Description

Technical Field

[0001] This application relates to the field of children's products, and more particularly to a foldable child carrier. Background Technology

[0002] Existing infant car seats are typically used as baby safety seats or independent bassinets and can be mounted on stroller frames. For ease of storage and transport, many car seats are designed to be foldable. However, traditional folding car seat structures are often quite complex, the folding operation is not smooth enough, or the folded size remains large. In some designs, interference between components can easily occur during folding, resulting in a poor folding experience and potentially damaging the product. Summary of the Invention

[0003] The purpose of this application is to provide a child carrier that has a simple structure, smooth folding operation, and small size after folding.

[0004] The technical solution of this application is: a child carrier, including a foldable carrier frame and a locking mechanism that can lock the carrier frame in an unfolded state, wherein the carrier frame includes: The upper frame includes a front upper frame and a rear upper frame that can be rotated and folded relative to each other; The basket base frame includes a front base frame and a rear base frame that can be rotated and folded relative to each other; The side hinge linkage mechanism is symmetrically arranged on the left and right sides of the upper frame and the basket base frame. Each side of the side hinge linkage mechanism includes an upper connector, an upper hinge, a lower hinge and a lower connector that are rotatably connected from top to bottom. The upper connector is rotatably connected to the front upper frame and the rear upper frame, and the lower connector is rotatably connected to the front base frame and the rear base frame. The front support rod has its upper end rotatably connected to the front upper frame and its lower end rotatably connected to the front base frame; The upper end of the rear support rod is rotatably connected to the rear upper frame, and the lower end is rotatably connected to the rear base frame; When the basket frame is folded, the upper and lower hinges on both sides fold inward and retract, causing the upper frame and the basket base to move closer together and retract.

[0005] As a preferred technical solution, in the side hinge linkage mechanism, the pivots between the upper hinge and the lower hinge, between the upper hinge and the upper connector, and between the lower hinge and the lower connector all extend in the front-to-back direction; while the pivots between the upper connector and the front upper frame and the rear upper frame, and between the lower connector and the front base frame and the rear base frame, all extend in the left-to-right direction.

[0006] One of the preferred technical solutions for the specific installation method of the front upper frame, the rear upper frame and the upper connecting piece is that the front upper frame and the rear upper frame are rotatably connected, and the upper connecting piece is coaxially rotatably connected to the front upper frame and the rear upper frame.

[0007] One of the preferred technical solutions for the specific installation method of the front upper frame, the rear upper frame and the upper connector is as follows: the upper connector is located between the front upper frame and the rear upper frame, and the front and rear ends of the upper connector are rotatably connected to the rear end of the front upper frame and the front end of the rear upper frame, respectively.

[0008] One of the preferred technical solutions for the specific installation method of the front base frame, the rear base frame and the lower connecting member is that the front base frame and the rear base frame are rotatably connected, and the lower connecting member is rotatably connected to the front base frame and the rear base frame on the same axis.

[0009] One of the preferred technical solutions for the specific installation method of the front base frame, the rear base frame and the lower connector is as follows: the lower connector is located between the front base frame and the rear base frame, and the front and rear ends of the lower connector are rotatably connected to the rear end of the front base frame and the front end of the rear base frame, respectively.

[0010] As a preferred technical solution, the upper end of the front support rod is rotatably connected to the front part of the front upper frame, and the lower end of the front support rod is rotatably connected to the front part of the front base frame; the upper end of the rear support rod is rotatably connected to the rear end of the rear upper frame, and the lower end of the rear support rod is rotatably connected to the rear end of the rear base frame.

[0011] As a preferred technical solution, the locking mechanism includes a first locking mechanism and a second locking mechanism; The first locking mechanism is disposed between the front upper frame and the rear upper frame, and is used to lock the two when they are deployed. The second locking mechanism is located at the rotatable connection between the upper hinge and the lower hinge, and is used to lock the two hinges when they are unfolded.

[0012] Compared with the prior art, this application has the following advantages: 1. This application achieves the coordinated folding of the upper frame and the basket base through an innovative "side hinge linkage mechanism" and a pivot design in a specific direction. During folding, the entire basket frame can be simultaneously retracted in multiple directions, with a smooth, one-step folding action. The final folded shape is very flat and compact, significantly reducing the space required for storage and transportation.

[0013] 2. In this application, the front and rear support rods and the side hinge linkage mechanism together constitute a spatial truss system. In the unfolded state, this structure effectively resists forces from all directions, ensuring the overall rigidity and stability of the basket and protecting the child's safety. The specific arrangement of the rotation axis makes the force flow transmission during folding more rational, avoiding motion interference.

[0014] 3. This application features a dual locking mechanism (the first locking mechanism locks the upper frame, and the second locking mechanism locks the side hinges). Folding can only begin when both locks are released simultaneously, effectively preventing accidental folding due to accidental contact during use and significantly improving safety performance.

[0025] Example: Figures 1 to 4 As shown, a child carrier includes a foldable carrier frame and a locking mechanism that locks the carrier frame in an unfolded state. The carrier frame includes: The upper frame 1 includes a front upper frame 101 and a rear upper frame 102 that can be rotated and folded relative to each other; The basket base frame 2 includes a front base frame 201 and a rear base frame 202 that can be rotated and folded relative to each other; The side hinge linkage mechanism 3 is symmetrically arranged on the left and right sides of the upper frame 1 and the basket base frame 2. Each side of the side hinge linkage mechanism 3 includes an upper connector 301, an upper hinge 302, a lower hinge 303 and a lower connector 304 that are rotatably connected from top to bottom. The upper connector 301 is rotatably connected to the front upper frame 101 and the rear upper frame 102, and the lower connector 304 is rotatably connected to the front base frame 201 and the rear base frame 202. The front support rod 4 has its upper end rotatably connected to the front upper frame 101 and its lower end rotatably connected to the front base frame 201; The upper end of the rear support rod 5 is rotatably connected to the rear upper frame 102, and the lower end is rotatably connected to the rear base frame 202; When the basket frame is folded, the upper hinges 302 and the lower hinges 303 on both sides fold inward and retract, causing the upper frame 1 and the basket base frame 2 to move closer to each other and retract.

[0026] In this embodiment, the front upper frame 101 is rotatably connected to the rear upper frame 102, and the upper connector 301 is coaxially rotatably connected to the front upper frame 101 and the rear upper frame 102.

[0027] In this embodiment, the lower connector 304 is located between the front base frame 201 and the rear base frame 202, and the front and rear ends of the lower connector 304 are rotatably connected to the rear end of the front base frame 201 and the front end of the rear base frame 202, respectively. There is no direct connection between the front base frame 201 and the rear base frame 202; their relative rotation and folding are achieved through the lower connector 304.

[0028] In this embodiment, in the side hinge linkage mechanism 3, the pivots between the upper hinge 302 and the lower hinge 303, between the upper hinge 302 and the upper connector 301, and between the lower hinge 303 and the lower connector 304 all extend in the front-to-back direction; while the pivots between the upper connector 301 and the front upper frame 101 and the rear upper frame 102, between the lower connector 304 and the front base frame 201, and between the lower connector 304 and the rear base frame 202 all extend in the left-to-right direction.

[0029] In this embodiment, the upper end of the front support rod 4 is rotatably connected to the front of the front upper frame 101, and the lower end of the front support rod 4 is rotatably connected to the front of the front base frame 201; the upper end of the rear support rod 5 is rotatably connected to the rear end of the rear upper frame 102, and the lower end of the rear support rod 5 is rotatably connected to the rear end of the rear base frame 202. All four connections are designed to rotate around an axis in the left-right direction.

[0030] In this embodiment, there are two front base frames 201 and two rear base frames 202, which are symmetrically arranged on the left and right sides of the basket frame; the front support rod 4 and the rear support rod 5 are preferably U-shaped with the opening facing downwards.

[0031] In this embodiment, the locking mechanism includes a first locking mechanism and a second locking mechanism. The first locking mechanism is disposed between the front upper frame 101 and the rear upper frame 102, and is used to lock both when unfolded. The second locking mechanism is disposed at the rotatable connection between the upper hinge 302 and the lower hinge 303, and is used to lock both when unfolded. Since locking mechanisms are conventional structures in this technical field and come in various types, they will not be specifically described or limited here. This application uses a dual locking mechanism (the first locking mechanism locks the upper frame 1, and the second locking mechanism locks the side hinges). Folding can only begin when both locks are released simultaneously, effectively preventing accidental folding due to accidental contact during use, and significantly improving safety performance.

[0032] The folding mechanism of this child carrier works as follows: When the basket needs to be folded, the locking mechanisms on the basket frame must first be released. This involves unlocking the first locking mechanism used to lock the front upper frame 101 and the rear upper frame 102, and the second locking mechanism used to lock the rotatable connection between the upper hinge 302 and the lower hinge 303. After unlocking, the operator can apply pressure inward from both sides of the basket. At this time, the side hinge linkage mechanism 3 on both sides begins to operate, and the upper hinge 302 and the lower hinge 303 fold inward.

[0033] This folding action causes the upper frame 1 and the basket base 2 to move closer together vertically. Simultaneously, guided and constrained by the front and rear support rods 4 and 5, and through the rotation of the segmented frames (such as between the front and rear upper frames 101 and 102, and between the front and rear base frames 201 and 202), the entire structure is simultaneously folded and retracted in the front-to-back direction. Ultimately, the basket frame, through this composite folding, smoothly folds into a compact whole, significantly reducing its storage volume.

[0034] When unfolded, simply open each component to its designated position and lock it to restore its usability.

[0035] This application achieves the coordinated folding of the upper frame 1 and the basket base 2 through an innovative "side hinge linkage mechanism 3" and a pivot design in a specific direction. During folding, the entire basket frame can be simultaneously retracted in multiple directions, with a smooth and one-step folding action. The final folded shape is very flat and compact, significantly reducing the space required for storage and transportation.

[0036] In this application, the front support rod 4, the rear support rod 5, and the side hinge linkage mechanism 3 together form a spatial truss system. In the unfolded state, this structure effectively resists forces from all directions, ensuring the overall rigidity and stability of the basket and protecting the child's safety. The specific arrangement of the rotation axis makes the force flow during folding more rational, avoiding motion interference.
