Description

Technical Field

[0001] This application relates to the technical field of packaging materials, and in particular to an aircraft case, a packaging structure for a display device, and a display device. Background Technology

[0002] Flight cases are sturdy and durable packaging containers designed specifically for air transport. They are fireproof, waterproof, shockproof, and easy to maneuver. They can solve the problems of insufficient protection and poor mobility of traditional simple wooden boxes in long-distance transportation. They are mainly used to protect the safety of high-tech products (such as displays) and precision equipment during long-distance transportation.

[0003] In traditional technology, flight cases have complex structural designs and many components, making installation complicated, time-consuming, and labor-intensive. Furthermore, when using flight cases to package and transport large-sized displays, they cannot effectively restrain the displays, making them prone to loosening and damage during transportation, posing significant safety hazards. Utility Model Content

[0004] Therefore, it is necessary to provide a flight case, display device packaging structure, and display device to address the problems of complex installation and operation, time-consuming and labor-intensive operation, poor limit reliability, and susceptibility to collision damage caused by traditional technologies.

[0005] A first aspect of this application provides an aviation case comprising:

[0006] The housing has an internal cavity.

[0007] A base, connected to the housing, has a recessed receiving groove communicating with a receiving cavity, and the receiving groove and the receiving cavity cooperate to jointly accommodate at least a portion of the display device. A limiting mechanism is provided on the base for limiting cooperation with the display device.

[0008] A locking plate is connected to the housing base and the housing body. The locking plate covers the opening of the receiving groove, so that the locking plate and the housing base cooperate to limit the display device.

[0009] This flight case solution can be used in scenarios where display devices are packaged and protected, ensuring their safety during transportation. Specifically, when assembling the flight case and display device, the display device is first installed onto the case base, that is, the display device is pushed into the receiving slot of the case base, and the display device is installed with the limiting mechanism pre-installed on the case base. The limiting mechanism can reliably limit the display device. Next, the locking plate is assembled onto the case base, and the locking plate seals the opening of the receiving slot, thus forming a locking plate and case base that enclose and restrain the display device in the circumferentially closed receiving slot, thereby further restricting the display device's freedom of movement and improving the stability of the display device installation. Finally, the case is covered. The display device is installed in the housing cavity of the case to encapsulate it. The case is then connected and secured to the base and locking plate to ensure structural stability. This completes the assembly of the display device and the flight case. Compared to traditional technologies, this application, on the one hand, utilizes the enclosure and constraint of the locking plate and base, and the limiting mechanism to restrict the display device's freedom of movement, preventing it from shaking and being damaged during transport, thus eliminating potential safety hazards. On the other hand, the entire flight case consists of only three components: the base, the locking plate, and the case body. The fewer components and simpler installation steps make the operation time-saving and labor-saving.

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] In the existing technology, the flight case 100 has a complex structural design and many components, making installation complicated, time-consuming and labor-intensive. Furthermore, when using the flight case 100 to package and transport a large-sized display screen 230, it cannot effectively limit the display screen 230, making it prone to loosening and collision damage during transportation, posing a significant safety hazard.

[0052] To address the aforementioned issues, this application optimizes the structure by assembling the flight case 100 into three components: the case body 10, the case base 20, and the locking plate 30. This significantly reduces the number of components, thereby reducing installation steps, lowering installation difficulty, and saving labor intensity for installers. Furthermore, by setting a limiting mechanism 40 on the case base 20, connecting the limiting mechanism 40 to the display device 200, and simultaneously using the case base 20 and the locking plate 30 to enclose and constrain the display device 200, the freedom of the display device 200 can be effectively limited, ensuring that the display device 200 is securely installed within the flight case 100 and preventing collision damage.

[0053] See Figures 1 to 4 The present application describes a display device packaging structure comprising a flight case 100 and a display device 200. At least a portion of the display device 200 is housed within the flight case 100, and the display device 200 is connected to a limiting mechanism 40. The flight case 100 encloses at least a portion of the display device 200, thus providing packaging protection for the display device 200 and ensuring its safety during transportation.

[0054] Please continue reading. Figure 1 and Figure 2 In this application, the flight case 100 includes a case body 10, a case base 20, and a locking plate 30. For example, the flight case 100 has a rectangular parallelepiped structure, which is simple and regular, making it convenient to stack multiple flight cases 100 during transportation to improve the utilization of installation space.

[0055] Optionally, the flight case 100 is assembled from materials such as aluminum alloy and fireproof board, thus possessing excellent structural strength and fire resistance and impact resistance.

[0056] Please continue reading. Figure 3 , Figure 4 and Figures 6 to 7 The cabinet 10 has an internal cavity 11; the cabinet base 20 is connected to the cabinet 10, and the cabinet base 20 has a recessed receiving groove 21. The receiving groove 21 communicates with the receiving cavity 11, and the receiving groove 21 and the receiving cavity 11 cooperate to accommodate at least a part of the display device 200. The cabinet base 20 is provided with a limiting mechanism 40, which is used to limit the display device 200; the locking plate 30 is connected to the cabinet base 20 and the cabinet 10, and the locking plate 30 covers the opening of the receiving groove 21, so that the locking plate 30 and the cabinet base 20 cooperate to limit the display device 200.

[0057] In addition, in order to further improve the anti-collision performance of the flight case 100 and thus prevent the impact of the collision from damaging the display device 200 inside the flight case 100, in another embodiment, the outer wall of the case 10 is provided with a first buffer; and / or, the outer wall of the case base 20 is provided with a second buffer; and / or, the outer wall of the lock plate 30 is provided with a third buffer.

[0058] Optionally, the first, second, and third buffers mentioned above are present simultaneously, so that when the flight cases 100 collide with each other or with other objects in the environment, the first and / or second and / or third buffers can form a good buffering and shock absorption effect, reducing the impact damage to the flight cases 100 and the display device 200.

[0059] For example, the first buffer is located on the side and / or edge and / or top corner of the housing 10. The second buffer is located on the side and / or edge and / or top corner of the housing base 20. The third buffer is located on the side and / or edge and / or top corner of the locking plate 30.

[0060] For example, the first, second, and third buffer components can be any of the following: rubber strips, foam, etc., and can be flexibly selected according to actual needs.

[0061] Please continue reading. Figure 2 and Figure 7 Furthermore, in one embodiment, the side of the case base 20 away from the case body 10 is provided with a first moving wheel 14; the outer peripheral wall of the case body 10 is provided with a plurality of handles 15 distributed circumferentially. The first moving wheel 14 provides the flight case 100 with freedom of movement and maneuverability, facilitating transportation and relocation; the handles 15 facilitate the installation personnel to push and pull the flight case 100.

[0062] Please continue reading. Figures 3 to 6 More specifically, in one embodiment, the display device 200 is a display screen device. That is, the display device 200 includes a movable base 210, a lifting bracket 220, and a display screen 230. The movable base 210 is provided with second movable wheels 213. The lifting bracket 220 is mounted on the movable base 210. The display screen 230 is connected to the lifting bracket 220. The lifting bracket 220 and the display screen 230 are connected to the limiting mechanism 40.

[0063] After the display device 200 is assembled with the packaging box, the movable base 210 extends from the receiving slot 21 to the bottom of the flight case 100. The second movable wheel 213 and the first movable wheel 14 simultaneously contact the ground, providing better support to ensure the flight case 100 moves stably and avoids tipping over. On the other hand, it also provides support for the display device 200, reduces the force on the limiting mechanism 40, and protects the limiting mechanism 40 from deformation, breakage, or other structural damage.

[0064] Optionally, more than one first moving wheel 14 and second moving wheel 213 can be set, and the specific selection can be made flexibly according to actual needs.

[0065] By pre-installing the display screen 230 onto the lifting bracket 220, the mobile base 210 provides a convenient means of transporting and moving large-sized and heavy displays without the need for on-site lifting equipment, thus reducing operating costs and improving the operability of the display device 200 and the flight case 100 packaging.

[0066] During the movement of the display screen 230, the lifting bracket 220 drives the display screen 230 to a raised position. When the moving base 210 moves to the bottom of the packaging box, and the lifting bracket 220 extends into the preset position in the receiving slot 21, the lifting bracket 220 then drives the display screen 230 to descend, so that the display screen 230 and the lifting bracket 220 are simultaneously connected to the limiting mechanism 40, thereby enabling the limiting mechanism 40 to position the display device 200.

[0067] It should be noted that after the packaging box and display device 200 are assembled, the display screen 230 is entirely located within the receiving cavity 11 of the housing 10, which provides protection for it. The part of the lifting bracket 220 used to connect with the display screen 230 is also located within the receiving cavity 11 of the housing 10, while the rest of the lifting bracket 220 is located in the receiving groove 21, which is a ring-shaped closed structure enclosed by the housing base 20 and the locking plate 30.

[0068] For example, the lifting support 220 includes two horizontally spaced columns and a lifting drive device installed on the two columns. The lifting drive device is connected to the display screen 230, so that the display screen 230 has its own lifting capability, eliminating the need for on-site lifting equipment, reducing costs and improving installation convenience and efficiency.

[0069] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: The flight case 100 of this solution can be applied to scenarios where the display device 200 is packaged and protected, ensuring the safety of the display device 200 during transportation; specifically, when assembling the flight case 100 and the display device 200, the display device 200 is first installed on the case base 20, that is, the display device 200 is pushed into the receiving slot 21 of the case base 20, and the display device 200 is installed with the limiting mechanism 40 preset on the case base 20. The limiting mechanism 40 can form a reliable limiting effect on the display device 200; then, the locking plate 30 is assembled onto the case base 20, and the locking plate is used to lock the display device 200. Plate 30 covers the opening of the receiving slot 21, thereby forming a locking plate 30 that cooperates with the housing base 20 to enclose and constrain the display device 200 in the circumferentially closed receiving slot 21, thereby further restricting the degree of freedom of movement of the display device 200 and improving the stability of the display device 200 installation; finally, the housing 10 is placed on the display device 200, and the display device 200 is installed in the receiving cavity 11 of the housing 10 to realize the enclosure of the display device 200 by the housing 10. Then, the housing 10 is connected and fixed to the housing base 20 and the locking plate 30 respectively to ensure the stability of the housing 10 structure. At this point, the assembly operation of the display device 200 and the flight case 100 is completed.

[0070] Compared with traditional technologies, this application, on the one hand, utilizes the enclosure and constraint of the display device 200 by the locking plate 30 and the locking seat, and the limiting mechanism 40 to limit the display device 200, which can effectively restrict the degree of freedom of movement of the display device 200, prevent the display device 200 from shaking and being damaged by collision during transportation, and eliminate potential safety hazards of product damage; on the other hand, the entire flight case 100 consists of only three components: the case base 20, the locking plate 30, and the case body 10. The number of components is small, the installation steps are simple, and the operation is time-saving and labor-saving.

[0071] Please continue reading. Figures 3 to 5 Specifically, in one embodiment, the housing 20 is provided with a surrounding plate 25 for enclosing and forming a receiving groove 21, and the limiting mechanism 40 includes a first limiting member 41, which is mounted on the surrounding plate 25 and protrudes toward the groove cavity of the receiving groove 21. The first limiting member 41 is used to limit and cooperate with the lifting bracket 220 of the display device 200.

[0072] The enclosure 25 provides a stable and reliable fixation for the first limiting member 41, ensuring that the first limiting member 41 has sufficient strength. Since the first limiting member 41 protrudes towards the cavity of the receiving groove 21, after the display device 200 is pushed laterally into the receiving groove 21, the first limiting member 41 can directly connect to the column of the lifting bracket 220 to achieve positioning of the display device 200. The structural and positional design of the first limiting member 41 achieves automatic positioning of the display device 200, eliminating the need for manual operation and resulting in high automation and efficiency.

[0073] Please continue reading. Figure 5 Specifically, in an optional embodiment, the first limiting member 41 includes a first limiting plate 411 and a second limiting plate 412. The first limiting plate 411 and the second limiting plate 412 are arranged side by side at intervals to form a limiting groove 413, which is used to engage the column of the lifting bracket 220. After the display device 200 is pushed laterally into the receiving groove 21, the column is directly engaged in the limiting groove 413. The first limiting plate 411 and the second limiting plate 412 apply a holding force to the column to position it and limit the display device 200.

[0074] Optionally, the first limiting plate 411 and the second limiting plate 412 are arranged in a flared shape, which makes the opening diameter of the limiting groove 413 larger, ensuring that even if there is a certain positional deviation when the display device 200 enters the receiving groove 21, the column can be smoothly inserted into the limiting groove 413.

[0075] Please continue reading. Figures 3 to 5 Furthermore, based on the above embodiments, the limiting mechanism 40 also includes a second limiting member 42. The second limiting member 42 is installed on the enclosure 25 and protrudes towards the receiving cavity 11. The second limiting member 42 is used to limit the display screen 230 of the display device 200. When the display device 200 enters the preset position in the receiving groove 21 and the column is locked in place by the first limiting member 41, the lifting drive device is controlled to drive the display screen 230 to descend, so that the display screen 230 can be automatically connected to the second limiting member 42, thereby realizing the positioning of the display screen 230 by the second limiting member 42 and further enhancing the limiting reliability of the display device 200.

[0076] Specifically, in one embodiment, the second limiting member 42 is a limiting tongue, which is used to insert and limit the display screen 230 through a preset limiting hole 230a. Alternatively, as an optional implementation, the second limiting member 42 may be a limiting hole 230a, which is used to insert and limit the display screen 230 through a preset limiting tongue.

[0077] When the display screen 230 descends, the limiting tongue plate will automatically insert into the corresponding limiting hole 230a. The limiting tongue plate will lock into the wall of the limiting hole 230a to restrict the freedom of movement of the display screen 230 and prevent the display screen 230 from shaking and being damaged by collision during transportation due to vibration and collision.

[0078] To enhance the limiting effect on the display screen 230, the limiting tongue and the limiting hole 230a can be set in two or more at the same time, and the two are assembled in a one-to-one correspondence.

[0079] Please continue reading. Figure 3 and Figure 7 In one embodiment, a guide mechanism 23 is provided on the side of the base 20 away from the housing 10. The guide mechanism 23 is used to guide and cooperate with the guide rail 214 on the movable base 210 of the display device 200. This guide mechanism plays a guiding role when the base 20 and the display device 200 are assembled together, thereby improving the installation accuracy.

[0080] Specifically, in one embodiment, the guiding mechanism 23 includes a bracket 231 and a plurality of rolling elements 232. The bracket 231 is disposed on the housing 20, and the plurality of rolling elements 232 are rotatably mounted side by side on the bracket 231. The rolling elements 232 are used to roll in contact with the guide rail 214. During the process of pushing the display device 200 into the housing 20, the guide rail 214 and the plurality of rolling elements 232 arranged side by side roll in contact with each other. The rolling elements 232 not only guide the display device 200, but also reduce frictional resistance, allowing the installer to push the display device 200 into place smoothly with less force, thus improving installation efficiency and user experience.

[0081] Furthermore, in an optional embodiment, a first functional block 24 is provided on the side of the base 20 away from the housing 10, and the first functional block 24 is provided with a first positioning part 241. A second functional block 31 is provided on the side of the locking plate 30 away from the housing 10, and the second functional block 31 is provided with a second positioning part 311. The first positioning part 241 and the second positioning part 311 are spaced apart. The first positioning part 241 is used to engage with a first mating part 211 on the movable base 210 of the display device 200, and the second positioning part 311 is used to engage with a second mating part 212 on the movable base 210 of the display device 200.

[0082] The first positioning part 241 and the first mating part 211, as well as the second positioning part 311 and the second mating part 212, are adapted and fitted together to achieve the effect of assembly positioning, ensuring the installation position accuracy and assembly reliability of the housing 20, display device 200, and locking plate 30. For example, in this application, both the first positioning part 241 and the second positioning part 311 are arc-shaped convex surfaces, and both the first mating part 211 and the second mating part 212 are arc-shaped concave surfaces. The arc-shaped convex surfaces and arc-shaped concave surfaces adopt a contour-following design, so they fit together after assembly to achieve a better positioning effect.

[0083] In order to ensure that the first positioning part 241 and the first mating part 211, as well as the second positioning part 311 and the second mating part 212, can effectively abut and fit together, based on the above embodiment, the side of the first functional block 24 away from the housing 10 extends beyond the side of the movable base 210 away from the housing 10, and the side of the second functional block 31 away from the housing 10 extends beyond the side of the movable base 210 away from the housing 10.

[0084] By ensuring that the side of the first functional block 24 away from the housing 10 extends beyond the side of the movable base 210 away from the housing 10, the first positioning part 241 can be guaranteed to have a certain protrusion height. This allows it to effectively align with the first mating part 211 along the assembly direction, ultimately ensuring sufficient contact area between the first positioning part 241 and the first mating part 211, resulting in a more reliable positioning effect. Similarly, by ensuring that the side of the second functional block 31 away from the housing 10 extends beyond the side of the movable base 210 away from the housing 10, the second positioning part 311 can be guaranteed to have a certain protrusion height. This allows it to effectively align with the second mating part 212 along the assembly direction, ultimately ensuring sufficient contact area between the second positioning part 311 and the second mating part 212, resulting in a more reliable positioning effect.

Figure 2 and Figure 4 For the display device 200, it is usually necessary to configure accessories such as power cord and handheld remote control for the display screen 230. In order to facilitate the installation of these accessories, in one embodiment, the base 20 is provided with a plurality of compartments 22 on the side facing the housing 10. The compartments 22 are used to accommodate the accessory box of the display device 200.

[0086] As is easily understood, the accessory box specifically includes the packaging carton and the accessories installed inside the packaging carton.

[0087] The area and depth of each compartment 22 can be different so as to accommodate different accessory boxes of different sizes.

[0088] It should be noted that there are multiple ways to install and fix the parts box in the compartment 22. For example, the inner wall of the compartment 22 can be clamped to the outer wall of the parts box to achieve a tight fixation, or straps can be set in the compartment 22 and the parts box can be fixed by strapping, etc. The specific method can be flexibly selected according to the actual needs, and no specific limitation is made here.

[0089] In this application, the cabinet 10 has a cuboid structure, and one side of the cabinet 10 has an opening to allow the accommodating cavity 11 to communicate with the external environment through the opening. When the cabinet 10 is installed, the upper part of the display device 200 extends into the accommodating cavity 11 through the opening, so that the cabinet 10 is fitted onto the outside of the display device 200.

[0090] Please continue reading. Figure 1 and Figure 2In one embodiment, the housing 10 includes a first cover 12 and a second cover 13, which are detachably connected by a first lock 50. The first cover 12 and the second cover 13 cooperate to form a receiving cavity 11. Designing the housing 10 with separate first and second covers 12 and 13 results in smaller size and lighter weight for the first and second covers 12 and 13, making it easier for installers to assemble and disassemble, reducing labor intensity, and saving physical strength.

[0091] The first lock 50 can lock the first cover 12 and the second cover 13 together, so that the case 10 can form a protective shield for the display device 200. When the flight case 100 arrives at its destination, the first lock 50 unlocks the first cover 12 and the second cover 13, and the first cover 12 and the second cover 13 are separated, so that the display device 200 can be easily taken out from the flight case 100.

[0092] For example, the first lock 50 can be any type of mechanical lock, electromagnetic lock, etc., and can be flexibly selected according to actual needs.

[0093] Furthermore, in yet another embodiment, the base 20 and the locking plate 30 are detachably connected by a second lock 60; the first cover 12 and the base 20 are detachably connected by a third lock 70; and the second cover 13 and the locking plate 30 are detachably connected by a fourth lock 80.

[0094] Therefore, by setting the second lock 60, the third lock 70, and the fourth lock 80, all the components of the separately configured flight case 100 can be locked and fixed together, so that the flight case 100 has a more stable overall structure, improves the pressure resistance and impact resistance of the flight case 100, and forms a more reliable protection for the display device 200. At the same time, it also facilitates the disassembly of each component to remove the display device 200 from the flight case 100 for use.

[0095] The second lock 60, the third lock 70, and the fourth lock 80 can also be any type of mechanical lock, electromagnetic lock, etc., and the choice is flexible and not specifically limited here.

[0096] It should also be noted that the types of the first lock 50, the second lock 60, the third lock 70, and the fourth lock 80 can be the same or different, and you can choose flexibly.

[0097] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0098] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
