[0037] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0039] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0040] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0041] The utility model provides an adjustable elastic support structure and furniture, which are suitable for use as a sofa or a bed to provide elastic support for a human body, and can solve the problem of insufficient support hardness of the existing elastic support structure after a long time.

[0042] See also Figure 1 The furniture includes a soft pad 100 and an adjustable elastic support structure 200 located below the soft pad 100. It should be noted that the furniture may be a sofa or a bed, which is not limited in the present invention.

[0043] See also Figure 2The adjustable elastic support structure 200 includes a bottom frame 1, an arc-shaped support member 2 whose first end abuts against the bottom frame 1, and an adjustment component 3 connected to the second end of the arc-shaped support member 2. The adjustment component 3 is used to drive the second end of the arc-shaped support member 2 to approach the first end.

[0044] The adjustable elastic support structure 200 provided in this embodiment has a relatively strong structural strength of the arc support member 2 at the beginning, and the distance between the two ends of the arc support member 2 can be appropriately increased to provide a more comfortable elastic support; after a long period of use, the arc support member 2 has a reduced structural strength due to aging, and at this time, the distance between the two ends of the arc support member 2 can be appropriately reduced by adjusting the component 3 (making the second end close to the first end) so as to increase the support hardness of the middle convex arch position of the arc support member 2, thereby compensating for the decrease in support hardness caused by aging, so that the arc support member 2 can still provide sufficient support, thereby solving the problem of insufficient support hardness of the existing elastic support structure after a long time;

[0045] In addition to being used to compensate for the decrease in support hardness caused by aging, the adjustable elastic support structure 200 can also be used as a hardness adjustment structure in daily use. Users can adjust the adjustable elastic support structure according to their own needs for support hardness, so that the adjustable elastic support structure 200 can meet the diverse support hardness requirements of the consumer market.

[0046] In this embodiment, the arc-shaped support member 2 includes a connecting transverse plate 201 abutting against the V-shaped abutment plate 301 and a plurality of arched arch plates 202 fixed on the connecting transverse plate 201, wherein the middle portion of each arched arch plate 202 is arched upward to provide support for the soft pad 100.

[0047] The bottom frame 1 is a rectangular frame structure as a whole, and surrounds a frame groove 101 for accommodating each of the arcuate arch plates 202. The bottom frame 1 is provided with a receiving cavity 102 communicating with the frame groove 101.

[0048] The adjustment assembly 3 is installed in the accommodating cavity 102 , the connecting transverse plate 201 is slidably disposed in the accommodating cavity 102 , and the end of each of the arched plates 202 away from the connecting transverse plate 201 abuts against the inner wall of the frame groove 101 .

[0049] Optionally, the inner wall of the frame groove 101 is provided with a positioning groove 103 for inserting the arch plate 202. Inserting the arch plate 202 into the positioning groove 103 can prevent the arch plate 202 from moving up and down, thereby ensuring reliability when adjusting the support hardness.

[0050] In this embodiment, the adjustment assembly 3 includes a V-shaped abutment plate 301 and a linear drive assembly 302 .

[0051] The V-shaped abutment plate 301 includes a first abutment plate 3011 and a second abutment plate 3012; wherein, the base frame 1 is fixedly provided with a first rotating shaft 104, one end of the first abutment plate 3011 is rotatably connected to the base frame 1 via the first rotating shaft 104, the connecting cross beam is fixedly provided with a second rotating shaft 203, one end of the second abutment plate 3012 is rotatably connected to the arc-shaped support member 2 via the second rotating shaft 203, and the other ends of the first abutment plate 3011 and the second abutment plate 3012 are rotatably connected via a third rotating shaft 3013.

[0052] The linear drive assembly 302 abuts against the connection position of the first abutment plate 3011 and the second abutment plate 3012, and is used to push the connection position of the first abutment plate 3011 and the second abutment plate 3012 to increase the angle between the first abutment plate 3011 and the second abutment plate 3012 (hereinafter referred to as "abutment angle").

[0053] In this embodiment, the linear drive assembly 302 includes a push plate 3021, a screw rod 3022, and a rotation drive mechanism 3023. The push plate 3021 is located on a side of the third rotating shaft 3013 away from the first abutment plate 3011 and the second abutment plate 3012, and is slidably connected to the bottom frame 1 along the length direction of the screw rod 3022; the screw rod 3022 is threadedly connected to the push plate 3021; ​​and the rotation drive mechanism 3023 is transmission-connected to the screw rod 3022.

[0054] Generally, under the elastic action of the arch plate 202, the abutment angle tends to gradually decrease until the third shaft 3013 abuts the push plate 3021. The abutment angle does not need to be further reduced, and the distance between the two ends of the arc support member 2 no longer changes. If the bow-shaped arch plate 202 has a problem of insufficient support hardness due to aging, the rotation drive mechanism 3023 can be started to drive the screw rod 3022 to rotate, thereby driving the push plate 3021 to move in the direction close to the rotation drive mechanism 3023. In this process, since the first rotating shaft 104 and the second rotating shaft 203 will not shift, the third rotating shaft 3013 will gradually approach the rotation drive mechanism 3023 under the thrust of the push plate 3021, and the abutment angle will gradually increase under the pushing action of the push plate 3021, thereby causing the connecting cross bar to slide relative to the bottom frame 1 toward the other end of the bow-shaped arch plate 202, and the distance between the two ends of the bow-shaped arch plate 202 is reduced, so the support hardness of the middle position of the bow-shaped arch plate 202 is improved.

[0055] Therefore, by controlling the rotation direction and number of rotations of the screw rod 3022 , the distance between the two ends of the arch plate 202 can be increased or decreased, thereby increasing or decreasing the support hardness of the arch plate 202 .

[0056] Optional, see Figure 3 The V-shaped abutment plate 301 is provided with a rod-passing slot 3014 for the screw rod 3022 to pass through. When the angle of the V-shaped abutment plate 301 changes, the screw rod 3022 always moves in the rod-passing slot 3014, thereby avoiding interference between the screw rod 3022 and the V-shaped abutment plate 301. Figure 2 The number of the V-shaped abutment plates 301 is two; the rotation drive mechanism 3023 is located between the two V-shaped abutment plates 301, and the two V-shaped abutment plates 301 are symmetrically arranged about the rotation drive mechanism 3023. Such a structural layout is conducive to improving the compactness of the structure and reducing space waste.

[0057] In summary, the adjustable elastic support structure 200 and the furniture provided in this embodiment have the following advantages:

[0058] ① By controlling the rotation direction and number of turns of the screw rod 3022, the distance between the two ends of the arch plate 202 can be increased or decreased, thereby increasing or decreasing the support hardness of the arch plate 202, thereby solving the problem of insufficient support hardness of the existing elastic support structure after a long time;

[0059] ② The adjustable elastic support structure 200 can also be used as a hardness adjustment structure in daily use. Users can adjust the adjustable elastic support structure according to their own needs for support hardness, so that the adjustable elastic support structure 200 can meet the diverse support hardness requirements of the consumer market.
