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 first upper frame and a second upper frame that can be folded and retracted; The lower frame includes a first lower frame and a second lower frame that can be folded and retracted. The middle folding support rod includes a first support rod and a second support rod that are rotatably connected at the bottom and can be folded and retracted; the upper end of the first support rod is rotatably connected to the first upper frame, and the upper end of the second support rod is rotatably connected to the second upper frame. The first side connecting rod has its upper end rotatably connected to the first upper frame and its lower end rotatably connected to the first lower frame. The second side connecting rod has its upper end rotatably connected to the second upper frame and its lower end rotatably connected to the second lower frame.

[0005] As a preferred technical solution, a limiting component is provided between the upper frame or the middle folding support and the lower frame.

[0006] As a preferred technical solution, the limiting component is preferably a flexible limiting component; when the basket frame is in the unfolded state, the flexible limiting component is stretched and tightened, so that the lower frame is kept in the unfolded position.

[0007] As a preferred technical solution, the flexible limiting component is a cloth cover or part of a cloth cover fitted onto the outside of the basket frame.

[0008] As a preferred technical solution, at least one set of flexible limiting components is provided between the first upper frame or the first support rod and the first lower frame, and between the second upper frame or the second support rod and the second lower frame.

[0009] As a preferred technical solution, the flexible limiting component is a flexible pull strip.

[0010] As a preferred technical solution, the lower frame further includes a middle lower frame, wherein the first lower frame, the middle lower frame, and the second lower frame are rotatably connected in sequence.

[0011] As a preferred technical solution, the rotational connection axis between the first lower frame and the intermediate lower frame is parallel to the rotational connection axis between the second lower frame and the intermediate lower frame.

[0012] As a preferred technical solution, the rotatable connection between the first support rod and the second support rod corresponds to the intermediate lower frame.

[0013] As a preferred technical solution, the locking mechanism is disposed at the rotatable connection between the first upper frame and the second upper frame, or at the rotatable connection between the first support rod and the first upper frame, or at the rotatable connection between the second support rod and the second upper frame, or at the rotatable connection between the first support rod and the second support rod.

[0014] Compared with the prior art, this application has the following advantages: 1. In this application, both the upper and lower frames are foldable structures, and the linkage during the unfolding or folding process is achieved through the middle folding support rod, the first side connecting rod and the second side connecting rod. The overall structure is simple and novel, and it achieves bidirectional folding and folding, making the folded child basket smaller and easier to carry and store.

[0015] 2. The intermediate folding strut in this application has no rigid connection with the lower frame. The intermediate folding strut is only responsible for folding the upper frame and does not participate in folding the lower frame. It is no longer constrained by the lower frame. This design decomposes the complex folding action into two parallel and simpler folding paths (upper frame path and lower frame path), which facilitates ultra-thin folding and overall compactness.

[0016] 3. The lower frame in this application preferably adopts a three-section rotating connection structure (first lower frame, middle lower frame, and second lower frame), with its two ends folded and gathered together by the first side connecting rod and the second side connecting rod. The lower frame can be folded into a flatter "U" shape, so that the entire basket can be folded flatter, greatly reducing the thickness and space required for storage.

[0017] 4. This application incorporates a flexible limiting component. When the basket frame is unfolded and under load, the flexible limiting component is stretched, effectively providing an upward pulling force in the middle of the lower frame. This works in conjunction with the supports at both ends (the first and second side connecting rods) to significantly improve the stress distribution of the lower frame. This not only effectively prevents the lower frame from sagging and deforming in the middle, improving load-bearing capacity and structural stability, but also avoids the weight and cost associated with adding complex rigid connection mechanisms. Furthermore, this component does not require disassembly during folding, allowing it to relax naturally without affecting the original convenient storage, achieving a perfect balance between structural strength and ease of use.

[0028] Example 1: As Figure 1 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 foldable first upper frame 101 and a second upper frame 102; The lower frame 2 includes a first lower frame 201 and a second lower frame 203; The middle folding support rod 3 includes a first support rod 301 and a second support rod 302 that are rotatably connected at the bottom and can be folded and retracted; the upper end of the first support rod 301 is rotatably connected to the first upper frame 101, and the upper end of the second support rod 302 is rotatably connected to the second upper frame 102. The first side connecting rod 4 has its upper end rotatably connected to the first upper frame 101 and its lower end rotatably connected to the first lower frame 201. The second side connecting rod 5 is rotatably connected at its upper end to the second upper frame 102 and at its lower end to the second lower frame 203.

[0029] In this embodiment, the first upper frame 101 and the second upper frame 102 in the upper frame 1 can be directly rotatably connected (as shown in the figure of this embodiment), or they can be indirectly rotatably connected through an intermediate connector. That is, the upper frame 1 includes at least the first upper frame 101 and the second upper frame 102, but is not limited to only two segments. The first upper frame 101 and the second upper frame 102 form a U-shape with opposite openings to constitute a square-shaped upper frame 1. This is a conventional structure in this technical field, and therefore will not be described in detail here.

[0030] In this embodiment, the lower frame 2 is a two-section structure, and the first lower frame 201 and the second lower frame 203 are directly rotatably connected.

[0031] In this embodiment, there are two sets of the intermediate folding support rod 3, the first side connecting rod 4 and the second side connecting rod 5, which are arranged on the left and right sides of the child carrier respectively; wherein, the intermediate folding support rod 3 is located in the middle position in the front-back direction, while the first side connecting rod 4 and the second side connecting rod 5 are located on the front and rear sides of the intermediate folding support rod 3 respectively.

[0032] In this embodiment, the locking mechanism is located at the rotatable connection between the first upper frame and the second upper frame, or at the rotatable connection between the first support rod and the first upper frame, or at the rotatable connection between the second support rod and the second upper frame, or at the rotatable connection between the first support rod and the second support rod. Since the locking mechanism between the two rotating components is a conventional structure in this technical field and comes in various types, it will not be described in detail or limited here.

[0033] The working principle of this embodiment is as follows: When the child carrier is unfolded, the central folding support 3 opens, lifting the upper frame 1 to a flat position; the two sections of the lower frame 2 (first lower frame 201, second lower frame 203) unfold into a flat base, and the connecting rods on both sides (first side connecting rod 4, second side connecting rod 5) tighten the upper and lower frames, stabilizing the overall structure. At this time, the locking mechanism locks the carrier frame in place, thus keeping the entire child carrier in the unfolded state.

[0034] When the child carrier is folded, the locking mechanism is released, and the upper frame 1 is pressed down. The middle folding support 3 begins to retract, causing the first upper frame 101 and the second upper frame 102 to fold relative to each other around the rotation point. At the same time, during the folding process of the upper frame 1, the first lower frame 201 and the second lower frame 203 will rotate around their rotational connection axis through the pulling of the connecting rods on both sides (first side connecting rod 4 and second side connecting rod 5), thus folding and retracting.

[0035] Example 2: Figures 2 to 7As shown, the only difference between this embodiment and Embodiment 1 is that the lower frame 2 has a three-section structure. The lower frame 2 also includes a middle lower frame 202, and the first lower frame 201, the middle lower frame 202, and the second lower frame 203 are rotatably connected in sequence.

[0036] In this embodiment, the rotatable connection portions of the first support rod 301 and the second support rod 302 correspond to the intermediate lower frame 202. Preferably, the rotatable connection portions of the first support rod 301 and the second support rod 302 are concealed inside the left and right sides of the intermediate lower frame 202. In the figures of this embodiment, the first lower frame 201, the intermediate lower frame 202, and the second lower frame 203 all have a base plate, and the outer perimeter of the base plate corresponding to the lower frame forms an upwardly protruding side guard. The rotatable connection portions of the first support rod 301 and the second support rod 302 on both sides are located above the base plate of the intermediate lower frame 202 and inside its left and right side guards. This design, which conceals the rotatable connection portions within the base plate with side guards, greatly reduces the risk of injury from being pinched by moving parts. The side guards constitute a physical safety barrier, improving safety during use.

[0037] In this embodiment, the rotational connection axis A between the first lower frame 201 and the middle lower frame 202 is parallel to the rotational connection axis B between the second lower frame 203 and the middle lower frame 202. This design, which uses two parallel rotational axes to connect the three-section lower frame, not only ensures smooth folding but also provides extremely high structural stability, balancing the rigidity requirements of the product in use with the space requirements in storage. The folded size is compact, minimizing the space occupied and facilitating storage and transportation.

[0038] The working principle of this application is as follows: When the child carrier is unfolded, the central folding support 3 opens, lifting the upper frame 1 to a flat position; the three sections of the lower frame 2 (first lower frame 201, middle lower frame 202, and second lower frame 203) unfold into a flat base, and the connecting rods on both sides (first side connecting rod 4 and second side connecting rod 5) tighten the upper and lower frames, stabilizing the overall structure. At this time, the locking mechanism locks the carrier frame in place, thus keeping the entire child carrier in the unfolded state.

[0039] When the child carrier is folded, the locking mechanism is released, and the upper frame 1 is pressed down. The middle folding support 3 begins to retract, causing the first upper frame 101 and the second upper frame 102 to fold relative to each other around the rotation point. Simultaneously, during the folding process of the upper frame 1, through the pulling of the connecting rods on both sides (first side connecting rod 4 and second side connecting rod 5), the first lower frame 201 and the second lower frame 203 will rotate upwards around the rotational connecting shafts A and B between themselves and the middle lower frame 202, respectively, and retract towards the middle lower frame 202, completing a U-shaped fold. Finally, the entire carrier frame is compressed into a very flat shape.

[0040] Example 3: Figure 8 As shown, the only difference between this embodiment and Embodiment 2 is that a flexible limiting component 6 is provided between the upper frame 1 and the lower frame 2. Preferably, the flexible limiting component 6 is a cloth cover or a portion thereof (such as a crotch cover) fitted onto the outside of the basket frame, with its upper part connected to the upper frame 1 and its lower part connected to the lower frame 2.

[0041] Example 4: Figure 9 As shown, the difference between this embodiment and Embodiment 2 is only that: at least one set of flexible limiting components 6 are respectively provided between the first upper frame 101 and the first lower frame 201, and between the second upper frame 102 and the second lower frame 203. The flexible limiting component 6 is preferably a flexible pull strap, and the flexible pull strap is arranged to extend longitudinally.

[0042] Example 5: Figure 10 As shown, the difference between this embodiment and Embodiment 2 is only that at least one set of flexible limiting components 6 are provided between the first support rod 301 and the first lower frame 201, and between the second support rod 302 and the second lower frame 203. The flexible limiting component 6 is preferably a flexible pull strap, and the flexible pull strap extends forward and backward.

[0043] The main protection point of the above embodiments three, four, and five is that a flexible limiting component 6 is provided between the upper frame 1 or the middle folding support rod 3 and the lower frame 2; when the basket frame is in the unfolded state, the flexible limiting component 6 is stretched, so that the lower frame 2 is stably kept in the unfolded position. Given the variety of specific implementation methods, they will not be listed one by one in this article.

[0044] Its core advantage lies in the following: when the basket frame is unfolded and under load, the flexible limiting component 6 is stretched, which is equivalent to providing an upward pulling force in the middle of the lower frame 2. This effectively coordinates with the supports at both ends (the first side connecting rod 4 and the second side connecting rod 5), significantly improving the stress distribution of the lower frame 2. This not only effectively prevents the lower frame 2 from sagging and deforming in the middle, improving its load-bearing capacity and structural stability, but also avoids the weight and cost associated with adding complex rigid connection mechanisms. At the same time, this component does not need to be disassembled when folded, allowing it to relax naturally without affecting its original convenient storage, achieving a perfect balance between structural strength and ease of use.

[0045] In this application, both the upper frame 1 and the lower frame 2 are foldable structures, and the linkage during the unfolding or folding process is achieved through the middle folding support rod 3, the first side connecting rod 4 and the second side connecting rod 5. The overall structure is simple and novel, and it achieves bidirectional folding and folding, making the folded child basket smaller and easier to carry and store.

[0046] In this application, the intermediate folding strut 3 is not rigidly connected to the lower frame 2. The intermediate folding strut 3 is only responsible for folding the upper frame 1 and does not participate in the folding of the lower frame 2. It is no longer constrained by the lower frame 2. This design decomposes the complex folding action into two parallel and simpler folding paths (upper frame path and lower frame path), which facilitates ultra-thin folding and overall compactness.

This application is not limited to the above detailed solutions, that is, it does not mean that this application must rely on the above detailed solutions to be implemented.
