[0029] The fuselage, canard assembly, and tail assembly are interconnected internally for the layout of the electronic control module, energy module, payload module, and related wiring, facilitating power connection and signal transmission. This is a commonly used structure in the field and will not be elaborated further.

[0030] Furthermore, such as Figures 2 to 5As shown, the first wing 410 includes a first support plate 600 and a first locking structure 700; the two end faces of the first support plate 600 are provided with first slots 610, the positions of the first slots 610 correspond to the positions of the first latch head 510 and the second latch head 520, and their shapes are adapted; the first support plate 600 is provided with a first chamber 620, the first chamber includes a through hole communicating with the first slot, the first locking structure 700 is installed in the first chamber 620, and the locking tongue 7231 of the first locking structure 700 extends movably into the first slot 610; the first support plate 600 is adapted to be engaged between the corresponding first latch head 510 and second latch head 520 through the first slot 610, and is locked by the first locking structure 700; the first The locking structure can be adjusted to release the locking of the first and second locking heads; the second wing includes a second support plate and a second locking structure; the two ends of the second support plate are provided with second slots, the structure of the second slots is the same as that of the first slots and their positions correspond; the second support plate is provided with a second chamber, the structure of the second chamber is the same as that of the first chamber; the second locking structure is the same as the first locking structure and is adapted to be installed in the second chamber; with the above structural design, the locking heads and slots engage to provide initial connection; and the locking is achieved by inserting the locking tongue into the corresponding locking heads, so that the locking heads cannot be disengaged from the slots, preventing the side wing structure from detaching or separating, and effectively maintaining the stability of the overall structure.

[0031] Furthermore, two second clips are installed on each of the first and second wing plates, and multiple first clips are installed on the side walls of the fuselage. The two ends of the first support plate are provided with a corresponding number of first slots, and their positions are corresponding. The two ends of the second support plate are provided with a corresponding number of second slots, and their positions are corresponding. The multi-point connection and cooperation further strengthens the overall structural strength, prevents the side wing device from detaching from the fuselage, and prevents the side wing device itself from loosening and detaching.

[0032] Furthermore, such as Figure 7 As shown, the first latch 510 includes a first support block 513. A first latch 511 is fixedly provided at the center of the end face of the first support block 513, and a second latch 512 is fixedly provided at the end of the first latch 511. The diameter of the second latch 512 is larger than the diameter of the first latch 511. A first insertion hole 514 is provided at the center of the end face of the second latch 512. The shape of the first insertion hole 514 is adapted to the shape of the latch tongue 7231. The structure of the second latch 520 is the same as that of the first latch 510. Figure 4As shown, the first slot 610 includes a first recess 611, the width of which is adapted to the diameter of the second locking post 512, and both ends of the first recess are arc-shaped structures; a retaining ring 612 is fixedly provided at the opening of the first recess 611, the retaining ring is U-shaped, the inner ring width of the retaining ring 612 is adapted to the diameter of the first locking post 511; the thickness of the first locking post is adapted to the thickness of the retaining ring, and the thickness of the second locking post is adapted to the distance between the bottom of the first recess and the inner wall of the retaining ring; and the center of the bent part of the retaining ring corresponds to the center of the perforation; under this cooperation, the locking head and the slot form an effective locking engagement, and the second locking post can only be disengaged from the slot when and only when the second locking post is aligned with the end of the recess away from the retaining ring; that is to say, even in the unlocked state, the side wing device needs to be moved along the corresponding trajectory before it can be disengaged, effectively preventing the side wing device from disengaging from the fuselage, and also preventing separation between the wing and the wingplate;

[0033] The edges of the second locking pin and the retaining ring are chamfered to facilitate the smooth insertion of the second locking pin into the first locking slot and make it easy to assemble and disassemble. The edges of the port of the first insertion hole and the insertion end of the locking tongue are chamfered to facilitate the insertion of the locking tongue into the first insertion hole and achieve locking.

[0034] Furthermore, such as Figure 4 As shown, the first chamber 620 includes a second recess 621, which is located on the top surface of the first support plate and extends along the length of the first support plate. First sliding grooves 622 are provided on both sides of the bottom surface of the second recess 621, with both ends extending to the end faces of the first recess. A through hole is provided on the end face of the first sliding groove, comprising a first hole segment 623 and a second hole segment 624 that communicate with each other. The diameter of the first hole segment 623 is larger than the diameter of the second hole segment 624, and the other end of the second hole segment 624 communicates with the first slot 610. The first locking structure 700 includes an unlocking element 710 and two locking components 720, which are symmetrically arranged. At both ends of the first sink groove; the locking assembly includes two locking rods, which are movably installed at the through holes. The locking tongue of the locking rod extends into the first slot through the second hole section; the other end of the locking rod is linked with the unlocking component. By adjusting the unlocking component, the locking rod is moved towards the center of the second sink groove, so that the locking tongue is retracted into the second hole section; the provided second sink groove, first sliding groove, first hole section and second hole section can provide corresponding installation space for the locking assembly, limit the movement trajectory of the locking assembly, and enable it to connect and cooperate with the corresponding locking head; in addition, the use of the unlocking component can simultaneously adjust and drive the two locking assemblies, which can make the wing detach from the fuselage and wingplate at the same time, making the operation more convenient;

[0035] Furthermore, the bottom of the first groove has an arc-shaped surface structure; such as Figure 5 , Figure 6As shown, the locking assembly 720 includes a bracket 721, a limiting bracket 722, two locking rods 723, and two springs 724. The locking rod 723 includes a locking tongue 7231, with a slider 7232 fixedly mounted on its end face. The diameter of the slider is larger than the diameter of the locking tongue, and the diameter of the slider 7232 is adapted to the diameter of the first groove 622 and the first hole section 623. A rod 7233 is fixedly mounted at the center of the end face of the slider 7232 away from the locking tongue, and a locking block 7234 is fixedly mounted at the end of the rod 7233. The springs... Spring 724 is sleeved on rod 7233 and is movably disposed in the first hole 623 to provide outward elastic force for the locking tongue. Limit bracket 722 is installed at the end of the second recess 621 to prevent spring 724 from disengaging from the first hole 623. Sleeves 7211 are fixed at the bottom of both ends of bracket 721, and locking blocks are inserted into the sleeves and fixed by screws. The top of bracket 721 is linked with unlocking component 710. By adjusting unlocking component, the locking rod is moved in the direction of unlocking component to achieve unlocking.

[0036] The overall structure adopts an assembly-type design, which facilitates the processing and production of each structural component and makes it easy to disassemble and replace parts. The slider can slide closely against the inner wall of the first groove and the first hole section, and as a component that contacts the end of the spring and receives force, it provides the locking rod with a spring force to push it towards the slot through the spring, maintaining the extended state of the locking tongue. This keeps it in a locked state when the unlocking part is not subjected to external force, effectively preventing it from loosening.

[0037] It should be noted that after a locking rod is inserted and installed in place, the distance between the end face of the locking block and the other end face of the second sinker should not be less than the length of the locking rod, leaving sufficient installation space to prevent interference problems during the installation of the locking rod.

[0038] Furthermore, a bearing 730 is installed at the center of the bottom of the second sink 621; a pin 711 is fixedly provided at the center of the bottom surface of the unlocking component 710, and the pin is installed at the bearing; a threaded hole is provided on the top surface of the bracket 721, and a bolt 725 is installed at the threaded hole; a pair of arc-shaped holes 712 are provided on the unlocking component 710, and the bolt 725 is movably inserted through the arc-shaped holes 712; by rotating the unlocking component, the two brackets are driven to move towards each other, so that the lock tongue is retracted into the second hole section; wherein, the unlocking component cooperates with the bolt through the arc-shaped hole, and when the unlocking component rotates, it can convert the rotational force into a force that drives the two locking components to move synchronously towards each other, dragging the lock tongue back into the second hole section, thereby realizing the unlocking action;

[0039] Furthermore, a cover is fitted at the opening of the second sinking tank. The cover has a through hole corresponding to the unlocking component. A limiting ring is provided at the lower end of the through hole. The inner diameter of the limiting ring is matched with the diameter of the unlocking component. The cover blocks the opening of the second sinking tank to maintain the overall fit and prevent excessive impact on flight.

[0040] Furthermore, a handle is fixedly provided on the top surface of the unlocking component, providing a gripping area for easy adjustment of the unlocking component.

[0041] Furthermore, such as Figures 4 to 6 As shown, the bottom surfaces of both ends of the second sink 621 are provided with clamping grooves 625; the limiting frame 722 is a plate-shaped structure, and the bottom of both ends of the limiting frame 722 are provided with corresponding slots 7221 for avoiding the rod. The top of the slot is an arc-shaped structure with a diameter that matches the diameter of the rod; the thickness of the limiting frame matches the width of the clamping groove. The limiting frame 722 is placed in the clamping groove 625 and fixed to the end face of the second sink 621 by screws; the detachable structure facilitates the installation and layout of the overall structure, effectively prevents the spring from detaching from the first hole section, and can also provide the required support force for the spring and provide an outward pushing force for the locking rod.

[0042] Furthermore, such as Figure 2 As shown, a first hook 431 is fixedly provided at the end of the first wing plate 430 near the end of the second wing plate; a second hook 441 is fixedly provided at the end of the second wing plate 440 near the end of the first wing plate; the second hook 441 and the first hook 431 are hooked and engaged with each other; the sidewalls of the first wing plate and the second wing plate that are close to each other are connected by a first fastener; the first wing plate and the second wing plate are separate structures, which can facilitate the assembly and disassembly of the first wing plate and the second wing plate and avoid interference problems between the first wing plate and the second wing plate; in addition, the two adopt the hooking and fastening connection method, so that the two are effectively connected and cooperated, effectively strengthening the overall connection strength and structural strength.
