Description
【Technical field】
The utility model is related to the technical field of automobile air conditioner accessories, particularly a kind of new-energy automobile integral electric
Scroll compressor.
【Background technology】
In the air-conditioning refrigeration systems such as new-energy automobile, widely used is electric scroll formula compressor.In current whirlpool
In rotary compressor, equilibrium problem be always influence screw compressor a key factor, the equilibrium problem mainly due to
Orbiter is eccentrically rotated generation rotating inertia force, vibration of compressor；The axial gas power that compressed gas generates, leads to sound
What disk was separated and was generated；And the reasonable balance of axial gas power is the key that ensure volumetric efficiency, mechanical efficiency and adiabatic efficiency
Technology so the two power all must try to reliably balance, can balance rotating inertia force by way of adding Balance Iron,
But not smart at present for axial gas power and effective balance mode.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of new-energy automobile integral type electricity
Dynamic scroll compressor can lower the Fluid pressure for being introduced into back pressure cavity, prevent orbiter axial by reducing fluid flow rate
Play.
To achieve the above object, the utility model proposes a kind of new-energy automobile integral electric scroll compressor,

Capstan and fixed scroll, form discharge chamber between the protecgulum and fixed scroll, the shell is equipped with by the motor drive
Rotatable bent axle, the bent axle are extended in the mounting base and are connect with the orbiter, and the fixed scroll is located at
The top of orbiter, the fixed scroll and orbiter intermeshing and shape compression chamber, the orbiter and mounting base
Between form back pressure cavity, offer the circulation passage that one end is connected with the back pressure cavity on the fixed scroll, the circulation is logical
The other end in road is connected with the discharge chamber, is equipped in the circulation passage by discharge chamber to the drop of a diameter of gradual-enlargement type of back pressure cavity
Press chamber.
Preferably, the bent axle is connect through capacity eccentric bearing with the orbiter, it is equipped in the capacity eccentric bearing flat
Weigh block, and the balance weight is simultaneously connect with the bent axle.
Preferably, the exhaust outlet is connected with the discharge chamber, oil eliminator is equipped in the exhaust outlet.
Preferably, the protecgulum is spirally connected with shell and is fixed together.
The beneficial effects of the utility model：Compared with prior art, the utility model utilizes back pressure by setting back pressure cavity
The back pressure of intracavitary corrects the inclined play of orbiter, it is made to keep balance, using pressure letdown chamber is set in circulation passage, flows
Body circulates after channel, on the one hand can collide with vias inner walls and consume energy, so as to reduce fluid flow rate, reduces
The Fluid pressure size of back pressure cavity is introduced into, prevents the back pressure in back pressure cavity excessive so that between orbiter and fixed scroll
Friction and wear aggravation the problem of.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
