Description

Charging interface device and mobile terminal

Background

In the prior art, along with the popularization of the USB TYPEC interface, the plug can be inserted into the socket without distinguishing the front side from the back side, so that the daily plug operation of people is greatly facilitated, and the convenience of the TYPEC interface is reflected. However, since the TYPE C socket supports positive and negative plug identification, the TYPE C interface is designed to identify the type and the plug-in direction of the plug device by designing two CC (configuration channel, channel configuration) signal PINs on two rows of the socket respectively; since the TYPE EC terminal can supply power to an external Device (DFP) and can also support external power supply to charge the local device (UFP), that is, both functions are supported, namely DRP (charge and discharge). The CC signal on the type socket interface of the terminal needs to periodically detect the insertion condition of the external device, so as to determine whether to supply power to the outside or receive power (charge) from the outside, so that the CC signal needs to have a working detection voltage in the state that the terminal is started; since the working voltage is always present on the CC signal of the USB socket, if water is present between the PIN and other adjacent PINs, or other conductive liquids are immersed in the CC signal, for example, in a daily use environment, the terminal often encounters adhesion of water vapor, sweat, even raindrops, etc., and is used for connecting an external Type-C interface metal contact, which is affected by such sewage, electrochemical corrosion is generated between the CC PIN and other PINs in the Type-C interface due to the existence of the voltage, thereby causing corrosion problems of the CC signal and the adjacent PIN, and with the aggravation of the corrosion, the problem of poor contact, etc. may be caused in the USB socket, thereby further causing various related functional anomalies, and affecting the user experience.

Example 1

Fig. 3 is a block diagram of a first embodiment of the charging interface of the present invention. The invention proposes a charging interface device, comprising: the socket module is used for detecting the insertion state of equipment through one grounding pin, the insertion detection module is used for determining the working attribute of the grounding pin according to the insertion state, the power management module is used for determining the detection state corresponding to the channel configuration pin according to the insertion state, and the processing controller module is used for determining the corresponding charging mode according to the detection state.

Specifically, in the present embodiment, by using one of the four ground pins of the type ec socket as a plug-in detection pin, when the plug of the external device is not inserted into the type ec socket, one of the ground pins of the type ec socket at this time is not used as a ground attribute but is used as an insertion detection pin, and a detection signal of a small voltage amplitude (this voltage amplitude is much smaller than the operating voltage of the channel configuration pin) is set on the pin. When the plug of the external device is plugged into the socket, because the four grounding pins on the plug are of the same electrical property and are of the grounding property, the level of the plug-in detection pin on the TYPEC seat is set low, at the moment, the plug-in detection module can identify the plug of the external device, then the processing controller module opens the channel configuration pin to enter a working state, the type of the inserted external device is detected through the channel configuration pin, if the external device is judged to be a charging power supply device, the power switch of the plug-in detection pin on the TYPEC socket is opened, and meanwhile, the plug-in detection pin of the TYPEC is set to be in a power working state, so that the plug-in detection pin resumes the ground reflux function, namely, the plug-in detection pin returns to the inherent definition property of the TYPEC socket.

Also, as described above for example, when the plug of the external device is pulled out of the type ec socket of the terminal, at this time, it is detected by the process controller module that the external device has been pulled out, the power operation state of the insertion detection pin on the type ec socket of the terminal will be turned off, and one of the pins of the type ec socket continues to be configured as the insertion detection pin, thereby waiting for the insertion state detection of the external device.

The charging interface device comprises a socket module, an insertion detection module connected with the socket module, a power management module connected with the insertion detection module and a processing controller module connected with the power management module, wherein the socket module is used for detecting the insertion state of equipment through a grounding pin, the insertion detection module is used for determining the working attribute of the grounding pin according to the insertion state, the power management module is used for determining the detection state corresponding to a channel configuration pin according to the insertion state, and the processing controller module is used for determining a corresponding charging mode according to the detection state. The interface scheme for determining the corresponding working state according to the plug insertion state is realized, so that on one hand, the universality of socket power supply and data transmission is guaranteed, on the other hand, the problem of corrosiveness to pins of the socket is avoided, the equipment failure rate is reduced, and the user experience is enhanced.

Example two

Fig. 4 is a circuit diagram of an insertion detection module of a second embodiment of the charging interface device of the present invention. Based on the above embodiment, optionally, the socket module is further configured to, when no plug is inserted into the socket module, use one of four ground pins in the socket module as the detection pin of the inserted state, and switch the one ground pin from the detection pin to the ground pin when a plug is inserted into the socket module and the charging device is detected to be inserted.

Referring to fig. 4, a circuit diagram of an insertion detection module of a second embodiment of the charging interface apparatus of the present invention is shown. The circuit of the insertion detection module is composed of a comparison circuit (D1R 1R 2), level matching circuits (D2 and R3) and a power channel switching circuit (D3). Wherein D1 is a comparator module, vref is a comparator reference voltage, R1 and R2 are voltage dividing resistors, the divided voltage is higher than Vref, when typec_gnd_plug_in (the input voltage of the ground pin of the socket) is 0, the output of the comparison circuit is turned over, at this time, the output plug_in_det_n of the level matching circuit is also turned over In level polarity, which is used to inform the process controller module that an insertion event occurs currently, and when the Plug of TypeC is pulled out, typec_gnd_plug_in restores the voltage dividing level, the output of the comparison circuit is turned over, at this time, the output plug_in_det_n of the level matching circuit is also turned over In level polarity, which is used to inform the process controller module that an extraction event occurs currently, and when an insertion event occurs, if the system needs a large power of the TypeC interface, the current exceeds a certain value, for example, 5a is 0.75 (i.e. 3 full load current of GND), the process controller module is notified to turn on the power management module D3, i.e. the typec_in_plug_in is also turned on, and the typec_in is configured as a current required to pass through the socket.

It can be seen that in this embodiment, by reasonably multiplexing one ground pin of the TYPEC socket, that is, as a plug identification pin, and designing an insertion detection module of the plug, plug insertion is effectively identified in advance. Under the premise, when the TYPE EC socket is not plugged into the plug, the processing controller module controls the power management module to close the signal of the channel configuration pin, the plug-in detection pin is configured to be low level, the plug-in detection pin is prevented from still working when the TYPE EC socket is not plugged into the TYPE EC socket, the influence of external environments such as water inflow on the pin is effectively avoided, and corrosion between adjacent pins is avoided. Similarly, when it is detected that the plug is plugged into the type ec socket, the process controller module controls the power management module to turn on the signal of the channel configuration pin, so that the power management module enters a working state, identifies the type of the plugged device, and further executes the operation of the subsequent normal charging flow.

In summary, the present embodiment implements an interface scheme for determining a corresponding working state according to a plug insertion state, so that on one hand, universality of socket power supply and data transmission is guaranteed, on the other hand, corrosion problems to socket pins are avoided, equipment failure rate is reduced, and user experience is enhanced.
