The invention discloses a multipurpose electric vehicle. The multipurpose electric vehicle comprises all technologies of loaded long pieces of a four-wheel electric vehicle and a five-wheel electric vehicle. An electric vehicle carriage is designed to be capable of being lengthened at will within a specified size so as to adapt to carried long pieces. According to the specific implementation scheme, a vehicle chassis and a carriage girder are arranged by means of sleeving small parts with large parts; a pulley and a steel wire rope are used for rotation and shaking of parts (5) and (6) to extend or shorten the carriage to adapt to loading of long pieces. The technical characteristics of the multipurpose electric vehicle are positive and negative rotation of a trapezoidal screw and installation of a hydraulic system to control extension and contraction of the carriage. Power is provided for front wheels of a tricycle, potential resources of the tricycle can be explored as much as possible when the tricycle is designed to be a five-wheeled tricycle, and the multipurpose electric vehicle has great popularization and practical values.

    本发明公开了多用电动车,包括四轮电动车、五轮电动车装载长件的全套技术。主要是将电动车车箱设计成可以在规定尺寸里任意延长以适应运载长件。具体实施方案是将车辆底盘和车箱大梁以大套小,采用滑轮、钢丝绳旋转摇动(5)和(6)延长、收缩车箱长度,以适应装载长件。梯形螺杆正、反旋转以及安装液压系统控制车箱延长收缩都是本发明的技术特征。包括三轮车前轮设置动力,由三轮车型设计预备轮成五轮车型都能尽量发掘车辆潜在资源,本发明很有推广实用价值。
