Description

Technical Field

[0001] This application relates to the field of furniture technology, and in particular to rhythmic furniture. Background Technology

[0002] Rhythmic furniture generally includes a base, a support frame, and a drive mechanism. The base is typically placed on the ground for support, the support frame is positioned above the base, and the drive mechanism is connected to the support frame, driving it to reciprocate. The "rhythm" refers to this reciprocating motion of the support frame. Based on the direction of the support frame's rhythmic movement, it can be categorized as horizontal rhythm, vertical rhythm, and vertical-horizontal rhythm. Vertical-horizontal rhythm means that in a piece of rhythmic furniture, the support frame can perform both horizontal and vertical rhythms; some pieces can even perform both simultaneously. A piece of rhythmic furniture capable of both vertical and horizontal rhythms includes a first motor for horizontal movement and a second motor for vertical movement. The output of the second motor is connected to the first motor, and the output of the first motor is connected to the support frame. That is, the vertical movement output by the second motor is converted into the vertical movement of the first motor, causing the support frame connected to the first motor to move vertically. When the first motor outputs horizontal movement, the support frame connected to the first motor's output moves horizontally, thus completing the movement of the entire rhythmic furniture in both vertical and horizontal dimensions. Since the first motor also needs to move up and down under the drive of the second motor, a more complex structure is required to fix the first motor to meet the connection strength requirements. Utility Model Content

[0003] The rhythmic furniture provided in this application aims to at least solve the technical problem of complex connections in the mechanisms responsible for outputting horizontal movement in existing rhythmic furniture.

[0004] A first aspect of this application provides a rhythmic furniture, comprising: a fixed frame, a rhythmic frame, a vertical drive mechanism, and a horizontal drive mechanism. The vertical drive mechanism includes a first motor, a first transmission structure, a first motion structure, and a first elastic structure. The first motor is connected to the first motion structure via the first transmission structure. The first transmission structure is configured to convert the rotational motion output by the first motor into reciprocating motion of the first motion structure at least in the vertical direction. The first motor is disposed on the fixed frame. The first motion structure is connected to the rhythmic frame via the first elastic structure, which includes an elastic deformation space at least in the horizontal direction. The horizontal drive mechanism includes a second motor, a second transmission structure, a second motion structure, and a second elastic structure. The second motor is connected to the second motion structure via the second transmission structure. The second transmission structure is configured to convert the rotational motion output by the second motor into reciprocating motion of the second motion structure at least in the horizontal direction. The second motor is disposed on the fixed frame. The second motion structure is connected to the rhythmic frame via the second elastic structure, which includes an elastic deformation space at least in the vertical direction.

[0005] The rhythmic furniture according to the embodiments of this application has at least the following beneficial effects:

[0006] The second motor responsible for horizontal movement and the first motor responsible for vertical (up and down) movement are both mounted on a fixed frame. The vertical movement output by the first motor directly drives the rhythm frame and does not drive the second motor to perform vertical (up and down) movement. Therefore, the connection strength requirement of the second motor is reduced, making the design of the entire horizontal drive mechanism simpler.

[0007] In one possible implementation, the vertical drive mechanism further includes a first support frame, which is connected to the first motion structure and to the first elastic structure, allowing the rhythm frame to be suspended from the first support frame via the first elastic structure. The first support frame enhances the connection strength between the first motion structure and the rhythm frame. Connecting the first support frame and the rhythm frame via suspension reduces the bending resistance requirement on the first elastic structure, simplifying the design.

[0008] In one possible implementation, the first elastic structure includes a first spring sheet, which has a first upper end located above and a first lower end located below. The first upper end is connected to the first support frame, and the first lower end is connected to the rhythm frame, so that the first support frame is suspended from the rhythm frame. By configuring the first spring sheet as a sheet, the first spring sheet is thinner in the horizontal direction, making it easier to deform, and the first spring sheet has good tensile strength along its length or width.

[0009] In one possible implementation, the second elastic structure includes a second spring sheet whose thickness direction is parallel to the vertical direction. The two ends of the second spring sheet along its width direction are respectively connected to the rhythm frame and the second motion structure. This allows the second spring sheet to have a stronger resistance to tensile curling when subjected to force along its width direction.

[0010] In one possible implementation, the first transmission structure includes a first motion conversion structure, a first connecting member, a first rotating rod, a second connecting member, and a second rotating rod. The first motion conversion structure is connected to the first motor and the first connecting member, respectively. The first motion conversion structure is used to convert the rotational motion output by the first motor into reciprocating motion of the first connecting member in at least the horizontal direction. The first connecting member is eccentrically connected to the first rotating rod, and the first rotating rod is rotatably connected to the fixed frame. The second connecting member is fixedly connected to the first rotating rod, and the second connecting member is rotatably connected to the second rotating rod. The second rotating rod is fixedly connected to the first motion structure.

[0011] In one possible implementation, the first transmission structure further includes a third spring plate extending in a horizontal direction, the third spring plate including at least an elastic deformation space in a vertical direction, and the third spring plate being fixedly connected to the first connector and the first rotating rod respectively.

[0012] In one possible implementation, the first, second, and third springs are all made of spring steel. Using spring steel for the springs simplifies the structure of the rhythmic furniture.

[0013] In one possible implementation, the first support frame includes a first top surface, and the rhythmic frame includes a second upper end and a second lower end opposite each other in the vertical direction. The second upper end includes the second top surface, and the second lower end is connected to a first elastic structure. In the vertical direction, the first top surface is lower than the second top surface. This facilitates the subsequent installation of soft furnishings (such as mattresses) for the rhythmic furniture.

[0014] A second aspect of this application provides a rhythmic furniture system, including a fixed frame, a rhythmic frame, a vertical drive mechanism, and a horizontal drive mechanism. The vertical drive mechanism includes a third motor, a third transmission structure, a third motion structure, and a vertical limiting structure. The third motor is disposed on the fixed frame. The third transmission structure is connected to both the third motor and the third motion structure. The third transmission structure converts the rotational motion output by the third motor into reciprocating motion of the third motion structure, at least in the vertical direction. The third motion structure is connected to the rhythmic frame via the vertical limiting structure. The vertical limiting structure restricts the relative displacement between the third motion structure and the rhythmic frame in the vertical direction and prevents the third motion structure from... The horizontal drive mechanism includes a fourth motor, a fourth transmission structure, a fourth motion structure, and a horizontal limiting structure. The fourth motor is mounted on the fixed frame. The fourth transmission structure is connected to both the fourth motor and the fourth motion structure. The fourth transmission structure converts the rotational motion output by the fourth motor into reciprocating motion of the fourth motion structure, at least in the horizontal direction. The fourth motion structure is connected to the rhythm frame via the horizontal limiting structure. The horizontal limiting structure restricts the relative displacement between the fourth motion structure and the rhythm frame in the horizontal direction and allows the relative displacement between the fourth motion structure and the rhythm frame in the vertical direction.

[0015] The rhythmic furniture according to the embodiments of this application has at least the following beneficial effects:

[0016] By mounting both the third motor of the vertical drive mechanism and the fourth motor of the horizontal drive mechanism on a fixed frame, and with both the fourth motor responsible for horizontal movement and the third motor responsible for vertical (up and down) movement on the fixed frame, the vertical movement output by the third motor directly drives the rhythm frame without driving the fourth motor to perform vertical (up and down) movement. This reduces the connection strength requirement of the fourth motor and simplifies the design of the entire vertical drive mechanism.

[0017] In one possible implementation, the vertical limiting structure includes a first bearing assembly and a horizontal slide groove. The first bearing assembly is disposed within the horizontal slide groove, which is fixedly connected to the rhythm frame. The first bearing assembly is rotatably connected to the third motion structure. The horizontal limiting structure also includes a second bearing assembly and a vertical slide groove. The second bearing assembly is disposed within the vertical slide groove, which is fixedly connected to the rhythm frame. The second bearing assembly is rotatably connected to the fourth motion structure. The cooperation between the bearings and the slide grooves makes the movement of the rhythm frame smoother and reduces jerking. Attached Figure Description

[0034] The first aspect of this application provides rhythmic furniture. Figure 1 This is a schematic diagram of a rhythmic furniture provided in an embodiment of this application. Figure 2 This is an exploded view of the rhythmic furniture, including a fixed frame 100, a rhythmic frame 200, a vertical drive mechanism 300, and a horizontal drive mechanism 400. Figure 3 and Figure 4 As shown, the vertical drive mechanism 300 includes a first motor 310, a first transmission structure 320, a first motion structure 330, and a first elastic structure 340. The first motor 310 is connected to the first motion structure 330 via the first transmission structure 320. The first transmission structure 320 is configured to convert the rotational motion output by the first motor 310 into reciprocating motion of the first motion structure 330, at least in the vertical direction. The first motor 310 is mounted on the fixed frame 100. The first motion structure 330 is connected to the rhythm frame 200 via the first elastic structure 340. The first elastic structure 340 includes an elastic deformation space at least in the horizontal direction. Figure 5As shown, the horizontal drive mechanism 400 includes a second motor 410, a second transmission structure 420, a second motion structure 430, and a second elastic structure 440. The second motor 410 is connected to the second motion structure 430 via the second transmission structure 420. The second transmission structure 420 is configured to convert the rotational motion output by the second motor 410 into reciprocating motion of the second motion structure 430, at least in the horizontal direction. The second motor 410 is mounted on the fixed frame 100. The second motion structure 430 is connected to the rhythm frame 200 via the second elastic structure 440, which includes an elastic deformation space at least in the vertical direction. In related technologies, the motor responsible for vertical motion needs to drive the motor responsible for horizontal motion and the rhythm frame; that is, the motor responsible for horizontal motion needs to move vertically together with the rhythm frame. This places high demands on the connection strength of the motor responsible for horizontal motion. In the embodiments of this application, the second motor 410 responsible for the horizontal movement direction and the first motor 310 responsible for the vertical (up and down) movement direction are both mounted on the fixed frame 100. The vertical movement output by the first motor 310 directly drives the rhythm frame 200 and does not drive the second motor 410 to perform vertical (up and down) movement. Therefore, the connection strength requirement of the second motor 410 is reduced, making the design of the entire horizontal drive mechanism 400 simpler.

[0035] After both the first motor 310 and the second motor 410 are mounted on the fixed frame 100, the problem that arises is the interference between the different motion directions output by the first motor 310 and the second motor 410. That is, the rhythm frame 200 is connected to both the first motion structure 330 and the second motion structure 430. When the first motion structure 330 outputs vertical motion, the rhythm frame 200 moves vertically. If the rhythm frame 200 and the second motion structure 430 are fixedly connected, the rhythm frame 200 will also drive the second motion structure 430 to move vertically. At this time, it is opposite to the normal horizontal output of the second motion structure 430, which will cause interference with the second motion structure 430. This will hinder the vertical motion output by the first motion structure 330 or damage the connection structure between the rhythm frame 200 and the first motion structure 330 or the second motion structure 430. In this application, a first elastic structure 340 with horizontal deformation space and a second elastic structure 440 with vertical deformation space are provided. The first elastic structure 340 is connected to both the first motion structure 330 and the rhythm frame 200, allowing the first motion structure 330 and the rhythm frame 200 to have relative displacement space in the horizontal direction. When the rhythm frame 200 moves horizontally under the drive of the second motion structure 430, the rhythm frame 200 causes the first elastic structure 340 to deform horizontally, resulting in relative displacement of the rhythm frame 200 relative to the first motion structure 330. This prevents the rhythm frame 200 from causing horizontal displacement of the first motion structure 330, thereby preventing damage to the connection mechanism between the first motion structure 330 and the first transmission structure 320. Similarly, the second elastic structure 440 also allows for a vertical displacement relationship between the rhythm frame 200 and the second motion structure 430. It is understandable that the first elastic structure 340 can transmit the vertical reciprocating motion output by the first motion structure 330 to the rhythm frame 200, so that the rhythm frame 200 also produces a vertical reciprocating motion; the second elastic structure 440 can transmit the horizontal reciprocating motion output by the second motion structure 430 to the rhythm frame 200, so that the rhythm frame 200 also produces a horizontal reciprocating motion.

[0036] Furthermore, such as Figure 4 As shown, the first moving structure 330 is a rigid component extending in the vertical direction, and the material can be, for example, stainless steel.

[0037] Furthermore, such as Figure 2 , Figure 3 and Figure 6As shown, the vertical drive mechanism 300 also includes a first support frame 350, which is connected to the first motion structure 330 and to the first elastic structure 340, and is suspended from the rhythm frame 200 via the first elastic structure 340. The first support frame 350 enhances the connection between the first motion structure 330 and the rhythm frame 200. Connecting the first support frame 350 and the rhythm frame 200 via suspension reduces the bending resistance requirement on the first elastic structure 340, simplifying the design.

[0038] Furthermore, the rhythm frame 200 is a rectangular frame in the horizontal direction, and the first support frame 350 is also a rectangular frame in the horizontal direction. The height of the part where the first elastic structure 340 is connected to the first support frame 350 is higher than the height of the part where the first elastic structure 340 is connected to the rhythm frame 200, so that the rhythm frame 200 is suspended on the first support frame 350.

[0039] Furthermore, such as Figure 3 As shown, the first elastic structure 340 includes a first spring piece 341 extending vertically. The first spring piece 341 includes an upper end 3411 located above and a lower end 3412 located below. The upper end 3411 is connected to the first support frame 350, and the lower end 3412 is connected to the rhythm frame 200, thereby suspending the rhythm frame 200 from the first support frame 350. The first spring piece 341 is generally sheet-shaped, meaning its length and width are much greater than its thickness. The first spring piece 341 includes two opposite ends along its length, one end connected to the first support frame 350 and the other end connected to the rhythm frame 200, wherein the end connected to the first support frame 350 is higher than the end connected to the rhythm frame 200. Alternatively, along the width direction of the first elastic piece 341, one end is connected to the first support frame 350, and the other end is connected to the rhythm frame 200. The end connected to the first support frame 350 is higher than the end connected to the rhythm frame 200, thus allowing the first elastic piece 341 to have a certain range of deformation space in the horizontal direction while the rhythm frame 200 is suspended from the first support frame 350. By setting the first elastic piece 341 as a sheet, its thickness in the horizontal direction is relatively thin, making deformation easier. Furthermore, the first elastic piece 341 has good tensile strength along its length or width direction. When the first support frame 350 moves upward, it can drive the rhythm frame 200 to move upward; when the first support frame 350 moves downward, the rhythm frame 200 moves downward under the combined action of gravity and the first support frame 350. This process repeats, enabling the rhythm frame 200 to reciprocate vertically.

[0040] Furthermore, continue to refer to Figure 3The first elastic structure 340 further includes a fixing structure 342, which passes through the first upper end 3411 of the first spring piece 341 along its thickness direction and is connected to the first support frame 350. The fixing structure 342 includes a bolt, the first upper end 3411 of the first spring piece 341 has an opening for the bolt to pass through, and the first support frame 350 has a screw hole adapted to the bolt. Furthermore, the first elastic structure 340 also includes a noise-reducing pad, which is disposed between the first spring piece 341 and the first support frame 350 and abuts against both. The noise-reducing pad has an opening for the bolt to pass through, reducing friction noise between the first spring piece 341 and the first support frame 350 when the first spring piece 341 undergoes elastic deformation, thus improving the user's riding experience. The noise-reducing pad can be a rubber pad, a silicone pad, etc.

[0041] Furthermore, such as Figure 1 As shown, the length direction of the first support frame 350 is parallel to the length direction of the rhythm frame 200. Along the length direction of the first support frame 350, the first support frame 350 includes a front end and a rear end, and the rhythm frame 200 also includes a front end and a rear end. There are two first elastic elements, which are respectively installed at the front end and rear end of the first support frame 350 and the front end and rear end of the rhythm frame 200. The thickness direction of the first elastic element is parallel to the length direction of the first support frame 350. The horizontal movement direction of the second motion structure 430 is parallel to the length direction of the first support frame 350, that is, the rhythm frame 200 moves horizontally back and forth along the length direction of the rhythm frame 200 (the length direction of the first support frame 350).

[0042] Furthermore, such as Figure 5 As shown, the second elastic structure 440 includes a second spring sheet 441. The thickness direction of the second spring sheet 441 is parallel to the vertical direction. The second spring sheet 441 is connected to the second motion structure 430 and the rhythm frame 200. By providing the second spring sheet 441, since its thickness direction is parallel to the vertical direction, it is easy to deform in the thickness direction, so that the second spring sheet 441 has a certain range of deformation space in the vertical direction, which meets the relative displacement requirements of the rhythm frame 200 and the second motion structure 430 in the vertical direction. The second spring sheet 441 includes two opposite ends along its width direction, one end of which is connected to the rhythm frame 200 and the other end of which is connected to the second motion structure 430. By connecting the end that is the long side to the rhythm frame 200 and the second motion structure 430, the second spring sheet 441 has a stronger tensile curling resistance when subjected to force in the width direction.

[0043] Furthermore, the second motion structure 430 moves in a horizontal direction parallel to the width direction of the second spring 441, which is mounted on one end of the rhythm frame 200 where the short side is located.

[0044] Furthermore, the second elastic structure 440 also includes a fixing structure 342, which is fixed in the same way as the first elastic structure 340, using bolts for fixing. Furthermore, the second elastic structure 440 also includes a sound-absorbing pad, the structure, material, and installation method of which are the same as those of the first elastic structure 340, and will not be repeated here.

[0045] Furthermore, such as Figure 3 and Figure 4The first transmission structure 320 includes a first motion conversion structure 321, a first connecting member 322, a first rotating rod 323, a second connecting member 324, and a second rotating rod 325. The first motion conversion structure 321 is connected to the first motor 310 and the first connecting member 322, respectively. The first motion conversion structure 321 is used to convert the rotational motion output by the first motor 310 into reciprocating motion of the first connecting member 322 in at least the horizontal direction. The first connecting member 322 is eccentrically connected to the first rotating rod 323, and the first rotating rod 323 is rotatably connected to the fixed frame 100. The second connecting member 324 is fixedly connected to the first rotating rod 323, and the second connecting member 324 is rotatably connected to the second rotating rod 325. The second rotating rod 325 is fixedly connected to the first motion structure 330. The first motor 310 converts the rotational motion output by the first motor 310 into reciprocating motion in the horizontal direction through the first motion conversion structure 321, thereby driving the first connecting member 322 to perform reciprocating motion in the horizontal direction. The first connecting member 322 is eccentrically connected to the first rotating rod 323. Since the first connecting member 322 moves horizontally, it outputs a torque along the tangential direction of the first rotating rod 323, causing the first rotating rod 323 to rotate along its axis. This causes the second connecting member 324, connected to the first rotating rod 323, to rotate about the axis of the first rotating rod 323, resulting in a vertical height change at the end of the second connecting member 324 furthest from the first rotating rod 323. Simultaneously, since the second connecting member 324 and the second rotating rod 325 are only rotatably connected, the second rotating rod 325 also moves up and down when the second connecting member 324 moves up and down. Furthermore, the second rotating rod 325 is fixedly connected to the first moving structure 330, so the first moving structure 330 also moves up and down. Since the second rotating rod 325 and the second connecting member 324 are rotatably connected, the first moving structure 330, fixedly connected to the second rotating rod 325, performs a vertical translational movement. This allows the first support frame 350 to change height through translation rather than rotation, ensuring that the occupant of the rhythmic furniture maintains a consistent posture at all times. By converting the horizontal movement of the first connecting member 322 into the vertical movement of the first support frame 350, the vertical drive mechanism 300 occupies less space in terms of height, thereby lowering the center of gravity of the first support frame 350 and the rhythmic frame 200, resulting in better stability of the rhythmic furniture during high-frequency reciprocating movements.

[0046] It is understandable that the eccentric connection between the first connecting piece 322 and the first rotating rod 323 means that the horizontal plane where the first connecting piece 322 moves in the horizontal direction and the horizontal plane where the axis of the first rotating rod 323 is located are staggered in the vertical direction. The use of the first rotating rod 323 results in higher overall structural strength for the rhythmic furniture, and better stability during the high-frequency up-and-down reciprocating movements of the first support frame 350 and the rhythmic frame 200.

[0047] Furthermore, such as Figure 1 As shown, the fixed frame 100 is rectangular in shape, and its length is parallel to the length of the first support frame 350 and the rhythm frame 200. The first support frame 350 and the rhythm frame 200 are generally positioned above the fixed frame 100. The fixed frame 100 also includes four support legs 110 for contacting the ground.

[0048] Furthermore, such as Figure 3 and Figure 4 As shown, the first rotating rod 323 and the second rotating rod 325 are cylindrical in shape, and their axial directions are parallel to the width direction of the first support frame 350. Figure 2 As shown, the fixed frame 100 also includes connecting seats 120. The two connecting seats 120 are respectively disposed at both ends of the first rotating rod 323 and are rotatably connected to the first rotating rod 323. The two connecting seats 120 are respectively fixed on the long side of the fixed frame 100. By setting the rod-shaped first rotating rod 323, the overall stability of the rhythmic furniture is ensured.

[0049] Furthermore, there are two second connecting members 324, which are disposed at both ends of the first rotating rod 323 along the axial direction of the first rotating rod 323, thereby enhancing the connection structure strength between the first rotating rod 323 and the second rotating rod 325.

[0050] Furthermore, along the length of the fixed frame 100, the fixed frame 100 includes a front end and a rear end. The first rotating rod 323 is set at the front end of the fixed frame 100. The first rotating rod 323, the two second connecting pieces 324, and the second rotating rod 325 set at the front end of the fixed frame 100 are regarded as a group. Similarly, at the rear end of the fixed frame 100, such a group of connection structures is also provided between the fixed frame 100 and the first support frame 350 to improve the structural strength between the fixed frame 100 and the first support frame 350, so as to match the high-frequency rhythm of the first support frame 350.

[0051] It is understood that the first connecting member 322 is eccentrically connected to the first rotating rod 323 located at the front end of the fixed frame 100. In order to improve the uniformity of the front and rear end movement, the first transmission structure 320 may also include two first connecting members 322. Both first connecting members 322 are connected to the first motion conversion structure 321. One of the first connecting members 322 is eccentrically connected to the first rotating rod 323 located at the front end of the fixed frame 100, and the other first connecting member 322 is eccentrically connected to the first rotating rod 323 located at the rear end of the fixed frame 100.

[0052] Furthermore, such as Figure 4 As shown, the first motion conversion structure 321 is a cam 3212 slider conversion structure. The first motion conversion structure 321 includes a belt 3211, a cam 3212, and an annular driven sleeve 3213. The cam 3212 is sleeved inside the annular driven sleeve 3213. The first motor 310 is connected to the cam 3212 through the first belt 3211. The protrusion of the cam 3212 abuts against the inner wall of the annular driven sleeve 3213. When the cam 3212 rotates, it drives the annular driven sleeve 3213 to move horizontally. Further, the first motion conversion structure 321 includes two sets of cams 3212 and annular driven sleeves 3213. One annular driven sleeve 3213 is connected to the first connecting member 322 located at the front end of the fixed frame 100, and the other annular driven sleeve 3213 is connected to the first connecting member 322 located at the rear end of the fixed frame 100.

[0053] Furthermore, the first motion conversion structure 321 also includes a fourth spring 3214, and the first connector 322 is connected to the annular driven sleeve 3213 through the fourth spring 3214 to reduce the stress between the annular driven sleeve 3213 and the first connector 322.

[0054] Furthermore, the connection between the first rotating rod 323 and the second connecting member 324 is a slotted key connection to increase the stability of their connection.

[0055] Furthermore, such as Figure 3 and Figure 4 As shown, the second rotating rod 325 is rotatably connected to the second connecting member 324, and the second rotating rod 325 is fixedly connected to the first moving structure 330.

[0056] Furthermore, such as Figure 2 and Figure 4 As shown, the rotatable connection between the first rotating rod 323 and the connecting seat 120 is a bearing connection, and the rotatable connection between the second rotating rod 325 and the second connecting piece 324 is also a bearing connection to reduce rotational friction. Furthermore, the bearings used for the bearing connection are rubber-coated bearings to reduce noise from rotational friction, providing users of the rhythmic furniture with a quieter user experience.

[0057] For further information, please continue to refer to [link / reference]. Figure 3 and Figure 4 The first transmission structure 320 also includes a third spring 326, which extends horizontally and includes at least a vertically elastic deformation space. The third spring 326 is fixedly connected to the first connector 322 and the first rotating rod 323. The third spring 326 provides a buffering effect when the positions of the first connector 322 and the first rotating rod 323 change periodically, thus reducing the user's sense of jerkiness when the rhythmic furniture changes direction, thereby improving the user experience.

[0058] In some embodiments, the first connector 322 includes a rack, and the circumferential sidewall of the first rotating rod 323 includes circumferentially distributed teeth. The horizontal plane on which the rack is located is different from the horizontal plane on which the axis of the first rotating rod 323 is located, i.e., eccentric connection. The rack and the teeth are meshed to convert the horizontal motion output by the first connector 322 into the rotational motion of the first rotating rod 323.

[0059] Furthermore, the first spring piece 341, the second spring piece 441, the third spring piece 326, and the fourth spring piece 3214 are all made of spring steel. Using spring steel to make the spring pieces makes the structure of the rhythmic furniture simpler.

[0060] Furthermore, such as Figure 6 As shown, the first support frame 350 includes a first top surface 351, and the rhythm frame 200 includes a second upper end 210 and a second lower end 220 that are opposite each other in the vertical direction. The second upper end 210 includes a second top surface 211, and the first lower end 3412 is connected to the first elastic structure 340. In the vertical direction, the first top surface 351 is lower than the second top surface 211. The second top surface 211 corresponds to the rhythm frame 200, which can simultaneously complete vertical and horizontal movements. The second top surface 211 of the rhythm frame 200 extends vertically beyond the first top surface 351 of the first support frame 350, making it more convenient to install soft furnishings (such as mattresses) for rhythmic furniture later.

[0061] Furthermore, such as Figure 5 As shown, the second transmission structure 420 includes a second motion conversion structure, which is the same as the first motion conversion structure 321, and will not be repeated here. The first motion conversion structure 321 and the second motion structure 430 are connected by a spring.

[0062] Furthermore, the second motion structure 430 is a rigid plate, such as stainless steel, which extends horizontally and its length extends along the length of the rhythm frame 200.

[0063] It is understood that the rhythmic furniture also includes a power supply device and a control device. The first motor 310 and the second motor 410 are powered by the power supply device, and the first motor 310 and the second motor 410 are controlled by the control device. The control device is configured to include a first control mode, a second control mode and a third control mode. When the control device is in the first control mode, the control device controls the power supply device to supply power to the first motor 310; when the control device is in the second control mode, the control device controls the power supply device to supply power to the second motor 410; when the control device is in the third control mode, the control device controls the power supply device to supply power to both the second motor 410 and the first motor 310 simultaneously.

[0064] The second aspect of this application provides a rhythmic furniture, the main difference from the first aspect being that a vertical limiting structure is used instead of the first elastic structure in the first aspect, and a horizontal limiting structure is used instead of the second elastic structure in the first aspect.

[0065] Specifically, the rhythmic furniture includes a fixed frame, a rhythmic frame, a vertical drive mechanism, and a horizontal drive mechanism. The vertical drive mechanism includes a third motor, a third transmission structure, a third motion structure, and a vertical limiting structure. The third motor is mounted on the fixed frame. The third transmission structure is connected to both the third motor and the third motion structure. The third transmission structure converts the rotational motion output by the third motor into reciprocating motion of the third motion structure, at least in the vertical direction. The third motion structure is connected to the rhythmic frame via the vertical limiting structure. The vertical limiting structure restricts the relative displacement between the third motion structure and the rhythmic frame in the vertical direction and ensures that the third motion structure... The rhythm frame can generate relative displacement in the horizontal direction. The horizontal drive mechanism includes a fourth motor, a fourth transmission structure, a fourth motion structure, and a horizontal limiting structure. The fourth motor is mounted on the fixed frame. The fourth transmission structure is connected to both the fourth motor and the fourth motion structure. The fourth transmission structure converts the rotational motion output by the fourth motor into reciprocating motion of the fourth motion structure, at least in the horizontal direction. The fourth motion structure is connected to the rhythm frame through the horizontal limiting structure, which restricts the relative displacement between the fourth motion structure and the rhythm frame in the horizontal direction and allows relative displacement between them in the vertical direction. By mounting both the third motor of the vertical drive mechanism and the fourth motor of the horizontal drive mechanism on the fixed frame, and both the fourth motor responsible for horizontal motion and the third motor responsible for vertical (up-down) motion being mounted on the fixed frame, the vertical motion output by the third motor directly drives the rhythm frame without driving the fourth motor for vertical (up-down) motion. This reduces the connection strength requirement of the fourth motor and simplifies the design of the entire vertical drive mechanism.

[0066] Furthermore, the vertical limiting structure includes a first bearing assembly and a horizontal slide groove. The first bearing assembly is disposed within the horizontal slide groove, which is fixedly connected to the rhythm frame. The first bearing assembly is rotatably connected to the third motion structure. The horizontal limiting structure also includes a second bearing assembly and a vertical slide groove. The second bearing assembly is disposed within the vertical slide groove, which is fixedly connected to the rhythm frame. The second bearing assembly is rotatably connected to the fourth motion structure. The cooperation between the bearings and the slide grooves makes the movement of the rhythm frame smoother and reduces jerking.

[0067] In some embodiments, the vertical limiting structure includes a first ring and a first rod. The first rod is disposed on the rhythm frame, and the first ring is disposed on the third motion structure. The first rod extends along the horizontal movement direction of the rhythm frame and passes through the first ring. The axis of the first rod is parallel to the axis of the first ring. The horizontal limiting structure includes a second ring and a second rod. The second rod is disposed on the rhythm frame, and the second ring is disposed on the fourth motion structure. The first rod extends vertically, and the second rod passes through the second ring. The axis of the second rod is parallel to the axis of the second ring.
