Detailed Implementation

[0031] The embodiments of this application are described in detail below. These embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0032] In related technologies, portable electronic devices are designed to be as compact as possible to minimize their size and facilitate portability. However, when an electronic device's chip needs upgrading, the casing must be disassembled to remove it. Yet, the compact internal structure of these devices makes disassembling and removing the chip difficult, inefficient, and prone to damaging the components.

[0033] To address the aforementioned technical problems, this application provides an electronic device (as shown in Figures 1 to 9).

[0034] Referring to FIG1, the electronic device 100 provided in this embodiment may include a housing 10, a first connector 20, a second connector 30, a chip 40, and a switch module 50. The first connector 20 and the second connector 30 are disposed on the housing 10. The chip 40 is disposed within the housing 10. The switch module 50 connects the first connector 20 and the second connector 30 to the chip 40. The switch module 50 is configured to connect the second connector 30 and the chip 40 based on a signal received through the first connector 20, allowing an external programmer 200 to program the chip 40 via the second connector 30.

[0035] In the electronic device 100 provided in this application embodiment, the unused pins on the first connector 20 and the second connector 30 can be used to connect to an external programmer 200. When the chip 40 of the portable electronic device 100 needs to be upgraded, the external programmer 200 can be connected to the first connector 20 and the second connector 30 to realize the programming of the chip 40. It is not necessary to disassemble the casing 10 of the electronic device 100, making the operation simpler, the electronic device 100 less prone to damage, and no additional connectors are needed. This can save the components of the electronic device 100, control the size of the electronic device 100, and further improve the portability of the electronic device 100.

[0036] Specifically, the chip 40 can be a chip 40 inside the electronic device 100, the chip 40 is disposed inside the housing 10 of the electronic device 100, the connector is disposed on the housing 10 of the electronic device 100, and the first connector 20 and the second connector 30 disposed on the housing 10 can be connected to an external programmer 200.

[0037] The switch module 50 is disposed within the housing 10 of the electronic device 100, and is connected between the second connector 30 and the chip 40. When the switch module 50 is off, the connection between the chip 40 and the second connector 30 is broken. When the switch module 50 is on, the chip 40 and the second connector 30 are connected.

[0038] When the external programmer 200 is connected to the first connector 20 and the second connector 30, the unused pins on the first connector 20 and the second connector 30 can be used to connect to the external programmer 200. If the external programmer 200 needs to program the chip 40, the external programmer 200 can provide the corresponding control signal to the switch module 50 through the first connector 20, so that the switch module 50 is turned on, and the chip 40 is connected to the second connector 30. In this way, the external programmer 200 can program the chip 40 through the second connector 30.

[0039] Thus, when the chip 40 of the portable electronic device 100 needs to be upgraded, the external programmer 200 can be connected to the first connector 20 and the second connector 30 to program the chip 40 without disassembling the casing 10 of the electronic device 100. This makes the operation simpler, the electronic device 100 less prone to damage, and eliminates the need for additional connectors. It saves on the components of the electronic device 100, controls its size, and further enhances its portability.

[0040] Referring to FIG2, in some embodiments, the first connector 20 includes a programming enable terminal 21, and the switch module 50 is configured to connect the second connector 30 and the chip 40 or disconnect the second connector 30 and the chip 40 based on an enable signal received from the programming enable terminal 21.

[0041] Specifically, when the first connector 20 is not connected to the external programmer 200, or when the external programmer 200 is not programming the chip 40, the enable signal connected to the programming enable terminal 21 can control the switch module 50 to disconnect, and the second connector 30 will be disconnected from the chip 40. At this time, the programming pins on the second connector 30 can be used as pins for other functions.

[0042] When the first connector 20 is connected to the external programmer 200 and the external programmer 200 needs to program the chip 40, the enable signal connected to the programming enable terminal 21 can control the switch module 50 to be turned on, and the second connector 30 is connected to the chip 40.

[0043] Referring to Figure 3, in some embodiments, the second connector 30 includes a programming data terminal 31. The programming data terminal 31 is connected to the chip 40 via a switch module 50, which is configured to connect the programming data terminal 31 and the chip 40 based on the signal input to the first connector 20, so as to allow an external programmer 200 to program the chip 40 through the programming data terminal 31.

[0044] Specifically, when the second connector 30 is not connected to the external programmer 200, or when the switch module 50 is disconnected, the external programmer 200 does not program the chip 40 through the programming data terminal 31. At this time, the programming data terminal 31 can be used as a pin for other functions.

[0045] When the second connector 30 is connected to the external programmer 200 and the switch module 50 is turned on, the programming data terminal 31 of the second connector 30 can be connected to the chip 40, thereby enabling the external programmer 200 to program the program to be programmed to the chip 40 through the programming data terminal 31.

[0046] In some implementations, the first connector 20 and / or the second connector 30 include a Type-C connector.

[0047] Specifically, the first connector 20 may include a Type-C connector, and the programming data terminal 31 may be an unused pin on the Type-C connector. The second connector 30 may also be a Type-C connector, and the programming enable terminal 21 may be an unused pin on the Type-C connector.

[0048] The Type-C connector is a common connector in electronic devices 100. Most Type-C connectors in electronic devices 100 do not have all their pins functional, resulting in a high rate of idle pins. Programming the remaining unused pins of the Type-C interface can increase pin utilization.

[0049] Taking Figures 2 and 3 as examples, the first connector 20 may include connector TYPE-C1, and the second connector 30 may include TYPE-C2. The programming enable terminal 21 may be the V+5 pin of connector TYPE-C1, and the programming data terminal 31 may be the C_ICPDA pin and C_ICPCK pin of connector TYPE-C2. The C_ICPDA pin and C_ICPCK pin of connector TYPE-C2 can be connected through the switch module 50 chip 40.

[0050] When the first connector 20 and the second connector 30 are connected to the external programmer 200, the external programmer 200 can provide a programming enable signal through the V+5 pin of connector TYPE-C1, and the C_ICPDA pin and C_ICPCK pin of connector TYPE-C2 can start receiving the program from the external programmer 200 and programming the program to chip 40.

[0051] The programming enable signal can be a voltage signal or a current signal provided by the external programmer 200. For example, during the programming process of the external programmer 200, the external programmer 200 first provides a 5V voltage signal to the V+5 pin of connector TYPE-C1. After the V+5 pin of connector TYPE-C1 receives the 5V voltage signal, the C_ICPDA pin and C_ICPCK pin of connector TYPE-C2 begin to receive the program from the external programmer 200.

[0052] After the V+5 pin of connector TYPE-C1 receives a 5V voltage signal, the first connector 20 and the second connector 30 will not be used as connectors for other functional pins, which can prevent the external programmer 200 from being interfered with during the programming process.

[0053] If the programming enable pin 21 is not connected to the programming enable signal, the programming data pin 31 can be used as a pin for other functions. If the V+5 pin of connector TYPE-C1 does not receive a 5V voltage signal, the C_ICPDA pin and C_ICPCK pin of connector TYPE-C2 can be used as pins for other functions.

[0054] Referring to FIG2, in some embodiments, the electronic device 100 includes at least two chips 40, the first connector 20 includes a gating terminal 22, and the switch module 50 is configured to select to connect the second connector 30 to either chip 40 based on a gating signal accessed by the gating terminal 22.

[0055] Referring to Figure 5, the switch module 50 can selectively connect the external programmer 200 to any one of the chips 40 of the electronic device 100, allowing the external programmer 200 to sequentially program multiple chips 40. Thus, when a chip 40 of the portable electronic device 100 needs upgrading, the switch module 50 can enable the external programmer 200 to program each chip 40 without disassembling the casing 10 of the electronic device 100. This simplifies operation, reduces the risk of damage to the electronic device 100, further saves on the components of the electronic device 100, controls its size, and improves its portability.

[0056] Specifically, the electronic device 100 may include multiple chips 40. The switch module 50 may be a single-pole multi-throw switch. When the external programmer 200 is connected to the connector, the external programmer 200 can provide a gating signal through the gating terminal 22 to control the single-pole multi-throw switch to enable any one of the chips 40 to be connected to the programming data terminal 31, so that the external programmer 200 can program any one of the chips 40 through the programming data terminal 31.

[0057] Referring to FIG6, in some embodiments of this application, the chip 40 of the electronic device 100 may include a first chip 41 and a second chip 42. The first chip 41 may be the main control chip of the microprocessor (CPU) controlling the electronic device 100. The first chip 41 integrates various control current and functional circuits of the electronic device 100, and can uniformly coordinate and manage the hardware of the electronic device 100 and control the various functions of the electronic device 100.

[0058] The second chip 42 can be a battery management system (BMS) chip, which includes functions such as battery monitoring, battery protection, and charge / discharge control. The second chip 42 can monitor parameters such as battery voltage, current, temperature, and state of charge in real time. This monitoring data provides a detailed understanding of the battery, helps determine its operating status and health condition, and ensures safe battery operation by implementing various protection mechanisms, such as disconnecting the battery's charge / discharge circuit, adjusting current limits, or triggering alarms.

[0059] The strobe terminal 22 can be the IN pin of the connector TYPE-C1. The external programmer 200 can control the switch module 50 to select between connecting the first chip 41 and the programming data terminal 31 or connecting the second chip 42 and the programming connection terminal by providing a strobe signal to the IN pin.

[0060] For example, when the external programmer 200 provides a high-level strobe signal, the switch module 50 connects the first chip 41 and the programming data terminal 31, allowing the external programmer 200 to program the first chip 41. When the external programmer 200 provides a low-level strobe signal, the switch module 50 connects the second chip 42 and the programming data terminal 31, allowing the external programmer 200 to program the second chip 42.

[0061] In some embodiments of this application, connector TYPE-C1 and connector TYPE-C2 can be connectors whose signals do not interfere with each other. When the external programmer 200 is programming, the signals connected to the V+5 pin and the IN pin will not affect the signals connected to the C_ICPDA pin and the C_ICPCK pin, which can improve the anti-interference capability of the external programmer 200 during programming.

[0062] Referring to Figures 4 and 5, in some embodiments, the second connector 30 includes a programming data terminal 31, and the switch module 50 includes a first connection terminal 51, a second connection terminal 52, and a third connection terminal 53. The first connection terminal 51 is connected to the programming data terminal 31, the second connection terminal 52 is connected to the first chip 41, and the third connection terminal 53 is connected to the second chip 42. The switch module 50 is configured to connect the first connection terminal 51 and the second connection terminal 52, or connect the first connection terminal 51 and the third connection terminal 53, based on a gating signal received at the gating terminal 22, so as to allow an external programmer 200 to program the first chip 41 or the second chip 42 through the programming data terminal 31.

[0063] Taking Figure 4 as an example, the switch module 50 may include a COM pin, an IN pin, a NO pin, and an NC pin. The first connection terminal 51 may be the COM pin, the second connection terminal 52 may be the NO pin, and the third connection terminal 53 may be the NC pin. The V+ pin of the switch module 50 can connect to the strobe signal provided by connector TYPE-C1, the COM pin can connect to the programming data terminal 31 of connector TYPE-C2, the NO pin can connect to the first chip 41, and the NC pin can connect to the second chip 42. The switch module 50 can connect the COM pin and the NO pin, or connect the COM pin and the NC pin, according to the received strobe signal, so that the programming data terminal 31 is connected to the first chip 41, or the programming data terminal 31 is connected to the second chip 42, allowing the external programmer 200 to program the first chip 41 or the second chip 42 through the programming data terminal 31.

[0064] Referring to Figure 2, in some embodiments, the first connector 20 includes a programming enable terminal 21, and the switch module 50 includes a power supply terminal 54. The programming enable terminal 21 is configured to supply power to the power supply terminal 54 based on an access enable signal. When the programming enable terminal 21 supplies power to the power supply terminal 54, the switch module 50 is configured to connect the first connection terminal 51 to the second connection terminal 52, or connect the first connection terminal 51 to the third connection terminal 53.

[0065] Specifically, the power supply side may also include the V+ pins of chip U4 and chip U5, and the V+ pin of switch module 50 can be connected to the V+5 pin of connector TYPE-C1.

[0066] When the first connector 20 is not connected to the external programmer 200, or when the external programmer 200 is not programming the chip, the V+5 pin of the connector TYPE-C1 does not provide the corresponding power supply voltage to the V+ pins of the chips U4 and U5. The chips U4 and U5 can disconnect the connection between the COM pin and the NO pin, and disconnect the connection between the COM pin and the NC pin.

[0067] The switch module also includes a controlled terminal 55, which may include the IN pins of chips U4 and U5. When the first connector 20 is connected to an external programmer 200, and the external programmer 200 needs to program the chips, the V+5 pin of connector TYPE-C1 can provide the corresponding power supply voltage to the V+ pins of chips U4 and U5. At this time, chips U4 and U5 can connect the COM pin and the NO pin, or connect the COM pin and the NC pin, according to the strobe signal connected to the controlled terminal 55.

[0068] Referring to FIG5, in some embodiments, the switch module 50 includes a first diode 61, which is reverse-connected between the power supply terminal 54 and the power supply of the electronic device 100, or the switch module 50 includes a second diode 62, which is reverse-connected between the first connection terminal 51 and the ground electrode.

[0069] Specifically, the first diode 61 can be diode D1, and the voltage source of electronic device 100 can provide a +5V voltage. Diode D1 can be connected in reverse between power supply terminal 54 and the voltage source of electronic device 100. Since diode D1 is reverse-biased and cut off, electronic device 100 is prevented from supplying power to the V+ pins of chip U4 and chip U5.

[0070] The second diode 62 can act as a Zener diode, stabilizing the voltage at the COM pins of chips U4 and U5 against the reverse voltage of the second diode 62. The COM pins of chips U4 and U5 are used to connect the program to be programmed into the chips; stabilizing the voltage at the COM pins of chips U4 and U5 improves program stability.

[0071] The second diode 62 can be either diode ESD1 or diode ESD2. Diode ESD1 is connected in reverse between the COM pin of chip U4 and ground, and diode ESD2 is connected in reverse between the COM pin of chip U5 and ground. Because diodes ESD1 and ESD2 are reverse-biased and cut off, the COM pins of chip U4 and U5 cannot be grounded to form a circuit.

[0072] After diodes ESD1 and ESD2 are broken down, they can act as Zener diodes, stabilizing the voltage at the COM pin of chip U4 and the COM pin of chip U5 against the reverse voltage of the second diode 62.

[0073] In some embodiments of this application, the second diode 62 may be an electrostatic discharge diode, which can release static electricity and provide electrostatic protection for electronic devices within the electronic device 100.

[0074] In some embodiments, the switch module 50 includes at least two first connection terminals 51, and the second connector 30 includes at least two programming data terminals 31, each first connection terminal 51 being connected to a corresponding programming data terminal 31. When the switch module 50 is configured to connect the first connection terminal 51 and the second connection terminal 52, the second connection terminal 52 is connected to the corresponding programming data terminal 31 through at least two first connection terminals 51, allowing an external programmer 200 to program the first chip 41 through the corresponding programming data terminal 31. When the switch module 50 is configured to connect the first connection terminal 51 and the third connection terminal 53, the third connection terminal 53 is connected to the corresponding programming data terminal 31 through at least two first connection terminals 51, allowing an external programmer 200 to program the second chip 42 through the corresponding programming data terminal 31.

[0075] Specifically, taking Figure 3 as an example, the C_ICPDA pin and the C_ICPCK pin can be two programming data terminals 31 of the second connector 30.

[0076] Taking Figure 4 as an example, the switch module 50 may include two COM pins, a NO pin, and an NC pin. One COM pin can be connected to the C_ICPDA pin, and the other COM pin can be connected to the C_ICPCK pin.

[0077] Taking Figure 6 as an example, the MAIN_ICPDA and MAIN_ICPCK pins can be signal terminals of the first chip 41, and the BMS_ICPDA and BMS_ICPCK pins can be signal terminals of the second chip 42. One NO pin can be connected to the MAIN_ICPDA pin, and the other NO pin can be connected to the MAIN_ICPCK pin. One NC pin can be connected to the BMS_ICPDA pin, and the other NC pin can be connected to the BMS_ICPCK pin.

[0078] With the COM pin and NO pin connected, the external programmer 200 can program the MAIN_ICPDA pin through the C_ICPDA pin and program the MAIN_ICPCK pin through the C_ICPCK pin, thus enabling the external programmer 200 to program the first chip 41.

[0079] With the COM pin and NC pin connected, the external programmer 200 can program the program to the BMS_ICPDA pin via the C_ICPDA pin and program the program to the BMS_ICPCK pin via the C_ICPCK pin, thus enabling the external programmer 200 to program the program to the second chip 42.

[0080] Referring to Figures 5 and 6, in some embodiments, the switch module 50 includes a first switch unit 56 and a second switch unit 57. The first switch unit 56 is connected to a corresponding programming data terminal 31 via a first connection terminal 51, and the second switch unit 57 is also connected to the corresponding programming data terminal 31 via a first connection terminal 51. Under the control of a selection signal, the first switch unit 56 selects to connect a first connection terminal 51 to a corresponding second connection terminal 52, and the second switch unit 57 connects a first connection terminal 51 to a corresponding second connection terminal 52; or the first switch unit 56 selects to connect a first connection terminal 51 to a corresponding third connection terminal 53, and the second switch unit 57 connects a first connection terminal 51 to a corresponding third connection terminal 53.

[0081] Specifically, the first switching unit 56 can be chip U4, and the second switching unit 57 can be chip U5. Chip U4 can be connected to the C_ICPDA pin via the COM pin, the MAIN_ICPDA pin via the NO pin, and the BMS_ICPDA pin via the NC pin. Chip U5 can be connected to the C_ICPCK pin via the COM pin, the MAIN_ICPCK pin via the NO pin, and the BMS_ICPCK pin via the NC pin.

[0082] When the IN pin is connected to the first voltage level, chip U4 can connect to the C_ICPDA pin and the MAIN_ICPDA pin, and chip U5 can connect to the C_ICPCK pin and the MAIN_ICPCK pin. When the IN pin is connected to the second voltage level, chip U4 can connect to the C_ICPDA pin and the BMS_ICPDA pin, and chip U5 can connect to the C_ICPCK pin and the BMS_ICPCK pin.

[0083] The first voltage level can be high and the second voltage level can be low, or the first voltage level can be low and the second voltage level can be high.

[0084] Referring to FIG7, the electronic device 100 includes a battery 70 disposed within a housing 10. A first connector 20 is connected to the battery 70 to allow the battery 70 to be charged and discharged through the first connector 20, or a second connector 30 is connected to the battery 70 to allow the battery 70 to be charged and discharged through the second connector 30, or both the first connector 20 and the second connector 30 are connected to the battery 70 to allow the battery 70 to be charged and discharged through the first connector 20 and / or the second connector 30.

[0085] Specifically, the battery 70 can be an internal power source for the electronic device 100. The battery 70 can be a lithium battery or other rechargeable batteries. Both the battery 70 and the chip are housed within the casing 10 of the electronic device 100. The first connector 20 and the second connector 30 are disposed on the casing 10 of the electronic device 100. The first connector 20 and the second connector 30 disposed on the casing 10 can be connected to other devices. The other devices connected to the first connector 20 and the second connector 30 can be electrical appliances, chargers, or external programmers 200.

[0086] The first connector 20 and the second connector 30 can serve as connectors for charging and discharging the battery 70. That is, the battery 70 can be charged and discharged externally through the first connector 20, and the battery 70 can be charged and discharged externally through the second connector 30. When the connector is connected to a power device, the battery 70, located inside the housing 10, can communicate with the power device located outside the housing 10 through the connector, and the battery 70 discharges to the power device. When the connector is connected to a charger, the charger located outside the housing 10 can communicate with the battery 70 located inside the housing 10 through the connector, and the charger charges the battery 70.

[0087] Both the first connector 20 and the second connector 30 can serve as bidirectional charging and discharging interfaces for the battery 70. The first protocol chip 71 can control the charging and discharging power of the battery 70 to the first connector 20, and the second protocol chip 72 can control the charging and discharging power of the battery 70 to the second connector 30, thereby enabling fast charging of the battery 70.

[0088] Specifically, taking Figure 8 as an example, the first protocol chip 71 can be chip U7, and the second protocol chip 72 can be chip U8. The first protocol chip 71 and the second protocol chip 72 can support multiple charging and discharging protocols, such as PD (Power Delivery) protocol, QC (Quick Charge) protocol, Huawei fast charging protocol, and Samsung fast charging protocol. The first protocol chip 71 and the second chip 72 can control the charging and discharging power of the battery 70 to achieve fast charging of the battery 70.

[0089] For example, the first protocol chip 71 and the second protocol chip 72 can be chips that support the PD protocol. The PD protocol enables standardized communication between USB interface devices and supports DC power communication for fast charging. When the battery 70 charges and discharges through the first connector 20, the first protocol chip 71 obtains the charging and discharging request and determines the charging and discharging current and voltage of the battery 70 based on the charging and discharging request and the charging and discharging algorithm built into the first protocol chip 71, thereby realizing fast charging of the battery 70.

[0090] Referring to FIG9, in some embodiments, the electronic device 100 further includes a third connector 80 configured to connect to an external load, including at least one of a starter motor and a vehicle battery. The battery 70 is connected to the third connector 80 to allow the battery 70 to charge the external load through the third connector 80.

[0091] The electrical energy of electronic device 100 can be used to start the car. When the starting device and the car battery lack sufficient power, the car cannot start normally. The connector can be connected to the car battery or the starting device. The battery 70 of electronic device 100 can output electrical energy to the car battery or the starting device through the connector, enabling the car to start normally. In this way, electronic device 100 can serve as a starting power source for the car, reducing the footprint of in-vehicle equipment and making it more convenient to use and carry.
