Abstract

A foldable electric bed includes a front frame having two parallel guide rails, a rear frame pivotally connected with the front frame and swingable between extended and folded positions, a first buttock supporting unit slidably disposed with the guide rails, a back supporting unit pivotally connected with the first buttock supporting unit, a front link pivotally connected with the front frame and the back supporting unit, and a first actuator disposed with the first buttock and back supporting units, such that the first buttock supporting unit is driven by the back supporting unit to slide forwards when the back supporting unit is driven by the first actuator to swing upwardly. As a result, when the electric bed lifts the back of a user, the user may stay near to the head of the bed, facilitating access to items near the bed head and avoiding oppression of the user's abdomen.
