Description

Technical Field

[0001] This utility model relates to the field of furniture, specifically an electric sofa with adjustable posture. Background Technology

[0002] As people's living standards improve, their functional needs for sofas are increasing. Traditional sofas have a relatively fixed posture, which cannot meet people's diverse requirements for sofa posture in different scenarios such as rest and entertainment. For example, when watching TV, people may want the sofa back to recline appropriately to provide better leg support; when resting, they may need to adjust the sofa to a reclining position.

[0003] However, modern sofas are often fixed and do not have the function of adjusting posture.

[0004] Therefore, developing an adjustable electric sofa to meet different user needs is of great practical significance. Utility Model Content

[0005] The purpose of this invention is to provide an electric sofa with adjustable posture. By designing specific posture adjustment components, the sofa can be adjusted to various postures to meet the user's needs in different scenarios.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable electric sofa includes a seat, armrests, and a backrest. Two armrests are located on either side of the seat, and the backrest is located at the top rear of the seat. A posture adjustment mechanism is located beneath the seat.

[0008] The attitude adjustment component includes a fixed frame structure and a movable frame structure, which are connected by a rear link structure and a front link structure.

[0009] The fixed frame structure includes a rear frame, and side frames are fixedly connected to both ends of the rear frame.

[0010] The movable frame structure is located above the fixed frame structure and includes an upper movable frame.

[0011] The rear linkage structure includes a first rear linkage rotatably connected to the upper movable frame and a second rear linkage rotatably connected to the side frame, with the free ends of the first and second rear linkages rotatably connected.

[0012] The front linkage structure includes a front displacement rod, a first front support rod that is rotatably connected to the side frame, and a second front support rod that is rotatably connected to the upper moving frame.

[0013] A steering shift rod is provided between the two side frames, and a front connecting rod is rotatably connected to the steering shift rod and the front shift rod. A shaped connecting rod is fixedly connected to one end of the steering shift rod, and a leg support rod is rotatably connected to the other end of the shaped connecting rod. A support plate assembly is fixedly connected to the leg support rod. The steering shift rod is connected to a drive component.

[0014] As a further improvement of this utility model, a following link is rotatably connected between the leg support rod and the upper movable frame. The following link helps to make the movement of the leg support rod and the upper movable frame more coordinated during posture adjustment, ensuring the stability of the sofa posture adjustment.

[0015] The driving component includes a telescopic rod fixedly mounted on the rear frame. A steering connector is coaxially fixedly connected to the external part of the steering displacement rod, and the steering connector is rotatably connected to the telescopic end of the telescopic rod. The telescopic rod's extension and retraction movement causes the steering displacement rod to rotate first. When the steering displacement rod rotates to its limit, the telescopic rod drives the steering displacement rod to move, thereby realizing the movement of the entire posture adjustment assembly, causing the sofa seat to move, the backrest to rotate, and the leg rest to rotate, ultimately achieving the purpose of adjusting the sofa's posture.

[0016] The telescopic rod is a cylinder, which has the advantages of fast response and stable power output. It can efficiently drive the steering and shifting rod to achieve rapid adjustment of the sofa's posture.

[0017] An internal fixing plate is fixedly installed on the inside of the armrest seat, and the side frame is fixedly connected to the internal fixing plate. This connection method enhances the stability between the armrest seat and the posture adjustment components, making the entire sofa more sturdy and reliable during use.

[0018] The backrest is fixedly connected to the first rear link. When the posture adjustment component is activated, the first rear link drives the backrest to move, thereby adjusting the angle of the backrest and providing comfortable back support for the user.

[0019] This utility model has the following advantages: by setting a posture adjustment component, the posture of the sofa can be adjusted. When the drive component drives the steering displacement rod to rotate, through the linkage between the rear linkage structure, the front linkage structure and various components, the backrest of the sofa can tilt backward, the sofa seat can move outward, the leg support rod can rise, and the support plate assembly can unfold, providing users with a comfortable reclining posture and meeting the usage needs in different scenarios.

[0026] Please see Figure 1-3 An adjustable electric sofa includes a sofa seat 1, armrest seats 2, and a backrest 3. There are two armrest seats 2, which are respectively located on both sides of the sofa seat 1. The backrest 3 is located at the top rear side of the sofa seat 1. A posture adjustment component is provided below the sofa seat 1.

[0027] The attitude adjustment component includes a fixed frame structure and a movable frame structure, and a rear link structure and a front link 15 connect the fixed frame structure and the movable frame structure.

[0028] The fixed frame structure includes a rear frame 6, and side frames 7 are fixedly connected to both ends of the rear frame 6.

[0029] An internal fixing plate 5 is fixedly provided on the inner side of the armrest seat 2, and the side frame 7 is fixedly connected to the internal fixing plate 5.

[0030] The movable frame structure is located above the fixed frame structure, and the movable frame structure includes an upper movable frame 8;

[0031] The rear linkage structure includes a first rear linkage 10 rotatably connected to the upper movable frame 8, and a second rear linkage 11 rotatably connected to the side frame 7. The free ends of the first rear linkage 10 and the second rear linkage 11 are rotatably connected.

[0032] The backrest component 3 is fixedly connected to the first rear connecting rod 10.

[0033] The front connecting rod 15 structure includes a front displacement rod 14, a first front support rod 12 rotatably connected between the front displacement rod 14 and the side frame 7, and a second front support rod 13 rotatably connected between the front displacement rod 14 and the upper moving frame 8.

[0034] A steering shift rod 19 is provided between the two side frames 7. A front connecting rod 15 is rotatably connected between the steering shift rod 19 and the front shift rod 14. A special-shaped connecting rod 16 is fixedly connected to the end of the steering shift rod 19. A leg support rod 17 is rotatably connected to the other end of the special-shaped connecting rod 16. A following connecting rod 18 is rotatably connected between the leg support rod 17 and the upper moving frame 8. A support plate assembly 4 is fixedly connected to the leg support rod 17.

A steering connector 20 is coaxially fixedly connected to the outside of the steering shift rod 19, and the steering connector 20 is rotatably connected to the telescopic end of the telescopic rod 9.

[0036] The telescopic rod 9 is preferably a cylinder.

[0037] In the implementation of this utility model, when the sofa posture needs to be adjusted, the cylinder is activated, the cylinder extension rod 9 extends, driving the steering connector 20 to rotate, which in turn causes the steering displacement rod 19 to rotate. The rotation of the steering displacement rod 19 drives the front displacement rod 14 to move via the front connecting rod 15. At the same time, the steering displacement rod 19 drives the leg support rod 17 to move via the irregular connecting rod 16. The leg support rod 17 rotates and rises, and the support plate assembly 4 unfolds accordingly.

[0038] Then, when the steering shift rod 19 rotates to its limit position, the cylinder drives the steering shift rod 19 to move forward. At this time, the steering shift rod 19 drives the front shift rod 14 to move through the front connecting rod 15. The movement of the front shift rod 14 drives the upper moving frame 8 to move above the fixed frame structure through the first front support rod 12 and the second front support rod 13, thereby realizing the translation of the sofa seat 1.

[0039] The displacement of the upper movable frame 8 is transmitted through the first rear connecting rod 10 and the second rear connecting rod 11, causing the backrest component 3 to change angle. During this process, the following connecting rod 18 between the leg support rod 17 and the upper movable frame 8 ensures the coordination of their movements. By controlling the extension and retraction of the cylinder telescopic rod 9, precise adjustments to the sofa's posture can be achieved, meeting the user's needs in different scenarios such as rest and entertainment.
