Description

Technical Field

[0001] The utility model relates to the technical field of six-axis inertial sensors, in particular to a knock detection device based on the six-axis inertial sensor. Background Art

[0002] A six-axis inertial sensor is a device that can detect the motion state of an object in six degrees of freedom. This sensor is widely used in various fields, such as robotics, self-driving cars, aerospace, and the military, to achieve accurate and stable positioning and high-precision motion control. The principle of the six-axis inertial sensor is based on Newton's second law, using the force generated by the current in a specific magnetic field to measure the object's acceleration. These accelerations are converted into electrical signal output, so that the acceleration of the object in all directions can be calculated.

[0003] With the development of industrial automation, robotics, drones and other fields, sensors are being used more and more widely in these fields. In order to ensure that the sensors remain accurate and reliable within their normal service life, a knock detection device for a six-axis inertial sensor is needed to detect the six-axis inertial sensor. The existing knock detection device for a six-axis inertial sensor usually directly places the six-axis inertial sensor on a workbench for knock detection, and cannot guarantee that the six-axis inertial sensor will not move during the knock detection process, thereby reducing the accuracy of the six-axis inertial sensor detection. In addition, the existing knock detection device for a six-axis inertial sensor usually directly clamps and fixes the six-axis inertial sensor. This fixing method can easily cause damage to the six-axis inertial sensor during the clamping process, and cannot guarantee the integrity of the six-axis inertial sensor, thereby reducing the practicality of the device.
