Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a sofa structure. Background Art

[0002] A sofa is a household product that people often use, mainly for relaxing the mind and relieving fatigue. Generally, it mainly includes a seat body, a backrest, a headrest, etc. Each of the above parts can be set separately or integrated. Thus, a resting posture of sitting or lying back can be achieved. To meet the different needs of users for the resting posture, some existing sofas are set to be able to rock back and forth to enhance the use experience. It usually relies on an arc-shaped guide rail in contact with the ground at the bottom to achieve back-and-forth swing. For example, the solutions disclosed in CN220141179U and CN209528506U. During the back-and-forth swing of this kind of sofa, the contact with the ground at the end position is very rigid, affecting the user experience. Moreover, the swing mode is too single, and it can only swing back and forth and cannot swing in the left and right directions, unable to meet more physical experience needs. Summary of the Utility Model

[0003] The utility model provides a sofa structure with multiple rocking postures and more comfortable experience to solve the above problems existing in the prior art.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

At least one set of front elastic support members is provided between the seat frame and the base, and at least one set of rear elastic support members is provided behind the front elastic support members between the seat frame and the base. In the natural state, the seat frame is in a balanced state under the action of the front elastic support members and the rear elastic support members. When a person sits on the seat frame and rocks, causing the overall center of gravity to change, the front elastic support members and the rear elastic support members are compressed and deformed, so that the seat frame adaptively generates elastic swing.

[0006] By adopting the above technical scheme, after a person sits on the seat frame, it is elastically supported by the front elastic support members and the rear elastic support members. When the person rocks the body, as the center of gravity changes, the front elastic support members and the rear elastic support members will adaptively deform, so that the person and the seat frame perform elastic swing and rock, and can swing in multiple directions to meet different physical experience needs, and the comfort is better.

[0007] Preferably, the front elastic support members are configured as two front springs, and the two front springs are respectively arranged on the left and right sides of the seat frame. The upper end of the front spring is fixedly connected to the seat frame, and the lower end of the front spring is fixedly connected to the base. The two front springs provide elastic support, and the overall stability is better.

[0008] Preferably, the rear elastic support is configured as two rear springs, which are respectively arranged on the left and right sides of the seat frame and behind the front spring. The two rear springs provide elastic support, ensuring good overall stability.

[0009] Preferably, the two groups of front springs are distributed in parallel, and the two groups of rear springs are also distributed in parallel; in the natural state, the axes of the two groups of front springs are perpendicular to the horizontal plane, and the axes of the two groups of rear springs are perpendicular to the horizontal plane. Being perpendicular to the horizontal plane provides better support effect.

[0010] Preferably, an upper connecting seat is fixedly provided on the seat frame, and a lower connecting seat corresponding to the upper connecting seat is fixedly provided on the base. The upper end of the front spring is connected to the front end of the upper connecting seat, the lower end of the front spring is connected to the front end of the lower connecting seat, the upper end of the rear spring is connected to the rear end of the upper connecting seat, and the lower end of the rear spring is connected to the rear end of the lower connecting seat.

[0011] Preferably, when a person sits naturally on the seat frame, the center of gravity of the person and the seat frame is located in the area between the front spring and the rear spring. The positions of the front spring and the rear spring are sufficient to ensure safety, that is, it is stable and reliable during the overall swaying process and will not tip over.

[0012] Preferably, a footrest is provided at the bottom of the front end of the seat frame, and a telescopic mechanism for driving the footrest to expand and contract is provided on the seat frame. By providing a telescopic footrest, the footresting needs can be met.

[0013] Preferably, the telescopic mechanism includes fixed arms fixedly provided on both sides of the seat frame, a telescopic bracket rotatably connected to the front ends of the fixed arms, a front cross bar arranged between the telescopic brackets, a rear cross bar arranged between the rear ends of the fixed arms, and a driving component arranged between the front cross bar and the rear cross bar.

[0014] Preferably, the telescopic bracket includes a front connecting arm, a rear connecting arm, an upper connecting arm, and a lower connecting arm. The upper end of the front connecting arm is rotatably connected to the fixed arm, the front cross beam is fixedly arranged between the front connecting arms, the upper end of the rear connecting arm is rotatably connected to the fixed arm, the rear end of the upper connecting arm is rotatably connected to the lower end of the rear connecting arm, the middle part of the upper connecting arm is rotatably connected to the front connecting arm, the rear end of the lower connecting arm is rotatably connected to the lower end of the front connecting arm, a foot plate seat is arranged between the front end of the upper connecting arm and the front end of the lower connecting arm, and both ends of the footrest are fixedly connected to the foot plate seat respectively. The driving component is configured as an electric push rod.

[0015] Therefore, the utility model has the beneficial effects of having multiple swaying postures and providing a more comfortable experience. BRIEF DESCRIPTION OF THE DRAWINGS
