Description

CROSS REFERENCE TO RELATED APPLICATIONS The present application claims the benefit of Chinese Patent Application No. 202223168040.6 filed on Nov. 28, 2022, the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD The present invention relates to the technical field of camping vehicles, and particularly relates to a manned folding pedal of an outdoor foldable electric trailer. BACKGROUND Carts for outdoor activities, also known as camp trailers, camping trailers, camper trailers, etc., are usually used to transport outdoor equipment (such as energy storage power supplies, outdoor refrigerators, tents, catering equipment, food, communication equipment, etc.) from indoors or vehicles to event destinations during outdoor activities. The design of a folding structure of vehicle body enables convenient unfolding, storage and transportation without taking up too much storage space. Existing outdoor trailers cannot carry people, and need to be dragged by manpower or electric power, or pushed to move. Also, the user needs to control the distance from the trailer to avoid collisions. In particular, collisions between the trailer and the user are very likely to occur due to fast speeds of moving on downhill roads.
