Automatic accompanying bed

Abstract

The invention relates to the field of furniture and particularly discloses an automatic accompanying bed. The automatic accompanying bed comprises at least three bottom plates, wherein the adjacent bottom plates are hinged, a buffer layer is fixed to the top of each bottom plate, supporting legs are fixed to the bottom of the bottom plate at one side, and a supporting frame is hinged to the bottomof the bottom plate at the other side; a pull rope is fixed to the bottom plate where the supporting legs are fixed, and a stepping motor capable of rolling the pull rope is fixed to the supporting frame; a heating cavity is formed in each bottom plate, a plurality of hot air channels are formed in the top wall of each heating cavity, a piston is connected into each hot air channel in a verticalsliding mode, each piston is higher than the top of the corresponding bottom plate, a spring is fixed between each piston and the inner wall of the corresponding heating cavity, and each piston is provided with an exhaust channel which communicates with the corresponding heating cavity in the slide-down process; and each buffer layer is provided with a plurality of through holes, and each heatingcavity communicates with an air-in piece and a heating piece. According to the scheme, the accompanying bed can be unfolded slowly and automatically without being unfolded by manpower completely, andthe situation that a large sound is generated in the unfolding process is avoided.

Description

Technical field [0001] The invention relates to the field of furniture, in particular to an automatic companion bed. Background technique [0002] Accompanying beds can facilitate patients' family members to rest in the ward at night, and can be folded during the day, and will not hinder the walking of other personnel, doctors or nurses in the ward. At present, each hospital bed is equipped with at least one accompanying bed. The companion bed is in the shape of a seat when folded during the day. When used at night, it is necessary to manually push the lower ends of the folded parts away from each other to expand the companion bed into a bed shape. [0003] For example, the patent application number 201820633010.2 discloses a folding accompany bed chair, including a support frame, a back plate, a front back plate, and a seat plate. The support frame and the back plate are rotatably connected, and the back plate and the front The back board is connected in rotation, and the front b...

Problems solved by technology

[0004] However, the current companion bed is completely dependent on manual deployment, and manual deployment cannot fully and accurately grasp the strength of the deployment, resulting in excessive force, the companion bed unfolds rapidly, and the legs of the companion bed collide with the ground or move relative to each other, resulting in loud noises

Since the accompanying bed is generally used at night, and the patients in the hospital bed are generally suffering from serious diseases and need to rest, the sudden sound can easily disturb the patients
