Variable chair type electric bed

Abstract

The present disclosure relates to the technical field of electric beds, and discloses a variable chair type electric bed. The variable chair type electric bed comprises a bed frame, a bed board set, an electric telescopic rod and a guide part. After the electric bed is changed into a chair, one end of a bed board serving as a seat board is tilted, so that a human body can sit more stably and safely.

What is claimed is: 
     
         1 . A variable chair type electric bed, comprising:
 a bed frame;   a bed board set, being arranged on the bed frame in a sliding mode, and the bed board set at least comprising two bed boards connected in a hinged mode;   an electric telescopic rod, the extending end of which being hinged to the bed board on the outermost side of one side of the bed board set, and the fixed end of the electric telescopic rod being hinged to any bed board except the bed board on the outermost side; and   a guide part, being fixedly arranged on the side, located at the output end of the electric telescopic rod, of the bed frame, and the guide part being assembled to enable the extending end of the electric telescopic rod to do lifting motion in the guide part, enable the bed board set to be in a straight state when the extending end ascends to the highest position and enable the bed board connected with the extending end to be in a state that the downward swinging angle is less than 90 degrees when the extending end descends to the lowest position.   
     
     
         2 . The electric bed according to  claim 1 , wherein the bed board set comprises the two bed boards connected in the hinged mode, the extending end and the fixed end of the electric telescopic rod are hinged to the two bed boards respectively, and after the extending ends of the two bed boards are assembled to descend, the ends, hinged to the other bed board, of the bed board corresponding to the fixed end can tilt upwards. 
     
     
         3 . The electric bed according to  claim 1 , wherein the bed boards comprise a plurality of bed boards connected in the hinged mode in sequence, one bed board is arranged between the bed board hinged to the fixed end of the electric telescopic rod and the bed board hinged to the extending end of the electric telescopic rod, and after the extending ends of the bed boards descend, the joint of the bed board corresponding to the extending end and the other bed board has an upward lifting process. 
     
     
         4 . The electric bed according to  claim 1 , wherein the guide part is a longitudinally distributed guide rail, the guide rail is provided with a U-shaped guide groove, limiting grooves communicating with the guide groove are formed in the two side faces of the guide rail, the extending end of the electric telescopic rod is located in the guide groove, and limiting rods extending into the limiting grooves are arranged on the two sides of the electric telescopic rod. 
     
     
         5 . The electric bed according to  claim 1 , further comprising an auxiliary bed frame, wherein the auxiliary bed frame is arranged on the bed frame in the sliding mode, and the bed board set is arranged on the auxiliary bed frame. 
     
     
         6 . The electric bed according to  claim 2 , further comprising an auxiliary bed frame, wherein the auxiliary bed frame is arranged on the bed frame in the sliding mode, and the bed board set is arranged on the auxiliary bed frame. 
     
     
         7 . The electric bed according to  claim 3 , further comprising an auxiliary bed frame, wherein the auxiliary bed frame is arranged on the bed frame in the sliding mode, and the bed board set is arranged on the auxiliary bed frame. 
     
     
         8 . The electric bed according to  claim 4 , further comprising an auxiliary bed frame, wherein the auxiliary bed frame is arranged on the bed frame in the sliding mode, and the bed board set is arranged on the auxiliary bed frame. 
     
     
         9 . The electric bed according to  claim 5 , wherein the bed board set comprises a bed board I, a bed board II, a bed board III, a bed board IV, a bed board V and a bed board VI which are hinged in sequence, the extending end is connected to the bed board II, the fixed end is connected to the bed board IV, and when the bed board I and the bed board II swing downward till vertical states, the connecting end of the bed board III and the bed board II can tilt upwards.
