Abstract:
An engaging and ejecting device for expansion module/cell of portable computer, comprising:a control member pivotally disposed on a lateral edge of a housing of the portable computer, the control member being disposed with a first and a second control bodies which are coaxially inter-drivingly arranged, the first control body being disposed with a first force application face, the second control body being disposed with a second force application face, the force application direction of the first force application face being directed to outer side of the computer housing, while the force application direction of the second force application face being directed to inner side of the computer housing; a first resilient member one end of which is fixed at the control member, while the other end of which is in contact with the computer housing; a switch member pivotally disposed on a lateral edge of the computer housing and disposed with a sliding body, one side of the sliding body being disposed with a pivot section, a pushing block and an engaging block, the switch member being back and forth movable relative to the lateral edge of the computer housing; and an expansion module for inserting into the computer housing, the expansion module being disposed with a control block on one side corresponding to the control member, whereby when the expansion module is inserted into the computer housing, the control block contacts with the first force application face of the first control body, when the module is totally inserted into the receiving chamber of the portable computer, the control member being restored to its home position by resilient member, at this time, the control block being positioned between the first force application face of the control member and the engaging section of the switch member and the module is in an engaged state, when it is desired to eject the module out of the portable computer, the sliding body being pushed outward, at this time, the pushing section of the switch member pushing the second force application face of the second control body, making the second control body move downward relative to the portable computer, the first control body being driven by the second control body and the first control end edge being disengaged from the control block, permitting the module to be ejected out of the portable computer.
