Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a shock-absorbing foot pad and refrigeration equipment. Background Art

[0002] In refrigerators, the foot pad assembly plays a role in vibration reduction, which can reduce the noise caused by the vibration of the compressor being transmitted to the cabinet of the refrigeration equipment through the machine feet. When the natural frequency of the foot pad assembly is close to the operating frequency of the compressor, most of the vibration excitation of the compressor foot will be transmitted to the cabinet through the foot pad assembly, which will then cause the cabinet to resonate and generate fundamental frequency resonance noise, affecting the user experience. Utility Model Content

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0004] In view of this, in the first aspect, the utility model proposes a shock-absorbing foot pad, comprising: a shock-absorbing pad body, an installation end surface on the shock-absorbing pad body for contacting the part to be shock-absorbed, a groove is provided on the installation end surface, and the groove is used to be arranged relative to the part to be shock-absorbed.

[0005] The shock-absorbing foot pad provided by the utility model is used to be installed on the part to be shock-absorbed. Specifically, the shock-absorbing foot pad is usually arranged between two groups of parts to be shock-absorbed. The shock-absorbing foot pad is used to absorb the vibration of the part to be shock-absorbed, thereby avoiding noise generated due to vibration between the two groups of parts to be shock-absorbed.

[0006] When the operating frequency of the part to be damped is close to the natural frequency of the damping pad, the damping effect of the damping pad is poor. At this time, the damping pad is easy to transmit the vibration. However, the contact area between the damping pad and the part to be damped will affect the resonance noise. Therefore, the resonance noise can be weakened by changing the contact area between the damping pad and the part to be damped.

[0007] Specifically, the shock-absorbing pad body has an installation end surface. When the shock-absorbing pad body and the part to be shock-absorbed are installed, the part to be shock-absorbed fits with the installation end surface on the shock-absorbing pad body. A groove is provided on the installation end surface, and the groove is arranged relative to the part to be shock-absorbed, that is, at the position where the groove is provided on the installation end surface, there is a gap between the part to be shock-absorbed and the shock-absorbing foot pad. Therefore, without changing the shape and size of the shock-absorbing foot pad, the contact area between the part to be shock-absorbed and the shock-absorbing foot pad is reduced, which is beneficial to reducing the fundamental frequency resonance noise between the part to be shock-absorbed and the shock-absorbing foot pad. The shock-absorbing foot pad can effectively absorb vibration, prevent resonance of two groups of parts to be shock-absorbed installed on the shock-absorbing foot pad, reduce noise during operation of the electrical appliance, and help improve user experience.

[0008] Moreover, by making grooves on the installation end surface, there is no need to make major changes to the shape and size of the shock-absorbing foot pad, which is conducive to reducing the difficulty of processing the shock-absorbing foot pad.

[0009] In addition, the shock-absorbing foot pad in the above technical solution provided by the utility model may also have the following additional technical features:

[0010] In some technical solutions, optionally, the groove includes an annular groove, and the annular groove is distributed along the circumference of the mounting end surface.

[0011] A groove is provided on the circumference of the mounting end surface. By increasing the area of ​​the groove, the contact area between the damped part and the damping pad can be effectively reduced, thereby reducing the fundamental frequency resonance noise between the damped part and the damping pad. Moreover, the groove is an annular structure, so that the groove is evenly distributed on the damping pad. If the grooves on the circumference of the damping pad are unevenly distributed, the structural strength of the damping pad at various locations along the circumference will be different. When the damping pad is subjected to force, the deformation at various locations along the circumference will be different, which will easily reduce the damping effect of the damping pad. Therefore, the grooves are distributed along the circumference of the damping pad, which can ensure the damping effect of the damping pad on the damped part, and is conducive to improving the user's use of the electrical appliance equipped with the damping pad.

[0012] In some technical schemes, optionally, the mounting end face includes a first end face and a second end face, the first end face and the second end face are two end faces in the shock-absorbing pad body that are opposite to each other; the groove includes a first groove and a second groove, the first groove is arranged on the first end face, and the second groove is arranged on the second end face.

[0013] The shock-absorbing pad is usually installed between two groups of parts to be shock-absorbed, wherein one of the parts to be shock-absorbed contacts the first end surface, and the other part to be shock-absorbed contacts the second end surface. A first groove is provided on the first end surface, thereby reducing the contact area between one of the parts to be shock-absorbed and the shock-absorbing pad, and a second groove is provided on the second end surface, thereby reducing the contact area between the other part to be shock-absorbed and the shock-absorbing pad. In the above manner, the contact area between the two groups of parts to be shock-absorbed and the shock-absorbing pad is reduced, which is conducive to further reducing the fundamental frequency resonance noise.

[0014] In some technical solutions, optionally, a positioning hole is provided on the shock-absorbing pad body, and the positioning hole is used for the positioning piece to pass through; the shock-absorbing foot pad also includes: a shock-absorbing protrusion, which is provided on the inner wall of the positioning hole, the shock-absorbing protrusion is distributed along the circumference of the positioning hole, and the shock-absorbing protrusion is used to contact the positioning piece.

[0015] In order to prevent the shock-absorbing pad body from moving in the installation position, it is necessary to position the shock-absorbing pad body. Specifically, a positioning hole is opened on the shock-absorbing pad body, and a positioning piece can be passed through the positioning hole. After the positioning piece is fixed, the positioning piece limits the shock-absorbing pad body to prevent the shock-absorbing pad body from moving in the installation position, thereby ensuring the installation stability of the shock-absorbing pad body and ensuring that the shock-absorbing pad body can stably absorb shock to the shock-absorbing part.

[0016] A shock absorbing protrusion is provided on the inner wall of the positioning hole. When the positioning piece is inserted into the positioning hole, the positioning piece contacts the shock absorbing protrusion, that is, the positioning piece does not need to contact the inner wall of the positioning hole, thereby reducing the contact area between the inner wall of the positioning hole and the positioning piece.

[0017] The positioning part needs to be installed on the part to be shock-absorbed. The vibration of the part to be shock-absorbed will be transmitted to the positioning part. By reducing the contact area between the inner wall of the positioning hole and the positioning part, it is helpful to reduce the fundamental frequency resonance noise between the positioning part and the shock-absorbing pad. The shock-absorbing pad can effectively absorb the vibration, further reduce the noise during the operation of the appliance, and enhance the user experience.

[0018] In some technical solutions, optionally, the thickness W of the shock-absorbing protrusion satisfies, 1mm≤W≤1.5mm.

[0019] When the thickness of the shock-absorbing protrusion is too large, the contact area between the shock-absorbing protrusion and the positioning piece is large, and the fundamental frequency resonance problem is likely to occur between the positioning piece and the shock-absorbing protrusion. When the thickness of the shock-absorbing protrusion is too small, the shock-absorbing protrusion cannot effectively support the positioning piece, causing the shock-absorbing foot pad to easily move. When the thickness of the shock-absorbing protrusion is set between 1mm and 1.5mm, the thickness of the shock-absorbing protrusion is sufficient to effectively support the positioning piece, and the positioning piece plays an effective shock-absorbing role on the shock-absorbing foot pad, preventing the shock-absorbing foot pad from moving. Moreover, the thickness of the shock-absorbing protrusion will not be too large, thereby avoiding a large contact area between the shock-absorbing protrusion and the positioning piece, and avoiding the fundamental frequency resonance problem between the positioning piece and the shock-absorbing protrusion.

[0020] In some technical solutions, optionally, one side of the shock-absorbing protrusion is connected to the inner wall of the positioning hole, and the other side of the shock-absorbing protrusion is provided with a chamfer.

[0021] If the contact area between the shock-absorbing protrusion and the positioning piece is large, the fundamental frequency resonance problem is likely to occur between the positioning piece and the shock-absorbing protrusion. If the thickness of the shock-absorbing protrusion is simply reduced, the shock-absorbing protrusion cannot effectively support the positioning piece, causing the shock-absorbing foot pad to easily move. A chamfer is set on the side of the shock-absorbing protrusion facing the positioning piece. Compared with the case where no chamfer is set on the positioning piece, when the chamfer contacts the positioning piece, there is a smaller contact area between the shock-absorbing protrusion and the positioning piece. The positioning piece has an effective shock-absorbing effect on the shock-absorbing foot pad, preventing the shock-absorbing foot pad from moving. Moreover, through the above method, there is no need to reduce the thickness of the positioning piece, thereby ensuring that the thickness of the shock-absorbing protrusion is sufficient to effectively support the positioning piece, and the positioning piece has an effective shock-absorbing effect on the shock-absorbing foot pad.

[0022] In some technical solutions, optionally, the shock-absorbing foot pad also includes: a mounting portion, connected to the shock-absorbing pad body, the mounting portion is used for mounting the shock-absorbing component, a limiting portion is provided at one end of the mounting portion away from the shock-absorbing pad body, the limiting portion protrudes from the side wall of the mounting portion, and the limiting portion is used to limit the shock-absorbing component from being separated from the mounting portion.

[0023] When the shock-absorbing member is mounted on the shock-absorbing foot pad, a part of the shock-absorbing member is sleeved on the mounting portion, and a sleeved relationship exists between the shock-absorbing member and the shock-absorbing foot pad, which can prevent the shock-absorbing member from being separated from the shock-absorbing foot pad. A limiting portion is provided on the mounting portion, and the limiting portion and the shock-absorbing member are engaged with each other, further improving the connection stability between the shock-absorbing foot pad and the shock-absorbing member.

[0024] In some technical solutions, optionally, the positioning hole includes a first positioning hole and a second positioning hole, the opening area of ​​the second positioning hole is larger than the opening area of ​​the first positioning hole, and the second positioning hole is arranged on a side of the shock absorbing pad body away from the mounting portion.

[0025] The opening area of ​​the first positioning hole is smaller, and the opening area of ​​the second positioning hole is larger, and the positioning piece can be inserted into the first positioning hole. Since the opening area of ​​the second positioning hole is larger, the structure of the shock-absorbing foot pad near the second positioning hole is more likely to deform, that is, the structure of the shock-absorbing foot pad is "softer", which is conducive to improving the shock-absorbing effect of the shock-absorbing foot pad.

[0026] In the second aspect, the utility model proposes a refrigeration device, including: a part to be damped, the part to be damped includes a compressor and a refrigeration device housing; a damping pad like the first aspect, the damping pad is located between the compressor and the refrigeration device housing, and the compressor and the refrigeration device housing are in contact with the installation end surface.

[0027] The compressor generates noise when it is running. By providing a shock-absorbing pad between the compressor and the housing of the refrigeration equipment, the vibration of the compressor can be prevented from being transmitted to the housing of the refrigeration equipment, thereby reducing the noise during the operation of the refrigeration equipment.

[0028] The shock-absorbing pad body has a mounting end face, and the compressor and the refrigeration equipment shell are fitted with different mounting end faces on the shock-absorbing pad body. A groove is arranged on the mounting end face, and the compressor and the groove are arranged opposite to each other, and the refrigeration equipment shell and the groove are arranged opposite to each other, thereby reducing the contact area between the compressor and the shock-absorbing pad, and reducing the contact area between the refrigeration equipment shell and the shock-absorbing pad, which is beneficial to reducing the fundamental frequency resonance noise between the compressor and the refrigeration equipment shell and the shock-absorbing pad. The shock-absorbing pad can effectively absorb vibration, prevent resonance between the compressor and the refrigeration equipment shell and the shock-absorbing pad, reduce the noise during operation of the refrigeration equipment, and help improve the user experience.

[0029] In some technical solutions, optionally, the refrigeration equipment also includes: a sleeve, the sleeve is inserted into the positioning hole of the shock-absorbing foot pad, the sleeve is in contact with the shock-absorbing protrusion of the shock-absorbing foot pad; a locking piece is passed through the sleeve, and the locking piece locks the sleeve to the refrigeration equipment housing.

[0030] The sleeve is inserted into the positioning hole, the locking piece passes through the sleeve and is locked on the refrigeration equipment housing, the locking piece limits the sleeve, and the sleeve limits the shock-absorbing pad to prevent the shock-absorbing pad from moving. When the locking piece is connected to the refrigeration equipment housing, the locking piece may rotate. If the locking piece is directly inserted into the positioning hole, the rotating locking piece may scratch the shock-absorbing pad. Therefore, the locking piece is covered with a sleeve to prevent the locking piece from directly contacting the shock-absorbing pad.

[0031] When the sleeve is inserted into the positioning hole, the positioning piece contacts the shock-absorbing protrusion, that is, the sleeve does not need to contact the inner wall of the positioning hole, thereby reducing the contact area between the inner wall of the positioning hole and the sleeve. By reducing the contact area between the inner wall of the positioning hole and the sleeve, it is helpful to reduce the fundamental frequency resonance noise between the sleeve and the shock-absorbing foot pad. The shock-absorbing foot pad can effectively absorb vibration, further reduce the noise when the appliance is running, and improve the user experience.

[0032] In some technical solutions, optionally, the first end of the sleeve extends out of a side of the shock-absorbing foot pad that is away from the refrigeration device housing, and the locking member abuts against the first end of the sleeve.

[0033] The first end of the sleeve is higher than the shock-absorbing foot pad, and the end of the locking member abuts against the first end of the sleeve, so that the sleeve is not easily separated from the refrigeration equipment housing. The sleeve limits the end of the locking member so that the end of the locking member does not contact the shock-absorbing foot pad, thereby preventing the locking member from damaging the shock-absorbing foot pad, ensuring the structural integrity of the shock-absorbing foot pad, and allowing the shock-absorbing foot pad to stably achieve shock absorption.

DETAILED DESCRIPTION

[0044] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0046] Refer to the following Figures 1 to 6 The invention describes a shock-absorbing foot pad and a refrigeration device provided according to some embodiments of the invention.

[0047] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in an embodiment of the utility model, a shock-absorbing foot pad 100 is proposed, including: a shock-absorbing pad body 110, a mounting end surface 120 on the shock-absorbing pad body 110 is used to contact the part to be shock-absorbed 200, and a groove 130 is provided on the mounting end surface 120, and the groove 130 is used to be arranged relative to the part to be shock-absorbed 200.

[0048] The shock-absorbing foot pad 100 provided in this embodiment is used to be installed on the part 200 to be shock-absorbed. Specifically, the shock-absorbing foot pad 100 is usually arranged between two groups of parts 200 to be shock-absorbed. The shock-absorbing foot pad 100 is used to absorb the vibration of the part 200 to be shock-absorbed, thereby avoiding noise generated due to vibration between the two groups of parts 200 to be shock-absorbed.

[0049] When the operating frequency of the shock-absorbing member 200 to be damped is close to the natural frequency of the shock-absorbing foot pad 100, the shock-absorbing effect of the shock-absorbing foot pad 100 is poor. At this time, the shock-absorbing foot pad 100 is easy to transmit vibration. However, the contact area between the shock-absorbing foot pad 100 and the shock-absorbing member 200 to be damped will affect the resonance noise. Therefore, by changing the contact area between the shock-absorbing foot pad 100 and the shock-absorbing member 200 to be damped, the resonance noise can be weakened.

[0050] Specifically, the shock-absorbing pad body 110 has an installation end surface 120. When the shock-absorbing pad body 110 and the part to be shock-absorbed 200 are installed, the part to be shock-absorbed 200 fits with the installation end surface 120 on the shock-absorbing pad body 110, and a groove 130 is provided on the installation end surface 120, and the groove 130 is arranged opposite to the part to be shock-absorbed 200, that is, at the position where the groove 130 is provided on the installation end surface 120, there is a gap between the part to be shock-absorbed 200 and the shock-absorbing foot pad 100. Therefore, without changing the shape and size of the shock-absorbing foot pad 100, the contact area between the part to be shock-absorbed 200 and the shock-absorbing foot pad 100 is reduced, which is beneficial to reducing the fundamental frequency resonance noise between the part to be shock-absorbed 200 and the shock-absorbing foot pad 100. The shock-absorbing foot pad 100 can effectively absorb vibration, prevent resonance of the two groups of parts to be shock-absorbed 200 installed on the shock-absorbing foot pad 100, reduce noise during operation of the electrical appliance, and help improve the user experience.

[0051] Moreover, by making grooves on the installation end surface 120 , there is no need to make major changes to the shape and size of the shock-absorbing foot pad 100 , which helps to reduce the difficulty of processing the shock-absorbing foot pad 100 .

[0052] Comparing the shock-absorbing foot pad 100 in this embodiment with the existing foot pads, when the contact area between the shock-absorbing foot pad 100 and the metal component is reduced, the axial stiffness and tangential stiffness of the shock-absorbing foot pad 100 are reduced, so the shock-absorbing foot pad 100 in this embodiment has a better improvement effect.

[0053] Exemplarily, the material of the shock-absorbing foot pad 100 is rubber.

[0054] like Figure 3 As shown, in some embodiments, optionally, the groove 130 includes an annular groove, and the annular groove is distributed along the circumference of the mounting end surface 120 .

[0055] A groove 130 is provided in the circumferential direction of the mounting end surface 120. By increasing the area of ​​the groove, the contact area between the damping member 200 to be damped and the damping pad 100 can be effectively reduced, thereby reducing the fundamental frequency resonance noise between the damping member 200 to be damped and the damping pad 100. Moreover, the groove 130 is in an annular structure, so that the groove 130 is evenly distributed on the damping pad 100. If the groove 130 in the circumferential direction of the damping pad 100 is unevenly distributed, the structural strength of the damping pad 100 at various locations in the circumferential direction will be different. When the damping pad 100 is subjected to force, the deformation at various locations in the circumferential direction will be different, which will easily reduce the damping effect of the damping pad 100. Therefore, the groove 130 is distributed in the circumferential direction of the damping pad 100, so as to ensure the damping effect of the damping pad 100 on the damping member 200 to be damped, which is conducive to improving the user's use effect of the electrical appliance equipped with the damping pad 100.

[0056] like Figure 3 As shown, in some embodiments, optionally, the mounting end surface 120 includes a first end surface 121 and a second end surface 122, and the first end surface 121 and the second end surface 122 are two end surfaces that are separated from each other in the shock absorbing pad body 110. The groove 130 includes a first groove 131 and a second groove 132, and the first groove 131 is provided on the first end surface 121, and the second groove 132 is provided on the second end surface 122.

[0057] The shock-absorbing foot pad 100 is usually installed between two groups of shock-absorbing parts 200, wherein one of the shock-absorbing parts 200 is in contact with the first end surface 121, and the other shock-absorbing part 200 is in contact with the second end surface 122. A first groove 131 is provided on the first end surface 121, thereby reducing the contact area between one of the shock-absorbing parts 200 and the shock-absorbing foot pad 100, and a second groove 132 is provided on the second end surface 122, thereby reducing the contact area between the other shock-absorbing part 200 and the shock-absorbing foot pad 100. In the above manner, the contact area between the two groups of shock-absorbing parts 200 and the shock-absorbing foot pad 100 is reduced, which is conducive to further reducing the fundamental frequency resonance noise.

[0058] Combination Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, a positioning hole 140 is provided on the shock absorbing pad body 110, and the positioning hole 140 is used for the positioning member 300 to pass through. The shock absorbing foot pad 100 also includes: a shock absorbing protrusion 150, which is provided on the inner wall of the positioning hole 140, and the shock absorbing protrusion 150 is distributed along the circumference of the positioning hole 140, and the shock absorbing protrusion 150 is used to contact the positioning member 300.

[0059] In order to prevent the shock-absorbing pad body 110 from moving in the installation position, the shock-absorbing pad body 110 needs to be positioned. Specifically, a positioning hole 140 is opened on the shock-absorbing pad body 110, and a positioning member 300 can be used to pass through the positioning hole 140. After the positioning member 300 is fixed, the positioning member 300 limits the shock-absorbing pad body 110 to prevent the shock-absorbing pad body 110 from moving in the installation position, thereby ensuring the installation stability of the shock-absorbing pad body 110 and ensuring that the shock-absorbing pad body 110 can stably damp the shock absorbing member 200.

[0060] A shock-absorbing protrusion 150 is provided on the inner wall of the positioning hole 140. When the positioning member 300 is inserted into the positioning hole 140, the positioning member 300 contacts the shock-absorbing protrusion 150, that is, the positioning member 300 does not need to contact the inner wall of the positioning hole 140, thereby reducing the contact area between the inner wall of the positioning hole 140 and the positioning member 300.

[0061] The positioning member 300 needs to be installed on the shock-absorbing member 200. The vibration of the shock-absorbing member 200 will be transmitted to the positioning member 300. By reducing the contact area between the inner wall of the positioning hole 140 and the positioning member 300, it is beneficial to reduce the fundamental frequency resonance noise between the positioning member 300 and the shock-absorbing foot pad 100. The shock-absorbing foot pad 100 can effectively absorb the vibration, further reduce the noise during the operation of the electrical appliance, and enhance the user experience.

[0062] In a possible application, the shock absorbing protrusion 150 and the shock absorbing pad body 110 are an integrated structure.

[0063] like Figure 3 As shown, in some embodiments, optionally, the thickness W of the shock-absorbing protrusion 150 satisfies, 1 mm ≤ W ≤ 1.5 mm.

[0064] When the thickness of the shock-absorbing protrusion 150 is too large, the contact area between the shock-absorbing protrusion 150 and the positioning member 300 is large, and the fundamental frequency resonance problem is likely to occur between the positioning member 300 and the shock-absorbing protrusion 150. When the thickness of the shock-absorbing protrusion 150 is too small, the shock-absorbing protrusion 150 cannot effectively support the positioning member 300, causing the shock-absorbing foot pad 100 to easily move. When the thickness of the shock-absorbing protrusion 150 is set between 1 mm and 1.5 mm, the thickness of the shock-absorbing protrusion 150 is sufficient to effectively support the positioning member 300, and the positioning member 300 plays an effective shock-absorbing role on the shock-absorbing foot pad 100, preventing the shock-absorbing foot pad 100 from moving. Moreover, the thickness of the shock-absorbing protrusion 150 is not too large, thereby avoiding a large contact area between the shock-absorbing protrusion 150 and the positioning member 300, and avoiding the fundamental frequency resonance problem between the positioning member 300 and the shock-absorbing protrusion 150.

[0065] Exemplarily, the thickness W of the shock-absorbing protrusion 150 is 1 mm, 1.2 mm or 1.5 mm.

[0066] like Figure 3 As shown, in some embodiments, optionally, one side of the shock-absorbing protrusion 150 is connected to the inner wall of the positioning hole 140 , and the other side of the shock-absorbing protrusion 150 is provided with a chamfer 160 .

[0067] If the contact area between the shock-absorbing protrusion 150 and the positioning member 300 is large, fundamental frequency resonance is likely to occur between the positioning member 300 and the shock-absorbing protrusion 150. If the thickness of the shock-absorbing protrusion 150 is simply reduced, the shock-absorbing protrusion 150 cannot effectively support the positioning member 300, causing the shock-absorbing foot pad 100 to easily move. A chamfer 160 is provided on the side of the shock-absorbing protrusion 150 facing the positioning member 300. Compared with the case where the chamfer 160 is not provided on the positioning member 300, when the chamfer 160 contacts the positioning member 300, there is a smaller contact area between the shock-absorbing protrusion 150 and the positioning member 300. The positioning member 300 has an effective shock-absorbing effect on the shock-absorbing foot pad 100, thereby preventing the shock-absorbing foot pad 100 from moving. Moreover, through the above method, there is no need to reduce the thickness of the positioning member 300, thereby ensuring that the thickness of the shock-absorbing protrusion 150 is sufficient to effectively support the positioning member 300, and the positioning member 300 has an effective shock-absorbing effect on the shock-absorbing foot pad 100.

[0068] Combination Figure 1 and Figure 3 As shown, in some embodiments, optionally, the shock-absorbing foot pad 100 also includes: a mounting portion 170, the mounting portion 170 is connected to the shock-absorbing pad body 110, the mounting portion 170 is used for mounting the shock-absorbing member 200, and a limiting portion 180 is provided at one end of the mounting portion 170 that is away from the shock-absorbing pad body 110, the limiting portion 180 protrudes from the side wall of the mounting portion 170, and the limiting portion 180 is used to limit the shock-absorbing member 200 from being separated from the mounting portion 170.

[0069] When the shock-absorbing member 200 is mounted on the shock-absorbing foot pad 100, a portion of the shock-absorbing member 200 is sleeved on the mounting portion 170, and there is a sleeved relationship between the shock-absorbing member 200 and the shock-absorbing foot pad 100, which can prevent the shock-absorbing member 200 from being separated from the shock-absorbing foot pad 100. A limiting portion 180 is provided on the mounting portion 170, and the limiting portion 180 and the shock-absorbing member 200 are mutually engaged, further improving the connection stability between the shock-absorbing foot pad 100 and the shock-absorbing member 200.

[0070] In a possible application, the shock absorbing pad body 110 , the mounting portion 170 and the limiting portion 180 are an integrated structure.

[0071] like Figure 3 As shown, in some embodiments, optionally, the positioning hole 140 includes a first positioning hole 141 and a second positioning hole 142, the opening area of ​​the second positioning hole 142 is larger than the opening area of ​​the first positioning hole 141, and the second positioning hole 142 is arranged on the side of the shock absorbing pad body 110 away from the mounting portion 170.

[0072] The opening area of ​​the first positioning hole 141 is relatively small, while the opening area of ​​the second positioning hole 142 is relatively large, and the positioning member 300 can be inserted into the first positioning hole 141. Since the opening area of ​​the second positioning hole 142 is relatively large, the structure of the shock-absorbing foot pad 100 near the second positioning hole 142 is more likely to deform, that is, the structure of the shock-absorbing foot pad 100 is more "soft", which is conducive to improving the shock-absorbing effect of the shock-absorbing foot pad 100.

[0073] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in an embodiment of the utility model, a refrigeration device is proposed, including: a shock-absorbing component 200 and a shock-absorbing foot pad 100 in any of the above embodiments, the shock-absorbing component 200 includes a compressor 210 and a refrigeration device housing 220, the shock-absorbing foot pad 100 is located between the compressor 210 and the refrigeration device housing 220, and the compressor 210 and the refrigeration device housing 220 are in contact with the installation end surface 120.

[0074] The compressor 210 generates noise when in operation. A shock-absorbing pad 100 is provided between the compressor 210 and the refrigeration device housing 220 to prevent the vibration of the compressor 210 from being transmitted to the refrigeration device housing 220, thereby reducing the noise during operation of the refrigeration device.

[0075] The shock-absorbing pad body 110 has an installation end surface 120, and the compressor 210 and the refrigeration equipment housing 220 are fitted with different installation end surfaces 120 on the shock-absorbing pad body 110. A groove 130 is arranged on the installation end surface 120, and the compressor 210 and the groove 130 are arranged relative to each other, and the refrigeration equipment housing 220 and the groove 130 are arranged relative to each other, thereby reducing the contact area between the compressor 210 and the shock-absorbing foot pad 100, and reducing the contact area between the refrigeration equipment housing 220 and the shock-absorbing foot pad 100, which is beneficial to reducing the fundamental frequency resonance noise between the compressor 210 and the refrigeration equipment housing 220 and the shock-absorbing foot pad 100. The shock-absorbing foot pad 100 can effectively absorb vibration, prevent the compressor 210 and the refrigeration equipment housing 220 from resonating with the shock-absorbing foot pad 100, reduce the noise during the operation of the refrigeration equipment, and help improve the user experience.

[0076] A mounting hole is provided on the foot of the compressor 210 , and the mounting hole is sleeved on the mounting portion 170 . The limiting portion 180 limits the foot so that the bottom plate is not easily separated from the shock-absorbing foot pad 100 .

[0077] Illustratively, the refrigeration device may be a refrigerator or a freezer, etc.

[0078] Combination Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, the refrigeration device further includes: a sleeve 310 and a locking piece 320, the sleeve 310 is inserted into the positioning hole 140 of the shock-absorbing foot pad 100, the sleeve 310 is in contact with the shock-absorbing protrusion 150 of the shock-absorbing foot pad 100, the locking piece 320 is passed through the sleeve 310, and the locking piece 320 locks the sleeve 310 to the refrigeration device housing 220.

[0079] The positioning member 300 includes a sleeve 310 and a locking member 320. The sleeve 310 is inserted into the positioning hole 140. The locking member 320 passes through the sleeve 310 and is locked on the refrigeration equipment housing 220. The locking member 320 limits the sleeve 310. The sleeve 310 limits the shock-absorbing foot pad 100 to prevent the shock-absorbing foot pad 100 from moving. When the locking member 320 is connected to the refrigeration equipment housing 220, the locking member 320 may rotate. If the locking member 320 is directly inserted into the positioning hole 140, the rotating locking member 320 may scratch the shock-absorbing foot pad 100. Therefore, the sleeve 310 is used to cover the locking member 320 to prevent the locking member 320 from directly contacting the shock-absorbing foot pad 100.

[0080] When the sleeve 310 is inserted into the positioning hole 140, the positioning member 300 contacts the shock-absorbing protrusion 150, that is, the sleeve 310 does not need to contact the inner wall of the positioning hole 140, thereby reducing the contact area between the inner wall of the positioning hole 140 and the sleeve 310. By reducing the contact area between the inner wall of the positioning hole 140 and the sleeve 310, it is helpful to reduce the fundamental frequency resonance noise between the sleeve 310 and the shock-absorbing foot pad 100, and the shock-absorbing foot pad 100 can effectively absorb vibration, further reduce the noise when the electrical appliance is running, and improve the user experience.

[0081] In some embodiments, optionally, the first end of the sleeve 310 extends out of a side of the shock-absorbing foot pad 100 away from the refrigeration equipment housing 220 , and the locking member 320 abuts against the first end of the sleeve 310 .

[0082] The first end of the sleeve 310 is higher than the shock-absorbing foot pad 100, and the end of the locking member 320 abuts against the first end of the sleeve 310, so that the sleeve 310 is not easily separated from the refrigeration equipment housing 220. The sleeve 310 limits the end of the locking member 320, so that the end of the locking member 320 does not contact the shock-absorbing foot pad 100, thereby preventing the locking member 320 from causing damage to the shock-absorbing foot pad 100, ensuring the structural integrity of the shock-absorbing foot pad 100, and allowing the shock-absorbing foot pad 100 to stably achieve shock absorption.

[0083] The compressor 210 is placed on the shock-absorbing foot pad 100 through the base. There is a metal cylinder in the internal positioning hole 140 of the shock-absorbing foot pad 100, which is called a bushing, that is, the above-mentioned sleeve 310. Screws are placed in the bushing, that is, the above-mentioned locking member 320. The screws fix the shock-absorbing foot pad 100 on the bottom plate of the refrigeration equipment for four-point positioning. The thickness of the positioning hole 140 affects the contact area between the shock-absorbing foot pad 100 and the bushing. If the area is too large, the fundamental frequency resonance noise during the operation of the refrigeration equipment will be large. If the area is too small, the bushing will be installed unstably. After the compressor 210 is fixed to the shock-absorbing foot pad 100, it should be ensured that the screw and the shock-absorbing foot pad 100 do not contact each other, that is, when the screw is tightened, the lower end of the screw head will not squeeze the shock-absorbing foot pad 100, thereby causing the shock-absorbing foot pad 100 to deform and fail. In this installation state, the compressor 210 will not have direct contact with the metal screw, and the screw only plays a positioning role in the horizontal direction and will not produce constraints in the vertical direction.
