Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a reusable packaging box. Background Technology

[0002] Currently, corrugated cardboard boxes are still used as outer packaging materials for products in the logistics and transportation process of the electrical appliance industry. These boxes are usually for single use, and are discarded or recycled at a low value after the transportation task is completed, resulting in serious resource waste. According to statistics, the overall recycling rate of packaging boxes in the electrical appliance industry is less than 50%, and the recycling rate is almost zero. The large amount of discarded packaging puts significant pressure on the environment.

[0003] Although there have been initial attempts at reusable packaging in some industries in recent years, existing reusable packaging boxes still have significant limitations. For example, patent application number 202122538708.0 discloses a foldable reusable packaging box made of PP hollow board material. Although it has a certain degree of reusability, its structural strength is limited, and the actual number of cycles is difficult to exceed 30, resulting in insufficient economic efficiency. Patent application number 202121676686.8 proposes a reusable packaging box with a top locking structure. Although it eliminates disposable tape and improves environmental protection, it does not integrate intelligent monitoring functions and cannot meet the modern logistics demand for full traceability. While patent application number 202421472952.9 introduces RFID tags into the packaging box and sets positioning blocks and anti-collision frames to protect the tags, its structure is complex and costly, and it lacks support for multiple sensing elements such as sensors, making it difficult to achieve real-time monitoring and recording of abnormal environmental factors such as temperature, humidity, vibration, and drops during transportation.

[0004] Overall, existing reusable packaging solutions generally suffer from problems such as short cycle life, low level of intelligence, limited functionality, and poor recycling management efficiency, resulting in a higher cost per use than traditional disposable cardboard boxes, making it difficult to achieve large-scale application in the electrical appliance industry. Utility Model Content

[0005] One objective of this invention is to solve or at least alleviate some or all of the aforementioned problems. Therefore, one objective of this invention is to provide a reusable packaging box to address the problems of existing packaging boxes having a low number of reusable cycles and limited functionality.

[0006] This utility model provides a reusable packaging box, including a box body, the box body including an upper cover plate, and an electronic component compartment provided on the upper cover plate;

[0007] The electronic component compartment includes a compartment body and a compartment cover fixed to the upper cover plate;

[0008] The compartment has a receiving cavity. One side of the compartment cover is rotatably connected to the compartment, and the other side is detachably snapped onto the compartment via a snap-fit ​​structure to close the opening of the receiving cavity.

[0009] The cavity is equipped with an electronic tag and / or an environmental sensor.

[0010] Optionally, the buckle structure includes a hook-type buckle structure, a sleeve-type buckle structure, or a ball-type buckle structure.

[0011] Optionally, the compartment cover is L-shaped and includes an extension arm that bends toward the compartment body;

[0012] The hook-type buckle structure includes a hook disposed on the extension arm and a groove disposed on the side wall of the compartment body and matching the hook;

[0013] The hook has an inclined guide surface for guiding engagement and a locking surface adjacent to the inclined guide surface;

[0014] When the compartment cover is engaged with the compartment body, the locking plane abuts against the inner wall of the slot to achieve engagement and fixation.

[0015] Optionally, the extension arm is further provided with an opening groove, and the opening groove is located on the surface of the extension arm opposite to the hook.

[0016] Optionally, the compartment cover is L-shaped and includes an extension arm that bends toward the compartment body;

[0017] The sleeve-type buckle structure includes a snap-fit ​​hole disposed on the extension arm and a snap-fit ​​post disposed on the compartment body and matching the snap-fit ​​hole;

[0018] With the compartment cover engaged with the compartment body, the engaging pin is inserted into the engaging hole to achieve engagement and fixation.

[0019] Optionally, the bottom of the extension arm has an inclined surface, and the angle between the inclined surface and the side wall of the extension arm on the side away from the compartment body is an acute angle.

[0020] Optionally, the spherical snap-fit ​​structure includes a spherical insertion part disposed on the compartment cover, and an insertion groove disposed on the compartment body and matching the spherical insertion part;

[0021] With the compartment cover engaged with the compartment body, the spherical insertion part is inserted into the insertion groove.

[0022] Optionally, the plate structure of the box body is a hollow polypropylene plate, and the hollow polypropylene plate is pressed with creases for folding.

[0023] Optionally, the housing further includes a bottom plate disposed opposite to the top cover plate, and a side plate connected between the top cover plate and the bottom plate;

[0024] The side plate is equipped with a folding hinge at the vertical edge pressure line.

[0025] Optionally, the housing further includes a bottom plate disposed opposite to the top cover plate, and a side plate connected between the top cover plate and the bottom plate;

[0026] The upper cover plate and the side plate, as well as the bottom plate and the side plate, are detachably locked together by a locking structure.

[0027] This utility model provides a reusable packaging box suitable for the electrical appliance industry. By rationally setting up an electronic component compartment on the box's top cover, RFID electronic tags and various environmental sensors (such as temperature and humidity sensors, force sensors, and acceleration sensors) are integrated and pre-embedded in the compartment's internal cavity. This enables intelligent sensing and data collection of the packaging box's identity information, logistics trajectory, and transportation environment status throughout the entire process. This design not only effectively prevents the intrusion of external dust and moisture but also maintains the stability and safety of electronic components under complex logistics conditions such as vibration and collision through a snap-fit ​​structure, significantly reducing the risk of monitoring failure due to component damage or data loss.

[0028] The electronic component compartment uses an openable cover and various snap-fit ​​structures (such as hook-type, sleeve-type, or ball-type snap-fits) to ensure sealing and impact resistance while greatly facilitating the rapid inspection, replacement, or upgrade of internal electronic tags or environmental sensors during the recycling, testing, and maintenance of the reusable packaging box. This supports the continuous intelligent operation of the packaging box throughout its entire life cycle.

[0029] Furthermore, by combining the PP hollow board material used in the box body with the hinge structure embedded in the vertical folding points, the overall box body achieves lightweight and foldable design while possessing excellent compression resistance, impact resistance, and fatigue resistance, supporting the packaging box to be reused more than 30 times. Through the synergistic improvement of intelligent monitoring and structural durability, this reusable packaging box has a significantly lower cost per use than traditional disposable cardboard boxes, effectively solving the problem of high overall cost caused by insufficient reuse count and limited functionality of existing reusable packaging boxes. It provides the electrical appliance industry with a reusable packaging system solution that combines green environmental protection and intelligent management.

[0030] Specifically, the aforementioned reusable packaging boxes can achieve the following technical effects:

[0031] 1. By pre-installing RFID tags, the identity information of the packaging box can be bound and the logistics can be tracked throughout the entire process. It can also be combined with various environmental sensors to collect real-time transportation environment data (such as temperature, humidity, impact intensity, tilt angle, etc.) to establish a complete logistics data archive and provide a reliable basis for abnormal event analysis.

[0032] 2. Made of PP hollow board material with a folding hinge structure, using recyclable green materials, abandoning disposable packaging, and strengthening the pressure resistance and fatigue resistance of the box edges, significantly increasing the number of times it can be reused to more than 30 times, making the cost of packaging per use lower than that of traditional cardboard boxes, and having good economic and environmental benefits.

[0033] 3. The electronic component compartment adopts a snap-lock design, which supports quick opening and closing and component replacement, facilitating system maintenance and functional expansion, and adapting to the intelligent packaging needs of different scenarios.

[0034] 4. By recording abnormal environmental factors during the logistics process through environmental sensors, data support can be provided for the analysis of the causes of packaging damage, thereby guiding the optimization design of packaging liner structure and materials, and improving the overall logistics protection performance.

[0049] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0050] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0051] Figure 1 This is a structural schematic diagram of a reusable packaging box provided in an embodiment of the present utility model. Figure 2 for Figure 1 Enlarged structural diagram at point A Figure 3 This is a schematic diagram of the structure of an electronic component compartment provided in an embodiment of the present invention. Figure 4 This is a partial cross-sectional structural diagram of an electronic component compartment provided for an embodiment of the present invention. (See diagram below.) Figures 1-4 As shown, the reusable packaging box provided in this embodiment of the present invention includes a box body 10, which includes an upper cover plate 101. An electronic component compartment 20 is disposed on the upper cover plate 101. The electronic component compartment 20 includes a compartment body 201 and a compartment cover 202 fixed to the upper cover plate 101. A receiving cavity (not shown in the figure) is formed inside the compartment body 201. One side of the compartment cover 202 is rotatably connected to the compartment body 201, and the other side is detachably engaged with the compartment body 201 through a snap-fit ​​structure 30 to close the opening of the receiving cavity. An electronic tag (not shown in the figure) and / or an environmental sensor (not shown in the figure) are disposed inside the receiving cavity.

[0052] Specifically, the housing 10 is made of high-strength recyclable material, which has good pressure resistance, moisture resistance and wear resistance.

[0053] The enclosure 10 includes an openable top cover 101, which is used to close the enclosure 10 and protect the internal electrical products.

[0054] The outer surface of the top cover 101 is provided with an electronic component compartment 20. The electronic component compartment 20 is used to accommodate and fix electronic components such as electronic tags and environmental sensors to protect the electronic components from damage caused by external dust, moisture and mechanical impact, and to ensure the stability and reliability of the electronic components during multiple cycles of use, which helps to increase the number of times the reusable packaging box can be used.

[0055] Placing the electronic component compartment 20 on the upper cover 101 can prevent the electronic components from being squeezed by the items inside the box during transportation. At the same time, this position is conducive to the stable transmission of wireless signals, reduces the shielding and interference of signals by metal objects or liquid goods, and improves the stability and reliability of data reading.

[0056] Furthermore, the compartment 201 of the electronic component compartment 20 is fixed to the upper cover plate 101. The compartment 201 and the upper cover plate 101 can be securely assembled by means of bonding, snap-fitting, screw connection or integral molding.

[0057] For example, the hopper body 201 and the top cover 101 are integrally molded structures with high structural strength, good waterproof and dustproof performance, and no additional assembly process is required, which helps to reduce production costs and improve product consistency.

[0058] Furthermore, one end of the cover 202 of the electronic component compartment 20 is rotatably connected to one side of the compartment body 201 to enable the cover 202 to be flipped open and closed.

[0059] In some embodiments, such as Figure 3 As shown, the rotatable connection methods include: when manufacturing the electronic component compartment, the compartment cover 202 and the compartment body 201 are made of a single piece of material (such as a PP hollow board), and a locally thinned connection area (i.e., a thin-walled connection section) is set at the connection between the two. This thin-walled connection section serves as a flexible pivot, allowing the compartment cover 202 to bend and flip around it; or, the compartment cover 202 and one side of the compartment body 201 are rotatably connected by a continuous pressure line pressed onto the PP hollow board. The pressure line serves as a rotation axis, allowing the compartment cover 202 to be folded and opened along it. The structure is simple and requires no additional connectors.

[0060] In some embodiments, the rotatable connection method includes: the cover 202 and one side of the body 201 are connected by a rotatable connection structure. The rotatable connection structure includes a micro hinge disposed between the two. The micro hinge includes a connecting ear disposed opposite to each other and a rotating shaft passing through the connecting ear. The two connecting ears are respectively fixed on the cover 202 and the body 201. The cover 202 achieves stable rotation through the rotating shaft. The connection is reliable and has high durability.

[0061] Furthermore, the interior of the compartment 201 has a receiving cavity, which is an open mouth body used to accommodate electronic components such as electronic tags and environmental sensors.

[0062] In some embodiments, the accommodating cavity is formed by the side wall and bottom wall of the compartment 201, and its shape is adapted to the electronic component to be installed, and its depth is adapted to the thickness of the electronic component, so as to achieve limiting and fixing and prevent the electronic component from being displaced or collided during transportation.

[0063] In some embodiments, the inner wall of the accommodating cavity is provided with a buffer pad or limiting ribs to provide buffer protection and circumferential limiting for electronic components, thereby improving shock resistance.

[0064] Furthermore, the electronic component compartment 20 is provided with a snap-fit ​​structure 30 on the side opposite to the rotatable connection position. The compartment cover 202 is detachably snapped onto the compartment body 201 through the snap-fit ​​structure 30 to realize the opening and sealing of the accommodating cavity.

[0065] When the cover 202 is engaged by the snap-fit ​​structure 30, the accommodating cavity forms a closed space, which can effectively prevent external dust, moisture and mechanical impact from damaging the internal electronic components, and helps to increase the number of times the reusable packaging box can be reused. At the same time, the detachable snap-fit ​​method allows the electronic component compartment 20 to be repeatedly opened and closed, which facilitates the inspection, replacement or upgrade of internal electronic components during the recycling, testing and maintenance of the reusable packaging box, and supports high-frequency recycling.

[0066] In some embodiments, the rotatable connection is located on the edge of the compartment 201 near the geometric center of the upper cover plate 10, so that the compartment cover 202 can be flipped open from the edge of the upper cover plate 10 toward the center of the upper cover plate 10, which is convenient to operate and is not easily affected by external force after opening.

[0067] In some embodiments, an electronic tag is provided inside the accommodating cavity. The electronic tag is used to store the unique identification information of the reusable packaging box and related information of the product it contains (such as box number, customer, number of cycles, etc.). It supports rapid reading and writing in a non-contact manner at various logistics nodes such as warehousing, transportation, sorting, and recycling, so as to realize automatic inbound and outbound, transit identification and path tracking.

[0068] The electronic tag can be fixed to the bottom or side wall of the accommodating cavity, or it can be detachably installed in the accommodating cavity through a slot, adhesive, or strap structure.

[0069] In some embodiments, the electronic tag is a radio frequency identification (RFID) tag, specifically an ultra-high frequency (UHF) RFID tag, which supports long-distance non-contact identification and data communication.

[0070] In some embodiments, an environmental sensor is provided inside the accommodating cavity. The environmental sensor is used to collect key environmental parameters during the transportation process in real time, including temperature, humidity, impact acceleration, tilt angle, etc., so as to record and warn of abnormal logistics events such as drops, inversions, and severe vibrations.

[0071] Optionally, environmental sensors include, but are not limited to, at least one of the following: temperature sensor (for monitoring the temperature of the transportation environment and preventing electrical components from being damaged by heat), humidity sensor (for preventing circuit corrosion caused by moisture), force sensor (for recording impact and drop events during transportation), acceleration sensor (for recording impact and drop events during transportation), and tilt sensor (for determining whether it is inverted or overturned).

[0072] The electronic component compartment 20 can be equipped with electronic tags or environmental sensors individually, or both electronic tags and environmental sensors can be installed simultaneously to adapt to different application scenarios.

[0073] In some embodiments, an electronic tag and at least one environmental sensor are installed within the accommodating cavity. Environmental data collected by the sensor can be linked to the electronic tag, enabling it to record critical events during logistics, such as abnormal vibrations, drops, and excessive temperature and humidity. This allows the reusable packaging box to identify and record product-related information and abnormal logistics factors throughout the entire logistics process, synchronizing data with transit stations, distribution centers, or terminal management systems to help identify abnormal products. Managers can use the backend system to trace and analyze historical data, identifying reusable packaging boxes and their contents that have experienced adverse transportation conditions. Timely detection, isolation, or early warning measures can be implemented to effectively reduce the risk of product performance degradation or quality defects caused by improper transportation environments. Simultaneously, it can accurately identify key transportation links that lead to packaging damage or product injury, assisting in determining the cause of damage (e.g., whether due to drops, compression, or moisture). This guides the optimized design of the reusable packaging box structure, such as improvements in the material selection, thickness configuration, and distribution of cushioning pads, effectively enhancing the protective performance and reliability of the reusable packaging box and increasing its reusability.

[0074] The reusable packaging box provided in this embodiment of the utility model features an electronic component compartment on the top cover of the box. Electronic tags and / or environmental sensors are pre-embedded within this compartment, enabling intelligent sensing of the packaging box's identity information and / or the transportation environment. This prevents component damage or data loss during transportation due to external dust, moisture, or mechanical impact. Furthermore, the closable cover and snap-fit ​​structure of the electronic component compartment facilitate the inspection, replacement, or upgrading of the internal electronic tags and / or environmental sensors during the recycling, testing, and maintenance of the reusable packaging box. This enhances the intelligence level and reliability of the reusable packaging box, solving the problems of limited recycling cycles and single functionality in existing packaging boxes.

[0075] Figure 5 This is a schematic diagram of another electronic component compartment provided in an embodiment of the present invention. Figure 6 This is a front view structural diagram of an electronic component compartment provided in an embodiment of the present invention. Figure 7 This is a schematic diagram of another electronic component compartment provided in an embodiment of the present invention. Figure 8 A front view structural diagram of another electronic component compartment provided in an embodiment of this utility model is shown below. Figures 3-8 As shown, in some embodiments, the snap-fit ​​structure 30 includes a hook-type snap-fit ​​structure 30A, a sleeve-type snap-fit ​​structure 30B, or a ball-type snap-fit ​​structure 30C.

[0076] In this embodiment, the latching structure 30 is configured to lock and open the compartment cover 202 by pressing the compartment cover 202 vertically relative to the compartment body 201.

[0077] Specifically, such as Figure 3 and Figure 4 As shown, the hook-type snap-fit ​​structure 30A refers to a snap-fit ​​structure with a hook-like structure (hook) that achieves locking through hooking. The hook-type snap-fit ​​structure 30A is a simple and easy-to-form snap-fit ​​structure. It can directly form the hook and slot on the sheet material through hot pressing or molding processes, without the need for additional parts, with fewer processing steps and high material utilization, thus having lower manufacturing and assembly costs, and is suitable for large-scale reusable packaging applications.

[0078] like Figure 5 and Figure 6 As shown, the sleeve-type snap-fit ​​structure 30B refers to a snap-fit ​​structure that uses the engagement of the engagement post and engagement hole to achieve positioning and locking through plug-in engagement. The sleeve-type snap-fit ​​structure 30B provides a more secure lock, higher stability, more even force distribution, and better sealing.

[0079] like Figure 7 and Figure 8 As shown, the spherical snap-fit ​​structure 30C refers to a snap-fit ​​structure that utilizes the fit between a spherical insertion part and an insertion groove, relying on elastic deformation to achieve locking and unlocking. The spherical snap-fit ​​structure 30C is an elastic plunger structure. When the cover is closed, the spherical insertion part is compressed, undergoes elastic deformation, and slides into the insertion groove. Subsequently, under the action of material rebound force, positioning and locking are achieved. Using the spherical snap-fit ​​structure 30C provides a clear operating feel and precise feedback, reducing the likelihood of errors such as failure to engage, and offering excellent self-locking performance.

[0080] All of the above-mentioned buckle structures can be made of elastic plastic materials (such as polypropylene (PP) or nylon (PA), which can withstand multiple opening and closing operations without plastic deformation or breakage, making them suitable for the high-frequency use requirements of reusable packaging boxes. Users can open the compartment cover 202 without tools by manually pressing or prying it, making operation convenient and maintenance efficient.

[0081] In some embodiments, such as Figure 3 and Figure 4 As shown, the compartment cover 202 is L-shaped and includes an extension arm 2021 bent towards the compartment body 201. The hook-type latch structure 30A includes a hook 301 disposed on the extension arm 2021 and a groove 302 disposed on the side wall of the compartment body 201 and mating with the hook 301. The hook 301 has an inclined guide surface 3011 for guiding engagement and a locking surface 3012 adjacent to the inclined guide surface 3011. When the compartment cover 202 is engaged with the compartment body 201, the locking surface 3012 abuts against the inner wall of the groove 302 to achieve engagement and fixation.

[0082] Specifically, such as Figure 3 and Figure 4As shown, the compartment cover 202 includes a main body 2022 and an extension arm 2021 that bends and extends from one end of the main body 2022 toward the compartment body 201. The extension arm 2021 is disposed opposite to the side wall of the compartment body 201, providing a connection basis for the assembly of the hook-type buckle structure 30A.

[0083] The hook-type buckle structure 30A includes a hook 301 disposed on the surface of the extension arm 2021 near the compartment 201, and a groove 302 disposed on the side wall of the compartment 201 near the extension arm 2021. The outer contour of the hook 301 and the inner cavity structure of the groove 302 are geometrically matched, so that the hook 301 can be smoothly inserted into the groove 302 and form a stable lock after being in place, preventing loosening or falling off.

[0084] Specifically, the hook 301 has an inclined guide surface 3011 that is tilted towards the closing direction, which guides the hook 301 to slide smoothly into the slot 302 during the closing process of the cover 202. The inclined guide surface 3011 is adjacent to a locking surface 3012. When the cover 202 is fully closed, the locking surface 3012 forms a surface contact with the inner wall of the slot 302 and abuts and limits the movement, preventing the cover 202 from accidentally dislodging when subjected to vibration, impact or external pulling, thus achieving reliable locking.

[0085] During the closing process of the cover 202 towards the compartment body 201, the operator applies pressure, causing the inclined guide surface 3011 of the hook 301 to contact the edge of the slot 302. The extension arm 2021 undergoes elastic deformation under pressure. After the hook 301 passes over the inner wall of the slot 302, the locking plane 3012 enters the slot 302 and engages with it due to the rebound force of the material in the extension arm 2021. To open, manual force is applied to cause the extension arm 2021 to elastically deform away from the compartment body 201, thus disengaging the hook 301 from the slot 302 and enabling tool-free opening.

[0086] In some embodiments, such as Figure 3 and Figure 4 As shown, the hook 301 and the extension arm 2021 are integrally molded structures made of elastic plastic materials (such as polypropylene PP or nylon PA) to ensure good locking performance and durability after multiple opening and closing.

[0087] In some embodiments, such as Figure 3 and Figure 4 As shown, the extension arm 2021 is also provided with an opening groove 40, and the opening groove 40 is located on the surface of the extension arm 2021 on the side away from the hook 301.

[0088] The opening groove 40 provides a force application point for the user, facilitating the quick opening of the cover 202.

[0089] Specifically, such as Figure 3 and Figure 4 As shown, the opening groove 40 is located on the outer surface or free end face of the extension arm 2021, and its position is opposite to the hook 301, forming a lever arm structure.

[0090] When it is necessary to open the compartment cover 202, the operator can insert their fingers or a tool (such as a plastic pry bar) into the opening groove 40 and apply force outward, causing the extension arm 2021 to elastically deform and pull the hook 301 out of the slot 302, thus achieving tool-free unlocking. The design of the opening groove 40 makes full use of the lever principle, and the hook 301 and the slot 302 can be separated with a small amount of force, significantly improving the convenience of operation and maintenance efficiency.

[0091] In some embodiments, the opening groove 40 is a partially recessed structure with a cross-sectional shape that can be arc-shaped, U-shaped, or V-shaped, and a moderate depth, ensuring reliable insertion of fingers or tools while avoiding weakening the structural strength of the extension arm 2021 due to excessive depth. The surface of the opening groove 40 can be rounded to improve tactile comfort and prevent stress concentration.

[0092] In some embodiments, such as Figure 5 and Figure 6 As shown, the compartment cover 202 is L-shaped and includes an extension arm 2021 bent towards the compartment body 201. The sleeve-type snap-fit ​​structure 30B includes a snap-fit ​​hole 303 provided on the extension arm 2021 and a snap-fit ​​post 304 provided on the compartment body 201 and matching the snap-fit ​​hole 303. When the compartment cover 202 is snapped into the compartment body 201, the snap-fit ​​post 304 is inserted into the snap-fit ​​hole 303 to achieve snap-fit ​​fixation.

[0093] Specifically, such as Figure 5 and Figure 6 As shown, the cover 202 has an L-shaped structure, including a main body 2022 and an extension arm 2021 that bends and extends from one end of the main body 2022 toward the compartment body 201. The extension arm 2021 is used to form a mating connection area with the compartment body 201 to realize the assembly and locking of the sleeve-type snap-fit ​​structure 30B.

[0094] The sleeve-type snap-fit ​​structure 30B includes a snap-fit ​​hole 303 provided on the extension arm 2021, which can penetrate the extension arm 2021. The sleeve-type snap-fit ​​structure 30B also includes a snap-fit ​​post 304 provided on the side wall of the compartment 201 near the extension arm 2021. The cross-section of the snap-fit ​​post 304 (e.g., circular, square, D-shaped, etc.) matches the inner cavity of the snap-fit ​​hole 303 to avoid loosening or jamming.

[0095] When the cover 202 is pressed down to the closed position, the locking post 304 first contacts the surface of the extension arm 2021 and applies pressure, causing the extension arm 2021 to undergo elastic deformation, resulting in local bending or expansion. As the downward pressure continues, the extension arm 2021 gradually deforms until the locking hole 303 aligns with the locking post 304. At this time, the extension arm 2021 rebounds under the action of the material's elastic restoring force, allowing the locking post 304 to smoothly insert into the locking hole 303, completing the locking action and achieving reliable fixation of the cover 202 and the body 201.

[0096] In some embodiments, the dimensions of the locking hole 303 and the locking post 304 are designed to be interference fit or transition fit to ensure that the connection has sufficient tensile strength and can effectively resist external forces such as vibration and impact during transportation, preventing the cover 202 from being opened accidentally.

[0097] In some embodiments, such as Figure 6 As shown, the front end of the locking post 304 is provided with a guide slope or chamfer 3041, and the entrance of the locking hole 303 is also provided with a corresponding guide structure. The two work together to reduce assembly resistance and improve centering and assembly smoothness.

[0098] Furthermore, when it is necessary to open the compartment cover 202, the operator can apply external force (such as fingers or tools) to the extension arm 2021, causing the extension arm 2021 to elastically deform again, thereby disengaging the locking pin 304 from the locking hole 303 and achieving tool-free disassembly.

[0099] In some embodiments, the compartment body 201 and the locking column 304 are manufactured using an integral molding process. The materials can be selected from engineering plastics such as polypropylene (PP) and nylon (PA) that have excellent elasticity and fatigue resistance, making them suitable for high-frequency opening and closing scenarios of reusable packaging boxes.

[0100] It should be noted that the number of sleeve-type snap-fit ​​structures 30B can be one or more. When there are multiple sleeve-type snap-fit ​​structures 30B, the multiple sleeve-type snap-fit ​​structures 30B can be arranged at intervals along the edge distribution direction of the cover 202 and the body 201 to achieve multi-point uniform locking between the cover 202 and the body 201.

[0101] The number of sleeve-type snap-fit ​​structures 30B can be 2, 3, 4 or more, preferably 2 to 4 arranged at equal intervals, to balance connection reliability and ease of assembly. Figure 5 and Figure 6 The illustration is based on an example of three 30B sleeve-type snap-fit ​​structures, but it is not limited to this.

[0102] In some embodiments, such as Figure 5 and Figure 6As shown, an inclined surface 41 is formed at the bottom of the extension arm 2021, and the angle between the inclined surface 41 and the side wall of the extension arm 2021 on the side away from the compartment 201 is an acute angle.

[0103] Specifically, such as Figure 5 As shown, the inclined surface 41 is provided on the lower surface of the free end of the extension arm 2021 and extends inclinedly toward the closing direction of the compartment 201. When the compartment cover 202 is pressed down to the closed position, the inclined surface 41 first contacts the side wall of the compartment 201 or the locking structure (such as the top of the locking post 304) to form an inclined guide fit.

[0104] Under continuous downward pressure, the inclined surface 41 slides along the contact surface and generates a normal component force, forcing the extension arm 2021 to undergo elastic deformation, thereby making room for the locking post 304 to enter the locking hole 303. As the cover 202 continues to press down, the extension arm 2021 gradually returns to its original position under the action of the material's elastic restoring force, ultimately achieving alignment and insertion of the locking post 304 and the locking hole 303, completing the locking action.

[0105] The inclined surface 41 serves as an active guiding structure, significantly improving the assembly smoothness and alignment of the sleeve-type snap-fit ​​structure 30B, effectively reducing closing resistance, and preventing structural damage caused by misalignment or jamming. It is especially suitable for cyclic packaging scenarios with high-frequency manual operations.

[0106] Meanwhile, when the cover 202 is closed, a preset gap or operating space is formed between the inclined surface 41 and the side wall of the body 201. This space extends along the bottom of the extension arm 2021 toward the body 201, forming a force application area that facilitates the operator to open the cover 202.

[0107] Specifically, when the cover 202 is fully engaged with the body 201, the inclined surface 41 does not completely adhere to the surface of the body 201, but leaves a certain gap, creating an operating channel below the free end of the extension arm 2021 for inserting fingertips or simple tools (such as plastic pry bars). The operator can apply upward prying force through this space, causing the extension arm 2021 to elastically deform, thereby disengaging the engaging hole 303 and the engaging post 304, achieving tool-free opening.

[0108] In some embodiments, the angle between the inclined surface 41 and the side wall of the extension arm 2021 on the side away from the compartment 201 ranges from 30° to 75°, more preferably from 45° to 60°. This angle design can ensure sufficient guide stroke and ensure that the finger or tool can be inserted smoothly, while avoiding contact stress concentration due to too small an angle or weakening of the guide effect due to too large an angle.

[0109] In some embodiments, such as Figure 7 and Figure 8As shown, the spherical snap-fit ​​structure 30C includes a spherical insertion portion 305 disposed on the compartment cover 202 and an insertion groove 306 disposed on the compartment body 201 and matching the spherical insertion portion 305. When the compartment cover 202 is engaged with the compartment body 201, the spherical insertion portion 305 is engaged in the insertion groove 306.

[0110] Among them, such as Figure 7 and Figure 8 As shown, the spherical snap-fit ​​structure 30C includes a spherical insertion part 305 disposed at the bottom edge of the compartment cover 202, and an insertion groove 306 disposed on the compartment body 201 opposite to the spherical insertion part 305. The outer contour of the spherical insertion part 305 is a hemispherical or near-spherical protrusion structure, and the outer contour shape of the spherical insertion part 305 and the inner cavity structure of the insertion groove 306 are adapted to each other in terms of geometric dimensions, curvature and spatial position, so that the ball head of the spherical insertion part 305 can smoothly slide into the insertion groove 306 and be effectively locked, forming a stable connection.

[0111] When the cover 202 is pressed down, the spherical insertion part 305 first contacts the inlet end of the insertion groove 306 and applies pressure, causing the spherical insertion part 305 and / or the insertion groove 306 to undergo elastic deformation, making room for the assembly of the spherical insertion part 305. As the downward pressure continues, the spherical insertion part 305 slides along the inlet of the insertion groove 306 and gradually enters the interior of the insertion groove 306. After the spherical insertion part 305 is inserted into place, the spherical insertion part 305 and / or the insertion groove 306 restore their shape under the action of the material's elastic restoring force, so that the spherical insertion part 305 is completely locked into the insertion groove 306, achieving a stable lock.

[0112] In some embodiments, the insertion groove 306 has a chamfered or flared structure at the entrance, and the insertion groove 306 and the arc surface of the spherical insertion part 305 work together to achieve automatic centering and smooth assembly.

[0113] When it is necessary to open the compartment cover 202, the operator can apply an upward pulling force to the compartment cover 202 with their fingers or tools, so that the spherical insertion part 305 and / or insertion groove 306 will elastically deform again, causing the spherical insertion part 305 to disengage from the insertion groove 306, thus completing tool-free disassembly.

[0114] In some embodiments, by designing a continuous arc-shaped insertion groove 306 along the closing direction, the spherical insertion part 305 can be engaged at different positions, thereby supporting stepless adjustment or positional positioning of the opening angle of the cover 202, meeting the opening requirements of different usage scenarios (such as half-open and fully open states).

[0115] In some embodiments, the cover 202 and the spherical insertion part 305 are integrally molded structures made of elastic engineering plastic materials, such as polypropylene (PP) and nylon (PA), so that the cover 202 body and the spherical insertion part 305 form an integral structure without welds or splices. This not only ensures the integrity and mechanical strength of the structure, but also ensures that the spherical insertion part 305 has good elastic deformation ability and rebound recovery performance during repeated engagement and disengagement.

[0116] In some embodiments, such as Figure 7 and Figure 8 As shown, a prying groove 42 is provided on the surface of the compartment body 201 near the compartment cover 202, and an insertion groove 306 is provided on the bottom surface of the prying groove 42, that is, in its inner cavity area.

[0117] Specifically, when the cover 202 is closed and locked to the body 201, the edge of the cover 202 covers the pry-open groove 42 but does not completely fit it, thus creating a gap between the cover 202 and the body 201. This gap provides an operating channel for the operator to insert their fingers or simple tools (such as a plastic pry bar).

[0118] When it is necessary to open the compartment cover 202, the operator can insert their fingers or tools into the opening end of the pry groove 42 and apply upward prying force to the edge of the compartment cover 202, so that the ball-shaped insertion part 305 is disengaged from the insertion groove 306, thereby achieving tool-free quick disassembly.

[0119] In some embodiments, the depth of the pry groove 42 is 1 mm to 5 mm, the width is adapted to the size of a finger or commonly used tool, and its opening edge is chamfered or rounded to improve operating comfort and prevent stress concentration.

[0120] Understandably, the design of the hook-type snap-fit ​​structure 30A, sleeve-type snap-fit ​​structure 30B, or ball-type snap-fit ​​structure 30C not only enables the quick locking and convenient opening of the cover 202, but also has good vibration resistance and sealing stability, effectively preventing the cover 202 from loosening or electronic components from being exposed due to bumps during transportation, thus improving the overall protection level and reliability of the electronic component compartment 20.

[0121] Figure 9 This is a schematic diagram of another reusable packaging box provided in an embodiment of the present invention. Figure 10 for Figure 9 Enlarged structural diagram at point B Figure 11 and Figure 12 A schematic diagram of a plate-like structure of a reusable packaging box provided for an embodiment of this utility model, as shown below. Figures 9-12 As shown, optionally, the plate structure of the box body 10 is a polypropylene hollow plate, and the polypropylene hollow plate is pressed with creases 50 for folding.

[0122] Specifically, the box 10 is rectangular in shape and is composed of a continuous plate-like structure. Its main material is polypropylene hollow board (PP hollow board). PP hollow board is made of high-density polypropylene (PP) through an extrusion molding process. It has the advantages of being pollution-free, recyclable, corrosion-resistant, waterproof, shockproof, supporting surface printing, lightweight, and high-strength. It is suitable for logistics packaging scenarios with high-frequency recycling.

[0123] The polypropylene hollow sheet is pressed with creases 50 for folding, also known as indentation lines or crease lines. These creases 50 are formed on the surface of the sheet by die rolling or hot pressing to create a locally thinned groove structure that extends along the predetermined folding direction, serving as a reference line for bending between the various surfaces of the box 10.

[0124] The 50mm depth of the pressure line is controlled to ensure that the board can be folded precisely along the pressure line when bending force is applied, without affecting the overall structural strength. After folding, the edges are neat and the angle is stable, avoiding cracking or deformation of the board due to stress concentration.

[0125] like Figures 9-12 As shown, by setting multiple parallel or intersecting pressure lines 50, the entire polypropylene hollow board can be folded into components such as the top cover plate 101, bottom plate 102, and side plate 103 of the box body 10, realizing an integrated folding box structure without additional splicing or welding, which significantly simplifies the assembly process and improves production efficiency and structural integrity.

[0126] Figure 13 A schematic diagram of a folding hinge provided for an embodiment of this utility model is shown below. Figure 9 , Figure 10 and Figure 13 As shown, the housing 10 also includes a bottom plate 102 disposed opposite to the top cover plate 101, and a side plate 103 connecting the top cover plate 101 and the bottom plate 102. A folding hinge 43 is provided at the vertical edge of the side plate 103.

[0127] Specifically, such as Figures 9-13 As shown, the top cover 101, bottom plate 102, and side plates 103 are folded to form a closed cuboid structure, constituting the box 10. The side plates 103 are continuously arranged around the circumference of the box 10, including a front side plate, a rear side plate, a left side plate, and a right side plate. The pressure lines between adjacent side plates 103 are the vertical edge pressure lines of the side plates 103. These vertical edge pressure lines extend along the height direction of the box and, after folding, form the four vertical edges (i.e., vertical ridges) of the box.

[0128] A folding hinge 43 is pre-embedded at the vertical edge pressure line. The folding hinge 43 is a mechanical device that allows two parts to rotate relative to each other along the hinge axis to achieve the folding function. The folding hinge 43 can be a strip or sheet structure, which can be made of thermoplastic polyurethane (TPU), polypropylene (PP) or metal sheet. Its two ends are fixed to the adjacent side plate 103, and it can rotate in the middle.

[0129] The function of the folding hinge 43 is to enhance the structural strength of the vertical edges and prevent material fatigue cracking caused by repeated folding. Simultaneously, the folding hinge 43 has a certain limiting function, maintaining a stable bending angle after the box body 10 is folded and formed, avoiding edge springback due to material elasticity recovery, and ensuring the box structure is stable and tightly closed. In this embodiment, strengthening the box body through the folding hinge structure allows for more repeated use (30 times or more), making the cost per packaging unit lower than the cost of traditional disposable cardboard boxes, thus reducing packaging costs.

[0130] In some embodiments, such as Figure 13 As shown, the folding hinge 43 includes two symmetrically arranged connecting plates 431 and a rotating shaft 432 located between them. The connecting plates 431 are respectively connected to two adjacent side plates 103, and each connecting plate 431 is provided with at least two through holes 433, which can be used as mounting and fixing points (such as screw holes). The two ends of the rotating shaft 432 are respectively fixed to the inner sides of the two connecting plates 431, and the two connecting plates 431 can rotate around the rotating shaft 432, so that the connecting plates 431 can achieve a folding action of more than 90° at the vertical edge pressing line.

[0131] In some embodiments, the folding hinge 43 is embedded between the wall layers of the polypropylene hollow board during the manufacturing stage and integrally formed with the box body through hot pressing or injection molding processes, eliminating the need for subsequent assembly, resulting in a reliable structure and high production efficiency.

[0132] In some embodiments, such as Figure 9 As shown, the housing 10 includes 4 vertical ridge lines, and each vertical ridge line is provided with at least one folding hinge 43, so that the edge structure strength can be enhanced at each vertical ridge line, preventing folding and springback, and supporting multiple cycles of use.

[0133] For example, such as Figure 9 As shown, taking the setting of two folding hinges 43 for each vertical edge pressure line as an example, the two folding hinges 43 are distributed at intervals along the vertical edge pressure line direction to enhance the strength of the edge structure, improve the bending stiffness, and prevent folding rebound caused by material elasticity, but it is not limited to this.

[0134] In some embodiments, such as Figure 9As shown, folding hinges 43 are arranged at the eight corners of the housing 10, that is, at each vertex position (i.e., the four upper corners and the four lower corners), a folding hinge 43 is provided to set up a reinforcing structure in the key stress area of ​​the housing 10, strengthen the structural strength of the vertex position, and increase the number of cycles.

[0135] It should be noted that although the illustrations may show a specific number and configuration of folding hinges 43, the present invention is not limited to the specific embodiment shown. In other embodiments, the number, size, and installation position of the folding hinges 43 can be adjusted according to the needs of the actual application scenario, and these variations are all within the protection scope of the present invention.

[0136] In some embodiments, such as Figures 9-12 As shown, the housing 10 also includes a bottom plate 102 disposed opposite to the top cover plate 101, and a side plate 103 connected between the top cover plate 101 and the bottom plate 102. The top cover plate 101 and the side plate 103, as well as the bottom plate 102 and the side plate 103, are detachably locked together by a locking structure 60.

[0137] Among them, a locking structure 60 is provided between the top cover plate 101 and the side plate 103, and between the bottom plate 102 and the side plate 103, to realize a detachable locking connection between adjacent plates, so as to replace the traditional tape sealing and support the multiple recycling of the packaging box.

[0138] In some embodiments, such as Figures 9-12 As shown, the locking structure 60 includes a first latch 601 disposed at the free end of the upper cover plate 101 and a first latch 602 disposed at the corresponding position of the top edge of the side plate 103. When the upper cover plate 101 is folded down to the side plate 103, the first latch 602 is inserted into the first latch 601 to form a limit lock, preventing the upper cover plate 101 from being opened accidentally.

[0139] Similarly, such as Figures 9-12 As shown, the locking structure 60 also includes a second latch 603 located at the free end of the base plate 102 and a second latch 604 located at the corresponding position on the bottom edge of the side plate 103. When the base plate 102 is folded upward to the side plate 103, the second latch 604 is inserted into the second latch 603 to form a limit lock, preventing the upper base plate 102 from being opened accidentally.

[0140] In some embodiments, such as Figures 9-12As shown, two locking structures 60 are provided between the top cover plate 101 and the side plate 103, and two locking structures 60 are provided between the bottom plate 102 and the side plate 103, for a total of four sets of locking structures 60, which improve the closing strength and sealing performance. However, it is not limited to this. In different application scenarios or for boxes 10 of different sizes and uses, the number and position of the locking structures 60 can be adjusted as needed to achieve the best use effect and economic benefits.

[0141] In some embodiments, such as Figure 1 , Figure 9 , Figure 11 and Figure 12 As shown, at least two opposite side plates 103 of the housing 10 are provided with handle holes 70, which are used for the operator's hands to pass through, so as to facilitate handling.

[0142] The handle hole 70 penetrates the side plate 103 and is preferably elliptical, circular, or racetrack-shaped, with rounded edges to improve grip comfort and prevent scratches.

[0143] In this embodiment, by integrating a handle hole 70 structure on the side plate 103, a lightweight, low-cost, and highly available handling function can be achieved without the need for additional handles or accessories.

[0144] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
