Description

Technical Field

[0001] The utility model provides a core positioning device, belongs to the technical field of quartz flexible accelerometer equipment, and particularly relates to a core positioning device for a quartz accelerometer. Background Art

[0002] A quartz accelerometer is a device that uses the properties of quartz crystals to detect acceleration. It works based on the piezoelectric effect, which is when pressure is applied or deformation is caused, quartz crystals generate electric charges. When a quartz crystal is subjected to acceleration, it causes a small deformation of the crystal, which generates charge signals. These signals can be measured and used to determine the magnitude of the acceleration.

[0003] After a quartz accelerometer makes a measurement, the quartz movement must be reset, which ensures that the quartz crystal can receive the acceleration signal at the correct position when measuring acceleration, thereby avoiding measurement errors. Various mechanical structures such as springs and limit devices are usually used to assist in resetting the quartz movement, but the introduction of other structures will increase the size of the device, making the installation of the quartz accelerometer inconvenient.
