Abstract: [Objective] The use of intelligent disinfection instead of manual disinfection and the construction of multifunctional medical garages provide new ideas for solving the problem of parking difficulties in large medical facilities, which can improve the utilization rate of traditional garages and prevent cross infection of viruses in hospitals. [Method] The research group first used the three-dimensional modeling software NX to establish a simplified model of the garage structure, and then separately described the structural design of the parking limit device of the semi embedded multi-functional medical garage, the structural design of a Speed bump with the function of anti sliding on the slope, the structural design of the degree of freedom movable car washing device, and the design of the car carrier plate. [Result] Through strength load analysis of key components, it was found that: 1) The minimum diameter of the extension pin is 47.8 mm, and the diameter of the extension pin in this garage is 50 mm, which is greater than the minimum diameter. 2) Bending normal stress σmax=43.8 N/mm2 ﹤ Bending stress design value f=295 N/mm2 ; Maximum Shear stress of bearing τmax=34 N/mm2 ﹤ Design value of Shear stress resistance fv=180 N/mm2 ; Relative deflection v2=∫∫(M(x)/ EI) dxdx+Cx+D= 1/325.5﹤ Deflection control value [v]= L/300. [Conclusion] The design has good structural performance, meets various indicator requirements, and to a certain extent solves the safety issues of the existing three-dimensional garage, ensuring the health of doctors and patients.
