[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a vehicle emergency door opening device, comprising a lock control system installed in the vehicle door, a handle switch 1 installed in the vehicle door for emergency door opening, and a hidden handle system installed on the vehicle door. The lock control system, the handle switch system, and the hidden handle system are connected by a wiring harness 11.

[0023] The lock control system includes a power supply device 2, a PCBA module 3, a door lock 4, a door lock motor 5 and a control harness 10. The control harness 10 is used to connect to the vehicle's electronic control system. The driving end of the door lock motor 5 is connected to the door lock 4. The door lock motor 5 is electrically connected to the power supply device 2, the PCBA module 3, the handle switch 1 and the control harness 10 respectively. The door lock motor 5 is used to drive the door lock 4 to move and open the vehicle door.

[0024] The hidden handle system includes a hidden handle 8 installed on the outside of the vehicle door and an actuator 9 installed inside the vehicle door. The driving end of the actuator 9 is connected to the hidden handle 8. The actuator 9 is electrically connected to the power supply device 2, the PCBA module 3, the handle switch 1 and the control harness 10 respectively. The actuator 9 is used to drive the hidden handle 8 to unfold from the vehicle door.

[0025] The handle switch 1 is embedded and installed on the inside of the vehicle door. The handle switch 1 is electrically connected to the PCBA module 3, the power supply device 2 and the control harness 10 in the vehicle door. When the handle switch 1 is in a closed state, the vehicle electronic control system is powered normally. When the handle switch 1 is pulled, the handle switch 1 is disconnected from the vehicle electronic control system, and the handle switch 1 is connected to the PCBA module 3 and the power supply device 2. The power supply device 2 supplies power to the door lock motor 5 and the actuator 9 respectively. The door lock motor 5 drives the door lock 4 to move to open the vehicle door, and the actuator 9 drives the hidden handle 8 to unfold from the vehicle door.

[0026] Specifically, the handle switch 1 is embedded in the interior of the vehicle door. The power supply 2, PCBA module 3, door lock motor 5, door lock 4, and control harness 10 are installed inside the vehicle door. The door lock 4 is fixed to the vehicle. The drive end of the door lock motor 5 is connected to the door lock 4. The door lock motor 5 is electrically connected to the power supply 2, PCBA module 3, handle switch 1, and control harness 10. The handle switch 1 is electrically connected to the power supply 2, PBCA board, and control harness 10. The control harness 10 is connected to the vehicle's electronic control system. A hidden handle 8 is installed on the exterior of the vehicle door. An actuator 9 is installed inside the vehicle door. The drive end of the actuator 9 is connected to the hidden handle 8. The actuator 9 is electrically connected to the power supply 2, PCBA module 3, handle switch 1, and control harness 10. When handle switch 1 is closed, the vehicle's electronic control system receives normal power. When handle switch 1 is toggled, it disconnects control harness 10 from the vehicle's electronic control system, connecting it to PCBA module 3 and power supply 2. Power supply 2 then supplies power to door lock motor 5 and actuator 9. Door lock motor 5 drives door lock 4 to release the vehicle, allowing the driver or passenger to open the door from inside. Actuator 9 deploys concealed handle 8 from the door, allowing rescuers to open the door from the outside.

[0027] In the above structure, by providing a handle switch 1 and a lock control system to unlock the vehicle door, the vehicle door can be quickly opened in an emergency, allowing the driver and passengers to leave the vehicle in time, thereby reducing safety hazards. In addition, by providing a hidden handle system, the hidden handle 8 can be quickly deployed from the vehicle door, making it easier for rescue personnel to open the vehicle door from the outside, greatly reducing the safety hazards of opening the vehicle door in an emergency.

[0028] like Figure 3 As shown, in one embodiment, the power supply device 2 of the vehicle emergency door opening device is a battery assembly. The battery assembly includes multiple batteries. When the battery is low on power, the battery can be replaced to maintain sufficient power. This configuration allows for convenient and quick battery replacement.
