Levitation display device {Levitation display device}

One embodiment of the present invention relates to a levitation display device.

In general, levitation means floating in the air without a physical point of contact at a stable position against gravity.

These levitation display devices are those using air pressure or magnetic force, and until recently, levitation devices mainly by air pressure have been researched and developed.

On the other hand, recently, the levitation display device for levitation object to a predetermined position in a non-contact manner through the attraction or repulsive force generated by the magnet has been researched and developed. For example, a device for supporting a spinning magnet top or levitation of a globe or the like is known.

The levitation principle of the magnet top is that when the magnet top is rotated, there is a force that the torque is created and does not sweep. This principle is used to float on a plate magnet having the same polarity, that is, repulsive force.

In other words, the electromagnet is installed on the upper end of the device, the permanent magnet is installed on the globe, and the lifting height is adjusted using a sensor installed at the center of the electromagnet. Since the globe always has a force to fall down due to gravity, there is no horizontal force but only a vertical force, so it is a relatively simple device if only a vertical force is controlled using an electronic circuit.

However, such a conventional flotation device is not suitable as a device for levitation and display of various goods. That is, such a conventional flotation device can only display and display only a specific product and a product having a specific condition, and is not suitable for displaying a variety of products (for example, cosmetics, mobile phones, notebooks, etc.) in the air to display to a user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention.

1A and 1B are a perspective view and a side view showing a levitation display device 100 according to an embodiment of the present invention.

As shown in Figure 1a and Figure 1b, the levitation display device 100 according to the present invention is a base member 110, height adjustment member 120, base plate 130, sensor 140, levitation member 150 and a controller (not shown).

2A and 2B are perspective views illustrating a base member 110 and a magnetic force line of the levitation display device 100 according to an exemplary embodiment of the present invention.

As shown in FIGS. 2A and 2B, the base member 110 may be a permanent magnet basically formed in a circular ring shape. However, the base member 110 may be implemented by arranging rod-shaped permanent magnets in a ring form. In addition, the base member 110 may have an N pole at an upper portion and an S pole at a lower portion thereof. Of course, the opposite is also possible. The base member 110 diverges upward when the magnetic lines of force are viewed from the side and converge downward. Here, the N-pole magnetic force lines emitted to the outside of the base member 110 freely converges to the lower S pole, but the N-pole magnetic force lines emitted into the base member 110 become closer to the center of the base member 110. They collide with each other and are therefore pushed into the center and converge to the lower S pole. In view of this macroscopically, it can be said that a magnetic field dome by magnetic lines of force is formed in the inner upper end portion of the base member 110. In this case, when the support member 150 (the upper N pole, the lower S pole) is positioned above the inner center of the base member 110, the support member 150 receives three forces as follows.

(1) Repulsive force between the base member 110 and the support member 150 at the inner central upper portion of the base member 110 (the area where the magnetic field dome is formed).

That is, the magnetic lines of force emitted from the N poles of the base member 110 are inclined to converge to the S poles in the upper portion of the magnetic field dome, from which the magnetic lines become the direction opposite to the direction of the magnetic lines of force emitted from the N poles. In other words, the magnetic lines come out of the north pole, but the direction is reversed, which is the same direction as the magnetic pole of the south pole. And manpower is generated. The present invention utilizes the principle of supporting the support member 150 by using a partial region of the center of the base magnet having such a reverse phenomenon.

(2) attractive force between the base member 110 and the support member 150

The S pole is formed on the lower surface of the support member 150, and the S pole generates an attraction force between the N pole formed on the top surface of the base member 110.

(3) direction holding force of the support member 150

Here, the direction holding force is defined as a force that the support member 150 does not turn over. That is, an N pole is formed on the upper surface of the support member 150, and this N pole generates mutual repulsion with the N pole formed on the upper surface of the base member 110. Therefore, the support member 150 generates a force not to be flipped at an inner upper predetermined distance height of the base member 110.

3A and 3B are perspective and side views illustrating a relationship between the base member 110 and the support member 150 in the levitation display device 100 according to an embodiment of the present invention.

As shown in FIGS. 3A and 3B, the base member 110 and the support member 150 have an N pole formed on an upper surface thereof, and an S pole formed on a lower surface thereof. Therefore, an attractive force acts between the N pole of the base member 110 and the S pole of the support member 150, and the S pole of the magnetic field dome formed above the center of the base member 110 and the S pole of the support member 150. A repulsive force is generated therebetween, and a direction holding force generated by the repulsive force is generated between the N pole of the base member 110 and the N pole of the support member 150.

4A to 4C are exploded perspective views, longitudinal cross-sectional views, and a combined perspective view of the height adjusting member 120 of the levitation display device 100 according to an exemplary embodiment of the present invention.

As shown in FIGS. 4A to 4C, the height adjusting member 120 of the levitation display device 100 is a permanent magnet 121 provided in the inner space of the center of the base member 110 and the permanent magnet 121. It consists of a core 122 surrounding the periphery of, and an electromagnet 123 wound around the core 122.

The permanent magnet 121 may have a rod shape of which an upper surface is an S pole and a lower surface thereof is an N pole. The core 122 has a shape surrounding the side surfaces of the permanent magnet 121 except for the top and bottom surfaces thereof. In addition, the electromagnet 123 has a form surrounding the core 122. Here, the electromagnet 123 is composed of a plurality of wires 123b wound on the bobbin 123a. Of course, the core 122 is coupled to the inside of the bobbin 123a.

The magnetic field trap is formed by the permanent magnet 121 forming the height adjusting member 120 and the electromagnet 123 formed by the current flowing through the wire 123b. That is, when the upper surface of the permanent magnet 121 constituting the height adjusting member 120 is the N pole, and the S pole of the support member 150 is directed toward the base member 110, the support member 150 A magnetic trap for the S pole of the pole is created in the center of the magnetic dome. (See FIG. 1B) In the same principle, when a current flows through the wire 123b so that the N pole is generated on the upper surface of the core 122 of the height adjusting member 120, the core 122 of the height adjusting member 120 is formed. On the top, a magnetic field trap is created in the center of the magnetic field dome. In the present invention, the electromagnetic force by the height adjusting member 120 uses a little force to create the magnetic field trap, most of which is used as the height adjustment or flotation of the support member 150.

Here, the principle that the magnetic field trap by the S pole formed on the lower surface of the support member 150 is made briefly.

The direction of the magnetic field lines emitted from the N pole of the base member 110 is reversed in the upper portion of the magnetic field dome, so that a magnetic field dome that repels the S pole when converged to the S pole of the lower surface is formed (see FIG. 1B). The N pole of the permanent magnet 121 inside the core 122 installed at the center of the member 110 pushes the S-polarized magnetic lines of the magnetic field dome outward (because the magnetic lines cannot converge to the N pole). The magnetic field trap is made in the center, and the higher the N pole intensity (higher magnetic field density), the higher the height of the magnetic field trap, and the larger the surface area of the N pole from which the magnetic field lines are diverged, the wider the magnetic field trap is.

Here, the principle that the support member 150 is not drawn out of the base member 110 as follows.

Magnetic force lines in which the magnetic field lines of the magnetic field dome formed by the N poles of the base member 110 are converging to the S poles are in a repulsive relationship with the S poles of the support member 150. Therefore, the magnetic field dome basically has a force for pushing up the S pole of the support member 150 upward. In addition, when a current is applied to the wire 123b so that the N pole is generated on the upper surface of the core 122 of the height adjusting member 120, the strength of the N pole and the magnetic force line of the permanent magnet 121 installed inside the core 122 is added. Strength becomes stronger In this state, if the S pole of the flotation member 150 faces the lower end and is positioned inside the magnetic field trap, the periphery of the flotation member 150 is surrounded by the magnetic field lines of the magnetic field dome converging to the S pole, thereby increasing the height. If the force of the N-pole magnetic field of the adjusting member 120 and the N-pole magnetic field of the permanent magnet 121 inside the core 122 of the height adjusting member 120 is greater than the force of the magnetic field dome, the support member 150 is lowered. Will be attracted to.

The magnetic field of the base member 110 deformed in the form of a trap is mutually repulsive with the S pole of the flotation member 150, and the N pole and the height adjustment member 120 by the permanent magnet 121 inside the core 122. Due to the mutual attraction relationship with the N pole, the support member 150 is not attracted to the outside of the base member 110. That is, in order for the buoyancy member 150 to be pulled out to the outside of the base member 110, the N pole of the height adjusting member 120 or the N pole of the permanent magnet 121 inside the core 122 is Since the floating member 150 is pulled downward, it cannot pass over.

Subsequently, the base plate 130 is provided on the bottom surface of the base member 110 and the height adjusting member 120. (See FIGS. 1A and 1B)

The base plate 130 may be a metal plate made of a ferromagnetic material. When the base plate 130 is installed on the bottom surface of the base member 110 and the height adjusting member 120, the dome of the magnetic field is repulsed with the S pole of the support member 150. Becomes higher and stronger.

The reason for this is that since the base plate 130 is in contact with the S pole of the bottom surface of the base member 110, all of the upper surface of the metal plate is magnetized to the S pole. Therefore, since the base plate 130 inside the base member 110 is magnetized to the S pole, the entire magnetic field dome which is in the repulsive relationship with the S pole of the support member 150 becomes high and strong.

Meanwhile, the functions of the permanent magnet 121, the core 122, and the electromagnet 123 constituting the height adjusting member 120 will be described below.

 The core 122 has the same function as the core of a general electromagnet. When a current flows through the wire 123b constituting the electromagnet 123 installed outside the core 122, a magnetic field is formed along the direction of the current, and the core 122 inside the ferromagnetic material is magnetized to further strengthen the magnetic field. . And the core 122 has a hole (hole) is formed in a predetermined size on the upper side so that the line of magnetic force of the permanent magnet 121 installed inside the core 122 can diverge to the upper end, according to the size of the hole ( 122) The strength of the magnetic force lines escaping upward is determined. Since the material of the core 122 is made of general soft iron or a material corresponding thereto, the magnetic force line of the permanent magnet 121 installed inside the core is shielded. Here, the permanent magnet 121 inside the core 122 is installed so that the upper portion is the N pole and the lower portion is the S pole, so that a magnetic field trap is formed as described above in the center of the magnetic field dome. When the floating member 150 in the magnetic field trap is positioned so that the upper portion is the N pole and the lower portion is the S pole, the floating member 150 receives little force to the upper and lower portions, but cannot lift it by itself. In other words, it is difficult to adjust the fine force difference only by the permanent magnet 121, and even if it fits, the force of injury is not large enough to place an object for the product display.

However, when a current flows through the electromagnet 123, the balance relationship may be broken and the support member 150 may be pushed up or pulled down. This is because the upper end of the core 122 of the electromagnet 123 may be made of the N pole or the S pole depending on the direction in which the current flows.

The height adjustment method of the support member 150 by the electromagnet 123 is as follows.

As described above, the flotation height of the flotation magnet that balances the force of the upper and lower portions may be determined by the strength of the electromagnet 123 purely. As the lower surface of the support member 150 is the S pole, when the direction of current flows clockwise to the electromagnet 123, the upper portion of the core 122 is magnetized to the N pole to pull down the support member 150, and the current in the counterclockwise direction. When flowing the upper portion of the core 122 becomes the S pole is to push up the support member 150.

Sensor 140 is installed between the height adjustment member 120 and the support member 150, which senses the distance between the height adjustment member 120 and the support member 150, the control unit It serves to transmit.

The sensor 140 may be, for example, a hall sensor 140, which detects a change in the magnetic field emitted from the support member 150, changes the output voltage according to the strength of the magnetic field, and outputs the output voltage to the controller. The output voltage of the sensor 140 is initially determined by the total magnetic field generated by the base member 110, the permanent magnet 121 installed inside the core 122, and other members. The change in the magnetic field generated by the current flow through 123 and the amount of change by the support member 150 are added to produce an output voltage. The signal represented by the change in voltage in the sensor 140 is transmitted to the control unit to control the height of the support member 150, it is possible to levitation of the support member 150 at the desired height.

The controller may control the direction of the current flowing through the electromagnet 123 constituting the height adjusting member 120 according to the magnitude of the signal voltage received from the sensor 140 to raise the support member 150 to a predetermined height. When the support member 150 moves from the A position to the C position as shown in FIG. 1B, the magnitude of the signal voltage transmitted to the controller by the sensor 140 increases linearly. That is, since the magnetic field of the S pole under the support member 150 approaches the sensor 140, the sensitivity is increased, thereby increasing the magnitude of the signal voltage.

On the other hand, with respect to the signal voltage received when the support member 150 is in the AB section, the controller flows a current to the electromagnet 123 constituting the height adjusting member 120 in the clockwise direction to the top of the core of the electromagnet 123 When the N pole is generated, the support member 150 is pulled down in response to the lower S pole of the support member 150. In addition, with respect to the signal voltage received when the support member 150 is in the BC section, the control unit flows a current in the counterclockwise direction to the electromagnet 123 forming the height adjustment member 120 to the top of the core of the electromagnet 123 When the S pole is generated, the support member 150 is pushed upward in response to the lower S pole of the support member 150.

Therefore, the floating height of the flotation member 150 is determined by the set B position, and the flotation member 150 floats with fine vibration at close proximity of the upper and lower portions of the B position. When the sensitivity of the sensor is increased and the driving speed (current direction change speed) is increased by the controller, the vibration is not recognized by the human eye.

Here, the floating force of the support member 150 is determined by the current constituting the height adjustment member 120, it can be displayed by placing a product of any weight on the support member 150. In addition, when the support member 150 is above the A position or below the C position, the control unit may automatically turn off the current applied to the electromagnet 123 to prevent power consumption.

Here, such a control unit may be implemented by conventional analog circuits and / or digital circuits, or may be controlled by a programmable computer. The function of the controller can be easily implemented by those skilled in the art after reading the specification, detailed description thereof will be omitted.

Subsequently, the levitation control method through the control unit will be described in more detail.

First, the up and down vibration of the support member 150 can move the support member 150 up and down by programming the B position to change up and down with time in the magnetic field trap. Up and down operation of can be implemented.

On the other hand, the permanent magnet 121 inside the core 122 constituting the height adjusting member 120 has another function. That is, in the event of a power outage while the goods are displayed on the flotation member 150 for the display of the goods, the flotation member 150 is attached to the upper part of the permanent magnet 121 in the core 122 to function as a device for protecting the goods. Have In order to have such a function, the pulling force by the permanent magnet 21 inside the core 122 is slightly larger than the lifting force by the magnetic field dome of the base member 110 so that the floating member 150 is trapped in the trap during power failure. It is pulled down to stick to the permanent magnet 121 in the core 122 to protect the product.

5A and 5B are perspective views illustrating a levitation display device 200 according to another embodiment of the present invention, and a side view of a magnetic force line.

As shown in FIGS. 5A and 5B, an auxiliary member 260 may be further installed between the base member 110 and the height adjusting member 120 to increase the lifting height of the lifting member 150. The auxiliary member 260 may be a ring-shaped magnet. In addition, the auxiliary member 260 is installed so that the S pole is directed upward, and the N pole is directed downward. Then, the magnetic field trap can be made higher by the auxiliary member 260 with respect to the support member 150 having the lower surface of the S pole.

Basically, the lift height of the support member 150 is determined by the height of the magnetic field dome of the base member 110, but by installing another auxiliary member 260 with the S pole facing upward, the existing height of the magnetic field dome is moved upward. Will rise further. Therefore, the magnetic field barrier with respect to the S pole of the flotation member 150 rises in two stages around the periphery of the magnetic field trap, thereby making the magnetic field trap deeper, thereby raising the floating height of the flotation member 150.

6A and 6B are cross-sectional views illustrating a base member 310 and a magnetic force line in a levitation display device according to another exemplary embodiment of the present invention.

As shown in FIGS. 6A and 6B, the base member 310 may have an upper inner diameter larger than a lower inner diameter. That is, the base member 310 may be formed in a shape where the upper N pole diameter is wider and the lower S pole diameter is smaller. In this way, the base member 310 is in a state where the magnetic field divergence is inclined, and the height of the magnetic field dome is made higher than that of the base member 310 of the same size.

7A to 7C are combined perspective views and exploded perspective views illustrating various types of levitation members 450, 550, and 150 of the levitation display device according to another exemplary embodiment of the present disclosure.

First, as shown in FIG. 7A, the support member 550 may include a plastic first housing 451, a first permanent magnet 452 in the form of a disk coupled to the first housing 451, and the first permanent magnet ( The second housing 453 in close contact with the 452 and the second permanent magnet 454 in the form of a rod smaller than the diameter of the first permanent magnet 452 coupled to the second housing 453 may be formed.

In addition, as shown in Figure 7b, the support member 550 is a plastic first housing 551, the first permanent magnet 552 in the form of a ring coupled to the first housing 551, the first permanent magnet A second housing 553 in close contact with 552 and a rod-shaped second permanent magnet 554 smaller than the diameter of the first permanent magnet 552 coupled to the second housing 553 may be formed.

In addition, as shown in Figure 7c, the support member 150 may be a rod-shaped permanent magnet.

Here, the above-described floating member 450, 550, 150 may be satisfactorily floated when basically having the same polarity as the base member (110). To this end, if the base member 110 is installed so that the upper portion is the N pole, the lower portion is the S pole, the support members 450, 550, 150 are also configured so that the upper portion is the N pole, the lower portion is the S pole. However, the support members 450, 550 and 150 may be injured even though they have a different polarity than the base member 110, although the support heights may be different. That is, if the base member 110 is installed so that the upper portion is the N pole, the lower portion is the S pole, the support members 450, 550, 150 may also be configured such that the upper portion is the S pole and the lower portion is the N pole.

In addition, the support member may be a rod-shaped permanent magnet, but as described above, permanent magnets 454 and 554 in the form of disks or rings may be added. When the disk-shaped or ring-shaped permanent magnets 454,554 are added, the protruding rod-shaped permanent magnets 454,554 are fixed in the magnetic field trap, and the added disk-shaped or ring-shaped permanent magnets 452,552 have a base. The direction holding force and the floating force can be increased in the upper portion of the magnetic field dome formed by the member 110, which is efficient for displaying heavy goods.

8A and 8B are front and rear perspective views illustrating a rotating member 660 of the levitation display device 600 according to another embodiment of the present invention.

In this way, when the control unit controls the motor 663, the ring member 661 rotates in a predetermined direction, whereby the first permanent magnet 662 provided on the ring member 661 and the support member ( As the second permanent magnets 664 installed at 450 interact with each other, the support member 450 rotates in a predetermined direction. That is, minute attraction or repulsive force is generated in the first permanent magnet 662 and the second permanent magnet 664. In this state, when the ring member 661 is slowly rotated by the motor 663, the first permanent magnet The support member 450 is also slowly rotated by the interaction of the 662 and the second permanent magnet 664.
