Background technique

Pickleball is a racket-type sport that combines the characteristics of badminton, tennis and billiards. The size of the pickleball court is similar to that of a badminton court. For billiard rackets, the sphere of a pickle is a hollow plastic ball that is slightly larger than a tennis ball and has multiple holes. The play of the pickle is similar to that of tennis. It can hit the ball on the ground or volley directly in the air. This kind of pickleball sports has established a good reputation after millions of people around the world in recent years. Undoubtedly, it is a fun, easy-to-follow and trendy sport suitable for all ages.

The racket core is the backbone of any Pickle racket, among which, in order to have sufficient strength for effective hitting, the current racket core mainly adopts aluminum core or polypropylene (PP) core with honeycomb structure; and for cushioning control and For a quieter shot, another racquet core uses a foamed polymer material. However, in actual use, the racket core with honeycomb structure is likely to generate a drum-like noise when the user hits the ball. Although the racket core of foamed polymer has the functions of buffering and noise reduction, it will Insufficient strength and the need to increase the thickness of the racket makes the pick racket bulky and unfavorable for operation.

The first panel and the second panel are respectively formed by bonding and curing at least one fiber cloth; and

The racket core includes a first buffer layer, a second buffer layer and a polymethacrylimide solid core board, the lower board surface of the first panel is combined with the first buffer layer, the second panel is The upper board surface is combined with the second buffer layer, and the polymethacryimide solid core board is combined between the first buffer layer and the second buffer layer.

During implementation, the first panel includes two first fiber cloths of different materials, and the two first fiber cloths of the first panel are stacked and bonded to each other.

During implementation, the two first fiber cloths of the first panel are respectively a carbon fiber cloth and a glass fiber cloth.

During implementation, the second panel includes two second fiber cloths of different materials, and the two second fiber cloths of the second panel are stacked and bonded to each other.

During implementation, the two second fiber cloths of the second panel are respectively a carbon fiber cloth and a glass fiber cloth.

During implementation, the first buffer layer is a polyvinyl butyral resin film.

During implementation, the second buffer layer is a polyvinyl butyral resin film.

The utility model has the advantages of providing a Pickle racket structure, which can generate sufficient hitting strength and reduce the Noise effect, and reduce the overall thickness of the Pickle racket to facilitate the user's control.

In order to have a more in-depth understanding of the present utility model, it is described in detail later.

Detailed ways

The pick racket structure of the utility model has a reversed first panel and a second panel, the first panel and the second panel are respectively formed by bonding and hardening at least one fiber cloth; the lower panel surface of the first panel and the upper panel surface of the second panel are A racket core is sandwiched and glued on top of the board. The racket core comprises a first buffer layer, a second buffer layer and a polymethacrylimide solid core board, the lower surface of the first panel is combined with the first buffer layer, and the upper surface of the second panel is combined with the second buffer layer, And a polymethacrylimide (PMI) solid core board is combined between the first buffer layer and the second buffer layer.

Please refer to FIG. 1 and FIG. 2 , which is a preferred embodiment of the Pickle racket structure 1 of the present invention, which mainly includes a first panel 2 , a second panel 3 , a first buffer layer 4 , and a second buffer Layer 5 and a polymethacrylimide (Polymethacrylimide, PMI) solid core board 6 . The first buffer layer 4 , the second buffer layer 5 and the PMI solid core board 6 are combined into a racket core 7 , and the racket core 7 is sandwiched and bonded to the lower surface 21 of the first panel 2 and the second panel 3 Between the upper plate surfaces 31 of the first and second panels 2 and 3 , the upper and lower sides of the first panel 2 and the second panel 3 are opposite to the two ends of the racket core 7 .

The first panel 2 includes two first fiber cloths (22, 23) of different materials, and the two first fiber cloths (22, 23) are respectively at least one carbon fiber cloth disposed on the outer layer and at least one carbon fiber cloth disposed on the inner layer. Glass fiber cloth, each carbon fiber cloth includes a plurality of woven carbon fibers. After the carbon fiber cloth is cured by resin bonding, the carbon fibers of the carbon fiber cloth cross each other to produce high rigidity; and each glass fiber cloth includes a plurality of woven glass fibers , After the glass fiber cloth is cured by resin bonding, the individual glass fibers of the glass fiber cloth cross each other to produce high toughness strength.
