Description

Technical Field

[0001] This utility model relates to the field of ball sports equipment technology, and more particularly to the field of Peak racket composite fabric technology. Background Technology

[0002] The materials used in Peak rackets typically need to meet the requirements of durability and impact resistance. In the racket manufacturing process, they are usually made of a core material board plus a surface material. The core material is the main part that absorbs impact and provides rebound force, while the surface material is the material that protects the core material and provides surface wear resistance, impact resistance and impact resistance.

[0003] In existing technologies, honeycomb panels or ordinary foam materials are commonly used as core materials to meet the requirements of lightness and strength. However, the existence of existing products requires them to be made relatively thin in order to control quality, which will affect the strength. On the other hand, if high strength is required and the material is thick, it will cause the problem of excessive weight. At the same time, there are requirements for the rebound force of the sweet spot of the core material. For rackets with better quality, it is necessary to use materials with better elasticity and toughness in the sweet spot. However, current products are difficult to meet both requirements at the same time. Therefore, it is necessary to make more optimized improvements and perfections to the materials and design of rackets. Summary of the Invention

[0004] This invention addresses the above problems by proposing a Peak racket with a filled composite core material, which reduces the overall weight, optimizes the product's lightweight design, and improves the racket's hitting effect. Hitting the ball with the sweet spot results in a more substantial impact and a fuller rebound, making it easier for users to hit high-quality returns and providing a better user experience.

[0005] The present invention relates to a Peak racket with a filled composite core material, characterized in that the Peak racket includes a racket plate and a handle, the racket plate and the handle being integrally formed and connected, characterized in that the racket plate includes a face material, a composite core material and a racket frame, wherein the composite core material is inserted into the racket frame, and the face material is covered from both sides of the composite core material and the racket frame to form the racket plate as a whole, the composite core material includes a main plate and a reinforcing composite filler material filled into the main plate.

[0006] The composite core material has filling holes on its main body plate, and the filling holes include one or more, with different filling materials of different densities filling different filling holes.

[0007] The filling hole includes a central sweet spot hole and / or a first hole area, wherein the first hole area is located on the side of the central sweet spot hole away from the handle in the length direction of the racket.

[0008] The filling hole also includes a second hole area and a third hole area, which are located on both sides of the central sweet spot hole in the width direction of the racket, and the second hole area and the third hole area are symmetrical to the central sweet spot hole.

[0009] The filling hole also includes a fourth hole area, which is located on the side of the sweet spot hole in the center of the racket's length direction near the handle.

[0010] The main substrate of the composite core material is foamed polypropylene or polystyrene.

[0011] The foaming ratio of the main body board is 5-40 times, the foaming ratio of the filling material in the central sweet spot is 4-20 times, the foaming ratio of the filling material in the first and fourth hole areas is 3-15 times, and the foaming ratio of the filling material in the second and third hole areas is 3-10 times.

[0012] This utility model relates to a Peak racket with a filled composite core material. By setting filling holes in different areas on the core material and filling it with materials of different densities, a single core material plate can achieve advantages such as light weight, good toughness, high resilience, impact resistance, and good anti-bending properties.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] This utility model relates to a Peak racket with a composite core material, which mainly involves creative innovations in the structure, quality, and performance of the core material. The main material of the core material is still based on foamed polypropylene and polystyrene sheets, which are lightweight and meet the required hardness. To further pursue better hitting performance and feel, holes are drilled in the sheet material, filled with materials of different densities, and then heat-fused together to form a single, integrated sheet.

[0020] Please refer to the attached document. Figure 1 The present invention illustrates a Peak racket with a filled composite core material, the racket comprising a racket blade and a handle, the racket blade 10 and the handle 20 being integrally formed and connected, characterized in that the racket blade 20 comprises a face material 21, a composite core material 22 and a racket frame 23, wherein the composite core material 22 is inserted into the racket frame 23, and the face material 21 is covered from both sides of the composite core material 22 and the racket frame 23 to form the entire racket blade, the composite core material 22 comprising a main body plate 221 and a reinforcing composite filler material 222 filled into the main body plate.

[0021] The composite core material 22 has filling holes 223 on its main plate 221. The filling holes 223 include one or more, and different filling materials 222 with different densities are filled in different filling holes 223.

[0022] The filling hole 223 includes a central sweet spot hole 2231 and / or a first hole area 2232, wherein the first hole area 2232 is located on the side of the central sweet spot hole 2231 away from the handle along the length of the racket. The term "sweet spot" is a common definition in rackets and tennis equipment; it refers to the optimal landing point on the racket for hitting the ball, where the most "sweet" and pleasant sensation is achieved upon impact. Therefore, this area is called the sweet spot.

[0023] Therefore, in this solution, a hole for the sweet spot is pre-set, and this hole is hollowed out to obtain the sweet spot hole. Then, filler material 222 is filled into it.

[0024] To reduce the overall weight of the core material and enhance the racket's anti-rotation properties, i.e., its ability to resist the racket's rotation around its long axis, additional filling holes 223 were constructed, such as the second hole area 2233 and the third hole area 2234.

[0025] The filling hole 223 further includes a second hole area 2233 and a third hole area 2234. The second hole area 2233 and the third hole area 2234 are arranged on both sides of the central sweet spot hole 2231 in the width direction of the racket. The second hole area 2233 and the third hole area 2234 are symmetrical with respect to the central sweet spot hole 2231.

[0026] The filling hole also includes a fourth hole area 2235, which is located on the side of the sweet spot hole 2231 in the center of the racket's length direction near the handle.

[0027] The main body plate 221 of the composite core material 22 is foamed polypropylene or polystyrene.

[0028] The foaming ratio of the main body plate 221 is 5-40 times, the foaming ratio of the filling material 222 in the central sweet area hole 2231 is 4-20 times, the foaming ratio of the filling material 222 in the first hole area 2232 and the fourth hole area 2235 is 3-15 times, and the foaming ratio of the filling material 222 in the second hole area 2233 and the third hole area 2234 is 3-10 times.

[0029] The main body panel needs to be lightweight, with a foaming ratio of 5 to 40 times and low density.

[0030] The second hole area 2233 and the third hole area 2234 need to strengthen the racket's anti-rotation function, that is, the ability to resist the racket's rotation around its long axis. They need to be filled with the densest filling material, with a foaming ratio of 3 to 10 times and the highest density.

[0031] The sweet spot pore 2231 needs to withstand impact and rebound, but it should not be too heavy, so the foaming ratio of the filling material is 4 to 20 times, and the density is the second highest.

[0032] The materials filling the first hole area 2232 and the fourth hole area 2235 can be adjusted according to specific needs, and can be adjusted to high density or low density according to proportion.

[0033] This utility model relates to a Peak racket with a filled composite core material. By setting filling holes in different areas on the core material and filling it with materials of different densities, a single core material plate can achieve advantages such as light weight, good toughness, high resilience, impact resistance, and good anti-bending properties. Moreover, the density of the filling material can be finely adjusted according to specific usage and quality requirements to obtain rackets with different feel and performance effects. The solution is simple, effective, and improves the user experience of the product.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
