The entire operation is described below by taking the first battery 20 as an example, but the present invention is not limited to this, and the same operation can also be performed on the second battery 30 .

Please refer to FIGS. 8A , 8B and 8C. In a normal use state, the first engaging portion 412 of the first fastener 41 and the second engaging portion 422 of the second fastener 42 are in an engaging state, and the third The engaging portion 423 is in an engaging state with the latching member 50 corresponding to the first battery 20 , so the first battery 20 cannot be separated from the main body 10 at this time. In one embodiment, the hook portion 425 of the second engaging portion 422 abuts against the second side 412b of the first engaging portion 412 to form the engaging state of the first engaging portion 412 and the second engaging portion 422 The third engaging portion 423 uses the convex portion 426 against the corresponding card seat 51 to form the engaging state between the third engaging portion 423 and the latching member 50 .

Please refer to FIGS. 9A and 9B in conjunction with FIG. 3 , when the first braking unit 411 of the first fastener 41 is pushed to move along the _first axis A1 and the first engaging portion 412 is disengaged from the second engaging portion 422, The first braking unit 411 also drives the magnetic element 413 to move, so that the distance between the magnetic element 413 and the Hall sensor 11 changes, then the Hall sensor 11 generates a first signal and transmits it to the control unit 12 , then the control unit 12 Knowing that the first battery 20 is about to be removed, the control unit 12 turns off the power supply of the first battery, and changes the electronic components in the main body 10 that were originally powered by the first battery 20 to be powered by the second battery 30, or converts at least one application program off, so that the power supply of the second battery 30 is sufficient to supply the portable electronic device for continuous operation.

10A, 10B, 10C and 10D, since the second engaging portion 422 has been separated from the first engaging portion 412, the second braking unit 421 is no longer limited by the first braking unit 411, and the user can push The second braking unit 421 of the second fastener 42 moves along the _second axis A2, and the third engaging portion 423 is disengaged from the engaging state with the engaging member 50 during the movement, so that the first battery 20 can be connected to the main body 10 at any time. separation. In one embodiment, the protruding portion 426 is driven by the third engaging portion 423 to disengage from the card holder 51 to release the engaging state of the third engaging portion 423 and the latching member 50 . More specifically, the protruding portion 426 During the moving process, the first battery 20 is forced to move along the _third axis A3 by pushing against the inclined surface 52 of the latching member 50, and the latching member 50 is pushed up, so that the first battery 20 is in the second braking unit 421. During the moving process, not only is it released from the engagement state, but it is also pushed out of the main body 10 at the same time, which facilitates the user to take out the first battery 20 .

Therefore, through the action of the magnetic element 413 of the first fastener 41 and the Hall sensor 11, the control unit 12 has already started to prepare for the removal of the first battery 20 when the first fastener 41 is actuated, but the first The battery 20 cannot be separated from the main body 10 until the second fastener 42 is actuated, so that sufficient time (that is, the time difference between releasing the engagement state of the first fastener and the second fastener respectively) will give the control unit sufficient response time. ), so that the control unit 12 can switch the battery or close the application program, so as to maintain the normal operation of the portable electronic device.
