[0025] The following Figures 1 to 4 and preferred embodiments are used to further illustrate the present utility model.

[0026] As Figure 1 and 2 shown, this embodiment discloses a rough panel 10 with an identification layer 13, including: a carbon cloth layer 11; a rough layer 12 provided on the carbon cloth layer 11; wherein, an identification layer 13 is provided between the carbon cloth layer 11 and the rough layer 12, and the rough panel 10 is made by compression molding, and the identification layer 13 is embedded in the carbon cloth layer 11 and / or the rough layer 12.

[0027] By disposing the identification layer 13 between the carbon cloth layer 11 and the rough layer 12, the wear of the identification layer 13 can be effectively avoided, enabling the identification layer 13 to be better displayed. Moreover, the identification layer 13 can be embedded into the carbon cloth layer 11 and / or the rough layer 12 through molding, so that no protrusion is formed at the position of the rough layer 12 corresponding to the identification layer 13. The rough panel 10 can be used to make a beach ball or a paddle 20 of a Pickleball, ensuring the integrity of the cover plate 23 and the rough cover plate 10 while having better strength. At the same time, when the rough panel 10 is manufactured into a paddle 20, the rough layer 12 can effectively increase the rotation speed of the cut ball, achieving a better cut ball effect.

[0028] Among them, the identification layer 13 uses single-color or multi-color labels, and the labels are set in the shape of trademark words or patterns. Generally, the identification layer 13 uses labels of a color different from that of the carbon cloth, making the labels set as trademark words or patterns more prominent. When manufactured into a paddle 20, it can better display the trademark and will not be worn due to hitting the ball.

[0029] Among them, the labels are made of carbon fiber and / or glass fiber. The labels made of carbon fiber and / or glass fiber are better than paper materials in terms of strength, impact resistance, and fracture safety, and can be better fixed between the carbon cloth layer 11 and the rough layer 12 through the molding process. Optionally, the label is pasted on the sweet spot, enabling different hitting effects in terms of structural characteristics such as the strength, elasticity, hardness, friction, or sound of the hitting surface of the paddle 20 in the sweet spot, such as the difference in hitting feel or hitting sound achieved by the paddle 20.

[0030] Among them, the labels are made of poly-p-phenylene terephthalamide material, and the poly-p-phenylene terephthalamide material corresponds to the foreign trade name Kevlar and the domestic trade name Typron.

[0031] Among them, the carbon cloth layer 11 is made by impregnating carbon cloth with epoxy resin and molding it through pressing, which can effectively improve the strength and ductility of the rough panel 10, be more impact-resistant, and will not completely separate after fracture, improving the safety factor.

[0032] Among them, the rough layer 12 is made by impregnating a release cloth with epoxy resin, molding it, and then peeling off the release cloth. After the release cloth impregnated with epoxy resin is cured and formed, it can be easily torn off and a rough woven texture is formed on the surface of the rough panel 10. When the rough panel 10 is manufactured into a paddle 20, the rough layer 12 can effectively increase the rotation speed of the cut ball, achieving a better cut ball effect.

[0033] Such as Figure 3As shown in the figure, another embodiment of the present utility model lies in a racket 20, which includes a cover plate 23 made of the above-mentioned rough panel 10, a handle part 30 and a racket part. The racket part is fixedly connected to the handle part 30. The handle part 30 includes a handle 31, and the racket part includes a frame 21 and a core board 22. The handle 31 and the frame 21 are integrally formed into a main frame 25. An installation position 24 is provided on the main frame 25, and the core board 22 can be detachably arranged in the installation position 24, and the cover plate 23 can be detachably arranged on the main frame 25.

[0034] By detachably installing the core board 22 and the cover plate 23 on the main frame 25, both the core board 22 and the cover plate 23 can be replaced according to the needs of users. Different combinations of the core board 22 and the cover plate 23 enable structural characteristics such as the strength, elasticity, hardness, friction or sound of the hitting surface of the racket 20 to achieve different hitting effects, such as differences in the hitting feel or hitting sound achieved by the racket 20; moreover, the main frame 25 is integrally formed by the handle 31 and the frame 21, which can further reduce the components that need to be assembled in the racket 20, making the assembly of the racket 20 and the replacement operation of the core board 22 and the cover plate 23 simpler; of course, the main frame 25 can also be replaced according to the needs of users, and this racket 20 can be applied to Pickleball rackets, beach tennis rackets, etc.

[0035] Among them, two cover plates 23 are provided. The cover plate 23 includes a flat plate 231 and a side wrap 232. The side wrap 232 is integrally formed along the edge of the flat plate 231. A chamfer is provided between the flat plate 231 and the side wrap 232 to better fit the main frame 25 while ensuring better usage requirements; the two cover plates 23 are installed on the main frame 25 from both sides of the racket part, and the side wraps 232 of the two cover plates 23 cooperate to cover the outer side surface of the frame 21. By fitting and installing the two cover plates 23 on the main frame 25 from both sides of the racket part respectively, the whole of the main frame 25 and the core board 22 can be effectively sealed and shielded, further ensuring the installation stability of the core board 22.

[0036] Among them, a removable adhesive layer 233 is provided on the inner side of the cover plate 23. The thickness range of the adhesive layer 233 is that the thickness of the adhesive layer 233 is 20 - 150 microns, and generally a thickness of 50 microns is set, which can ensure a better pasting effect while effectively reducing the overall thickness of the racket 20; the thickness of the adhesive layer 233 can be selected according to the thickness of the relevant core board 22. By setting a removable adhesive layer 233 on the inner surface of the cover plate 23, the adhesive layer 233 can optionally be a removable double-sided tape, which is convenient for users to replace a suitable cover plate 23 according to their own needs and better meet the usage requirements.

[0037] Among them, the core board 22 includes a composite board made of any one or more of a PP board, a cork board, and an EVA board stacked. The EVA board has better elasticity and can effectively reduce noise. The PP board has better strength and stronger hitting ability, and users can choose according to their needs. It is also possible to select and form a composite board by combining the characteristics of the EVA board, the PP board, the cork board, or the balsa wood board to better meet the usage requirements. The PP board can optionally be a PP honeycomb board. Moreover, different material combinations are used for the core board 22 and the cover board 23, so that the structural characteristics such as the strength, elasticity, hardness, friction, or sound of the hitting surface of the racket 20 can achieve different hitting effects, such as the difference in the hitting feel or hitting sound achieved by the racket 20.

[0038] As Figure 4 shown, the core board adopts a three-layer composite structure. By arranging the cork board between the PP honeycomb boards 221 to form a composite board, it can ensure better hitting effects while making the overall racket 20 lightweight. Through the setting of the cork board 222, the weight of the racket 20 can be effectively reduced, making the use of the racket 20 more comfortable, and having better elasticity and compressibility, which can be quickly compressed and rebounded when hitting the ball to ensure a better hitting feel. Moreover, it can ensure good support performance of the core board 22 while achieving good sound insulation performance and effectively reducing impact noise. And the cork board 222 made of cork is relatively environmentally friendly and also has good wear resistance. Even when compressed, it can still maintain a high recovery property. Of course, the cork board 222 can optionally be replaced with an EVA board. At the same time, the flat plate 231 can not only effectively protect the core board 22, but also increase the friction between the hitting surface of the racket 20 and the Pickleball when hitting the ball, improve the rotation speed of the Pickleball, and further optimize the feel when swinging the racket 20.
