Description

Technical Field

[0001] This utility model relates to the field of seating technology, and in particular to an electric sofa bed support. Background Technology

[0002] Beds are the most widely used furniture items in daily life. In the current technology, beds can usually only support the mattress and provide a place for users to sleep, but cannot be transformed into the shape of a sofa for users to use as a sofa.

[0003] With technological advancements, foldable sofa beds have gradually emerged in existing technologies. For example, Chinese patent document CN203873368U discloses a novel sofa bed, comprising a steel frame bed, a mattress, a remote control, and a receiver. The mattress is placed on the steel frame bed, which includes a seat cushion, a backrest, and a support section. The backrest is hinged to the seat cushion and support section at both ends, respectively. A support frame is located at the other end of the support section. An electric push rod is located at the bottom of the seat cushion and is hinged to it. The receiver receives signals from the remote control. Support legs are located at the bottom of the seat cushion, and casters are located at the bottom of the support legs. A connecting bracket is located on the backrest and is hinged to the electric push rod. This sofa bed allows for easy folding and unfolding, making it more convenient for people to rest.

[0004] However, the sofa bed disclosed in Chinese patent document CN203873368U has the following defects: when the sofa bed is folded, it can only tilt and raise the backrest to support the user's head and back, but cannot support and raise the user's thighs and calves, making it difficult to meet the needs of different users. Utility Model Content

[0005] The technical problem this utility model aims to solve is to address the shortcomings of the existing technology by providing an electric sofa bed frame. When unfolded, this electric sofa bed frame allows users to lie down and rest. When tilted and raised, the head and back supports provide support for the user's head and back. When tilted and raised, the thigh and lower leg supports together lift and support the user's thighs and lower legs, thus meeting the needs of different users.

[0006] To solve the above-mentioned technical problems, the present invention provides an electric sofa bed support, comprising a bottom support, a hip support, a head and back support, a thigh support, a calf support, a first motor, a first telescopic push rod, a second motor, a second telescopic push rod, and a support rod. The hip support is fixed to the bottom support, and the right end of the head and back support is rotatably connected to the left end of the hip support. The first motor is mounted on either the hip support or the bottom support, and the power output end of the first motor is connected to the first telescopic push rod, which is connected to the head and back support. Under the driving action of the first motor... The first telescopic push rod can push the left end of the head and back support to rise or fall; the left end of the thigh support is rotatably connected to the right end of the hip support; the second motor is mounted on the hip support or the bottom support, and the power output end of the second motor is connected to the second telescopic push rod, which is connected to the thigh support. Under the drive of the second motor, the second telescopic push rod can push the right end of the thigh support to rise or fall; the left end of the calf support is rotatably connected to the right end of the thigh support; the front end of the support rod is rotatably connected to the calf support; and the rear end of the support rod is rotatably connected to the bottom support.
