[0027] The exemplary embodiments will be described in detail below with reference to the drawings. In the following description, the same numbers are used to denote the same elements throughout the several views. The following exemplary description is not representative of all embodiments consistent with the present disclosure. Rather, it is merely an example of devices consistent with some aspects of the present disclosure as detailed in the appended claims. It is noted that features of the below-described embodiments and implementations can be combined with each other, if not contradictory.

[0028] Currently, a light-emitting material, such as an electrochromic material, is arranged in the shell of an electronic device, and different colors are displayed by the light-emitting material to improve the aesthetics of the electronic device. Taking electrochromic as an example, different driving voltages are required for different light-emitting materials, which requires the power supply module to be able to provide different driving voltages, resulting in a relatively complex power supply module.

[0029] To solve the above technical problems, the electronic device provided by the embodiments of the present disclosure, as shown in Figure 1 , comprises a power supply module 1 and an electrochromic module 21 arranged on a shell 2. The shell 2 is provided with shell power supply ends (A and B) and shell identification ends (C and D), the shell power supply ends (A and B) are electrically connected with the electrochromic module, and the power supply module comprises module power supply ends (a and b) and module identification ends (c and d). When the shell 2 is fixed to the electronic device, the module identification ends of the power supply module 1 are electrically connected with the shell identification ends on the shell 2, that is, the module power supply end a is electrically connected with the shell power supply end A, the module power supply end b is electrically connected with the shell power supply end B, the module identification end c is electrically connected with the shell identification end C, and the module identification end d is electrically connected with the shell identification end D. In this way, the power supply module 1 can determine the driving voltage matched with the electrochromic module 21 through the voltage at the shell identification ends (C and D) of the shell 2, and output the driving voltage through the module power supply ends (c and d) to make the electrochromic module switch to the display state corresponding to the driving voltage.

[0030] It should be noted that the ground GND can be arranged on the mainboard of the electronic device, at this time the module identification end d can be arranged on the electronic device, so that the shell identification end D of the shell is grounded GND. In actual application, the ground GND can also be arranged on the shell 2, at this time the power supply module can not need to be provided with the module identification end d and the shell can not need to be provided with the shell identification end D, one set of identification ends can be omitted, the design difficulty and the reliability of electrical connection are reduced, and the effect is as shown in Figure 3 For convenience of description, the module identification end d and the shell identification end D are taken as examples to describe the schemes of the embodiments hereinafter.

[0031] In the embodiment, the power supply module can provide a matching driving voltage for different housings. For example, in a multiple-housing alternative assembly scenario, the power supply module can automatically correct the output voltage without manual correction of the output voltage of the driving circuit, thereby improving the efficiency of housing assembly on the electronic device.

[0032] Figure 2 FIG. 1 is a circuit schematic diagram of an electronic device according to an example embodiment, Figure 3 FIG. 2 is a circuit schematic diagram of another electronic device according to an example embodiment, Figure 4 FIG. 3 is a circuit schematic diagram of yet another electronic device according to an example embodiment. Referring to Figures 2-4 The housing 2 of the electronic device further includes an identification resistor 22. The housing identification end includes a first housing identification end (e.g., D end) and a second housing identification end (e.g., C end). The first end of the identification resistor 22 is electrically connected to the first housing identification end (e.g., D end) of the housing 2, and the second end of the identification resistor 22 is electrically connected to the second housing identification end (e.g., C end) of the housing 2. The resistance value of the identification resistor 22 is associated with the display state of the electrochromic module 21.

[0033] In the embodiment, the electrochromic module 21 can change from one display state to another display state, such as from displaying red to displaying white. Based on this, different electrochromic modules 21 can have different display states. For example, the same display state (e.g., displaying white) and different display states (e.g., displaying green, yellow, blue, or a combination of one or more colors) can be provided. In this scenario, different resistances can be matched to electrochromic modules 21 with different display states. For example, when the identification resistor 22 is 10 ohms, it corresponds to the electrochromic module 21 displaying red; when the identification resistor 22 is 20 ohms, it corresponds to the electrochromic module 21 displaying green; when the identification resistor 22 is 30 ohms, it corresponds to the electrochromic module 21 displaying yellow, and so on. Thus, an association between the resistance value of the identification resistor and the display state of the electrochromic module 21 can be established, i.e., the resistance value of the identification resistor is associated with the display state of the electrochromic module.

[0034] It can be understood that, considering that the resistance value of the identification resistor 22 is different, the voltage on the identification resistor 22 is also different; or in the case of the same power supply, an association between the voltage of the identification resistor 22, the resistance value, and the display state of the electrochromic module can be established. In subsequent embodiments, the voltage at the housing identification end, i.e., the voltage on the identification resistor 22, can be used to determine the matching driving voltage of the electrochromic module 21, i.e., to identify the housing 2. The skilled person can select to use the identification resistor according to the specific scenario, such as the current on the identification resistor, and the corresponding solution falls within the protection scope of the present disclosure.

[0035] In an embodiment, referring to Figures 2-4 , the electronic device comprises a power conversion circuit 11 which is electrically connected with a battery (not shown in the figure) in the electronic device. The power conversion circuit 11 is configured to convert a first voltage provided by the battery in the electronic device into a second voltage. It can be understood that the first voltage needs to exceed the driving voltage of the electrochromic module in different housings. The second voltage can be used as the driving voltage of the electrochromic module (as shown in Figure 2 and Figure 3 ) or a divided voltage of the second voltage is used as the driving voltage of the electrochromic module (as shown in Figure 4 ). In an example, the power conversion circuit 11 can comprise at least one of a linear voltage regulator LDO and a bridge circuit. The skilled person can select a suitable power conversion circuit according to the specific scenario, and the corresponding circuit falls within the protection scope of the present disclosure as long as the voltage conversion can be realized.

[0036] For the convenience of description, the power conversion circuit 11 adopts a linear voltage regulator LDO as an example to describe the schemes of various embodiments in the subsequent description. In an example, the linear voltage regulator LDO can output a fixed voltage, i.e., the second voltage is a fixed value and the divided voltage of the second voltage is used as the driving voltage of the electrochromic module. For example, the linear voltage regulator LDO can be used in the electronic device shown in Figure 2 to output a fixed voltage. In another example, the linear voltage regulator LDO can output a non-fixed voltage, i.e., the second voltage is a non-fixed value or a dynamic value which changes with the driving voltage of the electrochromic module. At this time, the second voltage can be used as the driving voltage of the electrochromic module. For example, the linear voltage regulator LDO can be used in the electronic device shown in Figure 4 to output a non-fixed voltage, i.e., a dynamic voltage. It should be noted that the non-fixed value or non-fixed voltage refers to that the linear voltage regulator LDO can output a fixed driving voltage which matches the housing for different housings, rather than outputting a fluctuating voltage for the housing after determining the housing.

[0037] In an embodiment, the power supply module can comprise a voltage dividing circuit. Referring to Figure 2 and Figure 3The first end of the voltage dividing circuit 12 is electrically connected with the power conversion circuit 11, the second end of the voltage dividing circuit 12 is electrically connected with the second shell identification end C of the shell 2, and the third end of the voltage dividing circuit 12 is electrically connected with the first shell power supply end A of the shell 2, so that the voltage dividing circuit 12 and the identification resistance in the shell 2 form a series voltage dividing circuit, and the voltage at the series connection position is the driving voltage matched with the electrochromic module 21. In an example, the voltage dividing circuit 12 can include a voltage dividing resistance R1, the first end of the voltage dividing resistance R1 is electrically connected with the first end of the voltage dividing circuit 12, and the second end of the voltage dividing resistance R1 is electrically connected with the second end and the third end of the voltage dividing circuit 12 respectively. The voltage dividing resistance R1 and the identification resistance Rid constitute a series voltage dividing circuit. In this way, when the resistance of the identification resistance Rid changes, the voltage dividing at the series connection position Pc1 of the above series voltage dividing circuit also changes, so that different driving voltages can be provided for the electrochromic module 21. It can be understood that the voltage dividing resistance R1 can have a value in the range of tens of ohms to tens of megohms, and in the case of being able to provide different driving voltages in cooperation with the identification resistance, the value of the voltage dividing resistance R1 can be adjusted according to specific scenarios.

[0038] In an embodiment, continuing to refer to Figure 2 and Figure 3 , the power supply module 1 further includes a voltage follower 13, the input end of the voltage follower 13 is electrically connected with the second end of the voltage dividing circuit 12, and the output end of the voltage follower 13 is electrically connected with the first shell power supply end A of the shell 2. Since the voltage follower 13 has a high input resistance and a low output resistance, it is open to the front-stage circuit and equivalent to a constant voltage source to the rear-stage circuit, so that the output voltage of the voltage follower 13 is not affected by the impedance in the rear-stage circuit, that is, the influence of the load (i.e. the electrochromic module) on the input end (i.e. the power conversion circuit) is isolated.

[0039] In an embodiment, continuing to refer to Figure 2 and Figure 3 , the power supply module 1 can further include a switching switch 14. The input end of the switching switch 14 is electrically connected with the second end of the voltage follower 13 or the voltage dividing circuit 12, the output end of the switching switch 14 is electrically connected with the shell power supply end (A and B), and the control end (not shown in the figure) of the switching switch 14 is used to receive a control signal. The switching switch 14 is used to switch to the working state corresponding to the control signal when the control signal is received, so that the display state of the electrochromic module is switched to the display state corresponding to the driving voltage.

[0040] It should be noted that the above-mentioned switching switch 14 can be a double-pole double-throw switch, the first input end and the fourth input end of the double-pole double-throw switch are electrically connected with the voltage follower 13, the second input end and the third input end of the double-pole double-throw switch are grounded, and the first output end and the second output end of the double-pole double-throw switch are electrically connected with the shell power supply end A and the shell power supply end B, respectively. When the double-pole double-throw switch is in the first state (as shown in Figure 2 and Figure 3 ), a forward driving voltage can be provided to the electrochromic module 21, and when the double-pole double-throw switch is in the second state (as shown in Figure 2 and Figure 3 ), a reverse driving voltage can be provided to the electrochromic module 21. In this way, in the present example, the state switching of the switching switch 14 can provide the electrochromic module 21 with a driving voltage of the same size but opposite direction, so as to switch the display state of the electrochromic module to the display state corresponding to the driving voltage.

[0041] In an embodiment, continuing to refer to Figure 4 , the power supply module 1 can include a voltage dividing circuit 12. The first end of the voltage dividing circuit 12 is electrically connected with the power supply conversion circuit 11 and the first shell power supply end A of the shell 2, respectively, and the second end of the voltage dividing circuit 12 is electrically connected with the second shell identification end C of the shell 2, so that the voltage dividing circuit 12 forms a series voltage dividing circuit with the identification resistor Rid in the shell 2, and the voltage at the starting position Pc2 of the series voltage dividing circuit is the driving voltage matched with the electrochromic module 21. In an example, the voltage dividing circuit 12 can include a voltage dividing resistor R1, and the voltage dividing resistor R1 and the identification resistor Rid constitute a series voltage dividing circuit. In this way, when the resistance of the identification resistor Rid changes, the voltage dividing at the series position Pc2 of the above-mentioned series voltage dividing circuit also changes, so as to provide different driving voltages for the electrochromic module 21. It can be understood that the voltage dividing resistor R1 can have a value in the range of tens of ohms to tens of megohms, and in the case of being able to provide different driving voltages in cooperation with the identification resistor, the value of the voltage dividing resistor R1 can be adjusted according to specific scenarios.

[0042] In an embodiment, continuing to refer to Figure 4 , when the second voltage is a non-fixed value and the second voltage is the above-mentioned driving voltage, the above-mentioned power supply conversion circuit 11 further includes a feedback end FB. The feedback end FB is electrically connected with the second end of the voltage dividing circuit 12, so that the voltage dividing circuit 12 forms a series voltage dividing circuit with the identification resistor Rid in the shell 2, and the current at the series position Pc1 is used to determine the driving voltage matched with the electrochromic module. For example, when the power supply conversion circuit 11 adopts a linear voltage regulator LDO with an adjustable output voltage, the output voltage of the linear voltage regulator LDO is:

[0043]

[0044] wherein Vout represents the output voltage of the LDO; V0 represents a fixed value, such as 200 mV; I FB represents the current at the feedback end.

[0045] It can be understood that when different housings are fixed to the electronic device, the identification resistance in the housing 2 is different, at this time the LDO can adjust the size of the output voltage Vout, so that the voltage at the feedback end FB is a fixed value. In other words, the LDO can determine the driving voltage matched with the electrochromic module through the current at the series connection position Pc1. In this way, the power supply module 1 achieves the effect of providing different output voltages for different housings 2.

[0046] In an embodiment, continuing to refer to Figure 3 , the power supply module 1 can further include a switching switch 14. The input end of the switching switch 14 is electrically connected with the first end of the voltage dividing circuit 12, and the output end of the switching switch 14 is electrically connected with the housing power supply end (A and B); the control end (not shown in the figure) of the switching switch 14 is used for receiving a control signal. The switching switch 14 is used for switching to the working state corresponding to the control signal when receiving the control signal, so as to make the display state of the electrochromic module switch to the display state corresponding to the driving voltage.

[0047] It should be noted that the above-mentioned switching switch 14 can be a double-pole double-throw switch, the first input end and the fourth input end of the double-pole double-throw switch are electrically connected with the first end of the voltage dividing circuit 12, the second input end and the third input end of the double-pole double-throw switch are grounded, and the first output end and the second output end of the double-pole double-throw switch are respectively electrically connected with the housing power supply end A and the housing power supply end B. The double-pole double-throw switch can provide a forward driving voltage to the electrochromic module 21 in the first state (as shown in Figure 4 ), and can provide a reverse driving voltage to the electrochromic module 21 in the second state (not shown in Figure 4 ). In this way, in the present example, the double-pole double-throw switch can provide a driving voltage with equal size but opposite direction to the electrochromic module 21 through the state switching of the switching switch 14, so as to make the display state of the electrochromic module 21 switch to the display state corresponding to the above-mentioned driving voltage.

[0048] It should be noted that the switching switch 14 can also be integrated into the shell 2. When the switching switch 14 is a double-pole double-throw switch, the first input end and the fourth input end of the double-pole double-throw switch are electrically connected with the shell power supply end A, the second input end and the third input end of the double-pole double-throw switch are electrically connected with the shell power supply end B, and the shell power supply end B can be grounded, and the first output end and the second output end of the double-pole double-throw switch are respectively electrically connected with the electrochromic module. After being integrated into the shell 2, the working mode of the double-pole double-throw switch integrated into the working mode of the power supply module 1 is similar, and will not be described here. In this example, by integrating the switching switch into the shell, the complexity of the power supply module can be reduced.

[0049] In an embodiment, the electronic device further includes a processor (not shown in the figure) electrically connected with the control end of the switching switch 14, for obtaining a service scenario in the electronic device, including but not limited to playing audio and video, incoming call reminder, short message reminder, missed call, unread information, etc. Then, the electronic device can determine the control signal corresponding to the service scenario, and output the control signal to the switching switch, so as to switch the switching switch to the target state, so as to output the positive or negative output voltage. In this way, the electronic device in this embodiment can control the switching switch through the processor, so as to control the electrochromic module to switch the display state.

[0050] The working process of the power supply module adjusting the voltage when the shell is fixed to the electronic device will be described below in combination with Figure 2 and Figure 3

[0051] When the shell 2 is fixed to the middle frame of the electronic device, the module identification end and the module power supply end on the power supply module 1 are respectively electrically connected with the shell identification end and the shell power supply end on the shell 2. At this time, the voltage V1 at the series connection position Pc1 of the voltage dividing resistor R1 and the identification resistor Rid is Vout*Rid / (Rid+R1) when the output voltage of the linear voltage regulator LDO is a fixed value. That is, the power supply module 1 can provide a driving voltage V1 to the shell 2 to drive the electrochromic module to switch the display state.

[0052] The working process of the power supply module adjusting the voltage when the shell is fixed to the electronic device will be described below in combination with Figure 4

[0053] ​​When the shell 2 is fixed to the middle frame of the electronic device, the module identification end and the module power supply end on the power supply module 1 are respectively electrically connected with the shell identification end and the shell power supply end on the shell 2. At this time, the voltage dividing resistor R1 and the identification resistor Rid form a series voltage dividing circuit. Since the voltage at the feedback end FB of the linear voltage regulator LDO is a fixed value, when different shells are fixed to the middle frame to cause the identification resistor Rid to change, the linear voltage regulator LDO will adjust the output voltage Vout so that the voltage at the feedback end FB is always a fixed value. That is, the power supply module 1 can provide a matching driving voltage Vout to the shell 2 to drive the electrochromic module to switch the display state.
