Abstract

The utility model relates to an electric backrest adjusting device for a bed. The bottom of a frame of a bed body is fixedly provided with a worm-wheel and worm speed reducer, an output shaft of a motor driving unit is connected with an input shaft of the speed reducer, an output shaft of the speed reducer is connected with a crank, the crank is rotationally connected with a connecting rod, the connecting rod is connected with one end of the backrest by a hinge, and the lower end of the backrest is connected with the frame of the bed body by a hinge. The utility model has the working principle that the backrest, the crank and the connecting rod form a reciprocating motion mechanism of a rocking rod of the crank. The bed backrest is pushed to do angle change corresponding to the bed body. The utility model is suitable for a single bed and a double bed. When the utility model is used on a double bed, two sets of backrests and the devices can be arranged, and the backrests and the devices are independently regulated. The utility model fully considers the rest condition that a sitting posture is used by a person in bed, and expands the use function of the bed head part.

Description

Bed motorized adjustment back-rest means for chair
Technical field
The utility model is a kind of device that is applied on the bed, particularly regulates the motorized adjustment back-rest means for chair that the bed-rest angle of inclination is used.
Background technology
Although the head of a bed part on the existing bed is through distortion and decoration of all shapes and colors, citation form still majority is upright or a little plane inclined.If when considering that the people has quite a few time to take sitting posture in bed, traditional head of a bed backrest does not then often reach comfortable effect, because the angle of inclination of human body needs can't satisfy sitting posture near upright backrest the time, also rational supporting member neck portion.General concept is thought in addition, and bed mainly is used for " sleeping ", rather than " seats ", therefore, the head of a bed of existing most beds is partly many than comfortableness for ornamental consideration in design.Other has some at comfortableness problem the backrest with simple adjustment function to be installed, but adopts the often cumbersome of manual adjustments, and its practical effect is limited.
Summary of the invention
The purpose of this utility model is, a kind of bed back rest that can regulate the angle of inclination in a big way is provided, can be according to people's concrete sensation motorized adjustment at that time to reach satisfied level of comfort.Bed with motorized adjustment back-rest means for chair structure is, be installed with decelerator 4 in bed body framework 2 bottoms, electric-motor drive unit 3 output shaft connection reducer power shafts, reducer output shaft connecting crank 5, the crank connecting rod 6 that is rotationally connected, connecting rod connects backrest 7 one ends by hinge 8, and the backrest lower end connects bed body framework by hinge 9; Backrest 7, crank 5 constitute the crank rocker reciprocating mechanism with connecting rod 6.
Operation principle of the present utility model is that backrest 7, connecting rod 6 and the crank 5 common crank rocker reciprocating mechanisms of forming promote backrest 7 and do the angle variation with respect to bed body 1.
The utility model is applicable to single bed or double bed.When on double bed, using, two cover backrest and this device, independent regulation separately can be installed.
The utility model has taken into full account the rest situation that people adopt sitting posture in bed, has expanded the function of use of head of a bed part.
