Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically to a Peak racket with a PP honeycomb core material for enhanced sweet spot rigidity. Background Technology

[0002] With the growing popularity of peakball, the demands on peak racket performance are becoming increasingly stringent. Traditional rackets with polypropylene (PP) honeycomb cores have significant drawbacks. Upon impact, the PP honeycomb core is prone to deformation, causing the sweet spot (hitting area) to dent over time, severely impacting hitting performance and racket lifespan. This not only alters the ball's bounce trajectory and power transfer, reducing the player's hitting precision, but also easily leads to delamination failure, increasing user costs and replacement frequency. Therefore, there is an urgent need to improve the sweet spot rigidity of PP honeycomb core rackets to enhance their overall performance. Utility Model Content

[0003] This invention provides a Peak racket with a PP honeycomb core material that enhances the rigidity of the sweet spot, in order to improve the performance of the Peak racket.

[0004] A Peak racket with a sweet spot reinforced rigidity using PP honeycomb core material, the inner core being PP honeycomb core material, with a non-woven fabric layer and a surface layer sequentially arranged on each side;

[0005] In PP honeycomb core material, a rigid support is embedded in the PP tube in the sweet spot. The rigid support is a bead or a column.

[0006] Furthermore, edge strips are fixed to the edge of the racket head, a handle skin is fitted over the handle, a rubber ring is fitted at the joint between the handle and the racket head, and a back cover is installed on the back of the handle.

[0007] Furthermore, in the PP honeycomb core material, the PP tubes are covered with POE film, and adjacent PP tubes are fused together by the POE film.

[0008] Furthermore, the rigid support member is made of metal or plastic.

[0009] Furthermore, the number of rigid support components installed is 60%-80% of the total number of PP pipes in the sweet spot area.

[0010] Furthermore, the rigid support is fixed in the PP pipe by a high-strength adhesive.

[0011] Furthermore, the total thickness of the surface layer is 0.1-0.5 mm; it is a carbon fiber layer and / or a glass fiber layer.

[0012] Furthermore, when the surface layer is a carbon fiber layer and a glass fiber layer, the glass fiber layer accounts for 50%-60% of the total mass of the surface layer; and the glass fiber layer is the outer layer.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, by adding a rigid support to the sweet spot, the rigidity of the sweet spot is significantly enhanced, effectively reducing the degree of deformation of the sweet spot when hitting the ball, making the shot more accurate, the power transmission more direct and efficient, bringing a better hitting experience to the player, and meeting the needs of players of different levels for high-quality rackets.

[0015] 2. The increased stiffness of the sweet spot greatly reduces racket deformation caused by long-term hitting, extending the racket's lifespan and reducing the frequency of replacement, thus saving costs for users.

[0016] 3. Compared with using expensive new materials to comprehensively improve rigidity, this utility model adds beads or columns to the PP tube in the sweet spot area, which effectively improves performance while better controlling costs. The lower cost is conducive to the promotion of the product in the market. Attached Figure Description

[0023] The technical solution of this utility model will be further explained and described below through specific embodiments.

[0024] Example 1

[0025] Referring to the attached drawings, this utility model provides a Peak racket with a PP honeycomb core material. The inner core is a PP honeycomb core material 1, and on both sides, a non-woven fabric layer 2 and a surface layer 3 are arranged sequentially on each side. An edge strip 8 is also fixed on the edge of the racket head. A handle skin 9 is fitted on the outside of the handle. A rubber ring 10 is fitted at the connection between the handle and the racket head. A back cover 11 is also installed on the rear side of the handle.

[0026] In PP honeycomb core material 1, PP tubes are covered with POE film, and adjacent PP tubes are fused together using the POE film. Rigid supports are embedded in the PP tubes within the sweet spot area. These rigid supports are fixed to the PP tubes with a high-strength adhesive. The rigid supports are steel balls 4, steel columns 5, plastic beads 4, or plastic columns 5. The rigid supports cover 60%-80% of the sweet spot area.

[0027] The surface layer 3 consists of a carbon fiber layer 6 and a glass fiber layer 7. The carbon fiber layer 6 is a molded sheet of epoxy carbon fiber prepreg with a thickness of 0.1-0.5 mm, and the glass fiber layer 7 is composed of an epoxy glass fiber semi-cured sheet with a thickness of 0.1-0.5 mm. The glass fiber layer 7 accounts for 50%-60% of the total mass of the surface layer 3 and is the outer layer.

[0028] In this embodiment, the carbon fiber layer 6 is 0.3 mm thick, the glass fiber layer 7 is 0.2 mm thick, the molded surface layer 3 is 0.5 mm thick, and the glass fiber layer 7 accounts for 55% of the total mass of the surface layer 3.

[0029] Example 2

[0030] In this embodiment, the surface layer 3 is a carbon fiber layer 6 with a thickness of 0.1 mm.

[0031] Example 3

[0032] In this embodiment, the surface layer 3 is a glass fiber layer 7 with a thickness of 0.2 mm.

[0033] A comparative experiment was conducted between the Peak racket manufactured according to this invention and a Peak racket with ordinary PP honeycomb core material. The ordinary racket showed a significant 3mm indentation deformation in the sweet spot when the pressure reached 50N; while the racket manufactured according to this invention only showed a 1mm indentation deformation when the pressure reached 80N, fully demonstrating the significant effect of the sweet spot reinforcement structure on improving rigidity. After 800 consecutive hits, the ordinary racket showed obvious deformation and wear in the sweet spot, with some areas beginning to show signs of delamination; while the racket manufactured according to this invention showed only slight wear in the sweet spot after 1500 consecutive hits, with the overall structure remaining intact, strongly demonstrating the positive effect of the sweet spot reinforcement structure on improving racket durability.
