[0031] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0032] like Figures 1 to 2 As shown, the door unlocking system includes: a collision sensor 10; an airbag controller 20, which is electrically connected to the collision sensor 10 and has a control interface 201; and a door unlocking motor 30, which is electrically connected to the control interface 201. When the vehicle is hit by a collision, the collision sensor 10 sends a collision signal to the airbag controller 20, so that the airbag controller 20 receives the collision signal and controls the door unlocking motor 30 to operate, thereby unlocking the vehicle door.
[0033] In the embodiment of the present application, since the airbag controller 20 is electrically connected to the collision sensor 10, upon a vehicle collision, the collision sensor 10 transmits a collision signal to the airbag controller 20, which then receives the collision signal. Since the airbag controller 20 is provided with a control interface 201, and the door unlocking motor 30 is electrically connected to the control interface 201, upon receiving the collision signal, the airbag controller 20 controls the door unlocking motor 30 to operate, thereby unlocking the vehicle doors. That is, in the embodiment of the present application, by setting the collision sensor 10 to be electrically connected to the airbag controller 20, the control interface 201 on the airbag controller 20 is electrically connected to the door unlocking motor 30, so that once the vehicle collides, after the collision signal is transmitted to the airbag controller 20, the airbag controller 20 can directly control the door unlocking motor 30 to operate, so that the door unlocking motor 30 unlocks the vehicle door, ensuring that the vehicle door can be quickly opened after the vehicle collides, thereby reducing the potential danger to the occupants in the vehicle.
[0034] It should be noted that the door unlocking motor 30 is usually connected to the door lock of the vehicle door. After the door unlocking motor 30 is running, the door unlocking motor 30 can apply force to the door lock, thereby unlocking the door lock and opening the door.
[0035] In addition, the airbag control unit 20 may have a housing, and the control interface 201 may be provided on the housing.
[0036] Furthermore, in the related art, a vehicle's door unlocking system includes a collision sensor 10, an airbag controller 20, a vehicle controller, and a door unlocking motor 30. The collision sensor 10 is electrically connected to the airbag controller 20, which is in turn electrically connected to the vehicle controller, which is in turn electrically connected to the door unlocking motor 30. When a vehicle collision occurs, the collision sensor 10 transmits a collision signal to the airbag controller 20, which in turn transmits the collision signal to the vehicle controller. The vehicle controller then controls the door unlocking motor 30 to unlock the vehicle's doors. In other words, in the related art, once a vehicle collision occurs, the collision signal is transmitted along the following path: collision sensor 10 - airbag controller 20 - vehicle controller - door unlocking motor 30. This long transmission path causes the vehicle door to remain open for a longer period of time. In the embodiment of the present application, the collision sensor 10 is electrically connected to the airbag controller 20, and the control interface 201 on the airbag controller 20 is electrically connected to the door unlocking motor 30. Therefore, once the vehicle collides, after the collision signal is transmitted to the airbag controller 20, the airbag controller 20 can directly control the operation of the door unlocking motor 30. That is, in the embodiment of the present application, the path of collision signal transmission is: collision sensor 10-airbag controller 20-door unlocking motor 30. Therefore, in the embodiment of the present application, the path of collision signal transmission is shorter, so that the door is opened for a shorter time.
[0037] In addition, in some embodiments, the control interface 201 is used to output a 12V voltage; when the vehicle is hit, the airbag controller 20 provides a 12V voltage to the door unlocking motor 30 through the control interface 201, so that the door unlocking motor 30 unlocks the vehicle door.
[0038] Because the control interface 201 outputs a 12V voltage, once the vehicle is impacted, the collision sensor 10 transmits a collision signal to the airbag controller 20. The airbag controller 20 then provides a 12V voltage to the door unlocking motor 30 via the control interface 201. After receiving the 12V voltage, the door unlocking motor 30 can operate normally, thereby unlocking the vehicle door. Specifically, the 12V voltage output by the control interface 201 ensures that the output voltage is sufficient to operate the door unlocking motor 30, avoiding the problem of a low output voltage causing poor operation of the door unlocking motor 30 and difficulty unlocking the vehicle door, and avoiding the problem of a high output voltage causing a high voltage on the door unlocking motor 30 and shortening the service life of the door unlocking motor 30.
[0039] In addition, in some embodiments, the control interface 201 outputs a 12V voltage for a duration greater than or equal to 350 milliseconds.
[0040] With this configuration, once the vehicle is impacted, the collision sensor 10 transmits a collision signal to the airbag controller 20. The airbag controller 20 then provides a 12V voltage output duration of greater than or equal to 350 milliseconds to the door unlocking motor 30 via the control interface 201. This ensures that the door unlocking motor 30 has sufficient power supply duration, allowing the door unlocking motor 30 to operate for a sufficient time to open the vehicle door. Specifically, by configuring the control interface 201 to output a 12V voltage duration of greater than or equal to 350 milliseconds, the door unlocking motor 30 can effectively open the vehicle door in the event of a collision.
[0041] It should be noted that the output duration of the 12V voltage output by the control interface 201 can be set according to actual needs. For example, the output duration of the 12V voltage output by the control interface 201 is 350 milliseconds. For another example, the output duration of the 12V voltage output by the control interface 201 is 400 milliseconds. For another example, the output duration of the 12V voltage output by the control interface 201 is 420 milliseconds. This embodiment of the present application does not limit this.
[0042] In addition, in some embodiments, the average current of the electric energy output by the control interface 201 is 3A, and the maximum current of the electric energy output by the control interface 201 is 5A.
[0043] With this configuration, once the vehicle is impacted, the collision sensor 10 transmits a collision signal to the airbag controller 20. The airbag controller 20 then supplies a 12V voltage to the door unlocking motor 30 via the control interface 201. The maximum current of the 12V voltage is 5A, preventing excessive current from flowing into the door unlocking motor 30, which could cause the door unlocking motor 30 to malfunction. Furthermore, the average current is 3A, effectively ensuring the normal operation of the door unlocking motor 30 to open the vehicle door. Specifically, by setting the average current of the power output by the control interface 201 to 3A and the maximum current of the power output by the control interface 201 to 5A, the door unlocking motor 30 can be effectively ensured to open the vehicle door in the event of a vehicle collision.
[0044] In addition, in some embodiments, the door unlocking system may further include a battery 40; the battery 40 is electrically connected to the airbag controller 20; when the vehicle is hit by a collision, the airbag controller 20 transmits the electrical energy of the battery 40 to the door unlocking motor 30 through the control interface 201, so that the door unlocking motor 30 unlocks the vehicle door.
[0045] Because the battery 40 is electrically connected to the airbag controller 20, the power from the battery 40 can be transferred to the airbag controller 20. Consequently, if the vehicle is involved in a collision, the airbag controller 20 can transfer the power from the battery 40 to the door unlock motor 30 via the control interface 201. Upon receiving the power, the door unlock motor 30 can operate and unlock the vehicle doors. In the absence of a collision, the airbag controller 20 does not provide power to the door unlock motor 30, rendering the door unlock motor 30 inoperative. Furthermore, the power from the battery 40 is transferred to the airbag controller 20, ensuring its normal operation. In other words, by providing the battery 40, the battery 40 effectively provides power to both the airbag controller 20 and the door unlock motor 30, ensuring their effective operation.
[0046] It should be noted that, in the embodiment of the present application, the battery 40 may be a power battery pack in a vehicle. Of course, the battery 40 may also be a battery in the vehicle that provides electrical energy to a vehicle controller.
[0047] In addition, in some embodiments, a control circuit 21 is provided in the airbag controller 20, one end of the control circuit 21 is electrically connected to the control interface 201, and the other end of the control circuit 21 is electrically connected to the battery 40; when the vehicle is hit by a collision, the control circuit 21 transfers the electrical energy of the battery 40 to the control interface 201, and then transfers it to the door unlocking motor 30.
[0048] With this configuration, the electrical energy from the battery 40 can be transferred to the control circuit 21. Once the vehicle collides, the control circuit 21 can transfer the electrical energy from the battery 40 to the control interface 201, and then to the door unlocking motor 30, which can then unlock the door. The control circuit 21 can convert the electrical energy from the battery 40 to prevent the larger amount of electrical energy from the battery 40 from being directly transferred to the control interface 201, thereby preventing the door unlocking motor 30 from receiving excessive electrical energy. For example, if the electrical energy from the battery 40 is 50V, after this energy is transferred to the control circuit 21, the control circuit 21 converts the electrical energy from the battery 40 to 12V, so that the control interface 201 transfers the 12V power supply to the door unlocking motor 30. That is, by configuring the control circuit 21, it is possible to ensure that the electrical energy on the door unlocking motor 30 is compatible with the door unlocking motor 30, facilitating the door unlocking motor 30 to unlock the vehicle.
[0049] In addition, in some embodiments, the control circuit 21 includes a control switch 211 and a voltage regulator 212; the first end of the voltage regulator 212 is electrically connected to the battery 40, the second end of the voltage regulator 212 is electrically connected to the first end of the control switch 211, the second end of the control switch 211 is electrically connected to the control interface 201, and the voltage regulator 212 is used to adjust the voltage transmitted to the control switch 211, and the control switch 211 switches between an on state and an off state; in the event of a collision of the vehicle, the control switch 211 is in an on state, so that the electrical energy of the battery 40 is transmitted to the voltage regulator 212, and then transmitted to the control interface 201 through the control switch 211, so that the control interface 201 transmits the electrical energy to the door unlocking motor 30.
[0050] With this configuration, the electrical energy from the battery 40 can be transmitted to the voltage regulator 212, which can then adjust the voltage so that the voltage output by the voltage regulator 212 meets the voltage required by the door unlocking motor 30. The voltage regulator 212 can then transmit the adjusted voltage to the control switch 211. Consequently, once the vehicle crashes, the control switch 211 can be turned on, and the voltage adjusted by the voltage regulator 212 can be transmitted through the control switch 211 to the control interface 201, and then to the door unlocking motor 30. When the vehicle is not in a crash, the control switch 211 is turned off, and the electrical energy from the battery 40 cannot be transmitted to the door unlocking motor 30. In other words, by providing the voltage regulator 212 and the control switch 211, it can be ensured that, in the event of a crash, the voltage regulator 212 effectively adjusts the output voltage, and the control switch 211 is turned on, effectively ensuring that the voltage transmitted to the control interface 201 meets the voltage required by the door unlocking motor 30, thereby facilitating the door unlocking motor 30 to unlock the vehicle door.
[0051] It should be noted that the voltage regulator 212 can adjust its own output voltage so that the voltage transmitted to the control switch 211 is 12V, thereby ensuring that the voltage transmitted to the control interface 201 is 12V.
[0052] Of course, in the embodiment of the present application, the control circuit 21 may further include other components, and the embodiment of the present application does not limit the specific structure of the control circuit 21.
[0053] In addition, in the embodiment of the present application, the control switch 211 includes at least one of a relay and a MOS tube. Through such a configuration, the cost of the door unlocking system can be effectively reduced.
[0054] Additionally, in some embodiments, the control interface 201 and the door unlock motor 30 are connected via the vehicle's CAN line. This arrangement effectively connects both the control interface 201 and the door unlock motor 30 to the vehicle's CAN line, eliminating the need for additional cables to connect the control interface 201 and the door unlock motor 30, thereby enabling the sharing of the vehicle's CAN line. This ensures that the door unlock motor 30 rapidly unlocks the vehicle door after a collision and also eliminates the need for additional cables, thereby reducing costs.
[0055] In the embodiment of the present application, since the airbag controller 20 is electrically connected to the collision sensor 10, upon a vehicle collision, the collision sensor 10 transmits a collision signal to the airbag controller 20, which then receives the collision signal. Since the airbag controller 20 is provided with a control interface 201, and the door unlocking motor 30 is electrically connected to the control interface 201, upon receiving the collision signal, the airbag controller 20 controls the door unlocking motor 30 to operate, thereby unlocking the vehicle doors. That is, in the embodiment of the present application, by setting the collision sensor 10 to be electrically connected to the airbag controller 20, the control interface 201 on the airbag controller 20 is electrically connected to the door unlocking motor 30, so that once the vehicle collides, after the collision signal is transmitted to the airbag controller 20, the airbag controller 20 can directly control the door unlocking motor 30 to operate, so that the door unlocking motor 30 unlocks the vehicle door, ensuring that the vehicle door can be quickly opened after the vehicle collides, thereby reducing the potential danger to the occupants in the vehicle.
