[0019] See also Figure 1 , Figure 1 A multifunctional mobile power supply (hereinafter referred to as mobile power supply) is shown, which can conveniently power electronic devices that are not equipped with rechargeable batteries. The mobile power supply includes:

[0020] A controller 10 and an integrated interface 20 connected to the controller 10;

[0021] The integrated interface 20 is used to output a driving voltage to the electronic device when detecting that an electronic device is connected, so as to drive the electronic device to communicate with the controller 10;

[0022] The content of the communication includes data such as the device type and operating voltage sent by the electronic device, as well as the processing of the data by the mobile power supply.

[0023] The controller 10 is used to identify the device type and working voltage of the electronic device according to the communication content, and to power the electronic device according to the identified working voltage of the electronic device through the integrated interface 20, that is, to output the working voltage from the integrated interface 20 to the electronic device.

[0024] Among them, the driving voltage is the default output voltage of the mobile power supply, such as 5V (volts), which is used to drive the electronic device to communicate with the mobile power supply. The communication can be initiated by the mobile power supply, and a communication request is sent to the electronic device through the controller 10, or the controller of the electronic device actively sends communication information, including the device type of the electronic device and the voltage required for operation.

[0025] The controller 10 may be a microcontroller unit (MCU) or a single-chip microcomputer or other chip with corresponding data processing capabilities.

[0026] In this embodiment, the multifunctional mobile power supply includes a controller and an integrated interface connected to the controller. The integrated interface is used to output a driving voltage to the electronic device when detecting that an electronic device is connected, so as to drive the electronic device to communicate with the controller. The controller is used to identify the device type and the operating voltage of the electronic device according to the content of the communication, and to power the electronic device according to the operating voltage through the integrated interface. It can be applicable to electronic devices of different types and different operating voltages, and can power electronic devices that do not have a charging function, and saves the cost of configuring rechargeable batteries in the electronic device and the purchase cost of the user.

[0027] See also Figure 2 , wherein the integrated interface 20 may include: a group of external power supply interfaces 21 and a group of communication interfaces 22;

[0028] The external power interface 21 has a voltage output function and can be used to power the electronic device;

[0029] The communication interface 22 has a communication function and can be used for the controller 10 to communicate with the electronic device.

[0030] The integrated interface 20 may specifically be a 4P interface, wherein a group of 2P interfaces is used as a group of external power interfaces 21 , and another group of 2P interfaces is used as a group of communication interfaces 22 .

[0031] It can also be a 3P interface with a common ground, or a multi-P interface that further includes other interfaces for sharing current and voltage, so as to realize a high-power interface, such as 2P of which can realize 5A (ampere) current, and another 2P can realize 8A or 9A current.

[0032] In another embodiment, the integrated interface 20 may also be a single interface having both a power supply function and a communication function. The power supply function is used to supply power to the electronic device, and the communication function is used to communicate with the electronic device.

[0033] The integrated interface 20 may specifically be a USB (Universal Serial Bus) interface.

[0034] See also Figure 3 The mobile power supply further includes: a housing 101; a charging port 30 and a magnetic module arranged on the housing 101; a power electronic switch 50, a charge and discharge management chip 60, an over-discharge protection chip 70 and a power inductor 80 arranged in the housing 101;

[0035] The integrated interface 20 is disposed on the housing 101 , and both the integrated interface 20 and the charging port 30 are exposed from the housing 101 for access by electronic devices.

[0036] The magnetic module may be a magnet, which is used to adsorb the mobile power supply onto the electronic device through magnetic force to prevent it from falling off during the power supply process, thereby causing inconvenience in power supply.

[0037] Specifically, Figure 3 As shown, the magnetic module includes a magnet N pole 41 and a magnet S pole 42, which are respectively arranged on both sides of the integrated interface 20. The housing of the electronic device is also provided with a magnetic module, which also includes a magnet N pole and a magnet S pole. The principle of mutual repulsion of the same poles is used to match the polarities of the two magnets with the polarities of the two magnets with opposite polarities on the electronic device, so as to magnetically attract the electronic device to the electronic device, and the polarity of the integrated interface matches that of the power supply interface of the electronic device. That is, when the S pole of the magnet of the electronic device is set to correspond to the N pole of the magnet of the mobile power supply, the possibility of reverse connection of the positive and negative poles of the electronic device and the mobile power supply is prevented.

[0038] The charging port 30 may be one or more different types of charging ports, used to charge a connected electronic device with a rechargeable battery. The charging port may be different types of charging ports such as USB-A, TYPE-C, and Lighting.

[0039] The power electronic switch 50 is connected to the controller 10 and is used to output different voltages under the control of the controller 10 so that the integrated interface 20 outputs a working voltage to power the electronic device.

[0040] The over-discharge protection chip 70 is connected to the power electronic switch 50 and the charge and discharge management chip 60;

[0041] The charge and discharge management chip 60 is also connected to the power inductor 80 and the charging port 30;

[0042] The charge and discharge management chip 60 is used to perform the charging function. The charge and discharge management chip 60 needs to perform step-up and step-down according to different protocols. The power inductor 80 is used to perform rectification during the charging process.

[0043] The over-discharge protection chip 70 is used to monitor the battery power and cut off the circuit when the battery power is too low to prevent the battery from being damaged due to over-discharge.

[0044] When the electronic device is connected to the communication interface 22, the electronic device sends its own device type, operating voltage and other information in accordance with the agreed protocol when communicating with the mobile power supply. If the controller 10 detects that the electronic device has sent the device type and operating voltage of the electronic device through the communication interface 22 in accordance with the agreed protocol, the controller 10 is used to power the electronic device through the external power supply interface 21 according to the operating voltage sent by the electronic device.

[0045] In another embodiment, the electronic device has a need to switch the working voltage, and the controller 10 is further used to power the electronic device through the external power interface 21 according to the working voltage requested to switch in the switching voltage signal if a switching working voltage signal is detected by the electronic device through the communication interface 22. For example, when a user adjusts the blowing gear when using a handheld fan, the handheld fan sends a signal to switch the working voltage to the mobile power supply through the communication interface 22. After the controller 10 of the mobile power supply detects the signal sent by the handheld fan, it outputs the working voltage from the external power interface 21 according to the working voltage requested by the signal to power the handheld fan according to the switched gear.

[0046] In another embodiment, the mobile power supply can provide the electronic device with a working voltage according to the user's selection. The mobile power supply also includes an output voltage selection button, and the controller 10 is used to supply power to the electronic device according to the voltage selected by the user through the external power interface 21 if it is detected that the output voltage selection button is operated by the user. The diversity of the working voltage selected by the electronic device can be increased, and the convenience of powering the electronic device can be improved.

[0047] In another embodiment, the mobile power supply may also include a memory, and the historical charging information is stored in the memory. If the controller 10 detects that the output voltage selection button is operated, the device type is requested from the connected electronic device through the communication interface 22, the device type is obtained, and the working voltage corresponding to the device type is searched in the historical charging information, and the working voltage found is compared with the voltage corresponding to the output voltage selection button. If they are the same, the electronic device is powered by the external power supply interface 21 according to the voltage. If they are not the same, no power is supplied and a prompt message is issued to indicate that the output voltage selection button is operated incorrectly. The prompt message can be a text message displayed on the screen of the mobile power supply, a voice message played through the voice module of the mobile power supply, or a buzzer or light is issued by the alarm module of the mobile power supply. Equipment damage caused by manual selection of output voltage errors can be avoided, and the intelligence of the mobile power supply can be improved.

[0048] See also Figure 4 , the embodiment of the present application also provides a multifunctional mobile power system, including: a multifunctional mobile power (hereinafter referred to as mobile power) 100 and an electronic device 200;

[0049] The mobile power source 100 is the multifunctional mobile power source in the above-mentioned embodiments.

[0050] The mobile power supply 100 includes a first controller 102 and an integrated interface 20 connected to the first controller 102. The first controller 102 may be the controller 10 in the above embodiment.

[0051] The electronic device includes a second controller 201 ; the electronic device 200 has an input interface 202 matching the integrated interface 20 .

[0052] The integrated interface 20 is used to output a driving voltage to the electronic device 200 when detecting that the electronic device 200 is connected, so as to drive the electronic device 100 to communicate with the first controller 102;

[0053] The first controller 102 is used to identify the device type and the operating voltage of the electronic device 200 according to the communication content, and to supply power to the electronic device 200 according to the operating voltage through the integrated interface 20 .

[0054] In this embodiment, the multifunctional mobile power system includes a multifunctional mobile power and an electronic device. The multifunctional mobile power includes a first controller and an integrated interface connected to the first controller. The integrated interface is used to output a driving voltage to the electronic device when detecting that an electronic device is connected, and drive the electronic device to communicate with the first controller. The first controller is used to identify the device type and the working voltage of the electronic device according to the content of the communication, and power the electronic device according to the working voltage through the integrated interface. It can be applicable to electronic devices of different types and different working voltages, and can realize powering electronic devices that do not have a charging function, and saves the cost of configuring rechargeable batteries in electronic devices and the purchase cost of users.

[0055] Furthermore, the mobile power supply 100 also includes the charge and discharge management chip 70 and the charging port 30 in the above embodiment.

[0056] The charging management chip 70 supports fast charging of different powers or voltages, such as 5V, 9V, 10V, 11V, 12V and 20V. An external electronic device can be plugged into the charging port to make the charging management IC output the corresponding voltage through the forged protocol.

[0057] The electronic device 200 is connected to the charging port 30 of the mobile power supply 100, and the second controller 201 of the electronic device 200 is used to send forged power supply information to the charging management chip 70, where the forged power supply information includes the device type of the simulated electronic device 200 and the required charging voltage;

[0058] The forged power supply information can be implemented in the form of a forged protocol. The second controller 201 is used to send a forged protocol to the charging management chip 70, which includes the device type of the simulated electronic device 200 and the required charging voltage, so that the charging management chip 70 outputs the required charging voltage through the charging port 30 to charge the electronic device 200, instead of adapting the charging voltage corresponding to the device type according to the actual device type of the electronic device 200.

[0059] The charging management chip 70 supplies power to the electronic device 200 through the charging port 30 according to the simulated required charging voltage.

[0060] The electronic device can request the charging management chip of the multi-functional mobile power supply to output any charging voltage it supports in the form of a forged protocol, thereby improving the flexibility and adaptability of charging.

[0061] In another embodiment, see Figure 5 , the electronic device 200 further includes a voltage regulating module 203;

[0062] Compared with the above-mentioned embodiments, the mobile power supply 100 only provides a set of external power supply interfaces 22 for power output, or only uses the power supply function of the integrated interface 20, and does not communicate with the electronic device. If the controller 102 detects that the external power supply interface 22 is connected to the electronic device 200, the mobile power supply 100 is controlled to provide a uniform driving voltage for the electronic device 200 through the external power supply interface 22, which is used to drive the second controller 201 to work. The driving voltage can be the driving voltage in the above-mentioned embodiment, or it can be a driving voltage of other values.

[0063] If the working voltage of the electronic device 200 does not match the driving voltage, the slave controller 201 of the electronic device 200 controls the voltage regulation module 203 to increase or decrease the voltage according to the working voltage requirement of the electronic device 200 itself based on the working voltage, so that the driving voltage matches its own working voltage, thereby improving the adaptability to the mobile power supply.

[0064] The voltage regulating module 203 may be a buck-boost circuit, which can achieve voltage boost or voltage reduction, and the specific circuit structure is not limited.

[0065] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0066] The above is a description of the multifunctional mobile power supply and system provided by the present application.
