[0002] Child seat slings, designed to support children while they sit or lie down, can be attached to various product racks to provide support. Current child seat slings typically consist of a backrest, seat frame, and footrest. Folding a child seat sling usually involves rotating the backrest relative to the seat frame to fold it down, followed by manually rotating the footrest relative to the seat frame to fold it back up relative to the backrest. This process is rather cumbersome and inconvenient. Summary of the Invention

[0003] The purpose of this application is to provide a foot-operated unlocking child seat that achieves efficient folding with a simple flip through the mechanical linkage between the foot pedal assembly and the seat cushion locking mechanism, while improving ease of use and comfort.

[0004] The technical solution of this application is: a foot-operated unlockable child seat, having an unfolded state and a folded state. The child seat includes a socket, a seat cushion assembly, a backrest assembly, and a footrest assembly. The seat cushion assembly and the backrest assembly are rotatably connected to the socket, and a backrest angle adjustment mechanism is provided between the backrest assembly and the socket. A seat cushion locking mechanism is provided between the seat cushion assembly and the socket. The footrest assembly is rotatably connected to the front side of the seat cushion assembly, and a footrest angle adjustment mechanism is provided between the two. A transmission component is provided between the footrest assembly and the seat cushion locking mechanism, and the child seat can release the seat cushion locking mechanism by flipping up the footrest assembly.

[0005] As a preferred technical solution, the seat cushion locking mechanism includes a locking member disposed within the seat cushion assembly and capable of sliding and extending relative to it, and a first reset member disposed between the locking member and the seat cushion assembly; the socket has a locking groove corresponding to the locking member; when the child seat is in use, the seat cushion locking mechanism achieves locking through the locking engagement of the locking member and the locking groove.

[0006] As a preferred technical solution, the transmission component is a traction cable, one end of which is connected to the locking member, and the other end of which is connected to the foot pedal assembly. The connection point between the traction cable and the foot pedal assembly is offset from the rotation center of the foot pedal assembly and the seat cushion assembly.

[0007] As a preferred technical solution, when the footrest assembly flips up around its rotation point with the seat cushion assembly until its front edge is higher than the upper surface of the seat cushion, the seat cushion locking mechanism is released via the transmission assembly. That is, when the footrest assembly is in the unlocked position, it is in an inclined state with the front higher than the back.

[0008] As a preferred technical solution, the foot pedal angle adjustment mechanism adopts a multi-position locking structure, which can selectively fix the pedal assembly at multiple preset positions during its rotation stroke.

[0009] As a preferred technical solution, the seat cushion assembly is rotatably connected to the footrest assembly via a seat cushion connecting seat thereon;

[0010] The footrest angle adjustment mechanism includes a locking gear, a first toothed groove formed on the seat connecting seat and corresponding to the locking gear, a second toothed groove formed on the footrest connecting seat and corresponding to the locking gear, a second reset member disposed between the locking gear and the footrest connecting seat or the seat connecting seat, and an unlocking button that can drive the locking gear to move and release the simultaneous locking of the seat assembly and the footrest assembly.

[0011] As a preferred technical solution, the backrest angle adjustment mechanism adopts a multi-position locking structure, which can selectively fix the backrest assembly at multiple preset positions during its rotation stroke.

[0012] As a preferred technical solution, the socket has a plug slot that can be grafted and installed on other product racks.

[0013] Compared with the prior art, this application has the following advantages: This application transforms the upward flipping action of the foot pedal assembly into the unlocking driving force of the seat locking mechanism. Through the mechanical linkage between the foot pedal assembly and the seat locking mechanism, it achieves efficient folding with "one flip and it folds", while improving the convenience and comfort of use. Compared with the prior art, it simplifies the folding operation steps and facilitates the user's daily use. Attached Figure Description

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] In the description of this application specification and claims, if there is a "direction" of motion, including motion with directional components, 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.

[0029] like Figures 1 to 6 As shown, a foot-operated unlockable child seat has an unfolded state and a folded state. The child seat includes a socket 1, a seat cushion assembly 2, a backrest assembly 3, and a footrest assembly 4. The seat cushion assembly 2 and the backrest assembly 3 are rotatably connected to the socket 1, and a backrest angle adjustment mechanism is provided between the backrest assembly 3 and the socket 1. A seat cushion locking mechanism 5 is provided between the seat cushion assembly 2 and the socket 1. The footrest assembly 4 is rotatably connected to the front side of the seat cushion assembly 2, and a footrest angle adjustment mechanism 6 is provided between the two. A transmission component 7 is provided between the footrest assembly 4 and the seat cushion locking mechanism 5. The child seat can release the seat cushion locking mechanism 5 by flipping the footrest assembly 4 upwards.

[0030] In this embodiment, the seat cushion locking mechanism 5 includes a locking member 501 disposed within the seat cushion assembly 2 and capable of sliding and extending relative to it, and a first reset member 502 disposed between the locking member 501 and the seat cushion assembly 2; the socket 1 has a locking groove 503 corresponding to the locking member 501; when the child seat is in use, the seat cushion locking mechanism 5 achieves locking through the locking engagement of the locking member 501 and the locking groove 503.

[0031] In this embodiment, the transmission component 7 is a traction cable, one end of which is connected to the locking member 501, and the other end is connected to the foot pedal assembly 4. The connection point between the traction cable and the foot pedal assembly 4 is offset from the rotation center of the foot pedal assembly 4 and the seat cushion assembly 2.

[0032] In this embodiment, when the footrest assembly 4 is flipped up around its rotation point with the seat cushion assembly 2 until its front edge is higher than the upper surface of the seat cushion 2, the seat cushion locking mechanism 5 is released via the transmission assembly 7. That is, when the footrest assembly 4 is in the seat cushion unlocked position, it is in an inclined state with the front higher than the back. This design ensures that when the footrest assembly 4 is adjusted in angle within its usage range, no accidental unlocking will occur.

[0033] In this embodiment, the foot pedal angle adjustment mechanism 6 adopts a multi-position locking structure, which can selectively fix the pedal assembly 4 at multiple preset positions during its rotation stroke.

[0034] Preferably, the seat cushion assembly 2 is rotatably connected to the footrest assembly 401 of the footrest assembly 4 via the seat cushion connecting seat 201 thereon; the footrest angle adjustment mechanism 6 includes a locking gear 601, a first toothed groove 602 formed on the seat cushion connecting seat 201 and corresponding to the locking gear 601, a second toothed groove 603 formed on the footrest connecting seat 401 and corresponding to the locking gear 601, a second reset member 604 disposed between the locking gear 601 and the footrest connecting seat 401 or the seat cushion connecting seat 201, and an unlocking button 605 that can drive the locking gear 601 to move and release the simultaneous locking of the seat cushion assembly 2 and the footrest assembly 4.

[0035] When the footrest angle adjustment mechanism 6 is in the locked state, the locking gear 601 is simultaneously engaged in the first tooth groove 602 and the second tooth groove 603. At this time, the locking gear 601 simultaneously locks the seat cushion assembly 2 and the footrest assembly 4, so that the two cannot rotate relative to each other.

[0036] When the footrest angle adjustment mechanism 6 needs to be unlocked to adjust the angle, press the unlock button 605 to push the locking gear 601, causing the locking gear 601 to exit the first tooth groove 602 or the second tooth groove 603. At this time, the locking gear 601 releases the simultaneous locking of the seat cushion assembly 2 and the footrest assembly 4, allowing the two to rotate relative to each other.

[0037] In this embodiment, the backrest angle adjustment mechanism adopts a multi-position locking structure, which can selectively fix the backrest assembly 3 at multiple preset positions during its rotation stroke. This backrest angle adjustment mechanism can be similar to the footrest angle adjustment mechanism described above, or it can be other existing angle adjustment mechanisms. Since the angle adjustment of the backrest assembly is not the focus of this application, specific examples and descriptions are not provided here, and it is not shown in the figures.

[0038] In this embodiment, the socket 1 has a plug slot 101 that can be grafted and installed on other product racks. This design is a conventional structure in the prior art, mainly to facilitate detachable assembly with other product racks (such as trolley racks), so specific examples and descriptions are not provided here.

[0039] The working principle of the folding motion in this application is as follows:

[0040] 1. Initial state

[0041] When the child seat is in the unfolded use state, the seat cushion assembly 2 is kept relatively fixed to the socket 1 by the seat cushion locking mechanism 5; the backrest assembly 3 is fixed at the required angle by the backrest angle adjustment mechanism; and the footrest assembly 4 is fixed at the required angle by the footrest angle adjustment mechanism 6 to support the child's feet.

[0042] 2. Footrest component 4 unlocks and flips up

[0043] Operate the foot pedal adjustment mechanism 6 (press the unlock button 605) to release the locked state of the foot pedal assembly 4; rotate the foot pedal assembly 4 upwards around the rotation point between it and the seat assembly 2.

[0044] When the footrest assembly 4 flips up around the point of rotation between itself and the seat cushion assembly 2 until its front edge is higher than the upper surface of the seat cushion 2, the locking member 501 of the seat cushion locking mechanism 5 is driven out of the locking groove 503 of the socket through the transmission assembly 7 (traction cable), thereby releasing the fixed connection between the seat cushion assembly 2 and the socket 1.

[0045] 3. Seat cushion assembly 2-fold

[0046] After the seat cushion locking mechanism 5 is unlocked, the seat cushion assembly 2 can rotate upwards (towards the backrest assembly 3) around its rotation point with the socket 1 until it is folded together with the backrest assembly 3. The backrest assembly 3 can always remain in use without needing to be rotated or folded.

[0047] This application transforms the upward flipping action of the foot pedal assembly 4 into the unlocking driving force of the seat locking mechanism 5. Through the mechanical linkage between the foot pedal assembly 4 and the seat locking mechanism 5, efficient folding with "one flip and fold" is achieved, while improving ease of use and comfort. Compared with the prior art, it simplifies the folding operation steps and facilitates the user's daily operation.
