Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fitness equipment, in particular to the technical field of a dynamic device. BACKGROUND

[0002] In the design of a dynamic mechanism, the layout of the guide mechanism and the friction mechanism has a crucial influence on the overall performance, reliability and user experience of the equipment.

[0003] Most guide mechanisms and friction mechanisms are integrated into one design, such as the guide, friction and damping of the horizontal dynamic machine of the chassis assembly and dynamic furniture of Chinese patent CN221450255U. However, integration generally has the problem of difficult leveling adjustment, and increases the difficulty of maintenance, because repairing or replacing faulty parts often requires disassembling the entire device.

[0004] Some products also use a split design, where the guide and friction mechanisms are separated, and the friction usually occurs on the ground. The most significant problem is that the ground is damaged by friction during movement on the ground. At the same time, the problem of ground flatness further aggravates the friction damage. SUMMARY

[0005] To solve the above problems, the present application proposes a dynamic device, which adopts a split design of the guide mechanism and the friction mechanism, and avoids the friction of the friction mechanism on the ground, at least improving the friction and leveling stability problems existing in the prior art.

[0006] To achieve the above purpose, the following technical solutions are adopted in the present application:

[0007] A dynamic device, comprising a bed frame and a dynamic frame reciprocating along the horizontal direction relative to the bed frame;

[0008] The bed frame is provided with an adjustment foot in contact with the ground and capable of adjusting the levelness of the bed frame;

[0009] The dynamic frame is provided with a roller in contact with the upper end of the bed frame and reciprocating on the bed frame;

[0010] Further comprising a dynamic mechanism arranged horizontally along the dynamic direction, and the two ends of the dynamic direction are respectively fixed with the bed frame and the dynamic frame.

[0011] In this way, the dynamic mechanism for transmission and the roller for friction are split and arranged, and the roller is arranged to move on the bed frame. The friction in the vertical direction occurs on the bed frame rather than on the ground, providing more stable and consistent friction, thereby ensuring the accuracy and reliability of the dynamic process.

[0012] The motion mechanism is integrated in the bed body, which eliminates the influence of external environment on the motion, improves the overall stability of the system, and reduces the requirements for external installation conditions, so that the motion device can be used in more diversified environments.

[0013] In some possible embodiments, the rollers are arranged on the motion frame through a fixing frame provided with shaft holes, and an embedded anti-rotation block for adjusting the height of the rollers is arranged at least at one of the shaft holes. The height of the rollers can be adjusted through the embedded anti-rotation block, and thus the flatness of the motion frame can be adjusted.

[0014] In a preferred embodiment, the embedded anti-rotation blocks are two and are arranged at the fixed end of the motion mechanism and the motion frame.

[0015] In a preferred embodiment, the shaft hole at the installation position of the embedded anti-rotation block is a square slot inclined downward toward the motion mechanism, so that the embedded anti-rotation block is locked in the direction of the driving force during work, improving the stability.

[0016] In some possible embodiments, the fixing frame is provided with an extension portion toward the bottom of the bed frame, and the extension portion is provided with a position limiter for preventing the motion frame from being separated. The position limiter is arranged on the fixing frame where the rollers are arranged, so as to ensure that the motion is always within the designed range.

[0017] In some possible embodiments, a wear-resistant gasket arranged on the upper end of the bed frame to cover the travel of the rollers is further included.

[0018] In some possible embodiments, the bed frame is provided with a first transverse support, and the first transverse support is connected to the motion mechanism through a support rib.

[0019] In a preferred embodiment, the support rib includes a rib portion and a clamping portion clamping the first transverse support at the bottom of the rib portion. The combination of the rib portion and the clamping portion significantly enhances the connection rigidity between the bed frame and the motion mechanism, and improves the stability and carrying capacity of the overall structure.

[0020] In some possible embodiments, a control device arranged in the bed frame is further included. BRIEF DESCRIPTION OF DRAWINGS

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0031] First, as a prior art of horizontal motion device, a horizontal motion bed of Chinese patent CN221265684U discloses a bed frame and a motion device detachably connected with the bed frame, and a roller assembly provided on the bed frame enclosure. At this time, the roller assembly and the motion device are designed in a split body, and the foot pad of the motion device and the roller assembly are respectively in contact with the ground, that is, the work is also split work. Two kinds of separate contact and separate work will cause friction and leveling stability problems.

[0032] It needs to be further explained that the pulsation mechanism of the horizontal pulsation bed in Chinese Patent CN221265684U is a component mainly serving as a pulsation power component, which includes a vibration assembly, a guide assembly, and a buffer assembly. In the application file of the present application, the description of the vibration assembly, the guide assembly, and the buffer assembly will also be used, and their working principles and functions are the same as those of the same components in the horizontal pulsation bed in Chinese Patent CN221265684U, which will not be described in detail in the present patent.

[0033] Please refer to Figure 1 and Figure 2 The pulsation device of the present application includes a bed frame 1 and a pulsation frame 2 reciprocating in a horizontal direction relative to the bed frame 1.

[0034] Specifically, the bed frame 1 is provided with a first frame 11, and an adjusting foot 12 is arranged at the bottom of the first frame 11 and in contact with the ground, which provides support and also serves to adjust the levelness of the bed frame 1. The specific form of the adjusting foot 12 is a common technical means in the furniture or sports equipment industry, which will not be described in detail. A first transverse support 13 is arranged between the first frames 11.

[0035] The pulsation frame 2 is provided with a second frame 21, and a second transverse support 22 is arranged between the second frames 21. A roller 23 is arranged at the bottom of the second frame 2 and in contact with the upper end of the bed frame 1 and reciprocating on the bed frame 1, and the number of rollers 23 is preferably four.

[0036] The roller 23 is detachably connected, and Figure 1 is the installation state, Figure 2 is a disassembly state diagram. In implementation, the roller 23 is arranged on the pulsation frame 2 through a fixing frame 24, an axle hole is arranged on the fixing frame 24, and the roller 23 is connected through the axle hole to make the roller 23 rotate.

[0037] The pulsation mechanism 3 as a power mechanism is arranged horizontally along the pulsation direction, and the two ends of the pulsation direction are fixed to the bed frame 1 and the pulsation frame 2, respectively. The pulsation mechanism 3 includes a first pulsation mounting plate 31 and a second pulsation mounting plate 32, and further includes a vibration assembly 33, a guide assembly 34, and a buffer assembly 35 arranged between the mounting plates. In this way, the power device for pulsation is formed, and will not be described in detail.

[0038] And the design of the first pulsation mounting plate 31 and the second pulsation mounting plate 32 is more convenient for the installation of the vibration assembly 33, the guide assembly 34, and the buffer assembly 35, which can be completed directly on the outside of the mounting plate.

[0039] Please continue to refer to Figure 1 and Figure 2Specifically, the first rhythm installation plate 31 of the rhythm mechanism 3 is connected with the first lateral support 13 through the support rib 4. The second rhythm installation plate 32 of the rhythm mechanism 3 is fixedly connected with the second lateral support 22. Meanwhile, the control device 5 can be arranged in the bed frame 1.

[0040] In this way, the rhythm mechanism 3 which plays a transmission role and the roller 23 which plays a friction role are arranged separately, and the roller 23 is arranged to move on the bed frame 1. The friction in the vertical direction occurs on the bed frame 1 rather than the ground, which provides more stable and consistent friction, thereby ensuring the accuracy and reliability of the rhythm process.

[0041] The rhythm mechanism 3 arranged laterally between the bed frame 1 and the rhythm frame 2 integrates the movement mechanism in the bed body 1, eliminates the influence of the external environment on the movement, improves the overall stability of the system, and reduces the requirement for external installation conditions, so that the rhythm device can be used in more diversified environments.

[0042] Preferably, the support rib 4 comprises a rib portion 41 and a clamping portion 42 clamping the first lateral support 13 at the bottom of the rib portion 41. The combination of the rib portion 41 and the clamping portion 42 significantly enhances the connection rigidity between the bed frame 1 and the rhythm mechanism 3, and improves the stability and carrying capacity of the overall structure.

[0043] In actual application, the adjusting feet 12 are in contact with the ground, and the flatness of the bed frame 1 is ensured through the adjusting feet 12. As described above, the bed frame 1 and the rhythm frame 2 are connected through the rhythm mechanism 3 as the medium, and therefore when the adjusting feet 12 are adjusted, the flatness of the rhythm frame 2 will also be affected. Therefore, the height of the roller 23 also needs to be adjusted, and the roller 23 is different from the adjusting feet 12 in that the roller 23 is a moving part. Therefore, the present application also improves the design.

[0044] Please refer to Figures 3 to 5 At least one adjustable height embedded anti-rotation block 25 is arranged at the shaft hole, which can adjust the height of the roller 23, and thereby adjust the flatness of the rhythm frame 2. Preferably, two embedded anti-rotation blocks 25 are arranged at the front direction side of the rhythm frame 2, that is, the fixed end of the rhythm frame 2 and the rhythm mechanism 3. The embedded anti-rotation block 25 is a square-shaped sliding block provided with a T-shaped head and can slide in the shaft hole, and is provided with a through hole through which a bolt can pass. In this way, the height of the roller 23 can be adjusted by adjusting the position of the embedded anti-rotation block 25 in the shaft hole.

[0045] Preferably, the shaft hole at the installation position of the embedded anti-rotation block 25 is a square-shaped groove 251 inclined downward toward the rhythm mechanism 3, so that the embedded anti-rotation block 25 is locked in the direction of the driving force during work, thereby improving the stability.

[0046] Please refer to Figure 6 The fixed frame 24 is provided with an extension 241 towards the bottom of the bed frame 1, and the extension 241 is provided with a position limiter 242 to prevent the rhythmic frame 2 from being detached. The position limiter 242 is arranged on the fixed frame 24 where the rolling wheel 23 is installed, so as to ensure that the movement is always within the designed range.

[0047] Please refer to Figure 4 In some preferred modes, considering that the moving distance of the rhythm is short and repeated, the rolling wheel 23 has the demand of wear resistance in addition to preventing the rhythmic frame 2 from being detached. For this purpose, a wear-resistant pad 6 is arranged on the upper end of the bed frame 1 to cover the travel of the rolling wheel 23. The optional material is metal with good wear resistance and small damping, such as steel sheet, aluminum alloy sheet, etc.

[0048] When applied, the rhythmic device of the present application can be applied to beds, sofas, chairs and other furniture.

[0049] As described above, the present case protects a rhythmic device, and all technical solutions identical or similar to the present case should be shown to fall within the protection scope of the present case.
