US Patent 10301845 Electronic system with locking function by electronically controlled

An electronic system with an electronically controlled electronic locking mechanism is provided. The system includes a first electronic device having a first part, a first fastening element, a second part, and an electronic locking element. The first fastening element is pivotally connected to the first part and rotates relatively to the first part. The second part includes a fastening portion. The electronic locking element is disposed at the first part, electronically connected to the first electronic device, and connected to the first fastening element. When the fastening portion of the second part contacts and fastens to the first fastening element of the first part, the first electronic device supplies power to the electronic locking element, and thus the electronic locking element fixes the first fastening element to lock the first part and the second part together.
