In the field of new energy vehicles, the quiet effect of the electronic control system is an important indicator to measure the performance of the vehicle. In order to achieve better quiet effect, many automakers have adopted the New Energy Electronic Control Cover made of three-layer composite material plus damping material. This design not only improves the stability of the electronic control system, but also significantly reduces noise, providing passengers with a quieter driving environment.
The design principle of the three-layer composite electronic control cover is to combine multiple materials together to form complementary advantages. This composite material is usually composed of two layers of metal steel plates and a layer of polymer shock-absorbing material damping glue. The inner and outer layers use metal steel plates to provide sufficient strength and rigidity to ensure the structural stability of the electronic control cover. The middle layer uses polymer shock-absorbing material damping glue, which has excellent shock absorption and sound insulation properties.
Damping glue plays a vital role in the middle layer. When the electronic control system is running, it will generate certain vibrations and noise. These vibrations and noises will be transmitted to the body through the electronic control cover, thereby affecting the driving experience of passengers. The damping glue can absorb and consume these vibration energies, effectively reducing the transmission of vibration and noise. At the same time, the damping glue can also suppress the conduction of the drive motor order noise and the inverter switching frequency noise, further reducing the noise level of the electronic control system.
In addition to the role of the damping glue, the structural design of the three-layer composite electronic control cover also has a positive impact on its quiet effect. The rigid structure of the inner and outer metal steel plates can prevent the electronic control cover from deforming during vibration, thereby maintaining its structural stability. The damping glue in the middle layer can fill the gaps between the metal steel plates to reduce noise leakage. This tight structural design enables the electronic control cover to better isolate noise and improve the quiet effect.
In addition, the three-layer composite electronic control cover also has good corrosion resistance and insulation properties. The metal steel plate can resist the erosion of the external environment and extend the service life of the electronic control cover. The damping glue has good insulation properties and can ensure the electrical safety of the electronic control system.
In summary, the New Energy Electronic Control Cover made of three-layer composite materials plus damping materials achieves a good quiet effect through its unique design and material selection. This electronic control cover not only improves the stability and durability of the electronic control system, but also provides a quieter driving environment for passengers.
