Abstract

A lifting mechanism includes a lifting member, a first magnetic member, a rotating arm, a second magnetic member and a resilient member. The lifting member is pivoted to a first casing. The first magnetic member is fixed on the lifting member. The rotating arm is pivoted to a second casing. The second magnetic member is fixed on the rotating arm for attracting the first magnetic member as being rotated with the rotating arm to where the second magnetic member is aligned with the first magnetic member, so as to retract the lifting member inside the first casing. The resilient member resiliently abuts against the second casing and the lifting member for pushing the lifting member as being rotated with the rotating arm to where the second magnetic member is not aligned with the first magnetic member, so as to expand the lifting member out of the first casing.

Dependent claims

A lifting mechanism with retractable function adapted to an electronic device, the electronic device comprising a first casing and a second casing combined with the first casing, the lifting mechanism comprising:

a lifting member with a side pivoted to the first casing;
a first magnetic member fixed on the lifting member;
a rotating arm with an end pivoted to the second casing;
a second magnetic member fixed on the rotating arm, the second magnetic member attracting the first magnetic member as being rotated with the rotating arm to where the second magnetic member is aligned with the first magnetic member, so as to retract the lifting member inside the first casing;
and
at least one resilient member resiliently abutting against the second casing and the lifting member, the at least one resilient member pushing the lifting member as being rotated with the rotating arm to where the second magnetic member is not aligned with the first magnetic member, so as to rotate the lifting member to be expanded out of the first casing, wherein a magnetic force generated by the second magnetic member and the first magnetic member when the second magnetic member is aligned with the first magnetic member is greater than a resilient force generated by the at least one resilient member when the second magnetic member is not aligned with the first magnetic member.
