[0037] In the related art, in order to reduce the vibration transmission of the stator and the crankcase to the housing, a spring body is generally arranged between the housing and the stator. However, during the start-stop and operation of the compressor, the spring body is often moved or the spring wires of the spring body collide to cause noise due to the large vibration of the stator and the crankcase, which reduces the damping effect of the stator and the crankcase, causes the housing to resonate, and increases the noise generated during the operation of the compressor.

[0038] Reference Figures 1 to 3 , Figure 1 Fig. 1 shows a schematic view of the internal structure of a compressor according to an embodiment of the present application, Figure 2 Fig. 2 shows a schematic view of the internal structure of a compressor according to another embodiment of the present application, Figure 1 Fig. 3 shows a partial enlarged view of part A in Fig. 2, and Figure 3The assembly diagram of the damping assembly is shown in the embodiment of the utility model. Figures 1 to 3 As shown in the figure, the utility model discloses a compressor, including casing 100, support 200, pump body, motor 400 and multiple damping assemblies 500, casing 100 is equipped with containing cavity 110, support 200, pump body, motor 400 and multiple damping assemblies 500 are all arranged in containing cavity 110, support 200 is connected with the bottom wall of casing 100, the pump body includes crankcase 310, cylinder body, piston, connecting rod and crankshaft 320, the crankshaft 320 is vertically installed in the crankcase 310, the cylinder body is arranged on the upside of the crankcase 310, and the cylinder body has cylinder cavity, one end of the connecting rod is connected with the piston, the other end of the connecting rod is connected with the eccentric part of the crankshaft 320, the piston can reciprocate in the cylinder cavity under the rotation movement of the crankshaft 320, the motor 400 includes stator 410 and rotor 420 that rotates in the stator 410, the stator 410 is connected with the downside of the crankcase 310, and the rotor 420 is fixedly connected with the crankshaft 320, the damping assembly 500 is connected between support 200 and stator 410, and multiple damping assemblies 500 are arranged at intervals around the circumference of the crankshaft 320, the damping assembly 500 includes coaxially arranged spring 510 and elastic sleeve 520, the elastic sleeve 520 is sleeved on the outer periphery of the spring 510, along the radial direction of the spring 510, the spring 510 and the elastic sleeve 520 completely overlap, by setting spring 510 and elastic sleeve 520, the stator 410 and the crankcase 310 can be double-damped, the vibration of the stator 410 and the crankcase 310 can be effectively buffered, thereby reducing the vibration transmission of the stator 410 and the crankcase 310 to the casing 100, resonance of the casing 100 can be avoided, and the noise generated when the compressor works can be reduced.

[0039] For example, when the compressor works, the stator 410 drives the rotor 420 to drive the crankshaft 320 to rotate, under the rotation movement of the crankshaft 320, the eccentric part of the crankshaft 320 drives the piston to reciprocate in the cylinder cavity through the connecting rod, so as to compress the refrigerant in the cylinder cavity, because the piston, the connecting rod and the crankshaft 320 are in high-speed motion state, the stator 410 and the crankcase 310 will produce certain vibration, through spring 510 and elastic sleeve 520 between stator 410 and support 200, when the stator 410 extrudes spring 510 and elastic sleeve 520, spring 510 and elastic sleeve 520 produce elastic deformation to absorb the vibration energy of the stator 410 and the crankcase 310, the stator 410 and the crankcase 310 can be double-damped, the vibration of the stator 410 and the crankcase 310 can be effectively buffered, thereby reducing the vibration transmission of the stator 410 and the crankcase 310 to the casing 100, resonance of the casing 100 can be avoided, and the noise generated when the compressor works can be reduced.

[0040] It should be noted that the spring 510 and the elastic sleeve 520 can also partially overlap along the radial direction of the spring 510, for example, the length of the spring 510 is greater than the length of the elastic sleeve 520 along the axial direction of the crankshaft 320, or the length of the elastic sleeve 520 is greater than the length of the spring 510, which is not limited here.

[0041] It should be noted that the plurality of damping assemblies 500 are uniformly arranged around the circumference of the crankshaft 320, so that the plurality of damping assemblies 500 are uniformly stressed, which is beneficial to improve the damping effect of the damping assembly 500, which will not be repeated here.

[0042] Referring to Figure 5 , Figure 5 is the assembly schematic view of another embodiment of the damping assembly of the utility model. For example Figure 5 As another embodiment, the positions of the spring 510 and the elastic sleeve 520 can also be interchanged, that is, the spring 510 is sleeved on the outer periphery of the elastic sleeve 520, which can also double-damp the stator 410 and the crankcase 310, which is not limited here.

[0043] It should be noted that the coaxial arrangement of the spring 510 and the elastic sleeve 520 means that the axis of the spring 510 is collinear with the axis of the elastic sleeve 520, which can also mean that the axis of the spring 510 is offset from the axis of the elastic sleeve 520 by a certain distance on the basis of the elastic sleeve 520 being sleeved on the spring 510 or the spring 510 being sleeved on the elastic sleeve 520, which is not limited here.

[0044] It should be noted that the elastic sleeve 520 can be configured with one or more, when the elastic sleeve 520 is configured with multiple, the plurality of elastic sleeves 520 are coaxially arranged, the spring 510 is arranged in the innermost elastic sleeve 520, or the spring 510 is sleeved on the outer periphery of the outermost elastic sleeve 520, or the elastic sleeve 520 is located between two adjacent elastic sleeves 520, which is not limited here.

[0045] It should be noted that when the elastic sleeve 520 is configured with multiple, the elastic sleeve 520 can be arranged on the outer periphery of the spring 510, and the elastic sleeve 520 is arranged at intervals along the circumference of the spring 510, which can multi-damp the stator 410 and the crankcase 310, and also can reduce the noise generated during the operation of the compressor, which will not be repeated here.

[0046] In the embodiment, the upper end of the spring 510 abuts against the lower end surface of the stator 410, the lower end of the spring 510 abuts against the support 200, the upper end of the elastic sleeve 520 abuts against the lower end surface of the stator 410, and the lower end of the elastic sleeve 520 abuts against the support 200. The vibration of the stator 410 and the crankcase 310 is directly transmitted to the support 200 through the spring 510 and the elastic sleeve 520. The vibration of the stator 410 and the crankcase 310 transmitted to the shell 100 can be attenuated, the assembly materials of the compressor can be reduced, and the assembly process of the compressor can be simplified, thereby improving the assembly materials of the compressor.

[0047] As another implementation, the upper end of the spring 510 can abut against the lower end surface of the stator 410 through a first gasket, and / or the lower end of the spring 510 can abut against the support 200 through a second gasket, and / or the upper end of the elastic sleeve 520 can abut against the lower end surface of the stator 410 through a third gasket, and / or the lower end of the elastic sleeve 520 can abut against the support 200 through a fourth gasket. The vibration of the stator 410 and the crankcase 310 transmitted to the shell 100 can also be attenuated, which is not limited herein.

[0048] It can be understood that the first gasket, the second gasket, the third gasket, and the fourth gasket can have rigidity or elasticity, which is not limited herein.

[0049] For example Figure 3 As shown, in order to avoid the collision between the adjacent wires of the spring 510 and the noise caused thereby, in the embodiment, on the basis that the elastic sleeve 520 is sleeved on the spring 510, the inner circumferential surface of the elastic sleeve 520 abuts against the outer circumferential surface of the spring 510. Even if the stator 410 and the crankcase 310 produce large vibration, the elastic sleeve 520 can limit the swing of the spring 510 along the radial direction of the spring 510, and the collision between the adjacent wires of the spring 510 can be avoided, thereby effectively reducing the noise generated during the operation of the compressor.

[0050] As another implementation, on the basis that the spring 510 is sleeved on the elastic sleeve 520, the outer circumferential surface of the elastic sleeve 520 abuts against the inner circumferential surface of the spring 510, which can also limit the swing of the spring 510 along the radial direction of the spring 510, which is not described herein again.

[0051] For example Figure 3 As shown, in the embodiment, the minimum wall thickness of the elastic sleeve 520 is T, which satisfies 1mm≤T≤3mm. On the one hand, the structural strength of the elastic sleeve 520 can be ensured to improve the service life of the elastic sleeve 520 and reduce the swing amplitude of the spring 510. On the other hand, the axial stiffness of the elastic sleeve 520 can be reduced to enable the elastic sleeve 520 to effectively buffer the stator 410 and the crankcase 310.

[0052] For example, if the wall thickness of the elastic sleeve 520 is less than 1 mm, the wall thickness of the elastic sleeve 520 is too small, the tangential deformation of the elastic sleeve 520 is too large when the elastic sleeve 520 is subjected to the tangential force, the service life of the elastic sleeve 520 is low, the swing amplitude of the spring 510 cannot be reduced, and the adjacent spring wires of the spring 510 are prone to collision; if the wall thickness of the elastic sleeve 520 is greater than 3 mm, the axial stiffness of the spring 510 is too large, which is not conducive to buffering the vibration of the stator 410 and the crankcase 310, and the noise generated during the operation of the compressor is large. Therefore, by designing the wall thickness of the elastic sleeve 520 to be 1 mm to 3 mm, the tangential stiffness of the elastic sleeve 520 can be ensured, the axial stiffness of the elastic sleeve 520 can be reduced, and the noise generated during the operation of the compressor can be reduced.

[0053] It should be noted that the wall thickness T of the elastic sleeve can be 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, and 3 mm, which is not limited here.

[0054] Referring to Figure 3 、 Figure 4 , Figure 4 is a top view of the damping assembly of the embodiment of the utility model. For example Figure 3 、 Figure 4 , in the embodiment, the spring 510 is a seat spring structure on the basis that the elastic sleeve 520 is sleeved on the spring 510, the spring 510 comprises a main body part 511 and an abutting part 512, the lower end of the main body part 511 abuts against the support piece 200, the upper end of the main body part 511 is connected with the abutting part 512, the abutting part 512 spirally extends to the inside of the main body part 511, which can increase the contact area of the spring 510 and the stator 410, so as to improve the connection reliability of the spring 510 and the stator 410.

[0055] For example, the upper side of the abutting part 512 abuts against the lower side of the stator 410, and the lower end of the main body part 511 abuts against the support piece 200. Since the abutting part 512 spirally extends to the inside of the main body part 511, the contact area of the spring 510 and the stator 410 can be increased, so as to improve the connection reliability of the spring 510 and the stator 410.

[0056] As another embodiment, the spring 510 can also be a compression spring structure, which can buffer the vibration generated during the operation of the stator 410 and the crankcase 310, which is not limited here.

[0057] For example Figure 2As shown, in the embodiment, the compressor further comprises a fastener 600, which is a bolt or a screw or the like, the fastener 600 comprises a rod portion 620 and a head portion 610, the head portion 610 is connected to one end of the rod portion 620, the other end of the rod portion 620 away from the head portion 610 is provided with a thread, a through hole 513 is formed at the middle position of the abutting portion 512, the stator 410 is provided with a through hole, the crankcase 310 is provided with a threaded hole, the rod portion 620 is arranged in the through hole 513 and the through hole, and the other end of the rod portion 620 away from the head portion 610 is threadedly connected with the threaded hole, the head portion 610 is located at the inner side of the main body portion 511 and abuts against the side of the abutting portion 512 away from the stator 410, so that the stator 410 and the spring 510 can be stably connected, the installation is more convenient, and the assembly efficiency of the compressor can be improved.

[0058] For example, when the spring 510 is assembled, the rod portion 620 is sequentially arranged in the through hole 513, the through hole and the threaded hole from bottom to top, because the abutting portion 512 is clamped between the head portion 610 and the stator 410, the abutting portion 512 is fixedly connected with the stator 410, the abutting portion 512, the stator 410 and the crankcase 310 are an integral structure, the abutting portion 512 moves with the vibration of the stator 410 and the crankcase 310, the main body portion 511 and the elastic sleeve 520 can respectively buffer the vibration of the stator 410 and the crankcase 310 transmitted to the abutting portion 512, so as to attenuate the vibration of the stator 410 and the crankcase 310 transmitted to the shell 100, and the noise generated by the compressor during operation can be reduced.

[0059] As another embodiment, the abutting portion 512 can also be connected with the stator 410 by welding, wherein the welding includes but is not limited to resistance welding, laser welding or ultrasonic welding and the like.

[0060] In the embodiment, on the basis that the elastic sleeve 520 is sleeved outside the spring 510, the support 200 comprises a support pin 210 and an elastic seat 220, the support pin 210 is connected with the bottom wall of the shell 100, the elastic seat 220 is sleeved outside the periphery of the support pin 210, the lower end of the elastic sleeve 520 and the lower end of the spring 510 respectively abut against the upper end surface of the elastic seat 220, because the elastic seat 220 has elasticity, the elastic seat 220 can absorb the vibration energy of the damping assembly 500 transmitted to the elastic seat 220, so as to attenuate the vibration of the stator 410 and the crankcase 310 transmitted to the shell 100, and the noise generated by the compressor during operation can be reduced.

[0061] For example, the support pin 210 is a columnar structure, the lower end of the support pin 210 is connected with the bottom wall of the shell 100, the elastic seat 220 is sleeved on the outer periphery of the support pin 210, and the elastic seat 220 abuts against the outer peripheral surface of the support pin 210, the relative position of the elastic seat 220 and the support pin 210 can be positioned, the elastic seat 220 can be made of rubber material or polyester material, so that the elastic seat 220 has elasticity and good corrosion resistance, on the one hand, the service life of the elastic seat 220 can be ensured, on the other hand, the vibration energy transmitted to the elastic seat 220 by the damping assembly 500 can be absorbed, so as to attenuate the vibration transmitted to the shell 100 by the movement, and the noise generated by the compressor during operation can be reduced.

[0062] As another embodiment, the support 200 can also only include the support pin 210, the lower end of the elastic sleeve 520 and the lower end of the spring 510 abut against the upper end surface of the support pin 210, which can also support the elastic sleeve 520 and the spring 510, which will not be described here.

[0063] It should be pointed out that the lower end of the support pin 210 is connected with the bottom wall of the shell 100 by welding, in order to improve the connection reliability between the support pin 210 and the shell 100, the end of the elastic seat 220 away from the spring 510 abuts against the bottom wall of the shell 100, so that the vibration of the movement is transmitted to the shell 100 through the damping assembly 500 and the elastic seat 220, which can reduce the vibration of the movement transmitted to the support pin 210, so as to reduce the cracking of the welding position between the support pin 210 and the shell 100.

[0064] It should be pointed out that the number of support pins 210 is equal to the number of damping assemblies 500, and the support pin 210 corresponds to the damping assembly 500 one by one, which will not be described here.

[0065] In this embodiment, the end of the elastic seat 220 away from the support pin 210 is provided with a positioning protrusion 221, the positioning protrusion 221 is a cylindrical structure, the positioning protrusion 221 is arranged upwardly, on the basis that the elastic sleeve 520 is sleeved on the spring 510, the outer diameter of the positioning protrusion 221 matches the inner diameter of the spring 510, the positioning protrusion 221 is arranged in the inside of the spring 510, and the positioning protrusion 221 abuts against the inner peripheral surface of the spring 510, so as to position the spring 510 in the circumferential direction, to position the relative position of the spring 510 and the elastic seat 220, and to reduce the offset of the spring 510 relative to the elastic seat 220.

[0066] As another implementation, on the basis that the spring 510 is sleeved outside the elastic sleeve 520, the outer diameter of the positioning protrusion 221 matches the inner diameter of the elastic sleeve 520, the positioning protrusion 221 is arranged in the inside of the elastic sleeve 520, and the positioning protrusion 221 abuts against the inner circumferential surface of the elastic sleeve 520, so that the elastic sleeve 520 can be circumferentially positioned, thereby reducing the offset of the elastic sleeve 520 relative to the elastic seat 220.

[0067] It can be understood that the elastic sleeve 520 is a rubber piece, which has higher structural strength, good elasticity, strong corrosion resistance, and long service life.

[0068] In the embodiment, the shell 100 includes an upper shell 100 and a lower shell 100, the upper shell 100 is buckled with the lower shell 100, so that the upper shell 100 and the lower shell 100 enclose the accommodation cavity 110, the support 200 is connected with the bottom wall of the lower shell 100, and the upper shell 100 and the lower shell 100 are fixed by welding to seal the accommodation cavity 110, so that the sealing effect of the shell 100 can be improved.

[0069] The refrigeration equipment of the second embodiment of the utility model includes the compressor of the above-mentioned embodiment.

[0070] When the refrigeration equipment works, the vibration generated by the stator 410 and the crankcase 310 of the compressor is transmitted to the support 200 through the spring 510 and the elastic sleeve 520, the vibration received by the support 200 is transmitted to the shell 100, because the spring 510 and the elastic sleeve 520 are both elastic, when the stator 410 extrudes the spring 510 and the elastic sleeve 520, the spring 510 and the elastic sleeve 520 are elastically deformed to absorb the vibration energy of the stator 410 and the crankcase 310, the stator 410 and the crankcase 310 can be doubly damped, the vibration of the stator 410 and the crankcase 310 can be effectively buffered, so that the vibration of the stator 410 and the crankcase 310 transmitted to the shell 100 can be reduced, the resonance of the shell 100 can be avoided, and the noise generated when the refrigeration equipment works can be reduced.

[0071] Because the refrigeration equipment adopts all the technical solutions of the compressor of the above-mentioned embodiment, at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiment are possessed, which will not be repeated here.

[0072] The above describes one embodiment of the utility model in combination with the drawings, but the utility model is not limited to the above-mentioned embodiment, and various changes can be made within the knowledge range possessed by ordinary skilled in the art without departing from the purpose of the utility model.
