The invention discloses an automatic cut-off temperature adjusting device for a temperature controller of an air conditioner of a truck. The main design concept of the device is that a temperature acquisition circuit, a logic operation circuit, a load resistance switching circuit and a temperature controller for pre-calibrating a corresponding relation between an input load resistance value and a cut-off temperature construct a cut-off temperature self-adaptive adjustment mechanism of the temperature controller of the truck air conditioner, specifically, according to the acquired different environment temperatures, the temperature acquisition circuit outputs corresponding electric signals to the logic operation circuit, the logic operation circuit controls the load resistance switching circuit to convert different load resistors according to a preset logic rule and in combination with the electric signals input by the temperature acquisition circuit, and the temperature controller changes different preset cut-off temperatures according to the input load resistors. The cut-off temperature of the temperature controller is automatically adjusted through the environment temperature, the starting frequency of a compressor can be reduced under the condition that the environment temperature is low, and therefore the energy consumption of the truck air conditioner can be remarkably reduced.
