AI Technical Summary
In existing technologies, the way electronic device accessories are fixed to main devices affects the user experience and the reliability of electrical connections is insufficient.
The system employs permanent magnets and electromagnets as adsorption components in both accessory and main components. Direct fixation and electrical connection are achieved through adsorption force, and the adsorption force is adjusted by utilizing the energization state of the electromagnet to enhance its firmness.
It simplifies the fixing process, reduces the impact of additional structures, and improves electrical connection reliability and user experience.
