Abstract: A human-eye state detection device is provided, which includes an image capturing device and a processor. The image capturing device is configured to continuously capture a plurality of frames of facial images of a user. The processor determines an eye area from the frames of facial images, and calculates an eye-opening average based on the eye area. The processor repeatedly updates the eye-opening threshold based on the average eye-opening value. In response to the average eye-opening value being less than the eye-opening threshold, the processor determines that the user is in an eye-closing state.

Abstract: The casing assembly includes a casing, a cage, a supporting component, an engagement component and an operation assembly. The cage is movably disposed in the casing. One end of the supporting component is pivotably disposed on the casing, and another end of the supporting component is slidably disposed on the cage. The engagement component is pivotably disposed on the cage and selectively engaged with the supporting component to position the cage. The operation assembly is movably disposed on the cage and connected to the engagement component. The operation assembly is movable relative to the cage, and the engagement component is driven to disengage from the supporting component via the operation assembly selectively.

Abstract: A pushing mechanism, configured to be disposed on a case body, includes a fixed component, a slidable component and a pushing component. The slidable component is disposed on the fixed component and includes a connection plate and a guiding plate. The guiding plate protrudes from the connection plate and has a first supporting portion, a second supporting portion and an inclined guiding portion connected to the first supporting portion and the second supporting portion. The first supporting portion is closer to the connection plate than the second supporting portion. The pushing component is disposed on the fixed component. A slidable direction of the pushing component differs from a slidable direction of the slidable component. When the slidable component is moved relative to the fixed component, the pushing component is guided by the guiding plate to slide between the first supporting portion and the second supporting portion.
