Description

Technical Field

[0001] This utility model belongs to the field of packaging box technology, specifically relating to a universal protective packaging structure. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In the automotive lighting manufacturing and supply chain sector, the packaging of small automotive lights (interior lights, door lights, side turn signals, sleeper lights, reading lights, marker lights, etc.) must meet the protection requirements during storage, transportation, and handling to prevent damage caused by squeezing, collisions, friction, etc. Current technologies for packaging small automotive lights often employ a customized "product size adaptation" solution. This involves designing a dedicated box and inner lining structure based on the specific dimensions (such as length, width, and height) of different lights, including the box's length, width, and height specifications, corrugated material selection, and inner lining partitioning methods.

[0004] Existing boxes often use single-corrugated or low-strength double-corrugated materials with the corrugation direction mostly horizontal (parallel to the bottom / top surface), resulting in weak load-bearing capacity and poor deformation resistance when stacked vertically. The pressure resistance of empty boxes is difficult to meet the requirements of multi-layer stacking. The internal lining or grid structure is simple, mostly consisting of flat partitions without cushioning or foam filling, lacking directional positioning design. During transportation, products are prone to displacement, mutual friction and collision. In addition, the gap between the box and the lining is unreasonable, failing to form effective collaborative protection, resulting in a high product damage rate. Utility Model Content

[0005] The purpose of this invention is to provide a universal protective packaging structure that can at least solve one of the above-mentioned technical problems.

[0006] To achieve the above objectives, embodiments of this utility model provide a universal protective packaging structure, including a box body and a grid disposed within the box body; the box body is made of double corrugated board, with the corrugation direction of the double corrugated board support surface being vertical; the grid includes multiple intersecting single corrugated boards, with the corrugation direction of the single corrugated board support surface being vertical, and the single corrugated board is provided with a U-shaped groove and a splicing interface, the single corrugated board being connected to the U-shaped groove through the splicing interface, dividing the internal space into multiple equal accommodating spaces.

[0007] Furthermore, a buffer layer is provided between the grille and the inner wall of the box.

[0008] Furthermore, the corrugation direction of both the double-corrugated board and the single-corrugated board is perpendicular to the bottom and top surfaces of the box.

[0009] Furthermore, multiple U-shaped grooves are evenly distributed along the side of the single corrugated plate, and the splicing interface is located at the end of the U-shaped groove.

[0010] Furthermore, the extension direction of the splicing interface is consistent with the vertical corrugation direction of the grille.

[0011] Furthermore, the double corrugated board is formed by combining a face paper, a first corrugated layer, a middle paper, a second corrugated layer, and a liner paper from the outside to the inside.

[0012] Furthermore, the single corrugated board is formed by a composite of a face paper, a second corrugated layer, and a liner paper from the outside to the inside.

[0013] Furthermore, the grille is fitted seamlessly with the interior of the housing.

[0014] Furthermore, a fitting gap is provided between the outer wall of the grille and the inner wall of the box.

[0015] Furthermore, product identification is provided on the outside of the box.

[0016] The beneficial effects of the above technical solutions are as follows: The box body of this utility model adopts a double corrugated plate with vertical corrugations and a grid made of single corrugated plates with vertical corrugations interlocked to form a longitudinal load-bearing frame, which improves the vertical compressive strength, meets the requirements of multi-layer stacking, and solves the problem of easy deformation of existing boxes.

[0017] The U-shaped grooves evenly distributed on the single corrugated sheet and their cooperation with the splicing interface achieve torsional reinforcement of the grille, ensuring a stable connection during transportation vibration; at the same time, the splicing of the single corrugated sheets evenly divides the space inside the box, effectively limiting product displacement and collision.

[0021] like Figures 1 to 5 As shown, this embodiment provides a universal protective packaging structure, including a box body 1 and a grid 2 disposed inside the box body 1; the box body 1 is made of double corrugated board, and the corrugation direction of the double corrugated board support surface is vertical; the grid 2 includes multiple intersecting single corrugated boards, and the corrugation direction of the single corrugated board support surface is vertical.

[0022] like Figure 1 As shown, a buffer layer is provided between the grid 2 and the inner wall of the box 1. When the box 1 is subjected to external impact, the buffer layer absorbs kinetic energy through its own compression deformation and converts part of the impact force into laterally dispersed stress. The single corrugated plate is provided with a U-shaped groove 3 and a splicing interface 4. The single corrugated plate is connected to the U-shaped groove 3 through the splicing interface 4, dividing the internal space into multiple equal accommodating spaces.

[0023] Specifically, the box body 1 uses double-corrugated panels with the corrugation direction perpendicular to the bottom surface. This ensures that the load is transferred along the corrugation direction during stacking, enhancing the vertical load-bearing capacity of the packaging box and effectively preventing deformation and collapse of the box body 1 when stacked in multiple layers. It also avoids the problem of easy crushing of the transverse corrugations. The single corrugated panels of the grille 2 also use vertical corrugations, forming a longitudinal support frame when they are cross-connected. After the splicing interface 4 is inserted into the U-shaped groove 3, the extension direction of the interface is consistent with the corrugation direction, ensuring that the splicing structure does not undergo lateral displacement when the connection is under force, and preventing the grille 2 components from loosening and failing under vibration. The grid formed by the intersection of multiple single corrugated panels divides the packaging space into equal units, reducing friction and collision caused by displacement during transportation. The lamps are confined to fixed positions to prevent shaking and collision during transportation.

[0024] like Figure 1 The corrugated directions of both the double-walled and single-walled sheets shown are perpendicular to the bottom and top surfaces of the box 1. When the bottom and top surfaces of the box 1 are subjected to vertical stacking loads, the perpendicular corrugated direction of the double-walled sheet can transfer the pressure along the corrugation direction to the sidewalls of the box 1, preventing the corrugated structure from bending and deforming under lateral pressure. The perpendicular corrugated direction of the single-walled sheet keeps the grid 2 upright when dividing the space. By forming a directional consistency with the perpendicular corrugated direction of the double-walled sheet, the box 1 and the grid 2 can work together to bear the pressure under vertical loads. The vertical corrugated structures of the box 1 and the grid 2 together form a continuous longitudinal support system, thereby eliminating the risk of collapse caused by the inconsistency between the force direction and the corrugation extension direction of the transverse corrugated structure.

[0025] like Figure 2 and Figure 3As shown, multiple U-shaped grooves 3 are evenly distributed along the side of the single corrugated sheet, and the splicing interface 4 is located at the end of the U-shaped groove 3. At least six sets of U-shaped grooves 3 are machined at fixed intervals along the side of the single corrugated sheet, with the distance between adjacent grooves equal to the standard size of the target partition space. When two single corrugated sheets intersect perpendicularly, the splicing interface 4 of one sheet is precisely embedded into the U-shaped groove 3 of the other sheet, forming a three-point positioning through the contact surface between the groove sidewall and the interface. Because the U-shaped grooves 3 are evenly distributed along the side, during cross-assembly, each connecting node forms equidistant support points, ensuring the overall grid 2 maintains a uniform mesh size. When the splicing interface 4 is located at the end of the U-shaped groove 3, its insertion depth is limited by the obstruction at the end of the groove, preventing over-insertion and structural deformation. Simultaneously, the two side walls of the U-shaped groove 3 form a wrapping clamp on the interface, enhancing the node's torsional resistance.

[0026] The extension direction of the interlocking interface 4 is consistent with the vertical corrugation direction of the grille 2. The parallel extension direction of the interlocking interface 4 ensures that the force direction of the interface coincides with the longitudinal compressive axis of the corrugated structure. When external pressure is applied to the grille 2, the interlocking surface of the interlocking interface 4 transfers the load through the continuous support of the vertical corrugations, preventing cracking of the interface due to lateral shear force. During transportation vibrations, energy is absorbed through the elastic deformation of the corrugated waves, while maintaining the geometric stability of the interlocking connection, thereby preventing product displacement caused by interface deformation. like Figure 4 As shown, the double-wall corrugated board is formed from the outside to the inside by a composite of face paper 7, first corrugated layer 5, middle paper 9, second corrugated layer 6, and liner paper 8. Specifically, a first corrugated layer 5 and a second corrugated layer 6 are bonded together with the face paper 7, middle paper 9, and liner paper 8 to form a composite board with bidirectional support capabilities. The first corrugated layer 5 uses the existing B-type corrugation, and the second corrugated layer 6 uses the existing C-type corrugation.

[0027] like Figure 5 As shown, the single corrugated board is formed by bonding the face paper 7, the second corrugated layer 6 and the inner paper 8 from the outside to the inside. The design of the single corrugated board by bending (cutting) perpendicular to the corrugation direction enables the grid 2 to effectively resist external compression and impact during transportation, reduce product displacement and collision risks, and improve the overall collaborative protection performance of the packaging structure.

[0028] The grille 2 and the box body 1 are internally fitted together, and the outer wall of the grille 2 and the inner wall of the box body 1 form a multi-point contact support structure. When the box body 1 is subjected to external impact, the contact surface converts the impact force into the joint deformation of the box body 1 and the grille 2, and the energy is dispersed through the vertical support characteristics of the corrugated structure. There is a fitting gap between the outer wall of the grille 2 and the inner wall of the box 1. When the box 1 is subjected to external impact during transportation, the grille 2 will adjust its position adaptively through the displacement space generated by the fitting gap. At this time, the impact energy is converted into the displacement energy of the grille 2 instead of being directly transferred to the internal product.

[0029] like Figure 3 As shown, product labels are set on the outside of box 1. By setting product labels on the outside of box 1, the classification of lamps can be completed directly through visual recognition during the logistics sorting process, and the product type and specifications can be confirmed without disassembling the packaging.

[0030] The working principle of this utility model: The housing 1 is made of double-corrugated sheet, and the grille 2 is composed of single-corrugated sheets intersecting each other. The corrugation direction of both housing 1 and grille 2 is perpendicular to the bottom surface of housing 1. When stacked, the vertical corrugations transmit pressure to the side walls along the corrugation direction, preventing lateral bending and improving vertical load-bearing capacity and collapse resistance. Grille 2 is connected by single-corrugated sheets with U-shaped grooves 3 and interlocking interfaces 4. The interface extension direction is consistent with the corrugation direction, forming a longitudinal support frame. When interlocked, the interface is embedded in the U-shaped groove 3 to form a three-point positioning. The groove wall wraps and clamps to enhance the torsional resistance of the node, ensuring a stable connection under vibration. At the same time, grille 2 divides the space into equal units, restricting product displacement; a buffer layer is set between housing 1 and grille 2, which absorbs kinetic energy and disperses stress through compression deformation when impacted.

[0031] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
