Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically to a Peak racket with an EPP core material that enhances the rigidity of the sweet spot. Background Technology

[0002] Expanded polypropylene (EPP) is used in Peak rackets, greatly improving their performance. However, EPP as a core material has some shortcomings: primarily insufficient rigidity, leading to severe deformation of the sweet spot and damage to the overall racket structure after prolonged use. Therefore, rackets using EPP as the core material need to improve their rigidity to meet performance requirements. Utility Model Content

[0003] This invention provides a Peak racket with an EPP core material that enhances the stiffness of the sweet spot, thereby improving racket stiffness, ensuring accuracy and power transfer in shots, and enhancing racket durability.

[0004] A Peak racket with an EPP core material for enhanced sweet spot rigidity has an EPP core material in the inner core and two sides, each side having a non-woven fabric layer and a surface layer in sequence.

[0005] In the sweet spot region, a rigid reinforcement layer is provided between the EPP core material and the nonwoven fabric layer.

[0006] Furthermore, the rigid reinforcement layer is a titanium alloy sheet layer with a thickness of 0.1-0.3 mm.

[0007] Furthermore, the total thickness of the surface layer is 0.1-0.5 mm; it is a carbon fiber layer and a glass fiber layer, or a carbon fiber layer or a glass fiber layer.

[0008] Furthermore, when the surface layer is a carbon fiber layer and a glass fiber layer, the carbon fiber layer is the outer layer; wherein the glass fiber layer accounts for 50%-60% of the total mass of the surface layer.

[0009] The beneficial effects of this utility model are:

[0010] 1. Improved hitting performance: The titanium alloy reinforcement layer in the sweet spot effectively improves the rigidity of this area, reduces racket deformation during hitting, makes hitting more accurate, and transfers power more directly and efficiently, improving the player's hitting experience and competitive level, and meeting the higher requirements of players of different levels for racket performance.

[0011] 2. Enhanced durability: Increased rigidity reduces the risk of racket structural damage due to long-term deformation of the sweet spot under stress, extending the racket's lifespan and reducing the cost of frequent racket replacements.

[0012] 3. Maintain lightweight design: Low-density titanium alloy material is used, which significantly enhances rigidity while keeping the impact on the overall weight of the racket within a small range, maintaining the racket's lightweight advantage and ensuring that the racket's control is not affected.

[0018] The technical solution of this utility model will be further explained and described below through specific embodiments.

[0019] Referring to the attached figures, a Peak racket with an EPP core material has an inner core of EPP core material 1, and on each side, a non-woven fabric layer 2 and a surface layer 3 are sequentially arranged. In the sweet spot area, a rigid reinforcement layer 4 is provided between the EPP core material and the non-woven fabric layer. The rigid reinforcement layer 4 is a titanium alloy sheet layer with a thickness of 0.1-0.3 mm. In this embodiment, the surface layer is composed of a carbon fiber layer 10 and a glass fiber layer 9, with the carbon fiber layer 10 being the outer layer; wherein the glass fiber layer 9 accounts for 50%-60% of the total mass of the surface layer.

[0020] Edge strips 5 are fixed to the edge of the racket head, handle skin 6 is fitted on the outside of the handle, rubber ring 7 is fitted at the joint between the handle and the racket head, and back cover 8 is installed on the back of the handle.

[0021] The Peak racket of this invention was tested and found that the rigidity of the sweet spot was increased by 30%, the hitting accuracy was increased by 20%, and after 1500 consecutive hits, there was no obvious deformation of the sweet spot and no delamination between the layers.
