Description

Technical Field

[0001] This application relates to the field of home design technology, and in particular to a sofa seating adjustment device and a sofa with adjustable seating. Background Technology

[0002] Currently, sofa seat adjustment mainly relies on preset parameters of fixed elastic elements (such as serpentine springs and foam), preventing users from adjusting the firmness in real time. Some sofas adjust their seat feel by using built-in airbags to support the cushions. For example, users can adjust the airbag inflation level via a separate manual switch or control panel to increase support and change cushion firmness to accommodate different weights and usage needs. However, this method has several drawbacks: first, the inflation and deflation process is lengthy, limiting the response speed and precision of seat adjustment; second, the airbag system has many components and a complex structure, resulting in higher production and maintenance costs than traditional mechanical structures; third, it has poor long-term durability—repeated inflation and deflation can cause the airbag material to age and leak slowly, reducing support, and frequent pump starts may shorten its lifespan; furthermore, using airbags to adjust sofa seat feel can generate noise due to friction between the airbags and sofa components. Therefore, there is an urgent need for a sofa seat adjustment solution that is highly efficient, low-cost, and allows for precise control of seat feel to address the problems existing in current sofa seat adjustment technologies.

[0027] Example 1

[0028] One embodiment of this application provides a sofa seating adjustment device 100, which is installed on a sofa seat frame 200 and includes an elastic support member 110 and an adjustment assembly 120. The elastic support member 110 is used to provide elastic support for the sofa seating. The adjustment assembly 120 is installed below the elastic support member 110 and includes a support portion 121 fixed to the bottom of the sofa seat frame 200, and a telescopic member 122 and a lifting bracket 123 installed on the support portion 121. The free end of the telescopic member 122 is connected to one end of the lifting bracket 123, and the other end of the lifting bracket 123 is connected to a support plate 124. The telescopic member 122 adjusts the height of the lifting bracket 123 through telescopic movement so that the support plate 124 lifts or releases the elastic support member 110.

[0029] Specifically, such as Figure 2 As shown, the sofa frame 200 is divided into an upper frame 210 and a lower frame 220. The upper frame 210 is used to install serpentine springs—that is, elastic support members 110—and to place the seat cushion 400. The serpentine springs are distributed parallel to each other on the upper frame 210, bearing the weight when the user sits down, forming an elastic sitting feel to provide a comfortable experience. On the lower frame 220 below the serpentine springs, an adjustment component 120 is installed. The adjustment component 120 specifically consists of a support rod fixed to the lower frame 220 by screws, and a telescopic member 122, a lifting bracket 123, and a support plate 124 are installed on the support rod.

[0030] More specifically, the support rod is provided with a horizontally linear guide hole 1211, the telescopic component 122 is a hydraulic cylinder, fixed parallel to the support rod, and the lifting bracket 123 is a scissor structure, such as... Figure 3 , Figure 4The device shown includes a set of cross-links. One link in the cross-link set is axially connected to the piston rod / free end of the hydraulic cylinder, with the connecting shaft passing through a guide hole 1211. The other link is rotatably connected to a support rod. The two links are cross-linked and also axially connected at the middle position. When the piston rod extends, the angle between the axially connected link and the support rod (or horizontal plane) gradually decreases under the constraint of the guide hole 1211. Simultaneously, the rotation of the other link has the same effect, and the horizontal height of the other end of the two links gradually decreases. A support plate 124 is fixedly connected to the other end of the two links through a connector. The height of the support plate 124 decreases under the action of the links, releasing the support effect on the serpentine spring. The sofa seating adjustment device 100 controls the seating feel to change from firm to soft. Conversely, the angle between the link and the support rod (or horizontal plane) gradually increases, the horizontal height of the other end gradually increases, and the height of the support plate 124 rises under the action of the links, forming a support against the serpentine spring, and the seating feel becomes firmer.

[0031] It is understandable that multiple sets of cross linkages can be set to facilitate different height adjustment needs; it is also possible that the cross linkages can be set in parallel to increase the overall structural stability, in which the telescopic component 122 and the support rod should also be set to realize their functions.

[0032] In this embodiment, the serpentine spring and the adjusting component 120 work together to support or release the serpentine spring under the action of the telescopic component 122, the lifting bracket 123 and the support plate 124, thereby achieving the effect of adjusting the seating comfort to different degrees of softness and hardness. At the same time, the structure is simple, easy to assemble and low in cost.

[0033] Example 2

[0034] Combination Figures 2-4 The sofa frame 200 is divided into an upper frame 210 and a lower frame 220. The upper frame 210 is used to install the elastic support member 110 and place the seat cushion 400. Besides the serpentine spring used in the previous embodiment, the elastic support member 110 can also use ordinary springs, spring sheets, or other components with elastic support functions. The elastic support member 110 bears the weight when the user sits down, creating an elastic seating feel to provide a comfortable experience. An adjustment assembly 120 is installed on the lower frame 220. The adjustment assembly 120 specifically consists of a support rod or support frame fixed to the lower frame 220 by screws. A telescopic member 122, a lifting bracket 123, and a support plate 124 are installed on the support rod / frame.

[0035] More specifically, the support rod / frame is provided with a horizontally linear guide hole 1211, the telescopic component 122 is a hydraulic cylinder, fixed parallel to the support rod, and the lifting bracket 123 is a scissor structure. It should be noted that the telescopic component 122 and the lifting bracket 123 in this application are not limited to hydraulic cylinders and scissor structures. The telescopic component 122 can also use a pneumatic cylinder, motor, etc., to achieve the extension and retraction function of the free end, and the lifting bracket 123 can also use a crank-connecting rod mechanism or a screw drive mechanism to achieve linear reciprocating motion. For ease of understanding, this embodiment continues to use the structural diagram of the previous embodiment for explanation. Specific details will not be repeated. One end of the lifting bracket 123 is fixedly connected to a support plate 124, which moves up and down under the lifting action to achieve seat comfort adjustment.

[0036] Specifically, the shape and size of the support plate 124 are adapted to the shape and size of the elastic support member 110. For example, if the elastic support member 110 is arched, the cross-section of the support plate 124 is also arched to match it, forming complete support after lifting. Alternatively, if the area covered by the elastic support member 110 is 70% to 100% of the sofa cushion 400, the area of ​​the support plate 124 remains consistent. In particular, the support plate 124 includes a hard bottom and a soft top. The hard bottom is used for fixed connection with the lifting bracket 123 to enhance structural stability, while the soft top, which contacts the elastic support member 110, provides cushioning and extends service life.

[0037] Furthermore, the adjustment assembly 120 also includes a controller (not shown in the figure), which is communicatively connected to the telescopic member 122 and used to control the telescopic movement of the telescopic member 122. The controller can be a wired controller or a wireless controller, and can take the form of a remote control button, touch panel, etc. By controlling the telescopic movement of the telescopic member 122 (e.g., a motor), the support plate 124 is driven to move up and down, dynamically adjusting the rebound travel space of the elastic support member 110, facilitating the adjustment of the firmness of the sofa.

[0038] In this embodiment, by specifically designing the structure and material of the tray 124 and providing an additional dedicated control method for the sofa seating adjustment device 100 to facilitate use, the practicality of the device and the user experience can be improved.
