Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a support structure, drawer assembly and refrigerator. Background Technology

[0002] Drawers are common storage containers in daily life. They slide back and forth along support rails to open or close the storage space, making it convenient for users to access items. Drawers are widely used in daily life; for example, drawers are usually installed in the cooling compartment of refrigerators for easy access to items.

[0003] However, in the relevant technologies, the drawer generates a lot of friction during the sliding process, and the drawer is also prone to swaying left and right during the sliding process, which causes the drawer to slide obstructed, making it impossible for users to open or close the storage space smoothly, resulting in a poor user experience. Utility Model Content

[0004] In view of this, this application provides a support structure, a drawer assembly, and a refrigerator, which can reduce the sliding friction of the drawer and limit the drawer's swing, enabling the drawer to slide smoothly and thus improving the user experience.

[0005] Specifically, this application is implemented through the following technical solution: In a first aspect, this application provides a support structure, including a support base and a guide base.

In the direction from the first guide portion to the third support side, the support portion also includes a third arcuate convex surface protruding from the third support side.

[0010] In one embodiment, the support base is further provided with a connecting portion between the top end and the bottom end, and at least a portion of the third arcuate convex surface protrudes from the connecting portion in the direction along the first guide portion toward the third support side.

[0011] In one embodiment, the support base is further provided with at least one positioning part connected to the connecting part, and at least one positioning part protrudes from the connecting part in the direction from the third support side to the first guide part.

[0012] In one embodiment, at least one positioning part includes a first positioning part, and the support base is provided with a connecting hole that passes through the connecting part and the first positioning part in sequence, the connecting hole being used to install fasteners.

[0013] In one embodiment, at least one positioning part includes a second positioning part, which has a positioning groove extending from the bottom end to the top end.

[0014] Secondly, this application also provides a drawer assembly, including a support rail, a drawer, and a support structure according to any of the above embodiments. At least a portion of the support structure is connected to the support rail, with a first support side and a second support side disposed opposite to each other along the length direction of the support rail, and a top end and a bottom end disposed opposite to each other along the height direction of the support rail. The drawer is provided with a mating rail that is slidably connected to the support rail, the mating rail being capable of reciprocating within a support groove along the length direction of the support rail, causing the mating rail to abut against a first arc-shaped convex surface.

[0015] In one embodiment, a first mounting groove is provided on the side of the support rail that abuts against the mating rail, the support seat is located in the first mounting groove, and the support seat is provided with a second arc-shaped convex surface. At least a portion of the second arc-shaped convex surface protrudes out of the first mounting groove in the direction from the bottom end to the top end.

[0016] In one embodiment, along the length of the support rail, the support rail is provided with a first support surface and a second support surface located on both sides of the first mounting groove. The first support surface is disposed near the first support side, and the second support surface is disposed near the second support side. In the direction from the bottom end to the top end, the second support side is flush with the second support surface, and the second arc-shaped convex surface is higher than the second support surface.

[0019] The support structure provided in this application has the following beneficial effects: The support structure provided in this application utilizes a support portion and a first guide portion to form a support groove, allowing the drawer to slide along the support groove. Simultaneously, this application also provides a first arc-shaped convex surface protruding into the support groove on the side of the first guide portion facing the support groove. This allows the drawer to form point or line contact with the first arc-shaped convex surface, reducing the contact area between the drawer and the first guide portion within the support groove, thereby reducing sliding friction and resistance. Furthermore, the first arc-shaped convex surface also reduces the gap between the drawer and the first guide portion, preventing the drawer from swaying left and right within the support groove, thus improving the smoothness of the drawer's sliding.

[0020] Therefore, the drawer assembly with a support structure provided in this application can also improve the smoothness of drawer sliding, thereby enhancing the user experience. It is understood that the drawer assembly can be applied to any furniture and / or household appliance requiring storage functions, such as cabinets, tables, and refrigerators. Accordingly, the refrigerator with the drawer assembly provided in this application can also improve the smoothness of drawer sliding, thereby enhancing the user experience of the refrigerator.

Detailed Implementation

[0038] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0039] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures). If the specific posture changes, the directional indications or positional relationships will also change accordingly.

[0040] Drawers are common storage containers in daily life. They slide back and forth along support rails to open or close the storage space, making it convenient for users to access items. Drawers are widely used in daily life; for example, drawers are usually installed in the cooling compartment of refrigerators for easy access to items.

[0041] However, in the relevant technologies, the drawer generates a lot of friction during the sliding process, and the drawer is also prone to swaying left and right during the sliding process, which causes the drawer to slide obstructed, making it impossible for users to open or close the storage space smoothly, resulting in a poor user experience.

[0042] Based on this, this application provides a support structure that reduces drawer sliding friction and restricts drawer wobbling, enabling the drawer to slide smoothly and thus improving the user experience. It is understood that the support structure provided in this application can be used not only to support drawers but also to support any moving parts that users require to be pulled out; this application makes no limitation on this.

[0043] The supporting structure provided in this application will now be described in conjunction with the accompanying drawings.

[0044] See Figures 1 to 2 This application provides a support structure 100, including a support base 110 and a guide base 120. The support base 110 has a top end 111 and a bottom end 112 opposite to the top end 111. The top end 111 has a support portion 1111, and the support portion 1111 has a first support side 1111a and a second support side 1111b opposite to each other. The guide base 120 has a first guide portion 121 connecting the first support side 1111a and the second support side 1111b. In the direction from the bottom end 112 to the top end 111, the first guide portion 121 protrudes from the support portion 1111 to cooperate with the support portion 1111 to form a support groove 130. The first guide portion 121 has a first arcuate convex surface 1211 protruding into the support groove 130 on one side of the support groove 130.

[0045] Specifically, the top end 111 and bottom end 112 of the support base 110 can be spaced apart in the vertical direction shown in the figure, with the top end 111 of the support base 110 located at the top and the bottom end 112 of the support base 110 located at the bottom. The bottom wall of the drawer can press against the support portion 1111 of the top end 111 to support the drawer through the support portion 1111, while reducing the contact area between the top end 111 and the drawer, thereby reducing the sliding friction of the drawer. The first support side 1111a and the second support side 1111b of the support portion 1111 can be spaced apart in the front-back direction shown in the figure, with the first support side 1111a located at the rear and the second support side 1111b located at the front. The drawer can slide in the direction from the first support side 1111a to the second support side 1111b to open the storage space, and the drawer can also slide in the direction from the second support side 1111b to the first support side 1111a to close the storage space.

[0046] The first guide portion 121 of the guide seat 120 is connected between the first support side 1111a and the second support side 1111b, and the first guide portion 121 protrudes upward from the support portion 1111, so that the first guide portion 121 and the support portion 1111 can cooperate to form a support groove 130. With this configuration, the support portion 1111 can be used to restrict the drawer from moving downward in the vertical direction, and the first guide portion 121 can be used to restrict the drawer from swinging in the horizontal direction, thereby preventing the drawer from shaking within the support groove 130.

[0047] Meanwhile, the first guide portion 121 also has a first arc-shaped convex surface 1211 on the side facing the support groove 130, and the first arc-shaped convex surface 1211 protrudes into the support groove 130. This arrangement allows the drawer to press against the first arc-shaped convex surface 1211, forming a point / line contact, reducing the contact area between the drawer and the first guide portion 121 within the support groove 130, thereby reducing sliding friction and thus reducing the drawer's sliding resistance. Furthermore, the protrusion of the first arc-shaped convex surface 1211 into the support groove 130 reduces the gap between the drawer and the first guide portion 121, preventing the drawer from swaying left and right within the support groove 130, thus improving the smoothness of the drawer's sliding and enhancing the user experience.

[0048] Thus, the support structure 100 provided in this application can form a support groove 130 by cooperating with the support portion 1111 and the first guide portion 121, so that the drawer can slide along the support groove 130. At the same time, this application also provides a first arc-shaped convex surface 1211 protruding into the support groove 130 on the side of the first guide portion 121 facing the support groove 130, so as to reduce the sliding friction between the drawer and the support groove 130 by using the first arc-shaped convex surface 1211, and can also reduce the gap between the drawer and the inner wall of the support groove 130 by using the first arc-shaped convex surface 1211, so as to prevent the drawer from swinging left and right in the support groove 130, thereby improving the smoothness of the drawer's sliding and thus improving the user experience.

[0049] See Figures 1 to 3 In one embodiment, to further reduce the sliding friction between the drawer and the support structure 100, the support portion 1111 is provided with a second arc-shaped convex surface 1111c protruding into the support groove 130 on one side of the support groove 130, and the height of the second arc-shaped convex surface 1111c does not exceed the first guide portion 121 in the direction from the bottom end 112 to the top end 111.

[0050] Understandably, the second arc-shaped convex surface 1111c allows the drawer to form a point / line contact with the support portion 1111, thereby reducing the contact area between the drawer and the support portion 1111 and thus reducing the sliding friction between them. This arrangement, utilizing the cooperation between the first arc-shaped convex surface 1211 and the second arc-shaped convex surface 1111c, reduces the sliding friction of the drawer within the support groove 130, thereby reducing sliding resistance and improving sliding smoothness.

[0051] It should be noted that the curvature of the first arc-shaped convex surface 1211 can be along... Figure 3 Extending in the front-to-back direction, and / or, the curvature of the first arcuate convex surface 1211 can also be along... Figure 3 The extension in the vertical direction is not limited in this application. The curvature of the second arc-shaped convex surface 1111c can extend along... Figure 3Extending in the front-back direction, and / or, the curvature of the second arcuate convex surface 1111c can also be along... Figure 3 The application does not restrict the extension in the left or right direction.

[0052] See Figures 1 to 3 In one embodiment, the top end 111 is further provided with a limiting part 1112 connected to the first support side 1111a, and in the direction from the top end 111 to the bottom end 112, the limiting part 1112 is lower than the support part 1111 to form a limiting groove 140 communicating with the support groove 130.

[0053] It should be noted that the limiting part 1112 is used to limit the movement distance of the drawer in the direction from the first support side 1111a to the second support side 1111b. Understandably, the bottom wall of the drawer is usually provided with a limiting block. During the sliding of the drawer in the direction from the first support side 1111a to the second support side 1111b, when the limiting block of the drawer bottom wall moves into the limiting groove 140, since the support part 1111 is higher than the limiting part 1112, the support part 1111 can prevent the limiting block of the drawer bottom wall from continuing to move, indicating that the drawer's storage space has been fully opened. During the sliding of the drawer in the direction from the second support side 1111b to the first support side 1111a, the limiting block of the drawer bottom wall moves out of the limiting groove 140, allowing the drawer to close its storage space.

[0054] See Figures 1 to 3 In one embodiment, the guide seat 120 is further provided with a second guide portion 122, which is connected to one end of the first guide portion 121 located on the first support side 1111a, and the second guide portion 122 protrudes at least from the limiting portion 1112 in the direction from the bottom end 112 to the top end 111.

[0055] It should be noted that the second guide part 122 protrudes from the limiting part 1112, which can prevent the limiting block of the drawer bottom wall from swinging left and right in the limiting groove 140, thereby avoiding the limiting block of the drawer bottom wall from dislodging from the limiting groove 140 and causing the limiting to fail.

[0056] Furthermore, the height of the second guide portion 122 and the first guide portion 121 can be set to be the same to make the structure of the guide seat 120 aesthetically pleasing. At the same time, the first arc-shaped convex surface 1211 protrudes only from the first guide portion 121, which can reduce the contact between the drawer and the second guide portion 122, thereby reducing the sliding friction of the drawer and allowing the drawer to slide smoothly.

[0057] See Figure 2 and Figure 3In one embodiment, the support portion 1111 is further provided with a third support side 1111d connected between the first support side 1111a and the second support side 1111b and disposed opposite to the first guide portion 121. In the direction from the first guide portion 121 to the third support side 1111d, the support portion 1111 is further provided with a third arcuate convex surface protruding from the third support side 1111d.

[0058] It should be noted that the third arc-shaped convex surface is provided on the third support side 1111d, which can... Figure 3 The dimensions of the support portion 1111 are increased in the left-right direction, thereby giving the drawer a larger load-bearing surface in the left-right direction. This design can both prevent the drawer from detaching from the support groove 130 and causing it to derail using the third arc-shaped convex surface, and also distribute the support load of the support portion 1111 on the drawer using the third arc-shaped convex surface, thereby improving the support performance of the support structure 100 on the drawer.

[0059] See Figure 3 and Figure 4 In one embodiment, to facilitate the installation of the support structure 100, the support base 110 is also provided with a connecting portion 113 connecting the top end 111 and the bottom end 112.

[0060] Understandably, drawers typically slide along support rails. The connecting portion 113 of the support structure 100 can connect with the support rail, allowing the support structure 100 to engage with the support rail and thus facilitating the drawer's sliding along the support rail. This design reduces sliding friction between the drawer and the support rail when the drawer slides on the support rail equipped with the support structure 100, while also preventing the drawer from deviating from the rail, thereby achieving smooth sliding of the drawer along the support rail and improving the user experience.

[0061] Understandably, the connecting part 113 can be connected and fixed to the support rail by means of threaded connection, adhesive connection or welding, etc., and this application does not impose any restrictions.

[0062] See Figure 3 and Figure 4 To improve the connection stability between the support structure 100 and the support rail, the support base 110 is also provided with at least one positioning part connected to the connecting part 113. In the direction from the third support side 1111d to the first guide part 121, at least one positioning part protrudes from the connecting part 113.

[0063] Understandably, at least one positioning part can increase the connection area between the support structure 100 and the support rail, thereby improving the connection stability between the support structure 100 and the support rail.

[0064] As an example, at least one positioning part includes a first positioning part 114, and the support base 110 is provided with a connecting hole 116 that passes through the connecting part 113 and the first positioning part 114 in sequence. The connecting hole 116 can be used to install a fastener 400. It should be noted that the first positioning part 114 is along... Figure 4 The connecting part 113 protrudes from left to right, which increases the connection area between the support structure 100 and the support rail. At the same time, fasteners such as screws or bolts can be installed in the connecting hole 116 of the support structure 100 to further fix the support structure 100 and the support rail, thereby improving the connection reliability.

[0065] As an example, at least one positioning part includes a second positioning part 115. The second positioning part 115 is provided with a positioning groove 115a in the direction from the bottom end 112 to the top end 111. A plug-in component that mates with the positioning groove 115a can be provided on the support rail to achieve positioning of the support structure 100 in the vertical direction, so as to prevent the support structure 100 from being squeezed when the drawer slides, causing the support structure 100 to tilt, thereby ensuring that the drawer can slide stably.

[0066] It should be noted that the support structure 100 may include at least one of a first positioning part 114 and a second positioning part 115. The first positioning part 114, in conjunction with the fastener 400, can achieve [positioning along]... Figure 4 The connection and fixation in the left and right directions, the second positioning part 115 and the positioning groove 115a can realize the connection along the left and right directions. Figure 4 The connection in the vertical direction is fixed. In this way, the support structure 100 can be reliably installed on the support rail to ensure that the drawer can slide stably.

[0067] See Figure 3 In one embodiment, at least a portion of the third arcuate convex surface protrudes from the connecting portion 113 in the direction from the first guide portion 121 to the third support side 1111d. This arrangement can both increase the support area of ​​the drawer by utilizing the third arcuate convex surface to prevent the drawer from falling off, and utilize the connecting portion 113 to support the support portion 1111 from below, thereby sharing the pressure load of the drawer on the support portion 1111.

[0068] For ease of understanding, this application also provides a drawer assembly 10 that uses the above-described support structure 100. The drawer assembly 10 provided in this application will be described below.

[0069] See Figures 5 to 8This application provides a drawer assembly 10, including a support rail 200, a drawer 300, and a support structure 100 of any of the above embodiments. At least a portion of the support structure 100 is connected to the support rail 200. A first support side 1111a and a second support side 1111b are disposed opposite to each other along the length direction of the support rail 200, and a top end 111 and a bottom end 112 are disposed opposite to each other along the height direction of the support rail 200. The drawer 300 is provided with a mating rail 310 that is slidably connected to the support rail 200. The mating rail 310 can reciprocate within a support groove 130 along the length direction of the support rail 200, so that the mating rail 310 abuts against a first arcuate convex surface 1211.

[0070] It should be noted that the length direction of the support rail 200 can be along... Figure 5 The support rail is set in the front and rear directions, and its height direction can be along the center. Figure 5 The drawer 300 is positioned vertically. The mating rail 310 of the drawer 300 can abut against the support rail 200 and slide back and forth along the length of the support rail 200. This configuration allows the drawer 300's mating rail 310 to slide within the support groove 130 and abut against the first arc-shaped convex surface 1211 when the support structure 100 is installed on the support rail 200. This reduces sliding friction of the drawer 300's mating rail 310 within the support groove 130. Furthermore, the first arc-shaped convex surface 1211 reduces the gap between the drawer 300 and the first guide portion 121, preventing the drawer 300's mating rail 310 from swaying left or right within the support groove 130, thus preventing the drawer 300 from detaching from the support rail 200 and allowing the drawer 300 to slide smoothly.

[0071] See Figure 5 and Figure 6 In one embodiment, to improve the stability of the support structure 100 installed on the support rail 200, after the support structure 100 and the support rail 200 are connected and fixed by the fastener 400, the portion of the fastener 400 extending out of the connection hole 116 is also equipped with a mating part 500 to seal the end of the fastener 400, preventing the fastener 400 from falling out of the connection hole 116, thereby improving the connection stability between the support structure 100 and the support rail 200. It is understood that the fastener 400 and the mating part 500 can be connected and fixed by means of threaded connection, insertion, adhesive bonding, or welding, etc., and this application does not impose any limitations.

[0072] See Figure 5 and Figure 6 In one embodiment, the support rail 200 is provided with a first mounting groove 210 on the side that abuts against the mating rail 310, the support seat 110 is located in the first mounting groove 210, and the support seat 110 is provided with a second arc-shaped convex surface 1111c. At least a portion of the second arc-shaped convex surface 1111c protrudes out of the first mounting groove 210 in the direction from the bottom end 112 to the top end 111.

[0073] This configuration allows the support rail 200 to form a surrounding support for the support base 110 via the first mounting groove 210, thereby increasing the support strength of the support base 110. Simultaneously, the second arc-shaped convex surface 1111c protrudes upwards from the first mounting groove 210, allowing the mating rail 310 of the drawer 300 to press against the second arc-shaped convex surface 1111c. This reduces sliding friction between the mating rail 310 of the drawer 300 and the support rail 200, thus reducing the sliding resistance of the drawer 300. Furthermore, the arc-shaped structure of the second arc-shaped convex surface 1111c provides good structural strength, and it also satisfies the support requirements for the mating rail 310.

[0074] See Figure 5 and Figure 6 In one embodiment, along the length of the support rail 200, the support rail 200 is provided with a first support surface 220 and a second support surface 230 located on both sides of the first mounting groove 210. The first support surface 220 is disposed near the first support side 1111a, and the second support surface 230 is disposed near the second support side 1111b. In the direction from the bottom end 112 to the top end 111, the second support side 1111b is flush with the second support surface 230, and the second arc-shaped convex surface 1111c is higher than the second support surface 230.

[0075] With this design, when the drawer 300 contains a large amount of stored items, resulting in significant pressure on the second arc-shaped convex surface 1111c, the second arc-shaped convex surface 1111c may be deformed by downward pressure, meaning its curvature is flattened. At this time, because the second support side 1111b is flush with the second support surface 230, the deformed second arc-shaped convex surface 1111c can be flush with the second support surface 230. This allows the second arc-shaped convex surface 1111c and the second support surface 230 to cooperate and form a single support surface. The second support surface 230 then shares the pressure exerted by the drawer 300 on the second arc-shaped convex surface 1111c, thus providing adequate support for the drawer 300 and enabling it to slide smoothly.

[0076] Furthermore, the first support surface 220 is positioned lower than the second support surface 230, which prevents the drawer 300 from pressing against the first support surface 220 and reduces the sliding friction of the drawer 300. In addition, the first support surface 220 and the first support side 1111a are spaced apart from each other, which also allows for the provision of deformation space for the second arc-shaped convex surface 1111c.

[0077] For ease of understanding, this application also provides a refrigerator 1 that uses the above-described drawer assembly 10. The refrigerator 1 provided by this application will be described below.

[0078] See Figures 9 to 13This application provides a refrigerator 1, including an inner liner 20 and a drawer assembly 10 of any of the above embodiments. The inner liner 20 is provided with a cooling compartment 21, the drawer assembly 10 is located in the cooling compartment 21, and the support rail 200 is connected to the inner liner 20.

[0079] It should be noted that users can store food or items requiring refrigeration / freezing in the cooling compartment 21 of refrigerator 1. The height of the inner liner 20 can be adjusted along... Figure 9 The vertical setting in the middle, the depth direction of the inner liner 20 can be along... Figure 9 The inner liner 20 is oriented in the front-to-back direction, and its width can be oriented in the left-to-right direction as shown in the figure. When the support rail 200 is installed to the inner liner 20, its length can be oriented along the depth of the inner liner 20, allowing the drawer 300 to slide back and forth along the depth of the inner liner 20 to open or close its storage space. In this way, the drawer 300 in the refrigerator compartment 21 can slide smoothly in conjunction with the support structure 100, improving user satisfaction with the refrigerator 1.

[0080] See Figures 10 to 13 In one embodiment, the support rail 200 protrudes from the inner wall of the inner liner 20. The inner liner 20 is also provided with a second mounting groove 22 that communicates with the refrigeration chamber 21. The guide seat 120 is located in the second mounting groove 22, and the first arc-shaped convex surface 1211 protrudes from the second mounting groove 22.

[0081] It should be noted that the second mounting groove 22 is used to accommodate the guide seat 120, and allows the first arc-shaped convex surface 1211 to be able to move along the guide seat 120. Figure 13 The drawer 300 is designed to protrude from the inner wall of the inner liner 20 in a right-to-left direction. This design allows the drawer 300's mating rail 310 to press against the first arc-shaped convex surface 1211, reducing contact with the inner wall of the inner liner 20. This reduces sliding friction between the drawer 300 and the inner liner 20 and also prevents the drawer 300 from breaking the inner liner 20 during sliding.

[0082] See Figures 10 to 13 In one embodiment, the support rail 200 and the inner liner 20 can be integrally formed, and this application does not impose any restrictions.

[0083] See Figure 13When the support structure 100 is connected to the inner liner 20, a fastener 400 can be installed in the connection hole 116 of the support structure 100. The fastener 400 can pass through the support structure 100 and the inner liner 20 in sequence, with at least a portion of the fastener 400 exposed to the outer wall of the inner liner 20. Furthermore, a mating part 500 connected to the fastener 400 can be installed on the outer wall of the inner liner 20, with the mating part 500 and the fastener 400 located on opposite sides of the inner liner 20, thereby fixing the support structure 100 to the inner liner 20. This design facilitates the disassembly and replacement of the support structure 100, reducing maintenance costs.

[0084] See Figure 12 An avoidance groove 240 is also provided in the first mounting groove 210 of the support rail 200. The positioning part of the support structure 100 can be set one-to-one with the avoidance groove 240 so that the support structure 100 can be stably installed on the support rail 200, and the support structure 100 is prevented from tilting relative to the support rail 200 due to the sliding of the drawer 300, thereby ensuring that the drawer 300 can slide smoothly.
