Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV landing gear and a UAV. Background Technology
[0002] Existing technology patent CN208775007U discloses a drone landing gear and a drone. The landing gear includes three elastic support legs made of sheet metal, with an included angle of 120 degrees between adjacent elastic support legs, and the three elastic support legs are distributed in a triangle. The drone landing gear has three-point ground contact, resulting in good landing stability. The long strip of sheet metal has inherent elasticity, providing good cushioning. The structure is extremely simple and lightweight, conforming to the lightweight design trend of drones.
[0003] When in use, this device cannot effectively protect the drone rotor. Collisions between the rotor and other objects can easily cause the drone to fall. Furthermore, the landing gear has high frictional resistance when the drone lands, making it easy for the drone to tip over due to inertia. Therefore, a drone landing gear and drone are needed to meet the usage requirements. Utility Model Content
[0004] The purpose of this invention is to provide a drone landing gear and a drone to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drone landing gear and a drone, including the drone body, and further comprising,
[0006] A support base is fixedly installed at the bottom of the drone body to support the drone body for takeoff;
[0007] A landing gear mechanism, housed within the support base, is used for landing the UAV body;
[0008] A landing gear lifting mechanism is provided on the support base and the landing gear mechanism, and is used to adjust the retraction and extension of the landing gear mechanism;
[0009] A protective cover is installed over the rotor of the drone body to protect the rotor.
[0010] A protective cover disassembly mechanism is provided on the drone body and the protective cover for disassembling the protective cover.
[0011] Preferably, the landing gear mechanism includes a landing gear disposed within the support base, a roller mounting component fixedly mounted on the bottom of the landing gear, and a roller rotatably mounted within the roller mounting component.
[0012] Preferably, the landing gear lifting mechanism includes an L-shaped plate fixedly installed on the landing gear, a threaded sleeve fixedly installed on the L-shaped plate, a screw rod rotatably installed inside the support base, and the threaded sleeve sleeved on the threaded sleeve.
[0013] Preferably, a support plate is fixedly installed on the inner wall of the support base, a drive motor is fixedly installed on the support plate, a drive shaft is fixedly installed on the output end of the drive motor, a drive gear is fixedly installed on the drive shaft, a driven gear is fixedly installed on the screw, and the drive gear and the driven gear mesh with each other.
[0014] Preferably, a guide rod is fixedly installed inside the support base, and a guide sleeve is fixedly installed on the landing gear, with the guide sleeve slidably sleeved on the guide rod.
[0015] Preferably, the protective cover disassembly mechanism includes an integrated rod fixedly installed on the protective cover, an insert block fixedly installed on the integrated rod, an insert sleeve fixedly installed on the drone body, a slot opened on the insert block, a locking rod slidably installed in the insert sleeve, and the locking rod locking into the slot.
[0016] Preferably, a support block is fixedly installed on the drone body, a telescopic spring and a guide telescopic rod are fixedly installed on the lever and the support block, and a pull ring is fixedly installed on the plug sleeve.
[0017] The beneficial effects of this utility model are:
[0018] In this invention, the landing gear mechanism, the protective cover disassembly mechanism, and the protective cover itself are designed so that the rollers, rolling on the ground, generate friction to slowly brake the drone, preventing it from tipping over due to inertia during descent. Inserting the insert block into the sleeve allows the protective cover to be placed over the drone's rotor. Moving the lever forward engages it in the slot, securing the protective cover. During flight, the protective cover prevents the drone's rotor from colliding with other objects and causing the drone to fall.
[0019] In this invention, the landing gear lifting mechanism allows the drive motor to rotate, which in turn drives the drive shaft to rotate. The rotation of the drive shaft then drives the landing gear to move downwards. The downward movement of the landing gear causes the roller mounting components and rollers to move downwards and leave the support base for landing cushioning of the UAV. The reverse rotation of the drive motor drives the roller mounting components and rollers to move upwards and enter the support base, facilitating the storage of the landing gear mechanism.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Example:
[0028] like Figure 1-5 As shown, this embodiment provides a drone landing gear and a drone, including a drone body 1, and further including: a support base 2, fixedly installed on the bottom of the drone body 1, for supporting the drone body 1 for takeoff; a landing gear mechanism 3, disposed in the support base 2, for landing the drone body 1; a landing gear lifting mechanism 4, disposed on the support base 2 and the landing gear mechanism 3, for adjusting the retraction and extension of the landing gear mechanism 3; a protective cover 5, covering the rotor of the drone body 1, for protecting the rotor; and a protective cover disassembly mechanism 6, disposed on the drone body 1 and the protective cover 5, for disassembling the protective cover 5.
[0029] The support base 2 supports the drone body 1, allowing the drone body 1 to take off while supported by the support base 2. When the drone body 1 needs to land, the landing gear lifting mechanism 4 drives the landing gear mechanism 3 to leave the support base 2. When the drone body 1 lands, the landing gear mechanism 3 can slowly brake the drone body 1, preventing it from tipping over due to inertia during descent. The protective cover 5 can be placed over the rotor of the drone body 1 using the protective cover removal mechanism 6. During flight, the protective cover 5 prevents the drone body 1 from colliding with other objects and falling off. The protective cover 5 can also be removed using the protective cover removal mechanism 6, facilitating the disassembly, replacement, and maintenance of the drone body 1's rotor.
[0030] In this embodiment of the utility model, specifically, the landing gear mechanism 3 includes a landing gear 31 disposed in the support base 2, a roller mounting component 32 is fixedly installed at the bottom of the landing gear 31, and a roller 33 is rotatably installed in the roller mounting component 32;
[0031] To prevent the drone body 1 from tipping over during landing, the roller 33 makes contact with the ground first when the drone body 1 lands. The roller 33 rolls on the ground and generates friction, which can slowly stop the drone body 1 and prevent it from tipping over due to inertia during landing.
[0032] In this embodiment of the utility model, specifically, the landing gear lifting mechanism 4 includes an L-shaped plate 41 fixedly installed on the landing gear 31, a screw sleeve 43 fixedly installed on the L-shaped plate 41, a screw rod 42 rotatably installed in the support base 2, and the screw sleeve 43 sleeved on the screw sleeve 43.
[0033] To facilitate the adjustment of the position of the landing gear mechanism 3, the rotation of the screw 42 will cause the screw sleeve 43 to move downward on the screw 42. The downward movement of the screw sleeve 43 will cause the landing gear 31 to move downward. The downward movement of the landing gear 31 will cause the roller mounting part 32 and the roller 33 to move downward and leave the support base 2.
[0034] In this embodiment of the utility model, more specifically, a support plate 44 is fixedly installed on the inner wall of the support base 2, a drive motor 45 is fixedly installed on the support plate 44, a drive shaft 46 is fixedly installed on the output end of the drive motor 45, a drive gear 47 is fixedly installed on the drive shaft 46, a driven gear 48 is fixedly installed on the screw 42, and the drive gear 47 and the driven gear 48 mesh with each other.
[0035] To drive the screw 42 to rotate, the drive motor 45 is started. The rotation of the drive motor 45 will drive the drive shaft 46 to rotate. The rotation of the drive shaft 46 will drive the drive gear 47 to rotate, which in turn will drive the driven gear 48 to rotate, and the rotation of the driven gear 48 will drive the screw 42 to rotate.
[0036] In this embodiment of the utility model, a guide rod 49 is fixedly installed inside the support base 2, and a guide sleeve 410 is fixedly installed on the landing gear 31. The guide sleeve 410 is slidably sleeved on the guide rod 49.
[0037] In order to guide the movement of the landing gear 31, the guide sleeve 410 slides on the guide rod 49 to guide the movement of the landing gear 31, so that the landing gear 31 can only move up and down.
[0038] In this embodiment of the utility model, specifically, the protective cover disassembly mechanism 6 includes an integrated rod 61 fixedly installed on the protective cover 5, an insert 62 fixedly installed on the integrated rod 61, an insert sleeve 63 fixedly installed on the drone body 1, a slot 64 opened on the insert 62, a locking rod 65 slidably installed in the insert sleeve 63, and the locking rod 65 locking into the slot 64; a support block 66 fixedly installed on the drone body 1, a telescopic spring 67 and a guide telescopic rod 68 fixedly installed on the locking rod 65 and the support block 66, and a pull ring 69 fixedly installed on the insert sleeve 63;
[0039] To facilitate the installation and removal of the protective cover 5, the insert block 62 is pre-inserted into the insert sleeve 63, allowing the protective cover 5 to be placed over the rotor of the drone body 1. Simultaneously, the telescopic spring 67 causes the locking rod 65 to move forward and engage with the slot 64, thus securing the protective cover 5. During flight, the protective cover 5 prevents the drone body 1 from colliding with other objects and falling. The guide telescopic rod 68 guides the movement of the locking rod 65, ensuring it can only move back and forth in a straight line. Pulling the locking rod 65 outwards to release it from the slot 64, and then pulling it upwards via the pull ring 69, allows for easy installation, removal, replacement, and maintenance of the drone body 1's rotor.
[0040] Working principle: In use, insert block 62 is inserted into insert sleeve 63 beforehand, which allows the protective cover 5 to be placed over the rotor of the drone body 1. Simultaneously, under the action of telescopic spring 67, the locking rod 65 moves forward and engages in slot 64, thus securing the protective cover 5. During flight, the protective cover 5 prevents the drone body 1 from colliding with other objects and falling. Guide telescopic rod 68 guides the movement of locking rod 65, ensuring it can only move back and forth in a straight line. Pulling locking rod 65 outwards to release it from slot 64, and then pulling upwards via pull ring 69, allows for easy disassembly, replacement, and maintenance of the drone body 1's rotor. Support base 2 provides support for the drone body 1, allowing it to take off while supported. When the drone body 1 needs to land, the drive motor 45 is pre-activated. The rotation of the drive motor 45 drives the drive shaft 46 to rotate, which in turn drives the drive gear 47 to rotate. The drive gear 47 then drives the driven gear 48 to rotate, which in turn drives the screw 42 to rotate. The guide sleeve 410 slides on the guide rod 49, guiding the movement of the landing gear 31 so that it can only move up and down. The rotation of the screw 42 then drives the screw sleeve 43 to move downwards on the screw 42. The downward movement of the screw sleeve 43 causes the landing gear 31 to move downwards, which in turn causes the roller mounting component 32 and the roller 33 to move downwards and leave the support base 2. When the drone body 1 lands, the roller 33 first contacts the ground. The roller 33 rolls on the ground, generating friction that slowly brakes the drone body 1, preventing it from tipping over due to inertia during descent. Inserting the insert 62 into the sleeve 63 beforehand allows the cover 5 to be placed over the rotor of the drone body 1. Simultaneously, the telescopic spring 67 causes the locking lever 65 to move forward and engage with the slot 64, thus securing the cover 5. During flight, the cover 5 prevents the drone body 1 from colliding with other objects and falling. The guide telescopic rod 68 guides the movement of the locking lever 65, ensuring it can only move forward and backward in a straight line. Pulling the locking lever 65 outwards to release it from the slot 64, and then pulling it upwards via the pull ring 69, facilitates the disassembly, replacement, and maintenance of the drone body 1's rotor.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
