Referring to fig. 1-12, the present application provides a stroller 1000 having an unfolded state and a folded state, including two opposite side frames 100, and a seat 200 connected between the two side frames 100. The side stand 100 includes a front leg assembly 110, a rear leg assembly 120, a handle assembly 130, and a first link 140, and the side stand 100 is connected in a manner that:

The handle assembly 130 is in rotational engagement with the rear foot assembly 120, and the front foot assembly 110 and the rear foot assembly 120 are in rotational engagement. Specific connection means include, but are not limited to, the handlebar assembly 130 and the rear foot assembly 120 of the present application being hinged about a first axis 151, the front foot assembly 110 and the rear foot assembly 120 being hinged about a second axis 152, wherein the first axis 151 and the second axis 152 are not coaxial, and when folded, the handlebar assembly 130 is rotated closer to the rear foot assembly 120 and the front foot assembly 110 is driven closer to the rear foot assembly 120 by the first link 140.

The seat 200 comprises a seat 210 and a second connecting rod 220 for supporting the buttocks of the child, the seat 210 is in rotating fit with the rear foot assembly 120, two ends of the second connecting rod 220 are respectively hinged with the seat 210 and the front foot assembly 110, and when the seat is folded or unfolded, the front foot assembly 110 drives the seat 210 to rotate close to or far away from the rear foot assembly 120 through the second connecting rod 220.

Compared with the existing structure, the child stroller is simpler, and the seat can be folded and unfolded synchronously along with the side brackets, so that the child stroller is convenient to operate.

In one embodiment, the rear foot assembly 120, the handlebar assembly 130 and the front foot assembly 110 meet at a pivot joint 160, and the rear side of the seat 210 carries a connection seat 211 that is hinged to the pivot joint 160. The connection seat 211 is provided at the rear of the seat 210 such that the rear of the seat 210 does not protrude from the side bracket 100 in the folded state, i.e., the seat 210 does not protrude from the top of the side bracket after being folded, reducing the folded volume.

The rotary joint 160 includes a first joint element 161 fixedly connected to the rear foot assembly 120, and a second joint element 162 fixedly connected to the handle assembly 130, the first joint element 161 and the second joint element 162 are rotationally engaged about a first axis 151, wherein the connection base 211 is hinged to the rotary joint 160 about the first axis 151 and hidden by the rotary joint 160, i.e., the connection base 211 is hidden by the rotary joint 160 when viewed along the first axis 151.

As shown in fig. 6-9 or 10-12, the first joint element 161 and the second joint element 162 are formed of one or two iron sheets, the revolute joint 160 includes a hollow housing 165, the housing 165 and the hindfoot assembly 120 are fixedly connected, and the first joint element 161, the second joint element 162 and the first link 140 are located within the housing 165. Wherein the first joint element 161 comprises a disc-shaped body 163 and an extension 164 protruding radially (with respect to the first axis 151) with respect to the body 163, the forefoot component 110 is hinged to the extension 164, and the forefoot component 110 is more closed to the rearfoot component 120 when folded.

The seat 210 may be a plate-like or frame structure as shown in fig. 1, which extends along a first plane, and the connection seat 211 extends along a second plane, the first and second planes being perpendicular to each other. Wherein the seat 200 further comprises a cloth cover connected to the seat 210 and the handle assembly 130, and the cloth cover forms a backrest in an unfolded state of the stroller 1000, and is easy to fold and store when folded.

One end of the second link 220 is hinged to the connection seat 211, and in the unfolded state, the second link 220 is located below the seat 210, so that safety is higher. The first link 140 has one end hinged to the handle assembly 130 and a hinge point eccentrically disposed from the first axis 151 and the other end hinged to the forefoot assembly 110 and a hinge point eccentrically disposed from the second axis 152.

In one embodiment, the handle assembly 130 includes a lower handle 131 rotatably engaged with the rear foot assembly 120, and an upper handle 132, the upper handle 132 being foldable relative to the lower handle 131, and in the folded state, the handle assembly 130 has a length less than or equal to the rear foot assembly 120, resulting in a smaller folded volume. Wherein the stroller 1000 further comprises a locking mechanism with the side brackets 100 in an unfolded state, the upper handle 132 is folded relative to the lower handle 131 to unlock the locking mechanism.

Wherein, the front ends of the front foot assemblies 100 of the both side brackets 100 are connected, the upper ends of the handle assemblies 130 of the both side brackets 100 are connected, and wheels for movement are mounted at the bottoms of the front foot assemblies 110 and the rear foot assemblies 120.

Compared with the existing child cart, the child cart provided by the application has the advantages that the structure is simple, the seat can still be synchronously folded or unfolded along with the side support during folding and unfolding operations, and the operation is convenient.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description. When technical features of different embodiments are embodied in the same drawing, the drawing can be regarded as a combination of the embodiments concerned also being disclosed at the same time.

The foregoing examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application.
