Wherein, the adapter 400 further comprises an operation member 430 rotatably connected to the second arm 420, a locking member 440 rotatably connected to the operation member 430, the locking member 440 having:

A locked state, interacting with the first clasping arm 410 to hold the first clasping arm 410 and the second clasping arm 420 in a first state;

The released state is released from the interaction with the first clasping arm 410 under the driving of the operation member 430, so that the first clasping arm 410 and the second clasping arm 420 are in the second state. Compared with the prior art, the adapter 400 of the bearing device 3000 is directly sleeved on the push handle assembly 130 to realize connection, so that the structure of the side frame 100 is simplified.

Referring back to fig. 5-7, in one embodiment, in the unfolded state of the child carrier 1000, the side rails 133 are substantially 90 degrees from the rear legs 121, and the bottom frame 320 extends along a horizontal plane and is substantially 40 degrees from the side rails 133. When folded, the side rails 133 are approximately 10 degrees from the rear leg 121 and the bottom frame 320 is approximately parallel to the rear leg 121, the angle being set to minimize the rotational amplitude setting described above.

Referring to fig. 5 and 16-18, with respect to the carrying device 3000, in one embodiment, the side frames 330 drive the top and bottom frames 310, 320 to be aligned together when folded, and the side frames 330 drive the top and bottom frames 310, 320 to be aligned apart when unfolded.

The carrying device 3000 further comprises a connecting seat 340 and a driving member, wherein the connecting seat 340 is used for connecting the two side frames 330, and is slidably mounted on the bottom frame 320 and has a first position and a second position on the sliding path, and when the connecting seat 340 slides between the two positions, the corresponding side frames 330 are switched between the folded state and the unfolded state. The driving member is used to drive the connecting seat 340 to slide from the first position to the second position to deploy the side frame 330. The illustrated side frames 330 are:

the side frame 330 includes a plurality of first side bars 331, and each of the first side bars 331 is inclined in the same direction, for example, the top frame 310 and the bottom frame 320 form an included angle. For example, the top frame 310 and the bottom frame 320 are parallel to each other in the illustration, and then the first side bars 331 are parallel to each other, and the connection seat 340 is connected to all the first side bars 331 to realize synchronous movement of the first side bars 331, so as to ensure that the side frames 330 on both sides can be folded or unfolded synchronously. Further, the side frame 330 further includes a second side bar 332, one end of the second side bar 332 is hinged to the first side bar 331, the other end is hinged to the bottom frame 320, and the inclination directions of the second side bar 332 and the first side bar 331 are opposite, so as to improve the structural stability of the support frame 300 in the unfolded state.

In actual operation, when the supporting framework 300 is in the folded state, the operation driving member drives the connecting seat 340 to move along the first direction, the upper portion of the first side bar 331 moves upwards to drive the top frame 310 away from the bottom frame 320 until the supporting framework 300 is in the unfolded state, and when the supporting framework 300 is folded, the top frame 310 is pressed downwards to enable the connecting seat 340 to slide along the second direction until the supporting framework 300 is in the folded state. Compared with the prior art, the unfolding operation is more convenient.

The carrying device 3000 further comprises a cloth bag 370 connected between the top frame 310 and the bottom frame 320 and wrapping the side frames 330, and in the unfolded state, the cloth bag 370 pulls the top frame 310 and the bottom frame 320 so that the supporting framework 300 is unfolded to the maximum height, thereby indirectly limiting the connection seat 340 to continue moving along the pulling direction.

The connection seat 340 may be a frame formed by a cross bar or a plurality of rods, or a part sleeved on the bottom frame in a sliding manner, etc. For example, as shown in fig. 16, in one embodiment, the connecting seat 340 is a frame structure, and includes two cross bars 341 corresponding to two pairs of first side bars 331, and at least one longitudinal bar 342 connected between the two cross bars 341, where two ends of the cross bars 341 are slidably engaged with the bottom frame 320, and the two side frames 330 are hinged to the connecting seat 340, for example, one pair of first side bars 331 symmetrically arranged in the two side frames 330 is hinged to one of the cross bars 341, and the other pair of first side bars 331 is hinged to the other cross bar 341. For another example, the connection seat 340 includes a slider slidably engaged with the bottom frame 320 and a cross member connecting the two sliders, and the first side bar 331 on the same side is hinged to the slider.

Further, the carrying device 3000 further comprises a locking device 360 for locking the supporting framework 300 in the unfolded state, and the locking may be provided between the connection seat 340 and the bottom frame 320, i.e. locking the connection seat 340.

In some embodiments, the locking device 360 achieves locking by limiting the movement of the driving member, it being emphasized that the object of action of the locking device 360 is the driving member. Specifically, the driving member is a flexible member 350, the flexible member 350 is configured to expand the supporting frame 300 by pulling the connecting seat 340, and the flexible member 350 is a belt or a wire or a combination of two shapes, such as a nylon webbing or a steel wire, or a combination of two types, etc. When the carrying device of the application is unfolded, the locking device 360 acts on the corresponding position of the flexible piece 350 to keep the supporting framework 300 in an unfolded state all the time, so that safety accidents caused by folding due to incomplete locking are avoided.

The flexible member 350 has a fixed end 351 and an operating end 352, the operating end 352 is exposed outside the supporting frame 300, and the length of the operating end 352 exposed outside the supporting frame 300 is increased during the stretching operation. The connection relationship between the flexible member 350 and the connection base 340 adopts at least one of the following:

a) The fixed end 351 is fixedly connected with the bottom frame 320, the operation end 352 bypasses the connection seat 340 and is located at the same side of the connection seat 340 as the fixed end 351 (for example, fig. 17), preferably, the operation end 352 bypasses one of the cross bars 341, and the outer contour of the contact part of the cross bar 341 and the flexible member 350 is circular, for example, a circular rod, so as to facilitate the movement of the flexible member 350;

b) The fixed end 351 is fixedly connected to the connection base 340 (e.g., fig. 18).

Wherein the locking means 360 allows movement of the flexible member 350 in a pulling direction (corresponding to movement of the connecting seat in a first direction) while preventing movement of the flexible member 350 in an opposite direction (i.e. a retraction direction described below) (corresponding to movement of the connecting seat in a second direction). The locking device 360 has:

a locked state allowing the flexible member 350 to move unidirectionally in the pulling direction, i.e., restricting the movement of the flexible member 350 in the retracting direction;

the unlocked state allows the flexure 350 to move bi-directionally.

As shown in fig. 19 to 22, the locking device 360 includes a locking base 361, a locking member 362, and an elastic member acting on the locking member 362, a channel 363 is formed between the locking member 362 and the locking base 361 for the flexible member 350 to pass through, and the locking device 360 is configured such that the locking member 362 and the locking base 361 clamp the flexible member 350 in a locked state, and the locking member 362 is only rotatable in one direction in this state. Specifically, the locking member 362 is rotatably mounted on the lock base 361 with an elastic member (e.g., a torsion spring) disposed therebetween, and the locking member 362 has locking teeth 364, the locking teeth 364 and the lock base 361 to provide a clamping force.

The locking member 362 rotates relative to the locking base 361 and has an unlocking direction (shown by an arrow in fig. 22) and a locking direction, as shown in fig. 22, when the operating end 352 of the flexible member 350 moves in the pulling direction, a force of the locking member 362 rotating in the unlocking direction is applied, so that a clamping force of the locking member 362 and the locking base 361 on the flexible member 350 is reduced or even eliminated, and as shown in fig. 21, when the operating end 352 of the flexible member 350 moves in the retracting direction, a force of the locking member rotating in the locking direction is applied, and a clamping force of the locking member 362 and the locking base 361 on the flexible member 350 is gradually increased, similar to self-locking. This structure realizes the aforementioned operation that the flexible member 350 can move unidirectionally, and can make the locking device 360 act on any position of the flexible member 350, ensuring that the supporting framework is in a unfolded state, thereby disregarding the influence of errors caused by processing and assembly. Before the carrying device is folded, after the lock member 362 is manually pressed to unlock the carrying device, the folding operation is performed by pressing the top frame 310.

Wherein the locking means 360 is provided at an edge of the bottom frame 320, for example, at one side in the X direction in the drawing. In an embodiment, the locking member 362 is limited to further rotate in the locking direction in the locked state, where the locking seat 361 is provided with a limiting portion, such as a boss on the locking seat 361, that abuts against the locking member 362. In an embodiment, a connection structure for fixing the flexible member 350 is provided between the flexible member 350 and the cloth bag 370, and the connection structure is, for example, a magic buckle provided between the flexible member 350 and the cloth bag 370, so as to prevent the part of the flexible member 350 exposed outside the cloth bag 370 from shaking randomly.

In connection with the placement of the adapter 400 on the bottom frame 320, the deployment process includes the side frame 100 being deployed while the carrying device 3000 is still in the stowed condition, then holding the side frame 100 or the bottom frame 320 and/or the foot-to-foot assembly 120 with one hand, and pulling the flexible member 350 to deploy the carrying device 3000 to switch to the in-use condition.
