[0032] Embodiment 1.

[0033] Refer to Figures 1-3As shown in the figure, as an embodiment of the present invention, a lightweight and highly elastic Pickleball racket is provided, which includes a connected racket board 1 and a racket handle 2. The racket board 1 is a pear-shaped board or an oval board with a certain thickness. The racket board 1 includes an inner core and hitting surfaces 3 connected to opposite sides of the inner core. The two sides corresponding to the two hitting surfaces 3 are defined as the upper side and the lower side respectively. The inner core includes at least one elastic layer 4 arranged parallel to the hitting surface 3, and the elastic layer 4 is formed with a plurality of high surfaces 41, supporting vertical surfaces 42 and low surfaces 41. The high surfaces 41 and the low surfaces 41 are arranged alternately, and the supporting vertical surfaces 42 are located between adjacent high surfaces 41 and low surfaces 41. A hollow cavity 5 is formed by enclosing between a high surface 41 and its two adjacent supporting vertical surfaces 42, and between a low surface 43 and its two adjacent supporting vertical surfaces 42. Among them, the longitudinal section of the elastic layer 4 is in a square wave structure. The high surfaces 41 and the low surfaces 41 are respectively parallel to the hitting surface 3, and the widths of the high surfaces 41 and the low surfaces 41 are the same. The supporting vertical surfaces 42 are perpendicular to the hitting surface 3. There are two elastic layers 4 arranged up and down, and the low surface 41 of the upper elastic layer 4 is relatively and fittingly connected to the high surface 41 of the lower elastic layer 4. The high surface 41 of the upper elastic layer 4 is fittingly connected to the upper hitting surface 3, and the low surface 43 of the lower elastic layer 4 is fittingly connected to the lower hitting surface 3. This enables the inner core to use less material overall while ensuring a conventional thickness, making it more lightweight, having a larger internal hollow space, and higher elastic performance. Moreover, the high surfaces 41, the supporting vertical surfaces 42 and the low surfaces 41 are flat strips, and all the high surfaces 41 on each elastic layer 4 are on the same plane, and all the low surfaces 41 on each elastic layer 4 are on the same plane. Thus, it is convenient to fixedly connect the high surface 41 of the upper elastic layer 4 to the upper hitting surface 3 and fixedly connect the low surface 41 of the lower elastic layer 4 to the lower hitting surface 3, and the connection effect is more stable and reliable. Additionally, the included angle between the length direction of the high surface 41, or the supporting vertical surface 42, or the low surface 41 and the length direction of the racket handle 2 is 45°, that is, the included angle between the hollow cavity 5 and the length direction of the racket handle 2 is 45°. This makes the present invention not easily undergo torsional deformation and be damaged during the hitting process, having a longer service life, and thus ensuring the user experience of players.

[0034] The technical solution formed by combining the above structural features makes the overall strength of the Pickleball racket of the present invention higher, uses less material, has the performance advantages of being lightweight and highly elastic, and is not easily affected by the force of the ball during the hitting process and undergo torsional deformation, being more durable and having an extended service life, thereby ensuring the user experience of players.

[0035] Of course, in other embodiments, the included angle between the hollow cavity 5 and the length direction of the racket handle 2 can be other angles between 0° and 90°. It's just that the Pickleball racket is easily affected by the force of the ball during the hitting process and undergo torsional deformation, affecting the service life and the user experience.

[0036] In this embodiment, there are two elastic layers 4 arranged up and down. By connecting the two elastic layers 4 up and down, an integral elastic member is formed. Of course, in other cases, it is also possible to integrally form the above two upper and lower elastic layers 4 into an integral elastic member. Similarly, it is also possible to have only one elastic layer. The elastic layer includes an upper elastic layer and a lower elastic layer integrally formed up and down. The upper elastic layer and the lower elastic layer have the same structure, and the hollow cavity is formed inside the upper elastic layer and the lower elastic layer.

[0037] In this embodiment, the elastic layer 4 includes an upper unidirectional cloth surface and a lower unidirectional cloth surface connected up and down. The upper unidirectional cloth surface includes a plurality of upper unidirectional cloth strips 6 arranged parallel and continuously to each other. The lower unidirectional cloth surface includes a plurality of lower unidirectional cloth strips 7 arranged parallel and continuously to each other. Among them, the upper unidirectional cloth strips 6 and the lower unidirectional cloth strips 7 are perpendicular to each other, and the included angle between the length direction of the upper unidirectional cloth strip 6 and the length direction of the racket handle 2 (such as Figure 3 the direction of the X1 arrow in the figure) is 45°. According to the analysis of the hitting force, this setting makes the connection between the upper unidirectional cloth surface and the lower unidirectional cloth surface more stable, not easily dispersed and separated by the impact of the ball, more firm and reliable, and further extends the service life. Of course, in other embodiments, the included angle between the length direction of the upper unidirectional cloth strip 6 and the length direction of the racket handle 2 can be other angles between 0° and 90°.

[0038] Among them, the inner core is an inner core made of high-performance composite materials. High-performance composite materials are new materials formed by people using advanced material preparation technologies to optimize and combine different properties of material components, including but not limited to materials such as glass fiber, carbon fiber, aramid fiber, ultra-high molecular weight polyethylene fiber, and PET. Combining various high-performance new materials with traditional composite materials makes the racket have better performance. That is, the upper unidirectional cloth strips 6 and the lower unidirectional cloth strips 7 can both be carbon fiber unidirectional cloth strips made of carbon fiber. In addition, the internal material of the racket handle is a PP honeycomb core, and the material of the hitting board surface 3 is glass fiber or carbon fiber material.

[0039] Embodiment 2. For the sake of brief description, this embodiment mainly describes the differences from Embodiment 1.

[0040] Referring to Figures 4-7 As shown, the present invention also provides a lightweight and highly elastic Peak racket. The difference from Embodiment 1 is that the included angle between the hollow cavity 5 and the length direction of the racket handle 2 is 90°. The elastic layer 4 includes at least one woven cloth surface. The woven cloth surface is a woven cloth surface made of composite materials. The woven cloth surface includes a plurality of first woven cloth strips 8 and second woven cloth strips 9 made of carbon fiber material. The first woven cloth strips 8 and the second woven cloth strips 9 are perpendicular to each other and are interwoven into a carbon fiber woven cloth surface. The length direction of the first woven cloth strip 8 and the length direction of the racket handle 2 (such as Figure 7The included angle between the direction of the X2 arrow in the figure and the like is 45°. This setting makes the overall structure of the elastic layer 4 more firm and reliable, not easily prone to the problem of continuous separation and shedding of the woven cloth strips due to the impact of the sphere or external force, and the connection stability is higher.

[0041] Of course, in other embodiments, the included angle between the length direction of the first woven cloth strip 8 and the length direction of the racket handle 2 can be other angles between 0° and 90°.
