DETAILED DESCRIPTION

[0040] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. On the contrary, they are only examples of devices and methods consistent with some aspects of the utility model as detailed in the attached claims. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0041] Data is stored in a smart card. When data needs to be transmitted with an electronic device, the smart card is placed in the card holder of the electronic device. After the smart card is placed in the card holder, the contacts of the smart card contact the electrical connection part of the card holder to realize data transmission between the electronic device and the smart card. For example, the electronic device can power the smart card, reset the smart card, and perform encrypted communication with the smart card through the card holder. However, after the electronic device leaves the factory, the electrical connection part of the card holder may become loose or deformed, causing abnormal contact between the smart card and the electrical connection part, making the smart card difficult to identify. Therefore, it is necessary to perform contact detection of the smart card to determine whether the abnormal contact between the smart card and the electrical connection part is caused by the electrical connection part of the card holder.

[0042] In the related art, a contact detection method is provided, including: after disassembling the electronic device, using a multimeter to test the signal of each electrical connection part of the card holder. According to the signal of the electrical connection part, determine whether the electrical connection part is faulty, so as to determine whether the contact between the smart card and the electrical connection part is abnormal. However, due to the large workload of disassembling the electronic device, there is a problem of complex contact detection. Moreover, before disassembling the electronic device, it is necessary to pull out the smart card first, so that the phenomenon of abnormal contact between the smart card and the electrical connection part disappears. Since it is impossible to determine the fault of the electrical connection part based on the signal of the electrical connection part, it is impossible to analyze the reason why the smart card is difficult to identify, thereby reducing the reliability of contact detection.

[0043] Based on this, the present disclosure provides a card holder, and a pressure sensor is provided on the electrical connection part of the card holder, and the pressure sensor is used to detect the pressure between the smart card and the electrical connection part. Since the pressure between the smart card and the electrical connection part reflects the contact between the smart card and the electrical connection part, it is possible to determine whether the contact between the smart card and the electrical connection part is abnormal based on the pressure between the smart card and the electrical connection part, thereby reducing the complexity of contact detection. At the same time, since it is not necessary to disassemble the electronic device in the process of detecting the pressure between the smart card and the electrical connection part, the complexity of contact detection is further reduced. In addition, since the pressure between the smart card and the electrical connection part is detected when the smart card and the electrical connection part are in contact, the phenomenon of abnormal contact is avoided, thereby improving the reliability of contact detection.

[0044] An exemplary embodiment of the present disclosure provides a card holder, such as Figure 1 As shown, the card holder includes a base 10 and a pressure sensor 20. The base 10 includes an electrical connection portion 11, and the electrical connection portion 11 is used to transmit data between the smart card and the electronic device. The pressure sensor 20 is arranged on the electrical connection portion 11, and the pressure sensor 20 is used to detect the pressure between the smart card and the electrical connection portion 11.

[0045] In this embodiment, the card holder includes a base and a pressure sensor, and the pressure sensor is arranged on the electrical connection part of the base. Since the pressure between the smart card and the electrical connection part of the base is different when the smart card is in normal contact and abnormal contact, the pressure between the smart card and the electrical connection part is different. By arranging the pressure sensor on the electrical connection part, the pressure between the smart card and the electrical connection part is detected to determine whether the contact between the smart card and the electrical connection part is normal, thereby reducing the complexity of contact detection.

[0046] Exemplarily, the electrical connection portion 11 may be a pin of the base 10 .

[0047] In one embodiment, if Figure 2 As shown, the base 10 includes a plurality of electrical connection parts 11 , and a pressure sensor 20 is correspondingly arranged on each electrical connection part 11 .

[0048] In this embodiment, since the smart card generally includes multiple contacts, the base needs to include multiple electrical connection parts so that different contacts of the smart card contact the corresponding electrical connection parts to transmit data. By providing a pressure sensor corresponding to each electrical connection part, it is possible to detect whether the contact between the smart card and each electrical connection part is normal, thereby improving the reliability of contact detection.

[0049] In one embodiment, if Figure 3 As shown, the electrical connection portion 11 includes a spring 111 , a fixed end of the spring 111 is fixedly connected to the base 10 , a free end of the spring 111 is used to abut against a smart card, and the pressure sensor 20 is disposed at the free end of the spring 111 .

[0050] In this embodiment, since the fixed end of the spring sheet is used to fix the spring sheet on the base, and the free end of the spring sheet is used to abut against the smart card, the pressure applied by the smart card on the free end of the spring sheet is large. By arranging the pressure sensor at the free end of the spring sheet, the pressure detected by the pressure sensor can reliably reflect the contact between the smart card and the spring sheet, thereby improving the reliability of contact detection.

[0051] In one embodiment, the surface of the free end of the spring 111 includes adjacent first and second areas, the first area is used to abut against the smart card, the pressure sensor 20 is disposed in the second area, and the pressure sensing surface of the pressure sensor 20 is flush with the surface of the first area.

[0052] In this embodiment, by making the pressure sensing surface of the pressure sensor flush with the surface of the first area of ​​the spring, data can be transmitted after the first area abuts against the smart card without affecting the pressure sensor's detection of the pressure between the smart card and the spring, thereby improving the reliability of contact detection. At the same time, it can also prevent the problem that the pressure sensor cannot detect the pressure between the smart card and the spring when the pressure sensing surface of the pressure sensor is lower than the surface of the first area and the smart card abuts against the first area of ​​the spring, thereby improving the reliability of contact detection. And it can also prevent the problem that the smart card cannot transmit data to the electronic device when the pressure sensing surface of the pressure sensor is higher than the surface of the first area and the smart card cannot contact the first area of ​​the spring, thereby improving the reliability of data transmission.

[0053] For example, a protrusion may be provided in the first region to make the pressure sensing surface of the pressure sensor 20 flush with the surface of the first region, and a groove may be provided in the second region to make the pressure sensing surface of the pressure sensor 20 flush with the surface of the first region.

[0054] In one embodiment, if Figure 4 As shown, the spring pieces 111 are arranged in two rows, and the free ends of the two rows of spring pieces 111 face in opposite directions.

[0055] In this embodiment, since the free end of the spring sheet is used to abut against the smart card, the free end of the spring sheet is subjected to pressure from the smart card, and the smart card is also subjected to pressure from the spring sheet. By providing two rows of spring sheets and making the free ends of the two rows of spring sheets face opposite directions, the smart card is subjected to uniform force after being inserted into the card holder to avoid contact abnormality, thereby improving the reliability of the base.

[0056] In one embodiment, the smart card is a Subscriber Identity Module (SIM) card.

[0057] In this embodiment, since the user identification card needs to be inserted into the card holder of the electronic device, and the number of contacts of the user identification card is large, the number of corresponding electrical connection parts is large, and the problem of abnormal contact is prone to occur. In addition, the electronic device needs to use the user identification card to identify the user before communication can be carried out. By detecting the pressure through the pressure sensor to determine the contact between the user identification card and the electrical connection part, the cause of the abnormal contact can be quickly located so that the electronic device can communicate normally, thereby reducing the complexity of contact detection.

[0058] An exemplary embodiment of the present disclosure provides an electronic device, and the electronic device includes the card holder as described above.

[0059] In this embodiment, after the smart card is inserted into the card holder of the electronic device, the pressure between the smart card and the electrical connection part is different in the case of normal contact and abnormal contact with the electrical connection part of the card holder. By arranging a pressure sensor at the electrical connection part, the pressure between the smart card and the electrical connection part is detected to determine whether the contact between the smart card and the electrical connection part is normal, thereby reducing the complexity of contact detection. At the same time, since it is possible to determine whether the contact between the smart card and the electrical connection part is normal without disassembling the electronic device, the risks caused by disassembly and the disappearance of abnormal contact phenomena are avoided, thereby improving the reliability of contact detection.

[0060] In one embodiment, if Figure 5 As shown, the electronic device further includes a detection circuit 30. The detection circuit 30 is electrically connected to the pressure sensor 20, and the detection circuit 30 is used to determine whether the contact between the smart card and the electrical connection part 11 is normal according to the pressure detected by the pressure sensor 20.

[0061] In this embodiment, since the pressure detected by the pressure sensor is different when the smart card is in normal contact and abnormal contact with the electrical connection part, the pressure transmitted by the pressure sensor received by the detection circuit is different. After receiving the pressure transmitted by the pressure sensor, the detection circuit can determine whether the contact between the smart card and the electrical connection part is normal according to the magnitude of the pressure. By adding a detection circuit to determine whether the contact between the smart card and the electrical connection part is normal, the pressure can correspond to the contact situation for contact detection, thereby improving the reliability of contact detection.

[0062] Exemplarily, in the detection circuit 30, a pressure threshold may be set as a reference to determine whether the contact between the smart card and the electrical connection portion 11 is normal. When the pressure detected by the pressure sensor 20 is greater than the pressure threshold, the contact between the smart card and the electrical connection portion 11 is normal. When the pressure detected by the pressure sensor 20 is less than or equal to the pressure threshold, the contact between the smart card and the electrical connection portion 11 is abnormal.

[0063] Exemplarily, in addition to setting a pressure threshold as a reference, the pressure detected by the pressure sensor 20 can also be determined as a reference pressure before the smart card is inserted into the card holder. After the smart card is inserted into the card holder, it is determined whether the contact between the smart card and the electrical connection part 11 is normal based on the pressure detected by the pressure sensor 20 and the reference pressure. When the pressure detected by the pressure sensor 20 is greater than the reference pressure, the contact between the smart card and the electrical connection part 11 is normal. When the pressure detected by the pressure sensor 20 is less than or equal to the reference pressure, the contact between the smart card and the electrical connection part 11 is abnormal.

[0064] Exemplarily, when there are multiple electrical connection parts 11 and each electrical connection part 11 is provided with a pressure sensor 20, before the smart card is inserted into the card holder, the pressure detected by each pressure sensor 20 can be determined respectively. The pressure detected by each pressure sensor 20 is averaged as the reference pressure. After the smart card is inserted into the card holder, it is determined whether the contact between the smart card and the electrical connection part 11 is normal according to the pressure detected by each pressure sensor 20 and the reference pressure. When the pressure detected by each pressure sensor 20 is greater than the reference pressure, the contact between the smart card and the electrical connection part 11 is normal. When the pressure detected by at least one pressure sensor 20 is less than or equal to the reference pressure, the contact between the smart card and the electrical connection part 11 is abnormal. Alternatively, it is also possible to determine the pressure detected by each pressure sensor 20 as the respective reference pressures. After the smart card is inserted into the card holder, it is determined whether the contact between the smart card and the electrical connection part 11 is normal according to the pressure detected by each pressure sensor 20 and the corresponding reference pressure. When the pressure detected by each pressure sensor 20 is greater than the corresponding reference pressure, the contact between the smart card and the electrical connection part 11 is normal. When the pressure detected by at least one pressure sensor 20 is less than or equal to the corresponding reference pressure, the contact between the smart card and the electrical connection portion 11 is abnormal.

[0065] In one embodiment, if Figure 6 As shown, the detection circuit 30 includes a conversion circuit 31 and a processing unit 32. The first end of the conversion circuit 31 is used to be electrically connected to the power supply VCC, and the second end of the conversion circuit 31 is electrically connected to the first end of the pressure sensor 20. The processing unit 32 is electrically connected to the conversion circuit 31. The second end of the pressure sensor 20 is used to be electrically connected to the ground terminal GND.

[0066] In this embodiment, since the pressure detected by the pressure sensor is positively correlated with the resistance of the pressure sensor, it is necessary to convert the resistance of the pressure sensor into a voltage through a conversion circuit so that the processing unit can identify it. The pressure detected by the pressure sensor can be converted into a voltage through the conversion circuit, and the processing unit can determine whether the contact between the smart card and the electrical connection part is normal according to the magnitude of the voltage, thereby reducing the complexity of contact detection.

[0067] In one embodiment, if Figure 7As shown, the conversion circuit 31 includes a resistor R. A first end of the resistor R is used to be electrically connected to the power supply VCC, and a second end of the resistor R is electrically connected to a first end of the pressure sensor 20 and the processing unit 32 .

[0068] In this embodiment, due to the simple structure of the resistor, a voltage divider circuit can be formed by the resistor of the conversion circuit and the resistor of the pressure sensor, and the voltage of the power supply is divided to convert the pressure detected by the pressure sensor into a voltage and output it to the processing unit. When the pressure detected by the pressure sensor changes, the resistance of the pressure sensor changes, and the voltage output to the processing unit changes. The processing unit can determine whether the contact between the smart card and the electrical connection part is normal based on the voltage at the first end of the pressure sensor, thereby reducing the complexity of contact detection.

[0069] Exemplarily, the resistance value of the resistor R is R1, the resistance value of the resistor of the pressure sensor 20 is R2, the voltage of the power supply VCC is V1, and the voltage of the first end of the pressure sensor 20 is V2. The relationship between the resistance value of the resistor R, the resistance value of the resistor of the pressure sensor 20, the voltage of the power supply VCC, and the voltage of the first end of the pressure sensor 20 is as follows:

[0070]

[0071] When the pressure detected by the pressure sensor 20 changes, the resistance R2 of the resistor of the pressure sensor 20 changes, and the voltage V2 at the first end of the pressure sensor 20 changes. The processing unit 32 can determine whether the contact between the smart card and the electrical connection part 11 is normal according to the voltage V2 at the first end of the pressure sensor 20.

[0072] Exemplarily, in the processing unit 32, a voltage threshold may be set as a reference to determine whether the contact between the smart card and the electrical connection portion 11 is normal. When the voltage at the first end of the pressure sensor 20 detected by the processing unit 32 is greater than the voltage threshold, the contact between the smart card and the electrical connection portion 11 is normal. When the voltage at the first end of the pressure sensor 20 detected by the processing unit 32 is less than or equal to the voltage threshold, the contact between the smart card and the electrical connection portion 11 is abnormal.

[0073] Exemplarily, in addition to setting a voltage threshold as a reference, the processing unit 32 may also use the voltage at the first end of the pressure sensor 20 as a reference voltage before the smart card is inserted into the card holder. After the smart card is inserted into the card holder, the processing unit 32 determines whether the contact between the smart card and the electrical connection part 11 is normal based on the voltage at the first end of the pressure sensor 20 and the reference voltage. When the voltage at the first end of the pressure sensor 20 detected by the processing unit 32 is greater than the reference voltage, the contact between the smart card and the electrical connection part 11 is normal. When the voltage at the first end of the pressure sensor 20 detected by the processing unit 32 is less than or equal to the reference voltage, the contact between the smart card and the electrical connection part 11 is abnormal.

[0074] Exemplarily, the processing unit 32 may also send a prompt message through the screen of the electronic device to prompt the user when the smart card is in abnormal contact with the electrical connection portion 11 .

[0075] In one embodiment, if Figure 8 As shown, there are multiple pressure sensors 20 and resistors R, and the first end of each pressure sensor 20 is electrically connected to the second end of a different resistor R. The conversion circuit 31 also includes an analog-to-digital conversion circuit 311, which is electrically connected between each pressure sensor 20 and the processing unit 32. Multiple first ends of the analog-to-digital conversion circuit 311 are electrically connected to the first ends of different pressure sensors 20, and the second end of the analog-to-digital conversion circuit 311 is electrically connected to the processing unit 32.

[0076] In this embodiment, since the smart card includes multiple contacts, multiple pressure sensors are provided on the card holder, and the number of resistors of the corresponding conversion circuit is multiple. Since each resistor of the conversion circuit and the resistor of the corresponding pressure sensor constitute a voltage divider circuit, the processing unit can detect the voltage of the first end of the corresponding pressure sensor through each voltage divider circuit to determine whether the contact between the smart card and each electrical connection part is normal to improve the reliability of contact detection. At the same time, since the number of input ends of the processing unit is limited and the number of pressure sensors is large, if the first end of the pressure sensor is directly electrically connected to the input end of the processing unit, it will affect the function of the processing unit. By adding an analog-to-digital conversion circuit between the pressure sensor and the processing unit, the voltage of the first end of the pressure sensor is converted separately using multiple first ends of the analog-to-digital conversion circuit, thereby reducing the occupancy of the input end of the processing unit to improve the reliability of contact detection.

[0077] Exemplarily, when the number of pressure sensors 20 is small, such as 1, 2 or 3, the conversion circuit 31 may not include the analog-to-digital conversion circuit 311, and the multiple input ends of the processing unit 32 are respectively electrically connected to the first ends of different pressure sensors 20.

[0078] Exemplarily, when there are multiple electrical connection parts 11 and each electrical connection part 11 is provided with a pressure sensor 20, the voltage of the first end of each pressure sensor 20 can be detected respectively. The voltage of the first end of each pressure sensor 20 is averaged as the reference voltage. After the smart card is inserted into the card holder, the processing unit 32 determines whether the contact between the smart card and the electrical connection part 11 is normal according to the voltage of the first end of each pressure sensor 20 and the reference voltage. When the voltage of the first end of each pressure sensor 20 is greater than the reference voltage, the contact between the smart card and the electrical connection part 11 is normal. When the voltage of the first end of at least one pressure sensor 20 is less than or equal to the reference voltage, the contact between the smart card and the electrical connection part 11 is abnormal. Alternatively, the voltage of the first end of each pressure sensor 20 can be determined as the respective reference voltages. After the smart card is inserted into the card holder, the processing unit 32 determines whether the contact between the smart card and the electrical connection part 11 is normal according to the voltage of the first end of each pressure sensor 20 and the corresponding reference voltage. When the voltage at the first end of each pressure sensor 20 is greater than the corresponding reference voltage, the contact between the smart card and the electrical connection part 11 is normal. When the voltage at the first end of at least one pressure sensor 20 is less than or equal to the corresponding reference voltage, the contact between the smart card and the electrical connection part 11 is abnormal.

[0079] Exemplarily, the processing unit 32 includes a processor. The processor may be a processor of an electronic device or a separate processor, which is not limited here.

[0080] Exemplarily, the third terminal of the analog-to-digital conversion circuit 311 is used to be electrically connected to the power supply VCC, and the fourth terminal of the analog-to-digital conversion circuit 311 is used to be electrically connected to the ground terminal GND.

[0081] In one embodiment, the second end of the analog-to-digital conversion circuit 311 is electrically connected to the processing unit 32 via a communication bus.

[0082] In this embodiment, since the communication bus has a fast data transmission speed and occupies a small number of input terminals of the processing unit, the analog-to-digital conversion circuit is electrically connected to the processing unit through the communication bus, reducing the occupancy of the input terminals of the processing unit to improve the reliability of contact detection.

[0083] For example, the communication bus may be an Inter-Integrated Circuit (IIC) bus. The second end of the analog-to-digital conversion circuit 311 may be electrically connected to the processing unit 32 via a data input / output port (SWIO) and the IIC bus.

[0084] An exemplary embodiment of the present disclosure provides an electronic device, such as Fig. 9As shown, the electronic device includes a base 10, a pressure sensor 20, a processing unit 32, an analog-to-digital conversion circuit 311 and a resistor R. The number of bases 10 is 2. The number of pressure sensors 20 and resistors R is 12, and the number of first ends of the analog-to-digital conversion circuit 311 is 12.

The fixed end of each spring 111 is fixedly connected to the base 10 where it is located, and the free end of each spring 111 is provided with a pressure sensor 20. In one base 10, the 6 springs 111 are arranged in two rows and the free ends of the two rows of springs 111 are oriented in opposite directions. The first end of each resistor R is used to be electrically connected to the power supply VCC, and the second end of each resistor R is electrically connected to the first end of a pressure sensor 20 and a first end of the analog-to-digital conversion circuit 311, respectively. The second end of the analog-to-digital conversion circuit 311 is electrically connected to the processing unit 32 through the integrated circuit bus and the data input and output port, the third end of the analog-to-digital conversion circuit 311 is used to be electrically connected to the power supply VCC, and the fourth end of the analog-to-digital conversion circuit 311 is used to be electrically connected to the ground terminal GND. The processing unit 32 can determine whether the contact between the smart card and the spring 111 where it is located is normal according to the voltage of the first end of each pressure sensor 20, so as to perform contact detection.
