The present invention relates to an inertial measurement device and a mechanical device, the inertial measurement device includes a PCB board and an inertial measurement unit, the PCB board includes a PCB main body, and a slot is formed from one side of the PCB board and connected to the The main part of the PCB is fixedly connected to the isolation part, and the inertial measurement unit is arranged on the isolation part. The present invention reduces or even eliminates the mechanical stress transmitted to the inertial measurement structure by optimizing the PCB board design of the inertial measurement structure, so that the mechanical stress has little influence on the inertial measurement units in the inertial measurement structure, such as gyroscopes and accelerometers. Thereby reducing noise and zero bias, which is conducive to the best performance of gyroscopes and accelerometers, thereby improving the control accuracy of inertial measurement structures, especially suitable for applications such as gimbals, robots, unmanned aerial vehicles or manned aircraft, etc. equipment or field.
Description
technical field [0001] The present invention relates to the improvement of inertial measurement related equipment, in particular to inertial measurement device and mechanical equipment. Background technique [0002] UAV technology is developing rapidly. At present, the IMU (inertial measurement unit) board of the drone industry's aerial photography stabilization gimbal is usually fixed by locking screws. Specifically, the IMU inertial measurement unit of the gimbal is mainly composed of gyroscopes. , an accelerometer and a main control MCU (Microcontroller Unit, micro control unit), the gyroscope detects the angular velocity, the accelerometer detects the acceleration, and feeds back the angular velocity and acceleration information to the MCU through the serial interface, and the MCU performs further algorithm processing to control the cloud. The motors of the three axes of the platform make corresponding motion compensation, so as to realize the stability control of the pl...
