Power-driven nursing bed provided with flexible connection leg bending and stretching mechanism

Abstract

The invention relates to a power-driven nursing bed provided with a flexible connection leg bending and stretching mechanism, comprising a bed board, a bed frame, a linear push rod and a leg bending mechanism, wherein the linear push rod, a side link and the bed frame form a four-bar linkage, the side link, a connecting rod, a second leg bending side link and the bed frame form another four-bar linkage, a telescopic link, the second leg bending side link, a leg bending connecting rod, a foot bed board, a first leg bending side link and the bed frame form a six-bar linkage, and the two four-bar linkages and the six-bar linkage are combined into the flexible connection leg bending and stretching mechanism which converts the rotation of a motor and the telescopic motion of the linear push rod into up-down motion of the bed board of the foot bed board and controls the foot bed board to be lifted and laid flat. The power-driven nursing bed can realize reliable leg bending and stretching motion, the use comfortableness is improved as flexible connection is adopted, and the dual functions of ascending when the leg is bent and laying the leg when the leg is bent can be realized, thus the power-driven nursing bed is applicable to popularization and application.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of an electric nursing bed, in particular, an electric nursing bed with a mechanism for flexibly connecting curved legs. Background technique [0002] The electric nursing bed is a service robot that can improve the self-care ability of bedridden elderly or patients, reduce the work intensity of nursing staff, and reduce the worries of family members. With the continuous improvement of people's life expectancy, the aging population in society is increasing, and the demand for nursing beds is also increasing. With the development of technology and society's attention to the elderly and bedridden patients, there are more and more functional nursing beds, which provide great convenience for the life and treatment of the elderly or bedridden patients. [0003] At present, the main functional forms of the electric nursing bed are: one is to use electric or manual methods to drive the co...
