  • Patent number: 10292284
    Abstract: The present disclosure relates to an anti-falling mechanism for preventing an electronic component installed inside a casing from falling rapidly. The anti-falling mechanism includes at least one damping gear and at least one gear rack. The at least one damping gear is disposed on the electronic component. The at least one gear rack is disposed at a position corresponding to the at least one damping gear. The at least one damping gear rotatably engages with the at least one gear rack when installing the electronic component inside the casing along a first direction at least. Therefore, even if the electronic component falls unintentionally during installation or disassembly, rotary engagement of the at least one damping gear and the at least one gear rack can reduce kinetic energy of the falling electronic component, which effectively prevents the electronic component from colliding with other components inside the casing.

  • Patent number: 9349417
    Abstract: An electronic apparatus includes an apparatus casing, using a cover mechanism, and a device unit, disposed inside the apparatus casing. The apparatus casing includes a casing body, a pivotal device, a pivot locking mechanism, and a door. The casing body structurally constrains the door to move in a direction at a side of the casing body. After sliding, the door is engaged with the pivotal device and drives the pivot locking mechanism to unlock the pivotal device so that the door can rotate to another side of the casing body by the pivotal device relative to the casing body. A manipulation area of the casing body is therefore exposed. Thereby, a user can manipulate the device unit through the manipulation area; the inner surface of the door keeps facing toward the casing body so that the apparatus casing can keep its aesthetic appearance.
