AI Technical Summary

Technical Problem

The integration of controllers and actuators in existing closed-loop air supply units results in high maintenance costs, fails to meet the needs of automobile manufacturers, and has a significant impact from failures, leading to poor system reliability.

Method used

The controller and actuator are separated, and the external controller and actuator are connected through a transceiver to enable independent upgrades and maintenance. The transceiver is only used for signal transmission. The solenoid valve and motor are controlled in real time by the external controller, and the sensor signals are transmitted centrally through the wiring harness.

Benefits of technology

It reduces maintenance costs and downtime, improves system reliability and production efficiency, meets the needs of automobile manufacturers, and enables independent development and maintenance of controllers and actuators.

Abstract

The utility model discloses a separated closed type air supply unit actuator which comprises an external controller, an execution unit, a sensing unit and a transceiver, the execution unit comprises a plurality of execution elements and a pneumatic block used for integrating and installing the execution elements, and the execution elements comprise a compressor, a motor, a functional valve element and a dryer. The sensing unit comprises a plurality of functional sensing elements, each functional sensing element at least comprises a temperature and pressure sensor and is mainly installed on the pneumatic block, and the transceiver is arranged on the pneumatic block and comprises a circuit board used for transmitting current, voltage or sensing signals. The compressor and the functional valve element receive output of current and voltage from an external controller through the circuit board, and the functional sensing element transmits signals to the external controller through the circuit board. After the controller and the actuator are separated, the controller can be upgraded and maintained independently, and the whole actuator does not need to be replaced.
