Motorized mechanism and motorized furniture

Abstract

A motorized furniture and a motorized mechanism are provided. The motorized furniture includes a furniture frame and a platform supported on the furniture frame. The platform includes a backrest rotatable relative to the furniture frame. The backrest includes a first backrest section, a second backrest section, and an actuator. The second backrest section is rotatably connected with the first backrest section. The actuator is mounted to the backrest and configured to drive the first backrest section and the second backrest section to rotate relative to each other to thereby form a convex upwards fold.

         9 . The motorized furniture of  claim 8 , wherein the platform defines a foot end and an opposite head end along a longitudinal axis of the platform, the first backrest section is closer to the foot end of the platform than the second backrest section along the longitudinal axis, and the second backrest section is greater than the first backrest section in length along the longitudinal axis. 
     
     
         10 . A motorized mechanism comprising:
 a platform defining a longitudinal axis, the platform comprising:
 a fixed section; 
 a first rotatable section rotatable relative to the fixed section, the first rotatable section having a first end and an opposite second end along the longitudinal axis, the first end adjacent the fixed section; and 
 a second rotatable section rotatably connected with the first rotatable section, the second rotatable section having a third end and an opposite fourth end along the longitudinal axis, the third end adjacent the second end of the first rotatable section; 
   a first actuator connected and configured to drive the first rotatable section and the second rotatable section to rotate relative to each other to form a convex support surface; and   a second actuator connected and configured to drive the first rotatable section and the second rotatable section as a whole to rotate relative to the fixed section.   
     
     
         11 . The motorized mechanism of  claim 10 , wherein the first rotatable section has a first length along the longitudinal axis, the second rotatable section has a second length along the longitudinal axis, and the first length is less than the second length. 
     
     
         12 . The motorized mechanism of  claim 10 , wherein the second rotatable section and the first rotatable section are rotatably connected to each other with a hinge 
     
     
         13 . The motorized mechanism of  claim 10 , wherein the first actuator is a first linear motor having two opposite ends, one of which is pivotally connected to the first rotatable section, and the other pivotally connected to the second rotatable section. 
     
     
         14 . The motorized mechanism of  claim 13 , wherein the first linear motor is at its greatest length when the first rotatable section is coplanar with the second rotatable section. 
     
     
         15 . The motorized mechanism of  claim 13 , wherein the second actuator is a second linear motor connected to an underside of the second rotatable portion.
