[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] See Figures 1 to 6 As shown, this utility model discloses a one-piece molded double-layer stepped charging cable box structure, comprising a box body 1, a first cover plate 2, and a second cover plate 3. The box body 1, the first cover plate 2, and the second cover plate 3 are formed by folding a single sheet of paper, eliminating multiple complex steps such as die-cutting, forming, and assembling the inner card and the color box separately. This simplifies the process, reduces manpower input, and thus reduces labor costs. Specifically, the box body 1, the first cover plate 2, and the second cover plate 3 are all made of F-corrugated cardboard.

[0025] The box body 1 has a cavity for the charging cable, and the box body 1 has a first step 4 and a second step 5 on its two sides respectively. The first cover plate 2 is connected to the side of the box body 1 near the first step 4 and abuts against the first step 4, and is used to close the lower half of the cavity to form the lower cavity. The second cover plate 3 is connected to the side of the box body 1 near the second step 5 and abuts against the second step 5, and is used to close the upper half of the cavity to form the upper cavity.

[0026] The lower cavity is formed by the first cover plate 2 and the first step 4 abutting against each other and sealing the lower half of the cavity, and the upper cavity is formed by the second cover plate 3 and the second step 5 abutting against each other and sealing the upper half of the cavity, which can be used to properly place the charging cable.

[0027] When in use, the box body 1, the first cover plate 2, and the second cover plate 3 are folded from a single sheet of paper to form the overall packaging structure.

[0028] After folding, a cavity for accommodating the charging cable is naturally formed inside the box 1. At this time, since the first step 4 and the second step 5 are respectively set on both sides of the box 1, and the first cover plate 2 is connected to the side of the box 1 near the first step 4, the first cover plate 2 is folded along the connection with the box 1 until the first cover plate 2 abuts against the first step 4, thus sealing the lower half of the cavity and forming the lower cavity.

[0029] Next, the second cover plate 3 is connected to the side of the box body 1 near the second step 5. The second cover plate 3 is folded along the connection with the box body 1 until the second cover plate 3 abuts against the second step 5, thereby sealing the upper half of the cavity and forming the upper cavity. At this point, the entire packaging structure is complete, and the charging cable can be properly placed in the upper and lower cavities for packaging.

[0030] See Figure 2 and Figure 3 As shown, the box body 1 in this embodiment includes a bottom sheet 11, a front sheet 12 and a rear sheet 13. The front sheet 12 is connected to the front end of the bottom sheet 11, and the rear sheet 13 is connected to the rear end of the bottom sheet 11, so that the front sheet 12 and the rear sheet 13 are respectively connected to the bottom sheet 11.

[0031] The first step 4 is located on the side of the film 11 near the front film 12, and the second step 5 is located on the side of the film 11 near the back film 13. The first step 4 is provided with a first clamping groove 41, and the left and right sides of the front piece 12 are provided with first inserts 121. The front piece 12 is bent along the connection between itself and the bottom piece 11, and the first inserts 121 are inserted into the first clamping groove 41. The contact surfaces of the first inserts 121 and the first clamping groove 41 generate friction, and the side wall of the first clamping groove 41 squeezes the first inserts 121, forming a mechanical engagement, thereby connecting the front piece 12 with the first step 4 and preventing the first inserts 121 from separating from the first clamping groove 41.

[0032] The second step 5 is provided with a second clamping groove 51, and the left and right sides of the rear piece 13 are provided with second inserts 131. The rear piece 13 is bent along its connection with the bottom piece 11, and the second inserts 131 are inserted into the second clamping groove 51. Similarly, the contact surfaces of the second inserts 131 and the second clamping groove 51 generate friction, and the sidewall of the second clamping groove 51 squeezes the second inserts 131, forming a mechanical engagement, thereby connecting the rear piece 13 with the second step 5, and preventing the first insert 121 from separating from the first clamping groove 41.

[0033] See Figure 2 As shown, in this embodiment, the height of the front piece 12 is lower than the height of the rear piece 13. This ensures that the height of the front piece 12 matches the height of the first step 4, and the height of the rear piece 13 matches the height of the second step 5. This allows the front piece 12 and rear piece 13 to form a precise fit and cooperative support with the first step 4 and the second step 5, respectively. This height matching ensures that the front piece 12 and the first step 4, and the rear piece 13 and the second step 5, can be quickly positioned and tightly fitted during assembly, reducing debugging time and labor costs during assembly. Simultaneously, this fit enhances the stability and sealing of the packaging structure, effectively preventing the charging cable from falling off or being damaged during transportation and storage.

[0034] See Figure 2 and Figure 3 As shown, in this embodiment, both the first step 4 and the second step 5 include a first stacked piece 100, a first crease line 101, and a second stacked piece 102; The first stack 100 is connected to both sides of the base film 11, the second stack 102 is connected to the side of the first stack 100 away from the base film 11, and the first crease line 101 is provided between the first stack 100 and the second stack 102. The film 11 is provided with a socket 111 at the connection between it and the first stack 100. The second stack 102 is provided with a strip 103. The second stack 102 is folded along the first fold line 101 to form a first clamping groove 41 and a second clamping groove 51. The strip 103 is inserted into the socket 111.

[0035] The first stacked sheet 100 connects to both sides of the base sheet 11 as a basic support. The second stacked sheet 102 is folded using the first fold line 101, thereby forming the first clamping groove 41 and the second clamping groove 51. At the same time, an insertion hole 111 is provided at the connection between the base sheet 11 and the first stacked sheet 100, and an insertion strip 103 is provided on the second stacked sheet 102. Through the insertion and cooperation of the insertion strip 103 and the insertion hole 111, the first step 4 and the second step 5 are stably formed and positioned. By replacing the traditional complex assembly method with a folding and insertion structure, the packaging production process is simplified, manual operation steps are reduced, and labor costs are lowered.

[0036] See Figure 4As shown, in this embodiment, both sides of the first cover plate 2 are connected to first abutment pieces 21. The first abutment pieces 21 are bent along their connection with the first cover plate 2 and abut against the inner side of the first step 4, the inner side of the second step 5, and the bottom piece 11. The bent first abutment pieces 21 abut against the inner side of the first step 4, the inner side of the second step 5, and the bottom piece 11 simultaneously to form a first bent abutment structure.

[0037] The first bending contact structure of the first abutting piece 21 enhances the stability of the connection between the first cover plate 2 and the box body 1, preventing the cover plate from loosening or detaching. Simultaneously, the first bending contact structure effectively disperses external pressure, improving the overall compressive strength and sealing of the packaging, ensuring reliable protection of the charging cable during transportation and storage. It also allows the first cover plate 2 to connect to the side of the box body 1 near the first step 4 and abut against the first step 4, thus sealing the lower half of the cavity to form a lower chamber.

[0038] See Figure 2 As shown, in this embodiment, the first cover plate 2 is provided with a first snap hole 22. The hole-like structure of the first snap hole 22 provides a force point for closing or opening the first cover plate 2, thereby enabling the first cover plate 2 to be closed or opened quickly.

[0039] See Figure 2 As shown, in this embodiment, the first cover plate 2 is provided with a second snap hole 23. The hole-like structure of the second snap hole 23 provides a force point for closing or opening the second cover plate 3, thereby enabling the second cover plate 3 to be closed or opened quickly.

[0040] See Figure 5 As shown, in this embodiment, the second cover plate 3 has second abutment pieces 31 connected to both sides. The second abutment pieces 31 are bent along their connection with the second cover plate 3 and abut against the inner side of the second step 5 and the first cover plate 2. By utilizing the bent second abutment pieces 31 to simultaneously abut against the inner side of the second step 5 and the first cover plate 2 to form a second bent abutment structure, the multi-directional mechanical constraint of the second bent abutment structure generates an interaction force between the second cover plate 3, the second step 5, and the first cover plate 2.

[0041] Meanwhile, the second bending contact structure of the second abutting piece 31 enhances the stability of the connection between the second cover plate 3 and the box body 1 and the first cover plate 2, effectively preventing the second cover plate 3 from loosening or detaching, and improving the overall sealing and compressive strength of the packaging; moreover, the second bending contact structure requires no additional parts or complex assembly steps, simplifying the production process and reducing labor costs. It also enables the second cover plate 3 to be connected to the side of the box body 1 near the second step 5 and to abut against the second step 5, thereby sealing the upper half of the cavity to form the upper cavity.

[0042] See Figure 6As shown, in this embodiment, the end of the second cover plate 3 furthest from the box body 1 is connected to a sealing piece 32. Both ends of the sealing piece 32 have third inserts 33. The sealing piece 32 is bent along its connection point with the second cover plate 3, and the third inserts 33 are inserted into the second clamping groove 51. The insertion and engagement of the third inserts 33 with the second clamping groove 51 forms an openable and closable mechanical locking structure. This mechanical locking structure allows the upper cavity to close quickly and achieve a secure seal.

[0043] See Figure 2 As shown, the sealing piece 32 in this embodiment is provided with a third fastening hole 34. The perforated structure of the third fastening hole 34 provides a force point for closing or opening the sealing piece 32, enabling rapid closing or opening of the sealing piece 32.
