Supporting and protection mechanism of four-rotor robot

Abstract

The invention discloses a supporting and protection mechanism of a four-rotor robot, which comprises a rotor supporting rack and a gyro protection mechanism, wherein the rotor supporting rack consists of a base, rotor and rotor driving motor fixing seats, and a long shaft and a short shaft which are used for mounting rotors and rotor driving devices; the gyro protection mechanism consists of a gyro mechanism and flexible levers; the gyro mechanism consists of an outer ring, a middle ring, two flexible lever fixing seats, an inner ring and shaft sleeves; the two ends of the long shaft of the rotor supporting rack are connected with the two shaft sleeves on the inner ring of the gyro protection mechanism to form a rotating shaft; and the rotor supporting rack freely rotates around the gyro protection mechanism. According to the supporting and protection mechanism, the robot can adapt to an unpredictable external environment, can effectively cope with an external emergency situation in a flying process, and can still keep an inherent state in case of collision. The supporting and protection mechanism is simple to manufacture, low in cost, good in adaptability and wide in application scope.

Description

technical field [0001] The invention relates to the field of robots, in particular to a support and protection mechanism for a four-rotor robot. Background technique [0002] In recent years, multi-rotor-based UAVs and flying robots have developed rapidly. They can be used in military reconnaissance, environmental detection, aerial photography, etc. They have high application value and broad market prospects. But most of these drones and robots are basically unprotected or simply add a plastic stopper to the side of the rotor to protect the rotor. As the carrier of applications such as military reconnaissance, environmental detection, and aerial photography, the working environment of such drones and flying robots is unknown, complex and changeable, so protective facilities are essential.

Problems solved by technology

Chinese utility model patent CN203680323U discloses a general-purpose multi-rotor robot backbone support safety protection system, which can provide support and protection for multi-rotor robots, but the biggest deficiency is that when the robot is impacted by the outside world, the protection system cannot keep the robot The original flying state will cause the robot to roll and other actions driven by the protection system, which may cause the robot to lose balance or even fall
