Description

Technical Field

[0001] This utility model relates to the field of Peak rackets, specifically to a cold-pressed reinforced Peak racket. Background Technology

[0002] Pickleball is a racket sport that combines features of badminton, tennis, and table tennis. The picket racket is a key tool in pickleball; its material, weight, and grip all affect a player's performance. Choosing the right picket racket is crucial for improving shot effectiveness and enjoying the sport.

[0003] Peak rackets currently offer a variety of material options, including lightweight yet strong carbon fiber plates, cost-effective fiberglass, EVA, PE, honeycomb paper, and hybrid materials. These different materials vary in weight, durability, and feel, allowing players to choose according to their needs and preferences. Furthermore, the manufacturing processes for different materials also differ.

[0004] To improve the elasticity of Peak racket faces, an elastic material is filled inside the racket face during the production process. In existing technology, the common elastic material used for filling the racket face is thermoforming foam. This thermoforming foam requires hot pressing using a mold, during which the foam undergoes secondary foaming to achieve a tight filling effect. Therefore, this racket face structure filled with thermoforming foam requires hot pressing using a mold, resulting in high production costs. Furthermore, the hot pressing process requires a long time for secondary foaming, leading to high overall production costs. In addition, while racket faces filled with foam have good elasticity, the lack of lateral tensile strength in the foam results in insufficient overall rigidity of the racket face, making it prone to damage with prolonged use and leading to poor overall durability of Peak rackets. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned deficiencies and provide a cold-pressed reinforced Peak racket. It adds a hollow carbon fiber tube inside the racket face of the honeycomb core material, which can increase the strength of the honeycomb core material and make the ball hit more solidly, thus solving the technical problem of poor overall strength of the honeycomb core material in the prior art.

[0006] The objective of this utility model is achieved through the following means:

[0007] The cold-pressed reinforced Peak racket includes a honeycomb core material, a carbon fiber faceplate, and a carbon fiber base plate. The carbon fiber faceplate and carbon fiber base plate are fixedly attached to the top and bottom surfaces of the honeycomb core material, respectively. The honeycomb core material, carbon fiber faceplate, and carbon fiber base plate all include a racket face and a handle. The handle extends outward from one end of the racket face. The inside of the racket face of the honeycomb core material is provided with a receiving cavity. The receiving cavity extends horizontally from one end of the racket face of the honeycomb core material to the other end, and a hollow carbon fiber tube is tightly filled in the receiving cavity. The hollow carbon fiber tube completely fills the entire receiving cavity.

[0008] Furthermore, the extending direction of the receiving cavity is the same as the extending direction of the handle portion.

[0009] Furthermore, the receiving cavity and hollow carbon fiber tube near the handle of the honeycomb core material both extend into the interior of the handle of the honeycomb core material.

[0010] Furthermore, the extending direction of the receiving cavity is perpendicular to the extending direction of the handle portion.

[0011] Furthermore, the sides of the clapping surface of the honeycomb core material, carbon fiber panel, and carbon fiber base plate are wrapped with edge protectors, which are then glued and fixed in place.

[0012] Furthermore, both the receiving cavity and the hollow carbon fiber tube are provided with an even number of sections.

[0013] Furthermore, both the receiving cavity and the hollow carbon fiber tube are provided with an odd number of tubes.

[0014] Furthermore, the sides of the honeycomb core material, carbon fiber panel and carbon fiber base plate are wrapped with support strips to increase lateral support. The support strips are composed of foam strips and a carbon fiber outer shell wrapped around the surface of the foam strips.

[0015] Furthermore, a first nonwoven fabric layer is bonded to the top surface of the honeycomb core material and the carbon fiber panel with adhesive, and a second nonwoven fabric layer is bonded to the bottom surface of the honeycomb core material and the carbon fiber base plate with adhesive.

[0016] Furthermore, the handle portion of the honeycomb core material, carbon fiber panel, and carbon fiber base plate is provided with a grip clamp and an end cap, and is provided with hand adhesive for wrapping the grip clamp.

[0017] The beneficial effects of this invention are as follows: A receiving cavity is provided inside the racket face of the honeycomb core material, and the receiving cavity is tightly filled with hollow carbon fiber tubes. The hollow carbon fiber tubes possess horizontal tensile force, which not only provides a tight connection and reinforcement, making the overall rigidity of the honeycomb core material better, improving overall quality and durability, but also provides good resilience, allowing the racket face to generate better rebound force during the hitting process. Combined with the carbon fiber faceplate and carbon fiber baseplate, the overall racket face has good elasticity and high rigidity, making the hitting process feel more solid and powerful, and making the strokes and control more comfortable and less strenuous. In addition, the hollow carbon fiber tubes do not require hot pressing production and can be produced using cold pressing technology, resulting in lower production costs. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] In this embodiment, refer to Figures 1-4 The specific implementation of the cold-pressed reinforced Peak racket includes a honeycomb core material 1, a carbon fiber panel 2, and a carbon fiber base plate 3. The carbon fiber panel 2 and the carbon fiber base plate 3 are respectively fixedly attached to the top and bottom surfaces of the honeycomb core material 1. A first non-woven fabric layer 4 is glued between the top surface of the honeycomb core material 1 and the carbon fiber panel 2. A second non-woven fabric layer 5 is glued between the bottom surface of the honeycomb core material 1 and the carbon fiber base plate 3. The first non-woven fabric layer 4 and the second non-woven fabric layer 5 are glued to the honeycomb core material 1 before it is cut into the shape of the racket.

[0030] The honeycomb core material 1, carbon fiber panel 2, and carbon fiber base plate 3 all include a racket face 101 and a handle portion 102. The handle portion 102 extends outward from one end of the racket face 101. The sides of the racket face 101 of the honeycomb core material 1, carbon fiber panel 2, and carbon fiber base plate 3 are wrapped with edge protectors 6, which are fixed by adhesive. The handle portion 102 of the honeycomb core material 1, carbon fiber panel 2, and carbon fiber base plate 3 is provided with a grip clamp 7 and an end cap 8, and is provided with adhesive tape 9 for wrapping the grip clamp 7.

[0031] The honeycomb core material 1 has a receiving cavity 103 inside the patting surface 101. The receiving cavity 103 extends horizontally from one end of the patting surface 101 of the honeycomb core material 1 to the other end, and a hollow carbon fiber tube 104 is tightly filled in the receiving cavity 103. The hollow carbon fiber tube 104 completely fills the entire receiving cavity 103. The outer diameter of the hollow carbon fiber tube 104 matches the inner diameter of the receiving cavity 103 and the length is the same. The hollow carbon fiber tube 104 is installed into the corresponding receiving cavity 103 by interference fit.

[0032] In this embodiment, the extending direction of the receiving cavity 103 is the same as the extending direction of the handle portion 102. Two receiving cavities 103 are provided inside the beater surface 101 of the honeycomb core material 1. The two receiving cavities 103 are symmetrical about the center line of the handle portion 102. Two hollow carbon fiber tubes 104 are respectively inserted into the corresponding receiving cavities 103 by interference fit.

[0033] The cold-pressed reinforced Peak racket of this embodiment is manufactured using a cold-pressing process, eliminating the need for hot-pressing shaping with molds. The specific process includes the following steps: First, prepare a honeycomb core material 1, a carbon fiber faceplate 2, and a carbon fiber base plate 3. These materials are large sheet structures. The shape of the Peak racket is planned according to dimensions on the honeycomb core material 1, carbon fiber faceplate 2, and carbon fiber base plate 3. Alternatively, the cutting path can be preset directly on the computer program of the cutting machine for precise cutting. Then, drill corresponding receiving cavities 103 along the side of the honeycomb core material 1 using a drilling device, and prepare hollow carbon fiber tubes 104 that match the receiving cavities 103. The hollow carbon fiber tubes 104 are then tightly fitted into the corresponding receiving cavities 103. Next, cold pressing is performed. Adhesive is applied to the top and bottom surfaces of the honeycomb core material 1, and the carbon fiber panel 2 and carbon fiber base plate 3 are respectively bonded to the top and bottom surfaces of the honeycomb core material 1. Then, multiple layers are stacked and pressed simultaneously using a pressing device. Since the pressing process does not require heating, the requirements for the pressing equipment are not high, and the cost of cold pressing is lower. Finally, the finished product is assembled. The edge protector 6 is fixed with quick-drying adhesive, and then pressed and fixed. The edge protector 6 extends to the handle portion 102. Finally, the grip clamp 7 and end cap 8 are installed. The grip clamp 7 clamps the handle portion 102 along both sides, and hand grip tape 9 is wrapped around the handle portion 102.

[0034] Example 2

[0035] In this embodiment, refer to Figures 5-6 The difference between the cold-pressed reinforced Peak racket implemented in this embodiment and the first embodiment is that both the receiving cavity 103 and the hollow carbon fiber tube 104 are provided with an even number of lines. Specifically, there are four receiving cavities 103. The shape, size and number of hollow carbon fiber tubes 104 are consistent with those of the receiving cavities 103. The four receiving cavities 103 are symmetrical about the center line of the handle part 102. Two receiving cavities 103 are provided on each side of the center line of the handle part 102. The four hollow carbon fiber tubes 104 are inserted into the corresponding receiving cavities 103 by interference fit.

[0036] Example 3

[0037] In this embodiment, refer to Figures 7-8The difference between the specific implementation of the cold-pressed reinforced Peak racket and the first embodiment is that both the receiving cavity 103 and the hollow carbon fiber tube 104 have an odd number of sections. Specifically, there are three receiving cavities 103. The two receiving cavities 103 on both sides are symmetrically arranged along the receiving cavity 103 in the middle. The shape, size and number of the hollow carbon fiber tubes 104 are consistent with those of the receiving cavities 103. The receiving cavity 103 and the hollow carbon fiber tubes 104 located in the middle and close to the handle portion 102 of the honeycomb core material 1 extend into the handle portion 102 of the honeycomb core material 1. The hollow carbon fiber tubes 104 located in the middle extend into the handle portion 102 of the honeycomb core material 1, which serves to connect and pull the handle portion 102 of the honeycomb core material 1, thereby enhancing the rigidity of the handle portion 102 of the honeycomb core material 1 and providing a tight connection and reinforcement to the handle portion 102. The hollow carbon fiber tube 104 provides good resilience, allowing the racket face 101 to generate better rebound force during the hitting process. Combined with the carbon fiber panel 2 and the carbon fiber base plate 3, the overall racket face 101 has good elasticity and high rigidity, making the hitting process more solid and powerful, and making the stroke and control more comfortable and less strenuous. In addition, the hollow carbon fiber tube 104 does not require hot pressing production and can be produced by cold pressing process, which reduces production costs.

[0038] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
