Description

Technical Field

[0001] This invention relates to the field of pallet box technology, specifically a safety pallet box for transporting automotive parts. Background Technology

[0002] Currently, automotive parts transportation packaging is mainly divided into three categories: wooden crates, metal fixed frames, and traditional collapsible crates. Among them, collapsible crates are gradually becoming the mainstream choice due to their "foldable storage, high reusability, and small space occupation." During non-transportation periods, the collapsible panels can be folded, and the storage volume is only one-third to one-fifth of the unfolded state, significantly reducing warehousing and return transportation costs.

[0003] While existing traditional collapsible boxes can meet basic transportation needs, they have significant shortcomings in terms of "adaptability, intelligent protection, and ease of operation." Especially in scenarios involving mixed loading of multiple parts and transportation under complex road conditions, they are unable to fully meet the refined requirements of automotive logistics, which can easily lead to parts damage and low logistics efficiency. There is an urgent need to improve their overall performance through structural innovation. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This pallet box features a dual-adjustment design with a folding mechanism, allowing it to flexibly adapt to automotive parts of different sizes and shapes, such as cylinder blocks and gearbox housings. It eliminates the need for custom-made packaging, effectively solving the size limitations of traditional wooden crates. Operators only need to adjust the angle of the sliding plate and the extension length of the insert plate to ensure the pallet fits tightly against the sides and top protrusions of the parts, reducing collision gaps during transport and significantly lowering the rate of damage from impacts. Simultaneously, it eliminates the cost of custom-made packaging, improving packaging versatility and economy.

[0017] 2. The protective mechanism can automatically switch protection modes according to the folded or unfolded state of the enclosure, without manual intervention. When the enclosure deflects, the tower-shaped plate slides in conjunction with the spring rod, driving the telescopic rod to extend or retract via the magnetic block, providing precise limiting and force protection for the enclosure and preventing deformation caused by external pressure. The cooperation between the magnetic block and the magnetic shielding plate ensures accurate magnetic force action, preventing malfunction of the telescopic rod. The elastic element also buffers the impact of transportation bumps on the enclosure, comprehensively improving the overall structural stability of the enclosure box and providing reliable protection for the transportation of parts.

[0018] 3. The locking mechanism, with its self-locking design using equilateral triangular blocks, can quickly fix the cover plate in position, preventing it from loosening during transport. Furthermore, the locking mechanism is linked to the adjustment mechanism; when the cover plate is fixed, the observation window automatically unlocks, facilitating monitoring of the parts' status during transport without additional operation. Unlocking the cover plate simply requires pressing and rotating the rectangular plate, making operation labor-saving and allowing for single-person loading and unloading, significantly improving parts handling efficiency. It also simplifies the status monitoring process during transport, providing convenience for the entire automotive parts transportation process. Attached Figure Description

[0033] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 13 The present invention provides a technical solution: Example 1: Component loading and folding mechanism adaptation stage.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the enclosure box has a U-shaped enclosure 1 as its main frame, with a support bearing 21 welded to its outer side. Inside the support bearing 21, a rotating plate 22 is rotatably installed via a shaft. Inside the rotating plate 22, a sliding plate 23 is slidably fitted. At the end of the sliding plate 23 away from the rotating plate 22, a first bushing 24 is welded. Inside the first bushing 24, a central shaft 25 is rotatably installed. The upper and lower ends of the central shaft 25 are rotatably connected to a second bushing 26. The central shaft 25 is slidably fitted with the bottom groove of the inner cavity of the U-shaped enclosure 1, together forming a folding mechanism 2.

[0036] The operator first places the U-shaped enclosure 1 on the transport pallet and adjusts the folding mechanism 2 according to the size of the parts: manually rotate the rotating plate 22 inside the support shaft seat 21. The rotating plate 22 deflects around the shaft, causing the internal insert plate 23 to slide out. The insert plate 23 drives the central shaft 25 to slide along the bottom groove of the U-shaped enclosure 1 through the first bushing 24. The second bushing 26 connects with the insert plate 23 on the other side and slides out accordingly. Continuously adjust the angle and extension length of the rotating plate 22 and the insert plate 23 until the two side panels completely fit the sides and top protrusions of the parts, forming a "U-shaped body + two side fitting enclosures" wrapping structure to prevent the cylinder from swaying laterally or moving longitudinally during transportation.

[0037] The folding mechanism 2 can be adapted to different sizes and shapes of automotive parts such as cylinder blocks and gearbox housings through the dual adjustment of "rotating plate 22 + sliding plate 23". The side panel fits tightly with the surface of the parts, reducing the collision gap during transportation, reducing the damage rate of parts, and avoiding the size limitations of traditional wooden box packaging.

[0038] Example 2: Cover plate closing and protective mechanism activation stage.

[0039] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the protective mechanism 3 and the cover plate 4 work together to ensure safety protection when the enclosure is folded. The outer end face of the cover plate 4 is welded with a first rail 31, which is internally fitted with a first spring rod 32. The first spring rod 32 is composed of an elastic element and a rod. The bottom of the first spring rod 32 is sequentially fixed with a first magnetic block 33, a first magnetic shielding plate 34, and a second magnetic block 35. The bottom of the first rail 31 is welded with a first telescopic rod 36, which internally fixes a third magnetic block 37. The bottom of the cover plate 4 is welded with a second rail 30, which internally fits a second spring rod 301. The second spring rod 301 is fixed to the first spring rod 32 via a connecting bar 39. The bottom of the second rail 30 is fixed with a fourth magnetic block 302, a second magnetic shielding plate 303, and a fifth magnetic block 304. The bottom of the second rail 30 is welded with a second telescopic rod 305, which internally fixes a sixth magnetic block 306. The cover plate 4 is internally fitted with a tower-shaped plate 38, which is sleeved on the outside of the central shaft 25.

[0040] When the cover plate 4 is closed on top of the U-shaped enclosure 1, the central shaft 25 and the tower plate 38 are connected together. If the enclosure formed by the rotating plate 22 and the sliding plate 23 deflects inward and the central shaft 25 slides inward along the bottom groove, the tower plate 38 will move inward along with the central shaft 25, and its two sides will change from vertical planes to inclined planes to fit against the first elastic rod 32. The first elastic rod 32 extends outward along the first rail 31 under the action of the elastic element, and at the same time, it pulls the second elastic rod 301 to slide outward along the second rail 30 through the connecting bar 39. At this time, the first magnetic block 33 at the bottom of the first spring rod 32 moves to directly above the first telescopic rod 36, generating a repulsive force with the third magnetic block 37, pushing the first telescopic rod 36 downwards; the fourth magnetic block 302 at the bottom of the second spring rod 301 and the sixth magnetic block 306 generate an attractive force, pulling the second telescopic rod 305 to retract. Through the "extension and retraction of the telescopic rods," the folding panel is limited and protected against force, preventing the panel from being deformed by external pressure. If the panel is in the unfolded state, the magnetic blocks are triggered in the opposite direction, the outer first telescopic rod 36 retracts, and the inner second telescopic rod 305 extends, forming an external protective barrier.

[0041] The first magnetic shielding plate 34 and the second magnetic shielding plate 303 have the same function. When the first magnetic block 33 and the third magnetic block 37 generate a repulsive force, they isolate the magnetic force of the second magnetic block 35 to prevent it from affecting the former's repulsive force.

[0042] The protective mechanism 3, through the design of "tower-shaped plate 38 linkage + magnetic block driven telescopic rod", can automatically switch the protective mode according to the folding and unfolding state of the enclosure, without the need for manual adjustment; the cooperation between the magnetic block and the magnetic shielding plate ensures the precise application of magnetic force and avoids malfunction of the telescopic rod, while the elastic element provides cushioning, reduces the impact of transportation bumps on the enclosure, and improves the overall structural stability.

[0043] Example 3: Locking mechanism and adjustment mechanism linkage and fixing stage.

[0044] like Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the locking mechanism 5 and the adjusting mechanism 6 work together to achieve stable fixation of the cover plate 4 and control of the observation window 506. The outer plate 51 of the locking mechanism 5 is welded to the outer end face of the cover plate 4, and the inner sliding fits the rectangular plate 52. The top of the rectangular plate 52 is welded to the top rod 53, and the outer periphery of the top rod 53 is fitted with a first spring 54. The bottom of the rectangular plate 52 is welded to the bottom of the rectangular plate 52. The outer side of the U-shaped enclosure 1 is welded to the connecting plate 56, and the top is welded to the third rail 57 and the fourth rail 50. The third rail 57 contains an equilateral triangle block 58 and a second spring 59, and the fourth rail 50 contains an inverted triangle block 501 and a third spring 502. The top of the top rod 53 is connected to the extension rod 504 through the bearing 503, and the bottom of the extension rod 504 is welded to the teasing handle 505.

[0045] The cylindrical sleeve 61 of the adjustment mechanism 6 is welded to the outside of the U-shaped enclosure 1. The first cylinder 62 is slidably fitted inside. The first cylinder 62 is fitted to the stirring handle 505 through the connecting sleeve 63. The sliding head 64 is welded to the outside and slides along the arc groove of the cylindrical sleeve 61. The second cylinder 65 is welded to one end of the first cylinder 62, and the fourth spring 66 is fitted around its periphery. The observation window 506 is rotatably installed on the outside of the U-shaped enclosure 1 through the connecting shaft. After cover plate 4 is closed, the operator manually presses down the rectangular plate 52 inside the outer plate 51. The rectangular plate 52 moves the trapezoidal plate 55 downward, squeezing the equilateral triangle block 58 inside the third rail 57. The equilateral triangle block 58 compresses the second spring 59. When the trapezoidal plate 55 moves below the equilateral triangle block 58, the second spring 59 rebounds and pushes the equilateral triangle block 58 back to its original position. Its bottom plane forms a self-locking mechanism with the trapezoidal plate 55, fixing the position of cover plate 4. At the same time, the downward movement of the rectangular plate 52 moves the top rod 53, the extension rod 504, and the lever 505 downward in sync. The lever 505 squeezes the connecting sleeve 63, pushing the first cylinder 62 to deflect along the cylinder sleeve 61. The slider 64 slides along the arc groove, causing the second cylinder 65 to stretch the fourth spring 66 and move away from the observation window 506. At this time, the observation window 506 can be opened and closed freely, making it convenient to check the status of parts during transportation. When the cover plate 4 needs to be opened, press the rectangular plate 52 and the top rod 53 downwards and rotate them 90 degrees clockwise. The trapezoidal plate 55 and the inclined surface of the inverted triangle block 501 are pressed together, and the first spring 54 rebounds and pushes the rectangular plate 52 upwards to reset. The handle 505 presses the connecting sleeve 63 upwards, and the first cylinder 62 is reset under the action of the fourth spring 66. The second cylinder 65 relocks the observation window 506, and then the cover plate 4 can be lifted to take out the parts.

[0046] The self-locking design of the locking mechanism 5 with the equilateral triangle block 58 ensures that the cover plate 4 is firmly fixed and does not loosen during transportation. The adjustment mechanism 6 is linked with the locking mechanism 5 to realize the automatic unlocking and locking of the observation window 506 without additional operation, which improves the convenience during transportation. When unlocking, only the rectangular plate 52 needs to be rotated, which is labor-saving and can be completed by a single person, greatly improving loading and unloading efficiency.

[0047] The working principle of this invention is as follows: During the component loading stage, the shape of the enclosure is adjusted by the folding mechanism 2 to fit the component. The U-shaped enclosure 1 serves as the main frame. The rotating plate 22 inside the pivot seat 21 is rotated, and the rotating plate 22 drives the sliding plate 23 to slide out. The sliding plate 23 drives the central shaft 25 to move through the first bushing 24. The central shaft 25 slides along the bottom groove of the U-shaped enclosure 1. At the same time, the second bushing 26 at its upper and lower ends assists in the rotation, so that the enclosures on both sides can be folded or unfolded according to the size of the component until the enclosure fits the surface of the component, thus avoiding the component shaking and colliding during transportation.

[0048] When the cover plate 4 is closed, the protective mechanism 3 is activated simultaneously to achieve safety protection. The cover plate 4 covers the top of the enclosure, and the tower-shaped plate 38 on the outside of the central shaft 25 moves down with the cover plate 4. When the enclosure formed by the rotating plate 22 and the sliding plate 23 deflects inward, that is, when the central shaft 25 slides inward along the bottom groove of the U-shaped enclosure 1, the inclined surfaces on both sides of the tower-shaped plate 38 will be squeezed and matched with the first elastic rod 32. At the same time, under the action of the elastic element inside the first elastic rod 32, it will extend outward along the first rail 31. The first elastic rod 32 will move towards the center as the tower-shaped plate 38 moves inward. At the same time, the first elastic rod 32 drives the connecting bar 39 to pull the second elastic rod 301 to slide outward along the second rail 30. At this time, the first magnetic block 33 at the bottom of the first spring rod 32 will move to the top of the first telescopic rod 36 and generate a repulsive force with the third magnetic block 37 inside the first telescopic rod 36, causing the first telescopic rod 36 to extend downwards. Meanwhile, the second magnetic block 35, which was originally above the first telescopic rod 36, will be separated, and the magnetic force will be pressed to the minimum by the first magnetic shielding plate 34. Similarly, the fourth magnetic block 302 at the bottom of the second spring rod 301 will attract the sixth magnetic block 306 inside the second telescopic rod 305, causing the second telescopic rod 305 to retract. When the enclosure formed by the rotating plate 22 and the sliding plate 23 is in a vertical state, the first telescopic rod 36 on the outside retracts, and the second telescopic rod 305 on the inside extends downwards to limit and protect the two. However, when the enclosure is in a folded state, the first telescopic rod 36 on the outside extends downwards, and the second telescopic rod 305 on the inside retracts to provide external protection for the two.

[0049] The locking mechanism 5 and the adjusting mechanism 6 are linked to fix the cover plate 4. After the cover plate 4 is closed, the operator manually moves the rectangular plate 52 inside the outer plate 51 downwards, causing the trapezoidal plate 55 to press against the equilateral triangle block 58 inside the third rail 57. The equilateral triangle block 58 compresses the second spring 59 until the trapezoidal plate 55 moves below the equilateral triangle block 58. Under the elastic force of the second spring 59, the equilateral triangle block 58 returns to its original position, and the flat part at the bottom of the equilateral triangle block 58 forms a self-locking mechanism with the trapezoidal plate 55. At the same time, during the downward movement of the rectangular plate 52, the extension rod 50 connected to it via the bearing 503... 4 will move downwards in sync with the lever 505, and press down on the connecting sleeve 63 inside the adjustment mechanism 6. Then, the first cylinder 62 connected to the connecting sleeve 63 will deflect downwards in sync. The slider 64 fixed to the outside of the first cylinder 62 will slide to the right along the arc groove opened on the cylinder sleeve 61, driving the first cylinder 62 and the second cylinder 65 to move to the right in sync. The fourth spring 66 will stretch and deform. At this time, the second cylinder 65 will move away from the observation window 506, so that the observation window 506 can be closed and opened at will. In addition, when it is necessary to open the cover plate 4, press the rectangular plate 52 and the top rod 53 downwards first, and then rotate them 90 degrees clockwise or counterclockwise. At this time, the trapezoidal plate 55 will be squeezed and matched with the inclined end of the inverted triangle block 501. At the same time, under the action of the first spring 54, it will reset upwards. In addition, during the process of the trapezoidal plate 55 resetting upwards, the lifting handle 505 will squeeze the connecting sleeve 63 upwards, so that the first cylinder 62 will lock the observation window 506 again, and the cover plate 4 can be lifted.

Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
