Description

Technical Field

[0001] The utility model relates to a vehicle chassis power supply detection device. Background Art

[0002] Emergency rescue equipment, such as fire water tankers and power supply trucks, requires voltage status detection of the vehicle's DC power supply to prevent low voltage or excessive power consumption of the chassis battery, which may affect the vehicle's maneuverability.

[0003] At present, the existing power supply detection devices mostly use PLC integrated control detection, which has complex electrical principles and poor maintainability, affecting the mobility of emergency rescue equipment. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an automobile chassis power supply detection device which has a relatively simple electrical principle and good maintainability.

[0005] In order to solve the above technical problems, the utility model provides an automobile chassis power supply detection device, which has a chassis battery, the positive pole of the chassis battery is electrically connected to the chassis power main switch, the main power fuse and the main power switch in sequence, and is characterized in that it also includes a low voltage detector, one end of the low voltage detector is electrically connected to the negative pole of the chassis battery, and the other end is electrically connected to the monitoring device fuse and the monitoring device switch in sequence, and the monitoring device switch is electrically connected to the main power switch via a wire.

[0006] In this utility model, when the low-voltage detector detects that the chassis battery voltage is less than 19.2V, it indicates that the chassis battery is over-consumed and should be recharged promptly. This utility model uses only a few electronic components: a low-voltage detector, a monitoring device fuse, and a monitoring device switch to monitor the chassis battery voltage. The electrical principle is relatively simple and maintainability is relatively good.

[0007] Furthermore, the system includes a low-voltage buzzer. One end of the low-voltage detector is electrically connected to the low-voltage buzzer and the negative terminal of the chassis battery, respectively. When the voltage detected by the low-voltage detector is less than 19.2V, the low-voltage buzzer generates an audible and visual alarm. With the above technical features, the low-voltage buzzer automatically generates an audible and visual alarm when the voltage detected by the low-voltage detector is less than 19.2V, eliminating the need to regularly monitor the low-voltage detector's readings.

[0008] Furthermore, the system includes a chassis generator and a high-voltage detector. The chassis generator is connected in parallel with the chassis battery, and the high-voltage detector is connected in parallel with the low-voltage detector. With these technical features, the chassis generator can be tested for normal power generation. If the voltage detected by the low-voltage detector is less than 19.2V, it indicates that the chassis battery is consuming too much power and the chassis generator is not generating electricity. If the voltage detected by the high-voltage detector is less than 25.2V, it indicates that the chassis generator is not generating electricity and should be promptly repaired.

[0009] Furthermore, the system further includes a high-voltage buzzer. One end of the high-voltage detector is electrically connected to the high-voltage buzzer and the negative electrode of the chassis battery in sequence. The high-voltage buzzer is connected in parallel with the low-voltage detector. When the voltage detected by the high-voltage detector is less than 25.2V, the high-voltage buzzer generates an audible and visual alarm. With the above technical features, the high-voltage buzzer automatically generates an audible and visual alarm when the voltage detected by the high-voltage detector is less than 25.2V, eliminating the need to regularly monitor the detection value of the high-voltage detector.

[0010] Furthermore, a low-voltage buzzer is included. One end of the low-voltage detector is electrically connected to the low-voltage buzzer and the negative electrode of the chassis battery in sequence. The low-voltage buzzer is connected in parallel with the high-voltage buzzer and the high-voltage detector. When the voltage detected by the low-voltage detector is less than 19.2V, the low-voltage buzzer will sound an audible and visual alarm. With the above technical features, when the voltage detected by the high-voltage detector is less than 25.2V, the high-voltage buzzer will automatically sound an audible and visual alarm, eliminating the need to regularly monitor the high-voltage detector's detection value. When the voltage detected by the low-voltage detector is less than 19.2V, the low-voltage buzzer will automatically sound an audible and visual alarm, eliminating the need to regularly monitor the low-voltage detector's detection value.
