Description

Technical Field

[0001] This invention relates to the field of ground support equipment technology for unmanned aerial vehicles (UAVs), specifically to a UAV frame and the UAV itself that is used in conjunction with an air defense shelter. Background Technology

[0002] During ground parking, maintenance, battery replacement, and pre-battle checks, drones require ground support frames to maintain a level position and prevent wing deformation due to tilting forces. Various drone ground supports or parking platforms already exist, such as tripod or quadruped structures, folding supports, and drone lifting platforms mounted in vehicles or container cabins. These devices typically provide basic support and leveling functions, and some integrate folding storage structures to accommodate vehicle-mounted storage and transportation needs. While drone ground supports have seen some application in civilian and some military scenarios, their structural designs are primarily based on conventional, mild environmental conditions, with insufficient consideration given to adaptability to extreme environments.

[0003] In high-altitude areas, the temperature difference between day and night is significant, with nighttime temperatures dropping below -40°C. When operators deploy drones at their sites, they first need to adjust the height of each outrigger to adapt to the uneven ground and level the drone. However, the intense sunlight during the day on the plateau causes surface snow and ice to melt into liquid water, which, driven by wind, easily seeps into the threaded gaps of the outrigger extension joints. At night, the temperature drops sharply, and the meltwater seeping into the threaded gaps quickly freezes, jamming the threads. When operators try to deploy the equipment again the next day, the outrigger extension adjustment points are frozen and cannot rotate. Forcing operation can damage the threads or even render the outriggers unusable. The inability to level the outrigger means the drone cannot be parked properly and subsequent operations cannot be carried out. This repeated freeze-thaw cycle caused by the diurnal temperature variation is a unique technical challenge in high-altitude environments, distinguishing them from other low-temperature regions, and is the most direct predicament encountered by on-site operators. Summary of the Invention

[0004] The purpose of this invention is to provide a drone frame and drone that are compatible with an air defense shelter, in order to solve the problem that in the existing technology, the threads at the extension joint of the outriggers freeze and jam due to the seepage of melt water in the large temperature difference between day and night and repeated freeze-thaw cycles in the plateau environment, which prevents the support from being properly leveled and deployed.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drone frame for use with an air defense shelter, including a frame motherboard;

[0006] Four support legs are respectively located at the four corners of the main frame. Each support leg independently includes an upper support sleeve and a lower telescopic support rod. The top of the upper support sleeve is connected to the bottom of the main frame. The upper part of the lower telescopic support rod extends into the interior of the upper support sleeve and is threaded into the upper support sleeve. The lower end of the lower telescopic support rod extends out from the lower end of the upper support sleeve.

[0007] An adjustable locking mechanism is provided between the upper support sleeve of each leg and the bottom of the frame main board. The adjustable locking mechanism is configured to lock or release the rotational freedom of the upper support sleeve relative to the bottom of the frame main board.

[0008] An antifreeze sealing structure is provided at the lower end of the upper support sleeve and the telescopic engagement point of the lower telescopic support rod. The antifreeze sealing structure includes a double-layer rubber sealing sleeve sleeved outside the telescopic engagement thread groove and low-temperature grease filled inside the thread engagement area.

[0009] A modular loading structure is disposed on the frame motherboard, the modular loading structure including a slide groove disposed on the frame motherboard and at least one functional module detachably mounted on the slide groove.

[0010] Furthermore, the adjusting locking mechanism includes a mounting bracket, an annular gear disc, locking teeth, a linkage plate, and an elastic reset component; the mounting bracket is detachably mounted to the bottom of the main frame via the locking component, the annular gear disc is fixedly mounted to the top of the upper support sleeve, a positioning bearing is provided in the middle of the annular gear disc, a positioning shaft is provided on the vertical support plate at the bottom of the mounting bracket, and the positioning shaft is fixed in the inner ring of the positioning bearing; the annular gear disc has a plurality of tooth grooves distributed circumferentially, and the number of locking teeth is not less than two, each locking tooth corresponding to a tooth groove of the annular gear disc.

[0011] Furthermore, the linkage plate is fixedly connected to one side of the locking tooth, and the elastic reset member is installed on the mounting bracket and applies an elastic force to the locking tooth to tend to engage with the tooth groove; the elastic reset member consists of a movable pin, a reset spring and a pull ring, the movable pin is slidably connected to the mounting bracket, one end of the movable pin is fixed to the side of the linkage plate away from the locking tooth, and the other end is connected to the pull ring, the reset spring is sleeved on the movable pin, one end of the reset spring abuts against the linkage plate, and the other end abuts against the inner side wall of the mounting bracket.

[0012] Furthermore, the double-layer rubber sealing sleeve includes an inner sealing sleeve and an outer dustproof sleeve. The inner sealing sleeve tightly covers the outer periphery of the telescopic threaded groove, and the outer dustproof sleeve is fitted over the inner sealing sleeve. The upper and lower ends of the double-layer rubber sealing sleeve are respectively sealed and fixed to the upper support sleeve and the lower telescopic support rod by clamps to form a sealed protective chamber. The threaded engagement area is located inside the protective chamber.

[0013] Furthermore, the vertical cross-section of the slide is an inverted T-shape, and it is parallel and spaced along the width direction of the main frame. Both ends of the slide penetrate the main frame. The bottom of the functional module is provided with a T-shaped slide seat that matches the slide. The top of the main frame is provided with a spring latch that cooperates with the functional module. The spring latch is a four-bar latch lock mechanism used to fix the functional module.

[0014] Furthermore, the functional module includes at least one of the following: a battery constant temperature preheating chamber, a tool storage box, a remote control support tray, and a quick-release interface for an anti-drone jammer;

[0015] The battery constant temperature preheating chamber includes a chamber body, aerogel insulation cotton disposed in the chamber body interlayer, a PTC constant temperature heating film disposed in the chamber body, a temperature sensor and a temperature control module. The PTC constant temperature heating film is configured to be connected to an external power source through a power interface. The temperature control module controls the PTC constant temperature heating film to maintain the temperature inside the chamber at 5℃~18℃ according to the detection signal of the temperature sensor.

[0016] The tool storage box is a rigid box with internal compartments and a sealing strip at the opening.

[0017] The remote control support includes a base and a tray disposed on the base. The tray is inclinedly disposed on the top of the base. The upper surface of the tray is provided with an anti-slip silicone pad layer. The top of the base is also provided with a device slot.

[0018] A power module is located at the bottom of the frame motherboard, and the power module is electrically connected to the functional module.

[0019] Furthermore, the main frame adopts a bi-fold hinge structure, which includes a damping hinge located in the middle of the main frame. The main frame is divided into a left half frame plate and a right half frame plate by the damping hinge. Locking buckles are symmetrically arranged on both sides of the main frame. When the left half frame plate and the right half frame plate are folded in half, the locking buckles engage and lock with each other.

[0020] Furthermore, the bottom of both the left and right half-frame plates is provided with standard sliders. The size of the standard sliders is configured to match the fixed guide rails inside the air-raid shelter. The main frame plate slides into the fixed guide rails via the standard sliders and is locked and fixed by the shelter straps.

[0021] Furthermore, each outrigger has a connector at the bottom of its lower telescopic support rod, and a support accessory is detachably installed in the connector. The support accessory is an anti-slip rubber pad or a steel ground stake. The anti-slip rubber pad includes a thickened rubber body and a hard steel plate embedded inside the rubber body. The bottom surface of the rubber body has anti-slip texture.

[0022] An unmanned aerial vehicle (UAV) includes a UAV body and a UAV frame with a matching air defense shelter as described above, wherein the UAV body is detachably mounted on the UAV frame.

[0023] Compared with the prior art, the present invention provides a drone frame for a matching air defense shelter and the drone thereof;

[0024] 1. The provided anti-freezing container for UAVs features a double-layered rubber sealing structure at the telescopic joint between the lower end of the upper support sleeve and the lower telescopic support rod. This encloses the entire threaded engagement area within a sealed protective chamber, effectively isolating the threaded surface from external meltwater, moisture, and sand. Simultaneously, low-temperature grease filled within the threaded engagement area ensures lubrication of the threaded pair at -40°C, preventing the threads from freezing and jamming under the repeated freeze-thaw cycles of daytime meltwater infiltration and nighttime freezing at high altitudes. Operators can easily rotate and adjust the outrigger height to level the aircraft, solving the problem of existing technologies where the support frame cannot be properly leveled and deployed under repeated freeze-thaw conditions at high altitudes. Furthermore, no additional de-icing or lubrication is required for field use. The anti-freezing sealing structure (located at the lower part of the outriggers) and the adjusting locking mechanism (located at the bottom of the frame mainboard) are arranged separately along the outrigger axis. The adjusting locking mechanism is positioned higher and away from areas of ground ice and snow accumulation, reducing the risk of ice and snow directly contacting the locking mechanism. Both operate independently without interference, resulting in a clear and reliable structure.

[0025] 2. The four legs of the drone frame are independently adjustable. Combined with the height markings on the sides of the legs and the bubble level in the center of the frame's mainboard, a single person can quickly level the drone on undulating ground, preventing wing deformation due to tilting during parking or maintenance. Each functional module is detachably mounted to the mainboard via sliding grooves. Operators can choose to equip it with a battery preheating compartment, tool storage box, remote control support, or quick-release interface for anti-drone jammers, achieving multiple uses and reducing the amount of scattered equipment carried at the site. The mainboard uses a bi-fold hinge structure, maintaining its folded state with locking buckles. The standard slider at the bottom can be used with the internal fixed rails of the air defense container for quick storage and fixation. When folded, its compact size does not occupy internal storage space, allowing a single person to quickly deploy or retract it, meeting the rapid deployment and withdrawal requirements of air defense operations.

Detailed Implementation

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] Example 1:

[0038] like Figures 1 to 3 As shown, the present invention provides a drone frame for an air defense shelter, including a frame main board 1, four legs 2, an adjustment and locking mechanism, an anti-freeze sealing structure, a modular loading structure, a folding locking structure, and a shelter fixing structure.

[0039] The main frame 1 is a rectangular flat panel structure, made of aluminum alloy through a hollowing process, and weighs 3.2 kg. A damping hinge 23 is located in the middle of the main frame 1, dividing it into a left half-frame plate 101 and a right half-frame plate 102. The damping hinge 23 is a metal damping pivot. Mounting positions are located at the four corners of the main frame 1 for connecting the four support legs 2.

[0040] Four support legs 2 are respectively located at the four corners of the main frame 1. Each support leg 2 independently includes an upper support sleeve 201 and a lower telescopic support rod 202. The top of the upper support sleeve 201 is connected to the bottom of the main frame 1. The upper part of the lower telescopic support rod 202 extends into the interior of the upper support sleeve 201. The outer wall of the lower telescopic support rod 202 has external threads, and the inner wall of the upper support sleeve 201 has matching internal threads. The lower telescopic support rod 202 and the upper support sleeve 201 are connected by threads to achieve telescopic movement. The lower end of the lower telescopic support rod 202 extends from the lower end of the upper support sleeve 201. The telescopic stroke of the lower telescopic support rod 202 is 0-220mm. The upper support sleeve 201 and the lower telescopic support rod 202 are made of stainless steel. Millimeter-level height markings are engraved on the side of each support leg 2, and a bubble level is embedded in the center of the main frame 1. The four legs 2 are slightly tilted outward relative to the main frame 1, unfolding in a figure-eight shape, with an tilt angle of 5° to 15°.

[0041] An adjusting locking mechanism is located between the upper support sleeve 201 of each support leg 2 and the bottom of the main frame 1. The adjusting locking mechanism is configured to lock or release the rotational freedom of the upper support sleeve 201 relative to the bottom of the main frame 1. The adjusting locking mechanism includes a mounting bracket 4, an annular gear disc 5, locking teeth 6, a linkage plate 7, and an elastic reset component. The mounting bracket 4 is detachably mounted to the bottom of the main frame 1 via a locking component 8, which is a bolt. The annular gear disc 5 is fixedly mounted on the top of the upper support sleeve 201 and rotates with the upper support sleeve 201. A positioning bearing 9 is located in the middle of the annular gear disc 5, and a positioning shaft 10 is located on the vertical support plate at the bottom of the mounting bracket 4, fixed in the inner ring of the positioning bearing 9. Several tooth grooves 501 are distributed circumferentially on the annular gear disc 5. There are two locking teeth 6, each corresponding to a tooth groove 501 on the annular gear disc 5.

[0042] The linkage plate 7 is fixedly connected to one side of the locking tooth 6. An elastic reset element is mounted on the mounting bracket 4 and applies an elastic force to the locking tooth 6, tending to engage with the tooth groove 501. The elastic reset element consists of a movable pin 11, a return spring 12, and a pull ring 13. The movable pin 11 is slidably connected to the mounting bracket 4, with one end fixed to the side of the linkage plate 7 away from the locking tooth 6, and the other end connected to the pull ring 13. The return spring 12 is sleeved on the movable pin 11, with one end abutting against the linkage plate 7 and the other end abutting against the inner wall of the mounting bracket 4. The annular gear disc 5 is made of 45# steel, heat-treated, and then machined to have a tooth surface hardness of HRC45~50. The locking tooth 6 is made of the same material and its surface is treated for wear resistance.

[0043] With the above structure, in its natural state, the return spring 12 applies an elastic force to the linkage plate 7, causing the linkage plate 7 to engage the locking teeth 6 into the tooth groove 501 of the annular toothed disc 5. This locks the rotational freedom of the upper support sleeve 201 relative to the bottom of the frame main plate 1, and fixes the height of the support leg 2. When the operator pulls the pull ring 13, the movable pin 11 causes the linkage plate 7 to move against the elastic force of the return spring 12, disengaging the locking teeth 6 from the tooth groove 501 and releasing the rotational freedom of the upper support sleeve 201. At this time, the operator rotates the upper support sleeve 201, and due to the threaded engagement between the lower telescopic support rod 202 and the upper support sleeve 201, the lower telescopic support rod 202 extends or retracts axially.

[0044] The operator adjusts each outrigger 2 to the required height using the height markings on the side of the outrigger 2 and the bubble level in the center of the main frame 1. Once adjusted, the operator releases the pull ring 13, and the locking teeth 6 automatically engage with the corresponding groove 501 of the annular toothed disc 5 under the elastic force of the return spring 12, locking the rotational freedom of the upper support sleeve 201 again, thus fixing the height of the outrigger 2. This adjustment and locking mechanism is a mechanical hard-locking method with strong load-bearing capacity, ensuring that the height of the outrigger 2 will not automatically sink or shift during high-wind conditions or vehicle transport. The four outriggers 2 can be adjusted completely independently without interference. Because the adjustment and locking mechanism is located at the bottom of the main frame 1, i.e., at the top of the outrigger 2, the operator can complete the adjustment and locking operation without bending over to the middle of the outrigger 2, reducing the difficulty of operation in cold, high-altitude environments.

[0045] Example 2:

[0046] like Figure 1 and Figure 4 As shown, the antifreeze sealing structure is located at the lower end of the upper support sleeve 201 and the telescopic engagement point of the lower telescopic support rod 202. The antifreeze sealing structure includes a double-layer rubber sealing sleeve fitted outside the telescopic engagement threaded groove and low-temperature lubricating grease filled inside the threaded engagement area.

[0047] The double-layer rubber sealing sleeve includes an inner sealing sleeve 14 and an outer dustproof sleeve 15. The inner sealing sleeve 14 tightly covers the outer periphery of the expansion joint threaded groove, and the outer dustproof sleeve 15 is fitted over the inner sealing sleeve 14. The upper end of the double-layer rubber sealing sleeve is sealed and fixed to the outer wall of the upper support sleeve 201 by a clamp, and the lower end is sealed and fixed to the outer wall of the lower telescopic support rod 202 by a clamp, forming a sealed protective chamber. The threaded engagement area is located within the protective chamber. The inner sealing sleeve 14 and the outer dustproof sleeve 15 are made of silicone rubber. The clamp is made of stainless steel strip and is tightened by screws. Low-temperature grease is filled between the threads in the threaded engagement area. The low-temperature grease is a fully synthetic hydrocarbon-based grease with an operating temperature range of -45℃ to +120℃.

[0048] Through the above structure, the double-layer rubber sealing sleeve encloses the entire threaded engagement area within a sealed protective chamber. When meltwater from ice and snow in the external environment flows along the outer wall of the lower telescopic support rod 202 or the upper support sleeve 201, the outer dust cover 15 forms the first barrier against the meltwater. Because the outer dust cover 15 is sealed and fixed to the upper support sleeve 201 and the lower telescopic support rod 202 by clamps, meltwater cannot enter the interior of the sealing sleeve. Even if a small amount of water vapor attempts to move towards the telescopic fit gap under the action of pressure difference or capillary effect, the inner sealing sleeve 14 forms the second barrier, preventing water vapor from entering the threaded engagement area. At the same time, the low-temperature grease filled between the thread teeth further fills the tiny gaps in the threaded pair, ensuring that even if water vapor breaks through the sealing sleeve, it cannot directly contact the threaded metal surface.

[0049] At -40℃, the low-temperature grease will not solidify or thicken, and the threaded pair can still rotate smoothly. The double-layer structure of the inner sealing sleeve 14 and the outer dust cover 15 in the double-layer rubber sealing sleeve provides redundant sealing protection. When the outer dust cover 15 experiences slight wear during long-term use, the inner sealing sleeve 14 can still maintain the sealing effect. This antifreeze sealing structure ensures that the expansion joint threads will not freeze and jam due to ice formation, nor will they rust and corrode due to moisture intrusion, in the harsh environment of large temperature differences between day and night and repeated freeze-thaw cycles of ice and snow in the plateau region. No additional de-icing or lubrication is required during field use. At the same time, the antifreeze sealing structure is located at the lower end of the outrigger 2 (at the expansion joint outlet), and the adjusting locking mechanism is located at the bottom of the frame main board 1 (at the upper end of the outrigger 2). The two are arranged vertically and vertically separately along the axial direction of the outrigger 2, working independently and without interference. The adjusting locking mechanism is positioned high and far away from the ground ice and snow accumulation area, reducing the risk of ice and snow directly contacting the locking mechanism.

[0050] Example 3:

[0051] like Figure 1 , Figure 5 and Figure 7 As shown, the modular loading structure is mounted on the frame motherboard 1. The modular loading structure includes a slide 3 mounted on the frame motherboard 1 and functional modules that are detachably mounted on the slide 3.

[0052] The slide rails 3 are located on the left and right main beams of the frame main board 1. The vertical cross-section of the slide rails 3 is an inverted T-shape, and they are parallel and spaced along the width direction of the frame main board 1. Both ends of the slide rails 3 penetrate the frame main board 1. The slide rails 3 are integrally formed with the frame main board 1 from aluminum alloy. The bottom of the functional module is provided with a T-shaped slide block 16 that matches the slide rail 3. The top of the frame main board 1 is provided with a spring latch 17 that cooperates with the functional module. The spring latch 17 is a four-bar linkage latch lock mechanism used to fix the functional module. The T-shaped slide block 16 is provided with a snap-fit ​​structure that cooperates with the spring latch 17. When the T-shaped slide block 16 slides along the slide rail 3 to the predetermined position, the spring latch 17 engages and locks with the snap-fit ​​structure on the T-shaped slide block 16. During disassembly, simply open the spring latch 17 to slide the functional module out along the slide rail 3. The entire disassembly and assembly process requires no tools.

[0053] The functional modules include a battery constant temperature preheating compartment 18, a tool storage box 19, a remote control support tray 20, and a quick-release interface for an anti-drone jammer 21. Operators can choose to install at least one of the above functional modules according to mission requirements.

[0054] The battery constant temperature preheating chamber 18 includes a chamber body 1801, aerogel insulation cotton disposed within the interlayer of the chamber body 1801, a PTC constant temperature heating film 1802 disposed within the chamber body 1801, a temperature sensor 1803, and a temperature control module 1804. The PTC constant temperature heating film 1802 has a Curie temperature of 20℃±3℃, a rated voltage of 24V, and a rated power of 30~50W. The PTC constant temperature heating film 1802 is configured to connect to an external power source via a power interface. The temperature sensor 1803 is disposed inside the chamber body 1801. The temperature control module 1804 controls the PTC constant temperature heating film 1802 to maintain the internal temperature of the chamber at 5℃~18℃ based on the detection signal from the temperature sensor 1803. The top of the chamber body 1801 has a flip cover. The chamber body 1801 can simultaneously hold two drone lithium batteries. In high-altitude and low-temperature environments, the battery can be preheated to a suitable operating temperature in the battery constant temperature preheating chamber 18 before being taken out, installed on the drone, and taken off, without having to wait for the battery to heat up naturally in the field.

[0055] The tool storage box 19 has a rigid body and internal compartments for storing lens cleaning cloths, fastening screws, small repair wrenches, and photoelectric lens protective caps. A sealing strip is provided at the box opening; when the lid is closed, the sealing strip adheres to the edge of the box to prevent dust from entering.

[0056] The remote control support tray 20 includes a base 2001 and a tray 2002 mounted on the base 2001. The tray 2002 is inclined on the top of the base 2001, and its upper surface is provided with an anti-slip silicone pad 2003. The top of the base 2001 also has a device slot 2004 for placing a mobile phone or tablet. When the remote control is placed on the tray 2002, the anti-slip silicone pad 2003 prevents the remote control from sliding. Operators can view the battlefield situation map by placing the device in the device slot 2004.

[0057] The quick-install interface 21 for the anti-drone jammer includes a mounting base plate on the T-shaped slide 16 and a quick-install locking structure on the mounting base plate. The quick-install locking structure is adapted to connect with the bottom interface of the anti-drone jammer. When the site faces a drone threat, the operator can install the anti-drone jammer onto the frame motherboard 1 through the quick-install interface 21.

[0058] A power module 22 is located at the bottom of the mainboard 1, and the power module 22 is electrically connected to the functional modules. The power module 22 is a rechargeable battery pack with a rated voltage of 24V. When the functional module is the battery constant temperature preheating chamber 18, the power module 22 supplies power to the PTC constant temperature heating film 1802; when the functional module is the anti-drone jammer quick-release interface 21, the power module 22 supplies power to the anti-drone jammer installed on it.

[0059] With the above structure, operators can select different functional modules according to mission requirements. Each functional module is slidably installed along the slide groove 3 via T-shaped slide base 16 and fixed by spring buckles 17, allowing for quick assembly, disassembly, and replacement without tools. All functional modules are integrated onto the frame motherboard 1, reducing the amount of scattered equipment carried at the site and lowering the risk of equipment loss. The battery constant temperature preheating chamber 18 solves the problem of battery capacity decay at low temperatures in high altitudes, eliminating the need for preheating time in the field. The tool storage box 19 provides centralized storage for all maintenance parts. The remote control support 20 frees the operator's hands, allowing a single person to complete pre-battle inspections of the UAV. The quick-install interface 21 for the anti-UAV jammer allows the frame to serve as a platform for mounting the anti-UAV jammer, making it multi-functional and improving the overall combat effectiveness of the equipment.

[0060] Example 4:

[0061] like Figure 1 and Figure 6 As shown, each outrigger 2 has a connector 26 at the bottom of its lower telescopic support rod 202. A support accessory 27 is detachably installed inside the connector 26. The support accessory 27 is either a non-slip rubber pad or a steel ground stake. The connector 26 and the support accessory 27 are quickly connected via a snap-fit ​​mechanism.

[0062] The anti-slip rubber feet consist of a thickened rubber body and a rigid steel plate embedded inside the rubber body. The bottom surface of the rubber body has anti-slip patterns, which are deep diamond-shaped patterns. When the frame is used on hardened roads, Gobi gravel surfaces, or the interior of a container, operators can install the anti-slip rubber feet. The anti-slip patterns increase friction with the ground, preventing the frame from slipping and shifting.

[0063] The steel ground stake consists of a tapered stake body and a snap-fit ​​structure at the tail end of the stake body, which is compatible with the insertion interface 26. The steel ground stake is made of 40Cr alloy steel, with the tip of the tapered stake having a hardness of HRC50 or higher and a length of 12cm. When the frame is used on frozen soil or soft slopes in high-altitude areas, operators select to install the steel ground stake, driving the tapered stake body into the frozen soil or soil layer. The steel ground stake forms an anchoring force with the ground, and together with the four support legs 2, fixes the frame to the ground, resisting strong winds and preventing the frame from slipping and the drone from tipping over.

[0064] The replacement of the two types of support accessories 27 requires no tools. Operators can complete the uniform replacement of the support accessories 27 for all four outriggers 2 in a short time, based on the actual terrain conditions. The anti-slip rubber foot pads are used when the frame is retracted into the container to cushion the vibrations during vehicle transportation and prevent the outriggers 2 from hitting the inner wall of the container.

[0065] Example 5:

[0066] like Figure 1 , Figure 5 and Figure 6 As shown, the main frame 1 adopts a bi-fold hinge structure. The bi-fold hinge structure includes a damping hinge 23 located in the middle of the main frame 1. The main frame 1 is divided into a left half frame plate 101 and a right half frame plate 102 by the damping hinge 23. Locking buckles 24 are symmetrically arranged on both sides of the main frame 1. When the left half frame plate 101 and the right half frame plate 102 are folded in half, the locking buckles 24 engage and lock together.

[0067] Both the left half-frame plate 101 and the right half-frame plate 102 have standard sliders 25 at their bottoms. The dimensions of the standard sliders 25 are configured to fit the fixed guide rails inside the air-raid shelter. The main frame plate 1 slides into the fixed guide rails via the standard sliders 25 and is locked in place by the shelter's straps. There are two standard sliders 25, symmetrically arranged at the bottoms of the left half-frame plate 101 and the right half-frame plate 102. The standard sliders 25 are fitted with the fixed guide rails with a clearance fit.

[0068] When the mission is completed and the equipment needs to be withdrawn, the operator first removes each functional module from the slide rail 3 and stores it separately. Then, the support accessory 27 is removed from the connector 26 and stored. The operator holds the outer edges of the left half-frame plate 101 and the right half-frame plate 102 respectively and folds them inward around the damping hinge 23 in the middle. The damping hinge 23 provides damping torque, making the folding process smooth and controllable. When the left half-frame plate 101 and the right half-frame plate 102 are completely folded and overlapped, the locking buckle 24 automatically engages, locking the folded state. At this time, the frame has a flat plate structure, and the overall thickness after folding is 12cm.

[0069] The operator aligns the standard slider 25 on the back of the folded frame main board 1 with the entrance end of the fixed guide rail on the side wall of the container, pushes the frame main board 1 in along the guide rail, and slides the standard slider 25 along the fixed guide rail to the predetermined position. Then, the operator uses the straps provided with the container to pass through the fixing holes on the frame main board 1 and locks the frame main board 1 to the side wall of the container.

[0070] With the above structure, the frame has a small folded size, which does not occupy the internal storage space of the container. The standard slider 25 built into the container works with the fixed guide rail to achieve quick storage and fixation, and the frame will not shake or collide with other equipment during long-distance off-road transportation. The folding and unfolding operation can be completed by a single person without auxiliary tools, and the dismantling time is short, which is suitable for the mobility requirements of rapid attack and withdrawal in air defense operations. At the same time, the frame main board 1 adopts an aluminum alloy hollow structure, and the whole machine weighs 3.2kg, which can be lifted and carried by a single person with one hand, reducing the physical exertion of operators during high-altitude marches and transport.

[0071] Example 6:

[0072] like Figure 1 As shown, the present invention also provides a drone, including a drone body and a drone frame with a matching air defense container as described in any of the above embodiments. The drone body is detachably mounted on the drone frame.

[0073] When deployed, the drone frame supports the drone body in a horizontal position, facilitating parking, maintenance, and battery replacement. When takeoff is required, the operator removes the preheated battery from the battery preheating compartment 18, installs it on the drone body, and it is ready for takeoff. When relocation is needed, the drone body is removed from the frame for separate storage, while the frame is folded and stored inside the container.

[0074] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
