Description

Technical Field

[0001] This application relates to the field of furniture technology, and in particular to a rotatable furniture. Background Technology

[0002] As living standards improve, users have more diverse needs for their home environment. As a result, they often need to move furniture to adjust the layout of their home. In some special public places (such as exhibition halls or conference rooms), it is necessary to move large furniture items relatively frequently according to the number of people and the needs of the scene. However, since most furniture cannot be moved or rotated easily, users cannot freely change the position and direction of the furniture, which affects the user experience. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a rotatable furniture that facilitates the rotation and movement of the furniture, thereby improving the user experience.

[0004] The rotatable furniture according to embodiments of this application includes:

[0005] The furniture body is supported on the ground;

[0006] The support base includes a first base, a second base, and a lifting mechanism. The first base is supported on the ground, the second base is connected to the furniture body, one end of the lifting mechanism is connected to the first base, and the other end of the lifting mechanism is rotatably connected to the second base. The lifting mechanism can move up and down along the height direction of the furniture body. The lifting mechanism is used to drive the furniture body to move away from the ground so that the furniture body can rotate relative to the first base.

[0007] The rotatable furniture according to the embodiments of this application has at least the following beneficial effects: by setting a first base with a support base to support the ground, a second base connected to the furniture body, one end of the lifting mechanism connected to the first base, and the other end of the lifting mechanism rotatably connected to the second base, the distance between the second base and the ground can be adjusted when the lifting mechanism moves up and down along the height direction of the furniture body. The lifting mechanism drives the furniture body to move away from the ground, so that the furniture body leaves the ground or the pressure of the furniture body on the ground is reduced, thereby reducing the resistance of the furniture body to rotate relative to the ground, so as to facilitate the rotation of the furniture body and improve the user experience.

[0008] According to some embodiments of this application, the lifting mechanism includes a support rod, a rotating shaft, and a foot-operated lifting module. The support rod is connected to the side of the first chassis near the second chassis. The rotating shaft is rotatably connected to the second chassis. The foot-operated lifting module is connected to the rotating shaft. The foot-operated lifting module is used to drive the rotating shaft to move away from or towards the support rod when stepped on.

[0009] According to some embodiments of this application, the foot pedal lifting module includes a foot pedal, a pawl, a drive wheel, a driven wheel, and a first rotating shaft. One end of the first rotating shaft is fixedly connected to the support rod, and the other end of the first rotating shaft is movably inserted through the drive wheel and the foot pedal. One end of the pawl is connected to the foot pedal, and the other end of the pawl extends into the tooth gap of the drive wheel. The pawl is used to drive the drive wheel to rotate under the action of the foot pedal. The driven wheel is meshed with the drive wheel and is perpendicular to the axis of the drive wheel. The driven wheel is rotatably connected to the support rod. A threaded hole is provided through the center of the driven wheel. The rotating shaft is provided with an external thread.

The stepping part is rotatably connected to the first rotating shaft, one end of the connecting part is fixedly connected to the stepping part, and the other end of the connecting part is hinged to the claw.

[0011] According to some embodiments of this application, the driving wheel includes a bidirectional ratchet and a rotating gear, the pawl is a bidirectional ratchet pawl, and the end of the pawl away from the foot pedal extends into the tooth gap of the bidirectional ratchet. The pawl is used to cooperate with the bidirectional ratchet so that the pawl moves in a first direction to engage with the bidirectional ratchet and drive the bidirectional ratchet to rotate. When the pawl moves in the opposite direction, it moves relative to the bidirectional ratchet. The foot pedal is rotatable relative to the first rotating shaft, which passes through the bidirectional ratchet and the rotating gear and is fixedly connected to the bidirectional ratchet and the rotating gear. The rotating gear meshes with the driven wheel, wherein the first direction is a clockwise direction or a counterclockwise direction.

[0033] As more and more users have diversified needs for home layout, their need for easy furniture movement is becoming increasingly urgent. Since most furniture cannot be moved or rotated easily, users cannot freely change the position and orientation of the furniture, which seriously affects the user experience.

[0034] Based on this, this application provides a rotatable furniture that reduces the resistance to rotation of the furniture relative to the ground by raising the furniture, thereby facilitating the rotation of the furniture and solving the problem of the user experience being affected by the inability of the furniture to move or rotate.

[0035] The contents of this application are described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that the following description is merely illustrative and not a specific limitation of this application.

[0036] Please refer to the following: Figure 1 and Figure 2 This application provides a rotatable furniture 1, including a furniture body 11 and a support base 12. The furniture body 11 is supported on the ground. The support base 12 includes a first base 121, a second base 122, and a lifting mechanism 123. The first base 121 is supported on the ground, and the second base 122 is connected to the furniture body 11. One end of the lifting mechanism 123 is connected to the first base 121, and the other end of the lifting mechanism 123 is rotatably connected to the second base 122. The lifting mechanism 123 can move up and down along the height direction of the furniture body 11. The lifting mechanism 123 is used to drive the furniture body 11 to move away from the ground so that the furniture body 11 can rotate relative to the first base 121.

[0037] The rotatable furniture 1 of this application embodiment is supported on the ground by a first base 121 with a support base 12, and a second base 122 connected to the furniture body 11. One end of the lifting mechanism 123 is connected to the first base 121, and the other end of the lifting mechanism 123 is rotatably connected to the second base 122. When the lifting mechanism 123 moves up and down along the height direction of the furniture body 11, it can adjust the distance between the second base 122 and the ground. The lifting mechanism 123 drives the furniture body 11 to move away from the ground, so that the furniture body 11 leaves the ground or the pressure of the furniture body 11 on the ground is reduced. This reduces the resistance of the furniture body 11 to rotation relative to the ground, making it easier to rotate the furniture body 11 and improving the user experience.

[0038] Optionally, the furniture body 11 includes, but is not limited to, any one of a sofa, storage cabinet, wardrobe, TV cabinet, etc. In this embodiment, the furniture body 11 is a straight sofa as an example for illustration.

[0039] Please combine Figures 3 to 4 In some embodiments, the rotatable furniture 1 further includes a support member 13, which is connected to the bottom of the furniture body 11. There are multiple support members 13, which are spaced apart.

[0040] In this way, by supporting the ground with the support component 13, compared with the furniture body 11 being directly supported on the ground, the contact area between the rotatable furniture 1 and the ground can be reduced, which helps to reduce the friction of the furniture body 11 rotating relative to the ground. At the same time, by supporting the ground with the support component 13, the position of the rotatable furniture 1 relative to the ground can be more stable during use, which helps to improve the user experience of the rotatable furniture 1.

[0041] Optionally, the support component 13 is a caster wheel.

[0042] In this way, by using casters as the support component 13 of the furniture body 11, the furniture body 11 can be rotated even when the lifting height of the lifting mechanism 123 is relatively small. This allows the user to rotate the furniture body 11 with less force, thereby improving the ease of rotation of the furniture body 11 and further enhancing the user's experience.

[0043] For example, when the furniture body 11 is raised to a relatively low height, just enough to transfer some of the pressure on the casters to the support base 12, the pressure of the casters on the ground decreases while maintaining contact with the ground. This reduces the rolling resistance of the casters relative to the ground. Simultaneously, by utilizing the low friction of the casters relative to the ground, the user can rotate the furniture body 11 with less force to achieve the desired rotational movement. Since the furniture body 11 is raised relatively low, the lifting mechanism 123 needs to be raised to a lower height. This reduces the driving force required for the lifting mechanism 123 to raise, saving energy. For example, when using a foot-operated lifting mechanism 123, it reduces the stepping force required to raise the mechanism, achieving a labor-saving effect. Furthermore, it improves the efficiency of furniture rotation, enabling rapid rotation and saving time.

[0044] In addition, using casters as support components 13 facilitates the horizontal movement of furniture, making it easier to move and adjust its position. This allows users to freely change the position of the furniture, thereby improving the user experience.

[0045] Understandably, in other embodiments, the support member 13 may also be a support column or pulley, etc.

[0046] Please refer to Figure 3 and Figure 4 Optionally, the second base 122 is connected to the bottom of the furniture body 11, the height of the support component 13 is greater than the minimum height of the support base 12, and the first base 121 is suspended relative to the ground when the support component 13 is supported on the ground.

[0047] In this way, when the furniture needs to be moved, the furniture body 11 is supported on the ground by the support component 13, and the first base 121 is suspended relative to the ground (that is, there is a certain distance between the first base 121 and the ground) to reduce the contact area between the furniture and the ground, thereby reducing the resistance to the furniture moving forward or backward or left or right, which is conducive to the movement of the furniture, so that the user can freely change the position of the furniture and improve the user's experience.

[0048] Optionally, the support component 13 can be detachably connected to the furniture body 11, thereby facilitating the replacement and maintenance of the support component 13, which is beneficial for furniture replacement and maintenance and reduces furniture repair costs.

[0049] Optionally, the connection method between the support component 13 and the furniture body 11 can be any one of threaded connection, magnetic connection or snap-on connection, etc., which can be set according to actual needs and is not limited here.

[0050] Please combine Figures 1 to 6In some embodiments, the lifting mechanism 123 includes a support rod 1231, a rotating shaft 1232, and a foot-operated lifting module. The support rod 1231 is connected to the side of the first chassis 121 near the second chassis 122. The rotating shaft 1232 is rotatably connected to the second chassis 122. The foot-operated lifting module is connected to the rotating shaft 1232. The foot-operated lifting module is used to drive the rotating shaft 1232 to move away from or towards the support rod 1231 when it is stepped on.

[0051] In this way, the lifting mechanism 123 is raised by stepping on it, and the pressure of stepping can be converted into the power for the movement of the lifting mechanism 123. Since the strength of the human foot is much greater than that of the hand, the foot-operated lifting is easier and less strenuous than the hand-cranked lifting. At the same time, the foot-operated lifting is not limited by the location of the power source compared to the electric lifting method, which makes the furniture placement more flexible and saves electricity and reduces energy consumption.

[0052] Optionally, the rotating shaft 1232 is connected to the second chassis 122 via a bearing. For example, the inner ring of the bearing is connected to the rotating shaft 1232, and the outer ring of the bearing is connected to the second chassis 122. This allows the second chassis 122 to rotate relative to the rotating shaft 1232 when it drives the furniture body 11 to rotate relative to the first chassis 121. At this time, the lifting mechanism 123 remains stationary. The lifting mechanism 123 and the first chassis 121 jointly support the furniture body 11, making the rotation of the furniture body 11 more stable and reliable.

[0053] Understandably, in other embodiments, the rotating shaft 1232 and the second chassis 122 may also be rotatably connected by means of shaft hole connection or roller connection.

[0054] Optionally, the foot pedal lifting module includes a foot pedal 1233, a pawl 1234, a drive wheel 1235, a driven wheel 1236, and a first rotating shaft. One end of the first rotating shaft is fixedly connected to the support rod 1231, and the other end of the first rotating shaft is movably inserted through the drive wheel 1235 and the foot pedal 1233. One end of the pawl 1234 is connected to the foot pedal 1233, and the other end of the pawl 1234 extends into the tooth gap of the drive wheel 1235. The pawl 1234 is used to drive the drive wheel 1235 to rotate under the action of the foot pedal 1233. The driven wheel 1236 is meshed with the driving wheel 1235. The driven wheel 1236 is perpendicular to the axis of the driving wheel 1235. The driven wheel 1236 is rotatably connected to the support rod 1231. A threaded hole is provided through the center of the driven wheel 1236. The rotating shaft 1232 is provided with external thread. The support rod 1231 is provided with a hollow part. The rotating shaft 1232 is threaded to the threaded hole and extends into the hollow part. The driven wheel 1236 is used to rotate under the drive of the driving wheel 1235 to drive the rotating shaft 1232 to move along the height direction of the furniture body 11.

[0055] In this way, by stepping on or raising the foot pedal 1233, the foot pedal 1233 causes the pawl 1234 to swing relative to the first rotating shaft. The pawl 1234 drives the drive wheel 1235 to rotate, and the drive wheel 1235 drives the driven wheel 1236 to rotate. Since the driven wheel 1236 is rotatably connected to the support rod 1231, the position of the driven wheel 1236 in the height direction of the furniture body 11 remains fixed, so that the internal thread of the driven wheel 1236 drives the rotating shaft 1232 to move along the height direction of the furniture body 11, thereby causing the furniture body 11 to rise or fall.

[0056] Understandably, in other embodiments, the first rotating shaft may also be rotatably connected at one end to the support rod and fixedly connected at the other end to the drive shaft, and rotatably connected to the foot pedal; or, the first rotating shaft may be rotatably connected to the support rod, the drive wheel and the foot pedal respectively.

[0057] Please combine Figure 7 Optionally, the foot pedal 1233 includes a pedal portion 12331 and a connecting portion 12332. The pedal portion 12331 is connected to the first rotating shaft, one end of the connecting portion 12332 is fixedly connected to the pedal portion 12331, and the other end of the connecting portion 12332 is hinged to the pawl 1234. This allows the pawl 1234 to move more flexibly relative to the drive wheel 1235, which helps to make the structure of the foot pedal lifting module more reliable and avoids structural jamming.

[0058] Optionally, considering that in some cases, when the connecting part 12332 extends towards the ground, the pawl 1234 may disengage from the backlash of the drive wheel 1235 under its own weight, causing the pawl 1234 to be unable to drive the drive wheel 1235 to rotate, thus affecting the lifting control of the lifting mechanism 123, the extending direction of the pedal part 12331 is set at an angle to the extending direction of the connecting part 12332, and the connecting part 12332 extends away from the ground. This helps to ensure that the pawl 1234 is located in the backlash of the gear, thereby improving the structural reliability of the foot pedal lifting module.

[0059] In one embodiment, the driving wheel 1235 is engaged with the driven wheel 1236, and the end of the pawl 1234 away from the foot pedal 1233 is engaged in the tooth gap of the driving wheel 1235. During the lifting process of the lifting mechanism 123, the pawl 1234 remains in the same tooth gap. For example, see... Figures 3 to 6As shown, with the viewing angle perpendicular to the paper and pointing into the paper, when the foot pedal 1233 is pressed, the pawl 1234 drives the drive wheel 1235 to rotate clockwise around the axis of the first rotating shaft. The drive wheel 1235 drives the driven wheel 1236 to rotate counterclockwise around the axis of the rotating shaft 1232. The external thread of the rotating shaft 1232 meshes with the internal thread of the driven wheel 1236. Driven by the rotation of the driven wheel 1236, the rotating shaft 1232 moves upward along the height direction of the furniture body 11 (i.e., away from the support rod 1231), thereby driving the second base 122 to move away from the first base 121, thus raising the furniture body 11. When the furniture body 11 is raised until the support member 13 leaves the ground or the pressure of the support member 13 on the ground decreases, the furniture body 11 can be manually pushed to rotate around the axis 1232. The furniture body 11 rotates around its axis to change its orientation and move. When the foot pedal 1233 is lifted, the pawl 1234 drives the drive wheel 1235 to rotate counterclockwise around the axis of the first shaft. The drive wheel 1235 drives the driven wheel 1236 to rotate clockwise around the axis of the rotating shaft 1232. The external thread of the rotating shaft 1232 engages with the internal thread of the driven wheel 1236. Driven by the rotation of the driven wheel 1236, the rotating shaft 1232 moves downward along the height direction of the furniture body 11 (i.e., towards the support rod 1231) to drive the second base 122 to move towards the first base 121, thereby causing the furniture body 11 to descend. When the furniture body 11 descends to the point where the support member 13 supports the ground, the position of the furniture body 11 relative to the ground becomes more stable, allowing the furniture body 11 to switch to the use state.

[0060] In another embodiment, the drive wheel 1235 includes a bidirectional ratchet and a rotating gear. The pawl 1234 is a bidirectional ratchet pawl, with one end of the pawl 1234 away from the foot pedal 1233 extending into the tooth gap of the bidirectional ratchet. The pawl 1234 is used to engage with the bidirectional ratchet so that the pawl 1234 moves in a first direction to engage with the bidirectional ratchet and drive the bidirectional ratchet to rotate. When the pawl 1234 moves in the opposite direction, it moves relative to the bidirectional ratchet. The foot pedal 1233 is rotatable relative to a first rotating shaft, which passes through and is fixedly connected to the bidirectional ratchet and the rotating gear. The rotating gear meshes with the driven wheel 1236. The first direction is clockwise, and the opposite direction is counterclockwise, or the first direction is counterclockwise and the opposite direction is clockwise.

[0061] In this way, by using the driving direction of the bidirectional ratchet and the bidirectional pawl, the unidirectional rotation of the bidirectional ratchet can be realized, so that the lifting mechanism 123 can increase the lifting distance by repeatedly lifting and pressing the foot pedal 1233, thereby increasing the lifting distance of the furniture body 11. At the same time, by adjusting the engagement position of the bidirectional pawl and the bidirectional ratchet, the unidirectional rotation direction of the bidirectional ratchet can be changed, thereby changing the movement direction of the rotating shaft 1232 when the foot pedal 1233 is pressed.

[0062] For example, when the bidirectional ratchet rotates counterclockwise around the axis of the first rotating shaft, the teeth of the bidirectional ratchet abut against the pawl 1234. At this time, by pressing the foot pedal 1233, the pawl 1234 drives the bidirectional ratchet to rotate clockwise around the axis of the first rotating shaft. The bidirectional ratchet drives the rotating gear to rotate clockwise through the first rotating shaft. Since the rotating gear is meshed with the driven wheel 1236, the driven wheel 1236 rotates counterclockwise around the axis of the rotating shaft 1232 under the drive of the rotating gear. The external thread of the rotating shaft 1232 meshes with the internal thread of the driven wheel 1236. Driven by the rotation of the driven wheel 1236, the rotating shaft 1232 moves upward along the height direction of the furniture body 11 (i.e., away from the support rod 1231) to drive... The second chassis 122 moves away from the first chassis 121, thereby raising the furniture body 11. To raise the furniture body 11 to a greater height, the steps of lifting the foot pedal 1233 and pressing it down again can be repeated. Since the bidirectional ratchet has the characteristic of unidirectional rotation, when the foot pedal 1233 is lifted, the pawl 1234 can swing counterclockwise along the outer circumference of the teeth of the bidirectional ratchet, so that the pawl 1234 moves relative to the bidirectional ratchet. That is, at this time, the counterclockwise swing of the pawl 1234 will not drive the bidirectional ratchet to rotate. When the foot pedal 1233 is pressed down again, the pawl 1234 can engage in the teeth of the bidirectional ratchet, so that the bidirectional ratchet can rotate clockwise around the axis of the first rotating shaft, thereby raising the furniture body 11.

[0063] When it is necessary to lower the furniture body 11, firstly, by adjusting the position of the pawl 1234 relative to the foot pedal 1233, the teeth of the bidirectional ratchet abut against the pawl 1234 when the bidirectional ratchet rotates clockwise around the axis of the first rotating shaft, thereby changing the unidirectional rotation direction of the bidirectional ratchet. At this time, by lifting the foot pedal 1233 upward, the pawl 1234 drives the bidirectional ratchet to rotate counterclockwise around the axis of the first rotating shaft. The bidirectional ratchet drives the rotating gear to rotate counterclockwise through the first rotating shaft. Since the rotating gear is meshed with the driven wheel 1236, the driven wheel 1236 rotates clockwise around the axis of the rotating shaft 1232 under the drive of the rotating gear. The external thread of the rotating shaft 1232 meshes with the internal thread of the driven wheel 1236. Driven by the rotation of the driven wheel 1236, the rotating shaft 1232 moves along the height direction of the furniture body 11. The foot pedal 1233 moves downward (i.e., towards the support rod 1231) to drive the second chassis 122 towards the first chassis 121, thereby causing the furniture body 11 to descend. When the foot pedal 1233 is pressed down again, the pawl 1234 can swing clockwise along the outer circumference of the teeth of the bidirectional ratchet, so that the pawl 1234 moves relative to the bidirectional ratchet. That is, at this time, the clockwise swing of the pawl 1234 will not drive the bidirectional ratchet to rotate. When the foot pedal 1233 is lifted again, the pawl 1234 can engage in the teeth of the bidirectional ratchet, so that the bidirectional ratchet rotates counterclockwise around the axis of the first rotating shaft, thereby causing the furniture body 11 to descend. Repeating the steps of lifting and lowering the foot pedal 1233 allows the furniture body 11 to descend until the support member 13 touches the ground, so that the furniture body 11 remains stable relative to the ground.

[0064] It should be noted that the bidirectional ratchet mechanism (i.e., the combination of a bidirectional ratchet and a bidirectional pawl) is a well-known, mature, and commercialized technology in the machinery industry, such as the bidirectional ratchet wrench commonly found on assembly lines, so it will not be elaborated upon further.

[0065] Please combine Figure 3 and Figure 7 In some embodiments, considering that the foot pedal 1233 is not needed when the furniture is in use, and that the foot pedal 1233 is located at the bottom of the furniture body 11 and is easily accidentally touched, causing changes in the height of the furniture body 11 and affecting the structural stability of the furniture, the foot pedal 12331 is extendable along its own length. This allows the foot pedal 12331 to be shortened when in use, concealing it at the bottom of the furniture body 11, thus preventing accidental touches. When the foot pedal 12331 is needed, it can be extended to extend beyond the furniture body 11, facilitating the user to step on or lift the foot pedal 12331, thereby adjusting the height of the lifting mechanism 123.

[0066] Optionally, the foot pedal 12331 can be a telescopic rod, and the foot pedal 12331 includes multiple telescopic joints that are connected together. Adjacent telescopic joints are directly positioned by a buckle, which helps to keep the length of the foot pedal 12331 stable.

[0067] Understandably, in other embodiments, the foot pedal 12331 may also be a sliding rod telescopic mechanism or a scissor telescopic mechanism, etc.

[0068] It should be noted that the rotation angle of the furniture body 11 can be 0°-360°, such as 45°, 90°, 180°, 270° or 360°. When the rotation angle of the furniture body 11 is large (for example, the rotation angle is 180°), and the support member 13 needs to rotate over the foot pedal 12331, the furniture body 11 should be raised before rotation so that the bottom of the support member 13 is higher than the foot pedal 12331. That is, after the furniture body 11 is raised, the distance from the support member 13 to the ground should be greater than the thickness of the foot pedal 12331 along the height direction of the furniture body 11. In other words, after the furniture body 11 is raised, the distance from the bottom of the support member 13 to the ground should be greater than the distance from the top of the foot pedal 12331 to the ground. This can satisfy the free rotation of the furniture body 11 and improve the reliability of the rotation of the furniture body 11. When the rotation angle of the furniture body 11 is small (e.g., less than 90°), and the support component 13 does not need to go over the footrest 12331, the height of the furniture body 11 only needs to be sufficient to allow the support component 13 to leave the ground, or to reduce the pressure of the support component 13 on the ground, thus achieving the effect of reducing the resistance of the furniture body 11 to rotation relative to the ground.

[0069] Please combine Figure 1 and Figure 3 In some embodiments, the support base 12 is located at the center of the furniture body 11. This allows the furniture body 11 to rotate more smoothly around the axis of the rotation shaft 1232, which helps ensure the structural stability of the furniture.

[0070] In other embodiments, considering that after furniture is placed in a fixed position for a period of time, a certain amount of dust will accumulate on the bottom of the furniture. Since the space between the bottom of the furniture and the base plate is small, it is not convenient to clean. Therefore, it is usually necessary to move the furniture to complete the cleaning. However, when the support base 12 is located at the center of the furniture body 11, the furniture body 11 only changes direction after rotation, but the projection of the furniture body 11 is still in the original position, and the problem of cleaning difficulty cannot be solved. Based on this, the support base 12 can be set near the edge of the furniture body 11 so that the projections of the furniture body 11 before and after rotation do not completely overlap, so as to facilitate cleaning the bottom of the furniture body 11.

[0071] It should be noted that in this embodiment, casters are used as support components 13, which can conveniently move the furniture body 11 left, right, forward and backward, so as to expose the garbage at the bottom of the furniture body 11, thereby facilitating cleaning the bottom of the furniture body 11.

[0072] Please refer to it again. Figure 2 In some embodiments, considering that the structure of the support base 12 is more prone to damage and has a shorter lifespan than the furniture body 11 when adjusting the height and rotation of the rotatable furniture 1, the second base 122 is detachably connected to the furniture body 11. This facilitates the maintenance and replacement of the support base 12, improves the convenience of maintenance of the support base 12, and helps reduce the maintenance cost of the rotatable furniture 1. When the components of the support base 12 are damaged, only the corresponding parts need to be replaced, without scrapping the entire furniture.

[0073] Optionally, the second chassis 122 is threadedly connected to the furniture body 11 by threaded fasteners, such as screws, which facilitates the installation and disassembly of the second chassis 122 and the furniture body 11, and ensures the reliability of the connection between the support base 12 and the furniture body 11.

[0074] Understandably, in other embodiments, the connection between the second chassis 122 and the furniture body 11 can also be a magnetic connection or a snap-fit ​​connection, etc.

[0075] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
