Solution Overview
Problem
Automatic cleaning robots often disengage from charging docks due to incorrect positioning, leading to incomplete charging and disrupted cleaning operations, which deteriorates user experience.
Innovation Solution
A charging control method and apparatus that monitors the robot's charging status and locks the drive wheel electromagnetically during charging, preventing disengagement and ensuring complete charging by detecting unlocking triggers such as wheel rotation or completion of charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cleaning robot is allowed to move freely during charging, then the robot can be easily repositioned or removed from the charging dock, but the robot may disengage from the charging dock due to incorrect positioning or accidental movement, leading to incomplete charging
Solution Approach 1:
The system performs preliminary action by detecting the charging status before the robot can disengage, and proactively applies braking to prevent potential disengagement. The detection module identifies when the robot is in charging mode, and the control module preemptively activates the brake mechanism to secure the drive wheel, ensuring the robot remains firmly positioned on the charging dock throughout the charging process.
2Reliability
If the drive wheel is locked during charging, then the robot remains firmly positioned on the charging dock preventing disengagement, but the robot cannot be repositioned or removed from the charging dock
Solution Approach 1:
The system implements dynamics by making the brake mechanism controllable and reversible. The control module dynamically adjusts the brake state based on charging status: applying brake force when charging is detected to prevent disengagement, and releasing the brake when charging is complete or when removal is detected. This dynamic control allows the system to transition between locked and unlocked states, balancing reliability during charging with operational flexibility when needed.
3Reliability
If the robot uses electromagnetic braking to lock the drive wheel, then the robot is securely prevented from moving during charging, but additional electromagnetic components increase the device complexity
Solution Approach 1:
The system applies universality by making the electromagnetic brake mechanism serve multiple functions: it acts as a motor during normal operation to drive the wheels, and as a brake during charging to prevent movement. This multi-functionality eliminates the need for separate braking components, reducing overall device complexity while maintaining reliable charging stability. The same electromagnetic components that provide propulsion also provide braking capability through controlled current reversal or reduction.

AI summary
Embodiments of the present disclosure provide a charging control method and apparatus, and a storage medium and a cleaning robot. The method comprises: detecting the charging state of a cleaning robot; and when it is detected that the cleaning robot is in a charged state, executing a brake locking action, so that the driving wheel of the cleaning robot enters a locked state. According to the present disclosure, when the cleaning robot enters a charged state, a brake locking action is executed, so that the driving wheel of the cleaning robot enters a locked state, so as to avoid, in a charging process, accidental coming off from a charging base caused by problems such as misalignment with the charging base, and ensure that the normal charging of the cleaning robot can be completed, thus successfully completing the subsequent cleaning operation, thereby improving user experience.
