Description

Technical Field

[0001] The present invention relates to the technical field of sports goods, in particular to a double-elastic badminton racket. Background Art

[0002] In badminton, racket performance significantly impacts the effectiveness of a shot. Most badminton rackets currently on the market suffer from insufficient hitting power and limited tactics due to a single power source, making them difficult to meet the diverse needs of athletes. Furthermore, some rackets lack stability during the swing, impacting accuracy and power delivery. Therefore, there is an urgent need for a badminton racket that can enhance hitting power, improve swing stability, and provide variable power. Summary of the Invention

[0003] The purpose of the present invention is to provide a double-elastic badminton racket, which has the characteristics of being able to provide greater hitting power, relatively stable hitting, and being able to adjust the power according to tactical needs.

[0004] The technical solution adopted by the present invention is: a double-elastic badminton racket, including a ball frame and a ball shaft with an upper end fixedly connected to the lower end of the ball frame; the ball frame is provided with a ball net, which is divided into a windward side for hitting the ball and a leeward side opposite to the windward side; two side surfaces of the upper part of the ball shaft corresponding to the windward side and the leeward side are respectively provided with a windward convex ridge and a leeward convex ridge; at the same time, at least three "V"-shaped notches are distributed from top to bottom on the leeward convex ridge.

[0005] Seen from the side, the windward convex ridge and the leeward convex ridge are both arc-shaped, and the height of the highest point is 1-3 mm.

[0006] The opening angle of the "V"-shaped notch is 45-60 degrees, and the interval between two adjacent "V"-shaped notches is 8-12 mm.

[0007] From top to bottom, the distance between two adjacent "V"-shaped notches gradually increases.

[0008] The upper end portion of the ball frame is provided with at least two weight-increasing columns.

[0009] The upper end portion of the ball frame is provided with at least two screw holes with openings facing downwards, and the weight-increasing columns are screwed into the corresponding screw holes.

[0010] Each weighted column weighs 3-5g.

[0011] The net is divided into two layers of nets, one serving as the windward side and the other as the leeward side. The initial tension and the net density of the one layer of net serving as the windward side are greater than those of the one layer of net serving as the leeward side.

[0012] The golf club is made of carbon fiber material.

[0013] The advantages of the present invention over the prior art include: greater hitting power, more stable hitting, and the ability to adjust the force according to tactical needs. The dual-elastic badminton racket of the present invention utilizes the characteristic that the shaft bends to a certain extent during the swing process. By providing a "V"-shaped notch and weighted columns, the weighted points at the upper end of the racket frame impart a forward force due to inertia at the moment of impact, while the shaft instantly returns to a straight state. This elastic deformation recovery and the inertial effect of the weighted points make the shot more powerful. In particular, the ridges on the shaft enhance the structural strength of the shaft, while the "V"-shaped notch on the ridge on the leeward side significantly affects the elastic deformation of the shaft during the bending and recovery process, further optimizing the transmission and release of force. Furthermore, when changing tactics, players can adopt leeward hitting and appropriately add or remove weighted columns, allowing them to employ a variety of offensive tactics at any time.

[0023] In the following embodiments, the terms such as windward side and leeward side are introduced only for the convenience of explanation and have no substantial meaning or definition.

[0024] For example, see Figures 1 to 6The figure shows a double-elastic badminton racket, comprising a frame 10 and a shaft 20, the upper end of which is fixedly connected to the lower end of the frame 10. The shaft 20 is made of carbon fiber. A net 30 is mounted on the frame 10. For ease of illustration, the net 30 is divided into a windward side 31 for hitting the ball and a leeward side 32 opposite the windward side 31. Obviously, athletes can use the leeward side 32 to hit the ball.

[0025] Further speaking:

[0026] The upper portion of the racket 20 is provided with a windward ridge 21 and a leeward ridge 22 on two side surfaces corresponding to the windward side 31 and the leeward side 32, respectively. Furthermore, the leeward ridge 22 is provided with at least three V-shaped notches 221 distributed from top to bottom. This allows the racket 20 to bend backwards with a relatively large degree of deflection at the V-shaped notches 221 when hitting the ball from the windward side 31. At the moment of impact, the racket 20 quickly returns to its original position, exerting greater force on the shuttlecock. Conversely, when hitting the ball from the leeward side 32, the racket 20 bends less, resulting in a relatively weaker impact. This means that the racket of the present invention not only provides greater impact force, but also allows for slight variations in impact force, which are highly sensitive to players. Furthermore, the introduction of the ridges makes the upper portion of the racket more stable, resulting in a more stable impact due to inertia.

[0027] Optimized:

[0028] Viewed from the side, the windward ridge 21 and the leeward ridge 22 are both arc-shaped, with a higher center and lower ends. The height of the highest point in the center is 1-3 mm, for example, 1, 2, or 3 mm. The opening angle of the "V"-shaped notch 221 is 45-60°, for example, 45, 55, or 60°. The spacing between two adjacent "V"-shaped notches 221 is 8-12 mm, for example, 8, 10, or 12 mm. Simultaneously, the spacing between two adjacent "V"-shaped notches 221 gradually increases from top to bottom. Practical verification has shown that using the aforementioned parameters results in a more balanced overall performance for badminton rackets, gaining recognition from a relatively greater number of athletes. Finite element analysis simulating the swing process shows that the presence of the V-shaped notch significantly changes the stress distribution and bending recovery characteristics of the leeward side of the club. In particular, when combined with the weighted column described below, the racket's instantaneous recovery speed after hitting the ball is faster and the effect is better. Comparative tests show that at the same swing speed, when hitting the ball with the windward side of the racket of the present invention, the ball release speed is increased by an average of 10% compared to conventional rackets.

[0029] In another embodiment:

[0030] The upper end of the ball frame 10 is provided with at least two weighted columns 12. These weighted columns 12 can be integrally formed with the ball frame 10. Alternatively, the upper end of the ball frame 10 is provided with at least two screw holes 11 with openings facing downward, and the weighted columns 12 are screwed into the corresponding screw holes 11. Each weighted column 12 weighs 3-5g, for example, 3, 4, or 5g; the weights of the weighted columns 12 can be different. In this way, different numbers of weighted columns 12 or weighted columns 12 of different weights can be selected at any time as needed, making the athlete's tactics more flexible.

[0031] In another embodiment:

[0032] The net 30 is divided into two layers, one serving as the windward side 31 and the other as the leeward side 32. Specifically, the net 30 is comprised of two parallel layers, and the initial tension and mesh density of the layer serving as the windward side 31 are greater than those of the layer serving as the leeward side 32. This allows for different hitting forces when hitting the ball using either the windward side 31 or the leeward side 32.

[0033] It's important to note that the use of weighted posts can be combined with the specific hitting surface. For example, adding weight and hitting the ball from the windward side can yield a relatively stronger hitting force, while reducing weight and hitting the ball from the leeward side can yield a relatively weaker hitting force, suitable for front-row players in doubles. Different weighting combinations and different hitting surfaces can create a variety of intermediate states, allowing users to develop a routine based on their needs.

[0034] In summary, the dual-elastic badminton racket of the present invention not only provides greater and more stable hitting force during the stroke, but also allows for leeward hitting, as well as the appropriate addition or removal of weighted columns, allowing athletes to employ a wider range of offensive tactics at any time. The foregoing description is merely a preferred embodiment of the present invention and does not limit the scope of the present invention. Any equivalent structure or equivalent process variation based on the present specification and drawings, or any direct or indirect application in other related technical fields, is equally encompassed within the scope of the present invention.
