[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] Please provide Chinese explanations for the following terms: 1. ECU (Electronic Control Unit); 2. PU (Polyurethane Material); 3. PDLC (Polymer Dispersed Liquid Crystal).

[0019] Please refer to Figures 1 to 6As shown, a sunroof intelligent safety response device includes: a sunroof assembly 1, a power supply 7, a pressure sensor 4, a water level sensor 3, an ECU 2, and a light-emitting device; the pressure sensor 4, the water level sensor 3, and the ECU 2 are distributed within a PU edging 5 and are electrically connected to the power supply 7 via a wiring harness 9; the light-emitting device is disposed inside the sunroof assembly 1 and is electrically connected to the power supply 7 via a power connection line 8.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: when the vehicle falls into the water, the water pressure sends an electrical signal to the pressure sensor 4, and the ECU2 determines whether water pressure is generated. At the same time, multiple water level sensors 3 form a multi-point detection to detect whether water level changes are detected in multiple places in the vehicle space. Only when the above requirements are met will the system determine that the vehicle has fallen into the water. Subsequently, the system starts working, and the power supply 7 is turned on to power the light-emitting device, providing intuitive visual guidance and attracting the attention of passers-by. In turbid water, it can indicate the location of the sunroof, making it easier to escape.

[0021] Furthermore, there are at least three water level sensors 3.

[0022] As described above, multiple water level sensors 3 form a multi-point detection system to prevent accidental activation of the system when the vehicle leaks water during car washing or rain.

[0023] Furthermore, the power supply 7 is a replaceable disposable power supply.

[0024] As described above, power supply 7 is a replaceable disposable power supply, which ensures that it occupies little space and can work independently, and can be used normally when the car battery fails.

[0025] Furthermore, the lead wires of the wiring harness 9 and the PU edging 5 are provided with tapered sealing plugs 10 at their outlet positions where they connect to the vehicle body.

[0026] As described above, after water enters the vehicle, the sealing plug 10 forms a sealed space, blocking the water flow and affecting the system's operation.

[0027] Furthermore, the light-emitting device includes a transparent light strip 6, which contains red LED beads.

[0028] As described above, the use of red LED beads in the transparent light strip 6 can maximize the alertness of people inside and outside the vehicle.

[0029] Furthermore, the transparent light strip 6 is made of transparent waterproof plastic material.

[0030] As described above, the transparent light strip 6 is made of transparent waterproof plastic material, ensuring that the transparent light strip 6 can work normally even if water enters the vehicle.

[0031] Furthermore, the transparent light strip 6 is adhered to the inner periphery of the sunroof assembly 1 using 3M adhesive.

[0032] As can be seen from the above description, the transparent light strip 6 is prevented from falling off by being bonded with 3M adhesive.

[0033] Furthermore, the power supply 7 supplies power to the red LED beads, causing the red LED beads to flash at a high frequency.

[0034] As described above, the red LED beads flash at high frequency to guide passengers to quickly find the escape direction, effectively increasing their chances of survival.

[0035] Furthermore, the light-emitting device is a colored PDLC film 11.

[0036] Furthermore, the colored PDLC diaphragm 11 is connected to the sunroof assembly 1 via the PDLC interface 12.

[0037] As can be seen from the above description, colored PDLC films can be used to replace red LED beads.

[0038] Please refer to Figures 1 to 5 As shown, Embodiment 1 of this utility model is as follows: A sunroof intelligent safety response device includes: a sunroof assembly 1, a power supply 7, a pressure sensor 4, a water level sensor 3, an ECU 2, and a light-emitting device. The pressure sensor 4, the water level sensor 3, and the ECU 2 are distributed within a PU edging 5 and are electrically connected to the power supply 7 via a wiring harness 9. The light-emitting device is located inside the sunroof assembly 1 and is electrically connected to the power supply 7 via a power connection line 8. There are at least three water level sensors 3. The power supply 7 uses a replaceable disposable power supply. The wiring harness 9 and the lead wires of the PU edging 5 have tapered sealing plugs 10 at their outlet positions where they connect to the vehicle body. The light-emitting device includes a transparent light strip 6 containing red LED beads. The transparent light strip 6 is made of transparent waterproof plastic and is adhered to the inner periphery of the sunroof assembly 1 with 3M adhesive. The power supply 7 supplies power to the red LED beads, causing them to flash at a high frequency. Thus, the frame formed by the LED light-emitting device on the sunroof can also flash to simulate gamified interaction, helping to alleviate passenger panic.

[0039] Please refer to Figures 1 to 6 As shown, Embodiment 2 of this utility model is as follows: The difference between Embodiment 2 and Embodiment 1 is only that: the light-emitting device is a colored PDLC film 11, and the colored PDLC film is connected to the sunroof assembly 1 through the PDLC interface 12.

[0040] Working principle: When the vehicle falls into the water, the pressure sensor 4 senses the water pressure and sends an electrical signal to the ECU2 through the wiring harness 9. The ECU2 then begins to respond and make a judgment. At the same time, if the water level sensor 3 detects a change in the water level, it sends an electrical signal to the ECU2 through the wiring harness 9. The ECU2 then begins to respond and make a judgment. The system will only determine that the vehicle has fallen into the water when at least three water level sensors 3 transmit electrical signals. At this time, the system starts to work, and the control power supply 7 supplies power to the light-emitting device through the power connection line 8, causing the light-emitting device to flash at a high frequency.

[0041] This solution is not limited to sunroofs; it can be extended to any car window, including the windshield, rear windshield, door windows, side windows, and corner windows.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
