Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a support component and refrigeration equipment. Background Technology

[0002] Air conditioning and other refrigeration equipment have compressors, which vibrate during operation. To absorb these vibrations, damping pads and support bolts are typically installed at the bottom of the compressor. The support bolts are fixed to the casing of the refrigeration equipment, and the damping pads are fitted around the support components.

[0003] However, the fit between the support bolts and damping pads currently available on the market is difficult to simultaneously achieve both the manufacturability of the damping pads and their damping performance. Utility Model Content

[0004] In view of this, this application provides a support component and a cooling device that can simultaneously take into account the manufacturability and shock absorption performance of the shock-absorbing pad.

[0005] Specifically, the following technical solutions are included:

[0006] In a first aspect, this application provides a support component, including:

[0007] The shock-absorbing pad has a first through hole, a second through hole and a third through hole connected in sequence. The diameters D1 of the first through hole, D2 of the second through hole and D3 of the third through hole satisfy: D1 < D3 < D2.

[0008] The support member includes a first support segment and a second support segment connected in sequence. The first support segment is adapted to the first through hole, and the second support segment is adapted to the third through hole. The diameter of the second support segment is larger than the diameter of the first support segment.

[0009] In the technical solution of this application, since the diameter D3 of the third through hole is larger than the diameter D1 of the first through hole and smaller than the diameter D2 of the second through hole, demolding can be performed from the side where the relatively larger diameter third through hole is located during the manufacturing process of the shock-absorbing pad, allowing the mold to smoothly detach from the second through hole and ensuring the manufacturability of the shock-absorbing pad. Since the first support section is adapted to the first through hole and the second support section is adapted to the third through hole, the difference between the gap between the first support section and the first through hole and the gap between the second support section and the third through hole is reduced. In other words, the maximum gap between the support and the shock-absorbing pad is reduced, which helps to ensure that the compressor will not have excessive lateral displacement relative to the casing of the refrigeration equipment, improves the reliability and stability of the compressor under start-up, shutdown, or transportation conditions, and also ensures that the diameters of the first, second, and third through holes are all within a suitable size range, without having to reduce the size of the first, second, and third through holes to reduce the fitting clearance between the support and the shock-absorbing pad, thus helping to ensure that the shock-absorbing pad has sufficient shock absorption performance.

[0010] In one possible implementation, the shock-absorbing pad includes a connected mounting portion and a main body portion. The mounting portion is used to cooperate with the support foot of the compressor of the refrigeration equipment, and the main body portion is used to cooperate with the housing of the refrigeration equipment. The first through hole penetrates the mounting portion, and the second through hole and the third through hole are both located in the main body portion.

[0011] In the technical solution of this application, the first through hole is located on the side near the support foot of the compressor, and the third through hole is located on the side near the bottom plate of the housing. By setting the diameter of the first through hole to be smaller than the diameters of the second and third through holes, it is beneficial to increase the thickness L1 of the mounting part and ensure the connection stability between the support foot and the shock-absorbing pad. Furthermore, since the diameter of the third through hole is larger than the diameter of the first through hole, and the diameter of the second through hole is related to the diameter of the third through hole due to the demolding requirements of the shock-absorbing pad, the diameter of the second through hole can be set to be larger, increasing the diameter difference between the second and first through holes, reducing the distance L2 between the hole wall of the second through hole and the support point (i.e., the area where the inner wall of the mounting hole mates with the mounting part), reducing the rigidity of the main body, and improving the elasticity and shock absorption performance of the shock-absorbing pad.

[0012] In one possible implementation, the outer peripheral surface of the main body is recessed with a groove, which is arranged around the central axis of the main body.

[0013] In the technical solution of this application, by setting the groove, on the one hand, the amount of material used and the material cost of the shock-absorbing pad are reduced, and on the other hand, it is beneficial to reduce the wall thickness of the main body, improve the elastic deformation capacity of the main body, reduce the stiffness of the main body, and improve the shock absorption performance of the shock-absorbing pad.

[0014] In one possible implementation, the support further includes a threaded segment connected to the first support segment and located at one end of the first support segment opposite to the second support segment, the threaded segment having external threads for engaging with a nut.

[0015] In the technical solution of this application, by setting a threaded section, the nut can engage with the external thread of the threaded section through its own internal thread, thereby playing an anti-disengagement role at the upper end of the support and preventing the support from moving downward and disengaging from the shock-absorbing pad.

[0016] In one possible implementation, the diameter d1 of the threaded segment, the diameter d2 of the first support segment, and the diameter d3 of the second support segment satisfy: d1 < d2 < d3.

[0017] In the technical solution of this application, by setting the diameter d2 of the first support section to be smaller than the diameter d3 of the second support section, the dimensional relationship between the first through hole and the third through hole is adapted, which helps to reduce the difference between the first gap and the second gap, ensuring that the compressor will not have excessive lateral displacement relative to the casing of the refrigeration equipment. By setting the diameter d1 of the threaded section to be smaller than the diameter d2 of the first support section, a step is formed between the threaded section and the first support section, providing a limiting effect for the nut.

[0018] In one possible implementation, the diameter D1 of the first through hole and the diameter d2 of the first support segment satisfy: 0mm < D1 - d2 ≤ 2mm; and / or, the diameter D3 of the third through hole and the diameter d3 of the second support segment satisfy:

[0019] 0mm < D3 - d3 ≤ 2mm.

[0020] In the technical solution of this application, by setting D1-d2>0 and / or D3-d3>0, a clearance fit is achieved between the support and the damping pad, which reduces the transmission of vibration energy between the support and the damping pad, thus alleviating the vibration and noise of the casing. By setting D1-d2≤2mm and / or D3-d3≤2mm, a small clearance fit is achieved between the support and the damping pad, making the single-sided gap between the support and the damping pad less than or equal to 1mm. This serves two purposes: firstly, it positions the rubber pad during installation; secondly, it limits the lateral displacement of the compressor, ensuring the reliability of the compressor during transportation, drops, start-up, and shutdown.

[0021] In one possible implementation, the height H1 of the second through hole and the height H0 of the damping pad satisfy: 0.5H0≤H1<H0.

[0022] In the technical solution of this application, this setting ensures that the second through hole has a large height in the damping pad, which helps to reduce the stiffness of the support section of the damping pad and improve the elastic deformation capacity and damping performance of the damping pad.

[0023] In one possible implementation, the sum of the heights of the first support segment and the second support segment is h1, satisfying: 1.5mm ≤ h1 - H0 ≤ 3mm.

[0024] In the technical solution of this application, by means of this setting, the upper end surface of the first support section is higher than the upper end surface of the shock-absorbing pad, which can avoid the nut sleeved on the threaded section from being damaged by contact friction with the shock-absorbing pad, and is conducive to improving the durability and service life of the support component.

[0025] In one possible implementation, the diameter D2 of the second through hole and the diameter D3 of the third through hole satisfy: 1.1D3≤D2≤1.6D3.

[0026] In the technical solution of this application, this arrangement is beneficial for simultaneously considering the damping performance and manufacturability of the shock-absorbing pad. With the diameter D3 of the third through hole remaining constant, when D2 < 1.1D3, the distance L2 between the wall of the second through hole and the support point is larger, increasing the stiffness of the shock-absorbing pad but decreasing its elastic deformation capacity and damping performance. When D2 > 1.6D3, the size difference between the second and third through holes is significant, hindering the demolding operation of the shock-absorbing pad during manufacturing and affecting its manufacturability.

[0027] In one possible implementation, the diameter D1 of the first through hole and the diameter D3 of the third through hole satisfy: 1.1D1≤D3≤1.3D1.

[0028] In the technical solution of this application, this arrangement helps to simultaneously consider the damping performance and manufacturing cost of the shock-absorbing pad. With the diameter D1 of the first through hole remaining constant, when D3 < 1.1D1, to meet the demolding requirements of the shock-absorbing pad, the diameter D2 of the second through hole decreases with the diameter D3 of the third through hole. This results in a larger distance L2 between the hole wall of the second through hole and the support point, increasing the stiffness of the shock-absorbing pad and worsening its elastic deformation capacity and damping performance. When D3 > 1.3D1, it increases the material cost of the second support section.

[0029] Secondly, this application provides a refrigeration device, which includes a housing, a compressor, and a support assembly provided in any embodiment of the first aspect. The compressor is disposed in the housing and has a support foot with a mounting hole. The support assembly is fixed to the housing and is connected to the mounting hole. Attached Figure Description

Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The directional terms used in the embodiments of this application, such as "up," "down," and "side," are generally based on the relative relationships shown in the figures. These directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute directions. When the product is placed in different orientations, the orientation may change; for example, "up" and "down" may be interchanged.

[0045] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0046] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0047] In related technologies, such as Figure 1 As shown, the shock-absorbing pad 300 has a demolding hole 301, a shock-absorbing hole 302, and a mating hole 303 connected in sequence. The demolding hole 301 is located at one end of the shock-absorbing pad 300 near the support foot 200 of the compressor. The mating hole 303 is located on one side of the bottom plate 101 near the housing 100. The mating hole 303 is used to fit with the support bolt 400. The diameter of the shock-absorbing hole 302 is larger than the diameter of the demolding hole 301, and the diameter of the demolding hole 301 is larger than the diameter of the mating hole 303. The large clearance between the support bolt 400 and the demolding hole 301 makes the compressor prone to excessive stress, shaking, collisions, and other adverse conditions during start-up, shutdown, or transportation. If the diameter of the demolding hole 301 is reduced, the diameter of the damping hole 302 will also be reduced to ensure the smooth demolding of the damping pad 300. This would increase the thickness and rigidity of the damping pad 300, resulting in a poorer damping effect. It is difficult to simultaneously achieve both the manufacturability and damping performance of the damping pad 300.

[0048] In view of the above situation, this application provides a support component and a cooling device that can simultaneously take into account the manufacturability and shock absorption performance of the shock-absorbing pad.

[0049] like Figure 2 As shown in the embodiment of this application, the support component includes a shock-absorbing pad 1 and a support member 2.

[0050] The support components can be used in refrigeration equipment or other devices that require vibration damping and support. The refrigeration equipment can be air conditioners, refrigerators, refrigerated trucks, ice makers or other devices with compressors.

[0051] The shock-absorbing pad 1 has a first through hole 11, a second through hole 12 and a third through hole 13 connected in sequence. The diameters D1 of the first through hole 11, D2 of the second through hole 12 and D3 of the third through hole 13 satisfy: D1 < D3 < D2.

[0052] The support member 2 includes a first support section 21 and a second support section 22 connected in sequence. The first support section 21 is adapted to the first through hole 11, and the second support section 22 is adapted to the third through hole 13. The diameter of the second support section 22 is larger than the diameter of the first support section 21.

[0053] The shock-absorbing pad 1 is made of rubber, silicone, or other materials with elastic deformation capabilities or flexibility. For example... Figure 3 As shown, the first through hole 11 penetrates the upper end face of the shock-absorbing pad 1, the third through hole 13 penetrates the lower end face of the shock-absorbing pad 1, and the second through hole 12 is located between the first through hole 11 and the third through hole 13.

[0054] In the shock-absorbing pad 1, the diameter of the second through hole 12 is the largest, followed by the third through hole 13. The size difference between the second through hole 12 and the third through hole 13 is smaller than the size difference between the second through hole 12 and the first through hole 11. During the manufacturing process of the shock-absorbing pad 1, it can be demolded from one side of the third through hole 13, so that the shock-absorbing pad 1 can be smoothly removed from the mold, ensuring the manufacturability of the shock-absorbing pad 1.

[0055] The first support segment 21 is adapted to the first through hole 11, and the second support segment 22 is adapted to the third through hole 13, meaning that: the shape of the first support segment 21 is the same as that of the first through hole 11, and the size of the first support segment 21 is the same as that of the first through hole 11 or the size of the first through hole 11 is slightly larger than the size of the first support segment 21; the shape of the second support segment 22 is the same as that of the third through hole 13, and the size of the second support segment 22 is the same as that of the third through hole 13 or the size of the third through hole 13 is slightly larger than the size of the second support segment 22.

[0056] For example, the first through hole 11, the second through hole 12 and the third through hole 13 are three circular holes arranged coaxially, and the first support section 21 and the second support section 22 are two cylinders arranged coaxially.

[0057] In related technologies, such as Figure 1As shown, the diameter of the portion of the support bolt 400 located within the shock-absorbing pad 300 is the same everywhere. Due to the large dimensional difference between the demolding hole 301 and the mating hole 303, when the mating hole 303 is matched with the support bolt 400, the gap between the support bolt 400 and the demolding hole 301 is relatively large (e.g., more than 4mm). This may cause the compressor to shift significantly during start-up, shutdown, or transportation, resulting in excessive stress. In severe cases, this may lead to the failure of the refrigeration equipment. Furthermore, an excessively large gap may cause the compressor and piping to tilt and collide with the casing 100 of the refrigeration equipment when it is dropped.

[0058] In the technical solution of this application, the gap between the first support section 21 and the first through hole 11 is denoted as the first gap, and the gap between the second support section 22 and the third through hole 13 is denoted as the second gap. By setting the first support section 21 to be adapted to the first through hole 11 and the second support section 22 to be adapted to the third through hole 13, it is beneficial to reduce the size of the first gap and the second gap, and also beneficial to reduce the difference between the first gap and the second gap, so as to reduce the maximum gap between the support member 2 and the shock-absorbing pad 1, which is beneficial to ensure that the compressor does not generate excessive lateral movement relative to the casing 100 of the refrigeration equipment (i.e., Figure 2 The horizontal displacement improves the reliability and stability of the compressor during start-up, shutdown, or transport conditions. Furthermore, since the first support section 21 and the second support section 22 are respectively adapted to the first through hole 11 and the third through hole 13, the dimensions of the first through hole 11, the second through hole 12, and the third through hole 13 can be set within a range that allows the shock-absorbing pad 1 to have optimal flexibility / elastic deformation capability, ensuring that the shock-absorbing pad 1 has good buffering and damping capacity.

[0059] In the support assembly provided in this application embodiment, since the diameter D3 of the third through hole 13 is larger than the diameter D1 of the first through hole 11 and smaller than the diameter D2 of the second through hole 12, demolding can be performed from the side where the relatively larger diameter third through hole 13 is located during the manufacturing process of the shock-absorbing pad 1, allowing the mold to smoothly detach from the second through hole 12 and ensuring the manufacturability of the shock-absorbing pad 1. Since the first support section 21 is adapted to the first through hole 11 and the second support section 22 is adapted to the third through hole 13, the gap between the first support section 21 and the first through hole 11, and the gap between the second support section 22 and the third through hole 13, are all within acceptable limits. The reduction in the gap between the support member 2 and the shock-absorbing pad 1, that is, the reduction in the maximum gap between the support member 2 and the shock-absorbing pad 1, helps to ensure that the compressor does not have excessive lateral displacement relative to the housing 100 of the refrigeration equipment, improves the reliability and stability of the compressor during start-up, shutdown or transportation conditions, and also ensures that the diameters of the first through hole 11, the second through hole 12 and the third through hole 13 are all within a suitable size range, without having to reduce the size of the first through hole 11, the second through hole 12 and the third through hole 13 in order to reduce the fitting gap between the support member 2 and the shock-absorbing pad 1, which helps to ensure that the shock-absorbing pad 1 has sufficient shock absorption performance.

[0060] In some embodiments, the shock-absorbing pad 1 includes a mounting portion 14 and a main body portion 15 connected together. The mounting portion 14 is used to cooperate with the support foot 200 of the compressor of the refrigeration equipment, and the main body portion 15 is used to cooperate with the housing 100 of the refrigeration equipment. A first through hole 11 penetrates the mounting portion 14, and a second through hole 12 and a third through hole 13 are both located in the main body portion 15.

[0061] Mounting part 14 and main body part 15 are along the axial direction of the shock-absorbing pad 1 (i.e. Figure 3 The third through hole 13 penetrates the lower end face of the main body 15 and is distributed in the vertical direction.

[0062] The compressor's support feet 200 have mounting holes 201. The shock-absorbing pad 1 is installed in the mounting holes 201 through the mounting part 14, which is at least partially located in the mounting holes 201. The main body 15 is fixed to the housing 100 of the refrigeration equipment, specifically to the base plate 101 of the housing 100.

[0063] Please refer to Figure 2 and Figure 4The first through hole 11 is located on the side near the support foot 200 of the compressor, and the third through hole 13 is located on the side near the base plate 101 of the housing 100. By setting the diameter of the first through hole 11 to be smaller than the diameters of the second through hole 12 and the third through hole 13, it is beneficial to increase the thickness L1 of the mounting part 14 and ensure the connection stability between the support foot 200 and the shock-absorbing pad 1. Furthermore, since the diameter of the third through hole 13 is larger than the diameter of the first through hole 11, and the diameter of the second through hole 12 is related to the diameter of the third through hole 13 due to the demolding requirements of the shock-absorbing pad 1, the diameter of the second through hole 12 can be set to be larger, increasing the diameter difference between the second through hole 12 and the first through hole 11, reducing the distance L2 between the hole wall of the second through hole 12 and the support point (i.e., the position where the inner wall of the mounting hole 201 mates with the mounting part 14), reducing the rigidity of the main body 15, and improving the elasticity and shock absorption performance of the shock-absorbing pad 1.

[0064] Optionally, such as Figure 2 and Figure 3 As shown, the shock-absorbing pad 1 also includes a boss portion 16, which is connected to the mounting portion 14 and located at the end of the mounting portion 14 opposite to the main body portion 15. The outer diameter of the boss portion 16 is larger than the outer diameter of the mounting portion 14, and the outer diameter of the main body portion 15 is larger than the outer diameter of the mounting portion 14. With this arrangement, the boss portion 16 and the main body portion 15 are clamped on both sides in the thickness direction of the support foot 200, which plays a limiting role in the axial direction of the shock-absorbing pad 1.

[0065] In some embodiments, the outer peripheral surface of the main body 15 is recessed with a groove 151, and the groove 151 is arranged around the central axis of the main body 15.

[0066] The number of grooves 151 can be one or more, for example Figure 3 As shown, the outer peripheral surface of the main body 15 is provided with two grooves 151, which are spaced apart along the axial direction of the shock-absorbing pad 1.

[0067] By setting the groove 151, on the one hand, the amount of material used and the material cost of the shock-absorbing pad 1 are reduced, and on the other hand, it is beneficial to reduce the wall thickness of the main body 15, improve the elastic deformation capacity of the main body 15, reduce the stiffness of the main body 15, and improve the shock absorption performance of the shock-absorbing pad 1.

[0068] The groove 151 is annular and arranged around the central axis of the main body 15, which can improve the uniformity of stiffness in all parts of the main body 15 in the circumferential direction and improve the reliability of the shock-absorbing pad 1.

[0069] In some embodiments, the support member 2 further includes a threaded section 23, which is connected to the first support section 21 and is located at the end of the first support section 21 away from the second support section 22. The threaded section 23 is provided with an external thread for engaging with a nut.

[0070] like Figure 5 As shown, the threaded section 23 is located at the upper end of the first support section 21, and the second support section 22 is located at the lower end of the first support section 21. The threaded section 23, the first support section 21, and the second support section 22 are coaxially arranged.

[0071] By setting the threaded section 23, the nut can engage with the external thread of the threaded section 23 through its own internal thread, thereby playing an anti-disengagement role at the upper end of the support 2 and preventing the support 2 from moving downward and dislodging from the shock-absorbing pad 1.

[0072] Optionally, the support member 2 further includes a connecting part 24, which is connected to the second support section 22 and is located at the end of the second support section 22 away from the first support section 21. The diameter of the connecting part 24 is larger than the diameter of the second support section 22. The threaded section 23, the first support section 21, the second support section 22 and the connecting part 24 are coaxially arranged.

[0073] like Figure 2 As shown, the connecting part 24 is located on the side of the bottom plate 101 of the housing 100 away from the shock-absorbing pad 1 (i.e., Figure 2 Below the base plate 101, the larger diameter connecting part 24 increases the connection area between the support member 2 and the base plate 101, thereby improving the connection strength between the support member 2 and the housing 100. Simultaneously, the connecting part 24 acts as a limit at the lower end of the support member 2, preventing it from moving upwards and detaching from the shock-absorbing pad 1. Optionally, the connecting part 24 is welded to the base plate 101 of the housing 100 to achieve a stable connection between the support member 2 and the base plate 101.

[0074] In some embodiments, the diameter d1 of the threaded section 23, the diameter d2 of the first support section 21, and the diameter d3 of the second support section 22 satisfy the following condition: d1 < d2 < d3.

[0075] like Figure 6 As shown, the diameters of the threaded section 23, the first support section 21, and the second support section 22 increase sequentially.

[0076] In this embodiment, by setting the diameter d2 of the first support section 21 to be smaller than the diameter d3 of the second support section 22, the dimensional relationship between the first through hole 11 and the third through hole 13 is adapted, which helps to reduce the difference between the first gap and the second gap, ensuring that the compressor will not have excessive lateral displacement relative to the housing 100 of the refrigeration equipment. By setting the diameter d1 of the threaded section 23 to be smaller than the diameter d2 of the first support section 21, a step is formed between the threaded section 23 and the first support section 21, providing a limiting effect for the nut.

[0077] For example, the threaded section 23 is provided with an M6 thread, an M8 thread, or an M10 thread; the diameter d2 of the second through hole 12 is 8mm to 12mm, for example, the diameter of the second through hole 12 can be 8mm, 10mm, 12mm, etc.

[0078] In some embodiments, the diameter D1 of the first through hole 11 and the diameter d2 of the first support segment 21 satisfy: 0mm < D1 - d2 ≤ 2mm; and / or, the diameter D3 of the third through hole 13 and the diameter d3 of the second support segment 22 satisfy: 0mm < D3 - d3 ≤ 2mm.

[0079] By setting D1-d2>0 and / or D3-d3>0, a clearance fit is achieved between the support 2 and the damping pad 1, which can reduce the transmission of vibration energy between the support 2 and the damping pad 1 and alleviate the vibration and noise of the housing 100.

[0080] By setting D1-d2≤2mm and / or D3-d3≤2mm, a small clearance fit is achieved between the support 2 and the damping pad 1, making the single-sided gap between the support 2 and the damping pad 1 less than or equal to 1mm. On the one hand, it plays a positioning role in the installation of the damping pad 1, and on the other hand, it can limit the lateral displacement of the compressor, ensuring the reliability of the compressor in scenarios such as transportation, drops, start-up, and shutdown.

[0081] In some embodiments, the height H1 of the second through hole 12 and the height H0 of the damping pad 1 satisfy: 0.5H0≤H1<H0. It can be understood that the height of the second through hole 12 / dampening pad 1 is the dimension of the second through hole 12 / dampening pad 1 in the axial direction of the damping pad 1.

[0082] This arrangement ensures that the second through hole 12 has a relatively large height within the damping pad 1, which helps to reduce the stiffness of the main body 15 of the damping pad 1 and improve its elastic deformation capacity and damping performance. When H1 < 0.5H0, the damping pad 1 has high stiffness and poor damping performance.

[0083] The height H0 of the shock-absorbing pad 1 can be set according to factors such as the size of the space inside the housing 100. For example, in some embodiments, 25mm≤H0≤45mm.

[0084] In some embodiments, the height H2 of the third through hole 13 satisfies 5mm≤H2≤10mm.

[0085] In some embodiments, the sum of the heights of the first support segment 21 and the second support segment 22 is h1, satisfying: 1.5mm≤h1-H0≤3mm.

[0086] like Figure 1As shown, with this setting, the upper end face of the first support section 21 is higher than the upper end face of the shock-absorbing pad 1, which can prevent the nut sleeved on the threaded section 23 from contacting and rubbing against the shock-absorbing pad 1 and causing damage, which is beneficial to improving the durability and service life of the support assembly.

[0087] When the difference between h1 and H0 is less than 1.5mm, the nut is prone to contact and friction with the shock-absorbing pad 1, causing damage; when the difference between h1 and H0 is greater than 3mm, the height of the support 2 is too large, the material cost of the support 2 increases, and the space occupied in the housing 100 becomes larger, which can easily affect the assembly of other parts.

[0088] In some embodiments, the height of the first support segment 21 is h2, satisfying: 0.5h1≤h2

[0089] This configuration, while ensuring that the first support section 21 is compatible with the first through hole 11 and the second support section 22 is compatible with the third through hole 13, helps to reduce the material usage and manufacturing cost of the support component 2. When h2 < 0.5h1, the second support section 22, with its relatively large diameter, has a larger height, which increases the material usage and manufacturing cost of the support component 2.

[0090] In some embodiments, the height of the support member 2 is h0, which satisfies 8mm≤h0-h1≤14mm, that is, the sum of the heights of the threaded section 23 and the connecting part 24 is 8mm~14mm. When the threaded section 23 is provided with M6 thread, M8 thread or M10 thread, it ensures that the height of the threaded section 23 can be adapted to nuts of M6, M8 or M10 specifications.

[0091] In some embodiments, the diameter D2 of the second through hole 12 and the diameter D3 of the third through hole 13 satisfy: 1.1D3≤D2≤1.6D3.

[0092] This design allows for a balance between the damping performance and manufacturability of the shock-absorbing pad 1. With the diameter D3 of the third through hole 13 remaining constant, when D2 < 1.1D3, the distance L2 between the wall of the second through hole 12 and the support point is larger, increasing the stiffness of the shock-absorbing pad 1 but decreasing its elastic deformation capacity and damping performance. When D2 > 1.6D3, the dimensional difference between the second through hole 12 and the third through hole 13 is significant, hindering the demolding process of the shock-absorbing pad 1 during manufacturing and affecting its manufacturability.

[0093] In some embodiments, the diameter D1 of the first through hole 11 and the diameter D3 of the third through hole 13 satisfy: 1.1D1≤D3≤1.3D1.

[0094] ​This design helps to balance the damping performance of the shock-absorbing pad 1 with its manufacturing cost. With the diameter D1 of the first through hole 11 remaining constant, when D3 < 1.1D1, to meet the demolding requirements of the shock-absorbing pad 1, the diameter D2 of the second through hole 12 decreases with the diameter D3 of the third through hole 13. This results in a larger distance L2 between the hole wall of the second through hole 12 and the support point, increasing the stiffness of the shock-absorbing pad 1 and worsening its elastic deformation capacity and damping performance. When D3 > 1.3D1, it increases the material cost of the second support section 22.
