The utility model uses industry AC motor commonly used to replace the dc brushless motor that electric vehicle air condition compressor commonly used uses, and by compressor externally controlled type commonly used or internal control formula control mode compressor displacement is controlled.Simultaneously, the present invention is not limited to use the control mode of variable displacement automobile air-conditioning compressor that motor compressor is controlled, and can use frequency variator that the power supply of input AC motor is controlled, thereby changes the purpose that motor speed reaches the control compressor displacement.
Description of drawings
The above and other feature of the present utility model, character and advantage will become more obvious by the description below in conjunction with drawings and Examples, in the accompanying drawings, identical reference character is represented identical feature all the time, wherein:
Fig. 1 is the sectional view of the electric vehicle air condition compressor in the conventional art;
Fig. 2 is the sectional view of electric vehicle air condition compressor of the present utility model.
Embodiment
The utility model adopts dc brushless motor and the scroll compressor in threephase asynchronous machine and the externally controlled type variable compressor replacement conventional art.
The precondition that threephase asynchronous will rotate is to have a rotating magnetic field, and the staor winding of threephase asynchronous is used for producing rotating magnetic field.Phase power supply voltage between phase and phase differs 120 degree on phase place, also mutual deviation 120 degree on dimensional orientation of three windings in the threephase asynchronous stator, like this, when feeding the threephase AC of constant frequency in staor winding, staor winding will produce a rotating magnetic field and drive the compressor rotation.Thereby change discharge capacity air condition compressor commonly used can change the purpose that the open angle of swash plate reaches the control compressor displacement by the air-breathing exhaust pressure of compressor.Therefore, the present invention can simplify the control mode of automobile air conditioner compressor greatly, simultaneously owing to need not controller control also reduce the exploitation manufacturing expense of controller, thereby has reduced cost.
Fig. 2 shows the sectional view into electric vehicle air condition compressor of the present utility model.
As shown in Figure 2, the motor of electric air-conditioning compressor is a threephase asynchronous machine in the utility model, provides machine operation required power supply by three phase mains 11, thereby makes staor winding 12 produce rotating magnetic field.Under the effect of rotating magnetic field, make cage-type rotor sliver 18 cutting magnetic lines produce electric current.Cage-type rotor 13 is because the effect of electromagnetic force begins to rotate and drive the main shaft 14 that is fastened in it rotates together, and rotation speed n is less than the rotating magnetic field rotation speed n
0 Main shaft 14 links together with the swash plate 15 of compressor, and swash plate 15 moves in a circle under the effect of main shaft 14, makes the piston 16 beginning to-and-fro motion that are connected on the swash plate 15, thereby plays the effect that low pressure refrigerant gas is compressed into pressurized gas.Simultaneously, compressor has adopted externally controlled type electrically-controlled valve 17, can adjust the angle of compressor slanting plate by air-breathing exhaust pressure size, thereby effectively control the discharge capacity of whole air condition compressor.
As mentioned above, the present invention does not use extra dsp controller that compressor is controlled, but has adopted the controlling method of variable displacement automobile air-conditioning compressor commonly used, has reduced the exploitation manufacturing expense of controller, reduce cost, also simplified the control mode of motor compressor simultaneously.
The utility model uses industry AC motor commonly used to replace the dc brushless motor that electric vehicle air condition compressor commonly used uses, and by compressor externally controlled type commonly used or internal control formula control mode compressor displacement is controlled.Simultaneously, the present invention is not limited to use the control mode of variable displacement automobile air-conditioning compressor that motor compressor is controlled, and can use frequency variator that the power supply of input AC motor is controlled, thereby changes the purpose that motor speed reaches the control compressor displacement.
