Full-automatic lifting hospital bed and control method

Abstract

The invention relates to a full-automatic lifting hospital bed and a control method. The full-automatic lifting hospital bed can tilt forwards and backwards and turn to the left side and the right side in a large space. The full-automatic lifting hospital bed comprises a bed frame, a back plate frame, a leg plate frame, a chassis of the bed frame and a program controller. Three columnar lifting motors are distributed in an isosceles triangle on the chassis of the bed frame and are connected with the bed frame which is positioned on the motors through a frame universal joint per se and a connecting universal joint respectively. A fixing frame plate is fixed in the middle of the bed frame, and the back plate frame and the leg plate frame are positioned on two sides of the fixing frame plate. The back plate frame and the bed frame are hinged through a multi-stage hinged power lifting arm, a hinged sliding force arm and a sliding arm, which are positioned in the middle of the back plate frame. The leg plate frame and the bed frame 1 are hinged through a leg plate hinged force arm, a short force arm, a long force arm and a driving lever arm. The full-automatic lifting hospital bed has the advantages that: 1, the full-automatic lifting hospital bed has simple structure, environmental protection and no noise; and 2, due to a design that the back plate frame moves backwards and then tilts, the included angle space between a seat plate and the back plate frame is large; therefore, people feel comfortable, and the spine of human hips cannot be injured.

Description

technical field [0001] The invention relates to a fully automatic lifting medical bed capable of tilting back and forth in a large space and turning sideways and sideways and a control method thereof, belonging to the field of medical bed manufacturing. Background technique [0002] CN2580938Y, the name "hydraulic double-stroke automatic lifting medical bed", mainly includes a bed surface and a bed frame, and is characterized in that the handle arranged in the middle of the bed surface is connected to the front of the bed through a bracket, the upper end of the bracket is connected to the front of the bed, and the lower end is connected to the front of the bed. The angle of the front of the bed can be adjusted by connecting the bracket with the driving device; the handle set in the middle of the bed is connected with the rear of the bed through a hydraulic device and the bracket to adjust the angle of the rear of the bed. The lying position becomes a sitting position. The hy...

Problems solved by technology

Its shortcomings: First, the use of hydraulically controlled medical beds not only has a complex structure, but also inevitably generates noise, which directly affects the medical environment, especially for hospitals, and directly affects the physical rehabilitation of others; There is no function of tilting after moving back, so when the backboard frame is raised, the angle space formed by the seat board and the backboard frame is very small, which not only makes people feel uncomfortable, but also may damage the spine of the human buttocks; The third is that it is impossible to realize the rollover of the human body
