Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, an embodiment of the present application provides a power supply apparatus, including:

the first connecting end 1 can be connected with a direct current power supply or an alternating current power supply;

the second connecting end 2 can be connected with equipment to be powered;

the first conversion module 3 is connected between the first connecting end 1 and the second connecting end 2, can process the obtained direct current into a current form matched with the equipment to be powered and transmits the direct current to the equipment to be powered through the second connecting end 2;

and the second conversion module 4 is connected between the first connecting end 1 and the second connecting end 2, and can process the obtained alternating current into a current form matched with the equipment to be powered so as to be transmitted to the equipment to be powered through the second connecting end 2.

For example, the first connection end 1 of the embodiment of the present application may be a connector, such as a power plug, or an interface, and is connected to a power source through other devices. The second connection end 2 may be a connector, such as a USB connector, or an interface, which may be determined according to the specific structure of the connection end disposed on the device to be connected. The first conversion module 3 and the second conversion module 4 may be respectively formed by two sets of circuits disposed on a circuit board, or may be respectively formed by two circuit boards each having a circuit disposed thereon in a matching manner, or may be formed by two devices capable of respectively converting ac power into dc power and regulating dc power to form dc power with different voltages, which is not unique. When a user uses an electronic device such as a notebook computer, a mobile phone, a tablet computer, and the like at home, an office, and the like, the power supply device of the embodiment of the present application can be connected to the electronic device, and then connected to a mains supply, and the direct current that can be directly used is obtained through the power supply device to supply the electronic device to normally operate, and when the user uses the electronic device such as the notebook computer, the mobile phone, the tablet computer, and the like at a factory, the power supply device of the embodiment of the present application can be connected to the electronic device, and then connected to an industrial power supply, and the direct current that can be directly used is obtained through the power supply device to supply the electronic device to normally operate, so that the user can easily realize the normal use of the electronic device at any place and any power supply (such as the mains supply and the industrial power supply) through only one power supply device, and does not need to separately use different power supply devices to realize the normal use of different power supplies as in the prior To ensure proper operation of the electronic device.

In summary, the power supply device in the embodiment of the present application has the beneficial effects that at least, the power supply device can realize the function of converting ac power into dc power, and can simultaneously realize the voltage transformation of dc power, so that the accessed dc power can be directly supplied to the device through the voltage regulation, and a user does not need to adopt two independent power supply devices to complete power supply, thereby providing convenience for the user to use the electronic device in different occasions.

Further, the power supply device in the embodiment of the present application further includes

A switch 5 connected to the first connection terminal 1 and the first and second conversion modules 3 and 4, respectively; the switch 5 can match the received current to the first conversion module 3 or the second conversion module 4 according to the type of current received by the first connection 1.

For example, the switch 5 has a first terminal and a second terminal, the first terminal is connected to the first connection terminal 1, the second terminal is connected to the first conversion module 3 and the second conversion module 4 through two lines, respectively, or the switch 5 may also have a third terminal, and the first conversion module 3 and the second conversion module 4 are connected to the second terminal and the third terminal of the switch 5, respectively. When the switch 5 receives ac power from the first connection end 1, it can identify the ac power and transmit the ac power to the second conversion module 4, and when the switch 5 receives dc power from the first connection end 1, it can identify the dc power and transmit the dc power to the first conversion module 3. Alternatively, the switch 5 may be a manual switch 5, that is, it is provided with a switch, and a user can manually operate the switch according to whether the commercial power source or the industrial power source is connected, so that the switch 5 correspondingly transmits the current to the first conversion module 3 or the second conversion module 4.

Specifically, referring TO fig. 3, the AC TO DC region shown in the figure can be regarded as a portion of the second conversion module 4 for converting AC power into DC power, and the DC TO DC region is a portion of the first conversion module 3 for converting DC power after voltage regulation. When the current passes through the first connection 1 (not shown), it enters the switch 5, and the switch 5 determines, for example, whether it is ac or dc, for example, by the waveform of the input current voltage, and transmits the current to the first conversion module 3 in the case of dc, or transmits the current to the second conversion module 4 in the case of ac.

Further, an adjusting unit for adjusting the value of the dc voltage received from the first connection terminal 1 to be adapted to the voltage required by the device to be powered is disposed in the first converting module 3 in the embodiment of the present application.

For example, the power supply device is connected to an industrial power supply, the obtained current voltage is 220v or 110v, and the voltage required by the electronic equipment connected to the power supply device may be only 30v, so that the voltage received by the power supply device cannot be directly used by the electronic equipment at this time, and the received voltage needs to be adjusted to avoid that the electronic equipment is always operated in a high-voltage state, which affects the service life of hardware of the electronic equipment. In order to ensure that the electronic device can normally operate, in the embodiment of the present application, an adjusting unit is disposed in the first conversion module 3, and is used for adjusting the received current and voltage to adapt to a voltage value required by the electronic device, that is, to adapt to a current value required by the electronic device.

Further, as shown in the structure in the DC TO DC area of the first conversion module 3 shown in fig. 3, the adjusting unit in this embodiment is a pi-type circuit 7 disposed in the power supply circuit in the first conversion module 3, where the pi-type circuit 7 is at least configured TO store the excess amount of electricity when the voltage of the received direct current is higher than the voltage required by the device TO be powered, and further adjust the current delivered TO the device TO be powered TO meet the voltage requirement required by the device TO be powered.

Specifically, the pi circuit 7 has an input capacitor for storing excess power, and after the power supply device receives the dc current, a part of the dc current is regulated by the pi circuit 7 and directly supplied to the electronic device, so that after the part of the dc current is supplied to the electronic device, the operating voltage of the electronic device is not greater than the rated operating voltage thereof, or the operating power of the electronic device is not greater than the rated power thereof. And another part of the direct current, namely the direct current exceeding the current requirement of the electronic equipment, is stored in the input capacitor by the pi-type circuit 7 to be used as a supplement or spare power. For example, taking an electronic device as a notebook computer as an example, when a user uses the electronic device to work, the operating power of the electronic device is low, and when excessive current does not need to be delivered, a part of the current can be stored through the input capacitor, so that the current input into the electronic device meets the user requirement. If the user uses the electronic device to play the network game, the operating power of the electronic device is greatly increased, and the electronic device consumes more current, so that the power supply device releases part or all of the electric quantity in the input capacitor, and the electric quantity is supplied to the electronic device for use.

In order to better achieve the above technical effect, the pi circuit 7 in the embodiment of the present application may be connected in series with a switch circuit, and the switch circuit is configured to be triggered to be turned on when the current power of the device to be powered reaches a preset value, so as to allow the electric quantity stored in the pi circuit 7 to be transmitted to the second connection terminal 2.

For example, the switching circuit may detect the power of the electronic device in real time, and the specific switching circuit may be electrically connected to the electronic device controller, such as a cpu, and the switching circuit may detect the power of the electronic device through the controller, and when the power of the electronic device does not reach a preset value, the switching circuit is in an off state, the input capacitor only stores electric quantity but does not output electric quantity, and when the power of the electronic device reaches the preset value, the switching circuit is turned on, and at this time, the electric quantity stored in the input capacitor is output to the electronic device for the electronic device to use. Continuing to combine with the above embodiment as an example, when the user uses the electronic device to play a game, the power of the electronic device is large at this time, and a large amount of power needs to be consumed, and when the switch circuit detects that the current power of the electronic device reaches the preset value through, for example, the cpu, the switch circuit is switched from the off state to the on state, so that the power stored in the capacitor can be transmitted to the electronic device.

Further, the power supply device in the embodiment of the present application, when performing the step of processing the obtained alternating current into the current form usable by the device to be powered and transmitting the processed alternating current into the second connection terminal 2, specifically:

the ac power obtained is processed into dc power and fed to the second connection 2.

That is, the alternating current is converted into the direct current which can be directly used by the electronic device, and then is transmitted to the second connection terminal 2 to be input into the electronic device through the second connection terminal 2.

For specific applications, as shown in fig. 3, in the AC TO DC region, a conversion circuit may be disposed in the second conversion module 4 for converting AC power into DC power. This technical effect can be achieved, for example, by providing a rectifier.

Further, the power supply device in the embodiment of the present application further includes a housing 6, the first conversion module 3 and the second conversion module 4 are both disposed in the housing 6, and the first connection end 1 and the second connection end 2 both extend out of the housing 6. Through setting up this casing 6, can make power supply unit portable, bring the convenience for user's use.

Preferably, since the first conversion module 3 and the second conversion module 4 generally have a high voltage value due to a large amount of current, in order to avoid the first power supply and the second power supply generating static electricity, and forming a capacitor between the first power supply and the housing 6, and generating electromagnetic interference, conductive foam for absorbing static electricity to reduce electromagnetic interference is further disposed inside the housing 6 in the embodiment of the present application. The conductive foam can be arranged only in the shell 6 corresponding to the first power supply device and the second power supply device, or can be arranged on the whole inner surface, and is not unique.

The embodiment of the application also provides an electronic device which is suitable for the power supply device. The electronic equipment in the embodiment of the application is provided with the power supply device, so that the function of converting alternating current into direct current can be realized, and the transformation of the direct current can be realized simultaneously, so that the accessed direct current can be directly supplied to the equipment through voltage regulation, a user is not required to adopt two independent power supply devices to complete power supply, and convenience is provided for the user to use the electronic equipment in different occasions. It can be clearly understood by those skilled in the art that, for convenience and brevity of description, the electronic device to which the data processing method described above is applied may refer to the corresponding description in the foregoing product embodiments, and details are not repeated herein.

The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
