Embodiment 1

[0030] figure 1 A structural schematic diagram of a motion sensor installation device provided by an embodiment of the present invention; please refer to figure 1 , this embodiment provides a motion sensor installation device, including a mounting frame 1000 and a plurality of vibration-damping mechanisms 2000 . In the illustrated embodiment, the motion sensor is described using an IMU as an example.

[0031] The mounting frame 1000 is used for carrying the motion sensor 3000 . A plurality of vibration damping mechanisms 2000 are connected to the installation frame 1000 and are used for damping the vibration of the installation frame 1000 .

[0032] Wherein, a plurality of damping mechanisms 2000 are arranged at intervals, and each damping mechanism 2000 includes an elastic member 2100 , and the elastic member 2100 abuts against the mounting frame 1000 to damp the mounting frame 1000 .

[0033] Specifically, the mounting frame 1000 can be made of plastic or other low-densit...

Embodiment 2

[0039] figure 2 The second structural schematic diagram of the installation device of the motion sensor provided by the embodiment of the present invention; please refer to figure 2 As shown, on the basis of the first embodiment above, further, the elastic member 2100 can be disposed under the installation frame 1000 , and the installation frame 1000 can press the elastic member 2100 to cause the elastic member 2100 to compress and deform.

[0040] In this embodiment, the mounting frame 1000 can be pressed on the carrier frame below the aircraft fuselage 4000 by the elastic member 2100, the elastic member 2100; the vibration transmitted from the aircraft fuselage 4000 to the mounting frame 1000 can be buffered by the compression deformation of the elastic member 2100 , so as to realize the vibration reduction of the installation frame 1000, and further realize the vibration reduction of the motion sensor 3000, which is helpful to improve the measurement accuracy of the motion ...

Embodiment 3

[0044] On the basis of the first embodiment above, further, the elastic member 2100 may also be arranged above the installation frame 1000 , and the installation frame 1000 can pull the elastic member 2100 to cause the elastic member 2100 to be stretched and deformed.

[0045] In this embodiment, the mounting frame 1000 can be suspended under the carrier frame of the aircraft fuselage through the elastic member 2100, and the elastic member 2100 can buffer the vibration transmitted from the aircraft fuselage to the mounting frame 1000 through the tensile deformation of the elastic member 2100, thereby realizing The vibration reduction of the installation frame 1000 , and thus the vibration reduction of the motion sensor 3000 , helps to improve the measurement accuracy of the motion sensor 3000 .

[0046] Among them, terms such as "upper" and "lower" are used to describe the relative positional relationship of each structure in the drawings, which are only for the convenience of ...

Abstract

A motion sensor installation device, comprising: a mounting frame (1000), used to carry a motion sensor (3000); ) for vibration damping; wherein, a plurality of vibration damping mechanisms (2000) are arranged at intervals, and each vibration damping mechanism (2000) includes an elastic member (2100), and the elastic member (2100) abuts against the mounting frame (1000) to The mounting frame (1000) is used for vibration reduction; the motion sensor (3000) is installed through the mounting frame (1000), and the elastic member (2100) is abutted with the mounting frame (1000), so that the elastic member (2100) is in contact with the mounting frame (1000) ) closely against each other, if the vibration damping effect needs to be adjusted, then part or all of the vibration damping mechanism (2000) can be adjusted respectively, so that it is easier for the vibration damping mechanism (2000) to adjust the vibration damping effect without affecting Reliability of connection between the vibration damping mechanism (2000) and the installation frame (1000).

Description

technical field [0001] The invention relates to a motion sensor installation technology, in particular to a motion sensor installation device and an unmanned aerial vehicle. Background technique [0002] Motion sensor is a commonly used detection instrument, which has certain applications in many industries. With the continuous development of technology, there are more and more types of motion sensors. The commonly used motion sensors mainly include acceleration sensors, gyroscopes, geomagnetic sensors, and inertial measurement units (IMUs). Accelerometer and gyroscope; among them, the accelerometer is used to detect the acceleration component of the object, and the gyroscope is used to detect the angle information of the object; generally the IMU is installed at the center of gravity of the object. Due to its ability to measure the three-axis attitude angle (or angular rate) and acceleration of an object, the IMU is usually used as the core component of navigation and guid...
