With the development of new energy vehicles,people pay more and more attention to intelligence and electrification of vehicles.Electric hidden outer door handles are increasingly used in new energy vehicles.However,when the electric hidden outer door handle is been opening or closing,the actuator will yield noise.And the overlarge and offensive noise of handles may lead to the complaining of the vehicle users.In this paper,the root cause of the working noise of the electric hidden outer door handle is analyzed,and the handle is optimized from four aspects:the body structure of the outer door handle,the structure-borne path,the air-borne path and the working control strategy,which have effectively reduced the body noise of the electric hidden outer door handle and its radiation noise to the passenger compartment.This study has a certain reference and guiding significance for the optimal design of electric hidden outer door handles of vehicles.
