  • Publication number: 20240103586
    Abstract: An electronic device includes a first body, a second body, a connection device, and a flexible screen. The second body includes a first part and a second part. The second part is slidable to be pulled out relative to the first part to form an extended part or retracted to form a hidden part. The connection device connects the first body and the first part and includes a first shaft connected to the first part. The flexible screen covers the first body and the first part and covers the extended part when the second part is pulled out relative to the first part. The first part includes a lock structure. In response to the second part being retracted relative to the first part, the lock structure is in a first state.
