Fig. 5 for the present invention in the first main support A-A to schematic diagram.Fig. 6 is Fig. 5 side view.Such as
Shown in Fig. 3 to 6, the connected mode of the first rear shell 8 and main support 6 in the present invention is as follows：Housing
8 inwall has three sections of join domains 62 and three provided with an annular inner shoulder table 81, the periphery of main support 6
Section avoids region 63, but is not limited.The annular of the join domain 62 of main support 6 and housing 8 is interior
The radial interference fit of shoulder 81, positions main support 6.Avoid between region 63 and annular inner shoulder table 81
It is collectively forming gap 13.The outer end of each join domain 62 has an arc surface of radial direction, whole circular arcs
The summation of central angle corresponding to face is less than 120 °.Referring to Fig. 5, the arc surface of three sections of join domains 62
Central angle e, f and g are corresponded to respectively, and central angle e, f and g angle are 25 °, the summation of three
For 75 °, but it is not limited.Moreover, join domain 62 is relative to the avoidance axial projections of region 63,
The annular inner shoulder table 81 of contact.The identical length of whole join domains 62 is same.And all avoid region 63
Identical length it is same.In other alternate embodiments, according to being actually needed that compressor is laid out, the present invention
In main support 6 can also have four sections, six sections, nine sections of join domains 62, between join domain 62
Spacing can also be unequal.
Fig. 7 for the present invention in second of rear shell A-A to schematic diagram.Fig. 8 is Fig. 7 side view.
Fig. 9 for the present invention in second of main support A-A to schematic diagram.Figure 10 is Fig. 9 side view.
As shown in Fig. 7 to 10, the connected mode of second of rear shell 8 and main support 6 in the present invention is as follows：
The periphery of main support 6 is provided with an outer shoulder 61 of annular, and the inwall of housing 8 is provided with three sections of join domains 82
With three sections of avoidance regions 83, the join domain 82 of housing 8 and the outer footpath of shoulder 61 of annular of main support 6
To interference fit, avoid and be collectively forming gap 13 between region 83 and the outer shoulder 61 of annular.Each connect
Connecing the outer end in region 82 has an arc surface of radial direction, the summation of the central angle corresponding to whole arc surfaces
Less than 120 °.Referring to Fig. 5, the arc surface of three sections of join domains 82 corresponds to central angle h, j and k respectively,
Central angle h, j and k angle are 25 °, and the summation of three is 75 °, but is not limited.And
And, join domain 82 contacts the outer shoulder 61 of annular relative to the axial projections of region 83 are avoided.All
The identical length of join domain 82 is same, and it is same all to avoid the identical length in region 83.In other changes
In embodiment, according to being actually needed that compressor is laid out, the rear shell 8 in the present invention can also have four sections,
Spacing between six sections, nine sections of join domains 82, join domain 82 can also be unequal.
Using main support and the spacing fixation of Al-alloy casing radial diameter in the present invention, what axial compressive force was fixed
Horizontal type scroll compressor (such as used in new energy vehicles electric scroll compressor), for example：In main support 6
3 sections or multistage (being more than 3 sections) arc surface cooperation fixation radially coordinated using being distributed on the face of cylinder,
Play fixation arc surface is less than total face of cylinder 1/3；3 sections of use point or multistage (are more than in the axial direction
3 sections) supporting surface support main support so that the area playing fixed supporting role is less than supporting surface correspondence annulus
1/3 (such as Fig. 5 and 7) of the area in face.Under conditions of intensity, firm requirement is met, main support 6
The area that is engaged between rear shell 8 is the smaller the better.The main support of this programme and the assembling structure of housing,
The contact area between main support and housing is effectively reduced, the passage of noise solid transmission is greatly reduced,
The noise being delivered to by main support solid outside compressor produced by parts such as base bearings is significantly reduced.
Main support coordinates fixed contact area small with Al-alloy casing, so that the solid transmission for reducing noise is logical
Road.
In summary, horizontal type scroll compressor of the invention can effectively reduce main support and Al-alloy casing
Coordinate fixed contact area, so as to reduce the solid transmission channels of noise.
It the above is only the concrete application example of the present invention, do not constitute any limit to protection scope of the present invention
System.In addition to the implementation, the present invention can also have other embodiment.All use equivalent substitutions are waited
The technical scheme that effect conversion is formed, all falls within scope of the present invention.
