【Detailed ways】

The present invention will be further described below in conjunction with accompanying drawing:

As shown in Figures 1 to 3, a stroller can move from an unfolded position to a folded position, comprising:

The front frame 1 is connected with the front wheel 101;

Rear vehicle frame 2, is connected with rear wheel 201 on it;

An active rod 3, one end of which is hinged on the upper part of the front frame 1, and the other end cooperates with the rear frame 2 and can slide along the rear frame 2 during the unfolding or folding process of the stroller;

A backrest bar 4, the middle of which is connected with a side armrest 5 with one end hinged to it and the other end hinged to the upper part of the front frame 1;

Rear longitudinal rod 6, one end of which is hinged on the rear frame 2, and the other end is hinged on the lower part of the backrest rod 4;

Front longitudinal bar 7, one end of which is hinged in the middle of front frame 1, and the other end is hinged in the lower part of backrest bar 4;

Linkage rod 8, one end of which is hinged on the upper part of the front frame 1, and the other end is hinged on the rear longitudinal rod 6;

A locking device 9 that keeps the stroller in an unfolded state when locked and can push the backrest bar 4 to complete the folding of the stroller after unlocking.

The backrest bar 4, the rear longitudinal bar 6 and the front longitudinal bar 7 are coaxially hinged.

After the locking device 9 is unlocked and pushes the backrest bar 4 forward, the front frame 1 is pulled by the front longitudinal bar 7 and rotates backwards, and the rear end of the movable bar 3 is slidably matched with the rear frame 2 and moved in the rear frame 2. Shrink, the front longitudinal bar 7, the rear longitudinal bar 6, the linkage bar 8, and the backrest bar 4 all rotate to complete the folding of the stroller.
