Title: 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 relative 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.
