[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The embodiment of the present application provides a vehicle ceiling light system, which can solve the technical problem in the related art that the lamp assembly integrated with the germicidal lamp usually has a larger volume and is difficult to install on the installation bracket welded on the roof cover with limited layout position.

[0034] See also Figure 1 and Figure 4 As shown, a vehicle ceiling light system provided by an embodiment of the present application may include: a vehicle ceiling light assembly, the vehicle ceiling light assembly includes a sunroof decorative cover 1 and a lamp body circuit board 2 installed on the sunroof decorative cover 1, the lamp body circuit board 2 is installed with a lighting lamp group 21 and a sterilizing lamp group 22 connected in parallel; a microcontroller, the microcontroller is electrically connected to the lighting lamp group 21 and the sterilizing lamp group 22 respectively, and the microcontroller is used to control the lighting lamp group 21 and / or the sterilizing lamp group 22 to turn on or off. The microcontroller can control the lighting lamp group 21 and the sterilizing lamp group 22 to turn on synchronously, or can control the lighting lamp group 21 to turn on separately, at which time the sterilizing lamp group 22 is turned off, or the sterilizing lamp group 22 is turned on, at which time the lighting lamp group 21 is turned off. In an embodiment of the present application, whether the lighting lamp group 21 and the sterilization lamp group 22 are turned on can be controlled by adjusting the lighting mode of the vehicle's lamp group. When the vehicle is in the lighting mode, the lighting lamp group 21 is turned on, and when it is in the sterilization mode, the sterilization lamp group 22 is turned on. The two modes can also be controlled to be turned on at the same time.

[0035] In the embodiment of the present application, the lamp body circuit board 2 with the lighting lamp group 21 and the germicidal lamp group 22 is installed on the sunroof decorative cover 1, and then the ceiling lamp cover 4 is installed on the sunroof decorative cover 1. The arrangement of the lighting lamp group 21 and the germicidal lamp group 22 can be realized by only installing the sunroof decorative cover 1 on the sunroof of the vehicle body. Specifically, the vehicle sunroof can be fixed to the vehicle body bracket by bolts, and an interior panel is installed under the sunroof body. The interior panel has been opened with a sunroof perforation according to the structure of the sunroof body. Therefore, the sunroof decorative cover with the lighting lamp group 21 and the germicidal lamp group 22 integrated therein is 1 can be directly installed on the sunroof body. In this process, the lamp body circuit board 2 with the lighting lamp group 21 and the germicidal lamp group 22 installed may not be directly connected to the vehicle body. Compared with the method of fixing the lighting lamp group 21 and the germicidal lamp group 22 on the mounting bracket welded on the roof cover after integration, the lighting lamp group 21 and the germicidal lamp group 22 in the embodiment of the present application can have a larger installation space, and during the installation process, the manufacturing deviation of the interior panel can also be ignored, reducing the assembly defect rate caused by the deviation between the hole position of the ceiling lamp mounting bracket and the interior panel. The technical problem that the lamp assembly with integrated germicidal lamps in the related art usually has a larger volume and is difficult to be installed on the mounting bracket welded on the roof cover with limited layout position is solved.

[0036] In some optional embodiments, the vehicle ceiling light system may further include: a video monitoring device, the video monitoring device is connected to the microcontroller signal, and the microcontroller is used to control the lighting lamp group 21 or the sterilization lamp group 22 to turn on or off according to the signal obtained by the video monitoring device. In the embodiment of the present application, the video monitoring device can be a camera of a fatigue monitoring device on the vehicle, and the distribution of personnel in the cab can be judged by the camera. When the camera captures that there are people in the cab, even if you want to turn on the sterilization mode of the vehicle, it will exit the sterilization mode due to insufficient conditions for turning on. Preferably, the sterilization lamp group 22 can use UVC-LED (ultraviolet C-segment light emitting diode). When working, UVC-LED can use the short-wave ultraviolet rays (UVC) emitted by ultraviolet LED to destroy the DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) structure of microorganisms, resulting in their inability to reproduce and grow, thereby achieving the purpose of disinfection and sterilization. However, it may cause harm to human eyes and skin during the sterilization process. Therefore, by setting a video monitoring device, it can effectively avoid UVC-LED from causing damage to the human body and enhance the safety of the sterilization process.

[0037] In some optional embodiments, the vehicle ceiling light system also includes an infrared temperature sensor, which is connected to the microcontroller signal. The microcontroller is used to control the sterilization lamp group 22 to turn on when it is detected that there is no one in the car and there is no object within the preset temperature in the car; and when it is detected that there is someone in the car or there is an object within the preset temperature in the car, the sterilization lamp group 22 is controlled to turn off. The infrared temperature sensor can detect the temperature distribution in the cab. In the embodiment of the present application, a preset temperature can be set. The preset temperature can be a range value, specifically 36 to 40°C. The temperature can be a temperature that simulates people and common pets. When the infrared temperature sensor senses that there is an object of about 36 to 40°C in the cab, even if the driver wants to turn on the sterilization mode, it will automatically exit the sterilization mode due to insufficient conditions for turning on. In some other embodiments, the preset temperature can also be set to a temperature in a larger range, such as 34 to 43°C. Furthermore, even if the sterilization mode of the vehicle is started, the microcontroller can also control whether the sterilization lamp group 22 is turned on according to the detection of personnel by the camera monitoring device and the detection of temperature distribution by the infrared temperature sensor, that is, the sterilization mode is turned on. When the camera detects that there is no one in the cab, and the infrared temperature sensor senses that there is no object in the temperature range of 36 to 40°C in the car, the microcontroller controls the sterilization lamp group 22 to turn on. If the camera detects that there is no one in the cab, but the infrared temperature sensor senses that there is an object in the temperature range of 36 to 40°C in the car, or the infrared temperature sensor senses that there is no object in the temperature range of 36 to 40°C in the car, but the camera detects that there is someone in the cab, the microcontroller controls the sterilization lamp group 22 to turn off. The camera monitoring device and the infrared temperature sensor can be regarded as a personnel monitoring and judgment module. By adding a personnel monitoring and judgment module to increase the opening conditions of the sterilization lamp group 22, the accuracy of the sterilization lamp group 22 in judging whether there is a person in the cab is enhanced, and by setting an infrared temperature sensor, pets can also be protected to a certain extent.

[0038] In some optional embodiments, the microcontroller is also signal-connected to a door status monitoring module, and the microcontroller is used to control the germicidal lamp group 22 to turn on when it is detected that the door is closed and there is no one in the car; and when it is detected that there is someone in the car or the door is open, the germicidal lamp group 22 is controlled to turn off. In the embodiment of the present application, the door status monitoring module can be a DCM (Door Control Module). For the sake of sterilization safety, the protection of the door status is added, that is, when the door status monitoring module detects that the door is closed and the camera monitoring device detects that there is no one in the car, the sterilization mode is turned on, and the germicidal lamp group 22 can be started normally. In the embodiment of the present application, the camera monitoring device, the infrared temperature sensor and the door status monitoring module cooperate to form multiple protections during the sterilization process. Specifically, when the door status monitoring module detects that the door is in a closed state, the camera monitoring device detects that there is no one in the car, and the infrared temperature sensor senses that there is no object in the temperature range of 36 to 40°C in the car, the sterilization mode is normally turned on and the germicidal lamp group 22 is turned on. When the door status monitoring module detects that the door is in the open state or the camera monitoring device detects that there is someone in the car, or the infrared temperature sensor senses that there is an object in the temperature range of 36 to 40°C in the car, the sterilization mode is exited and the sterilization lamp group 22 is turned off. Furthermore, when the status of each device or sensor in the vehicle meets the conditions for starting the sterilization mode, and the sterilization lamp group 22 is turned on and works normally, the door status monitoring module can also immediately exit the sterilization mode when it detects the opening and closing of the door, and the sterilization lamp group 22 is turned off. In the embodiment of the present application, by setting up multiple layers of protection, the possibility of the sterilization lamp group 22 irradiating the human body or pets during the vehicle sterilization process can be further reduced or avoided, and the UVC-LED can also have a good sterilization effect on the cab.

[0039] In some optional embodiments, the microcontroller signal is connected to a time monitoring module, and the microcontroller is used to control the germicidal lamp group 22 to continue to turn on for a preset time when it is detected that the car door is closed and there is no one in the car; when it is detected that the car door is open or there is someone in the car or the sterilization exceeds the preset time, the germicidal lamp group 22 is controlled to turn off. In the embodiment of the present application, the preset time can be set to 10 minutes. When the sterilization mode is normally turned on and the germicidal lamp group 22 is lit for one minute, the microcontroller can control the germicidal lamp group 22 to turn off, that is, exit the sterilization mode. Within the preset time, if a situation occurs that will cause the sterilization mode to exit, such as the car door is opened, the sterilization mode will exit. By setting the preset time, the germicidal lamp group 22 can automatically turn off after the time is reached without human control, reducing the process of repeated operations by personnel and enhancing the flexibility of the sterilization process. In some other embodiments, the preset time can also be set to be greater than 10 minutes.

[0040] Preferably, in addition to controlling the continuous lighting time of the germicidal lamp group 22 after being turned on, the time monitoring module can also control how long the germicidal lamp group 22 starts to light up after the germicidal mode is turned on. For example, after the germicidal mode is turned on for 1 minute, the microcontroller controls the germicidal lamp group 22 to light up.

[0041] In some optional embodiments, the vehicle ceiling light system further includes a sunlight and rain sensor, which is connected to the microcontroller signal, and the microcontroller is used to control the lighting group 21 to turn on when it is detected that the illumination value in the cab is less than a preset value. It should be understood that the sunlight and rain sensor can read the illumination value in the cab. In the embodiment of the present application, the vehicle can be set to an adaptive lighting mode. When the adaptive lighting mode of the vehicle is turned on, the sunlight and rain sensor can continuously read the illumination value in the cab. When the illumination value is less than the preset value, the microcontroller can control the lighting group 21 to light up so that the illumination value in the room reaches the preset value. Specifically, the preset value of the illumination value can be set to 150lx.

[0042] In some optional embodiments, the lamp body circuit board 2 may include a driver side lighting panel, a passenger side lighting panel, a rest area lighting panel and a front lighting panel; the driver side lighting panel, the passenger side lighting panel, the rest area lighting panel and the front lighting panel are all equipped with the lighting lamp group 21 and the germicidal lamp group 22, and the lighting lamp group 21 and the germicidal lamp group 22 of the driver side lighting panel, the passenger side lighting panel, the rest area lighting panel and the front lighting panel are independently connected to the microcontroller signal. The sunroof decorative cover 1 can be formed into an annular quadrilateral, and each side of the sunroof decorative cover 1 has a certain width in the horizontal direction. The middle part of the annular quadrilateral sunroof decorative cover 1 may have a square hole. At this time, the driver side lighting panel, the passenger side lighting panel, the rest area lighting panel and the front lighting panel may be arranged to surround the square hole. See Figure 1 As shown, the width of the driver side lighting panel, the passenger side lighting panel, the rest area lighting panel and the front lighting panel can be smaller than the width of each side of the sunroof decorative cover 1 in the horizontal direction. In this way, the driver side lighting area 31, the passenger side lighting area 32, the front lighting area 33 and the rest area lighting area 34 can be integrated into the vehicle ceiling light assembly, which saves the layout space in the vehicle to a certain extent, and compared with the previous separate arrangement of the driver side, passenger side, front of the cab and rest area lighting, this method can also increase the convenience of installation. In the embodiment of the present application, the driver side, passenger side, front of the cab and rest area lighting can all be controlled separately, and the germicidal lamp group 22 corresponding to each zone can also be controlled separately, but the lighting lamp group 21 in each zone can also be controlled to be fully lit with one button, and the germicidal lamp group 22 in each zone can also be controlled to be fully lit with one button.

[0043] See also Figure 2As shown, in the embodiment of the present application, the lamp body circuit board 2 can be a PCB circuit board, the lighting lamp group 21 and the sterilizing lamp group 22 are installed on the PCB circuit board, and after the PCB circuit board is installed on the skylight decorative cover 1, the ceiling lamp cover 4 is set on one side of the skylight decorative cover 1, and the ceiling lamp cover 4 and the skylight decorative cover 1 are embedded in each other, and both have a milky white appearance. A light diffuser is added to the ceiling lamp cover 4 to avoid appearance defects caused by protrusions. Figure 5 and Figure 6 As shown, during the assembly process, the PCB circuit board can be first fixed to the lamp slot corresponding to the sunroof decorative cover 1 by screws, and then the ceiling light cover 4 can be buckled onto the sunroof decorative cover 1 by using the buckle structure 5. The buckle structure 5 has a strong feedback sense during installation, and the feedback sense can ensure that the ceiling light cover 4 is assembled in place. Figure 3 As shown, after the ceiling light shade 4 and the skylight decorative cover 1 are installed, the skylight decorative cover 1 can be installed on the skylight frame 6 by bolts. After the installation is completed, the surrounding gap is checked to see if there are defects such as leaks.

[0044] In some optional embodiments, the vehicle's sunlight and rainfall sensors and video monitoring devices can also cooperate to identify the distribution of people in the cab through the camera of the video monitoring device. When the adaptive lighting mode is turned on, if the illumination value in the vehicle is less than 150lx, the microcontroller controls the lighting group 21 in the corresponding area according to the distribution of people in the cab until the illumination value in the cab reaches 150lx.

[0045] In some optional embodiments, the vehicle ceiling light system may further include a ceiling light control panel, the ceiling light control panel is connected to a vehicle body domain controller, the vehicle body domain controller is electrically connected to the microcontroller, and the vehicle body domain controller is used to send a control signal to the microcontroller so that the microcontroller controls the lighting lamp group 21 and / or the germicidal lamp group 22 to turn on or off. The ceiling light control panel may be integrated in the vehicle's central control screen. By setting the ceiling light control panel, the lighting lamp group 21 and the germicidal lamp group 22 may be controlled and adjusted by operating the ceiling light control panel. In addition, a voice control system may be set to control and adjust the lighting lamp group 21 and the germicidal lamp group 22 by voice. The processing controller in the embodiment of the present application may be an IDCU, and then the LIN (local interconnect network) signal is transmitted to the microcontroller inside the vehicle ceiling light assembly through the vehicle body domain controller (BCM) to respond to the corresponding mode; at the same time, the BCM can adjust the lit modules and the corresponding brightness according to the distribution of people in the cab in the adaptive lighting mode. For LIN communication, the length of the valid part of the data is 18, where data 1 represents the state of the driver's side lighting part, 00 is off, 01 is on, data 2 represents the brightness of the driver's side lighting part, where 0x0A represents the current 100% brightness value, and data 9 is the sterilization mode state, which has the highest priority. Figure 8 The LIN communication content shown means that the driver's side lighting mode of the ceiling light is turned on and is at the maximum brightness level, and the sterilization mode is not turned on at this time.

[0046] In the embodiment of the present application, the camera monitoring device and the infrared temperature sensor can be connected to the body domain controller through signals. The camera monitoring device obtains the distribution of personnel, and the infrared temperature sensor detects the temperature distribution in the cab; the door status monitoring module can be integrated in the body domain controller, and the door status monitoring module monitors the opening and closing status of the door and transmits it to the body domain controller. The body domain controller judges and decides whether to adjust the lighting group 21 and the sterilization lamp group 22 based on the obtained signals, and sends corresponding control instructions to the microcontroller, and the microcontroller performs corresponding operations based on the received instructions.

[0047] See also Figure 7As shown, the process of using the body domain controller to judge and control may include: if the driver wants to turn on all the lighting groups 21 for lighting, he can choose the full brightness mode. At this time, the central control screen is processed internally, and the status that the vehicle ceiling light assembly wants to respond to at this time is sent to the body domain controller BCM through the CAN (Controller Area Network) line, and then the BCM forwards it to the vehicle ceiling light assembly through the LIN line, and the vehicle ceiling light assembly responds according to the message. In full brightness mode, the status of the vehicle's ceiling light assembly can be memorized by the BCM. For example, if the gear position was 90% when it was last turned off, the brightness will still be 90% when it is turned on next time. The driver stops to rest at a service station. The environment is dark at this time. The driver turns on the adaptive lighting mode of the vehicle's ceiling light assembly. The sunlight and rainfall sensor reads that the illumination in the cab is less than 150lx at this time. At the same time, the camera of the video monitoring device detects that there is someone in the driver's seat and there is also a person on the berth. The BCM determines that the driver's side lighting module and the rest area lighting module corresponding to the ceiling light are lit, and gradually adjusts the brightness until the sensor detects that the indoor illumination value is greater than 150lx. At this time, the person in the rest area moves to the co-pilot seat to rest, and the corresponding rest area lighting module goes out, while the module corresponding to the co-pilot lighting is lit. The car is ready to start the sterilization mode. Before getting off the car, the sterilization mode is selected through the central control screen. At this time, the central control screen is processed internally, and the status of the vehicle ceiling light assembly to be responded to at this time is sent to the body domain controller BCM through the CAN line. Then BCM drives the cab camera monitoring device to work. After 1 minute of turning on, the camera first determines that there is no human activity in the cab, and at this time the infrared temperature sensor detects that there are no active organisms with a temperature of 37-40℃ in the cab. BCM comprehensively judges that there is no one in the cab. At this time, BCM forwards the LIN message to the ceiling light, and the UVC-LED starts working. It is expected to be turned off after 10 minutes. During this period, the cab camera monitoring device continues to work. When it detects that someone enters the cab, BCM receives the signal and forwards the message to the vehicle ceiling light assembly at the same time to turn off the sterilization mode.

[0048] The embodiment of the present application also provides a control method for the above-mentioned vehicle ceiling light system, and the control method may include: when the camera monitoring device detects that there is no one in the cab, controlling the germicidal lamp group 22 to turn on, and when the camera monitoring device detects that there is someone in the cab, controlling the germicidal lamp group 22 to turn off. That is, when the sterilization mode is turned on, the camera monitoring device monitors the distribution of people in the cab, and when it detects that there is no one in the cab, the microcontroller controls the germicidal lamp group 22 to turn on.

[0049] In the embodiment of the present application, the time monitoring module can also be integrated in the vehicle body domain controller. The specific process of turning on the sterilization mode can include first operating the ceiling light control panel or voice to turn on the sterilization mode. The central control screen voice prompts the driver and the people in the car to leave the cab and close the door. Then the time monitoring module integrated in the body domain controller starts timing for 1 minute. At this time, the DCM detects the opening and closing status of the door. If the door is closed, it goes to the next step. The BCM detects whether there is anyone in the cab through the camera of the camera monitoring device. If there is someone, the sterilization mode is exited at this time. This is the first line of protection; if the camera detects that there is no one, then the BCM drives the infrared temperature sensor to detect whether there is a biological organism at 36 to 40°C. If so, the sterilization mode is exited at this time. This is the second line of protection; if not, the sterilization lamp group 22 corresponding to the vehicle ceiling light assembly works. When the working time is less than 10 minutes, it continues to return to the DCM door status detection. If someone opens the door at this time, the sterilization function is immediately turned off. This is the third line of protection for detection. Because the camera and temperature sensor only detect the situation in the cab, the sterilization function is not turned off during the driver's getting on and off the car, which will also cause certain damage to the personnel. By setting the sterilization mode, the number of bacteria inside the vehicle can be significantly reduced through the sterilization lamp group 22, the air quality inside the vehicle can be improved, and a healthier and more comfortable riding environment can be provided for passengers. By setting three layers of protection, the sterilization lamp group 22 can be effectively prevented from directly irradiating the human body or pets, which may cause damage to the human body or pets, thereby enhancing the safety of the sterilization process.

[0050] The embodiment of the present application further provides a vehicle, which includes the vehicle roof light system as described above. The vehicle in the embodiment of the present application includes the vehicle roof light system in any of the above embodiments, which will not be described in detail here.
