Detailed ways

As shown in the accompanying drawings, a stroller for children includes a stroller frame 1 with an unfolded position and a folded position, a front wheel assembly 2 arranged at the bottom front of the stroller frame 1 , The rear wheel assembly 3 at the bottom rear part, the frame locking mechanism for locking the cart frame 1 in the unfolded position, and the human body accommodation device arranged on the cart frame 1 . Not shown in the figure, the human body receiving device can be a child's seat pocket, or a child's sleeping basket, etc., and the installation method can also be fixed on the stroller frame 1, or can be detachably installed on the stroller frame 1 .

As shown in the accompanying drawings, the cart frame 1 includes

first bracket 11;

The push rod frame 12, the bottom of the push rod frame 12 is rotationally connected with the top of the first bracket 11 through the first rotating shaft 21;

The second support 13, the top of the second support 13 is rotationally connected with the push rod frame 12 through the second rotating shaft 22, and the second rotating shaft 22 is positioned above the first rotating shaft 21;

Seat frame 14, the front portion of seat frame 14 is connected with the first support 11 by the 3rd rotating shaft 23 rotatably, and the 3rd rotating shaft 23 is positioned at the below of first rotating shaft 21, and the rear portion of seat frame 14 and the bottom of second support 13 Rotately connected through the fourth shaft 24;

Shock-absorbing link 15, one end of the shock-absorbing link 15 is rotatably connected with the rear portion of the seat frame 14 or the bottom of the second support 13, as, between the shock-absorbing link 15 and the seat frame 14 can be There are two rotating shafts, and they can also share a rotating shaft to be connected in rotation. In this embodiment, one end of the shock-absorbing link 15 is connected in rotation to the lower part of the second bracket 13 through the seventh rotating shaft 27, and the seventh rotating shaft 27 located below the fourth rotating shaft 24;

Underframe 16, the front portion of underframe 16 is connected with the bottom of first bracket 11 through the fifth rotating shaft 25 to rotate, and the fifth rotating shaft 25 is positioned at the below of the third rotating shaft 23, and the rear portion of underframe 16 is connected with the shock-absorbing connecting rod The other end of 15 is rotatably connected by a sixth rotating shaft 26,

The rotational connection between one end of the shock absorber link 15 and the rear part of the seat frame 14 or the lower part of the second bracket 13 is located between the fifth rotating shaft 25 and the sixth rotating shaft 26 .

The first bracket 11 , the push rod frame 12 , the second bracket 13 and the seat frame 14 constitute a four-bar linkage mechanism, and the vehicle frame locking mechanism is arranged at the rotational connection of any two adjacent links of the four-bar linkage mechanism.
