[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-4 This utility model provides a technical solution: a new energy vehicle hinge packaging box, comprising:
[0029] Box 1, and lifting mechanism 3 installed inside box 1;
[0030] The upper surface of the box 1 has a splicing groove 11, and the bottom of the splicing groove 11 has multiple sets of rotating shaft placement slots 12 for storing rotating shafts. The multiple sets of rotating shaft placement slots 12 are arranged in a rectangular array, and the bottom of each set of rotating shaft placement slots 12 is connected to an adjustment slot 14 for installing a lifting mechanism 3. A cavity 13 is provided inside the box 1. The bottom of each rotating shaft placement slot 12 is connected to the adjustment slot 14, forming an independent storage unit. The rotating shaft is vertically inserted into the rotating shaft placement slot 12, and the lifting mechanism 3 in the bottom adjustment slot 14 achieves precise positioning of the rotating shaft. The matrix arrangement of the rotating shaft placement slots 12 can achieve high-density storage, increasing the space utilization rate by more than 40%. The space utilization rate of traditional foam box 1 is only 50%-60%, while this technical solution improves the space utilization rate by 20%-30% through reasonable structural design.
[0031] Box 1 uses a material with a density of 45±5 kg / m³ 3 The closed-cell EPP (expanded polypropylene) material possesses excellent energy absorption characteristics, capable of absorbing over 95% of impact energy, providing comprehensive protection for high-precision rotating shafts. Simultaneously, EPP material exhibits outstanding resilience, recovering over 98% of its original shape after being compressed, ensuring stable performance over long-term use. Compared to traditional EPS materials, EPP material can be reused more than 5 times, significantly reducing long-term operating costs while also addressing environmental concerns.
[0032] Box 1 features a double-walled reinforced design, with staggered reinforcing ribs between the inner and outer walls. The wall thickness is 10mm, and the reinforcing ribs are 4mm thick. This structure maintains a lightweight design while enabling box 1 to withstand a maximum stacking pressure of 1500N, meeting the stacking requirements of up to 8 layers in logistics transportation. The inner wall of the pivot placement slot 12 adopts a micro-elastic design with a surface hardness of Shore A 55±5 degrees, forming a moderate compression fit with the pivot to prevent loosening or collision during transportation.
[0033] The lifting mechanism 3 includes an adjusting component 31 and a supporting component 32 installed in the adjusting groove 14;
[0034] The support member 32 includes a support plate 321 that supports multiple sets of rotating shafts, and a top plate 322 is fixedly connected to the lower surface of the support plate 321.
[0035] The support plate 321 adopts a honeycomb reinforced structure with a center thickness of 10mm and an edge thickness of 8mm. This variable thickness design ensures that the lifting force is evenly distributed at the bottom of the shaft. The surface of the support plate 321 undergoes electrostatic elimination treatment, with the surface resistivity controlled at 10^6-10^9Ω, effectively preventing damage to the electronic components of the shaft caused by static electricity accumulation. The contact surface between the support plate 321 and the shaft is designed with micro-vibration damping pads, 2mm thick, with a Shore A hardness of 40±5 degrees, further optimizing the protection of the shaft.
[0036] The adjusting component 31 includes a screw 311 rotatably mounted on one side of the adjusting groove 14. One end of the screw 311 is threadedly connected to a threaded sleeve 313, and one end of the threaded sleeve 313 is fixedly connected to a push plate 314 that abuts against the top plate 322. The support plate 321 supports the weight of the rotating shaft through the top plate 322. The push plate 314 moves along the inclined plane under the drive of the screw 311, converting the vertical displacement into a horizontal lifting force, so as to push the rotating shaft out of the rotating shaft placement groove 12, making it easier to remove the rotating shaft. At the same time, it can make the rotating shaft press against the cover plate 2, improving the stability of the rotating shaft storage.
[0037] The screw 311 is made of high-strength engineering nylon material, which is lightweight, high-strength, and corrosion-resistant. The screw 311 has a precisely designed pitch of 2mm, achieving a height adjustment accuracy of 0.5mm, and a lifting distance of 2mm per revolution. The screw 311's thread uses a trapezoidal thread design with a thread angle of 30°, reducing friction and lowering the operating torque by 30%, thus improving operating comfort.
[0038] The push plate 314 and the top plate 322 both have a right-angled trapezoidal cross-section. The inclined surfaces of the push plate 314 and the top plate 322 abut against each other, and the thickness of the top plate 322 is the same as that of the push plate 314. The angle of the inclined surfaces is precisely designed to be 30°±2°. This angle is an ideal angle optimized through mechanical analysis, ensuring sufficient force transmission efficiency while avoiding self-locking due to an excessively small angle. The height of the top plate 322 can be adjusted by moving the push plate 314, facilitating the clamping of the rotating shaft between the support plate 321 and the cover plate 2. Furthermore, when the cover plate 2 is not in use, it is easy to push the rotating shaft out and remove it.
[0039] The other end of the screw 311 passes through the box body 1 and is fixedly connected to a knob 312. A hidden hole 17 for mounting the knob 312 is provided on one side of the box body 1. Traditionally, manual handling requires the use of special tools. Using the knob 312, the screw 311 can be rotated quickly, thereby allowing the support plate 321 to quickly lift multiple sets of rotating shafts, improving the efficiency of handling the rotating shafts. The knob 312 is designed with an ergonomic grip with a diameter of 40mm and a non-slip texture on the surface, improving operating comfort. The knob 312 has a built-in torsion spring structure, which automatically returns to the hidden position when not in use, retracting into the hidden hole 17, without affecting the stacking and transportation of the packaging box. The periphery of the hidden hole 17 is provided with a buffer lip, forming a sealed fit with the knob 312 to prevent dust and moisture from entering.
[0040] Two sets of first telescopic sleeve rods 315 are fixedly connected to one side of the push plate 314. One end of each set of first telescopic sleeve rods 315 is fixedly connected to one side of the adjusting groove 14. Multiple sets of second telescopic sleeve rods 323 are fixedly connected to the lower surface of the support plate 321. The lower ends of the multiple sets of second telescopic sleeve rods 323 are fixedly connected to the bottom of the adjusting groove 14. The first telescopic sleeve rods 315 and the second telescopic sleeve rods 323 respectively restrict the movement trajectory of the push plate 314 and the support plate 321, ensuring the stability of the lifting and lowering movement.
[0041] Both the first telescopic sleeve 315 and the second telescopic sleeve 323 adopt a double-sealed design, filled with special drag-reducing grease, which reduces the coefficient of friction by 40% and makes operation smoother. The telescopic stroke of the second telescopic sleeve 323 is precisely controlled at 30mm. This value is determined based on the diameter of the rotating shaft and the optimized structure of the housing, ensuring that the rotating shaft can be completely stored in the rotating shaft placement slot 12, and can also be fully pushed out for easy removal when needed.
[0042] A cover plate 2 is snapped into the splicing groove 11. A splicing base plate 4, which mates with the splicing groove 11, is fixedly connected to the lower surface of the box body 1. The cross-section of the splicing base plate 4 is rectangular. The splicing base plate 4 and the box body 1 are connected by a plug-in joint, which improves the efficiency of assembly and disassembly. The splicing base plate 4 is made of the same material as the box body 1, namely EPP material, forming a consistent protective system.
[0043] The edge of the cover plate 2 has a downward-extending double-lip sealing edge, forming a double sealing structure with the inner wall of the splicing groove 11, achieving an IP54 protection level and effectively preventing dust and splash water from affecting the rotating shaft. A first locking groove 21 is formed on the upper surface of the cover plate 2, and a second locking groove 23 is formed on one side of the cover plate 2. A locking block 22 is fixedly connected to one end of each side of the cover plate 2 adjacent to the second locking groove 23. The inner wall of the first locking groove 21 has a miniature exhaust valve structure, including an embedded one-way breathable membrane and a supporting frame, with a breathability of 1000ml / m³. 2 •s, with a water permeability pressure greater than 50kPa, achieves internal and external pressure balance while maintaining waterproof performance, avoiding sealing problems caused by air pressure differences.
[0044] The cover plate 2 achieves a seal through the interference fit between the locking block 22 and the first locking groove 15, and at the same time, the cover plate 2 fits into the second locking groove 16, improving the stability of the installation. The surface of the locking block 22 is designed with a micro-elastic material layer with a thickness of 1.5mm. When the locking block 22 is inserted into the first locking groove 15, the micro-elastic layer will undergo moderate deformation to form a tight fit and improve the sealing effect.
[0045] Each end of the splicing groove 11 has a first slot 15 for installing the locking block 22, and the side of the splicing groove 11 adjacent to the first slot 15 has a second slot 16 for inserting the cover plate 2. The first slot 15 and the second slot 16 improve the efficiency of disassembling and assembling the cover plate 2. The entrance of the second slot 16 is designed with a guide slope at an angle of 15° to facilitate the precise positioning and quick insertion of the cover plate 2.
[0046] Each of the four corners of the upper surface of box 1 has a positioning protrusion with a height of 4mm. Correspondingly, the four corners of the splicing base plate 4 have grooves that mate with the positioning protrusions, used for anti-slip positioning when multiple boxes are stacked. The outer surface of box 1 features a honeycomb anti-slip texture to increase the coefficient of friction and prevent slippage during transportation. The central area of the splicing base plate 4 has an information marking area, including a recessed barcode area and an RFID tag mounting slot. The mounting slot is 2.5mm deep and 28mm in diameter, matching the size of standard logistics RFID tags, facilitating logistics tracking and inventory management.
[0047] In use, the shaft is placed in the shaft placement slot 12, and the cover plate 2 is embedded in the first slot 15 via the locking block 22. The cover plate 2 is then pushed through the first locking groove 21, causing it to insert into the second slot 16, thus improving the protection of the shaft and preventing moisture from entering the shaft placement slot 12. The double-lip sealing edge and the splicing groove 11 form a double sealing structure, ensuring an IP54 protection rating and effectively preventing the influence of environmental moisture and dust on the shaft. Simultaneously, the miniature exhaust valve structure allows for pressure balance inside and outside the packaging, avoiding sealing problems caused by climate changes or altitude variations.
[0048] Rotating knob 312 drives screw 311 to rotate, adjusting the position of screw sleeve 313. This allows the inclined surface of push plate 314 to contact the inclined surface of top plate 322, facilitating the adjustment of support plate 321's position and ensuring the shaft abuts against cover plate 2, thus improving shaft installation stability. The 30° optimized inclined surface design reduces operating torque by 30% compared to traditional designs, making operation easier. The precise 2mm pitch design ensures accurate 2mm height adjustment per revolution, achieving precise control of shaft support.
[0049] When the shaft needs to be removed, turn knob 312 in the opposite direction to disengage the shaft from cover plate 2, then remove cover plate 2. Repeat turning knob 312 to push the shaft out of shaft placement slot 12 using support plate 321, thus facilitating the removal of the shaft and improving the efficiency of shaft removal. The honeycomb reinforced structure and thickened design of support plate 321 ensure that the lifting force is evenly distributed at the bottom of the shaft, preventing the shaft from tilting or getting stuck during the removal process.
[0050] During transportation and storage, multiple boxes can be precisely positioned using the positioning protrusions on the upper surface and the grooves on the bottom splicing plate 4, forming a stable stacking structure. Up to eight layers can be stacked, withstanding a stacking pressure of 1500N. The honeycomb anti-slip texture increases the coefficient of friction between the boxes, further enhancing stacking stability. The RFID tag mounting slots and barcode area on the splicing plate 4 facilitate packaging tracking and management by the logistics system, improving supply chain efficiency.
[0051] The EPP material used in the packaging box has a density of 45±5 kg / m³. 3 Compared to traditional packaging, it reduces weight by more than 40%, significantly lowering transportation costs. The closed-cell rate of EPP material exceeds 98%, effectively preventing moisture penetration and protecting the shaft from humid environments during long-term storage. Furthermore, EPP material maintains stable performance over a wide temperature range of -40℃ to +120℃, adapting to transportation needs in various global climates.
[0052] When the packaging box needs to be transported empty, its lightweight design reduces the weight of the empty packaging by more than 40% compared to traditional packaging, significantly lowering return air freight costs. Furthermore, EPP material can be reused more than five times more times than traditional EPS material, significantly extending the lifespan of the packaging box and reducing long-term usage costs.
