[0024] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] An embodiment of the present disclosure provides an electronic device. Figure 1 and Figure 2 The electronic device includes a charging device 2 and an electric device 1. The charging device 2 includes a first controller 25, a first battery 24, and a charging output contact 28; the first controller 25 and the charging output contact 28 are both connected to the first battery 24; the electric device 1 includes a second battery 17, a charging input contact 15, and an electronic device 11; the charging input contact 15 and the electronic device 11 are both electrically connected to the second battery 17; the charging output contact 28 and the charging input contact 15 can be in contact and conductive; the charging device 2 or the electric device 1 also includes a signal source 3; the signal source 3 is electrically connected to the first controller 25 and is used to output a first control signal to the first controller 25; the first controller 25 is used to control the first battery 24 to charge the second battery 17 through the contacting charging output contact 28 and charging input contact 15 according to the first control signal.

[0026] In this embodiment, the signal source 3 and the first controller 25 work together to enable the charging device 2 to controllably charge the power device 1, ensuring safe charging. The charging device 2 and the power device 1 utilize contact points, allowing the charging device 2 to directly charge the power device 1. This eliminates the need for a charging cable, simplifying the structure of the electronic device and further resolving the complex overall structure of existing chargers, charging cables, and flashlights.

[0027] In addition, when the charging output contact 28 is in contact with the charging input contact 15, the charging device 2 does not charge the electrical device because the first controller 25 does not receive the first control signal output by the signal source 3; this allows the charging device 2 and the electrical device 1 to be briefly connected, so as to facilitate carrying the charging device 2 and the electrical device 1 as a whole; in addition, it also avoids the charging device 2 from accidentally charging the electrical device 1.

[0028] The signal source 3 may be an electronic component or device capable of outputting a first control signal. The signal source 3 has a power supply inside, so that the signal source 3 can send a first control signal; of course, the signal source 3 may also be electrically connected to the first battery 24 or the second battery 17. In some examples, the charging device 2 further includes a signal source 3; the power-consuming device 1 may provide a first control signal to the first controller 25. In other examples, the power-consuming device 1 further includes a signal source 3; the charging device 2 itself may provide a first control signal to the first controller 25. The first control signal may be an electrical signal, an optical signal, or the like. For example, the electrical signal may be a high level (i.e., a high voltage), or another example may be a low level (i.e., a low voltage).

[0029] The first controller 25 can be a central processing unit (CPU), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0030] The electronic device 11 may be a component that can use electricity, such as a lamp, a display screen, an alarm, etc.

[0031] The charging output contacts 28 are made of a conductive material, which can be a metal. For example, the metal can be a single substance, such as gold, silver, iron, or copper. Alternatively, the metal can be an alloy of the above substances, such as a copper alloy. The charging input contacts 15 are made of a conductive material, which can be a metal. For example, the metal can be a single substance, such as gold, silver, iron, or copper. Alternatively, the metal can be an alloy of the above substances, such as a copper alloy. In some examples, the charging output contacts 28 and the charging input contacts 15 are made of the same material, such as a copper alloy. In some examples, both the charging output contacts 28 and the charging input contacts 15 can be conductive posts, which can be used to establish contact and communication between the charging output contacts 28 and the charging input contacts 15.

[0032] When the charging output contact 28 and the charging input contact 15 are in contact and conductive, and the first controller 25 receives the first control signal, the first controller 25 controls the first battery 24 so that the first battery 24 charges the second battery 17 through the charging output contact 28 and the charging input contact 15 .

[0033] In some examples, the first battery 24 may include a first sub-battery and a switch; the first sub-battery, the switch, and the charging output contacts 28 are electrically connected in sequence, and the first controller 25 is electrically connected to both the first sub-battery and the switch; the first controller 25 controls the switch to turn on or off. The switch may be an electromagnetic switch, for example. For example, the first battery 24 may also include a transformer electrically connected between the first sub-battery and the charging output contacts 28, and the first controller 25 controls the transformer to adjust the voltage of the first sub-battery to the voltage required by the electrical device 1. In other examples, the first battery 24 may include a first sub-battery and a voltage converter; the first sub-battery, the voltage converter, and the charging output contacts 28 are electrically connected in sequence. The first controller 25 is electrically connected to the voltage converter, which performs at least the same functions as the switch and transformer described above. The switch, transformer, and voltage converter are all conventionally known and will not be described in detail.

[0034] The first sub-battery can be a power battery, which is a power source that provides power for tools. Power batteries generally refer to batteries that power vehicles such as electric cars, electric trains, electric bicycles, golf carts, and aerospace vehicles. Of course, the first sub-battery can also be an energy storage battery, which refers to batteries used to store energy from renewable energy sources such as hydropower, thermal power, wind power, and solar power plants. The first sub-battery can also be a secondary battery, which refers to a battery that can be recharged to activate its active materials after discharge for continued use. Batteries may include, but are not limited to, lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, and lead-acid batteries.

[0035] The second battery 17 can be a power battery. A power battery is a power source that provides a power source for tools. Power batteries mostly refer to batteries that provide power for vehicles such as electric cars, electric trains, electric bicycles, golf carts, and aerospace. Of course, the second battery 17 can also be an energy storage battery. An energy storage battery refers to a battery used to store energy from renewable energy sources such as hydropower, thermal power, wind power, and solar power stations. The second battery 17 can be a secondary battery. A secondary battery refers to a battery that can be recharged to activate the active material after the battery is discharged and continue to be used. The second battery 17 can include but is not limited to lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc.

[0036] In some examples, the charging device 2 may further include a first signal indicator, which is electrically connected to the first controller 25 and the first battery 24, respectively, and is configured to indicate the charge level of the first battery 24. For example, the first signal indicator may be a traffic light, where a green light indicates that the charge level is greater than 20%, and a red light indicates that the charge level is less than 20%.

[0037] In some examples, the electrical device 1 may further include a second signal indicator electrically connected to the second battery 17. The second signal indicator indicates when the second battery 17 is charging. The second signal indicator may be a green light that illuminates when the second battery 17 is charging. For example, the second signal indicator may also be electrically connected to the second controller 32 described below. The electrical device 1 may further include a power button electrically connected to the electronic device 11 and used to control whether the electronic device 11 is enabled or disabled.

[0038] The charging output contact 28 and the charging input contact 15 may each include a positive contact and a negative contact. When the charging output contact 28 and the charging input contact 15 are in contact, the positive contact of the charging output contact 28 contacts the positive contact of the charging input contact 15, and the negative contact of the charging output contact 28 contacts the negative contact of the charging input contact 15.

[0039] In some embodiments, charging device 2 is a power bank, and power-consuming device 1 is a flashlight. In this case, electronic device 11 can be the flashlight's lamp. Of course, charging device 2 can also be an energy storage power source, an emergency power source, a vehicle power source, etc. Power-consuming device 1 can be a laptop computer, a mobile phone, etc.

[0040] In some embodiments, the charging device 2 further includes a first housing 22 and a first magnetic member 23. The first controller 25, first battery 24, first magnetic member 23, and charging output contacts 28 are disposed in the first housing 22. The charging device 2 further includes a second housing 12 and a second magnetic member 14. The second battery 17, charging input contacts 15, second magnetic member 14, and electronic device 11 are all disposed in the second housing 12. The first magnetic member 23 and the second magnetic member 14 have opposite magnetic properties. The first magnetic member 23 and the second magnetic member 14 are attracted to each other, causing the charging output contacts 28 to contact the charging input contacts 15.

[0041] The first magnetic member 23 may be a magnet, an electromagnet, etc. The second magnetic member 14 may be a magnet, an electromagnet, etc. For example, both the first magnetic member 23 and the second magnetic member 14 may be magnets.

[0042] The material of the first housing 22 can be a non-magnetic material. The material of the second housing 12 can also be a non-magnetic material. For example, the non-magnetic material can be plastic. Of course, both the first housing 22 and the second housing 12 can be made of magnetic materials. In this case, the surfaces of the first housing 22 and the second housing 12 can be treated with a non-magnetic material to render them non-magnetic. For example, a non-magnetic film can be applied.

[0043] In some examples, the first controller 25 and the first battery 24 can be disposed within the first housing 22 . The charging output contacts 28 and the first magnetic member 23 can be disposed on an outer surface of the first housing 22 .

[0044] In some examples, the second battery 17 can be disposed in the second housing 12 ; the charging input contacts 15 , the second magnetic member 14 , and the electronic device 11 are all disposed on the outer surface of the second housing 12 . Of course, the electronic device 11 can be disposed in the second housing 12 .

[0045] In some examples, the first magnetic member 23 and the second magnetic member 14 are attracted to each other, causing the charging output contact 28 to contact the charging input contact 15 , and also causing the first signal contact 27 and the second signal contact 16 described below to contact each other.

[0046] In this embodiment, the first magnetic member 23 and the second magnetic member 14 are attracted to each other by opposite polarities, so that the charging output contact 28 and the charging input contact 15 can be brought into contact. Of course, the charging output contact 28 and the charging input contact 15 can be brought into contact by plugging.

[0047] Two embodiments of the electronic device are described below.

[0048] Example 1.

[0049] Continue to see Figure 1 and Figure 2The charging device 2 also includes a first signal contact 27; the first signal contact 27 is electrically connected to the first controller 25; the power-consuming device 1 also includes a signal source 3 and a second signal contact 16; the signal source 3 includes a second controller 32; the second battery 17 and the second signal contact 16 are both electrically connected to the second controller 32; the charging output contact 28 and the charging input contact 15, as well as the first signal contact 27 and the second signal contact 16 are in contact at the same time; the second controller 32 outputs a first control signal to the first controller 25 through the contacted first signal contact 27 and the second signal contact 16.

[0050] In some examples, the second controller 32 is capable of continuously sending the first control signal; that is, the second controller 32 is always sending the first control signal; and the first control signal is transmitted to the second signal contact 16. In other examples, the electrical device 1 further includes a signal key, which is connected to the second controller 32. By pressing the signal key, the signal key is turned on and a trigger signal is sent to the second controller 32. The second controller 32 sends the first control signal to the second signal contact 16 according to the trigger signal. When the first signal contact 27 and the second signal contact 16 are in contact and conductive, the first control signal is transmitted to the first controller 25 through the second signal contact 16 and the first signal contact 27, so that the first controller 25 receives the first control signal. For example, the first control signal sent by the second controller 32 can be an electrical signal.

[0051] The charging output contact 28 and the charging input contact 15, as well as the first signal contact 27 and the second signal contact 16, simultaneously contact each other. This means that when the charging output contact 28 and the charging input contact 15 contact each other, the first signal contact 27 and the second signal contact 16 also contact each other. In some examples, the charging output contact 28 and the first signal contact 27 are fixedly connected to form the first contact portion 21, and the charging output contact 28 and the first signal contact 27 are insulated from each other; the charging input contact 15 and the second signal contact 16 are fixedly connected to form the second contact portion 13, and the charging input contact 15 and the second signal contact 16 are insulated from each other. Therefore, when the first contact portion 21 and the second contact portion 13 contact each other, the charging output contact 28 and the charging input contact 15 contact each other, and the first signal contact 27 and the second signal contact 16 also contact each other.

[0052] The second controller 32 can be a central processing unit (CPU), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The second controller 32 is also electrically connected to the electronic device 11 to control the operation of the electronic device 11. In some examples, the second controller 32 is not connected to the charging input contact 15; in this case, the electrical device 1 also includes a charging and discharging circuit, and the charging input contact 15 is electrically connected to the second battery 17 through the charging and discharging circuit. The second controller 32 is electrically connected to the charging and discharging circuit. In other examples, see Figure 3 , the charging input contact 15 is electrically connected to the second battery 17 through the second controller 32; in this case, the second controller 32 may include an electrically connected controller body and a charge-discharge circuit. The charging input contact 15 is electrically connected to the second battery 17 through the charge-discharge circuit. The controller body can be electrically connected between the charging input contact 15 and the second battery 17, or the controller body and the charging input contact 15 are not connected. Among them, the charge-discharge circuit is a prior art, and the charge-discharge circuit is used to detect the electrical parameters of the second battery 17 during the charging or discharging process of the second battery 17. The electrical parameters may be the voltage value, current value, power value, etc. of the second battery 17.

[0053] The first signal contact 27 is made of a conductive material, which can be a metal. For example, the metal can be a single substance, such as gold, silver, iron, copper, etc.; or an alloy thereof, such as a copper alloy. The second signal contact 16 is made of a conductive material, which can be a metal. For example, the metal can be a single substance, such as gold, silver, iron, copper, etc.; or an alloy thereof, such as a copper alloy. In some examples, both the first signal contact 27 and the second signal contact 16 can be conductive posts, which can be used to establish contact and communication between the first signal contact 27 and the second signal contact 16.

[0054] In this embodiment, the first signal contact 27 and the second signal contact 16 are provided so that the first control signal of the second controller 32 can be transmitted to the first controller 25 , thereby enabling the charging device to charge the electrical device 1 .

[0055] In some embodiments, when the charging amount of the second battery 17 meets the preset requirements, the second controller 32 is also used to output a second control signal to the first control signal through the first signal contact 27 and the second signal contact 16; the first controller 25 is used to control the first battery 24 to stop charging according to the second control signal; the first control signal and the second control signal are signals with opposite phases.

[0056] For example, the first control signal may be at a high level, and the second control signal may be at a low level. For another example, the first control signal may be at a low level, and the second control signal may be at a high level.

[0057] The preset requirement can be 100% power, or 90%, etc.

[0058] In some examples, the electrical device 1 further includes a detection circuit, to which both the second controller 32 and the second battery 17 are electrically connected; the detection circuit is configured to detect the charge level of the second battery 17. When the detection circuit detects that the charge level of the second battery 17 meets a preset requirement, the detection circuit sends a detection signal to the second controller 32, which then outputs a second control signal to the first controller 25 based on the detection signal. Of course, the charge level of the second battery 17 can also be detected using other methods, which will not be described in detail.

[0059] In some examples, the first controller 25 controls the switch to be cut off according to the second control signal, so that the circuit between the first sub-battery and the charging output contact 28 is cut off, thereby stopping the charging of the electrical device 1 .

[0060] In this embodiment, the first controller 25 cooperates with the second controller 32 to enable the charging device to stop charging the electrical device 1 .

[0061] In some embodiments, the charging device 2 also includes a switch key 31, which is electrically connected to the first controller 25; when the second controller 32 stops working, the switch key 31 is turned on, and the switch key 31 is used to send a third control signal to the first controller 25; the first control signal and the third control signal are signals with the same phase; the first controller 25 is used to control the first battery 24 to charge the second battery 17 for an instantaneous period of time according to the third control signal.

[0062] The switch key 31 can be a momentary switch, for example; that is, a single press of the switch key 31 turns the switch key 31 on. The switch key 31 can also be a long-press switch, such as a long-press power button. The switch key 31 has a turn-on function; pressing the switch key 31 turns the switch key 31 on. For example, the switch key 31 can also have a turn-off function; pressing the switch key 31 again turns the switch key 31 off, preventing the switch key 31 from outputting the third control signal to the first controller 25. The switch key 31 can be electrically connected to the first battery 24 or have its own internal power supply.

[0063] The second controller 32 stops working, which means that the second battery 17 is out of power and cannot provide power to the second controller 32, causing the second controller 32 to stop working.

[0064] In some examples, the first control signal can be a high level and the third control signal can be a high level. In other examples, the first control signal can be a low level and the third control signal can be a low level. The first control signal and the third control signal can be the same, for example, the voltage value of the first control signal is equal to the voltage value of the third control signal. The first control signal and the third control signal can also be different, for example, the voltage value of the first control signal is greater than the voltage value of the third control signal.

[0065] The instantaneous duration refers to the time it takes for the second battery 17 to charge from 0 to any desired level, where the desired level is greater than 0 and less than a preset requirement. In some examples, the instantaneous duration can be greater than 0 and less than or equal to 10 seconds. For example, the instantaneous duration can be 1 second, 2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, 9 seconds, 10 seconds, etc.

[0066] In this embodiment, the cooperation between the switch key 31 and the first controller 25 can enable the charging device to charge the second battery 17 for an instantaneous period of time, so that the second battery 17 has a certain amount of power. The second battery 17 can power the second controller 32, so that the second controller 32 works, and the second controller 32 sends a first control signal; thereby enabling the charging device to charge the electrical equipment.

[0067] In some embodiments, the switch key is a long-press switch. After the switch key 31 is pressed continuously for a preset time, the switch key 31 is turned on.

[0068] The preset time may be 3s to 10s, for example, 5s. A long-press switch is a switch that is turned on only after being pressed for a preset time. For example, a long-press switch may be similar to a long-press power button, that is, a long-press switch is not a momentary switch.

[0069] In this embodiment, after the switch key 31 is continuously pressed for a preset time, the switch key 31 is turned on, thereby preventing the switch key 31 from being accidentally pressed.

[0070] In some examples, the charging device 2 further includes an indicator electrically connected to the second controller 32. When the first signal contact 27 and the second signal contact 16 make contact and the first controller 25 fails to receive the first control signal, the indicator prompts the second controller 32 to cease operation. This allows the indicator to be used to determine whether the second controller 32 is operational. The indicator may be a signal light, an alarm, or the like. Of course, if the electronic device 11 is not operating after the power-consuming device 1 is turned on, this indicates that the second battery 17 is depleted, causing the second controller 32 to cease operation.

[0071] In some embodiments, the charging device 2 further includes a pull-down resistor 26; the first control signal and the second control signal are both electrical signals; one end of the pull-down resistor 26 is electrically connected between the first signal contact 27 and the first controller 25, and the other end is grounded.

[0072] For example, after the first signal contact 27 and the second signal contact 16 are in contact and conductive, the first control signal is shunted through the first signal contact 27 and the second signal contact 16 to the first controller 25 and the pull-down resistor 26. In some examples, the resistance of the pull-down resistor 26 is much greater than the resistance of the first controller 25, for example, the ratio of the pull-down resistor's resistance to the resistance of the first controller 25 is 50-100. Thus, after the first signal contact 27 and the second signal contact 16 are in contact and conductive, the current of the first control signal passing through the pull-down resistor 26 is much less than the current passing through the first controller 25. Both the high level and the low level can be electrical signals, for example, voltage or current.

[0073] In this way, after the charging device charges the electrical device 1 until the power level does not meet the preset requirements and the first signal contact 27 and the second signal contact 16 are disconnected, the pull-down resistor 26 is connected to the first controller 25, so that the high level of the first controller 25 becomes a low level, and then the first controller 25 controls the first battery 24 to stop charging according to the low level, thereby avoiding the user from touching the charging output contact 28 and causing an electric shock accident.

[0074] Example 2.

[0075] Continue to see Figure 1 and Figure 2 The charging device 2 further includes a signal source 3 ; the signal source 3 includes a switch key 31 , which is connected to the first controller 25 ; when the switch key 31 is turned on, the switch key 31 is used to send a first control signal to the first controller 25 .

[0076] The switch key 31 can be a push button switch or a momentary switch; that is, a single press of the switch key 31 turns the switch key 31 on. The switch key 31 can also be a long-press switch, such as a long-press power button. The switch key 31 has an on-state function; pressing the switch key 31 turns the switch key 31 on. For example, the switch key 31 can also have an off-state function; pressing the switch key 31 again turns the switch key 31 off, preventing the switch key 31 from outputting the first control signal to the first controller 25.

[0077] In some embodiments, the charging device 2 also includes a first signal contact 27; the first signal contact 27 is electrically connected to the first controller 25; the electrical device 1 also includes a second controller 32 and a second signal contact 16; the second battery 17 and the second signal contact 16 are both electrically connected to the second controller 32; the charging output contact 28 and the charging input contact 15, as well as the first signal contact 27 and the second signal contact 16 are in contact at the same time; when the charging amount of the second battery 17 meets the preset requirements, the second controller 32 is used to output a second control signal to the first controller 25 through the contacted first signal contact 27 and the second signal contact 16; the first controller 25 is used to control the first battery 24 to stop charging according to the second control signal.

[0078] In this embodiment, the switch key 31 cooperates with the first controller 25 to enable the charging device 2 to charge the power-consuming device 1; the first controller 25 cooperates with the second controller 32 to stop the charging device 2 from charging the power-consuming device 1.

[0079] In this embodiment, the description of the first signal contact 27 , the second controller 32 , and the second signal contact 16 may refer to the description of the first signal contact 27 , the second controller 32 , and the second signal contact 16 in the first embodiment.
