Description

Technical Field

[0001] The utility model belongs to the technical field of children's tricycles, and in particular relates to a foldable and flat-lying children's tricycle. Background Art

[0002] A tricycle refers to a vehicle with three wheels. The main structure of a three-wheeled electric vehicle includes the front of the vehicle, the connection pedals, the seat, and the entire rear frame. In the past, tricycles usually had the entire main structure pre-welded and then packaged for transportation, that is, the front of the vehicle was welded to the connection pedals, the seat was welded to the connection pedals, and the entire rear frame was welded to the seat. This type of tricycle takes up more space for transportation, and the entire frame and seat occupy a large space before and after. For transportation, unusable space means waste, which increases transportation costs. Moreover, for modified vehicles, usually, the original factory transports the tricycle to the modification factory, and then the modification factory transports it to the customer. The transportation cost in between is relatively high. During transportation, if the space occupied by a tricycle can be reduced, the transportation cost can be reduced.

[0003] Currently, the existing foldable and reclining children's tricycle lacks the function of adjusting the backrest angle. The lack of the backrest angle adjustment function may cause children to be unable to adjust the seat angle according to their own needs and comfort during riding, reducing the riding comfort. The fixed-angle backrest may not meet the needs of children of different heights, body shapes and preferences, limiting the children's options for adjusting their body posture during riding. The lack of an adjustable reclining function in the children's tricycle will affect the rest and sleep experience of children while riding, and cannot provide a suitable reclining posture. Utility Model Content
