DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] In this application, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0033] Sofas have become a necessary piece of furniture for many families. Currently, most of the finished sofas on the market have a fixed height and their backrest height cannot be changed. It is impossible to make the same product suitable for people of all heights, which leads to a small number of users suitable for a single product and a limited consumer group.

[0034] Therefore, in one embodiment, a magnetic levitation component is arranged between the bottom of the sofa body and the top of the sofa base, and the sofa body is adjusted in height by the effect of magnetic levitation. Specifically, the magnetic levitation component has electromagnets with the same polarity arranged relatively in the vertical direction between the bottom of the sofa body and the top of the sofa base. However, when the user sits on it or the sofa body is suspended and lifted, it may sway left and right, and the sofa body may have a certain deviation in the horizontal direction in the suspended state, making the sofa body unstable and the user experience poor.

[0035] In view of this, some embodiments of the present application provide a magnetic levitation lifting sofa, which not only facilitates the adjustment of the suspension height of the sofa body, but also has a wider range of applicability to users, and can also ensure that the sofa body remains stable in the horizontal direction. The sofa body can remain stable when the user sits on it or when it is suspended and lifted, providing a better user experience.

[0036] The present application is described in detail below through specific embodiments:

[0037] like Figure 1 and Figure 2 As shown, the magnetic levitation lifting sofa of the embodiment of the present application includes a sofa body 1, a sofa base 2 and a magnetic levitation component 3. The bottom of the sofa body 1 is provided with a groove 11, the sofa base 2 is arranged in the groove 11, and the magnetic levitation component 3 includes a first magnet component 31 and a second magnet component 32. Since the first magnet component 31 needs to adjust the height of the sofa body 1 according to the magnitude of the magnetic force, the first magnet component 31 is an electromagnetic component. The first magnet component 31 is arranged between the bottom wall of the groove 11 of the sofa body 1 and the top of the sofa base 2, and is used to make the sofa body 1 in a suspended state when power is turned on. The second magnet component 32 is arranged between the side wall of the groove of the sofa body 1 and the side wall of the sofa base 2, and is used to stabilize the position of the sofa body 1 in the horizontal direction.

[0038] The magnetic levitation lifting sofa provided in the embodiment of the present application is configured such that the sofa base 2 is arranged in the groove 11 at the bottom of the sofa body 1, and the sofa body 1 is magnetically suspended and separated by arranging a magnetic levitation component 3 between the groove 11 of the sofa body 1 and the sofa base 2. Specifically, the first magnet component 31 is arranged between the bottom wall of the groove 11 of the sofa body 1 and the top of the sofa base 2. The first magnet component 31 is an electromagnetic component. Therefore, by adjusting the magnetic force of the first magnet component 31 when power is turned on, the suspension height of the sofa body 1 can be easily adjusted. The suspension height of the sofa body 1 can be adjusted according to the needs of people of different heights, and the application range for users is wider. Since the second magnet component 32 is arranged between the side wall of the groove of the sofa body 1 and the side wall of the sofa base 2, the sofa body 1 can be kept stable in the horizontal direction under the magnetic force of the second magnet component 32. When a person sits on the sofa or the sofa is suspended and lifted, it can remain stable, and the user experience is better.

[0039] Specifically, the first magnet assembly 31 includes an upper magnet disposed on the bottom wall of the groove 11 of the sofa body 1 and a lower magnet disposed on the top of the sofa base 2. The upper magnet and the lower magnet can both be electromagnets, or one of the upper magnet and the lower magnet can be an electromagnet and the other can be a permanent magnet. When the upper magnet and the lower magnet are both electromagnets, Figure 1As shown, the first magnet assembly 31 specifically includes a first electromagnet 311 and a second electromagnet 312. The first electromagnet 311 is arranged on the bottom wall of the groove 11 of the sofa body 1 to form an upper magnet. Correspondingly, the second electromagnet 312 is arranged on the top of the sofa base 2 to form a lower magnet, so that the first electromagnet 311 and the second electromagnet 312 are arranged relative to each other in the vertical direction, and the first electromagnet 311 and the second electromagnet 312 are arranged relative to each other with the same poles. In this way, since both the upper magnet and the lower magnet are electromagnets, the electromagnetic force between the first electromagnet 311 and the second electromagnet 312 is easy to control, and the adjusted electromagnetic force is more accurate. Therefore, the adjustment of the suspension height of the sofa body 1 is more accurate, and the user experience during use and operation will be better.

[0040] Since the first magnet assembly 31 is an electromagnetic assembly, it is necessary to energize the first magnet assembly 31 when in use. Figure 3 As shown, the magnetic levitation lifting sofa also includes a controller 4, which is specifically electrically connected to the first magnet assembly 31 to control the electromagnetic force of the first magnet assembly 31 to adjust the suspension height of the sofa body 1. The controller 4 can be operated to adjust the suspension height of the sofa body 1 according to the needs of people of different heights. The operation is convenient, and the electrical control through the controller 4 can more accurately adjust the suspension height of the sofa body 1.

[0041] Since the second magnet assembly 32 only needs to ensure that the sofa body 1 has a good stabilizing effect in the horizontal direction, the second magnet assembly 32 can have a variety of implementation methods. For example, the second magnet assembly 32 is a permanent magnet assembly, and permanent magnets are arranged relatively horizontally on the groove side walls of the sofa body 1 and the side walls of the sofa base 2. The two parts of the permanent magnets are arranged with the same poles facing each other. The relatively arranged permanent magnets make the sofa body 1 stable in the horizontal direction. In this embodiment, the second magnet assembly 32 is set as an electromagnetic assembly. Specifically, the second magnet assembly 32 includes a third electromagnet 321 and a fourth electromagnet 322. The third electromagnet 321 is set on the side wall of the groove of the sofa body 1, and the fourth electromagnet 322 is set on the side wall of the sofa base 2, so that the fourth electromagnet 322 and the third electromagnet 321 are arranged opposite to each other in the horizontal direction, and the fourth electromagnet 322 and the third electromagnet 321 are arranged opposite to each other with the same pole. By setting the second magnet assembly 32 as an electromagnetic assembly, the horizontal position of the sofa body 1 can also be adjusted after power is turned on, which is convenient to use, and the electromagnet is easy to adjust the electromagnetic force, and the adjustment accuracy is higher.

[0042] Since the second magnet assembly 32 is also an electromagnetic assembly, the second magnet assembly 32 also needs to be powered on. In this embodiment, the controller 4 is electrically connected to the second magnet assembly 32 at the same time to control the electromagnetic force of the second magnet assembly 32. In this way, the controller 4 is connected to both the first magnet assembly 31 and the second magnet assembly 32 at the same time, so that both can be controlled at the same time. Specifically, during operation, since the first magnet assembly 31 needs to control the sofa body 1 to suspend and lift, the electromagnet of the first magnet assembly 31 is set to a high-power electromagnet, and the second magnet assembly 32 plays a stabilizing role for the sofa body 1 in the horizontal direction. Therefore, the second electromagnet is set to a low-power electromagnet to play a stabilizing role, which saves energy.

[0043] The groove sidewall of the sofa body 1 and the sidewall of the sofa base 2 can be implemented in a variety of ways, such as, the groove sidewall of the sofa body 1 can be an annular groove sidewall, and correspondingly, the sofa base 2 is set as a columnar body, the third electromagnet 321 is annularly arranged on the groove sidewall of the sofa body 1, and the fourth electromagnet 322 is annularly arranged on the sidewall of the sofa base 2. In this embodiment, the groove sidewall of the sofa body 1 includes a first groove sidewall and a second groove sidewall arranged relatively along the first horizontal direction, and a third groove sidewall and a fourth groove sidewall arranged relatively along the second horizontal direction, and the first horizontal direction and the second horizontal direction are arranged vertically, and correspondingly, the sidewall of the sofa base 2 includes a first sidewall and a second sidewall arranged relatively along the first horizontal direction, and a third sidewall and a fourth sidewall arranged relatively along the second horizontal direction.

[0044] At least one pair of third electromagnets 321 are provided on oppositely arranged groove side walls, and at least one pair of fourth electromagnets 322 are provided on oppositely arranged side walls corresponding to the third electromagnets 321. In a possible implementation, the third electromagnet 321 is provided on the first groove side wall and the second groove side wall, and the fourth electromagnet 322 is provided on the first side wall and the second side wall. In this way, under the action of the third electromagnet 321 and the fourth electromagnet 322, the sofa body 1 can be kept stable in at least one horizontal direction.

[0045] In order to make the sofa body 1 more stable, the third electromagnet 321 is also arranged on the third groove side wall and the fourth groove side wall, and the fourth electromagnet 322 is also arranged on the third side wall and the fourth side wall. In this way, the sofa body 1 maintains a stable effect in two horizontal directions perpendicular to each other, so that the sofa body 1 has better stability, and people can experience more comfort after sitting on the sofa or when they need to adjust the suspension height.

[0046] In this embodiment, the groove 11 at the bottom of the sofa body 1 is a square groove, and the four groove side walls of the square groove constitute the first groove side wall, the second groove side wall, the third groove side wall and the fourth groove side wall. Correspondingly, the sofa base 2 is a square base, and the four side walls of the sofa base 2 constitute the first side wall, the second side wall, the third side wall and the fourth side wall.

[0047] It should be explained that in the diagram of the present embodiment, only the relatively arranged magnetic poles are shown, and the other magnetic pole is not shown. Specifically, the first electromagnet 311 and the second electromagnet 312 are arranged with S poles relatively, and the third electromagnet 321 and the fourth electromagnet 322 are arranged with N poles relatively. Of course, the first electromagnet 311 and the second electromagnet 312 can also be set to be arranged with N poles relatively, and the third electromagnet 321 and the fourth electromagnet 322 can be set to be arranged with S poles relatively, or the first electromagnet 311, the second electromagnet 312, the third electromagnet 321 and the fourth electromagnet 322 are all arranged with S poles relatively, or the first electromagnet 311, the second electromagnet 312, the third electromagnet 321 and the fourth electromagnet 322 are all arranged with N poles relatively, which is not limited here, so that the first electromagnet 311 and the second electromagnet 312 are arranged with the same poles relatively, and the third electromagnet 321 and the fourth electromagnet 322 are arranged with the same poles relatively.

[0048] The sofa base 2 can be in direct contact with the ground. Of course, a chassis 21 can also be provided at the bottom of the sofa base 2, so that the sofa base 2 is supported by the chassis 21. Specifically, the outer circumferential dimension of the chassis 21 is set to be larger than the notch dimension of the groove 11 of the sofa body 1, which can provide good support and stability for the sofa base 2. However, in order to prevent people's feet from touching the chassis 21 when sitting on the sofa, thereby causing danger or a bad experience, the outer circumferential dimension of the chassis 21 is set to be smaller than the outer circumferential dimension of the bottom of the sofa body 1. The sofa base 2 and the chassis 21 are both in the inner space at the bottom of the sofa body 1, which does not hinder the experience of people sitting on the sofa and has higher safety performance.

[0049] When the sofa body 1 is free of magnetic force, when the distance b between the bottom of the sofa body 1 and the top of the chassis 21 in the vertical direction is not less than the distance a between the first electromagnet 311 and the second electromagnet 312 in the vertical direction, a first anti-collision component is provided between the bottom wall of the groove 11 of the sofa body 1 and the top of the sofa base 2, and a second anti-collision component is provided between the side wall of the groove of the sofa body 1 and the side wall of the sofa base 2, so that the sofa body 1 can play a buffering role when colliding with the sofa base 2 in the horizontal direction and the sofa body 1 can play a buffering role when colliding with the sofa base 2 in the vertical direction. When the sofa body 1 touches the sofa base 2 when a human body sits on the sofa suddenly without the action of magnetic force, no large collision will occur, and the first magnet component 31 and the second magnet component 32 can play a protective role.

[0050] When the distance b between the bottom of the sofa body 1 and the top of the chassis 21 in the vertical direction is smaller than the distance a between the first electromagnet 311 and the second electromagnet 312 in the vertical direction, the sofa body 1 can always be in a suspended state. Therefore, a second anti-collision component can be provided only between the groove side wall of the sofa body 1 and the side wall of the sofa base 2, so that the sofa body 1 can play a buffering role when colliding with the sofa base 2 in the horizontal direction, and the sofa and the second magnet component 32 are protected. At this time, when a person sits on the sofa, he will not be greatly impacted.

[0051] Specifically, when the electromagnet is mounted on the groove side walls of the sofa body 1 and the side walls of the sofa base 2 in an embedded manner, if the anti-collision component is mounted on the groove side walls of the sofa body 1 and the side walls of the sofa base 2, the thickness of the anti-collision component can be smaller, but when the electromagnet is mounted on the groove side walls of the sofa body 1 and the side walls of the sofa base 2 in a manner of protruding from the groove side walls and the side walls, the thickness of the anti-collision component can be set to be greater than the thickness of the electromagnet, or the anti-collision component can be directly mounted on the electromagnet.

[0052] The anti-collision component can be implemented in a variety of ways, for example, sponge, elastic pad, etc. In this embodiment, the first anti-collision component and the second anti-collision component include an anti-collision rubber pad 5, which is easy to fit, has good elasticity, and is also easy to replace.

[0053] The chassis 21 can be a square chassis 21 or a conical chassis 21. In this embodiment, the chassis 21 adopts a conical chassis 21, which makes the chassis 21 more stable, thereby making the sofa base 2 more stable. When the sofa body 1 needs support from the chassis 21, it can also play a better supporting and stabilizing effect.

[0054] The second electromagnet 312 is laid along the top of the sofa base 2, and the size of the second electromagnet 312 is slightly smaller than the size of the top of the sofa base 2. Correspondingly, the first electromagnet 311 is arranged on the bottom wall of the groove 11 at the bottom of the sofa body 1 opposite to the second electromagnet, and the first electromagnet 311 has the same size as the second electromagnet.

[0055] The bottom wall of the groove 11 at the bottom of the sofa body 1 is arranged as close to the outer peripheral surface of the sofa body 1 as possible while ensuring the structural strength of the sofa, so that the groove 11 at the bottom of the sofa body 1 has sufficient space, so that the size range of the electromagnet arranged between the sofa base 2 and the groove 11 is larger, the size of the electromagnetic force has a larger adjustment range, and the area of ​​uniform magnetic force distribution is also larger, and the suspension height control selectivity is higher.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
