Description

Technical Field

[0001] The utility model relates to the technical field of electric tricycles, in particular to an electric tricycle with a trailer structure. Background Art

[0002] In the prior art, an electric tricycle is a three-wheeled transport tool for pulling goods or people, which is powered by a battery and driven by a motor. The electric tricycle adopts a tubular large-capacity, left and right lining, deep discharge, and traction battery, which can meet the requirements of long-term continuous discharge. The electric tricycle has the advantages of strong applicability, flexibility, simple maintenance, convenient repair, and low price, and can flexibly travel between narrow roads. The electric tricycle has a reversing switch, which can conveniently realize the reverse and forward driving function, which is very practical in narrow alleys and lanes. It is very convenient to drive and park, and is widely used in short-distance transportation fields such as families, urban and rural areas, individual rentals, factory areas, mining areas, sanitation, and community cleaning. Existing household electric tricycles usually only have the function of carrying people, and can store some small-volume items to meet the small-range traffic needs in daily family life, but they cannot transport large-volume items or large quantities of items. For example, when picking up express delivery, it is impossible to store and transport a variety of large-volume items, and has certain usage restrictions.
