Inertia measuring module of unmanned aircraft

Abstract

The invention relates to an inertia measuring module of an unmanned aircraft. The inertia measuring module comprises a housing assembly, a sensing assembly and a vibration damper, wherein the vibration damper comprises a first vibration damping pad; the sensing assembly comprises a first circuit board, a second circuit board, and a flexible signal line connecting the first circuit board and the second circuit board; an inertia sensor is fixed on the second circuit board; the first circuit board is fixed on the housing assembly; the unmanned aircraft inertia measuring module also comprises a weight gain block, and the integral body formed by orderly bonding the second circuit board, the weight gain block, the first vibration damping pad and the first circuit board is clamped in the housing assembly. According to the invention, components such as the inertia sensor and the like which have high requirements for vibration performance are integrated on the second circuit board; by setting the first vibration damping pad, the vibration suffered by the inertia sensor is attenuated to below 30% of the vibration when no vibration damping pad is used; the influence on the inertia sensor caused by the working vibration frequency of the unmanned aircraft is greatly reduced; and the stability of the inertia sensor measurement is improved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle control, in particular to an unmanned aerial vehicle inertial measurement module. Background technique [0002] In the prior art, the vibration reduction measure for the inertial measurement module of the unmanned aerial vehicle is to lay four vibration damping pads outside the casing of the control module to form four fulcrums to support the outer casing of the entire control module. The vibration-damping pad is arranged outside the inertial measurement module of the unmanned aerial vehicle. This structure has the following defects: (1) The vibration-damping pad needs to be installed on a platform, which leads to an increase in the volume and weight of the entire control module, thereby increasing the aircraft's ineffectiveness. (2) The vibration damping pad is exposed, which will lead to the probability of damage to the vibration damping pad, thereby affecting the service life of the inert...
