Abstract

The invention discloses a vehicular noise reduction assembly which is suitable for a power component of the vehicle. The noise reduction assembly comprises the components of a rigid member which is fixedly connected with the power component and is arranged outside the power component and furthermore packages at least partial outer wall of the power component; and a noise absorbing member which is arranged between the outer wall of the power component and the inner wall of the rigid member. The vehicular noise reduction component according to an embodiment of the invention has a better noise reduction effect and furthermore improves comfort of the vehicle in riding.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular, to a vehicle noise reduction component, a power assembly having the same, and an electric vehicle. Background technique [0002] In the related art, the noise frequency radiated by the motor and reducer in the electric vehicle is mainly 300-2000 Hz. Although this noise frequency is lower than the engine noise frequency, since the human ear is very sensitive to the noise in the frequency range of 1000Hz-2000Hz, it seriously affects the comfort of the car, so it is urgent to improve it. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the present invention proposes a noise reduction assembly for a vehicle that is advantageous for noise reduction. [0004] The invention also proposes a power assembly and an electric vehicle with the noise reduction component. [0005...
