Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fitness equipment, and in particular to a damped folding fitness device. Background Technology
[0002] With the popularization of home fitness equipment, resistance bands have gradually become a common home fitness device due to their advantages such as flexible exercise modes and small footprint. For example, some resistance bands use dual motors on both sides to pull the training rope connected to the resistance device through the pull component to achieve the purpose of exercise. They are suitable for ordinary families. However, the structure of such resistance bands is relatively complex and difficult to fold and store, taking up a lot of space, which urgently needs to be addressed.
[0003] For example, Chinese patent CN219462424U provides a flat-panel intelligent strength trainer, including a flat panel. The bottom surface of the flat panel is a first support surface, and a motor compartment is connected to the first side of the flat panel. The top surface of the motor compartment protrudes relative to the top surface of the flat panel, and the outer side of the motor compartment is a second support surface. When the trainer is in use, the first support surface contacts the ground; when the trainer is in storage, the second support surface contacts the ground. This strength trainer is stored vertically with the second support surface in contact with the ground. However, the second support surface houses components such as a motor, making it relatively heavy. If the top of the trainer is accidentally bumped and not against a wall, it is still prone to tipping over. Furthermore, this trainer cannot be folded for storage, taking up a significant amount of space. Utility Model Content
[0004] To address the shortcomings of the prior art, this application provides a damped folding fitness device.
[0005] The above-mentioned inventive objective of this application is achieved through the following technical solutions:
[0006] A damped folding fitness device includes a shell and a rotating shaft. Two shells are symmetrically arranged and are respectively located at opposite ends of the rotating shaft. The rotating shaft contains a first rotating shaft and a second rotating shaft. Each shell has a rotating component with a rotating hole. The rotating components of both shells pass through the rotating holes and engage with the first and second rotating shafts to achieve a rotatable connection. Several protrusions are arranged along the circumference of the outer edge of the rotating component. An elastic block is provided inside the rotating shaft. During the rotation of the rotating component, the protrusions abut against the elastic block one by one.
[0007] Preferably, the rotating part has an arc-shaped limiting hole, and the rotating shaft part has a limiting slider, which slides in the arc-shaped limiting hole.
[0008] Preferably, the two ends of the rotating shaft are provided with arc-shaped clearance openings corresponding to the connection with the outer shell. The arc-shaped clearance holes are used to provide the rotating component with a movable position to drive the outer shell to rotate.
[0009] Preferably, both the outer edge of the protrusion and the outer edge of the elastic block have a rounded transition.
[0010] Preferably, the top of the rotating shaft has an installation opening, an elastic sheet is provided inside the installation opening, and an elastic block is provided at the bottom of the elastic sheet and located inside the rotating shaft.
[0011] Preferably, the rotating shaft includes a first mounting base and a second mounting base. The first mounting base is provided with a first mounting sleeve and a first insertion shaft, and the second mounting base is provided with a second mounting sleeve and a second insertion shaft. The first mounting sleeve and the second insertion shaft are inserted and engaged to form a first rotating shaft, and the second mounting sleeve and the first insertion shaft are inserted and engaged to form a second rotating shaft.
[0012] Preferably, the number of elastic blocks is set to four, with two elastic blocks disposed inside the first mounting base and the other two elastic blocks disposed inside the second mounting base. Each housing is provided with two rotating parts, and the protrusions of the two rotating parts of each housing correspond to the two elastic blocks of the first mounting base and the second mounting base, respectively.
[0013] Preferably, when the first mounting sleeve and the second insertion shaft are engaged, and when the second mounting sleeve and the first insertion shaft are engaged, the first mounting base and the second mounting base are connected by a male-female groove structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the cooperative structure of the pivot and rotating components, the symmetrically arranged outer shell can rotate around the first and second pivot axes to achieve folding. After folding, the size of the fitness equipment is significantly reduced, adapting to the need for storage in confined spaces. Simultaneously, during the rotation and folding process, the successive contact between the protrusions and elastic blocks on the rotating component creates a damping effect, preventing swaying due to inertia during shell rotation, reducing component collision damage, and facilitating control of the rotation amplitude, thus improving user convenience. The cooperation between the arc-shaped limiting hole and the limiting slider, as well as the setting of the arc-shaped clearance opening, further enhances… The rotation angle is limited to prevent excessive rotation from causing structural damage. Furthermore, the symmetrical double-shell structure, with the pivot component using a symmetrical structure consisting of a first mounting base and a second mounting base, ensures even weight distribution after folding and a compact overall structure, reducing the risk of tipping due to accidental contact. Additionally, the pivot component's quick assembly is facilitated by the interlocking of the first and second mounting bases and the positioning via male and female grooves. The rounded transition design of the protrusions and elastic blocks reduces friction loss, and the corresponding arrangement of multiple sets of elastic blocks and rotating components results in more uniform damping, thus improving the user experience.

[0024] The following is a reference appendix. Figure 1 To be continued Figure 5 This application describes a damped folding fitness device.
[0025] Reference Figures 1 to 5 The damping folding fitness device includes a shell 1 and a pivot 2. Two shells 1 are symmetrically arranged, located at opposite ends of the pivot 2. The pivot 2 contains a first pivot 3 and a second pivot 4. Each shell 1 has a rotating component 5 with a rotating hole 6. The rotating components 5 of both shells 1 pass through the rotating holes 6 and engage with the first pivot 3 and the second pivot 4 to achieve a rotatable connection. Several protrusions 7 are arranged along the circumference of the outer edge of the rotating component 5. An elastic block 8 is located inside the pivot 2. During the rotation of the rotating component 5, the protrusions 7 abut against the elastic block 8 one by one. The rotating component 5 can drive the shell 1 to rotate around the pivot 2. During the rotation, the protrusions 7 on the outer edge of the rotating component 5 abut against the elastic block 8 one by one. The elastic deformation of the elastic block 8 generates a damping force to achieve folding and storage of the fitness device. The damping structure also avoids collisions or operational risks caused by the rapid rotation of the shell 1 due to inertia during the folding process.
[0026] Furthermore, in order to limit the rotation angle of the outer shell 1, an arc-shaped limiting hole 9 is provided on the rotating component 5, and a limiting slider 10 is provided in the rotating shaft component 2. The limiting slider 10 is slidably engaged with the arc-shaped limiting hole 9. The rotation angle of the rotating component 5 is limited by the movement range of the limiting slider 10 within the arc-shaped limiting hole 9, thereby preventing the outer shell 1 from rotating excessively, avoiding interference or damage between components due to excessive rotation, and improving the stability and service life of the folding structure.
[0027] Preferably, the two ends of the pivot 2 are provided with arc-shaped clearance holes 11 corresponding to the connection of the outer shell 1. The arc-shaped clearance holes are used to provide the rotating part 5 with a movable position to drive the outer shell 1 to rotate, so as to avoid interference between the rotating part 5 and the pivot 2 body when rotating, and ensure that the outer shell 1 can rotate smoothly during folding, thereby improving the smoothness of folding operation.
[0028] Preferably, the outer edge of the protrusion 7 and the outer edge of the elastic block 8 are both rounded, which can reduce the frictional resistance and stress concentration when they come into contact, reduce wear between the components, and extend the service life of the components.
[0029] In addition, the top of the rotating shaft 2 is provided with an installation port, and an elastic sheet 12 is provided in the installation port. An elastic block 8 is provided at the bottom of the elastic sheet 12 and located inside the rotating shaft 2. The installation port is used to install the elastic sheet 12, and the elastic block 8 is fixed to the bottom of the elastic sheet 12. When the elastic block 8 abuts against the protrusion 7, the elasticity of the elastic sheet 12 can provide continuous elastic support for the elastic block 8, so that the elastic sheet 12 can drive the elastic block 8 to perform secondary elastic adjustment, ensuring the stability of the damping effect.
[0030] It should be noted that both the elastic block 8 and the elastic sheet 12 can be made of materials such as plastic and rubber, which have good elastic deformation ability and are wear-resistant and durable, in order to adapt to long-term repeated stress conditions. No restrictions are imposed here.
[0031] In this embodiment, the rotating shaft 2 includes a first mounting base 21 and a second mounting base 22. The first mounting base 21 is provided with a first mounting sleeve 13 and a first insertion shaft 14. The second mounting base 22 is provided with a second mounting sleeve 15 and a second insertion shaft 16. The first mounting sleeve 13 and the second insertion shaft 16 are inserted and engaged to form a first rotating shaft 3. The second mounting sleeve 15 and the first insertion shaft 14 are inserted and engaged to form a second rotating shaft 4, thereby realizing the detachable assembly of the rotating shaft 2.
[0032] Furthermore, there are four elastic blocks 8, two of which are located inside the first mounting base 21 and the other two are located inside the second mounting base 22. Each outer shell 1 is provided with two rotating parts 5. The protrusions 7 of the two rotating parts 5 of each outer shell 1 correspond to the two elastic blocks 8 of the first mounting base 21 and the second mounting base 22, thereby forming a symmetrically distributed set of damping structures. This makes the damping force received by the outer shell 1 more balanced when it rotates, avoids the rotational deviation caused by uneven damping on one side, and improves the stability during folding and the user experience.
[0033] Furthermore, when the first mounting sleeve 13 and the second insertion shaft 16 are inserted and engaged, and when the second mounting sleeve 15 and the first insertion shaft 14 are inserted and engaged, the first mounting base 21 and the second mounting base 22 are connected by a male-female groove structure 17, thereby ensuring that the relative positions of the first mounting base 21 and the second mounting base 22 are accurately aligned, and improving the positioning accuracy of the rotating shaft assembly 2.
[0034] The implementation principle of a damped folding fitness device according to an embodiment of this application is as follows: Two symmetrically arranged outer shells 1 are rotatably connected to a rotating shaft 2 through their respective rotating parts 5. Specifically, the rotating parts 5 pass through a first rotating shaft 3 and a second rotating shaft 4 inside the rotating shaft 2 via rotating holes 6, allowing the outer shells 1 to rotate relative to each other around the shafts, thereby realizing the folding and unfolding action of the fitness device. During the rotation, the protrusions 7 on the outer edge of the rotating parts 5 rotate synchronously with the rotating parts 5 and abut against the elastic blocks 8 inside the rotating shaft 2 one by one. The elastic blocks 8 are elastically deformed by the compression of the protrusions 7. The damping force that resists rotation can buffer inertia, making the rotation of the outer shell 1 smooth and controllable, avoiding collisions of parts caused by rapid rotation. The corresponding arrangement of multiple sets of elastic blocks 8 and rotating parts 5 makes the damping effect more uniform, thereby improving the user experience. At the same time, the maximum rotation angle of the rotating part 5 is limited by the movement stroke of the limiting slider 10 in the arc-shaped limiting hole 9, preventing the outer shell 1 from rotating excessively. And the arc-shaped clearance openings 11 at both ends of the rotating shaft 2 provide sufficient space for the rotating part 5 to drive the outer shell 1 to rotate.
[0035] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
