The cab turnover structure comprises a turnover part, a driving assembly and a transmission mechanism, the turnover part is provided with a fixed end and a movable end which are oppositely arranged, the fixed end is installed on a cab longitudinal beam, the movable end is rotatably installed on a front suspension lower support along the left-right axis, the driving assembly is installed on the front suspension lower support, and the transmission mechanism is installed on the front suspension lower support. The driving assembly comprises a driving part capable of rotating and moving, the transmission mechanism comprises a worm gear and a worm which are meshed with each other, the worm extends in the front-back direction and is in driving connection with the driving part, the worm gear rotates along the axis in the left-right direction and is in transmission connection with the overturning part, and when the driving part rotates, the driving part drives the worm to rotate, and the worm rotates to drive the worm gear to rotate. Due to the fact that the worm gear and the worm have the self-locking function, the turnover part can be stably fixed to the position where the turnover part needs to be located, in addition, the worm gear and the worm are matched, troubleshooting is convenient, the turnover safety of the cab is greatly improved, and assembly is easy to operate.
