DETAILED DESCRIPTION OF THE INVENTION

[0023] The following describes the specific embodiments of the present invention with reference to the accompanying drawings. To fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0024] Embodiment 1 Refer to Figure 2 and Figure 3 , the anti-bending moment Pickleball racket includes a racket body unit 1, a reinforcement 2, and a panel unit 3.

[0025] The racket body unit 1 is composed of a first intermediate layer 11, a second intermediate layer 12, and a racket body 13 connected between the first intermediate layer 11 and the second intermediate layer 12. The racket body unit 1 includes a racket face portion 14 and a handle portion 15 connected to the racket face portion 14 and extending along an axis L. A filling space 16 is formed on the racket body unit 1 at the connection between the racket face portion 14 and the handle portion 15. The filling space 16 has a first opening 161 formed in the first intermediate layer 11 and a second opening 162 formed in the second intermediate layer 12. Therefore, the first opening 161 and the second opening 162 are located on two opposite sides of the racket body unit 1. In this embodiment, the first intermediate layer 11 and the second intermediate layer 12 are made of polyester. The racket body 13 is a honeycomb board and is made of polypropylene (PP).

[0026] Referring to Figures 2 to 4 , the reinforcing member 2 is disposed in the filling space 16. The reinforcing member 2 includes a first plate 21 and a second plate 22. Specifically, the first plate 21 and the second plate 22 are made of carbon fiber. The first plate 21 has a node portion 211, a handle branch portion 212 extending from the node portion 211 toward the handle portion 15, and an intermediate branch portion 213 extending from the node portion 211 toward the racket face portion 14. A first card slot 214 is formed on the node portion 211. The second plate 22 is bent into a V shape to form two racket face branch portions 221, and a second card slot 222 for engaging with the first card slot 214 is formed between the two racket face branch portions 221. After the first plate 21 and the second plate 22 are assembled in the filling space 16, the first card slot 214 and the second card slot 222 are engaged; the first plate 21 is located on the axis L and extends along the axis L; the two racket face branch portions 221 extend from the node portion 211 toward the racket face portion 14, and the two racket face branch portions 221 are located on two opposite sides of the axis L and also on two opposite sides of the intermediate branch portion 213. The handle branch portion 212, the intermediate branch portion 213, and the racket face branch portion 221 are plate-shaped, but are not limited thereto. In other embodiments, the handle branch portion 212, the intermediate branch portion 213, and the racket face branch portion 221 may also be tubular, polygonal columnar, or other elongated shapes.

[0027] The panel unit 3 includes a first panel 31 and a second panel 32. Among them, the first panel 31 is connected to one side of the racket body unit 1 where a first opening 161 is provided, and the second panel 32 is connected to the other side of the racket body unit 1 where a second opening 162 is provided. Specifically, the first panel 31 and the second panel 32 are carbon fiber plates. The first panel 31 is connected to the first intermediate layer 11 and is connected to one side of the handle branch 212, the middle branch 213, and the racket face branch 221 through the first opening 161. The second panel 32 is connected to the second intermediate layer 12 and is connected to the other side of the handle branch 212, the middle branch 213, and the racket face branch 221 through the second opening 162.

[0028] Since the two racket face branches 221 are arranged in the racket body unit 1 and on two opposite sides of the axis L, the two racket face branches 221 can resist the rotation of the panel unit 3 around the axis L, improve the bending moment resistance of the panel unit 3 around the axis L, and improve the strength and anti-bending ability of the connection between the racket face part 14 and the handle part 15.

[0029] Refer to Figure 5 , the manufacturing method of the anti-bending moment Pickleball racket of the present invention includes a racket body manufacturing step S1, a hole opening step S2, a reinforcement member manufacturing step S3, a filling step S4, and a bonding step S5.

[0030] Refer to Figure 6 , in the racket body manufacturing step S1, the first intermediate layer 11 and the second intermediate layer 12 are respectively bonded to two opposite sides of a racket body 13 to form a first semi-finished product 4.

[0031] Refer to Figure 2 and Figure 7 , in the hole opening step S2, a filling space 16 is opened in the first semi-finished product 4 to form a racket body unit 1. The racket body unit 1 has a racket face part 14 and a handle part 15. The handle part 15 is connected to the racket face part 14 and extends along an axis L. The filling space 16 is located at the connection between the racket face part 14 and the handle part 15. The filling space 16 has a first opening 161 formed in the first intermediate layer 11 and a second opening 162 formed in the second intermediate layer 12.

[0032] Refer to Figure 4, in the manufacturing step S3 of the reinforcement member, a first card slot 214 is cut out on the first plate 21. After the second plate 22 is bent into a V shape, a second card slot 222 is cut out at the bent portion. The second card slot 222 is engaged with the first card slot 214 to assemble the first plate 21 and the second plate 22 into the reinforcement member 2. Among them, the first plate 21 includes a node portion 211 provided with the first card slot 214, a handle branch portion 212 connected to the node portion 211, and an intermediate branch portion 213 connected to the node portion 211. The second plate 22 includes two racket face branch portions 221, and the two racket face branch portions 221 are located on two opposite sides of the intermediate branch portion 213. The thickness of the reinforcement member 2 is slightly smaller than the thickness of the racket body unit 1.

[0033] Refer to Figure 2 and Figure 8 , in the filling step S4, the reinforcement member 2 is filled into the filling space 16 to form a second semi-finished product 5, so that the handle branch portion 212 extends toward the handle portion 15, the intermediate branch portion 213 extends toward the racket face portion 14, and the two racket face branch portions 221 extend toward the racket face portion 14 and are located on two opposite sides of the intermediate branch portion 213.

[0034] Refer to Figure 8 and Figure 9 , in the bonding step S5, the first panel 31 is disposed on one side of the second semi-finished product 5 where the first opening 161 is provided, and the second panel 32 is disposed on the other side of the second semi-finished product 5 where the second opening 162 is provided. Then, through hot pressing and bonding, the first panel 31 is connected to one side of the racket body unit 1 and is connected to the handle branch portion 212 and the two racket face branch portions 221 through the first opening 161; through hot pressing and bonding, the second panel 32 is connected to the other side of the racket body unit 1 and is connected to the handle branch portion 212 and the two racket face branch portions 221 through the second opening 162. Thus, the finished product (i.e., the anti-bending moment pick racket) is formed. Since the thickness of the reinforcement member 2 is slightly smaller than the thickness of the racket body unit 1, it can avoid excessive extrusion of the first panel 31 and the second panel 32 when the reinforcement member 2 expands due to heat, and keep the first panel 31 and the second panel 32 flat. Moreover, the reinforcement member 2, the first panel 31, and the second panel 32 are all made of carbon fiber material, and the connection strength of hot pressing and bonding is high, which can further improve the anti-bending moment ability of the panel unit 3 around the axis L.

[0035] Embodiment 2 Refer to Figure 4 and Figure 10 , the difference between Embodiment 2 and Embodiment 1 is that: the reinforcement member 2' does not have the intermediate branch portion 213, and the first plate 21 is connected to the second plate 22, and the whole is in a Y shape. Therefore, the two racket face branch portions 221 of the reinforcement member 2' can also resist the rotation of the panel unit 3 around the axis L. Therefore, Embodiment 2 can also improve the anti-bending moment ability of the panel unit 3 around the axis L.

[0036] Embodiment III Refer to Figure 4 and Figure 11 In Embodiment III, the difference from Embodiment I is that the reinforcing member 2" is tubular. Specifically, the handle branch portion 212, the middle branch portion 213, and the two racket face branch portions 221 are all tubular. Therefore, the two racket face branch portions 221 of the reinforcing member 2" can also resist the rotation of the panel unit 3 around the axis L. Thus, Embodiment III can also improve the bending moment resistance of the panel unit 3 around the axis L.

[0037] In summary, for the bending moment resistant badminton racket of the present invention, by means of the racket face branch portions 221 of the reinforcing member 2 located on the two opposite sides of the axis L, it can resist the bending of the panel unit 3 around the axis L, so as to improve the bending moment resistance of the panel unit 3 around the axis L, as well as the strength and anti-bending ability of the connection between the racket face portion 14 and the handle portion 15. When hitting the ball, it can prevent the racket face portion 14 from bending relative to the handle portion 15. When hitting the ball at a position far from the axis L on the panel unit 3, it can also prevent the panel unit 3 from rotating and deforming around the axis L, so that the swinging force can be completely transmitted to the ball, improving the ball rebound ability and hitting stability, enabling the user to easily control the path of the returned ball. And because the reinforcing member 2 is arranged in the racket body unit 1 and is tightly combined with the panel unit 3, the surfaces of the first panel 31 and the second panel 32 are kept flat as a whole, having a uniform hitting rebound effect.

[0038] Moreover, by means of the middle branch portion 213 extending between the two racket face branch portions 221, the contact area between the reinforcing member 2 and the racket body unit 1 and the panel unit 3 is increased, which can further improve the bending moment resistance of the panel unit 3 around the axis L and further improve the strength and anti-bending ability of the connection between the racket face portion 14 and the handle portion 15.

[0039] The above is only the specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modification made to the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
