Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, article or device including the element. "Plurality" means greater than or equal to two.

[0030] The embodiments of the present application first provide an emergency unlocking device. Refer to Figure 1 , the emergency unlocking device includes an emergency controller 11, a first power supply circuit 12 and a second power supply circuit 13.

[0031] The emergency controller 11 is used to send an emergency unlocking signal, and the emergency unlocking signal is used to control the unlocking of the vehicle door. Here, the vehicle door includes any door body structure with locking and unlocking functions, such as the driver's door, the front passenger door, the rear doors, and the tailgate of the vehicle.

[0032] The specific structure of the emergency controller 11 is not limited. As an example, refer to Figure 2 , the emergency controller 11 may include a power supply chip 111, a control chip 112 and a driver chip 113. The power supply chip 111 is used to connect with the first power supply circuit 12 and the second power supply circuit 13 to supply power to the control chip 112 and the driver chip 113. The control chip 112 is used to receive a control signal and control the driver chip 113 to generate and send an emergency unlocking signal. The specific implementation manners of the functions of the above-mentioned chips can refer to the relevant technologies in the art and will not be elaborated here.

[0033] The first power supply circuit 12 is connected to the emergency controller 11 and the main power supply X of the vehicle. In this way, the first power supply circuit 12 can supply power to the emergency controller 11 by means of the main power supply X of the vehicle. The main power supply X of the vehicle here specifically refers to the power supply used to supply power to each functional component of the vehicle in the normal driving state of the vehicle.

[0034] The second power supply circuit 13 is connected to the emergency controller 11 and is connected in parallel with the first power supply circuit 12. The second power supply circuit 13 includes a backup power supply 131. When the power supply of the main power supply X is abnormal, the backup power supply 131 supplies power to the emergency controller 11.

[0035] The backup power supply 131 here specifically refers to a power supply independent of the main power supply X. As an example, the backup power supply 131 can be only used to supply power to the emergency controller 11 and is not used to supply power to other functional components of the vehicle.

[0036] In this embodiment, the emergency unlocking device is configured with a first power supply circuit 12 and a second power supply circuit 13 connected in parallel, and the second power supply circuit 13 is equipped with a backup power supply 131. In this way, in an emergency state where the power supply of the main power supply X is abnormal due to reasons such as traffic accidents and battery thermal runaway, the backup power supply 131 can be used to supply power to the emergency controller 11, enabling the driver and passengers to unlock the door Y in the above situations and reducing the possibility of the driver and passengers being trapped in the vehicle.

[0037] It should be noted that the emergency unlocking device of this embodiment is used in parallel with the main unlocking device of the vehicle (the device for unlocking the door Y in the normal state of the vehicle). That is, the emergency unlocking device can be installed on the vehicle when the vehicle is already equipped with the main unlocking device, and either the emergency unlocking device or the main unlocking device can independently unlock the door Y.

[0038] In some embodiments, referring to Figure 3 , the emergency unlocking device further includes a charging circuit 14. The charging circuit 14 is connected to the main power supply X and the backup power supply 131 to charge the backup power supply 131 when the power supply of the main power supply X is normal.

[0039] In this embodiment, the emergency unlocking device is provided with a charging circuit 14. In this way, when the power supply of the main power supply X is normal, the backup power supply 131 can be charged to ensure that the backup power supply 131 has relatively sufficient power to supply power to the emergency controller 11 in an emergency state as much as possible, further reducing the possibility of the driver and passengers being trapped in the vehicle.

[0040] In some embodiments, referring to Figure 3, the charging circuit 14 specifically includes a charging chip 141 and a first diode 142. The charging chip 141 is connected to the backup power supply 131 and is mainly used to control the charging function. The anode of the first diode 142 is connected to the main power supply X, and the cathode is connected to the charging chip 141. In this way, the current can only flow from the main power supply X to the backup power supply 131, avoiding reverse charging of the backup power supply 131 to the main power supply X when the main power supply X has abnormal power supply, so as to ensure that the backup power supply 131 has relatively sufficient power to supply power to the emergency controller 11 in the emergency state as much as possible.

[0041] In some other embodiments, as a supplement or alternative, other methods can also be used to charge the backup power supply 131. For example, in a range-extended vehicle, the backup power supply 131 can be connected to a range extender for charging. Another example is that in a fuel vehicle, the backup power supply 131 can be connected to the vehicle's engine for charging. Another example is that a charging socket can be set to allow charging of the backup power supply 131 through a mobile power source or the like.

[0042] In some other embodiments, the backup power supply 131 can also be a non-rechargeable primary battery.

[0043] In some embodiments, referring to Figure 1 and Figure 3 , the voltage of the backup power supply 131 is less than the voltage of the main power supply X. The first power supply circuit 12 includes a second diode 121. The anode of the second diode 121 is connected to the main power supply X, and the cathode is connected to the emergency controller 11. The second power supply circuit 13 includes a third diode 132. The anode of the third diode 132 is connected to the backup power supply 131, and the cathode is connected to the emergency controller 11.

[0044] In this embodiment, since the voltage of the backup power supply 131 is less than the voltage of the main power supply X, therefore, in the state where the main power supply X supplies power normally, the voltage on the side of the emergency controller 11 will be higher than the voltage of the backup power supply 131. In this way, the second diode 121 will be turned on, while the third diode 132 cannot be turned on, enabling the main power supply X to supply power to the emergency controller 11. In the state where the main power supply X has abnormal power supply, the voltage of the first power supply circuit 12 drops to 0. Therefore, the second diode 121 automatically closes, and the third diode 132 will be automatically turned on. In this way, automatic switching between the main power supply X power supply and the backup power supply 131 power supply is achieved. This switching method is realized by a mechanical structure and has high reliability.

[0045] In some other embodiments, referring to Figure 4, the emergency unlocking device may include a changeover switch 15. The first power supply circuit 12 and the second power supply circuit 13 may be connected to the emergency controller 11 through the changeover switch 15. In this way, the switching between the main power supply X and the backup power supply 131 is realized. The specific structure of the changeover switch 15 may refer to the related technologies in the art and will not be elaborated here.

[0046] In some embodiments, referring to Figure 5 , the emergency controller 11 includes a control switch 114. The emergency unlocking device further includes an emergency operating member 16. The emergency operating member 16 is mechanically connected to the control switch 114. When the emergency operating member 16 is operated, it drives the control switch 114 to act so that the emergency controller 11 issues an emergency unlocking signal.

[0047] It can be understood that in the related technologies, the main unlocking device is usually connected to the vehicle's central control system and / or other hardware control circuits and issues an unlocking signal under the control of the above control components. The function realization of the above components usually depends on the power supply of the main power supply X. Therefore, in an emergency, the above control components may also fail to work properly. In addition, even when the main power supply X is normally powered, the above control components may also fail to work properly due to circuit failures.

[0048] For this reason, in this embodiment, the emergency unlocking device is configured with an emergency operating member 16 independent of the above control components. In this way, the decoupling of the main unlocking device and the emergency unlocking device in the control link is realized, and the emergency controller 11 can be controlled to issue an emergency unlocking signal when the above control components cannot work properly, reducing the possibility that the vehicle occupants are trapped in the vehicle.

[0049] Furthermore, in this embodiment, the emergency operating member 16 is used to control the emergency controller 11 to issue an emergency unlocking signal by mechanically driving the control switch 114 to act. The circuit structure of this mechanical drive structure is relatively simple, the failure rate is relatively low, and the reliability is relatively high.

[0050] In some embodiments, the emergency controller 11 is only connected to the emergency operating member 16, and the emergency operating member 16 is also only connected to the emergency controller 11. In this way, the independence of the control link of the emergency operating member 16 is further improved, and the probability that the connection circuit between the emergency operating member 16 and the emergency controller 11 fails due to circuit failures of other related components is reduced.

[0051] In some other embodiments, the emergency controller 11 may also be connected to the emergency operating member 16 and the above control components at the same time.

[0052] The specific structure of the emergency operating member 16 and the specific implementation manner of its mechanical connection with the control switch 114 are not limited.

[0053] In some embodiments, the emergency operating member 16 includes a button structure or a handle structure, thereby facilitating operation by the driver and passengers.

[0054] In some embodiments, the emergency operating member 16 includes a damping structure. In this way, the driver and passengers need to apply a force greater than the threshold value to operate the emergency operating member 16, thereby reducing the probability of accidental unlocking of the door Y caused by misoperation of the emergency operating member 16, especially reducing the probability of misoperation of the emergency operating member 16 by children.

[0055] In some embodiments, the emergency operating member 16 is disposed on one side of the driver's seat, one side of the driver's door Y, or one side of the center console, such as on the bottom side of the driver's seat, the bottom side of the driver's door Y, the bottom side of the center console, and so on. In some embodiments, the position where the emergency operating member 16 is disposed can be relatively far from other operation buttons of the vehicle to reduce the probability of misoperation.

[0056] In some embodiments, the number of the emergency operating members 16 is multiple, and they are respectively disposed at different positions of the vehicle. When any one of the emergency operating members 16 is operated, the emergency controller 11 issues an emergency unlocking signal.

[0057] As an example, multiple emergency operating members 16 can be disposed on different sides of the driver's seat, thereby reducing the possibility that the driver cannot operate the emergency operating member 16 due to limited movement. A part of the multiple emergency operating members 16 can also be disposed on the side of the passenger seat or the side of the rear seat. In this way, in the case where the driver loses the ability to operate, the passengers can operate the emergency operating member 16.

[0058] Multiple emergency operating members 16 can be all connected to the control switch 114, or multiple control switches 114 can also be provided and respectively connected to the multiple emergency operating members 16, so as to realize that when any one of the emergency operating members 16 is operated, the emergency controller 11 issues an emergency unlocking signal.

[0059] In some embodiments, referring to Figure 5 , the emergency operating device further includes a plurality of emergency unlocking switches 17 provided in one-to-one correspondence with each door Y. The emergency controller 11 is connected to each emergency unlocking switch 17 to send an emergency unlocking signal to each emergency unlocking switch 17. The emergency unlocking switch 17 acts in response to the camera unlocking signal to unlock the corresponding door Y.

[0060] It can be understood that the main unlocking device of the vehicle is usually configured with unlocking switches corresponding to each door Y one by one, but there is also a possibility of failure in the connection link between the main controller and the unlocking switches. Therefore, in this embodiment, the emergency unlocking device is additionally provided with independent emergency unlocking switches 17, so as to further improve the independence of the emergency unlocking device and reduce the possibility that the driver and passengers are trapped in the vehicle.

[0061] In some embodiments, the emergency operation device further includes a power component. The power component is connected to the first power supply circuit 12 and the second power supply circuit 13, enabling the main power supply X or the backup power supply 131 to supply electrical energy to the power component. The power component is also connected to the emergency controller 11. After the emergency unlocking switch 17 unlocks the vehicle door Y, the emergency controller 11 can further send an emergency door opening signal to the power component, causing the power component to actuate and drive the vehicle door Y to open. In this way, one-key unlocking and door opening in an emergency state can be achieved. Of course, the power component may not be provided. After the emergency unlocking switch 17 unlocks the vehicle door Y, the vehicle door Y can be manually opened by the driver or passenger.

[0062] An embodiment of the present application further provides an unlocking system. Referring to Figure 6 , the operating system includes a main unlocking device and an emergency unlocking device.

[0063] The main unlocking device includes a main controller 21. The main controller 21 is connected to the main power supply X of the vehicle and is used to send an unlocking signal.

[0064] The main unlocking device can be any one of the vehicle door Y unlocking devices provided in the related art, and no limitation is imposed thereon.

[0065] The emergency unlocking device is the emergency unlocking device described in any of the above embodiments.

[0066] The unlocking system of the embodiment of the present application has all the advantages of the emergency unlocking device described in any of the above embodiments, and will not be elaborated herein.

[0067] In some embodiments, the main controller 21 is connected to the vehicle's central control system Z to send an unlocking signal under the control of the central control system Z. The emergency unlocking device includes an emergency operation member 16. The emergency operation member 16 is connected to the emergency controller 11 to control the emergency controller 11 to send an emergency unlocking signal.

[0068] As mentioned above, this realizes the decoupling of the main unlocking device and the emergency unlocking device in the control link, and can further control the emergency controller 11 to send an emergency unlocking signal when the central control system Z fails to work properly, reducing the possibility of the driver or passenger being trapped in the vehicle.

[0069] The specific technical details of the emergency operation member 16 can be referred to the relevant part of the above description, and will not be elaborated herein.

[0070] In some embodiments, the main unlocking device further includes a plurality of unlocking switches 22 provided in one-to-one correspondence with each vehicle door Y. The main controller 21 is connected to each unlocking switch 22 to send an unlocking signal to the corresponding unlocking switch 22. The unlocking switch 22 operates in response to the unlocking signal. The emergency unlocking device includes a plurality of emergency unlocking switches 17 provided in one-to-one correspondence with each vehicle door Y. When any one of the emergency unlocking switch 17 and the unlocking switch 22 operates, the corresponding vehicle door Y is unlocked.

[0071] As mentioned above, this will be able to further enhance the independence of the emergency unlocking device and reduce the possibility of the driver and passengers being trapped in the vehicle.

[0072] For the specific technical details of the emergency unlocking switch 17, reference can be made to the description of the relevant part above, and details will not be repeated here.

[0073] The unlocking switch 22 can be any one of the unlocking switches provided in the related art. The structures of the unlocking switch 22 and the emergency unlocking switch 17 can be the same or different, and no limitation is imposed thereon.

[0074] The embodiments of the present application further provide a vehicle, which includes the emergency unlocking device described in any one of the above embodiments. Or the unlocking system described in any one of the above embodiments.
