Abstract:
A base for a display device. The base comprises a chassis, a rotational element rotatably disposed on the chassis, and an elevator joined to the rotational element. When the rotational element rotates, the elevator moves between a first position and a second position. The rotational element is a cylinder and comprises at least one inclined groove on the periphery of the cylinder. The elevator comprises at least one protrusion engaging the inclined groove. When the rotational element rotates, the protrusion slides in the inclined groove, whereby the elevator moves between the first position and the second position.
Abstract:
A display including a base, a panel and a regulating device is disclosed. The regulating device disposed between the base and the panel comprises a first element and a second element. The first element comprises a first positioning region. The second element connected to the panel and disposed on the first element to be movably switched between a first position and a second position, comprises a second positioning region detachably disposed in the first positioning region of the first element. When the second element is positioned in the first position, the second positioning region of the second element is positioned in the first positioning region of the first element; when the second element is moved to the second position from the first position, the second positioning region of the second element is positioned in the first positioning region of the first element, wherein a distance is formed between the first and second positions.
Abstract:
An external electronic device, coupled to a main electronic apparatus by USB, comprises a first USB connector connecting with a first USB port on the main electronic apparatus, and at least one extended USB port directly and electrically connected with the first USB connector for connecting other USB devices with the main electronic apparatus. The external electronic device may further comprise a second USB connector for coupling to a second USB port on the main electronic apparatus, and a circuit module coupled to the second connector, wherein the circuit module is powered by the main electronic apparatus via the second USB port rather than by a power cable.
