AI Technical Summary
Existing cleaning robot gearboxes are complex and costly, and the precision meshing of micro gears requires high precision, resulting in low production yield. Overload protection mechanisms are prone to wear and jamming, affecting obstacle crossing stability and cleaning effectiveness.
It adopts a large-module gear mechanism and parallel shaft transmission structure, combined with a multi-stage transmission design, to enhance gear strength and wear resistance, and reduce manufacturing difficulty and cost; through the cooperation of the swing arm assembly and the side wheel, it achieves agile and stable obstacle crossing action.
It achieves a larger transmission ratio and torque output, reduces production costs, avoids transmission jerking and jamming, ensures the immediacy and continuity of obstacle-crossing actions, and improves the obstacle-crossing ability and stability of the cleaning robot.
