Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1 to 5, the present invention provides an electric sofa bed, which includes a base frame 1, a seat frame 2 disposed on the base frame 1, and a backrest frame 3 disposed at the rear of the seat frame 2. The base frame 1 is a rectangular frame and is provided with a plurality of springs 71 at intervals along the length direction thereof, thereby providing a backrest resilience force for a sofa user. The seat frame 2 comprises a rectangular frame and a plurality of supporting legs arranged on one side of the rectangular frame, and the rectangular frame of the seat frame 2 is also provided with a plurality of springs 71 at intervals along the length direction thereof, so as to provide the seating resilience force for a sofa user. The lower ends of the rectangular frame and the supporting legs of the seat frame 2 are also provided with a plurality of third pulleys 9, so that the seat frame can slide out and slide into the base frame 1. The base frame 1 is a support frame consisting of a plurality of horizontal frames and vertical frames to provide better support for sofa users.
In this embodiment, the base frame 1, the seat frame 2, and the backrest frame 3 are all formed by welding square metal tubes. The seat frame 2 and the backrest frame 3 are provided with a plurality of hooks 72 for hanging the springs 71.
Referring to fig. 2-3, the electric sofa bed further includes a first guiding mechanism disposed between the backrest frame 3 and the seat frame 2 and used for guiding the backrest frame 3 to swing, a second guiding mechanism disposed between the base frame 1 and the seat frame 2 and used for guiding the seat frame 2 to horizontally slide, a driving mechanism disposed between the backrest frame 3 and the base frame 1 and used for driving the backrest frame 3 to swing, and a return spring 54 disposed between the base frame 1 and the seat frame 2 and used for driving the seat frame 2 to horizontally slide out of the base frame 1 in a direction away from the backrest frame 3.
Specifically, the first guiding mechanism is a supporting arc rod 41 disposed on the backrest frame 3 and a guiding plate 42 disposed on the seat frame 2, the guiding plate 42 is provided with a sliding slot 421 in a waist-shaped hole shape, and the supporting arc rod 41 is provided with a first pulley 411 in sliding fit with the sliding slot 421. The second guiding mechanism is a moving plate 51 disposed on the seat frame 2 and having an inverted L shape, and a slide rail 52 disposed on the base frame 1, the moving plate 51 is provided with a second pulley 511 slidably engaged with the slide rail 52, and the slide rail 52 is provided with a baffle 53 for limiting the second pulley 511 to slide. The driving mechanism comprises a driving motor 61 and a traction rod 62 connected with the output end of the driving motor 61, the driving motor 61 is hinged on the base frame 1, and the traction rod 62 is hinged on the backrest frame 3.
