In this embodiment, preferably, the first connecting member 2 'includes a first section 21' extending from bottom to top in an inclined manner and a second section 22 'extending from a lower end of the first section 21' to top, an upper side of the first section 21 'is rotatably connected to the handle bar 1 around the rotating shaft six 11, and a rear side of the second connecting member 6' is rotatably connected to a front side of the second section 22 'around the rotating shaft five 62'. Preferably, the positions of the first rotating shaft 41 ', the fifth rotating shaft 62 ' and the sixth rotating shaft 11 ' are distributed in a triangle. The rear leg 4 may be rotatably connected to the first section 21 'of the first connecting member 2', may be rotatably connected to the second section 22 'of the first connecting member 2', or may be rotatably connected to a connecting position of the first section 21 'and the second section 22', but the rear side of the second connecting member 6 'is not coaxially and rotatably connected to the first connecting member 2' and the rear leg 4. That is, the rear side of the second connecting member 6 ' is rotatably connected to the first connecting member 2 ', and the second connecting member 6 ' is configured such that the rear side thereof is not coaxially and rotatably connected to the first connecting member 2 ' and the rear leg 4, in the embodiment, the first rotating shaft 41 and the fifth rotating shaft 62 ' cannot be the same shaft.
The first section 21 'and the second section 22' may be integrally formed, or may be two components fixedly connected to each other.
Because the utility model stroller frame 10 'in this embodiment adopts the above structure, when the stroller frame 10' is to be folded, similarly, only the lower side of the push handle 1 is rotated and moved towards the direction of the rear foot 4 towards the rear lower side, and simultaneously the upper side of the push handle 1 is rotated forwards, due to the characteristics of the four-link structure, the first link 2 '(i.e. the upper side of the first vertical rod first section 21') and the rider 3 can be easily driven to rotate and move towards the rear foot 4 towards the rear lower part, while the lower front side of the first connecting member 2 '(i.e. the front side of the second section 22' of the first connecting member 2 ') pulls the rear side of the second connecting member 6' to rotate relatively upward and rearward, so that the front foot 5 can rotate towards the direction of the rear foot 4 under the driving of the front side of the second connecting piece 6' (the front foot 5 still uses the third rotating shaft 43 as the rotating shaft when rotating) (as shown in fig. 8); until the push handle 1, the driver 3, the first connecting piece 2 ', the second connecting piece 6' and the front foot 5 are close to the rear foot 4, the framework is completely folded (as shown in figures 9 and 10). Thus, when the stroller framework 10 'of the present embodiment is folded, only the lower side of the push handle 1 is required to rotate toward the rear lower side toward the rear leg 4, and the upper side of the push handle 1 is required to rotate forward, other components of the stroller framework 10' can be easily and smoothly linked to rotate to approach each other, so that the folding operation is labor-saving, and the folding burden of parents holding a child can be reduced; moreover, because the stroller frame 10' is completely folded, the components thereof are relatively close to each other, so that the overall volume of the folded stroller frame 10 is small, and the stroller frame is convenient to store and carry. And because the positions of the first rotating shaft 41 ', the fifth rotating shaft 62' and the sixth rotating shaft 11 'are distributed in a triangular manner, when the upper side of the first connecting piece 2' rotates backwards and downwards, the front lower side of the first connecting piece 2 'can drive the rear side of the second connecting piece 6' to move backwards by a larger distance, so that the front foot 5 can be pulled to rotate backwards by a larger angle, namely, the front foot 5 can be closer to the rear foot 4, and the size of the folded framework can be smaller.
