[0018] Figure 2 This is a schematic diagram of another function reset circuit provided in an embodiment of the present disclosure. DETAILED DESCRIPTION

[0019] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description in order to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples thereof.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The embodiments will now be described in detail with reference to the accompanying drawings.

[0021] Figure 1 This is a schematic diagram of the structure of a function reset circuit provided in an embodiment of the present disclosure, as shown below. Figure 1 As shown, the function reset circuit includes a power-off module 100 and a function execution module 200. The power-off module 100 is pluggable. The first terminal 201 of the function execution module 200 is connected to the negative power supply terminal 301 of the power supply module 300 through the power-off module 100, and the second terminal 202 of the function execution module 200 is connected to the positive power supply terminal 302 of the power supply module 300. The function execution module 200 has a power-off reset function. Specifically, the power-off module 100 is used to disconnect the power to the function execution module 200 when it is unplugged.

[0022] Specifically, the power-off module 100 can directly disconnect its internal connections by pulling out its internal conductive element, thereby disconnecting the connection between externally connected modules. Conversely, the power-off module 100 can also directly restore its internal connections by inserting the conductive element, thereby reconnecting the connection between externally connected modules. Since the first end 201 of the function execution module 200 is connected to the negative power supply end 301 of the power supply module 300 through the power-off module 100, when the conductive element of the power-off module 100 is pulled out, the connection between the first end 201 of the function execution module 200 and the negative power supply end 301 of the power supply module 300 can be directly severed, thus enabling the power-off module 100 to disconnect the function execution module 200 when it is pulled out. When the power-off module 100 removes the conducting element and then inserts the conducting element again, it can connect the first end 201 of the function execution module 200 with the negative power supply end 301 of the power supply module 300, thereby enabling the power-off module 100 to restore the power supply of the power module 300 to the function execution module 200 when it is inserted.

[0023] The function execution module 200 is located inside the electrical equipment 400, while the power-off module 100 is located outside the electrical equipment 400. When the electrical equipment 400 is operating normally, the power-off module 100 remains inserted, ensuring the power supply module 300 provides power to the function execution module 200, thus guaranteeing its normal operation. However, if the function execution module 200 malfunctions, it has a power-off reset function. Therefore, by removing the conductive element of the power-off module 100, the power supply from the power supply module 300 to the function execution module 200 is cut off, resetting the function execution module 200. Then, the conductive element of the power-off module 100 is reinserted, restoring the power supply from the power supply module 300 to the function execution module 200, thereby restarting the function execution module 200 and restoring it to normal operation. This disclosure eliminates the need to remove the function execution module 200 from the electrical equipment 400 and disconnect the power supply from the power module 300 after a malfunction occurs. Instead, the power supply from the power module 300 to the function execution module 200 can be directly disconnected by the power-off module 100 located outside the electrical equipment 400, thus resetting the function of the function execution module 200. Power can then be restored to the function execution module 200 to restore its normal operating state. This allows for a simple and convenient recovery of the function execution module 200 from an abnormal state to its normal operating state.

[0024] In some embodiments, the power-off module includes an electrical switch; a first end of the electrical switch is connected to the negative power supply terminal of the power supply module, and a second end of the electrical switch is connected to the first end of the function execution module; wherein the electrical switch is used to power off the function execution module in the unplugged state.

[0025] Specifically, the electrical switch can be a pluggable switch, which has a pluggable conducting element inside. When the conducting element is inserted into the electrical switch, the first end of the conducting element is connected to the first end of the electrical switch, and the second end of the conducting element is connected to the second end of the electrical switch, thereby making the first end of the electrical switch and the second end of the electrical switch conductive.

[0026] The function execution module is located inside the electrical equipment, while the electrical switch is located outside the equipment. Under normal operating conditions, the conducting element of the electrical switch remains inserted, ensuring continuity between the power module connected to the first end of the electrical switch and the function execution module connected to the second end. This maintains power supply to the function execution module, ensuring its normal operation. When the function execution module malfunctions, it has a power-off reset function. Therefore, by removing the conducting element of the electrical switch, the power supply to the function execution module is cut off, resetting the module. Then, the conducting element is reinserted to restore continuity between the power module and the function execution module, restarting the module and restoring it to normal operation. This disclosure eliminates the need to remove the function execution module from the electrical equipment and then cut off the power supply after a malfunction. Instead, the power supply to the function execution module can be directly cut off by an electrical switch located outside the electrical equipment, thereby resetting the function execution module. Then, the power supply to the function execution module can be restored to restore its normal working state. This makes it easy to restore the function execution module from an abnormal state to a normal working state.

[0027] In some embodiments, the electrical switch includes a first fuse in a fuse box; a first end of the first fuse is connected to the negative power supply terminal of the power module, and a second end of the first fuse is connected to the first end of the function execution module; wherein the first fuse is used to disconnect the power to the function execution module in the unplugged state.

[0028] Specifically, when the first fuse is inserted into the fuse box, its first end is connected to the negative power supply terminal of the power module, and its second end is connected to the first end of the function execution module, thus connecting the negative power supply terminal of the power module to the function execution module. When the first fuse is removed from the fuse box, the connection between the first end of the first fuse and the negative power supply terminal of the power module is broken, and the connection between the second end of the first fuse and the first end of the function execution module is also broken, thus disconnecting the negative power supply terminal of the power module from the function execution module.

[0029] The function execution module is located inside the electrical equipment, while the fuse box is located outside the equipment. Under normal operating conditions, the first fuse in the fuse box remains inserted, maintaining continuity between the power module and the function execution module, ensuring the power module supplies power to the function execution module and guarantees its normal operation. However, if the function execution module malfunctions, it has a power-off reset function. Therefore, by removing the first fuse from the fuse box, the power supply to the function execution module is cut off, resetting the module. Then, the first fuse is reinserted to restore continuity between the power module and the function execution module, restarting the module and restoring it to normal operation. This disclosure eliminates the need to remove the function execution module from the electrical equipment and then cut off the power supply after a malfunction. Instead, the power supply to the function execution module can be cut off directly through the fuse box located outside the electrical equipment by pulling out the first fuse, thereby resetting the function execution module. Then, the first fuse can be inserted back into the fuse box to restore the power supply to the function execution module and restore it to its normal working state. This makes it easy to restore the function execution module from an abnormal state to a normal working state.

[0030] In some embodiments, Figure 2 This is a schematic diagram of another function reset circuit provided in an embodiment of the present disclosure, as shown below. Figure 2 As shown, the function execution module includes: a power supply unit 210, an emergency call unit 220, a control unit 230, and a switch unit 240; the first terminal 241 of the switch unit 240 is connected to the negative power supply terminal 301 of the power supply module 300 through the power-off module 100, the second terminal 242 of the switch unit 240 is connected to the positive power supply terminal 302 of the power supply module 300, the third terminal 243 of the switch unit 240 is connected to the power supply unit 210, the fourth terminal 244 of the switch unit 240 is connected to the emergency call unit 220, and the control terminal 245 of the switch unit 240 is connected to the control unit 230; wherein, the control unit 230 is used to output a power supply switching signal; the switch unit 240 is used to switch the power supply unit 210 to supply power to the emergency call unit according to the power supply switching signal.

[0031] For example, taking a function execution module located inside the vehicle as an example, when the vehicle is in normal working condition, the switch unit 240 connects the power-off module 100 and the emergency call unit 220, and the power-off module 100 is also in the plugged-in state. At this time, the power supply module 300 supplies power to the emergency call unit 220 to maintain its normal operation. When the vehicle experiences an abnormal driving condition such as a collision or rollover, the control unit 230 outputs a power supply switching signal, causing the switch unit 240 to connect the power supply unit 210 and the emergency call unit 220. At this time, the power supply unit 210 supplies power to the emergency call unit 220 to avoid the problem that the power supply module 300 cannot supply power to the emergency call unit 220 when the vehicle is in an abnormal driving condition, thus preventing passengers from calling for help and ensuring the safety of passengers.

[0032] During normal vehicle use, if the emergency call unit 220 malfunctions, since the vehicle is not in an abnormal driving state, the switch unit 240 will not switch to the state where the power supply unit 210 supplies power to the emergency call unit 220. Therefore, the power supply from the power module 300 to the emergency call unit 220 can be cut off by directly removing the conductive element in the power-off module 100, thus de-energizing the emergency call unit 220 for function reset. Afterwards, the conductive element of the power-off module 100 is inserted to reconnect the power module 300 to the emergency call unit 220, restoring the power supply from the power module 300 to the emergency call unit 220, thereby restarting the emergency call unit 220 and restoring it to normal working condition. This disclosure eliminates the need to remove the function execution module from the vehicle and cut off the power supply from the power module 300 to the emergency call unit 220 when the emergency call unit 220 malfunctions and the vehicle is in normal working condition. Instead, the power supply to the emergency call unit 220 can be directly cut off by the power cut-off module 100 located outside the vehicle, thereby resetting the function of the emergency call unit 220. Then, the power supply to the emergency call unit 220 can be restored to restore its normal working state. This makes it easy to restore the emergency call unit 220 from an abnormal state to a normal working state.

[0033] In some embodiments, the control unit includes a controller and a CAN transceiver; the controller is connected to the CAN transceiver; the controller is used to output a power supply switching signal based on the hazardous scene signal received by the CAN transceiver.

[0034] For example, taking a function execution module located inside a vehicle as an example, the CAN transceiver connects to other sensors in the vehicle via the CAN bus. When the CAN transceiver receives signals indicating a driving hazard, such as an airbag deployment signal or a collision signal, it sends a hazard scene signal to the controller. Based on the received hazard scene signal, the controller outputs a power supply switching signal to the switching unit. The switching unit disconnects the emergency call unit from the power module while simultaneously connecting the emergency call unit to the power supply unit, allowing the power supply unit to power the emergency call unit, thus enabling the function execution module to operate independently. Therefore, this disclosure provides separate power to the emergency call unit via the power supply unit, avoiding the problem that the power module might fail to power the emergency call unit in the event of a vehicle malfunction, preventing passengers from calling for help through the emergency call unit, thereby ensuring the safety of the passengers.

[0035] It should be noted that the CAN transceiver receiving an airbag deployment signal or a vehicle collision signal is only an example. The CAN transceiver can also send a dangerous scenario signal to the controller based on other signals that indicate that the vehicle is encountering a driving hazard, but this is not specifically limited here.

[0036] In some embodiments, the control unit further includes an acceleration sensor; the acceleration sensor is connected to the controller; the controller is used to output a power supply switching signal based on a hazard occurrence signal sent by the acceleration sensor.

[0037] For example, taking a function execution module located inside a vehicle as an example, an acceleration sensor can detect the vehicle's speed. When a significant change in the vehicle's speed is detected within a short period, it can be considered that the vehicle is facing a driving hazard. At this time, the acceleration sensor sends a hazard occurrence signal to the controller. Based on the received hazard occurrence signal, the controller outputs a power supply switching signal to the switching unit. The switching unit disconnects the emergency call unit from the power module and simultaneously connects the emergency call unit to the power supply unit, allowing the power supply unit to supply power to the emergency call unit, thereby enabling the function execution module to operate independently. Therefore, this disclosure, by providing separate power to the emergency call unit through the power supply unit, avoids the problem that the power module cannot supply power to the emergency call unit in the event of a vehicle driving malfunction, thus preventing passengers from calling for help through the emergency call unit and ensuring the safety of passengers.

[0038] In some embodiments, the control unit further includes a collision sensor; the collision sensor is connected to the controller; the controller is used to output a power supply switching signal based on the impact signal sent by the collision sensor.

[0039] For example, taking a function execution module located inside a vehicle as an example, a collision sensor can detect vehicle collisions. When a significant impact is detected, it can be considered that the vehicle is in a driving hazard. At this time, the collision sensor sends a collision signal to the controller. Based on the received collision signal, the controller outputs a power supply switching signal to the switching unit. The switching unit disconnects the emergency call unit from the power module and simultaneously connects the emergency call unit to the power supply unit, allowing the power supply unit to supply power to the emergency call unit, thereby enabling the function execution module to operate independently. Therefore, this disclosure provides a separate power supply to the emergency call unit through the power supply unit, avoiding the problem that the power module cannot supply power to the emergency call unit in the event of a vehicle malfunction, thus preventing passengers from calling for help through the emergency call unit and ensuring the safety of passengers.
