Description

Technical Field

[0001] This utility model relates to the field of bed frame design technology, and in particular to a magnetic levitation bed frame. Background Technology

[0002] Existing bed frames are generally slatted bed frames, which consist of multiple ribs spaced apart on a main frame. Slatted bed frames offer a degree of overall flexibility and are more ergonomic than ordinary flat bed frames. Therefore, users who prioritize sleep comfort usually choose slatted bed frames.

[0037] This utility model discloses a magnetic levitation bed frame to solve the technical problem that existing bed frames cannot adjust the softness and hardness of the support.

[0038] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1 to 5 The present invention provides a magnetic levitation bed frame, including a frame 1, a magnetic levitation device and several rib strips 2;

[0040] The magnetic levitation device is disposed between the frame 1 and the rib strip 2;

[0041] The magnetic levitation device includes a controller, an elastic element 4, a magnetic base, and a floating block 3;

[0042] The magnetic base is mounted on the frame 1, and the floating block 3 is mounted on the rib strip 2;

[0043] The floating block 3 is connected to the magnetic base via the elastic element 4. The magnetic base provides a repulsive force to the floating block 3 to keep it suspended. The controller is electrically connected to the magnetic base to control the magnetic force of the magnetic base, thereby adjusting the suspension height of the floating block 3 to change the elastic force of the elastic element 4.

[0044] It should be noted that the controller mentioned above can be a microcontroller or other control device, which will not be described in detail in this embodiment.

[0045] With the above design, the user can control the magnitude of the magnetic force provided by the magnetic base to the floating block 3 through the controller, thereby adjusting the elastic force of the elastic element 4 to change the support stiffness of the rib strip 2, so that the bed frame can meet the personalized needs of different users for different support stiffness.

[0046] Furthermore, in this embodiment, the floating block 3 is the first magnet, specifically a permanent magnet;

[0047] The magnetic base includes a first fixed base 5, an electromagnet 7, and a second magnet 8, the second magnet 8 being a permanent magnet.

[0048] The first fixed base 5 is mounted on the frame 1, the bottom end of the elastic element 4 is connected to the first fixed base 5, and the top end of the elastic element 4 is connected to the floating block 3.

[0049] The controller is electrically connected to the electromagnet 7. The electromagnet 7 and the second magnet 8 are mounted on the first fixed base 5, and the second magnet 8 is arranged around the electromagnet 7. The magnetic poles of the second magnet 8 facing the first magnet are the same as the magnetic poles of the first magnet facing the second magnet 8. When the electromagnet 7 is energized, it can generate magnetic force to control the levitation height of the floating block 3, thereby changing the elastic force of the elastic member 4.

[0050] It should be noted that, through the above design, the electromagnet 7 in this embodiment can generate an attractive or repulsive force on the first magnet when current is applied. Furthermore, by controlling the magnitude of the applied current through the controller, the magnetic force of the electromagnet 7 can be changed, thereby changing the magnetic force on the first magnet. By controlling the direction of the applied current through the controller, the magnetic poles of the electromagnet 7 can be changed, thereby achieving attraction or repulsion on the first magnet.

[0051] When the user needs to adjust the support stiffness of the bed frame to be softer, the controller can make the electromagnet 7 generate a repulsive force against the first magnet, and reasonably adjust the current of the electromagnet 7 so that the first electromagnet 7 generates a repulsive force against the first magnet, causing the floating block 3 and the rib strip 2 to rise and stretch the elastic element 4. Since the elastic element 4 is stretched relative to the normal state, the support stiffness of the bed frame becomes softer at this time.

[0052] When the user needs to adjust the support stiffness of the bed frame to be harder, the controller can make the electromagnet 7 attract the first magnet and reasonably adjust the current of the electromagnet 7 so that the first electromagnet 7 attracts the first magnet, so that the floating block 3 and the rib strip 2 overcome the repulsive force of the second magnet 8 and descend, thereby compressing the elastic element 4. Since the elastic element 4 is compressed relative to the normal state, the support stiffness of the bed frame becomes harder.

[0053] It should also be noted that there can be multiple second magnets 8. Multiple second magnets 8 are arranged around the electromagnet 7 to avoid the second magnets 8 affecting the operation of the electromagnet 7. In addition, the magnetic poles of the second magnets 8 facing the first magnet are the same as the magnetic poles of the first magnet facing the second magnets 8. Simply put, when the magnetic pole of the second magnet 8 facing the first magnet is the N pole, the magnetic pole of the first magnet facing the second magnet 8 is also the N pole, and when the magnetic pole of the second magnet 8 facing the first magnet is the S pole, the magnetic pole of the first magnet facing the second magnet 8 is also the S pole.

[0054] Furthermore, the magnetic base in this embodiment also includes a magnetic sensor 6;

[0055] The magnetic sensor 6 is mounted on the first fixed base 5, and the electromagnet 7 and the second magnet 8 are both disposed on the magnetic sensor 6. The magnetic sensor 6 is electrically connected to the controller. The magnetic sensor 6 is used to sense the magnetic field strength of the first magnet and output a voltage signal to the controller.

[0056] It should be noted that, through the above design, the magnetic sensor 6 can detect the magnetic field strength of the magnetic field where the first magnet is located in real time, and convert the magnetic field strength into a voltage signal and output it to the controller. The user can obtain the current magnetic field strength based on the voltage signal, and then adjust the support stiffness of the bed frame according to their own needs.

[0057] Specifically, the magnetic sensor 6 mentioned above is a Hall sensor in the prior art.

[0058] Furthermore, to avoid being affected by magnetic fields, the elastic element 4 in this embodiment is specifically a plastic spring.

[0059] Furthermore, in this embodiment, the rib strip 2 has a first end and a second end that are arranged opposite to each other, wherein the magnetic levitation device is provided between the first end and the frame 1 and between the second end and the frame 1.

[0060] It should be noted that the above design ensures that the forces on the two ends of the rib strip 2 are evenly distributed, allowing users to accurately adjust the support stiffness of the bed frame.

[0061] Furthermore, in this embodiment, the first end and the second end of the rib strip 2 are both provided with a second fixing seat 9. The second fixing seat 9 is recessed inward to form a receiving groove with the opening facing downward, and the floating block 3 is installed in the receiving groove.

[0062] It should be noted that the above design provides installation space for the floating block 3 and prevents the floating block 3 from being exposed on the outer side of the rib strip 2.

[0063] Furthermore, to prevent the first fixing seat 5 and the second fixing seat 9 from being affected by the magnetic field, which could cause deviations in the adjustment of the bed frame support firmness, both the first fixing seat 5 and the second fixing seat 9 are made of carbon steel. For example, stainless steel or other carbon steel materials, or composite materials, such as carbon fiber, can also be used.

[0064] In addition, the frame 1 in this embodiment can also be made of carbon fiber or carbon steel, and the rib strips 2 in this embodiment can be made of wood.

[0065] Furthermore, the magnetic levitation bed frame in this embodiment also includes a guide assembly, through which the rib strips 2 are movably connected to the frame 1.

[0066] Furthermore, in this embodiment, a guide rod (not shown in the figure) is provided on the frame 1, and a guide hole (not shown in the figure) is provided on the rib strip 2, and the guide rod is slidably connected in the guide hole;

[0067] Alternatively, the rib strip 2 may be provided with a guide rod (not shown in the figure), and the frame 1 may be provided with a guide hole (not shown in the figure), with the guide rod slidably connected in the guide hole.

[0068] It should be noted that, due to the influence of repulsive force, the rib strip 2 will be displaced in the vertical direction relative to the frame 1, i.e., a lifting and lowering motion. Therefore, through the above design, the rib strip 2 can be made to move more smoothly and steadily during the displacement process.

[0069] Furthermore, in this embodiment, there can be multiple rib strips 2. Through the design of the magnetic levitation device described above, each rib strip 2 can be individually supported with adjustable firmness, allowing users to adjust it according to the comfort needs of different body parts.

[0070] The above provides a detailed description of a magnetic levitation bed frame provided by this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
