[0041] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0042] To facilitate the understanding of the embodiments of the present application, the following points are first explained:

[0043] First, in the present application, an indication includes an explicit indication (also referred to as a direct indication) and an implicit indication (also referred to as an indirect indication). Among them, explicitly indicating information A means including the information A; implicitly indicating information A means indicating information A through the correspondence between information A and information B and directly indicating information B. The correspondence between information A and information B can be predefined, pre-stored, pre-fired, or pre-configured; or, it can also mean indicating information A through information B and a preset rule.

[0044] Second, in the present application, information C is used for the determination of information D, which includes both the case where information D is determined only based on information C and the case where information D is determined based on information C and other information. In addition, when information C is used for the determination of information D, there may also be an indirect determination case, for example, the case where information D is determined based on information E and information E is determined based on information C.

[0045] Third, in this application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the relationship between associated objects and indicates that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates an "or" relationship between the associated objects before and after, but does not exclude the case where it represents an "and" relationship between the associated objects before and after. The specific meaning can be understood in combination with the context. "At least one (item)" or similar expressions refer to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can mean: a, b, c; a and b; a and c; b and c; or a, b, and c. Where a, b, and c can be single or multiple.

[0046] Fourth, in this application, the use of prefix words such as "first" and "second" is only for the convenience of distinguishing and describing different things belonging to the same name category, and does not restrict the order, size, or quantity of things. For example, "the first XX signal" and "the second XX signal" are just different pieces of information, and there is no chronological, size, or priority relationship between them.

[0047] Fifth, in the embodiments of this application, "when", "if", and "in case" all mean that the device will perform corresponding processing under certain objective circumstances, not limited to time, and it is not required that the device must have a judgment action when implemented, nor does it mean that there are other limitations.

[0048] Sixth, in this application, words such as "example", "exemplarily", "for example", or "such as" are used to give examples, illustrations, or explanations. Any embodiment or design solution described as "example", "exemplarily", "for example", or "such as" in this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "example", "exemplarily", "for example", or "such as" is intended to present relevant concepts in a specific way.

[0049] The technical solutions provided in this application can be applied to various electronic devices and their charging cables. For example: mobile phones, tablet computers, laptop computers, etc. The charging cable can be used for charging and discharging, data transmission, etc. The embodiments of this application do not limit this.

[0050] Figure 1 is a schematic structural diagram of a charging system provided in this application. As Figure 1As shown, the charging system includes a charging interface 111 and a charging head 121, which are located on the electronic device 110 and the charging cable 120 respectively. Among them, the charging interface 111 includes a magnetic induction element 111a, whose position corresponds to the position of the magnetic element 121a of the charging head 121. The charging interface 111 also includes one or more electrical connection contacts, whose positions correspond to the positions of one or more electrical connection contacts of the charging head 121. For example, the charging interface 111 may include contacts 111b, 111c, 111d, 111e as shown in Figure 1 , and their positions correspond to the contacts 121b, 121c, 121d, 121e of the charging head 121 respectively. The charging interface 111 also includes a control circuit and a charging circuit (not shown in the figure of the control circuit and the charging circuit). Among them, the magnetic induction element 111a can also be called the first magnetic induction element, and the electrical connection contact can be simply called the contact.

[0051] When the charging interface 111 and the charging head 121 are connected, the electrical connection contacts of the charging interface 111 are in contact with the electrical connection contacts of the charging head 121, that is, they are in contact with each other. For example, after the connection is completed, as shown in Figure 1 , the contacts 111b, 111c, 111d, 111e of the charging interface 111 are in contact with the contacts 121b, 121c, 121d, 121e of the charging head 121 respectively. Among them, the magnetic element 121a can be a magnet.

[0052] The charging interface 111 is normally open, that is, the internal circuit of the electronic device 110 is disconnected from the contact points 111b, 111c, 111d, and 111e when not powered on. When the magnetic induction element 111a does not sense a change in the magnetic field, the electrical connection between the charging head 121 and the electronic device 110 is disconnected. When the magnetic induction element 111a senses a change in the magnetic field, that is, when the magnetic induction element 111a senses the magnetic element 121a, the magnetic induction element 111a generates an indication signal. After the control circuit of the electronic device 110 obtains this indication signal, it closes the electrical connection between the electrical connection contacts of the charging interface 111, realizing the electrical connection between the electronic device 110 and the charging cable 120. As an example, when the electronic device 110 is electrically connected to the charging cable 120, the contact points 111b, 111c, 111d, and 111e of the charging interface 111 can be respectively connected to the pins or connection points of the Universal Serial Bus (USB) interface of the internal circuit of the electronic device 110. For example, the contact points 111b to 111e can be respectively connected to the power supply (VBUS) pin, negative data line (DM) pin, negative data line (DP) pin, and ground (GND) pin of the USB interface. The control circuit controls the charging circuit of the electronic device 110 according to this indication signal to charge the electronic device 110.

[0053] Through the above technical solution, by detecting the charging head with a magnetic induction element, it is possible to avoid short - circuit faults in scenarios such as when the charging interface of an electronic device gets water, which can further improve the life of the interface and enhance safety. By keeping the internal circuit of the electronic device and the contacts normally open, the circuit interface can be prevented from being exposed for a long time, reducing the safety hazards of using the electronic device.

[0054] Further, after obtaining the indication signal from the magnetic induction element, the control circuit can control the electronic device to discharge.

[0055] As an example, the magnetic induction element is connected to the control circuit. After obtaining the indication signal, the control circuit controls the electronic device to discharge externally, outputting a voltage of 1.8 volts (V).

[0056] Among them, optionally, the control circuit includes a control chip and a power management module. The control chip is used to receive the indication signal. When the control chip receives the indication signal, it controls the power management module to turn on the charging circuit to charge or discharge the electronic device.

[0057] Further, the charging circuit includes a VBUS pin. The power management module charges or discharges the electronic device through the VBUS pin.

[0058] Optionally, the magnetic induction element is located inside the electronic device.

[0059] In this way, the magnetic induction element can be prevented from being exposed, reducing the possibility of damage to the magnetic induction element and prolonging the service life of the magnetic induction element.

[0060] Optionally, the magnetic induction element can be a Hall sensor.

[0061] Optionally, the indication signal generated by the magnetic induction element is an electrical signal, and the magnetic induction element is located in the port detection circuit.

[0062] Figure 2 is a schematic diagram of a charging head induction circuit provided by an embodiment of the present application. As Figure 2 shown, the port induction circuit 200 includes a capacitor C1, a capacitor C2, a resistor R1, and a Hall sensor 210, and also includes a port Vcc and a port Out. When a magnetic field change is sensed, the Hall sensor 210 generates an electrical signal, which is output to the Out port through the Out pin to indicate that the electronic device closes the contacts of the internal circuit and the charging interface.

[0063] Figure 2 The Hall sensor and circuit structure shown in are only exemplary, and other types of Hall sensors and circuits including the Hall sensor can also be used to implement the above similar functions. For example, a circuit including a digital Hall sensor can be used, which is not limited. The port induction circuit can be located in the control circuit or connected to the control circuit.

[0064] Through the above technical solutions, using a Hall sensor as the magnetic induction element for charging head detection has high accuracy and sensitivity, low cost, low energy consumption, a simple circuit structure, and high reliability.

[0065] Optionally, the charging interface includes an adsorption part, which is used for adsorption connection with the magnetic element on the charging head. The adsorption part includes a magnetic material or a ferromagnetic material, or includes a magnetic material and a ferromagnetic material.

[0066] For example, the outer frame near the magnetic induction element can include a magnet, which serves as the adsorption part for adsorption connection with the magnetic element on the charging head. Another example is that the outer frame near the magnetic induction element can be a ferromagnetic material, which serves as the adsorption part. In the case where there are multiple magnetic elements on the charging head, the outer frame at the corresponding positions of the multiple magnetic elements can also include a magnet and a ferromagnetic material at the same time to adsorb the charging head.

[0067] Through the above technical solutions, the charging system replaces the plug-in connection with a magnetic adsorption connection, which can avoid the plugging and unplugging of the interface, improve the service life of the interface, and reduce problems such as loosening and damage of the interface caused by long-term use.

[0068] Optionally, the charging head includes multiple magnetic elements.

[0069] Through multiple magnetic components, the charger head and the electronic device can be adsorbed at multiple points, and the total adsorption force can be increased, improving the stability of the connection between the charger head and the charging interface.

[0070] Furthermore, two magnetic components are provided on the charger head, and the two magnetic components are respectively located at both ends of the charger head.

[0071] Figure 3 It is a charging system provided by an embodiment of the present application. Similarly to the above embodiment, the charging system includes a charging interface 310 and a charger head 320. The charging interface 310 includes a magnetic induction component 311 and multiple contacts 312, and the charger head 320 includes a magnetic component 321, a magnetic component 323, and multiple contacts 322. In addition, the size of the charger head 320 in the first direction is greater than the size in the second direction. For example, the size in the x direction is greater than the size in the y direction, and the size in the y direction is smaller than the thickness of the electronic device near the charging interface. The charger head 320 includes two magnetic components, and the two magnetic components are respectively located at both ends of the multiple contacts in the first direction. The magnetic component 321 and the magnetic component 323 may also be respectively referred to as the first magnetic component and the second magnetic component.

[0072] When the charger head 320 is connected to the charging interface 310, since the charger head 320 has two magnetic components and the adsorption force is strong, the connection of the charging system is easier. At the same time, the two magnetic components respectively located at both ends in the first direction can increase the connection stability and reduce the probability of the charger head 320 detaching from the charging interface 310.

[0073] Furthermore, the charger head includes a first magnetic component and a second magnetic component, and the magnetic poles of the first magnetic component and the second magnetic component on the side facing the charging interface are different.

[0074] For example, in Figure 3 the shown charger head 320, the magnetic component 321 may also be referred to as the first magnetic component, and the magnetic component 323 may also be referred to as the second magnetic component. The south pole (S pole) of the first magnetic component, the north pole (N pole) of the second magnetic component, and the multiple contacts 322 are located on the same side.

[0075] When the charger head 320 and the charging interface 310 are correctly connected, all the corresponding contacts of the charger head 320 and the charging interface 310 are in abutting connection. The magnetic component 321, which is the first magnetic component, is adsorbed at a position near the magnetic induction component 311 of the electronic device or the charging interface 310. At this time, the magnetic induction component 311 senses the magnetic field near the S pole of the magnetic component 321, and then the magnetic induction component 311 generates an indication signal to realize the electrical connection between the charging interface 310 and the charger head 320.

[0076] When the charger 320 and the charging interface 310 are incorrectly connected, the contacts of the charger 320 and the charging interface 310 do not all correspond and abut against each other. For example, when Figure 3 the charger 320 in [reference] is connected in reverse left and right, the magnetic element 323 is adsorbed on the electronic device or the charging interface 310, and the adsorption position is close to the magnetic induction element 311. Then, the magnetic induction element 311 senses the magnetic field near the N pole of the magnetic element 323, and the magnetic induction element 311 does not generate an indication signal. At this time, the charging interface 310 and the charger 320 are not electrically connected and cannot achieve electrical connection.

[0077] Through the technical solution provided by the embodiments of the present application, the charging interface can identify the connection state of the charger to prevent incorrect connection of the interface.

[0078] Optionally, the charger includes a first magnetic element and a second magnetic element, and the adsorption part of the charging interface includes a third magnetic element. The pointing directions of the S poles or N poles of the first magnetic element and the second magnetic element are opposite.

[0079] When the charger and the charging interface are correctly connected, the third magnetic element and the first magnetic element are adsorbed, or when the charger and the charging interface are correctly connected, the second magnetic element and the first magnetic element are adsorbed. This third magnetic element can also be referred to as the device-side magnetic element.

[0080] Figure 4 is a charging system provided by the embodiments of the present application. As Figure 4 shown, the charging system includes a charging interface 410 and a charger 420. The charging interface 410 includes a magnetic induction element 411, a plurality of contacts 412, and a device-side magnetic element 413. The charger 420 includes a first magnetic element 421, a plurality of contacts 422, and a second magnetic element 423. The pointing directions of the S poles or N poles of the first magnetic element 421 and the second magnetic element 423 are opposite. When the charger 420 and the charging interface 410 are adsorbed and connected, the first magnetic element 421 is adsorbed through the S pole, and the second magnetic element 423 is adsorbed through the N pole. The S pole of the device-side magnetic element 413 points outward from the electronic device and is used to adsorb to the N pole of the second magnetic element 423. Figure 4 The setting of the magnetic polarities of the magnetic elements in [reference] is only an example, and the present application does not limit the combination and specific methods of the magnetic polarity settings in the charging system.

[0081] When the charger 420 and the charging interface 410 are correctly connected, that is, when the first magnetic element 421 is adsorbed near the magnetic induction element 411 and the second magnetic element 423 is adsorbed and connected to the device-side magnetic element 413, the connection method can refer to the above embodiments, for example, the connection method of the charger 320 and the charging interface 310 can be referred to.

[0082] When the charging head 420 and the charging interface 410 are not correctly connected, for example, when the first magnetic element 421 of the charging head 420 approaches the device-end magnetic element 413 of the charging interface 410, since repulsive force is generated between like magnetic poles, the charging head 420 and the charging interface 410 cannot be magnetically adsorbed and connected.

[0083] Through the technical solution provided by the embodiments of the present application, through the combination of magnetic elements, an additional detection of the interface can be added, and it is easy to identify whether the interface is correctly connected, and it can quickly indicate to the user whether the connection is successful, and the implementation cost is relatively low.

[0084] Optionally, in the case where the charging head includes multiple magnetic elements, the adsorption part of the charging interface includes multiple magnetic induction elements.

[0085] For example, Figure 4 411 in can be the first magnetic induction element, and 413 can also be the second magnetic induction element. The first magnetic induction element and the second magnetic induction element are also respectively located at both ends of the charging interface. The S poles or N poles of the first magnetic element 421 and the second magnetic element 423 point in opposite directions. When the first magnetic induction element 411 and the second magnetic induction element 413 respectively detect the magnetic fields generated by the corresponding magnetic poles of the first magnetic element 421 and the second magnetic element 423, that is, when the first magnetic induction element 411 and the second magnetic induction element 413 respectively detect the first magnetic element 421 and the second magnetic element 423, the first magnetic induction element 411 and the second magnetic induction element 413 respectively generate a first indication signal and a second indication signal; the control circuit receives the first indication signal and the second indication signal, and controls the charging circuit to charge the electronic device; when the first magnetic induction element 411 does not detect the magnetic field generated by the corresponding magnetic pole of the first magnetic element 421, or the second magnetic induction element 413 does not detect the magnetic field generated by the corresponding magnetic pole of the second magnetic element 423, the control circuit does not indicate the electronic device to charge. The first indication signal, the second indication signal, etc. can be collectively referred to as indication signals.

[0086] Through the technical solution provided by the embodiments of the present application, through multiple magnetic elements and multiple magnetic induction elements, it is possible to identify whether the interface is correctly connected.

[0087] Optionally, the charging interface further includes an interface detection element, and the interface detection element is used to detect and identify the charging head. When the interface detection element detects that the connected charging head is a permitted interface, the interface detection element generates an identification signal.

[0088] For example, Figure 4The 413 therein can be an interface detection component, and the 423 can be an interface chip. When the charger 420 is connected to the charging interface 410, the interface detection component 413 detects the interface chip 423 to determine whether the charger 420 is a permitted charger. When it is determined that the charger 420 is a permitted charger, the interface detection component 413 generates an identification signal. When the indication signal and the identification signal are obtained, the control circuit closes the interface and the internal circuit, and controls the charging circuit to charge or discharge the electronic device.

[0089] Through the technical solution provided by the embodiments of the present application, the authenticity of the charger connected to the electronic device can be detected, and the connection security can be improved.

[0090] Further, the interface detection component can be connected to the control circuit. After obtaining the identification signal from the interface detection component, or, after obtaining the first indication signal from the magnetic induction component and the identification signal from the interface detection component, or, after obtaining the first indication signal from the first magnetic induction component, the second indication signal from the second magnetic induction component, and the identification signal from the interface detection component, the control circuit controls the charging circuit to charge or discharge the electronic device.

[0091] Optionally, the charging interface includes an indicator light, and when the charging system is correctly connected, the indicator light is on.

[0092] Figure 5 is a charging system provided by the embodiments of the present application. As Figure 5 shown, the charging system includes a charging interface 510 and a charger 520. The charging interface 510 includes an indicator light 511, a magnetic induction component 512, and a plurality of contacts 513. The charger 520 includes a first magnetic component 521 and a plurality of contacts 522. The indicator light 511 is connected to the control circuit of the electronic device. When the charging system is correctly connected, the control circuit receives an indication signal, and the control circuit controls the indicator light 511 to be on to indicate to the user that the charging system is normally connected; when the charging system is not connected, the control circuit does not control the indicator light 511 to be on.

[0093] Among them, when the first indication signal is obtained, or the first indication signal and the second indication signal are obtained, or the first indication signal, the second indication signal, and the identification signal are obtained, the indicator light 511 can determine that the charging system is correctly connected.

[0094] Through the technical solution provided by the embodiments of the present application, it is possible to indicate to the user whether the connection is successful.

[0095] Further, the indicator light includes two colors or two brightness levels, and the two colors indicate that the charging system is correctly connected or incorrectly connected, or the two brightness levels indicate that the charging system is correctly connected or incorrectly connected.

[0096] An example, Figure 5 The indicator light 511 in Figure 5 includes two situations: green light on and red light on, corresponding to correct connection and incorrect connection of the charging system respectively. When the charging interface 510 is connected to the charger head 520, the indicator light 511 indicates whether the connection is correct by lighting the corresponding color.

[0097] Another example, Figure 5 The indicator light 511 in Figure 5 includes two situations: high brightness and low brightness, corresponding to correct connection and incorrect connection of the charging system respectively. When the charging interface 510 is connected to the charger head 520, the indicator light 511 indicates whether the connection is correct by the corresponding brightness.

[0098] Through the technical solution provided by the embodiments of the present application, it is possible to indicate to the user whether the connection is made and whether the connection is correct, improving the convenience of use and the user experience.

[0099] The indicator light can also have other forms besides brightness and color, and more combinations of situations can be used to prompt other information for the user, which is not limited.

[0100] Optionally, multiple contacts of the charging interface are located in a groove of the outer frame of the electronic device, and the multiple contacts protrude outward from the bottom of the groove.

[0101] Figure 6 It is a cross-sectional view of a charging system provided by the embodiments of the present application and the electronic device where it is located. As Figure 6 shown, the charging interface of the charging system includes a magnetic induction element 611 and multiple contacts 613. The outer frame 615 of the electronic device has an iron part 612 near the magnetic induction element 611. The charger head includes a magnetic element 621 and multiple contacts 622. Among them, the multiple contacts 613 of the charging interface are located in the groove 614 of the outer frame 615, and the multiple contacts 622 of the charger head protrude outward from the charger head. When the electronic device is connected to the charging cable through the charging system, the magnetic element 621 is positioned and adsorbed through the iron part 612, the multiple contacts 622 of the charger head are tightened by the magnetic adsorption force, and are in contact with the multiple contacts 613 of the charging interface in the groove 614, and the charger head presses the opening of the groove 614. When the magnetic induction element 611 senses the magnetic field of the magnetic element 621 and is turned on, the electronic device and the charging cable are electrically connected.

[0102] Through the technical solution provided by the embodiments of the present application, the depth of the groove of the charging interface can be relatively low. For example, the depth of the groove can be less than or equal to 5 mm, which can make the charging interface of the electronic device more beautiful. And because the depth of the groove is relatively low, when the charger head is pulled off by a large external force, the charger head can be easily detached, so as not to damage the interface. In addition, the charger head presses the groove through the magnetic adsorption force, which can play a role in sealing and waterproofing, and can prevent the interface from short-circuiting.

[0103] Figure 7 It is a cross-sectional view of another charging system provided by an embodiment of the present application and the electronic device where it is located. The structure of the charging interface of this charging system is similar to Figure 6 the following. This charging interface includes a magnetic induction element 711 and a plurality of contacts 713. The outer frame 715 of the electronic device has an iron part 712 near the magnetic induction element 711. The charging head of this charging system includes a magnetic element 721 corresponding to the position of the iron part 712, a protrusion 723, and a plurality of contacts 722 located on the protrusion 723. When the charging interface is connected to the charging head, the protrusion 723 is embedded in the groove 714, and the plurality of contacts 722 of the charging head are in contact with the plurality of contacts 713 of the charging interface.

[0104] Through the technical solution provided by the embodiment of the present application, the charging head enters the groove through the protrusion of the charging head, which can play a role in positioning the interface connection and sealing and waterproofing between the interfaces, and can prevent short-circuit faults of the interface.

[0105] Optionally, the plurality of contacts of the charging interface protrude outward from the outer frame of the electronic device or are flush with the outer surface of the outer frame.

[0106] Figure 8 It is a cross-sectional view of another charging system provided by an embodiment of the present application and the electronic device where it is located. As Figure 8 shown, this charging interface includes a magnetic induction element 811 and a plurality of contacts 813. The outer frame 814 of the electronic device has an iron part 812 near the magnetic induction element 811. The charging head of this charging system includes a magnetic element 821 corresponding to the position of the iron part 812 and a plurality of contacts 822.

[0107] Through the technical solution provided by the embodiment of the present application, the plurality of contacts of the charging interface protrude outward from the electronic device. The height of this protrusion can be relatively low. For example, the height of the protruding contacts can be less than or equal to 1 mm; or, the plurality of contacts of the charging interface are flush with the outer surface of the outer frame of the electronic device. In this way, the appearance of the electronic device near the charging interface is relatively flat and more beautiful.

[0108] The iron part corresponding to the magnetic element of the charging head in the above embodiments can also be an integrally formed middle frame or outer frame, etc. For example, in the Figure 6 charging system shown, the outer frame 615 can be a middle frame made of iron material, and the outer frame 615 and the iron part 612 are integrally formed.
