According to the automatic floor wiping machine provided by the invention, the collision plate 20 is arranged on the main body 10 and can move back and forth, so that a buffer effect is achieved, the main body 10 is further protected from direct collision, and in addition, the collision plate 20 and the collision sensor are matched, so that a scrubbing route can be optimized, and the scrubbing effect is improved. Locking structure 30 is capable of mounting cleaning pad 60 to ensure that cleaning pad 60 is securely mounted for proper scrubbing operation of the robotic scrubber, and locking structure 30 is capable of releasing cleaning pad 60 by engaging unlocking member 40 with linkage 50 to facilitate cleaning or replacement of cleaning pad 60, and is flexible and convenient to use. The unlocking member 40 is provided on the collision plate 20, and is operated conveniently, when the collision plate 20 is moved to a position close to the main body 10, the linkage mechanism is triggered by the unlocking member 40, and thus the locking structure 30 releases the cleaning pad 60; of course, when the collision plate 20 is not close to the main body 10, the linkage mechanism 50 cannot be triggered, and the locking structure 30 cannot release the cleaning pad 60, so that the cleaning pad 60 is prevented from being released by mistake in the cleaning process, and a user does not need to remount the cleaning pad again to continue the scrubbing work, thereby reducing unnecessary troubles, ensuring smoother use and good user experience.

In the embodiment shown in fig. 1, the collision plate 20 is provided with guide holes 21 penetrating through front and rear surfaces thereof, and the unlocking member 40 is movable along the guide holes 21 between a third position distant from the link mechanism 50 and a fourth position close to the link mechanism 50, the solid arrows in fig. 1 being the moving direction of the unlocking member 40.
