[0047] In an optional embodiment, the shape of the first bracket 11 is consistent with the shape of the light guide 12. Figure 3 The light guide 12 and the first bracket 11 are shown as long strips. In actual applications, the shapes of the light guide 12 and the first bracket 11 can be adjusted according to needs. The contour line of one end surface of the first bracket 11 is consistent with the contour line of the light guide 12, so that the light guide 12 is placed on the first bracket 11; the other end surface of the first bracket 11 is provided with a clamping structure, and the first bracket 11 is clamped on the outer surface of the vehicle through the clamping structure, so that the light guide 12 is fixed on the outer surface of the vehicle.

[0048] In an optional embodiment, if Figure 3As shown, the first bracket 11 and the light guide 12 are respectively engaged with the first surface of the cover plate 13 , and the first surface of the cover plate 13 seals the light guide 12 and the first bracket 11 together from the sides of the light guide 12 and the first bracket 11 , further reinforcing the light guide 12 and the first bracket 11 .

[0049] In an optional embodiment, if Figure 3 As shown, the light prompt device also includes a harness 14, a circuit board 15 and a second bracket 16. One end of the light guide 12 passes through the cover plate 13 and is clamped on the second bracket 16, and the circuit board 15 is clamped on the second bracket 16. The light guide 12 and the circuit board 15 are connected through the harness 14, so that whether the light guide 12 emits light is controlled by the circuit board 15.

For example, when a pet is detected to be left in the vehicle, the color of the light prompt device is orange, and when a baby is detected to be left in the vehicle, the color of the light prompt device is red, etc.

[0052] In an optional embodiment, the prompt device 1 may also include a sound prompt device, which is used to issue a sound prompt based on the prompt instruction. The installation position of the sound prompt device may not be limited to the outer side of the vehicle, and it may be installed at any position outside the vehicle.

[0053] In an optional implementation, after receiving the prompt instruction, the sound prompt device responds to the prompt instruction and issues a sound warning.

[0054] In an optional implementation, after receiving the prompt instruction, the sound prompt device will make a sound warning according to the sound prompt information contained in the prompt instruction. The sound prompt information contained in the prompt instruction may include the information content or sound frequency of the sound warning issued by the sound prompt device, the time interval for issuing the sound warning, etc. At this time, different situations left in the car can be indicated by the information content of the sound warning and the frequency of issuing the sound warning. For example, when a pet is detected to be left in the car, the sound frequency issued by the sound prompt device is a first frequency, and when a baby is detected to be left in the car, the sound frequency issued by the sound prompt device is a second frequency; for another example, when a pet is detected to be left in the car, the sound prompt device issues a sound warning of "pet left in the car", and when a baby is detected to be left in the car, the sound prompt device issues a sound warning of "baby left in the car".

[0055] In an optional embodiment, the system further includes a controller, which is disposed inside the vehicle and connected to the detection device 2. The controller is used to detect the locked state of the vehicle, and send a biometric information detection instruction to the detection device 2 when the vehicle is detected to be in the locked state; correspondingly, the detection device 2 is used to detect the biometric information when receiving the biometric information detection instruction.

[0056] In an optional implementation, when a person in the vehicle gets out and locks the vehicle, it is determined that the vehicle is in a locked state. Considering that the vehicle is usually in a started state when there is someone in the vehicle but the doors are locked, it is possible to determine whether the person in the vehicle gets out and locks the vehicle by whether the vehicle is started and the doors are locked, thereby determining whether the vehicle is in a locked state, so as to avoid the vehicle left-behind reminder system from being mistakenly started when there is someone in the vehicle but the vehicle is locked, thereby improving the reliability of the vehicle left-behind reminder system.

[0057] In an optional embodiment, in order to reduce the number of devices in the vehicle, improve the integration of vehicle devices, and reduce the complexity of the vehicle circuit structure, the function of the controller can be implemented by the vehicle's body controller, which determines that the vehicle is in a locked state when signals of vehicle shutdown and door locking are detected.

[0058] In an optional embodiment, the vehicle legacy system may further include a switch, and the switch is used to activate the vehicle legacy reminder system. The vehicle user can choose whether to trigger the switch according to needs to determine whether to activate the vehicle legacy reminder system. Optionally, the switch can be set on the display screen of the vehicle in the form of a touch key, and the vehicle user can trigger or turn off the switch by interacting with the display screen of the vehicle. Optionally, the switch can be set in the vehicle in the form of a physical button, and the vehicle user can trigger or turn off the switch by interacting with the physical button.

[0059] In an optional embodiment, the detection device 2 is also used to detect biological information in the vehicle, and send a closing prompt instruction to the prompt device 1 when a signal indicating that there is no biological residue is detected, wherein the signal indicating that there is no biological residue is formed when the detection device 2 detects that there is no biological information in the vehicle, and is used to indicate that there is no biological residue in the vehicle. That is, after the vehicle user reopens the door, takes away the biological residue in the vehicle, and gets out of the vehicle and locks the vehicle again, a closing prompt instruction is sent to the prompt device 1, so that the prompt device 1 no longer indicates that there is a biological residue in the vehicle.

[0060] In an optional embodiment, when the detection device 2 detects that there is no biological residue signal and sends a closing prompt instruction to the prompt device 1, in the prompt device 1, the light prompt device is also used to turn off the light prompt based on the closing prompt instruction, and the sound prompt device is also used to turn off the sound prompt based on the closing prompt instruction.

[0061] In an optional embodiment, the detection device 2 may include a biological detection module and a control module. Among them, the controller, the biological detection module, the control module and the prompt device 1 are connected in sequence. The biological detection module and the control module are both arranged inside the vehicle. After receiving the biological information detection instruction sent by the controller, the biological detection module detects the biological information in the vehicle to confirm whether there is biological residue in the vehicle. When it is determined that there is biological residue in the vehicle, it generates a biological residue signal and sends the biological residue signal to the control module; the control module sends a prompt instruction to the prompt device 1 after receiving the biological residue signal. Similarly, when the biological detection module determines that there is no biological residue in the vehicle, it generates a no biological residue signal and sends a no biological residue signal to the control module; the control module sends a close prompt instruction to the prompt device 1 after receiving the no biological residue signal.

[0062] In an optional embodiment, the biological detection device 2 may be an infrared detector, which scans and detects the energy distribution in the vehicle to determine whether there are biological residues in the vehicle. The biological detection device 2 may also be an image sensor, which acquires and analyzes images in the vehicle to determine whether there are biological residues in the vehicle.

[0063] In an optional implementation, in order to reduce the number of components in the vehicle, improve the integration of vehicle components, and reduce the complexity of the vehicle circuit structure, the functions of the control module may be implemented by a vehicle cabin controller.

[0064] In an optional embodiment, Figure 4 This is a schematic diagram of the workflow of a vehicle left-behind reminder system provided by an embodiment of the present application. Figure 4 The working process of the vehicle legacy reminder system is further explained. Figure 4As shown, when the vehicle user gets off the vehicle and locks the vehicle, the controller, that is, the body controller detects that the vehicle is in a locked state, and sends a biological detection instruction to the biological detection module in the detection device 2, instructing the biological detection module to perform detection, and the biological detection module detects the biological information in the vehicle; if a biological legacy signal is detected, the biological detection module feeds back the biological legacy signal to the cockpit controller, and the cockpit controller sends a prompt instruction to the prompt device after receiving the biological legacy signal, instructing the prompt device to issue an instruction; after seeing the instruction issued by the prompt device, the vehicle user returns to the vehicle to take away the biological left in the vehicle, and when getting off the vehicle again and locking the vehicle, the controller detects that the vehicle is in a locked state, and sends a biological detection instruction to the biological detection module in the detection device 2, instructing the biological detection module to perform detection, and the biological detection module detects the biological information in the vehicle; if no biological legacy signal is detected at this time, the biological detection module feeds back the no biological legacy signal to the cockpit controller, and the cockpit controller sends a close prompt instruction to the prompt device after receiving the no biological legacy signal, instructing the prompt device to close the indication.
