Title:
INERTIAL MEASUREMENT MODULE AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/203992
Kind Code:
A1
Abstract:
Provided is an inertial measurement module (100), comprising a mounting bracket (10), a circuit board (20), a heat conduction element (30), and a cover plate (40) mounted on the mounting bracket (10); the circuit board (20) is mounted on an end face of the mounting bracket (10), and used for mounting the inertial measurement component (50) and the thermal conduction element (30); the inertial measurement component (50) comprises a thermal resistor (51) and an inertial measurement unit (52); the heat conduction element (30) is used for abutting against the thermal resistor (51) and the inertial measurement unit (52) such that the heat emitted by the thermal resistor is transferred to the inertial measurement unit (52); a first groove (41) is disposed on one surface of the cover plate (40), and the first groove (41) and a surface of the mounting bracket (10) form an accommodating space; the circuit board (20) and the heat conduction element (30) are both accommodated in the accommodating space, and the heat conduction element (30) and the bottom of the first groove (41) are arranged at a preset interval. Thus there is no contact between the cover plate (40) and the heat conduction element (30) and the heat conduction member (30) does not press against the inertial measurement unit (52), reducing or preventing the stress changes caused by temperature changes in the inertial measurement unit (52), increasing the accuracy and stability of flight control, and the invention is more convenient to use.
