The invention discloses a hospital bed capable of automatically transferring a patient. The hospital bed capable of automatically transferring the patient comprises a bed frame, a bed board which is arranged on the bed frame, a bed sheet which covers the bed board, and a motor, wherein rotary clamping assemblies are arranged on the head portion of the bed frame and on the tail portion of the bed frame, limiting assemblies which correspond to the clamping assemblies are fixed on the bed board, and the motor is connected with the clamping assemblies. According to the hospital bed capable of automatically transferring the patient, the patient does not need to be touched, the bed board can be directly transferred onto a cart, then the patient on the bed board can be transferred into an operating room, and people just need to push the bed board along the edge of the hospital bed to enable the bed board to be clamped and connected to the bed frame smoothly when the patient needs to be transferred back from the operating room; the patient can lie flat on the bed board in the whole process and can not shake, recovery of the patient is facilitated, and burden of medical staff is also reduced; meanwhile, full automatic control of the hospital bed is achieved, labor is saved, the speed is higher, and efficiency is higher.
