Description

Technical Field

[0001] This utility model relates to the field of drone accessories technology, and in particular to a stable landing device for drones. Background Technology

[0002] As a remotely controlled flying device, drones have been widely used in various fields such as aerial photography, surveying and mapping, agricultural plant protection, and logistics transportation. During the use of drones, the stability during the landing phase directly affects the safety of the drone itself and the equipment it carries. Therefore, a stable landing device is an indispensable component of drones.

[0003] Currently, most commercially available drone stabilization landing devices use fixed mounting plates that are fixedly connected to the drone body. This fixed structure has significant drawbacks in practical use. Since the support plate needs to be in direct contact with the ground when the drone lands, it is prone to surface damage or functional failure due to wear, impact deformation, environmental corrosion, and other factors after long-term use. Furthermore, the fixed connection structure requires users to spend a lot of time disassembling the complex connection structure when replacing a damaged mounting plate. In addition, the disassembly process may cause accidental damage to the drone's shell, internal wiring, or other components, greatly reducing the device's maintenance convenience and lifespan, while increasing the cost of using the drone.

[0004] Regarding the above and existing related technologies, the inventor believes that the following defects often exist: Since the support plates on the market are all fixed to the drone body, after long-term use, the surface of the support plate will be damaged or corroded, rendering it unusable. This requires users to spend a lot of time to disassemble and replace it, or the replacement process may cause some damage to the drone body. Utility Model Content

[0005] The technical problem to be solved by this utility model is that existing technologies are all fixed to the drone body, and after long-term use, the support plate will become unusable due to surface damage and corrosion. This requires users to spend a lot of time to disassemble and replace it, or the replacement will cause some damage to the drone body. Therefore, we propose a stable landing device for drones.

[0006] To achieve the above objectives, this application adopts the following technical solution: a stable landing device for a drone, comprising a drone body, two fixed plates slidably connected to the surface of the drone body, a support plate fixedly connected to the surface of each of the two fixed plates, screws threadedly inserted into the surface of each of the two fixed plates, and four corner blocks fixedly connected to one end of each of the two screws, and two threaded grooves formed on the surface of the drone body.

[0007] Preferably, the screw has a washer slidably connected to its arc surface, and the size of the screw is adapted to the size of the washer.

[0008] Preferably, a spring washer is slidably connected to the arc surface of the screw, and the size of the screw is adapted to the size of the spring washer.

[0009] Preferably, two rotating rods are fixedly connected to the surface of the four corner blocks, and the size of the screw rods is adapted to the size of the threaded groove.

[0010] Preferably, a rubber plate is fixedly connected to the surface of the support plate, and the surface of the rubber plate has several flat grooves.

[0011] Preferably, the surface of the fixing plate is coated with a corrosion-resistant coating, which is an alumina coating.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention achieves the effect of easy disassembly of the support plate, avoiding the situation where the support plate is fixed to the drone body, and after long-term use, it becomes unusable due to surface damage and corrosion. This prevents users from having to spend a lot of time disassembling and replacing it, or causing damage to the drone body during replacement, thus improving the usability of the device.

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] Reference Figure 1-4 As shown, this utility model provides a technical solution: a stable landing device for a drone, including a drone body 1. Two fixing plates 2 are slidably connected to the surface of the drone body 1. Support plates 3 are fixedly connected to the surfaces of both fixing plates 2. Screws 4 are threaded into the surfaces of both fixing plates 2. Four-corner blocks 5 are fixedly connected to one end of each screw 4. Two threaded grooves 6 are formed on the surface of the drone body 1, achieving convenient disassembly of the support plates 3. This avoids the situation where, due to the fact that most devices on the market are fixed to the drone body 1, the support plates 3 become unusable after prolonged use due to surface damage or corrosion, requiring users to spend a lot of time disassembling and replacing them, or causing damage to the drone body 1 during replacement. This improves the usability of the device. A washer 7 is slidably connected to the arc surface of the screw 4. The size of the screw 4 matches the size of the washer 7. The cooperation between the screw 4, washer 7, and four-corner blocks 5 prevents workers from accidentally tightening the screw 4. When the surface of the fixing plate 2 comes into contact, it scratches the surface of the fixing plate 2. The arc surface of the screw 4 is slidably connected to the spring washer 8. The size of the screw 4 is adapted to the size of the spring washer 8. Through the cooperation of the spring washer 8, the screw 4 and the four corner blocks 5, the screw 4 is prevented from loosening due to vibration. Two rotating rods 9 are fixedly connected to the surface of the four corner blocks 5. The size of the screw 4 is adapted to the size of the thread groove 6. Through the cooperation of the rotating rods 9, the four corner blocks 5 and the screw 4, the operator can rotate the screw 4 without tools. The surface of the support plate 3 is fixedly connected to the rubber plate 10. The surface of the rubber plate 10 has several flat grooves 11. Through the cooperation of the support plate 3, the rubber plate 10 and the flat grooves 11, the landing impact force can be fully absorbed, protecting the UAV body 1 from damage caused by excessive impact force. The surface of the fixing plate 2 is coated with a corrosion-resistant coating 12. The corrosion-resistant coating 12 is an aluminum oxide coating. Through the cooperation of the fixing plate 2 and the corrosion-resistant coating 12, it has excellent corrosion resistance and wear resistance, extends the service life of the connector, and adapts to complex use environments.

[0022] Working principle: When the worker needs to disassemble the fixing plate 2, the worker rotates the two rotating rods 9. The rotating rods 9 drive the four corner blocks 5 to rotate, and the four corner blocks 5 drive the screw 4 to rotate. The screw 4 rotates inside the fixing plate 2 and rotates on the inner wall of the threaded groove 6. The screw 4 moves away from the inner wall of the threaded groove 6, and the washer 7 and spring washer 8 slide on the arc surface of the screw 4, so that the worker can complete the disassembly of the fixing plate 2.

[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
