The lower end surface of the assembly 81 is flush with the lower end surface of the bottom support 22 when the basket 10 is in the unfolded state, so that the assembly 81 can support the basket 10 on the ground together with the bottom support 22, thereby supporting more stably. In this embodiment, the assembly seat 8 may further include a contact member 82 having two ends connected to the lower sides of the two assemblies 81, respectively, and the contact member 82 is located below the lower frame 2. Thus, when the basket 10 of the present invention is supported on the ground, the connecting members 82 are equivalent to connecting the two sides of the basket, and similarly, the connecting members 32 connect the two sides of the basket, thus further making the basket 10 more stable and safer in the unfolded state.

As shown in fig. 16 to 21, the present invention discloses a stroller comprising a frame convertible between an unfolded state and a folded state and a basket connected to the frame, wherein the basket is configured as the infant basket 10.

The frame 20 is provided with a matching seat, and the assembling seat 8 of the lifting basket 10 is connected with the matching seat, so that the lifting basket 10 and the frame 20 are assembled. The assembling seat 8 and the mating seat may be detachably connected, or may be any other known and feasible connection manner, and are not described herein.

Because the basket 10 is assembled on the frame through the assembling seat 8, the folding of the basket 10 is not limited by the frame, so that the basket 10 loaded on the frame can be independently and completely folded in the unfolded state of the frame; the lifting basket is pivoted with the assembling seat, so that the lifting basket can rotate relative to the frame, the lifting basket does not need to be detached from the frame when the infant handcart is folded, and the folded lifting basket can rotate relative to the frame after being folded, so that the operation of detaching the lifting basket is avoided, the integral folding operation of the infant handcart is simpler and more convenient, and after the frame is folded, the folded lifting basket can be relatively close to each component of the folded frame, and the integral folded volume of the whole infant handcart is relatively smaller, so that the infant handcart is convenient to carry and store; the volume of the folded basket is small, so that the whole volume of the infant handcart after being folded can be further reduced. Moreover, because the unlocking of the second locking mechanism is achieved through linkage unlocking when the lifting basket is folded, under the condition that the lifting basket folding operation is not carried out, the lifting basket cannot be independently rotated relative to the assembly seat, namely, the lifting basket cannot be independently rotated relative to the frame, so that the lifting basket can be prevented from rotating due to misoperation, and damage to children in the lifting basket caused by the misoperation is avoided.

The matching seat comprises two matching pieces 201 which are arranged on the frame at intervals, and the two matching pieces 201 are respectively connected with the two assembling pieces 81.

In this embodiment, the frame 20 includes left and right side brackets 201, and each of the side brackets 201 is provided with one of the engaging members 201. So that the basket, after being assembled to the frame, can be positioned between the brackets on both sides.

Each side bracket 201 comprises a front foot 202, a sliding piece 203 which is connected to the front foot 202 in a relatively up-down movable way, a rider 204 which is connected to the sliding piece 203 at the lower side, a rear foot 205 which is pivoted to the sliding piece 203 at the front side, and a connecting rod 206, wherein the upper side of the connecting rod 206 is pivoted to the upper side of the front foot 202, and the lower side is pivoted to the rear foot 205; the upper side of the front leg 202 of each side bracket is provided with the matching piece 201; the engaging member 201 is located at the upper side of the slider 203, so that the engaging member 201 can be prevented from interfering with the sliding of the slider 203.

When the frame 20 is folded, the rider 204 can be pushed downwards, so that the rider 204 and the sliding piece 203 move downwards relative to the front leg 202, the front end of the rear leg 205 is driven to move together with the sliding piece 203 and rotate relative to the sliding piece 203, meanwhile, as the rear leg 205 rotates and moves in a rotating way, the lower end of the connecting rod 206 is driven to move downwards forwards, and as the upper end of the connecting rod 206 is pivoted on the upper side of the front leg 202, the rear side of the rear leg 205 is driven to rotate towards the direction of the front leg 202 at the same time under the action of the connecting rod 206 until the rider 204 and the sliding piece 203 can not move downwards any more; at this time, the front leg 202, the rear leg 205, the rider 204, and the link 206 are close to each other, and the frame 20 is in a folded state. Before folding the infant stroller of the present invention, the basket 10 may be folded, and when the basket 10 is folded, the slide 4 also unlocks the second locking mechanism, and then the folded basket 10 is rotated forward and downward to be relatively close to the front legs 202, and then the frame 20 is folded, thereby completing the overall folding of the infant stroller. That is, because the basket 10 is pivoted with the assembling seat 8, the basket 10 connected to the frame 20 through the assembling seat 8 can rotate relative to the frame 20, and further the folded basket 10 can be relatively close to each component of the folded frame 20, so that the folded volume of the whole baby stroller can be reduced, and the baby stroller is convenient to carry and store; the folded basket has small volume, and the whole volume of the folded baby stroller can be further reduced

The frame 20 further includes left and right push handles 209, and the lower sides of the push handles 209 are respectively pivoted to the upper sides of the handles 204 of the two side brackets, or the lower sides of the push handles are respectively connected to the upper sides of the handles 204 of the two side brackets in a relatively up-and-down movable manner. When the frame 20 is folded, the push handle can be rotated downwards or moved downwards, so that the push handle is folded, the overall height of the frame 20 is reduced, and the overall size of the infant stroller is reduced.

The frame 20 further includes a front wheel 207 coupled to a front lower portion of the front foot 202, and a rear wheel 208 coupled to a rear lower portion of the rear foot 205.

In other embodiments, the specific structure of the frame may be any other known feasible structure, as long as the matching seat can be matched with the basket without affecting the folding of the basket.

In the above description of the relative orientations, the directions in which the two support pipes 11 are located are the front and rear, the directions in which the support pipes 11 are located are the upward, the directions in which the bottom plate 21 is located are the downward, and the directions in which the two side pipes 111 of the support pipes 11 are located are the left and right. It will be appreciated by those skilled in the art that the foregoing description of the orientation is merely for convenience of description of the invention and is not intended to specifically address the particular orientation of the components involved and thus should not be construed as limiting the invention; it will also be appreciated that as the viewing vision changes, the orientation changes correspondingly uniformly.
