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.

    本发明涉及无人机设备技术领域,且公开了一种高空全息投影用无人机,包括机盒,所述机盒侧面固定连接有等圆周排列的四组支架。通过自调节装置和伸缩套的设置,当无人机发生倾斜时,若无人机向左侧倾斜(即左低右高),指针相对右侧电阻条为下移状态,相对左侧电阻条为上移状态,因此右侧电磁铁电流增大,左侧电磁铁电流减小,即右侧电磁铁与右侧永磁体排斥力增大,左侧电磁铁与左侧永磁体排斥力减小,导致右侧支撑杆在复位弹簧的作用下下移,左侧支撑杆上移,当移动到两侧支撑杆高度相同时,即投影仪处于竖直稳定状态,有利于提高投影仪投影效果,此时指针恢复到位于两侧电阻条中部位置,两侧电磁铁所通电流相同,两侧高度不再变化。
