Description

Technical Field

[0001] This utility model relates to the technical field of vehicle frame packaging, and in particular to a shockproof packaging structure specifically for subframes. Background Technology

[0002] The subframe is a core load-bearing component of the automotive chassis system. It is usually made of stamped metal sheets and welded together. Its structure is an irregular frame shape with multiple mounting holes on the surface for connecting the suspension and engine. Some areas are thin-walled structures, which are easily scratched, deformed in the mounting holes, or dented in the thin-walled areas due to collisions and friction during transportation. This can affect the subsequent assembly accuracy with the automotive chassis and even lead to the scrapping of the subframe. Therefore, the transportation packaging of the subframe has extremely high requirements for protection.

[0003] When transporting subframes, in order to make full use of the space in the transport vehicle and reduce the high transportation costs, multiple subframes are usually stacked and packaged. The subframes are stacked layer by layer on the pallet and secured with stretch film. In order to avoid direct contact between the metal surfaces of adjacent subframes during transportation, separators (such as wooden partitions or plastic blocks) are usually set between the subframes to achieve separation and support functions. However, the assembly process of independent partition structures is complex, requiring a large number of partition clips, some of which need to be cut and customized. Additional bolts, tape, and other connectors are needed for fixing, which not only increases the packaging process, but also requires the removal of each connector during subsequent disassembly, affecting unloading efficiency. Furthermore, traditional partition clips (such as wooden partitions) have no cushioning performance. Although they can achieve physical separation, the subframe is prone to surface scratches or deformation of thin-walled areas when colliding with the partition due to hard contact, which cannot meet the core requirement of anti-collision.

[0004] To address this issue, we propose a dedicated anti-collision packaging structure for subframes. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a special anti-collision packaging structure for subframes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A shockproof packaging structure specifically for subframes includes multiple sets of shelves, which are stacked vertically to form a main packaging body for storing the subframe, and further includes: A detachable partition and a set of support plates, wherein the set of support plates is inserted into the partition and the two are perpendicular to each other. After the support plates and the partition are spliced ​​together, they form a partition frame to divide the placement space on the upper part of the shelf. A protective assembly that provides protection for the subframe includes a set of pads, pads and a protective plate, wherein the pads and pads are disposed on the upper surface of the shelf and the protective plate is disposed on the lower surface of the shelf; A set of positioning perforations made on the shelf.

[0007] Preferably, the upper and lower surfaces of the shelf are provided with positioning frames adapted to the partition, and the upper and lower ends of the partition are respectively inserted into the positioning frames of the upper and lower side shelves.

[0008] Preferably, the sidewalls of the partition and the support plate are covered with a composite EVA material layer, and the pads, pads and protective plates are all made of composite EVA material.

[0009] Preferably, the side walls of the support plate and the partition are provided with matching sockets, and the support plate and the partition are spliced ​​together through the sockets.

[0010] Preferably, the upper surface of the pad is an arc-shaped structure, which is used to fit the outer wall of the subframe. The pad and the pad plate cooperate to form a support and positioning structure for the subframe.

[0011] Preferably, the protective plate is staggered with the pads and pads on the lower end face of the adjacent upper layer.

[0012] Preferably, after multiple sets of the aforementioned layers are stacked, the positioning holes of each set of layers are coaxially distributed, and a fixing member for positioning multiple sets of layers is inserted into the positioning holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model simplifies the assembly process through the positioning frame and splicing design. The partition can be directly inserted into the positioning frame of the shelf without additional connecting parts. The support plate and the partition can be quickly spliced ​​together to form a partition frame through the matching splice. The entire assembly process does not require tools, and a single person can complete the assembly of the shelf partition structure, reducing the number of partition clips used, improving the overall assembly efficiency, and thus shortening the overall cycle of subframe packaging and unloading. The side walls of the partitions and support plates are covered with a layer of composite EVA material. The pads, pads, and protective plates are all made of composite EVA material. The elastic cushioning properties of EVA material can effectively absorb the vibration and impact during transportation, preventing hard contact between the subframe and the packaging structure. At the same time, the arc-shaped pads can fit tightly against the outer wall of the subframe, which not only improves positioning stability but also disperses the pressure of the subframe on the packaging structure, so that the subframe remains stable during transportation and avoids collisions with the packaging structure.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A shockproof packaging structure specifically for subframes includes multiple sets of shelves 1, made of high-strength corrugated cardboard or polypropylene plastic sheets. The multiple sets of shelves 1 are stacked vertically to form the main packaging body for storing the subframe. It also includes: The shelf 2 is removable and consists of a set of support plates 3. Both the sidewalls of the shelf 2 and support plates 3 are covered with a composite EVA material layer. The shelf 2 and support plates 3 are made of rigid plastic sheets, and the sidewalls are covered with the composite EVA material layer using an adhesive bonding process. EVA (ethylene-vinyl acetate copolymer) is a soft, elastic, and cushioning polymer material. Common characteristics include lightweight, impact resistance, abrasion resistance, and scratch resistance; it is also non-corrosive to most products. Positioning frames 101, adapted to the shelf 2, are provided on both the top and bottom surfaces of the shelf 1. The partition 2 has a rectangular groove structure. The upper and lower ends of the partition 2 are inserted into the positioning frames 101 of the upper and lower side panels 1, respectively. A set of support plates 3 are inserted into the partition 2 and are perpendicular to each other. The side walls of the support plates 3 and the partition 2 are provided with matching slots 301. The support plates 3 and the partition 2 are spliced ​​through the slots 301. After the support plates 3 and the partition 2 are spliced, they form a partition frame, which divides the placement space on the upper side of the panel 1, realizes the independent positioning of multiple sub-frames on a single panel 1, and avoids collisions between sub-frames. At the same time, the support plates 3 and the partition 2 are in a cross shape. The support plates 3 support the partition 2. The two work together to expand the support area to support the upper panel 1, thereby improving stability. The protective components that provide protection for the subframe include a set of pads 4, pads 5, and protective plates 6. The pads 4 and pads 5 are set on the upper surface of the shelf 1. The upper surface of the pads 4 has an arc-shaped structure to fit the outer wall of the subframe. The radius of the arc is designed according to common subframe models. In combination with the structure of the subframe, it forms a "wrap-around" support to prevent the subframe from sliding laterally during transportation and to make it more stable. The pads 4 and pads 5 work together to form a support and positioning structure for the subframe. The two are combined to prevent the mounting holes and protruding structures at the bottom of the subframe from making hard contact with the shelf 1, providing a positioning and protection effect for the subframe and preventing it from shifting or shaking and causing collisions with the internal structure. The protective plate 6 is set on the lower surface of the shelf 1. The protective plate 6 is staggered with the pads 4 and pads 5 on the lower surface of the adjacent shelf 1 on the upper side. The pads 4, pads 5, and protective plates 6 are all made of composite EVA material. A set of positioning perforations 7 are formed on the shelf 1. After multiple sets of shelves 1 are stacked, the positioning perforations 7 of each set of shelves 1 are coaxially distributed. Fixing members for positioning multiple sets of shelves 1 are inserted into the positioning perforations 7. Wear-resistant plastic rings are pasted on the inner wall to prevent the shelf 1 from being worn when the fixing members are pulled. Under the action of the fixing members, the relative stability between different shelves 1 is ensured, and the situation of unstable packaging structure and loosening is avoided. The fixing members can be simple ropes or telescopic fixing rods, etc., and different choices can be made according to the actual situation.

[0021] Based on the above structure, the present invention has the following embodiments: In use, place a set of shelves 1 horizontally in the center of the tray. According to the position of the subframe, lay the pads 4 and pads and fix them with adhesive. Insert the partition 2 into the positioning frame 101 of the bottom shelf 1. Align the insertion port 301 of the support plate 3 with the insertion port 301 of the partition 2 and push it vertically until the insertion port 301 is completely attached. Then lift or manually place the subframe onto the shelf 1 so that the bottom of the subframe is completely attached to the pads 4 and pads 5. Then stack other shelves 1 on the top. According to the position of the subframe, attach and fix the protective plate 6. According to the assembly method of the bottom protective components, install the pads 5 and pads 4 on the upper surface of the upper shelf 1. Then build the partition frame and place the subframe. Repeat the above steps until all subframes are stacked in layers. Check whether the positioning holes 7 of all shelves 1 are coaxially aligned. Pass the fasteners through the positioning holes 7 of all shelves 1 to complete the overall fixation.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
