[0094] The application discloses a gating circuit device and a charging and discharging device, and relates to the technical field of gating circuit devices. Figures 1 to 14 The gating circuit device and the charging and discharging device are described in detail below.

[0095] In an embodiment of the application, a gating circuit device 500 includes a control circuit module 214, an interface socket and three circuit components; the control circuit module 214 is connected to the three circuit components through the interface socket and detects the connection state of the three circuit components. Figure 1 In an embodiment, the control circuit module 214 is connected to the three circuit components through the interface socket by using conductive lines, and the connection state of the three circuit components is obtained by detecting the conduction or disconnection of the conductive lines.

[0096] As an example, Figure 1In the embodiment shown, the gating circuit device 500 further comprises three interface sockets, the control circuit module 214 is connected to the interface sockets, and the three circuit assemblies are respectively and correspondingly and detachably connected to the three interface sockets. Specifically, the gating circuit device 500 comprises three interface sockets, including a first interface socket 211, a second interface socket 212, and a third interface socket 213; the three circuit assemblies include a first circuit assembly 114, a second circuit assembly 124, and a third circuit assembly 134; the first circuit assembly 114 is detachably connected to the first interface socket 211, i.e., is detachably connected to the first interface socket 211; the second circuit assembly 124 is detachably connected to the second interface socket 212, i.e., is detachably connected to the second interface socket 212; and the third circuit assembly 134 is detachably connected to the third interface socket 213, i.e., is detachably connected to the third interface socket 213; the remaining embodiments are similar and will not be described in detail.

[0097] In the state where the three circuit assemblies are connected to the interface sockets as access terminals, the control circuit module 214 respectively disconnects the outputs of the three circuit assemblies; as an example, as shown in Figure 2 the first circuit assembly 114 is connected to the first interface socket 211, the second circuit assembly 124 is connected to the second interface socket 212, and the third circuit assembly 134 is connected to the third interface socket 213, the control circuit module 214 respectively disconnects the outputs of the first circuit assembly 114, the second circuit assembly 124, and the third circuit assembly 134, which can also be understood as that the control circuit module 214 respectively disconnects the outputs of the first interface socket 211, the second interface socket 212, and the third interface socket 213. In each embodiment, the interface socket can also be referred to as an interface, a socket, a connection terminal, a port, or a connection terminal, etc., for connecting a circuit assembly.

[0098] In the state where at least one of the three circuit assemblies is connected to the interface socket as an access terminal, and at least one is connected to the terminal to be charged 300 as a charging output terminal, the control circuit module 214 turns on the output of the charging output terminal; as an example, as shown in Figure 3 the first circuit assembly 114 is connected to the first interface socket 211 as an access terminal, the third circuit assembly 134 is connected to the third interface socket 213 as an access terminal, and the second circuit assembly 124 is disconnected from the second interface socket 212, and is connected to the terminal to be charged 300 as a charging output terminal, in this state, the control circuit module 214 turns on the output of the charging output terminal, i.e., turns on the second circuit assembly 124, i.e., turns on the first interface socket 211 and / or the third interface socket 213, and controls the charging output of the second interface socket 212 through the corresponding line, i.e., wire.

[0099] In the state that at least one of the three circuit components is connected as the access terminal, and at least one of the charging adapters 400 is connected as the charging input terminal, the control circuit module 214 turns on the input of the charging input terminal; for example, as shown in Figure 4 In the state that the first circuit component 114 is disconnected from the first interface socket 211, the second circuit component 124 is connected to the second interface socket 212 as the access terminal, the third circuit component 134 is disconnected from the third interface socket 213, and the first circuit component 114 is connected to the charging adapter 400 as the charging input terminal, the control circuit module 214 turns on the input of the charging input terminal, i.e. turns on the first circuit component 114, i.e. turns on the first interface socket 211 and the second interface socket 212, and controls the charging input of the second interface socket 212 through the corresponding line, i.e. the wire.

[0100] Alternatively, another embodiment is as shown in Figure 5 In the state that the first circuit component 114 is disconnected from the first interface socket 211 and connected to the terminal 300 to be charged as the charging output terminal, the second circuit component 124 is disconnected from the second interface socket 212 and connected to the charging adapter 400 as the charging input terminal, and the third circuit component 134 is connected to the third interface socket 213 as the access terminal, the control circuit module 214 turns on the input of the charging input terminal, i.e. turns on the second circuit component 124, i.e. turns on the second circuit component 124 and the third interface socket 213, so that the control circuit module 214 controls the second circuit component 124 to perform the charging input through the third interface socket 213 through the corresponding line; and the control circuit module 214 turns on the output of the charging output terminal, i.e. turns on the first circuit component 114, i.e. turns on the first circuit component 114 and the third interface socket 213, so that the control circuit module 214 controls the first circuit component 114 to perform the charging output through the third interface socket 213 through the corresponding line while performing the charging input. The remaining embodiments are similar and will not be described in detail.

[0101] Such a structure design, through the cooperation of the control circuit module 214, the interface socket and the three circuit components, only needs to simply detect the connection state of the three circuit components to obtain the application state of the three circuit components, including the access terminal, the charging output terminal and the charging input terminal, and the control circuit module 214 can select to turn on or cut off the input and output of the circuit component, thereby providing a gating circuit design applicable to bidirectional charging and discharging. In use, the charging work or the discharging work can be performed without repeatedly switching the connection mode of the circuit component, thereby simplifying the charging and discharging use mode, and also being beneficial to reducing the plugging and unplugging frequency of the wire, and further ensuring the service life of the product.

[0102] In one of the embodiments, the control circuit module 214 conducts the output of the access end when two of the three circuit components are the access end and the other is the charging output end, or conducts the input of the access end when two of the three circuit components are the access end and the other is the charging input end; as an example, as shown in Figure 3 the first circuit component 114 accesses the first interface socket 211 as the access end, the third circuit component 134 accesses the third interface socket 213 as the access end, the second circuit component 124 is unplugged from the second interface socket 212 and accesses the terminal to be charged 300 as the charging output end, and the control circuit module 214 conducts the output of the first circuit component 114 and / or the third circuit component 134; that is, the first circuit component 114 and / or the third circuit component 134 are used as the output circuit.

[0103] Alternatively, the first circuit component 114 accesses the first interface socket 211 as the access end, the third circuit component 134 accesses the third interface socket 213 as the access end, the second circuit component 124 is unplugged from the second interface socket 212 and accesses the charging adapter 400 as the charging input end, and the control circuit module 214 conducts the input of the first circuit component 114 and / or the third circuit component 134; that is, the first circuit component 114 and / or the third circuit component 134 are used as the input circuit. The remaining embodiments are similar and will not be described in detail.

[0127] In one of the embodiments, a charging and discharging device 200 as shown in Figure 17 includes a battery module 215 and a gating circuit device 500; wherein the gating circuit device 500 is any embodiment of the gating circuit device 500; and the control circuit module 214 of the gating circuit device 500 is connected to the battery module 215. As an example, in this embodiment, the charging and discharging device 200 further includes a charging and discharging equipment body 210, and the control circuit module 214 and the battery module 215 are both arranged in the charging and discharging equipment body 210, or the control circuit module 214 and the battery module 215 are both part of the charging and discharging equipment body 210, that is, the charging and discharging equipment body 210 includes the control circuit module 214 and the battery module 215. The charging and discharging device 200 adopts the gating circuit device 500, and thus has the related advantages of the corresponding embodiments of the gating circuit device 500, which are not repeated here.

[0128] In one of the embodiments, as shown in Figure 18 , the charging and discharging device 200 further includes a connecting wire 100, and the connecting wire 100 includes three connecting parts, and the three circuit components are respectively and correspondingly arranged in the three connecting parts. In this way, one composite connecting wire 100 can be used to realize the connection of the three interface sockets.

[0129] The specific circuits of the charging and discharging device 200 and the gating circuit device 500 are described below with Figures 10 to 16 as an example.

[0130] The control channel switching circuit innovatively adopts two analog switches in cooperation to form a MOS structure to switch the control channel, thus saving the MCU and reducing the cost compared with the traditional design. Moreover, the double analog switch scheme is conducive to the switching of the control channel, that is, the fast charging and the general charging can be quickly switched. Since the double analog switch scheme is adopted, the switching speed is faster and the safety is higher compared with the MCU control scheme.

[0131] The control channel reset circuit is also innovatively adopted. The control channel reset circuit adopts six field effect transistors to switch the power line, replaces the function of the MCU in the traditional design, realizes the fast reset of the CC, and achieves the function of waking up the mobile phone as soon as it is inserted. In the following example, the first circuit component 114 is a circuit component with a Lightning interface, and the second circuit component 124 and the third circuit component 134 are circuit components with a Type-C interface. When the Type-C2 is inserted into the terminal to be charged 300, such as a mobile phone, the charging line pull-down resistor R12 is pulled down to GND through the T pin, the wake-up charging and discharging device 200, such as a mobile power supply, that is, a power bank, outputs to charge the mobile phone, and after the mobile phone is pulled out, the power bank automatically enters sleep mode to reduce power consumption.

[0132] The power line switching circuit is also innovatively adopted. In this way, when the TYPE-C2 is connected to the mobile phone and the Lightning is not connected to the mobile phone, the Lightning port output connected to the mobile phone is automatically cut off, and when the TYPE-C2 is not connected to the mobile phone, the TYPE-C2 port output is automatically cut off, so that when one-way high-voltage fast charging is output, the other way is in a safe state without output.

[0133] In addition, when the Lightning and the TYPE-C2 are connected to the terminal to be charged 300, that is, the charging device at the same time, the power switching circuit can switch the output from the single high-voltage fast charging state to the 5V output, so as to realize the dual-way safe output; when any one of the Lightning and the TYPE-C2 is pulled out, the switching circuit will switch back to the single high-voltage fast charging state, thereby improving the charging speed of the charging device.
