Title:
INERTIAL MEASUREMENT MODULE, SHOCK ABSORPTION SYSTEM, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/203991
Kind Code:
A1
Abstract:
Provided is an inertial measurement module (100), relating to the technical field of unmanned aerial vehicles, and comprising a mounting bracket (10), a circuit board (20), an inertial measurement component (30), a heat conduction element (40), and a counterweight component (50); the circuit board (20) is mounted on a surface of the mounting bracket (10), and the inertial measurement component (30) and the heat conduction element (40) are mounted in sequence, the inertial measurement component (30) comprising a thermal resistor (31) and an inertial measurement unit (32); the heat conduction element (40) is used for abutting against the thermal resistor (31) and the inertial measurement unit (32) such that the heat emitted by the thermal resistor (31) is transferred to the inertial measurement unit (32); the counterweight component (50) is mounted on a surface of the mounting bracket (10), and a first groove (511) is disposed on one end surface facing the mounting bracket (10) to form an accommodating space with one end surface of the mounting bracket (10); the heat conduction element (40) and the inertial measurement component (30) are both accommodated in the accommodating space, the heat conduction member (40) and the bottom of the first groove (511) being arranged at a preset interval. Thus the heat conduction member (40) and the inertial measurement unit (32) do not press against each other, reducing the stress changes caused by temperature changes in the inertial measurement unit (32), increasing the accuracy and stability of flight control.
