Patent number: 9541956Abstract: 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.Type: GrantFiled: November 12, 2014Date of Patent: January 10, 2017Assignees: UNIVERSAL SCIENTIFIC INDUSTRIAL (SHANGHAI) CO., LTD., UNIVERSAL GLOBAL SCIENTIFIC INDUSTRIAL CO., LTD.Inventors: Ming-Jen Chen, Kuo-Kuang Liu, Yu-Chen Chu, Chang-Cheng Lin
