Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular discloses a vibration fitness structure that is easy to fold and store. Background Technology

[0002] With increasing emphasis on health and fitness, vibration fitness equipment, as an effective exercise tool, is gaining popularity due to its effects on muscle stimulation, improved blood circulation, increased muscle strength, and fat reduction. However, existing vibration fitness equipment is typically bulky, making it inconvenient to store in a home environment, especially in limited spaces, where it often occupies a significant amount of space. Furthermore, because vibration fitness equipment needs to support a substantial body weight and withstand continuous vibration, its structure must be sufficiently robust and stable. This often results in a cumbersome design, further increasing the difficulty of moving and storing the equipment.

[0003] Existing vibration fitness equipment typically cannot be easily folded and stored without affecting its normal function. Even if some equipment has partial folding capabilities, it is relatively complicated to operate, requiring users to exert considerable physical effort during folding and unfolding. Furthermore, the structural stability after folding is often insufficient, posing certain safety hazards. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a vibration fitness device that is foldable, structurally stable, and easy to operate.

[0005] To achieve the above objectives, this utility model provides a foldable and easily stored vibration fitness structure, including a base frame, a drive mechanism mounted on the base frame, and a bracket connected to the drive mechanism. The drive mechanism drives the bracket to move relative to the base frame. It also includes a lifting frame with a lifting component. One end of the lifting frame is rotatably connected to the base frame, one end of the lifting component is connected to the lifting frame, and the other end of the lifting component is connected to the base frame. In a first state, the base frame abuts against the lifting frame, and the lifting frame and base frame cooperate to rest on an external bearing surface. In a second state, the lifting component drives the base frame to rotate relative to the lifting frame, causing the base frame to detach from the external bearing surface. This utility model, through the foldable design of the lifting frame and base frame, allows the device to be easily folded and unfolded, saving space, facilitating storage, and improving ease of use.

[0006] Furthermore, the base frame is equipped with a transmission assembly, which includes a connecting rod component. The lifting frame is rotatably connected to the base frame via the transmission assembly. The design of the transmission assembly makes the movement of the lifting frame and the base frame smoother and more precise, helping to reduce swaying or instability during folding.

[0007] Furthermore, the lifting assembly is an electric push rod, with one end rotatably connected to the end of the lifting frame away from the base frame, and the other end rotatably connected to the base frame. The electric push rod provides automated folding and unfolding functions, improving the ease of use of the equipment and reducing labor.

[0008] Furthermore, the connecting rod components are provided in multiple sets, with these sets of connecting rod components evenly spaced along the length of the lifting frame. This even distribution of multiple sets of connecting rod components along the length ensures uniform force distribution on the lifting frame during movement, and the multi-point connection significantly improves the stability of the entire structure during movement, extending the service life of the equipment.

[0009] Furthermore, a support block is provided at the end of the lifting frame away from the base frame. In the first state, the support block abuts against the base frame. The support block can stably support the base frame during equipment use, preventing the equipment from shaking or tilting, thus improving the stability and safety of the equipment during use, especially preventing accidental displacement of the equipment during movement.

[0010] Furthermore, a sliding assembly is provided on the base frame, which is connected to the bracket via the sliding assembly. The sliding assembly includes a fixed seat, a movable seat movably disposed relative to the fixed seat, and a roller component rolling between the fixed seat and the movable seat. The fixed seat is disposed on the base frame, and the movable seat is disposed on the bracket. The fixed seat has a first groove, and the movable seat has a second groove for engaging with the first groove. The roller component is accommodated in the groove, with its two ends respectively accommodated in the first groove and the second groove. The design of the sliding assembly allows the bracket to slide smoothly, improving the flexibility of the equipment, delaying wear between the two components, reducing vibration friction of the vibrating structure, extending service life, and improving the stability of the vibrating structure's operation.

[0011] Furthermore, the sliding assembly is equipped with a limiting component, which limits the reciprocating travel distance of the bracket along the slide rail. The limiting component restricts the bracket's movement range, preventing it from exceeding its safe travel distance, thus allowing precise control of the bracket's movement distance and avoiding equipment damage or misoperation.

[0012] Furthermore, the drive device includes a support platform mounted on a base frame, a drive motor mounted on the support platform, and an eccentric mechanism connected to the output shaft of the drive motor. The eccentric mechanism includes an eccentric shaft rotatably mounted on the support platform and a transmission link connected to the eccentric shaft. One end of the transmission link is provided with a transmission sleeve, which is rotatably fitted onto the outside of the eccentric shaft. The other end of the transmission link is connected to a transmission bracket. The eccentric shaft is connected to the output shaft of the drive motor. The eccentric mechanism efficiently converts the rotational motion of the motor into reciprocating motion, ensuring a vibration effect and suitable for various fitness needs.

[0013] Furthermore, the drive device also includes a reduction mechanism connected between the eccentric shaft and the drive motor. The reduction mechanism includes a first pulley, a second pulley, a third pulley, a fourth pulley, and two belts. The first pulley is connected to the output shaft of the drive motor. The second pulley is connected to the first pulley via a belt drive. The second and third pulleys are coaxially rotatably connected. The third and fourth pulleys are connected via another belt drive. The fourth pulley is connected to the eccentric shaft. The outer diameters of the first and third pulleys are equal, as are the outer diameters of the second and fourth pulleys. The outer diameter of the first pulley is smaller than that of the second pulley. This reduction mechanism makes the motor output smoother and the vibration effect more suitable, avoiding unnecessary vibration caused by high speeds and increasing the applicability of the equipment.

[0014] Furthermore, the eccentric mechanism also includes a buffer arm. The end of the transmission link away from the transmission sleeve is rotatably connected to one end of the buffer arm, and the end of the buffer arm away from the transmission link is used to connect to the bracket. A soft rubber pad is provided at the rotatable engagement point between the buffer arm and the transmission link. The design of the soft rubber pad and the buffer arm effectively absorbs vibrations and reduces their impact on the user. The vibration buffering design improves the user's comfort during use.

[0015] The beneficial effects of this utility model are as follows: By setting up a folding design for the lifting frame and the base frame, the equipment can be easily folded and unfolded, saving space, facilitating storage, and improving ease of use; the design of the transmission components makes the movement of the lifting frame and the base frame more stable and precise, which helps to reduce shaking or instability during folding; the electric push rod can provide automated folding and unfolding functions, improving the ease of use of the equipment and saving more effort.

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Please see Figures 1 to 5 As shown, this utility model discloses a vibrating fitness structure that is easy to fold and store. It includes a base frame 1, a drive mechanism 2 mounted on the base frame 1, and a bracket 3 connected to the drive mechanism 2. The drive mechanism 2 drives the bracket 3 to move relative to the base frame 1. It also includes a lifting frame 4, on which a lifting component 5 is mounted. One end of the lifting frame 4 is rotatably connected to the base frame 1, one end of the lifting component 5 is connected to the lifting frame 4, and the other end of the lifting component 5 is connected to the base frame 1. In a first state, the base frame 1 abuts against the lifting frame 4, and the lifting frame 4 and base frame 1 cooperate to rest on an external bearing surface. In a second state, the lifting component 5 drives the base frame 1 to rotate relative to the lifting frame 4, causing the base frame 1 to detach from the external bearing surface. This utility model, through the folding design of the lifting frame 4 and the base frame 1, allows the device to be easily folded and unfolded, saving space, facilitating storage, and improving ease of use.

[0025] The base frame 1 is equipped with a transmission assembly, which includes a connecting rod member 6. The lifting frame 4 is rotatably connected to the base frame 1 via the transmission assembly. The design of the transmission assembly makes the movement of the lifting frame 4 and the base frame 1 more stable and precise, which helps to reduce swaying or instability during folding.

[0026] The lifting assembly 5 is an electric push rod. One end of the electric push rod is rotatably connected to the end of the lifting frame 4 away from the base frame 1, and the other end of the electric push rod is rotatably connected to the base frame 1. The electric push rod can provide automated folding and unfolding functions, improving the ease of use of the equipment and reducing labor.

[0027] Multiple sets of connecting rod components 6 are provided, and these sets of connecting rod components 6 are evenly spaced along the length of the lifting frame 4. The even distribution of multiple sets of connecting rod components 6 along the length ensures that the lifting frame 4 is subjected to uniform force during movement. The multi-point connection greatly improves the stability of the entire structure during movement and extends the service life of the equipment.

[0028] A support block 7 is provided on the end of the lifting frame 4 away from the base frame 1. In the first state, the support block 7 abuts against the base frame 1. The support block 7 can stably support the base frame 1 during equipment use, preventing the equipment from shaking or tilting, thus improving the stability and safety of the equipment during use, especially preventing accidental displacement of the equipment during movement.

[0029] A sliding assembly 8 is provided on the base frame 1, which is connected to the bracket 3 via the sliding assembly 8. The sliding assembly 8 includes a fixed seat 9, a movable seat 10 movably disposed relative to the fixed seat 9, and a roller component rolling between the fixed seat 9 and the movable seat 10. The fixed seat 9 is disposed on the base frame 1, and the movable seat 10 is disposed on the bracket 3. The fixed seat 9 has a first groove, and the movable seat 10 has a second groove for engaging with the first groove. The roller component is accommodated in the groove, with its two ends respectively accommodated in the first groove and the second groove. The design of the sliding assembly 8 allows the bracket 3 to slide smoothly, improving the flexibility of the equipment, delaying wear between the two components, reducing vibration friction of the vibrating structure, extending service life, and improving the stability of the vibrating structure's operation.

[0030] A limiting element 11 is provided on the sliding assembly 8. The limiting element 11 is used to limit the reciprocating travel distance of the bracket 3 along the slide rail. The limiting element 11 restricts the movement range of the bracket 3, prevents the bracket 3 from exceeding the safe travel distance, and can accurately control the movement distance of the bracket 3 to avoid equipment damage or misoperation.

[0031] The drive unit includes a support platform 12 mounted on a base frame 1, a drive motor 13 mounted on the support platform 12, and an eccentric mechanism connected to the output shaft of the drive motor 13. The eccentric mechanism includes an eccentric shaft 14 rotatably mounted on the support platform 12 and a transmission link 15 drively connected to the eccentric shaft 14. One end of the transmission link 15 is provided with a transmission sleeve 16, which rotatably fits around the outside of the eccentric shaft 14. The other end of the transmission link 15 is connected to a transmission bracket 3. The eccentric shaft 14 is connected to the output shaft of the drive motor 13. The eccentric mechanism efficiently converts the rotational motion of the motor into reciprocating motion, ensuring vibration effect and suitable for various fitness needs.

[0032] The drive unit also includes a reduction mechanism 17 connected between the eccentric shaft 14 and the drive motor 13. The reduction mechanism 17 includes a first pulley 18, a second pulley 19, a third pulley 20, a fourth pulley 21, and two belts. The first pulley 18 is connected to the output shaft of the drive motor 13. The second pulley 19 is connected to the first pulley 18 via a belt drive. The second pulley 19 and the third pulley 20 are coaxially rotatably connected. The third pulley 20 and the fourth pulley 21 are connected via another belt drive. The fourth pulley 21 is connected to the eccentric shaft 14. The outer diameters of the first pulley 18 and the third pulley 20 are equal, and the outer diameters of the second pulley 19 and the fourth pulley 21 are equal. The outer diameter of the first pulley 18 is smaller than that of the second pulley 19. The reduction mechanism 17 makes the motor output smoother and the vibration effect more suitable, avoiding unnecessary vibration caused by high speed and increasing the applicability of the equipment.

[0033] The eccentric mechanism also includes a buffer arm 22. The end of the transmission link 15 away from the transmission sleeve 16 is rotatably connected to one end of the buffer arm 22. The end of the buffer arm 22 away from the transmission link 15 is used to connect to the bracket 3. A soft rubber pad is provided at the rotatable engagement point between the buffer arm 22 and the transmission link 15. The design of the soft rubber pad and the buffer arm 22 effectively absorbs vibration and reduces the impact of vibration on the user. The vibration buffering design improves the user's comfort during use.

[0034] Specifically, the bracket 3 is equipped with a soft pad, which allows users to perform various fitness exercises, thereby improving user comfort.

[0035] In this embodiment, when the power is turned on, the drive motor 13 is started, and the drive motor 13 drives the first pulley 18 to rotate. Since the first pulley 18 and the second pulley 19 are connected by belt drive, and the outer diameter of the first pulley 18 is smaller than the outer diameter of the second pulley 19, according to the characteristics of belt drive, the speed of the second pulley 19 will be lower than the speed of the first pulley 18, thus achieving the first deceleration.

[0036] Next, since the second pulley 19 and the third pulley 20 are coaxially connected, their rotational speeds are the same. However, the third pulley 20 and the fourth pulley 21 are connected by another belt drive, and the outer diameters of the third pulley 20 and the first pulley 18 are equal, as are the outer diameters of the fourth pulley 21 and the second pulley 19. This means that the transmission ratio from the third pulley 20 to the fourth pulley 21 is the same as the transmission ratio from the first pulley 18 to the second pulley 19. Therefore, the rotational speed of the fourth pulley 21 will be further reduced, that is, the rotational speed of the eccentric shaft 14 is reduced twice. Finally, the reduced-speed eccentric shaft 14 drives the transmission link 15 and the bracket 3 to move, realizing power transmission and mechanical motion. Users can perform various fitness exercises on the bracket 3, using vibration to stimulate muscles and improve fitness effects.

[0037] After use, first stop the drive motor 13 to ensure that the equipment no longer vibrates. The lifting frame 4 and the base frame 1 are placed on the external bearing surface. The lifting component 5 drives the base frame 1 to rotate relative to the lifting frame 4 through the transmission component, so that the base frame 1 is separated from the external bearing surface, and the base frame 1 and the bracket 3 are erected to save storage space.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
