New Energy Vehicle AI

Industry Core: New energy vehicle AI is the integration of AI technology and the new energy vehicle industry, covering intelligent driving domain controllers, cockpit AI, autonomous driving sensors, AI battery management, etc. It is the core support for the intelligence of new energy vehicles, and is widely used in passenger cars, commercial vehicles, new energy special vehicles and other fields. The industry has extremely high requirements for the automotive-grade reliability, vibration resistance, high and low temperature durability, EMI shielding, and lightweight of hardware components, and the customization needs of different vehicle models and intelligent driving schemes are prominent, which must strictly comply with automotive-grade certification standards.

AI Scenarios: Intelligent driving domain controllers (AI autonomous driving control, path planning, obstacle recognition), cockpit AI (voice interaction, intelligent navigation, scenario-based control), autonomous driving sensors (AI perception of lidar, cameras, millimeter-wave radar), AI battery management (battery status monitoring, charging optimization, safety early warning). These scenarios all require hardware components to adapt to the complex working conditions of vehicle driving and ensure the stable and precise operation of the AI system.

Key Hardware Products: On-board connector housings (MIM process non-standard housings, signal connector housings), lidar brackets (customized brackets, lightweight brackets), anti-vibration fasteners (automotive-grade locknuts, non-standard bolts), thermal management hardware (customized heat dissipation pipes, heat dissipation brackets), intelligent hinges/slide rails (cockpit hinges, door slide rails). In addition, it also includes intelligent driving domain controller fixing parts, sensor mounting hardware, battery management system hardware accessories and other non-standard customized parts.

Core Functions: Achieve reliable connection of on-board AI equipment to prevent loosening caused by high-frequency vibration during vehicle driving; provide EMI electromagnetic shielding to avoid electromagnetic interference generated by on-board electronic equipment and sensors, ensuring the precise operation of intelligent driving and cockpit AI systems; achieve efficient heat dissipation of on-board equipment to avoid equipment failure caused by high and low temperature environments; adapt to complex working conditions of vehicle driving (high and low temperature, vibration, humidity) and have automotive-grade durability; achieve lightweight design, reduce vehicle energy consumption, and improve endurance; adapt to the flexible movement of cockpit, door and other components to improve user experience.

Selection Notes & Processing Advantages (Machining/Cold Heading):

1. Automotive-Grade Anti-Vibration Connection for Complex Driving Conditions: During vehicle driving, high-frequency vibration and bumps will occur. The connecting hardware of on-board AI equipment (intelligent driving domain controller, sensor) is prone to loosening and falling off, which seriously affects the operation safety of the AI system. The automotive-grade high-strength locknuts we produce using cold heading technology are made of high-strength alloy steel, with high thread accuracy, combined with nylon locking, wedge anti-loosening or chemical anti-loosening design. Verified by automotive-grade vibration test (ISO 16750), they can withstand high and low temperature cycles of -40℃~125℃ and high-frequency vibration without loosening or failure, ensuring the safe connection of intelligent driving domain controllers, sensors and other equipment. For large-size connection needs, non-standard large-size bolts can be produced through the combination of cold heading and machining processes, taking into account automotive-grade strength and installation adaptability.

2. Complex Structure and Lightweight for Vehicle Endurance Needs: Structural parts such as lidar brackets and on-board connector housings need to have complex structures and lightweight characteristics, which are difficult to achieve with conventional processing technologies. We use CNC machining of aluminum alloy (such as 6061/7075) to process special-shaped structural parts such as lidar brackets. On the premise of ensuring high strength (tensile strength ≥300MPa), we achieve lightweight design, reducing the weight by more than 40% compared with ordinary steel parts, reducing vehicle energy consumption and improving the endurance of new energy vehicles. For complex structures such as on-board connector housings, a combination of cold heading and MIM processes is adopted. First, the main structure is formed by cold heading, and then the interface and heat dissipation holes are accurately trimmed by machining to ensure structural accuracy and sealing, and at the same time achieve a perfect combination of lightweight and complex structure.

3. Precision Thread and EMI Shielding for Intelligent Driving Needs: On-board high-voltage connectors, sensor connectors, etc., require special thread specifications (such as American standard threads, non-standard pipe threads), and need to have good EMI shielding performance to avoid electromagnetic interference affecting the intelligent driving system. We have the ability to develop non-standard cold heading molds. According to customer needs, we can customize the production of fasteners with special thread specifications, ensuring the one-time forming accuracy and sealing of threads, preventing the penetration of water vapor and dust. At the same time, the size and structure of the shielding cover are accurately controlled through machining to improve the EMI shielding effect, with a grounding resistance of ≤0.1Ω, adapting to the EMI needs of intelligent driving sensors and complying with the automotive-grade certification standard (AEC-Q200).

4. Automotive-Grade Durability and Rapid Adaptation to Vehicle Model Iteration: New energy vehicle models have a fast iteration speed. Different vehicle models have great differences in intelligent driving schemes and cockpit designs, with frequent customization needs for hardware parts, and must meet automotive-grade durability requirements such as high and low temperature, salt spray, and vibration. Our hardware parts have passed automotive-grade tests, with high and low temperature cycles (-40℃~125℃) ≥1000 times without failure, and salt spray test ≥500 hours, meeting automotive-grade durability requirements. At the same time, we have the ability of rapid mold opening and programming. According to the design needs of different vehicle models, we can quickly complete the trial production and mass production of non-standard hardware parts, shorten the vehicle model iteration cycle, reduce the customer's R&D costs, and provide automotive-grade certification reports to help customers' products launch quickly.
