The invention discloses a bolt structure and a vehicle, and the bolt structure comprises a screw rod and a gasket; a nut is arranged at one end of the screw; a groove which is sunken in the radial direction of the screw rod is formed in the peripheral wall of the screw rod and penetrates through the screw rod in the axial direction of the screw rod; the gasket is arranged on the screw rod in a sleeving mode and can abut against the nut; a protrusion matched with the groove is formed on the inner circumferential wall of the gasket, and the protrusion is connected into the groove in a clamped mode. A first step face and a second step face are formed on the side wall of the protrusion, and at the joint of the first step face and the second step face, the second step face sinks and changes suddenly towards the protrusion, so that when the bolt structure is impacted, the side wall of the groove is separated from the first step face and impacts the second step face, huge shear stress is generated at the impact moment, the screw rod is broken, and the bolt structure is damaged. And the nut is separated from the screw rod, so that the vehicle door and the vehicle body can be easily separated, a driver and passengers can leave the vehicle to avoid danger or rescue injured drivers and passengers from the vehicle, and the escape or rescue time is shortened.

    本发明公开了一种螺栓结构及车辆,其中,螺栓结构,包括螺杆和垫圈;螺杆的一端设有螺帽;螺杆外周壁上形成有沿螺杆径向凹陷的凹槽,凹槽沿螺杆轴向贯通螺杆;垫圈套设在螺杆上,并可与螺帽相抵接;垫圈的内周壁上形成有与凹槽相适配的凸起,凸起卡接在凹槽内;凸起的侧壁上形成有第一台阶面和第二台阶面,在第一台阶面与第二台阶面的衔接处,第二台阶面向凸起凹陷突变,以便螺栓结构受到撞击时,凹槽的侧壁与第一台阶面相脱离并撞击第二台阶面,撞击瞬间产生巨大的剪应力,将螺杆撞断裂,使得螺帽与螺杆相分离,从而使车门与车体可以轻易分离,以便于驾乘人员离开车辆进行避险或者是将车上受伤的驾乘人员从车上救出,缩短逃生或救援时间。
