The invention discloses a new energy vehicle motor room noise reduction system which comprises a motor room and a noise reduction cavity, the motor room is arranged in the noise reduction cavity, the noise reduction cavity comprises a top noise reduction plate, a bottom noise reduction plate, two lateral noise reduction plates and a front wall noise reduction plate, the top noise reduction plate is arranged outside the top face of the motor room in a full covering mode, the bottom noise reduction plate is arranged outside the bottom face of the motor cabin in a full-covering mode, the two lateral noise reduction plates are arranged outside the two side faces of the motor cabin in a full-covering mode, and the front wall noise reduction plate is arranged outside the front face of the motor cabin in a full-covering mode. According to the noise reduction system for the motor cabin of the new energy vehicle, the total noise reduction area is larger, the noise reduction amount is larger, and the noise reduction performance is high; and in terms of the manufacturing process, the system structure is relatively simple, the manufacturing and mounting process requirements are low, and implementation is easier.

    本发明公开了一种新能源车电机舱降噪系统,其包括电机舱和降噪腔体,电机舱设置于降噪腔体内,降噪腔体包括顶部降噪板、底部降噪板、两块侧向降噪板和前围降噪板,顶部降噪板全覆盖地设置于电机舱的顶面之外,底部降噪板全覆盖地设置于电机舱的底面之外,两块侧向降噪板全覆盖地设置于电机舱的两侧面之外,前围降噪板全覆盖地设置于电机舱的正面之外。上述新能源车电机舱降噪系统不仅降噪总面积更大,降噪量也就越大,具有较高的降噪性能;而且从制造工艺上讲,系统结构相对简单,制造和安装工艺要求低,更容易实现。
