Description

Technical Field

[0001] This utility model belongs to the field of sports equipment technology, specifically relating to a lightweight exoskeleton-enhanced badminton racket. Background Technology

[0002] Existing wind-driven frame technologies are mostly used in wind-driven badminton rackets. The underlying logic of this technology is to create holes in the frame to achieve a flow-through effect. However, a drawback of this technology is that the holes in the frame can make it less stable and prone to breakage upon impact. In addition, existing technologies also employ multi-whip-gain systems for the shaft, often used in some mid-to-high-end badminton rackets. The underlying logic of this technology is to use varying stiffness in the shaft to make it more prone to deformation upon impact. However, a drawback of this technology is that the use of different stiffness configurations in the shaft results in an unstable gain effect, making it difficult to achieve consistent control within a fixed range.

[0003] To address the aforementioned deficiencies, the applicant filed a utility model patent application on October 14, 2024, entitled "A Badminton Racket with Enhanced External Rigidity," application number 202422487285.8. This utility model patent incorporates corresponding raised threads on both the racket frame and the connecting rod, enabling the racket frame to achieve both aerodynamic guidance and strong stability during the swing. Similarly, the raised threads on the connecting rod, while providing the effect of varying shaft stiffness, make it easier to deform upon impact, thus facilitating a more energy-efficient swing.

[0004] However, the present invention has the following problems in actual application: threaded protrusions are set on the entire frame and connecting rod, which increases the overall weight of the racket, increases the load on the user, and reduces the swing speed, thus reducing the player's instantaneous explosive power when smashing. Utility Model Content

[0005] In order to solve the problem that the existing technology, with its threaded protrusions covering the entire frame, leads to an increase in frame weight and a reduction in swing speed, the purpose of this utility model is to provide a lightweight exoskeleton-enhanced badminton racket.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A lightweight exoskeleton-enhanced badminton racket includes a frame, a connecting rod, and a grip. The frame has threaded protrusions on the top and sides. The connecting rod is connected to the bottom of the frame. The grip is installed on the end of the connecting rod away from the frame. The line connecting the distribution edge of the threaded protrusions on the top of the frame to the geometric center of the frame has an acute angle b. The line connecting the distribution edge of the threaded protrusions on the sides of the frame to the geometric center of the frame has an acute angle a.

[0008] Optionally, threaded protrusions are symmetrically distributed on both sides of the top of the frame.

[0009] Alternatively, the included angle α can be 30° to 60°.

[0010] Alternatively, the included angle b can be 30° to 60°.

[0011] Optionally, the inner ring of the racket frame is provided with multiple net connectors, which are evenly distributed on the inner ring of the racket frame.

[0012] Alternatively, the threaded protrusions are spirally distributed on the frame, and the threaded protrusions on the front and back of the frame are intermittently arranged.

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

[0014] This invention provides a lightweight exoskeleton-reinforced badminton racket. By incorporating threaded protrusions on the top and sides of the frame, with the edges of these protrusions forming angles 'b' and 'a' with the geometric center of the frame, respectively (both angles 'a' and 'b' being acute), the threaded protrusions are reduced to only appear at the 3 o'clock, 9 o'clock, and 12 o'clock positions on the frame plane. This reduces the overall weight of the racket, increasing the player's swing speed and allowing for a more explosive smash. Furthermore, the top and sides, being the ends of the racket, experience the greatest stress and are most vulnerable to damage, potentially leading to deformation or breakage. The threaded protrusions at the 3 o'clock, 9 o'clock, and 12 o'clock positions reinforce these vulnerable areas, increasing the racket's strength and thus its lifespan. Attached Figure Description

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] Reference Figures 1-4 A lightweight exoskeleton-enhanced badminton racket includes a grip 1, a connecting rod 2, and a frame 3; the frame 3 has threaded protrusions 4 on the top and sides; the connecting rod 2 is connected to the bottom of the frame 3; the grip 1 is installed on the end of the connecting rod 2 away from the frame 3, and the connecting rod 1 and the frame 3 are connected by a T-shaped head 6.

[0023] like Figure 4 As shown, the line connecting the distribution edge of the threaded protrusion 4 at the top of the frame 3 and the geometric center of the frame 3 has an acute angle b; the line connecting the distribution edge of the threaded protrusion 4 on both sides of the frame 3 and the geometric center of the frame 3 has an acute angle a. By setting threaded protrusions 4 on the top and sides of the frame 3, and the lines connecting the distribution edges of the threaded protrusions 4 to the geometric center of the frame 1 form angles b and a, respectively, both angles a and b being acute angles, the threaded protrusions 4 on the plane of the frame 3 only exist at the three o'clock, nine o'clock, and twelve o'clock positions. This reduces the distribution of threaded protrusions 4 on the racket, thereby reducing the overall weight of the racket and increasing the player's swing speed, allowing the player to feel the instantaneous explosive power when smashing. When the player swings the racket, the top and sides, as the ends, are the parts that bear the greatest force and are also the parts of the racket most easily damaged, resulting in deformation or breakage. The threaded protrusions 4 set at the three o'clock, nine o'clock, and twelve o'clock positions on the plane of the frame 3 in this utility model strengthen the most vulnerable parts of the frame 3, increasing the strength of the frame 3 and thus increasing the service life of the racket.

[0024] Establish as Figure 4 In the coordinate system shown, the intersection of the two axes of symmetry of the ball frame 3 plane in the vertical and horizontal directions is the geometric center of the frame 3. The fan-shaped region formed from the geometric center of the frame 3 along the acute angle b is mirror-symmetrical along the vertical axis of symmetry; the fan-shaped regions formed from the geometric center of the frame 3 to both sides along the acute angle a are mirror-symmetrical along the horizontal axis of symmetry. This results in the threaded protrusions 4 at the top being symmetrically distributed on both sides of the top of the frame 3.

[0025] Specifically, the included angle α is 30° to 60°, preferably 40°. The included angle β is 30° to 60°, preferably 40°.

[0026] When both angles a and b are 30°, while reinforcing the most vulnerable part of the frame 3, the area covered by the threaded protrusion 4 on the frame 3 is about 1 / 4 of the entire frame 3.

[0027] When both angles a and b are 40°, while reinforcing the most vulnerable part of the frame 3, the area covered by the threaded protrusion 4 on the frame 3 is about 1 / 3 of the entire frame 3.

[0028] When both angles a and b are 60°, while reinforcing the most vulnerable part of the frame 3, the area covered by the threaded protrusion 4 on the frame 3 is about 1 / 2 of the entire frame 3.

[0029] The threaded protrusions 4 can be distributed in any of the three ways mentioned above. Compared with the existing case where the threaded protrusions 4 cover the entire frame 3, the weight is lower. Even when the included angles a and b are both 30°, the threaded protrusions 4 can still cover the three o'clock, nine o'clock and twelve o'clock directions on the plane of the frame 3.

[0030] In this embodiment, the inner circle of the racket frame 3 is provided with a plurality of wire mesh connectors 5, which are evenly distributed on the inner circle of the racket frame 3.

[0031] In this embodiment, as Figure 3 As shown, the threaded protrusions 4 are spirally distributed on the frame 3, and the threaded protrusions 4 on the front and back of the frame 3 are intermittently arranged. That is, the threaded protrusions 4 on the frame 3 are not a complete spiral line, but only on the front and back. The intermittent threaded protrusions 4 give the surface of the frame 3 a streamlined shape, which can effectively guide airflow, reduce air resistance, and thus improve the swing speed and the efficiency of continuous hitting.
