Problems solved by technology

[0002] The circuit board of the diesel engine controller is often connected with an atmospheric pressure sensor chip. In the prior art, air holes are often opened on the controller housing, and a filter device is installed on the air hole, which solves the problem of atmospheric collection to a certain extent, but it is prone to Electromagnetic leakage, water blockage problems, resulting in the reduction of electromagnetic compatibility of the control system, and the imbalance of air pressure inside and outside the controller

Abstract

The invention provides a controller atmospheric pressure balancing device which comprises a gas nozzle, a high-strength silicon rubber hose, an air joint, a vent plug, a controller cover, a controllerbody, a conductive seal ring and a circuit board. The small-diameter gas nozzle is introduced into a built-in filter device through a pipeline, the same atmospheric pressure inside and outside a controller is realized, the collection of outside atmosphere by an atmospheric pressure sensor on the circuit board in a box is facilitated, the air pressure of a position where an atmospheric pressure sensor chip on the circuit board in the controller is located is the same with outside atmospheric pressure, the outside interface of the controller atmospheric pressure balancing device is small, the possibility of stagnant water is little, electromagnetic shielding performance is not lost, and the controller atmospheric pressure collection performance and electromagnetic compatibility are ensured.

Description

technical field [0001] The invention belongs to the technical field of diesel engine control, in particular to a controller atmospheric pressure balance device. Background technique [0002] The circuit board of the diesel engine controller is often connected with an atmospheric pressure sensor chip. In the prior art, air holes are often opened on the controller housing, and a filter device is installed on the air hole, which solves the problem of atmospheric collection to a certain extent, but it is prone to Electromagnetic leakage, water blockage problems, resulting in the reduction of electromagnetic compatibility of the control system, and the imbalance of air pressure inside and outside the controller. Contents of the invention [0003] In view of this, the present invention aims to propose a controller atmospheric pressure balance device to solve the contradiction between the real-time acquisition of atmospheric pressure in the controller and the electromagnetic comp...
