[0043] Figure 3 An exploded perspective view of the article storage container 200 and the guide rail assembly 300 according to an exemplary embodiment of the present utility model is shown; Figure 4 Shown is Figure 3 a perspective view of one of the connectors 510 in Figure 5 Shown is Figure 4 a perspective view of the connector 510 from another angle in Figure 6 Shown is Figure 3 a perspective view of another connector 520 in Figure 7 Shown is Figure 6 a perspective view of the connector 520 from another angle in Figure 8 Shown is Figure 3 a perspective view of the support member 400 in Figure 9 Shown is Figure 3 a perspective view of the article storage container 200 in

[0044] As Figure 3 shown, the refrigeration appliance 1000 further includes a support member 400. The support member 400 is disposed on a side of the guide rail assembly 300 away from the side wall 101 and extends along the depth direction y of the refrigeration appliance to provide an upper surface 401 for support. In this way, it is beneficial to stably support the article storage container 200 with a large capacity and requiring a lot of items to be carried in cooperation with the heavy-duty guide rails.

[0045] In the present utility model, the guide rail assembly 300 may be a metal guide rail, which includes a fixed rail and a sliding rail, and the support member 400 is disposed on the sliding rail. The guide rail assembly 300 is preferably a C-shaped rail that can withstand heavy loads. The support member 400 can be constructed as a metal piece riveted to the side of the sliding rail to provide sufficient support force to support the article storage container 200 with a large capacity and requiring a lot of items to be carried.

[0046] On the upper surface 401, connectors 510 and 520 are provided for connecting with the article storage container 200. The connectors 510 and 520 are used to cooperate with the mating structures 203 on the article storage container 200 to form stable support for the article storage container 200.

[0047] As Figure 3-7 Shown in the figure, the connectors 510 and 520 include upper walls 511 and 521 supported on the upper surface 401. Among them, limiting parts 514 and 524 are provided on the upper walls 511 and 521 to limit the displacement of the connectors 510 and 520 relative to the support 400 or the article storage container 200 in the width direction x of the refrigeration appliance. Thus, it is beneficial to improve the problem of excessive shaking caused by the over-large width dimension due to manufacturing tolerances and assembly tolerances, and improve the user experience.

[0048] The connectors 510 and 520 include side plates 513 and 523 vertically extending downward from the sides of the upper walls 511 and 521 away from the side wall 101. Connecting parts 515 and 525 for connecting with the support 400 are provided on the side plates 513 and 523. It is beneficial to form connection or limit with the connectors on two different mounting surfaces of the support 400. In this way, it is beneficial to ensure that the connectors 510 and 520 are not easily separated from the support 400 even when used to connect the article storage container 200 with a large capacity and need to carry a lot of articles, and form a stable connection.

[0049] Furthermore, the connecting parts 515 and 525 include connecting columns 515b and 525b protruding from the side plates 513 and 523 and buckles 515a and 525a extending reversely from both sides of the connecting columns 515b and 525b. The thickness of the buckles 515a and 525a is greater than the thickness of the connecting columns 515b and 525b. It is beneficial to improve the connection strength between the connectors 510 and 520 and the support 400, and can be applied to connect the article storage container 200 with a large capacity and need to carry a lot of articles.

[0050] The article storage container 200 includes a peripheral wall forming a storage space with an upward opening. Among them, mating structures 203 for cooperating with the support 400 are provided on the two outer side walls 202.

[0051] In some specific embodiments, the mating structure 203 is formed at the lower part of the outer side wall 202. Preferably, a step 220 facing the storage space is formed in the middle of the outer side wall 202, and the mating structure 203 is formed below the step 220. Thus, it is beneficial to make the mating structure invisible from the front side of the refrigeration appliance 1000.

[0052] The mating structure 203 can extend along the depth direction y of the article storage container. In a specific embodiment, the mating structure 203 is formed with guide ribs 210 protruding from the corresponding outer side wall 202 under the step 220. The lower surface of the guide rib 210 forms a mating surface 201 facing the upper surface 401 of the support member 400. In this way, the guide rib 210 is conducive to the fixed connection with the upper surface 401.

[0053] In addition, the mating structure 203 includes a mating surface 201 disposed opposite to the upper surface 401 of the support member 400. Along the height direction z of the refrigeration appliance, a gap is provided between the upper surface 401 of the support member 400 and the mating surface 201. The formation of the gap is conducive to the air in the storage chamber 1001 flowing through the gap, which is beneficial to reducing the condensation or even icing phenomenon caused by the air passage blockage between the guide rail assembly, the guide rail assembly 300 and the article storage container 200.

[0054] In a preferred embodiment, a recess 402 is formed on the upper surface 401 of the support member 400. The recess 402 forms a gap between the upper surface 401 and the mating surface 201. In this way, the gap is large enough so that the air in the refrigeration appliance can have a certain air volume and air speed when passing through the gap, which is beneficial to taking away the water vapor accumulated near the guide rail assembly to reduce the possibility of condensation or icing.

[0055] In a preferred embodiment, the connectors 510, 520 include a first connector 510 located on the front side of the support member 400 and a second connector 520 located on the rear side of the support member 400. The first connector 510 and the second connector 520 cooperate to limit the displacement of the article storage container 200 in the depth direction y of the refrigeration appliance.

[0056] As Figure 4-5 shown, the first connector 510 includes a first limiting portion 514 extending from the lower surface of the first upper wall 511 thereof. The first limiting portion 514 can be configured as a convex block to be in shape fit with the hole 406 on the upper surface 401. The first limiting portion 514 limits the displacement of the first connector 510 relative to the support member 400 in the width direction x of the refrigeration appliance, so as to improve the problem that the upper part of the first connector is prone to displacement in the width direction of the refrigeration appliance, resulting in the shaking of the article storage container when the capacity of the article storage container 200 is large and it carries a lot of articles, and improving the user experience.

[0057] Preferably, the convex block is square, and the hole 406 is designed as a square hole matching the shape and size of the square convex block.

[0058] In a specific embodiment, the first connector 510 includes an upper wall 511 and an engaging portion 512 protruding from the upper wall 511. The engaging portion 512 vertically protrudes upward from the upper surface of the upper wall 511; a locking hole 211 is formed on the mating surface 201. By the cooperation of the engaging portion 512 of the first connector 510 fixed to the upper surface 401 and the locking hole 211, the article storage container 200 is installed on the support 400 with its movement restricted, which is beneficial to reducing the noise generated during the use of the article storage container 200 and improving the user experience.

[0059] Further, the engaging portion 512 includes elastic arms 512a and fixed arms 512b distributed front and back along the length direction of the first fitting 510. The elastic walls 512a and the fixed arms 512b are respectively in contact with the locking hole 211. It is possible to restrict the movement of the article storage container 200 relative to the guide rail assembly 300 in the height direction and the depth direction of the storage room 1001. Therefore, when being pulled out or pushed into the storage room 1001, it is not easy to shake, which is beneficial to improving the stability and reliability of the connection between the article storage container 200 and the storage room 1001.

[0060] The first connector 510 includes a first side plate 513 vertically extending downward from a side of the first upper wall 511 away from the side wall 101. A first connecting portion 515 for connecting with the outer surface 403 of the support 400 is provided on the first side plate 513.

[0061] Further, the first connecting portion 515 includes a first connecting column 515b protruding from the first side plate 513 toward the side wall 101 and first buckles 515a extending reversely from both sides of the first connecting column 515b.

[0062] In some preferred embodiments, the thickness of the first buckle 515a is greater than the thickness of the first connecting column 515b.

[0063] The first side plate 513 is further provided with a stopping portion. The stopping portion is formed as a first elastic arm 517 received in the middle of the first side plate 513 and a first clamping column 516 formed at the free end of the first elastic arm 517 facing the side wall 101. A hole for cooperating with the first clamping column 516 to stop is provided on the support 400. Thus, it is possible to prevent the first connector 510 from falling off the support 400 due to upward displacement.

[0064] Such as Figure 6-7As shown, the second connector 520 is fixed to the rear part of the support member 400. The second connector 520 includes a second upper wall 521 and a limiting groove formed as a second limiting portion 524 along the depth direction y of the refrigeration appliance from the front end of the second upper wall 521 thereof. In this way, the displacement of the second connector 520 relative to the article storage container 200 in the width direction x of the refrigeration appliance is restricted, so as to improve the problem of excessive shaking of the article storage container caused by the excessive width dimension due to manufacturing tolerances and assembly tolerances.

[0065] Preferably, the second limiting portion 524 is located in the middle of the second upper wall 521 in the width direction of the refrigeration appliance.

[0066] The second connector further includes a slot portion 522 protruding from the second upper wall 521. The slot portion 522 is formed by extending from the upper surface of the second upper wall 521. By restricting a part of the guide rib 210 of the article storage container 200 therein through the slot portion 522, it is beneficial to reduce the noise generated during the use of the article storage container 200 and improve the user experience.

[0067] Furthermore, the slot portion 522 has a first side wall 522a facing the side wall 101 of the storage chamber 1001, and the first side wall 522a extends backward from the front end of the second upper wall 521. The first side wall 522a of the slot portion 522 can be used to define the movement of the article storage container 200 relative to the guide rail assembly in the width direction of the storage chamber 1001. In addition, the first side wall 522a of the slot portion 522 also has a guiding function. It can not only guide the protruding rib 212 at the rear end of the guide rib 210 into the slot portion 522 to improve the convenience of installation, but also guide the assembly of the protruding rib 214 on the mating surface 201 and the second limiting portion 524.

[0068] In addition, the slot portion 522 further includes an upper wall 522b that is substantially V-shaped with the second support portion 521. The opening angle of the slot portion 522 is less than 90°. Correspondingly, the shape of the protruding rib 212 is V-shaped, and the inclination angle of the protruding rib is less than the opening angle of the slot portion. In this way, under the guiding action of the inclined upper wall 522b of the slot portion 522, the protruding rib 212 is easily inserted into the slot portion 522.

[0069] The second connector 520 includes a second side plate 523 vertically extending downward from the side of the second upper wall 521 away from the side wall 101. A second connecting portion 525 connected to the outer surface 403 of the support member 400 is provided on the second side plate 523.

[0070] Furthermore, the second connecting portion 525 includes a second connecting column 525b protruding from the second side plate 523 toward the side wall 101 and snap fasteners 525a extending reversely from both sides of the second connecting column 525b.

[0071] The thickness of the second buckle 525a is the same as that of the first buckle 515a, and the thickness of the second buckle 525a is also greater than the thickness of the second connecting post 525b.

[0072] The second side plate 513 is also provided with a stop portion. The stop portion is formed by a second elastic arm 527 received in the middle of the second side plate 523 and a second latch post 526 formed at the free end of the second elastic arm 527 facing the side wall 101. A hole for cooperating with the second latch post 526 to stop is provided on the support member 400. Thus, the second connector 520 is prevented from falling off the support member 400 due to forward displacement.

[0073] In some specific embodiments, in order to improve the strength of the guide rail rib 210 and the second fitting 520 to ensure the reliability of the connection, a plurality of first reinforcing ribs 213 may be provided on the guide rail rib 210; or a plurality of second reinforcing ribs 526 may be provided on the rear side of the slot portion 522.

[0074] In a preferred solution, the first connector 510 and the second connector 520 can be cooperated to limit the displacement of the article storage container 200 in the depth direction y of the refrigeration appliance.

[0075] In some specific embodiments, the first connector 510 has a horizontally arranged buckle 515a, and the second connector 520 has a vertically arranged buckle 525a. At this time, the first connector 510 is snapped onto the support member 400 from top to bottom to provide the first connector 510 with forward and lateral displacement limitations for the article storage container 200. The second connector 520 is snapped onto the support member 400 from front to back to provide the second connector 520 with backward and lateral displacement limitations for the article storage container 200. Thus, when the article storage container 200 is pulled out or pushed into the storage room 1001, it is not easy to shake, which is beneficial to improving the stability and reliability of the connection between the article storage container 200 and the storage room 1001.

[0076] Due to the different buckle directions and the perpendicular installation directions, when the article storage container is pulled or pushed, the first connector and the second connector will not be disengaged from the support member at the same time, which is beneficial to ensuring the safety of the use of the article storage container 200.

[0077] In the present utility model, the guide rail assembly 300, the support member 400, and the connectors 510, 520 are symmetrically arranged on both sides of the article storage container 200, and the article storage container 200 is provided with the rib 214 only on the mating surface 201 on one side thereof, which is beneficial to the smooth progress of the assembly process in the case of manufacturing tolerances of the article storage container.

[0078] In some specific embodiments, especially when the guide rail assembly is a heavy-duty guide rail, higher requirements are placed on the stability of the heavy-duty guide rail assembly. Generally, the connecting rail between the heavy-duty guide rail and the side wall 101 is wider to provide a greater moment, so a support member can provide a larger support surface. However, in some refrigeration systems, condensation or icing is likely to occur on the heavy-duty guide rail.

[0079] In the present utility model, the support member 400 is preferably constructed as a sheet metal part, including a bent portion forming the upper surface 401 and a main body portion forming the outer surface 403 and fixedly connected to the guide rail assembly 300 to provide sufficient supporting force for the heavy-duty container.

[0080] In order to form a recess 402 on the upper surface 401 of the support member 400 to provide a sufficiently large gap, a cut 404 is provided in the region where the upper surface 401 and the outer surface 403 of the support member 400 intersect to facilitate the formation of the recess 402, and the cut 404 also additionally provides a flow path for air.

[0081] Furthermore, a bent portion 405 is provided on the support member 400 below the connectors 510, 520 and bent towards the article storage container. The bent portion 405 is beneficial for providing a space between the support member and the guide rail assembly to accommodate the connecting portion of the fitting passing through the support member 400. Of course, the bent portion 405 is also beneficial for enhancing the strength of the support member 400.

[0082] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the disclosure of the present utility model, even when only a single embodiment is described with respect to a specific feature. The feature examples provided in the disclosure of the present utility model are intended for illustrative purposes only and not for limitation, unless explicitly stated otherwise. In specific implementations, multiple features can be combined with each other according to actual needs and when technically feasible. Various substitutions, modifications, and alterations can also be conceived without departing from the spirit and scope of the present utility model.
