Description

Technical Field

[0001] This utility model relates to the field of storage device technology, and in particular to a storage device. Background Technology

[0002] As an important storage device, the design of the drawer slide system of a refrigerator directly affects the user experience.

[0003] Traditional drawer slides mostly use separate metal slides. These slide smoothly and won't fall off, providing a better user experience. However, they require screws and other fasteners to install separately onto the drawer and cabinet, making the structure more complex and less suitable for most users. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a storage device that ensures smooth drawer movement and prevents the support components from easily falling off the slide rails.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] Please see Figures 1 to 3 This application provides a storage device 100, which can be a refrigerator, cabinet or other storage device 100. For ease of description, the following explanation will take a refrigerator as an example of the storage device 100.

[0039] The storage device 100 includes a housing 110, a drawer 130, and a support assembly 150.

[0040] The box body 110 may have one or more storage compartments, and each storage compartment may have at least one drawer 130.

[0041] As an example, taking a refrigerator as an example, the cabinet 110 may be provided with storage compartments such as a refrigerator compartment, a freezer compartment, and an ice-making compartment. At least one of the storage compartments such as the refrigerator compartment, freezer compartment, and ice-making compartment is provided with at least one drawer 130.

[0042] The cabinet 110 includes a cabinet body and a slide rail 113. The cabinet body has a receiving cavity 111, which has an open opening 1110. The drawer 130 can move from the opening 1110 into the receiving cavity 111 to close the drawer 130 (e.g., ...). Figure 1 (As shown), it can also be moved from inside the receiving cavity 111 towards the cavity opening 1110 until it is partially outside the receiving cavity 111 to open the drawer 130 (as shown). Figure 2 (As shown).

[0043] Understandably, the accommodating cavity 111 can refer to the aforementioned storage chamber, such as a refrigeration chamber, a freezing chamber, or an ice-making chamber.

[0044] The inner wall of the accommodating cavity 111 is provided with two opposing slide rails 113, that is, the accommodating cavity 111 is provided with a slide rail 113 on the inner wall on the left and right sides along the moving direction of the drawer 130.

[0045] Drawer 130 includes drawer body 131 and slide bar 133. The outer wall of drawer body 131 is provided with two opposing slide bars 133, that is, a slide bar 133 is provided on the left and right sides of drawer body 131 along the moving direction.

[0046] Each slide bar 133 is slidably connected to a slide rail 113 via at least one support component 150. In this way, the support component 150 can be supported between the drawer 130 and the cabinet 110, thereby improving the sliding friction generated by the direct contact between the slide bar 133 and the inner wall of the slide rail 1130, and helping the drawer 130 to move more smoothly.

[0047] At least one support component 150 may refer to one support component 150, two support components 150, three support components 150 or other number of support components 150. When the slide bar 133 is slidably connected to a slide rail 113 by two or more support components 150, two adjacent support components 150 may be distributed at intervals along the length direction of the slide groove 1130, and their specific positions can be set according to requirements.

[0048] Each slide rail 113 is provided with a slide groove 1130, and the slide bar 133 is at least partially inserted in the slide groove 1130 and can move along the length of the slide groove 1130, so that the drawer 130 can move back and forth in the slide groove 1130 relative to the box body 110, making it easy to open or close the drawer 130.

[0049] Specifically, each component 150 includes a retaining bracket 151 and a rolling element 159. The retaining bracket 151 is partially inserted between the inner wall of the slide bar 133 and the groove 1130. The rolling element 159 is rotatably connected to the portion of the retaining bracket 151 located between the inner wall of the slide bar 133 and the groove 1130. The rolling element 159 can roll and contact the inner wall of the groove 1130 and the slide bar 133 respectively. The rolling element 159 is configured to roll as the drawer 130 moves, and drive the retaining bracket 151 to move within the groove 1130 and the retaining groove 1150 along the direction of movement of the drawer 130. In this way, the rolling element 159 can roll and contact the inner wall of the slide bar 133 and the groove 1130, which helps to prevent the slide bar 133 from rolling. The contact friction between the inner wall of the slide rail 1130 and the slide rail 133 reduces the sliding friction when the drawer 130 moves, which helps the drawer 130 move more smoothly. In addition, the support component 150 can move with the drawer 130, which helps to adjust the support position of the rolling element 159 between the slide rail 133 and the slide rail 1130 to better support the drawer 130 and make the drawer 130 move more stably. Compared with the method of setting a separate metal slide rail between the drawer and the box in the related technology, in the storage device 100 provided in this application embodiment, only a movable support component 150 is needed between the drawer 130 and the box 110 to ensure the smoothness and stability of the drawer 130's movement, and the manufacturing cost is lower.

[0050] The limiting bracket 151 is snapped onto the slide rail 113 from the side facing or away from the receiving cavity 111. This allows the limiting bracket 151 to be installed and removed only from the side of the slide rail 113. When the drawer 130 is pulled out from the receiving cavity 111, the limiting bracket 151 is less likely to detach from the slide rail 113, which helps the support assembly 150 to support the drawer 130 more stably. In addition, compared with the related technology, which requires the metal split slide rail to be installed on the box and drawer separately with screws and other fasteners, the embodiment of this application can directly snap the limiting bracket 151 onto the slide rail 113 from the side, which is more convenient to install and the drawer 130 moves smoothly and stably.

[0051] As an example, the slide rail 113 may have a first slot on the side opposite to the receiving cavity 111, and the limiting member may be inserted and installed on the slide rail 113 through the first slot.

[0052] As another example, the slide rail 113 may be provided with a second slot on the side facing the receiving cavity 111, and the limiting member can be inserted and installed on the slide rail 113 from the second slot.

[0053] In some embodiments, the slide rail 113 may also be provided with a limiting groove 1150. The slide groove 1130 and the limiting groove 1150 may be interconnected, and the limiting groove 1150 and the slide groove 1130 may be recessed on opposite sides of the slide rail 113. The limiting bracket 151 may also be partially inserted into the limiting groove 1150. The rolling element 159 is configured to roll as the drawer 130 moves, and drive the limiting bracket 151 to move in the slide groove 1130 and the limiting groove 1150 along the moving direction of the drawer 130.

[0054] As an example, the slide groove 1130 can extend through the slide rail 113 along its length, and the length of the slide rail 113 is roughly along the moving direction of the drawer 130. The limiting groove 1150 can extend in the same direction as the slide groove 1130, and the extension length of the limiting groove 1150 can be less than the extension length of the slide groove 1130.

[0055] The limiting groove 1150 may include a first groove 1151. The first groove 1151 may be located on the side of the slide rail 113 opposite to the receiving cavity 111. The first groove 1151 may form an installation opening for the limiting frame 151 to be sequentially inserted and installed in the limiting groove 1150 and the slide groove 1130. That is, the limiting frame 151 can be inserted and installed in the limiting groove 1150 and the slide groove 1130 from the first groove 1151, which helps to reduce the installation difficulty of the limiting frame 151 and improve the assembly efficiency.

[0056] Understandably, the first card slot in the above embodiment can be the first slot 1151 in this embodiment.

[0057] In some embodiments, the continuous extension length of the slide groove 1130 and the continuous extension length of the slide bar 133 can both be greater than half the concave depth of the receiving cavity 111 from the cavity opening 1110 into the housing 110. This ensures that the bottom and top of the slide bar 133, the top wall 1135 and the side wall 1137 of the slide groove 1130 can all have a sufficiently large extension length to provide a sufficiently long rolling surface for the rolling element 159. This helps the rolling element 159 to have a sufficient rolling stroke so that the drawer 130 can move stably to open and close.

[0058] In some embodiments, the two opposite inner sidewalls of the accommodating cavity 111 may be integrally formed with a slide rail 113, thereby reducing the manufacturing cost of the housing 110 and reducing the number of parts of the storage device 100, which helps to simplify the assembly process of the storage device 100.

[0059] As an example, both the box body and the slide rail 113 can be made of plastic, and the box body and the slide rail 113 can be vacuum-formed into a single structure. Understandably, the box body and the slide rail 113 can also be made of other materials, and the box body and the slide rail 113 can also be processed using other single-piece molding processes.

[0060] Wherein, the limiting groove 1150 can be located on the side of the slide rail 1130 opposite to the receiving cavity 111, and the first slot 1151 can be provided on the side of the slide rail 113 opposite to the receiving cavity 111.

[0061] In some embodiments, the two opposite outer walls of the drawer body 131 may be integrally formed with a slide bar 133, thereby reducing the manufacturing cost of the drawer 130 and reducing the number of parts of the storage device 100, which helps to simplify the assembly process of the storage device 100.

[0062] As an example, both the drawer body 131 and the slide rail 133 can be made of plastic, and the drawer body 131 and the slide rail 133 can be vacuum-formed or injection-molded into a single structure. Understandably, the drawer body 131 and the slide rail 133 can also be made of other materials, and thus the drawer body 131 and the slide rail 133 can also be manufactured using other single-piece molding processes.

[0063] In some embodiments, a first limiting wall 1153 may be provided at one end of the limiting groove 1150 near the cavity 1110. The first limiting wall 1153 can be used to limit the travel of the limiting frame 151 toward the cavity 1110, thereby limiting the limiting frame 151 and the rolling element 159 on the slide rail 113. This helps to prevent the limiting frame 151 and the rolling element 159 from disengaging from the side of the cavity 1110 onto the slide rail 113. The rolling element 159 can support the drawer 130 more stably, further ensuring the stability of the drawer 130's movement.

[0064] As an example, when the drawer 130 needs to be cleaned, it can be moved from the receiving cavity 111 toward the cavity opening 1110 until it is disengaged from the receiving cavity 111, thus removing the drawer 130 from the housing 110. At this time, the first limiting wall 1153 can block the limiting bracket 151 to restrict the limiting bracket 151 onto the slide rail 113, thereby preventing the limiting bracket 151 and the rolling element 159 from disengaging from the slide rail 113 along with the drawer 130, and avoiding the need for the user to repeatedly install the support component 150. When the drawer 130 needs to be reinstalled into the housing 110, it is only necessary to insert the slide bars 133 on both sides of the drawer 130 into the end of the slide groove 1130 near the cavity opening 1110. This convenient installation ensures the smoothness and stability of the drawer 130's movement.

[0065] In some embodiments, a second limiting wall 1155 may be provided at the end of the limiting groove 1150 away from the cavity 1110. The second limiting wall 1155 can be used to limit the travel of the limiting frame 151 away from the cavity 1110, which helps to prevent the limiting frame 151 and the rolling element 159 from disengaging from the end of the slide rail 113 away from the cavity 1110. The rolling element 159 can support the drawer 130 more stably, further ensuring the stability of the movement of the drawer 130.

[0066] The first limiting wall 1153 and the second limiting wall 1155 can be spaced apart from each other along the length direction of the limiting groove 1150, and the support component 150 can move between the first limiting wall 1153 and the second limiting wall 1155. The first limiting wall 1153 and the second limiting wall 1155 can be the two inner walls of the limiting groove 1150 that are opposite each other in the extension direction.

[0067] Please see Figures 2 to 4 In some embodiments, the slide rail 113 may also be provided with a first slot 1170. The first slot 1170 may be provided between the slide groove 1130 and the limiting groove 1150 and connect the slide groove 1130 and the limiting groove 1150. In this way, the first slot 1170 can provide the limiting frame 151 with an opening for passing through the limiting groove 1150 into the slide groove 1130.

[0068] Specifically, the limiting frame 151 may include a first transverse support arm 1510, and the rolling element 159 may include a first rolling element 1590. The first transverse support arm 1510 can extend laterally from the limiting groove 1150, pass through the first slot 1170, and pass between the bottom of the slide bar 133 and the inner wall of the slide groove 1130. The first rolling element 1590 is rotatably connected to the first transverse support arm 1510. The inner wall of the first slot 1170 along the vertical groove can also limit the vertical movement of the first transverse support arm 1510, which helps the first transverse support arm 1510 move more stably, reduces the impact of the vertical movement of the first transverse support arm 1510 on the first rolling element 1590, and helps the first rolling element 1590 roll more smoothly.

[0069] As an example, the first horizontal support arm 1510 can be spaced apart from the inner wall of the slide groove 1130 and from the bottom of the slide bar 133 to reduce contact friction. When the drawer 130 shakes up and down, the vertical inner wall of the first slot 1170 can abut against the first horizontal support arm 1510 to limit the vertical travel of the first horizontal support arm 1510. The first horizontal support arm 1510 can be plate-shaped and can be parallel to or inclined relative to the horizontal plane.

[0070] The first rolling element 1590 can rollably contact the bottom of the slide bar 133 and the inner wall of the slide groove 1130, respectively. This allows the first rolling element 1590 to be supported between the bottom of the slide bar 133 and the inner wall of the slide groove 1130, helping to reduce friction between them and improving the smoothness of the drawer 130's movement. Specifically, the top of the first rolling element 1590 can rollably contact the bottom of the slide bar 133, and the bottom of the first rolling element 1590 can rollably contact the inner wall of the slide groove 1130.

[0071] The first rolling element 1590 can be configured to roll as the drawer 130 moves, and drive the first transverse support arm 1510 to move in the slide groove 1130, the first slot 1170 and the limiting groove 1150 along the moving direction of the drawer 130.

[0072] In some embodiments, the slide rail 113 may also be provided with a second slot 1190. The second slot 1190 may be located between the slide groove 1130 and the limiting groove 1150, and the second slot 1190 may be located above the first slot 1170. The second slot 1190 may connect the slide groove 1130 and the limiting groove 1150. In this way, the second slot 1190 may also provide a passage for the limiting frame 151 to pass through the limiting groove 1150 into the slide groove 1130.

[0073] Specifically, the limiting frame 151 may further include a second transverse support arm 1530, and the rolling element 159 may further include a second rolling element 1610. The second transverse support arm 1530 can extend laterally from the limiting groove 1150, pass through the second slot 1190, and pass between the top of the slide bar 133 and the inner wall of the slide groove 1130. The second rolling element 1610 is rotatably connected to the second transverse support arm 1530. The inner wall of the second slot 1190 along the vertical groove can also limit the vertical movement of the second transverse support arm 1530, which helps the second transverse support arm 1530 move more stably, reduces the impact of the vertical movement of the second transverse support arm 1530 on the second rolling element 1610, and helps the second rolling element 1610 roll more smoothly.

[0074] As an example, the second horizontal support arm 1530 can be spaced apart from the inner wall of the slide rail 1130 and from the top of the slide bar 133 to reduce contact friction. When the drawer 130 shakes up and down, the vertical inner wall of the second slot 1190 can abut against the second horizontal support arm 1530 to limit the vertical travel of the second horizontal support arm 1530. The second horizontal support arm 1530 can be plate-shaped and can be parallel to or inclined relative to the horizontal plane.

[0075] The second rolling element 1610 can rollably contact the top of the slide bar 133 and the inner wall of the slide groove 1130, respectively, so that the first rolling element 1590 can be supported between the top of the slide bar 133 and the inner wall of the slide groove 1130, which helps to reduce the contact friction between the top of the slide bar 133 and the inner wall of the slide groove 1130, and improves the smoothness of the drawer 130 movement. That is, the top of the second rolling element 1610 can rollably contact the inner wall of the slide groove 1130, and the bottom of the first rolling element 1590 can rollably contact the top of the slide bar 133.

[0076] In addition, the first roller 1590 and the second roller 1610 are supported at the bottom and top of the slide bar 133, respectively, which helps the drawer 130 move more smoothly and stably.

[0077] The second rolling element 1610 is configured to roll as the drawer 130 moves, and drive the second transverse support arm 1530 to move in the slide groove 1130, the second slot 1190 and the limiting groove 1150 along the moving direction of the drawer 130.

[0078] It should be noted that the first slot 1170 and the second slot 1190 can be distributed at intervals along the vertical direction, and the first horizontal support arm 1510 and the second horizontal support arm 1530 can be two separate structural components, or they can be connected together by other structures.

[0079] Specifically, in some embodiments, the limiting frame 151 may further include a vertical support arm 1550, which may be disposed within the limiting groove 1150.

[0080] The first horizontal support arm 1510 extends laterally from the bottom end of the vertical support arm 1550 to pass through the first slot 1170 and between the bottom of the slide bar 133 and the inner wall of the slide groove 1130. The second horizontal support arm 1530 extends laterally from the top end of the vertical support arm 1550 to pass through the second slot 1190 and between the top of the slide bar 133 and the inner wall of the slide groove 1130. In this way, the vertical support arm 1550 can connect the first horizontal support arm 1510 and the second horizontal support arm 1530, so that the first horizontal support arm 1510 and the second horizontal support arm 1530 can move synchronously. The first rolling element 1590 and the second rolling element 1610 can simultaneously drive the limit frame 151 to move when rolling, which helps the limit frame 151 to move more smoothly and stably, and helps the drawer 130 to move more smoothly and stably. In addition, the first roller 1590 and the second roller 1610 can support the slide bar 133 at approximately the same position on the top and bottom of the slide bar 133, further making the drawer 130 move more smoothly.

[0081] As an example, the vertical support arm 1550 is movably disposed within the limiting groove 1150. The vertical support arm 1550 can be spaced apart from the inner wall of the limiting groove 1150 to reduce contact friction. The vertical support arm 1550 can be plate-shaped and can be parallel to or inclined relative to a vertical plane. The first limiting baffle 1153 can be used to limit the travel of the entire limiting frame 151 toward the cavity opening 1110 by limiting the travel of at least one of the vertical support arm 1550, the first transverse support arm 1510, and the second transverse support arm 1530 toward the cavity opening 1110. The second limiting baffle 1155 can limit the travel of at least one of the vertical support arm 1550, the first transverse support arm 1510, and the second transverse support arm 1530 away from the cavity opening 1110, thereby limiting the travel of the entire limiting frame 151 away from the cavity opening 1110.

[0082] In some embodiments, the chute 1130 may include a second groove 1131, a bottom wall 1133, a top wall 1135, and a side wall 1137.

[0083] The first slot 1151 and the second slot 1131 can be respectively located on opposite sides of the slide rail 113, that is, the first slot 1151 can be located on the side of the slide rail 113 facing the receiving cavity 111.

[0084] The sidewall 1137 of the groove and the second groove opening 1131 can be arranged opposite each other at intervals.

[0085] As an example, the slot sidewall 1137 and the second slot opening 1131 can be distributed along the horizontal direction X. The drawer body 131 and the slot sidewall 1137 can be located on opposite sides of the second slot opening 1131 along the horizontal direction X. The first slot opening 1151 and the second slot opening 1131 can be located on opposite sides of the slot sidewall 1137 along the horizontal direction X. The first slot 1170 and the second slot 1190 can both penetrate the slot sidewall 1137 to connect the sliding groove 1130 and the limiting groove 1150, respectively.

[0086] The top wall 1135 and the bottom wall 1133 of the trough can extend from the top and bottom of the second trough opening 1131 to the side wall 1137 of the trough, respectively.

[0087] As an example, the top wall 1135 and the bottom wall 1133 of the tank can be spaced apart from each other in the vertical direction Y, and the top wall 1135 can be located above the bottom wall 1133.

[0088] The slide bar 133 can be inserted into the slide groove 1130 at least partially through the second groove 1131. There can be gaps between the top wall 1135, bottom wall 1133, and side wall 1137 of the groove and the slide bar 133 to reduce sliding friction.

[0089] The first lateral support arm 1510 can extend laterally from the limiting groove 1150 and pass through the first slot 1170 and between the bottom of the slide bar 133 and the bottom wall 1133 of the slot.

[0090] As an example, the first lateral support arm 1510 can extend laterally from the limiting groove 1150, pass through the first slot 1170, and pass through the gap between the bottom of the slide bar 133 and the bottom wall 1133 of the slot. The first lateral support arm 1510 can be spaced apart from the inner wall of the limiting groove 1150 and from the inner wall of the first slot 1170, thereby reducing sliding friction and helping the first lateral support arm 1510 to move more smoothly, which in turn helps the drawer 130 to move more smoothly.

[0091] The second lateral support arm 1530 can extend laterally from the limiting groove 1150 and pass through the second slot 1190 and between the top of the slide bar 133 and the top wall 1135 of the slot.

[0092] As an example, the second lateral support arm 1530 can extend laterally from the limiting groove 1150, pass through the second slot 1190, and pass through the gap between the top of the slide bar 133 and the top wall 1135 of the slot. The second lateral support arm 1530 can be spaced apart from the inner wall of the limiting groove 1150 and from the inner wall of the second slot 1190, thereby reducing sliding friction and helping the second lateral support arm 1530 to move more smoothly, which in turn helps the drawer 130 to move more smoothly.

[0093] In some embodiments, the first transverse support arm 1510 may be provided with a first limiting through hole 1511 and a first opening 1513.

[0094] The first opening 1513 can be located at the edge of the first transverse support arm 1510 facing the receiving cavity 111, and the first opening 1513 can be connected to the first limiting through hole 1511. The first rolling element 1590 is rotatably fitted into the first limiting through hole 1511. Thus, when the first rolling element rolls between the bottom wall 1133 of the groove and the bottom of the slide groove 1130, the first rolling element 1590 can push against the hole wall of the first limiting through hole 1511 to drive the first transverse support arm 1510 to move. The first transverse support arm 1510 can limit the position of the first rolling element 1590, which helps the first rolling element 1590 to roll more stably.

[0095] In some embodiments, the number of first openings 1513, first limiting through holes 1511, and first rolling elements 1590 can be multiple, and the first openings 1513, first limiting through holes 1511, and first rolling elements 1590 can correspond one-to-one. Multiple first openings 1513 can be distributed along the length direction of the slide groove 1130 on the edge of the first transverse support arm 1510 facing the receiving cavity 111, and multiple first limiting through holes 1511 can also be distributed along the length direction of the slide groove 1130 on the first transverse support arm 1510. Each first limiting through hole 1511 can be fitted with a rotatable first rolling element 1590, so that multiple first rolling elements 1590 can be supported between the bottom of the slide bar 133 and the bottom wall 1133 of the groove, which helps to support the drawer 130 more stably and reduce the possibility of the drawer 130 tipping over.

[0096] In some embodiments, the second lateral support arm 1530 is provided with a second limiting through hole 1531 and a second opening 1533.

[0097] The second opening 1533 can be located at the edge of the second transverse support arm 1530 facing the receiving cavity 111, and the second opening 1533 can connect to the second limiting through hole 1531. The second rolling member 1610 is rotatably engaged in the second limiting through hole 1531. Thus, when the second rolling member rolls between the top wall 1135 of the groove and the top of the slide groove 1130, the second rolling member 1610 can push against the hole wall of the second limiting through hole 1531 to drive the second transverse support arm 1530 to move. The second transverse support arm 1530 can limit the position of the second rolling member 159, which helps the second rolling member 1610 to roll more stably.

[0098] In some embodiments, the number of second openings 1533, second limiting through holes 1531, and second rolling elements 1610 can be multiple, and the second openings 1533, second limiting through holes 1531, and second rolling elements 1610 can correspond one-to-one. Multiple second openings 1533 can be distributed along the length of the slide groove 1130 on the edge of the second transverse support arm 1530 facing the receiving cavity 111. Multiple second limiting through holes 1531 can also be distributed along the length of the slide groove 1130 on one side of the second transverse support arm 1530. Each second limiting through hole 1531 can be fitted with a rotatable second rolling element 1610, so that multiple second rolling elements 1610 can be supported between the top of the slide bar 133 and the top wall 1135 of the groove, which helps to support the drawer 130 more stably and reduces the possibility of the drawer 130 tipping over.

[0099] In some embodiments, the bottom wall 1133 of the groove may be recessed with a first raceway groove 1143, which may extend along the length of the slide groove 1130. The first rolling element 1590 may roll in contact with the inner wall of the first raceway groove 1143. Thus, the first raceway groove 1143 can provide a more accurate raceway for the first rolling element 1590, and the inner wall of the first raceway groove 1143 can limit the position of the first rolling element 1590, which helps the first rolling element 1590 to roll more stably and helps the drawer 130 to move more stably.

[0100] In some embodiments, the slide rail 113 may further include a first locking portion 1210, which extends laterally from the top of the first slot 1170 toward the slide groove 1130 to enclose with the first raceway groove 1143 to form a first locking groove 1250 into which the first rolling member 1590 can be rollably locked and positioned. The first rolling member 1590 may partially protrude from the first locking groove 1250 to rollably contact the bottom of the slide bar 133, thereby allowing the first rolling member 1590 to be rollably locked into the first locking groove 1250, which helps to better limit the rolling position of the first rolling member 1590 and reduce the possibility of the first rolling member 1590 falling out of the first raceway groove 1143.

[0101] Furthermore, since the first rolling element 1590 is rotatably mounted in the first limiting through hole 1511, and the first limiting baffle 1153 can limit the travel of the limiting frame 151 toward the cavity opening 1110, the first limiting baffle 1153 can restrict the limiting frame 151 on the slide rail 113, thereby indirectly restricting the first rolling element 1590 in the first slot 1250, which helps to prevent the first rolling element 1590 from disengaging from the end of the first slot 1250 near the cavity opening 1110. The second limiting wall 1155 can limit the travel of the limiting frame 151 in the direction away from the cavity 1110. The second limiting wall 1155 can also limit the limiting frame 151 on the slide rail 113, thereby indirectly limiting the first rolling element 1590 in the first slot 1250, which helps to prevent the first rolling element 1590 from leaving the first slot 1250 from the end of the first slot 1250 away from the cavity 1110.

[0102] As an example, the first locking part 1210 and the bottom wall 1133 of the groove can be spaced apart. The first locking part 1210 can be connected to the side wall 1137 of the groove. The first locking part 1210 can be located between the bottom wall 1133 of the groove and the bottom of the slide bar 133, and spaced apart from the bottom wall 1133 of the groove and the bottom of the slide bar 133, respectively. The first transverse support arm 1510 can pass through the first locking part 1210 and the bottom wall 1133 of the groove. The side edge of the first locking part 1210 facing the receiving cavity 111 is approximately arc-shaped, and the inner wall of the first raceway groove 1143 is also approximately arc-shaped. The cross-section of the inner wall of the first raceway groove 1143 and the cross-section of the side edge of the first locking part 1210 can fit together with a circle larger than 1 / 2 circle, so that the first locking groove 1250 can lock the first rolling element 1590.

[0103] Understandably, the first slot 1250 also extends along the length of the slide 1130.

[0104] It should be noted that there are multiple installation methods when installing the first rolling element 1590.

[0105] As an example, the plastic deformation of the slide rail 113 can be used to press the first rolling element 1590 into the first slot 1250 from the inside of the slide groove 1130. Then, the first transverse support arm 1510 of the limiting frame 151 can be inserted into the slide groove 1130 so that the first opening 1513 is aligned with the first rolling element 1590. The first transverse support arm 1510 can be pushed to move towards the receiving cavity 111. The plastic deformation of the limiting frame 151 can be used to make the first rolling element 1590 snap into the first limiting through hole 1511 from the first opening 1513.

[0106] As another example, the first transverse support arm 1510 of the limiting frame 151 can be inserted into the slide groove 1130 first, and then the first rolling element 1590 can be pressed from the inside of the slide groove 1130 into the first slot 1250 and the limiting through hole by utilizing the plastic deformation of the slide rail 113 and the limiting frame 151.

[0107] Understandably, when there are multiple first openings 1513, first limiting through holes 1511, and first rolling elements 1590, the above installation method can also be used, and will not be elaborated further.

[0108] In some embodiments, the groove top wall 1135 may be provided with a second raceway groove 1145, which may extend along the length of the slide groove 1130. The second rolling element 1610 may roll in contact with the inner wall of the second raceway groove 1145. Thus, the second raceway groove 1145 can provide a more accurate raceway for the second rolling element 1610, and the inner wall of the second raceway groove 1145 can limit the position of the second rolling element 1610, which helps the second rolling element 1610 to roll more stably and helps the drawer 130 to move more stably.

[0109] In some embodiments, the slide rail 113 further includes a second locking portion 1230, which extends laterally from the bottom of the second slot 1190 toward the slide groove 1130 to enclose with the second raceway groove 1145 to form a second locking groove 1270 for the second rolling member 1610 to be rotatably locked into and positioned. The second rolling member 1610 may partially protrude outside the second locking groove 1270 to rotatably contact the top of the slide bar 133, thereby allowing the second rolling member 1610 to be rotatably locked into the second locking groove 1270, which helps to better limit the rolling position of the second rolling member 1610 and reduce the possibility of the second rolling member 1610 falling out of the second raceway groove 1145.

[0110] Furthermore, since the second rolling element 1610 is rotatably mounted in the second limiting through hole 1531, and the first limiting baffle 1153 can limit the travel of the limiting frame 151 toward the cavity opening 1110, the first limiting baffle 1153 can restrict the limiting frame 151 on the slide rail 113, thereby indirectly restricting the second rolling element 1610 in the second slot 1270, which helps to prevent the second rolling element 1610 from disengaging from the end of the second slot 1270 near the cavity opening 1110. The second limiting wall 1155 can limit the travel of the limiting frame 151 away from the cavity opening 1110. The second limiting wall 1155 can also limit the limiting frame 151 on the slide rail 113, thereby indirectly limiting the second rolling element 1610 in the second slot 1270, which helps to prevent the second rolling element 1610 from leaving the second slot 1270 from the end of the second slot 1270 away from the cavity opening 1110.

[0111] As an example, the second locking part 1230 and the top wall 1135 of the groove can be spaced apart. The second locking part 1230 can be connected to the side wall 1137 of the groove. The second locking part 1230 can be located between the bottom of the top wall 1135 of the groove and the bottom of the slide bar 133, and is spaced apart from the bottom wall 1133 of the groove and the slide bar 133, respectively. The first transverse support arm 1510 can pass through the second locking part 1230 and the top wall 1135 of the groove. The edge side of the second locking part 1230 facing the receiving cavity 111 is approximately arc-shaped, and the inner wall of the second raceway groove 1145 is also approximately arc-shaped. The cross-section of the inner wall of the second raceway groove 1145 and the cross-section of the edge side of the second locking part 1230 can be greater than 1 / 2 circle, so that the second locking groove 1270 can lock the second rolling element 1610.

[0112] Understandably, the second slot 1270 also extends along the length of the slide 1130.

[0113] It should be noted that the installation method of the second rolling element 1610 can refer to the installation method of the first rolling element 1590 in the above embodiment, and will not be repeated here.

[0114] In some embodiments, the bottom and / or top of the slide bar 133 may be recessed with a third raceway groove 1310, and the rolling element 159 may roll in contact with the inner wall of the third raceway groove 1310. In this way, the third raceway groove 1310 can provide a more accurate raceway for the rolling element 159, and the inner wall of the third raceway groove 1310 can restrict the position of the rolling element 159, which helps the rolling element 159 roll more stably and helps the drawer 130 move more stably.

[0115] As an example, the bottom of the slider 133 may be recessed with a third raceway groove 1310, and the top of the first rolling member 1590, which is engaged in the first slot 1250, may protrude out of the first slot 1250 and roll in contact with the inner wall of the third raceway groove 1310.

[0116] As another example, the top of the slider 133 may be recessed with a third raceway groove 1310, and the bottom of the second rolling element 1610, which is engaged in the second slot 1270, may protrude out of the second slot 1270 and roll in contact with the inner wall of the third raceway groove 1310.

[0117] In some embodiments, one end of the third raceway groove 1310 in the direction from the cavity opening 1110 into the receiving cavity 111 can be flared out. The slide bar 133 can be inserted into the slide bar 133 from one end of the flared out, and the flared out can guide the rolling element 159 into the third raceway groove 1310, which helps to make it easier to install the drawer 130.

[0118] As an example, the bottom of the slide bar 133 may be recessed with a third raceway groove 1310. The third raceway groove 1310 can penetrate the slide bar 133 along its length. The end of the third raceway groove 1310 from the cavity opening 1110 toward the receiving cavity 111 is flared. The end of the slide bar 133 with the flared end can be inserted into the slide groove 1130 from the receiving cavity 111 toward the cavity opening 1110. The flared end can guide the first rolling element 1590 into the third raceway groove 1310.

[0119] As another example, the top of the slide bar 133 may be recessed with a third raceway groove 1310. The third raceway groove 1310 can penetrate the slide bar 133 along its length. The third raceway groove 1310 is flared at one end from the cavity opening 1110 toward the receiving cavity 111. The flared end of the slide bar 133 can be inserted into the slide groove 1130 from the receiving cavity 111 toward the cavity opening 1110. The flared end can guide the second rolling element 1610 into the third raceway groove 1310.

[0120] In some embodiments, drawer 130 may have a closed position (e.g., Figure 1 (as shown) and opening position (as shown) Figure 2 As shown, drawer 130 can move from cavity opening 1110 into receiving cavity 111 to the closed position, at which time drawer 130 can be located in receiving cavity 111.

[0121] The drawer 130 can also move from inside the receiving cavity 111 toward the opening 1110 to the open position. At this time, part of the drawer 130 is outside the receiving cavity 111, and the user can conveniently put items into the drawer 130 or take items out of the drawer 130.

[0122] The slide bar 133 may have a first end 1330 and a second end 1350 opposite each other along the moving direction of the drawer 130, and the slide groove 1130 may have a third end 1139 and a fourth end 1141 opposite each other along the moving direction of the drawer 130.

[0123] When drawer 130 is in the closed position, the first end 1330 is closer to the cavity opening 1110 than the second end 1350, and the third end 1139 is closer to the cavity opening 1110 than the fourth end 1141. That is, the first end 1330 and the third end 1139 are located close to the cavity opening 1110, while the second end 1350 and the fourth end 1141 are located inside the receiving cavity 111, away from the cavity opening 1110. The first limiting baffle 1153 is closer to the cavity opening 1110 than the second limiting baffle 1155.

[0124] When drawer 130 is in the closed position, the first end 1330 can be located within the third end 1139, and the second end 1350 can be located within the fourth end 1141. The support assembly 150 is located within the slide groove 1130 and can be located in the middle of the slide bar 133 between the first end 1330 and the second end 1350, and in the middle of the slide groove 1130 between the third end 1139 and the fourth end 1141. Thus, the support assembly 150 can support drawer 130 in the middle of the slide bar 133 and the slide groove 1130, which helps to prevent drawer 130 from tipping over or tilting. At this time, the limiting bracket 151 abuts against the second limiting wall 1155, so that the second limiting wall 1155 can restrict the limiting bracket 151 from moving into the receiving cavity 111 (i.e., from the cavity opening 1110 into the receiving cavity 111) until it disengages from the slide rail 113.

[0125] When drawer 130 is in the open position, the first end 1330 can be located outside the slide rail 1130 and outside the receiving cavity 111, and the second end 1350 can be located inside the third end 1139. The support assembly 150 can be located inside the slide rail 1130 and between the second end 1350 of the slide bar 133 and the third end 1139 of the slide rail 1130. Thus, the support assembly 150 can move with the drawer 130 to adjust the support position, which helps to better support the drawer 130 and improve the situation of the drawer 130 tipping over or tilting. At this time, the limiting bracket 151 abuts against the first limiting baffle 1153, so that the first limiting baffle 1153 can prevent the limiting bracket 151 from disengaging from one end of the cavity opening 1110 from the slide rail 113.

[0126] It should be noted that the travel distance of the support component 150 can be less than that of the drawer 130. For example, the travel distance of the support component 150 is approximately half that of the drawer 130.

[0127] Please see Figures 5 to 7 In some embodiments, the inner wall of the slide groove 1130 may be provided with a first limiting block 1290, the first limiting block 1290 being located at the third end 1139, and the slide bar 133 having a second limiting block 1390 protruding from the side opposite to the drawer body 131, the second limiting block 1390 being located at the second end 1350.

[0128] As an example, the groove sidewall 1137 of the slide 1130 may be provided with a first limiting block 1290. The side of the slide bar 133 facing the groove sidewall 1137 may be provided with a second limiting block 1390.

[0129] The first limiting block 1290 can be located in the movement path of the second limiting block 1390.

[0130] The second limiting block 1390 includes a limiting ramp 1391 and a guiding ramp 1393.

[0131] The limiting inclined surface 1391 can be located between the guide inclined surface 1393 and the first end 1330. The distance between the limiting inclined surface 1391 and the side gradually increases along the direction from the first end 1330 to the second end 1350. The limiting inclined surface 1391 is used to block the first limiting block 1290 when the drawer 130 is in the open position, thereby preventing the drawer 130 from easily disengaging from the slide rail 1130.

[0132] The distance between the guide ramp 1393 and the side gradually decreases from the first end 1330 to the second end 1350. The guide ramp 1393 is used to guide the second end 1350 of the slide bar 133 into the third end 1139 of the slide groove 1130. When the drawer 130 needs to be installed in the cabinet 110, the second end 1350 of the slide bar 133 can be aligned with the port of the third end 1139 of the slide groove 1130 and inserted into the slide groove 1130. At this time, the guide ramp 1393 can slide to contact the first limit block 1290 to guide the second end 1350 of the slide bar 133 into the third end 1139 of the slide groove 1130. When the guide ramp 1393 and the first limit block 1290 slide to contact each other, it can also provide the user with tactile feedback of the slide bar 133 and the slide groove 1130, which makes it easier for the user to judge that the slide bar 133 has been accurately inserted into the slide groove 1130, thus improving the user experience.

[0133] The angle between the limiting inclined surface 1391 and the side surface is greater than the angle between the guiding inclined surface 1393 and the side surface, which helps the limiting inclined surface 1391 to have a larger slope to abut against the first limiting block 1290 for limiting, while the guiding inclined surface 1393 has a smaller slope, which helps to guide the second end 1350 of the slide bar 133 into the third end 1139 of the slide groove 1130 with less effort.

[0134] Please see Figure 3 , Figure 6 and Figure 8 In some embodiments, the rolling element 159 may also be a roller (e.g., ... Figure 8 As shown, the roller can have a stable rolling trajectory, thus eliminating the need to recess raceways on the inner walls of the slide bar 133 and the slide rail 1130, reducing the manufacturing difficulty of the slide bar 133 and the slide rail 113.

[0135] The outer wall of the drawer 130 body may be provided with a first limiting part 1311 (e.g. Figure 6 As shown, the first limiting part 1311 is used to abut against the slide rail 113 to limit the movement of the drawer 130 in the distribution direction of the two slide bars 133. In this way, the first limiting part 1311 and the roller can not only reduce the manufacturing difficulty of the slide bars 133 and the slide rail 113, but also help to prevent the drawer 130 from wobbling left and right.

[0136] As an example, the outer wall of drawer 130 is provided with two opposing first limiting parts 1311, each of which can be used to abut against a slide rail 113, thereby preventing drawer 130 from wobbling left and right.

[0137] The first limiting part 1311 can be a strip-shaped structure and can extend along the moving direction of the drawer 130. In this way, as the drawer 130 moves, a portion of the first limiting part 1311 can always abut against the slide rail 113.

[0138] In some embodiments, a second limiting part may be provided on the slide rail 113. The second limiting part is used to abut against the outer wall of the drawer 130 body to limit the movement of the drawer 130 in the distribution direction of the two slide bars 133. The second limiting part can also reduce the manufacturing difficulty of the slide bars 133 and the slide rail 113, and prevent the drawer 130 from wobbling left and right (i.e. wobbling in the horizontal X direction).

[0139] The number, specific structure, and beneficial effects of the second limiting part can all refer to the first limiting part 1311 in the above embodiment. The only difference is that the second limiting part protrudes on the slide rail 113, while the first limiting part 1311 protrudes on the outer wall of the drawer 130 body.

[0140] In the storage device 100 provided in this application embodiment, a slide rail 113 is provided on the inner wall of the receiving cavity 111 of the housing 110. The slide rail 113 has a slide groove 1130, and a slide strip 133 is provided on the outer wall of the drawer body 131. The rolling element 159 rolls in contact with the inner wall of the slide groove 1130 and the slide strip 133, thereby avoiding contact friction between the slide strip 133 and the slide groove 1130, which helps the drawer 130 move more smoothly. Furthermore, by setting the support component 150 to move with the drawer 130, the support position of the support component 150 between the slide strip 133 and the slide groove 1130 is adjusted to better support the drawer 130, which helps the drawer 130 move more stably. Furthermore, by configuring the retaining bracket 151 to be snapped onto the slide rail 113 from the side facing or away from the receiving cavity 111, the retaining bracket 151 can only be installed and removed from the side of the slide rail 113. When the drawer 130 is pulled out from the receiving cavity 111, the situation where the retaining bracket 151 disengages from the slide rail 113 can be reduced, which helps the support assembly 150 to support the drawer 130 more stably.
