Description

Technical Field

[0001] The present application relates to the technical field of electric bicycles, and in particular to an electric bicycle that is convenient for splicing with a camping vehicle. Background Art

[0002] With the increasing popularity of camping activities, consumers' demand for camping vehicles that can be carried flexibly and provide resting space at any time has increased dramatically. Electric bicycles, with their environmental protection, energy saving and convenient travel characteristics, have become one of the ideal choices for towing camping vehicles.

[0003] However, in the prior art, the design of a camper usually includes a cargo box for loading items, stable wheels, and a tow bar for connection, which together constitute a complete towing system. When it is necessary to connect the camper with an electric bicycle for towing, a key step is to connect the tow bar on the camper with a fixed point on the rear of the electric bicycle.

[0004] In this process, the traditional method is to use a towing rope to tie the end of the towing rod to the rear seat of the electric bicycle. However, this method has exposed some problems in actual operation: for non-professional users, the tightening process of the towing rope may be complicated and prone to errors. If it is improperly tied, it may not only affect the stability of the towing, but also pose a safety hazard to the normal driving of the electric bicycle. Therefore, there is significant room for improvement in this link. Utility Model Content
