Horizontal landing system for multi-rotor unmanned aerial vehicles

The invention relates to the technical field of multi-rotor unmanned aerial vehicles, in particular to a horizontal landing system for multi-rotor unmanned aerial vehicles. The horizontal landing system comprises adaptive adjusting units. The adaptive adjusting units are arranged at the lower end of a landing gear at intervals, and slide terminals are slidably arranged in the adaptive adjusting units in the up-down directions. The horizontal landing system for the multi-rotor unmanned aerial vehicles has the advantages that the various slide terminals can be in contact with pavements under theeffect of the gravity and can be rearranged in the up-down directions when the fact that the distances from the landing gear to the ground are smaller than or equal to set values is detected by distance sensor modules, the various rearranged slide terminals are matched with concave-convex locations on the pavements in a one-to-one correspondence manner, detection signals can be transmitted to control modules by the dista
