Pressure compensation device and ECU module including the same

Abstract

Disclosed herein is a pressure compensation device for securing the air permeability of the electronic control unit (ECU) of a vehicle. A pressure compensation device according to an aspect of the present invention includes a vent unit integrated with a connector on a part of an ECU on which an electronic control element is mounted, wherein a vent hole penetrating the inside and outside of the case of the ECU in which the electronic control element is received is formed in the vent unit and a cover unit integrated with a vehicle-side connector in such a way as to form electrical connection with the ECU and configured to form a protection wall by covering part of the upper side of the vent unit when the ECU-side connector and the vehicle-side connector are coupled.

Description

technical field [0001] The present invention relates to a pressure correction device, more specifically, a pressure correction device and an electronic device including the device for ensuring the air permeability of an electronic control unit (ECU) equipped with an electronic control unit (ECU) that electrically controls various parts of an automobile. Control unit module. Background technique [0002] Generally speaking, a vehicle is equipped with an electronic control device capable of electronically controlling various devices. This type of electronic control device receives information from sensors or switches installed in various parts of the vehicle, processes the received information to optimize vehicle performance, improve ride comfort and stability, or provide various conveniences for the driver and passengers. A variety of electronic controls. [0003] For example, electronic control devices such as ECU (Electronic Control Unit) that electronically control the o...

Problems solved by technology

[0007] Among them, the plug type disclosed in Japanese Laid-Open Patent No. 2008-078506 belongs to an effective structure capable of satisfying both air permeability and sealing (seal) property, but due to the application of another pressure correction device such as a plug-type filter, an additional assembly process is required and causes Costs have risen, so product mass production and cost cannot ensure its competitiveness

[0008] On the contrary, compared with the technology disclosed in Japanese Laid-Open Patent No. 2008-078506, the thin sheet disclosed in Japanese Laid-Open Patent No. 2008-055981 has a very simple structure and has the advantages of simplifying the assembly process and saving costs, but it cannot meet the requirements of international standards. Waterproof standard classification IP (InternationalProtection, international protection) 9K, waterproofness to high-pressure sprinkler
