Description

Technical Field

[0001] The utility model relates to the technical field of flight anti-collision, in particular to a flight anti-collision device for a drone. Background Art

[0002] Unmanned aerial vehicles, referred to as "drones", are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or operated completely or intermittently autonomously by on-board computers. In the early stages of drone development, there are batch flight test functions, so they need to be equipped with corresponding anti-collision devices, which can reduce the cost of research and development to a certain extent.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing UAV flight anti-collision device cannot be designed to be disassembled and assembled, and there is a need for research and development to test multiple UAVs in flight, so each group of UAVs needs to be equipped with an anti-collision device, and the investment cost increases accordingly. Some of the devices with disassembly functions have a low degree of intelligence and are inconvenient to disassemble and assemble, and are in urgent need of improvement. Therefore, we propose a UAV flight anti-collision device. Utility Model Content

[0009] A mounting seat is sleeved on the top of the support pole, and the clamping block is clamped in a preset slot in the mounting seat, and the mounting seat is integrally formed and fixed on the bottom of the drone body;

[0010] A groove is provided on the rear side of the support pole, in which an infrared sensor and a processor are fixedly installed, which can be used in conjunction with components such as an electromagnet, a mounting seat and a card block. During the use of the UAV flight anti-collision device, whenever a new UAV is replaced for testing, the support pole can be held with one hand, the UAV can be held with one hand, and the electromagnet can be turned on with a finger. The electromagnet is energized and temporarily absorbs the positioning iron block, so that the card block shrinks and disengages from the slot, and a new UAV mounting seat is set on the support pole. Subsequently, the electromagnet is closed, and the force of the tension spring drives the card block to move outward and extend into the slot, so that the UAV and the anti-collision mechanism can be detachably assembled, and the replacement use greatly reduces the anti-collision investment cost, and the limiting structure is easy to disassemble and assemble.

It can be used in conjunction with components such as the infrared sensor and the processor. Whenever the support pole is held, the infrared sensor can detect the human hand, which means that the drone is to be replaced. The processor issues a command and the electromagnet is turned on. After it is plugged in place, the anti-collision device is placed on the ground or other planes, and the processor issues a command to turn off the electromagnet, making the anti-collision device highly intelligent, avoiding frequent opening and closing of the electromagnet, and avoiding unnecessary trouble caused by forgetting to turn off the electromagnet.
