The invention relates to a fuel tank abnormal sound preventing mechanism and a vehicle. The fuel tank abnormal sound preventing mechanism comprises a fuel tank, a wave preventing mechanism, an oil filling port, a fuel tank cover and an adjusting mechanism. The wave-resistant mechanism can be movably arranged in the fuel tank in the vertical direction; the adjusting mechanism can drive the wave-resistant mechanism to move upwards to the position above the oil filling opening when the oil tank cover is opened. The adjusting mechanism can release the wave-resistant mechanism when the oil tank cover is closed so that the wave-resistant mechanism can fall back. When refueling is needed, the fuel tank cover is opened, the adjusting mechanism drives the wave-resistant mechanism to move upwards to the position above the fuel injection port, fuel injected through the fuel injection port enters the position below the wave-resistant mechanism, after refueling is completed, the fuel tank cover is closed, the wave-resistant mechanism falls back to the position floating on the fuel surface in the fuel tank, and meanwhile gas between the wave-resistant mechanism and the fuel surface is exhausted. The wave-resistant mechanism always floats on the fuel oil surface in the fuel oil tank, so that the fuel oil in the fuel oil tank is prevented from generating surges, and the abnormal sound of the fuel oil tank is eliminated.
本发明涉及一种燃油箱防异响机构及车辆,包括燃油箱、防浪机构、注油口、油箱盖和调节机构;防浪机构可在上下方向上活动地设于燃油箱内;调节机构能在油箱盖打开时,带动防浪机构上行至注油口的上方;调节机构能在油箱盖关闭时释放防浪机构,以使防浪机构回落。需要加油时,油箱盖打开,调节机构带动防浪机构上行至注油口的上方,注油口注入的燃油进入防浪机构的下方,加完油后,油箱盖关闭,防浪机构回落至浮于燃油箱内的燃油面上,同时排出防浪机构与燃油面之间的气体,防浪机构始终浮于燃油箱内的燃油面上,避免燃油箱中的燃油产生涌浪,消除燃油箱异响。
