Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electrical appliance packaging, and in particular to a packaging base pad. Background Art

[0002] In order to protect the electrical appliances during transportation, a packaging bottom pad is generally provided under the electrical appliances. In the related art, the bottom of the electrical appliances is usually provided with a foot, which is threadedly connected to the bottom of the electrical appliances. The packaging bottom pad is provided with an avoidance groove opposite to the foot, and the foot is located in the avoidance groove. However, during the transportation of the electrical appliances, the foot is easy to fall into the avoidance groove. Utility Model Content

[0003] The embodiment of the present application provides a packaging base pad, which can solve the technical problem that the base feet are easily dropped into the avoidance groove during the transportation of electrical appliances.

[0004] In a first aspect, an embodiment of the present application provides a packaging base pad, which is located under an electrical appliance, wherein the electrical appliance includes a mounting plate and a base foot located at the bottom thereof, wherein the base foot is threadedly connected to the mounting plate, and the packaging base pad is provided with an avoidance groove opposite to the base foot, wherein a support column is provided in the avoidance groove, and a distance between the top of the support column and the bottom surface of the mounting plate is less than a height of the base foot.

[0005] The packaging base pad of the embodiment of the present application, during the transportation of the refrigerator, when the base rotates relative to the box body and moves away from the box body, the lower end of the base can abut against the upper end of the support column, and the support column can block the base, so that the base can be connected to the hinge plate, and the base can be prevented from separating from the hinge plate and falling into the avoidance groove as much as possible. When the base continues to move away from the box body, the lower end of the base applies a greater abutting force to the upper end of the support column, and the support column is crushed, which can minimize the bending and deformation of the base.

[0006] In some possible embodiments of the present application, the cross-sectional area of ​​the support column decreases along the direction of the bottom of the avoidance groove pointing toward the electrical appliance.

[0007] By such arrangement, the strength of the support column can be gradually increased in the direction of the refrigerator pointing to the bottom of the avoidance groove. When the foot continues to move away from the box body, the support column can be gradually crushed, so that the support column still has a sufficient height after being crushed to block the foot, thereby preventing the foot from bending and deforming and separating from the box body as much as possible.

[0008] In some possible embodiments of the present application, the cross-sectional area of ​​the support column decreases continuously.

[0009] By such arrangement, the strength of the support column can be continuously increased in the direction of the refrigerator pointing to the bottom of the avoidance groove. When the foot continues to move away from the box body, the support column can be gradually crushed, so that the support column still has a sufficient height when crushed to block the foot, thereby preventing the foot from bending and deforming and separating from the box body as much as possible.

[0010] In some possible embodiments of the present application, the support column is a prism or a frustum.

[0011] Such an arrangement can make the center line of the prism or cone consistent with the moving direction of the base, and the position of the abutment force between the base and the crushed support column will not change significantly compared to before the support column was crushed, thereby maximizing the stability of the force position of the base and preventing the base from bending and deforming.

[0012] In some possible embodiments of the present application, the cross-sectional area of ​​the support column decreases in a step-by-step manner.

[0013] By such arrangement, the strength of the support column can be increased stepwise in the direction of the refrigerator pointing to the bottom of the avoidance groove. When the foot continues to move away from the box body, the support column can be gradually crushed, so that the support column still has a sufficient height when crushed to block the foot, thereby preventing the foot from bending and deforming and separating from the box body as much as possible.

[0014] In some possible embodiments of the present application, along the bottom of the avoidance groove pointing to the bottom of the appliance, the support column includes at least two supporting parts connected in sequence, the center lines of at least two of the supporting parts are collinear, and the cross-sectional areas of at least two supporting parts decrease in sequence.

[0015] With such an arrangement, since the center lines of at least two supporting parts are collinear, the position of the abutment force between the base foot and the crushed supporting column will not change significantly compared to before the supporting column was crushed, thereby maximizing the stability of the force position of the base foot and helping to prevent the base foot from bending and deforming.

[0016] In some possible embodiments of the present application, at least two support parts include a first support part and a second support part, the first support part is closer to the bottom of the avoidance groove than the second support part, the cross-sectional area of ​​the first support part is larger than the cross-sectional area of ​​the second support part, and the distance between the top of the first support part and the bottom of the electrical appliance is smaller than the height of the base foot.

[0017] With such an arrangement, there can be two support parts, and the support columns comprising the two support parts can effectively prevent the base from separating from the box body and prevent the base from bending and deforming. At the same time, it has a lower manufacturing difficulty, which is beneficial to improving the production efficiency of the packaging base pad.

[0018] In some possible embodiments of the present application, the cross-section of the support column is circular, rectangular or regular polygonal.

[0019] With such arrangement, the cross section of the support column can be of a regular shape, which can reduce the difficulty of manufacturing the support column, thereby improving the production efficiency of the packaging base pad.

[0020] In some possible embodiments of the present application, there are multiple base feet, there are multiple avoidance grooves, the multiple avoidance grooves are arranged corresponding to the multiple base feet, and the support column is arranged in at least some of the multiple avoidance grooves.

[0021] In this way, support columns are provided corresponding to at least part of the multiple feet to block at least part of the feet, thereby preventing at least part of the feet from being separated from the box body and falling into the avoidance groove as much as possible.

[0022] In the second aspect, an embodiment of the present application provides a packaging base pad, which is located below an electrical appliance, wherein the bottom of the electrical appliance is provided with a base foot threadedly connected thereto, and the packaging base pad is provided with an avoidance groove opposite to the base foot, and a support column is provided in the avoidance groove, and the support column is configured to abut against the base foot when the base foot moves in a direction away from the electrical appliance, and be crushed when the base foot continues to move in a direction away from the electrical appliance.

[0023] The packaging base pad of the embodiment of the present application can block the base when the base rotates relative to the refrigerator body and moves away from the refrigerator body due to vibration or other reasons during the transportation of the refrigerator, thereby preventing the base from separating from the refrigerator body and falling into the avoidance groove as much as possible. When the base moves further away from the refrigerator body, the support column is crushed, thereby preventing the base from bending and deforming due to excessive contact force between the support column and the base.

[0064] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0065] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and common meanings.

[0066] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0067] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0068] The terms "first", "second" and the like are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, features defined with "first", "second" and the like may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0069] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0070] In view of the technical problem in the related art that the bottom foot is easy to fall into the avoidance groove during the transportation of electrical appliances, the inventors have found that the reason is that the bottom foot is threadedly connected to the bottom of the electrical appliance. During the transportation of the electrical appliance, due to vibration of the electrical appliance, the bottom foot will rotate relative to the electrical appliance and move away from the electrical appliance. The depth of the avoidance groove in the packaging bottom pad is usually greater than the height of the bottom foot. The bottom of the avoidance groove cannot block the bottom foot, and the bottom foot is easy to separate from the electrical appliance and fall into the avoidance groove.

[0071] The inventor has tried to reduce the depth of the avoidance groove so that the depth of the avoidance groove is less than the height of the foot. When the foot rotates relative to the electrical appliance, the foot can abut against the bottom of the avoidance groove, and the bottom of the avoidance groove can block the foot to prevent the foot from separating from the electrical appliance and falling into the avoidance groove, thereby preventing the foot from being missed. However, when the foot abuts against the bottom of the avoidance groove, there is a large abutment force between the bottom of the avoidance groove and the foot. When the foot continues to move away from the electrical appliance, the abutment force continues to increase, causing the foot to bend and deform.

[0072] In view of this, an embodiment of the present application provides a packaging bottom pad, which is configured to abut against the bottom foot when the bottom foot moves in a direction away from the electrical appliance, and to be crushed when the bottom foot continues to move in a direction away from the electrical appliance. During the transportation of the electrical appliance, when the bottom foot rotates relative to the electrical appliance and moves in a direction away from the electrical appliance due to vibration or other reasons, the support column can block the bottom foot, and prevent the bottom foot from separating from the electrical appliance and falling into the avoidance groove as much as possible. When the bottom foot moves further in a direction away from the electrical appliance, the support column is crushed, which can avoid as much as possible the excessive abutment force between the support column and the bottom foot causing the bottom foot to bend and deform.

[0073] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0091] refer to Figure 4 and Figure 5 The refrigerator 200 may further include a foot 600, which may be located at the bottom of the refrigerator 200 and may be threadedly connected to the bottom of the refrigerator 200. When the refrigerator 200 is placed vertically, the foot 600 may be manually rotated to adjust the distance between the foot 600 and the bottom of the refrigerator 200, thereby adjusting the height of the cabinet 300 to meet the user's usage requirements.

[0092] For example, there may be a plurality of feet 600 , and the plurality of feet 600 may be distributed at intervals at the bottom of the refrigerator 200 .

[0093] The refrigerator 200 may include a mounting plate at the bottom thereof, and the foot 600 may be screwed to the mounting plate. Figure 6As shown, the mounting plate may be the first bottom plate 351, and the foot 600 may be threadedly connected to the first bottom plate 351. Alternatively, as Figure 7 As shown, the mounting plate can be a hinge plate 510 connected to the first bottom plate 351, and the foot 600 can be threadedly connected to the hinge plate 510. It is understandable that the mounting plate can also be other structures located at the bottom of the refrigerator 200, which will not be described in detail in the embodiment of the present application.

[0094] The following uses the hinge plate 510 as an example to describe the technical solution of the embodiment of the present application in detail.

[0095] refer to Figure 8 and Fig. 9 The packaging base pad 100 of the embodiment of the present application can be located under the electrical appliance. The packaging base pad 100 can be provided with an avoidance groove 110 opposite to the base foot 600. A support column 111 is provided in the avoidance groove 110. The support column 111 can be configured to abut against the base foot 600 when the base foot 600 moves in a direction away from the electrical appliance, and be crushed when the base foot 600 continues to move in a direction away from the electrical appliance.

[0096] like Fig.10 As shown, when the distance between the bottom end of the base foot 600 and the hinge plate 510 is the smallest, that is, when the base foot 600 and the hinge plate 510 are screwed together, there is a gap between the lower end of the base foot 600 and the top end of the support column 111 .

[0097] like Fig.11 As shown, during the transportation of the refrigerator 200, when the foot 600 rotates relative to the box body 300 and moves away from the box body 300 due to vibration or other reasons, the support column 111 can block the foot 600, and prevent the foot 600 from separating from the box body 300 and falling into the avoidance groove 110 as much as possible. When the foot 600 moves further away from the box body 300, the support column 111 is crushed, which can avoid the foot 600 bending and deformation caused by excessive contact force between the support column 111 and the foot 600.

[0098] like Fig.10 and Fig.11As shown, the distance H1 between the top of the support column 111 and the bottom surface of the hinge plate 510 can be less than the height H2 of the foot 600. In the process of transporting the refrigerator 200, when the foot 600 rotates relative to the box body 300 and moves in a direction away from the box body 300, the lower end of the foot 600 can abut against the upper end of the support column 111, and the support column 111 can block the foot 600. Since the distance H1 is less than the height H2, the foot 600 can be connected to the hinge plate 510, and the foot 600 is prevented from separating from the hinge plate 510 and falling into the avoidance groove 110 as much as possible. When the foot 600 continues to move in a direction away from the box body 300, the lower end of the foot 600 applies a greater abutment force to the upper end of the support column 111, and the support column 111 is crushed, which can avoid bending and deformation of the foot 600 as much as possible.

[0099] Exemplarily, when there are multiple feet 600, there may also be multiple avoidance grooves 110, and multiple avoidance grooves 110 may be provided corresponding to the multiple feet 600, and at least some of the avoidance grooves 110 may be provided with support columns 111. In this way, support columns 111 are provided corresponding to at least some of the multiple feet 600 to block at least some of the feet 600, and to prevent at least some of the feet 600 from being separated from the box body 300 and falling into the avoidance grooves 110 as much as possible.

[0100] For example, reference Fig. 9 , Fig.12 and Fig.13 The cross section of the support column 111 can be circular, rectangular or regular polygonal. For example, the regular polygon can be a regular triangle, a square or a regular pentagon. In other words, the cross section of the support column 111 can be a regular shape. This arrangement can reduce the difficulty of making the support column 111, thereby improving the production efficiency of the packaging base pad 100.

[0101] It is understandable that the cross-section of the support column 111 may also be an ellipse or other irregular shapes, which will not be described in detail in the embodiments of the present application.

[0102] In some possible embodiments of the present application, the direction along the bottom of the avoidance groove 110 pointing to the refrigerator 200, that is, along Fig.14 In the height direction z shown, the cross-sectional area of ​​the support column 111 can decrease. In this way, the strength of the support column 111 can be increased in the direction from the refrigerator 200 to the bottom of the avoidance groove 110, that is, it increases in the opposite direction of the height direction z. When the foot 600 continues to move away from the box body 300, the support column 111 can be gradually crushed, so that the support column 111 still has a sufficient height after being crushed to block the foot 600, thereby preventing the foot 600 from bending and deforming and the foot 600 from separating from the box body 300 as much as possible.

[0103] In some possible embodiments of the present application, Fig.14 , Fig.15 and Fig.16 As shown, the cross-sectional area of ​​the support column 111 can be continuously decreased. In this way, the strength of the support column 111 can be continuously increased in the direction of the refrigerator 200 pointing to the bottom of the avoidance groove 110, that is, it can be continuously increased in the opposite direction of the height direction z. When the foot 600 continues to move away from the box body 300, the support column 111 can be gradually crushed, so that the support column 111 still has a sufficient height when being crushed to block the foot 600, thereby preventing the foot 600 from bending and deforming and the foot 600 from separating from the box body 300 as much as possible.

[0104] For example, the support column 111 may be a prism or a frustum. Fig.14 As shown, the support column 111 may be a truncated cone. Fig.15 As shown, the support column 111 may be a rectangular pyramid. Fig.16 As shown, the support column 111 can be a square prism. It is understandable that the support column 111 can also be a prism or a frustum of other shapes, which will not be described in detail in the present embodiment of the application. The center line of the prism or frustum is located in the height direction z, which is the same as the moving direction of the base 600. The position of the abutment force between the base 600 and the crushed support column 111 will not change significantly compared to before the support column 111 is crushed, thereby improving the stability of the force position of the base 600 as much as possible, which is conducive to preventing the base 600 from bending and deformation.

[0105] In some other possible embodiments of the present application, Fig.17 and Fig.18 As shown, the cross-sectional area of ​​the support column 111 can be stepped down. With such a configuration, the strength of the support column 111 can be stepped up in the direction from the refrigerator 200 to the bottom of the avoidance groove 110, that is, stepped up in the opposite direction of the height direction z. When the foot 600 continues to move away from the box body 300, the support column 111 can be gradually crushed, so that the support column 111 still has a sufficient height when crushed to block the foot 600, thereby preventing the foot 600 from bending and deforming and the foot 600 from separating from the box body 300 as much as possible.

[0106] For example, along the bottom of the avoidance groove 110 pointing to the bottom of the box body 300, the support column 111 may include at least two support parts connected in sequence, the center lines of the at least two support parts are collinear, and the cross-sectional areas of the at least two support parts are sequentially reduced. Since the center lines of the at least two support parts are collinear, the position of the abutment force between the foot 600 and the crushed support column 111 will not change significantly compared to before the support column 111 is crushed, thereby improving the stability of the force position of the foot 600 as much as possible, which is conducive to preventing the foot 600 from bending and deformation.

[0107] like Fig.18 As shown, at least two supporting parts may include a first supporting part 112 and a second supporting part 113, the first supporting part 112 is closer to the bottom of the avoidance groove 110 than the second supporting part 113, the cross-sectional area of ​​the first supporting part 112 may be greater than the cross-sectional area of ​​the second supporting part 113, and the distance between the upper end of the first supporting part 112 and the bottom surface of the mounting plate may be less than the height of the foot 600. In other words, the number of supporting parts may be two, and the supporting column 111 including two supporting parts may effectively prevent the foot 600 from being separated from the box body 300 and prevent the foot 600 from being bent and deformed, and at the same time, it also has a lower manufacturing difficulty, which is conducive to improving the production efficiency of the packaging base pad 100.

[0108] It is understandable that the number of support parts can also be specifically set according to actual application conditions, and the embodiments of the present application will not be elaborated on this.

[0109] refer to Figure 8 The packaging base pad 100 may also be provided with a bottom plate support portion 120. When the refrigerator 200 is placed on the packaging base pad 100, the bottom plate support portion 120 abuts against the first bottom plate 351 to support the first bottom plate 351 to improve the stability of the refrigerator 200.

[0110] The bottom plate support portion 120 may be provided with a through hole 121 so that when the bottom plate support portion 120 abuts against the first bottom plate 351, external air can enter between the bottom plate support portion 120 and the first bottom plate 351 through the through hole 121, thereby preventing excessive adsorption force due to lack of air between the bottom plate support portion 120 and the first bottom plate 351 as much as possible, thereby improving the convenience of separating the bottom plate support portion 120 and the first bottom plate 351 when moving the refrigerator 200.

[0111] The left and right ends of the bottom plate support portion 120 may be provided with side plate positioning portions 130. When the refrigerator 200 is placed on the packaging base 100, the two side plate positioning portions 130 may limit the first side plate 331 and the second side plate 332 of the refrigerator 200 to position the refrigerator 200 in the width direction x, thereby improving the position accuracy of the refrigerator 200, so as to make the foot 600 as far as possible directly above the support column 111. Exemplarily, the length of the side plate positioning portion 130 in the depth direction y may be 18 mm. The height of the side plate positioning portion 130 in the height direction z may be 8 mm. It is understandable that the length and height of the side plate positioning portion 130 may be specifically set according to the actual application situation, and the embodiments of the present application will not be repeated here.

[0112] The packaging base pad 100 may also be provided with a door body support portion 140. Exemplarily, the door body support portion 140 may be located in front of the bottom plate support portion 120. When the refrigerator 200 is placed on the packaging base pad 100, the door body support portion 140 is located below the door body 400 and abuts against the door body 400 to support the door body 400 and prevent the door body 400 from shaking as much as possible, so as to improve the stability of the door body 400 of the refrigerator 200.

[0113] The packaging base pad 100 may also be provided with a bottom plate receiving portion 150. Exemplarily, the bottom plate receiving portion 150 may be located behind the bottom plate supporting portion 120. When the refrigerator 200 is placed on the packaging base pad 100, the second bottom plate 360 ​​is located in the bottom plate receiving portion 150 and abuts against at least part of the inner surface of the bottom plate receiving portion 150. The bottom plate receiving portion 150 may position the refrigerator 200 in the depth direction y through the second bottom plate 360, thereby improving the position accuracy of the refrigerator 200, so that the foot 600 is located directly above the support column 111 as much as possible.

[0114] The second bottom plate 360 ​​support portion 120 may be provided with a plurality of accommodating recessed portions 151. When the refrigerator 200 is placed on the packaging bottom pad 100, the accommodating recessed portions 151 are used to accommodate the connecting bolts connected to the second bottom plate 360, or the supporting bosses provided on the second bottom plate 360. During the transportation of the refrigerator 200, the connecting bolts or the supporting bosses may be prevented from colliding with the packaging bottom pad 100 as much as possible, thereby facilitating the connecting bolts or the supporting bosses from being deformed.

[0115] The packaging base pad 100 may also be provided with a back plate avoidance portion 160. Exemplarily, the back plate avoidance portion 160 may be located behind the support portion 120 of the second bottom plate 360. When the refrigerator 200 is placed on the packaging base pad 100, the back plate avoidance portion 160 is used to avoid the lower end of the third back plate 370 to improve the stability of the refrigerator 200. During the transportation of the refrigerator 200, the back plate can be prevented from colliding with the packaging base pad 100 as much as possible, thereby facilitating the back plate from being deformed.

[0116] The packing base 100 may also be provided with two corner recesses 170. When the refrigerator 200 and the packing base 100 fall during transportation, the corner recesses 170 can prevent the corners of the packing base 100 from being damaged as much as possible, thereby improving the structural reliability of the packing base 100.
