And the output detection module 102 is provided with a second connection end for the electric equipment.
And a first input end of the first communication module 103 is connected with a first output end of the input detection module 1011 of the first communication module 103.
A processing unit 104, a first input end of the processing unit 104 is connected with an output end of the first communication module 103, and a first output end of the processing unit 104 is connected with a first input end of the output detection module 102.
A first input end of the voltage conversion module 105 is connected to the second output end of the processing unit 104, a second input end of the voltage conversion module 105 is connected to the second output end of the input detection module 1011, and an output end of the voltage conversion module 105 is connected to the second input end of the output detection module 102.

In this embodiment, the first connection end of the input detection module 1011 is used for connecting the charger 201 shown in fig. 3. A first output terminal of the input detection module 1011 may be a data output terminal through which a charging protocol signal of the charger 201 may be transmitted to the first communication module 103. A second output terminal of the input detection module 1011 may be a voltage output terminal through which the protocol voltage of the charger 201 may be transmitted to the voltage conversion module 105.
In this embodiment, the second connection end of the output detection module 102 is used to connect to an electric device 30, which may be an electronic device such as a mobile phone, a tablet computer, a notebook computer, a palm computer, and a wearable device.
In this embodiment, the processing unit 104 may be an MCU control module. The first communication unit 103 stores charging protocols of chargers in various states, such as, but not limited to, charging protocols of the charger 201, the charger 202, and the charger 203 shown in fig. 2. The second communication unit 106 stores charging protocols of the electric device 30 in various states.
In this embodiment, as shown in fig. 1 and 2, the voltage conversion method based on the voltage conversion device 10 includes the following steps S2100 to S2500:
in step S2100, when the input detection module 1011 detects that the charger 201 is inserted into the first connection terminal, the input detection module transmits the first charging protocol signal S1 of the charger 201 to the first communication module 103.
In step S2100, after the charger 201 is connected to the voltage conversion device 10 through the first connection end of the input detection module 1011, the charging protocol signal S1 of the charger 20 is sent to the first communication module 103 through the first output end of the input detection module 1011.
In step S2200, the first communication module 103 decodes the first charging protocol signal S1 and transmits a first signal S2 indicating the protocol voltage of the charger 20 to the processing unit 104.
In step S2200, since the first communication module 130 stores the information of the charging protocols of different chargers in advance, the information of the charging protocols at least includes the protocol voltage of the charger, when the first input end of the first communication module 103 receives the charging protocol signal of the charger 201 sent by the input detection module 1011, and the decoding handshake succeeds, the signal indicating the protocol voltage of the charger 201 is sent to the processing unit 104 through the output end of the first communication module 103.
It can be understood that, if a matching charging protocol can be found in different pre-stored charging protocols for the currently received first charging protocol signal s1, the signal indicating the protocol voltage of the charger 201 may be directly sent to the processing unit 104; if the currently received first charging protocol signal s1 cannot find a matching charging protocol in the different pre-stored charging protocols, the first charging protocol signal s1 may be stored first, and then the signal indicating the protocol voltage of the charger 201 is sent to the processing unit 104.
In step S2300, the output detection module 102 sends the second charging protocol signal S4 of the electric equipment 30 to the second communication module 106 when detecting that the electric equipment 30 is plugged into the second connection terminal.
In step S2300, after the electrical device 30 is connected to the voltage conversion device 10 through the second connection end of the output detection module 102, the charging protocol signal S4 of the electrical device 30 is transmitted to the second communication module 106 through the output end of the output detection module 102.
In step S2400, the second communication module 106 decodes the second charging protocol signal S4 and sends a second signal S5 indicating the protocol voltage of the electric device 30 to the processing unit.
In this step S2400, since the second communication module 130 stores the information of the charging protocols of the different electric devices in advance, and the information of the charging protocols at least includes the protocol voltage of the electric device, when the first input end of the second communication module 106 receives the charging protocol signal of the electric device 30 sent by the output detection module 102, and the decoding handshake succeeds, the signal indicating the protocol voltage of the electric device 30 is sent to the processing unit 104 through the output end of the second communication module 106.
In step S2500, the processing unit 104 sends the first conversion control signal S6 to the voltage conversion module 105 in case of receiving the first signal S2 and the second signal S5, and the voltage conversion module 105 converts the protocol voltage of the charger 201 into the protocol voltage of the electric device 30 according to the first conversion control signal S6.
The first switching control signal may be a step-up or step-down control signal. A Buck/Boost circuit is built in the voltage conversion module 105 to convert the protocol voltage of the charger 201 into the protocol voltage of the electric device 30 by using the Buck/Boost circuit.
In step S2500, after the first input end and the second input end of the processing unit 104 receive the first signal S2 and the second signal S5, respectively, the first conversion control signal S6 is sent to the voltage conversion module 105 through the second output end of the processing unit 104, and the voltage conversion module 105 converts the protocol voltage of the charger 201 into the protocol voltage of the electric device 30 according to the first conversion control signal S6, and outputs the protocol voltage to the output detection module through the output end of the voltage conversion module 30 to perform fast charging on the electric device 30.
In the embodiment of the invention, the voltage conversion equipment independent of the electric equipment and the charger is provided, and the voltage conversion equipment at least comprises a communication module, a processing unit and a voltage conversion module, wherein the communication module decodes and identifies the charging protocol of the connected charger and the charging protocol of the connected electric equipment, and sends a second signal indicating the protocol voltage of the charger and a second signal indicating the protocol voltage of the electric equipment to the processing unit, and then the processing unit sends a conversion control signal to the voltage conversion module, so that the voltage conversion module converts the charging protocol of the charger into the protocol voltage of the electric equipment and supplies the protocol voltage to the electric equipment for charging.
In one embodiment, the processing unit 104 further sends a second conversion control signal s3 to the voltage conversion module 105 in case of receiving the first signal, and converts the protocol voltage of the charger 201 into the preset voltage of the charger 201 according to the second conversion control signal s3 through the voltage conversion module 104.
The preset voltage may be 5V, and may also be other values, which is not limited herein.
The second switching control signal may be a step-up or step-down control signal.
In this embodiment, after receiving the first signal s2, the first input end of the processing unit 104 sends a second conversion control signal s3 to the voltage control module 105, and the Buck/Boost circuit built in the voltage conversion module 105 converts the protocol voltage sent by the second input end of the input detection module 1011 into a preset voltage, for example, 5V, according to the second conversion control signal s3, and outputs the preset voltage.
For example, in the case where the output detection module 102 does not detect that the useful electrical device 30 is inserted into the second connection terminal, the voltage conversion device 10 enters a standby state.
For another example, in a case where the output detection module 102 detects that the electric equipment 30 is plugged into the second connection terminal, the above steps may be performed to transmit the second charging protocol signal of the electric equipment 30 to the second communication module 106, the second communication module 106 decodes the second charging protocol signal and transmits a second signal indicating the protocol voltage of the electric equipment 30 to the processing unit 104, at this time, the processing unit 104 releases the standby state and transmits the first conversion control signal to the voltage conversion module 105, and the voltage conversion module 105 converts the above preset voltage into the protocol voltage of the electric equipment 30 and starts the rapid charging according to the first conversion control signal.

The second communication module 106 decodes the second protocol signal s4 and sends a second signal s5 indicative of the protocol voltage of the powered device 30 to the processing unit 104.
The processing unit 104 sends a first conversion control signal s6 to the voltage conversion module 105 upon receiving the feedback signal m3 and the second signal s5, and the voltage conversion module 105 converts the combined protocol voltage of the charger 301, the charger 302, and the charger 303 into the protocol voltage of the electric device 30 according to the first conversion control signal s 6.
According to this embodiment, when all the protocols of the 3 sets of chargers 201, 202, and 203 have been successfully handshake, and the 3 sets of independent power loop input terminals and the combined power loop output terminal are all turned on, the function of power superposition P = P1+ P2+ P3 is realized, and higher power can be output to charge the electric device 30.
In one embodiment, as shown in fig. 1, the output detection module 102 includes an output port 1021 and an output port detection unit 1022.

It will be appreciated that the input detection module may also comprise an input port and an input port detection unit (not shown in the figure).
In one embodiment, the voltage conversion device 10 further comprises a data transmission module 108, the data transmission module 108 comprising a wifi module and/or a bluetooth module.
A first output end of the data transmission module 108 is connected to a second input end of the first communication unit 103, a second output end of the data transmission module 108 is connected to a second input end of the second communication unit 106, and a third output end of the data transmission module 108 is connected to a third input end of the processing unit 104.
In this embodiment, the power conversion device 10 has a built-in Wifi function, and after the Wifi activation state (the Wifi function can be selected to be turned on/off by an external key of the voltage conversion device 10) is successfully matched with the device having the Wifi receiving function, the intelligent control and the update function of the charging protocol program in the charging process can be realized. For example, a wifi function switch (ON) of the voltage conversion equipment is pressed, the key switch is connected with an external power supply, the external power supply supplies power to the wifi module after the key is pressed so that the wifi module can be activated, and after the equipment receives a wifi signal and is successfully matched, the voltage conversion equipment and the equipment establish a signal transmission path.
In one example, the voltage conversion device 10 may implement an automatic update of the charging protocol program.
The data transmission module 108 receives the first charging protocol or the second charging protocol and sends the first charging protocol to the first communication module 103, or sends the second charging protocol to the second communication module 106.
The first communication module 103 decodes the first charging protocol signal and stores the information of the first charging protocol obtained after decoding, or the second communication module 106 decodes the second charging protocol signal and stores the information of the second charging protocol obtained after decoding.
As can be seen from the above, the first communication module 103 stores information of the first charging protocol of each charger, and the information of the first charging protocol at least includes the protocol voltage of the charger; the second communication module 106 stores information of a second charging protocol of each electric device, where the information of the second charging protocol at least includes a protocol voltage of the electric device. Therefore, when the first charging protocol information currently received is not included in the plurality of pieces of first charging protocol information pre-stored by the first communication module 103, the first charging protocol information may be stored (written); similarly, the second charging protocol information may be stored (written) when the currently received second charging protocol information is not included in the plurality of second charging protocol information pre-stored by the second communication module 106.
Taking the data transmission module 108 as a Wifi module as an example, when the original charging protocol program of the voltage conversion device 10 needs to be updated or a new charging protocol program needs to be added, the update may be implemented through a data transmission function, for example, after the Wifi module receives a charging protocol data packet sent by a charger or an electric device, the data packet is sent to the first communication module 103 and the second communication module 106, respectively.
The first communication module 103 and the second communication module 106 decode the charging protocol data packet of the charger or the electric equipment after receiving the charging protocol data packet, store the decoded charging protocol of the charger into the first communication module 103, and store the decoded charging protocol of the electric equipment into the second communication module 106.
After the data is successfully written in, the voltage conversion device 10 is successfully updated or a new charging protocol is added, and when a charger or a consumer is accessed next time, the charging protocol detected by the input detection module or the output detection module can be matched with the latest charging protocol of the first communication module 103 and the second communication module 106.
In one example, intelligent control of the charging process may be implemented.
Illustratively, wifi related functions are realized through a device UI interface, which is exemplified by intelligent charging control, and after a UI interface charging control instruction is sent, a wifi module receives the control instruction and sends the control instruction to the processing unit 104; if the instruction belongs to immediate turn-off charging, the processing unit 104 immediately sends a turn-off instruction to the output port 1021, and turns off the power supply of the voltage conversion device 10 to the electric equipment 30; if the instruction is to turn off the charging after the timing T0, the processing unit 104 starts the timer function of its own after receiving the signal, and immediately sends a turn-off instruction to the output port 1021 after the countdown T0 is reached, so as to turn off the power supply of the voltage conversion device 10 to the electric equipment 401.
In this embodiment, the voltage conversion device realizes the charging switch control of the electric device through the wifi module function, and can also update or add a new charging protocol at any time.
