The two chain window openers are respectively installed in the center of both sides of the frame. The ends of the chains of the chain window openers are connected to the center of the push plates through U-shaped pieces. The input shafts of the two chain window openers are meshed with the adjusting rod through a gear set for transmission. Rotating the adjusting rod can drive the chain of the chain window openers to extend and retract, thereby driving the push plates to perform outward pushing and retraction actions.

[0009] In a preferred embodiment of this invention, the push plate has slots on both sides; the inner wall of the receiving cavity is provided with guide strips, the shape of which is adapted to the shape of the slots; the push plate slides along the guide strips through the slots.

The bend of the second support frame is fixedly installed on the top surface of the support body by bolts. Both sides extend and protrude towards the first floating platform, and a sleeve is fixed at the end. The axis of the sleeve extends along the length of the support body. A support block is installed inside the sleeve by a pin. The support block extends and protrudes towards the center of the second floating platform, and the protrusion is a columnar structure. The middle two sides of the first support frame are fixedly provided with slots. Support pipes extending along the length of the first floating platform are connected to the opposite sides of the slots. The inner diameter of the support pipes is adapted to the diameter of the protrusion of the support block. The second support frame is rotatably connected to the two support pipes through the support block. A locking mechanism is provided at the slots and support pipes to lock the support block, thereby limiting the placement position of the second support frame.

[0011] In a preferred embodiment of this invention, the locking mechanism includes a turntable and two locking rods. The locking rods are square bars, and at least one guide ring is fixedly provided on the inner wall of the support tube.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model provides a foldable trimaran floating platform structure for amphibious unmanned aerial vehicles (UAVs), including a first floating platform and two second floating platforms located on both sides of the first floating platform. A booster is installed at the rear end of the first floating platform. A first support frame is installed on the top surface of the first floating platform, and a second support frame is installed on the top surface of the second floating platforms. The second support frames extend outwards from the first floating platform and are rotatably connected to both sides of the first support frame. Locking mechanisms are installed on both sides of the first support frame to lock the second support frames in horizontal and vertical positions. This structural design allows the second floating platforms to have folding and unfolding functions. When in use, they can be unfolded to provide a wide range of support for stable navigation and movement. They can also be folded during transport, compressing the overall structure, reducing the space occupied, and facilitating transfer and transportation. Furthermore, the locking mechanisms lock the rotating parts of the first and second support frames, and can be unlocked by adjusting the locking mechanisms, allowing for adjustment of the placement position of the second support frames, making operation convenient.

[0015] The second floating platform includes a support body and airbags installed at both ends of the support body. When the airbags are adjusted to extend outside the support body, the exposed part of the airbags inflates into a boat-shaped structure, which is aligned with the end face of the support body. The airbags can also be adjusted to deflate the exposed part and retract into the support body. This structural design allows the second floating platform to have a secondary adjustment function. It can be unfolded to expand the support range when in use and reduced in size when stored, thus reducing space occupation, facilitating transfer and transportation, and further enhancing the foldable function.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 , Figure 2As shown in the figure, a foldable trimaran floating platform structure for amphibious unmanned aerial vehicles is disclosed in a specific embodiment of the present invention, including a first floating platform 100 and two second floating platforms 200 disposed 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 frames extend outward from the first floating platform and are respectively rotatably connected to 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 when placed in a horizontal or vertical position; the second floating platform 200 includes a support body 210 and airbags 220 installed at both ends of the support body 210. When the airbags are adjusted to extend outside the support body, the exposed part of the airbags inflates into a boat-shaped structure and connects to the end face of the support body; the exposed part of the airbags can be deflated and retracted into the support body by adjustment.

[0030] The aforementioned foldable trimaran floating platform structure for amphibious unmanned aerial vehicles allows the second floating platform to be both foldable and unfoldable. When in use, it can be unfolded to provide a wide range of support and achieve stable navigation and movement; it can also be folded during transport, tightening the overall structure, reducing the external space occupied, and facilitating transfer and transportation. Furthermore, a locking mechanism is used to lock the rotating parts of the first and second support frames, and the locking mechanism can be adjusted to unlock and then adjust the placement position of the second support frame, making it convenient to use and operate.

[0031] In addition, the two ends of the second floating platform are airbags, which gives the second floating platform a secondary adjustment function. It can be inflated and expanded during use to increase the support range, and deflated to reduce the volume when stored, thereby reducing space occupation, facilitating transfer and transportation, and further enhancing the foldable function.

[0032] Furthermore, such as Figures 3 to 5As shown, the second floating platform 200 includes a support body 210, two airbags 220, and a pushing mechanism 230. The support body 210 has a receiving cavity 211 in its middle and storage cavities 212 at both ends. The storage cavities 212 and the receiving cavity 211 are connected by a first through hole 213. Each airbag 220 includes a first bladder, a second bladder, and a third bladder connected sequentially. The two airbags are respectively installed at both ends of the receiving cavity, with the first bladder located at the receiving cavity 211 and the second bladder located at... At the first through hole 213, the third bladder is located at the receiving cavity 212; the pushing mechanism 230 is installed in the middle of the receiving cavity 211, and the pushing mechanism 230 is provided with two push plates 231. The two push plates can be adjusted to push and move towards both ends of the receiving cavity; the airbag is in a deflated state with incomplete inflation. When the push plates push towards the end of the receiving cavity, the first bladder can be squeezed and pushed, causing the second and third bladders to inflate and expand. The third bladder has a boat-shaped structure that protrudes outward and is connected to the end face of the support body.

[0033] When the pusher moves toward the center of the accommodating cavity, it releases the squeezing and pushing of the first bladder, and squeezing the third bladder allows gas to flow to the second bladder and the first bladder, and the third bladder can be put into the receiving cavity.

[0034] This structural design uses partially inflated airbags as the basis for adjustment and transformation. By using a pushing mechanism to compress the airbags, the direction of the gas inside is limited. When deployment is needed, the third airbag inflates and expands, taking on a boat-shaped profile that connects to the end of the support body. This gives the second floating platform a boat-shaped structure that tapers at both ends, increasing overall buoyancy and reducing water resistance. When the pushing mechanism retracts its push plate and releases the pressure on the airbags, the airbags deflate. For further retraction, the third airbag can be manually pushed to push the gas into the second and first airbags, causing the third airbag to deflate into the retractable cavity, thus achieving retraction and shrinkage. The structure is more compact.

[0035] Furthermore, a second cover plate 250 is provided on the outer side of the opening of the storage cavity 212. The top of the second cover plate 250 is connected to the top surface of the end of the support body 210 by a hinge. Locking knobs 251 are installed on both sides of the second cover plate 250. The end face of the support body is provided with corresponding threaded holes. The second cover plate can be fixed to the end face of the support body by locking knobs to seal the port of the storage cavity. When passing through the second cover plate, the third bladder inside the storage cavity is protected and blocked to prevent it from falling out.

[0036] Furthermore, the air inlet of the airbag is located in the first airbag body, and the airbag is not inflated during installation. After it is installed in place, a preset amount of gas is injected into it to meet the adjustable adjustment requirements.

[0037] Furthermore, a first cover plate 240 is provided on the outer side of the top of the accommodating cavity 211. The first cover plate is fixed to the top surface of the support body by bolts to seal the top opening of the accommodating cavity. The adjusting rod of the pushing mechanism moves through the middle of the first cover plate and extends outward for adjustment.

[0038] Furthermore, such as Figure 5 As shown, the pushing mechanism 230 includes a frame 232, an adjusting rod 233, two push plates 231, and two chain window openers 234. The frame 232 is fixedly installed in the middle of the receiving cavity 211 by bolts, and the adjusting rod 233 is installed in the middle of the frame 232 by bearings. The two chain window openers 234 are respectively installed in the middle of the two sides of the frame 232. The end of the chain of the chain window opener 234 is connected to the center of the push plate 231 by a U-shaped piece. The input shaft of the two chain window openers 234 is connected to the adjusting rod 233 by gears. Group 235 meshing transmission; the chain of the chain window opener can be extended and retracted by rotating the adjusting rod, which is used to drive the push plate to perform external pushing and retraction actions; the chain window opener, as a structural component for extension and retraction, can provide a large pushing stroke, effectively squeezing the airbag, so that the third airbag can quickly inflate and expand to the required size; when it needs to be retracted, the support chain retracts into the chain box, without taking up too much internal space, providing enough space for the first airbag to move back, and naturally facilitating the retraction of the third airbag into the storage cavity.

[0039] Furthermore, the first cover plate is provided with a first round hole corresponding to the adjusting rod, and a sealing ring is provided on the inner wall of the first round hole. The adjusting rod extends out of the first cover plate through the sealing and moving through the first round hole. A prism block is fixed at the top of the adjusting rod so that external tools such as wrenches or electric wrenches can be sleeved on it for easy rotation and adjustment.

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

[0041] Furthermore, the push plate has latches on both sides; the inner wall of the accommodating cavity has corresponding guide strips, the shape of which matches the shape of the latches; the push plate slides along the guide strips through the latches; at least two latches are provided on one side, located at the upper and lower parts respectively, and the inner wall of the accommodating cavity has guide strips of corresponding number and position, which can effectively limit the movement of the push plate, thereby allowing the push plate to move smoothly so as to push the airbag relatively flat; the design of the guide strips takes into account the installation space of the frame to avoid interference problems.

[0042] Furthermore, such as Figure 3As shown, the second support frame 400 is a U-shaped frame structure. The bend of the second support frame 400 is fixedly installed on the top surface of the support body 210 by bolts. Both sides extend and protrude towards the first floating platform, and a sleeve 410 is fixed at the end. The axis of the sleeve extends along the length of the support body. A support block 420 is installed inside the sleeve 410 by a pin. The support block 420 extends and protrudes towards the center of the second floating platform 200, and the protrusion is a columnar structure. Figure 6 , Figure 7 As shown, the first support frame 300 has slots 310 fixed on both sides of its middle section. Support tubes 320 extending along the length of the first floating platform are connected to opposite sides of the slots 310. The inner diameter of the support tubes 320 matches the diameter of the protrusion of the support block 420. The second support frame 400 is rotatably connected to the two support tubes 320 via the support block 420. The added support block serves as the connecting component between the sleeve and the support tube. During installation, the sleeve and support tube must first be aligned closely, and then the support block is inserted into the sleeve. The columnar part of the support block is inserted into the support tube, and the support block is fixed to the sleeve by a pin, thus forming a rotational fit. Furthermore, the inner wall of the sleeve has a prismatic hole structure, and the shape of the support block inserted into the sleeve is also prismatic, which can effectively strengthen the connection between the support block and the sleeve, prevent the support block from rotating, and ensure that the support block and the second support frame move synchronously. The locking mechanism 500 is provided at the bracket 310 and the support tube 320 to lock the support block 420, thereby limiting the placement position of the second support frame 400.

[0043] Furthermore, such as Figures 6 to 9 As shown, the locking mechanism 500 includes a turntable 510 and two locking rods 520. The locking rods 520 are square bars, and at least one guide ring 321 is fixedly provided on the inner wall of the support tube 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 groove 310, and a vertically extending roller 530 is installed on the top surface of the end. The turntable 510 has two arc-shaped holes 511 corresponding to the rollers, and the rollers 530 are movably inserted through the arc-shaped holes 511. When the turntable rotates... When the locking rod is inserted, it can move back and forth. The support block 420 has a first slot 421 on its wall near the bracket. The shape of the first slot 421 is adapted to the shape of the locking rod 520. When the locking rod is inserted into the first slot, it locks the support block, thereby locking the second support frame. This structural design can drive the two locking rods to move by adjusting the turntable, thereby locking or unlocking the two support blocks at the same time, which facilitates the rotation and swing of the second support frame to achieve the required unfolding and folding effect.

[0044] Furthermore, a cover 330 is installed on the top of the tray 310, and a second circular 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 extends outward through the cover via the second circular hole, and a handle 540 is installed at the top of the cylinder 513. A cross-shaped locking head 512 is fixedly provided in the middle of the bottom surface of the turntable 510, and a second locking groove 311 is provided at the bottom of the tray 310. The shape of the second locking groove 311 is adapted to the shape of the locking head 512. When the turntable rotates to the point where it is restricted by the roller, The position of the locking head corresponds to the position of the second locking slot. By setting the locking head and the second locking slot, a locking effect can be added to the rotation of the turntable. The turntable can only be rotated and adjusted when the locking head is disengaged from the second locking slot. Furthermore, the matching position of the locking head and the second locking slot corresponds to the position of the roller shaft and the two ends of the arc-shaped hole. When the turntable rotates to the point where the drag rod is disengaged from the first locking slot or the push rod is inserted into the first locking slot, the locking head is exactly aligned with the position of the second locking slot, and the downward-moving locking head can be inserted into the second locking slot to complete the locking.

[0045] The tray 310 is equipped with a spring 600, which is clamped between the turntable 510 and the cover 330 to provide a downward pressing force for the turntable. The spring force can be overcome by pulling the handle, and the locking head can be disengaged from the second slot. In addition to preventing the locking head from disengaging from the second slot and maintaining the locking effect, the spring design can also provide a certain resistance to lifting the turntable, so that it has a certain adjustment feel and is easy to operate.

[0046] Furthermore, the roller includes a support bolt and a bushing. The bottom end of the support bolt is threaded onto the locking rod. The diameter of the middle part of the support bolt is larger than the diameter of the bottom end. The bushing is appropriately fitted in the middle position of the support bolt. The outer diameter of the bushing matches the width of the arc-shaped hole, forming a rotational support effect, which facilitates the rotational adjustment of the turntable. In addition, the head of the support bolt can also serve as an obstacle to the upper limit of the turntable. When the turntable moves up to the point where it abuts the head of the support bolt, the chuck disengages from the second slot, thereby reminding the turntable to be adjusted by rotating the handle, which is convenient for actual adjustment and use.

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

[0048] Furthermore, such as Figure 10 As shown, the first and second support frames are also provided with holes for mounting drone foot brackets. Drones can be mounted through the brackets, which increases the overall flight capability. They can be combined according to different usage needs to further expand their applicability. Among them, the drones are preferably foldable drones, which can further compress the overall structure and reduce space occupation after being folded.
