Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a landing gear for a vertical take-off and landing (VTOL) UAV. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently.

[0003] Patent publication number CN216762150U discloses a drone landing gear, including a fixed plate detachably connected to the bottom of the drone body, a fixed rod fixedly connected to the bottom of the drone body with a vertical axis, and four support mechanisms set on the fixed plate; the fixed rod passes through the fixed plate in a vertical direction.

[0004] To address the issue of landing gear malfunctions due to a lack of cushioning upon contact with the ground, existing technologies employ shock absorbers and springs to cushion the impact during landing. However, this method still results in landing gear damage and unusability, making replacement difficult. Utility Model Content

[0005] The purpose of this invention is to provide a landing gear for a vertical take-off and landing unmanned aerial vehicle (UAV) to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A vertical take-off and landing (VTOL) unmanned aerial vehicle (UAV) landing gear includes a UAV body, a protective mechanism on the surface of the UAV body, and a support mechanism at the bottom of the UAV body.

[0008] The protective mechanism includes a clamping block, which is movably mounted on the surface of the drone body, and a movable plate is movably connected to the surface of the clamping block.

[0009] A further improvement of this utility model is that: the surface of the movable plate is provided with a slot, and a clamping block is fixedly installed on the surface of the clamping block.

[0010] A further improvement of the present invention is that the protective mechanism further includes a support frame, which is fixedly installed at the bottom end of the clamping block, and a fixing seat is fixedly installed on the surface of the support frame.

[0011] A further improvement of this utility model is that: the top of the fixing seat is provided with a groove, the groove at the top of the fixing seat is adapted to the body of the drone, the inside of the fixing seat is provided with a groove, a spring is fixedly installed inside the fixing seat, and one end of the spring is provided with a base plate.

[0012] A further improvement of the present invention is that the support mechanism includes a first rotating shaft, which is fixedly installed at the bottom of the drone body, and a first electronic telescopic rod is rotatably connected to the surface of the first rotating shaft.

[0013] A further improvement of this utility model is that the width of the first electronic telescopic rod is adapted to the groove at the bottom of the drone body, and a support rod is fixedly installed at the output end of the first electronic telescopic rod.

[0014] A further improvement of the present invention is that the support mechanism further includes a second rotating shaft, which is fixedly installed at the bottom of the drone body. A second electronic telescopic rod is rotatably connected to the surface of the second rotating shaft, and the width of the second electronic telescopic rod is adapted to the width of the groove at the bottom of the drone body.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a landing gear for a vertical take-off and landing (VTOL) drone. It employs a combination of a drone body, clamping blocks, a support frame, a movable plate, locking blocks, locking slots, a fixed seat, a base plate, and springs. By aligning the clamping blocks with the wings of the drone body (with blade bases at the four corners of the wings), and the fixed seat positioned below the blade bases, pressing the movable plate causes it to close towards the clamping blocks. When the movable plate contacts the locking blocks, it slightly deforms and lifts. When the locking slot aligns with the locking blocks, the locking blocks engage within the slots, fixing the clamping blocks to the wings of the drone body. The support frame supports the fixed seat. When the drone lands without the support frame disengaging, the base plate can preferentially contact the ground. Upon contact with the ground, the base plate compresses the springs, providing cushioning upon landing and protecting the drone body from damage. When the protective mechanism needs to be removed or replaced, the movable plate is engaged, causing deformation and disengaging the locking blocks from the locking slots, allowing for removal of the protective mechanism. This improves the adaptability of the device.

[0017] 2. This utility model provides a landing gear for a vertical takeoff and landing (VTOL) drone. It employs a combination of the drone body, a first rotating shaft, a first electronic telescopic rod, a second electronic telescopic rod, a support rod, and a second rotating shaft. The angles of the first and second electronic telescopic rods are adjusted by rotating the first and second rotating shafts, adapting to vertical landings on various slopes. Both the first rotating shaft and the first electronic telescopic rod, and the second electronic telescopic rod and the second rotating shaft, are interference fits, ensuring that the angles do not easily change during use. When the drone body needs to adjust its takeoff angle, the first and second electronic telescopic rods extend and retract, driving the support rod and changing the tilt angle of the drone body, thus altering the takeoff angle. When the support mechanism is not needed, it can be folded into a groove at the bottom of the drone body by rotating the support rod, improving the adaptability of the device.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides a landing gear for a vertical take-off and landing (VTOL) unmanned aerial vehicle (UAV), including a UAV body 1. A protective mechanism 2 is provided on the surface of the UAV body 1, and a support mechanism 3 is provided at the bottom of the UAV body 1. The protective mechanism 2 includes a clamping block 21, which is movably mounted on the surface of the UAV body 1. A movable plate 23 is movably connected to the surface of the clamping block 21. A slot 25 is provided on the surface of the movable plate 23. A locking block 24 is fixedly mounted on the surface of the clamping block 21. The protective mechanism 2 also includes a support frame 22, which is fixedly mounted at the bottom of the clamping block 21. A fixing seat 26 is fixedly mounted on the surface of the support frame 22. A groove is provided at the top of the fixing seat 26, which is adapted to the UAV body 1. A groove is provided inside the fixing seat 26, and a spring 28 is fixedly mounted inside the fixing seat 26. A base plate 27 is provided at one end of the spring 28.

[0027] In this embodiment, by aligning the clamping block 21 with the wing of the drone body 1, and the four corners of the drone body 1 having fan blade bases, and the fixing seat 26 being secured below the fan blade bases, pressing the movable plate 23 causes the movable plate 23 to close towards the clamping block 21. When the movable plate 23 contacts the locking block 24, the movable plate 23 slightly deforms and lifts up. When the locking slot 25 aligns with the locking block 24, the locking block 24 engages in the locking slot 25, thus fixing the clamping block 21 to the wing of the drone body 1. The support frame 22 supports the fixing seat 26. When the drone lands without opening the support frame, the base plate 27 can preferentially contact the ground. When the base plate 27 contacts the ground, it compresses the spring 28, providing cushioning when the drone body 1 lands, protecting the drone body 1 from damage. When the protective mechanism 2 needs to be removed and replaced, the movable plate 23 is engaged, causing the movable plate 23 to deform and the locking block 24 to disengage from the locking slot 25, thus removing the protective mechanism 2, improving the adaptability of the device.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the support mechanism 3 includes a first rotating shaft 31, which is fixedly installed at the bottom of the drone body 1. A first electronic telescopic rod 32 is rotatably connected to the surface of the first rotating shaft 31. The width of the first electronic telescopic rod 32 is adapted to the groove at the bottom of the drone body 1. A support rod 34 is fixedly installed at the output end of the first electronic telescopic rod 32. The support mechanism 3 also includes a second rotating shaft 35, which is fixedly installed at the bottom of the drone body 1. A second electronic telescopic rod 33 is rotatably connected to the surface of the second rotating shaft 35. The width of the second electronic telescopic rod 33 is adapted to the width of the groove at the bottom of the drone body 1.

[0030] In this embodiment, the angles of the first electronic telescopic rod 32 and the second electronic telescopic rod 33 are adjusted by rotating the first rotating shaft 31 and the second rotating shaft 35 to adapt to vertical landing on various slopes. At the same time, the first rotating shaft 31 and the first electronic telescopic rod 32, and the second electronic telescopic rod 33 and the second rotating shaft 35 are all interference fit, so that the angles will not easily change during use. When the drone body 1 needs to adjust the takeoff angle, the first electronic telescopic rod 32 and the second electronic telescopic rod 33 extend and retract, driving the support rod 34, so that the tilt angle of the drone body 1 changes, thereby changing the takeoff angle. When the support mechanism 3 is not needed, the support mechanism 3 can be folded into the groove at the bottom of the drone body 1 by rotating the support rod 34, which improves the adaptability of the device.

[0031] The working principle of the landing gear of this vertical take-off and landing drone will be explained in detail below.

[0032] like Figure 1-5 As shown, by aligning the clamping block 21 with the wing of the drone body 1, and with the fan blade bases provided at the four corners of the wing, and the fixing seat 26 below the fan blade base, pressing the movable plate 23 causes it to close towards the clamping block 21. When the movable plate 23 contacts the locking block 24, it slightly deforms and lifts up. When the locking slot 25 aligns with the locking block 24, the locking block 24 engages in the locking slot 25, thus fixing the clamping block 21 to the wing of the drone body 1. The support frame 22 supports the fixing seat 26. When the drone lands without opening the support frame, the base plate 27 can make contact with the ground first. When the base plate 27 contacts the ground, it compresses the spring 28, providing cushioning for the drone body 1 upon landing and protecting it from damage. When the protective mechanism 2 needs to be removed or replaced, the movable plate 23 is engaged, causing it to... Deformation causes the locking block 24 to disengage from the slot 25, allowing the protective mechanism 2 to be removed. Simultaneously, when the support mechanism 3 is needed, the rotation of the first rotating shaft 31 and the second rotating shaft 35 adjusts the angles of the first electronic telescopic rod 32 and the second electronic telescopic rod 33, adapting to vertical landings on various slopes. Furthermore, the first rotating shaft 31 and the first electronic telescopic rod 32, and the second electronic telescopic rod 33 and the second rotating shaft 35 are all interference fits, ensuring that the angles do not easily change during use. When the drone body 1 needs to adjust its takeoff angle, the first electronic telescopic rod 32 and the second electronic telescopic rod 33 extend and retract, driving the support rod 34, causing a change in the tilt angle of the drone body 1, thereby altering the takeoff angle. When the support mechanism 3 is not needed, rotating the support rod 34 folds the support mechanism 3 into the groove at the bottom of the drone body 1, improving the device's adaptability.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
