Description

Technical Field

[0001] This utility model relates to the field of compressor noise reduction technology, and in particular to a vibration reduction structure for compressors and a compressor. Background Technology

[0002] Compressors are commonly found in some electromechanical devices to meet refrigeration needs. Examples include refrigerators and other household appliances with refrigeration systems. Compressors are typically mounted on a mounting plate inside the device to ensure structural stability during operation. However, during operation, compressors can experience lateral vibrations due to factors such as internal piston movement or airflow impact.

[0003] Currently, the vibration reduction method used for compressors involves placing rubber vibration damping pads between the compressor and its mounting plate to absorb some vibration displacement, thereby reducing vibration noise. However, rubber vibration damping pads are insufficient in their vibration reduction effect and are prone to aging, resulting in limited vibration reduction performance and significant noise levels during compressor operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology, which uses rubber damping pads to dampen the compressor, resulting in limited damping effect and high compressor operating noise.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] In a first aspect, this utility model provides a vibration damping structure for a compressor, comprising a base, rollers, and a top cover. The base is mounted on a compressor mounting plate, and an annular support platform is formed on the base, extending from the side of the base away from the base. A plurality of rollers are disposed on the annular support platform and spaced circumferentially along the platform. The cross-sectional shape of each roller is circular in a direction perpendicular to the platform. The top cover is located at the top of the base and extends at least partially to the side of the rollers opposite the annular support platform, forming an installation gap with the top cover for connecting a compressor extension plate.

[0007] The vibration damping structure for compressors provided by this utility model connects a base to a compressor mounting plate and forms an annular support platform on the base. Multiple circular rollers are arranged axially at intervals on the annular support platform. A top cover is provided at the top of the base, creating an installation gap between the top cover and the rollers for connecting the compressor extension plate. In this way, when the compressor body vibrates laterally relative to the compressor mounting plate, the lateral movement of the extension plate relative to the base can be converted into rolling movement of the rollers between the two, thereby effectively attenuating the vibration transmission between the compressor and the compressor mounting plate, reducing the lateral amplitude of the compressor. Furthermore, the rollers can convert the lateral movement of the extension plate into rolling movement between the two, avoiding direct contact and friction that would generate noise. Compared with traditional rubber pad vibration damping methods, the vibration damping structure has a longer service life and is more reliable in use.

[0008] Preferably, the upper cover includes a body portion and an abutment portion. The body portion is connected to the base. The abutment portion is located on the side of the body portion facing the annular support platform and extends in a ring shape along the circumference of the body portion. The width of the abutment portion gradually decreases in the direction perpendicular to the annular support platform.

[0009] This design ensures a good connection between the top cover and the base. Furthermore, by gradually reducing the width of the abutment portion towards the annular support platform, the contact area is minimized when the abutment portion needs to contact the compressor's extension plate, thereby controlling the friction between the top cover and the compressor's extension plate to a minimum.

[0010] Preferably, along the direction perpendicular to the annular support platform, the outline of the bottom surface of the abutment is an arc; the inner edge of the bottom surface smoothly connects with the inner surface of the abutment, and the outer edge of the bottom surface smoothly connects with the outer surface of the abutment.

[0011] This design further reduces the area where the contact part may come into contact with the compressor's extension plate, thereby further reducing the degree of friction that may occur between the contact part and the compressor.

[0012] Preferably, the upper cover and the base are detachably connected to facilitate the connection of the compressor's extension plate and the vibration damping structure.

[0013] Preferably, the upper surface of the annular support platform is formed with an arc-shaped support surface, the roller is located at the position of the arc-shaped support surface, and the outer surface of the roller matches the arc-shaped support surface in a direction perpendicular to the annular support platform.

[0014] This configuration allows for better cooperation between the rollers and the annular support platform, enabling the rollers to maintain a stable position on the annular support platform.

[0015] Preferably, the roller is a spherical structure; and / or, the roller is a cylindrical structure, and the central axis of the cylindrical structure is an arc, the curvature of which is the same as the arc of the annular support platform.

[0016] This configuration allows the rollers to have a larger contact line or contact surface with the annular support platform and the compressor's extension plate, making the rollers more stable when transmitting movement caused by lateral vibration, thus achieving better vibration reduction and noise reduction effects.

[0017] Secondly, this utility model provides a compressor, which includes the vibration damping structure for the compressor as described above.

[0018] Preferably, the compressor includes a compressor body and a compressor base plate, the compressor body being disposed on the compressor base plate; the compressor body is further provided with an extension plate, the extension plate extending from the side of the compressor body in a direction away from the compressor body, and the vibration damping structure being sandwiched between the extension plate and the compressor base plate.

[0019] The extension plate facilitates the installation and connection between the compressor body and the compressor base plate via a vibration damping structure, thereby achieving the vibration damping effect of the vibration damping structure on the compressor body. It also makes it convenient to utilize the space next to the compressor body to install the vibration damping structure.

[0020] Preferably, there are multiple extension plates, which are arranged at intervals along the circumference of the compressor body; the number of vibration damping structures is the same as the number of extension plates, and each vibration damping structure is correspondingly sandwiched between one extension plate and the compressor base plate.

[0021] This configuration allows for vibration reduction through multiple damping structures along various directions of the compressor, thereby further enhancing the vibration reduction effect on the compressor.

[0022] Preferably, the bottom of the vibration damping structure is provided with a first connecting hole, and the compressor mounting base plate is provided with a second connecting hole at the position corresponding to the first connecting hole. The vibration damping structure is fixedly connected to the compressor mounting base plate by fasteners passing through the first connecting hole and the second connecting hole.

[0023] This design ensures a reliable connection between the vibration damping structure and the compressor's fixed base plate during use, thus preventing the vibration damping structure from moving or vibrating relative to the compressor's fixed base plate during compressor operation.

[0024] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model. Attached Figure Description

[0034] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0035] like Figures 1-5As shown, this embodiment of the present invention provides a vibration damping structure 1 for a compressor, which includes a base 11, rollers 12, and a top cover 13. The base 11 is mounted on a compressor mounting plate 3, and an annular support platform 14 is formed on the base 11, extending from the side of the base 11 in a direction away from the base 11. Multiple rollers 12 are disposed on the annular support platform 14 and spaced apart circumferentially along the platform. The cross-sectional shape of each roller 12 is circular in a direction perpendicular to the platform 14. The top cover 13 is located at the top of the base 11 and extends at least partially to the side of the rollers 12 opposite to the annular support platform 14, forming an installation gap between the top cover 13 and the rollers 12 for connecting a compressor extension plate 21.

[0036] Specifically, the annular support platform 14 is disposed on the base 11 and extends in a direction away from the base 11. That is, the annular support platform 14 can form a support surface on its upper surface on the axially outer side of the base 11 for placing the roller 12 structure. On this basis, a plurality of rollers 12 are arranged at intervals along the axial direction of the annular support platform 14 and have a circular cross-sectional shape, thereby enabling rolling relative to the annular support platform 14 at multiple positions along the circumference of the annular support platform 14. For example, the plurality of rollers 12 can be evenly distributed along the circumference of the annular support platform 14.

[0037] Furthermore, the top cover 13 is located on top of the base 11 and forms an installation gap between it and the roller 12 for connecting the compressor extension plate 21, so that the compressor body 2 can be connected and fixed to the vibration damping structure 1 through the compressor extension plate 21 and can contact the roller 12, thereby utilizing the rolling of the roller 12 relative to the annular support platform 14 to achieve a friction effect.

[0038] In practice, the vibration damping structure 1 is first installed on the compressor mounting base 3. Then, the compressor body 2 is connected to the vibration damping structure 1 via an extension plate 21, specifically in the installation gap formed between the upper cover 13 and the roller 12 on the vibration damping structure 1. In this way, the roller 12 is positioned between the compressor body 2 and the base 11 on the compressor mounting base 3. When the compressor body 2 vibrates laterally relative to the compressor mounting base 3, since the roller 12 is positioned between the extension plate 21 connecting the compressor body 2 and the base 11 connecting the compressor mounting base 3, the lateral movement of the extension plate 21 relative to the base 11 can be converted into the rolling movement of the roller 12 between the two. This reduces the lateral movement resistance of the compressor body 2 relative to the compressor mounting base 3, effectively attenuates vibration transmission, and avoids noise generated by direct contact friction between the two.

[0039] In summary, the vibration damping structure 1 for a compressor provided in this embodiment of the present invention connects a base 11 to a compressor mounting plate 3 and forms an annular support platform 14 on the base 11. Multiple circular rollers 12 are arranged axially at intervals on the annular support platform 14. A top cover 13 is provided at the top of the base 11, creating an installation gap between the top cover 13 and the rollers 12 for connecting the compressor extension plate 21. Thus, when the compressor body 2 vibrates laterally relative to the compressor mounting plate 3, the lateral movement of the extension plate 21 relative to the base 11 can be converted into rolling movement of the rollers 12 between the two, effectively attenuating the vibration transmission between the compressor and the compressor mounting plate 3, reducing the lateral amplitude of the compressor. Furthermore, the rollers 12 can convert the lateral movement of the extension plate 21 into rolling movement between the two, avoiding direct contact and friction that would generate noise. Compared to traditional rubber pad vibration damping methods, the vibration damping structure 1 has a longer service life and is more reliable in use.

[0040] It should be noted that, in the embodiments of this utility model, "upper" and "lower" refer to the vertical directions above and below each structure when the compressor fixing base plate 3 is placed on a horizontal plane.

[0041] Since the compressor body 2 needs to be connected to the vibration damping structure 1 via the extension plate 21 after the vibration damping structure 1 is installed on the compressor base plate 3, in some embodiments, the upper cover 13 and the base 11 can be detachably connected.

[0042] This facilitates the connection between the vibration damping structure 1 and the compressor body 2 to achieve the vibration damping function.

[0043] For example, the base 11 may further include a connecting column 111 and a chassis 112, wherein the chassis 112 is used to connect to the compressor mounting base plate 3, the connecting column 111 is disposed above the chassis 112 and extends vertically, and the upper cover 13 is correspondingly connected to the other end of the connecting column 111 away from the chassis 112. Correspondingly, an annular support platform 14 is disposed around the connecting column 111 and located between the chassis 112 and the upper cover 13.

[0044] Based on this, the upper cover 13 and the connecting post 111 are detachably connected. For example, a threaded hole can be opened at the center of the upper cover 13, and an external thread can be provided on a portion of the outer side of the connecting post 111 near its top. This allows the upper cover 13 to be threadedly connected to the connecting post 111. Furthermore, since the threaded connection allows for changing the position of the upper cover 13 relative to the connecting post 111, the connection between the upper cover 13 and the connecting post 111 can be adjusted to allow the upper cover 13 to contact or not contact the compressor extension plate 21. This allows the upper cover 13 to be screwed onto the upper surface of the compressor extension plate 21 when there is a need to fix the compressor, or screwed onto a position higher than the upper surface of the compressor extension plate 21 to ensure vibration damping.

[0045] In some embodiments, to minimize the contact area between the upper cover 13 and the compressor extension plate 21 when they come into contact, thereby reducing the impact of friction, the upper cover 13 may be configured to include a body portion 131 and an abutment portion 132. The body portion 131 is connected to the base 11, and the abutment portion 132 is located on the side of the body portion 131 facing the annular support platform 14 and extends circumferentially along the body portion 131 in an annular shape. Furthermore, in the direction perpendicular to the annular support platform 14, the width of the abutment portion 132 gradually decreases in the direction toward the annular support platform 14.

[0046] In this way, on the one hand, the upper cover 13 and the base can be connected well, and on the other hand, the width of the abutment part 132 gradually decreases in the direction towards the annular support platform 14, so that when the abutment part 132 needs to contact the extension plate 21 of the compressor, the contact surface can be minimized, thereby controlling the friction between the upper cover 13 and the extension plate 21 of the compressor to a small extent.

[0047] In a specific implementation, the cross-sectional shape of the abutment portion 132 along the direction perpendicular to the annular support platform 14 can be an inverted triangle to achieve the effect of the cross-sectional width gradually decreasing along the direction close to the annular support platform 14.

[0048] When the top cover 13 is configured to include a body portion 131 and an abutment portion 132, the threaded hole can be specifically provided on the body portion 131, and the abutment portion 132 is an annular portion extending circumferentially along the bottom of the body portion 131, so as to achieve a uniform abutment effect at all positions circumferentially along the top cover 13. In addition, the body portion 131 and the abutment portion 132 can adopt an integral structure to reduce the number of parts and simplify the structure.

[0049] like Figure 3 and Figure 5As shown, to further ensure minimal friction between the contact portion 132 and the compressor extension plate 21 during contact, in some embodiments, the outline of the bottom surface of the contact portion 132 can be an arc along a direction perpendicular to the annular support platform 14. Furthermore, the inner edge of the bottom surface smoothly connects to the inner surface of the contact portion 132, and the outer edge of the bottom surface smoothly connects to the outer surface of the contact portion 132. This configuration further reduces the area where the contact portion 132 may contact the compressor extension plate 21, thereby further reducing the degree of friction that may occur between the contact portion 132 and the compressor.

[0050] like Figure 4 As shown, in some embodiments, in order to better adapt the roller 12 to the annular support platform 14, the roller 12 can be set as a cylindrical structure, and the central axis of the cylindrical structure is an arc, the curvature of which is the same as the arc of the annular support platform 14.

[0051] This configuration allows the roller 12 to have a larger contact line or contact plane with the annular support platform 14 and the compressor extension plate 21, making the roller 12 more stable when transmitting the movement generated by lateral vibration, thus achieving better vibration reduction and noise reduction effects.

[0052] Of course, in other embodiments, the roller 12 may also be configured as a spherical structure.

[0053] Based on the above, in order to achieve a better fit between the roller 12 and the annular support platform 14, in some embodiments, an arc-shaped support surface 141 can be formed on the upper surface of the annular support platform 14, the roller 12 is located at the position of the arc-shaped support surface 141, and the outer surface of the roller 12 matches the arc-shaped support surface 141 in a direction perpendicular to the annular support platform 14.

[0054] For details, please refer to Figure 5 As shown. This arrangement allows for better cooperation between the roller 12 and the annular support platform 14, enabling the roller 12 to maintain a stable position on the annular support platform 14.

[0055] Based on this, the abutting part 132 of the upper cover 13 can be located directly above the roller 12 in the vertical direction to further improve the fit between the upper cover 13 and the roller 12, thereby ensuring the support and fixing effect of the upper cover 13 and the roller 12 on the extension plate 21 of the compressor.

[0056] In view of the above-mentioned vibration damping structure 1 for compressor, this utility model embodiment also provides a compressor, which includes the above-mentioned vibration damping structure 1.

[0057] like Figure 1 and Figure 2As shown, the compressor includes a compressor body 2 and a compressor base plate 3. The compressor body 2 is mounted on the compressor base plate 3. Furthermore, an extension plate 21 is also provided on the compressor body 2. The extension plate 21 extends from the side of the compressor toward a direction away from the compressor body 2. The vibration damping structure 1 is sandwiched between the extension plate 21 and the compressor base plate 3.

[0058] The extension plate 21 facilitates the installation and connection between the compressor body 2 and the compressor base plate 3 through the vibration damping structure 1 to achieve the vibration damping effect of the vibration damping structure 1 on the compressor body 2. It also facilitates the use of the space next to the compressor body 2 to install the vibration damping structure 1.

[0059] In practice, the extension plate 21 can be extended parallel to the surface of the compressor base plate 3, thereby facilitating the formation of a space between it and the compressor base plate 3 for installing the vibration damping structure 1.

[0060] When connecting the vibration damping structure 1 to the compressor mounting base plate 3, for example, a first connecting hole 113 can be provided at the bottom of the vibration damping structure 1, and a second connecting hole can be provided at the corresponding position of the first connecting hole 113 on the compressor mounting base plate 3. The vibration damping structure 1 is fixedly connected to the compressor mounting base plate 3 by fasteners passing through both the first connecting hole 113 and the second connecting hole. This arrangement ensures that the connection between the vibration damping structure 1 and the compressor mounting base plate 3 is reliable during use, thereby ensuring that the vibration damping structure 1 will not move or vibrate relative to the compressor mounting base plate 3 during compressor operation.

[0061] In one specific implementation, the number of extension plates 21 can be set to multiple, and these multiple extension plates 21 can be arranged at intervals along the circumference of the compressor. Based on this, the number of vibration damping structures 1 is the same as the number of extension plates 21, with each vibration damping structure 1 correspondingly sandwiched between an extension plate 21 and the compressor mounting base plate 3. This arrangement enables vibration damping through multiple vibration damping structures 1 in various directions along the compressor, thereby further improving the vibration damping effect on the compressor.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
