[0038] The cavity 5 is provided with a first fixing seat 6 and a second fixing seat 7, which are used to fix the compressor housing 1 and the base plate 2. A first sealing portion 8 and a second sealing portion 9 are provided between the compressor housing 1 and the base plate 2 for sealing the compressor base.

[0039] By means of the above structure, the scroll compressor base in the embodiment of the present application can provide more effective support for the base plate 2 by setting a second fixed seat 7, and can divide the base plate 2, thereby changing the large plane integrated structure of the base plate 2, reducing resonance, thereby reducing vibration, and improving the stability of the installation of the base plate 2. In addition, by adding a second sealing portion 9, the overall strength and sealing effect of the sealing structure can be improved, thereby improving the safety of the control components in the cavity 5.

[0040] Reference Figure 1As shown, the present application shows a schematic diagram of the back plate structure of a scroll compressor. The back plate 3 is arranged at the bottom of the compressor housing 1, and the frame 4 is arranged around the back plate 3. The frame 4 is a part of the compressor housing 1 arranged around the bottom of the housing. Figure 1 As shown, the present application shows a structure of a frame 4, wherein the upper portion of the frame 4 is a rectangular structure, and the lower portion is a U-shaped structure, and the upper portion and the lower portion of the frame 4 are an integrated structure.

[0041] The bottom plate 2, the back plate 3 and the frame 4 form a cavity 5, and the cavity 5 is used to accommodate the controller and the fixing mechanism, and the fixing mechanism includes a first fixing seat 6 and a second fixing seat 7, and also includes a fixing member 12 connecting the bottom plate 2 and the back plate 3. In a possible implementation, the fixing member 12 is a mounting bolt.

[0042] like Figure 1 As shown, the first fixing seat 6 is arranged at the edge of the back plate 3, one end face of the first fixing seat 6 is connected to the back plate 3, and the other end face extends toward the bottom plate 2 to form a raised columnar structure, preferably, the columnar structure is a cylindrical structure. When the compressor housing 1 and the bottom plate 2 are fixed by the first fixing seat 6, the first fixing seat 6 abuts against the bottom plate 2 through the first sealing portion 8. The degree of abutment refers to the degree to which the first fixing seat 6 can abut against the bottom plate 2 through the first sealing portion 8 when the compressor housing 1 and the bottom plate 2 are fixed.

[0043] A second fixing seat 7 is installed on the central axis of the back plate 3, one end face of the second fixing seat 7 is connected to the back plate 3, and the other end face extends toward the bottom plate 2 to form a raised columnar structure, preferably, the columnar structure is a cylindrical structure. When the compressor housing 1 and the bottom plate 2 are fixed by the second fixing seat 7, the second fixing seat 7 abuts against the bottom plate 2 through the second sealing portion 9. The degree of abutment refers to the degree to which the second fixing seat 7 can abut against the bottom plate 2 through the second sealing portion 9 when the compressor housing 1 and the bottom plate 2 are fixed.

[0044] In some possible embodiments, the second fixing seat 7 installed on the back plate 3 can also be arranged at other positions of the back plate 3, and the position of the setting needs to avoid the controller and other components in the cavity 5. In addition, in order to improve the stability of the installation of the bottom plate 2, multiple second fixing seats 7 can also be installed on the back plate 3, which will not be described in detail in this application.

[0045] When the second fixing seat 7 is installed on the back plate 3, a mounting hole 11 is correspondingly opened on the bottom plate 2, and the mounting hole 11 corresponds to the position of the second fixing seat 7, so that the fixing member 12 passes through the mounting hole 11 on the bottom plate 2 to fix the bottom plate 2 and the back plate 3. Figure 2 As shown, a mounting hole 11 is opened on the central axis of the base plate 2 , and the mounting hole 11 corresponds to the position of the second fixing seat 7 .

The second sealing portion 9 is arranged at the position where the upper and lower parts of the frame 4 are connected, and is a horizontal strip structure. The first sealing portion 8 and the second sealing portion 9 are an integrated structure, which can improve the overall stability of the sealing structure.

[0048] A sealing ring 10 is formed on the second sealing portion 9, and the sealing ring 10 is configured as a circular through-hole structure, so that the fixing member 12 passes through the bottom plate 2, the sealing ring 10 and the second fixing seat 7, and fixes the bottom plate 2 and the back plate 3. The sealing ring 10 is arranged on the central axis of the second sealing portion 9, and can completely cover the second fixing seat 7 to seal the second fixing seat 7. The second sealing portion 9 extends to both sides along the sealing ring 10, and the extension direction is perpendicular to the central axis of the bottom plate 2, and both sides of the second sealing portion 9 extend to connect with the two sides of the first sealing portion 8. In some possible embodiments, the two sides where the second sealing portion 9 is connected to the first sealing portion 8 are two adjacent sides of the first sealing portion 8, or two opposite sides.

[0049] In some possible embodiments, when the extension direction of both sides of the second sealing portion 9 is perpendicular to the central axis of the bottom plate 2, the second sealing portion 9 can also be set at multiple positions connected to the two sides of the first sealing portion 8 according to the position of the second fixing seat 7. According to the position of the second fixing seat 7, the sealing ring 10 can be set at any position on the second sealing portion 9, and the arbitrary position can include but is not limited to the central axis position of the second sealing portion 9. In order to improve the stability of the installation of the bottom plate 2, multiple sealing rings 10 can be formed on the second sealing portion 9 on the premise of installing multiple second fixing seats 7 on the back plate 3, which is not described in detail in this application.

[0050] In some possible embodiments, the extension direction of the second sealing portion 9 to both sides may not be perpendicular to the central axis of the bottom plate 2, as long as the second sealing portion 9 is connected to the two sides of the first sealing portion 8, and the sealing ring 10 on the second sealing portion 9 at least partially covers the second fixing seat 7, the position of the second sealing portion 9 can be set arbitrarily. In addition, in order to improve the stability of the installation of the bottom plate 2, multiple second sealing portions 9 can also be set on the premise of installing multiple second fixing seats 7 on the back plate 3, which will not be described in detail in this application.
