An electric bed includes a base frame, a movable frame slidably disposed on the base frame and moveable backward and forward, a back frame having a rear end pivotally connected with the movable frame, and a driving member extendable and retractable in length, having a rear end pivotally connected with the movable frame and located below the rear end of the back frame, and a front end pivotally connected with the back frame. A linkage has a front end pivotally connected with the base frame, and a rear end pivotally connected with the back frame and located between the rear end of the back frame and the front end of the driving member. When the driving member extends longer, the back frame is rotated upwardly to enable the rear end of the back frame and the movable frame to horizontally move forward together.一種電動床,包括有一底架、一活動架、一背架、至少一連桿以及一驅動件,其中該活動架設於該底架並可沿該底架之前後方向滑動,該背架以其後端樞設於該活動架,該驅動件之後端樞設於該活動架並位於該背架後端下方,該驅動件之前端則樞設於該背架,該連桿之前端樞設於底架,該連桿後端則樞設於該背架並位於該背架後端與該驅動件前端之間;藉此,當該驅動件伸長時,該背架不僅可向上旋擺,該背架的後端更可連同活動架一起朝床頭方向水平移動,如此一來,便能減緩使用者的腹部由躺姿轉為坐姿時感到的壓迫與不適,且方便使用者於坐姿狀態取放置於床頭的物品。10‧‧‧電動床12‧‧‧前方14‧‧‧後方20‧‧‧底架22‧‧‧腳輪24‧‧‧滑軌30‧‧‧活動架32‧‧‧縱桿34‧‧‧豎桿341‧‧‧頂端36‧‧‧橫桿40‧‧‧背架41‧‧‧床板42‧‧‧支撐架421‧‧‧後端423‧‧‧樞轉部44‧‧‧支撐板441‧‧‧底面50‧‧‧連桿52‧‧‧前端54‧‧‧後端60‧‧‧驅動件62‧‧‧缸體64‧‧‧伸縮桿L‧‧‧前後方向
