A handle 9 is connected to the upper part of the handle bar 2. The folding stroller has an unfolded state and a folded state, when the folding stroller is in the unfolded state, the handle bar 2, the front fork bar 3, the connecting rod 5, and the rear wheel support bar 4 are all unfolded with respect to the frame rail 1, and preferably, the axis of the handle bar 2 coincides with the axis of the front fork bar 3, and when the folding stroller is in the folded state, the handle bar 2, the front fork bar 3, the connecting rod 5, and the rear wheel support bar 4 are all drawn close to the frame rail 1, and preferably, the front wheel assembly 6 is drawn close to the rear of the frame rail 1, and the rear wheel 7 is drawn close to the front of the frame rail 1.

Specifically, the frame cross bar 1 is connected with a sliding block 8 in a sliding manner, and one ends of the two connecting rods 5 are both connected to the sliding block 8 in a rotating manner.

In a more preferred embodiment, the first gear 11 is fixedly connected to the lower portion of the handlebar 2, the second gear 12 is fixedly connected to the upper portion of the front fork 3, the first gear 11 and the second gear 12 are both rotatably connected to the frame rail 1, and the first gear 11 and the second gear 12 are meshed. Thus, when the baby carrier is folded, only one of the handle bar 2 and the front fork bar 3 is required to be rotated, the other can be rotated in linkage therewith, and after the baby carrier is folded, only one of the handle bar 2 and the front fork bar 3 is required to be locked with the position of the frame cross bar 1, and then the other is also locked with the position.

In the present embodiment, a locking structure is provided that is capable of locking the position of one of the handle bar 2 and the front fork 3 to the frame rail 1 after the folding of the stroller is completed. Specifically, the handle bar 2 or the front fork bar 3 is provided with a latch hook 19, in this embodiment, the latch hook 19 is disposed on the handle bar 2, the slider 8 is provided with a latch groove (labeled in the drawing), and when the folding stroller is in a folded state, the latch hook 19 is connected with the latch groove, and the structure locks the positions of the handle bar 2 and the front fork bar 3, and simultaneously locks the positions of the rear wheel support bar 4 and the connecting rod 5, so that the folding stroller is integrally kept in a folded state.

The front portion of the frame rail 1 has a base 10, the base 10 being pivotally connected to the frame rail 1 by a pivot axle 15, the handlebar 2 and the front fork 3 being pivotally connected to the base 10. The first gear 11 and the second gear 12 described above are both rotatably connected inside the base 10. Preferably, the axis of the rotary shaft 15 coincides with the axis of the handle bar 2 and the axis of the front fork 3.

A first locking mechanism for locking the relative positions of the handle bar 2, the front fork bar 3 and the base 10 when the folding baby carrier is in an open state is arranged between the handle bar 2 and the base. In the present embodiment, a specific structure of the first locking mechanism is given, which includes a latch 16 connected to the handle bar 2 and the front fork 3, respectively, and a locker 17 rotatably connected to the base 10 and capable of being connected to and disconnected from the latch 16. The locking piece 17 is provided with a buckle 20, when the first locking mechanism is locked, the buckle 20 hooks the clamping block 16, and when the operation is unlocked, the buckle 20 is separated from the clamping block 16 by rotating the locking piece 17.
