As shown in fig. 1 and fig. 2, the present embodiment provides a compressor, which includes a compressor main body 10, an accumulator 20 and a connecting bracket 30, wherein the compressor main body 10 is communicated with the accumulator 20 through a compressor suction port 13, and the compressor main body 10 is connected with the accumulator 20 through the connecting bracket 30; the compressor main body 10 has a first top end surface 11 far away from the compressor suction port 13 along the self axial direction, and the liquid accumulator 20 has a second top end surface 21 far away from the compressor suction port 13 along the self axial direction; the connecting bracket 30 includes a first connecting portion 31 connected to the first tip end surface 11, a second connecting portion 32 connected to the second tip end surface 21, and transition portions 33 respectively connecting the first connecting portion 31 and the second connecting portion 32. In an exemplary embodiment, the compressor body 10 and the accumulator 20 are each a cylinder; the first connecting portion 31 is fixedly connected to the first top end surface 11, and the first connecting portion 31 is fixedly connected to the second top end surface 21, for example, by welding, so that the compressor body 10 and the liquid reservoir 20 are connected more firmly by the connecting bracket 30. Further, referring to fig. 5, the first connecting portion 31 has at least two positioning protrusions 311 on the side facing the first top end surface 11 of the compressor body 10, the positioning protrusions 311 are used for connecting with the first top end surface 11, and preferably, the positioning protrusions 311 are connected with the first top end surface 11 by pressure welding. In the compressor as described above, the connecting bracket 30 is provided to connect the compressor main body 10 and the accumulator 20 to fix them, and the first connecting portion 31 of the connecting bracket 30 is connected to the first top end surface 11 of the compressor main body, and the second connecting portion 32 is connected to the second top end surface 21 of the accumulator, so that the rigidity of the connecting bracket 30 in the tangential direction of the compressor main body 10 can be improved, the first-order and second-order modal frequencies of the accumulator 20 can be increased to 3000Hz or higher, and the low-frequency radiation noise of the compressor main body 10 can be improved. It should be noted that the first-order mode appears when the excitation frequency of the external force is equal to the natural frequency of the object, and the second-order mode appears when the excitation frequency of the external force is twice the natural frequency of the object.
Preferably, the connecting bracket 30 is a sheet metal part, and the sheet metal part is formed by a sheet metal through a comprehensive cold machining process, so that the rigidity of the connecting bracket 30 along the extending direction of the connecting bracket is far greater than the rigidity along the axial direction of the connecting bracket. It should be noted that stiffness refers to the ability of a material or structure to resist elastic deformation when subjected to a force.
Further, there is a height difference between the first connecting portion 31 and the second connecting portion 32 along the axial direction of the compressor main body 10, that is, the first connecting portion 31 and the second connecting portion 32 are not coplanar. In an exemplary embodiment, the distance between the first connecting portion 31 and the compressor suction port 13 along the axial direction of the compressor main body 10 is smaller than the distance between the second connecting portion 32 and the compressor suction port 13 along the axial direction of the compressor main body 10, that is, the axial distance from the first tip end surface 11 to the compressor suction port 13 is smaller than the axial distance from the second tip end surface 21 to the compressor suction port 13. In another exemplary embodiment, the distance of the first connection portion 31 with respect to the compressor suction port 13 in the axial direction of the compressor main body 10 is greater than the distance of the second connection portion 32 with respect to the compressor suction port 13 in the axial direction of the compressor main body 10.
Further, the thickness of the connection bracket 30 in the axial direction of the compressor main body 10 is not less than 2 mm. So configured, the rigidity of the connecting bracket 30 in the portion perpendicular to the axial direction of the compressor main body 10 can be made to meet practical assembly requirements.
Optionally, the axis of the compressor body 10 is parallel to the axis of the accumulator 20, and the first top end face 11 is parallel to the second top end face 21; the first connection portion 31 is parallel to the second connection portion 32. It should be noted that the axis of compressor body 10 and the axis of accumulator 20 may also have a certain small included angle (for example + -5 °), which is negligible and should be understood as the axis of compressor body 10 and the axis of accumulator 20 are substantially parallel; similarly, the first tip face 11 and the second tip face 21 may have a certain small included angle (e.g., + -5 °), which is negligible and is understood to mean that the first tip face 11 and the second tip face 21 are substantially parallel. Obviously, the spatial geometrical relationship of the first connecting portion 31 and the second connecting portion 32 is the same as that of the first tip face 11 and the second tip face 21.
Alternatively, referring to fig. 3 and 4, the connecting bracket 30 is a plate-shaped member, specifically, the first connecting portion 31, the second connecting portion 32 and the transition portion 33 are respectively a plate-shaped member; one end of the transition portion 33 is connected to the first connection portion 31 in a common-edge manner, the other end of the transition portion 33 is connected to the second connection portion 32 in a common-edge manner, and further, the transition portion 33 is connected to the first connection portion 31 and the second connection portion 32 in a circular arc transition manner. In this way, the transition portion 33 can be prevented from being perpendicularly connected to the first connecting portion 31 and the second connecting portion 32, respectively, the effective connection area of the transition portion 33 in the direction perpendicular to the axial direction of the compressor main body 10 can be increased, and the rigidity of the connecting bracket 30 in the direction perpendicular to the axial direction of the compressor main body 10 can be further increased. Of course, in some embodiments, the transition portion 33 may also be an arc-shaped plate, or a plate with a plurality of arc sections, or a twisted plate, which may serve to connect the first connection portion 31 and the second connection portion 32, and the invention is not limited thereto.
Alternatively, referring to fig. 1, the compressor main body 10 has a protruding portion 12 protruding from the first top end 11 along its axial direction, the first connecting portion 31 has an open end 310 opening in a direction away from the second connecting portion 32, and the open end 310 is connected with a part of the contour of the protruding portion 12; the reservoir 20 has an air inlet pipe 22 penetrating through the second top end surface 21 along the axial direction thereof, the air inlet pipe 22 is used for communicating with the inner cavity of the reservoir 20, the second connecting portion 32 has a through hole 320 penetrating through the second connecting portion 32 along the axial direction of the reservoir 20, and the air inlet pipe 22 is sleeved with the second connecting portion 32 through the through hole 320. Specifically, the first top end surface of the compressor main body 10 is actually a surface of an upper cylinder cover of the compressor, and those skilled in the art can arrange the protruding portion 12 with different shapes according to the actual surface of the upper cylinder cover, so that at least a part of the contour of the protruding portion 12 is matched with the opening end 310 of the first connecting portion 31.
Optionally, a gap exists between the compressor main body 10 and the liquid accumulator 20 along a direction perpendicular to the axial direction of the compressor main body, and the distance is not more than 5mm, so that the distance from the liquid accumulator 20 to the central axis of the compressor main body 10 is within a practical requirement range.
