Detailed implementation manners

[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a charger 1, including a housing 11, a knob 12, a knob detection structure 2, a main control board 131, a display 134, and a charging control unit 132.

[0028] The housing 11 is used to protect the components arranged inside the housing 11. The material of the housing 11 can be plastic or metal. Specifically, the material of the housing 11 can be plastic, so that the housing 11 is insulated, thereby reducing the risk of electric shock to users. And because the plastic material is lighter in weight, the housing 11 is lighter in weight, so that the overall weight of the charger 1 is lighter, which is convenient for users to carry and use the charger 1. Specifically, the housing 11 can be integrally injection-molded, so that the housing 11 has high structural strength, so that the housing 11 is not easily damaged, can protect other components inside the housing 11, and reduce the probability of damage to other components, so that the charger 1 can have a long service life. The housing 11 also has a mains interface (not shown in the figure), and the mains interface is used to connect to the mains.

[0029] The knob 12 is rotatably arranged on the housing 11, so that the user can operate the knob 12 to control the charger 1.

[0030] The knob detection structure 2 is arranged inside the housing 11 and is connected to the knob 12. Exemplarily, the knob detection structure 2 may include at least one of an electrically conductive mechanical structure, a magnetic detection structure, an optical detection structure, a pressure detection structure, and a toggle detection component, so that the knob detection structure 2 can obtain at least one of the rotation parameter, the pressing parameter, and the toggling parameter of the knob 12, so that the main control board 131 can control the charging control unit 132 to work according to the corresponding parameters. Specifically, the knob detection structure 2 is at least used to detect the rotation parameter of the knob 12; Exemplarily, the rotation parameter may include the rotation angle and / or the rotation direction.

[0031] The main control board 131 is arranged inside the housing 11, is electrically connected to the knob detection structure 2, and is connected to the battery. It can be understood that the knob detection structure 2 may further include a detection board, the detection board is electrically connected to the main control board 131, and the detection board is used to detect at least one of the rotation parameter, the pressing parameter, and the toggling parameter of the knob 12 and send the corresponding parameters to the main control board 131.

[0032] The display 134 is arranged on the housing 11 and is exposed from the housing 11, and the display 134 is electrically connected to the main control board 131.

[0033] The charging control unit 132 is electrically connected to the main control board 131. Exemplarily, the charging control unit 132 includes a charging circuit (not shown in the figure) and a plurality of charging ports 1321. The charging ports 1321 are arranged on the housing 11 and are exposed from the housing 11, and the plurality of charging ports 1321 are all electrically connected to the main control board 131. The user can operate the knob 12 so that the main control board 131 obtains at least one of the rotation parameter, the pressing parameter, and the toggling parameter of the knob 12 through the knob detection structure 2, so that the main control board 131 can control the display 134 to switch and display the charging information of different charging ports 1321 according to the corresponding parameters. Among them, the charging information includes at least one of the charging power, the charging voltage, and the charging current.

[0034] Exemplarily, the charging port 1321 includes at least one of a USB-A interface, a Micro USB interface, a USB Type-C interface, or a Lightning interface. The charger 1 can supply power to the charging port 1321 through the mains interface or through the battery, so that the charging port 1321 can charge an external device. The external device includes but is not limited to a mobile phone, an earphone, a tablet computer, and a smart watch.

[0035] Exemplarily, the charging circuit includes a rectifier module (not shown in the figure), a transformer module (not shown in the figure) and a protocol chip (not shown in the figure). The rectifier module is connected to the mains interface and is used to convert alternating current into direct current. The transformer module is connected to the output end of the rectifier module and the charging port 1321 to transform the output voltage of the rectifier module to adapt to the charging information of the external device, thereby improving the charging efficiency of the charger for charging the external device.

[0036] The rectifier module may include a rectifier circuit (not shown in the figure), a filter circuit (not shown in the figure) and a voltage stabilizing circuit (not shown in the figure), the rectifier circuit is used to rectify the alternating current into direct current, and the rectifier circuit includes but is not limited to a bridge rectifier circuit and a PWM (pulse width modulation) rectifier circuit. The filter circuit is used to filter the pulsating direct current output by the rectifier circuit so that the waveform of the output direct current is smooth. The voltage stabilizing circuit is used to keep the output voltage constant. In the embodiment of the present application, there is no restriction on the specific form of the rectifier module.

[0037] The transformer module is used to boost or reduce the DC power output by the rectifier module and then supply power to the charging port 1321 so that the charging port 1321 outputs the corresponding voltage. Specifically, the protocol chip can be connected to the charging port 1321 and the transformer module. After the external device is connected to the corresponding charging port 1321, the protocol chip exchanges information with the external device through the charging port 1321. The content of the information exchange includes but is not limited to the remaining power of the external device and the rated charging power of the external device. After that, the protocol chip can output the power parameter information corresponding to the external device to the transformer module, so that the transformer module can output the charging power required by the external device, thereby matching the output power of the power supply circuit with the external device. In other embodiments, the above process can be referred to as handshake communication between the charger 1 and the external device.

[0038] Exemplarily, the fast charging protocols supported by the protocol chip include at least one of the USB PD (Power Delivery) fast charging protocol, QC (Quick Charge) fast charging protocol, FCP (Fast Charge Protocol) protocol, SCP (Super Charge Protocol) protocol, and Mi Turbo Charge protocol. In other embodiments, the fast charging protocols supported by the protocol chip may also include other types, which can be selected according to the applicable scope of the product.

[0039] It can be understood that the charger 1 can also be communicatively connected to an external device with a display, so that the main control board 131 can transmit display information to the external device, thereby displaying a picture on the display of the external device, and the charger 1 can also be controlled by touching the display of the external device. Among them, the communication connection methods include at least one of wired communication, WLAN (Wireless Local Area Network), RFID (Radio Frequency Identification), NFC (Near Field Communication), ZigBee, Bluetooth, and infrared rays.

[0040] Please refer to Figure 1 and Figure 2 , in the embodiment of the present application, the user operates the knob 12, so that the knob detection structure 2 at least detects the rotation parameters of the knob 12, thereby realizing the control of the charging control unit 132 to realize the control of the charger 1. Compared with the user controlling the charger 1 to work through multiple buttons and multiple selections, the present application only needs to operate a single knob 12 to realize the control of the charger 1, which can simplify the operation steps of the user, thereby improving the convenience of use of the charger 1; it can also simplify the control logic of the charger 1, reduce the complexity of the operation procedure of the charger 1, and improve the system stability of the charger 1; moreover, since a single knob 12 can be used to realize the control of the charger 1, the number of operable parts on the charger 1 can be streamlined, so as to optimize the appearance layout of the charger 1, and it can also reduce the use of internal components of the charger 1, reduce the space occupied by the components in the housing 11, and further reduce the volume of the housing 11, so that the overall size of the charger 1 is smaller, which is convenient for the user to carry and use the charger 1.

[0041] It can be understood that the charger 1 involved in the present application is mainly suitable for powering mobile phones, earphones, tablet computers, smart watches, and other small external devices. For example, the charger 1 can be a desktop charger; it is not suitable for powering large devices such as electric vehicles and electric scooters. For example, the charger 1 cannot be a charging pile.

[0042] Please refer to Figure 1 and Figure 2 , in one embodiment, the charger 1 further includes a function module, and the function module includes at least one of an Internet of Things module, a Bluetooth module, a timing module, a power-on / off module, and a wireless network module. The main control board 131 is further configured to control the function module to work according to the rotation parameters.

[0043] Please refer to Figures 1-3, the knob detection structure 2 may include a follower 21 and a rotation detection component 22. The follower 21 is connected to the knob 12 and can rotate following the knob 12; the rotation detection component 22 is electrically connected to the main control board 131. The rotation detection component 22 cooperates with the follower 21 so that the main control board 131 obtains the rotation parameters of the knob 12. The main control board 131 can control the charging port 1321 to work according to the rotation parameters. The main control board 131 is also used to control the display 134 to switch and display the charging information of different charging ports 1321.

[0044] It can be understood that the rotation parameter can be the preset rotation position of the knob 12. When the knob 12 rotates to the first preset rotation position, the display 134 can display the charging information of the first charging port; when the knob 12 rotates to the second rotation position, the display 134 can display the charging information of the second charging port; when the knob 12 rotates to the third rotation position, the display 134 can display the charging information of the third charging port... and so on. The circumference can be evenly divided into multiple rotation position groups, and each rotation position group includes multiple rotation positions. Thus, when the knob 12 rotates, the cyclic rotation of the display information can be realized, and further the stepless adjustment of the knob 12 can be realized.

[0045] Please refer to Figures 2-4 , in an embodiment, the follower 21 may include a conductive member 211. The conductive member 211 is connected to the knob 12 to rotate following the knob 12; the rotation detection component 22 includes a first electrical connector 221, a second electrical connector 222, and a rotation detection chip (not shown in the figure). The first electrical connector 221 is connected to the conductive member 211. The second electrical connector 222 is arranged at an interval from the first electrical connector 221 and can be intermittently electrically connected to the conductive member 211 so that the second electrical connector 222 is conducted with the first electrical connector 221; the rotation detection chip is electrically connected to the main control board 131 and is used to detect the rotation angle and rotation direction of the knob 12. Combining with the conduction signal between the second electrical connector 222 and the first electrical connector 221, the main control board 131 obtains the rotation parameters of the knob 12. Exemplarily, the material of the conductive member 211 can be a metal material, such as copper and gold.

[0046] It can be understood that in order to prevent the first electrical connector 221 and the second electrical connector 222 from being conducted with the knob 12, the knob 12 can be made of an insulating material, such as plastic.

[0047] Please refer to Figure 3 and Figure 4, in the embodiment of the present application, the conductive member 211 and the knob 12 can also be connected by an insulating structure. The insulating structure includes an insulating shell 14. The insulating shell 14 is connected to the knob 12. The conductive member 211 is disposed on the insulating shell 14 and is spaced from the knob 12. The connection manner between the insulating shell 14 and the knob 12 can be but is not limited to screwing, gluing, and clamping.

[0048] Please refer to Figures 3-5 , in one embodiment, the conductive member 211 can include a conductive disk 2111 and a peripheral edge 2112. The conductive disk 2111 has an avoidance hole 2111A. The knob 12 passes through the avoidance hole 2111A and is spaced from the hole wall of the avoidance hole 2111A. The conductive disk 2111 is connected to the knob 12 through the insulating shell 14. The peripheral edge 2112 surrounds the circumferential side of the conductive disk 2111. The peripheral edge 2112 has a plurality of contact portions 2112A that are evenly spaced along the circumferential direction of the conductive disk 2111. The contact portions 2112A are used for electrically connecting with the second electrical connection member 222.

[0049] Specifically, the peripheral edge 2112 has a plurality of through grooves 2112B. The plurality of through grooves 2112B are evenly spaced along the circumferential direction of the conductive disk 2111. A contact portion 2112A is formed between two adjacent through grooves 2112B. It can be understood that the contact portion 2112A can also protrude from the surface of the peripheral edge 2112. In the embodiment of the present application, the specific form of the formation of the contact portion 2112A is not limited.

[0050] Exemplarily, please refer to Figure 3 and Figure 6 , the rotation detection assembly 22 can include a first electrical connection member 221 and two second electrical connection members 222. The first electrical connection member 221 has a contact point that contacts the conductive disk 2111. The two second electrical connection members 222 are spaced apart and are respectively disposed on both sides of the first electrical connection member 221. During the rotation of the knob 12 relative to the housing 11, only one of the two second electrical connection members 222 contacts and conducts with the contact portion 2112A, and the two second electrical connection members 222 alternately contact and conduct with one of the plurality of contact portions 2112A, so as to realize the switching of the conduction signal. By matching the rotation angle and rotation direction of the knob 12 detected by the rotation detection chip, it can correspond to the current rotation position of the knob 12, so that the main control board 131 can obtain the rotation parameters of the knob 12.

[0051] It can be understood that the rotation parameters obtained by the main control board 131 can be the electrical signals obtained by respectively receiving the conduction of the first electrical connector 221 and the second electrical connector 222 and the detection signals of the rotation detection chip. Furthermore, the main control board 131 can obtain the rotation parameters through the electrical signals and the detection signals. It can also be that the rotation detection chip receives the electrical signals of the conduction of the first electrical connector 221 and the second electrical connector 222, combines its own detection signals, and transmits them to the main control board 131 in combination, so that the main control board 131 can obtain the rotation parameters. In the embodiments of the present application, the process of the main control board 131 obtaining the rotation parameters is not specifically limited.

[0052] Please refer to Figure 1 and Figures 3-6 , it can be understood that the peripheral edge 2112 can be arranged at an angle with the conductive disk 2111. The peripheral edge 2112 and the conductive disk 2111 can jointly enclose a receiving cavity. The two second electrical connectors 222 can extend into the receiving cavity, and other structures in the rotation detection assembly 22 can also be at least partially located in the receiving cavity. Thus, the size of the rotation detection assembly 22 can be reduced in the axial direction of the knob 12, so as to reduce the space occupied by the rotation detection assembly 22 in the housing 11, thereby reducing the volume of the housing 11, making the charger 1 miniaturized, and facilitating the user to use and carry the charger 1. In the embodiments of the present application, the peripheral edge 2112 can be perpendicular to the conductive disk 2111, so that in the radial direction of the knob 12, the overall size of the knob detection structure 2 is small, thereby miniaturizing the charger 1.

[0053] It can be understood that in other embodiments, each contact portion 2112A can be made with different inclination angles or surface roughnesses. By detecting the deformation amount of the second electrical connector 222, the position where the second electrical connector 222 is located can be obtained, and thus it can also correspond to the current rotation position of the knob 12. Details are not elaborated here.

[0054] Please refer to Figure 1 , Figure 2 and Figure 7 , in yet another embodiment, the follower 21 can further include a magnetic member 212, and the magnetic member 212 is connected to the knob 12; the rotation detection assembly 22 includes a magnetic induction element 223, and the magnetic induction element 223 is electrically connected to the main control board 131. When the magnetic member 212 moves following the knob 12, it can cause a change in the magnetic field at the position where the magnetic induction element 223 is located. The magnetic induction element 223 can generate different electrical signals according to the magnetic field change, so that the main control board 131 can obtain the rotation parameters of the knob 12. In the embodiments of the present application, neither the position nor the placement manner of the magnetic induction element 223 in the magnetic field of the magnetic member 212 is specifically limited.

[0055] Exemplarily, the magnetic member 212 can be a magnet, and the magnetic induction element 223 can be a magnetic induction chip. The magnetic induction chip can output different electrical signals according to different magnetic field intensities. Specifically, when the knob 12 drives the magnet to move, the magnetic field intensity around the magnetic induction chip will change, so that the magnetic induction chip outputs different electrical signals, and further enables the main control board 131 to obtain electrical signals corresponding one-to-one to the position of the magnet, that is, the rotation parameters of the knob 12 can be obtained.

[0056] Please refer to Figure 1 、 Figure 2 and Figure 8 , in another embodiment, the driven member 21 includes a reflective member 213. The reflective member 213 is connected to the knob 12, and different positions of the reflective member 213 have different reflectivities around the axis of the knob 12; the rotation detection assembly 22 includes a light-emitting element 224 and a light-sensitive element 225. The light-emitting element 224 is electrically connected to the main control board 131; the light-sensitive element 225 is electrically connected to the main control board 131 and is used to receive the changing light signal emitted by the light-emitting element 224 and reflected by the reflective member 213, and generate different electrical signals, which can also enable the main control board 131 to obtain the rotation parameters of the knob 12. It can be understood that the reflective member 213 has at least one of the following regions: at least one of a bright and dark marking region, a region with a changing polish, a pit, and a convex region.

[0057] Exemplarily, the rotation detection assembly 22 can include a light-sensing chip, and the light-sensing chip has a light-emitting element 224 and a light-sensitive element 225, so that the light-sensing chip can receive the changing light signal emitted by the light-emitting element 224 and reflected by the reflective member 213, and generate different electrical signals, so that the main control board 131 can obtain the rotation parameters of the knob 12.

[0058] It can be understood that different regions with different reflectivities can also be formed on the surface of the knob 12 by processing, so that the light signals received by the light-sensitive element 225 are different, so that the light-sensitive element 225 outputs different electrical signals, so that the main control board 131 can obtain the corresponding electrical signals, that is, the rotation parameters of the knob 12 can be obtained.

[0059] Please refer to Figures 1-3 and Figure 9 , in one embodiment, the knob detection structure 2 further includes a pressing detection assembly 23. The pressing detection assembly 23 is electrically connected to the main control board 131. When the knob 12 is pressed along its own axis, the pressing detection assembly 23 can generate corresponding pressing parameters; wherein, the main control board 131 controls the charging control unit 132 to work according to the pressing parameters, and the pressing parameters include at least one of a long-press parameter and a short-press parameter. The main control board 131 can also control the display 134 to display the charging information of the charging control unit 132 according to the pressing parameters.

[0060] Please refer to Figures 1-3 Specifically, the press detection component 23 may include a third electrical connector 231, a fourth electrical connector 232 and a conductive spring 233. The third electrical connector 231 is electrically connected to the main control board 131; the fourth electrical connector 232 is electrically connected to the main control board 131, and is spaced apart from the third electrical connector 231; the conductive spring 233 can be squeezed and deformed by the knob 12 to conduct the electrical connection between the third electrical connector 231 and the fourth electrical connector 232, so that the main control board 131 obtains the press parameter of the knob 12, so that the main control board 131 can control the charging control unit 132 to work according to the press parameter, and the main control board 131 can also control the display 134 to display the charging information of the charging control unit 132 according to the press parameter.

[0061] Please refer to Figures 1-3 and Figure 9 For example, the middle part of the conductive spring 233 can be deformed by the compression of the knob 12, the contact of the third electrical connector 231 can keep in contact with the peripheral side of the conductive spring 233, and the contact of the fourth electrical connector 232 is arranged corresponding to the middle part of the conductive spring 233, so that when the knob 12 is pressed, the conductive spring 233 can be deformed in the direction close to the fourth electrical connector 232 until the conductive spring 233 contacts the fourth electrical connector 232, so that the third electrical connector 231 and the fourth point connector 232 are connected through the conductive spring 233, and then the main control board 131 obtains the pressing parameter of the knob 12. The main control board 131 can determine the long press parameter and the short press parameter according to the length of time the third electrical connector 231 and the fourth point connector 232 are connected.

[0062] Furthermore, the third electrical connector 231 may have a plurality of contact points contacting the conductive spring sheet 233 to reduce the probability of disconnection between the third electrical connector 231 and the conductive spring sheet 233 , thereby improving the stability of the main control board 131 in acquiring the pressing parameters.

[0063] Please refer to Figure 1 , Figure 2 and Figure 7 It can be understood that when the follower 21 includes the magnetic part 212 and the rotation detection component 22 includes the magnetic sensing element 223, pressing the button along the axis of the knob 12 can also cause the magnetic field at the location of the magnetic sensing element 223 to change. The magnetic sensing element 223 can generate different electrical signals according to the change in the magnetic field, so that the main control board 131 obtains the pressing parameters of the knob 12.

[0064] Please refer to Figure 1 , Figure 2 and Figure 8It can be understood that when the follower 21 includes the reflector 213; the rotation detection component 22 includes the light-emitting element 224 and the photosensitive element 225, pressing the button along the axis of the knob 12 can also enable the photosensitive element 225 to receive the changing light signal emitted by the light-emitting element 224 and reflected by the reflector 213, and generate different electrical signals, and also enable the main control board 131 to obtain the pressing parameters of the knob 12.

[0065] Please refer to Figure 1 , Figure 2 and Figure 7 It can be understood that in order to facilitate button resetting, the charger 1 can also include an elastic member, one end of the elastic member is connected to the knob 12, and the other end of the elastic member is connected to the shell 11, so that when the user presses the knob 12, the elastic member is deformed so that the press detection component 23 can detect the press parameter. When the user does not press the knob 12, the elastic force of the elastic member pushes the knob 12 to reset, so that the user can press the knob 12 next time.

[0066] It can be understood that the knob detection structure 2 can also include a toggle detection component (not shown in the figure), which is electrically connected to the main control board 131. When the knob 12 is toggled along a direction deviating from its own axis, the toggle detection component can generate corresponding toggle parameters; wherein the main control board 131 controls the charging control unit 132 to operate according to the toggle parameters, and the main control board 131 can also control the display 134 to display the charging information of the charging control unit 132 according to the pressing parameters.

[0067] Exemplarily, the knob detection structure 2 may also include a spherical shell, a sphere and a lever. The sphere is rotatably arranged in the spherical shell. The spherical shell has an opening. One end of the lever is connected to the sphere. The other end of the lever is passed through the opening and connected to the knob 12. The lever detection component may include at least one of a magnetic detection structure and an optical detection structure.

[0068] Exemplarily, the toggle detection component may include a magnetic component and a magnetic sensing element. The magnetic component is disposed on the sphere, and the magnetic sensing element is disposed on the sphere shell and is electrically connected to the main control board 131. When the magnetic component moves with the sphere, it can cause a change in the magnetic field at the location of the magnetic sensing element. The magnetic sensing element can generate different electrical signals according to the change in the magnetic field, so that the main control board 131 can obtain the toggle parameters of the knob 12. In the embodiment of the present application, there is no specific limitation on the position and placement of the magnetic sensing element in the magnetic field of the magnetic component.

[0069] Exemplarily, the dial detection component may include a reflective member, a light-emitting element, and a photosensitive element. The reflective member is disposed on the surface of the sphere, and the light-emitting element and the photosensitive element are disposed on the inner wall of the spherical shell and are electrically connected to the main control board 131 respectively. The photosensitive element can receive the changing optical signal emitted by the light-emitting element and reflected by the reflective member, and generate different electrical signals, so that the main control board 131 can obtain the dialing parameters of the knob 12.

[0070] It can be understood that different regions with different light reflectance can also be formed on the surface of the sphere, so that the optical signals received by the photosensitive element are different, so that the photosensitive element outputs different electrical signals, so that the main control board 131 can obtain the corresponding electrical signals, that is, the dialing parameters of the knob 12 can be obtained.

[0071] Please refer to Figure 1 、 Figure 2 and Figure 10 , the embodiment of the present application also provides a control method for the charger 1. The control method includes:

[0072] Step S100: Obtain the rotation parameters of the knob 12 detected by the knob detection structure 2, where the rotation parameters include the rotation angle and / or the rotation direction.

[0073] In the embodiment of the present application, the user rotates the knob 12 to drive the driven member 21 to rotate, and the rotation detection component 22 cooperates with the driven member 21 so that the main control board 131 obtains the rotation parameters of the knob 12.

[0074] Step S200: Control the charging control unit 132 to work at least according to the rotation parameters.

[0075] In the embodiment of the present application, the main control board 131 can control the opening and closing of the charging control unit 132 according to the rotation parameters, and can also enter the editing mode of the charging information of the charging port 1321 according to the rotation parameters to edit the charging information of the charging port 1321.

[0076] Step S300: Control the display 134 to display the charging information of the charging control unit 132.

[0077] In the embodiment of the present application, the main control board 131 can control the display 134 to display the opening and closing information of the charging control unit 132 according to the rotation parameters, or can control the display 134 to display the charging information of the charging control unit 132.

[0078] It can be understood that in other embodiments, the main control board 131 can control the display to display the charging information of the charging control unit 134 only through the rotation parameters. The main control board 131 can also control the charging control unit 134 to work only through the rotation parameters.

[0079] Please refer toFigures 1-8 and Figure 11 , in one embodiment, step S200 includes:

[0080] Step S210, enter the display mode of the charging information of the charging port 1321 according to the rotation parameter.

[0081] In the embodiment of the present application, by rotating the knob 12, the main control board 131 can obtain the corresponding rotation parameter, so that the main control board 131 enters the display mode of the charging information of the charging port 1321 according to the obtained rotation parameter.

[0082] Step S300 includes:

[0083] Step S310, control the display 134 to switch and display the charging information of different charging ports 1321 according to the rotation parameter; the charging information includes at least one of charging power, charging voltage, and charging current.

[0084] In the embodiment of the present application, when the charger 1 is in the display mode of the charging information of the charging port 1321, rotate the knob 12. The knob 12 can drive the driven member 21 to rotate, so that the main control board 131 can obtain the rotation parameter of the knob 12 via the rotation detection component 22, and then the main control board 131 can control the display 134 to switch and display the charging information of the charging port 1321 according to the rotation parameter.

[0085] Specifically, the knob detection structure 2 can be an electrically conductive mechanical structure. For example, the driven member 21 includes a conductive member 211, and the rotation detection component 22 includes a first electrical connector 221, a second electrical connector 222, and a rotation detection chip. When the user rotates the knob 12, the knob 12 drives the conductive member 211 to rotate, so that only one of the two second electrical connectors 222 is in contact conduction with the contact portion 2112A, and the two second electrical connectors 222 alternately contact and conduct with one of the multiple contact portions 2112A, thereby realizing the switching of the conduction signal. Combining the rotation angle and rotation direction of the knob 12 detected by the rotation detection chip, it can correspond to the current rotation position of the knob 12, that is, the rotation parameter of the knob 12 obtained by the main control board 131.

[0086] In other embodiments, the knob detection structure 2 can also detect the rotation position of the knob 12 through a magnetic detection structure and an optical detection structure, and can also enable the main control board 131 to obtain the rotation parameter of the knob 12, which will not be elaborated here.

[0087] It can be understood that the rotation parameter can be the preset rotation position of the knob 12. When the knob 12 rotates to the first preset rotation position, the display 134 can display the charging information of the first charging port; when the knob 12 rotates to the second rotation position, the display 134 can display the charging information of the second charging port; when the knob 12 rotates to the third rotation position, the display 134 can display the charging information of the third charging port... and so on. The circumference can be divided into multiple rotation position groups, and each rotation position group includes multiple rotation positions. Thus, when the knob 12 rotates, the cyclic rotation of the displayed information can be realized, and further the stepless adjustment of the knob 12 can be realized.

[0088] Please refer to Figures 1-3 、 Figure 9 and Figure 12 , in one embodiment, step S200 further includes:

[0089] Step S220, obtaining the pressing parameter of the knob 12 detected by the knob detection structure 2, where the pressing parameter includes at least one of a long-press parameter and a short-press parameter.

[0090] In the embodiment of the present application, when the knob 12 is pressed along its own axis, the pressing detection component 23 can generate a corresponding pressing parameter, so that the knob detection structure 2 can detect the pressing parameter of the knob 12.

[0091] Exemplarily, when the user presses the knob 12 along the axis, the knob 12 can squeeze the conductive elastic sheet 233, so that the conductive elastic sheet 233 deforms in the direction close to the third electrical connector 231 and the fourth electrical connector 232 until the conductive elastic sheet 233 contacts the third electrical connector 231 and the fourth electrical connector 232, so that the third electrical connector 231 and the fourth electrical connector 232 are conducted through the conductive elastic sheet 233, so that the main control board 131 can obtain the pressing parameter.

[0092] Exemplarily, when the time for the user to press the knob 12 is less than or equal to the preset duration, the main control board 131 recognizes it as a short-press parameter, and when the time for the user to press the knob 12 is greater than the preset duration, the main control board 131 recognizes it as a long-press parameter. In the embodiment of the present application, the preset duration can be 0.5 seconds, 1 second, 1.5 seconds. In other embodiments, the preset duration can also be other durations.

[0093] Step S230, controlling the charging control unit 132 to work according to the rotation parameter and the pressing parameter.

[0094] In the embodiment of the present application, the main control board 131 can enter the editing mode of the charging information of the charging port 1321 according to the rotation parameter and the pressing parameter to edit the charging information of the charging port 1321; it can also enter the editing mode of the opening and closing of the charging control unit 132 to control the opening and closing of the charging control unit 132.

[0095] Exemplarily, the main control board 131 can perform several basic function selections such as selection, confirmation, and cancellation according to the obtained short-press parameter and display them on the display 134. The main control board 131 can also perform a factory reset on the charger 1 according to the obtained short-press parameter for a preset number of times, where the preset number of times can be 5 times or 6 times. The main control board 131 can also turn off the screen display function and wake up the display 134 according to the long-press parameter.

[0096] It can be understood that in other embodiments, the charging control unit 132 can also be controlled to work solely through the pressing parameter, which will not be elaborated here.
