Automotive electronic components | New energy vehicle radar housing & EPS steering system supporting projects

1. Project background

Domestic new energy passenger vehicle manufacturers equip their models with millimeter-wave radar, ultrasonic radar perception systems, and EPS (Electric Power Steering) systems. The original radar housing of the customer has insufficient injection molding precision, which is prone to structural deformation and sealing failure under vibrational conditions. Rainwater and moisture infiltration can affect the radar's sensing performance. The EPS steering system's supporting connector has reduced terminal contact stability under high-temperature conditions in the engine compartment, posing safety hazards. There is an urgent need for an automotive-grade structure + connector integration solution.

2. Core pain points of customers

• The injection molding tolerance of millimeter-wave and ultrasonic radar housings is large, and they are prone to deformation under vibration conditions, leading to sealing failure and water ingress;

• The weather resistance of the radar housing material is insufficient, and long-term exposure to sunlight and high and low temperature environments leads to aging, which affects radar signal transmission;

• The EPS steering system connector lacks high temperature resistance and shock resistance, making it prone to poor contact on bumpy roads;

• The poor consistency of parts cannot meet the rapid assembly requirements of the automated production line for complete vehicles.

3. Customized Solutions

Our company provides an integrated solution for millimeter-wave radar housing, ultrasonic radar housing, and EPS steering system connection components:

• The radar housing is made of modified engineering plastics, injection molded with precision molds, with strict control over dimensional tolerances, and its structure is reinforced to enhance seismic performance;

• The shell is designed with a sealed groove structure, paired with a dedicated sealing ring, enhancing waterproof and dustproof performance, and adapting to complex outdoor road conditions of the entire vehicle;

• The EPS steering system's supporting connector utilizes high-temperature resistant insulation materials and optimizes the structure of the terminal spring, achieving automotive-grade shock resistance and anti-loosening performance;

• All components undergo high and low temperature, damp heat, vibration, and aging reliability tests in accordance with AEC-Q automotive standard;

• Standardized structural design, compatible with automated assembly lines in car companies, enhances assembly efficiency.

4. Project Achievements

• The structural stability of the housing for millimeter-wave and ultrasonic radar meets the standards, eliminating issues such as water infiltration and deformation, ensuring stable radar perception signals;

• The EPS steering connection component has passed the full set of vehicle specification verifications, ensuring reliable connection under high-temperature and bumpy working conditions, and safeguarding the safety of the steering system;

• The yield rate of components remains stable, the assembly efficiency of complete vehicles has increased by 30%, and the after-sales failure rate has been significantly reduced;

• Successfully selected as a core supplier for customers, providing supporting components for multiple mass-produced new energy vehicle models, with long-term stable supply.
