Abstract
Description
Technical Field
[0001] This invention relates to the field of compressor vibration reduction technology, and in particular provides a vibration reduction component and a refrigeration device. Background Technology
[0002] The compressor is the core component of refrigeration equipment and also its main source of vibration. To reduce operating noise, the compressor is typically mounted on the support plate of the refrigeration equipment using vibration damping components. Specifically, these components include damping elements and bolts. The compressor's feet are connected to the damping elements, which are then bolted to the support plate. The compressor's weight acts on the lower part of the damping elements. In the direction from the compressor's feet to the support plate, the vibration generated during compressor operation is absorbed by the lower part of the damping elements, preventing direct transmission to the support plate. However, in the direction from the support plate to the compressor's feet, the higher stiffness of the upper part of the damping elements allows vibrations to easily be transmitted to the bolts, and then from the bolts to the support plate, causing resonance and noise. Therefore, the vibration reduction effect of traditional damping components is still insufficient to meet the actual low-noise application requirements. Summary of the Invention
[0003] The purpose of this invention is to provide a vibration damping component and a refrigeration device, which aims to solve the technical problem that the poor vibration damping effect of existing vibration damping components leads to resonance and noise in the support plate of the refrigeration device.
[0004] To achieve the above objectives, the technical solution adopted in this embodiment of the invention is: a vibration damping component for damping a vibration source mounted on a support. The vibration damping component includes a first damping element and a second damping element. The first damping element includes a first support body and a first buffer body, with the first buffer body connected to the first support body. The second damping element includes a second support body and a second buffer body, with the second buffer body connected to the second support body. The first support body and the second support body are arranged opposite each other, and an installation space for mounting the vibration source is formed between the first support body and the second support body.
[0005] The vibration damping component provided in this embodiment of the invention has at least the following beneficial effects: By setting the installation space for installing the vibration source between the first support and the second support, that is, the connection position between the vibration source and the vibration damping component is located between the first support and the second support, after the vibration source is installed on the support through the vibration damping component, in the direction from the first damping member to the second damping member, the vibration generated by the vibration source when it is working is transmitted through the second support to the second buffer, causing the second buffer to deform under pressure to absorb the vibration. In the direction from the second damping member to the first damping member, the vibration generated by the vibration source when it is working is transmitted through the first support to the first buffer, causing the first buffer to deform under pressure to absorb the vibration. It can be seen that the above-mentioned vibration damping component can absorb vibration in two opposite directions, with a better vibration damping effect, thereby effectively improving the situation of vibration generated by the vibration source being transmitted to the support, avoiding noise generated by resonance of the support, and meeting the requirements of low-noise applications.

[0010] In one embodiment, the outer peripheral wall of the elastic collar is provided with a slot, and the elastic collar and the vibration source can be engaged through the slot.
[0011] In one embodiment, the elastic collar and the first damping member are integrally formed; or, the elastic collar and the second damping member are integrally formed.
[0012] In one embodiment, the first damping member further includes a first pressing part, which is disposed on the end of the first buffer body away from the first support body. The end of the first pressing part away from the first buffer body is provided with a first pressing surface, and the head of the bolt presses against the first pressing surface.
[0013] In one embodiment, the thickness of the first pressing part is greater than or equal to the maximum deformation stroke of the first buffer body.
[0014] In one embodiment, the first buffer body has a first stiffness adjustment hole.
[0015] In one embodiment, the number of the first stiffness adjustment holes is multiple, and the multiple first stiffness adjustment holes are evenly distributed along the circumference of the first buffer body.
[0016] In one embodiment, the second buffer body is provided with a second stiffness adjustment hole.
[0017] In one embodiment, the number of the second stiffness adjustment holes is multiple, and the multiple second stiffness adjustment holes are evenly distributed along the circumference of the second buffer body.
[0018] In one embodiment, the second damping member further includes a second pressing part, which is disposed on the end of the second buffer body away from the second support body. The end of the second pressing part away from the second buffer body is provided with a second pressing surface, which is used to press against the support.
[0019] In one embodiment, the thickness of the second pressing part is greater than or equal to the maximum deformation stroke of the second buffer body.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0036] A first aspect of the present invention provides a vibration damping component 110, which can be used to mount a vibration source in an electrical device onto a support to absorb the vibration generated by the vibration source. For example, the electrical device is a refrigeration device 100, the vibration source is a compressor in the refrigeration device 100, and the support is a support plate 130 in the refrigeration device 100. The compressor generates vibration when it is working. The compressor is mounted on the support plate 130 through the vibration damping component 110. The vibration damping component 110 can absorb the vibration generated when the compressor is working, effectively preventing the vibration generated when the compressor is working from being transmitted to the support plate 130, thereby effectively reducing the operating noise of the refrigeration device 100.
[0037] The following describes the vibration damping component 110 in detail, taking its application in a refrigeration device 100 as an example, with reference to the accompanying drawings.
[0038] Please combine Figures 1 to 4 As shown, the vibration damping assembly 110 includes a first vibration damping member 111 and a second vibration damping member 112. The first vibration damping member 111 includes a first support body 1111 and a first buffer body 1112. The first buffer body 1112 is connected to the first support body 1111. The second vibration damping member 112 includes a second support body 1121 and a second buffer body 1122. The second buffer body 1122 is connected to the second support body 1121. The first support body 1111 and the second support body 1121 are arranged opposite each other, and an installation space 116 is formed between the first support body 1111 and the second support body 1121. The compressor foot 120 is installed in the installation space 116, that is, the compressor foot 120 is connected between the first support body 1111 and the second support body 1121.
[0039] It should be noted that the first damping element 111 and the second damping element 112 are made of elastic materials, including but not limited to rubber and silicone.
[0040] Specifically, the first damping member 111 and the second damping member 112 are distributed longitudinally. The first damping member 111 is disposed on the side of the compressor foot 120 away from the support plate 130, and the second damping member 112 is disposed between the compressor foot 120 and the support plate 130. The longitudinal stiffness of the first support body 1111 is greater than that of the first buffer body 1112. Similarly, the longitudinal stiffness of the second support body 1121 is greater than that of the second buffer body 1122. That is, in the vibration damping assembly 110, the first buffer body 1112 and the second buffer body 1122 mainly play the role of absorbing vibration, while the first support body 1111 and the second support body 1121 cooperate with each other to clamp the compressor foot 120. The vibration generated when the compressor is working is transmitted to the first buffer body 1112 and the second buffer body 1122 through the first support body 1111 and the second support body 1121.
[0041] It should be noted that the longitudinal stiffness of the first buffer body 1112 and the second buffer body 1122 can be determined according to the weight of the compressor. When the compressor is heavy, the longitudinal stiffness of the first buffer body 1112 and the second buffer body 1122 can be appropriately increased. Conversely, when the compressor is light, the longitudinal stiffness of the first buffer body 1112 and the second buffer body 1122 can be appropriately decreased. Specifically, the longitudinal stiffness of the first buffer body 1112 can be adjusted by changing its thickness, outer diameter, material, and other factors. Similarly, the longitudinal stiffness of the second buffer body 1122 can be adjusted by changing its thickness, outer diameter, material, and other factors.
[0042] An installation space 116 is formed between the first support 1111 and the second support 1121. The compressor foot 120 is installed in the installation space 116. That is, the connection position between the compressor foot 120 and the vibration damping assembly 110 is located between the first support 1111 and the second support 1121. After the compressor is installed on the support plate 130 through the vibration damping assembly 110, the vibration generated by the compressor during operation is transmitted through the second support 1121 to the second buffer 1122 in the direction from the first vibration damper 111 to the second vibration damper 112, so that the second buffer 1122 deforms under pressure to absorb the vibration. In the direction from the second vibration damper 112 to the first vibration damper 111, the vibration generated by the compressor during operation is transmitted through the first support 1111 to the first buffer 1112, so that the first buffer 1112 deforms under pressure to absorb the vibration. As can be seen, the vibration damping component 110 can absorb vibration in two directions, and the vibration damping effect is good. This can effectively improve the situation where the vibration generated by the compressor during operation is transmitted to the support plate 130, avoid the resonance of the support and generate noise, effectively reduce the operating noise of the refrigeration equipment 100, and meet the requirements of low noise application.
[0043] In one embodiment, please combine Figures 1 to 4 As shown, the vibration damping assembly 110 also includes bolts 113. A first through hole 1114 is formed in the first damping member 111, penetrating the first support body 1111 and the first buffer body 1112. A second through hole 1124 is formed in the second damping member 112, penetrating the second support body 1121 and the second buffer body 1122. The first through hole 1114 and the second through hole 1124 are connected to form an installation channel 117. The bolts 113 can pass through the installation channel 117 and connect to the support plate 130. It can be understood that when the compressor's foot 120 is installed in the installation space 116, the bolts 113 penetrate the foot 120 to fix the compressor to the support plate 130 via the vibration damping assembly 110.
[0044] Understandably, the outer diameter of the head of bolt 113 is larger than the diameter of the first through hole 1114. When bolt 113 is connected to support plate 130, the head of bolt 113 presses against the side of the first damper 111 away from the second damper 112, or there is a certain gap between the head of bolt 113 and the side of the first damper 111 away from the second damper 112. In this embodiment, when bolt 113 is connected to support plate 130, the head of bolt 113 presses against the side of the first damper 111 away from the second damper 112, and the side of the second damper 112 away from the first damper 111 presses against support plate 130. This can effectively restrict the position of the first damper 111 and the second damper 112, thereby enabling the first damper 111 and the second damper 112 to effectively absorb vibration.
[0045] Specifically, the support plate 130 has a screw hole, and the bolt 113 passes through the mounting channel 117 and is threaded into the screw hole. Alternatively, the support plate 130 has a through hole, and the vibration damping assembly 110 also includes a nut (not shown in the figure), and the bolt 113 passes through the mounting channel 117 and the through hole in sequence and is threaded into the nut.
[0046] In one embodiment, please combine Figure 2 and Figure 4 As shown, the vibration damping assembly 110 also includes a sleeve 114, which is disposed within the mounting channel 117, and the bolt 113 passes through the sleeve 114. By providing the sleeve 114 within the mounting channel 117, the inner wall of the mounting channel 117 can be separated from the outer wall of the bolt 113, that is, the inner wall of the first through hole 1114 can be separated from the outer wall of the bolt 113, and the inner wall of the second through hole 1124 can be separated from the outer wall of the bolt 113. This effectively prevents mutual friction between the first damping member 111 and the bolt 113, and between the second damping member 112 and the bolt 113, thus preventing wear on the first damping member 111 and the second damping member 112.
[0047] Specifically, the outer wall of the sleeve 114 is clearance-fitted with the inner wall of the mounting channel 117, or the outer peripheral wall of the bolt 113 is clearance-fitted with the inner peripheral wall of the sleeve 114, or both the outer wall of the sleeve 114 and the inner wall of the mounting channel 117 are clearance-fitted. Thus, there is at least a certain gap between the inner wall of the mounting channel 117 and the outer wall of the bolt 113, which prevents the vibration generated during compressor operation from being transmitted horizontally to the bolt 113 after reaching the first damping member 111 or the second damping member 112, thereby further improving the vibration damping effect of the damping assembly 110.
[0048] In one embodiment, please combine Figures 2 to 4As shown, the vibration damping assembly 110 also includes an elastic collar 115, which is sleeved on the outer periphery of the bolt 113 and can be connected to the vibration source. It is understood that the elastic collar 115 is made of an elastic material, including but not limited to rubber and silicone. Specifically, a connection hole is provided on the compressor foot 120, and the elastic collar 115 is disposed within the connection hole. Thus, the elastic collar 115 can effectively separate the compressor foot 120 from the bolt 113, and can absorb the vibration generated during compressor operation, preventing the vibration from being transmitted to the bolt 113, further improving the vibration damping effect of the vibration damping assembly 110.
[0049] In the above embodiment, when the sleeve 114 is provided in the installation channel 117, the elastic collar 115 is sleeved outside the sleeve 114, that is, the elastic collar 115 is provided in the connection hole of the foot 120, the sleeve 114 passes through the inner ring hole of the elastic collar 115, and the bolt 113 passes through the sleeve 114.
[0050] Specifically, please combine Figure 5 As shown, the outer peripheral wall of the elastic collar 115 is provided with a groove 1151. The elastic collar 115 is engaged in the connection hole through the groove 1151 to realize the connection between the elastic collar 115 and the machine foot 120.
[0051] In the above embodiments, in order to simplify the production process of the vibration damping component 110 and reduce the production cost of the vibration damping component 110, the elastic collar 115 and the first vibration damping component 111 are integrally formed, or the elastic collar 115 and the second vibration damping component 112 are integrally formed.
[0052] Of course, in other embodiments, the elastic collar 115 can also be molded separately.
[0053] In one embodiment, please combine Figure 4 As shown, the first damping member 111 also includes a first pressing part 1113, which is disposed on the end of the first buffer body 1112 away from the first support body 1111. The end of the first pressing part 1113 away from the first buffer body 1112 is provided with a first pressing surface 11131, and the head of the bolt 113 presses against the first pressing surface 11131. The vibration generated when the compressor is working is transmitted to the first buffer body 1112 through the first support body 1111, and then to the first pressing part 1113 through the first buffer body 1112. Since the head of the bolt 113 presses against the first pressing surface 11131, the first pressing part 1113 reacts to the first buffer body 1112, causing the first buffer body 1112 to be deformed under pressure, thereby absorbing the vibration.
[0054] Understandably, the first through hole 1114 passes through the first pressing part 1113, the first buffer body 1112 and the first support body 1111, so that the bolt 113 can pass through the entire first damping member 111.
[0055] In the above embodiment, the thickness of the first pressing part 1113 is greater than or equal to the maximum deformation stroke of the first buffer body 1112. This allows the deformation stroke of the first buffer body 1112 to be utilized to the maximum extent, so that the first buffer body 1112 can absorb vibration more fully, thereby further improving the vibration reduction effect of the vibration damping component 110.
[0056] In one embodiment, please combine Figure 6 As shown, a first stiffness adjustment hole 11121 is provided on the first buffer body 1112. By providing the first stiffness adjustment hole 11121 on the first buffer body 1112, the number of the first stiffness adjustment holes 11121 can be determined according to the weight of the compressor. In this way, the stiffness of the first buffer body 1112 can be effectively adjusted so that the stiffness of the first buffer body 1112 can match the weight of the compressor. This allows the vibration damping component 110 to achieve a near-zero stiffness state in practical applications, effectively absorbing low-frequency vibrations.
[0057] In the above embodiments, please refer to Figure 6 As shown, there are multiple first stiffness adjustment holes 11121, which are evenly distributed around the circumference of the first buffer body 1112. This makes the overall stiffness of the first buffer body 1112 more uniform, thereby enabling the first buffer body 1112 to better absorb vibration and further improve the vibration reduction effect of the vibration damping component 110.
[0058] It should be noted that the circumferential direction mentioned above refers to the direction surrounding bolt 113.
[0059] In one embodiment, please combine Figure 6 As shown, a second stiffness adjustment hole 11221 is provided on the second buffer body 1122. By providing the second stiffness adjustment hole 11221 on the second buffer body 1122, the number of the second stiffness adjustment holes 11221 can be determined according to the weight of the compressor. In this way, the stiffness of the second buffer body 1122 can be effectively adjusted so that the stiffness of the second buffer body 1122 can match the weight of the compressor. This allows the vibration damping component 110 to achieve a near-zero stiffness state in practical applications, effectively absorbing low-frequency vibrations.
[0060] In the above embodiments, please refer to Figure 6As shown, there are multiple second stiffness adjustment holes 11221, which are evenly distributed along the circumference of the second buffer body 1122. This makes the overall stiffness of the second buffer body 1122 more uniform, thereby enabling the second buffer body 1122 to better absorb vibration and further improve the vibration reduction effect of the vibration damping component 110.
[0061] It should be noted that the circumferential direction mentioned above refers to the direction surrounding bolt 113.
[0062] In one embodiment, please combine Figure 4 As shown, the second damping member 112 also includes a second pressing part 1123, which is disposed on the end of the second buffer body 1122 away from the second support body 1121. The end of the second pressing part 1123 away from the second buffer body 1122 has a second pressing surface 11231, which is used to press against the support. The vibration generated when the compressor is working is transmitted to the second buffer body 1122 through the second support body 1121, and then to the second pressing part 1123 through the second buffer body 1122. The second pressing surface 11231 presses against the support plate 130, so that the second pressing part 1123 reacts to the second buffer body 1122, causing the second buffer body 1122 to be deformed under pressure, thereby absorbing the vibration.
[0063] Understandably, the second through hole 1124 passes through the second pressing part 1123, the second buffer body 1122 and the second support body 1121 so that the bolt 113 can pass through the entire second damping member 112.
[0064] In the above embodiment, the thickness of the second pressing part 1123 is greater than or equal to the maximum deformation stroke of the second buffer body 1122. This allows the deformation stroke of the second buffer body 1122 to be utilized to the maximum extent, so that the second buffer body 1122 can absorb vibration more fully, thereby further improving the vibration reduction effect of the vibration damping component 110.
[0065] In one embodiment, please combine Figure 4As shown, the first support 1111 has a hollow cylindrical structure, and the first buffer 1112 has a hollow frustum structure. The frustum structure includes, but is not limited to, a frustum of a cone or a frustum of a triangular prism. The outer periphery of the first buffer 1112 is connected to the cylindrical wall of the first support 1111. Specifically, the bottom outer periphery of the first buffer 1112 is connected to the cylindrical wall of the first support 1111, and the top of the first buffer 1112 is connected to the first pressing part 1113. Alternatively, the top outer periphery of the first buffer 1112 is connected to the cylindrical wall of the first support 1111, and the bottom of the first buffer 1112 is connected to the first pressing part 1113. It should be noted that the bottom of the first buffer 1112 refers to the end with a larger outer diameter, and the top of the first buffer 1112 refers to the end with a smaller outer diameter.
[0066] Of course, the first buffer body 1112 can also be a flat plate structure, with the outer periphery of the first buffer body 1112 connected to the cylindrical wall of the first support body 1111.
[0067] In one embodiment, please combine Figure 4 As shown, the second support 1121 has a hollow cylindrical structure, and the second buffer 1122 has a hollow frustum structure. The frustum structure includes, but is not limited to, a frustum of a cone or a frustum of a triangle. The outer periphery of the second buffer 1122 is connected to the cylindrical wall of the second support 1121. Specifically, the bottom outer periphery of the second buffer 1122 is connected to the cylindrical wall of the second support 1121, and the top of the second buffer 1122 is connected to the second pressing part 1123. Alternatively, the top outer periphery of the second buffer 1122 is connected to the cylindrical wall of the second support 1121, and the bottom of the second buffer 1122 is connected to the second pressing part 1123. It should be noted that the bottom of the second buffer 1122 refers to the end with a larger outer diameter, and the top of the second buffer 1122 refers to the end with a smaller outer diameter.
[0068] Of course, the second buffer body 1122 can also be a flat plate structure, with the outer periphery of the second buffer body 1122 connected to the cylindrical wall of the second support body 1121.
[0069] The working principle of the vibration damping assembly 110 will be explained below using an embodiment in which the first vibration damping member 111 is disposed on the side of the compressor foot 120 away from the support plate 130 and the second vibration damping member 112 is disposed between the compressor foot 120 and the support plate 130 as an example.
[0070] When the compressor is mounted on the support plate 130 via the vibration damping assembly 110, the weight of the compressor is applied to the second vibration damper 112, causing the second buffer body 1122 to deform under pressure to the equilibrium working position. At this time, the overall stiffness of the vibration damping assembly 110 is in a near-zero stiffness state. When the compressor is working, in the direction from the first vibration damper 111 to the second vibration damper 112, the vibration generated by the compressor during operation is transmitted through the second support body 1121 to the second buffer body 1122, causing the second buffer body 1122 to continue to deform under pressure to absorb the vibration. Meanwhile, in the direction from the second vibration damper 112 to the first vibration damper... In the direction of component 111, the vibration generated by the compressor during operation is transmitted to the first buffer body 1112 through the first support body 1111, causing the first buffer body 1112 to deform under pressure to absorb the vibration. This avoids the vibration being transmitted to the support plate 130, resulting in a better vibration reduction effect. This effectively reduces the operating noise of the refrigeration equipment 100. At the same time, since the overall stiffness of the vibration damping component 110 can reach a near-zero stiffness state, the lower limit of the vibration isolation frequency of the vibration damping component 110 can be lowered, thus widening the vibration isolation frequency range of the vibration damping component 110 and further improving the effect of the vibration damping component 110.
[0071] A second aspect of the present invention provides a refrigeration device 100, please refer to... Figure 1 As shown, the refrigeration equipment 100 includes a compressor, a support plate 130, and a vibration damping component 110 of any one or more of the above embodiments. The compressor includes a body and a foot 120. The foot 120 is connected to the body and is installed in the installation space 116 of the vibration damping component 110. The vibration damping component 110 is installed on the support plate 130.
[0072] It should be noted that refrigeration equipment 100 includes, but is not limited to, refrigerators and air conditioners.
[0073] Since the refrigeration equipment 100 adopts the vibration damping component 110 of any of the above embodiments, the vibration generated when the compressor is working can be effectively absorbed by the vibration damping component 110, thereby effectively reducing the working noise of the refrigeration equipment 100.
[0074] In one embodiment, each foot 120 is connected to the support plate 130 via multiple vibration damping components 110. The number of vibration damping components 110 can be determined according to the weight of the compressor, which can more effectively absorb the vibration generated when the compressor is working, thereby further reducing the operating noise of the refrigeration equipment 100.
[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
