The utility model relates to an electric bed, in which a base frame is connected with a lifting frame and a movable frame, and the lifting frame is connected with the movable frame through a connected structure. The electric bed is equipped with a motor and a telescopic component, which is driven by the motor, so that the lifting frame reciprocates in a lifting position and a lying position relative to the underframe, and the associated movable frame is raised at a certain height in the underframe, or kept roughly horizontal with the underframe.一種電動床，是在一底架連接一揚昇架與一活動架，透過一連動結構使揚昇架和活動架相連。在電動床配置一馬達與一伸縮組件，該伸縮組件被馬達驅動，使揚昇架相對底架在一揚昇位置和一平躺位置往復運動，連帶活動架在底架抬起一定高度，或與底架保持大致水平狀態。
