[0002] As people's demands for comfort increase, the quietness of air conditioner operation has become an important factor for users when choosing an air conditioner. The vibration of the compressor in the outdoor unit is a major source of noise, making vibration an important indicator of compressor quality. Scroll compressors, due to their high efficiency, small size, light weight, and low noise, are widely used in various air conditioners and refrigeration units. Scroll compressors mainly rely on a moving scroll plate working in conjunction with a fixed plate to block gas, and the planar rotation of the moving scroll plate achieves gas compression. Therefore, the moving scroll plate assembly, as the main moving component, is naturally the source of compressor vibration and noise. Research has found that the impact of the moving plate steel ring, used to prevent the moving scroll plate from rotating during its planar motion, is one of the main causes of vibration and noise in scroll compressors.

[0034] Please see Figures 1 to 9 This embodiment provides a vibration damping structure for a moving scroll plate, including a moving scroll plate 1, a support assembly 2, and a vibration damping assembly 3. The moving scroll plate 1 is disposed on the support assembly 3 and is movable relative to the support assembly 3. The moving scroll plate 1 is provided with a vibration damping assembly groove 11, and the vibration damping assembly 3 is disposed in the vibration damping assembly groove 11. The support assembly 2 is provided with a cylindrical pin 21 corresponding to the vibration damping assembly groove 11. The upper end of the cylindrical pin 21 extends into the vibration damping assembly groove 11, and the moving scroll plate 1 is movable relative to the cylindrical pin 21. The vibration damping assembly 3 includes a metal ring 31, a first vibration damping part 32, and a second vibration damping part 33. The first vibration damping part 32 is disposed on the inner side of the metal ring 31, and the second vibration damping part 33 is disposed on the outer side of the metal ring 31.

[0035] In this embodiment, to suppress the rotation of the moving scroll plate 1 during operation, the moving scroll plate 1 is provided with a vibration damping component groove 11, and the support assembly 2 is provided with a cylindrical pin 21 corresponding to the vibration damping component groove 11. The cylindrical pin 21 extends into the vibration damping component groove 11 of the moving scroll plate 1, thereby limiting the rotation of the moving scroll plate 1. Since the moving scroll plate 1 will collide with the cylindrical pin 21 during operation, resulting in vibration and noise, a vibration damping component 3 is provided in the vibration damping component groove 11, so that a clearance fit is formed between the vibration damping component 3 and the vibration damping component groove 11. The vibration damping component 3 isolates the groove wall of the vibration damping component groove 11 from the cylindrical pin 21, thereby reducing the impact force between the groove wall of the vibration damping component groove 11 of the moving scroll plate 1 and the cylindrical pin 21, thus reducing vibration and noise.

[0036] Specifically, the vibration damping component 3 includes a metal ring 31 and a vibration damping part. The vibration damping part includes a first vibration damping part 32 and a second vibration damping part 33. The metal ring 31 is used to support the first vibration damping part 32 and the second vibration damping part 33, thereby improving the durability of the vibration damping component 3. The first vibration damping part 32 is disposed on the inner side of the metal ring 31 and is used to reduce the impact force of the cylindrical pin 21 on the metal ring 31. The second vibration damping part 33 is disposed on the outer side of the metal ring 31 and is used to reduce the impact force of the metal ring 31 on the groove wall of the vibration damping component groove 11 of the moving scroll.

[0037] The metal ring 31 is preferably made of wear-resistant metal materials, such as bearing steel, which can effectively reduce wear and achieve a longer service life.

[0038] The first damping part 32 and the second damping part 33 are preferably made of wear-resistant and high-temperature-resistant rubber materials with a Shore hardness of 40-60. The rubber materials are common rubbers such as butyl rubber and silicone rubber, and different formulations of rubber materials can be selected according to the refrigerant, refrigeration oil and operating temperature environment used in the compressor.

[0039] In one possible implementation, the first damping part 32 and the second damping part 33 are connected by a connecting part, the metal ring 31 is provided with a metal ring opening 311 corresponding to the connecting part, and the groove wall of the damping component groove of the moving scroll disk is provided with a slot corresponding to the second damping part 33.

[0040] In this embodiment, the structure of the vibration damping component groove of the moving scroll plate is improved to ensure that the vibration damping component 3 will not undergo axial displacement relative to the moving scroll plate 1. Specifically, the groove wall of the vibration damping component groove 11 of the moving scroll plate 1 is provided with an annular groove 12. The height of the groove 12 is adapted to the height of the second damping part 33. When the vibration damping component 3 is installed in the vibration damping component groove 11 of the moving scroll plate 1, the second damping part 33 of the vibration damping component 3 can be inserted into the groove 12 of the groove wall of the vibration damping component groove 11, thereby limiting the axial displacement of the vibration damping component 3 and preventing the metal ring 31 from colliding with the support assembly 2 and the moving scroll plate 1 in the axial direction, effectively reducing noise.

[0041] In one possible implementation, the diameter of the damping component groove 11 is d1, the diameter of the slot 12 is d2, the outer diameter of the metal ring 31 is d3, and the outer diameter of the second damping part 33 is d4, wherein d2-d4 < d1-d3.

[0042] In this embodiment, the dimensions of the vibration damping component groove 11, the slot 12, the metal ring 31, and the second vibration damping part 33 have been optimized to ensure the vibration damping and noise reduction effect. Specifically, the diameter of the vibration damping component groove 11 is d1, the diameter of the slot 12 is d2, the outer diameter of the metal ring 31 is d3, and the outer diameter of the second vibration damping part 33 is d4. Wherein, d1, d2, d3, and d4 satisfy the condition: d2 - d4 < d1 - d3. That is, the distance from the outer edge of the second vibration damping part 33 to the groove wall of the slot 12 is less than the distance from the outer edge of the metal ring 31 to the groove wall of the vibration damping component groove 11. The second vibration damping part 33 can contact the groove wall of the slot 12 earlier than the metal ring 31, thereby reducing the impact force and achieving the effect of reducing vibration and noise.

[0043] In one possible implementation, the axial length of the second damping part is less than the axial length of the first damping part.

[0044] In this embodiment, the structure of the second damping part 33 has been improved to facilitate the assembly of the damping component 3 and to enhance the damping effect of the second damping part 33. Specifically, the axial length of the second damping part 33 is made smaller than the axial length of the first damping part 32, so that the axial length of the second damping part 33 matches the width of the metal ring opening 311. The radial width of the second damping part 33 is increased so that the second damping part 33 surrounds the first damping part 32 in a ring shape. During assembly, an external force is applied to the first damping part 32 to deform the entire rubber ring and insert it into the inside of the metal ring 31. By extending the second damping part 33 from the metal ring opening 311 to the outside of the metal ring 31, the first damping part 32 and the second damping part 33 return to their original shape under the action of elasticity, thus completing the assembly, which is very convenient. By increasing the radial width of the second damping part 33, the buffer distance between the damping component 3 and the groove wall of the damping component groove 11 of the moving scroll disk 1 is increased, which can better reduce the impact force of the damping component 3 on the groove wall of the damping component groove 11 of the moving scroll disk 1.

[0045] In one possible implementation, the first damping part, the second damping part, and the connecting part are an integral structure.

[0046] In this embodiment, the structures of the first damping part 32 and the second damping part 33 have been improved to ensure the damping effect while increasing the connection reliability between the first damping part 32, the second damping part 33 and the metal ring 31. Specifically, the first damping part 32 and the second damping part 33 are rubber rings with an integral structure. The first damping part 32 and the second damping part 33 are connected by a connecting part. The metal ring 31 has a metal ring opening 311 corresponding to the connecting part. During assembly, an external force is applied to the first damping part 32, the second damping part 33 and the connecting part to deform them. The rubber ring is inserted into the inside of the metal ring 31. By extending the second damping part 33 from the metal ring opening 311 to the outside of the metal ring 31, the first damping part 32 and the second damping part 33 return to their original shape under the action of elasticity. At this time, the first damping part 32 is inside the metal ring 31, the second damping part 33 is outside the metal ring 32, and the connecting part is located at the metal ring opening 311. The assembly is very convenient, and the first damping part 32 and the second damping part 33 are not easy to fall off the metal ring 31, which increases the reliability of the damping component 3.

[0047] In one possible implementation, there are at least two second damping portions, with an opening formed between two adjacent second damping portions, the included angle of the opening being α. Where N is the number of vibration damping component slots of the moving scroll disk.

[0048] In this embodiment, the structure of the second damping part 33 has been improved to ensure the damping effect of the damping assembly 3. Specifically, this embodiment uses two second damping parts 33 as an example. The two second damping parts 33 are evenly arranged on the outside of the first damping part 32 along the circumferential direction. The side of the metal ring 31 is provided with two metal ring openings 311 corresponding to the two second damping parts 33. The side of the metal ring 31 is H-shaped. During assembly, the rubber ring composed of the first damping part 32, the second damping part 33 and the connecting part is pressed and deformed, and inserted into the middle of the metal ring 31. The two second damping parts 33 are each extended from one metal ring opening 311 to the outside of the metal ring 31, thus completing the assembly of the damping assembly 3, which is very convenient.

[0049] At this time, in order to match the two metal ring openings 311 of the metal ring 31, a damping opening 331 will be formed between the two second damping parts 33. Since the movement relationship between the damping component groove 11 and the cylindrical pin 21 is disengagement-contact-disengagement during the translation process of the moving scroll disk 1, when the damping opening 331 between the two second damping parts 33 is too wide, it will increase the probability that the impact point of the damping component 3 and the damping component groove 11 is in the missing position, resulting in a reduction in the damping effect. Therefore, it is necessary to improve the included angle parameter of the damping opening 331.

[0050] To ensure that the impact point between the vibration damping component 3 and the vibration damping component groove 11 is located on the second vibration damping part 33, the included angle of the vibration damping part opening 331 between the two second vibration damping parts 33 is α. N represents the number of vibration damping component slots 11 in the moving scroll plate 1. In this embodiment, we take six vibration damping component slots 11 in the moving scroll plate 1 as an example. When there are six vibration damping component slots 11 in the moving scroll plate 1, the angle α is less than 60°. Only when the angle α is less than 60° can we ensure that the second vibration damping part 33 of the vibration damping component 3 contacts the vibration damping component slot 11 on the second vibration damping part 33 each time, thereby ensuring the vibration damping effect.

[0051] In one possible implementation, the number of vibration damping component slots 11 of the moving scroll disk 1 is N, where N≥3.

[0052] In this embodiment, the number of grooves 11 in the vibration damping component is improved to achieve the effect of limiting the rotation of the moving scroll disk 1. Specifically, the number of vibration damping component slots 11 of the moving scroll plate 1 is at least three. In this embodiment, six vibration damping component slots 11 are used as an example. The six vibration damping component slots 11 are evenly arranged along the circumferential direction on the side of the moving scroll plate 1 near the support assembly. Correspondingly, the support assembly 2 is provided with six cylindrical pins 21 on the side facing the moving scroll plate 1. The six cylindrical pins 21 are evenly arranged along the circumferential direction. During assembly, the vibration damping component 3 is inserted into the vibration damping component slot 11 of the moving scroll plate, and then the moving scroll plate 1 is installed on the crankshaft of the driver, so that the moving scroll plate 1 and the support assembly 2 provided in the driver housing form a clearance fit. At this time, each cylindrical pin 21 of the support assembly 2 is inserted into the corresponding vibration damping component slot 11 of the moving scroll plate 1. This allows the cylindrical pin 21 to restrict the rotation of the moving scroll plate 1, while the vibration damping component 3 in the vibration damping component slot of the moving scroll plate weakens the impact force between the cylindrical pin 21 and the moving scroll plate 1, thereby achieving the effect of reducing vibration and noise.

[0053] In one possible implementation, the cross-sectional shape of the second damping part 33 is one of a semicircle, ellipse, square, trapezoid, or triangle.

[0054] In this embodiment, the cross-sectional shape of the second vibration damping part 33 has been improved to ensure the vibration damping effect. Specifically, the cross-sectional shape of the second vibration damping part 33 includes, but is not limited to, a semicircle, ellipse, square, trapezoid, or triangle, as long as it can reduce the impact force and be stably engaged in the slot 12 of the vibration damping component groove 11 of the moving scroll plate, effectively suppressing the axial movement of the vibration damping component 3.

[0055] As can be seen from the above description, the beneficial effects of the present invention are as follows: by setting a vibration damping component between the moving scroll and the support assembly, the collision between the support assembly and the vibration damping component is reduced, as well as the collision between the vibration damping component and the moving scroll, thereby reducing the vibration and noise generated by the collision between the moving scroll and the support assembly, and effectively reducing the operating noise of the compressor.

[0056] The implementation principle of the vibration reduction structure for the moving scroll disk in this application embodiment is as follows:

[0057] During the operation of the moving scroll plate, the six cylindrical pins slide relative to the inner edges of the vibration damping components at their respective positions. Taking the operation of a single cylindrical pin as an example, when the cylindrical pin approaches the inner edge of the vibration damping component, it first contacts the first damping part of the component. The vibration generated by this contact collision is absorbed and mitigated by the rubber material of the first damping part. Then, the cylindrical pin pushes the vibration damping component towards the groove wall of the damping component. The second damping part then contacts the inner wall of the groove, where the vibration generated by this contact collision is also absorbed and mitigated by the rubber material of the second damping part. Thus, a single vibration damping component reduces two impact vibrations in one circumferential rotation. Simultaneously, the vibration damping component, driven by the pushing force of the cylindrical pins, rotates. The outer wall of the metal ring rotates relative to the groove wall of the vibration damping component, generating friction and thus suppressing the rotation of the moving scroll plate. To ensure the service life of the metal ring, wear-resistant metal materials, such as bearing steel, are preferably used, which effectively reduces wear and extends service life. During the rotation of the vibration damping component due to the pushing force of the cylindrical pin, the vibration damping component tends to move along the axial direction. At this time, the second vibration damping part not only plays a role in damping vibration but also restricts the axial displacement of the vibration damping component, preventing the metal ring from colliding with the support assembly and the moving scroll plate in the axial direction, thus effectively reducing noise.

[0058] This invention also relates to a scroll compressor, including the vibration damping structure for the moving scroll as described above. The key working components of the scroll compressor include a stationary scroll and a moving scroll meshing with and moving relative to it. The stationary scroll, fixed to the compressor housing, contacts the moving scroll, forming a crescent-shaped space between the sides of the scroll teeth. When the moving scroll performs a non-rotating rotary translational motion about the center of the stationary scroll, the crescent-shaped space moves from the outer ring to the inner ring and continuously shrinks, thereby achieving gas intake and compression.

[0059] N (N≥3) vibration damping component slots are evenly distributed along the circumference on the back of the moving scroll disk. The support assembly is set on the housing of the scroll compressor. The support assembly is provided with cylindrical pins that correspond to the positions of the vibration damping component slots. The vibration damping component slots are provided with annular vibration damping components, and the cylindrical pins extend into the inner side of the vibration damping components.

[0060] When the scroll compressor is running, the motor rotor drives the crankshaft to rotate, and the crankshaft drives the moving scroll plate to perform a non-rotating rotary translational motion around the center of the stationary scroll plate. Correspondingly, N (N≥3) cylindrical pins slide on the inner edge of the vibration damping component at the corresponding position, separating the groove wall of the vibration damping component from the cylindrical pins, thereby reducing the impact force between the groove wall of the vibration damping component of the moving scroll plate and the cylindrical pin, thus reducing vibration and noise.

[0061] In this embodiment, by applying the vibration damping structure for the moving scroll plate described above, the operating vibration and noise of the scroll compressor can be greatly reduced, thereby improving the product's competitiveness.

[0062] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

[0063] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
