Abstract

The invention provides an unmanned aerial vehicle. The unmanned aerial vehicle comprises a vehicle body (1), an inertial measurement unit (2) arranged in the vehicle body (1), a mounting rack (3) for fixing the inertial measurement unit (2), and a circuit board (4) which is fixedly arranged in the vehicle body (1) and is integrated with multiple functional modules, the inertial measurement unit (2) is mounted on the circuit board (4) through the mounting rack (3); the mounting frame (3) comprises a first bracket and a second bracket, the first bracket is positioned on the circuit board (4), the second bracket is arranged on one side, far away from the circuit board (4), of the first bracket, and the inertial measurement unit (2) is fixed on one side, far away from the first bracket, of the second bracket. The mounting rack for fixing the inertial measurement unit is mounted on the circuit board in the fuselage, so that no additional space structure needs to be designed for mounting the mounting rack; the double-layer support can reduce the influence of machine body vibration on the inertial measurement unit, can separate the inertial measurement unit from the circuit board, and reduces the interference between the inertial measurement unit and components on the circuit board.

Description

technical field [0001] The present application relates to the field of aircraft, in particular to an unmanned aerial vehicle. Background technique [0002] The inertial measurement unit (IMU, English full name: Inertial measurement unit) is an important device for measuring the attitude of the UAV. It needs to be firmly installed on the UAV to improve the reliability of the UAV attitude measurement. [0003] At present, the inertial measurement unit of most UAVs is fixed on the inner shell of the UAV's fuselage through the mounting bracket, and another space structure needs to be designed separately on the inner shell of the fuselage to fix the mounting frame, so as to fix the inertial measurement unit. unit. However, since the usable space inside the fuselage is basically occupied by PCB (Printed Circuit Board, printed circuit board) of various functional modules, it also forms a certain obstacle to the installation of the inertial measurement unit, and also makes the abov...
