Description

[Technical Field]

[0001] The present invention relates to a magnetic levitation device. [Background technology]

[0002] Conventional magnetic levitation devices typically include a levitator and a levitating body. The levitator generally takes the form of a base or a suspension, and the levitating body can take various suitable forms, such as a globe, a Bluetooth speaker, a moon phase lamp, a flower pot, or a decorative ornament. The levitating body can be raised and lowered from the levitator manually or automatically. Patent Documents 1, 2, 3, 4, 5, and 6 all disclose providing a lifting mechanism within the levitator base to achieve automatic lifting and lowering of the levitating body. However, providing a lifting mechanism within the levitator base inevitably imposes dual constraints of space and cost. [Prior art documents] [Patent documents]

[0004] SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic levitation device that can realize automatic levitation or landing of a levitation body in a simple manner. [Means for solving the problem]

[0005] According to a first aspect of the present invention, there is provided a levitation body for a magnetic levitation device, the levitation body including a housing and a magnetic member, the housing and the magnetic member being arranged to be movable relative to each other, and the relative movement of the magnetic member and the housing being guided by a linear guide mechanism arranged on the levitation body.

[0006] According to the float of the present invention, the linear guide mechanism can be formed in the housing and / or the magnetic member.

[0007] In accordance with the levitator of the present invention, the housing is preferably a closed or nearly closed housing, more preferably a sphere, such as a transparent or non-transparent sphere, or a box.

[0008] According to the levitation body of the present invention, it is preferable that the magnetic member always moves within the housing. Of course, the magnetic member may protrude from the housing, for example, protruding upward and / or downward from the housing. If the magnetic member protrudes downward from the housing, it can be used, for example, as a hidden display frame, and the levitation body can be used as a storage box in this case.

[0009] The levitation body of the present invention may further include a motor that provides a driving force for the relative movement between the magnetic member and the housing, and in this case, generally, may further include a transmission mechanism that transmits the driving force of the motor to the magnetic member or the housing.

[0010] The levitator of the present invention may further include a stopper mechanism for restricting the upward / downward movement limits of the relative movement between the magnetic member and the housing.

[0011] According to the floatation body of the present invention, the linear guide mechanism of the housing is preferably a straight cylinder, and the magnetic member is located inside the straight cylinder.

[0012] In the case of guidance by a straight cylinder, it is more preferable that the magnetic member and the straight cylinder form a piston-type vacuum mechanism. Alternatively, the straight cylinder may be formed with a stopper member (upper or lower), and a compression spring is positioned between the stopper member and the magnetic member. Therefore, in this case, it is possible to achieve automatic lifting of the levitation body without using a motor.

[0013] Of course, other linear guide mechanisms, such as screws, may be used to engage nuts on the magnetic member, or vice versa.

[0014] According to the levitation body of the present invention, the housing may further be provided with a positioning mark for indicating the linear movement direction of the linear movement mechanism or the corresponding position of the magnetic member.

[0015] The levitation body may also be provided with electrical devices such as audio and light emitting devices, and wireless or wired charging devices.

[0016] According to a second aspect of the present invention, there is further provided a magnetic levitation device, which includes a levitator and the levitation body, and the levitation body can be levitated by the levitator.

[0017] According to the magnetic levitation device of the present invention, the levitator can be in the form of a pedestal, and the levitation body can levitate above the pedestal. In this case, it is preferable that a positioning center point is provided on the upper surface of the pedestal, and when the pedestal is placed horizontally, the magnetic member of the levitation body can levitate directly above the positioning center point.

[0018] According to the magnetic levitation device of the present invention, the levitator can take the form of a suspension, and the levitating body can levitate below the highest point of the suspension.

[0019] According to the magnetic levitation device of the present invention, the levitator base can also be designed as a calendar base. The base is provided with at least one indicator chute and an indicator bead movably positioned on the at least one indicator chute. The at least one indicator chute includes two annular indicator chutes spaced apart from each other in the radial direction, one of which has a date mark and the other of which has a week or month mark, each of which corresponds to a corresponding indicator bead. The levitator is also a spherical moon phase lamp, half of which can be lit and the other half of which is kept relatively dark.

[0020] According to a third aspect of the present invention, there is further provided a method for raising and lowering a levitation body using the magnetic levitation device, the method comprising: disposing the levitator base substantially horizontally; Placing the levitation body on a levitator base, and aligning the magnetic member of the levitation body with the positioning center point of the levitation base along the linear guide mechanism direction; moving the magnetic member along the linear guide mechanism direction to a set levitation height so that the magnetic member is stably levitated relative to the levitator base; and moving the levitator housing upward relative to the magnetic member and away from the levitator base until the desired height is reached.

[0021] The method according to the present invention may further include moving the levitator housing downward relative to the magnetic member until it is at a desired height or until it contacts the levitator base.

[0022] According to the method of the present invention, the relative movement between the housing of the levitation body and the magnetic member may be performed by an electric drive mechanism, for example, a motor and a transmission mechanism may be provided in the levitation body to control the relative movement between them.

[0023] According to the method of the present invention, the relative movement between the housing of the levitator and the magnetic member may be performed by an elastic automatic return mechanism or a manual return mechanism. This method omits the use of a motor, thereby simplifying the device configuration and further reducing costs.

[0024] According to the method of the present invention, the elastic return mechanism is a piston type vacuum mechanism and / or a spring mechanism.

[0025] The method of the present invention may further include providing positioning and engaging mechanisms on the levitator base and the levitator body, respectively, so that when the levitator body is placed on the levitator base, the positioning and engaging mechanisms ensure that the magnetic member of the levitator body is aligned with the positioning center point of the levitator base along the linear guide mechanism direction. [Effects of the Invention]

[0026] The present invention provides a linearly or vertically movable magnetic member within the levitator, eliminating the need for a lifting mechanism within the levitator base, and easily achieving automatic lifting and landing of the levitator relative to the levitator base, which not only creates a powerful visual effect and a sense of mystery, but also allows the levitator base to maintain the conventional compact or miniaturized flat structure.

[0028] The present invention will be further described below with reference to examples and drawings. The examples and drawings are provided to help those skilled in the art better understand the present invention and are not intended to limit the scope of the present invention. For example, the levitation body described in the following examples is used in a pedestal-type magnetic repulsion type levitation device, but can also be used in a suspension-type levitation device or a magnetic attraction type magnetic levitation device.

[0029] The magnetic levitation device of the present invention generally includes a levitator (also referred to as a "magnetic levitation support mechanism") and a levitating body (also referred to as a "levitation support body"), which can stably levitate the levitating body in the air by the levitator. The specific structure and operating principle of such a magnetic levitation device are well known in the art and will not be described in detail here to save space. For example, see Chinese Patent No. 100544183, Chinese Patent No. 105790641, Chinese Patent Application Publication No. 112086312, and U.S. Patent No. 7,505,243, the entire contents of which are incorporated herein by reference. The levitator typically takes the form of a base or suspension on which a magnetic assembly (e.g., a permanent magnetic ring-core magnet), a sensor (e.g., a Hall sensor), and control elements such as an electromagnetic coil are mounted. The levitating body also includes a magnetic member such as a permanent magnetic column magnet.

[0030] FIG. 1 shows a schematic cross-sectional structure of a levitation body LO according to a first embodiment of the present invention. The levitation body LO includes a spherical housing 10. Optionally, a positioning recess 11 is provided at the bottom of the housing. A vertical guide tube 12 is fixedly provided inside the housing 10. The central symmetry axis of the guide tube 12 is aligned vertically with that of the positioning recess 11. Optionally, ventilation holes 13 and 14 are provided at the top and bottom of the guide tube 12.

[0031] The cylindrical magnetic member 20 is provided inside the guide tube 12 and is in close engagement with the inner wall of the guide tube 12, optionally via a seal ring 21 located on the outer circumferential wall of the magnetic member 20. Optionally, a compression spring 15 is provided between the magnetic member 20 and the top cover 15 of the guide tube 12.

[0032] 2 is a cross-sectional view showing a schematic diagram of a levitation body LO placed on a base LB as a levitator. As shown in the figure, a positioning protrusion P is optionally provided on the upper surface of the base LB, which is inserted into a positioning recess 11 of the levitation body LO to perform initial positioning.

[0033] As shown in FIG. 2, when the levitator LO is placed on the base LB, a magnetic assembly, e.g., a ring magnet (not shown), within the base LB generates a repulsive force against the magnetic member 20 within the levitator LO. This causes the magnetic member 20 to automatically rise from the bottom of the guide tube 12 shown in FIG. 1 to a preset levitation height (depending on the specific settings of the device itself) as shown in FIG. 2, and stably levitate at this equilibrium position. At this time, if the lower vent 14 is omitted, and the top cover 15 and spring 15 of the guide tube 12 are also omitted, the magnetic member 20 with the seal ring 21 acts as a piston to draw a vacuum, creating a nearly vacuum state in the space below the magnetic member 20 within the guide tube 12. Next, as shown in FIG. 3, the housing 10 of the levitator LO automatically rises due to the vacuum effect until the bottom of the guide tube 12 nearly contacts the magnetic member 20. Furthermore, due to the vacuum damping effect, the levitator LO slowly rises from the base LB, creating a visual effect.

[0034] 2, the top cover 15, the spring 16, the upper and lower vent holes 13, 14 are held together, and optionally the seal ring 21 is also held. At this time, due to the pressure applied to the top cover 15 by the spring 16, the housing 10 of the levitation body LO still automatically rises to the position shown in FIG.

[0035] Of course, those skilled in the art will recognize that the relative return mechanism between the housing 10 and the magnetic member 20 may use a combination of the piston vacuum action and spring pressure action. Other appropriate elastic return mechanisms may also be used. The return mechanism may also be operated manually without using an automatic elastic return mechanism. For example, elastic engagement mechanisms may be provided on the guide tube, which is a linear guide mechanism, and the magnetic member 20, respectively, and engagement and disengagement between the two may be achieved by applying an external force (for example, by pressing down on the housing 10). Other appropriate linear guide mechanisms other than the guide tube, such as a guide rod, may also be used.

[0036] FIG. 4 shows a schematic cross-sectional structure of a levitation body LO according to a second embodiment of the present invention. The levitation body LO includes a spherical housing 10. Optionally, a positioning recess 11 is provided at the bottom of the housing. A cylindrical holder 17 is fixed inside the housing 10, and a motor 18 having a hollow screw rotation shaft is fixed to the holder 17. The motor 18 is fixed to the holder 17 via the housing. The hollow screw rotation shaft is arranged vertically and is aligned vertically with the positioning recess 11.

[0037] The cylindrical magnetic member 20' is provided inside the holder 17, and a screw post 22 is fixedly attached to the cylindrical magnetic member 20'. The screw post 22 projects upward from the holder 17 and passes through the hollow screw rotary shaft of the motor 18 so as to be threadedly engaged therewith.

[0038] 5 is a cross-sectional view showing a schematic diagram of a levitation body LO placed on a base LB as a levitator. As shown in the figure, a positioning protrusion P is optionally provided on the upper surface of the base LB, which is inserted into a positioning recess 11 of the levitation body LO to perform initial positioning.

[0039] As shown in FIG. 6, when the levitator LO is placed on the base LB, the magnetic member 20' is positioned at a set levitation height by initial setting or by driving the motor 18. At this time, the magnetic member 20' stably levitates at this equilibrium position due to the repulsive force of the magnetic assembly, e.g., a ring magnet (not shown), in the base LB relative to the magnetic member 20' in the levitator LO. Next, as shown in FIG. 6, for example, by rotating the hollow screw shaft of the motor 18 using a remote switch (not shown) or remote control provided on the base LB, the motor 18 drives the housing 10 of the levitator LO to rotate upward along the screw post 22 on the magnetic member 20' until the bottom of the housing 10 approaches the magnetic member 20' and separates from the base LB. Then, by controlling the reverse rotation of the motor 18, the housing 10 can be lowered to a desired height or to the initial landing position shown in FIG. 5. Furthermore, the rotary up-and-down movement of the housing 10 allows the levitator LO to rotate horizontally as it rises from the base, creating a visual effect.

[0040] FIG. 7 is a schematic diagram of a modified example of a levitation body according to a second embodiment of the present invention, in which the transmission device is different from that of the embodiment shown in FIG. 4, but the rest is the same.

[0041] As shown in FIG. 7, the motor 18' fixed to the holder 17 is a normal motor and has a rotating shaft 19' that projects vertically downward. The housing of the motor 18' is still fixed to the holder 17, but is offset parallel to the threaded post 22 of the magnetic member 20'. The rotating shaft 19' is fixed to a gear 101, which meshes with a transmission gear 102, and the transmission gear 102 is threadedly engaged with the threaded post 22 of the magnetic member 20' that passes through it. In this case, the motor 18' can also be driven to automatically raise and lower the housing 10 of the levitation body LO, as shown in FIG. 8.

[0042] 9 is a schematic diagram showing a modified example of a levitation body according to a second embodiment of the present invention, in which the transmission device is different from that of the embodiments shown in FIGS. 4 and 7, but the rest is the same.

[0043] As shown in FIG. 9, an outer cylinder 103 is fitted into the cylindrical holder 17 and is slidable up and down. The outer cylinder 103 is further provided with guide ribs 104 that allow the outer cylinder 103 to move up and down without rotating relative to the cylindrical holder 17. The motor 18' fixed to the outer cylinder 103 is also a conventional motor and has a rotating shaft 19' that protrudes vertically downward. The rotating shaft 19' is fixed vertically aligned with a screw post 22 of a magnetic member 20'. A nut 105 is fixed to the top of the cylindrical holder 17 and is threadedly engaged with the screw post 22 of the magnetic member 20' that passes through it. In this case, the motor 18' can also be driven to automatically raise and lower the housing 10 of the levitation body LO, as shown in FIG. 10.

[0044] FIG. 11 shows a disk-shaped base LB. The illustrated disk-shaped base LB has a housing 30 with a central circular receiving recess 33 formed therein. Two concentric annular groove-shaped first and second support chutes 31 and 32 are arranged on the upper surface of the housing 30, spaced apart from each other in the radial direction, with the receiving recess 33 at the center. A first support bead 311 is movably positioned at one of a plurality of set positions 310 within the first support chute 311, and a second support bead 321 is movably positioned at one of a plurality of set positions 320 within the second support chute 32. The illustrated first support bead 311 and second support bead 321 may be iron balls. The housing 30, which will be described later, also includes annular magnets 35 positioned below the first support chute 31 and second support chute 32, allowing the corresponding iron balls to be quickly and easily positioned at the desired set positions of the support chutes when moved or shifted along the support chutes.

[0045] In the calendar base shown in FIG. 11, the height of the disk body of the illustrated base LB gradually decreases radially outward, except in the region where the receiving recess and the annular groove are located.

[0046] The embodiment shown in Fig. 12 is similar to that shown in Fig. 2, except that it uses the calendar base LB shown in Fig. 11. As shown in Fig. 12, a magnetic levitation system including a control circuit board 34, annular magnet 35, electromagnetic coil 26, iron core 37, etc. is also provided within housing 30 of base LB. The levitating body LO can also rise from the position shown in Fig. 12 to the position shown in Fig. 13, as described above.

[0047] 14 is a perspective view of a levitator LO floating above the calendar base LB shown in FIG. 11, where the levitator LO takes the form of a spherical moon phase lamp. Such a spherical moon phase lamp may have regions of inconsistent brightness on its spherical outer surface, for example, one half dark and one half lit, as shown. Such a spherical moon phase lamp may have a spherical housing that is half transparent and the other half translucent or semi-transparent, and a light source located inside the spherical housing.

[0048] Alternatively, such a spherical moon phase lamp may have a 3D printed spherical housing and light source, with the interior of the spherical moon phase lamp divided into two sections by a light shield, with the light source located in one of the sections. Furthermore, the two sections of the spherical moon phase lamp separated by the light shield may each have a light source that can be independently controlled to achieve half- or full-on states as desired.

[0049] The embodiment shown in FIG. 15 is similar to that shown in FIG. 14, except that it employs a calendar base with a generally flat shape.

[0050] Figure 16 is a plan view of the calendar base shown in Figure 15, where the arc-shaped indicator chute 31 is provided with a corresponding day of the week indicator, and the arc-shaped indicator chute 32 is provided with a corresponding date indicator. Figure 17 is a front view of the calendar base LB shown in Figure 16, which also includes a charging port 38. In the embodiment shown in Figure 17, although not specifically shown, a wireless charging transmitter is also provided within the base LB, and a wireless charging receiver corresponding to the wireless charging transmitter on the base is also provided within the spherical moon phase lamp to wirelessly power or charge the spherical moon phase lamp. This magnetic levitation calendar device can realistically simulate the changes in the moon's phases and clearly indicate the calendar.

[0051] Those skilled in the art will understand that when a motor is used, other variations of the transmission device are possible. The linear guide mechanism is not limited to the above-mentioned screw or nut type, and for example, a cylinder used in a pneumatic drive system may be used as the linear guide mechanism.

[0052] Although not specifically shown, the levitation body may also be equipped with electrical devices such as audio and lighting. The levitation body may also be equipped with a wireless or wired charging device to supply power to the power-consuming devices within the levitation body. For example, when wireless power supply is used, a wireless power supply receiving coil is installed within the levitation body and combined with a wireless power supply transmitting coil installed within the base.

[0053] Furthermore, although not specifically shown, the levitation body of the present invention may include a stopper mechanism for restricting the upward / downward movement limits of the relative movement between the magnetic member and the housing. For example, a stroke switch may be set in the motor to automatically stop operation at a predetermined position.

[0054] Those skilled in the art will understand that the illustrated embodiments are used solely to better understand the present invention and are not intended to be limiting. For example, the directional terms described above are used only for the drawings. Furthermore, the housing 10 of the levitation body LO of the present invention is not limited to such a closed spherical housing structure, but may have other shapes, such as a rectangular box, or any other suitable closed, semi-closed, or open shape. The housing 10 may be made of a transparent, opaque, or non-transparent material. Furthermore, the magnetic member 20 or 20' of the present invention is not limited to being always disposed within the housing 10, but may be exposed above or below the housing 10 during movement.
