The front lower end of the front leg; the rear end of the arc-shaped bottom bar is rotatably connected to the rear part of the rear rocker, and the front part of the rear rocker is rotatably connected to the rear lower end of the rear leg; the arc-shaped The front part and the rear part of the bottom bar are respectively connected with a front wheel and a rear wheel which can be flipped up; rotatably connected, the lower part of the front leg can also be rotatably connected to the front end of the blue frame; the lower part of the hand push rod is rotatably connected to the upper end of the second connecting rod, and the lower end of the second connecting rod It is rotatably connected to the middle part of the rear leg, one end of the first connecting rod is rotatably connected to the blue frame, and the other end of the first connecting rod is rotatably connected to the rear leg or the second connecting rod.

本实用新型与现有技术相比具有下列优点：Compared with the prior art, the utility model has the following advantages:

前腿为一根完整的杆件，使得它有较少的塑料连接件，在折叠过程中干涉件少，前腿便于与车体一起进行整体造型设计。整个车架折叠及打开时杆件相互干涉少，利于折叠及打开平稳安全，当前轮和后轮向上翻转使得弧形底杆着地后，本实用新型可作为摇蓝车使用。在车架打开时，车架能在受力时微微摆动，使得前摆件与后摆件具有避震作用。The front leg is a complete rod, so that it has fewer plastic connecting parts, less interference parts during the folding process, and the front leg is convenient for the overall shape design with the car body. When the entire vehicle frame is folded and opened, there is little interference between the rods, which is conducive to stable and safe folding and opening. After the front and rear wheels are turned up so that the arc-shaped bottom bar touches the ground, the utility model can be used as a blue car. When the vehicle frame is opened, the vehicle frame can swing slightly when stressed, so that the front and rear pendants have a shock-absorbing effect.
