[0028] The technical solution of the present invention can select the appropriate power type from AC and DC for power supply through the current selection component. It ensures that the vehicle power system can still operate stably in complex and changeable environments and when connecting devices of different power, and can improve the adaptability and reliability of the distribution module.

In addition, the setting of the AC lighting circuit breaker 22 and the DC lighting circuit breaker 32 provides the necessary overload and short-circuit protection for the distribution module, prevents power system failures from causing damage to other components of the vehicle, and improves the safety and reliability of the overall power system. It should be noted that the distribution module in the present invention can be used in distribution boxes and other equipment that requires power distribution.

[0029] In one embodiment, the first light group power supply line 41 is electrically connected to the air defense light module, and the second light group power supply line 42 is electrically connected to the lighting light module. Furthermore, the power supply selection component includes a first switch, a power switch and a door sensor receiving device, the receiving end of the power switch is electrically connected to the first switch and the door sensor receiving device, and the output end of the power switch is electrically connected to the first light group power supply line 41 and the second light group power supply line 42. When the first switch is turned on and the door sensor receiving device receives a signal from the door sensor sensing that the door is open, the power switch controls the second light group power supply line 42 to be energized. When the first switch is not turned on, or the door sensor receiving device does not receive a signal from the door sensor sensing that the door is open, the power switch controls the first light group power supply line 41 to be energized. That is, the first switch controls the color of the lighting module. When the first switch is turned on, the lighting module is automatically switched to the air defense light module according to the opening and closing state of the door to enhance the warning effect. When the first switch is turned off, all lighting modules are restored to ensure the normal lighting needs of daily operations. Generally speaking, the power of the air defense light module is relatively high. The linkage design of the first switch and the opening and closing of the door reduces the complexity of manual operation and avoids unnecessary energy waste. In other embodiments, the power supply selection component may not include the first switch, that is, when the door sensor receiving device receives the signal that the door sensor senses the door is open, the power switch controls the power supply line 42 of the second light group to be energized.

[0030] In one embodiment, the lighting power supply assembly 400 also includes a second switch, and the second switch is electrically connected to the receiving end of the power supply switch.

That is, when the second switch and the first switch are in the on state at the same time, and the door sensor receiving device receives the signal that the door sensor senses the door is open, the air defense light module will be energized to alert the person who opens the door. The provision of the second switch enables the operator to manually control the opening and closing of the lighting system in the car to avoid wasting energy when the car is not in use. In other embodiments, the second switch may not be provided.

First, an opening signal is sent through the second external button 447, and the second external button 447 triggers the second trigger. The second trigger is closed, indicating that the lighting mode is activated; then an opening signal is sent through the first external button 442, and the first external button 442 triggers the first trigger. The first trigger is closed, indicating that the air defense mode is activated, and the door sensor detects the open or closed state of the door and sends a corresponding signal to the signal processor 445. The signal processor 445 receives the door open signal, processes it, and then passes the signal to the signal trigger. The signal trigger determines that the first switch is on according to the current air defense mode state, so it passes the signal to the power supply switch to enable the second light group power supply line 42 to obtain power supply, and the air defense light module is on; the signal processor 445 receives the door closed signal and passes it to the signal trigger The first switch is identified as on, so a signal is transmitted to the power switch, so that the first light group power supply line 41 is supplied with power, and the lighting module is lit; a shutdown signal is sent through the first external button 442, and the first external button 442 triggers the first trigger, and the first trigger is disconnected, indicating that the air defense mode is canceled, and the door sensor still detects the open or closed state of the door, and transmits the signal to the signal processor 445. Regardless of whether the door is open or closed, the signal processor 445 transmits the signal to the signal trigger, and the signal trigger identifies that the first switch is closed, and transmits the signal to the power switch, so that the first light group power supply line 41 is supplied with power; a shutdown signal is sent through the second external button 447, and the second external button 447 triggers the second trigger, and the second trigger is disconnected, and the lighting module is turned off. That is, the second external button 447 controls the opening and disconnection of the second trigger, and then controls the state of the lighting in the compartment. When the air defense mode is turned on, the signal trigger automatically controls the second trigger according to the state of the door, ensuring that the air defense light module or the lighting light module can be correctly switched, and improving the intelligent level of the power distribution system in the power distribution module. The second external button 447 and the first external button 442 provide manual control options to meet the user's independent needs for lighting.
