Problems solved by technology

[0006] (1) For a rigid and soft shaft, due to the large deformation in the middle of the shaft after hitting the ball, the distance between the inflection point of the shaft and the hitting point is longer, the bending angle of the racket face is larger, and the recovery time of the racket face is longer. Long, so the batting speed of the racket is relatively slow. At the same time, if the rebounding speed of the racket line is fast after the racket hits the ball, the shuttlecock will leave the racket surface and fly out. recovery energy;
[0007] (2) With a rigid racket shaft, after the batter hits the ball, the deformation of the middle part of the racket shaft is small. Although the recovery time of the racket surface is relatively fast, due to the rigidity of the racket shaft, the batter's hitting energy It cannot be effectively absorbed by the racket shaft, so the energy storage capacity of the racket shaft is poor. After hitting the ball, the badminton uses the power of the racket shaft to release less energy, resulting in slower hitting speed and poor hitting power.
At the same time, the rigider racket shaft is relatively better in force transmission, so the vibration of the racket after hitting the ball will produce obvious feedback to the batter, which may cause sports injuries to the batter

Abstract

The invention relates to a sports apparatus, in particular to a badminton racket rod and a manufacturing method thereof. The badminton racket rod is in the shape of a hollow cylinder; the hollow cylinder comprises a hollow cylindrical main body, an upper combination body which is closely combined with the outer surface of the hollow cylindrical main body, a middle combination body which is closely combined with the outer surface of the hollow cylindrical main body and a lower combination body which is closely combined with the outer surface of the hollow cylindrical main body, wherein the hollow cylindrical main body, the upper combination body, the middle combination body and the lower combination body are closely combined together so as to form the complete hollow cylinder. According to the manufacturing method of the badminton racket rod, the racket rod is manufactured through two times of molding. At first, a roll core is rolled to from the hollow cylindrical main body; the outer layer of the hollow cylindrical main body is wound with an 0 PP film; the hollow cylindrical main body with the 0 PP film is arranged in a drying oven so as to be subjected to primary molding and curing; the molded and cured hollow cylindrical main body is machined to a structure with a specified diameter; the structure with a specified diameter is wrapped with the middle combination body, the upper combination body and the lower combination body; the outer layer of a structure obtained in the previous step is wound with a 0 PP film; and a tubular piece obtained in the previous step is arranged in the drying oven so as to be subjected to secondary molding and curing; the molded and cured tubular piece is machined to a structure with a specified size.

Description

technical field [0001] The invention relates to a sports equipment, in particular to a badminton racket shaft and a manufacturing method thereof. Background technique [0002] Badminton is a wide range of sports. For users, it is very important to use a good badminton racket in sports. If you use a bad racket, it will affect the user's feeling and mood. The impact is great, and it may even cause sports injuries, but what kind of racket is considered a good racket? A racket with fast speed, high stability, good power transmission, and low vibration is a good racket. The industry has been devoting itself to designing and manufacturing a kind of good badminton racket to adapt to the needs of users and badminton. [0003] The existing badminton racket shaft (also known as the middle tube) generally adopts a hollow cylinder in shape. When designing and manufacturing, the hollow cylinder adopts the same material combination in the length direction, and the wall thickness of the ...
