Portable electronic device with chip card ejecting mechanism

摘要

A chip card ejecting mechanism includes a base body, a push member, a rotating member and an elastic member resisting between the base body and the rotating member. The base body includes a guiding member defining a hole and having a number of guiding rails. Each guiding rail includes a resisting surface and a guiding surface. The push member includes a push rod extending through the hole and a number of active gears. Each active gear defines an active cooperative surface. The rotating member includes a number of the passive gears. Each passive gear includes a passive cooperative surface. When the push member is pressed toward the rotating member by a transient external force, the rotating member compresses the elastic member until the active cooperative surface arrives at the guiding surface, the elastic member releases and drives the passive cooperative gears to slide along the first sliding slot.

主权项

1. A chip card ejecting mechanism comprising:
a base body, the base body comprising a guiding member defining a hole, the guiding member comprising a plurality of guiding rails, adjacent guiding rails forming a first sliding slot, each guiding rail further comprising a resisting surface and a guiding surface having a same inclined direction; a push member, the push member comprising a push rod extending through the hole and a plurality of active gears slidably received in the guiding member, each active gear defining an active cooperative surface; a rotating member comprising a plurality of the passive gears, each passive gears comprising a passive cooperative surface resisting against one of the active cooperative surface; an elastic member, the elastic member resisting between the base body and the rotating member; wherein when the push member is pressed toward the rotating member by an external force, the rotating member compresses the elastic member until the active cooperative surfaces arrive at the guiding surface, the passive gears slide into the first sliding slots along the active cooperative surfaces and the guiding surfaces, after the external force is removed, the elastic member releases and drives the passive gears to slide along the first sliding slot so that the rotating member push the push rod to expose from the hole.
