[0038] Please refer to Figures 1 to 3The utility model discloses a compressor 100. Compressor 100 includes casing 101, crankcase 102, stator 103 and suspension structure 104. Casing 101 is equipped with containing chamber 1011 in. Crankcase 102 is located containing chamber 1011. Stator 103 is located containing chamber 1011 and is located the bottom of crankcase 102. Suspension structure 104 is located containing chamber 1011. Suspension structure 104 includes first elastic connecting piece 105 and second elastic connecting piece 106. First elastic connecting piece 105 connects the one side of stator 103 towards crankcase 102 and casing 101. Second elastic connecting piece 106 connects the one side of stator 103 away from crankcase 102 and casing 101. First elastic connecting piece 105 is connected with stator 103 and forms first connecting place 1051, and second elastic connecting piece 106 is connected with stator 103 and forms second connecting place 1061. First connecting place 1051 and second connecting place 1061 are located both ends of stator 103 along the radial direction.

[0039] In the above compressor 100, the first elastic connecting piece 105 connects the one side of the stator 103 towards the crankcase 102 and the casing 101, the second elastic connecting piece 106 connects the one side of the stator 103 away from the crankcase 102 and the casing 101, and the first connecting place 1051 and the second connecting place 1061 are located at both ends of the stator 103 along the radial direction. Therefore, the force received by the first elastic connecting piece 105 and the force received by the second elastic connecting piece 106 are in opposite directions, which can reduce the vibration of the compressor 100 when working at low speed and improve the decoupling rate of the compressor 100.

[0040] Specifically, the compressor 100 is a mechanical device that compresses low-pressure gas (such as air, refrigerant, or other gas) into high-pressure gas. The compressor can reduce the volume of the gas through mechanical movement, thereby increasing the pressure of the gas. The compressor 100 can include but is not limited to a piston compressor, a screw compressor, a centrifugal compressor, a sliding vane compressor, etc.

[0041] The compressor 100 can include a compressor pump body and a casing 101. The compressor pump body can include a crankcase 102, a suspension structure 104, a cylinder, a piston assembly, a motor assembly, etc.

[0042] The casing 101 is an external protective structure with a containing chamber 1011 inside. The crankcase 102, the suspension structure 104, and the cylinder can be contained in the containing chamber 1011. The casing 101 can wrap and support the crankcase 102, the suspension structure 104, and the cylinder to protect them from external environmental and external physical or chemical damage.

[0043] The crankshaft is a component that can convert rotary motion into linear reciprocating motion. The cylinder can be responsible for containing the piston assembly and providing compression space for the gas.

[0044] The motor assembly can convert electrical energy into mechanical energy to rotate the crankshaft, thereby driving the reciprocating movement of the piston assembly in the cylinder to compress the gas in the cylinder. The motor assembly includes a stator 103.

[0045] The stator 103 is located at the bottom of the crankcase 102. The crankcase 102 can accommodate the crankshaft to support and protect the crankshaft and related moving parts, so that the crankshaft can rotate smoothly.

[0046] In related technologies, in some conventional reciprocating compressors, the compressor is supported by four springs located below the stator. Due to the flexibility and freedom of the springs themselves, the compressor pump body can move freely in six directions (along the X-axis translation direction, along the Y-axis translation direction, along the Z-axis translation direction, around the X-axis rotation direction, around the Y-axis rotation direction, and around the Z-axis rotation direction). When the compressor is running, the torque fluctuation generated by the motor assembly can cause the compressor pump body to rotate around the X-axis and translate in the Z direction, and the rotation of the compressor pump body around the X-axis can be coupled with other rigid body motion modes, ultimately leading to the intensification of the vibration of the compressor pump body and the "shaking" phenomenon. Since the inertia is small under the working condition of low speed operation of the compressor, it cannot stably and smoothly output torque, and at this time, the torque output by the motor assembly is more easily affected by factors such as load change, air flow or gas pressure, and the torque fluctuation is often larger. Therefore, the "shaking" phenomenon is particularly obvious when the compressor is running at low speed.

[0047] In the embodiment of the utility model, in order to reduce the vibration of the compressor 100 when working at low speed, and improve the decoupling rate of the compressor 100, the compressor 100 comprises a suspension structure 104, which is arranged in the accommodating cavity 1011 of the shell 101.

[0048] The suspension structure 104 comprises a first elastic connecting piece 105 and a second elastic connecting piece 106. The first elastic connecting piece 105 and the second elastic connecting piece 106 are components with certain elasticity, which can absorb and alleviate mechanical vibration and impact.

[0049] The first elastic connecting piece 105 connects one side of the stator 103 facing the crankcase 102 and the shell 101. The second elastic connecting piece 106 connects one side of the stator 103 away from the crankcase 102 and the shell 101. The first elastic connecting piece 105 is connected with the stator 103 to form a first connecting part 1051, and the second elastic connecting piece 106 is connected with the stator 103 to form a second connecting part 1061. The first connecting part 1051 and the second connecting part 1061 are located at the two ends of the stator 103 in the radial direction. The first connecting part 1051 and the second connecting part 1061

[0050] It can be understood that the first elastic connecting member 105 and the second elastic connecting member 106 are connected to the side of the stator 103 facing the crankcase 102 and the side of the stator 103 facing away from the crankcase 102, respectively, and the first elastic connecting member 105 and the second elastic connecting member 106 can be subjected to forces in opposite directions when the compressor 100 generates vibrations. In an embodiment, the first elastic connecting member 105 is subjected to a tensile force, which is directed upward (toward the direction of the crankcase 102), and the second elastic connecting member 106 is subjected to a compressive force, which is directed downward (away from the direction of the crankcase 102).

[0051] It can be understood that the radial direction of the stator 103 is perpendicular to the axial direction of the stator 103. That is, the first connection 1051 and the second connection 1061 are located at the two ends of the stator 103 in the radial direction and on the two sides of the stator 103 in the axial direction.

[0052] It can be understood that, due to the elastic properties of the first elastic connecting member 105 and the second elastic connecting member 106, the first elastic connecting member 105 and the second elastic connecting member 106 can generate first support forces and second support forces in opposite directions when subjected to forces in opposite directions.

[0053] It can be understood that the first support forces and the second support forces in opposite directions can optimize the torque balance of the entire compressor 100, especially in low-speed operating conditions, and can to some extent reduce the degree of fluctuation of the torque, thereby reducing the vibration and motion coupling phenomenon caused by unbalanced torque, and thus reducing the vibration of the compressor 100 when operating in low-speed operating conditions, while improving the decoupling rate of the compressor 100.

[0054] Optionally, the size of the crankcase 102 in the axial direction of the stator 103 can be determined according to the structural space requirement and the size of the first elastic connecting member 105.

[0055] Optionally, the number of the first elastic connecting member 105 and the second elastic connecting member 106 can be one or more, and one first elastic connecting member 105 and one second elastic connecting member 106 correspond to each other.

[0056] In some embodiments, please refer to Figure 5 , the connecting line L of the action point of the first support force F1 generated by the first elastic connecting member 105 and the action point of the second support force F2 generated by the second elastic connecting member 106 passes through the center of mass of the compressor pump body.

[0057] In the above embodiment, the connecting line L of the action points of the first support force F1 generated by the first elastic connecting member 105 and the second support force F2 generated by the second elastic connecting member 106 passes through the center of mass of the compressor pump body, which can further reduce the vibration of the compressor 100 in the low-speed working condition and improve the decoupling rate of the compressor 100.

[0058] Specifically, due to the elastic properties of the first elastic connecting member 105 and the second elastic connecting member 106, when the first elastic connecting member 105 and the second elastic connecting member 106 are subjected to forces in opposite directions, the first elastic connecting member 105 and the second elastic connecting member 106 will generate first support forces and second support forces in opposite directions, and the connecting line of the action points of the first support forces and the second support forces can pass through the center of mass of the compressor pump body.

[0059] It should be noted that in the embodiment of the utility model, the first elastic connecting member 105 and the second elastic connecting member 106 can be uniformly and symmetrically stressed, so that the action points of the first support force and the second support force are located at the center of mass or the stress transmission point of the first elastic connecting member 105 and the second elastic connecting member 106, that is, the midpoint of the elastic connecting member.

[0060] It can be understood that the connecting line of the action points of the first support force and the second support force can pass through the center of mass of the compressor pump body, which can further optimize the moment balance of the entire compressor 100, especially in the low-speed working condition, the fluctuation degree of the torque can be further reduced, thereby further reducing the vibration and motion coupling phenomenon caused by the unbalanced torque, and further reducing the vibration of the compressor 100 in the low-speed working condition and improving the decoupling rate of the compressor 100.

[0061] In some embodiments, please refer to Figure 1 The first end of the first elastic connecting member 105 is fixedly connected with the stator 103, and the second end is connected with the shell 101 through the elastic support 107.

[0062] In the above embodiment, the first end of the first elastic connecting member 105 is fixedly connected with the stator 103, and the second end is connected with the shell 101 through the elastic support 107, so that the first elastic connecting member 105 is located on one side of the stator 103 in the axial direction, thereby realizing that the force received by the first elastic connecting member 105 and the force received by the second elastic connecting member 106 are in opposite directions, reducing the vibration of the compressor 100 in the low-speed working condition, and improving the decoupling rate of the compressor 100.

[0063] Specifically, the first end of the first elastic connecting member 105 is one end of the first elastic connecting member 105 connected with the stator 103, and the second end of the first elastic connecting member 105 is one end of the first elastic connecting member 105 away from the stator 103.

[0064] The elastic support 107 can provide a supporting and fixing base for the first elastic connecting piece 105, so that the first elastic connecting piece 105 can be stably connected with the shell 101 and play an elastic role, thereby helping to reduce vibration and improve the decoupling performance of the compressor 100 as a whole.

[0065] In some embodiments, please refer to Figure 1 The elastic support 107 is provided with a first mounting hole 108, and the second end of the first elastic connecting piece 105 is provided with a mounting ring 109. The second end of the first elastic connecting piece 105 is connected with the elastic support 107 by penetrating the mounting ring 109 and the first mounting hole 108 with a first fastener (not shown).

[0066] In the above embodiment, the second end of the first elastic connecting piece 105 is connected with the elastic support 107 by penetrating the mounting ring 109 and the first mounting hole 108 with the first fastener, so that the first elastic connecting piece 105 is located on one side of the stator 103 in the axial direction, thereby realizing that the force acting on the first elastic connecting piece 105 and the force acting on the second elastic connecting piece 106 are in opposite directions, reducing the vibration of the compressor 100 when working in a low-speed operating condition, and improving the decoupling rate of the compressor 100.

[0067] Specifically, the first connecting part 122 of the elastic support 107 is connected with the shell 101 to form a third connecting part 1071, and the bending part 121 is connected with the second end of the first elastic connecting piece 105.

[0068] The elastic support 107 and the shell 101 can be fixedly connected by welding, bolting, riveting, bonding or buckle type connection, and the specific embodiments of the present application are not limited. The third connecting part 1071 can be located at any position on the inner surface of the shell 101, which can be determined by the mechanical performance requirement, the structure space limitation, the installation and maintenance convenience and other factors, and the specific embodiments of the present application are not limited. In Figure 2 In the embodiment shown in

[0069] The elastic support 107 and the first elastic connecting piece 105 can be connected by the cooperation of the mounting ring 109, the first mounting hole 108 and the first fastener. It can be understood that the first fastener can include but is not limited to a screw, a bolt, a rivet, a pin or a buckle, etc.

[0070] In one embodiment, the first fastener is a screw. The screw has an external thread, and correspondingly, the compressor 100 includes a connecting piece with an internal thread. After the screw penetrates the mounting ring 109 and the first mounting hole 108, the screw and the connecting piece are fastened by threads to realize the connection of the second end of the first elastic connecting piece 105 with the elastic support 107.

[0071] In some embodiments, please refer to Figure 3 The elastic support 107 includes a bending portion 121 and a first connecting portion 122, the first connecting portion 122 is connected with the housing 101 to form a third connecting portion 1071, one end of the bending portion 121 is connected with the first connecting portion 122, and the bending portion 121 is bent away from the third connecting portion 1071 along the first connecting portion 122.

[0072] In the above embodiment, the bending portion 121 can effectively disperse the external force or internal pressure applied on the elastic support 107, and to a certain extent, avoid stress concentration to cause damage to the elastic support 107, thereby increasing the service life and durability of the elastic support 107, and at the same time, keeping the first elastic connecting piece 105 connected with the housing 101 by the elastic support 107 to a certain degree of stability, which is conducive to reducing the vibration of the compressor 100 when working in a low speed condition, and at the same time, improving the decoupling rate of the compressor 100.

[0073] Specifically, one end of the bending portion 121 is connected with the first connecting portion 122, and the other end is bent away from the third connecting portion 1071, thereby forming a mechanical support structure to improve the rigidity and mechanical properties of the elastic support 107.

[0074] In the process that the first elastic connecting piece 105 is connected with the housing 101 by the elastic support 107, the bending portion 121 can disperse the effect of external force or internal pressure, avoid stress concentration, and enhance the durability of the elastic support 107, so that the first elastic connecting piece 105 can maintain a certain degree of stability when subjected to external force or pressure.

[0075] In some embodiments, please refer to Figure 1 The suspension structure 104 includes a connecting sheet 110 and a second fastener 111, the connecting sheet 110 is arranged on the side of the stator 103 away from the crankcase 102, the second fastener 111 penetrates the first end of the first elastic connecting piece 105 and the stator 103, and is connected with the connecting sheet 110 to connect the first elastic connecting piece 105 with the stator 103.

[0076] In the above embodiment, the connecting sheet 110 is arranged on the side of the stator 103 away from the crankcase 102, the second fastener 111 penetrates the first end of the first elastic connecting piece 105 and the stator 103, and is connected with the connecting sheet 110 to connect the first elastic connecting piece 105 with the stator 103, so that the first elastic connecting piece 105 is located on one side of the stator 103 in the axial direction, thereby realizing that the force received by the first elastic connecting piece 105 and the force received by the second elastic connecting piece 106 are in opposite directions, reducing the vibration of the compressor 100 when working in a low speed condition, and at the same time, improving the decoupling rate of the compressor 100.

[0077] Specifically, the connecting piece 110 can cooperate with the second fastener 111 to fix the first end of the first elastic connecting piece 105 to the side of the stator 103 facing away from the crankcase 102.

[0078] It can be understood that, after the second fastener 111 is inserted through the first end of the first elastic connecting piece 105 and the stator 103 and connected to the connecting piece 110, the connecting piece 110 abuts against the side of the stator 103 facing away from the crankcase 102, so that the relative position between the first elastic connecting piece 105 and the stator 103 can be defined in the axial direction of the stator 103.

[0079] Optionally, the second fastener 111 can include, but is not limited to, a screw, a bolt, a rivet, a pin, or a buckle, etc. Correspondingly, the connecting piece 110 is a component that can cooperate with the second fastener 111.

[0080] In an embodiment, the second fastener 111 is a screw. The screw has external threads, and correspondingly, the stator 103 has a first through hole 119, and the connecting piece 110 has a second mounting hole 117 provided with internal threads. After the screw is inserted through the first end of the first elastic connecting piece 105 and the first through hole 119, the screw is fastened with the second mounting hole 117 by threads, so as to connect the first end of the first elastic connecting piece 105 to the side of the stator 103 facing the crankcase 102.

[0081] In some embodiments, please refer to Figure 1 The suspension structure 104 includes a plurality of first elastic connecting pieces 105 and a plurality of second fasteners 111, and each second fastener 111 is inserted through the first end of a corresponding first elastic connecting piece 105 and connected to the same connecting piece 110.

[0082] In the above embodiment, each second fastener 111 is inserted through the first end of a corresponding first elastic connecting piece 105 and connected to the same connecting piece 110, which can reduce the number of components, thereby reducing the manufacturing cost to some extent, simplifying the structure of the compressor 100, and improving the compactness of the structure of the compressor 100.

[0083] Specifically, in an embodiment, the plurality of second fasteners 111 are screws. The screws have external threads, and correspondingly, the stator 103 has a plurality of first through holes 119, and the connecting piece 110 has a plurality of second mounting holes 117, each of which is provided with internal threads.
