Abstract

The present invention minimizes the noise caused by the frictional force due to the repulsive force of the permanent magnet, and the comfort and magnetic force of the body as if floating in the air by the magnetic force, more effectively than the conventional spring buffer function of the bed or sofa. It can help your health by increasing circulation and oxygen levels. In addition to permanent magnets, solenoid electromagnets are installed on the floor to receive power from the power supply, and the pressure sensor installed between the upper plates allows the user to select the degree of cushion by adjusting the strength of the current to adjust the desired pressure for each part. do.

Description

Magnetic Levitation System for Bed or Chair

Cushion device, bed technology, magnetic levitation, magnet technology.

Magnetism is the property of attracting fragments or acting on current, and such magnetic objects are called magnets. Magnets can be divided into temporary magnets and permanent magnets according to magnetism by external magnetic fields. In other words, the temporary magnet is the magnetism disappears when the external magnetic field is removed like the iron core of the electromagnet, the permanent magnet is retained for a long period of time even if the external magnetic field is removed once the magnetic. Dividing the magnet according to the shape, there are rod-shaped bar magnets and U-shaped horseshoe magnets. In addition, there are also needles that allow small permanent magnets such as compasses to rotate freely in the horizontal plane. Permanent magnets have different chemical and physical properties from different materials.

Magnets made of aluminum, nickel and cobalt alloys, called Alico magnets, are divided into anisotropic and isotropic. Spica magnets, for example, have excellent reproducibility in the high frequencies in their frequency response. Even in the case of analog instruments, the linearity is good when going up to a high range, so the advantage is that the temperature coefficient is good, but the disadvantage is that the cobalt (Co) price of raw materials is expensive and fluctuates, which limits the use of some parts. Ferrite Magnet: It is divided into anisotropic and isotropic, and the production method is divided into wet method and dry method, and it is divided into radial anisotropy, polar anisotropy, and general anisotropy according to the magnetic field direction. The price is cheap, but the magnetic properties are difficult to apply to the product, and the temperature coefficient is poor and there are problems to mass production. However, recently developed rare earth magnets are applied in many industries because of their excellent magnetic properties and strong strength.

NdFeB (neodymium) magnets and SmCo (samarium cobalt) magnets are divided into SmCo-Mag's powerful magnets with the invention of NdFeB magnets, but other materials have already been developed due to the high cost and instability of raw materials. These uses are maglev trains. Wind power generator. Applications such as driving motors of electric vehicles have been applied in various ways. The neodymium magnet was very strong and the temperature coefficient was at first a problem, but now it can be used stably up to 200 ℃. Korea was initially unable to produce high prices and technical know-how due to patent issues. Samarium cobalt magnets are not a problem for temperature, but Co has been converted to NdFeB-magnets due to its high price and high price fluctuations. The temperature coefficient is quite good and it can be used up to 350 ℃, so it is used in high-tech field in Japan.

Bond magnet is a magnet made by mixing the powder of self-magnet with resin, and it is a magnet that adds plastic to magnet to improve friction.

Through the present invention, in order to minimize the noise caused by the frictional force by the repulsive force of the permanent magnet more effectively than the conventional way of acting as a shock absorber of the bed or sofa with a magnet to feel comfortable to float in the air The purpose is to create a well-arranged cushioning device.

In order to achieve the above object, the magnets are arranged in the same pole so that the N pole meets the N pole with the N pole so that a repulsive force is generated, thereby using the repulsive force to have a spring-like elastic force. To secure the magnet, make a hole in the circular magnet and fix it to the rod shaft. To reduce friction, Teflon, a plastic with low coefficient of friction, is coated around the magnet hole and the shaft. The magnets are arranged on several rod shafts, and the magnet poles are pushed up and down at regular intervals and kept at a constant distance so as not to be influenced by each other. Since the degree of elasticity by this magnet is affected by the coercive force and magnetic force of the magnet, select the type of magnet according to how softly the magnetic levitation is to be caused.

Although it is more difficult to manufacture than the existing foam mattress or spring mattress, it solves the problem that the foam or spring loses its elasticity due to the loss of resilience over time, so that it does not feel the comfort of the first time and hear the noise by friction. Done. Above all, the comfort and magnetic force that seems to be floating in the air by the magnetic force can have an effect to increase the blood circulation or oxygen concentration of our body can help health. In addition to permanent magnets, solenoid electromagnets can be installed on the floor to receive power from the power supply, and the degree of cushion can be selected by adjusting the strength of current so that the desired pressure can be adjusted for each part according to the pressure sensor installed between the upper plates. To be.

In the present invention, the forces pushing against each other by using the repulsive force of the magnet should act against gravity, so a samarium (Sm) or neodynium (Nd) magnet, which is a strong permanent magnet capable of supporting weight, should be used. These magnets (1-2B) are drilled and teflon-coated to reduce the frictional force around them and inserted into the rod fixing shaft (1-2A) so that the same poles face each other. This rod fixed shaft (1-2A) also uses teflon or low friction material to prevent noise. Place the bar rod fixing shafts (1-2A) according to the size of the bed. The solenoid electromagnet (1-2C) is installed on the lower plate (1-3) of the bed or sofa so that the pressure of the upper plate can be adjusted by using the repulsive force by the electromagnet. If you install a pressure sensor (1-5) between the top plate, you can press the bed to see the pressure distribution as the intensity of the sensor, while adjusting the pressure of the desired area to the intensity of the current, or use the vibration function to produce a massage effect. In order to operate the electrostatic cushion by the part of the electromagnet, the computer control system (1-4) function can be used to effectively store and use the desired part pressure.
