Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a high-voltage testing device. Background Art

[0002] With the development of the automobile industry, the requirements for active safety of automobile driving are getting higher and higher. At the same time, with the advancement of world science and technology, the requirements for automobile intelligence are increasing year by year. Therefore, the highly integrated braking system IBC is born. IBC replaces a large number of independent components required for low vacuum or no vacuum systems with an integrated unit, including electronic stability control system ESC, vacuum booster and related cables, sensors, switches, electronic controllers, vacuum pumps, etc. The core of the system is an actuator driven by an ultra-high-speed brushless motor, which is monitored by a rotary encoder. The encoder provides the central electronic control unit ECU with the number of motor revolutions, speed and position data. At the same time, an independent hydraulic circuit is integrated into it, which uses electronic signals to convey the driver's braking intention to the system, maintaining the brake feel of traditional hydraulic brakes. The brushless motor provides the system with extraordinary braking and electronic stability functions. It can convert a vehicle deceleration of one g in less than 150 milliseconds with an ultra-high pressure rise rate. Compared with existing ESC systems, IBC is also smaller and lighter. Traditional components weigh 7 kilograms, while IBC weighs only 4 kilograms.

[0003] Considering that T-IBC is an important safety component in the car, the product needs to be tested for performance and sealing during research and development to ensure product reliability. Currently, there is no ready-made performance testing equipment on the market, which makes it impossible to judge the performance of the product. Therefore, a fully automatic high-voltage testing machine is proposed. Utility Model Content

At the same time, it reduces the time wasted due to test failure caused by abnormal data. It has a simple structure, strong practicality, can improve work efficiency, and reduce labor intensity.

[0014] 2. The utility model also connects the hose on the high-pressure test oil circuit with the product outlet, wherein the pressure sensor, high-pressure filter element, high-pressure control valve, and calibration cylinder are integrated together to simulate automobile braking.
