Description

Technical Field

[0001] This invention belongs to the field of racket technology, and particularly relates to a Peak racket structure. 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] For example, utility model patent CN223831731U discloses a Peak racket, including a honeycomb core material, a carbon fiber faceplate, and a carbon fiber backplate. The honeycomb core material has an internal cavity extending horizontally from one end to the other. The cavity is tightly filled with hollow carbon fiber tubes. These tubes not only provide a tight connection and reinforcement, improving the overall rigidity and quality of the honeycomb core material and extending its service life, but also impart good resilience, giving the racket face better rebound force during ball hitting. Furthermore, the hollow carbon fiber tubes can be produced using cold pressing instead of hot pressing, resulting in lower production costs.

[0004] The existing Peak rackets have a honeycomb core structure, which is uniform and consistent. While the honeycomb structure ensures the uniformity of the overall strength of the Peak rackets, it also causes the energy of the shot to disperse outwards along the uniform grid of the core during actual hitting, making it difficult to effectively concentrate in the central area. When the core is compressed, it cannot produce significant local elastic deformation and energy storage effect, resulting in poor overall rebound performance. Summary of the Invention

[0005] The purpose of this invention is to provide a Peak racket structure that solves the technical problem that in the existing Peak racket's honeycomb structure core, during actual hitting, the hitting energy is dispersed along the uniform grid to the surrounding areas, making it difficult to effectively concentrate in the central area. When the core center is compressed, it cannot produce significant local elastic deformation and energy storage effect, resulting in poor overall rebound effect of the core.

[0006] To achieve the above objectives, an embodiment of the present invention provides a Peak racket structure, including a core, and a first panel and a second panel located on opposite sides of the core. The core includes a surface core material and a handle core material; the surface core material includes multiple support plates; the multiple support plates are arranged concentrically nested, and are nested layer by layer from the inside to the outside along the radial direction of the core. The support plates in each layer are fixedly connected by several connecting ribs, so that the core material of the entire plate surface forms a mesh structure, and the mesh density of the mesh structure gradually decreases from the inside to the outside.

[0007] Optionally, a connecting gap is provided between two adjacent support plates, and each connecting rib extends outward from the innermost support plate along the width direction of the connecting gap, bridging and penetrating multiple support plates.

[0008] Optionally, one end of each of the connecting ribs is connected to the outer wall of the innermost support plate, and the other end bridging through multiple support plates and connecting to the inner wall of the outermost support plate.

[0009] Optionally, a connecting gap is provided between two adjacent support plates, and multiple connecting ribs are provided in each connecting gap. Each connecting rib extends in a straight line along the width direction of the connecting gap. One end of each connecting rib is fixedly connected to the outer wall of the inner support plate, and the other end is fixedly connected to the inner wall of the adjacent outer support plate.

[0010] Optionally, in the outer region of the core material of the board, the connecting ribs arranged in adjacent connecting gaps are staggered with each other in the circumferential direction of the board surface.

[0011] Optionally, in the central region of the core material of the board, the connecting ribs in two adjacent connecting gaps are arranged both in a staggered manner in the circumferential direction and in a collinear manner in the circumferential direction.

[0012] Optionally, the handle core material includes a handle frame and multiple dividing ribs disposed within the handle frame; the multiple dividing ribs divide the internal space of the handle frame into a grid-like structure.

[0013] Optionally, a buffer gap is provided between the core material of the board surface and the core material of the handle, and the buffer gap is filled with foam material. The foam material is used to block the transmission of vibration from the core material of the board surface to the core material of the handle and to increase the elasticity of the swing.

[0014] Optionally, the core panel further includes an outer frame; the core panel material and the core handle material are both disposed within the outer frame and respectively adhere to the inner wall of the outer frame.

[0015] Optionally, the outer frame has a edging on its side, the edging extending along the side of the outer frame, the edging including an outer skin and a filler; the outer skin encloses to form a cavity, and the filler is housed in the cavity.

[0016] Compared with the prior art, the above-mentioned technical solutions in the Peak racket structure provided by the embodiments of the present invention have at least one of the following technical effects: The various support plates are fixedly connected by several connecting ribs, forming a grid-like structure in the core material of the entire blade with a gradually decreasing mesh density from the inside out. This variable-density grid structure, similar to a spider web, effectively concentrates the energy of the shot in the core hitting area at the center of the racket. When impacted, the core of the blade undergoes localized elastic deformation to store energy, thereby increasing the rebound force after the shot. At the same time, the relatively low-density outer areas have lower rigidity, allowing for greater deformation upon contact with the ball, achieving a combined effect of cushioning, shock absorption, and ball propulsion. Thus, even if the point of impact deviates from the core hitting area, the outer areas can compensate for some of the kinetic energy loss through their own elastic deformation, preventing a sharp decline in elasticity at the edges, improving the return performance, and expanding the effective sweet spot in the player's actual shot perception.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0031] like Figures 1-8As shown, this embodiment discloses a Peak racket structure, including a blade core 100. A first blade surface 200 and a second blade surface 300 are respectively provided on opposite sides of the blade core 100, both made of carbon fiber. The blade core 100 mainly consists of two parts: a blade surface core material 110 and a handle core material 120, which are integrally injection molded.

[0032] The core material 110 of the racket adopts a multi-layer ring support structure design, specifically comprising multiple rounded rectangular support plates 111 with a certain height. These support plates 111 are arranged concentrically, nested layer by layer from the inside out along the radial direction of the racket surface, ensuring uniform and symmetrical stress distribution on the racket surface. The layers of support plates 111 are fixedly connected by several connecting ribs 113, forming a grid-like structure for the entire core material 110. The grid density of this structure gradually decreases from the inside out, meaning the grid is denser in the central area and relatively sparser at the edges.

[0033] The aforementioned mesh structure, similar to a variable-density spider web, makes the mesh arrangement in the central area of ​​the core 100 more dense. This dense mesh gives the central area higher strength and rigidity. When the energy of a shot hits the central area, it doesn't easily diffuse outwards like in a traditional evenly distributed honeycomb structure, effectively concentrating the energy in the core hitting area of ​​the racket. Upon impact, the center of the core 100 undergoes localized elastic deformation to store energy, increasing the racket's rebound force and thus improving the racket's contact depth and ball control time. Simultaneously, the relatively low-density outer areas have lower rigidity, allowing for greater deformation upon contact, creating a combined effect of cushioning, shock absorption, and ball propulsion. Therefore, even if the hitting point deviates from the core hitting area, the outer areas can compensate for some kinetic energy loss through their elastic deformation, preventing a sharp decline in elasticity at the edges, optimizing the return performance, and expanding the effective sweet spot in the player's actual perception. The sweet spot can be understood as the effective hitting area on the racket where the feel is best, power loss is minimal, and vibration is weak.

[0034] In one embodiment, such as Figure 5 As shown, a connecting gap 112 is provided between each pair of adjacent support plates 111. The width of the connecting gap 112 is not uniform and varies. Some connecting ribs 113 extend outward from the innermost support plate 111, spanning and penetrating multiple support plates 111, and are finally fixedly connected to the outermost support plate 111. Other connecting ribs 113 extend outward from the support plate 111 in the middle position and are fixedly connected to the inner wall of the adjacent support plate 111. Multiple connecting ribs 113 connect multiple layers of independent support plates 111 into a whole, effectively improving the overall structural strength of the core material 110.

[0035] In another embodiment, such as Figure 6 As shown, a uniformly wide connecting gap 112 is provided between each pair of adjacent support plates 111. A connecting rib 113 extends outward from the innermost support plate 111, bridging and passing through multiple support plates 111, and finally connecting to the outermost support plate 111. The connecting rib 113 connects multiple independent support plates 111 into a single unit, improving the overall structural strength of the core material 110 and creating a continuous force transmission path along the width direction of the connecting gap 112, i.e., the radial direction. When the hitting force acts on the racket face, the force can be quickly transmitted from the hitting point along the radial connecting rib 113 to each support plate 111, and then dispersed along the circumferential direction by the support plates 111, effectively preventing localized stress concentration.

[0036] Furthermore, the specific arrangement of the connecting ribs 113 is such that one end of each connecting rib 113 is connected to the outer wall of the innermost support plate 111, and the other end extends outward in sequence, bridging and penetrating multiple support plates 111 and connecting to the inner wall of the outermost support plate 111.

[0037] It is understandable that multiple support plates 111 and multiple connecting ribs 113 make the core material 110 of the plate form a mesh structure. The size of the support plate 111 gradually increases from the center to the outside, and the corresponding connecting gap 112 also increases accordingly. However, the number of connecting ribs 113 arranged inside each connecting gap 112 remains constant and is evenly distributed. Therefore, the mesh density in the outer area is less than that in the central area, forming a structure in which the mesh density gradually decreases from the center to the outside.

[0038] In another embodiment, such as Figure 7 As shown, the connecting gap 112 formed by adjacent support plates 111 is provided with multiple connecting ribs 113. Each connecting rib 113 extends linearly along the width direction of the connecting gap 112. One end of each connecting rib 113 is fixedly connected to the outer wall of the inner support plate 111, and the other end is fixedly fixed to the inner wall of the adjacent outer support plate 111, so as to realize fixed support within a single layer gap.

[0039] In the outer region of the core material 110, the connecting ribs 113 arranged in adjacent connecting gaps 112 are staggered along the circumference of the board surface and are not on the same radial straight line. In the middle region of the core material 110, the connecting ribs 113 in adjacent connecting gaps 112 are arranged both staggered in the circumferential direction and collinear in the circumferential direction.

[0040] This arrangement can interrupt the path of continuous radial stress transmission, allowing the impact load to be continuously dispersed during transmission and reducing the risk of stress fracture.

[0041] Furthermore, based on the staggered arrangement, along the width direction of the connecting gaps 112, at every two connecting gaps 112 with a gap of one, the connecting ribs 113 inside are arranged in a circumferentially aligned position. This design, which alternately staggers adjacent to each other and is relatively aligned at intervals, retains the stress dispersion and deformation resistance advantages brought by the staggered ribs, while using the aligned connecting ribs to construct a stable overall load-bearing skeleton, avoiding the structural looseness defects caused by a completely large-scale staggered arrangement.

[0042] Furthermore, such as Figure 3 and 4 As shown, the handle core material 120 includes a handle frame 121 adapted to the shape of the racket handle, and multiple dividing ribs 122 disposed inside the handle frame 121. The multiple dividing ribs 122 divide the internal space of the handle frame 121 to form a mesh structure. The internal space of traditional racket handles is mostly large-area hollow or simply filled, and the vibration generated by hitting the ball is directly transmitted to the palm along the handle, which can easily cause arm discomfort after holding for a long time. The mesh structure formed by the dividing ribs 122 can block and attenuate vibrations, and further improve the shock absorption effect. Foam material 140 can also be filled inside the mesh structure. At the same time, the mesh structure also improves the torsional stiffness of the handle.

[0043] Furthermore, such as Figure 3 and 4 As shown, a buffer gap 130 is provided between the blade core material 110 and the handle core material 120. This buffer gap 130 is filled with foam material 140, which serves two main purposes: firstly, to block the transmission of vibration from the blade surface to the handle; and secondly, to improve the overall swing elasticity of the racket. The foam material 140 itself has excellent compression and rebound characteristics. When the blade core material 110 vibrates due to impact, the foam layer in the buffer gap 130 acts like a flexible barrier, absorbing most of the high-frequency vibrations and allowing only a small amount of low-frequency vibrations to be transmitted to the handle, resulting in a noticeably softer vibration felt by the player. Simultaneously, the foam material 140 provides additional elastic energy storage and release during the swing, further enhancing the swing elasticity.

[0044] Furthermore, to enhance the elasticity of the shot, both the connection gap 112 and the handle frame 121 can be filled with foam material 140. The foam material 140 can be one of PP foam, PU foam, EVA foam, PMI foam, or epoxy resin foam.

[0045] Furthermore, such as Figure 4As shown, to provide a unified external contour and boundary constraint for the blade core material 110 and the handle core material 120, the blade core 100 also includes an outer frame 150 that adapts to the shape of the racket. Both the blade core material 110 and the handle core material 120 are disposed inside the outer frame 150 and are tightly fitted to the inner wall of the outer frame 150. The outer frame 150 prevents lateral displacement of the blade core material 110 and the handle core material 120 during molding and use, ensuring the integrity of the overall racket structure. The outer frame 150 is made of a material with certain toughness and strength, such as nylon.

[0046] Furthermore, such as Figure 4 and 8 As shown, a edging 160 is also provided on the side of the outer frame 150. The edging 160 extends along the side of the outer frame 150 and covers the outer perimeter of the racket. The main function of the edging 160 is to provide shock absorption and reduce direct damage to the blade core 100 and the outer frame 150.

[0047] The edging 160 specifically includes an outer skin 161 and a filling material 162. The outer skin 161 encloses a semi-closed or closed cavity 163, within which the filling material 162 is housed. The outer skin 161 is made of carbon fiber, and the filling material 162 can be a sponge or foam material 140. When the edge of the racket is impacted, the filling material 162 is first compressed to absorb the impact energy, and then the outer skin 161 evenly distributes the remaining force onto the outer frame 150, effectively reducing local stress concentration and extending the racket's lifespan. Furthermore, the carbon fiber material used for the outer skin 161 improves the racket's side torsional stiffness, making it less prone to deformation.

[0048] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention and should not be construed as limiting the specific implementation of the invention to these descriptions. For those skilled in the art, the architectural form of this invention can be flexibly varied without departing from its conceptual framework, leading to the derivation of a series of products. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
