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 holder 380 has a 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 maintain the current on state until the electronic device 1 is restarted.

The rf chip 320 is configured to control the fixed connection terminal 342 to be connected to the first connection terminal 344 or the second connection terminal 346, specifically, if the card holder 380 has no subscriber identification card, the rf chip 320 controls the fixed connection terminal 342 to be connected to the first connection terminal 344, and if the card holder 380 has a subscriber identification card, the rf chip 320 controls the fixed connection terminal 342 to be connected to the second connection terminal 346. 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 maintain the current on state until the electronic device 1 is restarted.

Illustratively, the RF chip 320 includes a sense pin 322, the cartridge 380 includes a sense portion 382, and the sense pin 322 is electrically coupled to the sense portion 382. When the detection pin 322 of the radio frequency chip 320 detects that the level of the detection portion 382 is the first level, the radio frequency chip 320 determines that the card holder 380 has no customer identification card; when the detection pin 322 of the rf chip 320 detects that the level of the detection portion 382 is the second level, the rf chip 320 determines that the card holder 380 has the subscriber identity 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 in the card holder 380 according to the level of the detecting portion 382, the control pin 324 controls the fixed connection terminal 342 of the switch 340 to connect with the first connection terminal 344 or the second connection terminal 346.

Referring to fig. 4, fig. 4 is a schematic diagram of a fourth structure of an electronic device according to an embodiment of the present application.

Control terminal 348 of switch 340 is electrically connected to cartridge 380, and there is a different signal as to whether or not there is a customer identification card in cartridge 380. For example, if there is no SIM card in the card holder 380, the detection portion 382 of the card holder 380 is at a low level, and if there is a SIM card in the card holder 380, the detection portion 382 of the card holder 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 portion 382 of the cartridge 380. For example, the low level of the detecting portion 382 may enable the control terminal 348 to control the fixed connection terminal 342 to be connected with the first connection terminal 344, i.e. to enable the rf chip 320 to be connected with the eSIM card, and the high level of the detecting portion 382 may enable the control terminal 348 to control the fixed connection terminal 342 to be connected with the second connection terminal 346, i.e. to enable the rf chip 320 to be connected with the SIM card. The card holder 380 can quickly control the switch 340 to switch through the level change, and the switching speed is high.

Referring to fig. 6 and fig. 7, fig. 6 is a sixth structural schematic diagram of an electronic device according to an embodiment of the present application, and fig. 7 is a seventh structural schematic diagram of an electronic device according to an embodiment of the present application.

Wherein the disconnection of control 348 from cartridge 380 may be accomplished by a selection switch unit within switch 340 or by another switch separate from switch 340. The disconnection of the control terminal 348 from the card holder 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 holder 380, and after the control end 348 controls the fixed connection end 342 to be connected to the first connection end 344 or the second connection end 346 according to whether the card holder 380 has a customer identification card, the control end 348 is disconnected from the card holder 380 until the electronic device 1 is restarted.

The RF chip 320 is electrically connected to the control terminal 348; when the electronic device 1 is powered on, the rf chip 320 controls the control terminal 348 to be electrically connected to the card holder 380. After the control end 348 controls the fixed connection end 342 to be connected with the first connection end 344 or the second connection end 346, the radio frequency chip 320 controls the control end 348 to be disconnected with the card holder 380.

When the electronic device 1 is powered on and started, the radio frequency chip 320 controls the control end 348 of the switch 340 to be electrically connected with the card holder 380, the control end 348 of the switch 340 selects the first connection end 344 or the second connection end 346 to be conducted with the fixed connection end 342 according to the level of the card holder 380, and then the radio frequency chip 320 disconnects the control end 348 from the card holder 380, so that the fixed connection end 342 is fixedly connected with the first connection end 344 or the second connection end 346, and before the electronic device 1 is not powered off, the radio frequency chip 320 is fixedly connected with the SIM card or the eSIM card.

It will be appreciated 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, a control instruction of another device such as a mobile phone, to control the switch 340 to switch. Such as switching the second connection 346 to the fixed connection 342 to the first connection 344, i.e., switching the eSIM card to the SIM card. In other embodiments, the switch 340 may also be controlled by a toggle button of the electronic device 1.

Referring to fig. 9, fig. 9 is a schematic diagram 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 power first output terminal 345 and a power second output terminal 347, the power input terminal 343 is electrically connected with the power management circuit 350, the power first output terminal 345 is electrically connected with the embedded client identification card 360, the power second output terminal 347 is electrically connected with the card holder 380, if there is no client identification card in the card holder 380, the power input terminal 343 is conducted with the power first output terminal 345, and if there is a client identification card in the card holder 380, the power input terminal 343 is conducted with the power second output terminal 347. The non-working SIM card or 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 mutual interference is reduced.

Referring to fig. 10 and 11, fig. 10 is a schematic structural diagram of a card holder in an electronic device according to an embodiment of the present application, and fig. 11 is an exploded schematic diagram of the card holder shown in fig. 10. The card holder 380 may further include a bracket 120, a connecting piece 140 and a detecting elastic piece 160, where the connecting piece 140 and the detecting elastic piece 160 are both disposed on the bracket 120, and when the SIM card is not inserted into the card holder 380, the detecting elastic piece 160 is electrically connected to the connecting piece 140, and when the SIM card is inserted into the card holder 380, the detecting elastic piece 160 is disposed at intervals with the connecting piece 140. By detecting the connection state of the spring 160 and the connector 140, it can be determined whether a SIM card is inserted into the card holder 380. The detection spring 160 and the connecting piece 140 are physically abutted and separated, so that whether the SIM card is inserted into the card holder 380 can be accurately obtained, and the accuracy of detecting whether the SIM card is inserted into the card holder 380 is improved.

It should be noted that, in the related art, a detection circuit connected with the SIM card is disposed in the card holder, when the SIM card is not inserted into the card holder, the detection circuit is opened, and when the SIM card is inserted into the card holder, the detection circuit is electrically connected with the SIM card to form a loop, so as to detect that the SIM card is inserted into the card holder. However, if the SIM card is not inserted into the card holder 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 holder 380 by detecting the physical connection between the spring 160 and the connector 140. When the SIM card is not inserted into the card holder 380, the detecting spring 160 abuts against the connecting piece 140 to implement electrical connection, and when the SIM card is inserted into the card holder 380, the detecting spring 160 is pressed by the SIM card to separate from the connecting piece 140, so that the detecting spring 160 and the connecting piece 140 are arranged at intervals, and the level of the detecting spring 160 is not affected by the connecting piece 140. For example, when the SIM card is not inserted into the card holder 380, the detecting spring 160 is electrically connected to the connecting member 140, where the connecting member 140 affects the level of the detecting spring 160, for example, the level of the detecting spring 160 is low, when the SIM card is inserted into the card holder 380, the detecting spring 160 is pressed by the SIM card to separate from the connecting member 140, the level of the detecting spring 160 is no longer pulled down by the connecting member 140, and the detecting spring 160 changes from low level to high level, so that whether the SIM card is inserted or not can be determined by the level change identification of the detecting spring 160, and the level change of the detecting spring 160 is determined by the physical connection or physical separation of the detecting spring 160 and the connecting member 140, so that even if the SIM card is not inserted into the card holder 380 or the SIM card is invalid, the detection of the detecting spring 160 is not affected, and whether the SIM card is inserted into the card holder 380 can be accurately detected.

Referring to fig. 12, 13 and 14, fig. 12 is a schematic structural view of a bracket, a connector and a detecting spring in the cartridge 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 connector in the cartridge shown in fig. 11. The connecting piece 140 may include a connecting portion 142 and a blocking portion 144, where the connecting portion 142 is connected to the bracket 120, the connecting portion 142 is spaced from the detecting spring 160, the blocking portion 144 protrudes from the connecting portion 142 toward the detecting spring 160, and when the plug-in customer identification card is not inserted into the card holder 380, the detecting spring 160 abuts against the blocking portion 144, and when the plug-in customer identification card is inserted into the card holder 380, the detecting spring 160 is separated from the blocking portion 144. The blocking portion 144 protruding from the connection portion 142 can block the detection spring 160, 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 holder 380, the blocking portion 144 abuts against the detecting elastic piece 160 and makes the detecting elastic piece 160 have a certain elastic deformation, so that the detecting elastic piece 160 abuts against the blocking portion 144 tightly, and the stability of the electrical connection between the detecting elastic piece 160 and the blocking portion 144 is ensured. When the plug-in type subscriber identity card is inserted into the card holder 380, the plug-in type subscriber identity card presses the elastic spring sheet, and the elastic spring sheet can be separated from the blocking portion 144 and spaced apart from the connection member 140 by conveniently pressing the blocking portion 144 apart from the connection portion 142 according to an external force because the blocking portion 144 protrudes from the connection portion 142.
