Description

Technical Field

[0001] This utility model relates to the field of accelerometer technology, and in particular to a high-stability quartz flexible accelerometer pendulum component. Background Technology

[0002] Quartz flexible accelerometers are key components in inertial systems. Due to their high accuracy, high reliability, and low power consumption, they are widely used in high-precision systems such as inertial navigation, attitude control, platform stabilization, missile servos, and drilling control. In recent years, with the development of high-precision weaponry, many fields have placed higher demands on accelerometers, requiring not only high stability, repeatability, low power consumption, and fast start-up, but also strong resistance to vibration and shock, and high reliability.

[0003] A search revealed Chinese Patent Publication No. CN201920337296.4, which includes a main body covered by a shell. A sealing device is fixedly connected to the top of the shell. The sealing device includes a sealing ring, a sealing ring, and a water-absorbing sheet. The bottom of the sealing ring is fixedly connected to the inner cavity of an annular groove, and both sides of the sealing ring are fixedly connected to the inner cavity of a third groove. This utility model, through the combined use of a first yoke, a second yoke, thermal paste, an integrated circuit board, a first groove, a magnet, a magnetic cap, a second groove, a flexible ring, and a coil, can better measure acceleration and ensure the accuracy of the measurement. The combined use of the annular groove, through hole, third groove, sealing ring, sealing ring, and water-absorbing sheet can better seal the device, enabling it to adapt to harsh working environments, extending its service life, and better ensuring the measurement work. However, the pin structure in this application is exposed externally, lacking effective protection. This makes it easy to damage the device's structure before installation, resulting in wear and tear and preventing normal installation and use. Utility Model Content
