[0001] This application belongs to the technical field of packaging, and particularly relates to a foldable plate member, a corner protector, and a packaging assembly. Background Art

[0002] During the transportation of products, it is necessary to package and protect the corners of the products to avoid collisions and damages during transportation.

[0003] Currently, corner protectors are mostly used in packaging to protect the corners of products. However, the existing corner protectors are generally made of materials such as plastics or foams, and the shapes of the corner protectors are fixed and cannot be folded. Therefore, they occupy a large amount of storage space and transportation space, resulting in high storage and transportation costs. Moreover, during the transportation of products, due to the poor support strength of the corner protectors, the corner protectors are prone to collapse or breakage and cannot protect the products, which is likely to cause damage to the products during transportation.

[0004] Therefore, the existing corner protectors have the defects of occupying a large amount of storage space and transportation space and being prone to collapse or breakage and unable to protect the products. Summary of the Utility Model

[0005] The purpose of the embodiments of this application is to provide a foldable plate member, a corner protector, and a packaging assembly, which can solve the problems in the related art that the corner protector occupies a large amount of storage space and transportation space and is prone to collapse or breakage and unable to protect the products.

[0007] A protective plate;

[0008] A first corner plate, the first edge of the first corner plate is connected to the first edge of the protective plate, and the first corner plate can be folded to form a first protective part with a first cavity;

[0009] A first reinforcing plate, the first reinforcing plate is connected to the second edge of the first corner plate, and the first reinforcing plate can be folded into the first cavity and connected to the cavity wall of the first cavity;

[0010] A second corner plate, the first edge of the second corner plate is connected to the second edge of the protective plate, the first edge and the second edge of the protective plate are adjacent, and the second corner plate can be folded to form a second protective part with a second cavity;

[0012] In a second aspect, an embodiment of the present application further provides a corner protector, which is formed by folding and assembling the above-mentioned foldable plate members. The corner protector includes:

[0013] A protective plate;

[0014] A first protective part, which is arranged on the protective plate. The first protective part is provided with a first cavity, and a first reinforcing plate is arranged in the first cavity. Two opposite edges of the first reinforcing plate are respectively connected to two opposite cavity walls of the first cavity;

[0015] A second protective part, which is arranged on the protective plate. The second protective part is connected to the first protective part, and the length direction of the first protective part intersects with the length direction of the second protective part. The second protective part is provided with a second cavity, and a second reinforcing plate is arranged in the second cavity.

[0036] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0037] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0038] Next, in conjunction with the accompanying drawings, the foldable plate member, corner guard, and packaging assembly provided in the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0039] Referring to Figures 1-7 , a foldable plate member provided in an embodiment of the present application can be folded and assembled into a corner guard. In this way, when storing or transporting the corner guard, the corner guard can be flattened into a plate-like structure, thereby greatly reducing the space occupied by the corner guard during transportation and storage, and reducing the storage or transportation cost of the corner guard.

[0040] Among them, the foldable plate member may include a guard plate 300, a first corner guard plate 101, and a second corner guard plate 201. The first edge of the first corner guard plate 101 may be connected to the first edge of the guard plate 300, and the first corner guard plate 101 can be folded into a first guard portion 100 having a first cavity 110. The first edge of the second corner guard plate 201 may be connected to the second edge of the guard plate 300, and the second corner guard plate 201 can be folded to form a second guard portion 200 having a second cavity 210. In this way, when using the corner guard, the first cavity 110 and the second cavity 210 can provide a buffer space so that the corner guard can better protect the product.

[0041] The foldable plate member may further include a first reinforcing plate 400 and a second reinforcing plate 500. The first reinforcing plate 400 may be connected to the second edge of the first corner guard plate 101. The second reinforcing plate 500 may be folded into the first cavity 110 and connected to the cavity wall of the first cavity 110. The second reinforcing plate 500 may be connected to the second edge of the second corner guard plate 201. The second reinforcing plate 500 may be folded into the second cavity 210 and connected to the cavity wall of the second cavity 210. In this way, the first reinforcing plate 400 and the second reinforcing plate 500 can respectively support and strengthen the first protection part 100 and the second protection part 200, thereby improving the overall strength and compressive resistance of the corner guard. When the impact force or pressure on the corner guard is large, it is not easy to bend and collapse, and thus can play a role in protecting the product during the transportation of the product.

[0042] In an alternative embodiment, the foldable plate member may be made of cardboard. In this way, compared with corner guards made of materials such as plastic or foam, it is more environmentally friendly and the foldable plate member can be reused.

[0043] Optionally, the guard plate 300 may be provided protruding from the first protection part 100 and the second protection part 200. The part of the guard plate 300 protruding from the first protection part 100 and the second protection part 200 may form a corner guard groove between the first protection part 100 and the second protection part 200. In this way, when the corner of the product is embedded in the corner guard groove, the first protection part 100, the second protection part 200 and the guard plate 300 can all play a role in protecting the corner of the product, thereby improving the protection performance of the corner guard for the product. Of course, the guard plate 300 may also not be provided protruding from the first protection part 100 and the second protection part 200.

The first protrusion 410 may be inserted into the first slot 141. In this way, the connection strength between the first protection part 100 and the first reinforcing plate 400 can be improved, and thus the overall strength of the corner guard can be improved.

[0045] A second protrusion 510 may be provided on one of the second reinforcing plate 500 and the second corner guard plate 201, and a second slot 241 may be provided on the other. The second protrusion 510 may be inserted into the second slot 241. In this way, the connection strength between the second protection part 200 and the second reinforcing plate 500 can be improved, and thus the overall strength of the corner guard can be improved.

Moreover, the first outer plate 130, the first top plate 140, the first inner plate 150, and the first bottom plate 160 may be folded in sequence to form the first protective part 100. In this way, the structure of the first protective part 100 can be simplified, and the structural strength of the first protective part 100 can be further improved. Here, the first reinforcing plate 400 may be connected to the first bottom plate 160, facilitating the folding of the first reinforcing plate 400 into the first cavity 110.

[0048] The second corner guard plate 201 may include a second outer plate 230, a second top plate 240, a second inner plate 250, and a second bottom plate 260 connected in sequence.

[0050] In addition, the first outer plate 130 and the guard plate 300 can be of an integral structure, and the first reinforcing plate 400 and the first bottom plate 160 can be of an integral structure. In this way, the structure of the corner guard can be simplified, and the structural strength of the corner guard can be improved. Of course, the first outer plate 130 and the guard plate 300 may not be of an integral structure, and the first reinforcing plate 400 and the first bottom plate 160 may not be of an integral structure either.

[0051] The second outer plate 230 and the guard plate 300 can be of an integral structure, and the second reinforcing plate 500 and the second bottom plate 260 can be of an integral structure.

In this way, after the first reinforcing plate 400 is folded, it can be located on the diagonal plane of the first cavity 110. Furthermore, the first protection part 100 can form two triangular structures to provide stable support and structural strength, and the first reinforcing plate 400 can effectively disperse and transfer forces, enhancing the overall stability and load-bearing capacity. Of course, the first slot 141 may not be disposed between the first top plate 140 and the first inner plate 150. Specifically, the first slot 141 can be disposed on the first top plate 140 or the first inner plate 150.

[0053] The second convex portion 510 can be disposed on the edge of the second reinforcing plate 500 facing away from the second bottom plate 260, and the second slot 241 can be disposed between the second top plate 240 and the second inner plate 250. In this way, after the second reinforcing plate 500 is folded, it can be located on the diagonal plane of the second cavity 210. Furthermore, the second protection part 200 can form two triangular structures to provide stable support and structural strength, and the second reinforcing plate 500 can effectively disperse and transfer forces, enhancing the overall stability and load-bearing capacity. Of course, the second slot 241 may not be disposed between the second top plate 240 and the second inner plate 250.

The connecting convex portion 220 may be embedded in the connecting groove 120, and the connecting convex portion 220 and the connecting groove 120 may be in limiting cooperation. In this way, through the connection of the connecting convex portion 220 and the connecting groove 120, the connection area between the first protection portion 100 and the second protection portion 200 can be increased, and the separation of the connecting convex portion 220 and the connecting groove 120 can be avoided through the limiting cooperation between the connecting convex portion 220 and the connecting groove 120. Furthermore, the connection stability between the first protection portion 100 and the second protection portion 200 can be improved, which is beneficial to improving the overall support and structural strength of the corner protector.

[0055] In other embodiments, neither the connecting convex portion 220 nor the connecting groove 120 may be provided on the first top plate 140 and the second top plate 240.

And, in the direction from the second connecting groove 122 to the first connecting groove 121, the second connecting portion 222 and the second connecting groove 122 are in limiting cooperation, that is, in the connection direction of the first protection portion 100 and the second protection portion 200, the second connecting portion 222 and the second connecting groove 122 are in limiting cooperation. In this way, the disconnection between the first protection portion 100 and the second protection portion 200 can be avoided, and further, the connection stability between the first protection portion 100 and the second protection portion 200 can be improved.

[0057] Here, the size of the second connecting portion 222 may be larger than the size of the first connecting portion 221, and the size of the second connecting portion 222 may be larger than the size of the first connecting groove 121.
