Description

technical field

[0001] The invention relates to an assembly technology of an electronic parking brake. Background technique

[0002] As the electronic parking brake (EPB) loading rate in the automotive industry is getting higher and higher, the EPB-ECU supporting the electronic parking brake is also getting higher and higher. As an electronic product, the ECU must operate normally without water entering Therefore, the waterproof requirement of ECU is the most basic requirement. Waterproof treatment is carried out during the production process, and the sealing test is carried out at the end of the assembly to verify whether the waterproof production process meets the requirements.

[0003] Since the air inlet of ECU is large, and the sealing position is injection molding, the flatness and smoothness are not high, and the sealing is difficult, and the shell of EPB-ECU is a plastic part, which cannot withstand excessive pressure. Contents of the invention
