Abstract

In order to realize stable and safe operation of multi-mode bed back support mechanism, various angle adjustment mechanisms are studied and analyzed. An angle adjustment mechanism using a guide mechanism is proposed. The function of back support is achieved by using an electric push rod. A model of the back support mechanism was built. Based on the analysis of the geometric relationship and mechanical model of the back support mechanism, the optimal solution of the fixed position of the electric actuator was solved by using MATLAB. Dynamic simulation, performed by SOLIDWORKS Motion, determine the optimal stroke of the electric actuator. Finite element analysis, performed by SOLIDWORKS Simulation, verify the feasibility of the back support mechanism. The simulation results show that using the back support mechanism of the guide rod mechanism reduces the load of the load beam, improves the safety of the back support mechanism, and stabilizes the back support process.
