The invention relates to the technical field of vehicles, in particular to a cab overturning protection mechanism, a cab assembly and a vehicle. The cab overturning protection mechanism comprises a seat frame and an adjusting rod set, the seat frame comprises a top seat and supporting rods, one ends of at least two supporting rods are rotationally installed on the top seat, and the other ends of the supporting rods can be detachably installed on a chassis below a cab. The adjusting rod set comprises at least two straight rods connected in sequence, one straight rod of every two adjacent straight rods is connected with the other straight rod in a position-adjustable mode, the first straight rod in the adjusting rod set is connected with the top base, and the last straight rod in the adjusting rod set can be connected with the overturned cab. The cab assembly and the vehicle comprise the cab overturning protection mechanism, so that the situation that the cab falls back to cause damage and damage to maintainers is avoided, and the cab overturning safety is improved. The seat frame and the adjusting rod set are simple in structure, hydraulic failure and electrical failure are avoided, and the reliability of the cab overturning protection mechanism is improved.

    本发明涉及车辆技术领域,尤其涉及一种驾驶室翻转保护机构、驾驶室总成及车辆。驾驶室翻转保护机构包括座架和调节杆组,座架包括顶座和支撑杆,至少两个支撑杆的一端转动安装于顶座上,支撑杆的另一端能够可拆卸安装于驾驶室下方的底盘上。调节杆组包括至少两个依次相连的直杆,且相邻两个直杆中的一个直杆位置可调地与另一个直杆相连,调节杆组中的第一个直杆与顶座相连,最后一个直杆能够与翻转后的驾驶室相连。驾驶室总成及车辆包括上述的驾驶室翻转保护机构,以避免驾驶室发生回落导致损毁和对检修人员造成伤害,提高了驾驶室翻转时的安全性。座架和调节杆组的结构简单,不会发生液压失效和电气失效,提高了驾驶室翻转保护机构的可靠性。
