A vehicle-mounted heat pump air-conditioning system capable of adjusting heat regeneration capacity is characterized in that a refrigerant loop and a secondary refrigerant loop exchange heat through a plate heat exchanger, an exhaust port of a refrigerant loop compressor is connected with an inlet of a front-end cooling module condenser, and an outlet of the condenser is connected with a high-pressure side inlet of a heat regenerator; a high-pressure side outlet of the heat regenerator is connected with a first inlet of the plate heat exchanger through the electronic expansion valve, a first outlet of the plate heat exchanger is connected with a first port of the proportioning valve, a second port of the proportioning valve is connected with a low-pressure side inlet of the heat regenerator, a low-pressure side outlet of the heat regenerator is connected with an air inlet of the compressor, and a third port of the proportioning valve is connected with the air inlet of the compressor. A second temperature and pressure sensor is arranged at an exhaust port of the compressor, a temperature sensor is arranged on the vehicle body, and the second temperature and pressure sensor and the temperature sensor collect temperature signals and send the temperature signals to the heat management system controller to adjust the proportion adjusting valve. The other end of the water pump is connected with a cold air core of the air-conditioning box assembly and then connected with a second inlet of the plate heat exchanger.
