In this way, the purpose of rotating the link 4 relative to the front leg 6 is achieved.

Preferably, the opposite sides of the left and right front legs 2 are respectively provided with an assembling portion 21 in a protruding manner, the opposite sides of the assembling portion 21 are respectively provided with a receiving hole (not shown), and the left and right sides of the pivot rod respectively extend into the receiving holes of the assembling portions 21 of the left and right front legs 2; the baby carriage further comprises a pivoting piece, the pivoting piece comprises a pivoting part 71 which is sleeved on the pivoting rod 6 in a relatively rotating manner and a connecting part 72 which extends from the pivoting part 71 to one side, and the lower side of the linkage piece 4 is connected with the connecting part 72; the left and right ends of the pivoting portion 71 respectively abut against the opposite sides of the assembling portions 21 of the left and right front legs 2. By the arrangement, the left and right movement of the pivot joint part can be avoided, so that the stability of the baby carriage in the unfolding state is ensured.

In this embodiment, the connecting portion 72 is provided with a connecting hole, and the lower side of the link 4 is connected to the connecting hole, so that the assembly is more convenient.

In this embodiment, the linkage member 4 includes two left and right linkage rods 41, and correspondingly, the pivoting portion 71 extends to form two connecting portions 72, and the lower sides of the two linkage rods 41 are respectively connected to the connecting holes of the two connecting portions 72; the seat support 3 includes two left and right support rods 31; the rear sides of the left and right support rods 31 are pivoted to the driver 1, and the front sides are respectively pivoted to the upper sides of the left and right linkage rods 41.

Specifically, the specific shape and number of the seat support 3 and the link 4 are not the point of the present invention.

In this embodiment, the stroller of the present invention is provided with the left and right rear legs 5. In other embodiments, the stroller according to the utility model can also be provided with a front leg 2 or/and a rear leg 5. The specific number can also be set as desired.

Preferably, the lower side of the rider 1, the rear side of the front leg 2 and the front side of the rear leg 5 can be coaxially pivoted, so that the assembly is more convenient. In other embodiments, the underside of the rider 1, the rear side of the front leg 2, and the front side of the rear leg 5 may not be pivotally connected.

The handle 1 is rotated forward and downward, due to the characteristic of the four-bar linkage structure, the seat support 3 is also driven to move forward and downward and rotate, so that the front side of the seat support 3 can push the upper side of the linkage 4 to move forward and downward (as shown in fig. 3 and 4) until the handle 1 can not rotate any more, and the rear foot 5 can also rotate forward relatively and approach the front foot 2 until the rear foot 5 can not rotate any more, at the moment, the baby carriage is completely folded, the handle 1, the front foot 2, the seat support 3 and the linkage 4 approach each other, and the rear foot 5 also approaches the front foot 2 (as shown in fig. 5 and 6), so that the folded baby carriage is small in volume and convenient to carry and store.

When the push handle 11 and the handle 1 are in the unfolded state, the total height of the push handle 11 and the handle 1 is suitable for a caregiver; when the baby carriage needs to be folded, the push handle 11 is moved downwards relative to the hand 1 until the baby carriage can not move any more, so that the overall height of the folded baby carriage is reduced, namely the overall volume of the folded baby carriage is reduced, and the overall volume of the folded baby carriage is small.

In other embodiments, the pushing handle 11 may be pivoted to the upper side of the rider 1 at the lower side. Similarly, when the push handle 11 and the handle 1 are in the unfolded state, the total height of the push handle 11 and the handle 1 is suitable for a caregiver, and when the stroller needs to be folded, the push handle 11 is rotated downward to be close to the handle 1, so that the total height of the folded stroller frame can be prevented from being affected, and the folded stroller has a small volume.

The connection between the handle bar 11 and the handle bar 1 may be any known and feasible structure, and is not the utility model point of the present invention, and therefore, is not described herein.

The front lower part of the front foot 2 is connected with a front wheel 20, and the rear lower part of the rear foot 5 is connected with a rear wheel 50.

As shown in fig. 9, the stroller of the present invention further comprises a seat 8, wherein the seat 8 is connected to the seat support 3, so that the seat 8 can move and rotate with the seat support 3 when the stroller is folded.

The seat 8 comprises a supporting portion 81 and a backrest 82 with a lower side pivoted to the supporting portion 81, the supporting portion 81 is connected to the seat support 3; alternatively, the seat support 3 is configured as a support for the seat 8, and the seat further comprises a backrest 82, wherein the lower side of the backrest 82 is pivotally connected to the seat support 3.

When the stroller of the present invention is folded, the backrest 82 can be rotated to be close to the supporting portion 81/the seat supporting member 3 (as shown in fig. 10), so as to reduce the volume of the folded seat 8, and thus the overall volume of the folded stroller.

In the above orientation definition, the front wheel 20 is located at the front, the rear wheel 50 is located at the rear, the two front legs 2 are located at the left and right, the rider 1 is located at the upper, and the front wheel 20 and the rear wheel 50 are located at the lower.
