  • Publication number: 20180074548
    Abstract: A docking station for a mobile electronic device is provided. It utilizes a transmission unit and a release unit to control the positioning of a connection unit. The transmission unit includes a horizontal displacement member abutted against a floating cover for horizontal displacement upon a downward movement of the floating cover, and a pivot member mounted at the connection unit and connected to the horizontal displacement member, so that the connection unit can connect the mobile electronic device upon a downward movement of the floating cover. The release unit includes a swing arm connected with the pivot member and a button abutted against the swing arm. When the button is pressed, the swing arm is pushed to drive the connection unit to disengage from the mobile electronic device via the pivot member. Thus, the mobile electronic device can be removed.

  • Patent number: 9541956
    Abstract: A supporting structure and a docking station using the same are provided. The supporting structure includes an elastic member, a sliding member, a lifting element and a damper. The sliding member having an inclined plane is connected to the elastic member. When the elastic member receives a force, the elastic member forces the sliding member to move along an axis line with the inclined plane facing to the lifting element. The lifting element is arranged over a travel path of the inclined plane and has an abutting portion. When the lifting element receives another force so that the abutting portion abuts against the inclined plane, the sliding member stops moving and the height position of the lifting element is fixed. The damper is mated with the sliding member to slow down the velocity of the sliding member.
