Description

Technical Field

[0001] The present application relates to the technical field of household products, and in particular to a magnetic drive base device and rhythmic furniture. Background Art

[0002] With the continuous progress of society, people's quality of life is constantly improving. Rhythmic furniture is a daily necessity commonly used by people in their leisure time. The reciprocating motion of rhythmic furniture can improve the quality of life.

[0003] In related art, high-quality rhythmic furniture uses a magnetic drive base as a power source to drive the furniture's reciprocating motion. This system features vibration-free, low-noise, and smooth movement. The principle is to energize a coil unit to generate a magnetic field in which the magnetic poles switch at a predetermined frequency, thereby driving the magnetic unit in a predetermined direction and causing the rhythmic furniture's body to reciprocate. However, due to the presence of resistance and wires, current passing through the coil unit generates a certain amount of heat. Excessive current, or a faster switching frequency, increases the heat generation, leading to overheating of the coil unit and affecting the performance and lifespan of the magnetic drive base. Utility Model Content

[0004] The embodiments of the present application provide a magnetic drive base device and rhythmic furniture to at least solve the problems of limited performance and short life of the existing magnetic drive base device due to overheating of the magnetic drive device.

[0005] A first embodiment of the present application provides a magnetic drive base device, comprising:

[0006] Fixed frame;

[0007] A rhythm frame, the rhythm frame being configured to be capable of reciprocating motion relative to the fixed frame;

[0008] The magnetic drive mechanism includes a coil assembly fixed relative to the fixed frame and a magnetic dynamic assembly fixed relative to the rhythm frame, the coil assembly includes a coil support with a through-hole and a coil winding wrapped around the outer surface of the coil support, and the magnetic dynamic assembly is inserted into the through-hole;

[0009] A support substrate is connected to the fixing frame, wherein the support substrate has a first surface and a second surface opposite to each other, the coil support is connected to and supported by one of the first surface and the second surface, and areas of the first surface and the second surface that are not used for connecting the coil support are exposed.

[0010] The magnetic drive base device according to the embodiment of the present application has at least the following beneficial effects:

[0011] By providing a support substrate that is in contact with the coil bracket, the heat generated by the coil winding can be transferred to the support substrate through the coil bracket. At the same time, the exposed support substrate design is conducive to quickly transferring heat to the air, so as to quickly reduce the temperature of the coil winding, thereby improving the performance and life of the magnetic drive mechanism to a certain extent.

[0012] In one possible embodiment, the support base is arranged horizontally within the horizontal projection of the fixed frame, and the coil holder is disposed on the top surface of the support base. Horizontally arranging the support base reduces the vertical distance between the support bases, thereby lowering the height of the support bases. This lowers the center of gravity of the magnetic drive mechanism and improves its stability during operation.

[0013] In one possible embodiment, the support substrate extends to an edge of the mounting frame along at least one of the length and width of the mounting frame. Extending to the edge of the mounting frame provides a larger support substrate area, which facilitates faster heat dissipation from the coil windings and promotes stable operation of the magnetic drive mechanism.

[0014] In a possible embodiment, the support substrate is provided with a sunken portion along its length, which is helpful in increasing the surface area of ​​the support substrate, that is, improving the heat dissipation capacity of the support substrate.

[0015] In one possible embodiment, a thermally conductive layer is placed between the side of the coil winding facing the top surface and the top surface. Providing a thermally conductive layer between the coil winding and the support substrate increases the heat transfer pathways within the coil winding. Heat generated by the coil winding is transferred to the support substrate via the coil support and then to the support substrate via the thermally conductive layer, thereby improving heat transfer efficiency and rapidly reducing the temperature of the coil winding.

[0016] In a possible implementation, the heat-conducting layer includes a heat-conducting gel layer, a heat-conducting silicone grease layer, or a heat-conducting adhesive layer.

[0017] In one possible embodiment, the heat conductive layer forms an arc-shaped covering portion along the circumference of the outer surface of the coil support. By providing the arc-shaped covering portion on the heat conductive layer, the heat conductive layer fits the coil support more closely, making the heat transfer generated by the coil winding more stable.

[0018] In a possible embodiment, the support substrate is formed by cutting a stainless steel plate. The support substrate made of a stainless steel plate has high strength and good heat dissipation effect.

[0019] In one possible embodiment, a cooling fan is further included, configured to force airflow across the surface of the coil winding. When in operation, the cooling fan forces airflow across the outer surface of the coil winding, thereby generating forced convection on the outer surface of the coil winding. This effectively removes heat accumulated on the outer surface of the coil winding, maintaining the temperature of the coil winding within a reasonable range, and thus preventing problems such as reduced performance and shortened lifespan of the coil winding due to overheating.

[0020] The second embodiment of the present application provides a rhythmic furniture, comprising the magnetic drive base device and a furniture body as described in the first embodiment above, wherein the furniture body is mounted on the rhythmic frame.

[0021] The rhythmic furniture according to the embodiments of the present application has at least the following beneficial effects:

[0022] Since the magnetic drive base device of the first embodiment is provided, the rhythmic furniture of this embodiment can also improve the heat dissipation capacity of the magnetic drive mechanism to a certain extent, thereby increasing the life of the magnetic drive mechanism.

[0044] The following combination Figures 1 to 4 This application introduces a magnetic drive base device according to one embodiment. This magnetic drive base device is suitable for various types of rhythmic furniture. The rhythmic furniture includes a furniture body that supports the user and a magnetic drive base device disposed at the bottom of the furniture body. It should be noted that in some embodiments of this application, the rhythmic furniture is a rhythmic chair, and the magnetic drive base device is located at the bottom of the rhythmic chair. Of course, in other embodiments, the magnetic drive base device can also be applied to rhythmic sofas, rhythmic beds, etc.

[0045] Figure 1 This is a structural diagram of a magnetic drive base device according to an embodiment of the present application. Figure 1As shown, it includes a fixed frame 100, a rhythm frame 200, a magnetic drive mechanism 300 and a support base plate 400. The rhythm frame 200 is configured to be able to reciprocate relative to the fixed frame 100, wherein the magnetic drive mechanism 300 includes a coil assembly 310 fixed relative to the fixed frame 100 and a magnetic dynamic assembly 320 fixed relative to the rhythm frame 200. The coil assembly 310 includes a coil support 311 with a through channel hole and a coil winding 312 wrapped around the outer surface of the coil support 311. The magnetic dynamic assembly 320 is inserted into the channel hole. The support base plate 400 is connected to the fixed frame 100. The support base plate 400 has a first surface 410 and a second surface 420 relative to each other. The coil support 311 is connected to and supports one of the first surface 410 and the second surface 420. The areas of the first surface 410 and the second surface 420 that are not used for connecting the coil support 311 are exposed. The magnetic drive mechanism 300 adopts an electromagnetic drive method as the driving power. The coil winding 312 generates obvious heat during the operation of the magnetic drive mechanism 300. By setting a support substrate 400 that is in contact with the coil bracket 311, the heat generated by the coil winding 312 can be transferred to the support substrate 400 through the coil bracket 311. At the same time, the exposed support substrate 400 design is conducive to quickly transferring heat to the air, so as to quickly reduce the temperature of the coil winding 312, so as to improve the performance and life of the magnetic drive mechanism to a certain extent.

[0046] It will be understood that the magnetic drive mechanism 300 is used to drive the rhythm frame 200 to reciprocate relative to the fixed frame 100. Specifically, the magnetic drive mechanism 300 includes a coil assembly 310 and a magnetic dynamic assembly 320. The coil assembly 310 is connected to the fixed frame 100, thereby the two are relatively fixed, and the magnetic dynamic assembly 320 is connected to the rhythm frame 200, thereby the two are also relatively fixed. When the magnetic drive mechanism 300 is in operation, it energizes the coil assembly 310 to generate a magnetic field in which the magnetic poles switch at a predetermined frequency, thereby driving the magnetic dynamic assembly 320 to reciprocate in a preset direction. As a result, the magnetic dynamic assembly 320 can move relative to the coil assembly 310, thereby driving the rhythm frame 200 to move relative to the fixed frame 100.

[0047] It is understood that the coil support 311 has a cylindrical body portion that defines a through-hole extending along its axial direction. It is understood that, on the one hand, the outer wall of the body portion serves as a framework for winding the coil winding 312, and on the other hand, the through-hole is used to accommodate the magnetic assembly 320, which includes a drive shaft and a magnet mounted on the drive shaft. Furthermore, a certain gap exists between the outer wall of the magnetic assembly 320 and the inner wall of the through-hole, allowing the magnetic assembly 320 to move freely within the through-hole without being fixed or restricted. As a result, when the magnetic drive mechanism 300 is operating, the magnetic assembly 320 can move smoothly within the through-hole without contact or friction with the coil support 311. The movement of the magnetic assembly 320 is smooth, resulting in vibration-free and noise-free operation of the magnetic drive mechanism 300. The coil support 311 has a support frame that supports the body portion, and the support frame is connected to the support base plate 400.

[0048] It can be understood that the exposed surfaces refer to the first surface 410 and the second surface 420 that are not in direct contact with the coil and are in direct contact with the air.

[0049] It is understood that the coil winding 312 can be formed by winding a wire, for example, by wrapping a plurality of turns of pure copper enameled wire around the coil support 311. The specific winding parameters can be determined according to actual needs. It is also understood that the coil winding 312 formed by winding the wire has a cylindrical outer circumference and annular end surfaces located on both sides of the axial direction of the coil winding 312. The outer circumference and the two end surfaces together constitute the outer surface of the coil winding 312. It is understood that the outer surface of the coil winding 312 is formed by the surface accumulation of the intertwined wires and is not a continuously extending smooth surface.

[0050] In some embodiments, the support base plate 400 is arranged horizontally within the horizontal projection range of the fixing frame 100, and the coil bracket 311 is disposed on the top surface 430 of the support base plate 400. Arranging the support base plate 400 horizontally can reduce the vertical distance of the support base plate 400, thereby reducing the height of the support base plate 400, thereby lowering the center of gravity of the magnetic drive mechanism 300 and improving the stability of the magnetic drive mechanism 300 during operation.

[0051] In some embodiments, the support substrate 400 is a thin plate, and the thickness direction of the support substrate 400 is the vertical direction. In the vertical direction, the support substrate 400 includes a top surface 430 and a bottom surface 440. The top surface 430 is located above the bottom surface 440, so the magnetic drive mechanism 300 is located above the support substrate 400.

[0052] In some embodiments, the first surface 410 is a top surface 430 , the first surface 410 is supported and connected to the coil support 311 , and the second surface 420 is a bottom surface 440 .

[0053] In some embodiments, the support substrate 400 extends to the edge of the fixing frame 100 along at least one of the length and width directions of the fixing frame 100. The support substrate 400 extending to the edge of the fixing frame 100 has a larger area, which is more conducive to faster heat dissipation of the coil winding 312 and facilitates stable operation of the magnetic drive mechanism 300.

[0054] In some embodiments, the support substrate 400 is provided with a sinking portion (not shown in the figure) along its length direction. By providing the sinking portion, it is beneficial to increase the surface area of ​​the support substrate 400, that is, to improve the heat dissipation capacity of the support substrate 400. It is understandable that the sinking portion can be provided on the top surface 430 of the support substrate 400, or it can be provided on the bottom surface 440 of the support substrate 400. Taking the sinking portion provided on the top surface 430 of the support substrate 400 as an example, the sinking portion is formed by the top surface 430 of the support substrate 400 being recessed toward the bottom surface 440. The shape of the sinking portion is not limited and can be rectangular, elliptical, etc. The sinking portion extends along the length direction of the support substrate 400. Compared with extending along the width direction, the sinking portion forms a larger area on the support substrate 400, so as to increase the heat dissipation surface area of ​​the support substrate 400 and improve the heat dissipation capacity.

[0055] In some embodiments, as Figure 3 As shown, Figure 3 For illustration purposes, one side of the coil support is hidden to show the heat-conducting layer 500. A heat-conducting layer 500 is filled between the side of the coil winding 312 facing the top surface 430 and the top surface 430. By providing the heat-conducting layer 500 between the coil winding 312 and the support substrate 400, the heat transfer path of the coil winding 312 can be increased. The heat generated by the coil winding 312 is transferred to the support substrate 400 through the coil support 311 and to the support substrate 400 through the heat-conducting layer 500, thereby improving the heat transfer efficiency and facilitating the rapid reduction of the temperature of the coil winding 312. In some embodiments, the heat-conducting layer 500 can also cover the surface of the entire coil winding 312, so that the heat generated by the entire coil winding 312 can be quickly transferred to quickly reduce the temperature.

[0056] In some embodiments, the thermally conductive layer 500 includes a thermally conductive gel layer, a thermally conductive silicone grease layer, or a thermally conductive paste layer. The thermally conductive gel layer, thermally conductive silicone grease layer, or thermally conductive paste layer has good thermal conductivity and helps quickly transfer heat generated by the coil winding 312 to the support substrate 400, thereby achieving rapid cooling.

[0057] In some embodiments, see Figure 4The heat conductive layer 500 forms an arc-shaped covering portion 510 along the circumferential direction of the outer peripheral surface of the coil support 311. By providing the arc-shaped covering portion 510 on the heat conductive layer 500, the heat conductive layer 500 fits more closely to the coil support 311, making the heat transfer generated by the coil winding 312 more stable.

[0058] In some embodiments, the support substrate 400 is formed by cutting a stainless steel plate. The support substrate 400 made of a stainless steel plate has high strength and good heat dissipation effect.

[0059] It is understandable that the stainless steel plate is not easily deformed when heated, and the stainless steel will not affect the magnetic field generated by the coil winding 312 , thereby reducing interference with the rhythm rack 200 .

[0060] In some embodiments, the magnetic drive base device further includes a cooling fan 600, which is configured to propel airflow across the surface of the coil winding 312. When in operation, the cooling fan 600 propels airflow by forcing airflow across the outer surface of the coil winding 312, thereby generating forced convection on the outer surface of the coil winding 312. This effectively removes heat accumulated on the outer surface of the coil winding 312, maintaining the temperature of the coil winding 312 within a reasonable range and avoiding issues such as reduced performance and shortened lifespan of the coil winding 312 due to overheating. It is understood that the cooling fan 600 can employ a variety of different fan types, such as axial fans, centrifugal fans, and mixed flow fans. Because axial fans are compact and easy to install, and they propel air in the same axial direction, facilitating control of airflow direction, in this embodiment, the cooling fan 600 is preferably an axial fan.

[0061] In some embodiments, the number of the heat dissipation fans 600 is two and they are arranged opposite each other, the coil winding 312 is arranged between the two heat dissipation fans, and the two heat dissipation fans 600 are arranged symmetrically.

[0062] The embodiment of the present application further provides a rhythmic furniture, comprising a furniture body and a magnetic drive base according to any of the aforementioned embodiments, wherein the furniture body is mounted on a rhythmic frame 200 of the magnetic drive base.
