Unmanned aerial vehicle for high-altitude holographic projection

Abstract

The invention relates to the technical field of unmanned aerial vehicle equipment, and discloses an unmanned aerial vehicle for high-altitude holographic projection. The unmanned aerial vehicle comprises a machine box, and four groups of brackets arranged at equal circumference are fixedly connected to the side surface of the machine box. A self-adjusting device and a telescopic sleeve are arranged; when the unmanned aerial vehicle tilts, if the unmanned aerial vehicle inclines leftwards (namely, the left is low and the right is high), a pointer is in a downward moving state relative to a right resistor strip; a resistor strip on the opposite left side is in an upward moving state; the current of a right electromagnet is increased; the current of a left-side electromagnet is reduced, namely, the repulsive force between the right electromagnet and the right permanent magnet is increased; the repulsive force between the left electromagnet and the left permanent magnet is reduced; therefore, the right side supporting rod moves downwards under the action of a reset spring; when a left supporting rod moves upwards and the heights of the left supporting rod and the right supporting rod are the same, the projector is in a vertical stable state, the projection effect of the projector is improved, the pointer returns to the middle of the resistor strips on the two sides, the electromagnets on the two sides have the same current, and the heights of the two sides do not change any more.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle for high-altitude holographic projection. Background technique [0002] Unmanned aerial vehicle, referred to as "unmanned aerial vehicle" ("UAV"), is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. Therefore, people apply UAVs to various fields, including a UAV for high-altitude holographic projection. [0003] However, the existing unmanned aerial vehicle for high-altitude holographic projection also has the following problems in actual use: first, because this type of unmanned aerial vehicle performs projection work at high altitude, the unmanned aerial vehicle is affected by the external environment in the air, External factors such as airflow and natural wind will affect the stability of the drone, causing the drone to shift or tilt during projection, affecting the projec...

Problems solved by technology

[0003] However, the existing unmanned aerial vehicle for high-altitude holographic projection also has the following problems in actual use: first, because this type of unmanned aerial vehicle performs projection work at high altitude, the unmanned aerial vehicle is affected by the external environment in the air, External factors such as airflow and natural wind will affect the stability of the drone, causing the drone to shift or tilt during projection, affecting the projection effect, and the drone is affected by its own driving device, motor and other equipment There will also be shaking and tilting, which will affect the projection effect and affect people's viewing effect; secondly, when the UAV carries the holographic projection device, it will increase its own weight virtually, causing the UAV to land after finishing the projection work. When the UAV and the ground collide with each other, the damage to the UAV is increased, and the damage to the landing gear of the UAV is often the largest. Therefore, it is urgent to design a UAV with stable high-altitude holographic projection.
