Description

Technical Field

[0001] This application relates to the field of children's products technology, and in particular to a foldable children's basket. Background Technology

[0002] Traditional baby carriers typically include a foldable carrier frame and rotating components (such as handles or sunshade rods) located above the frame that can rotate relative to it. However, these rotating components usually require separate manual folding. Even after folding the carrier frame, users still need to perform additional steps to fully retract the device, making the process fragmented and cumbersome. Especially in emergency storage or one-handed operation scenarios, the multi-step folding mechanism can easily cause the rotating components to collide and deform due to failure to fold in time, or increase the user's workload. Summary of the Invention

[0003] The purpose of this application is to provide a child carrier that can be folded in conjunction with the frame, which can be folded or opened synchronously with the rotating parts, simplifying the operation steps, quickly completing the overall folding or unfolding, and improving the ease of use.

[0004] The technical solution of this application is: a foldable child carrier, including a carrier frame having an unfolded state and a folded state, a carrier frame locking mechanism that can lock the carrier frame in the unfolded state, and a rotating component that can rotate and fold relative to the carrier frame. The carrier frame is provided with a linkage seat that can rotate relative to it. The rotating component is rotatably connected to the linkage seat, and a rotating component locking mechanism is provided between the rotating component and the linkage seat. A linkage rod is rotatably connected between the linkage seat and the carrier frame, and the rotational connection point between the linkage rod and the carrier frame generates relative movement relative to the linkage seat when the carrier frame is folded.

[0005] When the basket rack is in the unfolded state, the basket rack locking mechanism is in the locked state, and the linkage seat remains in a non-rotatable state. At this time, the ability of the rotating component to rotate can be adjusted by unlocking or ununlocking the rotating component locking mechanism.

[0006] When the rotating component locking mechanism is in the unfolded and locked state and the basket frame locking mechanism is in the unlocked state, folding the basket frame can drive the rotating component to rotate and fold synchronously.

[0007] As a preferred technical solution, the basket frame includes an upper frame and a first support rod whose upper end is rotatably connected to the upper frame; the basket frame locking mechanism is disposed between the upper frame and the first support rod.

[0008] The upper frame can be a one-piece upper frame or a foldable upper frame that can be folded upwards.

[0009] One preferred technical solution is that the upper frame is a foldable upper frame that can be folded upwards, comprising a first upper frame and a second upper frame arranged rotatably on the left and right sides; the basket frame further comprises a second support rod, the lower part of the first support rod and the lower part of the second support rod are rotatably connected, 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 basket frame locking mechanism is disposed between the first support rod and the first upper frame, and the rotating component and the linkage seat are mounted on the first upper frame.

[0010] The linkage rod is rotatably connected between the linkage seat and the first support rod; the first support rod, the first upper frame, the linkage seat and the linkage rod together form a four-bar linkage mechanism.

[0011] The second preferred technical solution is that it differs from the first preferred technical solution only in the different positions of the linkage rod 12. In this technical solution, the linkage rod is rotatably connected between the linkage seat and the second upper frame; the first upper frame, the second upper frame, the linkage seat and the linkage rod together form a four-bar linkage mechanism.

[0012] In the above-mentioned preferred technical solutions two and three, the basket frame may further include a first lower frame whose inner end is rotatably connected to the lower part of the first support rod, and a second lower frame whose inner end is rotatably connected to the lower part of the second support rod; a first side frame is rotatably provided between the outer end of the first lower frame and the outer end of the first upper frame, and a second side frame is rotatably provided between the outer end of the second lower frame and the outer end of the second upper frame.

[0013] A third preferred technical solution is as follows: the upper frame is a foldable upper frame that can be folded upwards and retracted, which includes a first upper frame and a second upper frame arranged on the left and right sides and rotatably connected; the basket frame also includes a second support rod, the lower part of the first support rod and the lower part of the second support rod are rotatably connected, 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 basket frame locking mechanism is disposed between the first support rod and the first upper frame, and the rotating component and the linkage seat are installed on the first upper frame.

[0015] The linkage rod is rotatably connected between the linkage seat and the first lower frame.

[0016] As a preferred technical solution, the upper frame is an integral upper frame. The linkage rod is rotatably connected between the linkage seat and the first support rod; the first support rod, the upper frame, the linkage seat, and the linkage rod constitute a four-bar linkage mechanism.

[0017] As a preferred technical solution, the rotating component locking mechanism includes a first toothed groove formed on the linkage seat, a second toothed groove formed on the connecting end of the rotating component and corresponding to the first toothed groove, a gear disposed between the first toothed groove and the second toothed groove and capable of simultaneously locking the first toothed groove and the second toothed groove, a reset member disposed between the gear and the first toothed groove, and an unlocking member capable of pushing the gear to slide; when unlocking, the unlocking member pushes the gear out of the second toothed groove and fully retracts into the first toothed groove to achieve unlocking.

[0018] As a preferred technical solution, the rotating component is a handle or awning rod that is rotatably connected to both sides of the upper frame.

[0019] Compared with the prior art, this application has the following advantages:

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0040] In the description of this application and the claims, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates not less than two.

[0041] In the description of this application and the claims, the terms "connection," "installation," "fixation," and "reception," unless otherwise specified, should be interpreted broadly. For example, "connection" can mean a separate connection or an integral connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean a non-detachable connection or a detachable connection. As another example, "reception" does not necessarily mean complete containment; this concept also includes the containment of a portion that protrudes externally. Those skilled in the art can understand the specific meaning of the aforementioned terms in this application based on the specific circumstances.

[0042] In the description of this application and the claims, if terms such as "above," "below," or "horizontal" indicate orientation or positional relationships based on the orientation or positional relationships shown in the drawings, they are only for the purpose of clearly and simply describing this application, and do not indicate or imply that the elements referred to must have a specific orientation or be constructed and operated in a specific orientation. These directional terms are relative concepts used for relative description and clarification, and may change accordingly depending on the orientation of the components in the drawings. For example, if the device in the drawings is flipped, an element described as "below" other elements will be positioned "above" other elements.

[0043] In the description of this application specification and claims, the term "if" is generally interchangeable with "when," "at," "in response to determination," or "in response to detection," depending on the context.

[0044] In the description of this application and the claims, if there is a "direction" of motion, including motion with a directional component, the term "in direction" is not necessarily understood as motion only in that one direction. Those skilled in the art can understand the specific meaning of the aforementioned terms in this application according to the specific circumstances.

[0045] Example 1: As Figures 1 to 10 As shown, a child carrier that can be linked and folded includes a carrier frame having an unfolded state and a folded state, a carrier frame locking mechanism 5 that can lock the carrier frame in the unfolded state, and a rotating component 1 that can rotate and fold relative to the carrier frame.

[0046] In this embodiment, the basket rack includes:

[0047] The upper frame 2, which can be folded upward, includes a first upper frame 201 and a second upper frame 202 that are arranged on the left and right sides and rotatably connected.

[0048] The first support rod 3 is rotatably connected to the first upper frame 201 at its upper end;

[0049] The upper end of the second support rod 4 is rotatably connected to the second upper frame 202, and the lower part is rotatably connected to the lower part of the first support rod 3.

[0050] The inner end of the first lower frame 6 is rotatably connected to the lower part of the first support rod 3;

[0051] The inner end of the second lower frame 7 is rotatably connected to the lower part of the second support rod 4;

[0052] The upper end of the first side frame 8 is rotatably connected to the outer end of the first upper frame 201, and the lower end is rotatably connected to the outer end of the first lower frame 6.

[0053] The upper end of the second side frame 9 is rotatably connected to the outer end of the second upper frame 202, and the lower end is rotatably connected to the outer end of the second lower frame 7.

[0054] In this embodiment, the basket rack locking mechanism 5 is disposed between the first support rod 3 and the first upper frame 201. The basket rack locking mechanism 5 is a common locking mechanism in the prior art, and there are various types, so it will not be described in detail or limited here. Preferably, the unlocking component of the basket rack locking mechanism 5 is disposed on the outer end of the first upper frame 201 to facilitate folding operations.

[0055] In this embodiment, the first upper frame 201 is provided with a linkage seat 10 that can rotate relative to it, the rotating component 1 is rotatably connected to the linkage seat 10, and a rotating component locking mechanism 11 is provided between the rotating component 1 and the linkage seat 10.

[0056] The linkage seat 10 can be coaxially connected to the rotating component 1 and the first upper frame 201, or it can be coaxially connected to the rotating component 1 and the first upper frame 201 respectively.

[0057] In this embodiment, a linkage rod 12 is rotatably connected between the linkage seat 10 and the first support rod 3, and the first support rod 3, the first upper frame 201, the linkage seat 10, and the linkage rod 12 constitute a four-bar linkage mechanism. That is, the rotatable connection point between the linkage rod 12 and the basket frame moves relative to the linkage seat 10 when the basket frame is folded.

[0058] Example 2: Figure 11 As shown, the only difference between this embodiment and Embodiment 1 is the different position of the linkage rod 12. In this embodiment, the linkage rod 12 is rotatably connected between the linkage seat 10 and the second upper frame 201; the first upper frame 201, the second upper frame 202, the linkage seat 10 and the linkage rod 12 constitute a four-bar linkage mechanism.

[0059] Example 3: Figure 12 As shown, the only difference between this embodiment and the first embodiment is the different position of the linkage rod 12. In this embodiment, the linkage rod 12 is rotatably connected between the linkage seat 10 and the first lower frame 6.

[0060] Example 4: Figures 13 to 14 As shown, a foldable child carrier includes a carrier frame with an unfolded state and a folded state, a carrier frame locking mechanism 5 that locks the carrier frame in the unfolded state, and a rotating component 1 that can rotate and retract relative to the carrier frame. The carrier frame includes an integral upper frame 2 and a first support rod 3 whose upper end is rotatably connected to the upper frame 2 and can be rotatably retracted relative to the upper frame. The carrier frame locking mechanism 5 is disposed between the upper frame 2 and the first support rod 3. A linkage seat 10 that can rotate relative to the upper frame 2 is provided, and the rotating component 1 is rotatably connected to the linkage seat 10. A rotating component locking mechanism 11 is provided between the rotating component 1 and the linkage seat 10. A linkage rod 12 is rotatably connected between the linkage seat 10 and the first support rod 3. The first support rod 3, the upper frame 2, the linkage seat 10, and the linkage rod 12 constitute a four-bar linkage mechanism. That is, the rotatable connection point between the linkage rod 12 and the carrier frame (first support rod 3) moves relative to the linkage seat 10 when the carrier frame is folded.

[0061] The linkage seat 10 can be coaxially connected to the rotating component 1 and the upper frame 2, or it can be coaxially connected to the rotating component 1 and the upper frame 2 respectively.

[0062] Since there are various types of child carriers that can be folded up and down, this embodiment mainly protects the up-and-down folding child sleeping basket with an integrated upper frame and a first support rod that can be folded up and down relative to it. Therefore, no specific restrictions or descriptions are made on the number and specific structure of other parts of the sleeping basket.

[0063] In the above embodiments one, two, three, and four, the rotating component locking mechanism 11 preferably includes a first toothed groove 111 formed on the linkage seat 10, a second toothed groove 112 formed at the connecting end of the rotating component 1 and corresponding to the first toothed groove 111, a gear 113 disposed between the first toothed groove 111 and the second toothed groove 112 and capable of simultaneously locking the first toothed groove 111 and the second toothed groove 112, a reset member 114 disposed between the gear 113 and the first toothed groove 111, and an unlocking member 115 capable of pushing the gear 113 to slide; during unlocking, the unlocking member 115 pushes the gear 113 out of the second toothed groove 112 and fully retracts into the first toothed groove 111 to achieve unlocking. Since the locking structure and the press-to-unlock design of this rotating component locking mechanism 11 are common structures in the prior art, they will not be described in detail or limited here.

[0064] In this application, different types of rotating components 1 (such as handles, awning rods, etc.) can be adapted to enhance versatility. That is, the rotating component 1 can be a handle or awning rod rotatably connected to both sides of the upper frame.

[0065] The working principle of this application is as follows:

[0066] When the basket rack is in the unfolded state, the basket rack locking mechanism 5 is in the locked state, and the linkage seat 10 remains in the non-rotatable state. At this time, the rotating component 1 can be adjusted to rotate by unlocking or not unlocking the rotating component locking mechanism 11.

[0067] When the rotating component locking mechanism 11 is in the unfolded and locked state and the basket frame locking mechanism 5 is in the unlocked state, the rotating component 1 can be driven to rotate and fold synchronously by folding the basket frame, thereby completing the folding and folding of the entire child basket.

[0068] Conversely, when the child carrier is opened from the folded state, the carrier frame drives the rotating parts to open synchronously to the unfolded state through the linkage structure (linkage rod and linkage seat).

[0069] Another folding method of this application is as follows: First, release the locking mechanism 11 of the rotating component, so that the rotating component 1 is folded and retracted relative to the upper frame; then, while keeping the locking mechanism 11 of the rotating component in the unlocked state, release the locking mechanism 5 of the basket frame. At this time, folding the basket frame can drive the linkage seat 10 to rotate synchronously. When the basket frame is folded, release the unlocking piece 115, and the locking mechanism 11 of the rotating component will lock the linkage seat 10 and the rotating component 1 again. In this way, when the child basket is opened from the folded state, the basket frame can also drive the rotating component to open synchronously to the unfolded state through the linkage structure (linkage rod and linkage seat).

[0070] This application utilizes a linkage structure (linkage seat and linkage rod) to achieve synchronous folding or unfolding of the basket frame and rotating components, significantly simplifying the operation process. Users can complete the overall folding or unfolding with a single action, improving ease of use. Furthermore, the mechanical linkage avoids the risk of component misalignment associated with manual adjustments, enhancing structural stability and durability, making it particularly suitable for the needs of children's travel in fast-paced environments.

[0071] As a preferred embodiment of this application, in the description of this specification, the reference to terms such as "preferred," "optional," etc., means that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0072] The above embodiments are only used to illustrate the detailed solutions of this application. 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. Those skilled in the art should understand that any improvements to this application, equivalent substitutions of the raw materials of the product of this application, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of this application.
