Releasing mechanism for housing of portable electronic device

摘要

A portable electronic device includes a first housing, a second housing detachably latched to the first housing through a latching tab, and a releasing mechanism. The releasing mechanism includes a button, an elastic member, and a shaft. The button surrounds the shaft and is rotatably assembled to the first housing by the shaft. The elastic member is coiled around the shaft and elastically resists the button to apply an elastic force to enable the button resisting the first housing. When the button rotates about the shaft under a pressure overcoming the elastic force, the latching tab is pushed to release the latching tab and the second housing.

主权项

1. A portable electronic device, comprising:
a first housing comprising a bottom wall and an end wall connected to and edge of the bottom wall; an outer surface of the bottom wall defines an assembling recess; a second housing having a latching tab latched to the first housing; and a releasing mechanism comprising: a button; an elastic member; and a shaft; wherein the button surrounds the shaft and is rotatably assembled to the first housing by the shaft, the elastic member is coiled around the shaft and elastically resists the button to apply an elastic force to enable the button resisting the first housing, when the button rotates about the shaft under a pressure overcoming the elastic force, the latching tab is pushed to release the latching tab and the second housing; wherein a protruding bar protrudes from an inner surface of the bottom wall and is positioned between the assembling recess and the end wall; a protrusion protrudes from a substantially middle position of the latching tab, thereby forming a concave portion between the protrusion and the second housing; the protruding bar is detachably latched in the concave portion.
