[0037] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0038] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments, and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0040] Unless otherwise stated, the "front" and "rear" in this application are relative concepts and do not limit their spatial positions in the movement direction of the child carrier. For example, "front top frame and rear top frame" should be understood as "first top frame and second top frame", and the same applies to "front bottom frame and rear bottom frame", "front side frame and rear side frame".

[0041] See attached Figure 1 to attached Figure 4 As shown, the present application discloses a child carrier having opposite unfolded states (see attached Figure 1 ) and folded states (see attached Figure 4 ), and the child carrier includes:

[0042] A front top frame 110 and a rear top frame 120, which are hinged through two first joints 130;

[0043] A front bottom frame 210 and a rear bottom frame 220, which are hinged through two second joints 230;

[0044] Two synchronization frameworks 300, each synchronization framework 300 is connected to one of the first joint 130 and the second joint 230 on the corresponding side, and is movably engaged with the other;

[0045] Two front side frames 410, the top of each front side frame 410 is hinged to the front top frame 110 on the corresponding side, the middle is hinged to the front bottom frame 210 on the corresponding side, and the bottom is used to connect the first roller 411;

[0046] Two rear side frames 420, the top of each rear side frame 420 is hinged to the rear top frame 120 on the corresponding side, the middle is hinged to the rear bottom frame 220 on the corresponding side, and the bottom is used to connect the second roller 421;

[0047] The front side frame 410, the front top frame 110, the front bottom frame 210 and the synchronization framework 300 on the corresponding side form a first deformation mechanism, and the rear side frame 420, the rear top frame 120, the rear bottom frame 220 and the synchronization framework 300 on the corresponding side form a second deformation mechanism.

[0048] See the appendix Figure 3 As shown, during the process of the children's vehicle entering the unfolded state, the front top frame 110 and the rear top frame 120 move away from each other, the front bottom frame 210 and the rear bottom frame 220 move away from each other, the first joint 130 and the second joint 230 on the corresponding side move away from each other along the synchronization framework 300 on the corresponding side, and the first deformation mechanism and the second deformation mechanism on the corresponding side deform synchronously; the front top frame 110, the rear top frame 120, the front bottom frame 210 and the rear bottom frame 220 enclose to form an accommodation space 900. In the appendix Figure 1 To the appendix Figure 4 As shown in, the first joint 130 provides a hinge point and realizes the coaxial hinge of the front top frame 110 and the rear top frame 120. The front top frame 110 and the rear top frame 120 swing with the first joint 130 as the rotation axis during the process of moving away from each other. In other embodiments, the first joint 130 can provide multiple hinge points and realize the non-coaxial hinge of the front top frame 110 and the rear top frame 120. The front top frame 110 and the rear top frame 120 swing with the corresponding hinge points as the rotation axes during the process of moving away from each other, and the multiple hinge points of the first joint 130 are rigidly connected. Similarly, the second joint 230 can also be provided with a single hinge point or multiple hinge points.

[0049] Through the cooperation relationship between components, a first deformation mechanism and a second deformation mechanism that are interconnected are formed by sharing the synchronization framework 300. During the state change of the child carrier, the components are interconnected to facilitate the deployment and folding operations; the accommodation space 900 formed by enclosing the front top frame 110, the rear top frame 120, the front bottom frame 210, and the rear bottom frame 220 can meet the comfortable sleeping or riding needs of children. In this embodiment, the maintenance of the deployed state and / or the folded state of the child carrier can be achieved through the mutual cooperation between components or through a separate locking mechanism. The locking mechanism can be arranged between components or within the first joint 130 or the second joint 230. The specific structure of the locking mechanism can be implemented in combination with the prior art.

[0050] The state change of the child carrier, especially the interconnection of the first deformation mechanism and the second deformation mechanism, depends on the setting of the synchronization framework 300. In one embodiment, each synchronization framework 300 defines a slideway; one end of each synchronization framework 300 is fixedly connected to the corresponding first joint 130, and the other end is movably fitted to the corresponding second joint 230 through the slideway. Further, each synchronization framework 300 provides a slideway through its outer peripheral surface, and a guiding hole adapted to the shape of the synchronization framework 300 is provided on the corresponding second joint 230, and the synchronization framework 300 is slidably fitted within the guiding hole. In different states, the cooperation relationship between the synchronization framework 300 and the first joint 130 and the second joint 230 changes. For example, when the child carrier is in the deployed state, the length of each synchronization framework 300 is adapted to the distance between the corresponding first joint 130 and the second joint 230; when the child carrier is in the folded state, the lower end of each synchronization framework 300 protrudes out of the corresponding second joint 230, and the corresponding front bottom frame 210 and rear bottom frame 220 are respectively located on both sides of the lower end of the synchronization framework 300. Further, the synchronization framework 300 is a rod extending linearly or curvilinearly.

[0051] From the perspective of the overall child carrier, see Figure 1In the illustrated embodiment, the child carrier is in the unfolded state, and the front side frame 410 and the rear side frame 420 on the corresponding sides gradually move away from each other from the top to the bottom, and the first roller 411 and the second roller 421 on the corresponding sides move away from each other to support the child carrier relative to the support surface. In the figure, the front side frame 410 and the rear side frame 420 form a herringbone structure to support the child carrier. Compared with the technical solution in the prior art that requires the seat or the sleeping basket to be installed on the walking frame, the child carrier in this embodiment directly sets the participating components of the deformation mechanism as support components for installing the rollers, which can simplify the number of components and improve the user experience. The first roller 411 and the second roller 421 can be set as needed. For example, the first roller 411 and / or the second roller 421 are a single roller or a wheel group with an axle. For another example, one of the first roller 411 and the second roller 421 is a front roller and the other is a rear roller. Similarly, see Figure 4 In the embodiment, when the child carrier is in the folded state, the front top frame 110 and the rear top frame 120 are close to the bottom of the first joint 130, and the front bottom frame 210 and the rear bottom frame 220 are close to the bottom of the second joint 230; the first joint 130 is located at the top of the child carrier, and the first roller 411 and the second roller 421 on the corresponding side are close to each other at the bottom of the child carrier. In this embodiment, a more compact folding performance can be provided. Furthermore, the front top frame 110 and the rear top frame 120 can change their own extension direction to improve the matching effect of the components. For example, the front top frame 110 and the rear top frame 120 are connected to the first joint 130 through the folding arm 140. In the unfolded state, the rotation axis of the first joint 130 is lower than the plane formed by the front top frame 110 and the rear top frame 120 because the folding arm 140 is set. In the folded state, the upper and lower spacings of the front top frame 110 and the rear top frame 120 are basically equal because of the setting of the folding arm 140.

[0052] In order to further optimize the user experience of the accommodating space 900, a flexible cloth cover (not shown) is provided on the front top frame 110, the rear top frame 120, the front bottom frame 210 and the rear bottom frame 220. When the child carrier is in the unfolded state, the cloth cover is stretched to surround the accommodating space 900; when the child carrier enters the folded state, the cloth cover is folded synchronously. In addition to defining the boundary of the accommodating space 900, the cloth cover can also be used to limit the positional relationship between the components to improve stability.

[0053] In terms of the specific structure of each component, the front top frame 110 and the rear top frame 120 are U-shaped structures with both ends of the openings used to connect the first joints 130, and the front bottom frame 210 and the rear bottom frame 220 are U-shaped structures with both ends of the openings used to connect the second joints 230. In the unfolded state, the front bottom frame 210 and the rear bottom frame 220 are located in the same plane to provide a supporting surface for the accommodating space 900, and the front top frame 110 and the rear top frame 120 are located in the same plane to form a ring structure away from the supporting surface.

[0054] To optimize the pushing experience of a child carrier, refer to the appendix Figure 1 In one embodiment, a push rod 500 is provided on the first joint 130. When the child carrier is in the deployed state, the push rod 500 is located at the deployed position and extends away from the front top frame 110 and the rear top frame 120 from the first joint 130. Refer to the appendix Figure 3 In the embodiment, during the process of the child carrier entering the folded state, the push rod 500 swings relative to the first joint 130, and moves towards the first roller 411 or the second roller 421 during the swinging process until it enters the folded position. The push rod 500 can be coaxially hinged to the front top frame 110 and / or the rear top frame 120, or can be independently hinged to the first joint 130, or can also be hinged through a rotating joint independent of the first joint 130. In one of the embodiments, the movement path of the push rod 500 between the deployed position and the folded position is located outside the accommodation space 900. In terms of implementation, the push rod 500 can be set as a U-shaped structure and the accommodation space 900 is avoided through the inner region of the U-shaped structure.

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as these combinations of technical features do not conflict, they should be considered as the scope described in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combination examples of the various embodiments involved at the same time.

[0056] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
