Description

Technical Field

[0001] This utility model relates to the technical field of Peak rackets, and more specifically, to lightweight and shock-absorbing Peak rackets. 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 lightweight, 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 achieved as follows: a lightweight 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 fiberglass cloth.

[0006] The inner surface of the intermediate fabric layer is fused and bonded to the inner core plate by hot pressing, and 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 by hot pressing.

[0007] The inner core plate is provided with a plurality of central through holes and a plurality of peripheral through holes, which penetrate the inner core plate vertically. The middle part of the inner core plate forms a central region, and the plurality of central through holes are arranged in the central region. The plurality of peripheral through holes are arranged at intervals around the outer periphery of the central region, and the size of the peripheral through holes is larger than that of the central through holes.

[0008] Furthermore, the central through-hole is polygonal in shape; the plurality of central through-holes are arranged in a matrix-like uniform interval in the central region.

[0009] Furthermore, the peripheral through holes are elongated oval in shape; the plurality of peripheral through holes are arranged in a uniformly spaced ring around the periphery of the central region.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] Furthermore, the composite structure has a handle for hand gripping, the surface of which is covered with a non-slip rubber sleeve.

[0015] 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.

[0016] 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.

[0017] Compared to existing technologies, the lightweight shock-absorbing Peak racket provided by this invention features a lightweight yet highly resilient EPP foam inner core, laying the foundation for overall weight reduction. Furthermore, the fiberglass cloth interlayer not only fuses tightly with the inner core through heat 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 impact and preventing the ball's trajectory from being affected by racket face deformation. When the ball strikes the racket face, the elastic deformation of the EPP foam inner core quickly dissipates the vibration energy, significantly reducing the impact transmitted to the arm and minimizing muscle fatigue.

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

[0025] The lightweight 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 upward-facing upper surface and a downward-facing lower surface. 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 a plurality of central through holes 101 and a plurality of peripheral through holes 102. The central through holes 101 and peripheral through holes 102 penetrate the inner core plate 100 vertically. The central part of the inner core plate 100 forms a central region. The plurality of central through holes 101 are arranged in the central region, and the plurality of peripheral through holes 102 are arranged at intervals around the periphery of the central region. The size of the peripheral through holes 102 is larger than that of the central through holes 101.

[0028] The lightweight, shock-absorbing Peak racket described above features a lightweight yet highly resilient EPP foam inner core plate 100, laying the foundation for overall weight reduction. Next, the fiberglass cloth middle layer 300 not only fuses tightly with the inner core plate 100 through heat pressing but also provides stable support for the outer carbon fiber shell, achieving a seamless connection between multiple 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. When the ball impacts the racket face, the elastic deformation of the EPP foam inner core plate 100 quickly dissipates the shock energy, significantly reducing the vibration transmitted to the arm and minimizing muscle fatigue.

[0029] Furthermore, the design of the central through-hole 101 and the outer peripheral through-hole 102 further achieves weight reduction. The central region is equipped with high-density, small-sized central through-holes 101, while the outer periphery of the central region is equipped with larger-sized outer peripheral through-holes 102. This differentiated through-hole design enables precise control of the overall weight and optimizes the stress structure of the racket face by utilizing the distribution of through-holes in different regions.

[0030] The central area, as the main hitting zone, features small, high-density central through-holes 101 that reduce weight while minimizing the impact on racket face rigidity, ensuring hitting stability. The large peripheral through-holes 102 on the outer periphery maximize the reduction of weight in non-core areas. Combined with the characteristics of the inner core plate 100 and the outer layer material, they enhance the overall elasticity of the racket face, making power transmission smoother and further improving shock absorption and feel.

[0031] Specifically, the central through-hole 101 is polygonal; multiple central through-holes 101 are arranged in a matrix-like, evenly spaced pattern in the central region. The central through-hole 101 can be a regular octagon. The grid structure formed between adjacent central through-holes 101 further enhances the overall performance of the core hitting area of ​​the racket face. When the ball hits the center of the racket face, the impact force is quickly dispersed to the surrounding areas through the grid-like framework, avoiding excessive local deformation.

[0032] Specifically, the peripheral through-holes 102 are elongated oval in shape; multiple peripheral through-holes 102 are arranged in a uniform, circumferential pattern around the periphery of the central region. This design, where the peripheral region is a non-primary hitting area of ​​the racket face, maximizes the removal of redundant material in this area by using elongated oval through-holes, significantly reducing the weight at the edge of the racket face. This design, which maintains strength in the core area while reducing weight in the peripheral area, allows the racket face's center of gravity to be closer to the central hitting area, reducing edge inertia during the swing and making the swing more flexible and responsive, especially suitable for the high-frequency, rapid offensive and defensive transitions in peak ball sport.

[0033] 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.

[0034] In a preferred embodiment, a sealing strip 10 is provided on the outer peripheral edge of the composite structure, and the sealing strip 10 is continuously arranged circumferentially along the outer peripheral contour of the composite structure. This effectively prevents water, gas, and other substances from entering the interior through the edge gaps of the composite structure, reducing the ingress of external dust and maintaining internal cleanliness.

[0035] 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.

[0036] 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.

[0037] The composite structure has a handle 20 for hand gripping, and the surface of the handle 20 is covered with a non-slip rubber sleeve 21. This improves hand grip comfort and prevents slippage.

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

[0040] 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.
