Description

  The present invention relates to a magnetic levitation bed having multiple functions for assisting exercise, rest, sleep, medical treatment and the like.

  Many beds with modern massage functions are water beds or air cushion beds, which consist of a bed frame and a bed base that supports the bed frame. It is driven by a mechanism such as a belt or a chain, or the bed frame is moved up and down, back and forth, and left and right by a hydraulic lifting mechanism.

  In the conventional bed using the above-mentioned mechanical or electromechanical drive mechanism, it is necessary to drive by a low speed motor or a hydraulic motor when moving, but in the operation process, the bed user is caused by wear and failure of the mechanism. May cause injury. In addition, the motor consumes a lot of electricity and noise, and forgetting to shut off the power after use, or the motor overheating due to long-term use of the mechanism may cause a lot of economic damage. As a result, users are terrified of the massage bed and are currently using it or refraining from purchasing it. Such a situation needs to be improved immediately.

  The present invention uses a magnetic or electromagnetic drive mechanism instead of a mechanical or electromechanical drive mechanism to move the bed frame up and down, back and forth, right and left, etc. The purpose is to provide a multi-function magnetic levitation bed with less.

  The magnetic levitation bed according to the present invention includes a bed bottom and a bed frame placed on the bed bottom. The bed base receives a plurality of electromagnets having a magnetic pole changing circuit, a first low-speed motor, a second low-speed motor, and a signal for designating the movement direction of the bed frame to the left, right, front, back, or top. And a power control box for determining the power supply destination to be one of the electromagnet matrix, the first low speed motor, and the second low speed motor. In the bed frame, with the bed frame placed on the bed base, a permanent magnet that overlaps the electromagnet, and a first motor on the bed base around a rotational axis in the front-rear direction. A first cam mechanism that is combined so as to be interlocked with the first cam that is rotated, and a second that is combined so as to be interlocked with a second cam that is rotated around the rotation axis in the left-right direction by the second motor of the bed bottom. And a cam mechanism. The power control box supplies power to the electromagnet when an up / down motion command signal is input, so that the bed frame floats from the bed bottom, and the magnetic pole is alternately changed by the magnetic pole changing circuit. When the left and right direction motion command signal is input, the first motor is driven. When the front and rear direction motion command signal is input, the second motor is driven, and the electromagnet is supplied with power to the bed frame. Are floated from the bed bottom and the magnetic poles are alternately changed by the magnetic pole changing circuit. The above configuration is a feature.

  The bed frame is provided with a movement end detection means for outputting a terminal end detection signal when reaching a predetermined movement end in the front-rear direction and the left-right direction with respect to the bed bottom, and the power control box is provided with a left-right movement command signal. Is input to the first motor, and when a longitudinal motion command signal is input, the second motor is driven, and power is supplied to the electromagnet to lift the bed frame from the bed base. It is preferable that the magnetic pole is changed by the magnetic pole changing circuit every time an end detection signal is received from the movement end detection means.

  The bed base is provided with a base, the base is provided with a support, and the leg frame and the bed frame are attached to the bed frame on the lower side of the bed frame. It is desirable that a cushion that contacts the column is provided.

  The bed base is preferably provided with a safety suspension arm for limiting the width of the bed frame swing, and an electromagnetic wave shielding member is provided so that the user is not affected by the electromagnetic wave.

  The general magnetic levitation operating system is divided into the following several types. (a) Permanent magnet rejection force levitation, (b) Permanent magnet and electromagnet combination levitation, (c) Permanent magnet mixing levitation, (d) Superconducting magnet mixing levitation, or (e) Permanent magnet compensation technology.

  The magnetic levitation bed of the present invention employs a levitation mechanism that uses a "magnetic displacement force" and a "magnetic attraction force" by a magnet provided on the bed base and a bed frame magnet, and further by a combination of a permanent magnet and an electromagnet. "Compensation magnetism and induced magnetism magnetic compensation technology" is added. This method has high levitation force, low energy consumption, simple control, safe and reliable, and is completely feasible in terms of technology. In addition, the cost is low.

More specifically, the magnetic levitation bed of the present invention has the following features.
First, safety is extremely high.
The bed frame does not have any power source or power device, and when the electromagnetic operation of the bed base is stopped, the bed frame rubber mat and the bed base come into natural contact. It has an insulating effect on the outside that supports the bed frame, and the bottom of the magnetic levitation bed is driven by low voltage power (110 to 240 volts) and does not require high voltage or large current. Therefore, there is no fear that the user will get an electric shock. Also, there is no transmission mechanism such as links, gears, belts or chains between the bed frame and the bed base, and no motor drive is required, and the entire bed frame floats regularly on the bed base. And can exercise. Therefore, it is possible to completely escape from the opportunity to injure people when the traditional massage bed interlocking mechanism fails.
Furthermore, since the health of the user is disturbed unless the magnetic field generated by the electromagnetic coil is effectively shielded, the present invention uses a shielding member made of a shielding material called “industrial pure iron” (for example, EFE). The magnetic levitation bed of the present invention is extremely safe because the magnetic field on the bed frame is effectively reduced to within 10 gauss, thereby ensuring the safety of the user.

Second, energy consumption is low.
When this magnetic levitation bed is operated at 200 kilograms per page, the electricity consumption is about 0.1 KWH and no thermal energy is generated, so there is no risk of fire.

3. Less maintenance is required.
There is no interlocking mechanism between the bed frame and bed base of this magnetic levitation bed, and there is no mechanism that makes direct contact between the movement of the bed frame and the bed base. Only the universal safety suspension arm to be controlled is connected, and there is no vibration during operation, so it is comfortable to use. The operation is performed without wear and maintenance is mainly concentrated on the electronic circuit, so that a large amount of physical labor is not required.

Fourth, there is no pollution.
When this magnetic levitation bed is operated, there is no emission of harmful gas and no noise is generated, so the pollution of the environment is equal to zero.

5. Power supply is easy (electromagnetic induction power supply system).
When the magnetic levitation bed is activated, the bed frame and bed base are in a non-contact state, and when the bed frame of the magnetic levitation bed requires electricity for lighting and sound, etc. Necessary electric power can be obtained by wireless electric power supply technology by electromagnetic induction of the coil of the bed base and the coil of the bed frame.

Next, embodiments of the present invention will be described with reference to the drawings.

The magnetic levitation bed according to the present invention comprises a bed frame 1 and a bed base 2.
As shown in FIGS. 1 and 2, the bed frame 1 is composed of a frame having an appropriate rigidity. On the bed frame 1, a head plate, a side plate, a leg plate, sound, a remote controller, a mattress and the like are attached as required. A plurality of downwardly extending legs 14 are provided below the bed frame 1, and a cushion 15 is provided below the bed frame 1. In addition, a plurality of permanent magnet matrices 11 are provided at appropriate locations on the lower side of the bed frame 1, and a first cam combination mechanism 12 is provided at the lower side of the bed frame 1 with the bed frame 1 Second cam combination mechanisms 13 are respectively installed at locations close to the lower central axis.

  3 and 4 show a bed base 2 according to the present invention. The bed base 2 is composed of a suitable rigid frame, which basically includes a base 21 that can be placed firmly on the floor surface, and a plurality of sets of struts 22 are erected on the base 21. A safety suspension arm 23 is attached to an appropriate position of each column 22. A power control box 24 and a plurality of sets of electromagnet matrices 25 are provided at appropriate locations on the bed base 2, and the positions of the electromagnet matrices 25 correspond to the positions of the permanent magnet matrix 11 on the bed frame 1. The bed base 2 is further provided with a first low-speed motor 26 and a second low-speed motor 27, and the first and second low-speed motors 26 and 27 are provided with a first cam 261 and a second cam 271 respectively. The first cam 261 and the second cam 271 respectively correspond to the first cam combination mechanism 12 and the second cam combination mechanism 13 provided in the bed frame 1.

  When the bed frame 1 is mounted on the bed base 2 and the cushion 15 contacts the support 22, the first cam 261 and the second cam 271 are combined with the first cam combination mechanism 12 and the second cam combination mechanism 13, respectively. At the same time, the electromagnet matrix 25 and the permanent magnet matrix 11 overlap each other.

     On the bed base 2 is an upper camera 28 that constitutes an end-of-motion detection means that outputs a terminal end detection signal when the bed frame reaches a predetermined end of motion in the front-rear direction and the left-right direction with respect to the bed base. A lower camera 29 is provided. The bed base 2 is further provided with a receiver for receiving a remote control signal (not shown).

The operation control method when using the magnetic levitation bed of the present invention is as follows.
When the remote control signal receiver and the power control box 24 on the bed base 2 shown in FIG. 2 receive the start signal sent from the remote controller by the user, the electromagnet matrix 25 starts immediately and the electromagnet matrix 25 Since the generated magnetic force forms a maglev mechanism with the magnet matrix 11, the bed frame 1 is easily lifted, and the bed frame 1 and the cushion 15 are separated from the support 22 of the bed base 2 and the upper side of the bed base 2 To surface.

  When the remote control signal receiver and the power control box 24 receives the left / right movement command signal sent from the remote controller to move the bed frame 1 in the left / right direction, it immediately starts the first low speed motor 26. Then, the first cam 261 is moved and rotated once on the first cam combination mechanism 12 to move the bed frame 1 slightly to the right. At this time, the bed frame 1 reaches the end of motion. The upper camera 28 and the lower camera 29 that constitute the detection means for detecting that the bed frame 1 transmits, for example, a right end detection signal to the remote control signal receiver and the microprocessor of the power control box 24. The microprocessor immediately changes the magnetic pole of the electromagnet matrix 25 via the magnetic pole changing circuit. The evacuation levitation mechanism and the suction levitation mechanism act alternately on the magnetic poles of the permanent magnet matrix 11, thereby achieving the effect of left-right swinging. In order to avoid that the swing width is too large, the safety suspension arm 23 of the magnetic levitation bed restrains the bed frame 1 to operate within the range of the left and right dead points at any time.

When the remote control signal receiver and the power control box 24 receives the forward / backward swing signal transmitted from the remote controller, it immediately starts and operates the second low-speed motor 27, and further moves the second cam 271 to operate the first cam 271. One turn on the two-cam combination mechanism 13 moves the bed frame 1 slightly backward. At this time, the upper camera 28 and the lower camera 29 transmit the signal that the bed frame 1 has moved back to the microprocessor of the remote control signal receiver and the power control box 24, and the microprocessor immediately transmits the magnetic pole of the electromagnetic matrix 25. Change. The evacuation levitation mechanism and the suction levitation mechanism act alternately on the magnetic poles of the permanent magnet matrix 11, thereby achieving a back-and-forth swing effect. In order to avoid the swinging width being too large, the safety suspension arm 23 of the magnetic levitation bed also checks the bed frame 1 to operate within the range of the front and rear dead points.
When the remote control signal receiver and the power control box 24 receives the vertical motion command signal transmitted from the remote controller, the microprocessor immediately changes the magnetic pole of the electromagnet matrix 25, and the magnetic pole of the permanent magnet matrix 11 The effect of vertical vibration is achieved by the interaction between the excretion and suction.
When the user receives a stop signal transmitted from the remote controller to the remote control signal receiver and the power control box 24, the power of the electromagnet matrix 25 is immediately shut off, and in this case, the electromagnet matrix 25 is activated by the capacitance cushion. The bed frame 1 loses the support of the magnetic excision action, and the cushion 15 falls on the column 22 of the bed bottom 2 to recover the stationary state.

    In the above embodiment, the magnet of the bed frame 1 has been described as a permanent magnet, but it may be an electromagnet.

  The magnetic levitation bed according to the present invention is particularly suitable for use in elderly people, strokes, persons who have become disturbed or unable to act due to unexpected injuries, infants, plant humans and the like.
