Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to an electric folding sofa bed. Background Art

[0002] The electric folding sofa bed is a multifunctional piece of furniture, driven by electric components. It mainly includes a fixed sofa seat and a seat board and a backrest board movably arranged on the sofa seat. When folded, it presents a sofa shape. When stretched, the seat board and the backrest board are on the same horizontal plane and can be used as a simple bed.

[0003] The mainstream electric folding sofa beds on the market now have an L-shaped seat that slides directly outward, and the sofa backrest is composed of two sets of back panels that fold against each other. When the L-shaped seat slides outward, the two sets of back panels unfold and form a plane together with the top of the L-shaped seat, which has good stability. However, in actual use, in order to ensure the practicality of the sofa function, the length of the L-shaped seat is controlled at about 60 cm. After the two sets of back panels are folded, since a headrest cannot be installed on the top, the height needs to be controlled at about 45 cm so that the head can be prevented from hitting the top of the sofa backrest. This makes the actual length of the entire device after unfolding 1.5 meters, which makes the device not long enough when used as a bed. At the same time, since the two sets of back panels need to be folded and pressed against each other, an embedded retractable headrest cannot be made on the back side. If an external headrest is made, the entire device cannot be placed completely against the wall when folded into a sofa. In order to solve the above problems, a special electric folding sofa bed is provided. Utility Model Content
