[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-5 As shown, this invention illustrates a foldable teaching integration box in one embodiment of the present invention, used to install several multimedia modules 1. It includes a box body 2, with a mounting frame 3 hinged to one side wall of the top of the box body 2. A display screen 4 is installed inside the mounting frame 3, and the display screen 4 is electrically connected to the multimedia modules 1. The display screen 4 is used to cover the box body 2, and can also be vertically rotated around the hinge axis to open. The box body 2 has multiple installation areas. Several mounting seats 5 are provided, each located inside the box body 2, with each mounting seat 5 corresponding to one of the installation areas. Elastic shock-absorbing pads are provided inside each mounting seat 5, and a multimedia module 1 can be detachably mounted on each mounting seat 5.

[0027] Specifically, the top side wall of the cabinet 2 is hinged to the mounting frame 3. The high-definition display screen 4 is fixed inside the mounting frame 3, and the size of the display screen 4 matches the top surface of the cabinet 2 and can be vertically deflected around the hinge. The cabinet 2 is divided into multiple independent installation areas by partitions, and each area corresponds to a mounting seat 5. The inner wall of the mounting seat 5 is pasted with an elastic shockproof pad with an anti-slip treatment. The side wall is also provided with buckles that can be snapped and fixed to the edge of the multimedia module 1.

[0028] During transportation or storage, because the multimedia module 1 is installed inside the mounting base 5, the elastic shock-absorbing pad inside the mounting base 5 will wrap around the multimedia module 1. When storing, rotate the mounting frame 3 around the hinge to make the display screen 4 fit against the top surface of the cabinet 2 to complete the seal. When in use, rotate the mounting frame 3 upward around the hinge to the appropriate viewing angle, and connect the display screen 4 and the multimedia module 1 through the wire. After the module is started, the content will be displayed on the display screen 4. If the module needs to be maintained, it can be disassembled by loosening the buckle of the mounting base 5.

[0029] With the integrated display screen 4 and multimedia module 1 installation structure, each multimedia module 1 is integrated and installed in the box 2, which can be used immediately after opening the box. This effectively adapts to the urgency of military missions and solves the problem of low deployment efficiency. The elastic shock-absorbing pad can buffer the bumps during transportation and avoid damage to precision components. The box 2 itself is impact-resistant and can adapt to field transportation scenarios, solving the problem of poor shock resistance during transportation. At the same time, the folding structure can reduce the storage volume, save transportation space, and adapt to outdoor mobile scenarios.

[0030] For example, such as Figure 1 As shown, a rubber shock-absorbing wheel 6 is installed at each of the bottom corners of the container 2. The wheel axle has a built-in spring shock-absorbing component, and the wheel has a manually operable locking brake mechanism. By operating the brake component, the wheel can be locked and unlocked. During transportation, after unlocking the brake component, the container 2 is pushed, and the shock-absorbing wheel 6 will cushion the bumps caused by the spring component as the road surface undulates. After reaching the destination, the brake component is operated to lock the wheel to prevent the container 2 from sliding. In the fixed use state, keeping the brake locked can prevent the container 2 from shifting due to uneven ground in the wild.

[0031] Shock-absorbing wheels 6 allow the housing 2 to be moved easily without manual handling, greatly reducing the labor intensity of field transportation and solving the problem of inconvenient transportation; the spring shock-absorbing components built into the wheel axles can further weaken the impact of transportation, protect the multimedia module 1 inside the housing, reduce the probability of failure, and supplement the problem of poor shock resistance; in the outdoor teaching and field training of the troops, the equipment can be quickly transferred to different sites, significantly improving deployment flexibility.

[0032] For example, such as Figure 3As shown, multiple mounting through holes 7 are opened in the middle of the side wall of the cabinet 2. Rubber sealing rings are pasted on the hole walls. The HDMI input / output connector 8 of the multimedia module 1 is fixed in the through hole by a buckle, and the end of the connector is flush with the side wall of the cabinet 2 and does not protrude from the outer wall.

[0033] When connecting external devices, insert the external HDMI cable into the HDMI connector inside the through-hole. The rubber sealing ring will cover the gap between the cable and the through-hole. When the HDMI connector is not in use, the connector is hidden inside the through-hole, and the sealing ring can prevent wind and sand from entering the box, avoiding damage to the connector. The combination of the through-hole sealing ring and the retracted connector prevents wind and sand from entering the connector interface, avoiding poor contact and solving the problem of wind and sand affecting equipment use in the field. External devices can be connected without opening the box 2, simplifying the operation process and meeting the needs of rapid signal access in emergency command scenarios, thus improving practicality. At the same time, the connector does not protrude from the outer wall, which can avoid damage from impacts and extend the service life of the equipment.

[0034] For example, such as Figure 4 As shown, multiple elastic protrusions 14 made of rubber are provided on both sides of the inner wall of the mounting base 5. The protrusions are integrally formed with the mounting base 5. A slot is provided at the corresponding position on the side wall of the multimedia module 1, and the edge of the slot is rounded to facilitate the protrusions to be inserted.

[0035] When installing the module, align the multimedia module 1 with the mounting base 5 and press it inwards. The elastic protrusion 14 will deform under pressure. After the module is fully inserted into the mounting base 5, the protrusion will spring back and snap into the slot, thus securing the module. When removing the module, hold both sides of the module and pull outwards. The protrusion will deform under pressure from the slot and then dislodge, allowing the module to be removed. The snap-fit ​​structure between the protrusion and the slot, combined with the elastic shock-absorbing pad, provides double fixation for the module, preventing displacement and collision during transportation due to vibration, thus solving the problem of module displacement caused by transportation vibration. The module can be disassembled and installed without the need for tools, simplifying the maintenance process, meeting the needs of rapid field maintenance by military units, and improving maintenance efficiency. Furthermore, the elastic protrusion 14 is compatible with multimedia modules 1 of different sizes, effectively improving the equipment's versatility.

[0036] For example, such as Figure 1 As shown, the telescopic rod 9 is composed of multiple sleeves, and a hydraulic damping component is provided between the sleeves to prevent excessive extension and retraction. One end of the telescopic rod 9 is hinged to the upper part of the inner wall of the box 2, and the other end is hinged to the middle position of the bottom of the mounting frame 3.

[0037] When the display screen 4 is opened, the mounting frame 3 is flipped upwards, and the telescopic rod 9 will extend synchronously with the rotation of the mounting frame 3. The hydraulic damping component can control the extension speed to prevent the mounting frame 3 from flipping suddenly. When the mounting frame 3 is deflected to the appropriate angle, the telescopic rod 9 extends to the corresponding length to form a stable support. When the display screen 4 is closed, the mounting frame 3 is pressed downwards, and the telescopic rod 9 slowly retracts until the mounting frame 3 is in contact with the top surface of the cabinet 2, and the telescopic rod 9 also retracts to its shortest length.

[0038] Therefore, no manual support or additional fasteners are needed. The telescopic rod 9 can automatically stabilize the angle of the display screen 4, making it suitable for outdoor use scenarios without fixed support and solving the problem of inconvenient support for the display screen 4. The hydraulic damping design can prevent the mounting frame 3 from suddenly falling and injuring people or damaging equipment, meeting the safety requirements of military field operations and improving safety. The length of the telescopic rod 9 can also be adjusted to deflect the display screen 4 to different angles to meet the viewing needs of different numbers of people and adapt to multiple scenarios.

[0039] For example, such as Figure 1 As shown, the display screen 4 is embedded in the mounting frame 3 by a waterproof adhesive strip. A glare-proof shield 10 is hinged to the top of the mounting frame 3. The shield 10 is sized to match the top surface of the mounting frame 3 and can be vertically rotated around the hinge. When rotated to a specific angle, it is secured by a clip on the top of the mounting frame 3. During transportation or storage, the shield 10 is rotated downwards to fit against the mounting frame 3, completely covering the surface of the display screen 4. When used outdoors, the mounting frame 3 is first rotated open, and then the shield 10 is flipped upwards to a fixed angle, at which point the shield 10 forms a "sunshade" at the top of the display screen 4. When used indoors, the shield 10 can be kept closed to prevent dust from falling onto the display screen 4.

[0040] The combination of anti-glare material and top sunshade can reduce the interference of direct sunlight on the display screen 4, improve the image clarity, and adapt to outdoor teaching scenarios, solving the problem of strong light affecting viewing in the wild; during transportation, the shield 10 can isolate friction and collision, prevent the display screen 4 from being scratched, and extend the service life of the display screen 4; and the shield 10 can be opened and closed flexibly to take into account different indoor and outdoor lighting environments, improving the adaptability of the equipment.

[0041] For example, such as Figure 3 As shown, the side wall of the housing 2 is hinged to the position of the mounting through hole 7 by a baffle 11 made of impact-resistant material. The baffle 11 is large enough to cover all the mounting through holes 7. The inner side is pasted with a buffer pad, and the edge is provided with a buckle that can be fixed to the side wall of the housing 2.

[0042] Furthermore, when not using the HDMI connector, flip the baffle 11 downwards to cover the mounting through hole 7, so that the buckle is locked into the slot and the buffer pad will fit against the side wall of the cabinet 2 to seal the through hole; when using the HDMI connector, after unfastening the buckle, flip the baffle 11 upwards to a suitable angle to expose the mounting through hole 7 and insert the external wiring. After use, close the baffle 11 again.

[0043] The double seal of the baffle 11 and the buffer pad can prevent wind, sand and rain from entering the through hole, protect the HDMI connector, avoid short circuits or poor contact, and solve the problem of wind, sand and rain intrusion in the wild; the impact-resistant material of the baffle 11 can prevent the connector from being damaged by external objects, adapt to complex outdoor environments, and improve the durability of the equipment; the baffle 11 can be opened and closed without tools, simplifying the operation process of external devices and adapting to the needs of rapid operation in emergency command.

[0044] For example, such as Figure 1 As shown, multimedia module 1 comprises three independent modules: an industrial control computer, a mixing console, and a signal processing module. Each module uses a rust-proof metal casing with a heat dissipation structure on the side. During teaching or training, the industrial control computer stores teaching videos and training materials and connects to the signal processing module via wires. After external devices are connected to the mixing console, the mixing console adjusts the audio signal before transmitting it to the signal processing module. The signal processing module switches the video signal to display screen 4 and simultaneously transmits the audio signal to external speakers. During emergency command, the signal processing module quickly switches the external device signal, and the mixing console adjusts the volume of the command voice to ensure clear transmission of instructions.

[0045] By integrating core functional modules, there is no need to purchase and debug individual devices separately; they can be used in conjunction with each other out of the box, adapting to the rapid deployment needs of the troops and solving the problem of low deployment efficiency. The industrial control computer meets the content storage requirements, the mixing console adapts to the audio adjustment requirements, and the signal processing module supports the access of multiple devices, covering multiple scenarios such as teaching, training, and emergency command. The modules are independently packaged and have anti-vibration features, which can reduce the interference of the field environment on the equipment, reduce the probability of failure, and improve the stability of the equipment.

[0046] For example, such as Figure 1 As shown, a power socket 12 with overload protection is fixed inside the box 2. The socket is connected to the energy storage component inside the box through a wire. At the same time, the wire extends to the outside of the box 2 to connect to an external power source. The surface of the socket is equipped with a dust cover with a waterproof adhesive strip pasted on the inside.

[0047] When there is no external power source in the field, open the dust cover and insert the power plug of multimedia module 1 into the socket. The energy storage component will power the module. When the energy storage component is low on power, it can be recharged by an external charger. When there is an external power source, connect the external plug to the external power source. The socket will switch to external power supply and charge the energy storage component at the same time. If an overload occurs, the socket will automatically cut off the power for protection.

[0048] The dual power supply mode of energy storage components and external power supply can adapt to the field without power grid, ensuring continuous operation of the equipment and avoiding interruption of teaching or missions, thus solving the problem of limited power supply in the field; the overload protection function can prevent short circuits, and the combination of dust cover and waterproof strip can prevent moisture and dust from entering the socket in the field, reducing the risk of electric shock and improving safety; the energy storage components do not require external cables, which makes it easy for the equipment to move flexibly in the field and further improves deployment flexibility.

[0049] For example, such as Figure 3 As shown, the mounting frame 3 is surrounded by a metal enclosure 13. A waterproof strip is pasted on the inner wall of the enclosure 13. The outer wall of the top surface of the box 2 is provided with a stepped structure. When the mounting frame 3 is closed, the inner side of the enclosure 13 abuts against the step of the box 2, and the waterproof strip is squeezed and deformed to form a seal.

[0050] When storing or transporting, rotate the mounting frame 3 around the hinge so that the enclosure 13 is aligned with the step of the cabinet 2. After pressing the mounting frame 3 down, the waterproof strip is squeezed and adheres to the step, thus sealing the top surface of the cabinet 2. When in use, flip the mounting frame 3 upward, and the enclosure 13 will rotate synchronously with the mounting frame 3 without affecting the unfolding of the display screen 4. After use, close the mounting frame 3 again to restore the sealed state of the cabinet 2.

[0051] The sealing structure of the enclosure 13 and the waterproof strip can prevent wind, sand and rainwater from entering the interior of the box 2, protect the multimedia module 1, and prevent the components from being damaged by moisture and dust accumulation, thus solving the problem of wind, sand and rainwater intrusion in the wild; the metal enclosure 13 can enhance the strength of the mounting frame 3, prevent the mounting frame 3 from deforming and causing the seal to fail, adapt to complex outdoor environments, and improve the durability of the equipment; this sealing structure ensures that the equipment can still be transported normally in rainy and dusty weather, effectively expanding the range of environments in which the equipment can be used.
