Description

Technical Field

[0001] The utility model relates to the technical field of ball sports equipment, especially to the technical field of rough board composite fabrics in beach rackets and Pickleball rackets. Background Art

[0002] With the rise of Pickleball sports, more and more people and sports enthusiasts are involved in Pickleball sports. The manufacturing process of Pickleball rackets has also been continuously upgraded and improved according to the usage needs of consumers to meet better usage requirements and provide a better usage experience.

[0003] Whether it is a Pickleball racket or a beach racket, it needs to meet certain requirements for hitting elasticity and impact resistance, and under the requirements of the wear-resistant and impact-resistant performance of the racket, it also needs to take into account the requirement of light weight. This poses relatively high requirements for the manufacturing process and materials of the racket. For example, the disclosed patent CN202322998140.X, an impact-absorbing and wear-resistant Pickleball racket, discloses that buffer surfaces are installed on the opposite surfaces at the front and rear ends of the racket board surface, which can offset part of the impact force after the ball collides with the buffer surface, reducing the impact force received by the board surface and achieving the shock-absorbing effect.

[0004] However, according to the content recorded in the disclosed literature, a buffer spring is provided in the buffer surface of the Pickleball racket. This structure is not only complex but also will significantly increase the weight of the racket, which is not conducive to reducing the overall weight of the racket. Moreover, if only considering the good buffer effect and ignoring the importance of the strength of the racket core material, it will also lead to the racket being not durable, being easily broken after being used for a period of time, resulting in a short service life and large losses of the racket. Summary of the Invention

[0005] The utility model proposes a racket core material made of buffer materials for the above problems, and makes the racket core material into a racket with light weight, good buffer effect, good hitting rebound elasticity, good durability of the core material, and long service life.

[0006] The racket core material structure of the buffer material includes a panel layer and a structure layer. The panel layer includes a first panel layer and a second panel layer, and the structure layer is sandwiched between the first panel layer and the second panel layer, and is hot-pressed into one body through a coated resin adhesive layer. The structure layer includes male and female buffer layers that are mutually embedded, and the opposite sides of the male and female buffers have an uneven structure that is mutually nested, and form the structure layer after being nested in place.

[0007] The structure layer includes a layer of male buffer layer, a layer of female buffer layer, and a middle core layer sandwiched between the male buffer layer and the female buffer layer; the male buffer layer refers to a buffer layer facing the hitting surface, and the female buffer layer is a buffer layer that supports the male buffer layer.

[0008] The middle core layer is made of carbon fiber or glass fiber material, and its shape is in a continuous concave-convex shape, matching the concave-convex position structure of the male and female buffer layers that are nested with each other.

[0009] The male buffer layer and the female buffer layer of the structure layer are nested and combined with each other through the concave-convex position structure, where the concave-convex position structure is a triangular concave-convex groove structure, a rectangular concave-convex groove structure or a trapezoidal concave-convex groove structure.

[0010] Both the male buffer layer and the female buffer layer are made of foaming material or EVA material.

[0011] The racket core material made of the buffer material of the present utility model can meet the requirements of light weight. By combining the characteristics of various materials, the effects of reducing noise during hitting, good resilience, good durability of the core material and long racket life are obtained. At the same time, due to the male and female buffer layers composed of different hardness combinations, the effect of different soft and hard degrees on both sides of the racket is achieved, bringing the advantage of different hitting characteristics on both sides.

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0018] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0019] Please refer to the attached Figure 1 , which shows that the racket core structure of the cushioning material includes a panel layer 10 and a structure layer 20. The panel layer 10 includes a first panel layer 11 and a second panel layer 12, and the structure layer 20 is sandwiched between the first panel layer 11 and the second panel layer 12 and is integrally formed by hot pressing through a coated resin adhesive layer. The structure layer 20 includes male and female cushioning layers that are mutually interlocked, and the opposite sides of the male and female cushioning layers have an uneven structure 30 with mutual nesting. After the alignment and nesting, the structure layer 20 is formed.

[0020] The structure layer 20 includes a layer of male cushioning layer 21, a layer of female cushioning layer 22, and a core layer 23 sandwiched between the male cushioning layer 21 and the female cushioning layer 22. The male cushioning layer 21 refers to a cushioning layer facing the hitting surface, and the female cushioning layer 22 is a cushioning layer that supports the male cushioning layer.

[0021] The core layer is made of carbon fiber or glass fiber material, and its shape is in a continuous uneven shape, matching the uneven structure of the mutual nesting of the male and female cushioning layers. Using carbon fiber or glass fiber to support the structure of the male and female cushioning material layers highlights the high strength characteristics of carbon fiber and glass fiber. At the same time, it is an excellent memory material with good anti-pressure deformation ability and can maintain the shaping of the uneven structure of the male and female cushioning material layers.

[0022] The male cushioning layer 21 and the female cushioning layer 22 of the structure layer 20 are mutually nested and combined through the uneven structure 30. The uneven structure 30 is a triangular uneven groove structure, a rectangular uneven groove structure, or a trapezoidal uneven groove structure. By using the uneven structure, the male and female cushioning layers can be restrictively positioned by nesting one concave and one convex, avoiding large deformation and displacement during the thermoplastic and hot pressing processes.

[0023] Both the male buffer layer 21 and the female buffer layer 22 are made of foaming materials or EVA materials. The male buffer layer 21 and the female buffer layer 22 can be made of foaming materials with different degrees of foaming. The main parameter is reflected in the different material densities brought by different degrees of foaming. If the density is high and the texture is firm, it will be harder, with strong hitting power and moderate resilience; while if the density is low, the texture will be softer, the racket will be softer and the resilience will be strong. Therefore, by using different male and female buffer layers to make the racket core material, it is possible to achieve a combination of different hardness racket faces on the two sides of a racket, so that the two sides of the racket have different hitting characteristics, one side is soft and comfortable, and the other side is hard and solid.

[0024] After hot-pressing the materials into one body, then die-cut the product shape according to the shape of the racket, or the core material can also be formed into the shape of the racket face in a mold. Finally, make the racket covering material. The racket core material structure can be covered on the racket plate in a longitudinal manner, as shown in the appendix Figure 2 . It can also be covered on the racket plate in a transverse manner, as shown in the appendix Figure 3 .

[0025] The racket core material made of the buffer material described in the present invention can meet the requirements of lightweight. By combining the characteristics of each material, the effects of reducing hitting noise, good resilience, good durability of the core material, and long racket life are obtained. At the same time, due to the use of male and female buffer layers combined with different hardnesses, the effects of different softness and hardness on the two sides of the racket are achieved, bringing the advantages of different hitting characteristics on the two sides.

[0026] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Although the present invention is disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications using the above-disclosed technical content as equivalent change equivalent embodiments, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical meaning of the present invention shall fall within the scope of the technical solution of the present invention.
