Posture control device

Abstract

The invention discloses a posture control device. The device comprises a supporting frame; the supporting frame comprises more than two spring seats which are arranged in the vertical direction; more than two springs, which are manufactured through two-way memory alloy, are vertically arranged between every two adjacent spring seats; the upper end and the lower end of each spring are respectively fixedly connected to every two adjacent upper and lower spring seats; every two adjacent spring seats are integrally connected through a universal coupling; the upper end and the lower end of each universal coupling are respectively fixedly connected to the upper and lower spring seats. The posture control device has the advantages of being large in driving force, simple in structure, recyclable, high in reliability, capable of working for a long time, being small in cost, small in noise, and convenient to mount; in addition, the outstanding performances of biological posture control and the concise and compact structure are brought; the two-way memory alloy springs are high in flexibility and can ensure the impact resistance of the posture control device.

Description

technical field [0001] The invention relates to an attitude control device. Background technique [0002] In the field of attitude control technology, at present, most of the drive methods for attitude control devices at home and abroad are gunpowder drive, electromagnetic drive or motor drive. The gunpowder drive has defects such as non-reusable, non-testable, and expensive; After vibration, there are problems of high working voltage and mutual adhesion between moving parts; the motor drive has defects such as large volume and complex structure; in order to solve the problems existing in the driving mode in the field of attitude control technology, some smart materials, such as dielectric elastomers, etc. The research is used to realize attitude control actuation.

Problems solved by technology

[0002] In the field of attitude control technology, at present, most of the drive methods for attitude control devices at home and abroad are gunpowder drive, electromagnetic drive or motor drive. The gunpowder drive has defects such as non-reusable, non-testable, and expensive; After vibration, there are problems of high working voltage and mutual adhesion between moving parts; the motor drive has defects such as large volume and complex structure; in order to solve the problems existing in the driving mode in the field of attitude control technology, some smart materials, such as dielectric elastomers, etc. Research used to implement attitude control actuation

Silvain Michel of the Swiss Federal Materials Testing and Research Laboratory used dielectric elastomers to make the left and right tail rudders and elevators of the airship, and realized the flight control of the airship. The airship can achieve a deflection of 30° and generate a moment of 2.76N cm. However, this technology has disadvantages such as the driving voltage needs to be as high as several thousand volts, and the driving force is small.
