[0045] Embodiment 1:

[0046] As Figures 1-6 shown, this embodiment provides a packaging assembly, which includes several packaging corner guards 100 and a box body 200. The packaging corner guards 100 are arranged on the inner wall of the box body 200. Specifically, as Figure 1 shown, one packaging corner guard 100 is provided at each of the four inner corners of the box body 200 to protect the corners of the goods. In this embodiment, the packaging assembly is used for packaging portable energy storage power supplies.

[0047] Furthermore, the packaging corner guard 100 is an integrally formed structure. The packaging corner guard 100 includes a base plate 10, a first corner guard structure 20, a second corner guard structure 30 and a locking structure. Among them, the first corner guard structure 20 and the second corner guard structure 30 are respectively connected to opposite sides of the base plate 10. The first corner guard structure 20 and the second corner guard structure 30 are both formed by folding. The first corner guard structure 20 presses the second corner guard structure 30 against the side surface of the base plate 10. One end of the locking structure is connected to the first corner guard structure 20, and the other end of the locking structure is connected to the base plate 10 or the second corner guard structure 30 to keep the second corner guard structure 30 in a state of pressing against the base plate 10.

[0048] Specifically, the packaging corner guard 100 provided in this embodiment is an integrally formed overall structure. Through folding, the first corner guard structure 20 and the second corner guard structure 30 are formed on one side of the base plate 10. Under the action of the locking structure, the first corner guard structure 20 keeps pressing the second corner guard structure 30 against the base plate 10, forming a corner guard structure with good stability and protection performance. During production, the operator only needs to fold to form the first corner guard structure 20 and the second corner guard structure 30, then press the second corner guard structure 30 against the base plate 10 through the first corner guard structure 20, and finally fix it through the locking structure, without using adhesives, achieving the effects of integral forming and fixing, simplifying the production process, and meeting the environmental protection requirements of being harmless, pollution-free and recyclable.

[0049] Exemplarily, the packaging corner guard 100 is integrally formed by folding and cutting high-strength cardboard or plastic sheets. The high-strength cardboard can be kraft paper, multi-layer corrugated paper or cardboard, ensuring that the packaging corner guard 100 has sufficient toughness, strength and durability.

[0050] Exemplarily, as Figure 3 shown, the first corner protection structure 20 is a quadrangular prism structure, including a first vertical surface 21, a first parallel surface 22, a first inclined surface 23 and a first abutting surface 24 connected in sequence. The first vertical surface 21 is vertically connected to the first side of the substrate 10, the first parallel surface 22 is parallel to the substrate 10, the first abutting surface 24 is parallel and abuts against the substrate 10, and one side of the first abutting surface 24 away from the first inclined surface 23 abuts against the first vertical surface 21. The second corner protection structure 30 is a triangular prism structure, including a second vertical surface 31, a second inclined surface 32 and a second abutting surface 33 connected in sequence. The second vertical surface 31 is vertically connected to the second side of the substrate 10, the second abutting surface 33 is parallel and abuts against the substrate 10, and one side of the second abutting surface 33 away from the second inclined surface 32 abuts against the second vertical surface 31. Both the first inclined surface 23 and the second inclined surface 32 are arranged at an angle with the substrate 10, and the first inclined surface 23 is parallel to the second inclined surface 32. The first inclined surface 23 presses against the second inclined surface 32 to achieve the effect that the first corner protection structure 20 presses the second corner protection structure 30 against the side surface of the substrate 10.

[0051] Specifically, the first corner protection structure 20 and the second corner protection structure 30 respectively form a stable corner protection structure. The first parallel surface 22 and the second inclined surface 32 are arranged towards the goods side, and the goods can abut against the first parallel surface 22 and the second inclined surface 32. When the first parallel surface 22 is pressed, the pressure is transmitted to the second inclined surface 32 and the first abutting surface 24 through the first inclined surface 23. On the one hand, the second inclined surface 32 is squeezed by the first inclined surface 23, and the second corner protection structure 30 is further pressed tightly on the substrate 10, strengthening the self-locking of the packaging corner protector 100 and making the structure more stable. On the other hand, one side of the first abutting surface 24 presses against the inner side surface of the first vertical surface 21, and the first corner protection structure 20 can bear a large load without deformation. When the second inclined surface 32 is pressed, on the one hand, the second corner protection structure 30 is further pressed tightly on the substrate 10, strengthening the self-locking of the packaging corner protector 100 and making the structure more stable. On the other hand, one side of the second abutting surface 33 presses against the inner side surface of the second vertical surface 31, and the second corner protection structure 30 can bear a large load without deformation.

[0052] Exemplarily, as Figures 3-5 shown, the second corner protection structure 30 further includes a spacer surface 34. One side of the spacer surface 34 is connected to the side of the second abutting surface 33 away from the first inclined surface 23, and the other side of the spacer surface 34 abuts against the second inclined surface 32, so that the first sub-triangular structure and the second sub-triangular structure are formed at intervals inside the second corner protection structure 30, further improving the structural stability of the second corner protection structure 30. When the second inclined surface 32 is pressed, the spacer surface 34 supports the inner side of the second inclined surface 32, improves the bearing capacity of the second inclined surface 32, and reduces the deformation amount of the second inclined surface 32.

[0053] Preferably, as Figure 3As shown, the cross-section of the second corner protection structure 30 is an isosceles right triangle. The spacer surface 34 is perpendicular to the second inclined surface 32, and the spacer surface 34 presses against the midline position of the second inclined surface 32.

[0054] Exemplarily, as Figures 3-5 shown, the second corner protection structure 30 further includes a third abutting surface 35. The third abutting surface 35 is parallel to and abuts against the second inclined surface 32. One side of the third abutting surface 35 is connected to the side where the spacer surface 34 abuts against the second inclined surface 32, and the other side of the third abutting surface 35 abuts against the second vertical surface 31. Specifically, the third abutting surface 35 abuts against the inner side of the second inclined surface 32, increasing the thickness of the bearing surface of the second corner protection structure 30, and the load can be transferred to the second vertical surface 31, further improving the bearing capacity of the second corner protection structure 30.

[0055] In this embodiment, as Figures 2-5 shown, the locking structure includes a tongue 41. One end of the tongue 41 is connected to the end of the first corner protection structure 20, and the other end of the tongue 41 is inserted into the gap between the first corner protection structure 20 and the second corner protection structure 30 and the substrate 10. Specifically, two tongues 41 are symmetrically arranged. The two tongues 41 are respectively connected to both ends of the first parallel surface 22. The tongue 41 is formed by bending. The tongue 41 is inserted into the gap between the first abutting surface 24 and the second abutting surface 33 and the substrate 10. The second abutting surface 33 can press the tongue 41 against the inner side surface of the substrate 10 under the action of the first corner protection structure 20 to realize the self-locking of the packaging corner protector 100.

[0056] Exemplarily, as Figure 2 and Figure 4 shown, an avoidance space is formed at the ends of the first corner protection structure 20 and the second corner protection structure 30. The avoidance space is used to avoid the tongue 41 so that the tongue 41 is flush with the end of the substrate 10 in height. Specifically, as Figure 2 and Figure 4 shown, the tongue 41 covers the ends of the first parallel surface 22, the first inclined surface 23, the first abutting surface 24, the second inclined surface 32, the second abutting surface 33, the spacer surface 34 and the third abutting surface 35. The heights of the first parallel surface 22, the first inclined surface 23, the first abutting surface 24, the second inclined surface 32, the second abutting surface 33, the spacer surface 34 and the third abutting surface 35 are smaller than the heights of the substrate 10, the first vertical surface 21 and the second vertical surface 31, so that an avoidance space is formed at both ends, enabling the packaging corner protector 100 to be stably placed vertically in the box 200, and the two ends will not bulge, with a compact structure.

[0057] Exemplarily, as Figures 4-6As shown, a plurality of creases are provided on the first corner protection structure 20 and the second corner protection structure 30. The first corner protection structure 20 and the second corner protection structure 30 are respectively formed by folding along the creases thereon. The creases form clear boundaries, and operators can fold the corner protection structure with more accurate and standard shapes based on this, ensuring the stability and reliability of the structure. Specifically, crease one 1, crease two 2, crease three 3, crease four 4, crease five 5, crease six 6, crease seven 7, crease eight 8, and crease nine 9 are provided at parallel intervals along the main body extension direction when the packaging corner protector 100 is unfolded. Taking upward folding as a positive crease and downward folding as a negative crease, among them, crease one 1 is a negative crease, and crease two 2, crease three 3, crease four 4, crease five 5, crease six 6, crease seven 7, crease eight 8, and crease nine 9 are all positive creases. When folding, on one side of the packaging corner protector 100, fold along crease one 1, crease two 2, crease three 3, crease four 4, and crease five 5 to form the second corner protection structure 30. On the other side of the packaging corner protector 100, fold along crease six 6, crease seven 7, crease eight 8, and crease nine 9 to form the first corner protection structure 20. The first corner protection structure 20 and the second corner protection structure 30 jointly form a plurality of mutually supporting triangular structures, with high structural stability.

[0058] Exemplarily, a plurality of creases are provided on the buckle structure, and the buckle structure is formed by folding along the creases thereon. Specifically, as Figure 4 and Figure 5 shown, a crease eleven 11 is provided between the tongue 41 and the first parallel surface 22, and a crease twelve 12 is provided on the tongue 41. Both crease eleven 11 and crease twelve 12 are positive creases. The tongue 41 is bent along crease eleven 11 and folded along crease twelve 12 to form a covering portion covering the ends of the first corner protection structure 20 and the second corner protection structure 30 and a plugging portion inserted between the first abutting surface 24, the second abutting surface 33, and the substrate 10.

[0059] Exemplarily, before folding the packaging corner protector 100, a high-strength cardboard or plastic sheet is cut using a laser cutting machine or a precision die to form a prefabricated board, and then a creasing machine is used to press clear creases along the predetermined folding lines to ensure accurate alignment during folding to form a stable corner protection structure.

[0060] Embodiment Two:

[0061] As Figure 7 and Figure 8 shown, in this embodiment, another packaging corner protector 100 is provided on the basis of Embodiment One. The difference between it and Embodiment One is that:

[0062] The insertion tongue 41 is not provided at the end of the first corner protection structure 20, and no avoidance space is formed at the ends of the first corner protection structure 20 and the second corner protection structure 30. One end of the insertion tongue 41 is connected to one of the first corner protection structure 20 and the second corner protection structure 30. The locking structure further includes a jack 42 which is provided in the other of the first corner protection structure 20 and the second corner protection structure 30, and the other end of the insertion tongue 41 is inserted into the jack 42.

[0063] Specifically, the insertion tongue 41 is formed at the junction of the first parallel surface 22 and the first inclined surface 23 by cutting the first inclined surface 23. One end of the insertion tongue 41 is connected to the first parallel surface 22. The jack 42 is formed by cutting in the middle of the second inclined surface 32. The other end of the insertion tongue 41 is inserted into the jack 42 and penetrates into the second corner protection structure 30. The end of the insertion tongue 41 penetrating into the second corner protection structure 30 forms a large end portion, and the width of the large end portion is greater than the width of the jack 42, so as to keep the insertion tongue 41 in a plugged state with the jack 42.

[0064] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
