Inner frame for motor-driven mattress

Abstract

Disclosed is a motor-driven mattress inner frame, comprising: a head frame ( 100 ), a main frame ( 200 ) and a foot frame ( 300 ), wherein a head motor ( 600 ) and a foot motor ( 700 ) are arranged in the middle part of the main frame ( 200 ). The head frame ( 100 ) and the main frame ( 200 ) are detachably connected to two ends of a first hinge ( 400 ) respectively. A driving shaft of the head motor ( 600 ) drives one end of the first hinge ( 400 ) which is connected to the head frame ( 100 ) and enables the head frame ( 100 ) to rotate relatively to the main frame ( 200 ). The main frame ( 200 ) and the foot frame ( 300 ) are detachably connected to two ends of two second hinges ( 800 ) respectively; two connecting rods ( 805, 806 ) are arranged in parallel on the second hinge ( 800 ). A pair of opposite linkages ( 806 ) is fixed with a rotatory shaft ( 801 ) which is driven to rotate by the foot motor ( 700 ). The rotatory shaft ( 801 ) rotates and the movement thereof is converted by the linkages ( 805, 806 ) into an up and down translation of the foot frame ( 300 ). The inner frame of a motor-driven mattress has the advantages of being convenient to assemble and disassemble, having a simple structure and being able to be folded in accordance with ergonomics.

1 . A motor-driven mattress inner frame consists of characteristics as follows: It is composed of a head frame, a main frame and a foot frame, wherein a head motor and a foot motor are arranged in the middle part of the main frame. The head frame and the main frame are detachably connected to two ends of a first hinge respectively. A driving shaft of the head motor drives one end of the first hinge which is connected to the head frame and enables the head frame to rotate relative to the main frame. The main frame and the foot frame are detachably connected to two ends of two second hinges respectively; two connecting rods are arranged in parallel on the second hinge. A pair of opposite linkages is fixed with a rotatory shaft which is driven to rotate by the foot motor. The rotatory shaft rotates and the movement thereof is converted by the linkages into an up and down translation of the foot frame.

         3 . The motor-driven mattress inner frame described according to  claim 2  consists of characteristics as follows: At least one third bulge is inwardly set up on each end of the described third hinge. A third groove that matches the third bulge is set up on the side of the described head frame or the main frame. 
     
     
         4 . The motor-driven mattress inner frame described according to  claim 1  or  claim 2  consists of characteristics as follows: The described first hinges are the two set up on the two sides of the head motor. At least two screw holes are set up on each end of the described first hinge. The both up and down sides of the described first hinge are extended to the head frame and main frame. 
     
     
         5 . The motor-driven mattress inner frame described according to  claim 1  consists of characteristics as follows: There is a fixed support frame on the described rotating shaft. The drive shaft of the described foot motor is connected to the support frame. 
     
     
         6 . The motor-driven mattress inner frame described according to  claim 1  consists of characteristics as follows: At least one first bulge is inwardly set up on each end of the described first hinge. A first groove that matches the first bulge is set up on the side of the described head frame or the main frame. At least one second bulge is inwardly set up on each end of the described second hinge. A second groove that matches the second bulge is set up on the side of the described foot frame or the main frame.
