Description

Technical Field

[0001] The utility model relates to the technical field of bicycle child seats, in particular to a portable bicycle child seat. Background Art

[0002] A bicycle child seat is a seat installed on the back seat of a bicycle. A child can be placed inside the bicycle child seat while riding a bicycle, and the bicycle child seat can be used to carry the child.

[0003] The existing bicycle child seat is usually composed of a bottom plate, a backrest plate, armrests, a rubber pad and a mounting seat. The main body is welded from steel pipes or steel plates, which makes the bicycle child seat larger in size and inconvenient to fold. The larger bicycle child seat is not convenient to carry and transport. At the same time, when the child sits in the child seat, the back of the child is pressed against the backrest plate, which makes the child's back sweat easily, especially in summer or when the temperature is high, which affects the comfort of the portable bicycle child seat when used. Therefore, we propose a portable bicycle child seat. Utility Model Content

[0004] The purpose of the utility model is to provide a portable bicycle child seat to solve the problems of the bicycle child seat proposed in the above background art, such as the large overall volume and the child's back being pressed against the backrest, which makes the child sweat easily in summer.
