After the repair is completed, the SIM card needs to be removed and the eSIM card needs to be reconnected. Exemplarily, the situation that the electronic device needs to receive the mobile signal through the SIM card may be that the electronic device needs to be repaired due to a problem with the eSIM card, or the electronic device needs to be certified and tested, or after the electronic device is rented out, other users need to use the SIM card.

It can be understood that, the embedded customer identification card (eSIM card) is a chip fixed in the electronic device, and the plug-in customer identification card (SIM card) is installed in the electronic device in a pluggable manner.

Please refer to FIG. 3 . FIG. 3 is a schematic diagram of a third structure of an electronic device provided by an embodiment of the present application. The card holder 380 includes a detection part 382. When the card holder 380 is not electrically connected to the plug-in customer identification card, such as when the plug-in customer identification card is not inserted into the card holder, the level of the detection part 382 is the first level. When the plug-in customer identification card is electrically connected, such as when the plug-in customer identification card is inserted into the deck, the level of the detection unit 382 is the second level, and the second level is different from the first level.

The control terminal 348 is electrically connected to the detection part 382. When the level of the detection part 382 is the first level, the control terminal 348 controls the fixed connection terminal 342 to conduct with the first connection terminal 344. When the level of the detection part 382 is the second level When the level is high, the control terminal 348 controls the connection between the fixed connection terminal 342 and the second connection terminal 346 .

The control terminal 348 of the switch 340 can determine whether the card socket port is electrically connected to the plug-in customer identification card through the level of the detection part 382 of the card holder 380, and then the control terminal 348 can control the fixed connection terminal 342 to select the first connection terminal 344 or The second connection end 346 is turned on, so that the radio frequency chip 320 is electrically connected to the plug-in customer identification card or the embedded customer identification card 360 . Specifically, when it is determined that the card holder 380 is electrically connected to the plug-in customer identification card, the control switch 340 enables the radio frequency chip 320 to be electrically connected to the plug-in customer identification card, that is, the mobile signal is received through the plug-in customer identification card. When it is not electrically connected with the plug-in customer identification card, the control switch 340 makes the radio frequency chip 320 electrically connect with the embedded customer identification card 360 , that is, the mobile signal is received through the embedded customer identification card 360 . The control terminal 348 of the switch 340 is directly electrically connected to the detection part 382 of the card holder 380 , and the switch 340 can be switched quickly according to the level of the detection part 382 , and the switching speed is fast with almost no time delay in between.

There are various ways to determine whether the card holder 380 is electrically connected to the plug-in customer identification card through the level change of the detection part 382 of the card holder 380 . Exemplarily, the detection part 382 of the card holder 380 can be used to change the level after being electrically connected with the plug-in customer identification card. For example, when no SIM card is inserted into the electronic device 1, the detection part 382 of the card holder 380 is disconnected to a low level; when the SIM card is inserted into the electronic device 1, the detection part 382 of the card holder 380 is electrically connected to the SIM card and becomes high level. In another example, the detection part 382 of the card holder 380 can be used to change the level through physical changes in which the plug-in customer identification card is inserted and pulled out of the card holder. For example, when no SIM card is inserted into the electronic device 1, the detection part 382 of the card holder 380 is electrically connected to a certain interface, so that the level of the detection part 382 is low level; when the SIM card is inserted into the electronic device 1, the card holder 380 The detection unit 382 of the device is disconnected from a certain interface, and the level of the detection unit 382 is changed to a high level.

Wherein, after the fixed connection end 342 and the second connection end 346 are connected, the radio frequency chip 320 receives the mobile signal through the plug-in customer identification card. If the plug-in customer identification card is invalid (for example, the card is a discarded card, an incompatible card, a card with damaged internal circuits, a card that is not installed properly, etc.), the radio frequency chip 320 cannot receive mobile signals through the plug-in customer identification card, and the electronic device 1 has been switched to the radio frequency chip 320 to be electrically connected to the plug-in customer identification card, then the electronic device 1 cannot work normally. In this embodiment, the radio frequency chip 320 can detect whether the plug-in customer identification card is an invalid card. If the plug-in customer identification card is detected as an invalid card, it controls the connection between the fixed connection end 342 and the first connection end 344, that is, switches to Receive mobile signal via eSIM.

The radio frequency chip 320 can detect whether the plug-in customer identification card is an invalid card through the current value or voltage value in the circuit connected with the plug-in customer identification card. If the current value or voltage value in the circuit exceeds the normal range, it is considered that the plug-in customer The identification card is invalid. It is also possible to use the signal sent or received through the plug-in customer identity card to detect whether the plug-in customer identity card is invalid. It is also possible to detect whether the plug-in customer identity card is an invalid card by detecting the strength of the signal sent by the plug-in customer identity card.

Please refer to FIG. 4 , which is a schematic diagram of a fourth structure of an electronic device provided by an embodiment of the present application. The first level is lower than the second level. When the SIM card is not inserted into the electronic device 1, the detection unit 382 of the card holder 380 is at a low level. When the SIM card is inserted into the electronic device 1, the detection unit 382 of the card holder 380 is at a high level. . The electronic device 1 further includes a first resistor 372 and a ground terminal 374 , the detection part 382 is connected to the ground terminal 374 through the first resistor 372 , the radio frequency chip 320 includes a control pin 322 , and the control pin 322 is connected to the detection part 382 and the first resistor 372 between. Since the detection unit 382 is grounded through the first resistor 372, when the detection unit 382 is pulled down, the voltage of the detection unit 382 will not be 0. At this time, the detection part 382 at a low level can be pulled up through the control pin 322, and the first resistor 372 can make the level value of the detection part 382 more stable.

Optionally, the control pin 322 can be an output pin. After the fixed connection terminal 342 and the second connection terminal 346 are connected, if the radio frequency chip 320 detects that the plug-in customer identification card is an invalid card, the control pin 322 outputs a third level, and the third level is lower than the second level. level, so that the control terminal 348 controls the fixed connection terminal 342 to switch to conduct with the first connection terminal 344 according to the third level.

When the plug-in customer identification card is invalid, the radio frequency chip 320 can control the switch 340 through the control pin 322, so that the invalid plug-in customer identification card connected with the radio frequency chip 320 can be switched to the eSIM card, which effectively solves the problem of plug-in customer identification. The card is invalid card problem.

For example, when the SIM card is inserted into the electronic device 1, the detection part 382 of the card holder 380 is at a high level, the detection part 382 is electrically connected to the control terminal 348, and the control terminal 348 is also at a high level, thereby controlling the connection between the fixed connection terminal 342 and the third terminal 348. The two connection terminals 346 are connected to make the radio frequency chip 320 communicate with the SIM card. After the radio frequency chip 320 is connected with the SIM card, the radio frequency chip 320 detects that the SIM card is an invalid card, and then controls the control pin 322 to output a low level such as a third level, and the control pin 322 outputs the third level and can be pulled down to control The level of the terminal 348 makes the control terminal 348 a low level, thereby controlling the fixed connection terminal 342 to be switched to be connected to the first connection terminal 344, so that the radio frequency chip 320 is connected to the eSIM card.

Optionally, the control pin 322 can also be an input and output pin. When the electronic device 1 is powered on, the control pin 322 is in the input state, and the level of the detection part 382 is acquired; after the fixed connection end 342 and the second connection end 346 are connected, if the radio frequency chip 320 detects the plug-in client If the identification card is an invalid card, the control pin 322 is in an output state and outputs a third level, and the third level is lower than the second level, so that the control terminal 348 controls the fixed connection terminal 342 to switch to and from the third level according to the third level. The first connection terminal 344 is turned on.

The radio frequency chip 320 can obtain the information that the SIM card is inserted into the electronic device 1 through the control pin 322. When the radio frequency chip 320 recognizes that the plug-in customer identification card is an invalid card, it can control the switch 340 through the control pin 322, so that the radio frequency chip 320 can control the switch 340. The invalid plug-in customer identification card connected by 320 is switched to the eSIM card, which effectively solves the problem that the plug-in customer identification card is invalid.

For example, when the SIM card is inserted into the electronic device 1, the detection part 382 of the card holder 380 is at a high level, the detection part 382 is electrically connected to the control terminal 348, and the control terminal 348 is also at a high level, thereby controlling the connection between the fixed connection terminal 342 and the third terminal 348. The two connection terminals 346 are connected to make the radio frequency chip 320 communicate with the SIM card. At the same time, the control pin 322 of the radio frequency chip 320 is in an input state, and the control pin 322 can obtain the high level of the detection part 382 , thereby determining that a SIM card is inserted into the electronic device 1 . After the radio frequency chip 320 is connected with the SIM card, if the radio frequency chip 320 detects that the SIM card is an invalid card, the control pin 322 is in an output state, and outputs a low level such as a third level, and the control pin 322 outputs the third level. The level can pull down the level of the control terminal 348, so that the control terminal 348 is at a low level, so as to control the fixed connection terminal 342 to switch to the first connection terminal 344, so that the radio frequency chip 320 is connected to the eSIM card.

Please refer to FIG. 5 , which is a schematic diagram of a fifth structure of an electronic device provided by an embodiment of the present application. The radio frequency chip 320 includes a detection pin 324 and a control pin 322, the detection pin 324 is electrically connected with the detection part 382, and obtains the level of the detection part 382, and the control pin 322 is electrically connected with the control terminal 348, and is used for outputting a control signal It is used to control the electrical connection between the control end 348 and the first connection end 344 or the second connection end 346 .

The detection pin 324 is used to obtain whether the SIM card is inserted into the electronic device 1 through the detection part 382 , and the control pin 322 is used to control the switch 340 . The level of the detection part 382 can quickly control the switching of the switch 340. For example, when the electronic device 1 is powered on, the control terminal 348 of the switch 340 can quickly select a SIM card or an eSIM card according to the level of the detection part 382, and the electronic device 1 is started up. After that, the radio frequency chip 320 can receive the mobile signal according to the SIM card or eSIM card selected by the switch 340. If the SIM card is invalid, the radio frequency chip 320 can also control the switch 340 to switch through the control pin 322, so as to connect with the radio frequency chip 320. Switch your SIM card to an eSIM.

Please refer to FIG. 6 and FIG. 7 , FIG. 6 is a schematic structural diagram of a card holder in an electronic device according to an embodiment of the present application, and FIG. 7 is an exploded schematic diagram of the card holder shown in FIG. 6 . The card holder 380 includes the connector 140 and the detection elastic piece 160, and the detection elastic piece 160 can be used as the detection part in the above-mentioned embodiment. When the plug-in customer identification card is not inserted into the socket 380, the detection elastic piece 160 is electrically connected with the connector 140, so that the level of the detection elastic piece 160 is the first level; when the plug-in customer identification card is inserted into the socket 380, the detection The elastic piece 160 is separated from the connecting member 140, so that the level of the detection elastic piece 160 is the second level. By detecting the physical connection between the dome 160 and the connector 140, the level of the detecting dome 160 is changed. Even if the SIM card is not inserted into the card holder 380 or the SIM card is invalid, the detection of the detecting dome 160 will not be affected, and whether the SIM card is detected can be accurately detected. Inserting the card holder 380 improves the accuracy of the SIM card detection by the card holder 380 .

Please continue to refer to FIG. 6 and FIG. 7 , the card holder 380 may further include a bracket 120 , and both the connector 140 and the detection elastic piece 160 are disposed on the bracket 120 . When the SIM card is not inserted into the card holder 380 , the detection elastic piece 160 is electrically connected to the connector 140 . , when the SIM card is inserted into the card holder 380, the detection elastic piece 160 and the connecting piece 140 are arranged at intervals. Whether a SIM card is inserted into the card holder 380 can be determined by detecting the connection state between the elastic piece 160 and the connector 140 . The detection of the physical contact and separation of the elastic piece 160 and the connector 140 can accurately obtain whether the SIM card is inserted into the card holder 380 , thereby improving the accuracy of detecting whether the SIM card is inserted into the card holder 380 .

It should be noted that, in the related art, the card holder is provided with a detection circuit connected to the SIM card. When the SIM card is not inserted into the card holder, the detection circuit is disconnected. When the SIM card is inserted into the card holder, the detection circuit is electrically connected to the SIM card. Thus, a loop is formed, and it is further detected that the SIM card is inserted into the card holder. However, if the SIM card is not inserted into the card holder or the SIM card is invalid, it cannot be effectively detected.

In this embodiment, whether a SIM card is inserted into the card holder 380 is detected by detecting the physical connection between the elastic sheet 160 and the connector 140 . When the SIM card is not inserted into the card holder 380, the detection elastic piece 160 abuts against the connector 140 to realize electrical connection. When the SIM card is inserted into the card holder 380, the detection elastic piece 160 is squeezed by the SIM card to separate it from the connector 140, so that the detection The elastic piece 160 is arranged at intervals from the connecting piece 140 , and the detection level of the elastic piece 160 is no longer affected by the connecting piece 140 . For example, when the SIM card is not inserted into the card holder 380, the detection spring 160 is electrically connected to the connector 140, and the connector 140 will affect the level of the detection spring 160. For example, if the level of the detection spring 160 is low, when the SIM card When the card holder 380 is inserted, the detection spring 160 is squeezed by the SIM card to separate it from the connector 140, the level of the detection spring 160 is no longer pulled down by the connector 140, and the detection spring 160 changes from a low level to a high level. Therefore, it is possible to identify whether a SIM card is inserted by detecting the level change of the dome 160, and the level change of the detection dome 160 is determined by detecting the physical connection or physical separation of the dome 160 and the connector 140, even if the SIM card is inserted into the card holder 380 without Whether the SIM card is in place or the SIM card is invalid will not affect the detection of the detection spring 160 , and can accurately detect whether the SIM card is inserted into the card holder 380 .

Please refer to Figure 8, Figure 9 and Figure 10. Figure 8 is a schematic diagram of the structure of the bracket, the connector and the detection spring in the card holder shown in Figure 7, Figure 9 is an enlarged schematic diagram of part A in the structure shown in Figure 8, and Figure 10 is Figure 7 is a schematic structural diagram of the connector in the card holder. The connecting member 140 may include a connecting portion 142 and a blocking portion 144. The connecting portion 142 is connected to the bracket 120.
