Abstract: This design is to modify the cargo space to make it layered and adjustable,to keep the current couriers away from turning the whole cargo space up and down with all the cargoes of different shapes and sizes piled up at the same cargo space.According to the size or weight of the package,it is reasonable to divide the cargo space into three spaces,the upper,the middle and the lower space.The bottom surface of upper space is adopted with guide rail structure and the bottom surface of the middle space is adopted with parallelogram structure,both of which can be moved in parallel translation.The middle space and the lower space can be also adjusted according to the size of the package with usage of the electric telescopic rod.It is able to make the express simpler and more efficient with easier placing and picking,enlarge the load capacity,ensure the good condition of the items during loading and unloading in the express.The structure design is simple and reasonable,and the material of the parts is very common with low cost and easy market popularization.

Key words: express truck, cargo space, layered structure, adjustable space, parallel translation

摘要： 设计改造一种分层空间可调式快递小车载运仓,改变形状、体积不同的快件在一个载运仓中层层堆积,快递员"翻箱倒柜"找寻快件的现状。根据包裹大小轻重,合理将载运仓分上、中、下3个空间,上层空间底板采用导轨结构,中层空间的底板采用平行四边形结构,都可以平移推拉;中层空间和下层空间可根据包裹大小采用电动伸缩杆适当调整。该载运仓方便了快递员对快件的查找、取放,增大了装载容量,还能保证在装卸、运输途中快件的完好性,使派件简单化、效率化;其结构设计简单合理,所用零件材料都很常见且成本低廉,易于市场化推广。
