Abstract: A docking station having adaptor function contains: an AC-DC conversion module, a charging module, a control module, and at least two interface modules. When an AC power source outputs AC power into the AC-DC conversion module, the AC-DC conversion module outputs two DC powers to the charging module and the control module according to the AC power. The control module is enabled to operate according to the first DC power. And, according to the second DC power, the control module controls the power charging module to charge each target end-user devices being connected to a corresponding interface module. When interface modules respectively connect to target end-user devices, the control module controls the signal transmission sequence of interface modules to provide data transmission paths amongst the end-user devices via the interface modules. The docking station also serves as an accessory for supplying electric power to an end-user device for endurance use.

Abstract: A clamping bracket includes base casing, clamping mechanism, controlling mechanism, and anchor mechanism. Clamping mechanism includes first and second clamping members. Controlling mechanism includes a first sliding member being connected to the first clamping member and being slidingly connected to the base casing, and a transmission member being connected to the base casing. Through the transmission member's own movement, transmission member drives the first clamping member to move toward or away from the second clamping member. Anchor mechanism includes a first anchor member that connects to the transmission member and a second anchor member that connects to the base casing. The first anchor member is in an unlock state when separating from the second anchor member and in a lock state when engaging with the second anchor member. Anchor mechanism allows the variable distance between the first clamping member and the second clamping member for holding different mobile devices.
