DETAILED DESCRIPTION

[0033] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The following combination Figure 1-Figure 4 The present invention describes a rhythmic frame and rhythmic furniture that moves up and down. The rhythmic furniture includes the above-mentioned rhythmic frame and a supporting body mounted on the rhythmic frame. It is understood that in the embodiment of the present invention, the above-mentioned rhythmic furniture can be a rhythmic chair, a rhythmic bed, etc.

[0035] Reference Figures 1 to 4 The utility model provides a rhythmic frame that moves up and down, including a fixed base frame 100, a rhythmic support 200, a driving mechanism 300 and a supporting and guiding mechanism 400. The rhythmic support 200 is arranged above the fixed base frame 100, and the rhythmic support 200 is configured to move up and down relative to the fixed base frame 100. The driving mechanism 300 is arranged on the fixed base frame 100, and the output end of the driving mechanism 300 is transmission-connected with the rhythmic support 200. One end of the supporting and guiding mechanism 400 is installed on the fixed base frame 100, and the other end of the supporting and guiding mechanism 400 is installed on the rhythmic support 200. The height of the supporting and guiding mechanism 400 is configured to be automatically adjusted following the up and down movement of the rhythmic support 200 relative to the fixed base frame 100.

[0036] The present invention provides a rhythmic frame that moves up and down. The rhythmic frame 200 is located above the fixed base frame 100, and the driving mechanism 300 drives the rhythmic frame 200 to move up and down relative to the fixed base frame 100 to achieve rhythmic movement. The support guide mechanism 400 is provided, and the height of the support guide mechanism 400 is configured to be adjustable to accommodate the rhythmic movement. This not only improves the movement stability of the rhythmic frame 200, but also better adapts to the up and down movement frequency of the rhythmic frame 200, achieving flexible height adjustment, helping to prevent movement stagnation, and providing support for the rhythmic frame 200 to a certain extent.

[0037] It is understandable that, referring to Figures 1 to 4 In an embodiment of the utility model, the supporting guide mechanism 400 includes a first mounting structure 410, a second mounting structure 420 and a guide column 430. The first mounting structure 410 is mounted on the fixed base frame 100, and the second mounting structure 420 is mounted on the rhythmic bracket 200. One end of the guide column 430 is fixedly connected to the first mounting structure 410, and the other end of the guide column 430 is movably connected to the second mounting structure 420.

[0038] Of course, in some embodiments, the first mounting structure 410 can also be installed and connected to the rhythmic bracket 200, and the second mounting structure 420 is installed on the fixed base frame 100, which is not limited here.

[0039] With the above structure, one end of the guide column 430 is fixed to the first mounting structure 410, and the other end is movably connected to the second mounting structure 420, so that the height of the supporting guide mechanism 400 can be adjusted according to the up and down movement of the rhythm bracket 200; the design of the guide column 430 is conducive to ensuring that the rhythm bracket 200 can only move along a specific direction, which not only improves the accuracy and stability of the movement of the rhythm bracket 200, but also reduces the direct contact between the rhythm bracket 200 and the fixed base frame 100, reduces friction and wear, and extends the service life of the rhythm furniture; through the arrangement of the first mounting structure 410 and the second mounting structure 420, a stable support is provided for the entire rhythm bracket 200.

[0040] Specifically, refer to Figures 1 to 4 In the embodiment of the present utility model, the first mounting structure 410 is provided with a mounting channel 4111 , the end of the guide column 430 is inserted into the mounting channel 4111 , and the end of the guide column 430 is relatively fixed to the mounting channel 4111 .

[0041] With the above structure, the end of the guide column 430 is relatively fixed to the installation channel 4111, ensuring that the position of the guide column 430 in the first installation structure 410 is fixed, thereby providing a stable reference point for the entire supporting guide mechanism 400 and improving reliability.

[0042] Specifically, refer to Figures 1 to 4 In this embodiment of the utility model, the first mounting structure 410 is detachably connected to the guide post 430. With this arrangement, if the guide post 430 or the first mounting structure 410 needs to be replaced, the guide post 430 can be quickly removed from the mounting channel 4111, separating the guide post 430 and the first mounting structure 410 for easy maintenance and replacement.

[0043] Specifically, refer to Figures 1 to 4 In this embodiment of the present invention, the first mounting structure 410 includes a first mounting base 411 and a fixing bolt 412. The first mounting base 411 is mounted on the fixed base 100, and the fixing bolt 412 is mounted on the first mounting base 411. The fixing bolt 412 is threadedly connected to the guide column 430. With this structure, the threaded connection simplifies the connection process between the guide column 430 and the first mounting base 411, making installation and removal faster and more convenient, and reducing manufacturing costs.

[0044] It is understandable that, referring to Figures 1 to 4In the embodiment of the present utility model, an internal thread groove is provided at the bottom of the guide column 430, and the above-mentioned mounting channel 4111 is provided on the first mounting seat 411, and a connecting through-hole 4112 and a fixing groove 4113 are also provided on the first mounting seat 411, and the fixing groove 4113 is connected to the mounting channel 4111 through the connecting through-hole 4112, and the fixing bolt 412 is installed in the fixing channel, and the threaded rod of the fixing bolt 412 is inserted into the mounting channel 4111 through the connecting through-hole 4112 and is threadedly connected to the internal thread groove at the bottom of the guide column 430, wherein the cross-sectional area of ​​the connecting through-hole 4112 is smaller than the head of the fixing bolt 412, which limits the installation position of the fixing bolt 412, prevents the fixing bolt 412 from moving up and down, and improves the assembly stability between the first mounting seat 411 and the fixing bolt 412.

[0045] It should be noted that, in this embodiment, a connecting plate is fixed to the upper surface of the fixed base 100 corresponding to the first mounting seat 411 by welding or installing bolts, and the connecting plate and the first mounting seat 411 are fixedly connected by a first connecting bolt to facilitate disassembly and maintenance. Of course, in some embodiments, the above-mentioned connecting plate and the first mounting seat 411 can also be fixedly connected by means of a snap fastener, etc. Of course, welding, etc. can also be selected to fix the connecting plate and the first mounting seat 411, which is not limited here.

[0046] Of course, in some embodiments, the guide column 430 may also be fixedly connected to the fixed base frame 100 by means of a pin, a buckle, etc., which is not limited here.

[0047] Specifically, refer to Figures 1 to 4 In the embodiment of the present invention, a movable channel 421 is provided on the second mounting structure 420 , and the end of the guide column 430 is inserted into the movable channel 421 , and the end of the guide column 430 can move up and down relative to the movable channel 421 .

[0048] With the above structure, the end of the guide column 430 moves up and down in the moving channel 421, which not only allows the rhythmic bracket 200 to be positionally adjusted in the up and down directions, but also increases the flexibility of use of the supporting guide mechanism 400; the moving channel 421 limits the lateral movement of the guide column 430, thereby reducing the impact of lateral force on the supporting guide mechanism 400 and improving the smoothness of movement.

[0049] Of course, in some embodiments, the second mounting structure 420 and the guide column 430 may also be matched in the form of a linear slide rail, which is not limited here.

[0050] Specifically, in an embodiment of the present invention, the second mounting structure 420 is a second mounting seat, and the movable channel 421 passes through the second mounting seat in the up and down directions. The through movable channel 421 is provided on the second mounting seat, which can simplify the overall structure of the supporting guide mechanism 400 and reduce the number and complexity of parts.

[0051] It should be noted that, referring to Figures 1 to 4 In the embodiment of the present utility model, a mounting base column 210 is provided at the bottom of the rhythmic bracket 200, and the mounting base column 210 is provided with a accommodating cavity 211. The accommodating cavity and the movable channel 421 correspond to and are connected. The accommodating cavity 211 is adapted to the guide column 430, so that the end portion of the guide column 430 facing the rhythmic bracket 200 can extend into the accommodating cavity 211 and be covered and positioned by the accommodating cavity 211. When the guide column 430 can move up and down relative to the movable channel 421, it will also move up and down relative to the accommodating cavity 211, further improving the movement stability and assembly stability of the guide column 430.

[0052] In an embodiment of the present invention, the above-mentioned mounting base column 210 and the second mounting seat are fixedly connected by multiple second connecting bolts to facilitate disassembly and maintenance. Of course, in some embodiments, the above-mentioned mounting base column 210 and the second mounting seat can also be fixedly connected by means of snap fasteners, etc. Of course, welding, etc. can also be selected to fix the mounting base column 210 and the second mounting seat, which is not limited here.

[0053] It should also be noted that, in this embodiment, the guide column 430 can be either a non-elastic column or a column with a certain degree of elasticity to adapt to different application requirements and working conditions. For example, the guide column 430 with a certain degree of elasticity can adapt to the slight left and right deviation of the rhythmic bracket 200 relative to the fixed base frame 100.

[0054] It is understandable that, referring to Figure 1 In the embodiment of the present utility model, there are four groups of supporting and guiding mechanisms 400, and the four groups of supporting and guiding mechanisms 400 are arranged at circumferential intervals between the fixed base frame 100 and the rhythmic support 200.

[0055] Using the above structure, it can be understood that, in this embodiment, the fixed base frame 100 and the rhythmic support 200 are both rectangular structures, and the four groups of supporting and guiding mechanisms 400 are circumferentially spaced at the four corners of the fixed base frame 100, which helps to evenly distribute the load from the rhythmic support 200 to the fixed base frame 100, reduce local stress concentration, and improve the stability of the overall structure.

[0056] Of course, in some embodiments, the supporting and guiding mechanism 400 can also be one group, two groups, etc., and can be adaptively set according to needs and the shape of the rhythm frame.

[0057] It is understandable that, referring to Figure 1 In an embodiment of the present utility model, the driving mechanism 300 includes a driving motor 310, an eccentric shaft 320, a transmission member 330 and a transmission shaft 340. The driving motor 310 is arranged on the fixed base frame 100, and the eccentric shaft 320 is rotatably arranged on the fixed base frame 100. The eccentric shaft 320 is provided with an output end of a first driving motor 310 and is transmission-connected to the eccentric shaft 320. One end of the transmission member 330 is transmission-connected to the eccentric shaft 320. The transmission shaft 340 is connected to the rhythmic bracket 200, and the other end of the transmission member 330 is connected to the transmission shaft 340. Among them, the rotation center line of the partial structure at the matching location of the transmission member 330 and the eccentric shaft 320 does not coincide with the rotation center line of the partial structure at the matching location of the output end of the driving motor 310 and the eccentric shaft 320.

[0058] With the above structure, due to the design of the eccentric shaft 320, the rotational motion generated by the drive motor 310 is converted into eccentric motion, thereby generating a periodic torque on the transmission shaft 340, so that the rhythmic bracket 200 reciprocates up and down relative to the fixed base frame 100. The structure is compact and provides flexible, efficient and precise motion control.

[0059] Specifically, refer to Figure 1 In this embodiment of the present invention, the transmission member 330 is vertically positioned between the upper portion of the fixed base frame 100 and the lower portion of the rhythm frame 200. This arrangement helps optimize the spatial layout within the rhythm frame, making the overall structure more compact. Furthermore, the transmission member 330 not only enables transmission but also provides support and stability for the rhythm frame 200 to a certain extent, better transmitting power and supporting vertical forces. This improves the movement stability of the rhythm frame 200, thereby enhancing the stability of the entire rhythm frame.

[0060] It should be noted that in the embodiment of the present invention, the output end of the drive motor 310, that is, the rotating shaft of the drive motor 310, is connected to the eccentric shaft 320 through a coupling; of course, in some embodiments, the rotating shaft of the drive motor 310 can also be connected to the eccentric shaft 320 through a pulley transmission structure or a gear transmission structure, which is not limited here.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
