Electrically Elevated Baby Crib

Abstract

An electrically elevated baby crib comprises a crib frame and a lifting mechanism fixed inside of the crib frame. The lifting mechanism comprises a bottom support frame, a bed board bracket and a support assembly disposed between the bottom support frame and the bed board bracket. The support assembly includes a first and second support arms intersecting and hingedly connecting with each other by a central axis at the intersection joint. At one side of the support assembly, the upper portion of the first support arm and the lower portion of the second support arm respectively are hingedly connected to the bed board bracket and the bottom support frame, and at opposite side of the support assembly, the lower portion of the first support arm and the upper portion of the second support arm respectively are slidably connected to the bottom support frame and the bed board bracket.

1 . An electrically elevated baby crib comprising a crib frame and a lifting mechanism which comprises:
 a bottom support frame ( 1 ) disposed inside of the crib frame at a lower portion thereof;   a bed board bracket ( 2 ) disposed above the bottom support frame ( 1 ) for supporting a bed board;   a support assembly ( 3 ) disposed between the bottom support frame ( 1 ) and the bed board bracket ( 2 ), which is consisted of a first and second support arms ( 31 ,  32 ) intersecting and hingedly connecting with each other by a central axis at the intersection joint A, at one side of the support assembly ( 3 ), the upper portion of the first support arm ( 31 ) being hingedly connected to the bed board bracket ( 2 ) and the lower portion of the second support arm ( 32 ) being hingedly connected to the bottom support frame ( 1 ), and at the opposite side of the support assembly, ( 3 ) the lower portion of the first support arm ( 31 ) being slidably connected to the bottom support frame ( 1 ) and the upper portion of the second support arm ( 32 ) being slidably connected to the bed board bracket ( 2 ); and   an electric elevator for driving the support assembly, one end of which is rotatably connected to the lower portion of the first support arm ( 31 ) and spaced from the central axis, and the other end of which is rotatably connected to the upper portion of the second support arm ( 32 ) and spaced from the central axis;   wherein the lifting mechanism further comprises an electric motor for driving the electric elevator, which is driven by a low-voltage direct current power supply, wherein the low-voltage direct current power supply consists of a plurality of batteries.   
     
     
         2 . The electrically elevated baby crib as claimed in  claim 1 , wherein the bottom support frame ( 1 ) and bed board bracket ( 2 ) respectively are provided with a guide rail, and the lower portion of the first support arm ( 31 ) and the upper portion of the second support arm ( 32 ) respectively sliding along the guide rail by a roller. 
     
     
         3 . The electrically elevated baby crib as claimed in  claim 1 , wherein the support assembly ( 3 ) comprises two set of first and second support arms ( 31 , 32 ), the two first support arms ( 31 ) of the support assembly ( 3 ) substantially being parallel to each other and the two second support arms ( 32 ) of the support assembly ( 3 ) substantially being parallel to each other, a first connecting rod being connected between the two parallel first support arms ( 31 ) with two ends respectively being connected with the lower portions of the two first support arms ( 31 ) and spaced from the central axes, and a second connecting rod being connected between the two parallel second support arms ( 32 ) with two ends respectively being connected with the upper portions of the two second support arms ( 32 ) and spaced from the central axes. 
     
     
         4 . The electrically elevated baby crib as claimed in  claim 3 , wherein the electric elevator has a driving end and an operating end which are hingedly connected with the first and second connecting rods respectively. 
     
     
         5 . (canceled) 
     
     
         6 . The electrically elevated baby crib as claimed in  claim 1 , wherein a fixing base is disposed inside of the crib frame at a lower portion thereof for fixing the plurality of batteries. 
     
     
         7 . The electrically elevated baby crib as claimed in  claim 1 , wherein the electric elevator is an electric drive pusher. 
     
     
         8 . The electrically elevated baby crib as claimed in  claim 1 , wherein a control switch of the electric elevator is disposed at one side of the crib frame. 
     
     
         9 . The electrically elevated baby crib as claimed in  claim 1 , wherein the crib frame is provided with a guardrail. 
     
     
         10 . The electrically elevated baby crib as claimed in  claim 1 , wherein multiple wheels are disposed at bottom of the crib frame.
