Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, 2 and 3, the foldable stroller of the present invention comprises an upper frame 10, a lower frame 20, two rotating joints 30 and two locking mechanisms for unlocking by pulling.

The two sides of the upper frame 10 are connected with the two sides of the lower frame 20 through two rotating joints 30, each rotating joint 30 has two joints which can rotate relatively, the upper frame 10 and the lower frame 20 are connected to the two joints respectively, so that the upper frame 10 and the lower frame 20 can rotate relatively through the rotating joints 30, the two locking mechanisms are connected with the two rotating joints 30 respectively, the two locking mechanisms are used for locking or unlocking the two rotating joints 30 respectively, when the rotating joints 30 are in a locking state, the upper frame 10 and the lower frame 20 are fixed relatively, and when the rotating joints 30 are in an unlocking state, the upper frame 10 and the lower frame 20 can rotate relatively.

The upper frame 10 comprises a push rod handrail 11, an upper supporting rod 12, a lower supporting rod 13, a front blocking rod 14, a sunshade supporting rod 15 and two first connecting pieces 16, wherein the push rod handrail 11, the upper supporting rod 12, the lower supporting rod 13, the front blocking rod 14 and the sunshade supporting rod 15 are all U-shaped, the upper supporting rod 12 and the lower supporting rod 13 are used for fixing a seat of the baby carriage, the front blocking rod 14 is positioned in front of the upper supporting rod 12 and used for preventing the baby from falling forwards when sitting on the seat, the sunshade supporting rod 15 is positioned in front of the upper supporting rod 12 and used for fixing a sunshade, two ends of the sunshade supporting rod 15 are respectively hinged with two sides of the upper supporting rod 12, two ends of the lower supporting rod 13 and two ends of the front blocking rod 14 are respectively hinged with the two first connecting pieces 16, two ends of the push rod 11 are respectively fixedly connected with the two first connecting pieces 16, and the two first connecting pieces 16 are respectively connected with the two rotating joints 30, thus, when the stroller is folded, the upper support rod 12, the lower support rod 13, the front stop rod 14, and the sunshade support rod 15 can be folded on the armrest push rod 11 by rotation.

The lower frame 20 includes two second connecting members 21, two rear leg rods 22 and two front leg rods 23, the two second connecting members 21 are respectively connected to the two rotating joints 30, so that the two second connecting members 21 are respectively rotatably connected to the two first connecting members 16 through the rotating joints 30, that is, the first connecting members 16 and the second connecting members 21 are respectively connected to the two joints of the rotating joints 30, the two rear leg rods 22 are respectively connected to the two second connecting members 21, and the two front leg rods 23 are respectively hinged to the two second connecting members 21, so that when the stroller is folded, the front leg rods 23 and the rear leg rods 22 can be relatively folded through rotation.

The locking mechanism includes an unlocking switch 41 capable of being pulled, a movable member 42 driven by the unlocking switch 41 to move, a tension spring 43 connected with the movable member 42, and a lock pin 44 connected with the tension spring 43, when the locking mechanism is unlocked, the unlocking switch 41 is pulled, the unlocking switch 41 drives the movable member 42 to move, and the movable member 42 drives the lock pin 44 to move through the tension spring 43, so that the lock pin 44 unlocks the rotary joint 30.
