The invention discloses an automobile fuel tank protection structure. The structure comprises a protection box, a plurality of protection mechanisms and a plurality of damping mechanisms. A pluralityof air bags are uniformly arranged on an outer ring of the protection box; a plurality of through holes are uniformly arranged in the outer ring of the protection box; an oil tank is arranged in an inner cavity of the protection box; a plurality of protective grooves are uniformly formed between the inner wall and the outer wall of the outer ring of the protective box; the protection mechanism comprises an air cylinder, two pistons are arranged in the inner cavity of the air cylinder; a toothed rod is connected to the top and the bottom of the air cylinder in a penetrating mode; the toothed rod is fixedly connected with the piston through a screw; a protective spring sleeves the outer ring of the toothed rod in the inner cavity of the air cylinder; one side, away from the oil tank, of thetoothed rod located outside the air cylinder is engaged with a gear; and supporting plates are arranged on a front surface and a back surface of the gear, and a first rotating shaft is connected between the two supporting plates. By means of cooperative work of the protection mechanisms, the through holes, the air bags and the protective grooves, when the oil tank is impacted, an impact force borne by the oil tank can be greatly reduced, an anti-collision capacity of the oil tank is greatly improved, and the oil tank is prevented from being damaged due to impact.

    本发明公开了一种汽车油箱保护结构,包括保护箱、多个防护机构和多个减震机构,保护箱的外圈均匀的设置有多个气囊,保护箱的外圈均匀的开设有多个通孔,保护箱的内腔设置有油箱,保护箱外圈的内外壁之间均匀的开设有多个防护槽,防护机构包括气缸,气缸的内腔设置有两个活塞,气缸的顶部和底部均贯穿连接有齿杆,齿杆通过螺钉与活塞固定连接,齿杆位于气缸内腔部分的外圈套设有防护弹簧,齿杆位于气缸外部分远离油箱的一侧啮合有齿轮,齿轮的正面和背面均设置有支板,两个支板之间连接有第一转轴,通过防护机构、通孔和气囊和防护槽配合工作,在受到撞击时,可大大减小油箱所受的撞击力,大大提高油箱的防撞能力,避免其因撞击而破损。
