Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), in particular to an anti-collision UAV. Background Art

[0002] A drone, short for unmanned aerial vehicle (UAV), also known as a drone, is an unmanned aircraft controlled by a radio remote control device or a self-contained programmable controller. With the continuous development of technology, drones have gained widespread use in a variety of fields, including aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television production, and creating romantic moments.

[0003] A search of patent application number CN202020787347.6 discloses a drone comprising a fuselage, an arm assembly, and a rotor power assembly. The fuselage comprises a housing with an internal accommodating cavity, the arm assembly is rotatably connected to an arm hinge formed on the wall of the housing, and the rotor power assembly is disposed on the arm assembly. The drone described in this utility model has a lightweight structure, which can improve the drone's carrying capacity, avoid increasing the drone's waste weight, improve the carrying capacity, and extend the flight time. The foldable structure effectively reduces the occupied volume, has high space utilization, is convenient for storage, and is conducive to transportation.

[0004] However, this patent still has some shortcomings. The drone lacks an anti-collision protection structure, and during flight, the drone often collides with other objects due to external factors and operational problems. At this time, the rotor power assembly directly collides with other objects, causing damage to the propeller, which needs to be replaced and repaired, greatly increasing the cost of using the drone. At the same time, this patent does not have a landing buffer component. Since the drone is equipped with a chip motherboard, it is often equipped with precision components such as cameras according to usage needs. The impact force during landing is too large, which can easily cause damage to the precision components.

[0005] To this end, we propose a collision-avoidance UAV. Utility Model Content

[0022] An extrusion plate 12 is slidably connected to the oil storage seat 11. A plurality of overflow holes 14 are provided on the extrusion plate 12. The plurality of overflow holes 14 facilitate the extrusion plate 12 to extrude the damping oil. A plurality of second springs 13 are fixedly installed on the extrusion plate 12 on the outside of the overflow holes 14. The tops of the plurality of second springs 13 are fixedly installed on the top of the oil storage seat 11. The second springs 13 can drive the extrusion plate 12 to reset. A plurality of support rods 16 are fixedly installed on the bottom end of the extrusion plate 12. Two rubber support columns 15 are provided at the bottom of the oil storage seat 11. The bottom ends of the plurality of support rods 16 are respectively It is fixedly mounted on the corresponding rubber support column 15, and the rubber support column 15 can provide preliminary buffering when the drone body 1 lands. One side of each first spring 6 is fixedly mounted on the buffer block 5, and the side of each first spring 6 away from the buffer block 5 is fixedly mounted on the inner wall of the mounting groove 4.

Multiple protective frames 10 are all arranged in a C-shape, which is beneficial to the use of this equipment.

[0023] Working principle: When in use, an appropriate amount of damping oil can be added to the oil storage seat 11. When the drone body 1 collides with other objects during flight, the arc-shaped buffer pad 9 and the protective frame 10 slide toward the side of the drone body 1, so that the buffer block 5 compresses the first spring 6, and then the first spring 6 cooperates with the damper 7 to buffer and eliminate vibration, and then the buffer block 5 drives the protective frame 10 to reset, which can provide buffering protection for the propeller 3 and avoid damage caused by direct contact between the propeller 3 and the colliding object. During the landing process, the two rubber support columns 15 will land first, and the rubber support columns 15 will undergo a certain deformation and rebound to perform preliminary shock absorption. The squeezed rubber support columns 15 will drive multiple support rods 16 to push the squeezed rubber support columns 15 upward. The pressure plate 12 and the extrusion plate 12 compress the second spring 13 and squeeze the damping oil, so that the damping oil enters the oil storage seat 11 through the overflow hole 14 and is located below the extrusion plate 12 to consume the vibration potential energy. Then the second spring 13 drives the extrusion plate 12 to return, so that the drone body 1 lands smoothly on the ground. This anti-collision drone is easy to use. Through the above components, it can play an anti-collision protection role for multiple propellers 3 during flight, avoiding direct contact between the propeller 3 and the collision object in the event of a collision and causing damage, thereby greatly reducing the use cost of this drone. At the same time, it can perform buffering and shock absorption when this drone lands, avoiding damage to precision components such as the camera inside the drone body 1 due to vibration impact.
