Abstract

The invention discloses an ECU sealing performance detection device with reliable sealing and pressing. The ECU sealing performance detection device comprises a clamp body, linear guide rails, slidingblocks and a supporting plate, wherein the clamp body is used for positioning an ECU, the linear guide rails are arranged on the clamp body, the sliding blocks are in horizontal sliding fit with thelinear guide rails, the supporting plate is arranged on the sliding blocks, a first inclined plane is arranged on the clamp body, a linear driver is arranged on the supporting plate, the linear driveris connected with an inclined block, the inclined block is provided with a second inclined surface matched with the first inclined surface, the inclined block is connected with an elastic sealing plate, the inclined block is provided with a vent hole, and a sealing hole communicating with the vent hole and the ECU air inlet is formed in the elastic sealing plate. According to the ECU sealing performance detection device, the technical problem that the air inlet of the ECU is difficult to seal is solved, and rapid assembling and disassembling of products can be achieved.

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 [0004] The techni...
