For reaching above-mentioned technical purpose, the embodiment of the present invention adopts following technological scheme:
A kind of rolling rotor type compressor, comprise electric machine assembly, pump assembly and housing, described electric machine assembly comprises stator, rotor and magnet ring; Described pump assembly comprises cylinder, bent axle, slide plate, upper flange and lower flange; Described stator to be positioned at above described cylinder and to be fixed on described housing, and described rotor is arranged on described cylinder interior, and described magnet ring and described rotor are fixed.
Wherein in an embodiment, described rotor is eccentric structure; The inner circle of described rotor and described cylinder concentric fits.
Wherein in an embodiment, described bent axle is sleeved in the inner circle of described rotor.
Wherein in an embodiment, the end face of described rotor is provided with circular groove, and described magnet ring is arranged in described circular groove.
Wherein in an embodiment, be interference fit between the circular groove of described rotor and described magnet ring.
Wherein in an embodiment, described magnet ring is bonded in the circular groove of described rotor by viscose.
Wherein in an embodiment, described upper flange is flat, and and forms confined space between the outer side wall of the end face of described cylinder and described magnet ring.
Wherein in an embodiment, described electric machine assembly is disk permanent-magnet dc motor.
Wherein in an embodiment, described stator is arranged in described housing by hot jacket or the mode of colding pressing.
Wherein in an embodiment, described pump assembly is fixed in described housing by three spot welding or six spot welding.
Rolling rotor type compressor provided by the invention, electric machine assembly and pump assembly are designed to integrated form, rotor by motor is assembled to pump assembly inside, and rotor instead of the roller in traditional compressor, achieves rotor and roller integration functionally; Thus greatly reduce the axial dimension of compressor, such that compressor is lightweight, volume is little, compact structure, be specially adapted to the strict restriction of occasion small-sized or microminiature refrigeration system etc. have to(for) installing space.

Embodiment
See Fig. 1 to Fig. 3, the invention provides a kind of rolling rotor type compressor, comprise electric machine assembly 100, pump assembly 200 and housing 300, electric machine assembly 100 comprises stator 110, rotor 120 and magnet ring 130, pump assembly 200 comprises cylinder 210, bent axle 220, slide plate 230, upper flange 240 and lower flange 250, stator 110 is positioned at the top of described cylinder 210 and is arranged on housing 300, and rotor 120 is arranged on the inside of cylinder 210, and magnet ring 130 is fixed with rotor 120; The sidewall that slide plate 230 is arranged on cylinder 210 contacts with the outer side wall of rotor 120.Upper flange 240 and lower flange 250 are arranged on the both sides of cylinder 210, for fixing cylinder; The outer side wall 122 of rotor 120 and the madial wall 212 of cylinder 210 form the sealed cavity 400 that a position constantly changes, and sealed cavity is divided into two-part by reciprocating slide plate 230.Preferably, sealed cavity 400 is crescent shape, and refrigeration working medium is compressed in crescent shape sealed cavity 400.Compressor provided by the invention, because rotor 120 is arranged on the inside of cylinder 210, greatly reduces the axial dimension of compressor, such that compressor is lightweight, volume is little, compact structure.
As a kind of embodiment, rotor 120 is eccentric structure, the inner circle of rotor 120 and cylinder 210 concentric fits.Eccentric rotor 120 instead of roller of the prior art, and forms closed cavity between cylinder, in order to compression refrigeration working medium.Preferably, bent axle 220 is sleeved in the inner circle of rotor 120, and this mode is assembled simply, can Direct driver bent axle during rotor turns, effectively make use of space simultaneously, is conducive to the miniaturization of compressor.
As a kind of embodiment, electric machine assembly 100 is disk permanent-magnet dc motor, and stator 110 and rotor 120 arrange for axially reciprocity and produce axial air-gap magnetic field.Disk permanent-magnet dc motor volume is little, and quality is light, has saved space, has reduced the volume of compressor.
As a kind of embodiment, magnet ring 130 is arranged on rotor 120 by circular groove 124, namely arranges at the end face of rotor 120 circular groove 124 matched with magnet ring 130, then is embedded wherein by magnet ring 130.This mode is easy to assembling, and has saved axial space, reduces the axial dimension of compressor.In order to the mechanical robustness between reinforcing member, circular groove 124 and magnet ring 130 closely can be combined by interference fit.In addition, magnet ring 130 can also be bonded in the circular groove 124 of described rotor by viscose.
Wherein in an embodiment, for ensureing the sealing of compressor, upper flange 240 design becomes slab construction.Form airtight space between the end face of this structure and cylinder 210 and the outer side wall of magnet ring 130, effectively prevent the leakage of refrigeration working medium.
As a kind of embodiment, stator 110 is arranged in housing 300 by hot jacket or the mode of colding pressing; Pump assembly 200 is fixed in housing 300 by three spot welding or six spot welding, and solder joint is positioned at the corresponding position of the outer side wall of cylinder 210 and the inwall of housing 300.The object keeping certain air gap between stator 110 and rotor 120 can be reached by the appropriate design of bond pad locations and hot jacket or height of colding pressing.
Rolling rotor type compressor provided by the invention, electric machine assembly and pump assembly are designed to integrated form, rotor by motor is assembled to pump assembly inside, and rotor instead of the roller in traditional compressor, achieves rotor and roller integration functionally; Thus greatly reduce the axial dimension of compressor, such that compressor is lightweight, volume is little, compact structure, be specially adapted to the strict restriction of occasion small-sized or microminiature refrigeration system etc. have to(for) installing space.
The above embodiment only have expressed several mode of execution of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
