The invention discloses a hydrogen energy vehicle hydrogen leakage protection device, which comprises a vehicle body and a installation cover arranged on a chassis of the vehicle body, a hydrogen storage bottle is fixedly arranged in the installation cover, and sealing mechanisms are symmetrically arranged on the side wall of the opening end of the installation cover and used for blocking hydrogen leaked from the hydrogen storage bottle. A hydrogen sensor is arranged on the side wall of the upper side of the installation cover, the sealing mechanism comprises a sealing shell, a sealing strip, a magnetic plate, electromagnets, reset springs and guide rods, two groups of electromagnets are symmetrically arranged on the side wall of the upper end of the vehicle body chassis, the number of each group of electromagnets is two, and the guide rods slidably penetrate through the electromagnets. The invention relates to the technical field of new energy vehicles, and the leakage protection device can effectively prevent hydrogen leaked from a gas storage bottle from being accumulated at the bottom of the vehicle and can directionally discharge the hydrogen; Meanwhile, automatic fire extinguishing and cooling treatment can be effectively carried out under the condition that open fire occurs at the bottom of the vehicle, and explosion is prevented.

    本发明公开了一种氢能汽车氢气泄露防护装置,包括车体以及设置于车体底盘上安装罩,且安装罩中固定设置有储氢瓶,所述安装罩的开口端侧壁对称设置有密封机构,用于对储氢瓶泄露的氢气进行封堵,所述安装罩的上侧侧壁设置有氢气传感器,所述密封机构包括密封壳、密封条、磁板、电磁铁、复位弹簧以及导杆,所述车体底盘的上端侧壁对称设置有两组电磁铁,且每组的数量为两个,所述电磁铁上滑动贯穿有导杆。本发明涉及新能源汽车技术领域,该泄露防护装置可以有效防止储气瓶泄露的氢气在车底积聚,且可以定向对其进行排放;同时,可以有效对车底出现明火的情况进行自动灭火降温处理,防止发生爆炸。
