Description

Technical Field

[0001] The utility model relates to the field of baby carriages, in particular to a folding structure and a baby carriage. Background Art

[0002] A baby stroller usually includes a main body, a seat, a sunshade and rollers, etc. The main body can be divided into a plurality of relatively foldable components, so that the baby stroller can be unfolded when needed and folded and stored when not needed. However, in existing baby strollers, the trigger mechanism of the folding structure is a pull button or a knob. When folding, the user needs to pull the pull button to the unlocking position or turn the knob to the unlocking position, and then unlock the joints of the baby stroller to complete the folding of the baby stroller. When folding, the baby stroller with this structure not only needs to bend over to operate, but also the unlocking operation is relatively complicated, which causes certain inconveniences when using it. Therefore, a new folding structure and a baby stroller are urgently needed to solve the above problems. Utility Model Content

[0033] Reference Figures 1 to 4 , a folding structure, comprising a frame 10, an armrest frame 20, a first locking assembly 30 and a second locking assembly 40;

[0034] The armrest frame 20 includes a connecting frame 21 and a push handle 22. One end of the connecting frame 21 is rotatably connected to the frame 10, and the push handle 22 is movably arranged on the other end of the connecting frame 21.

[0035] The first locking assembly 30 is connected between the push handle 22 and the connecting frame 21, and is used to limit the relative movement between the push handle 22 and the connecting frame 21;

[0036] The second locking assembly 40 is connected between the connecting frame 21 and the frame 10 to limit the relative movement between the connecting frame 21 and the frame 10;

[0037] The push handle 22 can move along the connecting frame 21 toward the frame 10 when the first locking assembly 30 is in the unlocked state, and trigger the second locking assembly 40 to enter the unlocked state, so that the armrest frame 20 can be folded relative to the frame 10 .

[0038] In the utility model, the baby carriage is composed of Figure 1-2 The expanded state of Figure 3 The folded state is taken as an example to illustrate, specifically:

[0040] In the stroller Figure 1-2 When the connecting frame 21 is in the expanded state, the limiting member 42 at least partially extends into the limiting groove of the connecting frame 21 under the action of the second restoring member. At this time, another part of the limiting member 42 contacts the frame 10, thereby limiting the relative movement between the connecting frame 21 and the frame 10.

[0041] ② When the baby carriage needs to be folded, the first locking assembly 30 is first unlocked, so that the push handle 22 can move relative to the connecting frame 21. When the push handle 22 moves toward the direction of the frame 10 to the bottom of the connecting frame 21, it will abut against the movable seat 41. In the further movement, the movable seat 41 will be driven to move, and the movable seat 41 will push the driving member 43 to enter the unlocking position. Specifically, the driving member 43 is pushed to rotate. When the driving member 43 rotates, the first push arc surface 61 and the second push arc surface 62 cooperate to drive the limiting member 42 to move. Specifically, the limiting member 42 is driven to disengage from the limiting groove on the connecting frame 21, thereby releasing the restriction on the connecting frame 21, so that the connecting frame 21 can be rotated and folded relative to the frame 10;

[0042] It should be noted that a receiving groove 70 adapted to the limiting member 42 is provided on the frame 10, which is used to provide a receiving space for the limiting member 42 when the driving member 43 drives the limiting member 42 to disengage from the limiting groove; the limiting member 42 is configured to be gear-shaped, and the limiting groove and the receiving groove 70 are both configured to be gear grooves adapted to the limiting member 42, and the rotation limit is achieved through the cooperation of the toothed structure.

[0044] In a further embodiment, a folding structure further includes a guide wheel 50 rotatably disposed on the connecting frame 21, and the traction rope is wound around the guide wheel 50; the guide wheel 50 is provided to provide a guiding or smoothing effect for the movement of the traction rope.

[0045] ④The advantage of the utility model is that the one-touch quick unlocking between the frame and the armrest is performed through the above-mentioned structure, which not only realizes the rapid folding of the baby stroller, but also does not require the user to bend over to operate, greatly improving the folding experience of the baby stroller and having very good practicality.

[0046] Preferably, a first abutting arc surface 61 is provided on the driving member 43 , and a second abutting arc surface 62 abutting against the first abutting arc surface 61 is provided on the limiting member 42 .

[0047] A folding structure further includes a first restoring member disposed between the movable seat 41 and the connecting frame 21 , and further includes a second restoring member disposed between the limiting member 42 and the frame 10 .

[0048] As a preferred embodiment of the first restoring member and / or the second restoring member, the first restoring member and / or the second restoring member is configured as a restoring spring.
