[0001] The present invention relates to the technical field of compressors, and in particular to a vibration reduction component, a compressor and a refrigeration device. Background Art

[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0041] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, assembling, and matching should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0042] The refrigeration function of refrigerators, freezers, freezers and other equipment is mainly realized by compressors. During the repeated start and stop and high-load operation of the compressor, its vibration reduction system plays a role in buffering and absorbing vibration energy to ensure that the compressor can operate stably.

[0043] Among them, the vibration reduction system mainly achieves vibration reduction through the seat spring 450, refer to Figure 1 As shown, in the prior art, a first bushing 430 is installed on the lower side of the stator 421 of the compressor movement through a screw 423, and the upper end of the seat spring 450 is sleeved on the first bushing 430. A second bushing 440 is installed on the housing of the compressor through a positioning pin 411, and the second bushing 440 is located on the lower side of the first bushing 430. The lower end of the seat spring 450 is sleeved on the second bushing 440, thereby achieving vibration reduction. However, the vibration reduction system of this connection structure has the following disadvantages: during the operation of the compressor, the seat spring 450 will move axially relative to the bushing and generate friction noise, that is, the seat spring 450 will move along the axial direction of the bushing, which will cause the spring to come off, thereby causing the vibration reduction failure problem and affecting the normal operation of the compressor.

[0044] To solve the above problems, refer to Figures 2 to 5 As shown, a first aspect of an embodiment of the present invention provides a vibration reduction assembly, which is applied to a compressor, such as a variable frequency compressor.

[0045] The specific connection structure of the vibration reduction assembly is described in detail below in conjunction with the compressor.

[0046] Reference Figure 2 As shown, it can be understood that the compressor 400 includes a housing 410 and a movement 420, and the movement 420 is installed inside the housing 410. The movement 420 includes a stator 421 and a crankcase 422, the crankcase 422 is located on the upper side of the stator 421, and the lower side of the movement 420 is installed on the housing 410 through a vibration reduction assembly, wherein the vibration reduction assembly is connected to the stator 421 and the crankcase 422 to provide a buffering effect on the movement 420 and absorb vibration energy, ensuring that the compressor 400 can operate normally. It is easy to understand that a plurality of vibration reduction assemblies arranged at intervals are generally connected between the movement 420 and the housing 410.

[0047] Reference Figures 2 to 4As shown, it can be understood that the vibration reduction assembly includes a first mounting seat 100, and the first mounting seat 100 is generally a columnar structure. Specifically, the first mounting seat 100 includes a base 110 and a positioning column 120. The base 110 and the positioning column 120 are both cylindrical. The positioning column 120 is arranged on the upper side of the base 110 and extends upward, and the center line of the positioning column 120 coincides with the center line of the base 110. The base 110 and the positioning column 120 can be an integrally formed structure for easy processing. Generally speaking, the outer diameter of the base 110 is larger than the outer diameter of the positioning column 120, and along the center line direction of the base 110, the height of the base 110 is smaller than the height of the positioning column 120.

[0048] Reference Figure 3 and Figure 4 As shown, it can be understood that the first mounting seat 100 is provided with a plurality of first buckle parts 130, specifically, the first mounting seat 100 is provided with four first buckle parts 130, the first buckle parts 130 are connected to the peripheral wall of the positioning column 120, and the four first buckle parts 130 are arranged at equal intervals along the circumference of the positioning column 120. The first buckle part 130 is configured as a claw structure, and the claw structure has elasticity. Under the action of external force, the claw structure can deflect inward along the radial direction of the positioning column 120, and the claw structure automatically resets after the external force is removed. Of course, the first buckle part 130 can also be a structure with elasticity itself, that is, it can be compressed and deformed under the action of external force, such as a rubber part, etc. The first buckle part 130 can also be a wedge-shaped structure.

[0049] Of course, it is easy to understand that the number of the first buckle parts 130 can also be three, five or more, which will not be elaborated here.

[0050] Reference Figure 2 and Figure 3 As shown, it can be understood that the first mounting seat 100 is fixedly mounted on the inner side of the bottom wall of the housing 410 and is located on the lower side of the movement 420. Specifically, the first mounting seat 100 is provided with a positioning hole 160, which is a blind hole and opens downward, and the positioning hole 160 is extended along the center line of the base 110. Correspondingly, the inner wall of the housing 410 is provided with a positioning pin 411, and the positioning pin 411 is interference-fitted with the positioning hole 160. Therefore, the positioning pin 411 can be inserted into the positioning hole 160 to fix the first mounting seat 100 to the housing 410. At this time, the positioning column 120 is arranged upward, that is, the positioning column 120 faces the movement 420.

[0051] Reference Figure 3 and Figure 5As shown, it can be understood that the vibration reduction assembly also includes an elastic member 200, and the elastic member 200 is a coil spring. Specifically, the coil spring is formed by the spiral extension of the spring wire, and a through hole 210 is formed in the middle of the coil spring, and the through hole 210 runs through the axial direction of the coil spring. Generally speaking, the coil spring includes a densely wound portion 220 and a sparsely wound portion 230. Specifically, the two ends of the coil spring along the axial direction are the densely wound portions 220, and the space between the two ends is the sparsely wound portion 230. The densely wound portion 220 is the distance between two adjacent coils of the spring wire is small, and the sparsely wound portion 230 is the distance between two adjacent coils of the spring wire is large, that is, the pitch of the densely wound portion 220 is smaller than the pitch of the sparsely wound portion 230. The pitch of the densely wound part 220 is equal to the diameter of the spring wire, that is, the two adjacent coils of the densely wound part 220 fit each other, and the pitch of the sparsely wound part 230 is greater than the diameter of the spring wire, for example, the pitch of the sparsely wound part 230 is 1.5 times or twice the diameter of the spring wire, and the ends of the coil spring are round. Therefore, the densely wound parts 220 at both ends can facilitate the fixing of the ends of the coil spring, and the sparsely wound part 230 in the middle makes the coil spring have sufficient elasticity to achieve vibration reduction.

[0052] Reference Figure 2 and Figure 3 As shown, it can be understood that the lower end of the elastic member 200 is sleeved on the outer periphery of the positioning column 120 through the through hole 210, and the center line of the elastic member 200 coincides with the center of the positioning column 120. Since the height of the positioning column 120 is relatively large, that is, a larger portion of the first mounting seat 100 is accommodated in the through hole 210, the elastic member 200 can be prevented from tilting when the elastic member 200 is installed, and radial support can be provided for the elastic member 200, which can achieve accurate positioning on the one hand, and prevent the elastic member 200 from tilting and causing vibration reduction failure on the other hand.

[0053] Reference Figure 2 and Figure 3As shown, it can be understood that as the lower end of the elastic member 200 moves downward and is sleeved on the positioning column 120, the tightly wound portion 220 at the lower end of the elastic member 200 can drive the four first buckle portions 130 to deflect radially inward, so that the distance from the first buckle portion 130 to the center line of the positioning column 120 is reduced, so that the elastic member 200 can move further downward until the end of the elastic member 200 abuts against the base 110, and the end of the elastic member 200 is the tightly wound portion 220. At this time, at least one spring wire of the tightly wound part 220 at the lower end of the elastic member 200 is located at the lower side of the first buckle part 130, and the first buckle part 130 is automatically reset, and the distance from the first buckle part 130 to the center line of the positioning column 120 increases, so that the first buckle part 130 clamps the lower end of the elastic member 200 to the first mounting seat 100, that is, the lower end of the elastic member 200 is limited to the first buckle part 130, and the elastic member 200 cannot move in the reverse direction relative to the first mounting seat 100, thereby limiting the elastic member 200 from axially separating from the first mounting seat 100. Therefore, the axial movement of the elastic member 200 relative to the first mounting seat 100 and the housing 410 can be avoided, and the elastic member 200 will not tilt, which effectively reduces the noise caused by the movement of the elastic member 200 relative to the first mounting seat 100, while ensuring the reliability of the vibration reduction assembly.

[0054] Reference Figure 2 and Figure 3 As shown, it can be understood that, similarly, in order to facilitate the connection between the elastic member 200 and the movement 420, the vibration reduction assembly also includes a second mounting seat 300, and the structure of the second mounting seat 300 can refer to the structure of the first mounting seat 100, which will not be repeated here. The second mounting seat 300 is provided with a plurality of second buckle parts 310, specifically, the second mounting seat 300 is provided with four second buckle parts 310, and the four second buckle parts 310 are all arranged on the peripheral wall of the second mounting seat 300 and are arranged at equal intervals along the circumference of the second mounting seat 300. The structure of the second buckle part 310 can refer to the structure of the first buckle part 130, which will not be repeated here.

[0055] Reference Figure 2 and Figure 3As shown, it can be understood that the second mounting seat 300 is fixedly mounted on the movement 420, specifically, the second mounting seat 300 is fixedly connected with the stator 421 and the crankcase 422 of the movement 420, and the second mounting seat 300 is provided with a fixing hole 320, the fixing hole 320 passes through along the axis of the second mounting seat 300, the fixing hole 320 is a stepped hole, and the large end of the stepped hole is farther away from the stator 421 than the small end. Correspondingly, the stator 421 is provided with an opening, the center line of the opening coincides with the center line of the fixing hole 320, and the crankcase 422 is provided with a threaded hole, the center line of the threaded hole coincides with the center line of the fixing hole 320. The movement 420 is connected with a screw 423, the screw 423 passes through the fixing hole 320, the opening and is connected with the threaded hole in sequence, so that the second mounting seat 300 can be fixed to the stator 421 by the screw 423. In order to make the second mounting seat 300 installed more firmly, a gasket 424 is further provided between the second mounting seat 300 and the stator 421 .

[0056] Reference Figure 2 and Figure 3 As shown, it can be understood that the upper end of the elastic member 200 is sleeved on the outer periphery of the second mounting seat 300 through the through hole 210. As the upper end of the elastic member 200 moves upward, the tightly wound portion 220 at the upper end of the elastic member 200 can drive the four second buckle portions 310 to swing radially inward, so that the elastic member 200 moves further upward until at least one spring wire of the tightly wound portion 220 at the upper end of the elastic member 200 is located on the upper side of the second buckle portion 310, and the second buckle portion 310 automatically resets. Thus, the second buckle portion 310 clamps the upper end of the elastic member 200 to the second mounting seat 300, that is, the upper end of the elastic member 200 is limited to the second mounting seat 300, and the elastic member 200 cannot move in the reverse direction relative to the second mounting seat 300, thereby preventing the elastic member 200 from axially disengaging from the second mounting seat 300 and preventing the elastic member 200 from axially moving relative to the second mounting seat 300 and the movement 420. The elastic member 200 is installed between the housing 410 and the movement 420 , and the elastic member 200 can be effectively prevented from loosening.

[0057] The two ends of the elastic member 200 are respectively limited to the first buckle portion 130 of the first mounting seat 100 and the second buckle portion 310 of the second mounting seat 300. There are fewer parts and components, which is easy to install. At the same time, on the one hand, the elastic member 200 can be positioned, and there will be no tilt when the elastic member 200 is installed, so that the center line of the elastic member 200 coincides with the center line of the positioning column 120. The positioning is accurate, which can avoid the elastic member 200 from tilting and causing vibration reduction failure. On the other hand, during the operation of the compressor 400, the elastic member 200 can be prevented from moving relative to the first mounting seat 100 and the second mounting seat 300, effectively reducing the risk of the elastic member 200 loosening, thereby reducing the noise generated by the movement of the elastic member 200 relative to the first mounting seat 100 and the second mounting seat 300, that is, it is greatly improved in reducing the low-frequency noise of the compressor 400, and at the same time, it is beneficial to improve the stability of the compressor 400 during operation.

[0058] In other embodiments, it is understood that the lower end of the elastic member 200 is connected to the housing 410 through the first mounting seat 100, and the upper end of the elastic member 200 can be directly fixed to the stator 421 by screws 423 or other fixing methods; or the upper end of the elastic member 200 is connected to the stator 421 through the second mounting seat 300, and the lower end of the elastic member 200 is directly fixed to the housing 410 by screws 423 or other fixing methods. The risk of the elastic member 200 being loosened can also be reduced.

[0059] The following is further explained by taking the specific structure of the first mounting seat as an example, and the specific structure of the second mounting seat can refer to the specific structure of the first mounting seat.

[0060] Reference Figure 3 and Figure 4As shown, it can be understood that the first buckle portion 130 is in the shape of an elongated strip, and the first buckle portion 130 includes a fixed end 131 and a free end 132, wherein the fixed end 131 is connected to the peripheral wall of the positioning column 120, and the free end 132 extends downward, that is, the free end 132 extends toward the base 110, and a clearance portion 140 is provided between the free end 132 and the peripheral wall of the positioning column 120, and the clearance portion 140 is the gap between the first buckle portion 130 and the peripheral wall of the positioning column 120, that is, the free end 132 is arranged at intervals from the positioning column 120. Therefore, the free end 132 can deflect along the radial direction of the positioning column 120. Generally speaking, the first buckle portion 130 is a plastic part, and the free end 132 is also automatically reset. When the elastic member 200 is sleeved on the positioning column 120, the elastic member 200 can drive the four first buckle parts 130 to shrink toward the center line of the positioning column 120. After the end of the elastic member 200 passes over the free end 132, the free end 132 automatically resets, and the free end 132 clamps the end of the elastic member 200, thereby limiting the end of the elastic member 200 to the first buckle part to prevent the elastic member 200 from loosening. Here, the end of the elastic member 200 passes over the free end 132, which means that the end of the elastic member 200 moves downward to the lower side of the free end 132.

[0061] Of course, it is understandable that the fixed end 131 of the first buckle portion 130 is connected to the peripheral wall of the positioning column 120 , and the free end 132 can extend upward, so that the free end 132 can also swing along the radial direction of the positioning column 120 .

[0062] Reference Figure 3As shown, it can be understood that the diameter of the through hole 210 is defined as D, and the maximum distance from the first buckle portion 130 to the center line of the positioning column 120 along the direction perpendicular to the center line of the positioning column 120, that is, along the radial direction of the positioning column 120, is R. Generally speaking, R is the maximum distance from the outer side of the free end 132 to the center line of the positioning column 120, and the outer side here is the side of the free end 132 away from the center line of the positioning column 120. Satisfies: 0.05mm≤(2R-D)≤0.15mm. In other words, the diameter of the circle with a radius of R, with the center line of the positioning column 120 as the center, is at least 0.05mm larger than the diameter of the through hole 210, that is, the space occupied by the four first buckle portions 130 in the radial direction of the positioning column 120 is larger than the through hole 210. When the center line of the elastic member 200 coincides with the center line of the positioning column 120, the end of the elastic member 200 passes over the free end 132 and after the free end 132 is reset, the free end 132 can limit the elastic member 200 from disengaging from the first buckle portion 130 in the reverse direction, thereby limiting the elastic member 200 in the first buckle portion 130 and preventing the elastic member 200 from loosening. By making (2R-D) ≤ 0.15 mm, it is possible to prevent the four first buckle portions 130 from occupying too much space in the radial direction of the positioning column 120, thereby increasing the difficulty of inserting the elastic member 200 into the positioning column 120 and making the end of the elastic member 200 pass over the free end 132, thereby facilitating assembly.

[0063] Reference Figure 3 and Figure 4 As shown, it can be understood that, in order to further reduce the difficulty of installing the elastic member 200, the first opening is provided with a first guide portion 133. Specifically, the first guide portion 133 is provided at the free end 132 and is located on the side of the free end 132 away from the escape portion 140. The first guide portion 133 is an arc surface or an inclined surface. Along the downward direction of the center line of the positioning column 120, that is, along the direction of the positioning column 120 toward the base 110, the distance from the first guide portion 133 to the center line of the positioning column 120 increases, so that the free end 132 is a wedge-shaped structure, and the lower end is large and the upper end is small. Therefore, when the elastic member 200 is sleeved on the positioning column 120 and moves downward, the lower end of the elastic member 200 contacts the first guide portion 133 and moves downward along the first guide portion 133. Under the guiding action of the first guide portion 133, the lower end of the elastic member 200 can smoothly and easily drive the free end 132 to swing toward the center line of the positioning column 120, so that the lower end of the elastic member 200 can pass over the free end 132 and limit the elastic member 200 to the first buckle portion 130, which is convenient for installation.

[0064] Reference Figure 3 and Figure 4As shown, it can be understood that, in order to further reduce the difficulty of installing the elastic member 200, the positioning column 120 is provided with a second guide portion 121. Specifically, the second guide portion 121 is located at the outer peripheral wall of the upper end of the positioning column 120, and the second guide portion 121 can be an inclined surface or an arc surface. Along the downward direction of the center line of the positioning column 120, that is, along the direction of the positioning column 120 toward the base 110, the distance from the second guide portion 121 to the center line of the positioning column 120 increases, so that the upper end of the positioning column 120 is truncated cone-shaped or conical, and the upper end is small and the lower end is large. At this time, the outer diameter of the upper end of the positioning column 120 is smaller than the inner diameter of the through hole 210. Therefore, when installing the elastic member 200, since the outer diameter of the top of the positioning column 120 is smaller than the inner diameter of the through hole 210, the positioning column 120 can be inserted into the through hole 210 even when the center line of the elastic member 200 does not completely coincide with the center line of the positioning column 120, thereby reducing the difficulty of sleeve the elastic member 200 on the positioning column 120, and under the guidance of the second guide portion 121, as the elastic member 200 moves downward, the center line of the elastic member 200 can be offset toward the center line of the positioning column 120 until they coincide, so as to position the elastic member 200 and prevent the elastic member 200 from tilting, thereby facilitating installation.

[0065] Reference Figure 3 and Figure 4 As shown, it can be understood that in order to make the elastic member 200 more firmly connected, the end face of the base 110 facing the positioning column 120 is defined as the first end face 111, that is, the upper end face of the base 110 is the first end face 111, and the lower end face of the free end 132 is the second end face 134. Generally speaking, the first end face 111 and the second end face 134 are parallel and arranged at intervals along the center line direction of the positioning column 120, and a limiting space 150 is defined between the first end face 111 and the second end face 134. When the lower end of the elastic member 200 passes over the free end 132, the end of the elastic member 200 is accommodated in the limiting space 150. For example, a circle of spring wire of the tightly wound portion 220 at the lower end of the elastic member 200 is accommodated in the limiting space 150. Of course, the number of spring wires accommodated in the limiting space 150 can also be two circles, three circles or more circles, thereby limiting the upward movement of the elastic member 200 and limiting the further downward movement of the elastic member 200, thereby preventing the elastic member 200 from loosening or moving, thereby ensuring the stable operation of the compressor 400.

[0066] It is understandable that the limiting space 150 can accommodate multiple coils of spring wire. Specifically, the number of spring wires required to be accommodated in the limiting space 150 is related to the weight of the movement 420. The greater the weight of the movement 420, the more spring wires are required to be accommodated, and vice versa.

[0067] Reference Figure 3As shown, it can be understood that the number of spring wires required to be accommodated in the limiting space 150 is defined as N, the diameter of the spring wire is d, and the maximum height of the limiting space 150 along the center line direction of the positioning column 120 is H, that is, the distance between the first end face 111 and the second end face 134 is H, which satisfies: 0.05mm≤(HN*d)≤0.1mm, that is, the maximum height of the limiting space 150 is 0.05-0.1mm greater than the sum of the diameters of the spring wires accommodated in the limiting space 150. When (HN*d)≥0.05mm, it can be ensured that the limiting space 150 can accommodate the set number of turns of spring wire; when (HN*d)≤0.1mm, it can be avoided that the maximum height of the limiting space 150 is too large to cause the elastic member 200 to loosen, and prevent the elastic member 200 from moving, that is, the end of the elastic member 200 is made to fit more closely with the limiting space 150.
