Description

TECHNICAL FIELD

[0001] The utility model relates to a compressor equipment technical field, specifically, a kind of compressor and refrigeration equipment. BACKGROUND

[0002] At present, the refrigerator compressor in the related art is prone to resonance due to insufficient local stiffness of the shell, resulting in large resonance noise during operation of the compressor, affecting the reliability of the refrigerator and reducing the user experience. SUMMARY

[0003] Embodiments of the utility model aim to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of embodiments of the utility model provides a compressor.

[0005] A second aspect of embodiments of the utility model provides a refrigeration equipment.

[0006] Therefore, according to the first aspect of embodiments of the utility model, a compressor is provided, which comprises: a first shell; a second shell connected to the first shell and enclosing a containing cavity with the first shell; a vibration absorbing member provided on at least one of the first shell and the second shell and located in the containing cavity, the vibration absorbing member comprising: a plate body comprising opposite first and second sides; a cantilever structure provided on the first side and / or the second side, one end of the cantilever structure being connected to the plate body, the other end of the cantilever structure extending away from the plate body, the cantilever structure comprising a plurality of cantilevers, at least two cantilevers being spaced apart.

[0007] The compressor provided in the embodiments of the utility model comprises a first shell, a second shell and a vibration absorbing member. Specifically, the first shell and the second shell are connected, and the first shell and the second shell enclose a containing cavity. The vibration absorbing member is provided on the first shell, or the vibration absorbing member is provided on the second shell, or the first shell and the second shell are respectively provided with a vibration absorbing member. The vibration absorbing member can be set according to actual needs. The vibration absorbing member is located in the containing cavity. Optionally, the vibration absorbing member is welded to the inner wall of the first shell and / or the inner wall of the second shell. The plate body is provided with a welding point.

[0008] The vibration absorbing member comprises a plate body and a cantilever structure. The plate body comprises opposite first and second sides. Specifically, the cantilever structure is provided on the first side, or the cantilever structure is provided on the second side, or the number of cantilever structures is two, and the plate body is provided with a cantilever structure on each side. The cantilever structure can be set according to actual needs.

[0009] The cantilever structure comprises a plurality of cantilevers, and at least two cantilevers are arranged at intervals, that is, there is a spacing between the at least two cantilevers. By arranging the vibration absorbing member on the first shell and / or the second shell, and due to the presence of the plurality of cantilevers, the vibration generated by the first shell and / or the second shell during the operation of the compressor can be transmitted to the cantilever structure of the vibration absorbing member, thereby achieving the effect of absorbing vibration and reducing the vibration generated during the operation of the compressor. At the same time, since the vibration absorbing member has a certain mass, by arranging the vibration absorbing member on the first shell and / or the second shell, the local stiffness of the first shell or the second shell can be changed, thereby realizing the resonance frequency avoidance of the first shell or the second shell, effectively solving the resonance problem of the first shell and / or the second shell due to insufficient local stiffness, reducing the resonance noise during the operation of the compressor, improving the reliability of the compressor, and being beneficial to improving the user experience of the refrigeration equipment with the compressor.

[0010] It can be understood that the position of the vibration absorbing member on the first shell and / or the second shell is not fixed, and can be selected according to the internal space position, as long as interference with other structures in the accommodating cavity is avoided.

[0011] Optionally, the first shell comprises a first part and a second part, the curvature of the first part is smaller than the curvature of the second part, and in the case that the vibration absorbing member is arranged on the first shell, the vibration absorbing member is configured to be close to the first part. The second shell comprises a third part and a fourth part, the curvature of the third part is smaller than the curvature of the fourth part, and in the case that the vibration absorbing member is arranged on the second shell, the vibration absorbing member is configured to be close to the third part. It can be understood that the position with smaller curvature has poorer stiffness, and arranging the vibration absorbing member close to the area with poorer stiffness is beneficial to improving the vibration absorbing effect while improving the structural strength of the area.

[0012] Optionally, the two cantilever structures are symmetrically distributed on opposite sides of the plate body.

[0013] Optionally, the plate body and the cantilever structure are an integral structure.

[0014] Optionally, the first shell is an upper shell, and the second shell is a lower shell.

[0015] In addition, the compressor provided by the above technical scheme of the present application also has the following additional technical features:

[0016] In some technical schemes, the plate body is provided with a vibration absorbing groove, and at least a part of the cantilever structure is located in the vibration absorbing groove.

[0017] In the technical solution, the plate body is provided with a damping groove, and specifically, at least part of the cantilever structure is located in the damping groove, so that the vibration absorption effect is achieved, the local rigidity of the first shell or the second shell is changed, the resonance frequency of the first shell or the second shell is avoided, the resonance noise during the operation of the compressor is reduced, the occupied space of the cantilever structure is reduced, and interference between the cantilever structure and other structures in the accommodation cavity is avoided.

[0018] In some technical solutions, the damping groove comprises a first groove wall, a second groove wall and a third groove wall, the first groove wall is located between the second groove wall and the third groove wall, the cantilever structure is connected to the first groove wall, and the cantilever structure has a first gap with at least one of the second groove wall and the third groove wall.

[0019] In the technical solution, the damping groove comprises a first groove wall, a second groove wall and a third groove wall, and specifically, the first groove wall is located between the second groove wall and the third groove wall, that is, the first groove wall is a groove bottom wall, and the second groove wall and the third groove wall are groove side walls.

[0020] The cantilever structure is connected to the first groove wall, and the cantilever structure has a first gap between the second groove wall and / or the third groove wall, so that the occupied space of the cantilever structure is reduced, interference between the cantilever structure and other structures in the accommodation cavity is avoided, and the vibration absorption effect of the vibration absorption member is improved.

[0021] In some technical solutions, the cantilever structure comprises a reinforcing portion, the reinforcing portion is connected to the plate body, and the plurality of cantilevers are arranged on the reinforcing portion.

[0022] In the technical solution, the cantilever structure comprises a reinforcing portion, and specifically, the reinforcing portion is connected to the plate body, and the plurality of cantilevers are arranged on the reinforcing portion, that is, the plurality of cantilevers are connected to the plate body through the reinforcing portion, so that the vibration absorption and noise reduction during the operation of the compressor are achieved, the structural strength of the plurality of cantilevers is improved, and the service life of the vibration absorption member is prolonged.

[0023] In addition, since the reinforcing portion is arranged, the length of the cantilever can be correspondingly reduced, so that the problem of too weak structural rigidity of the cantilever due to too long length of the cantilever is avoided, and the problem of too large vibration amplitude of the cantilever is avoided.

[0024] In some technical solutions, the at least two cantilevers are connected.

[0025] In the technical solution, the at least two cantilevers are connected, so that the vibration generated by the first shell and / or the second shell during the operation of the compressor can be transmitted to the cantilever structure, the vibration absorption effect is achieved, the structural rigidity of the cantilever as a whole is improved, and the problem of too large vibration amplitude of the cantilever is avoided.

[0026] Furthermore, since connecting at least two cantilevers can improve the overall structural stiffness of the cantilevers, the length of the cantilevers can be increased accordingly, which is beneficial to improving the vibration absorption effect.

[0027] In some technical solutions, optionally, the multiple cantilever arms include a first cantilever arm and a second cantilever arm. The first end of the first cantilever arm is connected to the plate body, and the second end of the first cantilever arm extends away from the plate body. The first end of the second cantilever arm is connected to the second end of the first cantilever arm, and the second end of the second cantilever arm extends toward the side where the plate body is located.

[0028] In this technical solution, multiple cantilever arms are defined, including a first cantilever arm and a second cantilever arm. Specifically, the first end of the first cantilever arm is connected to the plate, the second end of the first cantilever arm extends away from the plate, the first end of the second cantilever arm is connected to the second end of the first cantilever arm, and the second end of the second cantilever arm extends toward the side where the plate is located. This can absorb the vibration generated by the first shell and / or the second shell, achieve resonance frequency avoidance, and reduce the space occupied by multiple cantilever arms in the cavity, thereby avoiding interference with other structures in the cavity.

[0029] In addition, since the first and second cantilever arms are connected, it helps to improve the overall structural stiffness of the cantilever arms and avoid excessive vibration amplitude of the cantilever arms.

[0030] In some technical solutions, optionally, there is a second gap between the second end of the second cantilever and the plate.

[0031] In this technical solution, since there is a second gap between the second end of the second cantilever and the plate, it is beneficial to improve the vibration absorption effect of the damping component, reduce the vibration generated during the operation of the compressor, thereby reducing vibration noise and improving the user's experience of using the refrigeration equipment with the compressor.

[0032] In some technical solutions, the multiple cantilever may optionally include a third cantilever and a fourth cantilever, the fourth cantilever being located on the side of the third cantilever closer to the second cantilever, the first end of the third cantilever being connected to the plate, the second end of the third cantilever extending away from the plate, the first end of the fourth cantilever being connected to the second end of the third cantilever, and the second end of the fourth cantilever extending toward the side where the plate is located.

[0033] In this technical solution, the multiple cantilever arms include a third and a fourth cantilever arm. Specifically, the first end of the third cantilever arm is connected to the plate, and the second end of the third cantilever arm extends away from the plate. The first end of the fourth cantilever arm is connected to the second end of the third cantilever arm, and the second end of the fourth cantilever arm extends towards the side where the plate is located. This allows for the absorption of vibrations generated by the first and / or second shells, achieving resonance frequency avoidance, while reducing the space occupied by the multiple cantilever arms within the cavity, thereby avoiding interference with other structures within the cavity. Furthermore, the connection between the third and fourth cantilever arms helps improve the overall structural stiffness of the cantilever arms and prevents excessive cantilever vibration amplitude.

[0034] In addition, during compressor operation, when the vibration on the first housing and / or the second housing is transmitted to the cantilever structure, the vibration between the first cantilever, the second cantilever, the third cantilever and the fourth cantilever can be partially canceled out, thus avoiding excessive cantilever vibration amplitude.

[0035] In some technical solutions, optionally, the second end of the fourth cantilever is connected to the second end of the second cantilever.

[0036] In this technical solution, since the fourth cantilever is connected to the second cantilever, the overall structural stiffness of the cantilever structure can be further improved. While absorbing the vibration generated by the first shell and / or the second shell and achieving resonance frequency avoidance, the vibration amplitude of the cantilever structure is avoided to be too large.

[0037] In some technical solutions, optionally, the multiple cantilever arms also include a fifth cantilever arm, one end of which is connected to the second end of the second cantilever arm and / or the second end of the fourth cantilever arm, and the other end of the fifth cantilever arm extends away from the plate.

[0038] In this technical solution, multiple cantilever arms are defined, including a fifth cantilever arm. Specifically, one end of the fifth cantilever arm is connected to the second and / or fourth cantilever arms, and the other end extends away from the plate. This can improve the vibration absorption effect, reduce the vibration noise during compressor operation, and further improve the overall structural rigidity of the cantilever structure, thus avoiding excessive vibration amplitude of the cantilever structure.

[0039] In some technical solutions, the vibration absorber is optionally constructed as an arc-shaped vibration absorber; the inner wall of at least one of the first housing and the second housing is constructed as an arc-shaped wall, and the arc of the arc-shaped vibration absorber is smaller than the arc of the arc-shaped wall.

[0040] In this technical solution, since the vibration absorber is an arc-shaped vibration absorber, specifically, when the vibration absorber is mounted on the first housing, the curvature of the arc-shaped vibration absorber is smaller than the curvature of the inner wall of the first housing. When the vibration absorber is mounted on the second housing, the curvature of the arc-shaped vibration absorber is smaller than the curvature of the inner wall of the second housing. In other words, the two sides of the arc-shaped vibration absorber are raised relative to the inner wall of the first or second housing, facilitating welding and fixing of the vibration absorber to the first or second housing, and improving the installation efficiency of the compressor.

[0041] In some technical solutions, the vibration-absorbing element optionally includes a first wall surface and a second wall surface facing away from each other, wherein the first wall surface is closer to the inner wall of the first housing or the inner wall of the second housing than the second wall surface; the maximum gap between the first wall surface and the inner wall of the first housing is less than 0.5 mm based on the vibration-absorbing element being disposed in the first housing; and the maximum gap between the first wall surface and the inner wall of the second housing is less than 0.5 mm based on the vibration-absorbing element being disposed in the second housing.

[0042] In this technical solution, the vibration-absorbing element is defined to include a first wall surface and a second wall surface that are opposite to each other. Specifically, the first wall surface is closer to the inner wall of the first housing or the inner wall of the second housing than the second wall surface.

[0043] Specifically, when the vibration absorber is installed on the first housing, the maximum gap L1 between the first wall of the vibration absorber and the inner wall of the first housing is less than 0.5mm. This facilitates welding and fixing between the vibration absorber and the first housing, while ensuring that the vibration generated by the first housing can be transmitted to the vibration absorber, thus ensuring the vibration absorption effect of the vibration absorber on the first housing and reducing the vibration noise during compressor operation.

[0044] When the vibration absorber is installed on the second housing, the maximum gap L2 between the first wall of the vibration absorber and the inner wall of the second housing is less than 0.5mm. This facilitates welding and fixing between the vibration absorber and the second housing, while ensuring that the vibration generated by the second housing can be transmitted to the vibration absorber, thus ensuring the vibration absorption effect of the vibration absorber on the second housing and reducing the vibration noise during compressor operation.

[0045] In some technical solutions, optionally, there are multiple vibration-absorbing elements, with at least one vibration-absorbing element disposed in the first housing and at least one vibration-absorbing element disposed in the second housing.

[0046] In this technical solution, the number of vibration-absorbing components is limited to multiple. Specifically, at least one vibration-absorbing component is installed on the first housing. Due to the presence of multiple cantilever arms, the vibration generated by the first housing can be transmitted to the cantilever structure of the vibration-absorbing component during the operation of the compressor, thereby achieving the effect of vibration absorption. At the same time, since the vibration-absorbing component has a certain mass, it can change the local stiffness of the first housing, thereby realizing the resonance avoidance of the first housing and effectively solving the resonance problem caused by insufficient local stiffness of the first housing.

[0047] At least one vibration-absorbing element is installed on the second housing. Due to the presence of multiple cantilever arms, the vibration generated by the second housing during compressor operation can be transmitted to the cantilever structure of the vibration-absorbing element, thereby achieving the vibration absorption effect. At the same time, since the vibration-absorbing element has a certain mass, it can change the local stiffness of the second housing, thereby achieving resonance frequency avoidance of the second housing and effectively solving the resonance problem caused by insufficient local stiffness of the second housing.

[0048] Since at least one vibration-absorbing element is provided on the first housing and the second housing respectively, it is beneficial to improve the overall vibration absorption effect, significantly improve the vibration generated by the compressor during operation, and effectively solve the resonance problem caused by insufficient local stiffness of the first housing and the second housing, reduce the resonance noise during compressor operation, and improve the reliability of the compressor.

[0049] In some technical solutions, optionally, at least two vibration-absorbing elements are disposed in the second housing, and the at least two vibration-absorbing elements are respectively located on opposite sides of the receiving cavity.

[0050] In this technical solution, at least two vibration-absorbing elements are provided in the second housing. Specifically, at least two vibration-absorbing elements are located on opposite sides of the receiving cavity, thereby improving the vibration absorption effect, reducing the vibration noise during compressor operation, improving the local stiffness of the second housing, achieving resonance avoidance, and preventing the at least two vibration-absorbing elements from interfering with other structures in the receiving cavity.

[0051] According to a second aspect of this utility model, a refrigeration device is provided, including a compressor as provided in any of the above technical solutions, and thus possesses all the beneficial technical effects of the compressor, which will not be repeated here.

Detailed Implementation

[0063] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0064] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0065] The following reference Figures 1 to 7 This invention describes a compressor 100 and a refrigeration device provided according to some embodiments of the present invention.

[0066] In one embodiment according to this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, a compressor 100 is proposed, comprising: a first housing 110; a second housing 120 connected to the first housing 110 and enclosing the first housing 110 to form a receiving cavity 130; and a vibration-absorbing member 140 disposed on at least one of the first housing 110 and the second housing 120 and located within the receiving cavity 130. The vibration-absorbing member 140 comprises: a plate 141, the plate 141 including opposing first sides 180 and second sides 190; and a cantilever structure 142 disposed on the first side 180 and / or the cantilever structure 142 disposed on the second side 190. One end of the cantilever structure 142 is connected to the plate 141, and the other end of the cantilever structure 142 extends away from the plate 141. The cantilever structure 142 includes a plurality of cantilever arms 150, with at least two cantilever arms 150 spaced apart.

[0067] The compressor 100 provided in this embodiment of the present invention includes a first housing 110, a second housing 120, and a vibration-absorbing member 140. Specifically, the first housing 110 and the second housing 120 are connected, and the first housing 110 and the second housing 120 enclose a receiving cavity 130. The vibration-absorbing member 140 is disposed on the first housing 110, or on the second housing 120, or each of the first housing 110 and the second housing 120 is provided with a vibration-absorbing member 140. The specific configuration can be determined according to actual needs. The vibration-absorbing member 140 is located within the receiving cavity 130. Optionally, the vibration-absorbing member 140 is welded to the inner wall 131 of the first housing 110, and / or the vibration-absorbing member 140 is welded to the inner wall 131 of the second housing 120. Welding points are provided on the plate 141.

[0068] The vibration absorber 140 includes a plate 141 and a cantilever structure 142. The plate 141 includes a first side 180 (e.g., the left side) and a second side 190 (e.g., the right side) facing each other. Specifically, the cantilever structure 142 is disposed on the first side 180, or the cantilever structure 142 is disposed on the second side 190, or there are two cantilever structures 142, with cantilever structures 142 respectively disposed on opposite sides of the plate 141. The specific configuration can be made according to actual needs.

[0069] The cantilever structure 142 includes multiple cantilever arms 150, with at least two cantilever arms 150 spaced apart, meaning there is a gap between at least two cantilever arms 150. By providing vibration-absorbing members 140 on the first housing 110 and / or the second housing 120, and due to the presence of multiple cantilever arms 150, the vibrations generated by the first housing 110 and / or the second housing 120 can be transmitted to the cantilever structure 142 of the vibration-absorbing members 140 during the operation of the compressor 100, thereby achieving the effect of vibration absorption and reducing the vibration generated during the operation of the compressor 100. Meanwhile, since the vibration damping component has a certain mass, by setting the vibration absorbing component 140 on the first housing 110 and / or the second housing 120, the local stiffness of the first housing 110 or the second housing 120 can be changed, thereby realizing the resonance avoidance of the first housing 110 or the second housing 120, effectively solving the resonance problem caused by insufficient local stiffness of the first housing 110 and / or the second housing 120, reducing the resonance noise during the operation of the compressor 100, improving the reliability of the compressor 100, and helping to improve the user's experience of using the refrigeration equipment with the compressor 100.

[0070] It is understandable that the position of the vibration absorber 140 on the first housing 110 and / or the second housing 120 is not fixed, and can be selected according to the internal space position to avoid interference with other structures in the receiving cavity 130.

[0071] Optionally, the first housing 110 includes a first portion and a second portion, where the curvature of the first portion is smaller than that of the second portion. When the vibration-absorbing member 140 is disposed on the first housing 110, the vibration-absorbing member 140 is configured close to the first portion. The second housing 120 includes a third portion and a fourth portion, where the curvature of the third portion is smaller than that of the fourth portion. When the vibration-absorbing member 140 is disposed on the second housing 120, the vibration-absorbing member 140 is configured close to the third portion. It is understood that the area with smaller curvature has poorer stiffness. Placing the vibration-absorbing member 140 close to the area with poorer stiffness can improve the structural strength of that area and thus enhance the vibration reduction effect.

[0072] Optionally, the extension directions of at least two cantilever 150 are parallel to each other.

[0073] Optionally, two cantilever structures 142 are symmetrically distributed on opposite sides of the plate 141.

[0074] Optionally, the plate 141 and the cantilever structure 142 are an integral structure.

[0075] Optionally, the first housing 110 is the upper housing, and the second housing 120 is the lower housing.

[0076] like Figure 1As shown, in some embodiments, optionally, the plate 141 is provided with a vibration damping groove 143, and at least a portion of the cantilever structure 142 is located within the vibration damping groove 143.

[0077] In this embodiment, the plate 141 is provided with a vibration damping groove 143. Specifically, at least part of the cantilever structure 142 is located in the vibration damping groove 143, thereby absorbing vibration, changing the local stiffness of the first housing 110 or the second housing 120, realizing resonance frequency avoidance of the first housing 110 or the second housing 120, reducing the resonance noise during the operation of the compressor 100, and reducing the space occupied by the cantilever structure 142, thereby avoiding interference between the cantilever structure 142 and other structures in the receiving cavity 130.

[0078] Optionally, there are two vibration damping grooves 143, one of which is located on the first side 180 and the other is located on the second side 190. There are two cantilever structures 142, which are located in the two vibration damping grooves 143 respectively, that is, the plate 141 is an I-shaped structure.

[0079] like Figure 1 As shown, in some embodiments, optionally, the vibration damping groove 143 includes a first groove wall 144, a second groove wall 145, and a third groove wall 146, with the first groove wall 144 located between the second groove wall 145 and the third groove wall 146; wherein, the cantilever structure 142 is connected to the first groove wall 144 and has a first gap 160 with at least one of the second groove wall 145 and the third groove wall 146.

[0080] In this embodiment, the vibration damping groove 143 is defined to include a first groove wall 144, a second groove wall 145 and a third groove wall 146. Specifically, the first groove wall 144 is located between the second groove wall 145 and the third groove wall 146, that is, the first groove wall 144 is the bottom wall of the groove, and the second groove wall 145 and the third groove wall 146 are the side walls of the groove.

[0081] The cantilever structure 142 is connected to the first groove wall 144, and there is a first gap 160 between the cantilever structure 142 and the second groove wall 145 and / or the third groove wall 146. This reduces the space occupied by the cantilever structure 142 and avoids interference between the cantilever structure 142 and other structures in the receiving cavity 130, while improving the vibration absorption effect of the vibration absorber 140.

[0082] like Figure 1 As shown, in some embodiments, the cantilever structure 142 may optionally include a reinforcing part 147 connected to the plate 141, and a plurality of cantilever arms 150 disposed on the reinforcing part 147.

[0083] In this embodiment, the cantilever structure 142 is defined to include a reinforcing part 147. Specifically, the reinforcing part 147 is connected to the plate 141, and multiple cantilevers 150 are disposed on the reinforcing part 147. That is, the multiple cantilevers 150 are connected to the plate 141 through the reinforcing part 147, thereby achieving vibration absorption and noise reduction during the operation of the compressor 100, while also improving the structural strength of the multiple cantilevers 150 and extending the service life of the vibration-absorbing component 140.

[0084] Furthermore, by providing the reinforcing part 147, the length of the cantilever 150 can be reduced accordingly, thus avoiding the problem that the structural stiffness of the cantilever 150 is too weak due to its long length, which in turn causes the cantilever 150 to vibrate too much.

[0085] like Figure 2 As shown, in some embodiments, optionally, at least two cantilever 150s are connected.

[0086] In this embodiment, since at least two cantilever 150s are connected, the vibrations generated by the first housing 110 and / or the second housing 120 can be transmitted to the cantilever structure 142 during the operation of the compressor 100, thereby achieving a vibration absorption effect and improving the overall structural rigidity of the cantilever 150, thus preventing the cantilever 150 from vibrating too much.

[0087] Furthermore, since connecting at least two cantilever 150s can improve the overall structural stiffness of the cantilever 150, the length of the cantilever 150 can be increased accordingly, which is beneficial to improving the vibration absorption effect.

[0088] like Figure 2 As shown, in some embodiments, optionally, the plurality of cantilever 150 includes a first cantilever 151 and a second cantilever 152. The first end of the first cantilever 151 is connected to the plate 141, and the second end of the first cantilever 151 extends away from the plate 141. The first end of the second cantilever 152 is connected to the second end of the first cantilever 151, and the second end of the second cantilever 152 extends toward the side where the plate 141 is located.

[0089] In this embodiment, multiple cantilever 150 are defined, including a first cantilever 151 and a second cantilever 152. Specifically, the first end of the first cantilever 151 is connected to the plate 141, and the second end of the first cantilever 151 extends away from the plate 141. The first end of the second cantilever 152 is connected to the second end of the first cantilever 151, and the second end of the second cantilever 152 extends toward the side where the plate 141 is located. This allows the absorption of vibrations generated by the first housing 110 and / or the second housing 120, achieving resonance frequency avoidance, while reducing the space occupied by the multiple cantilever 150 in the receiving cavity 130, thereby avoiding interference with other structures in the receiving cavity 130.

[0090] In addition, since the first cantilever 151 and the second cantilever 152 are connected, it is beneficial to improve the overall structural stiffness of the cantilever 150 and avoid excessive vibration amplitude of the cantilever 150.

[0091] like Figure 2 As shown, in some embodiments, optionally, a second gap 170 is provided between the second end of the second cantilever 152 and the plate 141.

[0092] In this embodiment, since there is a second gap 170 between the second end of the second cantilever 152 and the plate 141, it is beneficial to improve the vibration absorption effect of the damping component, reduce the vibration generated during the operation of the compressor 100, thereby reducing vibration noise and improving the user's experience of using the refrigeration equipment with the compressor 100.

[0093] like Figure 2 As shown, in some embodiments, optionally, the plurality of cantilever 150 further includes a third cantilever 153 and a fourth cantilever 154, the fourth cantilever 154 being located on the side of the third cantilever 153 near the second cantilever 152, the first end of the third cantilever 153 being connected to the plate 141, the second end of the third cantilever 153 extending away from the plate 141, the first end of the fourth cantilever 154 being connected to the second end of the third cantilever 153, and the second end of the fourth cantilever 154 extending toward the side where the plate 141 is located.

[0094] In this embodiment, the multiple cantilever 150 includes a third cantilever 153 and a fourth cantilever 154. Specifically, the first end of the third cantilever 153 is connected to the plate 141, and the second end of the third cantilever 153 extends away from the plate 141. The first end of the fourth cantilever 154 is connected to the second end of the third cantilever 153, and the second end of the fourth cantilever 154 extends towards the side where the plate 141 is located. This allows for the absorption of vibrations generated by the first housing 110 and / or the second housing 120, achieving resonance frequency avoidance, while reducing the space occupied by the multiple cantilever 150 within the receiving cavity 130, thereby avoiding interference with other structures within the receiving cavity 130. Furthermore, since the third cantilever 153 and the fourth cantilever 154 are connected, it helps to improve the overall structural stiffness of the cantilever 150 and prevents excessive vibration amplitude of the cantilever 150.

[0095] In addition, during the operation of the compressor 100, when the vibration on the first housing 110 and / or the second housing 120 is transmitted to the cantilever structure 142, the vibration between the first cantilever 151, the second cantilever 152, the third cantilever 153 and the fourth cantilever 154 can be partially canceled out, thus avoiding excessive vibration amplitude of the cantilever 150.

[0096] like Figure 2 As shown, in some embodiments, optionally, the second end of the fourth cantilever 154 is connected to the second end of the second cantilever 152.

[0097] In this embodiment, since the fourth cantilever 154 is connected to the second cantilever 152, the overall structural stiffness of the cantilever structure 142 can be further improved. While absorbing the vibration generated by the first shell 110 and / or the second shell 120 and achieving resonance frequency avoidance, the vibration amplitude of the cantilever structure 142 is avoided to be too large.

[0098] like Figure 2 As shown, in some embodiments, optionally, the plurality of cantilever 150 further includes a fifth cantilever 155, one end of which is connected to the second end of the second cantilever 152 and / or the second end of the fourth cantilever 154, and the other end of the fifth cantilever 155 extends in a direction away from the plate 141.

[0099] In this embodiment, the multiple cantilever 150 includes a fifth cantilever 155. Specifically, one end of the fifth cantilever 155 is connected to the second cantilever 152 and / or the fourth cantilever 154, and the other end extends away from the plate 141. This can improve the vibration absorption effect, reduce the vibration noise during the operation of the compressor 100, and further improve the overall structural rigidity of the cantilever structure 142, thus avoiding excessive vibration amplitude of the cantilever structure 142.

[0100] In some embodiments, the vibration absorber 140 is optionally configured as an arc-shaped vibration absorber; the inner wall 131 of at least one of the first housing 110 and the second housing 120 is configured as an arc-shaped wall, and the arc of the arc-shaped vibration absorber is smaller than the arc of the arc-shaped wall.

[0101] In this embodiment, since the vibration absorber 140 is an arc-shaped vibration absorber, specifically, when the vibration absorber 140 is disposed on the first housing 110, the curvature of the arc-shaped vibration absorber is smaller than the curvature of the inner wall 131 of the first housing 110. When the vibration absorber 140 is disposed on the second housing 120, the curvature of the arc-shaped vibration absorber is smaller than the curvature of the inner wall 131 of the second housing 120. That is to say, the two sides of the arc-shaped vibration absorber are raised relative to the inner wall 131 of the first housing 110 or the inner wall 131 of the second housing 120, which facilitates the welding and fixing of the vibration absorber 140 to the first housing 110 or the second housing 120, and helps to improve the installation efficiency of the compressor 100.

[0102] like Figure 4 and Figure 6As shown, in some embodiments, optionally, the vibration absorber 140 includes a first wall surface 148 and a second wall surface 149 facing away from each other, wherein the first wall surface 148 is closer to the inner wall 131 of the first housing 110 or the inner wall 131 of the second housing 120 than the second wall surface 149; based on the vibration absorber 140 being disposed in the first housing 110, the maximum gap between the first wall surface 148 and the inner wall 131 of the first housing 110 is less than 0.5 mm; based on the vibration absorber 140 being disposed in the second housing 120, the maximum gap between the first wall surface 148 and the inner wall 131 of the second housing 120 is less than 0.5 mm.

[0103] In this embodiment, the vibration damping member 140 is defined to include a first wall surface 148 and a second wall surface 149 facing away from each other. Specifically, the first wall surface 148 is closer to the inner wall 131 of the first housing 110 or the inner wall 131 of the second housing 120 than the second wall surface 149.

[0104] Specifically, when the vibration absorber 140 is disposed on the first housing 110, the maximum gap L1 between the first wall surface 148 of the vibration absorber 140 and the inner wall 131 of the first housing 110 is less than 0.5mm. This facilitates welding and fixing between the vibration absorber 140 and the first housing 110, while ensuring that the vibration generated by the first housing 110 can be transmitted to the vibration absorber 140, that is, ensuring the vibration absorption effect of the vibration absorber 140 on the first housing 110, thereby reducing the vibration noise of the compressor 100 during operation.

[0105] When the vibration absorber 140 is installed on the second housing 120, the maximum gap L2 between the first wall surface 148 of the vibration absorber 140 and the inner wall 131 of the second housing 120 is less than 0.5mm. This facilitates welding and fixing between the vibration absorber 140 and the second housing 120, while ensuring that the vibration generated by the second housing 120 can be transmitted to the vibration absorber 140, that is, ensuring the vibration absorption effect of the vibration absorber 140 on the second housing 120, thereby reducing the vibration noise of the compressor 100 during operation.

[0106] like Figure 3 , Figure 5 and Figure 7 As shown, in some embodiments, optionally, there are multiple vibration-absorbing elements 140, with at least one vibration-absorbing element 140 disposed in the first housing 110 and at least one vibration-absorbing element 140 disposed in the second housing 120.

[0107] In this embodiment, the number of vibration-absorbing elements 140 is limited to multiple. Specifically, at least one vibration-absorbing element 140 is disposed on the first housing 110. Due to the presence of multiple cantilever 150, the vibration generated by the first housing 110 can be transmitted to the cantilever structure 142 of the vibration-absorbing element 140 during the operation of the compressor 100, thereby achieving the effect of vibration absorption. At the same time, since the vibration-absorbing element has a certain mass, it can change the local stiffness of the first housing 110, thereby realizing the resonance avoidance of the first housing 110 and effectively solving the resonance problem caused by insufficient local stiffness of the first housing 110.

[0108] At least one vibration-absorbing element 140 is disposed on the second housing 120. Due to the presence of multiple cantilever structures 150, the vibration generated by the second housing 120 during the operation of the compressor 100 can be transmitted to the cantilever structure 142 of the vibration-absorbing element 140, thereby achieving the effect of vibration absorption. At the same time, since the vibration-absorbing element has a certain mass, it can change the local stiffness of the second housing 120, thereby achieving resonance frequency avoidance of the second housing 120 and effectively solving the resonance problem caused by insufficient local stiffness of the second housing 120.

[0109] Since at least one vibration-absorbing element 140 is provided on the first housing 110 and the second housing 120 respectively, it is beneficial to improve the overall vibration absorption effect, significantly improve the vibration generated by the compressor 100 during operation, and effectively solve the resonance problem caused by insufficient local stiffness of the first housing 110 and the second housing 120, reduce the resonance noise during the operation of the compressor 100, and improve the reliability of the compressor 100.

[0110] like Figure 5 As shown, in some embodiments, optionally, at least two vibration-absorbing elements 140 are disposed on the second housing 120, and the at least two vibration-absorbing elements 140 are respectively located on opposite sides of the receiving cavity 130.

[0111] In this embodiment, at least two vibration-absorbing elements 140 are provided in the second housing 120. Specifically, at least two vibration-absorbing elements 140 are located on opposite sides of the receiving cavity 130, thereby improving the vibration absorption effect, reducing the vibration noise of the compressor 100 during operation, improving the local stiffness of the second housing 120, achieving resonance frequency avoidance, and preventing the at least two vibration-absorbing elements from interfering with other structures in the receiving cavity 130.

[0112] In one specific embodiment, the compressor housing (compressor 100) has an upper housing (first housing 110) and a lower housing (second housing 120). A vibration-absorbing plate (vibration-absorbing element 140) is welded to the top of the upper housing, and vibration-absorbing plates (vibration-absorbing elements 140) are welded to both sides of the lower housing. The vibration-absorbing plates (vibration-absorbing elements 140) have weld points in the middle and are welded to the housing (first housing 110 and / or second housing 120). The position of the vibration-absorbing plate welded to the housing is not fixed and is selected according to the internal space to avoid interference with the internal structure. After the vibration-absorbing plate is welded to the housing, the maximum gaps L1 and L2 between the vibration-absorbing plate and the housing (the inner wall 131 of the first housing 110 and / or the inner wall 131 of the second housing 120) are both less than 0.5 mm. By welding vibration-absorbing plates (vibration-absorbing elements 140) to the housing (first housing 110 and / or second housing 120), the resonance problem caused by insufficient local stiffness of the housing is solved, achieving noise reduction and vibration absorption.

[0113] By adding vibration-absorbing plates (vibration-absorbing elements 140) to the first housing 110 and / or the second housing 120, high-frequency noise can be significantly improved and the resonance noise of the housing (first housing 110 and / or second housing 120) can be reduced.

[0114] According to a second aspect of the present invention, a refrigeration device is provided, including a compressor 100 as provided in any of the above embodiments, and thus possessing all the beneficial technical effects of the compressor 100, which will not be repeated here.

[0115] Alternatively, the refrigeration equipment may include refrigerators, air conditioners, or freezers.

[0116] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, specifically, the compressor 100 includes a first housing 110, a second housing 120, and a vibration-absorbing member 140. Specifically, the first housing 110 and the second housing 120 are connected, and the first housing 110 and the second housing 120 enclose a receiving cavity 130. The vibration-absorbing member 140 is disposed on the first housing 110, or on the second housing 120, or both the first housing 110 and the second housing 120 are respectively provided with vibration-absorbing members 140. The specific configuration can be determined according to actual needs. The vibration-absorbing member 140 is located within the receiving cavity 130. Optionally, the vibration-absorbing member 140 is welded to the inner wall 131 of the first housing 110, and / or the vibration-absorbing member 140 is welded to the inner wall 131 of the second housing 120. Welding points are provided on the plate 141.

[0117] The vibration absorber 140 includes a plate 141 and a cantilever structure 142. The plate 141 includes a first side 180 (e.g., the left side) and a second side 190 (e.g., the right side) facing each other. Specifically, the cantilever structure 142 is disposed on the first side 180, or the cantilever structure 142 is disposed on the second side 190, or there are two cantilever structures 142, with cantilever structures 142 respectively disposed on opposite sides of the plate 141. The specific configuration can be made according to actual needs.

[0118] The cantilever structure 142 includes multiple cantilever arms 150, with at least two cantilever arms 150 spaced apart, meaning there is a gap between at least two cantilever arms 150. By providing vibration-absorbing members 140 on the first housing 110 and / or the second housing 120, and due to the presence of multiple cantilever arms 150, the vibrations generated by the first housing 110 and / or the second housing 120 can be transmitted to the cantilever structure 142 of the vibration-absorbing members 140 during the operation of the compressor 100, thereby achieving the effect of vibration absorption and reducing the vibration generated during the operation of the compressor 100. Meanwhile, since the vibration damping component has a certain mass, by setting the vibration absorbing component 140 on the first housing 110 and / or the second housing 120, the local stiffness of the first housing 110 or the second housing 120 can be changed, thereby realizing the resonance avoidance of the first housing 110 or the second housing 120, effectively solving the resonance problem caused by insufficient local stiffness of the first housing 110 and / or the second housing 120, reducing the resonance noise during the operation of the compressor 100, improving the reliability of the compressor 100, and helping to improve the user's experience of using the refrigeration equipment with the compressor 100.
