing strip extend laterally inward to form an outer shell segment covering the outer surface of the outer shell plate, and the outer shell segment is arranged continuously along the circumferential contour of the composite structure.

[0011] Furthermore, the inner side of the sealing strip is tightly fitted to the edges of the inner core plate, the intermediate fabric layer, and the outer shell plate layer, completely sealing the outer periphery of the composite structure.

[0012] Furthermore, the composite structure has a handle for hand gripping, the surface of which is covered with a non-slip rubber sleeve.

[0013] Furthermore, the through hole is polygonal in shape.

[0014] Furthermore, the outer peripheral edge of the inner core plate is aligned and coincides with the outer peripheral edge of the intermediate fabric layer and the outer peripheral edge of the outer shell plate layer.

[0015] Furthermore, the multiple through holes are arranged in a matrix-like uniform spacing on the inner core plate.

[0016] Furthermore, a hot melt adhesive film is formed between the inner core board and the intermediate fabric layer by melting, and the hot melt adhesive film tightly connects the inner core board and the intermediate fabric layer into one piece.

[0017] Compared to existing technologies, the honeycomb core shock-absorbing Peak racket provided by this invention features a lightweight and highly resilient EPP foam inner core, laying the foundation for overall weight reduction. Furthermore, the honeycomb arrangement with through-holes further enhances weight reduction. The fiberglass cloth middle layer not only fuses tightly with the inner core through hot pressing but also provides stable support for the outer carbon fiber shell, achieving a seamless connection between multiple materials. The carbon fiber composite shell layer ensures sufficient rigidity of the racket face, guaranteeing accurate power transmission during shots and preventing the landing point from being affected by racket face deformation. The three-layer structure is bonded together through hot pressing, eliminating loose gaps. Regardless of repeated shots or accidental impacts, it is not prone to delamination or cracking, making its durability far superior to ordinary spliced ​​rackets. Attached Figure Description

[0024] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0025] The honeycomb core shock-absorbing Peak racket provided by this utility model includes an inner core board 100 made of EPP foam. The inner core board 100 has an upper surface arranged upward and a lower surface arranged downward. The upper surface and the lower surface of the inner core board 100 are respectively covered with an intermediate cloth layer 300 made of glass fiber cloth.

[0026] The inner surface of the intermediate fabric layer 300 is fused and bonded to the inner core plate 100 by hot pressing. The outer surface of the intermediate fabric layer 300 is covered with an outer shell plate layer 400 made of carbon fiber composite material. The outer shell plate layer 400 and the intermediate fabric layer 300 are fused and bonded together by hot pressing.

[0027] The inner core plate 100 is provided with multiple through holes 101, which penetrate the inner core plate 100 vertically, and the multiple through holes 101 are arranged in a honeycomb pattern on the horizontal plane.

[0028] The aforementioned honeycomb core shock-absorbing Peak racket features a lightweight and highly resilient EPP foam inner core plate 100, laying the foundation for overall weight reduction. The honeycomb arrangement with through-holes further enhances its lightweight design. Next, the fiberglass cloth middle layer 300 not only fuses tightly with the inner core plate 100 through hot pressing but also provides stable support for the outer carbon fiber shell, achieving a seamless connection between the various materials. The carbon fiber composite outer shell layer 400 ensures sufficient rigidity of the racket face, guaranteeing accurate power transmission during shots and preventing the landing point from being affected by racket face deformation. The three layers are bonded together through hot pressing, leaving no loose gaps. Regardless of repeated shots or accidental impacts, it is not prone to delamination or cracking, making its durability far superior to ordinary spliced ​​rackets.

[0029] Specifically, the multiple through-holes 101 arranged in a multi-honeycomb pattern can disperse impact energy along a honeycomb path, absorbing vibration energy. Furthermore, the honeycomb core inner plate 100 can effectively reduce the weight of the racket while ensuring strength, making the racket swing easier.

[0030] Specifically, the inner core plate 100, the two upper and lower intermediate fabric layers 300, and the corresponding outer shell plate layer 400 outside the two intermediate fabric layers 300 are combined to form an integrated composite structure. In this way, they are bonded into a whole without loose gaps. No matter how many times you hit the ball or how many accidental collisions you experience, it is not easy for delamination or cracking to occur. Its durability is far superior to that of ordinary spliced ​​rackets.

[0031] The composite structure features a sealing strip 10 along its outer periphery, which is continuously arranged circumferentially along the outer contour. This effectively prevents water, gas, and other substances from entering the interior through the edge gaps, reducing the ingress of external dust and maintaining internal cleanliness.

[0032] The top and bottom of the sealing strip 10 extend laterally inward to form an outer shell segment 11 covering the outer surface of the outer shell panel 400. The outer shell segment 11 is continuously arranged circumferentially along the outer perimeter of the composite structure. In this way, the outer shell segment 11, covering the outer surface of the outer shell panel 400, fills more gaps and reduces the possibility of gases, liquids, and other substances entering the interior from the edges of the composite structure. When there is rain or moisture outside, the outer shell segment 11 of the sealing strip 10 can effectively block it, making it difficult for it to penetrate into the interior, thus providing good waterproofing.

[0033] Specifically, the inner side of the sealing strip 10 is tightly fitted to the edges of the inner core plate 100, the intermediate fabric layer 300, and the outer shell plate layer 400, completely sealing the outer perimeter of the composite structure. This enhances structural stability and acts as a protective ring.

[0034] The composite structure includes a handle 20 for gripping, the surface of which is covered with an anti-slip rubber sleeve 21. This improves hand grip comfort and prevents slippage.

[0035] Specifically, the through hole 101 is polygonal in shape. It can be a regular hexagon.

[0036] The outer periphery of the inner core plate 100 is aligned and overlaps with the outer periphery of the intermediate fabric layer 300 and the outer periphery of the outer shell plate layer 400. The overall structure is smooth and seamless.

[0037] Multiple through holes 101 are arranged in a matrix at uniform intervals on the inner core plate 100. In this way, the matrix arrangement allows the impact force to be evenly distributed across the entire striking surface, avoiding deformation or damage caused by local stress concentration.

[0038] In this process, a hot melt adhesive film 200 is formed between the inner core panel 100 and the intermediate fabric layer 300 by melting, which tightly connects the inner core panel 100 and the intermediate fabric layer 300 into one unit. This tight bond ensures uniform transmission of impact force.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
