Description

Technical Field

[0001] This invention relates to the field of compressor vibration reduction and noise reduction technology, and more specifically, to a limiting vibration reduction device and an air conditioner having the same. Background Technology

[0002] During operation, compressors generate vibrations related to their working principle, which are transmitted to the piping system connected to the compressor. Therefore, solving the vibration and noise problem caused by compressor operation is a major challenge.

[0003] Taking the compressor of a vehicle air conditioner as an example, the operating vibration of the compressor itself and environmental vibration pose a significant challenge to the attached piping system, especially with the compressor being placed vertically, which exacerbates this risk. Existing technologies typically address compressor vibration and noise by damping the bottom of the compressor and fixing it to the compressor body. For example, existing technologies disclose a buffer structure for the compressor bottom, including springs and rubber buffer structures, to achieve vibration damping. However, the compressor's overall center of gravity is relatively high, and with the added vibration from the compressor itself and the vehicle environment, the relative displacement of the attached piping system is significant, increasing the risk of pipe breakage. Existing technologies also disclose a compressor vibration damping structure that uses clamps and buffer pads to achieve vibration damping. Using clamps to rigidly connect the compressor body to the outer panel effectively reduces the amplitude of piping system vibration caused by compressor vibration, but the vibration and noise issues resulting from the connection to the outer panel significantly reduce the reliability and comfort of the vehicle air conditioner.

[0004] There is currently no effective solution to the vibration and noise problems caused by the complex excitation characteristics of compressors and the use of clamps to rigidly connect compressor equipment. Summary of the Invention

[0052] Combination Figures 1 to 12 As shown, according to a specific embodiment of this application, a limiting vibration damping device is provided.

[0053] The limiting vibration damping device includes a first damping component 11, a housing 13, and a second damping component 12. The first damping component 11 is connected to the compressor and is used to dampen vibration and reduce noise in a first preset direction of the compressor. One side of the housing 13 is connected to the mounting base, and the other side of the housing 13 is detachably connected to the first damping component 11. The housing 13 has a working cavity 130, and at least a portion of the first damping component 11 extends into the working cavity 130. The second damping component 12 is disposed in the working cavity 130 and is detachably connected to the housing 13. The second damping component 12 is connected to a portion of the first damping component 11 and is used to dampen vibration and reduce noise in a second preset direction of the compressor.

[0054] Applying the technical solution of this embodiment, the first vibration damping component 11 is connected to the compressor, and the housing 13 is connected to the mounting base. The first vibration damping component 11 is used to achieve vibration reduction and noise reduction in the first preset direction of the compressor, and the second vibration damping component 12 is used to achieve vibration reduction and noise reduction in the second preset direction of the compressor. The compressor vibration is transmitted to the limiting vibration damping device, and after the vibration is reduced, it is transmitted to the mounting base. When applied to air conditioning equipment, it can effectively reduce the vibration noise generated by the compressor rigidly connected to the outer panel of the air conditioner through the clamp, and increase the reliability and comfort of the air conditioning equipment.

[0055] Specifically, the first damping component 11 includes a connecting rod assembly, a first elastic element 114, and a first connecting member 115. The connecting rod assembly is detachably connected to the housing 13. The connecting rod assembly includes a connecting rod 1112, which extends along a first preset direction. The first end of the first elastic element 114 abuts against a portion of the connecting rod assembly, and the first elastic element 114 is sleeved on the connecting rod 1112. The first connecting member 115 has a first mounting hole 1150, through which it is sleeved on the connecting rod 1112, and the first connecting member 115 abuts against the second end of the first elastic element 114. By providing the first elastic element 114, the elastic deformation of the first elastic element 114 dissipates the vibration energy of the compressor in the first preset direction, effectively reducing noise and achieving the vibration damping function.

[0056] In one exemplary embodiment of this application, the first preset direction is horizontal, the second preset direction is vertical, the first elastic element 114 is a high-stiffness helical spring, and the first connecting element 115 is a connecting block. Preferably, the first mounting hole 1150 of the connecting block is provided with a threaded structure so that the connection between the connecting block and the connecting rod 1112 is more stable.

[0057] Specifically, the linkage assembly includes a connecting rod 111 and a cover plate 113. The connecting rod 111 includes a base plate 1111 and a connecting rod 1112, and the base plate 1111 is connected to the compressor. The cover plate 113 has a second mounting hole 1132, and the cover plate 113 is connected to the connecting rod 1112 through the second mounting hole 1132. The cover plate 113 is detachably connected to the housing 13. By setting the cover plate 113 to achieve a detachable connection with the housing 13, it is easier to inspect and replace the first shock absorber assembly 11. When the connection of the parts is incorrect, the cover plate 113 can be removed separately for inspection and replacement.

[0058] In one exemplary embodiment of this application, the substrate 1111 is square, one end face of the substrate 1111 is connected to the compressor, and the other end face of the substrate 1111 is connected to the connecting rod 1112. Preferably, the substrate 1111 and the connecting rod 1112 are integrally formed.

[0059] The cover plate 113 includes a cover plate body 1131 and a fixing plate 1133. The cover plate body 1131 has a second mounting hole 1132. Multiple fixing plates 1133 are arranged circumferentially along the cover plate body 1131 and are connected to the cover plate body 1131 at an angle. Multiple fixing holes 1134 are provided on the fixing plates 1133, and the cover plate 113 is detachably connected to the housing 13 through the fixing holes 1134. By providing multiple fixing plates 1133, the cover plate 113 can be connected and fixed to the housing 13 from multiple directions, making the connection more secure. By providing multiple fixing holes 1134, the cover plate 113 can have multiple fixed positions, thereby adjusting the position of the cover plate 113 in a first preset direction.

[0060] In one exemplary embodiment of this application, to facilitate adjustment of the position of the cover plate 113 in a first preset direction (i.e., horizontal direction), a plurality of first positioning holes 132 are provided on the housing 13. After the cover plate 113 is adjusted to the preset position, the housing 13 and the cover plate 113 are connected and fixed by bolts. Preferably, in this embodiment, to facilitate the sliding of the cover plate 113 within the housing 13, a sliding groove structure is also provided on the housing 13. The sliding groove structure of the housing 13 allows the protrusion of the cover plate 113 of the first shock-absorbing assembly 11 to move, thereby adjusting the installation position of the cover plate 113.

[0061] Furthermore, the first damping assembly 11 also includes a buffer member 112, which has a third mounting hole 1120. The buffer member 112 is sleeved on the connecting rod 1112 through the third mounting hole 1120, and is disposed between the base plate 1111 and the cover plate 113. The buffer member 112 can reduce the vibration of the compressor in the first preset direction, thereby reducing vibration noise.

[0062] Specifically, the buffer 112 includes a buffer body 1121, on which a boss structure 1122 is provided. At least a portion of the boss structure 1122 is located within the second mounting hole 1132, and a third mounting hole 1120 is provided on the boss structure 1122. By providing the boss structure 1122, the displacement of the compressor in the radial direction (i.e., the vertical direction, opposite to the aforementioned horizontal direction) of the second mounting hole 1132 can be limited.

[0063] In conjunction with the foregoing embodiments, the buffer 112, in cooperation with the aforementioned first elastic member 114, can achieve both horizontal limiting and vibration damping of the compressor and vertical limiting of the compressor. The maximum deformation of the buffer 112 and the first elastic member 114 in the first preset direction is the maximum displacement of the compressor in the horizontal direction, and the maximum deformation of the boss structure 1122 in the vertical plane within the second mounting hole 1132 is the maximum displacement in the vertical direction. The buffer 112 and the first elastic member 114 simultaneously provide vibration damping and limiting functions, effectively avoiding compressor vibration and displacement problems that may occur when damping the compressor.

[0064] Preferably, the buffer 112 is made of rubber. Rubber has good elasticity and noise absorption capabilities, and using rubber can achieve better vibration reduction.

[0065] In one exemplary embodiment of this application, the buffer body 1121 is square, and the buffer body 1121 is a rubber block of uniform thickness. The boss structure 1122 is a frustum. The initial deformation of the buffer member 112 and the first elastic member 114 is 0. To improve the vibration reduction effect, the buffer body 1121, the cover plate body 1131, and the base plate 1111 abut against each other and fit tightly. The contact surfaces of the abutment are all rough surfaces.

[0066] Furthermore, the second damping assembly 12 includes a fixing member 121 and a second elastic member 122. Multiple fixing members 121 are distributed circumferentially along the working cavity 130 and are fixedly connected to the housing 13. Multiple second elastic members 122 are disposed between two fixing members 121, forming a limiting space 1220 to accommodate at least a portion of the first connecting member 115. By providing the second elastic member 122, when the vibration of the compressor is transmitted to the first connecting member 115, the first connecting member 115 compresses the second elastic member 122, causing the second elastic member 122 to undergo elastic deformation, absorbing vibration energy, reducing vibration, and thus reducing vibration noise.

[0067] In an exemplary embodiment of this application, the fixing member 121 is a fixing block. To achieve a fixed connection between the fixing member 121 and the housing 13, an outer fixing hole 1211 and an inner fixing hole 1212 are provided on the fixing member 121, and a fourth mounting hole 1221 is provided on the second elastic member 122. Preferably, the outer fixing hole 1211 is provided on the end face of the fixing member 121 corresponding to the end face of the housing 13, and the inner fixing hole 1212 is provided on the end face of the fixing member 121 corresponding to the end face of the second elastic member 122. It should be noted that, in this embodiment, since the fixing member 121 is connected to both surfaces of the housing 13 simultaneously, corresponding outer fixing holes 1211 are provided on both end faces of the fixing member 121. Preferably, two outer fixing holes 1211 are provided on each end face to make the connection more stable. The number of inner fixing holes 1212 is set according to the number of second elastic members 122 connected to the fixing member 121. For example, in Figure 3 In this embodiment, each fixing member 121 connects to two second elastic members 122, and an inner fixing hole 1212 is formed on the corresponding end face. It should be understood that the position and number of the outer fixing holes 1211 and inner fixing holes 1212 on the corresponding end faces can be adjusted according to actual needs. In this embodiment, the connection method is bolt connection.

[0068] To facilitate the fixed connection between the fastener 121 and the housing 13, in this embodiment, a second positioning hole 133 is also provided on the housing 13, and the outer fixing hole 1211 of the fastener 121 and the second positioning hole 133 of the housing 13 are connected by a bolt assembly 14.

[0069] like Figure 11 As shown, in conjunction with the aforementioned embodiments, the position of the cover plate 113 in the horizontal direction is adjustable. By adjusting the position of the cover plate 113 in the horizontal direction, the distance B between the second elastic element 122 and the cover plate 113 is adjusted, thereby adjusting the balance range of the excitation force of the second elastic element 122 on the compressor in the vertical plane, increasing the applicability of the limiting vibration damping device of this embodiment to the compressor, and adapting to various compressor types and operating conditions.

[0070] Furthermore, the second shock absorber assembly 12 also includes a third elastic element 124. There are multiple third elastic elements 124. The first end of the third elastic element 124 is connected to the second elastic element 122. The third elastic element 124 extends in a direction away from the limiting space 1220. The second end of the third elastic element 124 abuts against the housing 13.

[0071] In conjunction with the foregoing embodiments, by providing a third elastic element 124, when the compressor's vibration is transmitted to the first connecting member 115, the first connecting member 115 compresses the second elastic element 122, which in turn compresses the third elastic element 124. The third elastic element 124 and the second elastic element 122 simultaneously undergo elastic deformation, absorbing vibration energy, reducing vibration, and further reducing vibration noise. Preferably, the third elastic element 124 is a low-stiffness helical spring.

[0072] Furthermore, the second damping assembly 12 also includes a second connector 123, which is correspondingly disposed with the second elastic member 122. The second connector 123 has a connecting hole 1231, through which the second connector 123 and the second elastic member 122 are connected. The second connector 123 has at least one connecting position 1232 for connecting the third elastic member 124. The provision of the second connector 123 makes the connection between the second elastic member 122 and the third elastic member 124 more secure and facilitates subsequent replacement.

[0073] In one exemplary embodiment of this application, the connection 1232 is a cylinder, and the second connector 123 also has a groove 1233 for accommodating at least a portion of the second elastic member 122.

[0074] Specifically, the second elastic element 122 is an arc-shaped spring plate, with both ends connected to the fixing element 121. The highest point of the arc-shaped spring plate protrudes towards the geometric center of the limiting space 1220. This arrangement ensures that when the first connecting element 115 is located in the limiting space 1220, multiple surfaces of the first connecting element 115 abut against the highest point of the arc-shaped spring plate. When vibration is transmitted from the compressor to the first connecting element 115, the vibration can be transmitted from the highest point of the arc-shaped spring plate to both ends, resulting in a significant vibration reduction effect.

[0075] Furthermore, a second connecting member 123 is provided at the highest point of the arc-shaped spring plate. This allows the vibration to be transmitted simultaneously along the third elastic member 124 and the arc-shaped spring plate, which are connected to the second connecting member 123, when the vibration is transmitted from the compressor to the first connecting member 115. The simultaneous action of the third elastic member 124 and the arc-shaped spring plate can improve the vibration reduction efficiency and enhance the vibration reduction effect.

[0076] In conjunction with the foregoing embodiments, preferably, the groove 1233 of the second connector 123 abuts against the highest point of the arc-shaped spring plate, and a fifth mounting hole 1222 is opened at the highest point of the arc-shaped spring plate. The second connector 123 and the arc-shaped spring plate are bolted together through the connecting hole 1231 and the fifth mounting hole 1222.

[0077] Furthermore, there are four fasteners 121. This arrangement makes the connection between the second damping assembly 12 and the housing 13 more stable.

[0078] In one exemplary embodiment of this application, there are four fasteners 121, and a second elastic member 122 is provided between adjacent fasteners 121. Each second elastic member 122 is connected to a second connector 123, and each second connector 123 is connected to two third elastic members 124.

[0079] Specifically, the housing 13 includes a limiting member 131, which is disposed on the inner wall of the housing 13. There are multiple limiting members 131, which are used to accommodate at least a portion of the third elastic member 124.

[0080] In one exemplary embodiment of this application, when the limiting member 131 is a limiting post and the third elastic member 124 is a helical spring, one end of the helical spring abuts against the inner wall of the housing 13 and the other end abuts against the outer surface of the connecting position 1232, and the helical surface of the helical spring is in clearance fit with the inner surface of the limiting post.

[0081] Preferably, the outer periphery of the limiting post is provided with reinforcing ribs to increase structural strength, the interior of the limiting post is used to place a helical spring, and the side wall of the limiting post has an opening structure to allow the second connecting member 123 to slide in the horizontal plane.

[0082] In conjunction with the above embodiments, this application also provides a preferred embodiment of the limiting vibration damping device. In this embodiment, the length W of the curved portion of the arc-shaped spring plate is 45%-50% of the length L of the limiting vibration damping device, and the width V of the curved portion of the arc-shaped spring plate is set to 30%-40% of the length W of the curved portion of the arc-shaped spring plate. The length L of the limiting vibration damping device is 30%-35% of the compressor cylinder diameter. The actual size of the limiting vibration damping device can adapt to compressor equipment of different specifications. The height H of the limiting vibration damping device is equal to the length L of the limiting vibration damping device, and the overall structure is square, but this appearance is not limited; it can also be a cylinder, prism, etc. To avoid noise generation when the first damping component 11 collides with the housing 13 during operation, the vertical distance between the base plate 1111 and the inner surface of the housing 13, and the vertical distance between the buffer 112 and the inner surface of the housing 13, are both not less than 15%L. Figure 11 The figure shows the vertical distance between the base plate 1111 and the buffer 112 and the inner surface of the housing 13 when the base plate 1111 and the buffer 112 are at the same height. To enhance the vibration reduction effect and better utilize the vibration reduction function of the limiting vibration reduction device in any direction, the second vibration damping component 12 has an axisymmetric structure. Preferably, the bolt assembly 14 is a sheet metal bolt, and both ends of the bolt assembly 14 are connected to the outside through bolts and nuts, which has the characteristics of low cost and easy disassembly and assembly.

[0083] According to another specific embodiment of this application, an air conditioner is provided, which has a limiting vibration damping device, the limiting vibration damping device being the aforementioned limiting vibration damping device.

[0084] Specifically, the air conditioner includes a compressor unit 2 and a mounting plate. The compressor unit 2 is provided with a compressor clamp 3. The base plate 1111 of the first shock-absorbing component 11 of the limiting and damping device is connected to the compressor clamp 3. The side of the housing 13 of the limiting and damping device away from the first shock-absorbing component 11 is connected to the mounting plate.

[0085] In this embodiment, for compressor excitation, the limiting vibration damping device, through the limiting function of the cover plate 113, can exert the damping effect of the buffer member 112, the third elastic member 124, the second elastic member 122, and the first elastic member 114 in any direction. The vibration of the compressor device 2 is transmitted to the limiting vibration damping device through the compressor clamp 3. After the vibration is reduced by the limiting vibration damping device, it is transmitted to the mounting plate, effectively avoiding the vibration and noise problem caused by the rigid connection between the compressor and the mounting plate through the clamp in the prior art, thus enhancing the reliability and comfort of the air conditioner.

[0086] It should be noted that the air conditioner in this embodiment can be a vehicle air conditioner, a marine air conditioner, and is backward compatible with more air conditioner devices used in non-severe conditions.

[0087] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0088] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this invention.

[0089] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0090] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
