Embodiment Construction

[0023] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0024] Such as figure 1 The structure of the present invention shown is a waterproof and breathable structure of the electronic control unit of the electronic control braking system. The electronic control braking system includes a hydraulic control unit 10 (HCU), an electronic control unit 20 (ECU), a vehicle body firewall 30. The electronic control unit 20 is provided with an ECU circuit board 20.1.

[0025] In order to overcome the defects of the prior art and realize the invention purpose of improving the waterproof and breathable performance of the electronic control unit, the technical scheme adopted by the present invention...

Abstract

The invention discloses a waterproof and breathable structure of an electronic control unit of an electronic control brake system. The electronic control brake system comprises a hydraulic control unit and the electronic control unit, an ECU (electronic control unit) circuit board is arranged in the electronic control unit, and breather holes are formed in an HCU (hydraulic control unit) valve ina hydraulic control unit and connected with an ECU inner cavity and a mounting panel channel in the ECU circuit board. By the aid of the technical scheme, a waterproof and breathable membrane is omitted, the whole system is free from the waterproof and breathable membrane which is a weak link, and waterproof rate is greatly increased. A welding structure and welding and testing equipment corresponding to the waterproof and breathable membrane are omitted, an ECU shell structure is simplified, and cost is greatly reduced. Breathable functions are more reliable, and the breather holes cannot beblocked by dirt. The breather holes of the HCU valve are communicated with a cockpit to realize breathing of the ECU, and the waterproof performance is improved.

Description

technical field [0001] The invention belongs to the technical field of electric control braking system. More specifically, the present invention relates to a waterproof and breathable structure of an electronic control unit of an electronic brake system. Background technique [0002] Such as figure 2 As shown: the hydraulic control unit 10 is connected with the brake master cylinder-vacuum booster assembly 40 through the brake oil pipe 50 . [0003] In the prior art ABS anti-lock braking system and ESP electronic stability program, the venting mode of its electronic control unit 20 (ECU) is to set vent holes on the ECU shell 20.2, and to cover with a waterproof ventilating film 20.3 to realize waterproofing, The waterproof breathable membrane 20.3 is usually installed on the ECU shell 20.2 by ultrasonic welding. [0004] Owing to will consider the intensity of waterproof gas-permeable membrane 20.3, the air hole is done very little usually, so that be easily blocked by di...
