Description

Technical Field

[0001] This invention relates to the technical field of engine storage and transportation protection, and in particular to an impact-resistant engine packaging box. Background Technology

[0002] Engine packaging boxes are specialized industrial packaging containers used for the storage, handling, and transportation of engine products. Their main function is to provide physical protection for high-value, structurally precise engine assemblies, resisting risks such as drops, collisions, vibrations, stacking, and environmental corrosion that may be encountered in complex logistics processes, ensuring that the engines arrive at their destination in good condition and ready for immediate use.

[0003] In related technologies, engine packaging boxes typically employ an external protection and internal cushioning structure. The exterior is usually a rigid box made of wood, metal, or engineering plastics, while the interior is filled with polymer foam materials such as polyethylene and polyurethane. These materials are molded or cut into cushioning pads that match the engine's contours to secure the engine and absorb impact energy. To monitor abnormal impacts during transportation, existing solutions often attach mechanical or electronic impact indicator labels to the exterior of the packaging box.

[0004] However, external impact indicators are easily damaged or detached due to scratches or collisions during circulation, and since they are exposed outside the box, they are at risk of being maliciously tampered with or replaced, resulting in unreliable monitoring results. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this invention is to provide an impact-resistant engine packaging box, in which an indicator component is built-in and installed between the outer protective plate and the rigid inner frame, allowing it to directly sense the impact force transmitted by the box structure. This solves the problems of external indicators being easily damaged, detached, and potentially tampered with, improving the reliability and accuracy of impact monitoring, and providing a more precise and reliable status indication for engine transportation safety.

[0007] To achieve the above objectives, the present invention provides an impact-resistant engine packaging box, comprising:

[0008] The base plate is used to support the engine;

[0009] A rigid inner frame is fixedly mounted on the base plate to support and limit the engine. At least one slot is provided on the side wall of the rigid inner frame.

[0010] The outer protective plate is fixed to the rigid inner frame to withstand external impacts;

[0011] The indicator component is detachably inserted into the slot, and its sensing end face contacts the inner wall of the outer protective plate; when the impact force on the outer protective plate exceeds a preset threshold, the impact force is transmitted through contact to trigger the indicator component to produce an irreversible change.

[0012] In addition, the impact-resistant engine packaging box proposed according to the present invention may also have the following additional technical features:

[0013] Specifically, the indicator components include:

[0014] A housing whose shape matches the slot;

[0015] A trigger chamber is disposed within the housing;

[0016] The display chamber is arranged side-by-side with the trigger chamber within the housing;

[0017] A barrier is disposed between the trigger chamber and the display chamber.

[0018] Specifically, the trigger chamber is filled with a first substance, and the display chamber is filled with a second substance.

[0019] Specifically, the first substance is a liquid dye, and the second substance is an absorbent solid.

[0020] Specifically, the outer protective plate is provided with an observation window at the position corresponding to the housing.

[0021] Specifically, there are multiple slots and indicator components, distributed on different side walls and at different heights of the rigid inner frame.

[0022] Specifically, the bottom part of the base plate has at least two parallel support grooves, and the support grooves are provided with mounting parts.

[0023] Specifically, the mounting part is a mounting block formed by a C-shaped groove opened in the support groove.

[0024] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0025] 1. The present invention provides an impact-resistant engine packaging box, which detachably inserts an indicator component into a slot in a rigid inner frame, with its sensing end face directly abutting the inner wall of the outer protective plate. This allows the impact force to be transmitted through contact and trigger an irreversible change. Combined with the observation window correspondingly provided on the outer protective plate, the operator can directly observe the impact state from the outside without opening the box. This solves the problems of traditional external indicators being easily damaged, detached, or tampered with, and improves the reliability and authenticity of impact monitoring.

[0026] 2. The impact-resistant engine packaging box of the present invention provides a mounting part that is integrated with the support groove opened in the lower part of the base plate. This not only strengthens the overall structural rigidity of the base plate, but also provides a stable and convenient dedicated mounting point for the insertion of forklift forks or the connection of lifting ropes, thereby achieving safe and efficient handling of the packaging box and enhancing the bending resistance of the base plate.

[0038] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0039] The following description, in conjunction with the accompanying drawings, describes an impact-resistant engine packaging box according to an embodiment of the present invention.

[0040] like Figure 1 - Figure 9 As shown, an impact-resistant engine packaging box according to an embodiment of the present invention includes:

[0041] Base plate 1, used to support the engine;

[0042] A rigid inner frame 2 is fixedly mounted on the base plate 1 to support and limit the engine. At least one slot 21 is provided on the side wall of the rigid inner frame 2.

[0043] The outer protective plate 3 is fixed to the rigid inner frame 2 to withstand external impacts;

[0044] The indicator component 4 is detachably inserted into the slot 21, and its sensing end face is in contact with the inner wall of the outer protective plate 3. When the impact force on the outer protective plate 3 exceeds a preset threshold, the impact force is transmitted through contact to trigger the indicator component 4 to produce an irreversible change.

[0045] It should be noted that the base plate 1 is the basic load-bearing part of the packaging box. Its upper surface is used to directly place or indirectly support the engine through cushioning materials, and the lower part has reinforcing ribs to enhance the overall rigidity.

[0046] The rigid inner frame 2 serves as a cushioning and positioning component for the packaging box, and is preferably made of high-density molded foam. Its inner shape precisely matches the outer contour of the engine to wrap and secure the engine, preventing it from shifting during transportation. The slot 21 is a pre-drilled hole on its side wall.

[0047] The outer protective plate 3 is the outermost layer of protection and is preferably made of composite material. The outer protective plate 3 covers the outside of the rigid inner frame 2, isolates the rigid inner frame 2 from the external environment, and withstands external impact loads from handling, stacking, or accidental collisions.

[0048] The indicator component 4 faces the outside of the housing and, after installation, directly abuts against the inner wall of the outer protective plate 3, thereby establishing a force transmission path.

[0049] Specifically, when the packaging box is subjected to external impact, the impact energy first acts on the outer protective plate 3, causing it to deform or vibrate inward. Since the sensing end face of the indicating component 4 is in direct contact with the inner wall of the outer protective plate 3, the impact force is directly transmitted to the indicating component 4. When the transmitted impact force exceeds the preset trigger threshold inside the indicating component 4, it will drive an irreversible state change. Throughout the process, the rigid inner frame 2 absorbs most of the impact energy to protect the engine, while the slot 21 on its side wall provides an installation position for the indicating component 4, ensuring the reliability of the sensing transmission path. The base plate 1 provides a stable mounting foundation for all structures.

[0050] In one embodiment of the present invention, such as Figure 7 As shown, the indicator component 4 includes:

[0051] The housing 41 is shaped to match the slot 21;

[0052] The trigger chamber 42 is disposed inside the housing 41;

[0053] Display chamber 43 is arranged side by side with trigger chamber 42 within housing 41;

[0054] The barrier 44 is disposed between the trigger chamber 42 and the display chamber 43.

[0055] It should be noted that the housing 41 is a mounting base, and its outer contour mates with the slot 21 on the rigid inner frame 2 to ensure a stable installation and effective pressure transmission. The housing 41 is preferably made of plastic injection molding, which has sufficient strength to protect the internal cavity.

[0056] The trigger chamber 42 is the direct sensing part of the impact. When the chamber wall of the trigger chamber 42 is squeezed by an external force exceeding the threshold transmitted from the outer protective plate 3, it will deform and thus exert pressure on the internal material.

[0057] Display chamber 43 is the visual feedback unit for impact. Display chamber 43 is located on the easily observable side of housing 41, and its walls are partially transparent.

[0058] The barrier 44 is preferably made of a fragile and easily broken material and is fixed between the two chambers in a sealed manner. Under normal conditions, the barrier 44 isolates the two substances; when the pressure on the trigger chamber 42 exceeds the design value, the barrier 44 ruptures.

[0059] In this embodiment, the trigger chamber 42 is filled with a first substance, and the display chamber 43 is filled with a second substance.

[0060] In this embodiment, the first substance is a liquid dye and the second substance is an absorbent solid.

[0061] It should be noted that the first substance is a liquid with good fluidity, preferably a dyed liquid, whose main function is to flow under pressure and trigger a visible reaction after mixing.

[0062] The second substance is a solid material capable of reacting with the first substance to produce a color change, preferably a porous solid with strong adsorption properties. Its main function is to receive the flowing first substance and provide clear, permanent visual evidence through a dramatic color change.

[0063] In this embodiment, the outer protective plate 3 is provided with an observation window 5 at the location corresponding to the housing 41.

[0064] It should be noted that the observation window 5 is a transparent viewing area opened on the outer protective plate 3, and its position corresponds to the housing 41 of the indicator component 4. Its function is to allow the operator to observe the color change of the substance in the display chamber 43 of the indicator component 4 directly from the outside of the box without opening the packaging box and the outer protective plate 3, so as to determine whether an excessive impact has occurred during transportation.

[0065] In one embodiment of the present invention, such as Figure 7 As shown, there are multiple slots 21 and indicator components 4, distributed on different side walls and at different heights of the rigid inner frame 2.

[0066] It should be noted that the multiple slots 21 and the indicator component 4 can detect the impact from multiple directions. The operator can check each point one by one through the observation window 5 corresponding to each point, so as to make a more accurate assessment of the impact.

[0067] In one embodiment of the present invention, such as Figure 9 As shown, at least two parallel support grooves 11 are provided on the lower part of the base plate 1, and a mounting part 6 is provided in the support groove 11.

[0068] It should be noted that the groove structure is formed along the lower surface of the base plate 1, with two or more parallel grooves. These grooves serve as structural reinforcing ribs, enhancing the base plate 1's resistance to bending under long-distance loads and stresses. They also provide installation space for the mounting section 6.

[0069] The mounting part 6 is a component formed in the support groove 11 and is used to connect with the hoisting rope.

[0070] In one embodiment of the present invention, such as Figure 9 As shown, the mounting part 6 is a mounting block formed by a C-shaped groove opened in the support groove 11.

[0071] It should be noted that the C-shaped groove refers to the groove structure formed directly on the inner bottom surface of the support groove 11.

[0072] The mounting block and the base plate 1 are integrally formed to provide mounting points for external hoisting ropes.

[0073] When using this device, first place the engine inside the rigid inner frame 2 to securely enclose and limit its position. Then, fix the rigid inner frame 2 to the base plate 1, and insert one or more indicator components 4 into the corresponding slots 21 on the side wall of the rigid inner frame 2, ensuring that their sensing end faces are in close contact with the inner wall of the outer protective plate 3.

[0074] Next, the outer protective plate 3 is wrapped around and fixed to the outside of the rigid inner frame 2, at which point the observation window 5 is directly facing the display chamber 43 of the indicator component 4.

[0075] If the impact force on the outer protective plate 3 exceeds the preset threshold during transportation or storage, the impact force will be transmitted to the trigger chamber 42 through direct contact, causing the barrier 44 to break, allowing the first substance to rush into the display chamber 43 and be absorbed and colored by the second substance, resulting in an irreversible color change.

[0076] Operators can directly determine whether an over-limit impact event has occurred and its approximate location through observation window 5 without opening the box.

[0077] During handling, the forklift forks can be inserted into the C-shaped groove of the mounting section 6 along the direction of the support groove 11, or the lifting rope can be connected through the structure on the mounting section 6 to achieve safe and convenient handling.

[0078] In summary, the impact-resistant engine packaging box of this invention, by detachably inserting the indicator component into the slot of the rigid inner frame and having its sensing end face directly abut against the inner wall of the outer protective plate, allows the impact force to be transmitted through contact and trigger an irreversible change. Combined with the observation window correspondingly provided on the outer protective plate, operators can directly observe the impact state from the outside without opening the box. This solves the problems of traditional external indicators being easily damaged, detached, or tampered with, improving the reliability and accuracy of impact monitoring. Furthermore, by setting a mounting part integrated into the support groove in the lower part of the base plate, the overall structural rigidity of the base plate is strengthened, while providing a stable and convenient dedicated mounting point for inserting forklift forks or connecting lifting ropes. This achieves safe and efficient handling of the packaging box and enhances the bending resistance of the base plate.

[0079] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
