Because the engine rotates at a lower speed of about 2000 rpm under most working conditions, the rotating speed of the driving shaft of the compressor is relatively lower, while the rotating speed of the motor is relatively higher during electric driving, about 3000 rpm, under the working conditions of the same refrigerating capacity, the displacement of the compressor driven by the engine needs to be larger than that of the electric compressor. The existing vehicle-mounted air conditioner is to add a clutch and a belt pulley only on a driving shaft of an electric scroll compressor so as to select electric driving and engine driving. Under the condition that the electric driving condition meets the requirement of refrigerating capacity, the refrigerating capacity is obviously insufficient in engine working hours, and ideal air conditioning effect and experience effect are difficult to achieve. For this reason, improvements are required.

Disclosure of Invention

In order to achieve the above purpose, the present invention adopts the following technical solution.

An oil-electricity dual-purpose vehicle-mounted air conditioner compressor is formed by combining two scroll compressors and comprises an electric scroll compressor and a belt pulley scroll compressor, wherein driving shafts of the two compressors are independent and are respectively and correspondingly driven by a motor and an engine, and static scrolls of the two compressors are fixedly connected into a whole or are in an integral structure; the return air channels of the two compressors are communicated on the same return air port, the exhaust channels of the two compressors are converged in the same gas collecting cavity provided with an exhaust port, and the two exhaust channels are provided with one-way valves or one-way valve components.

The crankshaft adopting the technical scheme integrates the two scroll compressors, one is driven by the motor, the other is driven by the engine, the driving shafts of the two scroll compressors are in an independent state, and the two scroll compressors can work simultaneously or independently. When the motor-driven compressor displacement is designed to be smaller than the structure of the engine-driven compressor displacement, the refrigerating capacities of the motor-driven compressor and the engine-driven compressor can be basically equal, and the experience effect is improved under the condition of meeting the use requirement.

Preferably, the electric scroll compressor includes a first drive shaft, the first drive shaft being of unitary construction with the motor shaft. So that a compact and integrated electric scroll compressor is formed.

Preferably, the pulley scroll compressor includes a second drive shaft provided with a pulley via an electromagnetic clutch. The engine power is disconnected and connected with the second driving shaft through the separation and combination state of the electromagnetic clutch, and the start-stop control of the compressor is realized.

Preferably, a one-way valve membrane is arranged on the exhaust passage and is arranged on the end face of the outlet of the gas collection cavity of the exhaust passage. The structure of the check valve is simplified, the valve plate is opened under the impact of high-pressure gas, and the channel is closed under the action of elastic force, so that gas blowby at the high-pressure ends of the two compressors is avoided.

Preferably, the air return port is of a porous structure. The cross section of the air return channel is increased through a plurality of holes, the air return holes are conveniently arranged in a narrow zone, and the axial size of the compressor is favorably shortened when the air return holes are distributed along the circumferential direction.

Preferably, the two scroll compressors are coaxially arranged, and the gas collection cavity and the gas return port are both arranged on the assembly of the fixed scroll. The layout on the vehicle is convenient.

The beneficial effects of the utility model are that, have two kinds of power drive structures concurrently, and the two compressor function part that corresponds different parts can satisfy under normal operating mode, two compressor refrigerating output are the same basically, and user's experience is effectual.
