DETAILED DESCRIPTION

[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0034] The present disclosure provides a box of a refrigeration device, comprising a box body, a drawer door, a guide rail assembly and a buffer. The inner wall of the box body is provided with a guide rail; the drawer door switches between opening and closing relative to the box body; the guide rail assembly comprises a guide rail, a first end of the guide rail is connected to the drawer door, a second end of the guide rail is provided with a limiting portion, and the guide rail is slidably connected to the guide rail; the buffer is provided between the limiting portion and the guide rail, and when the drawer door is opened to a first position, the buffer is respectively in contact with the guide rail and the limiting portion.

[0035] In the embodiment of the present disclosure, the limiter is used to limit the maximum travel of the drawer door. When the drawer door is opened to the first position and reaches the maximum travel, the guide member and the limiter abut against each other, thus limiting the drawer door. A buffer is provided between the guide member and the limiter to buffer the collision between the guide member and the limiter, thereby reducing the noise and vibration generated when the guide member and the limiter collide, and improving the user experience.

[0036] Refrigeration equipment refers to electrical equipment used to provide a low-temperature environment, such as refrigerators, freezers, etc., but is not limited to these.

[0037] Generally speaking, a refrigeration device has a drawer structure for storing items that need to be refrigerated or frozen, and the drawer structure is opened and closed in a pull-out manner. Of course, the refrigeration device can be provided with a rotatable door body and a corresponding storage space as required, and this is not limited, and those skilled in the art can set it as required.

[0038] Figure 1 is a schematic structural diagram of a box body of a refrigeration device according to an exemplary embodiment. Figure 2is a structural schematic diagram of a drawer door and guide rail assembly according to an exemplary embodiment. Figure 3 yes Figure 2 The enlarged view of A in the figure. Figure 1 , Figure 2 , Figure 3 As shown, the box of the refrigeration equipment includes a box body 1, a drawer door 11, a guide rail assembly 2 and a buffer member 3. The inner wall of the box body 1 is provided with a guide member 12; the drawer door 11 is opened or closed relative to the box body 1; the guide rail assembly 2 includes a guide rail 21, the first end of the guide rail 21 is connected to the drawer door 11, the second end of the guide rail 21 is provided with a limiting portion 212, and the guide rail 21 is slidably connected to the guide member 12; the buffer member 3 is provided between the limiting portion 212 and the guide member 12, and when the drawer door 11 is opened to the first position, the buffer member 3 abuts against the guide member 12 and the limiting portion 212 respectively.

[0039] In the embodiment of the present disclosure, a buffer member 3 is provided between the limit portion 212 and the guide member 12, which can buffer the collision between the limit portion 212 and the guide member 12, reduce the vibration and noise when the limit portion 212 collides with the guide member 12, and improve the user experience.

[0040] In some embodiments, the drawer door 11 can be integrally provided or fixedly connected with the drawer body forming the storage space, or the drawer door 11 can be provided separately, and the drawer body forming the storage space can be detachably connected with the drawer door 11. Based on this, the guide rail assembly 2 can be connected only to the drawer door 11, or it can be connected to the drawer body while being connected to the drawer door 11.

[0041] In some embodiments, the buffer member 3 is a flexible structure, which absorbs the energy of the collision between the limiting portion 212 and the guide member 12 through deformation of the flexible structure, thereby reducing vibration and noise.

[0042] In some embodiments, the buffer member 3 is made of silicone. Those skilled in the art may also select other flexible materials, such as rubber, etc., as needed, and the present disclosure does not limit this.

[0043] In some embodiments, the portion between the first end and the second end of the guide rail 21 is slidably connected to the guide member 12, and when the guide rail 21 slides to the sliding connection portion with the guide member 12 at the second end, the drawer door 11 opens to the first position.

[0044] When the drawer door 11 is opened to the first position, the buffer member 3 abuts against the guide member 12 and the limit portion 212 respectively. At this time, the limit portion 212 limits the guide member 12, and the drawer door 11 is opened to the maximum. When the drawer door 11 is closed, the buffer member 3 is separated from at least one of the guide member 12 and the limit portion 212. Figure 1As shown, at this time, the lower drawer door 11 is opened to the first position.

[0045] It should be noted that Figure 1 The box body of the refrigeration device with two drawer doors 11 is shown in the figure, but it should be understood that this is only an exemplary display, and does not mean that the box body of the refrigeration device in the present disclosure can only be provided with two drawer doors 11. In fact, the box body of the refrigeration device in the embodiment of the present disclosure can be provided with one or more drawer doors 11 as needed, and can also be provided with one or more storage spaces using double doors or single doors that are opened and closed by rotation as needed. Those skilled in the art can make their own choices as needed, and the present disclosure does not limit this.

[0046] like Figure 2 , Figure 3 As shown, the buffer member 3 can be arranged on the guide rail 21. Generally speaking, the arrangement form of the limiting portion 212 is relatively fixed, so the arrangement position and form of the buffer member 3 are relatively simple, which can improve versatility.

[0047] Alternatively, the buffer member 3 may also be disposed on the inner wall of the box body 1, and the buffer member 3 does not need to be moved, thereby reducing the risk of deformation and falling off during movement.

[0048] Alternatively, the buffer 3 can also be arranged on the inner wall of the box body 1 and the guide rail 21 at the same time, in which case at least two buffers 3 are required, which are arranged on the inner wall of the box body 1 and the guide rail 21 respectively. This can improve the buffering capacity, and even if one of the buffers 3 is damaged, it can maintain a certain buffering effect.

[0049] like Figure 2 , Figure 3 As shown, a guide groove 211 is provided between the first end and the second end of the guide rail 21 , and the limiting portion 212 at least partially fills the guide groove 211 .

[0050] The buffer member 3 is disposed on the guide rail 21 . The buffer member 3 includes a buffer block 31 located in the guide groove 211 . The buffer block 31 abuts against the limiting portion 212 .

[0051] In the embodiment of the present disclosure, the buffer block 31 abuts against the limiting portion 212, and the limiting portion 212 can provide certain support for the buffer block 31 to prevent the buffer block 31 from moving when it collides with the guide member 12. At the same time, the buffer block 31 does not need to move in the guide groove 211, thereby preventing the buffer block 31 from being worn during the movement.

[0052] Figure 4 is a schematic structural diagram of a buffer according to an exemplary embodiment. Figure 3 , Figure 4As shown, a cavity is provided inside the buffer block 31 , and an opening 312 communicating with the inside and outside of the cavity is formed on the first surface 311 of the buffer block 31 . The limiting portion 212 contacts the first surface 311 and at least partially blocks the opening 312 .

[0053] The cavity can increase the deformation capacity of the buffer block 31 when it is impacted, making the collision more gentle and quiet when the drawer door 11 is opened. The cavity is provided with an opening 312 to prevent the pressure of the air in the cavity from increasing and damaging the buffer block 31 after being compressed.

[0054] In the embodiment of the present disclosure, the limiting portion 212 blocks the opening 312, which can hinder the airflow in the cavity from flowing out of the cavity to a certain extent, thereby reducing the speed of the airflow outflow, so that the rigidity of the buffer block 31 increases at the moment of a violent collision, and it will not directly reach the maximum deformation and fail to play the due buffering role. When the collision is relatively mild, the airflow itself flows out slowly, and even if there is a blockage by the limiting portion 212, the speed of the airflow outflow does not change much, and the buffer block 31 will not show an instantaneous increase in rigidity, so that the buffer block 31 shows sufficient flexibility.

[0055] In some embodiments, the limiting portion 212 is in closed contact with the circumferential edge of the opening 312 to cover the opening 312 .

[0056] In this embodiment, the limiting portion 212 and the opening 312 of the buffer block 31 completely form an airtight structure, which can maximize the instantaneous rigidity of the buffer block 31 when a violent collision occurs, effectively deal with the collision, and avoid the problem of insufficient buffering effect caused by the buffer member 3 being too soft. When the collision is relatively mild, the buffer block 31 will gradually lose the airtightness between the limiting portion 212 and the opening 312 of the buffer block 31 due to the gradual deformation, so that the buffer block 31 has better flexibility.

[0057] In some embodiments, the limiting portion 212 includes a sheet-like structure protruding from the groove wall or the groove bottom in the guide groove 211 , which has a simple processing technology and is easy to form an airtight seal with the opening 312 of the buffer member 3 .

[0058] Figure 5 yes Figure 4 A schematic structural diagram of the buffer member 3 from another perspective, as shown in FIG. Figure 4 , Figure 5 As shown, the buffer member 3 includes a fixing rod 313 and a fixing cap 314. One end of the fixing rod 313 is connected to the buffer block 31, and the other end extends in a direction away from the buffer block 31; the fixing cap 314 gradually shrinks from one end close to the buffer block 31 to one end away from the buffer block 31 to form a hollow umbrella-shaped structure, and the shrinkage center is sleeved on the fixing rod 313.

[0059] like Figure 3As shown, a fixing hole 213 is formed in the groove wall of the guide groove 211 , and the fixing cap 314 passes through the fixing hole 213 after being shrunk, so that the fixing hole 213 is located between the fixing cap 314 and the buffer block 31 .

[0060] In this embodiment, the fixing cap 314 of the buffer member 3 is folded and compressed and then passed through the fixing hole 213, and the fixing cap 314 is expanded. Since the fixing caps 314 and the buffer block 31 at both ends of the fixing hole 213 are larger than the fixing hole 213, the buffer block 31 will be firmly fixed on the guide groove 211 to prevent the buffer block 31 from falling off.

[0061] In some embodiments, the portion of the fixing rod 313 located between the fixing cap 314 and the buffer block 31 has a diameter that is the same as the diameter of the fixing hole 213, or is slightly larger than the diameter of the fixing hole 213, thereby making the fixing rod 313 and the fixing hole 213 more secure, reducing the shaking between the fixing rod 313 and the fixing hole 213, and also reducing the wear on the fixing rod 313.

[0062] In some embodiments, the edge of the fixing hole 213 is thickened to increase the contact area with the fixing rod 313 to avoid the edge of the fixing hole 213 being too thin to cut the fixing rod 313 and reduce the life of the fixing rod 313.

[0063] like Figure 4 , Figure 5 As shown, in some embodiments, on a side of the fixing cap 314 opposite to the buffer block 31 , the fixing rod 313 is protruded from the fixing cap 314 .

[0064] In this embodiment, the fixing rod 313 protrudes from the fixing cap 314 to form a handle that is easy to grasp. When the fixing cap 314 is passed through the fixing hole 213, the operator can grasp the handle for easy installation.

[0065] In some embodiments, the portions of the fixing rod 313 located on both sides of the fixing cap 314 may have different diameters. For example, the diameter of the portion of the fixing cap 314 located on the side opposite to the buffer block 31 may be smaller than the portion between the fixing cap 314 and the buffer member 3. Of course, the present disclosure is not limited thereto, and those skilled in the art may set the diameter of the fixing rod 313 as needed to facilitate the operator to grasp it.

[0066] like Figure 3 , Figure 4 , Figure 5 As shown, the buffer block 31 includes a second surface 315 and a third surface 316 respectively opposite to the groove walls on both sides of the guide groove 211. The second surface 315 and the third surface 316 are respectively provided with a concave-convex structure 317, which is interference fit with the groove wall of the guide groove 211.

[0067] The concavo-convex structure 317 can effectively increase the friction between the buffer block 31 and the groove wall of the guide groove 211. The concavo-convex structure 317 and the groove wall of the guide groove 211 are set to be interference fit, which can further enhance the friction between the buffer block 31 and the guide groove 211, and prevent the buffer block 31 from falling off after being impacted by a collision. Even if the fixing rod 313 fails, such as breaking, the concavo-convex structure 317 of the buffer block 31 can still fix the buffer block 31 on the guide groove 211.

[0068] In some embodiments, Figure 4 , Figure 5 As shown, the concave-convex structure 317 includes convex ribs intersecting with the extending direction of the guide groove 211 .

[0069] In this embodiment, the convex rib is arranged to intersect with the extension direction of the guide groove 211, which can play a strong limiting role on the buffer block 31 in the extension direction of the guide groove 211, prevent the buffer block 31 from moving in the extension direction of the guide groove 211, and improve the reliability of the buffer block 31.

[0070] In some embodiments, the convex rib is arranged to be perpendicular to the extension direction of the guide groove 211 , so as to limit the movement of the buffer block 31 in the extension direction of the guide groove 211 to the maximum extent.

[0071] In some embodiments, Figure 3 , Figure 4 , Figure 5 As shown, either the second surface 315 or the third surface 316 is provided with an orientation block 318 protruding from the surface of the buffer block 31 , and a groove wall of the guide groove 211 opposite to the orientation block 318 is provided with an orientation notch 214 for the orientation block 318 to pass through.

[0072] If the buffer block 31 is set to a completely symmetrical structure, it is easy to install the buffer block 31 in a wrong direction, which reduces the buffering effect of the buffer block 31 and even reduces the service life of the buffer block 31.

[0073] In this embodiment, an orientation block 318 is provided on one side of the buffer block 31, which can play a role in distinguishing the direction during installation, making it easier for the operator to distinguish the installation direction. If the direction is wrong, the buffer block 31 cannot be installed into the guide groove 211 due to the existence of the orientation block 318, thereby reducing the probability of installation errors and becoming an effective fool-proof design.

[0074] Figure 6 is a schematic structural diagram of a buffer member 3 and a guide member 12 according to an exemplary embodiment. Figure 3 , Figure 6As shown, the guide member 12 includes a first roller arranged on the inner wall of the box body 1, the first roller contacts the guide groove 211 and is movable along the extension direction of the guide groove 211, and the buffer block 31 includes a fourth surface 319 facing the first roller, and the fourth surface 319 is tangent to the first roller.

[0075] In this embodiment, by setting the fourth surface 319 where the buffer block 31 contacts the first roller when the drawer door 11 is pulled to the first position to be tangent to the first roller, the contact area between the first roller and the buffer block 31 can be increased, and the pressure of the first roller on the buffer block 31 can be reduced, thereby reducing the wear of the first roller on the buffer block 31 and extending the service life of the buffer block 31.

[0076] In some embodiments, the guide member 12 includes a first roller disposed on the inner wall of the box body 1 , and the buffer member 3 is disposed on the inner wall of the box body 1 , spaced apart from the first roller.

[0077] In this embodiment, the buffer member 3 disposed on the inner wall of the box body 1 is spaced apart from the first roller also disposed inside the box body 1, so as to avoid interference of the buffer member 3 with the first roller and ensure that the first roller can always rotate normally.

[0078] In some embodiments, the guide member 12 may also be a guide block integrally provided with the inner wall of the box body 1 .

[0079] Figure 7 is a structural schematic diagram of a drawer door and guide rail assembly according to an exemplary embodiment. Figure 8 is a structural schematic diagram of a drawer door and guide rail assembly according to another exemplary embodiment. Fig. 9 It is a schematic diagram of the structure of the auxiliary track. Figure 7 , Figure 8 , Fig. 9 As shown, the guide rail assembly 2 also includes an auxiliary rail 22 arranged on the inner wall of the box body 1 and a second roller 215 arranged at the second end of the guide rail 21 . The second roller 215 is slidably abutted against the auxiliary rail 22 to balance the weight of the drawer door 11 .

[0080] In some embodiments, the width of the drawer door 11 is less than or equal to 800 mm.

[0081] Generally speaking, drawers with a drawer door 11 width less than or equal to 800 mm use simple metal rails instead of linear slide rails, which will generate large collision noise and vibration when the drawer door 11 is pulled to the limit. The box body disclosed in the present invention can solve the problem of excessive noise and vibration.

[0082] In some embodiments, the width of the drawer door 11 is less than or equal to 750 mm.

[0083] The width of the drawer door 11 refers to the length value measured in the horizontal direction perpendicular to the drawing direction of the drawer door 11 when the refrigeration device is in the working state. Alternatively, the length value of the drawer door 11 is measured in the spacing direction of the guide rails 21 on both sides of the drawer door 11.

[0084] Fig.10 A refrigeration device according to an exemplary embodiment is shown. Fig.10 As shown, a cabinet including a refrigeration arrangement of the present disclosure is provided.

[0085] In the embodiment of the present disclosure, when the drawer door 11 of the refrigeration equipment is pulled outward to the limit, the guide member 12, the buffer member 3 and the limit portion 212 are abutted in sequence, and the buffer member 3 plays a buffering role between the guide member 12 and the limit portion 212. The guide member 12 and the limit portion 212 will not collide directly, which can greatly reduce the noise and vibration when the drawer door 11 is opened to the limit position.

[0086] Fig.11 A refrigeration device according to an exemplary embodiment is shown. Fig.11 As shown, the drawer door 11 of the refrigeration device may be a French refrigerator drawer door 11 with a width less than or equal to 750 mm, the refrigeration device may be a French refrigerator, and the refrigeration device may have one or more drawer doors 11. In some embodiments, the refrigeration device may have a double-door storage space that opens and closes in a rotating manner in addition to the drawer structure. Fig.11 The figure shows a French refrigerator with two drawer doors 11 and a double-door accommodating space, but it should be noted that the present disclosure is not limited to this. Those skilled in the art can also set the double door to a single door or other opening and closing forms as needed, and can also adjust the number of drawer doors 11 to other numbers, and the present disclosure does not limit it.

[0087] Generally speaking, the drawer structure includes a drawer door 11 and a drawer body forming a receiving space. The drawer door 11 and the drawer body can be integrally arranged or fixedly connected, or can be arranged as a separate structure, which is not limited in the present disclosure.

[0088] It is to be understood that in the present disclosure, "plurality" refers to two or more than two, and other quantifiers are similar. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. The singular forms "a", "the" and "the" are also intended to include plural forms, unless the context clearly indicates other meanings.

[0089] It is further understood that the terms "first", "second", etc. are used to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other, and do not indicate a specific order or degree of importance. In fact, the expressions "first", "second", etc. can be used interchangeably. For example, without departing from the scope of the present disclosure, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information.

[0090] It will be further understood that the terms “center”, “longitudinal”, “lateral”, “front”, “back”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present embodiment 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.

[0091] It can be further understood that, unless otherwise specified, “connection” includes a direct connection without other components between the two, and also includes an indirect connection with other components between the two.

[0092] It is further understood that, although the operations are described in a specific order in the drawings in the embodiments of the present disclosure, it should not be understood as requiring the operations to be performed in the specific order shown or in a serial order, or requiring the execution of all the operations shown to obtain the desired results.
