Description

Technical Field

[0001] This application relates to the field of children's products technology, and in particular to a panel structure that can be used in products such as child seats, strollers, and high chairs. Background Technology

[0002] Traditional child car seats typically employ a multi-component modular structure, with core functional components such as the backrest, seat, and footrest assembled via hinges or rigid connections. This leads to the following drawbacks: First, the complex mechanical structure, with hinges, bolts, and other connecting parts increasing the number of parts, not only raises manufacturing costs but also makes them prone to reliability issues such as loose connections and abnormal noises during long-term use. Second, when folded up, the exposed hinge points can easily pinch fingers, and there are also issues such as a large storage volume. Summary of the Invention

[0003] The purpose of this application is to provide a foldable panel structure that, by controlling the number of cut groups, can achieve multiple functional forms such as two-section or three-section, providing an extended support surface in the flattened mode and enabling multi-functional use or compact storage in the folded mode.

[0004] The technical solution of this application is: a foldable plate structure, comprising:

[0005] The main body of the panel is formed integrally from polymer sheets;

[0006] At least one set of pre-cut marks is provided on the main body of the panel, the set of pre-cut marks dividing the main body of the panel into at least two adjacent sub-panel portions;

[0007] A fixing assembly is installed between each pair of adjacent sub-board sections;

[0008] The fixing component has a locked state and a released state; when the fixing component is in the locked state, it constrains adjacent sub-plate portions to be flat and coplanar; when the fixing component is in the released state, it allows adjacent sub-plate portions to be folded relative to each other around the pre-cut groove.

[0009] As one of the preferred technical solutions, the number of pre-cut marks is a set, which divides the main body of the plate into a first sub-plate part and a second sub-plate part.

[0010] The functional configuration of the first sub-board portion and the second sub-board portion includes any of the following combinations:

[0011] a) Seat panel + footrest extension panel;

[0012] b) Seat panel + backrest panel;

[0013] c) First part of the backrest panel + second part of the backrest panel;

[0014] d) Backrest section + headrest section.

[0015] As a preferred technical solution, the number of pre-cut marks is two sets, which divide the main body of the plate into a first sub-plate part, a second sub-plate part and a third sub-plate part along the length direction.

[0016] The first sub-board portion can be a backrest panel portion, the second sub-board portion can be a seat panel portion, and the third sub-board portion can be a footrest extension portion.

[0017] As a preferred technical solution, the fixing component can be a zipper or a fastening mechanism consisting of a strap and a buckle.

[0018] As a preferred technical solution, the pre-cut groove is a V-shaped groove or a U-shaped groove.

[0019] As a preferred technical solution, the depth of the pre-cut marks accounts for 70-90% of the thickness of the main body of the plate, and the reserved material is used as a flexible connection part.

[0020] As a preferred technical solution, the main body of the plate is made of polypropylene (PP) or high-density polyethylene (HDPE) sheet.

[0021] As a preferred technical solution, when the fixing component is in the loosened state, adjacent sub-plates are allowed to fold into an angle of 0-180°.

[0022] Compared with the prior art, this application has the following advantages:

[0023] 1. This application achieves two-section (such as seat / footrest, seat / backrest, etc.) or three-section (backrest / seat / footrest) or even four-section (backrest / seat / footrest / headrest) form conversion by controlling the number of cut groups. In the flat state, it seamlessly expands the bearing area to meet the needs of children lying down. In the folded state, it can flexibly switch to multi-part support (footrest support, backrest support, etc.) or minimalist storage form. One board covers all scenarios of sitting, lying down and storage, completely replacing the traditional multi-part assembly structure.

[0024] 2. In this application, each pair of adjacent sub-plates is locked or released by a fixing component, which is easy to operate (pull the zipper / buckle the strap) and the folding process is smooth. Attached Figure Description

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Example 1: As Figures 1 to 5 As shown, a foldable panel structure includes:

[0040] The main body 1 is formed integrally from polymer sheets;

[0041] At least one set of pre-cut marks 2 are provided on the main body of the plate, which divide the main body of the plate into at least two adjacent sub-plate portions 3;

[0042] A fixing assembly 4 is disposed between each pair of adjacent sub-plate portions 3;

[0043] The fixing component 4 has a locked state and a released state; when the fixing component 4 is in the locked state, it constrains the adjacent sub-plate portions 3 to be flat and coplanar; when the fixing component 4 is in the released state, it allows the adjacent sub-plate portions 3 to be folded relative to each other around the pre-cut groove 2.

[0044] In this embodiment, the number of pre-cut marks 2 is a set, which divides the main body of the plate into a first sub-plate part 3a and a second sub-plate part 3b.

[0045] The functional configuration of the first sub-board portion 3a and the second sub-board portion 3b includes any of the following combinations:

[0046] a) Seat panel + footrest extension panel; the seat surface can be flattened to lengthen it, and folded to form a leg rest or for storage.

[0047] b) Seat panel + backrest panel; when unfolded, it serves as a long seat cushion, and when released, the backrest can be folded up to serve as a support back panel or folded for storage.

[0048] c) Backrest panel first part + backrest panel second part; unfolded to form a complete backrest (long backrest), folded to adjust to a short backrest or for storage.

[0049] d) Backrest panel + headrest panel; flatten to extend backrest height; folds down for storage.

[0050] In this embodiment, the fixing component 4 can be a zipper 4a or a fastening mechanism 4b composed of a strap 4b1 and a buckle 4b2, etc. Since there are various types of fixing components 4 in the prior art, they will not be specifically described or limited here. The following only illustrates two specific implementations of the fixing component:

[0051] like Figure 1 and Figure 2 As shown, the fixing component 4 is a zipper 4a, which includes two sets of chain teeth 4a1 and 4a2 fixed to the edges of adjacent sub-plate portions (first sub-plate portion 3a and second sub-plate portion 3b) and a pull head 4a3 that engages with the two sets of chain teeth, and the zipper is opened and closed through the pull head 4a3.

[0052] like Figures 3 to 5As shown, the fixing component 4 is a fastening mechanism 4b consisting of a strap 4b1 and a buckle 4b2. One end of the strap 4b1 is fixed to an adjacent sub-plate portion (first sub-plate portion 3a) on one side, and the other end is detachably connected to an adjacent sub-plate portion (second sub-plate portion 3b) on the other side via the buckle 4b2. The buckle 4b2 can be a concealed buckle, including a buckle head 4b21 at the other end of the strap 4b1 and a buckle seat 4b22 on the adjacent sub-plate portion (second sub-plate portion 3b) on the other side. The locking of the buckle head 4b21 and the buckle seat 4b22 is determined by whether they are engaged or not.

[0053] In this embodiment, the pre-cut notch 2 is preferably a V-shaped groove or U-shaped groove with a depth of 70-90% of the thickness of the main body of the plate, and the reserved material is used as a flexible connection part.

[0054] In this embodiment, the main body 1 of the plate is preferably made of polypropylene (PP) or high-density polyethylene (HDPE) sheet.

[0055] In this embodiment, when the fixing component 4 is in the loosened state, adjacent sub-plate portions (first sub-plate portion 3a and second sub-plate portion 3b) are allowed to fold into an angle of 0-180°.

[0056] Example 2: The only difference from Example 1 is that the number of pre-cut marks is two sets, which divide the main body of the plate into a first sub-plate part, a second sub-plate part and a third sub-plate part along the length direction.

[0057] The first sub-board portion can be a backrest panel portion, the second sub-board portion can be a seat panel portion, and the third sub-board portion can be a footrest extension portion.

[0058] Example 3: The only difference from Example 1 is that the number of pre-cut marks is three sets, which divide the main body of the plate into the first sub-plate part, the second sub-plate part, the third sub-plate part and the fourth sub-plate part along the length direction.

[0059] The first sub-board portion can be a headrest portion, the second sub-board portion can be a backrest portion, the third sub-board portion can be a seat portion, and the fourth sub-board portion can be a footrest extension portion.

[0060] This application achieves two-section (such as seat / footrest, seat / backrest, etc.), three-section (backrest / seat / footrest), or even four-section (backrest / seat / footrest / headrest) form conversion by controlling the number of two sets of cuts. In the flat state, it seamlessly expands the bearing area to meet the needs of children lying down. In the folded state, it can flexibly switch to a multi-part support (footrest support, backrest support, etc.) or a minimalist storage form. One board covers all scenarios of sitting, lying down, and storage, completely replacing the traditional multi-part assembly structure.
