A vehicle power supply automatic switching device comprises a box body, an input socket, an output socket, an alternating current contactor, a vehicle generating set power supply and an under-vehicle generating set power supply. The vehicle generating set power supply and the under-vehicle generating set power supply are connected with a normally-closed contact set and a normally-opened contact set of the alternating current contactor through the input socket respectively. A solenoid of the alternating current contactor is powered by the under-vehicle generating set power supply. A magnetic force generated after the solenoid of the alternating current contactor is powered on achieves power supply switching of the two power supplies. The output socket is electrically connected with vehicle electric equipment. The vehicle power supply automatic switching device is simple in structure and convenient to use, and achieves automatic switching between the vehicle generating set power supply and the under-vehicle generating set power supply by additionally provided with the alternating current contactor in a power supply loop, so that damage to the input socket in the power supply switching process is reduced, and the service life of a vehicle power supply system is prolonged.
