Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a base pad, packaging component and refrigeration equipment. Background Technology

[0002] With the development of the home appliance manufacturing industry, refrigeration equipment, as an indispensable part of the home, is constantly being designed and manufactured to meet users' needs for functionality and aesthetics. Refrigeration equipment is usually equipped with several feet, which not only support the weight of the entire refrigeration equipment but also allow users to adjust the height of the refrigeration equipment to ensure horizontal placement and adapt to different ground conditions.

[0003] In traditional refrigeration equipment transportation, recesses are often designed into the base of the refrigeration equipment to accommodate its legs, facilitating installation. However, this design presents some problems in practical applications.

[0004] Specifically, due to the need to consider operating space during installation, the size of the recess is often much larger than the actual size of the support legs. This results in wasted internal space in the base, reducing the overall space utilization of the refrigeration equipment. Furthermore, there is a gap between the recess and the support legs, lacking effective filling material. During the use of the refrigeration equipment, noise and vibration are generated due to the operation of the internal refrigeration system and the influence of the external environment. This noise and vibration not only affect the user experience but may also damage the refrigeration equipment. Utility Model Content

[0005] The main purpose of this invention is to provide a base pad, packaging component, and refrigeration equipment that can improve space utilization and shock absorption.

[0006] To achieve the above objectives, an embodiment of the first aspect of this utility model provides a base pad, comprising:

[0007] The base pad body has an upward-facing recessed cavity, which is at least used to accommodate the support legs of the refrigeration equipment;

[0008] A buffer pad is provided in the cavity, and the buffer pad extends at least partially out of the cavity and is used to support the bottom beam of the refrigeration equipment.

[0009] In some embodiments, the base pad body includes an inner region and an outer peripheral region. The outer peripheral region is connected to the outer periphery of the inner region and surrounds the inner region. The outer peripheral region has a plurality of cavities, and each cavity is arranged circumferentially around the inner region. Each cavity contains at least one buffer pad.

[0010] In some embodiments, the base body includes four sidewalls connected in sequence to form four included angles, and a cavity is provided at the included angle, the cavity being adapted to accommodate each leg of the refrigeration equipment.

[0011] In some embodiments, the cushioning pad includes a relief groove that is recessed toward an inward region to accommodate the foot.

[0012] In some embodiments, the interior region has a through hole that extends through the base body along the concave direction of the cavity.

[0013] In some embodiments, the base pad includes a support protrusion connected to the base pad body. The support protrusion protrudes vertically from the base pad body and is adapted to abut against the lower side of the door of the refrigeration equipment.

[0014] In some embodiments, the bottom pad includes a plurality of support protrusions, which are spaced apart along a first direction, the first direction being perpendicular to the recess direction of the cavity;

[0015] The supporting protrusion includes a protrusion body and a wedge-shaped rib. The wedge-shaped rib is connected to the protrusion body and protrudes from the protrusion body in a first direction. In the vertical direction, the distance from the side of the wedge-shaped rib closer to the base pad body to the protrusion body is greater than the distance from the side of the wedge-shaped rib farther from the base pad body to the protrusion body.

[0016] In some embodiments, the base pad includes a clearance portion connected to the base pad body. The clearance portion is located in the inner region on the side opposite to the support protrusion. The clearance portion protrudes vertically and is adapted to abut against the compressor base plate of the refrigeration equipment.

[0017] In the vertical direction, the height of the clearance section is less than that of the supporting protrusion.

[0018] In some embodiments, the base pad body includes an inner ring protrusion and an outer ring protrusion, which protrude in the same direction. The inner ring protrusion surrounds the inner region circumferentially, and the outer ring protrusion surrounds the outer region circumferentially. The inner ring protrusion and the outer ring protrusion are spaced apart. The inner ring protrusion is provided with an inner ring reinforcing rib, which protrudes in a direction perpendicular to the protrusion of the inner ring protrusion and is connected to the base pad body. The outer ring protrusion is provided with an inner ring reinforcing rib, which protrudes in a direction perpendicular to the protrusion of the outer ring protrusion and is connected to the base pad body.

[0019] A second aspect of this utility model provides a packaging component including the base pad of any of the above embodiments.

[0020] A third aspect of this utility model provides a refrigeration device, including the packaging components of any of the above embodiments, and the refrigeration device further includes a refrigeration body for cooling a target object.

[0021] According to the above embodiments, the beneficial effects of this utility model are:

[0022] An embodiment of the first aspect of this utility model provides a base pad for supporting refrigeration equipment. The base pad includes a base pad body and a cushioning pad. The base pad body is the core component of the base pad and has an upward-facing cavity. The cavity is designed to accommodate at least the legs of the refrigeration equipment to ensure the stability of the refrigeration equipment during transportation or storage. By placing the legs of the refrigeration equipment within the cavity, unnecessary movement of the refrigeration equipment can be effectively prevented.

[0023] A buffer pad is placed inside the recessed cavity. This buffer pad forms a soft contact surface between the refrigeration equipment and the base pad, effectively preventing damage that could be caused by direct collisions between the two. The buffer pad extends at least partially beyond the recessed cavity; that is, the upper surface of the buffer pad is higher than the opening edge of the cavity. This design ensures direct contact with the base beam supporting the refrigeration equipment and increases the contact area with the base beam, thus improving the overall structural stability.

[0024] Furthermore, this application places the buffer pad within the recess, which can make reasonable use of the space that would otherwise be wasted within the recess. Specifically, the base pad needs a recess to avoid the support legs of the refrigeration equipment. To facilitate the installation of the refrigeration equipment, the recess needs to be significantly larger than the support legs to improve the assembly efficiency of the refrigeration equipment and the base pad. Therefore, there is excess space in the recess, meaning that the space utilization rate of the recess is not high. The buffer pad of this application is placed within the recess of the base pad body used to accommodate the support legs. This allows the buffer pad to make reasonable use of the excess space within the recess, eliminating the need for additional slots to accommodate the buffer pad, thereby reducing the size of the slots in the base pad body and improving the structural strength of the base pad body.

[0025] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0045] Reference Figures 1 to 11 The first aspect of this utility model provides a base pad for supporting refrigeration equipment. The base pad includes a base pad body 100 and a buffer pad 200. (See also...) Figure 1 and Figure 2 The base pad body 100 is the core component of the base pad. The base pad body 100 has an upward-facing recess 121, which is used to accommodate at least the support legs of the refrigeration equipment to ensure that the refrigeration equipment remains stable during transportation or storage. By placing the support legs of the refrigeration equipment in the recess 121, unnecessary movement of the refrigeration equipment can be effectively prevented.

[0046] Reference Figure 1 and Figure 2 A buffer pad 200 is disposed within the recess 121. The buffer pad 200 forms a soft contact surface between the refrigeration equipment and the base pad, effectively preventing damage that may be caused by direct collision between the refrigeration equipment and the base pad. The buffer pad 200 extends at least partially out of the recess 121, meaning that the height of the upper surface of the buffer pad 200 is higher than the height of the opening edge of the recess 121. This design ensures direct contact with the base beam supporting the refrigeration equipment and increases the contact area with the base beam, thereby improving the overall structural stability.

[0047] Furthermore, referring to Figure 1In this application, the buffer pad 200 is disposed within the cavity 121, which can make reasonable use of the space that would otherwise be wasted within the cavity 121. Specifically, the base pad needs to have a cavity 121 to avoid the support legs of the refrigeration equipment. To facilitate the installation of the refrigeration equipment, the cavity 121 needs to be significantly larger than the size of the support legs to improve the assembly efficiency of the refrigeration equipment and the base pad. Therefore, there is excess space in the cavity 121, meaning that the space utilization rate of the cavity 121 is not high. The buffer pad 200 of this application is disposed within the cavity 121 of the base pad body 100 for accommodating the support legs. This allows the buffer pad 200 to make reasonable use of the excess space within the cavity 121, eliminating the need for additional slots to accommodate the buffer pad 200, thereby reducing the size of the slots in the base pad body 100 and improving the structural strength of the base pad body 100.

[0048] Furthermore, in some embodiments, the buffer pad 200 is made of an elastic material. When pressure is applied by the refrigeration equipment, the buffer pad 200 deforms to absorb impact energy and then returns to its original shape. This process ensures the stable placement of the refrigeration equipment and reduces the potential risk of damage due to vibration or impact.

[0049] Regarding the support legs, it should be noted that the support legs of the refrigeration equipment are the supporting structure of the refrigeration equipment itself. They can be protruding brackets or pads of the refrigeration equipment, wheels of the refrigeration equipment, or protruding structures used to install wheels of the refrigeration equipment.

[0050] Understandably, the separate design of the base pad body 100 and the cushioning pad 200 facilitates the configuration of the base pad body 100 and the cushioning pad 200 made of different materials. For example, the base pad body 100 can be made of hard plastic to prevent moisture and maintain structural rigidity, while the cushioning pad 200 can be made of a material with cushioning properties, such as honeycomb board or rubber sheet, to provide cushioning capacity for the base pad. With this design, the base pad not only has sufficient structural strength and moisture-proof effect, but also sufficient cushioning capacity to protect refrigeration equipment during transportation or use.

[0051] In some embodiments, the base pad body 100 has only one recess 121, which has a large area, and all or part of the support legs of the refrigeration equipment are located in this single recess 121. A buffer pad 200 is provided in the recess 121 to support the bottom beam of the refrigeration equipment.

[0052] In some embodiments, the base body 100 has a plurality of recesses 121, which may be spaced apart, and some or all of the recesses 121 may be configured to be interconnected. The recesses 121 may correspond one-to-one with each support leg of the refrigeration device, or only some may be used to accommodate the support legs of the refrigeration device, with the others empty. This design facilitates adaptation to various models of refrigeration devices.

[0053] In some embodiments, the accommodating space of the cavity 121 is larger than the volume of a single buffer pad 200, meaning the cavity 121 has surplus capacity. This design allows multiple buffer pads 200 to be stacked within the cavity 121 to adjust the level of cushioning. Furthermore, the ample space in the cavity 121 facilitates the assembly of the refrigeration equipment. The shape and size of the cavity 121 can be customized according to the actual specifications of the refrigeration equipment's legs, allowing the legs to be securely embedded within it. This structural design not only provides a stable support platform for the refrigeration equipment but also helps to distribute the pressure applied by the refrigeration equipment.

[0054] Reference Figure 1 and Figure 2 In some embodiments, the base pad body 100 includes an inner region 110 and an outer peripheral region 120. The outer peripheral region 120 is connected to the outer periphery of the inner region 110 and surrounds the inner region 110. The outer peripheral region 120 has a plurality of cavities 121, and each cavity 121 is arranged circumferentially around the inner region 110. Each cavity 121 contains at least one buffer pad 200 to support different legs of the refrigeration equipment. This multi-point support method not only enhances the overall stability of the base pad but also helps to evenly distribute the pressure from the refrigeration equipment and reduce the load borne by a single support point.

[0055] In some embodiments, the inner region 110 is configured as the core part of the base pad, primarily responsible for providing central support, while the outer peripheral region 120 focuses on edge reinforcement. Together, they form a support system that is both robust and flexible. By rationally planning the number and relative positions of the cavities 121, the needs of various specifications of refrigeration equipment can be met, improving the versatility and adaptability of the base pad. Furthermore, the outer peripheral region 120 surrounding the inner region 110 also provides additional protection, preventing external factors from affecting the internal structure.

[0056] It is understood that, in some embodiments, the number of cavities 121 in the outer peripheral region 120 can be appropriately increased or decreased according to the distribution of the cooling device's feet to ensure that each foot is effectively supported. In some embodiments, the material and thickness of the cushioning pad 200 can also be adjusted according to different application scenarios, such as choosing a thicker pad to enhance the shock absorption effect, or using a softer material to improve comfort. In some embodiments, considering ease of assembly, the outer contour of the base pad body 100 may be designed as circular, square, or other geometric shapes to better match the shape characteristics of the bottom of the cooling device. In some embodiments, to improve the grip of the base pad, an anti-slip texture or coating can be added to the surface of the outer peripheral region 120, so that the base pad will not easily slip even in wet and slippery environments.

[0057] Reference Figure 1 and Figure 2 In some embodiments, the base pad body 100 includes four sidewalls connected sequentially to form four included angles. A recess 121 is located at each included angle and is adapted to accommodate each leg of the refrigeration equipment. The bottom surface of the refrigeration equipment is typically square. In this embodiment, the base pad is designed as square, with the recesses 121 positioned at the four included angles of the square, each corresponding to one of the four legs of the refrigeration equipment. This layout ensures that each leg can find a specially designed recess 121 for placement, guaranteeing the stability and accuracy of the refrigeration equipment during placement. Furthermore, when the refrigeration equipment is subjected to vibration or tilt, the pressure generated by its legs is the greatest, and the stroke of movement is the largest. Aligning the recesses 121 with the legs allows the buffer pad 200 to be positioned at the bottom beam of the refrigeration equipment leg, thereby improving the shock absorption effect. In addition, the higher the matching degree between the recesses 121 and the legs, the more effectively the pressure applied to the base pad can be dispersed, reducing the risk of localized stress concentration.

[0058] In some embodiments, taking into account the complex environment that may be encountered during transportation, the outer surface of the sidewall may be specially treated, such as by adding anti-slip textures or coatings, to improve the grip of the base pad and prevent it from sliding during movement.

[0059] In some embodiments, the contour liquid of the base pad can be disc-shaped or other irregular shapes, as long as it has a cavity 121 corresponding to the support leg of the refrigeration equipment.

[0060] Reference Figure 1 and Figure 2 In some embodiments, the buffer pad 200 includes a relief groove 210 that is recessed toward the inner region 110 to accommodate the support legs. By accommodating the support legs of the refrigeration equipment, the relief groove 210 allows the refrigeration equipment to sink sufficiently so that the bottom beam of the refrigeration equipment abuts against the buffer pad 200, thereby achieving the shock absorption effect provided by the buffer pad 200.

[0061] In some embodiments, when the refrigeration unit is placed on the base pad, the legs first contact the cushioning pad 200 in the recess 121, and then, as the pressure continues, the legs gradually enter the clearance groove 210. The presence of the clearance groove 210 allows the legs more vertical movement, enabling the refrigeration unit to sink down until its base beam abuts against the cushioning tank pad.

[0062] Furthermore, in some embodiments, each buffer pad 200 is provided with a recessed relief groove 210 facing the inner region 110. The legs of the refrigeration equipment are all configured to be inserted vertically into the corresponding relief groove 210, and the diameter of the relief groove 210 matches the size of the leg. With this design, all the legs of the refrigeration equipment must be inserted vertically into the relief groove 210 to achieve stable assembly with the base pad. Moreover, since the diameter of the relief groove 210 matches the size of the leg, after the refrigeration equipment and the base pad are assembled, the multiple legs and relief grooves 210 restrict each other, and the legs cannot move freely in the horizontal direction relative to the base pad. That is, the refrigeration equipment can no longer move freely, thereby realizing the positioning of the refrigeration equipment by the base pad on the horizontal plane.

[0063] In some embodiments, the edges of the clearance groove 210 should be designed with a smooth transition to reduce scratch damage to the surface of the support leg.

[0064] Reference Figure 1 and Figure 2 In some embodiments, the inner region 110 has a through-hole 111 extending through the base pad body 100 along the recessed direction of the cavity 121. The presence of the through-hole 111 makes the base pad lighter, reducing material costs and weight, which is especially important for the packaging and handling of large household appliances such as refrigeration equipment. From a mechanical performance perspective, the through-hole 111 does not weaken the overall strength of the base pad because its location is in the inner region 110, away from the main stress point, i.e., the cavity 121 portion of the outer peripheral region 120. At the same time, through reasonable layout and size design, the through-hole 111 can also play an auxiliary positioning role, helping users accurately place the refrigeration equipment on the base pad and ensuring that the support legs are correctly aligned with the cavity 121.

[0065] Understandably, the through-hole 111 design also provides a direct path for air or liquid to flow freely, thereby reducing pressure differences that may occur due to temperature changes during transportation. This design helps maintain consistent environmental pressure inside and outside the mat, avoiding potential damage to the mat or refrigeration equipment caused by pressure imbalances.

[0066] It is understood that in some embodiments, the shape and size of the through-hole 111 can be adjusted according to actual needs. For example, a circle, square, or other polygons are all feasible choices, depending on the manufacturing process and whether it needs to be used with other components. To further optimize the function of the through-hole 111, reinforcing ribs can be added to the edges of the through-hole 111 to prevent crack propagation during use. In addition, considering environmental protection factors, the through-hole 111 can also serve as an entry point for disassembling the base pad during recycling, facilitating subsequent processing. The through-hole 111 can also be used to embed additional functional components, such as humidity sensors or tags, which can provide users with more convenience.

[0067] Reference Figures 3 to 7 In some embodiments, the base pad includes a support protrusion 130 connected to the base pad body 100. The support protrusion 130 protrudes vertically from the base pad body 100 and is adapted to abut against the lower side of the refrigeration equipment door. The main function of the support protrusion 130 is to provide additional support points when the refrigeration equipment is placed on the base pad, especially for such a critical area as the lower side of the door. It is understood that the support protrusion 130 is provided to prevent damage to the hinges and other rotating structures of the refrigeration equipment door due to torque, as the door's pivot point is vertical.

[0068] It is understood that in some embodiments, the number and distribution of the support protrusions 130 can be flexibly configured according to different styles of refrigeration equipment. For example, for double-door refrigeration equipment, one support protrusion 130 can be provided on each side of the door; while for French four-door or multi-door refrigeration equipment, the number of support protrusions 130 can be increased according to the door layout to ensure that each door receives adequate support. In addition, the material of the support protrusions 130 can be a material with a certain degree of elasticity, such as rubber or soft plastic, which can provide sufficient support while reducing hard impact on the surface of the refrigeration equipment. To enhance the anti-slip effect, the top surface of the support protrusions 130 can be designed with a texture or treated with a special coating to increase the friction between the support protrusions and the door of the refrigeration equipment and prevent the refrigeration equipment from shifting on the base.

[0069] Reference Figures 3 to 7 In some embodiments, the base pad includes a plurality of support protrusions 130, which are spaced apart along a first direction perpendicular to the recessed direction of the cavity 121. Each support protrusion 130 includes a protrusion body 131 and a wedge-shaped rib 132. The wedge-shaped rib 132 connects to the protrusion body 131 and protrudes from the protrusion body 131 along the first direction. Vertically, the distance from the side of the wedge-shaped rib 132 closest to the base pad body 100 to the protrusion body 131 is greater than the distance from the side of the wedge-shaped rib 132 furthest from the base pad body 100 to the protrusion body 131. Specifically, the support protrusions 130 are designed to provide effective support for the underside of the refrigeration equipment door while ensuring that excessive contact does not affect the opening and closing of the refrigeration equipment door. Each support protrusion 130 consists of two main parts: a protrusion body 131, which provides the basic height for contact with the refrigeration equipment door; and a wedge-shaped rib 132, whose special wedge design allows for the dispersion of pressure through a gradually increasing contact area when subjected to the weight of the refrigeration equipment, thereby protecting the refrigeration equipment door from damage caused by localized stress concentration. This structure also allows the support protrusion 130 a certain amount of deformation space under pressure, enhancing the overall cushioning performance of the base pad.

[0070] Furthermore, the multiple support protrusions 130 are connected by ribs, and the connection structure between the multiple support protrusions 130 and the ribs is H-shaped to ensure structural strength. The wedge-shaped rib 132 has a triangular outline, and its hypotenuse is opposite to the support protrusion 130 to further consolidate the structural strength of the support protrusion 130 and reduce deformation such as lateral bending of the support protrusion 130.

[0071] Reference Figures 1 to 3 In some embodiments, the base pad includes a clearance portion 140 connected to the base pad body 100. The clearance portion 140 is located on the side of the inner region 110 opposite to the support protrusion 130. The clearance portion 140 protrudes vertically and is adapted to abut against the compressor base plate of the refrigeration equipment. Specifically, the height of the clearance portion 140 is less than that of the support protrusion 130 in the vertical direction. The compressor base plate of the refrigeration equipment is used to support machines such as compressors. It is typically a thin metal plate, which is prone to dents or deformation under excessive pressure, leading to damage. The clearance portion 140 is designed with a height less than that of the support protrusion 130 in the vertical direction, so that the force exerted by the clearance portion 140 on the compressor base plate is smaller, or in some extreme cases, the clearance portion 140 may only support the compressor base plate of the refrigeration equipment to maintain the balance of the refrigeration equipment. The clearance portion 140 serves to protect the compressor base plate of the refrigeration equipment.

[0072] Reference Figures 1 to 3 In some embodiments, a rectangular array of small rectangular grids is used in the weight-concentrated areas of the press base plate to disperse the compressive and supporting forces. The outer edge of the base pad is reinforced with an asymmetrical structure 150 to enhance edge strength and reduce the height of the boss to create a buffer 140, preventing the press base plate from directly bearing the impact and deforming.

[0073] Understandably, to further protect the compressor base plate of the refrigeration equipment, the top of the clearance portion 140 can be designed as a flat surface with a large area. In this embodiment, the clearance portion 140 mainly serves as an auxiliary support, and its own stress is less than that of the support protrusion 130. Therefore, it is not necessary to design the support protrusion 130 as a highly stable structure. For example, the clearance portion 140 is a strip-shaped protrusion with a rectangular flat surface on its upper surface. Designing a clearance portion 140 with a large area to contact the compressor base plate of the refrigeration equipment can further prevent excessive local pressure on the clearance portion 140 from damaging the compressor base plate of the refrigeration equipment.

[0074] In some embodiments, the base pad body 100 includes an inner ring protrusion and an outer ring protrusion, which protrude in the same direction. The inner ring protrusion surrounds the inner region 110 circumferentially, and the outer ring protrusion surrounds the outer peripheral region 120 circumferentially. The inner ring protrusion and the outer ring protrusion are spaced apart. The inner ring protrusion is provided with an inner ring reinforcing rib, which protrudes in a direction perpendicular to the protrusion of the inner ring protrusion and connects to the base pad body 100. The outer ring protrusion is provided with an inner ring reinforcing rib, which protrudes in a direction perpendicular to the protrusion of the outer ring protrusion and connects to the base pad body 100. The inner ring protrusion and the outer ring protrusion are used to maintain the mechanical structure of the base pad. In some embodiments, the outer ring protrusion and the inner ring protrusion are both formed into a ring to prevent the base pad from twisting and deforming. The inner ring reinforcing rib is provided on the inner ring protrusion and protrudes in a direction perpendicular to the protrusion of the inner ring protrusion to prevent the inner ring protrusion from bending. The outer ring reinforcing rib is located on the outer ring protrusion and protrudes in a direction perpendicular to the outer ring protrusion to prevent the outer ring protrusion from bending.

[0075] In some embodiments, the inner ring protrusions alternately protrude in opposite directions, thus configuring the inner ring protrusion structure into an S-shape, further enhancing the stability of the inner ring protrusion structure and preventing bending or curling along the protrusion direction. Similarly, in some embodiments, the outer ring protrusions alternately protrude in opposite directions, thus configuring the outer ring protrusion structure into an S-shape, further enhancing the stability of the outer ring protrusion structure and preventing bending or curling along the protrusion direction.

[0076] In some embodiments, the hardness of the cushioning pad 200 is less than that of the base pad body 100. Specifically, the cushioning pad 200 is typically made of an elastic material, such as rubber or polyurethane foam, which can deform significantly under pressure, thus providing effective cushioning. The base pad body 100 is made of a relatively rigid material, such as high-density polyethylene (HDPE) or other engineering plastics, which provide the necessary structural strength and stability to ensure that the base pad as a whole is not easily deformed.

[0077] When the refrigeration equipment is placed on the base pad, its legs first contact the cushioning pad 200, and then gradually transfer the pressure to the base pad body 100. Because the cushioning pad 200 is relatively soft, it can compress itself appropriately without damaging the base beam of the refrigeration equipment, thereby absorbing and reducing the pressure from above. As the pressure continues to be transmitted, the base pad body 100 eventually bears the main load. The softness of the cushioning pad 200 allows it to be finely adjusted according to the shape of the legs, achieving a better fit and thus providing more precise support. At the same time, the lower hardness of the cushioning pad 200 can effectively isolate external vibrations, reducing potential noise problems during the operation of the refrigeration equipment. This design with varying hardness provides dual protection for the refrigeration equipment. On the one hand, the cushioning pad 200, through its softness and compressibility, directly protects the legs and base beam of the refrigeration equipment from damage by hard impacts; on the other hand, the higher hardness of the base pad body 100 ensures the stability and long-term reliability of the entire base pad structure. This combination not only improves the safety of the refrigeration equipment but also enhances the user experience. The extra protection provided by the cushioning pad 200 is especially important for refrigeration equipment that needs to be moved or transported frequently.

[0078] It is understandable that, in some embodiments, to optimize the cushioning effect, different hardness levels of the cushioning pad 200 material can be selected according to the actual application scenario. For example, in environments with greater vibration, a softer material can be selected to improve shock absorption performance; while in static environments, a slightly harder cushioning pad 200 may be more beneficial in keeping the refrigeration equipment in a fixed position.

[0079] In some embodiments, a multi-layered composite structure of the cushioning pad 200 can also be considered, where a very soft material is used as the first line of defense on the surface, and an intermediate layer with a certain degree of elasticity is embedded inside to achieve the best cushioning effect. For special-purpose refrigeration equipment, such as shock-resistant refrigeration equipment, the use of new materials such as memory foam can even be explored to enable the cushioning pad 200 to better adapt to complex working environments.

[0080] A second aspect of this utility model provides a packaging assembly including a base pad from any of the above embodiments. The packaging assembly is used to package refrigeration equipment to facilitate its transport. In some embodiments, the packaging assembly may further include a housing, which, after covering the refrigeration equipment, is assembled with the base pad. The housing may be made of foam material to provide shock absorption, further ensuring the shock absorption effect during the transport of the refrigeration equipment.

[0081] A third aspect of this utility model provides a refrigeration device, which includes the packaging components described in any of the above embodiments. The refrigeration device also includes a refrigeration body for cooling a target object. In some embodiments, the refrigeration device may be a wine cabinet, medicine cabinet, display cabinet, or refrigerator, etc. Placing the refrigeration device in the base pad of this application, the shock-absorbing structure of the base pad (i.e., other packaging components) can protect the refrigeration device during transportation and use. The base pad of this application makes reasonable use of the excess space within the cavity 121, resulting in a compact structure and high space utilization. Furthermore, the buffer pad 200 located in the cavity 121 can provide shock absorption and cushioning, thereby protecting the refrigeration device. In addition, the buffer pad 200 can also have clearance grooves 210, which correspond to the legs of the refrigeration body, enabling the positioning and efficient assembly of the refrigeration body and the base pad.

[0082] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
