Abstract:
A PDA battery buckling device having a battery housing, in that an embedding room is installed in a PDA main frame, the embedding room is formed with an actuation switch and a circuit board with a plurality of power receiving joints therewithin, a lower side of the embedding room having a transversal plate installed with a positioning groove; the battery housing comprising;a wedge plate being a sliding plate having a middle portion and two sides, the middle portion having a top surface having a tilt groove and two sides having respective sliding strips, a lower middle portion of the wedge plate being installed with a movable plate; a driving plate being a movable plate having an outer lateral edge extending with a bent lateral plate; an inner battery casing extending with a half case with hook case, a top of the hook case being installed with a plurality of power supplying joints, a lower portion of the inner battery casing being installed with a sliding track for positioning the driving plate, and a lateral wall at opposite sides being installed with a notch for being slid by the lateral plate of the driving plate, a bottom of the inner battery casing being suspended with a sliding groove for placing the wedge plate; an outer battery casing being a half case for being combined with the inner battery casing, the outer battery casing having a bottom plate formed with a through hole; an elastomer having an end resisting against the driving plate, and having another end resisting against a parallel spacer of the inner battery casing; and a battery for supply power to the power receiving joints; wherein after the battery housing is placed in the embedding room at a rear side of the PDA main frame, the power supplying joints arc in contact with the power receiving joints; then, by the wedge plate to control the location of the driving plate so that the wedge plate and the battery housing is capable of clamping or releasing the transversal plate, at the same time, the wedge plate cause the lateral plate of the driving plate to move upwards or downwards for turning on or off the actuation switch.
