Flexible display device
First Claim
1. A flexible display device, comprising:
- a housing provided with a gap in communication with an inner cavity of the housing;
a reel located in the inner cavity of the housing and rotatably coupled to the housing;
a flexible screen component having a fixed end and a stretching end arranged opposite to each other, the fixed end of the flexible screen component being secured to the reel, and the stretching end extending out of the housing through the gap; and
an alarm assembly accommodated in the housing, and comprising an alarm and a detector electrically coupled to the alarm, the detector being configured to detect a stretched length of the flexible screen component, and the alarm being configured to be triggered to raise an alarm when the flexible screen component is stretched to a preset length;
wherein the flexible screen component has a side edge coupled between the stretching end and the fixed end;
the side edge is provided with a limiting portion protruding from the side edge and adjacent to the fixed end;
the detector is located outside the reel;
the detector detects a space between the limiting portion and the detector during the stretching of the flexible screen component, to obtain the stretched length of the flexible screen component, and when the flexible screen component is stretched to the preset length, the alarm is triggered to raise the alarm.

Abstract
A flexible display device includes a housing, a reel, a flexible screen component, and an alarm assembly. The housing is provided with a gap in communication with an inner cavity of the housing. The reel is located in the inner cavity of the housing and rotatably coupled to the housing. The flexible screen component has a fixed end and a stretching end arranged opposite to each other, the fixed end is secured to the reel, and the stretching end extends out of the housing through the gap. The alarm assembly is accommodated in the housing, and the alarm assembly includes an alarm and a detector. The detector is electrically coupled to the alarm. The detector is configured to detect a stretched length of the flexible screen component, and the alarm is configured to be triggered to raise an alarm when the flexible screen component is stretched to a preset length.
