An electronic apparatus 100 and a control method thereof according to an embodiment of the present application are described below with reference to fig. 1 to 9.

< electronic apparatus 100>

As shown in fig. 7 to 8, an electronic apparatus 100 according to some embodiments of the present application includes a socket 11, a functional device 16, and a selection device.

The card holder 11 is provided with a first pin and a second pin.

The functional device 16 is provided with a third pin.

The selection device is used for switching the connection of the third pin and the first pin or the second pin.

The switching device responds to a first signal to connect the first pin and the third pin under the condition that the pin of the function card is in contact with the first pin;

the switching device responds to a second signal to connect the second pin and the third pin under the condition that the pin of the function card is in contact with the second pin.

Specifically, the electronic device 100 may be, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a game console, an intercom, a display, a telephone, a Virtual Reality device (VR), an Augmented Reality device (AR), and the like.

As shown in fig. 7, the electronic device 100 includes a housing. A card holder 11, a functional device 16, a first processor 12 and a selection means are provided in the housing. The opening of the card holder 11 is located on the side of the housing. The function card is inserted into the card holder 11 from the opening.

The selection device includes a first circuit, a second circuit, and a switching device. The switching device is connected to the first processor 12, and the first processor 12 is configured to send a control signal, such as a first signal and a second signal, to the selection device. Of course, the control signal may be sent by other devices, such as a mobile terminal. The switching device is used for switching the first circuit and the second circuit to work so as to connect the third pin with the first pin or the second pin.

The function Card may be, but is not limited to, a Subscriber Identity Module (SIM) Card, a Secure Digital Memory Card (SD Card), and the like.

The functional device 16 is an electronic apparatus 100 that implements a setting function within the electronic apparatus 100, and is, for example, a speaker, a display, a power supply 13, a processor, a microphone, a receiver, a signal transmitting apparatus, a signal receiving apparatus, or the like.

The third pin may be, but is not limited to, any one of an input-output (In-OUT, IO) pin, a Clock (Clock, CLK) pin, a program Voltage (VPP) pin, a RESET (RESET) pin, a Ground (GND) pin, and a power supply (VCC) pin. The kind and number of the third pins can be selected by those skilled in the art according to actual needs.

Optionally, the card socket 11 may be provided with one first pin and one second pin, or a plurality of first pins and a plurality of second pins, so as to adapt to the connection requirements of different function cards. The functional device 16 may be provided with one or more third pins. The number and function of the third pins are matched with those of the function card.

If the functional device 16 has two third pins, the function card should also have two pins.

Accordingly, when the first pin is connected to one of the third pins, the second pin should be connected to the other third pin, and in this condition, the first pin and the second pin are multiplexed.

Alternatively, the number of the first pins may be two, and the two third pins may be in one-to-one correspondence with the two first pins and connected, and under this condition, the first pins and the second pins are not multiplexed.

Of course, the card holder 11 may be provided with more first pins and second pins. The functional device 16 may also be provided with more third pins.

In a specific example, the first pin and the second pin are adapted to a setting pin of a function card to communicatively connect the function card to the electronic device 100. As shown in fig. 7, the first pins and the second pins are symmetrically arranged, so that when the function card is inserted along the first direction, the first pins are matched with the pins set by the function card; as shown in fig. 8, when the function card is inserted in the second direction, the second pin is matched with the set pin. Wherein the second direction is opposite to the first direction.

Here, the first pin and the second pin are symmetrically disposed with respect to a set point or line, or the first pin and the second pin are asymmetric.

The symmetric arrangement means, for example, that the first pin and the second pin are symmetric with respect to the center of the surface where the pin of the function card is located under the condition that the function card is inserted into the socket 11, or are symmetric with respect to the center position of the card insertion direction of the socket 11, as long as the first pin or the second pin is connected to the set third pin when the function card is inserted in two opposite directions.

The first processor 12 is configured to send a control signal when the function card is inserted into the card socket 11, so as to control the conduction of the setting circuit of the selection device, so that the first pin or the second pin is adapted to the setting pin of the function card. The first processor 12 may be a separately provided processor for controlling the selection means; the processor of the electronic device 100 may be provided with the above-described functions by software.

The selection means is capable of enabling the third pin to be connected to the first pin or to the second pin in response to a signal from the first processor 12. The selector may be an independent two-way data selector, or may be a Programmable logic Array (FPGA).

According to the electronic device 100 of the embodiment of the application, the socket 11 is provided with the first pin and the second pin. When the function card is inserted along the first direction or the second direction, the first pin or the second pin can be matched with the corresponding pin on the function card. The third pin of the functional device 16 is connected to the first pin or the second pin through a switching device. Wherein the first direction is different from the second direction.

Under the condition that the function card is inserted into the card seat 11, the switching device responds to the first signal to connect the first pin (for example, through a first circuit) with the third pin so as to adapt to the setting pin of the function card; or a second signal responsive to which the switching device is responsive to connect the second pin (e.g., via a second circuit) with the third pin to thereby adapt the set pin of the function card.

In this way, the connection of the functional device 16 with the functional card can be achieved regardless of whether the functional card is inserted in the first direction or the second direction into the card holder 11. When the user inserts the function card, the user does not need to identify the placement direction of the function card, thereby facilitating the card insertion operation.

For example, all pins of the function card are located on the same surface. In one case, when the function card is inserted into the card holder 11 in the first direction or the second direction, the pins face the same side, as shown in fig. 7 to 8. In this way, the number of pins included in the socket 11 may be an odd number or an even number. When the pins of the socket are odd in number and the first pin and the second pin are both multiple, if one of the first pin and the second pin (for example, the first pin) is connected with the third pin, at least part of the other pin (for example, part of the second pin) is idle. In the case of an even number, when one of the first pin and the second pin is connected to the third pin, the other pin may be connected to the other pin of the functional device 16. The first pin and the second pin may not be multiplexed or may be at least partially multiplexed.

For example, as shown in fig. 9, the number of the first pins (e.g., a, b, c, d, e, f in fig. 9) is the same as the number of the third pins of the functional device 16. The number of second pins (e.g., a1, b1, c1, d1, e1, f1 in fig. 9) is the same as the number of third pins of the functional device 16. The number of the third pins is even. The first pin and the second pin are centrosymmetric with respect to the center of the socket 11. In the first state, the third pin of the functional device 16 is connected to the first pin. In the case where the SD card 23 is inserted into the card holder in the direction shown in fig. 9, the pins of the SD card 23 are fitted with the first pins, as indicated by S in fig. 9. In the case where the SD card 23 is inserted into the card holder in the direction opposite to the direction shown in fig. 9, the pin of the SD card 23 is fitted with the second pin, as shown by S' in fig. 9. In this example, the first pin and the second pin are not multiplexed. Of course, in other examples, the first pin and the second pin may also be partially or fully multiplexed.

In another case, the function card is inserted in a first direction or a second direction with the pins facing different sides. Thus, the first pin is located at one side of the jack of the socket 11, and the second pin is located at the opposite side of the jack of the socket 11. The socket 11 includes the number of pins whether in an odd number or an even number. When one of the first pin and the second pin is connected to the third pin, the other of the first pin and the second pin is idle.

In some embodiments, the first processor 12 further includes a fourth pin. Optionally, the fourth pin is any one of an IO pin, a CLK pin, a VPP pin, a RESET pin, a GND pin, and a VCC pin. The third pin and the fourth pin have different functions.

The switching device is also responsive to the first signal to connect the second pin with the fourth pin on the condition that the pin of the function card is in contact with the first pin and in contact with the second pin; alternatively, the first and second electrodes may be,

the switching device is also responsive to the second signal to connect the first pin with the fourth pin.

That is, in this example, the switching device is responsive to a first signal from the first processor 12 to connect the first pin (e.g., via the first circuit) to the third pin and the second pin to the fourth pin via the first circuit.

Alternatively, the switching device is responsive to a second signal from the first processor 12 to connect the second pin (e.g., via the second circuit) to the third pin and the first pin to the fourth pin via the second circuit.

In this way, the first pin and the second pin on the card socket 11 can be switched to connect with the third pin and the fourth pin of the function device through the switching device, so that when the function card is inserted into the card socket 11 along different directions, the first pin and the second pin are respectively matched with different function pins of the function card, thereby realizing multiplexing of the first pin and the second pin.

In some embodiments, as shown in fig. 1, the selection means comprises a first selector and a second selector. The first selector comprises a first switch, a second switch and a first switcher, the first pin can be connected with the third pin through the first switch, the second pin can be connected with the third pin through the second switch, and the first switcher is used for switching the first switch and the second switch to work.

The second selector comprises a third switch, a fourth switch and a second switcher, the second pin can be connected with the fourth pin through the third switch, the first pin can be connected with the fourth pin through the fourth switch, and the second switcher is used for switching the third switch and the fourth switch to work.

In this example, the first circuit includes the first switch and the third switch, the second circuit includes the second switch and the fourth switch, and the switching device includes the first switch and the second switch.

In this example, the switching means is responsive to a first signal to cause the first switch and the third switch to close and the second switch and the fourth switch to open under a condition that the pin of the function card is in contact with the first pin, thereby causing the first pin to be connected with the third pin and the second pin to be connected with the fourth pin.

Under the condition that the pin of the function card is in contact with the second pin, the switching device responds to a second signal to enable the second switch and the fourth switch to be switched on, and the first switch and the third switch are switched off, so that the second pin is connected with the third pin, and the first pin is connected with the fourth pin.

The first selector and the second selector are independent two-way data selectors. The selector has simple structure, easy control and high precision.

In other embodiments, as shown in FIG. 3, the selection means comprises a first selector and a second selector.

The first selector comprises a first switch, a second switch and a first switcher, the first pin can be connected with the third pin through the first switch, the first pin can be connected with the fourth pin through the second switch, and the first switcher is used for switching the first switch and the second switch to work.

The second selector comprises a third switch, a fourth switch and a second switcher, the second pin can be connected with the fourth pin through the third switch, the second pin can be connected with the third pin through the third switch, and the second switcher is used for switching the third switch and the fourth switch to work.

In this example, the first circuit includes the first switch and the third switch, the second circuit includes the third switch and the fourth switch, and the switching device includes the first switch and the second switch.

In this example, in the first state, the switching device is responsive to the first signal to cause the first switch and the third switch to close and the second switch and the fourth switch to open such that the first pin is connected to the third pin and the second pin is connected to the fourth pin.

In a second state, the switching device is responsive to a second signal to close the second switch and the fourth switch, and the first switch and the third switch are open, thereby connecting the second pin to the third pin and the first pin to the fourth pin.

The two switching devices adopt the switch to control the connection and disconnection of the first circuit and the second circuit, and the switch has the advantages of simple structure, easy control and high control precision.

Further, the first switch and the second switch constitute a single-pole double-throw switch, and the third switch and the fourth switch constitute a single-pole double-throw switch. The single pole double throw switch is simpler in construction and when one switch is closed, the other switch is automatically opened, which makes switching between the first circuit and the second circuit easier.

In one example, the first signal is a high level signal and the second signal is a low level signal; or the first signal is a low level signal and the second signal is a high level signal.

Of course, the first signal and the second signal may be at least one of a current signal, an inductive signal, a resistive signal, and a capacitive signal. The skilled person can select the desired one according to the actual need.

In one example, the functional device 16 comprises a first processor 12 of the electronic device; or the functional device 16 comprises a power supply 13 of the electronic equipment and a second processor 12 'of the electronic equipment, and the power supply 13 and the second processor 12' are respectively provided with the third pin.

Of course, as mentioned above, the functional device 16 may also be a speaker, a display, etc. The skilled person can select the desired one according to the actual need.

< control method >

According to another embodiment of the present application, there is provided a control method of the electronic apparatus 100 described above. The control method comprises the following steps:

the switching device responds to a first signal to connect the first pin with the third pin under the condition that a function card is inserted into the socket 11 and the pin of the function card is in contact with the first pin;

the switching means is responsive to a second signal to connect the second pin with the third pin on the condition that a function card is inserted into the socket 11 and the pin of the function card is in contact with the second pin.

In the embodiment of the present application, through the above-mentioned control method, the electronic device 100 can automatically adjust the connection relationship between the first pin and the second pin in the socket 11 and the third pin of the function device 16, so that the first pin and/or the second pin are/is adapted to the pin of the function card. In this way, a connection with the functional device 16 can be made whether the functional card is inserted into the socket 11 in the first orientation or the socket 11 in the second orientation.

In one example, the control method further comprises: and under the condition that the switching device respectively responds to the first signal and the second signal and the function card is not identified successfully, judging that the function card is damaged.

If not successful, the first processor 12 issues a second signal, e.g., a low level signal.

The switching means is responsive to the second signal so that the first switches of selector No. 1 14, selector No. 2 17 and selector No. 3 19 are closed, and the second switches of selector No. 1 14, selector No. 2 17 and selector No. 3 19 are open; the third switches of the selector No. 4, selector No. 5, and selector No. 6, 20 are turned off, and the fourth switches of the selector No. 4, selector No. 5, 18, and selector No. 6, 15 are turned on. In this state, the IO pin is connected to the a pin, the CLK pin is connected to the d pin, the VPP pin is connected to the b pin, the RESET pin is connected to the e pin, the GND pin is connected to the c pin, and the VCC pin is connected to the f pin.

Next, the first processor 12 identifies the SIM card 22 and determines whether the SIM card 22 is successfully identified.

If successful, the control process ends.

If not, it is determined that the SIM card 22 has been tampered with and a third signal is sent to indicate that the SIM card 22 has been tampered with.

The pins and the connection relationship are not limited in the present application, and the above embodiments are only examples for convenience of description, and those skilled in the art can select the types and connection relationships of the pins and the selectors according to actual needs.
