Problems solved by technology

The main problems are: 1. When the backrest movable bed surface is lifted, the load on the transmission device is relatively large, especially when the patient's weight is large, the energy consumption is greater
2. The efficiency of the transmission device using the helical pair structure for variable speed (deceleration) is too low

Abstract

A spring balanced differential nursing bed features that the balancing springs are installed to the movable part of nursing bed for balancing the body weight of patient, the planetary gear structure or gear set structure, and flexible member and its winding device are used for drive mechanism, a spring regulator is used to regulate the number of spring for matching the body weight of patient, and a differential unit is used for loading or unloading springs for balancing the torque.

Description

technical field [0001] The invention relates to a nursing bed. Background technique [0002] A general medical care bed is composed of a bed frame, a bed surface, a bed leg and a transmission device. The bed frame is usually made of parts fixed to each other such as the bed frame, the head of the bed, and the tail of the bed. The bed surface or bed panel that carries the human body is usually composed of multiple bed surfaces, such as the backrest movable bed surface, the buttocks fixed bed surface, the thigh movable bed surface, and the calf movable bed surface. The driving device can be mainly divided into two types: manual operation and electric operation, and the screw auxiliary mechanism is generally used for transmission. The backrest movable bed surface is hinged with the fixed bed surface or the bed frame, and the movable bed surface driven by the transmission device makes a rotary motion around the hinge, so that the other end of the movabl...
