The invention relates to the technical field of unmanned aerial vehicle calibration, and discloses an automatic horizontal calibration device for unmanned aerial vehicle landing. The calibration device comprises a box body, a horizontal plate and a placement plate, and is characterized in that the interior of the box body is fixedly connected with a transverse plate, the bottom of the transverse plate is rotatably connected with a balancing weight, and the inner top wall of the box body is fixedly connected with a telescopic rod; and a pressing plate is fixedly connected to the bottom of the telescopic rod, two fixing columns are fixedly connected to the bottom of the pressing plate, ejector rods are inserted into the two fixing columns, two extrusion springs are fixedly connected to the inner bottom wall of the box body, and a reference plate is movably connected to the tops of the two extrusion springs. The bottom of the balancing weight is kept in a horizontal state under the effectof gravity, then the pressing plate drives the ejector rods to downwards eject and fix the top of the balancing weight, the reference plate is tightly attached to the bottom of the balancing weight under the effect of the extrusion springs, and then the horizontal plate and the placement plate are kept in a horizontal state; and therefore, the effect that the placement plate can be kept in a horizontal state when the device is located on the uneven ground is achieved.

    本发明涉及无人机校准技术领域,且公开了一种无人机降落自动水平校准装置,包括箱体、水平板和放置板,所述箱体的内部固定连接有横板,所述横板的底部转动连接有配重块,所述箱体的内顶壁固定连接有伸缩杆,所述伸缩杆的底部固定连接有压板,所述压板的底部固定连接有两个固定柱,两个所述固定柱的内部均插接有顶杆,所述箱体的内底壁固定连接有两个挤压弹簧,两个所述挤压弹簧的顶部活动连接有基准板。通过配重块在重力的作用底部保持水平状态,然后通过压板带动顶杆向下将配重块的顶部顶住固定,基准板在挤压弹簧的作用下紧贴配重块的底部,进而使水平板和放置板保持水平状态,从而达到了该装置在不平整的地面时放置板也能保持水平状态的效果。
