Compared with the prior art, the charging device adds a control unit and a switch unit to the conventional conventional charging unit, and operating the switch unit can trigger the control unit to form a conductive charging circuit to give - Rechargeable battery charging of the configurable electronic device. When the charging battery is fully charged, the control unit is triggered to be turned off, thereby automatically stopping the charging; the battery is charged and the charging device is also self-competing. Therefore, the charging device not only helps to prolong the service life of the rechargeable battery and itself, but also saves energy. [Embodiment] Referring to Fig. 1, a preferred embodiment of the present invention provides a charging device, which is preferably used for charging a rechargeable battery 1 to an electronic device such as a mobile phone or a PDA. The charging device 100 includes a substrate 30 and a conventional charging unit 4, a control unit 50, and a switching unit 60 disposed on the wire board 30. The substrate 30 can be a printed circuit board (PCB), a flexible circuit board (FPC), or the like, and is used to carry the internal circuit components of the charging device. The necessary electrical connection between the circuit components. The $ gauge charging unit 40 is a conventional charging circuit that can be connected to a conventional charging power source 70 for rectifying, filtering, voltage regulating, etc., of the externally provided charging power source 7 , to facilitate charging. Battery 10 provides a stable charging voltage. The control unit 50 can be an electronic control device such as a relay (Reiay) for controlling the conduction or _ of the circuit of the conventional charging unit 40. In the present embodiment, the control unit 50 is a miniature relay including a coil 52 and a touch switch %. One end of the line 4 201039533 circle 52 is electrically connected to the above-mentioned conventional charging unit 40. The __ 54 ; _ = - is transferred to one end of the opening and closing unit 6 , and is connected to the other end of the conventional charging unit 4 and the opening unit 60, The electrically connected terminals of the charging power sources 70 and 54 can be made of a ferromagnetic material having elasticity: the control of the magnitude of the current of the touch switch can be known. /, closing and closing by the coil 52 ❹ generates a magnetic force to the touch switch 54. When the magnetic field is formed to facilitate the description, the current in the if circle 52 reaches a predetermined value (for the magnetic relaxation (four) two is called the pull-in current), the coil 52 generates 54 -, Lai: (4) The charging unit that is transferred to the surface is charged to the rechargeable battery. 2 'When there is no current in the coil 52 or the rechargeable battery K is in the state of / month, the current is less than 4 γ _ 52 έ ^ " The current is less than the above-mentioned pull-in current, which is When the __54 is in the _ state, the touch switch 4 is automatically disconnected due to its own elasticity, thereby disconnecting the conventional charging unit 4 〇 to stop charging the rechargeable battery 1 。. The 兀60 can be a conventional switching device such as a dust switch, which can be set in the form of a button, a face test (10) read _ (four), and a button for the user of the button switch is electrically connected to the The other end of the charging power source 7〇 and the touch switch μ are electrically connected to the other ends of the conventional charging unit 4〇 and the touch switch. When the charging power source 7〇 is charged and the charging battery 1〇 is charged Pressing the switch unit 60', a path is formed between the charging power source 70, the conventional charging unit 40, the coil 52 and the rechargeable battery 10, and the current in the path increases instantaneously, and the current flowing through the coil 52 is greater than the suction H_52 generates electromagnetic force by the electromagnetic secret to make the touch open The closing 54 is automatically closed. It can be understood that when the rechargeable battery 1 () is not connected to the charging 5 201039533, both the electric unit 40 and the coil 52 are in an open state, and even if the device 100 is not pressed when the switching unit 6 is pressed, the charging power source 70 In the conventional coiling, no current flows through the coil 52 to form a charging circuit. When the charging device 1 is used to charge the rechargeable battery 1 首先, first, the ^== is in the _ state. The charging battery 10 is connected to the charging device 100, and the second "electric device 100 turns on the external charging power source 7 to provide charging power. Then, the above-mentioned unit 6G' is the charging power source 7G, the neo charging unit, the coil 52, and ❹=Electricity, a charging circuit is formed between 10'. The charging technique is used to provide a stable voltage to the rechargeable battery. At this time, the current flowing through the coil 52 is instantaneously increased, so that the current flowing through the coil 52 is greater than The above-mentioned pull-in current, _52 generates a sufficiently large electromagnetic force due to electromagnetic induction to make the touch-off 54 self-smooth. After that, the unit 6 is released, then the charging power source 70, the touch switch 54, the conventional Charging unit 4〇, Another charging circuit is formed between the coil 52 and the rechargeable battery 10. Thus, the charging device 1 can charge the rechargeable battery 10. When the charging battery 10 is about to be fully charged, the charging power source 7 The current between the touch switch 54, the conventional charging unit 40, the coil 52, and the rechargeable battery 1 is gradually changed to h. When the rechargeable battery 10 reaches the full state, the current flowing through the coil 52 is converted to be much smaller than the above-mentioned pull-in. The current, the magnetic field generated by the coil 52 is weakened, and the electromagnetic force is insufficient to keep the touch switch 54 in the closed state. The touch switch 54 is automatically disconnected due to its own elasticity. At this time, the charging power source 70, the touch switch 54, the conventional charging unit. The charging circuit formed between the coil 52 and the rechargeable battery 10 is disconnected, that is, the charging of the rechargeable battery 1 is stopped to save power and protect the rechargeable battery 10. In addition, since the switching unit 6 is in a disconnected state, the charging device 100 is also stopped to reduce useless power consumption and usage loss. 6 201039533 The charging I set in the original conventional charging single rechargeable battery 1G 充电 to charge the battery 1G of the portable electronic device. When and after the “electricity”, the unit 5 can be self-assembled, charging from the rechargeable battery 10, and the charging device is fine: setting = is beneficial to extend the rechargeable battery 峨 ^ to better save energy.
