Motorized bed

A motorized bed comprising:

• a bed frame comprising a first cross bar and a second cross bar;
• a footrest rotatably mounted to the bed frame, the footrest comprising a mounting end rotatably mounted to the bed frame and an opposite free end, the free end of the footrest located closer to the first cross bar than the second cross bar;
• a footrest actuator mounted between the footrest and the first cross bar and configured to drive the footrest to rotate relative to the bed frame;
• a backrest rotatably mounted to the bed frame, the backrest comprising a mounting end rotatably mounted to the bed frame and an opposite free end, the free end of the backrest located closer to the second cross bar than the first cross bar;
• a backrest actuator mounted between the backrest and the second cross bar and configured to drive the backrest to rotate relative to the bed frame;
• and
• a linkage part fixedly connected between a middle of the first cross bar and the second cross bar such that one of the backrest actuator and the footrest actuator is substantially in line with the linkage part in a way a force introduced by either of the footrest actuator and the backrest actuator is supported by both of the first cross bar and the second cross bar,
• wherein the linkage part reaches from the first cross bar directly to the second cross bar;
• and
• wherein a supporting piece fixedly connected with a substantially middle portion of the mounting end of the backrest is rotatably connected with the linkage part.

A motorized bed comprising:

• a bed frame comprising a substantially rectangular frame body, a first cross bar and a second cross bar connected to the frame body, and supporting legs arranged at corners of the frame body;
• a footrest rotatably mounted to the frame body, the footrest comprising a mounting end rotatably mounted to the bed frame and an opposite free end, the free end of the footrest located closer to the first cross bar than the second cross bar;
• a footrest actuator mounted to the first cross bar and configured to drive the footrest to rotate relative to the bed frame;
• a backrest rotatably mounted to the bed frame, the backrest comprising a mounting end rotatably mounted to the bed frame and an opposite free end, the free end of the backrest located closer to the second cross bar than the first cross bar;
• a backrest actuator mounted to the second cross bar and configured to drive the backrest to rotate relative to the bed frame;
• a linkage part having one end fixedly connected to the first cross bar and the other end fixedly connected to the second cross bar, the linkage part located at a substantially middle area of the motorized bed;
• and
• an additional leg connected to the linkage part to support the substantially middle area of the motorized bed.
