Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A shock-absorbing and noise-reducing ab wheel includes a control structure 1, and a movable structure 2 is fixedly connected to the outer wall of the control structure 1. The control structure 1 includes a fixed shell 11, a fixed cover 12, a connecting rod 13, two rotating parts 14, two fixed rods 15, and two protective sleeves 16. The top of the fixed shell 11 is bolted to the bottom of the fixed cover 12. The inner wall of the fixed shell 11 is rotatably connected to the outer wall of the connecting rod 13. The outer wall of the fixed cover 12 is rotatably connected to the inner wall of the connecting rod 13. The left side of the connecting rod 13 is fixedly connected to the right side of the rotating part 14. The front side of the rotating part 14 is fixedly connected to the rear side of the fixed rod 15. The outer wall of the fixed rod 15 is bonded to the inner wall of the protective sleeve 16.

[0019] In this embodiment: By setting up a control structure 1, in which the fixed shell 11 and the fixed cover 12 together constitute the main frame of the control structure 1, a stable rotational support is provided for the connecting rod 13. At the same time, the structural rigidity reduces vibration transmission and protects the internal rotating parts. The connecting rod 13 is the core component connecting the rotating part 14 and the main body of the control structure 1. Its smooth rotational mating surface is used to reduce frictional resistance during rotation. The rotating part 14 adopts a design that can be closed and unfolded. It can be unfolded when the user is using it and closed when not using it, reducing the overall accommodation space of the ab wheel. The fixed rod 15 and the protective sleeve 16 are provided. The fixed rod 15 provides rigid support for the user's grip, while the protective sleeve 16 is made of flexible material to buffer the pressure of the hand when gripping, reduce vibration transmission between the hand and the rod, reduce frictional noise when gripping, and improve the comfort of use.

[0020] Specifically, such as Figure 3 , Figure 4 , Figure 5As shown, the movable structure 2 includes a fixed frame 21, the inner side of which is fixedly connected to the outer side of the fixed shell 11.

[0021] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a rotating column 22 is rotatably connected to the inner wall of the fixed frame 21, and mounting wheels 23 are bolted to both sides of the rotating column 22.

[0022] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a movable column 24 is rotatably connected to the inner wall of the fixed frame 21, and connecting wheels 25 are bolted to both sides of the movable column 24.

[0023] In this embodiment: By setting up a movable structure 2, in which the fixed frame 21 adopts a wide design, the support width between the wheel body and the ground is increased, the pressure of the ab wheel body is distributed, and the swaying and vibration caused by the unstable center of gravity during use are reduced, thereby reducing the noise generated by vibration transmission. The rotating column 22 and the mounting wheel 23 are set up. The rotating column 22 is designed as a thick column. The thick column structure of the rotating column 22 has stronger rigidity, which can reduce deformation during rotation and reduce the vibration caused by the bending of the column body. By reducing the vibration amplitude, the shock absorption effect is achieved, making the contact between the mounting wheel 23 and the ground more stable and the rolling friction more uniform, reducing the noise generated by the wheel body jumping. The movable column 24 and the connecting wheel 25 are set up. The movable column 24 is smaller than the rotating column 22. The smaller movable column 24 and the connecting wheel 25 can serve as auxiliary support, forming a main and auxiliary wheel system structure with the mounting wheel 23. This can reduce the overall rotational inertia, reduce the rigid collision when in contact with the ground, and further improve the rolling stability with the mounting wheel 23, thereby reducing the overall noise.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a connecting shell 3 is fixedly connected to the rear side of the rotating part 14, and a connecting part 4 is fixedly connected to the left side of the rotating part 14. There are two connecting shells 3 and two connecting parts 4.

[0025] Specifically, such as Figure 3 As shown, a mounting hole 5 is provided on the rear side of the left side of the fixing frame 21, and the inner wall of the mounting hole 5 is rotatably connected to the outer wall of the rotating column 22.

[0026] Specifically, such as Figure 3 As shown, a mating hole 6 is provided on the front side of the left side of the fixed frame 21, and the inner wall of the mating hole 6 is rotatably connected to the outer wall of the movable column 24.

[0027] In this embodiment: by setting a connecting shell 3 and a connecting piece 4, when the rotating part 14 is unfolded, the connecting piece 4 is simultaneously inserted into the inner side of the connecting shell 3. The user can use bolt threads to pass through the connecting shell 3 and the connecting piece 4 to prevent the rotating part 14 from moving freely. By setting the mounting hole 5 and the mating hole 6 respectively opened by the fixing bracket 21, both provide rotation holes for the rotating column 22 and the movable column 24, ensuring the coaxiality of the wheel when it rolls, reducing frictional vibration and noise caused by shaft offset, and the smooth processing ability of the hole wall can reduce the frictional resistance when the column rotates, indirectly reducing frictional noise.

[0028] Specifically, such as Figure 4 As shown, the outer wall of the protective sleeve 16 is provided with anti-slip texture, the two rotating parts 14 are respectively disposed on both sides of the connecting rod 13, and the two protective sleeves 16 are respectively disposed on the outer wall of the two fixed rods 15.

[0029] In this embodiment, the protective sleeve 16 is made of rubber material and has anti-slip texture on the outer wall to increase the friction when using the gripping rod 15 and increase the stability of use.

[0030] Working principle: This shock-absorbing and noise-reducing ab wheel achieves stable operation through the coordinated operation of control structure 1 and moving structure 2. In control structure 1, the fixed shell 11 and fixed cover 12 form the main frame, providing rotational support for the connecting rod 13. The connecting rod 13 connects to the rotating parts 14 on both sides through a smooth rotating surface, reducing frictional resistance. When in use, the rotating parts 14 are unfolded, and the connecting parts 4 are inserted into the connecting shell 3 and fixed by screws to prevent shaking. When not in use, the wheel is closed to reduce storage space, the fixed rod 15 provides grip support, and the rubber protective sleeve 16 increases grip through anti-slip texture. Friction is mitigated by flexible materials that buffer vibration and noise. The fixed frame 21 of the movable structure 2 adopts a wide design, supporting the rotating column 22 and the movable column 24 through the mounting hole 5 and the mating hole 6 respectively. The rotating column 22 is a thick column structure with high rigidity and small deformation, driving the mounting wheel 23 to roll smoothly. The movable column 24 and the connecting wheel 25 serve as auxiliary supports, forming a main and auxiliary wheel system to reduce rotational inertia. When the wheel rolls, the fixed frame 21 distributes pressure to reduce swaying. The smooth fit between the column and the hole wall reduces friction and vibration, ensuring stability and comfort during use.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
