Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and specifically to a multi-mode unmanned aerial vehicle. Background Art

[0002] An unmanned aerial vehicle generally refers to an unpiloted aircraft, which is operated by a control station (remote control, computer or autopilot). Unmanned aerial vehicles can be used for various purposes, including sterile control detection, bioburden detection, etc. Please be sure to carefully check important information. An unpiloted aircraft is abbreviated as "unmanned aerial vehicle", and its English abbreviation is "UAV". It is an unpiloted aircraft that is controlled by a radio remote control device and a self-provided program control device, or is completely or intermittently autonomously operated by an on-board computer. Compared with piloted aircraft, unmanned aerial vehicles are often more suitable for tasks that are too "stupid, dirty or dangerous". Unmanned aerial vehicles can be divided into military and civilian according to the application field. In the military aspect, unmanned aerial vehicles are divided into reconnaissance aircraft and target drones. In the civilian aspect, the combination of unmanned aerial vehicles and industrial applications is the real demand for unmanned aerial vehicles; their applications in fields such as aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, observing wild animals, monitoring infectious diseases, mapping, news reporting, power line inspection, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the uses of unmanned aerial vehicles themselves. Developed countries are also actively expanding industrial applications and developing unmanned aerial vehicle technology; When the unmanned aerial vehicle is descending, it is unable to protect the lower part of the unmanned aerial vehicle, resulting in the unmanned aerial vehicle being prone to tipping over or directly contacting the ground during the descent process, causing damage to the unmanned aerial vehicle, increasing the use cost of the unmanned aerial vehicle. At the same time, the camera is usually connected to the unmanned aerial vehicle in a snap-fit manner, making it prone to falling off due to external factors, thus reducing the stability of the camera installation. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides a multi-mode drone. By means of an air inlet pipe, external air can enter the interior of the hollow box, and part of the air inside the hollow box can enter the interior of the buffer airbag. Affected by the inflation of the air, the buffer airbag can expand. By using the expansion of the buffer airbag, the diameter of the buffer airbag can be changed. The connecting plate can drive the movable protective baffle to move together under the influence of the expansion of the buffer airbag, so that the connection between the connecting plate and the movable protective baffle can be separated from the lower surface of the fuselage. The movable protective baffle is made of plastic. When the drone descends continuously, the movable protective baffle can swing upward around the connecting plate under the influence of wind to protect the front and rear surfaces of the fuselage. The buffer airbag inside the buffer airbag can reduce the impact when the drone descends. Combined with the protection of the movable protective baffle, it can prevent damage to the drone during the descent process. When the drone is flying, the electric push rod is electrically connected to an external control terminal. Starting the electric push rod can push the limit moving frame to move up and down. When the limit moving frame moves up and down, the limit moving frame can drive the wiping adsorption cotton to move together. By using the wiping adsorption cotton, the water stains and dust on the surface of the sealed placement box can be wiped, thereby improving the clarity of the camera during shooting. By sliding the bottom plate, it can expand the bottom plate outward to adjust between the bottom plates. When the bottom plate expands, the support plate can be used to push the telescopic rod to squeeze the spring, so that the bottom plate can limit the lower surface of the camera, and the rubber seat can limit the upper surface of the camera. By using the elasticity of the spring, when it is not affected by external extrusion, the spring can drive the telescopic rod to push the support plate to move in the reverse direction, thereby clamping and fixing the camera. The fixing rod passes through the interior of the hollow rod and the telescopic rod to fix the telescopic rod. The sealed placement box can waterproof the camera and other advantages.
