Abstract

The invention discloses an integrated sensing-actuation-energy recovery device and a brake system. The integrated sensing-actuation-energy recovery device comprises a rotor and a stator, which are installed coaxially. More than two piezoelectric components are uniformly installed on the inner side of the stator. The piezoelectric components deform towards the central axis of the rotor. More than two raised contacts are uniformly arranged on the outer surface of the rotor. When the piezoelectric components elongate, the raised contacts on the outer surface of the rotor rub against and collide with the piezoelectric components. The device can achieve the functions of a sensor, an actuator and an energy recoverer in a compact space. On the basis, a variety of integrated function devices applied to different electromechanical systems can be developed. The brake-by-wire system provided by the invention can achieve sensing and energy recovery functions at the same time, and has a good application prospect in the fields of new energy vehicles and intelligent driving vehicles.

Description

technical field [0001] The invention belongs to the technical field of intelligent structures, and in particular relates to a sensor-execution-energy recovery device and a braking system integrating sensors, actuators and energy recovery devices. Background technique [0002] Traditional electromechanical systems are generally divided into five parts: mechanical body, sensing module, information processing module, actuator and input / output interface. In MEMS, it strives to highly integrate sensors, actuators and information processing modules that meet certain functions, so that it can form an intelligent micro functional unit, that is, an intelligent structure, and further constitute an intelligent microsystem. Among them, the integration technology routes of sensors and actuators are mainly divided into two types: structural integration and functional integration. Structural integration is just to place a sensor and an actuator closely together in structure, which appears...
