Unmanned aerial vehicle protection underframe

Abstract

The invention discloses an unmanned aerial vehicle protection underframe. The unmanned aerial vehicle protection underframe comprises an unmanned aerial vehicle body, wherein a protection revolving shaft is arranged between support frames; the two ends of the protection revolving shaft are wound with a torsional spring; the two sides of the torsional spring are connected with two protection plates respectively; the lower ends of the support frames are provided with trigger grooves; the bottom end of a movable rod is fixedly connected through the underframe; a carrier rod is fixedly arranged at the upper end of the middle part of the underframe; a revolving shaft is fixedly arranged on the middle part of the open end of a mounting groove; the two sides of the revolving shaft are in movable sleeve connection with clamping blocks; the upper ends of the clamping blocks are fixedly connected with limit springs; the upper ends of the limit springs are fixedly connected with push rods. In the structure of the unmanned aerial vehicle protection underframe, an electromagnet block is closed through a controller when an unmanned aerial vehicle lands, so that a magnet sheet and the electromagnet block lose repulsive force, and a locking rod moves upwards; the movable rod moves upwards under the action of gravity when the unmanned aerial vehicle lands in order to drive and trigger the carrier rod to move upwards, so that the upper end of the protection plate is separated from the clamping blocks, and the protection plate is opened and supported on the ground under the action of the torsional spring, thereby increasing contact area between the unmanned aerial vehicle underframe and the ground.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a protective chassis for drones. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment or onboard computer program control system. UAV has simple structure and low cost of use. It can not only complete the tasks performed by manned aircraft, but also is suitable for manned aircraft. It plays a very important role in emergency response and early warning of emergencies. At the same time, with the advancement of science, more civilian drones have been developed, and a large number of drones are used in the field of aerial photography. The aerial photography of drones has the advantages of high definition, large scale, small area, and high potentiality, and is especially suitable for obtaining Aerial images of belt-shaped areas, and drones provide convenient operation for aerial photography. [0003] The bottom of the current drones w...

Problems solved by technology

[0003] The bottom of the current drones will be equipped with a chassis for protection when the drone takes off and lands, and the support is convenient for the drone to take off, but the traditional drone chassis is a simple support frame structure. Man-machines are usually unstable when they land, and it is easy to overturn the drone, resulting in damage to the drone. For this reason, we propose a protective chassis for drones to solve the above problems
