[0034] The fastening screw 40 passes through the chassis housing 20 and the end of the chassis frame 10 to abut against the micro switch 30 and close it. After the fastening screw 40 is removed, the micro switch 30 is disconnected.

[0035] Here, the micro switch 30 is a circuit switch control connected in series to the power supply line of the self-moving chassis. By closing the micro switch 30, the chassis power supply line can be turned on, thereby enabling the self-moving chassis to work normally.

At this time, the fastening screws 40 need to be unscrewed to separate the chassis shell 20 from the chassis frame 10. When the fastening screws 40 are screwed out, the end away from the nail cap will be separated from the microswitch 30. At this time, the microswitch 30 is in an off state, disconnecting the chassis power supply circuit. In this way, it is avoided that the self-moving chassis is not in a shut-down state and the chassis shell 20 is disassembled for maintenance to cause damage to the internal battery and electronic components, thereby improving the safety of the use of the self-moving chassis.

[0036] It should be pointed out here that the chassis housing 20 is generally detachably connected to the chassis frame 10 by a plurality of fastening screws 40 distributed on the outer contour of the chassis periphery 20 , but only one fastening screw 40 is required to abut against the micro switch 30 .
