Embodiment

[0019] Such as figure 1 The acceleration sensor structure shown includes a support base 1, an upper pole plate 4 and a lower pole plate 5 are fixed on the inner wall of the support base 1, and a movable pole plate 3 is arranged in the support base 1. Both ends of the movable pole plate 3 are fixed with elastic beams 2, the movable pole plate 3 is parallel to the upper pole plate 4, and the support seat 1 is provided with a force receiving hole 6 at the contact point with the elastic beam 2.

[0020] The upper pole plate 4, the lower pole plate 5 and the movable pole plate 3 are all connected to the signal processing circuit.

[0021] In order to facilitate the processing of the capacitance variation on the upper plate 4 and the lower plate 5 by the signal processing circuit, the upper plate 4 and the lower plate 5 are located on the same vertical plane.

[0022] In order to further improve the measurement accuracy, there are two upper pole plates 4 and two lower pole plates 5...

Abstract

The invention discloses an acceleration sensor structure. The structure comprises a supporting seat, wherein an upper polar plate and a lower polar plate are fixed on the inner wall of the supporting seat; a movable polar plate is arranged in the supporting seat; elastic beams are fixed at the two ends of the movable polar plate respectively; the movable polar plate is parallel to the upper polar plate; stress holes are formed in the contact part between the supporting seat and the elastic beams. The acceleration sensor structure has the advantages that the structure is simple, the manufacturing procedure is simple, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of microelectronics, and more specifically relates to an acceleration sensor structure. Background technique [0002] An accelerometer is an instrument for measuring the inertial acceleration of a carrier, and it is used in many ways. For example, the field of aerospace. Both inertial navigation and guidance are based on the accelerometer’s sensitive measurement of the carrier’s motion acceleration, so the performance of the accelerometer directly affects the stability of the measurement accuracy of the entire system and the final navigation accuracy. Existing accelerometers include support bodies, upper pole plates, lower pole plates, guide grooves, additional mass blocks, bases, etc., and their complex structures make the process of accelerometers cumbersome during processing and production, making processing costs and production costs higher. Contents of the invention [0003] The invention provides an acceler...
