One end of the pull rod 60 is hinged to the front leg support bracket 321 through the support plate 43, and the other end of the pull rod 60 is hinged to the base 10 and the fixed bracket 20 through the support plate 43. Two pull rods 60 are provided, one on each opposite side of the furniture frame. When the drive mechanism 40 drives the rear leg support bracket 322 to rotate, the front leg support bracket 321 is driven to rotate through the pull rod 60 to adjust the leg support.

[0061] According to an embodiment of the present application, a reinforcing rib 61 is provided on the pull rod 60 along the length direction of the pull rod 60 , and the reinforcing rib 61 protrudes toward the outside of the pull rod 60 .

[0062] Multiple support rods 70 are positioned beneath the rotating bracket 30. These rods 70 include horizontal sections 71 flush with the base 10 and vertical sections 72 connected to the rotating bracket 30. Connecting tubes 73 are located between the horizontal sections 71 of at least two adjacent support rods 70. These connecting tubes 73 are straight and flush with the base 10. The support rods 70 are the same width as the flexible support surface 80, providing support and limiting support for the flexible support surface 80, preventing it from exceeding its elastic limit.

[0063] The hinge points 100 between the front leg support bracket 321 and the rear leg support bracket 322, the hinge points 200 between the rear leg support bracket 322 and the fixed bracket 20, and the hinge points 300 between the fixed bracket 20 and the backrest bracket 31 are arranged along the front-to-back direction of the furniture frame. The hinge points 400 between the pull rod 60 and the front leg support bracket 321, the hinge points 500 between the pull rod 60 and the support plate 43, and the hinge points 600 between the support plate 42 and the drive motor 41 located below the backrest bracket 31 are also arranged along the front-to-back direction of the furniture frame.

[0064] The hinge point 400 is located in front of the hinge point 100. Along the front-to-back direction of the furniture frame, the hinge point 400 is located in the middle of the front leg support bracket 321, so that the force of the pull rod 60 is transmitted to the entire front leg support bracket 321 and drives the front leg support bracket 321 to rotate.

[0065] Hinge point 500 is located between hinge point 200 and hinge point 100 and below hinge point 200. Hinge points 200 and 500 are located at either end of the hypotenuse of support plate 43, forming a roughly triangular frame that provides greater stability. Hinge point 600 is located behind hinge point 300 and below hinge point 200. Hinge points 300 and 600 are located at either end of the hypotenuse of support plate 42, forming a roughly triangular frame that provides greater stability.

When the drive motor 41 drives the rear leg support bracket 322 to rotate, the lever arm is longer, and the drive is more labor-saving.

[0067] A hinge point 800 is formed between the drive motor 41 located below the backrest bracket 31 and the backrest bracket 31. This hinge point 800 is located in the middle of the backrest bracket 31, along the front-to-back direction of the backrest bracket 31. This hinge point 800 is located on the side of the rigid support surface 90 that is closest to the flexible support surface 80. When the drive motor 41 rotates the backrest bracket 31, the lever arm is long, reducing the amount of effort required.

[0068] When the furniture frame is in the extended position, the fixed bracket 20, backrest bracket 31, and leg support bracket 32 ​​are coplanar and horizontal. When the furniture frame is in the first lifting position, the fixed bracket 20 is horizontal, the backrest bracket 31 and rear leg support bracket 322 are tilted, and the front leg support bracket 321 is parallel to the fixed bracket 20. When the furniture frame is in the second lifting position, the fixed bracket 20 is horizontal, the backrest bracket 31, front leg support bracket 321, and rear leg support bracket 322 are tilted. When the furniture frame is in the third lifting position, the fixed bracket 20, front leg support bracket 321, and rear leg support bracket 322 are horizontal and coplanar, and the backrest bracket 31 is tilted.

[0069] The present application also provides a piece of furniture, comprising a base plate and the above-mentioned furniture frame, wherein the furniture frame is arranged on the base plate, and the base 10 is fixed to the base plate.

[0070] According to an embodiment of the present application, the furniture frame also has an angle memory function and a one-touch reset function. When the user uses the furniture, the furniture frame memorizes the tilt angles of the backrest bracket 31, front leg support bracket 321, and rear leg support bracket 322 during use. When the user uses the furniture again, the furniture frame can quickly adjust to the last used state.

[0071] According to the embodiment of the present application, the furniture frame can be used on furniture such as sofas or beds that need to adjust the backrest and leg support. In addition, the furniture frame is also used for the chaise longue position in a sofa combination.

[0072] The drive mechanism 40 of the present application drives the rotating bracket 30 to rotate relative to the fixed bracket 20, enabling adjustment of the furniture frame at various angles and improving user comfort. Furthermore, the drive mechanism 40 is offset to prevent the center of the fixed bracket 20 from collapsing during use, which would interfere with the drive mechanism 40 and thus extend the lifespan of the furniture frame.

[0073] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
