Abstract

An unmanned aerial vehicle rotor anti-collision support foot, comprising a machine arm (1), one end of the machine arm (1) being rotatably connected to a connection block (2), the end of the connection block (2) away from the connection to the machine arm (1) being provided with a concave cavity (20), two anti-collision rods (200) being rotatably connected within the concave cavity (20), each anti-collision rod (200) comprising a horizontal connection section (201) connected to the concave cavity (20) and a flexible anti-collision needle (202) obliquely connected to the connection section (201). The foot also comprises a limiting block (3), the limiting block (3) being used for performing limiting when the two anti-collision rods (200) are spread out. During use, the connection block (2) is rotated, the two anti-collision rods (200) are separated by a certain angle, and the limiting block (3) and the connection block (2) lock and fix the anti-collision rods (200), so that the anti-collision rods (200) are fixedly distributed on two sides of the outside of a rotor, and the rotor is protected from being impacted and damaged when a machine body turns or rolls. The whole structure is simple and costs are low.

Description

Unmanned aerial vehicle rotor anti-collision foot

Technical field

The invention relates to the technical field of drones, and more particularly to a rotor anti-collision foot of a drone.

Background technique

UAVs are unmanned aircraft operated by radio remote control equipment and self-provided program control devices. Civil drones have important applications in aerial photography, agriculture, plant protection, disaster relief, etc. Most of the UAV rotors currently used are not. Set protection, when rolling off and landing, once the rollover occurs, it is easy to damage the rotor that is rotating at high speed.

technical problem

The technical problem to be solved by the present invention is to provide a UAV anti-collision foot with good rotor protection effect against the above-mentioned defects of the prior art.

Technical solution

The technical solution adopted by the present invention to solve the technical problem thereof is:

Constructing a UAV anti-collision foot, comprising a machine arm; wherein, one end of the arm is rotatably connected with a connecting block, and a connecting cavity is provided at one end of the connecting block away from the arm, and the cavity rotates Two anti-collision bars are connected, the anti-collision bar includes a horizontal connecting section connected to the cavity and an elastic anti-collision pin obliquely connected to the connecting section; and a limiting block, the limiting block is used The limit is performed when the two anti-collision bars are deployed.

In the unmanned aerial vehicle rotor anti-collision leg of the present invention, one end of the limiting block is rotatably connected to the connecting block, and the other end is fixedly connected to the connecting block by a screw.

In the unmanned aerial vehicle rotor anti-collision leg of the present invention, the two sides of the limiting block are provided with grooves matching the shape of the anti-collision bar.

In the unmanned aerial vehicle rotor anti-collision leg of the present invention, the anti-collision needle end portion is fixedly provided with a plastic buffering member.

Beneficial effect

The utility model has the beneficial effects that: in use, when the connecting block is rotated and the two anti-collision bars are separated by a certain angle, the limiting block and the connecting block are locked and fixed to the anti-collision bar, so that the anti-collision bar is fixedly distributed on the outer sides of the rotor Protect the rotor from impact and damage when the fuselage is dumped or rolled; the overall structure is simple and the cost is low.

DRAWINGS

In order to more clearly illustrate the embodiments of the present invention or the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments. For ordinary technicians, other drawings can be obtained based on these drawings without any creative work:
