[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0034] In recent years, with the rapid development of related technologies such as electronic equipment development and preparation, electronic devices with multiple functions such as mobile phones and tablet computers have been widely used in people's daily lives. Electronic devices are usually equipped with different types of interfaces such as TYPE-C, which are used to connect to charging power supplies or other electronic devices to achieve some inherent functions of electronic devices such as wired charging or data transmission.

[0035] However, after electronic devices are manufactured and shipped out of the factory, the functions that can be realized by the electronic devices are limited due to the limitations of their own hardware structure. It is difficult to expand and upgrade the functions of the device through the electronic devices themselves. For example, some mobile phones cannot realize the wireless charging function due to the lack of wireless charging ports, which cannot meet the users' growing and rapidly iterating functional needs, and the user experience is poor.

[0036] Based on this, an exemplary embodiment of the present disclosure provides an accessory for an electronic device, which enables the accessory of the electronic device to be connected to the electronic device by setting an interface structure, and enables the functional module of the accessory to transmit power and signals to the electronic device, so as to perform predetermined functions other than the inherent functions of the electronic device through the functional module, thereby expanding the functions of the electronic device and improving the user experience.

[0037] In an exemplary embodiment, reference Figure 1 As shown, an accessory for an electronic device is provided. The electronic device may be, for example, a mobile phone, a tablet computer, an electronic watch, or other device having an interface of a certain form. The accessory for the electronic device includes a functional module 10 and an interface structure 20. The interface structure 20 is connected to the functional module 10. The interface structure 20 is used to connect to the interface of the electronic device. The functional module 10 can transmit electric energy or signals to the electronic device through the interface structure 20. The functional module 10 can also transmit electric energy and signals to the electronic device through the interface structure 20 so that the functional module 10 performs a predetermined function.

[0038] The interface structure 20 of the accessory is adapted to the interface of the electronic device. The interface structure 20 of the accessory can be one or more. When the interface structure 20 of the accessory is multiple, the interface structure 20 can have multiple different types to connect with different electronic device interfaces. When the interface structure 20 of the accessory is connected to the interface of the electronic device, the functional module 10 of the accessory can transmit power and signals to the electronic device through the interface structure 20 connected thereto. The transmission of power and signals between the functional module 10 and the electronic device can be bidirectional, that is, the functional module 10 can send power and signals to the electronic device, and the functional module 10 can also receive power and signals sent by the electronic device.

[0039] The functional module 10 may include, for example, a plurality of modules, and the functional module 10 may perform different predetermined functions by transmitting power and signals with the electronic device, so that the electronic device can achieve the expansion of the function of the electronic device through the accessory after being connected to the accessory. Exemplarily, the functional module 10 may perform the charging function of the electronic device by transmitting power to the electronic device, and the functional module 10 may also perform the external charging function by receiving the power transmitted by the electronic device and outputting it externally.

[0040] In this embodiment, by setting up an interface structure 20, the accessory of the electronic device can be connected to the interface of the electronic device through the interface structure 20, and the functional module 10 of the accessory can transmit power and signals to the electronic device, so that the functional module 10 can execute predetermined functions other than the inherent functions of the electronic device, thereby realizing the expansion of the functions of the electronic device and improving the user experience.

[0041] In some embodiments, reference Figure 2 As shown, the functional module 10 includes a charging module 30, which is used to receive electric energy and transmit the received electric energy to the electronic device through the interface structure 20, and the charging module 30 is used to receive the electric energy transmitted by the electronic device through the interface structure 20 and charge the electronic device externally.

[0042] The functional module 10 includes a charging module 30, which can receive and send electric energy. The charging module 30 can receive electric energy and transmit the received electric energy to the electronic device through the interface structure 20 to perform the charging function of the electronic device. The electric energy received and transmitted by the charging module 30 can be electric energy transmitted by other devices in a wired manner through other interface structures 20, or it can be electric energy directly received by the charging module 30 in a wireless manner, that is, electric energy can be received in a wired manner through an accessory, or it can be received in a wireless manner, which realizes the expansion of the wireless charging function for electronic devices that do not have a wireless charging function.

[0043] The charging module 30 can also receive electric energy transmitted by the electronic device through the interface structure 20. After receiving the electric energy transmitted by the electronic device, the charging module 30 can store the received electric energy and transmit the stored electric energy to other devices in a wired manner through the interface structure 20. The stored electric energy can also be directly transmitted to other devices wirelessly through the charging module 30 to perform the external charging function for other devices.

[0044] In this embodiment, by setting a charging module 30 in the functional module 10, it is possible to receive electric energy through the charging module 30 and transmit the received electric energy to the electronic device through the interface structure 20, and it is also possible to receive electric energy transmitted by the electronic device through the interface structure 20 and charge the external device, so that the functional module 10 can perform the charging function of the electronic device and the external charging function of other devices, thereby realizing the expansion of the charging-related functions of the electronic device and improving the user experience.

[0045] In some embodiments, reference Figure 2 As shown, the charging module 30 includes a wireless charging and discharging coil 31 .

[0046] The wireless charging and discharging coil 31 is arranged in the charging module 30. The wireless charging and discharging coil 31 can generate an alternating electromagnetic field based on electromagnetic wave induction to output electric energy wirelessly. The wireless charging and discharging coil 31 can also induce an alternating electromagnetic field signal to receive electric energy wirelessly, and the transmission of electric energy can be achieved without the need for connecting wires.

[0047] Exemplarily, the wireless charging and discharging coil 31 can receive electric energy wirelessly transmitted by other devices such as a wireless charging base, and transmit the received electric energy to the electronic device through the interface structure 20 to perform the charging function of the electronic device. The wireless charging and discharging coil 31 can also receive electric energy transmitted by the electronic device through the interface structure 20, and transmit the received electric energy wirelessly to other devices to perform the external charging function of other devices.

[0048] In this embodiment, by setting a wireless charging and discharging coil 31 in the charging module 30, the charging module 30 can receive and send electric energy, so that electric energy can be transmitted between the accessory and the electronic device or other devices in a wireless manner, and can receive electric energy in a wireless manner and perform the charging function of the electronic device, or send electric energy in a wireless manner to perform the external charging function of other devices. The accessory can expand the wireless charging function when the electronic device itself does not have the wireless charging function, thereby improving the user experience.

[0049] In some embodiments, reference Figure 2 As shown, the functional module 10 includes a power module 40 , and the interface structure 20 is used to receive electric energy transmitted by the electronic device and supply power to the power module 40 .

[0050] The functional module 10 may also include a power module 40. After the interface structure 20 of the accessory is connected to the interface of the electronic device, the interface structure 20 can receive the electric energy transmitted by the electronic device and transmit the electric energy to the power module 40. The power module 40 can receive the electric energy supplied by the interface structure 20 to perform predetermined functions that require consumption of electric energy.

[0051] The power module 40 may include a load unit for providing the overall load of the accessory, or one or more auxiliary function units for implementing other auxiliary functions. Exemplarily, the power module 40 may include a load unit and an auxiliary function unit for implementing the flashing of an indicator light, and the interface structure 20 receives the power transmitted by the electronic device and supplies power to the power module 40, so that the power module 40 can perform the load function and other auxiliary functions such as the flashing of an indicator light.

[0052] In this embodiment, by setting a power consumption module 40 in the functional module 10, the electric energy transmitted by the electronic device received by the interface structure 20 can be provided to the power consumption module 40, so that the power consumption module 40 can execute other predetermined functions that require consumption of electric energy through the electric energy supplied by the interface structure 20. The power consumption module 40 can be set accordingly according to the requirements of the predetermined functions, thereby realizing the expansion of the power consumption-related functions of the electronic device and improving the user experience.

[0053] It should be noted that the power module 40 can be connected to the charging module 30. When the power module 40 is connected to the charging module 30, the wireless charging and discharging coil 31 of the charging module 30 can directly supply power to the power module 40 through the charging module 30 after receiving external electric energy wirelessly, so that the power module 40 can consume the electric energy received wirelessly by the charging module 30 to perform the corresponding predetermined function.

[0054] In some embodiments, reference Figure 1 As shown, the interface structure 20 includes a male interface 50 and a female interface 60 , wherein the male interface 50 is used to connect to an interface of an electronic device, and the female interface 60 is used to connect to a switching device.

[0055] When there are multiple interface structures 20, a male interface 50 and a female interface 60 can be provided at the same time. The male interface 50 can be directly inserted into the interface of the electronic device to achieve the connection between the accessory and the electronic device. The female interface 60 can be connected to one end of another adapter device with a male form, and the adapter device can be used to achieve the connection with the electronic device or other devices at the other end of the adapter device. When the accessory is connected to the electronic device through the male interface 50, the male interface 50 can transmit power to the electronic device or receive power transmitted by the electronic device to perform the charging function of the electronic device or the external charging function. When the accessory is connected to the adapter device through the female interface 60, the female interface 60 and the adapter device can transmit power to other devices to perform the external charging function of other devices.

[0056] Exemplarily, the interface structure 20 includes a TYPE-C male interface 50 and a female interface 60. The male interface 50 can be connected to a mobile phone having a TYPE-C female interface 60. The female interface 60 can be connected to a power cord or other adapter having a TYPE-C male interface 50 at one end, and can be connected to a mobile phone or other device at the other end of the power cord through the power cord. It is understandable that the female interface 60 can also be directly connected to any device having an adaptable male interface.

[0057] In this embodiment, by setting male interfaces 50 and female interfaces 60 of different shapes, connection with an interface of an electronic device or a converter device can be achieved, that is, connection with the electronic device can be achieved through direct and indirect methods, so that the accessory can be suitable for electronic devices with different interfaces, thereby improving the applicability of the interface structure 20 and the accessory.

[0058] In some embodiments, reference Figure 3As shown, the accessory of the electronic device also includes a control module 70 and a switch assembly 80 electrically connected to the control module 70 , and the switch assembly 80 is used to control the on-off between the functional module 10 and the male interface 50 , and the on-off between the functional module 10 and the female interface 60 .

[0059] The accessory of the electronic device also includes a control module 70 and a switch component 80 electrically connected to the control module 70. The control module 70 can be, for example, a microcontroller unit (MCU). The switch component 80 is arranged between the functional module 10 and the male interface 50 and the female interface 60. The control module 70 can control the opening and closing of the switch component 80 according to the connection status of the interface structure 20 of the accessory, so as to control the connection and disconnection between the functional module 10 and the male interface 50 and the female interface 60 through the switch component 80, so that the functional module 10 can perform the corresponding predetermined function through different power transmission paths and directions.

[0060] Exemplarily, when it is necessary to perform the charging function of the electronic device, the control module 70 can control the switch assembly 80 to make the connection state between the functional module 10 and the male interface 50, and make the connection state between the functional module 10 and the female interface 60, and transmit electric energy to the male interface 50 through the charging module 30 in the functional module 10, so that the male interface 50 can realize the charging function of the electronic device by connecting with the electronic device.

[0061] When the external charging function needs to be executed, the control module 70 can first control the switch component 80 to make the functional module 10 and the male interface 50 in a connection state, and make the functional module 10 and the female interface 60 in a disconnected state, and receive the electric energy transmitted by the electronic device through the male interface 50 through the charging module 30 in the functional module 10, and then control the switch component 80 to make the functional module 10 and the male interface 50 in a disconnected state, and make the functional module 10 and the female interface 60 in a connection state, and transmit the electric energy received by the charging module 30 to the female interface 60, so that the female interface 60 can realize the external charging function through the adapter.

[0062] When other auxiliary functions need to be performed, the control module 70 can be used to control the switch assembly 80 so that the functional module 10 and the male interface 50 are in a connection state, and the functional module 10 and the female interface 60 are in a disconnection state. The power module 40 in the functional module 10 receives the electric energy transmitted by the electronic device through the male interface 50, and the male interface 50 supplies power to the power module 40, so as to realize other auxiliary functions through the power module 40.

[0063] In this embodiment, by setting a control module 70 and a switch assembly 80 in the accessory, the control module 70 and the switch assembly 80 can control the on / off connection between the functional module 10 and the male interface 50 and the female interface 60, so that the functional module 10 can perform the corresponding predetermined function through different power transmission paths and directions, thereby realizing the control and selection of the predetermined function, providing conditions for the expansion of the functions of the electronic device, and improving the user experience.

[0064] In some embodiments, reference Figure 3 As shown, the switch component 80 includes a first transistor 81 and a second transistor 82, the first end of the first transistor 81 is electrically connected to the functional module 10, the second end of the first transistor 81 is electrically connected to the first terminal VBUS1 of the male interface 50, the control end of the first transistor 81 is electrically connected to the control module 70, and the first terminal VBUS1 is used for power transmission; the first end of the second transistor 82 is electrically connected to the functional module 10, the second end of the second transistor 82 is electrically connected to the second terminal VBUS2 of the female interface 60, the control end of the second transistor 82 is electrically connected to the control module 70, and the second terminal VBUS2 is used for power transmission.

[0065] The first end of the first transistor 81 is electrically connected to the functional module 10, and the second end of the first transistor 81 is electrically connected to the first terminal VBUS1 of the male interface 50. The first terminal VBUS1 of the male interface 50 is used for power transmission. The power transmitted by the first terminal VBUS1 can be the power transmitted from the accessory to the electronic device, or the power transmitted from the electronic device to the accessory. The first transistor 81 is arranged between the functional module 10 and the male interface 50, and the control end of the first transistor 81 is electrically connected to the control module 70. The control module 70 can control the opening and closing of the first transistor 81 and the current direction of the first transistor 81 when the first transistor 81 is turned on, so as to realize that the switch component 80 controls the on-off between the functional module 10 and the male interface 50.

[0066] The first end of the second transistor 82 is electrically connected to the functional module 10, and the second end of the first transistor 81 is electrically connected to the second terminal VBUS2 of the female interface 60. The second terminal VBUS2 of the female interface 60 is used for power transmission. The power transmitted by the second terminal VBUS2 can be the power transmitted from the accessory to other devices, or the power transmitted from other devices to the accessory. The second transistor 82 is arranged between the functional module 10 and the female interface 60, and the control end of the second transistor 82 is electrically connected to the control module 70. The control module 70 can control the opening and closing of the second transistor 82 and the direction of the current passing through the second transistor 82 when the second transistor 82 is turned on, so as to realize that the switch component 80 controls the on-off between the functional module 10 and the female interface 60.

[0067] For example, Figure 3 As shown, the first transistor 81 and the second transistor 82 can be, for example, P-type field effect transistors (Positive Channel Metal Oxide Semiconductor, PMOS), the number of the first transistor 81 and the second transistor 82 can be two, the directions of the body diodes of the two first transistors 81 are opposite, and the directions of the body diodes of the two second transistors 82 are opposite, so that the first transistor 81 and the second transistor 82 can both achieve the effect of preventing current backflow.

[0068] In this embodiment, by setting the first transistor 81 and the second transistor 82, and making the control ends of the first transistor 81 and the second transistor 82 electrically connected to the control module 70, the on-off between the functional module 10 and the male interface 50 can be controlled by the control module 70 and the first transistor 81, and the on-off between the functional module 10 and the female interface 60 can be controlled by the control module 70 and the second transistor 82, thereby realizing the control effect of the switch component 80, so that the functional module 10 can perform the corresponding predetermined function through different power transmission paths and directions, realizing the control and selection of the predetermined function, providing conditions for the expansion of the functions of electronic equipment, and improving the user experience.

[0069] In some embodiments, reference Figure 4 As shown, the accessories of the electronic device also include multiple power supply branches for supplying power to the control module 70, one end of each power supply branch is connected to at least one of the first terminal VBUS1 and the second terminal VBUS2, and the other end of each power supply branch is connected to the control module 70. The control module 70 is used to select a power supply branch to supply power to the control module 70 according to the voltage of the first terminal VBUS1 and the second terminal VBUS2.

[0070] The power supply branch is used to supply power to the control module 70. One end of each power supply branch can be connected to the first terminal VBUS1 of the male interface 50 or the second terminal VBUS2 of the female interface 60. One end of each power supply branch can also be simultaneously connected to the first terminal VBUS1 of the male interface 50 and the second terminal VBUS2 of the female interface 60. The other end of each power supply branch is connected to the control module 70, so that the electric energy transmitted by the first terminal VBUS1 or the second terminal VBUS2 can be delivered to the control module 70 to realize power supply to the control module 70.

[0071] Different power supply branches have different voltages at one end connected to the control module 70. The control module 70 can select a power supply branch to supply power to the control module 70 according to the voltages of the first terminal VBUS1 and the second terminal VBUS2, so that the voltage at one end of the power supply branch connected to the control module 70 is a voltage that matches the voltage of the normal working state of the control module 70. Exemplarily, when only one of the first terminal VBUS1 and the second terminal VBUS2 has a voltage, a suitable power supply branch can be selected according to the voltage of the terminal to adjust the voltage. When both the first terminal VBUS1 and the second terminal VBUS2 have voltages, the voltages of the two terminals can be selected and adjusted by selecting different power supply branches.

[0072] In this embodiment, by setting up multiple power supply branches for supplying power to the control module 70, and making the two ends of each power supply branch connected to the control module 70 and at least one of the first terminal VBUS1 and the second terminal VBUS2 respectively, the control module 70 can select a power supply branch to power the control module 70 according to the voltage of the first terminal VBUS1 and the second terminal VBUS2, so that the voltage provided to the controlled module can be adapted to the normal working voltage of the control module 70, thereby ensuring the stable operation of the control module 70, and further ensuring the stability of the on-off control between the functional module 10 and the interface structure 20.

[0073] In some embodiments, reference Figure 4 As shown, the multiple power supply branches include a first power supply branch 91, a second power supply branch 101 and a third power supply branch 111, and one end of each power supply branch is connected to both the first terminal VBUS1 and the second terminal VBUS2, wherein a first voltage converter 102 is provided on the second power supply branch 101, and a second voltage converter 112 is provided on the third power supply branch 111, the first voltage converter 102 is used for step-down, and the second voltage converter 112 is used for step-up.

[0074] There are three power supply branches, and the first ends of the three power supply branches are connected to the first terminal VBUS1 and the second terminal VBUS2 at the same time. The second power supply branch 101 is provided with a first voltage converter 102, and the first voltage converter 102 is used for voltage reduction. When the second power supply branch 101 is selected to supply power to the control module 70, the first voltage converter 102 can reduce the higher voltage at the first terminal VBUS1 or the second terminal VBUS2 to the voltage of the adaptation control module 70. The third power supply branch 111 is provided with a second voltage converter 112, and the second voltage converter 112 is used for voltage boosting. When the third power supply branch 111 is selected to supply power to the control module 70, the second voltage converter 112 can increase the lower voltage at the first terminal VBUS1 or the second terminal VBUS2 to the voltage of the adaptation control module 70.

[0075] In this embodiment, by setting three power supply branches, and setting a first voltage converter 102 for voltage reduction on the second power supply branch 101, and setting a second voltage converter 112 for voltage boost on the third power supply branch 111, the voltage can be reduced or increased by selecting the second power supply branch 101 or the third power supply branch 111, so that the voltage provided to the control module 70 can be adapted to the control module 70, ensuring the stable operation of the control module 70, thereby ensuring the stability of the on-off control between the functional module 10 and the interface structure 20.

[0076] In some embodiments, reference Figure 4 As shown, one end of the first power supply branch 91 is connected to the first terminal VBUS1, and the other end of the first power supply branch 91 is connected to the control module 70 through the first unidirectional device 92.

When the first terminal VBUS1 or the second terminal VBUS2 has a voltage and both have a voltage at the same time, and the higher voltage is higher than the adaptation voltage of the control module 70, the voltage can be stepped down by selecting the second power supply branch 101 to provide the adapted voltage to the control module 70.

The number of the fifth transistor 116 may be two, and the directions of the body diodes of the two fifth transistors 116 are opposite, so that the fifth transistor 116 can achieve the effect of preventing current backflow. The voltage of the first terminal VBUS1 can be input to the third voltage converter 113 through the fifth transistor 116, so as to finally pass into the power module 40 and the third power supply branch 111, and the voltage of the second terminal VBUS2 can also be passed into the first power supply branch 91 through the fifth transistor 116, that is, the first power supply branch 91 and the third power supply branch 111 can be connected to the first terminal VBUS1 and the second terminal VBUS2 at the same time.
