DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0035] Embodiment one

[0036] Please refer to Figures 1-10

[0037] The present embodiment provides a turnover enclosure box for automobile parts, which comprises a box body, the box body comprising an upper cover 1, two sheet metal frameworks 3, a hollow enclosure 4, a bottom plate 6 and a lower cover 8, as shown in the figure, the two sheet metal frameworks 3 are respectively fixedly installed on the opposite side walls of the upper cover 1 and the lower cover 8 through countersunk head screws, the upper cover 1 plays a pressure-bearing and covering role, and the lower cover 8 plays a pressure-bearing and covering role. Figure 1

[0038] The sheet metal framework 3 is bent into a rectangular structure by square steel, and four butt joint seats 31 distributed in a rectangular structure are welded on the side wall of each sheet metal framework 3 away from the other, the two sheet metal frameworks 3 are respectively arranged at the upper and lower ends of the hollow enclosure 4, and a notch for clamping the edge bead of the hollow enclosure 4 is formed on the butt joint seat 31 of the sheet metal framework 3, as shown in the figure. Figure 3 The butt joint seat 31 welded on the sheet metal framework 3 is the main load-bearing part of the entire box body, playing a pressure-bearing role and dispersing the load to the upper cover 1, the hollow enclosure 4 and the lower cover 8.

[0039] ​The base plate 6 is located at the bottom of the inner side of the hollow enclosure 4. L-shaped support blocks 7 are fixed on both sides of the upper surface of the base plate 6. The base plate 6 is used to support automotive parts.

[0040] After fixing the lower sheet metal frame 3 to the upper end face of the lower cover 8, the lower side edge of the hollow partition plate 4 is inserted into the notch of the docking seat 31 of the lower sheet metal frame 3. Alternatively, countersunk screws can be used to fix the hollow partition plate 4 to the docking seat 31 of the lower sheet metal frame 3. Then, the base plate 6 is placed at the bottom of the inner side of the hollow partition plate 4 to support the automotive parts. The hollow partition plate 4 serves as a protective part for the four sides of the automotive parts. Then, the upper sheet metal frame 3 is fixed to the upper cover 1. Subsequently, the notch of the docking seat 31 of the upper sheet metal frame 3 is inserted into the upper side edge of the hollow partition plate 4. Alternatively, countersunk screws can be used to fix the hollow partition plate 4 to the docking seat 31 of the upper sheet metal frame 3. The automotive parts can then be stored in the box for easy handling.

[0041] The box structure described above maintains the same packaging shape and net internal dimensions, making it easy to replace or use with existing packaging.

[0042] The upper cover 1, lower cover 8, hollow partition 4, and bottom plate 6 are all made of EPP high-strength foam material, which makes the overall weight of the final assembled box lighter, achieving the purpose of weight reduction. While keeping the load capacity the same, the weight reduction and cost reduction are achieved, avoiding heavy packaging. The boxes containing automotive parts can be handled and transported by a single person, improving the turnover efficiency of automotive parts production.

[0043] Both sides of the hollow enclosure panel 4 and the L-shaped support block 7 are equipped with detachable buffer components 12, which are hollow rubber airbags. Figure 2 As shown, the hollow rubber airbag has elastic cushioning characteristics. When the car parts are placed inside the hollow panel 4 and sit on the base plate 6, the hollow rubber airbag acts as a buffer medium to buffer the collision force during the handling of the car parts, protecting the car parts from irreversible deformation or scratches that may cause paint damage.

[0044] like Figures 6-7 As shown, rectangular through holes are provided on both sides of the hollow enclosure 4 and the L-shaped support block 7. The hollow rubber airbag has a waist-shaped structure. The side wall of the hollow rubber airbag is fixed with a plug post 122, and the end of the plug post 122 is rotatably provided with a rotating handle 123. The side wall of the hollow rubber airbag rests against the inner side wall of the hollow enclosure 4. The plug post 122 is inserted into the rectangular through hole, and the rotating handle 123 passes through the rectangular through hole. Then the rotating handle 123 rotates around the plug post 122 as the rotation center until the rotating handle 123 and the rectangular through hole are misaligned. In this way, the buffer 12 can be set on the inner side wall of the hollow enclosure 4.

[0045] Conversely, rotate the handle 123 in the opposite direction until it is parallel to the rectangular through hole. Then, pass the handle 123 through the rectangular through hole to disengage the plug post 122 from the rectangular through hole. This allows the buffer 12 to be disassembled, so that a new buffer 12 can be replaced if it is damaged.

[0046] The outer wall of the hollow enclosure panel 4 has placement slots 41 that communicate with and are perpendicular to the rectangular through holes, such as... Figure 7 As shown, the handle 123 is rotated 90° around the end of the plug post 122 and then placed in the placement slot 41. This avoids the handle 123 from rotating arbitrarily at the end of the plug post 122 without human intervention, which could cause the handle 123 to accidentally detach from the rectangular through hole and cause the buffer 12 to detach from the side wall of the hollow panel 4, thus affecting the stability of the buffer 12 against the outer wall of the automotive parts to buffer the impact force.

[0047] Example 2

[0048] Further improvements were made based on Example 1:

[0049] like Figure 1 As shown, several insertion holes 2 are provided on the upper cover 1, and several protrusions 9 are fixed on the bottom end face of the lower cover 8. When two adjacent boxes are stacked vertically, the lower cover 8 of the upper box is placed on the upper end face of the upper cover 1 of the lower box, and the protrusions 9 are inserted into the insertion holes 2. This allows the boxes containing automotive parts to be stacked together without tipping over, which is beneficial for batch turnover of boxes and improves turnover efficiency.

[0050] Car batteries provide electricity to automobiles and are essential components with flammable and explosive properties. Therefore, when a battery is compressed during handling, the internal separator is subjected to significant pressure from the electrolyte-soaked positive and negative electrodes, generating heat. As the deformation increases, the heat released inside the battery accumulates, causing a temperature rise. If the temperature exceeds the separator's safe operating temperature, the separator will thermally shrink, causing a large-scale short circuit inside the battery, leading to thermal runaway and even an explosion. When the car battery is placed in a housing, a buffer 12 is used to press against the outer wall of the battery, utilizing the elastic cushioning properties of the hollow rubber airbag to buffer the impact forces during battery handling, thus protecting the battery.

[0051] Hollow rubber airbags are divided into several independent spaces using thermo-pressing technology, such as... Figure 6As shown, during the hot pressing process, the space inside the hollow rubber airbag is divided into several independent spaces. At the same time, the pressure in each independent space will increase significantly compared to before. Each independent space of the hollow rubber airbag is a vacuum, and the independent space is filled with dry powder 121. When the hollow rubber airbag burns, the vacuum independent space under high pressure vacuum environment leaks and bursts instantly, causing the dry powder 121 to explode and splash onto the outside of the burning battery for fire extinguishing.

[0052] Example 3

[0053] Further improvements were made based on Example 2:

[0054] like Figure 2 , Figure 4 , Figure 5 As shown, the hollow panel 4 is divided into four equal parts. A snap-fit ​​seat 5 with a 90-degree angle between its upper end face edge and the L-shaped support block 7 is fixed to the bottom plate 6. A hinge notch is provided on the side of the snap-fit ​​seat 5 at the edge of the bottom plate 6. A hinge block 11 is hinged within the hinge notch, and the hinge block 11 is fixedly connected to the corresponding side wall of the hollow panel 4. Two side walls of the hollow panel 4 can be rotated around the hinge notch of the bottom plate 6 using the hinge block 11. The side wall of the snap-fit ​​seat 5 has a C-shaped snap-fit ​​notch, and a snap-fit... There is a snap-fit ​​shaft 10, and a rotating sleeve is rotatably sleeved at the middle position of the snap-fit ​​shaft 10 through an annular groove. The outer wall of the rotating sleeve is fixed with a connecting block that is fixedly connected to the side wall of the corresponding hollow enclosure 4. After the snap-fit ​​shaft 10 is snapped with the C-shaped snap-fit ​​notch of the corresponding snap-fit ​​seat 5, it can restrict the two side wall positions of the hollow enclosure 4 hinged, that is, in a vertical state. Together with the other two side walls of the hollow enclosure 4 that are fixedly connected to the outer wall of the corresponding L-shaped support block 7, they form a hollow enclosure 4, which plays a protective role for the automotive parts placed on the base plate 6.

[0055] The purpose of allowing two side walls of the hollow panel 4 to be flipped around the hinge position is to flip the two side walls to a horizontal state when placing automotive parts. After the automotive parts are placed on the base plate 6, the two side walls are flipped to a vertical state around the hinge position and then secured in the C-shaped notch of the corresponding snap-fit ​​seat 5 using the snap-fit ​​shaft 10, ensuring that the hollow panel 4 can act as a protective component to safeguard the automotive parts.

[0056] like Figures 8-10As shown, the hollow fence 4 side wall opposite to the buffer 12 is provided with an adjusting hole, and the adjusting hole is provided with an adjusting plate 42 for adjusting the position horizontally, a rectangular through hole is arranged on the adjusting plate 42, and the inserting column 122 of the buffer 12 is inserted into the rectangular through hole, and the rotating handle 123 is inserted into the rectangular through hole, and then the rotating handle 123 is rotated around the inserting column 122 as the rotating center until the rotating handle 123 is distributed in a staggered manner with the rectangular through hole. By arranging in this way, the buffer 12 can be detachably arranged on the side wall of the adjusting plate 42 with adjustable position, the position of the adjusting plate 42 is adjusted, and the side wall of the buffer 12 is ensured to abut against the outer wall of the automobile parts of different sizes. The same specification box can meet the storage of automobile parts of different sizes, so as to facilitate the turnover operation.

[0057] The two side walls inside the adjusting hole are hingedly connected with a pull plate 43 through a hinge hole, the two side walls of the adjusting plate 42 are provided with a rectangular adjusting hole, the upper and lower side walls inside the rectangular adjusting hole are provided with a limiting groove, the end of the pull plate 43 extends into the rectangular adjusting hole, and the upper and lower side walls of the end of the pull plate 43 are rotatably provided with a pin shaft 45 which is slidably connected with the limiting groove. One end of the pull plate 43 rotates around the hinge hole of the adjusting hole, and the other end slides along the limiting groove of the rectangular adjusting hole through the pin shaft 45, so as to adjust the position of the adjusting plate 42 to the side close to or away from the automobile parts, that is, to adjust the position of the buffer 12, until the side wall of the buffer 12 abuts against the automobile parts, and the adjusting operation of the adjusting plate 42 can be stopped.

[0058] When the position of the adjusting plate 42 changes, the pin shaft 45 will slide synchronously along the limiting groove, so as to compensate for the position difference when the position of the adjusting plate 42 is adjusted. In order to avoid the relative sliding adjustment between the adjusting plate 42 and the pin shaft 45 after the position of the adjusting plate 42 is adjusted, an elastic steel sheet 44 with a corrugated structure is arranged in the limiting groove. The side wall of the bending part of the elastic steel sheet 44 is slidably attached to the two side walls inside the limiting groove, and the end of the pin shaft 45 is inserted into the corrugated bending part of the elastic steel sheet 44. Figures 9-10 As shown, when the pin shaft 45 moves along the limiting groove, it will abut against the side wall of the bending part of the elastic steel sheet 44. With the continuous movement of the pin shaft 45, the bending part can be flattened and then enter the next bending part. The state of the elastic steel sheet 44 in this process is stretching, and then it is contracted to a corrugated structure. The above process is repeated until the pin shaft 45 moves to the required position, that is, the position of the adjusting plate 42 is adjusted. Under the condition that there is no external intervention, the pin shaft 45 will not flatten the corrugated structure of the elastic steel sheet 44 at will.

[0059] The pin shaft 45 can move to push the bending place flat and enter the next bending place. The elastic steel sheet 44 is in a state of stretching in this process and then shrinks to a corrugated structure. Therefore, one end of the elastic steel sheet 44 is fixedly connected with the inner side wall of the limiting groove, and the other end is provided with a buffer gap between the other end side wall in the limiting groove. In this way, the stretched elastic steel sheet 44 can be placed by the buffer gap, and the elastic steel sheet 44 can also be prevented from being pushed by the pin shaft 45 to move in the limiting groove.

[0060] While embodiments of the present application have been shown and described, it is to be understood that the embodiments described are merely divergences of the principles and spirit of the present application and that numerous modifications, changes, substitutions, and alterations can be made thereto without departing from the spirit and scope of the present application as defined by the appended claims and their equivalents.
