Vehicle power control unit

Abstract

A power supply control device for a vehicle, including a generator, a regulator, a storage battery, a diode, a pressure switch, a solenoid valve and an air bag; the air inlet of the solenoid valve communicates with the air bag, and the execution port of the solenoid valve communicates with the air control port of the pressure switch Connected; the output terminal of the regulator, the diode, the pressure switch and the battery are electrically connected in turn to form a loop; one end of the terminal K of the solenoid valve is electrically connected to the connection point between the positive pole of the output terminal of the regulator and the anode of the diode, and the wiring of the solenoid valve The other end of terminal K is electrically connected to the connection point between the negative pole of the battery and the negative pole of the output terminal of the regulator; when the terminal K of the solenoid valve is energized, the air inlet P of the solenoid valve communicates with the execution port A, and when the solenoid valve When the terminal K is de-energized, the actuator port A of the solenoid valve communicates with the air outlet T; when the air control port K of the pressure switch is fed with pressure gas, the pressure switch is closed. The invention can realize that the power switch can be automatically disconnected after the vehicle is turned off.

Description

Technical field [0001] The present invention relates to a vehicle, and particularly to a power supply control apparatus for a vehicle. Background technique [0002] Switching power supply control device of the vehicle power supply control apparatus of an engine starting system activation system for the gas are usually manual switch, such as the prior art vehicle Figure 5 Shown, comprising a generator 1, a controller 2, an input terminal electrically manual power switch 3 and the battery 4, a generator 2 connected to the regulator, the regulator output terminal 2, manual power switch 3 and the battery 4 are electrically connected sequentially and form a loop. When the vehicle is started, the input shaft 1 starts rotating the generator, the generator in the power generation state 1, manually by the driver manual power switch 3 is closed, the generator 1 to the battery 2 through the regulator 4 is charged. 4 the battery used to power the vehicle electrical system. like Image 6 , The...

AI Technical Summary

Problems solved by technology

The manual power switch 3 of this power supply control device cannot be disconnected automatically after the vehicle is turned off, so that the driver forgets to disconnect the manual power switch 3 and leaves the vehicle when the vehicle is turned off, and the storage battery 4 is still supplying power to electrical systems such as the single-chip microcomputer 20 of the vehicle. , not only wastes energy, but also causes the problem of battery 4 feeding, which affects the next start of the vehicle
