Embodiment 1

[0039] figure 1 It is a schematic diagram of a charger shown according to an exemplary embodiment. The charger includes a charging circuit module 101, a control module 102 connected to the charging circuit module 101, a charging line interface 103, a charging switch module 104, and a detection switch module 105. The charging line interface 103 includes a voltage line interface 103a, a data line interface 103b, ID line interface 103c and ground line interface 103d.

[0040] The charger is used for charging or supplying power to electronic equipment. It should be noted that, for the convenience of description, the electronic device is referred to as the device to be charged hereinafter, but in fact, since the charger can be used to charge the electronic device, it can also be used to supply power to the electronic device, and thus the device to be charged The device may also be a device to be powered, and the present disclosure does not limit the specific use of the charger fo...

Embodiment 2

[0051] figure 1 The charger shown can realize the effect that only when the charger is connected to the device to be charged, the charger outputs the charging voltage, and when not connected, the charger does not output the voltage. In order to achieve this effect more conveniently, in another embodiment of the present disclosure, the charging cable has another implementation manner. Combine below image 3 This other implementation will be described.

[0052] image 3 It is a schematic diagram of a charger shown according to an exemplary embodiment. The charger includes a charging circuit module 301, a control module 302 connected to the charging circuit module 301, a charging line interface 303, and a charging switch module 304. The charging line interface 303 includes a voltage line interface 303a, a data line interface 303b, and an ID Wire interface 303c and ground wire interface 303d. The control module 302 is connected to the data line interface 303b, the control mod...

Abstract

The invention provides a charger, electronic equipment and a charging method, and belongs to the field of electronic technologies. According to the charger, a control module (102) is connected with a charging switch module (104), the charging switch module (104) is arranged between a charging circuit module (101) and a voltage line interface (103a), the control module (102) is connected with a detection switch module (105), and the detection switch module (105) is arranged between an ID line interface (103c) and a ground wire interface (103d). According to voltage change in a data line interface (103b), the control module (102) controls ON / OFF states of the charging switch module (104) and the detection switch module (105). According to the invention, the charger does not output a charging voltage unless the charger is connected with a device to be charged, and the using safety of the charger is improved.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to a charger, an electronic device and a charging method. Background technique [0002] With the development of electronic technology, electronic devices such as mobile phones and notebook computers have become indispensable tools in people's production and life anytime and anywhere. [0003] Currently, chargers are generally used to charge or supply power to electronic devices. Use the charger to convert the 220V AC voltage into a voltage below the safe threshold, and connect the electronic device with the voltage below the safe threshold to charge or supply power to the electronic device. However, when the charger breaks down, the charger may be connected with a voltage exceeding the safety threshold of the human body. At this time, if the charger is touched, it will be dangerous. Contents of the invention [0004] In order to overcome the problems existing in rel...
