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 achieves a high degree of balance between stability and portability through a clever combination of a few rods and rotating connection points.

[0004] The technical solution of this application is: a child carrier, including a foldable carrier frame and a carrier frame 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; A 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 collapsed; the upper end of the first support rod is rotatably connected to a first upper frame, the upper end of the second support rod is rotatably connected to a second upper frame, and the lower part of the first support rod is rotatably connected to a first lower frame. The first connecting rod has its upper end rotatably connected to the first upper frame and its lower end rotatably connected to the lower frame. The second connecting rod is rotatably connected at its upper end to the second upper frame and at its lower end to the second lower frame.

[0005] As a preferred technical solution, the lower end of the first connecting rod can be assembled with the lower frame in several ways: The first configuration involves the lower end of the first connecting rod being rotatably connected to both the first lower frame and the second lower frame. There is no other direct connection between the first lower frame and the second lower frame.

[0006] The second type is: the first lower frame and the second lower frame are rotatably connected, and the lower end of the first connecting rod is rotatably connected to the first lower frame or the second lower frame.

[0007] The third type is: the lower end of the first connecting rod is coaxially connected to the first lower frame and the second lower frame.

[0008] As a preferred technical solution, the first upper frame and the second upper frame can be directly rotatably connected, or they can be indirectly rotatably connected through an intermediate connector. If an intermediate connector is provided between the first upper frame and the second upper frame, preferably, the first upper frame is rotatably connected to one end of the intermediate connector, and the second upper frame is rotatably connected to the other end of the intermediate connector.

[0009] As a preferred technical solution, the upper part of the basket frame is provided with a rotating component that can rotate relative to it, and a locking mechanism for the rotating component is provided between the rotating component and the basket frame.

[0010] As a preferred technical solution, the rotating component locking mechanism can lock or unlock the rotating component independently of the basket frame locking mechanism; when the basket frame locking mechanism is unlocked, it can trigger the rotating component locking mechanism to unlock in conjunction.

[0011] As a preferred technical solution, the basket frame locking mechanism is disposed at the rotatable connection between the first support rod and the first upper frame; the rotating component is rotatably mounted on the first upper frame, and the rotating component locking mechanism is disposed between the rotating component and the first upper frame.

[0012] As a preferred technical solution, the basket rack locking mechanism includes a first locking component and a first unlocking component. The first locking component is used to lock the first support rod to the first upper frame; the first unlocking component is used to release the lock of the first locking component. The rotating component locking mechanism includes a second locking component and a second unlocking component. The second locking component is used to lock the rotating component to the first upper frame; the second unlocking component is used to release the lock of the second locking component. The first unlocking component is connected to a sliding component; the sliding component is slidably disposed on the first upper frame and a third reset component is disposed between the two; the sliding component contacts the second unlocking component through a driving part.

[0013] As a preferred technical solution, the first locking component can be installed in one of the following two ways: The first method is as follows: the sliding component and the first locking component are respectively connected to the first unlocking component; when the first unlocking component is operated to unlock, the first unlocking component directly drives the first locking component to release the lock on the basket frame; at the same time, it drives the sliding component to slide along a path, and the sliding component acts on the second unlocking component, causing it to drive the second locking component to release the lock on the rotating component.

[0014] The second method is as follows: the sliding component is disposed between the first unlocking component and the first locking component; when the first unlocking component is operated to unlock, the sliding component is driven to slide along a path. The sliding component simultaneously acts on the first locking component and the second unlocking component, causing the first locking component to release the lock on the basket frame, and in conjunction with it, causing the second unlocking component to drive the second locking component to release the lock on the rotating component.

[0015] As a preferred technical solution, the rotating component has a first mounting seat at the connecting end, and the first upper frame has a second mounting seat corresponding to the first mounting seat; The second locking component includes a locking member movably mounted on the first mounting base, a first reset member disposed between the locking member and the first mounting base, and a first locking groove formed on the second mounting base corresponding to a first protrusion at the movable end of the locking member; The second unlocking component includes a button that is slidably disposed on the first upper frame and can drive the locking component to perform an unlocking movement, and a second reset component disposed between the button and the first upper frame; When the rotating component rotates relative to the first upper frame to the working position, the first protrusion of the locking member is engaged in the corresponding first locking groove under the action of the first reset member, thereby locking the rotating component and the first upper frame. When it is necessary to rotate the rotating component, press the button, the button slides and drives the locking component to unlock, so that the first protrusion exits the corresponding first locking groove, thereby unlocking the rotating component from the first upper frame.

[0016] As a preferred technical solution, the locking element is rotatably mounted on the first mounting base.

[0017] As a preferred technical solution, the rotating component can have one or more working positions relative to the first upper frame; the number of the first locking grooves is consistent with the number of the aforementioned working positions.

[0018] As a preferred technical solution, the first upper frame has a third mounting seat, and the upper end of the first support rod has a fourth mounting seat corresponding to the third mounting seat; The first locking component includes a first toothed groove formed in the third mounting base, a second toothed groove formed in the fourth mounting base and corresponding to the first toothed groove, a gear disposed between the third mounting base and the fourth mounting base and capable of simultaneously locking the first toothed groove and the second toothed groove, a linkage disposed between the gear and the first toothed groove and capable of rotation and axial displacement, and a fourth reset component disposed between the gear and the second toothed groove; wherein, the first toothed groove has a protruding guide wedge, and the linkage has a guide groove that engages with the inclined surface of the guide wedge; The first unlocking component is mounted on the first upper frame and connected to the sliding component via a first traction cable; the linkage component is connected to the sliding component or the first unlocking component via a second traction cable. The button has a second protrusion, and the sliding component has an unlocking groove that engages with the inclined surface of the second protrusion; the unlocking groove constitutes the driving part of the sliding component.

[0019] As a preferred technical solution, the lower part of the first support rod and / or the second support rod is equipped with a basket mounting seat that can be detachably assembled with the stroller.

[0020] As a preferred technical solution, the first upper frame and the second upper frame are U-shaped with their openings facing each other.

[0021] Compared with the prior art, this application has the following advantages: 1. This application achieves a highly efficient balance between stability and portability through a clever combination of a small number of rods and rotating connection points. When unfolded, it forms a stable frame composed of multiple triangles and quadrilaterals, with reasonable stress distribution and strong load-bearing capacity; when folded, it quickly folds into a compact whole through the coordinated movement of each component around the rotating point, greatly saving storage space and achieving smooth "one-click" folding and unfolding.

[0022] 2. The design essence of the basket rack in this application lies in its unique "first link," which connects to the first upper frame and rotates to the first and / or second lower frame, forming a crucial linkage hub. This design not only significantly enhances the overall rigidity and load-bearing capacity of the bottom in the unfolded state but also ensures synchronized and smooth movements during folding. Simultaneously, placing the "second link" on the outer side optimizes the lever arm, making the unfolding and folding on the other side more effortless and stable. This asymmetrical linkage mechanism allows the upper frame and folding support to work together, ultimately efficiently folding the entire basket rack into a compact package, greatly saving storage and transportation space.

[0023] 3. This application achieves a "one-click folding" function by setting up a linkage between the basket frame locking mechanism and the rotating component locking mechanism. When the user needs to fully fold the basket frame, they only need to operate the basket frame locking mechanism to unlock both the basket frame and the rotating component simultaneously, avoiding the cumbersome two-step operation and greatly improving the efficiency and convenience of the folding operation.

[0024] 4. This application introduces a sliding component as the core transmission element to simultaneously and precisely distribute the single action of the first unlocking component to two different locking mechanisms (the first locking component of the basket rack locking mechanism and the rotating component locking mechanism). This "one-to-two" linkage design is ingenious, ensuring the synchronization of the two unlocking actions and avoiding the asynchronous or jamming problems that may occur due to step-by-step operation, resulting in high reliability of the action.

[0025] 5. This application ingeniously achieves "one-way linkage." That is, operating the first unlocking component (overall folding) will necessarily activate the locking mechanism of the rotating component; however, operating the second unlocking component (folding the rotating component separately) will not affect the locking mechanism of the basket frame at all. This logic is rigidly implemented through the mechanical structure, making the operation intuitive and less prone to errors, while ensuring that the stability of the basket frame itself is not affected when folding the rotating component separately.

Detailed Implementation

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] like Figures 1 to 14 As shown, a child carrier includes a foldable carrier frame 100 and a carrier frame locking mechanism 200 that locks the carrier frame 100 in an unfolded state. The carrier frame 100 includes: The upper frame 110 includes a foldable first upper frame 111 and a second upper frame 112; The lower frame 120 includes a first lower frame 121 and a second lower frame 122; The folding support rod 130 includes a first support rod 131 and a second support rod 132 that are rotatably connected at the bottom and can be folded and retracted; the upper end of the first support rod 131 is rotatably connected to the first upper frame 111, the upper end of the second support rod 132 is rotatably connected to the second upper frame 112; and the lower part of the first support rod 131 is rotatably connected to the first lower frame. The first connecting rod 140 has its upper end rotatably connected to the first upper frame 111 and its lower end rotatably connected to the lower frame 120. The second connecting rod 150 is rotatably connected at its upper end to the second upper frame 112 and at its lower end to the second lower frame 122.

[0037] In this embodiment, the lower end of the first connecting rod 140 can be assembled with the lower frame 120 in several ways: The first configuration involves the lower end of the first connecting rod 140 being rotatably connected to both the first lower frame 121 and the second lower frame 122. There is no other direct connection between the first lower frame 121 and the second lower frame 122.

[0038] The second type is: the first lower frame 121 and the second lower frame 122 are rotatably connected, and the lower end of the first connecting rod 140 is rotatably connected to the first lower frame 121 or the second lower frame 122.

[0039] The third type is: the lower end of the first connecting rod 140 is coaxially connected to the first lower frame 121 and the second lower frame 122.

[0040] In this embodiment, the first assembly method described above is preferred. More preferably, the first connecting rod 140 is located between the first support rod 131 and the second support rod 132, and the rotation point of its upper end with the first upper frame 111 is located between the rotation point of the first support rod 131 and the first upper frame 111 and the rotation point of the second support rod 132 and the second upper frame 112; the second connecting rod 150 is rotatably disposed between the outer end of the second upper frame 112 and the outer end of the second lower frame 122.

[0041] In this embodiment, the lower part of the first support rod 131 and / or the second support rod 132 is equipped with a basket mounting base 160 that can be detachably assembled with the stroller.

[0042] In this embodiment, the first upper frame 111 and the second upper frame 112 in the upper frame 1 can be directly rotatably connected (as in this embodiment). Figures 1 to 8 As shown in the figure, the two can also be indirectly rotated together via an intermediate connector 113 (as in this embodiment). Figure 13 and Figure 14 (As shown in the diagram). If an intermediate connecting member is provided between the first upper frame 111 and the second upper frame 112, preferably, the first upper frame 111 is rotatably connected to one end of the intermediate connecting member 113, and the second upper frame 112 is rotatably connected to the other end of the intermediate connecting member 113. That is, the upper frame 1 includes at least the first upper frame 111 and the second upper frame 112, 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.

[0043] The essence of the basket rack 1 design in this application lies in its unique "first link 140," which connects to the first upper frame 111 at the top and simultaneously rotatably connects to the first and second lower frames 121 and 122 at the bottom, forming a crucial linkage hub. This design not only significantly enhances the overall rigidity and load-bearing capacity of the bottom in the unfolded state but also ensures the synchronization and smoothness of the movement during folding. Meanwhile, the "second link 150" is positioned on the outer side, optimizing the lever arm and making the unfolding and folding of the other side more effortless and stable. This asymmetrical linkage mechanism allows the upper frame 100 and the folding support rod 130 to work together, ultimately efficiently folding the entire basket rack 1 into a compact package, greatly saving storage and transportation space.

[0044] In this embodiment, the upper part of the basket frame 100 is provided with a rotating component 300 that can rotate relative to it, and a rotating component locking mechanism 400 is provided between the rotating component 300 and the basket frame 100. The rotating component locking mechanism 400 can lock or unlock the rotating component 300 independently of the basket frame locking mechanism 200; when the basket frame locking mechanism 200 is unlocked, it can trigger the rotating component locking mechanism 400 to unlock. The rotating component 300 can be a handle or a canopy rod. Since this is a conventional structure in the prior art, it will not be described in detail or limited here.

[0045] Preferably, the basket frame locking mechanism 200 is disposed at the rotatable connection between the first support rod 131 and the first upper frame 111; the rotating component 300 is rotatably mounted on the first upper frame 111, and the rotating component locking mechanism 400 is disposed between the rotating component 300 and the first upper frame 111.

[0046] The basket rack locking mechanism 200 includes a first locking component 210 and a first unlocking component 220. The first locking component 210 is used to lock the first support rod 131 to the first upper frame 111; the first unlocking component 220 is used to release the lock of the first locking component 210. The rotating component locking mechanism 400 includes a second locking component 410 and a second unlocking component 420. The second locking component 410 is used to lock the rotating component 300 to the first upper frame 111; the second unlocking component 420 is used to release the lock of the second locking component 410. The first unlocking member 220 is connected to a sliding member 230; the sliding member 230 is slidably disposed on the first upper frame 111 and a third reset member 240 is disposed between the two; the sliding member 230 contacts the second unlocking member 420 through a driving part.

[0047] The first locking component 210 can be installed in one of the following two ways: The first method is as follows: the sliding component 230 and the first locking component 210 are respectively connected to the first unlocking component 220; when the first unlocking component 220 is operated to unlock, the first unlocking component 220 directly drives the first locking component 210 to release the lock on the basket frame 100; at the same time, it drives the sliding component 230 to slide along a path, and the sliding component 230 acts on the second unlocking component 420, causing it to drive the second locking component 410 to release the lock on the rotating component 300.

[0048] The second method is as follows: the sliding component 230 is disposed between the first unlocking component 220 and the first locking component 210; when the first unlocking component 220 is operated to unlock, the sliding component 230 is driven to slide along a path. The sliding component 230 simultaneously acts on the first locking component 210 and the second unlocking component 420, causing the first locking component 210 to release the lock on the basket rack 100, and in conjunction with it, driving the second unlocking component 420 to drive the second locking component 410 to release the lock on the rotating component 300.

[0049] In this embodiment, the second method described above is preferred, and the sliding component 230 is disposed between the first unlocking component 220 and the first locking component 210.

[0050] The preferred installation structure and working principle of the rotating component locking mechanism 400 in this embodiment are as follows: The rotating component 300 has a first mounting base 310 at its connecting end, and the first upper frame 111 has a second mounting base 1111 corresponding to the first mounting base 310. The second locking assembly 410 includes a locking member 411 movably mounted on the first mounting base 310, a first reset member 412 disposed between the locking member 411 and the first mounting base 310, and a first locking groove 413 formed on the second mounting base 1111 corresponding to a first protrusion 4111 at the movable end of the locking member 411. The second unlocking member 420 includes a button 421 that is slidably disposed on the first upper frame 111 and can drive the locking member 411 to perform an unlocking movement, and a second reset member 422 disposed between the button 421 and the first upper frame 111; When the rotating component 300 rotates to the working position relative to the first upper frame 111, the first protrusion 4111 of the locking component 411 is engaged in the corresponding first locking groove 413 under the action of the first reset component 412, thereby locking the rotating component 300 and the first upper frame 111. When it is necessary to rotate the rotating component 300, press the button 421. The button 421 slides and drives the locking component 411 to perform an unlocking movement, so that the first protrusion 4111 exits the corresponding first locking groove 413, thereby unlocking the rotating component 300 from the first upper frame 111.

[0051] The locking member 411 is preferably rotatably mounted on the first mounting base 310.

[0052] The rotating component 300 can have one or more working positions relative to the first upper frame 111; the number of sets of the first locking grooves 413 is consistent with the number of the aforementioned working positions. That is, the rotating component 300 can be a single-position lock or a multi-position lock.

[0053] The preferred installation structure and working principle of the basket rack locking mechanism 200 in this embodiment are as follows: The first upper frame 111 has a third mounting seat 1112, and the upper end of the first support rod 131 has a fourth mounting seat 1311 corresponding to the third mounting seat 1112; The first locking component 210 includes a first toothed groove 211 formed in the third mounting base 1112, a second toothed groove 212 formed in the fourth mounting base 3011 and corresponding to the first toothed groove 211, a gear 213 disposed between the third mounting base 112 and the fourth mounting base 3011 and capable of simultaneously locking the first toothed groove 211 and the second toothed groove 212, a linkage member 214 disposed between the gear 231 and the first toothed groove 211 and capable of rotation and axial displacement, and a fourth reset member 215 disposed between the gear 213 and the second toothed groove 212; wherein, the first toothed groove 211 has a protruding guide wedge 2111, and the linkage member 214 has a guide wedge 2141 that engages with the inclined surface of the guide wedge 2111; The first unlocking component 220 is mounted on the first upper frame 111 and connected to the sliding component 230 via a first traction cable 250. The linkage component 214 is connected to the first unlocking component 220 via a second traction cable 260. The first traction cable 250 and the second traction cable 260 can be two independent cables or a Y-shaped single cable structure. When a Y-shaped structure is used, its main end is connected to the first unlocking component 220, and the two branch ends are respectively connected to the sliding component 230 and the linkage component 214. The button 421 has a second protrusion 4211, and the sliding member 230 has an unlocking groove 231 that engages with the inclined surface of the second protrusion 4211; the unlocking groove 230 constitutes the driving part of the sliding member 230.

[0054] During unlocking, the first unlocking member 220 drives the linkage member 214 to rotate via the second traction cable 260. The linkage member 214's guide groove 2141 engages with the inclined surface of the guide block 2111, causing the linkage member 214 to move axially. This pushes the gear 213 out of the first tooth groove 211 and fully retracts into the second tooth groove 212, thus unlocking the basket rack 100. Simultaneously, the first unlocking member 220 drives the sliding member 230 to slide via the first traction cable 250. The sliding member 230 engages with the inclined surface of the second protrusion 4211 via the unlocking groove 231, causing the button 421 to move in the unlocking direction. This, in turn, causes the locking member 411 to move in the unlocking direction, causing the first protrusion 4111 to exit the corresponding first locking groove 413, thus unlocking the rotating member 300.

[0055] The first unlocking component 220 can be a rotary unlocking structure, a sliding unlocking structure, or a press-type unlocking structure. Since the first unlocking component 220 is a conventional structure in the prior art, it will not be described in detail or limited here.

[0056] This application achieves a "one-click folding" function by setting a linkage between the basket rack locking mechanism 200 and the rotating component locking mechanism 400. When the user needs to fully fold the basket rack, they only need to operate the basket rack locking mechanism 200 to unlock both the basket rack 100 and the rotating component 300 simultaneously, avoiding the cumbersome two-step operation and greatly improving the efficiency and convenience of the folding operation.

[0057] This application introduces a sliding component 230 as the core transmission element to simultaneously and precisely distribute the single action of the first unlocking component 220 to two different locking mechanisms (the first locking component 210 of the basket rack locking mechanism 200 and the rotating component locking mechanism 400). This "one-to-two" linkage design is ingenious, ensuring the synchronization of the two unlocking actions and avoiding the asynchronous or jamming problems that may occur due to step-by-step operation, resulting in high reliability of the action.

[0058] This application ingeniously achieves "one-way linkage." That is, operating the first unlocking component 220 (overall folding) will necessarily link the rotating component locking mechanism 400; however, operating the second unlocking component 420 (individual folding of the rotating component 300) will not affect the basket frame locking mechanism 200 at all. This logic is rigidly implemented through the mechanical structure, making the operation intuitive and less prone to errors, while ensuring that the stability of the basket frame 100 itself is not affected when the rotating component 300 is folded individually.
