DETAILED DESCRIPTION

[0039] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the present application will be described below in connection with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the present application.

[0040] In related technologies, the patent with the publication number CN219896292U discloses an up-down vibration device, which is used as a rhythm machine core. The transmission structure of the device is relatively complex. The transmission structure has multiple hinge points with the matched frame body, and also has multiple hinge points with the driven power structure, which is relatively cumbersome to install. In addition, there is a gap between the transmission structure and the moving frame body, or there is a gap between the transmission structure and the driven power structure, which is prone to produce noise.

[0041] The rhythm machine core and the rhythm furniture of the present application will be described below in connection with Figures 1-4 The rhythm furniture includes a massage body for bearing a user and a rhythm machine core arranged at the bottom of the massage body. It should be noted that in some embodiments of the present application, the rhythm furniture is a rhythm chair, and the rhythm machine core is located at the bottom of the rhythm chair. Of course, in some embodiments, the rhythm machine core can be applied to furniture of types such as rhythm sofas and rhythm beds.

[0042] It can be understood that, with reference Figures 1 to 3 The present application provides a rhythm machine core for balanced elastic movement up and down, which includes a first frame body 100, a second frame body 200, a transmission structure, and a driving mechanism 400. The second frame body 200 and the first frame body 100 can move up and down relative to each other. The transmission structure includes at least one elastic transmission member 300. The elastic transmission member 300 is arranged between the first frame body 100 and the second frame body 200. One end of the elastic transmission member 300 is connected to the first frame body 100, and the other end is connected to the second frame body 200. The driving mechanism 400 is arranged at the first frame body 100. The power output end of the driving mechanism 400 is in transmission cooperation with the elastic transmission member 300.

[0043] The driving mechanism 400 can push the elastic transmission member 300 to swing up and down to drive the second frame body 200 to move up and down relative to the first frame body 100.

[0044] The beat movement mechanism provided by the utility model can be balanced in up-down elastic movement through the use of the elastic transmission member 300, which can be directly connected with the first frame body 100 and the second frame body 200, thereby reducing the number of hinged points and simplifying the structure.

[0045] The elastic transmission member 300 provides certain flexibility, allowing for a certain positional deviation during installation, without the need for precise alignment, thereby reducing the difficulty of installation; due to the simple transmission structure, the number of steps that need to be adjusted during installation is reduced, thereby saving installation time and labor; the elastic transmission member 300 can absorb and disperse vibrations during transmission, reducing hard impact and thereby reducing noise.

[0046] Therefore, through the above design improvement, the above structure not only simplifies the transmission structure of the beat movement mechanism, but also improves the convenience, reliability and comfort during use, while reducing maintenance costs and operating noise.

[0047] Due to the horizontal arrangement of the elastic transmission member 300, which has elasticity in the up-down direction, the second frame body 200 is limited in up-down movement and cannot deviate left or right, thereby providing a beat movement that is balanced in up-down elastic movement. Therefore, through the above design improvement, the above structure not only simplifies the transmission structure of the beat movement mechanism, but also improves the convenience, reliability and comfort during use, while reducing maintenance costs and operating noise.

[0048] Specifically, referring to Figures 1 to 4 In the utility model embodiment, the driving mechanism 400 includes a driving component 410, a driving motor 420 and at least one rotating shaft 430, the driving component 410 is configured to be rotatable, and the driving component 410 is in transmission cooperation with the elastic transmission member 300; the driving motor 420 is arranged on the first frame body 100, the rotating shaft 430 includes a main shaft body 431 and an eccentric shaft body 432 eccentrically connected with the main shaft body 431, the main shaft body 431 is rotatably arranged on the first frame body 100 and is in transmission connection with the driving motor 420, and the eccentric shaft body 432 is connected with the driving component 410.

[0049] With the above structure, since the eccentric shaft body 432 is eccentrically connected with the main shaft body 431, when the driving motor 420 rotates, the eccentric shaft body 432 will move in the up-down direction, and this movement can be transmitted to the elastic transmission member 300 through the driving component 410, thereby realizing the up-down beat movement; through the transmission connection of the rotating shaft 430, the energy transmission efficiency of the driving motor 420 is high, energy loss is reduced, the structure is compact, and space is saved.

[0050] Specifically, referring to Figure 4In the embodiment of the utility model, the driving part 410 is a bearing, the inner ring of the bearing is connected with the eccentric shaft body 432, and the outer ring of the bearing is in abutment with the elastic transmission part 300.

[0051] Through the above structure, the abutment setting means that the outer ring of the bearing holds up the elastic transmission part 300 and the second frame body 200 to move up and down, and due to the gravity of the second frame body 200, the outer ring of the bearing and the elastic transmission part 300 always keep in contact without initial gap, and the close contact ensures that noise will not be produced due to the existence of the gap during transmission; the transmission becomes more stable, reduces the noise and wear caused by unstable transmission, and the elastic transmission part 300 can uniformly transmit force, reduces the local stress concentration caused by uneven force transmission, which also helps to reduce noise.

[0052] Since the output end of the driving mechanism 400 is directly in contact with the elastic transmission part 300, power can be efficiently and directly transmitted from the driving mechanism 400 to the elastic transmission part 300, and then transmitted to the second frame body 200 by the elastic transmission part 300, reducing energy loss; the abutment setting up and down simplifies the transmission path, reduces additional transmission components, makes the overall structure more compact, reduces manufacturing cost; the up-and-down movement mode is easier to control than rotation or other complex movement modes, so it can reduce noise and vibration caused by transmission. The elastic transmission part 300 can absorb and buffer the impact in the movement, further reducing noise; it helps to maintain transmission stability, reduces wear and transmission error, is convenient for adjustment and maintenance, and can adapt to different working environments and load requirements, because the elastic transmission part 300 can select different elastic coefficients and materials according to needs; prolongs the service life and improves reliability.

[0053] Of course, in some embodiments, the middle part of the elastic transmission part 300 is in the shape of a circular arc, one end of the elastic transmission part 300 is connected to the first frame body 100, the other end of the elastic transmission part 300 is connected to the second frame body 200, and the elastic transmission part 300 is driven by the driving part 410, the radius of the elastic transmission part 300 changes, and the up-and-down movement occurs, so in some embodiments, the inner ring of the bearing is connected with the eccentric shaft body 432, and the inner ring of the bearing is in abutment with the second frame body 200. It can be understood that the bearing holds up the second frame body 200 to move, because of the gravity of the second frame body 200, the second frame body 200 always keeps in contact with the bearing, which helps to reduce noise.

[0054] It can be understood that in the embodiment of the utility model, the width of the elastic transmission part 300 is greater than the width of the driving part 410.

[0055] With the above structure, the elastic transmission member 300 with a greater width can have a greater contact area with the driven component 410, so as to disperse the pressure, reduce the pressure per unit area, and reduce the abrasion; the greater contact area and better shock absorption performance help to reduce the noise in the transmission process. Similarly, the misalignment of the driven component 410 and the elastic transmission member 300 in the left-right direction is also prevented to a certain extent.

[0056] Of course, in some embodiments, the width of the elastic transmission member 300 can also be less than or equal to the width of the driven component 410, which is not limited herein; or in some embodiments, a positioning protrusion is arranged on one side wall of the elastic transmission member 300 facing the driven component 410, and the driven component 410 is located between the two positioning protrusions, so as to realize the pre-positioning of the driven component 410 and the elastic transmission member 300, and to facilitate the improvement of transmission reliability during transmission.

[0057] Specifically, referring to Figures 1 to 3 In the embodiment of the utility model, the elastic transmission member 300 is configured as an elastic sheet, which can provide up-down swing fixed elastic deformation, has good stability, is simpler in design, and is convenient to install and maintain

[0058] Of course, in some embodiments, the elastic transmission member 300 is configured as an elastic rod.

[0059] It should be noted that in the embodiment of the utility model, one end of the elastic transmission member 300 is fixedly connected to the first frame body 100, and the other end is fixedly connected to the second frame body 200. The above-mentioned elastic transmission member 300 can be fixedly connected to the first frame body 100 and the second frame body 200 in a bolt connection, buckle connection or the like, which is simple in structure, does not need to be hinged, and is convenient to disassemble and maintain.

[0060] Of course, in some other embodiments, one end of the elastic transmission member 300 is hingedly connected to the first frame body 100, and the other end is hingedly connected to the second frame body 200. The hinged mode can be selected as pin shaft hinging, bearing hinging or the like.

[0061] Specifically, referring to Figures 1 to 3 In the embodiment of the utility model, the driving mechanism 400 further comprises a running assembly 440, and the output shaft of the driving motor 420 is in transmission connection with the rotating shaft 430 through the running assembly 440.

[0062] With the above arrangement, the driving motor 420 as a centralized power source can conveniently control and adjust the running speed and power output of the whole system; the power of the driving motor 420 is transmitted to the rotating shaft 430 through the running assembly 440 (such as gears, belts, chains or the like), so as to realize effective energy transmission; and the whole driving mechanism 400 is more compact and saves space.

[0063] It should be noted that in the embodiment, the operating assembly 440 is a belt pulley structure, and of course, in other embodiments, it can also be a gear transmission, chain transmission, etc.

[0064] Specifically, referring to Figure 1 and Figure 3 In the embodiment of the utility model, the front and rear directions of the first frame body 100 are respectively provided with a pair of elastic transmission members 300; the rotating shafts 430 are two, and the two rotating shafts 430 are spaced apart in the front and rear directions and arranged on the first frame body 100; and the two ends of each rotating shaft 430 in the left and right directions are respectively provided with a driving component 410.

[0065] Among them, the linkage structure is arranged between the two rotating shafts 430 to link the two rotating shafts 430.

[0066] With the above structure, the linkage structure enables the two rotating shafts 430 to work synchronously, reduces the vibration and deviation caused by the asynchronization of the rotating shafts 430, and improves the stability and precision of the entire driving mechanism 400. Through the layout of the two rotating shafts 430 and the four driving components 410, the load can be more evenly distributed, the wear of a single component is reduced, the service life is prolonged, the overall reliability is improved, and the disassembly, assembly and maintenance are facilitated.

[0067] Of course, it should be noted that the number of rotating shafts 430 is not limited here and can be one, three, etc., which can be set accordingly as needed.

[0068] Specifically, referring to Figure 1 and Figure 3 In the embodiment of the utility model, the linkage structure includes two linkage pulleys 450 and a linkage belt 460 wound outside the two linkage pulleys 450.

[0069] Among them, the linkage pulley 450 is arranged in one-to-one correspondence with the rotating shaft 430 and is fixedly connected with the rotating shaft 430.

[0070] With the above structure, the linkage belt 460 is wound outside the two linkage pulleys 450, one of the linkage pulleys 450 rotates with the rotating shaft 430, thereby driving the other rotating shaft 430 to rotate through the other linkage pulley 450, so as to realize synchronous rotation; the combination of the linkage pulley 450 and the belt provides an efficient energy transmission path, reduces energy loss; the belt transmission noise is low; the maintenance is relatively simple, the cost is relatively low, the structure is relatively compact, the space utilization rate is high, in addition, the linkage belt 460 can compensate for the slight change of the shaft spacing to a certain extent, and the transmission flexibility is increased.
