Description

Technical Field

[0001] The utility model relates to the technical field of wire harness locking, in particular to a wire harness locking device for a hydraulic wire-controlled brake system. Background Art

[0002] As one of the technical solutions of EHB, the One-Box hydraulic brake system has obvious advantages in energy recovery, braking performance improvement and safety and intelligent expansion. Compared with the traditional hydraulic vacuum booster brake system, the One-Box hydraulic brake system has a simple structure and light weight. A single product can replace the vacuum booster, electronic vacuum pump, ESP / ABS controller, pedal depth sensor, wiring harness, etc., which is conducive to the layout of the whole vehicle. The brake valve block in the existing One-Box hydraulic brake system is locked and connected to the MCU control unit. The MCU control unit consists of a solenoid valve coil, sensor contacts, electric booster motor interface and Can bus control interface. The wiring harness at the existing Can bus control interface is tied and fixed with a cable tie.

[0003] The control motor of the One-Box system is used to establish and amplify the brake oil pressure. There is no pressure accumulator ball on the pump body to reserve high pressure, so the motor will work frequently, generating high-frequency vibration and noise when working, driving the wiring harness at the bus control interface to generate high-frequency vibration. The existing way of tightening the wiring harness at the bus control interface with cable ties has the problem that the wiring harness is easy to loosen, increasing the risk of power failure of the One-Box wire-controlled hydraulic brake system. For this reason, we propose a wiring harness locking device for a hydraulic wire-controlled brake system. Utility Model Content
