The buggy further comprises a seat 10 provided on the frame, which seat 10 is mounted on the rear frame 2.
Referring to the drawings, in the embodiment, the front wheel rod 3 comprises a first front wheel rod 31 and a second front wheel rod 32 which are connected in a sliding and telescopic manner along the left-right direction, and two front wheels 8 are respectively and rotatably arranged on the outer end parts of the first front wheel rod 31 and the second front wheel rod 32; the rear wheel lever 4 includes a first rear wheel lever 41 and a second rear wheel lever 42 telescopically connected to slide in the left-right direction, and two rear wheels 9 are rotatably mounted on outer end portions of the first rear wheel lever 41 and the second rear wheel lever 42, respectively. Here, the first front wheel rod 31 is slidingly sleeved on the second front wheel rod 32, and the first front wheel rod 31 is slidingly connected to the bottom front part of the front frame 1 along the length direction thereof; the first rear wheel rod 41 is slidably sleeved on the second rear wheel rod 42, and the first rear wheel rod 41 is slidably connected to the bottom rear part of the rear frame 2 along the length direction thereof.
Referring to the drawings, the frame further includes an operating lever 6 rotatably connected at a lower portion thereof to a front portion of the front frame 1, and a connecting rod 7 rotatably connected at one end portion thereof to the operating lever 6 and at the other end portion thereof to the rear frame 2. When the control rod 6 rotates downwards to draw in the front frame 1, the connecting rod 7 is driven to rotate to draw in the rear frame 2, meanwhile, the front frame 1 and the rear frame 2 extend along the front-rear direction, the distance between the front wheel rod 3 and the rear wheel rod 4 along the front-rear direction is gradually increased, the two connecting rods 5 rotate relatively, the front wheel rod 3 and the rear wheel rod 4 slide and contract along the left-right direction, the distance between the front wheels 8 on the two sides and the distance between the rear wheels 9 on the two sides are respectively reduced.
The baby carriage also comprises a locking mechanism for locking the baby carriage in the unfolding state, and when the baby carriage is specifically arranged, the locking piece can be used for locking the front frame 1 and the rear frame 2 of the main frame relatively, so that the whole baby carriage can be locked.
In summary, when the stroller is locked in the unfolded state, as shown in fig. 1 to 4, the operating lever 6 is unfolded with respect to the main frame so as to be inclined upward from the front to the rear, and the child seated on the seat 10 operates the operating lever, the two links 5 are unfolded in the left-right direction so that the front wheel bar 3 and the rear wheel bar 4 are extended in the left-right direction, and the two sets of front wheels 8 and the two sets of rear wheels 9 are unfolded with respect to the main frame.
When the baby carrier needs to be folded, after the locking mechanism is unlocked, the operating rod 6 is pressed downwards to rotate and fold towards the main frame, the front frame 1 and the rear frame 2 slide and extend relatively along the front-back direction, so that the distance between the front wheel rod 3 and the rear wheel rod 4 along the front-back direction is gradually increased, the two connecting rods 5 are driven to rotate relatively, the front wheel rod 3 and the rear wheel rod 4 slide and contract along the left-right direction, and the distance between the front wheels 8 on the two sides and the distance between the rear wheels 9 on the two sides are respectively reduced. As shown in figure 5, the operating rod 6, the connecting rod 7 and the main frame of the folded baby carrier are folded up along the vertical direction, the front frame 1 and the rear frame 2 are relatively extended, the two groups of front wheels 8 and the two groups of rear wheels 9 are folded up at the left side and the right side of the main frame, and the whole width of the baby carrier is greatly reduced. The whole baby carriage is very flat and compact in structure, and brings convenience for storage, transportation, daily storage, carrying and the like.
When the baby carriage needs to be unfolded, the whole baby carriage can be unfolded only by pulling the operating rod 6 upwards and pressing the main frame downwards, and the unfolding operation is very convenient.
