Abstract：The research was about the structure design of trolley for fruits' storage with no losses in mountain orchard. The apples in Yantai Shandong, one kind of mountain fruits, were selected as the experimental objects. In combination with circuit design, machine design, industry design, ergonomics and other aspects of knowledge, the structure of intelligent trolley for lossless storage was designed. Firstly, the material of the car was determined and the preliminary structure design came out, whose reasonability the structure design of trolley for storage with reduced losses in mountains based on the mechanical characteristics of apples' pressures tested by the simulations. Then, the following designs based on the shape-state optimization and control system of ergonomics determined the size of the car. Finally, a series of experiments including the setting up, weighing and earthquake resistance of the entity were carried out. According to the experimental data, the effect of the diminishing loss was analyzed. The experimental results show that the car in the research has preeminent earthquake resistance. The overall aseismic ratio comes up to 41.6％ and the protection ratio of the experimental material reach to 58.3％.The research provides technical supports in the design of smart devices for the storage of mountain fruits.
