Patent attributes
In an electronic device, a lift structure, composed by electromagnets, magnetic components, and support piece, is disposed at a rear end of an electronic part and a housing. The magnetic components can be permanent magnets and disposed at the rear end of the electronic part and the support piece. The electromagnets are controlled by driving device to a configuration so as to have repulsion and attraction to the rear end and to the support piece respectively, thereby configuring the rear end to a lifted position, or to another configuration so as to have attraction and repulsion to the rear end and to the support piece respectively, thereby configuring the rear end to a retracted position. An adjusting component is further used to adjust the position of the electromagnet to determine the height of the rear end of the electronic part when set in the lifted position.
