The invention discloses a forecabin structure with improved NVH (Noise Vibration and Harshness) performance and a vehicle, and the forecabin structure comprises a forecabin assembly; the front auxiliary frame is at least provided with eight mounting points; the front auxiliary frame is mounted at the bottom of the front cabin assembly; the front subframe and the forecabin assembly form a first structural ring, a second structural ring, a third structural ring and a fourth structural ring. Vibration of tires, vibration and noise of a driving motor and vibration and noise of a radiator and a water pump can be prevented from being transmitted to a passenger compartment through automobile body parts. And the NVH quality can be improved. Especially when an automobile passes through a pit, the up-down jumping positions of two tires are different, and the sufficient rigidity can prevent an automobile body from being excessively twisted and deformed.

    本发明公开了一种改善NVH性能的前舱结构和车辆,其中,该前舱结构包括,前舱总成;前副车架,至少具有8个安装点;所述前副车架安装于所述前舱总成的底部;所述前副车架与所述前舱总成形成有第一结构环、第二结构环、第三结构环和第四结构环。本发明能够防止轮胎的振动、驱动电机的振动和噪声、散热器和水泵的振动和噪音会通过车身零件传递到乘员舱。有利于提高NVH品质。尤其是汽车在过坑时两个轮胎上下跳位置不一样,足够的刚度能够防止车身扭转变形过大。
