Robot Charging Dock Locking to Prevent Electrode Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent robot charging systems face issues with reliable docking due to unintended movement of the walking mechanism, leading to potential power failure and charging failure during the charging process.
Innovation Solution
The intelligent robot system incorporates an electrode docking locking actuator, controlled by a central processing unit, which locks the walking mechanism after successful docking, using a braking device or a motor with a brake coil to prevent separation from the charging base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the walking wheel is left in free state after motor releases control, then the robot can passively move and return to charging base, but the walking wheel may move forward or backward unintentionally causing docking electrode separation
Solution Approach 1:
The patent applies preliminary anti-action by introducing a locking mechanism that activates before charging begins to prevent the walking wheel from moving during the charging process. The locking mechanism is engaged when the docking electrode contacts the charging electrode, and is released after charging completes, thereby preventing unintended movement that would cause docking separation while maintaining passive movement capability during navigation.
2Device complexity
If the docking detection is based solely on voltage or current detection, then the control is simple, but the docking may be judged successful even when not properly docked leading to power failure
Solution Approach 1:
The patent implements feedback by using multiple detection methods including voltage/current detection combined with docking state verification. The control unit receives feedback signals from the docking electrode about the actual docking status, and only judges docking successful when both electrical connection and mechanical docking are confirmed, preventing false positive detection while maintaining relatively simple control logic.

AI summary
An intelligent robot system comprising an intelligent robot (100) and a charging base (200). The intelligent robot (100) comprises a docking electrode (102), a walking mechanism (106) and a control unit (105). The docking electrode (102), the walking mechanism (106) and the control unit (105) are disposed in the body (101) of the intelligent robot (100). The charging base (200) comprises a charging electrode (201) disposed on the body (101) of the charging base (200). The intelligent robot (100) further comprises a gripping mechanism (107). When the docking electrode (102) and the charging electrode (201) dock successfully, the control unit (105) controls the e gripping mechanism (107) to lock the walking mechanism (106) to enable the intelligent robot (100) to maintain a successful docking state in the charging base (200), preventing the charging electrode (201) of the charging base (200) from being separated from the docking electrode (102) due to the improper movement of the walking mechanism (106). Any interference during of the intelligent robot (100) is thus prevented and charging efficiency is improved.
