Card socket 380 is used to receive plug-in subscriber identity card 400(SIM card), and card socket 380 is electrically connected to second connection terminal 346. The rf chip 320 is electrically connected to the fixed connection 342.

When the electronic device 1 is powered on and started, if the card socket 380 does not have the plug-in type sim card 400, the fixed connection end 342 is connected to the first connection end 344, and if the card socket 380 has the plug-in type sim card 400, the fixed connection end 342 is connected to the second connection end 346. When the fixed connection terminal 342 is turned on with the first connection terminal 344 or the second connection terminal 346 according to whether the card socket 380 has the plug-in type subscriber identity module 400 therein, the switch 340 maintains the current on state until the electronic apparatus 1 is restarted.

The radio frequency chip 320 can be selectively connected with the embedded customer identification card 360 or the plug-in customer identification card 400 in the card seat 380 through the switch 340, and can be switched between the embedded customer identification card 360 or the plug-in customer identification card 400 only by controlling the switching of the switch 340 without switching through complex technical means, thereby improving the convenience of switching the embedded customer identification card 360 and the plug-in customer identification card 400. Moreover, only when the electronic device 1 is powered on and started, the SIM card or the eSIM card connected to the radio frequency chip 320 is selected according to whether the SIM card exists in the card socket 380, and after the circuit structure is started, the switch 340 maintains the current state until the electronic device 1 is restarted.

It is understood that an embedded subscriber identity module card (eSIM card) is a chip fixed in an electronic device, and a plug-in subscriber identity module card (SIM card) is removably installed in the electronic device.

When the electronic device 1 is powered on and started, the radio frequency chip 320 controls the fixed connection end 342 to be conducted with the first connection end 344 or the second connection end 346 according to whether the card socket 380 has the customer identification card; after the rf chip 320 controls the fixed connection terminal 342 to be connected to the first connection terminal 344 or the second connection terminal 346, the rf chip 320 controls the switch 340 to keep the current connection state until the electronic device 1 is restarted.

The rf chip 320 is configured to control the fixed connection end 342 to be conducted with the first connection end 344 or the second connection end 346, specifically, if the card socket 380 does not have a customer id card, the rf chip 320 controls the fixed connection end 342 to be conducted with the first connection end 344, and if the card socket 380 has a customer id card, the rf chip 320 controls the fixed connection end 342 to be conducted with the second connection end 346. After the radio frequency chip 320 controls the fixed connection terminal 342 to be conducted with the first connection terminal 344 or the second connection terminal 346, the radio frequency chip 320 controls the switch 340 to keep the current conduction state until the electronic device 1 is restarted.

Illustratively, the rf chip 320 includes a detection pin 322, the socket 380 includes a detection portion 382, and the detection pin 322 is electrically connected to the detection portion 382. When the detection pin 322 of the rf chip 320 detects that the level of the detection part 382 is the first level, the rf chip 320 determines that the card socket 380 does not have the customer id card; when the detection pin 322 of the rf chip 320 detects that the level of the detection part 382 is a second level, the rf chip 320 determines that the card socket 380 has the customer id card therein, and the second level is different from the first level.

The rf chip 320 may further include a control pin 324, and after the rf chip 320 determines whether the SIM card is present in the card socket 380 according to the level of the detection part 382, the fixed connection terminal 342 of the switch 340 is controlled to be connected to the first connection terminal 344 or the second connection terminal 346 through the control pin 324.

Referring to fig. 4, fig. 4 is a schematic view illustrating a fourth structure of an electronic device according to an embodiment of the present disclosure. The electronic device 1 may further include a switch controller 330, an input terminal of the switch controller 330 is electrically connected to the card socket 380, an output terminal of the switch controller 330 is electrically connected to the switch 340, and the switch controller 330 controls the switch 340 according to whether the card socket 380 has the customer id card therein.

The switch 340 may be controlled by a switch controller 330 in the electronic device 1, the switch controller 330 may be a processor or other chip, and the processor may be electrically connected to the card socket 380 and obtain whether the card socket 380 has a SIM card. The switch 340 is then controlled according to whether the SIM card is present in the card socket 380, so that the SIM card or the eSIM card is electrically connected to the rf chip 320.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a fifth electronic device according to an embodiment of the present disclosure. The switch 340 includes a control terminal 348, the control terminal 348 is electrically connected to the card socket 380, and the control terminal 348 controls the connection of the fixed connection terminal 342 and the first connection terminal 344 or the second connection terminal 346 according to whether the card socket 380 has the sim card therein.

Control terminal 348 of switch 340 is electrically connected to card socket 380, and whether card socket 380 has a customer identification card or not may be signaled differently. For example, if the SIM card is not present in the card socket 380, the detection unit 382 of the card socket 380 is at a low level, and if the SIM card is present in the card socket 380, the detection unit 382 of the card socket 380 is at a high level. The control terminal 348 of the switch 340 is controlled according to the high level or the low level of the detection unit 382 of the card socket 380. For example, the low level of the detection part 382 may enable the control terminal 348 to control the fixed connection terminal 342 to be conducted with the first connection terminal 344, i.e., enable the rf chip 320 to be connected with the eSIM card, and the high level of the detection part 382 may enable the control terminal 348 to control the fixed connection terminal 342 to be conducted with the second connection terminal 346, i.e., enable the rf chip 320 to be connected with the SIM card. The card socket 380 can rapidly control the switch 340 to switch through the level change, and the switching speed is high.

Referring to fig. 6 and 7, fig. 6 is a sixth schematic structural diagram of an electronic device according to an embodiment of the present application, and fig. 7 is a seventh schematic structural diagram of the electronic device according to the embodiment of the present application. After the control end 348 controls the connection between the fixed connection end 342 and the first connection end 344 or the second connection end 346 according to whether the sim card socket 380 has a sim card, the control end 348 is disconnected from the card socket 380.

After the control end 348 of the switch 340 controls the fixed connection end 342 to be connected with the first connection end 344 or the second connection end 346 according to whether the SIM card is in the card socket 380, the control end 348 may be disconnected from the card socket 380, and the switch 340 is no longer influenced by the card socket 380. Wherein, the disconnection between the control terminal 348 and the card socket 380 can be realized by a selection switch unit in the switch 340 or another independent switch outside the switch 340. The disconnection between the control terminal 348 and the card socket 380 may be controlled by a functional component inside the switch, or may be controlled by other functional components outside the switch, such as a radio frequency chip or a processor.

When the electronic device 1 is powered on and started, the control end 348 is electrically connected to the card socket 380, and after the control end 348 controls the connection between the fixed connection end 342 and the first connection end 344 or the second connection end 346 according to whether the card socket 380 has the sim card therein, the control end 348 is disconnected from the card socket 380 until the electronic device 1 is restarted.

When the electronic device 1 is powered on and started, the control terminal 348 of the switch 340 is electrically connected to the card socket 380, the control terminal 348 of the switch 340 selects the first connection terminal 344 or the second connection terminal 346 to be electrically connected to the fixed connection terminal 342 according to the level of the card socket 380, and then the radio frequency chip 320 or the switch 340 or other functional elements disconnect the control terminal 348 from the card socket 380, so that the fixed connection terminal 342 is fixedly connected to the first connection terminal 344 or the second connection terminal 346, and before the electronic device 1 is not powered off, the radio frequency chip 320 is fixedly connected to a SIM card or an eSIM card. When the electronic device 1 is restarted, the control terminal 348 of the switch 340 is electrically connected to the card socket 380 by default, and the first connection terminal 344 or the second connection terminal 346 is selected to be connected to the fixed connection terminal 342 again according to whether a SIM card is present in the card socket 380.

Referring to fig. 8, fig. 8 is an eighth structural schematic diagram of an electronic device according to an embodiment of the present disclosure. The rf chip 320 is electrically connected to the control terminal 348; when the electronic device 1 is powered on and started, the rf chip 320 controls the control terminal 348 to be electrically connected to the card socket 380. After the control terminal 348 controls the fixed connection terminal 342 to be connected to the first connection terminal 344 or the second connection terminal 346, the rf chip 320 controls the control terminal 348 to be disconnected from the card socket 380.

When the electronic device 1 is powered on and started, the control terminal 348 of the radio frequency chip 320 control switch 340 is electrically connected to the card socket 380, the control terminal 348 of the switch 340 selects the first connection terminal 344 or the second connection terminal 346 to be connected to the fixed connection terminal 342 according to the level of the card socket 380, then the radio frequency chip 320 disconnects the control terminal 348 from the card socket 380, so that the fixed connection terminal 342 is fixedly connected to the first connection terminal 344 or the second connection terminal 346, and before the electronic device 1 is powered off, the radio frequency chip 320 is fixedly connected to a SIM card or an eSIM card. When the electronic device 1 is restarted, the control terminal 348 of the control switch 340 of the rf chip 320 is electrically connected to the card socket 380, and the first connection terminal 344 or the second connection terminal 346 is selected to be electrically connected to the fixed connection terminal 342 again according to whether a SIM card is present in the card socket 380.

It is understood that before the electronic device 1 is not turned off, the functional unit, such as the rf chip 320 or the processor, of the electronic device 1 may receive a switching instruction, for example, receive a control instruction of another device, such as a mobile phone, to control the switch 340 to switch. If the second connection end 346 connected to the fixed connection end 342 is switched to the first connection end 344, the eSIM card connected to the rf chip 320 is switched to a SIM card. In other embodiments, the switch 340 can be controlled by a switch button of the electronic device 1.

Referring to fig. 9, fig. 9 is a schematic view of a ninth structure of an electronic device according to an embodiment of the present application. The electronic device 1 further includes a power management circuit 350, the switch 340 further includes a power input terminal 343, a first power output terminal 345, and a second power output terminal 347, the power input terminal 343 is electrically connected to the power management circuit 350, the first power output terminal 345 is electrically connected to the embedded sim card 360, the second power output terminal 347 is electrically connected to the card socket 380, if no sim card is present in the card socket 380, the power input terminal 343 is electrically connected to the first power output terminal 345, and if a sim card is present in the card socket 380, the power input terminal 343 is electrically connected to the second power output terminal 347. The non-working SIM card or the eSIM card does not need to be supplied with power, and the SIM card circuit and the eSIM card circuit are mutually isolated, so that the mutual interference is reduced.

Referring to fig. 10 and fig. 11, fig. 10 is a schematic structural diagram of a card socket in an electronic device according to an embodiment of the present disclosure, and fig. 11 is an exploded schematic diagram of the card socket shown in fig. 10. The card socket 380 may further include a support 120, a connecting member 140 and a detecting elastic sheet 160, wherein the connecting member 140 and the detecting elastic sheet 160 are disposed on the support 120, when the SIM card is not inserted into the card socket 380, the detecting elastic sheet 160 is electrically connected to the connecting member 140, and when the SIM card is inserted into the card socket 380, the detecting elastic sheet 160 and the connecting member 140 are disposed at an interval. Whether a SIM card is inserted into the card socket 380 can be determined by detecting the connection state of the elastic sheet 160 and the connecting member 140. Whether the SIM card is inserted into the card seat 380 or not can be accurately obtained by physically abutting and separating the detection elastic sheet 160 and the connecting piece 140, so that the accuracy of detecting whether the SIM card is inserted into the card seat 380 or not is improved.

It should be noted that, in the related art, a detection circuit connected to the SIM card is disposed in the card socket, when the SIM card is not inserted into the card socket, the detection circuit is open-circuited, and when the SIM card is inserted into the card socket, the detection circuit is electrically connected to the SIM card to form a loop, thereby detecting that the SIM card is inserted into the card socket. However, if the SIM card is not inserted into the card socket in place or the SIM card is invalid, the effective detection cannot be performed.

The present embodiment detects whether a SIM card is inserted into the card socket 380 by detecting the physical connection of the spring sheet 160 and the connecting member 140. When the SIM card is not inserted into the card socket 380, the detecting elastic sheet 160 abuts against the connecting part 140 to realize electrical connection, and when the SIM card is inserted into the card socket 380, the detecting elastic sheet 160 is pressed by the SIM card to separate from the connecting part 140, so that the detecting elastic sheet 160 and the connecting part 140 are arranged at intervals, and the level of the detecting elastic sheet 160 is not influenced by the connecting part 140 any more. For example, when the SIM card is not inserted into the card socket 380, the detecting elastic sheet 160 is electrically connected to the connecting member 140, the connecting member 140 may affect the level of the detecting elastic sheet 160, for example, the level of the detecting elastic sheet 160 is low level, when the SIM card is inserted into the card socket 380, the detecting elastic sheet 160 is pressed by the SIM card to separate from the connecting member 140, the level of the detecting elastic sheet 160 is no longer pulled down by the connecting member 140, and the detecting elastic sheet 160 changes from low level to high level, therefore, it can be determined whether the SIM card is inserted through the level change identification of the detecting elastic sheet 160, the level change of the detecting elastic sheet 160 is determined by the physical connection or physical separation of the detecting elastic sheet 160 and the connecting member 140, even if the SIM card is not inserted into the card socket 380, or the SIM card is invalid, and the detection of the SIM card is not affected by the detection of the detecting elastic sheet 160, and whether the SIM card is inserted into the card socket 380 can be accurately detected.

Referring to fig. 12, 13 and 14, fig. 12 is a schematic structural view of a bracket, a connecting member and a detecting spring in the card socket shown in fig. 11, fig. 13 is an enlarged schematic view of a portion a in the structure shown in fig. 12, and fig. 14 is a schematic structural view of the connecting member in the card socket shown in fig. 11. 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, the connecting portion 142 and the detecting spring piece 160 are spaced apart, the blocking portion 144 protrudes from the connecting portion 142 to the detecting spring piece 160, the detecting spring piece 160 abuts against the blocking portion 144 when the plug-in type subscriber identity card is not inserted into the card socket 380, and the detecting spring piece 160 is separated from the blocking portion 144 when the plug-in type subscriber identity card is inserted into the card socket 380. The detection spring 160 can be blocked by the blocking portion 144 protruding from the connection portion 142, so as to be abutted and electrically connected with the detection spring 160. It should be noted that, when the plug-in customer identification card is not inserted into the card socket 380, the blocking portion 144 abuts against the detection elastic sheet 160 and the detection elastic sheet 160 has a certain elastic deformation, so that the detection elastic sheet 160 abuts against the blocking portion 144 tightly, and the stability of the electrical connection between the detection elastic sheet 160 and the blocking portion 144 is ensured. When the plug-in type subscriber identity card is inserted into the card socket 380, the plug-in type subscriber identity card will press the elastic spring sheet, and because the blocking portion 144 protrudes from the connecting portion 142, the elastic spring sheet can conveniently press the blocking portion 144 open according to external force, so as to be separated from the blocking portion 144 and spaced apart from the connecting member 140.
