Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

The embodiment of the application provides a foot rest, the foot rest can be used for unmanned aerial vehicle, unmanned aerial vehicle can be used in each field of production, life, especially uses in aspects such as agricultural plant protection, aerial photography, patrolling and examining, survey and drawing, investigation. The foot rest can connect in unmanned aerial vehicle's fuselage bottom supports the fuselage. Specifically, the foot rest may include, but is not limited to, any one of a fixed foot rest and a foldable foot rest, and the embodiment of the present application is described by taking the fixed foot rest as an example, and other types of foot rests may be implemented by reference.

Referring to fig. 1, a schematic structural diagram of a foot rest according to an embodiment of the present application is shown, referring to fig. 2, an exploded schematic structural diagram of the foot rest shown in fig. 1 is shown, referring to fig. 3, a schematic sectional structural diagram of a position a of the foot rest shown in fig. 1 is shown, and referring to fig. 4, a schematic structural diagram of a position B of the foot rest shown in fig. 3 is shown, where the foot rest specifically includes:

the supporting rods 10 are multiple, the first ends of the supporting rods 10 are fixedly connected with the unmanned aerial vehicle body, and the second ends of the supporting rods 10 extend in the direction far away from the unmanned aerial vehicle body; and
