The invention belongs to the field of seismic resistance of civil engineering and specifically to a novel automatic anti-seismic bed which is mainly used for lifesaving when a strong shock occurs. In particular, when a strong shock occurs at night, the anti-seismic bed can be automatically started in a short time to protect safety of people on the bed. The anti-seismic bed mainly comprises an acceleration switch, a motor, a fixed bed board, a rotary bedcover and the like. Different acceleration limit values can be set according to different seismic fortification intensity of local buildings; when an earthquake occurs and a shear wave accelerated velocity exceeds a limit value, the acceleration switch is triggered and a circuit is turned on so as to allow the rotary bedcover to be opened until the bed is enclosed. The apparatus is provided with a self-locking zone, when the bedcover completely encloses the bed, self-locking is started to fix the rotary bedcover, so the whole bed forms an approximately-enclosed stable system; and protection materials like sponge are placed in the rotary bedcover to protect safety of people. The apparatus is provided with multiple protection circuits to guarantee effective starting. The limit value of the acceleration switch is adjustable, which facilitates usage of the bed in different regions. A large container is arranged in the bed, which facilitates storage of food, oxygen, emergency supplies and communication articles in the bed.
