[0037] Refrigerators typically have shelves for storing items. To accommodate items of different sizes, these shelves are usually designed with motorized lifting mechanisms, driven by a motor. During this movement, the motor generates vibrations. Because the motor is connected to the refrigerator casing, these vibrations are inevitably transmitted to the casing. This transmission causes the casing to vibrate, resulting in significant noise. In some technologies, a shock-absorbing sleeve is installed between the motor mounting bracket and the refrigerator casing to buffer and absorb the vibrations transmitted from the motor, thereby reducing the vibration energy transmitted to the casing and achieving noise reduction. However, while this reduces vibration to some extent, a considerable amount still passes through the shock-absorbing sleeve to the refrigerator casing, resulting in relatively high noise levels during shelf movement.

[0038] The vibration damping component of this embodiment improves the vibration damping effect by providing vibration damping holes 105 in the vibration damping body 100, thereby reducing the transmission of vibration between the motor and the housing. See below for further details. Figures 1 to 6 The shock-absorbing components of this utility model embodiment are further described below.

[0039] Reference Figures 1 to 6 As shown, the first aspect of this utility model provides a shock-absorbing component applied to a storage cabinet. The storage cabinet includes, but is not limited to, a refrigerator, a freezer, and a cabinet for placing objects. The shock-absorbing component of this utility model is applied to a refrigerator and connected between the mounting bracket 300 and the shelf inside the refrigerator.

[0040] Specifically, the damping assembly includes a damping body 100. The material of the damping body 100 includes, but is not limited to, rubber, polyurethane, etc. The damping body 100 includes a body portion 101, a first limiting ring 102, and a second limiting ring 103. The body portion 101 is provided with a fixing hole 104 for fixing the damping body 100. The first limiting ring 102 and the second limiting ring 103 are respectively located at both ends of the body portion 101 along the axial direction of the fixing hole 104 and are connected to the outer peripheral wall of the body portion 101. The first limiting ring 102 is located above the second limiting ring 103 and is arranged at intervals. A mounting groove 111 is defined between the first limiting ring 102 and the second limiting ring 103. The mounting groove 111 is used to mount a shelf or mounting bracket 300.

[0041] The shock-absorbing body 100 is provided with multiple shock-absorbing holes 105, which are respectively located in at least one of the body portion 101, the first limiting ring 102, and the second limiting ring 103. The shock-absorbing holes 105 can absorb and disperse impact energy, thereby enhancing the shock-absorbing body 100's ability to buffer vibrations, improving its shock absorption effect, reducing the transmission of motor vibrations, and thus reducing noise. Simultaneously, the reduced vibration lowers the risk of component loosening and wear caused by vibration, which helps improve the structural stability of the refrigerator's interior and extends its lifespan.

[0042] It should be noted that the cross-section of the damping hole 105 can be circular, as circular holes are easy to process. It can also be elliptical, rectangular, or polygonal, etc. Different shapes and sizes of damping holes 105 can provide more possibilities in terms of appearance design or special functional requirements. As long as the damping hole 105 can meet the damping requirements, there are no specific restrictions on the shape and size of the damping hole 105. The shape of the damping hole 105 can be changed according to actual needs.

[0043] Reference Figures 4 to 6 As shown, the plurality of damping holes 105 include a first damping hole 1051, a second damping hole 1052, and a third damping hole 1053. The number of the first damping holes 1051, the second damping holes 1052, and the third damping holes 1053 are all multiple. The plurality of first damping holes 1051 are provided on the body part 101 and are arranged at intervals along the circumference of the fixing hole 104. The plurality of second damping holes 1052 are provided on the first limiting ring 102 and are arranged at intervals along the circumference of the fixing hole 104. The plurality of third damping holes 1053 are provided on the second limiting ring 103 and are arranged at intervals along the circumference of the fixing hole 104. There are four first damping holes 1051, four second damping holes 1052, and four third damping holes 1053. The four first damping holes 1051 are located on the main body 101, the four second damping holes 1052 are located on the first limiting ring 102, and the four third damping holes 1053 are located on the second limiting ring 103. The first damping holes 1051, the second damping holes 1052, and the third damping holes 1053 work together to absorb and disperse impact energy, thereby improving the damping effect of the damping body 100.

[0044] It should be noted that this utility model is not limited to providing only four first damping holes 1051, four second damping holes 1052, and four third damping holes 1053. Depending on the actual application scenario and requirements, the number of first damping holes 1051, second damping holes 1052, and third damping holes 1053 can be flexibly adjusted to one or more to flexibly adapt to the damping requirements of various damping bodies 100, so as to improve the damping effect of the damping components and reduce the transmission of motor vibration.

[0045] In some embodiments of this utility model, the damping holes 105 are all first damping holes 1051. Multiple first damping holes 1051 are provided on the body part 101 and arranged at intervals along the circumference of the fixing hole 104. Multiple first damping holes 1051 are used to enhance the damping effect of the damping body 100. The first damping holes 1051 penetrate at least one of the two end faces of the body part 101 that are axially opposite to each other, which can improve the damping effect of the damping component to a certain extent, reduce the transmission of vibration, and effectively reduce noise.

[0046] In some other embodiments of this utility model, the damping holes 105 are all second damping holes 1052. Multiple second damping holes 1052 are provided on the first limiting ring 102 and arranged at intervals along the circumference of the fixing hole 104. Multiple second damping holes 1052 are used to enhance the damping effect of the damping body 100. The regular distribution of multiple second damping holes 1052 improves the utilization rate of the damping body 100 and improves the damping effect. The second damping holes 1052 penetrate at least one of the two end faces of the first limiting ring 102 that are axially opposite to each other, which can improve the damping effect of the damping assembly to a certain extent, reduce the transmission of vibration, and effectively reduce noise.

[0047] In other embodiments of this utility model, the damping holes 105 are all third damping holes 1053. Multiple third damping holes 1053 are provided on the second limiting ring 103 and arranged at intervals along the circumference of the fixing hole 104. The multiple third damping holes 1053 are regularly distributed among each other, which improves the utilization rate of the damping body 100, can improve the damping effect of the damping component to a certain extent, reduce the transmission of vibration, and effectively reduce noise.

[0048] In some embodiments of this utility model, reference is made to Figure 4 As shown, it can be understood that a portion of the multiple damping holes 105 are first damping holes 1051, and the other portion are second damping holes 1052. There are multiple first damping holes 1051 and multiple second damping holes 1052. Multiple first damping holes 1051 are located on the main body 101 and arranged at intervals along the circumference of the fixing hole 104. Multiple second damping holes 1052 are located on the first limiting ring 102 and arranged at intervals along the circumference of the fixing hole 104. The multiple first damping holes 1051 and multiple second damping holes 1052 are arranged alternately along the circumference of the fixing hole 104, resulting in a more uniform damping capacity of the damping body 100 in the circumferential direction. The multiple first damping holes 1051 and multiple second damping holes 1052 work together to improve the damping effect of the damping body 100, reduce vibration transmission, and effectively reduce noise.

[0049] In other embodiments of this utility model, reference is made to Figure 5As shown, it can be understood that a portion of the multiple damping holes 105 are first damping holes 1051, and the other portion are third damping holes 1053. There are multiple first damping holes 1051 and multiple third damping holes 1053. Multiple first damping holes 1051 are located on the main body 101 and arranged at intervals along the circumference of the fixing hole 104. Multiple third damping holes 1053 are located on the second limiting ring 103 and arranged at intervals along the circumference of the fixing hole 104. The multiple first damping holes 1051 and multiple third damping holes 1053 are arranged alternately and at intervals along the circumference of the fixing hole 104, resulting in a more uniform damping capacity of the damping body 100 in the circumferential direction. The multiple first damping holes 1051 and multiple third damping holes 1053 work together to improve the damping effect of the damping body 100, reduce vibration transmission, and effectively reduce noise.

[0050] In some embodiments of this utility model, it is understood that a portion of the plurality of damping holes 105 are second damping holes 1052, and another portion are third damping holes 1053. The number of both second damping holes 1052 and third damping holes 1053 is plurality. The plurality of second damping holes 1052 are located on the first limiting ring 102, and the plurality of third damping holes 1053 are located on the second limiting ring 103. The plurality of second damping holes 1052 and the plurality of third damping holes 1053 are arranged alternately and at intervals along the circumference of the fixing hole 104. This makes the damping capacity of the damping body 100 more uniform in the circumferential direction. The plurality of second damping holes 1052 and the plurality of third damping holes 1053 are regularly distributed, resulting in a compact structure. The plurality of second damping holes 1052 and the plurality of third damping holes 1053 work together to improve the damping effect of the damping body 100, reduce vibration transmission, and effectively reduce noise.

[0051] Furthermore, in some embodiments of this utility model, the first damping hole 1051 penetrates one end face of the main body 101 that is axially opposite to that of the fixing hole 104, that is, it penetrates the upper or lower end face of the main body 101. The damping body 100 can reduce vibration by changing the local mass distribution and stiffness through the first damping hole 1051, thereby improving the damping effect of the damping body 100.

[0052] In some other embodiments of this utility model, the second damping hole 1052 penetrates one end face of the first limiting ring 102 that is axially opposite to that of the fixing hole 104, i.e., the upper or lower end face of the first limiting ring 102. The damping body 100 can reduce vibration by changing the local mass distribution and stiffness through the second damping hole 1052, thereby improving the damping effect of the damping body 100.

[0053] In other embodiments of this utility model, the third damping hole 1053 penetrates one end face of the second limiting ring 103 that is axially opposite to that of the fixing hole 104, that is, it penetrates the upper or lower end face of the second limiting ring 103. The damping body 100 can reduce vibration by changing the local mass distribution and stiffness through the third damping hole 1053, thereby improving the damping effect of the damping body 100.

[0054] In some other embodiments of this utility model, the first damping hole 1051 penetrates the two end faces of the main body 101 that are opposite to each other along the axial direction of the fixing hole 104. That is, the first damping hole 1051 is a through hole. The through hole can better absorb and disperse impact energy, enhance the damping body 100's ability to buffer vibration, and improve the damping effect of the damping body 100.

[0055] In some embodiments of this utility model, the second damping hole 1052 penetrates the two end faces of the first limiting ring 102 that are opposite to each other along the axial direction of the fixing hole 104. That is, the second damping hole 1052 is a through hole. The through hole can better absorb and disperse impact energy, enhance the damping capacity of the damping body 100 to vibration, and improve the damping effect of the damping body 100.

[0056] In some other embodiments of this utility model, the third damping hole 1053 penetrates the two end faces of the second limiting ring 103 that are opposite to each other along the axial direction of the fixing hole 104. That is, the third damping hole 1053 is a through hole. The through hole can better absorb and disperse impact energy, enhance the damping capacity of the damping body 100 to vibration, and improve the damping effect of the damping body 100.

[0057] In other embodiments, including the first damping hole 1051 and the second damping hole 1052, the plurality of first damping holes 1051 and the plurality of second damping holes 1052 may be distributed radially correspondingly in the fixing hole 104, that is, the center of the first damping hole 1051 and the center of the second damping hole 1052 are on the same straight line as the center of the fixing hole 104. The regular distribution of the plurality of first damping holes 1051 and the plurality of second damping holes 1052 can effectively enhance the damping effect of the damping body 100, reduce the transmission of vibration, and effectively reduce noise.

[0058] In this embodiment, refer to Figure 4 As shown, multiple first damping holes 1051 and multiple second damping holes 1052 are arranged alternately and at intervals in the circumferential direction of the fixing hole 104, making the damping capacity of the damping body 100 more uniform in the circumferential direction. The regular distribution of the multiple first damping holes 1051 and multiple second damping holes 1052 can effectively enhance the damping effect of the damping body 100, reduce the transmission of vibration, and effectively reduce noise.

[0059] In some embodiments of this utility model, reference is made to Figure 2As shown, the main body 101, the first limiting ring 102 and the second limiting ring 103 are integrally formed to facilitate the processing of the second damping hole 1052 and the third damping hole 1053. The integrally formed structure is more stable and can better increase the stability of motor installation, preventing the damping function from failing due to loose connections between components during severe vibration.

[0060] Reference Figure 6 As shown, in the embodiment including the second damping hole 1052 and the third damping hole 1053, the plurality of third damping holes 1053 and the plurality of second damping holes 1052 can also be arranged coaxially, which facilitates the machining of the second damping holes 1052 and the third damping holes 1053 by the cutting tool, reduces the tool positioning once, and improves production efficiency. The plurality of second damping holes 1052 and the plurality of third damping holes 1053 are regularly distributed and have a compact structure, which is conducive to improving the damping effect of the damping body 100. Furthermore, the plurality of second damping holes 1052 and the plurality of third damping holes 1053 work together to reduce the transmission of vibration and effectively reduce noise.

[0061] It is understandable that the inner diameter of the third damping hole 1053 is equal to that of the second damping hole 1052. Damping holes 105 with equal inner diameters can be machined using the same processing technology and tools, reducing the number of tool changes and adjustments to processing parameters, thus improving production efficiency. Furthermore, when cleaning or repairing the damping holes 105, tools of the same specifications can be used, reducing production and maintenance costs.

[0062] It should be noted that the inner diameters of the third damping hole 1053 and the second damping hole 1052 may not be equal, and the third damping hole 1053 and the second damping hole 1052 may also be arranged non-coaxially. The specific arrangement can be changed according to actual needs.

[0063] Reference Figure 2 and Figure 3 As shown, the vibration damping assembly also includes a bushing 106 and a fastener 109. The bushing 106 is installed on the inner wall of the fixing hole 104, and the axial length of the bushing 106 is equal to or less than the axial length of the fixing hole 104. The fastener 109 passes through the bushing 106. The material of the bushing 106 includes, but is not limited to, brass, bronze, stainless steel, and carbon steel. The bushing 106 can enhance the structural stability of the vibration damping assembly and the installation stability of the motor.

[0064] In some embodiments of this utility model, it is understood that the Shore hardness of the damping body 100 is between 40HA and 60HA. The Shore hardness can be measured using a Shore A hardness tester. The Shore A hardness tester has a steel indenter of a specific shape, which is vertically pressed into the surface of the damping body 100 under test force. When the indenter surface is completely in contact with the surface of the damping body 100, the tip of the indenter extends a certain length relative to the indenter surface, i.e., the depth to which the indenter penetrates the object being tested. The magnitude of this extension length characterizes the Shore hardness. Having a Shore hardness between 40HA and 60HA for the damping body 100 increases the structural stability of the damping body 100, preventing excessive deformation or even damage, ensuring good damping performance, and enhancing the overall structural stability of the damping assembly.

[0065] A second aspect of this utility model provides a storage cabinet, as described below. Figure 1 and Figure 3 As shown, the locker includes a mounting bracket 300, a shelf, and a shock-absorbing component according to any of the above embodiments. The mounting bracket 300 is installed inside the locker. The shelf typically includes a shelf, a mounting base 200, a drive shaft, a drive component, and a transmission component. The mounting base 200 is used to install the drive component, drive shaft, and transmission component. The shelf is snapped into the mounting groove 111, that is, the mounting base 200 is snapped into the mounting groove 111. The shock-absorbing component also includes a fastener 109, which passes through the fixing hole 104 and is connected to the mounting bracket 300, thereby fixing the shock-absorbing body 100 between the mounting bracket 300 and the mounting base 200. Since the drive component will generate vibration when it is working, this reduces the vibration transmitted to the mounting bracket 300 and the locker, thus reducing noise.

[0066] Because the locker employs all the technical solutions of the shock-absorbing components described in the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments. During use, the locker effectively reduces the transmission of vibrations caused by the operation of components such as motors, reducing problems such as component loosening and wear caused by vibration, thus extending the locker's service life. Furthermore, it significantly reduces noise, providing users with a quieter and more comfortable environment, effectively avoiding inconvenience caused by noise interference, improving the overall quality and user experience of the locker, and enhancing product competitiveness.

[0067] Specifically, refer to Figure 1 and Figure 3 As shown, it can be understood that there are two sets of shock-absorbing components, with the motor positioned in the space between the two sets of shock-absorbing components. This makes the overall structure more stable and further reduces the transmission of vibration. The reduction in vibration lowers the risk of components loosening or wearing due to vibration, which helps improve the structural stability of the refrigerator's interior, extends its lifespan, and enhances the product competitiveness of the storage cabinet.

[0068] In some other embodiments of this utility model, the mounting bracket 300 is snapped into the mounting groove 111, which can quickly and initially fix the shock-absorbing body 100. The fastener 109 passes through the fixing hole 104 and is connected to the shelf, that is, the fastener 109 is connected to the mounting base 200 to fix the shock-absorbing body 100 between the mounting bracket 300 and the mounting base 200, thereby reducing the vibration transmitted to the mounting bracket 300 and the storage cabinet and reducing noise.

[0069] Specifically, the mounting base 200 is provided with a first mounting hole 201, a second mounting hole 202, and a third mounting hole 203. A drive shaft, used to drive the lifting and lowering of the shelf, is mounted in the first mounting hole 201. The drive component can be a motor, which is mounted in the second mounting hole 202. The drive component and the drive shaft are connected via a transmission component. The shock-absorbing components are mounted in the third mounting hole 203. There are two third mounting holes 203, each corresponding to one of the two shock-absorbing components.

[0070] Specifically, refer to Figure 2 As shown, the mounting bracket 300 is provided with two connecting posts 301, each corresponding to one of the two shock-absorbing components. The connecting posts 301 are hollow and have internal threads. The fasteners 109 are hexagonal bolts; the hexagonal bolt heads provide a good wrench grip surface for easy tightening or loosening. The fasteners 109 are threadedly connected to the connecting posts 301 to fix the shock-absorbing body 100 to the mounting bracket 300.

[0071] It should be noted that fastener 109 can also be a rivet or a pin. During installation, the rivet is passed through the fixing hole 104 to fasten the shock-absorbing component, mounting bracket 300, and mounting base 200 together. The rivet connection is firm and has good sealing performance.

[0072] Reference Figure 2 and Figure 3 As shown, the vibration damping assembly also includes a vibration damping pad 107. The vibration damping pad 107 has two clearance holes 110, which are used to allow clearance between the two connecting posts 301. Common materials for the vibration damping pad 107 include rubber, polyurethane, fluororubber, silicone, or other vibration damping materials. The material of the vibration damping pad 107 is not limited here. The vibration damping pad 107 has good elasticity and can effectively absorb vibration. The vibration damping pad 107 is located between the mounting bracket 300 and the cabinet shell. When the motor vibrates, the vibration damping pad 107 can buffer the vibration. The vibration damping pad 107 can undergo elastic deformation to absorb transmitted vibration, avoiding the aggravation of vibration and noise generation due to hard collisions between components, thereby further improving the vibration damping and noise reduction effect of the entire vibration damping assembly and creating favorable conditions for a low-noise environment for the refrigerator.

[0073] In this embodiment of the invention, two shock-absorbing components are shown in the case of the storage cabinet. This arrangement effectively enhances the shock absorption effect and improves the installation stability of the motor. However, this invention is not limited to only two shock-absorbing components. Depending on the actual application scenario and requirements, the number of shock-absorbing components can be flexibly adjusted to one or more to flexibly adapt to the shock absorption needs of various storage cabinets, thereby reducing the noise generated by the storage cabinet due to vibration and improving the overall quality and user experience of the storage cabinet.

[0074] Specifically, in some embodiments of this utility model, the mounting bracket 300 is installed on the storage cabinet, and the shock-absorbing pad 107 is disposed between the mounting bracket 300 and the storage cabinet. The thickness of the mounting base 200 matches the mounting groove 111, and the mounting base 200 is snapped into the mounting groove 111, that is, the mounting base 200 is located between the first limiting ring 102 and the second limiting ring 103. The shock-absorbing body 100 is threadedly connected to the mounting bracket 300 by bolts. A bushing 106 is provided between the bolts and the shock-absorbing body 100 to enhance the stability of the overall structure. A washer 108 is also provided between the bolts and the first limiting ring 102 to fill the gap between the bolts and the first limiting ring 102, so that the shock-absorbing body 100 is tightly fixed to the mounting bracket 300, improving the overall structural stability between the shock-absorbing components, reducing the transmission of motor vibration, and thus reducing noise. Due to the reduction of vibration, the risk of loosening and wear of components caused by vibration can be reduced, which is conducive to improving the structural stability of the refrigerator, extending the life of the refrigerator, and improving the product competitiveness of the storage cabinet.

[0075] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
