[0003] In the related art, the rhythmic furniture includes a fixed frame, a moving frame, a driving mechanism and a connecting structure connecting the moving frame and the fixed frame. The fixed frame is installed on the ground to support the moving frame. The moving frame is installed above the fixed frame through the connecting structure. The moving frame is used to install the furniture cushion. The driving mechanism includes a motor and a transmission mechanism. The motor is installed on the fixed frame. The power output end of the motor is connected to the moving frame through the transmission mechanism. The transmission mechanism converts the rotary motion output by the motor into reciprocating motion, so that the moving frame reciprocates relative to the fixed frame.

[0007] A fixed frame, the fixed frame is used to support the movable frame;
[0008] The electromagnetic drive mechanism includes a magnetic moving component and a coil component, one of which is connected to the moving frame and the relative position remains unchanged, and the other is connected to the fixed frame and the relative position remains unchanged. The magnetic moving component includes a permanent magnet, and the permanent magnet includes a channel hole opened in the horizontal direction. The coil component includes a wire coil, which is formed by winding a wire and extending in the horizontal direction to generate a magnetic field with a changed magnetic pole. The wire coil is partially arranged in the channel hole, and the wire coil includes a first end and a second end opposite to each other in the horizontal direction, the first end is located in the channel hole, and the second end is located outside the channel hole.
[0009] The rhythmic furniture according to the embodiment of the present application has at least the following beneficial effects:
[0010] The rhythmic furniture of the present application embodiment does not need to set a cam structure to convert between rotational motion and reciprocating motion, which reduces the noise generated during the operation of the rhythmic furniture. At the same time, the wire coil is partially set in the channel hole of the permanent magnet, so that the permanent magnet can be designed to be larger and more magnetic, so that the wire coil can be designed to be smaller, thereby reducing the heat generated by the wire coil during the movement of the rhythmic furniture.
[0011] In a possible implementation, the magnetic moving assembly is connected to the moving frame, and the coil assembly is connected to the fixed frame, so as to avoid problems such as wire entanglement caused by the movement of the coil assembly.

The first metal gasket makes the magnetic field lines of the permanent magnet more concentrated, concentrated at the first metal gasket, and increases the magnetic force between the permanent magnet and the wire coil.
[0013] In a possible implementation, the first metal gasket includes a circular first hole, the wire coil is passed through the first hole, and the diameter of the first hole is smaller than the diameter of the channel hole. The diameter of the first hole is smaller than the diameter of the channel hole, so that the magnetic field lines of the permanent magnet are further concentrated, thereby increasing the magnetic force between the permanent magnet and the wire coil.

By arranging the second metal sheet at the end of the permanent magnet away from the wire coil, the magnetic field lines of the permanent magnet are more concentrated, thereby increasing the magnetic force between the permanent magnet and the wire coil.
[0015] In a possible embodiment, the second metal gasket further includes an extension portion, the extension portion extends from the fifth end face toward the permanent magnet, the extension portion is a cylinder extending in the horizontal direction, the axis of the extension portion coincides with the axis of the permanent magnet, and the wire coil includes a first inner cavity opening toward the permanent magnet, the first inner cavity is used to accommodate the extension portion.

[0017] In a possible implementation, the end of the extension portion away from the main body is disposed between the first end and the second end of the wire coil. The extension portion is located in the wire coil, which is conducive to making the magnetic field generated by the permanent magnet and the magnetic field generated by the wire coil more uniform.
[0018] In a possible implementation, the coil assembly further includes a receiving member, the receiving member is disposed in the first inner cavity, the receiving member is a cylinder extending in the horizontal direction, the receiving member is provided with a second inner cavity opening toward the permanent magnet, the second inner cavity is used to accommodate at least part of the extension portion, the outer circumferential surface of the receiving member is recessed inwardly in the circumferential direction to form a slot, and the wire coil is disposed in the slot. The wire coil is fixed by providing the slot so that the wire coil does not move along the axial direction of the wire coil.
[0019] In a possible implementation, the height of the wire coil in the radial direction does not exceed the outer circumference of the receiving member.

[0035] In the description of this embodiment, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this embodiment based on the specific content of the technical solution.
[0036] Please refer to Figure 1 The rhythmic furniture provided in the present application includes a moving frame 1, a fixed frame 2 and an electromagnetic drive mechanism 3. The fixed frame 2 is generally installed on the ground to support the moving frame 1. In some embodiments, the moving frame 1 includes a frame-shaped main body and four supporting legs. The moving frame 1 is used to install furniture cushions. The shape of the moving frame 1 can be selected according to the type of furniture. In this embodiment, the shape of the moving frame 1 is frame-shaped. The electromagnetic drive mechanism 3 includes a magnetic component 31 and a coil component 32. One of the magnetic component 31 and the coil component 32 is connected to the moving frame 1 and the relative position remains unchanged, and the other is connected to the fixed frame 2 and the relative position remains unchanged. Please continue to refer to Figure 2 , Figure 3 and Figure 4 The magnetic moving assembly 31 includes a permanent magnet 311, the permanent magnet 311 includes a channel hole 3111 opened in the horizontal direction, and the coil assembly 32 includes a wire coil 321, which is formed by winding a wire and extending in the horizontal direction, and is used to generate a magnetic field with a magnetic pole change. The wire coil 321 is partially arranged in the channel hole 3111. Please continue to refer to Figure 5 The wire coil 321 includes a first end 3211 and a second end 3212 that are opposite to each other in the horizontal direction, the first end 3211 is located inside the channel hole 3111, and the second end 3212 is located outside the channel hole 3111. The rhythmic furniture provided in this embodiment does not need to be provided with a cam structure to convert between rotary motion and reciprocating motion because the electromagnetic drive mechanism 3 directly outputs reciprocating motion, thereby reducing the noise generated during the operation of the rhythmic furniture. At the same time, the wire coil 321 is partially provided in the channel hole 3111 of the permanent magnet 311, so that the permanent magnet 311 can be designed to be larger and more magnetic, so that the wire coil 321 can be designed to be smaller, so as to reduce the heat generated by the wire coil 321 during the movement of the rhythmic furniture.
[0037] It can be understood that the permanent magnet 311 includes a channel hole 3111 opened in the horizontal direction, and the wire coil 321 is partially arranged in the channel hole 3111. After the wire coil 321 is energized, the wire coil 321 will generate a magnetic field. Since the permanent magnet 311 will also generate a magnetic field, and the wire coil 321 is partially arranged in the channel hole 3111 of the permanent magnet 311, a magnetic field force will be generated between the permanent magnet 311 and the wire coil 321. One of the permanent magnet 311 and the wire coil 321 is fixed on the fixed frame 2, and the other is fixed on the movable frame 1. The one fixed on the fixed frame 2 remains unchanged, and the other generates a displacement in the horizontal direction under the action of the magnetic field force, which is recorded as the wire coil 321 moving away from the permanent magnet 311, and then the other drives the movable frame 1 to move. After the direction of the current flowing through the wire coil 321 is changed, the direction of the magnetic field generated by the wire coil 321 changes, and the direction of the magnetic field force generated between the wire coil 321 and the permanent magnet changes in the opposite direction to the previous direction. At this time, it is recorded that the wire coil 321 moves close to the permanent magnet 311, thereby driving the movable frame 1 to move in the opposite direction to the previous direction. By changing the direction of the current flowing through the wire coil 321, the movable frame 1 can achieve reciprocating switching movement in two opposite horizontal directions relative to the fixed frame 2, that is, reciprocating movement.
[0038] In some embodiments, the magnetic moving assembly 31 is connected to the moving frame 1, and the coil assembly 32 is connected to the fixed frame 2. Connecting the coil assembly 32 to the fixed frame 2 makes the wiring between the coil assembly 32 and the power supply more convenient, and because the fixed frame 2 is stationary, the coil assembly 32 is also stationary, avoiding problems such as wire entanglement caused by the movement of the coil assembly 32. In some embodiments, the magnetic moving assembly 31 is connected to the fixed frame 2, and the coil assembly 32 is connected to the moving frame 1.
[0039] In some embodiments, please refer to Figure 4 The permanent magnet 311 is a hollow cylinder extending in the horizontal direction. The permanent magnet 311 includes a third end face 3112 and a fourth end face 3113 opposite to each other in the horizontal direction. The third end face 3112 is close to the coil assembly 32, and the fourth end face is far away from the coil assembly 32. The magnetic dynamic assembly 31 also includes a first metal gasket 312 in a circular shape. The first metal gasket 312 is connected to the third end face 3112. The axis of the first metal gasket 312 coincides with the axis of the permanent magnet 311. The wire coil 321 is inserted through the first metal gasket 312. The first metal gasket 312 makes the magnetic field lines of the permanent magnet 311 more concentrated, concentrated at the first metal gasket 312, and increases the magnetic force between the permanent magnet 311 and the wire coil 321.
[0040] In some embodiments, please continue to refer to Figure 4The first metal gasket 312 includes a circular first hole 3121, and the wire coil 321 is inserted into the first hole 3121. The diameter of the first hole 3121 is smaller than the diameter of the channel hole 3111. The diameter of the first hole 3121 is smaller than the diameter of the channel hole 3111, so that the magnetic field lines of the permanent magnet 311 are further concentrated, thereby increasing the magnetic force between the permanent magnet 311 and the wire coil 321.
[0041] In some embodiments, the permanent magnet 311 is a hollow cylinder extending in the horizontal direction, the permanent magnet 311 includes a third end face 3112 and a fourth end face 3113 opposite to each other in the horizontal direction, the magnetic moving assembly 31 also includes a second metal gasket 313, the second metal gasket 313 includes a main body 3121, the main body 3121 is a cylinder extending in the horizontal direction, the second metal gasket 313 includes a fifth end face 3132 and a sixth end face 3133 opposite to each other in the horizontal direction, the fifth end face 3132 is connected to the fourth end face 3113, the sixth end face 3133 is connected to the moving frame 1, and the axis of the second metal gasket 313 coincides with the axis of the permanent magnet 311. By arranging the second metal sheet at the end of the permanent magnet 311 away from the wire coil 321, the magnetic field lines of the permanent magnet 311 are more concentrated, and the magnetic force between the permanent magnet 311 and the wire coil 321 is increased.
[0042] In some embodiments, please continue to refer to Figure 4 The second metal gasket 313 also includes an extension portion 3134, which extends from the fifth end surface 3132 toward the permanent magnet 311. The extension portion 3134 is a cylinder extending in the horizontal direction, and the axis of the extension portion 3134 coincides with the axis of the permanent magnet 311. The wire coil 321 includes a first inner cavity 3213 opening toward the permanent magnet 311, and the first inner cavity 3213 is used to accommodate the extension portion 3134. Providing the extension portion 3134 on the second metal sheet is conducive to further concentrating the magnetic field lines of the permanent magnet 311 and increasing the magnetic force between the permanent magnet 311 and the wire coil 321. At the same time, providing the first inner cavity 3213 for accommodating the extension portion 3134 on the wire coil 321 is conducive to increasing the stroke of the extension portion 3134, that is, increasing the stroke of the permanent magnet 311.
[0043] In some embodiments, the extension portion 3134 is partially located in the first inner cavity 3213 of the wire coil 321. Since the magnetic field lines at the extension portion 3134 are more evenly distributed, the wire coil 321 is in a more uniform magnetic field, which is conducive to more stable operation of the moving frame 1.
[0044] In some embodiments, the end of the extension portion 3134 away from the main body 3121 is disposed between the first end 3211 and the second end 3212 of the wire coil 321. The extension portion 3134 is located in the wire coil 321, which is conducive to making the magnetic field generated by the permanent magnet 311 and the magnetic field generated by the wire coil 321 more uniform.
[0045] In some embodiments, please refer to Figure 5 and Figure 6 , Figure 6 For the sake of clarity, the wire coil 321 disposed in the slot 3223 is omitted. The coil assembly 32 also includes a receiving member 322, which is disposed in the first inner cavity 3213. The receiving member 322 is a cylinder extending in the horizontal direction. The receiving member 322 is provided with a second inner cavity 3221 opening toward the permanent magnet 311. The second inner cavity 3221 is used to accommodate at least part of the extension portion 3134. The outer circumferential surface 3222 of the receiving member 322 is recessed inwardly in the circumferential direction to form a slot 3223, and the wire coil 321 is disposed in the slot 3223. The wire coil 321 is fixed by providing the slot 3223 to prevent the wire coil 321 from moving along the axial direction of the wire coil 321.
[0046] In some embodiments, the height of the wire coil 321 in the radial direction does not exceed the outer circumference 3222 of the receiving member 322. By limiting the wire coil 321 from exceeding the outer circumference 3222 of the receiving member 322, the wire coil 321 is prevented from filling the movement gap between the receiving member 322 and the channel hole 3111, thereby preventing jamming.
[0047] In some embodiments, the end of the extension portion is connected to the connection mechanism 4 by hinge connection, and the end of the extension portion 3134 is connected to the connection structure by hinge connection.
[0048] In some embodiments, the rhythmic furniture further includes a connecting mechanism 4, which is used to connect the moving frame 1 and the fixed frame 2, so that the moving frame 1 generates a movement with the same relative movement speed relative to the fixed frame 2 based on the relative movement of the magnetic moving component 31 and the coil component 32.
[0049] In some embodiments, the fixed frame 2 also includes an extension portion extending upward, and the end of the extension portion is connected to the connecting mechanism 4. The movable frame 1 also includes an extension portion 3134, and the end of the extension portion 3134 is connected to the connecting mechanism 4. In the vertical direction, the end of the extension portion is higher than the end of the extension portion 3134, so that the movable frame 1 is suspended on the fixed frame 2.
