Description

Technical Field

[0001] This utility model relates to the field of aviation equipment technology, specifically to a foldable take-off and landing platform for aircraft. Background Technology

[0002] With the rapid development and widespread application of drone technology, the demand for aircraft, especially drone take-off and landing platforms, is increasing. Drones play a vital role in various fields such as agricultural spraying, environmental monitoring, logistics transportation, and emergency rescue. However, as a key component of their ground support systems, drone take-off and landing platforms face several challenges. Traditional take-off and landing platforms are often bulky and heavy, making them difficult to carry and deploy, thus limiting the rapid response capabilities of drones in the field or in emergency situations.

[0003] However, existing take-off and landing platforms are often large and heavy, making them inconvenient to carry and deploy quickly, especially in situations requiring rapid response, such as in the field or emergency rescue. The deployment and storage process of existing platforms is cumbersome, requiring multiple people to work together, which increases the difficulty of operation and time costs. Storage requires disassembling multiple parts, which is a complex and time-consuming process and not conducive to rapid site changes or multiple uses. Utility Model Content

[0032] In this embodiment, the folding component 3 and the support module 4 constitute a foldable take-off and landing platform for aircraft according to this application.

[0033] It should be noted that the base 1 is rectangular in shape and made of high-strength aluminum alloy, possessing good strength and lightweight properties. The take-off and landing platform 2 is a rectangular plate made of aluminum alloy. The folding assembly 3 includes a rotating base 31 made of aluminum alloy, and the support module 4 includes outer legs 41 made of aluminum alloy. The base 1 provides overall structural support. The take-off and landing platform 2 is used for the take-off and landing of the UAV. The folding assembly 3 achieves the folding and unfolding of the extended platform 21 through the rotating base 31. The support module 4 provides stable support through the outer legs 41 and inner legs 42, ensuring the stability of the take-off and landing platform 2.

[0034] In this embodiment, the aircraft can be a fixed-wing aircraft, a rotorcraft, a drone, a small aircraft, etc. The fixed-wing aircraft can be, but is not limited to, commercial passenger planes, cargo planes, private planes, etc. This embodiment uses a drone as an example for description.

[0035] In addition, in this embodiment, when the storage device needs to be folded, the user rotates the two sets of locking nuts 35 to release the rotation lock of the rotating blocks 33 on both sides of the extension platform 21 in the rotating groove 32. Then, the positioning pin 34 is rotated out, and the two sets of extension platforms 21 are flipped upward 180 degrees onto the lifting platform 2. Then, the positioning pin 34 is aligned with the threaded hole at the upper end of the rotating base 31 and rotated in. The locking nuts 35 are tightened again to lock the rotation angle of the rotating blocks 33. After that, the user can lift the lifting platform 2 upward and separate it from the top slot of the base 1 for easy storage.

[0036] Specifically, the take-off and landing platform 2 includes an extension platform 21, which is rotatably disposed on both sides of the take-off and landing platform 2.

[0037] In this embodiment, the extended platform 21 is made of aluminum alloy. The extended platform 21 can be folded and unfolded by rotation, increasing the usable area of ​​the take-off and landing platform 2 and adapting to drones of different sizes.

[0038] Specifically, the folding assembly 3 includes: a rotating groove 32, which is formed inside the rotating base 31; a rotating block 33, which is set on both sides of the extension platform 21 near the lifting platform 2, and is embedded in the rotating groove 32 and rotates, and has a threaded hole on the side away from the extension platform 21; a positioning pin 34, which is threadedly engaged in the threaded holes of the rotating base 31 and the rotating block 33; and a locking nut 35, which is threadedly engaged with the positioning pin 34.

[0039] With this configuration, the rotating block 33 is a rectangular block made of aluminum alloy, the positioning pin 34 is cylindrical and made of metal with external threads on its outer wall, and the locking nut 35 is a hexagonal nut made of metal. The rotating block 33 rotates within the rotating groove 32, and the positioning pin 34 and the locking nut 35 are connected by threads to fix the position of the rotating block 33, thereby enabling the folding and unfolding of the extension platform 21 and ensuring the stability and portability of the lifting platform 2.

[0040] Example 2:

[0041] Based on Example 1, the user then rotates the handwheel 431 to drive the first bevel gear 432 to rotate. The first bevel gear 432 meshes with the second bevel gear 433 to rotate. The second bevel gear 433 drives the threaded rod 434 to rotate. The threaded rod 434 meshes with the internal thread of the inner support leg 42, causing the inner support leg 42 to slide upward in the bottom groove of the outer support leg 41 for easy storage.

[0042] Specifically, the support module 4 includes: an inner support leg 42 that slides up and down inside the outer support leg 41; and an adjustment component 43 that is disposed inside the outer support leg 41.

[0043] The inner outrigger 42 is cylindrical and made of aluminum alloy. The inner outrigger 42 slides inside the outer outrigger 41. The adjustment component 43 adjusts the height of the inner outrigger 42 through the handwheel 431, the first bevel gear 432, the second bevel gear 433 and the threaded rod 434 to ensure the stability and adaptability of the lifting platform 2.

[0044] Specifically, the adjustment assembly 43 includes: a handwheel 431, rotatably disposed on one side of the top of the outer support leg 41; a first bevel gear 432, rotatably disposed inside the top of the outer support leg 41 and key-connected to the rotating rod of the handwheel 431; a second bevel gear 433, rotatably disposed inside the top of the outer support leg 41 and meshing with the bottom of the first bevel gear 432; and a threaded rod 434, rotatably disposed inside the outer support leg 41, with its top key-connected to the second bevel gear 433 and its bottom threadedly engaged with the inside of the inner support leg 42.

[0045] In this embodiment, the handwheel 431 is a circular wheel made of metal, the first bevel gear 432 is a circular gear made of metal, the second bevel gear 433 is a circular gear made of metal, and the threaded rod 434 is cylindrical and made of metal. The handwheel 431 drives the threaded rod 434 to rotate through the first bevel gear 432 and the second bevel gear 433. The threaded rod 434 engages with the internal thread of the inner support leg 42, causing the inner support leg 42 to slide upward in the bottom groove of the outer support leg 41, thereby realizing the height adjustment of the support module 4 and ensuring the stability and adaptability of the lifting platform 2.

[0046] In actual use, when the folding and storage device is needed, the user first rotates the two sets of locking nuts 35 to release the rotation lock of the rotating blocks 33 on both sides of the extension platform 21 in the rotating groove 32. Then, the positioning pin 34 is rotated out, and the two sets of extension platforms 21 are flipped upwards 180 degrees onto the lifting platform 2. Then, the positioning pin 34 is aligned with the threaded hole at the upper end of the rotating base 31 and rotated in. The locking nuts 35 are tightened again to lock the rotation angle of the rotating blocks 33. After that, the user can lift the lifting platform 2 upwards and separate it from the top slot of the base 1 for easy storage. Then, the user rotates the handwheel 431 to drive the first bevel gear 432 to rotate. The first bevel gear 432 meshes with the second bevel gear 433 to rotate. The second bevel gear 433 drives the threaded rod 434 to rotate. The threaded rod 434 meshes with the internal thread of the inner support leg 42, causing the inner support leg 42 to slide upwards in the bottom groove of the outer support leg 41 for easy storage.
