Specific Embodiments

[0028] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0029] Such as Figure 1 、 Figure 2As shown in the figure, a foldable three-body floating platform structure for an amphibious UAV is disclosed in a specific embodiment of the present invention, which includes a first floating platform 100 and two second floating platforms 200 arranged on both sides of the first floating platform 100; a booster is installed at the rear end of the first floating platform; a first support frame 300 is installed on the top surface of the first floating platform 100, and a second support frame 400 is installed on the top surface of the second floating platform 200. The second support frame extends towards the first floating platform and passes through the outside of the second floating platform. The two second support frames 400 are respectively rotationally connected and matched with both sides of the first support frame 300; locking mechanisms 500 are installed on both sides of the first support frame 300 for locking the second support frames 400 placed in the horizontal and vertical positions; the second floating platform 200 includes a support body 210 and air bags 220 installed at both ends of the support body 210. When the air bags are adjusted to extend out of the support body, the exposed parts of the air bags expand into a boat head-like structure and are connected to the end face of the support body; the air bags can be adjusted to deflate the exposed parts and retract them into the support body.

[0030] The above-mentioned foldable three-body floating platform structure for an amphibious UAV enables the second floating platform to have the functions of folding and unfolding. It can be unfolded during use to provide a large range of support and achieve stable navigation and movement; it can also be folded during transportation, the overall structure is tightened, reducing the occupation of external space and facilitating transfer and transportation; and a locking mechanism is used to lock the rotating parts of the first support frame and the second support frame. It can be unlocked by adjusting the locking mechanism, and then the placement position of the second support frame can be adjusted, which is convenient for use and operation.

[0031] In addition, the two ends of the second floating platform are of air bag structure, enabling the second floating platform to have a secondary adjustment function. It can be inflated and unfolded during use to expand the support range, and deflated during storage to reduce the volume, occupying less space and facilitating transfer and transportation, further enhancing the foldable function.

[0032] Furthermore, as Figures 3 to 5As shown in the figure, the second floating platform 200 includes a support body 210, two air bags 220, and a pushing mechanism 230; a receiving cavity 211 is provided in the middle of the support body 210, and receiving cavities 212 are provided on both end faces of the support body 210. The receiving cavity 212 communicates with the receiving cavity 211 through a first through hole 213; the air bag 220 includes a first bladder, a second bladder, and a third bladder connected in sequence; the two air bags are respectively installed at both ends of the receiving cavity. The first bladder is arranged at the receiving cavity 211, the second bladder is arranged at the first through hole 213, and the third bladder is arranged at the receiving cavity 212; the pushing mechanism 230 is installed in the middle of the receiving cavity 211, and two pushing plates 231 are arranged on the pushing mechanism 230. The two pushing plates can be adjusted to push and move towards both ends of the receiving cavity; the air bag is in an under-inflated and deflated state. When the pushing plate is pushed towards the end of the receiving cavity, the first bladder can be squeezed, so that the second bladder and the third bladder are inflated and expanded, and the third bladder protrudes outwards in a boat-head shape and is connected to the end face of the support body;

[0033] When the pushing plate moves towards the center of the receiving cavity, the squeezing and occupying of the first bladder is released. Squeezing the third bladder can cause the gas to flow to the second bladder and the first bladder, and the third bladder can be retracted into the receiving cavity;

[0034] This structural design can use the under-inflated air bag as the basis for adjustment and transformation, and limit the flow direction of the gas inside the air bag by squeezing the air bag through the pushing mechanism. Thus, when it needs to be deployed, the third bladder will be inflated and expanded, and will present a boat-head-shaped contour, connecting to the end of the support body, making the overall second floating platform present a boat-shaped structure with both ends narrowed. This can not only increase the overall buoyancy but also reduce the resistance of water surface navigation; when the pushing mechanism retracts the pushing plate and releases the squeezing of the air bag, the air bag returns to the deflated state. When further retracting, the third bladder part can be manually squeezed to push the gas towards the second bladder and the first bladder part, so that the third bladder deflates to a state where it can be retracted into the receiving cavity, thus realizing retraction and reduction, and the structure is more compact;

[0035] Furthermore, a second cover plate 250 is provided outside the opening of the receiving cavity 212. The top of the second cover plate 250 is connected to the top surface of the end of the support body 210 through a hinge. Locking knobs 251 are installed on both sides of the second cover plate 250. Threaded holes are correspondingly provided on the end face of the support body. The second cover plate can be fixed to the end face of the support body through the locking knobs to block the port of the receiving cavity; the third bladder received in the receiving cavity is protected and blocked by the second cover plate to prevent it from falling out and detaching;

[0036] Furthermore, the inflation port of the air bag is arranged at the first bladder part, and the air bag is not inflated when installed. After it is installed in place, a preset amount of gas is injected into it to meet the requirements of adjustable transformation.

[0037] Further, a first cover plate 240 is provided on the outer side of the top of the accommodation cavity 211. The first cover plate is fixed to the top surface of the support body by bolts to block the top opening of the accommodation cavity. The adjusting rod of the top pushing mechanism movably penetrates through the middle of the first cover plate and extends outwards for adjustment.

[0038] Further, as Figure 5 shown, the top pushing mechanism 230 includes a frame 232, an adjusting rod 233, two push plates 231, and two chain-operated window openers 234. The frame 232 is fixedly installed in the middle of the accommodation cavity 211 by bolts. The adjusting rod 233 is installed through the middle of the frame 232 through bearings. The two chain-operated window openers 234 are respectively installed in the middle of both sides of the frame 232. The end of the chain of the chain-operated window opener 234 is connected to the center of the push plate 231 through a U-shaped piece. The input shafts of the two chain-operated window openers 234 and the adjusting rod 233 are meshed and driven through a gear set 235. By rotating the adjusting rod, the telescopic movement of the chain of the chain-operated window opener can be driven, which is used to drive the push plate to perform an outward pushing action and a retracting action. By using the chain-operated window opener as a structural component for telescopic movement, a larger top pushing stroke can be provided to effectively squeeze the airbag, so that the third airbag can be quickly inflated and expanded to the required size. When retraction is required, the support chain is retracted into the chain box, which will not overly occupy the internal space and provides enough space for the back movement of the first bladder, naturally facilitating the third airbag to be received in the storage cavity.

[0039] Further, a first round hole is provided on the first cover plate corresponding to the adjusting rod. A sealing ring is provided on the inner wall of the first round hole. The adjusting rod sealingly and movably penetrates through the first round hole and extends out of the first cover plate. A rhombic block is fixedly provided at the top end of the adjusting rod, so that external tools such as a wrench and an electric wrench can be sleeved with it for easy rotation adjustment.

[0040] It should be noted that the manually adjustable chain-operated window opener is a common window opener, and the U-shaped piece is also a connecting component used in combination with it. Both can be purchased and used on the market, and the specific structure will not be elaborated.

[0041] Further, bayonets are provided on both sides of the push plate. Corresponding guide strips are provided on the inner wall of the accommodation cavity. The shape of the guide strip is adapted to the shape of the bayonet. The push plate slides along the guide strip through the bayonet. At least two bayonets are provided on one side, which are respectively provided in the upper part and the lower part. The inner wall of the accommodation cavity is provided with guide strips corresponding in number and position, which can effectively limit the movement of the push plate, so that the push plate moves smoothly, so as to push the airbag relatively flatly. Among them, the design of the guide strip takes into account the installation occupancy of the frame to avoid interference problems.

[0042] Further, as Figure 3As shown, the second support frame 400 is of a U-shaped frame structure. The turning part of the second support frame 400 is fixedly installed on the top surface of the support body 210 through bolts, extends and protrudes towards the direction of the first floating platform on both sides, and a sleeve 410 is fixedly provided at the end. The axis of the sleeve extends along the length direction of the support body; a support block 420 is installed in the sleeve 410 through a pin. The support block 420 extends and protrudes towards the center side of the second floating platform 200, and the protruding part is of a columnar structure; as Figure 6 , Figure 7 shown, on both sides of the middle part of the first support frame 300, support grooves 310 are fixedly provided. On the opposite sides of the support grooves 310, support pipes 320 extending along the length direction of the first floating platform are communicated. The inner diameter of the support pipes 320 is adapted to the diameter of the protruding part of the support block 420. The second support frame 400 is rotationally connected to the two support pipes 320 through the support block 420; by using a mounted support block as the connecting component between the sleeve and the support pipe, during installation, the positions of the sleeve and the support pipe need to be closely aligned first, and then the support block is inserted towards the sleeve, so that the columnar part of the support block is inserted into the support pipe, and then the support block is fixed on the sleeve through a pin, thereby forming a rotational fit; further, the inner wall of the sleeve is of a rhombic hole structure, and the shape of the support block inserted into the sleeve is also rhombic, which can effectively strengthen the connection between the support block and the sleeve, prevent the support block from rotating, and ensure the synchronous movement of the support block and the second support frame; a locking mechanism 500 is arranged at the support grooves 310 and the support pipes 320 for locking the support block 420, thereby limiting the placement position of the second support frame 400.

[0043] Further, as Figures 6 to 9 shown, the locking mechanism 500 includes a turntable 510 and two locking rods 520; the locking rods 520 are of a square bar structure. At least one guide ring 321 is fixedly provided on the inner wall of the support pipe 320. The inner ring shape of the guide ring 321 is adapted to the shape of the locking rod 520; one end of the locking rod 520 extends into the support groove 310, and a roller 530 extending vertically is installed on the top surface of the end; two arc-shaped holes 511 corresponding to the roller are provided on the turntable 510. The roller 530 is movably passed through the arc-shaped holes 511. When the turntable rotates, the locking rod can be driven to move back and forth; a first card slot 421 is provided on the wall surface of the support block 420 close to the support groove. The shape of the first card slot 421 is adapted to the shape of the locking rod 520. When the locking rod is inserted into the first card slot, the support block is locked, thereby realizing the locking of the second support frame; this structural design can drive the two locking rods to move by adjusting the turntable, so as to lock or unlock and adjust the two support blocks at the same time, facilitating the rotation and swing of the second support frame and realizing the required unfolding and folding effects.

[0044] Furthermore, a cover 330 is installed on the top of the bracket 310. A second round hole is provided in the middle of the cover. A cylinder 513 is fixedly provided at the center of the top surface of the turntable 510. The cylinder passes through the cover through the second round hole and extends outwards. A handle 540 is installed at the top end of the cylinder 513; a cross-shaped chuck 512 is fixedly provided in the middle of the bottom surface of the turntable 510. A second card slot 311 is provided at the bottom of the groove of the bracket 310. The shape of the second card slot 311 is adapted to the shape of the chuck 512; when the turntable rotates to be restricted by the roller, the position of the chuck corresponds to the position of the second card slot; by setting the chuck and the second card slot, a locking effect can be added to the rotation of the turntable. Only when the chuck disengages from the second card slot can the turntable be rotated and adjusted; moreover, the position where the chuck and the second card slot match corresponds to the position where the roller shaft and the two ends of the arc-shaped hole cooperate. When the turntable rotates to drag the pull rod to disengage from the first card slot or push the push rod into the first card slot, the chuck just corresponds to the position of the second card slot, and the downward-moving chuck can be inserted into the second card slot to complete the locking;

[0045] A spring 600 is provided inside the bracket 310. The spring 600 is clamped between the turntable 510 and the cover 330 to provide a downward pressing elastic force for the turntable; by pulling the handle, the elastic force of the spring can be overcome, and the chuck can be disengaged from the second card slot; in addition to preventing the chuck from disengaging from the second card slot and maintaining the locking effect, the design of the spring can also provide a certain resistance for pulling the turntable, giving it a certain sense of adjustment and facilitating operation.

[0046] Furthermore, the roller includes a support bolt and a bushing. The bottom end of the support bolt is threadedly connected to the lock rod. The diameter of the middle part of the support bolt is larger than the diameter of the bottom end. The bushing is sleeved on the middle position of the support bolt. The outer diameter of the bushing is adapted to the width of the arc-shaped hole to form a rotational support effect, which can facilitate the rotational adjustment of the turntable; moreover, the head of the support bolt can also be used as a blocking part for the upper limit of the upward movement of the turntable. When the turntable moves upward to abut against the head of the support bolt, the chuck disengages from the second card slot, so as to remind that the handle can be rotated to adjust the turntable, which is convenient for actual adjustment and use.

[0047] Furthermore, the top surface of the cover is recessed downward to form a sunken groove. The second round hole is provided in the middle of the bottom of the sunken groove. The handle is arranged in the sunken groove, so that the handle is in a sunken position when not adjusted, making the overall structure more compact.

[0048] Furthermore, as Figure 10 shown, the first support frame and the second support frame are also provided with holes for installing the drone foot seat. The drone can be loaded through the seat, so that the whole has an additional function of flight. It can be combined according to different usage requirements to further expand the applicability; among them, the drone is preferably a foldable drone. After the whole is folded, the overall structure can be further compressed to reduce the occupied space.

[0049] The present invention is described by way of preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited by the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application belong to the scope of protection of the present invention.
