Design method of intelligent module encapsulation structure for electric actuator

Abstract

The invention discloses a design method of an intelligent module encapsulation structure for an electric actuator. The encapsulation structure comprises a PCB, an aluminum plate, an aviation plug, an MOS tube, an LED lamp and a seal housing. According to the encapsulation structure, the protection air-tightness and space layout compactness are simultaneously ensured under the premise of meeting the functional requirements; all elements are encapsulated into the seal housing, so that integrated design of an intelligent module and a mechanical structure is achieved; the sealing property and reasonable arrangement of devices are ensured; due to the integrated design, signal loss and interference of an external signal are reduced; and the intelligent module encapsulation structure is relatively high in dustproof and waterproof capabilities, relatively reliable to run and low in maintenance cost.

Description

technical field [0001] The invention relates to an engine, in particular to a design method for an intelligent module packaging structure of an electric actuator in the engine. Background technique [0002] In engine control, the function of the actuator is to convert the control signal into an actual mechanical output. With the introduction of motor technology into the field of actuators, its control circuit is becoming more and more complex with the continuous enhancement of functions, and more functions The design is gradually transformed from the realization of mechanical structure to the way of circuit realization. The control circuit board and other control devices and line plug-in devices are collectively called intelligent modules. In addition, in order to reduce signal loss and interference, the intelligent module and the controlled mechanical components have gradually changed from separation to an integrated design, that is, they are packaged in a housing, which re...

Problems solved by technology

In addition, in order to reduce signal loss and interference, the intelligent module and the controlled mechanical components have gradually changed from separation to an integrated design, that is, they are packaged in a housing, which requires the structural packaging design of the intelligent module. Now The shortcomings of the existing technology are that while the integrated design of the intelligent module is carried out, the protection and sealing performance is low, and the space is not properly arranged, and the operation reliability is low.
