1. A motorized bed comprising:
- a bed body; and
at least one driving device connected with the bed body;
wherein the bed body includes;
a base frame;
a fixed frame fixedly mounted on the base frame; and
at least one movable frame pivotally movable relative to the fixed frame and the base frame;
wherein the driving device includes;
a drive unit pivotally mounted on the fixed frame of the bed body;
a guide tube mounted on the drive unit;
a threaded rod rotatably mounted in the guide tube and driven by the drive unit;
an actuating source connected with the drive unit to drive the threaded rod;
an extension tube movably mounted in the guide tube and having a first end provided with a push portion movable in the guide tube and a second end provided with a pivot portion pivotally connected with the movable frame of the bed body to drive and move the movable frame of the bed body relative to the fixed frame of the bed body; and

Abstract
A motorized bed includes a bed body and a driving device. The bed body includes a base frame, a fixed frame, and a movable frame. The driving device includes a drive unit mounted on the fixed frame, a guide tube mounted on the drive unit, a threaded rod mounted in the guide tube, an extension tube mounted in the guide tube and having a first end provided with a push portion and a second end connected with the movable frame, and a threaded mover moved by the threaded rod and movable to abut the push portion. Thus, when a human body is disposed between the movable frame and the base frame, the human body only needs to overcome the weight of the movable frame to detach the extension tube from the mover, so that the movable frame stops moving immediately.
