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, refrigerators are increasingly demanding higher and higher standards from users regarding their storage functions.
[0003] Currently, the drawers and cabinets inside refrigerators are usually connected by separate metal slide rails to ensure smooth drawer movement. However, the manufacturing cost of separate metal slide rails is relatively high, making it difficult to meet user needs. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a storage device that can reduce the manufacturing cost of the storage device while ensuring the smoothness and stability of drawer movement.
[0005] According to a first aspect of the present invention, a storage device includes a box, a drawer, and a support assembly. The box includes a box body and slide rails. The box body has a receiving cavity with an open opening. The inner wall of the receiving cavity has two opposing slide rails. The slide rails have a communicating sliding groove and a limiting groove. The end of the limiting groove near the opening has a first baffle. The drawer includes a drawer body and slide bars. The outer wall of the drawer body has two opposing slide bars. Each slide bar is slidably connected to a slide rail via at least one support assembly. The strip is at least partially inserted into the slide groove and is movable along the length of the slide groove; the support assembly includes a limiting frame and a rolling element, the limiting frame is partially movably disposed between the slide strip and the inner wall of the slide groove and partially movably disposed within the limiting groove; the rolling element is rotatably connected to the portion of the limiting frame located between the slide strip and the inner wall of the slide groove, and can roll in contact with the inner wall of the slide groove and the slide strip, configured to roll as the drawer moves, and drive the limiting frame to move along the direction of the drawer's movement; the first baffle is used to limit the travel of the limiting frame towards the cavity opening.
[0006] The storage device according to the embodiments of this utility model has at least the following beneficial effects: By providing a slide rail with a groove on the inner wall of the receiving cavity of the cabinet, and providing a slide bar on the outer wall of the drawer body, the rolling element rolls in contact with the inner wall of the groove and the slide bar, thereby avoiding contact friction between the slide bar and the groove, which helps the drawer move more smoothly. Furthermore, by setting the support component to move with the drawer, the support position of the support component between the slide bar and the groove is adjusted to better support the drawer, which helps the drawer move more stably. In addition, by providing a limiting groove that communicates with the groove, and providing a first baffle at the end of the limiting groove near the cavity opening, the first baffle can limit the travel of the limiting frame towards the cavity opening, thereby restricting the support component on the slide rail, which helps prevent the limiting frame and the rolling element from detaching from the groove opening. The rolling element can support the drawer more stably, further ensuring the stability of the drawer's movement. Compared to the method of setting separate metal slide rails between the drawer and the box in related technologies, the storage device provided in this application only requires a movable support component between the drawer and the box to ensure the smoothness and stability of the drawer movement, and the manufacturing cost is lower.

[0035] 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.
[0036] The storage device 100 includes a housing 110, a drawer 130, and a support assembly 150.
[0037] The cabinet 110 may have one or more storage compartments, and each storage compartment may have at least one drawer 130.
[0038] 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.
[0039] 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).
[0040] 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.
[0041] The inner wall of the accommodating cavity 111 is provided with two opposing slide rails 113, each slide rail 113 is provided with a slide groove 1130 and a limiting groove 1150, and the slide groove 1130 and the limiting groove 1150 are connected to each other.
[0042] 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.
[0043] The limiting groove 1150 is provided with a first baffle 1151 at one end near the cavity opening 1110. The first baffle 1151 can be the inner wall of the limiting groove 1150 at one end near the cavity opening 1110.
[0044] Drawer 130 includes drawer body 131 and slide rail 133. Two opposing slide rails 133 are provided on the outer wall of drawer body 131. Each slide rail 133 is slidably connected to a slide rail 113 by at least one support component 150, thereby avoiding direct contact and friction between the slide rail 133 and the inner wall of the slide rail 1130.
[0045] As an example, the accommodating cavity 111 is provided with a slide rail 113 on each of its two inner side walls, and the drawer body 131 is provided with a slide bar 133 on each of its two outer side walls.
[0046] As another example, the inner bottom wall of the accommodating cavity 111 is provided with two opposing slide rails 113, and the bottom wall of the drawer body 131 is provided with two bent slide bars 133, for example, the slide bars 133 are roughly L-shaped.
[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] The slide bar 133 is at least partially inserted into 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 relative to the box 110 in the slide groove 1130, making it easy to open or close the drawer 130.
[0049] Specifically, the support assembly 150 includes a limiting frame 151 and a rolling element 159. The limiting frame 151 is partially movably disposed between the inner wall of the slide bar 133 and the slide groove 1130, and partially movably disposed within the limiting groove 1150. The rolling element 159 is rotatably connected to the portion of the limiting frame 151 located between the inner wall of the slide bar 133 and the slide groove 1130. The rolling element 159 can roll in contact with the inner wall of the slide groove 1130 and the slide bar 133. The rolling element 159 is configured to roll as the drawer 130 moves, thereby driving the limiting frame 151 to move in the direction of the drawer 130's movement. In this way, the rolling element 159 can roll in contact with the inner wall of the slide bar 133 and the slide groove 1130, which helps to prevent the slide bar 133 from colliding with the slide groove 1130. The contact friction between the inner walls of the groove 1130 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 support component 150 between the slide bar 133 and the slide groove 1130 to better support the drawer 130 and help the drawer 130 move more stably. Compared with the method of setting a separate metal slide rail 113 between the drawer 130 and the box 110 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] When the rolling element 159 drives the limit frame 151 to move, the limit frame 151 can move within the slide groove 1130 and the limit groove 1150.
[0051] The first baffle 1151 is used to limit the travel of the limit bracket 151 toward the cavity opening 1110, thereby restricting the support assembly 150 on the slide rail 113. This helps to prevent the limit bracket 151 and the rolling element 159 from disengaging from one end of the cavity opening 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.
[0052] As an example, when the drawer 130 needs to be cleaned, it can be moved from the receiving cavity 111 towards the opening 1110 to disengage it from the housing 110. At this time, the first baffle 1151 can use the blocking limit bracket 151 to restrict the support component 150 onto the slide rail 113, preventing the limit bracket 151 from disengaging from the slide rail 113 along with the drawer 130, thus 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, simply insert the sliding strips 133 on both sides of the drawer 130 into the slide grooves 1130. This convenient installation ensures smooth movement of the drawer 130.
[0053] In some embodiments, the continuous extension length of the groove 1130 and the continuous extension length of the slide bar 133 are both 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 1133 and the side wall 1137 of the 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.
[0054] 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.
[0055] 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.
[0056] The limiting groove 1150 can be located on the side of the slide groove 1130 opposite to the receiving cavity 111.
[0057] 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.
[0058] 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.
[0059] Please see Figures 2 to 4 In some embodiments, the rolling element 159 is mounted on the limit frame 151 in a manner that allows it to rotate relative to the limit frame 151 but not to move horizontally or vertically (i.e., in the vertical direction Y) relative to the limit frame 151. This prevents the rolling element 159 from detaching from the limit frame 151 and helps the limit frame 151 and drawer 130 move more stably.
[0060] As an example, the limiting frame 151 may have a first connecting shaft and a second connecting shaft that are spaced apart from each other. The first connecting shaft and the second connecting shaft are spaced apart from each other and coaxially arranged in the horizontal direction X. The rolling element 159 may be a ball bearing. The rolling element 159 may have a first connecting hole and a second connecting hole. The first connecting hole and the second connecting hole may be distributed on opposite sides of the rolling element 159 in the horizontal direction X and coaxially arranged. The first connecting shaft may be inserted into the first connecting hole, and the second connecting shaft may be inserted into the second connecting hole. The rolling element 159 can only rotate around the axis of the first connecting shaft and the second connecting shaft.
[0061] As another example, the rolling element 159 may be a roller that is rotatably connected to the limit frame 151.
[0062] In some embodiments, the limiting frame 151 may be provided with a limiting through hole 1510, and the rolling element 159 may be a ball, which is spherically shaped.
[0063] The wall of the limiting through hole 1510 can be spherical. The diameter of the top opening and the bottom opening of the limiting through hole 1510 can be smaller than the diameter of the ball. The ball is rotatably locked in the limiting through hole 1510. Thus, the top opening of the limiting through hole 1510 can restrict the rolling element 159 from disengaging from the top of the limiting through hole 1510, while the bottom opening of the limiting through hole 1510 can restrict the rolling element 159 from disengaging from the bottom of the limiting through hole 1510. In this way, the rolling element 159 can be rotatably locked in the limiting through hole 1510.
[0064] It should be noted that the limiting bracket 151 can be made of plastic material. The top and bottom openings of the limiting through hole 1510 can undergo plastic deformation. The rolling element 159 can be pressed into the limiting through hole 1510 through the top or bottom opening of the limiting through hole 1510, thereby rotatably connecting the rolling element 159 to the limiting through hole 1510.
[0065] The top and bottom of the ball protrude outside the limiting through hole 1510 so as to roll into contact with the inner wall of the slide bar 133 and the groove 1130.
[0066] In some embodiments, the chute 1130 may include a groove opening 1131, a groove top wall 1133, a groove bottom wall 1135, and a groove side wall 1137.
[0067] The sidewall 1137 of the groove can be arranged opposite to the groove opening 1131 at intervals.
[0068] As an example, the slot sidewall 1137 and the slot opening 1131 can be distributed along the horizontal direction X, and the drawer body 131 and the slot sidewall 1137 can be located on opposite sides of the slot opening 1131 along the horizontal direction X.
[0069] The top wall 1133 and the bottom wall 1135 of the tank extend from the top and bottom of the opening 1131 to the side wall 1137 of the tank, respectively.
[0070] As an example, the top wall 1133 and the bottom wall 1135 of the tank can be spaced apart from each other in the vertical direction Y, and the top wall 1133 can be located above the bottom wall 1135.
[0071] The slot 1131 can be formed as an installation port for the limit frame 151 to be installed in the slide groove 1130 and the limit groove 1150, so that the limit frame 151 can be installed from the accommodating cavity 111 through the slot 1131 into the slide groove 1130 and the limit groove 1150, which helps to reduce the installation difficulty of the limit frame 151.
[0072] The slide bar 133 can be inserted into the slide groove 1130 at least partially through the groove opening 1131. There can be gaps between the top wall 1133, the bottom wall 1135, and the side wall 1137 of the groove and the slide bar 133, and the limiting frame 151 can be partially located in the gap.
[0073] As an example, when installing the limit bracket 151 and the drawer 130, the limit bracket 151 can be inserted from the slot 1131 into the slide groove 1130 and the limit groove 1150, and the slide bar 133 on the drawer 130 can be inserted from the end of the slide groove 1130 near the cavity 1110 into the slide groove 1130.
[0074] It should be noted that the rolling element 159 can be snapped onto the limit frame 151 to be installed synchronously with the limit frame 151, or the limit frame 151 can be installed first, and then the rolling element 159 can be installed on the limit frame 151, and then the slide bar 133 on the drawer 130 can be inserted into the slide groove 1130 from the end of the slide groove 1130 near the cavity opening 1110.
[0075] In some embodiments, the slide rail 113 may also be provided with a connecting groove 1170, which may be located between the slide groove 1130 and the limiting groove 1150. The connecting groove 1170 may connect the slide groove 1130 and the limiting groove 1150, thereby providing the limiting frame 151 with an opening through which the slide groove 1130 is inserted into the limiting groove 1150. The limiting frame 151 may be sequentially inserted from the opening 1131 into the slide groove 1130, the connecting groove 1170 and the limiting groove 1150, and the limiting frame 151 may move simultaneously within the slide groove 1130, the connecting groove 1170 and the limiting groove 1150.
[0076] As an example, the slide 1130, the connecting groove 1170, and the limiting groove 1150 can all extend in the same direction along the moving direction of the drawer 130.
[0077] The vertical height of the connecting groove 1170 can be less than the vertical height of the sliding groove 1130, and the vertical height of the connecting groove 1170 can be less than the vertical height of the limiting groove 1150.
[0078] As an example, the connecting groove 1170 may include a first inner top wall and a first inner bottom wall that are vertically spaced apart, with the first inner top wall located above the first inner bottom wall. The limiting groove 1150 may include a second inner top wall and a second inner bottom wall that are vertically spaced apart, with the second inner top wall located above the second inner bottom wall. A first baffle 1151 may be connected between the second inner top wall and the second inner bottom wall. The vertical height of the first inner bottom wall relative to the bottom of the slide rail 113 may be higher than the vertical height of the groove bottom wall 1135 relative to the bottom of the slide rail 113, and the vertical height of the first inner bottom wall relative to the bottom of the slide rail 113 may be higher than the vertical height of the second inner bottom wall relative to the bottom of the slide rail 113; and / or, the height of the first inner top wall relative to the bottom of the slide rail 113 may be lower than the vertical height of the groove top wall 1133 relative to the bottom of the slide rail 113, and the vertical height of the first inner top wall relative to the bottom of the slide rail 113 may be lower than the vertical height of the second inner top wall relative to the bottom of the slide rail 113.
[0079] The limiting bracket 151 may include a rolling connecting part 1550 and a stop part 1570. The rolling connecting part 1550 is movably disposed between the inner wall of the slide bar 133 and the slide groove 1130. The rolling element 159 is rotatably connected to the rolling connecting part 1550. The rolling element 159 is configured to roll as the drawer 130 moves and drive the rolling connecting part 1550 to move in the slide groove 1130 along the moving direction of the drawer 130. When the rolling connecting part 1550 moves, it can drive the stop part 1570 to move synchronously in the connecting groove 1170 and the limiting groove 1150.
[0080] Specifically, the stop part 1570 can extend from the rolling connection part 1550 and pass through the connecting groove 1170 and the limiting groove 1150. The first baffle 1151 can be used to limit the travel of the stop part 1570 from the receiving cavity 111 to the cavity opening 1110. Thus, the first baffle 1151 can limit the travel of the limiting frame 151 by limiting the travel of the stop part 1570.
[0081] In some embodiments, the rolling connection 1550 and the stop 1570 can be integrally formed, which helps to reduce the number of parts and reduce assembly difficulty.
[0082] In some embodiments, a stepped surface 1190 facing the limiting groove 1150 may be formed at the junction of the limiting groove 1150 and the connecting groove 1170.
[0083] As an example, the step surface 1190 may be connected to the first inner top wall and extend upward to the second inner top wall.
[0084] As another example, the stepped surface 1190 may be connected to the first inner bottom wall and extend downward to the second inner bottom wall.
[0085] The limiting bracket 151 may also include a snap fastener 1530, which may be vertically protruding from the end of the stop portion 1570 away from the rolling connection portion 1550. The snap fastener 1530 may be used to abut against the step surface 1190, thereby limiting the movement of the limiting bracket 151 in the horizontal direction X. This helps to prevent the limiting bracket 151 from moving in the horizontal direction X to contact the slide bar 133, which would cause the drawer 130 to move too slowly.
[0086] As an example, when drawer 130 moves normally, the inverted latch 1530 and the stepped surface 1190 can be spaced apart to avoid the sliding friction between the inverted latch 1530 and the stepped surface 1190 affecting the smoothness of the movement of the limit frame 151 and drawer 130. This also provides a moving part for the limit frame 151 along the horizontal direction X, helping to prevent the limit frame 151 from jamming. When drawer 130 wobbles on the left and right sides along the direction of movement, for example, when the drawer 130 contains many objects causing uneven weight distribution, the left and right sides of drawer 130 are prone to wobbling, and the limit frame 151 is also prone to lateral movement on the left and right sides along the direction of movement of drawer 130. In this case, the stepped surface 1190 can abut against the inverted latch 1530 to limit the movement of the limit frame 151 along the horizontal direction X to the contact slide bar 133.
[0087] In some embodiments, the buckle 1530 may have a first guide slope 1531 formed on the side opposite to the rolling connection portion 1550. The first guide slope 1531 may be inclined relative to the horizontal plane. The first guide slope 1531 may be used to guide the buckle 1530 through the slide groove 1130 and through the connecting groove 1170, thereby facilitating the insertion of the stop portion 1570 through the connecting groove 1170 into the limiting groove 1150.
[0088] As an example, the first guide ramp 1531 may extend obliquely upward from the end of the buckle 1530 away from the rolling connection portion 1550 and toward one side of the rolling connection portion 1550. When the stop portion 1570 passes through the connecting groove 1170, the first guide ramp 1531 may slide into contact with the first inner top wall to guide the buckle 1530 into the limiting groove 1150.
[0089] As another example, the first guide ramp 1531 may extend obliquely downward from the end of the buckle 1530 away from the rolling connection portion 1550 and toward one side of the rolling connection portion 1550. When the stop portion 1570 passes through the connecting groove 1170, the first guide ramp 1531 may slide into contact with the first inner bottom wall to guide the buckle 1530 into the limiting groove 1150.
[0090] In some embodiments, the stop portion 1570 may include two transverse support rods 1571. Both transverse support rods 1571 can extend laterally from the rolling connection portion 1550 to pass through the connecting groove 1170 and the limiting groove 1150. The two transverse support rods 1571 can be distributed vertically at intervals. The end of each transverse support rod 1571 away from the rolling connection portion 1550 can be provided with a buckle 1530, so that the two buckles 1530 can simultaneously abut against the step surface 1190, which helps to make the movement of the limiting frame 151 more stable and reduces the situation where the limiting frame 151 tilts due to the abutment of a single buckle 1530 against the step surface 1190.
[0091] As an example, the two horizontal support rods 1571 are defined as the first support rod and the second support rod, respectively. There are two inverted buckles 1530, named the first inverted buckle 1530 and the second inverted buckle 1530, respectively. There can also be two stepped surfaces 1190, named the first stepped surface 1190 and the second stepped surface 1190, respectively.
[0092] The first support rod can be spaced above the second support rod. A first buckle 1530 can be connected to the end of the first support rod away from the rolling connection 1550 and protrude upwards. A first stepped surface 1190 can be connected to the first inner top wall and extend upwards to the second inner top wall, and the first stepped surface 1190 can abut against the first buckle 1530. A second buckle 1530 can be connected to the end of the second support rod away from the rolling connection 1550 and protrude downwards. A second stepped surface 1190 can be connected to the first inner bottom wall and extend downwards to the second inner bottom wall, and the second stepped surface 1190 can abut against the second buckle 1530. The first and second buckles 1530 can be symmetrically distributed, and both can be provided with a first guide slope 1531.
[0093] In some embodiments, the rolling connection 1550 may include a first lateral support arm 1551, a second lateral support arm 1553, and a vertical support arm 1555 connected to each other.
[0094] The vertical support arm 1555 can be located between the side wall 1137 of the groove and the slide bar 133.
[0095] As an example, the vertical support arm 1555 can be spaced apart from the groove sidewall 1137 and from the slide bar 133 to reduce contact friction. The vertical support arm 1555 can be plate-shaped and can be parallel to or inclined relative to the vertical plane.
[0096] The first horizontal support arm 1551 can extend laterally from the bottom end of the vertical support arm 1555 and pass through the bottom of the slide bar 133 and the bottom wall 1135 of the groove. The second horizontal support arm 1553 can extend laterally from the top end of the vertical support arm 1555 and pass through the top of the slide bar 133 and the top wall 1133 of the groove.
[0097] As an example, the first transverse support arm 1551 can be spaced apart from the bottom wall 1135 of the groove and from the bottom of the slide bar 133 to reduce contact friction. The second transverse support arm 1553 can be spaced apart from the top wall 1133 of the groove and from the top of the slide bar 133 to reduce contact friction. Both the first transverse support arm 1551 and the second transverse support arm 1553 can be plate-shaped structures. Both the first transverse support arm 1551 and the second transverse support arm 1553 can be parallel to the horizontal plane or inclined relative to the horizontal plane. The first transverse support arm 1551, the vertical support arm 1555, and the second transverse support arm 1553 can be connected sequentially to form a receiving groove, and the slide bar 133 can be at least partially inserted into the receiving groove.
[0098] The stop part 1570 can be connected to the side of the vertical support arm 1555 facing the groove sidewall 1137.
[0099] As an example, the connecting groove 1170 may extend through the groove sidewall 1137 to connect the slide groove 1130 and the limiting groove 1150.
[0100] Both the first horizontal support arm 1551 and the second horizontal support arm 1553 can be connected to rotatable rollers 159. The top and bottom of the rollers 159 connected to the first horizontal support arm 1551 can roll to contact the bottom of the slide bar 133 and the bottom wall 1135 of the groove, respectively. The top and bottom of the rollers 159 connected to the second horizontal support arm 1553 can roll to contact the top wall 1133 of the groove and the top of the slide bar 133, respectively. Thus, the bottom and top of the slide bar 133 are supported by ball bearings, which helps the drawer 130 move more smoothly.
[0101] In some embodiments, the rolling element 159 may include a first rolling element 1590, the limiting through hole 1510 may include a first limiting through hole 1511, the first limiting through hole 1511 may be provided on the first transverse support arm 1551, and the first rolling element 1590 is rotatably connected to the first limiting through hole 1511.
[0102] In some embodiments, there may be multiple first rolling elements 1590 and multiple first limiting through holes 1511. Multiple first limiting through holes 1511 may be distributed sequentially and spaced along the length of the slide groove 1130 on the first transverse support arm 1551. Each first rolling element 1590 is rotatably connected to a limiting through hole 1510. The top of each first rolling element 1590 can rollably contact the bottom of the slide bar 133, and the bottom of each first rolling element 1590 can rollably contact the bottom wall 1135 of the groove. Thus, multiple first rolling elements 1590 can more stably support the drawer 130, reduce the chance of the drawer 130 tipping over, and help the drawer 130 move more smoothly.
[0103] The multiple first rolling elements 1590 can refer to two first rolling elements 1590, three first rolling elements 1590, four first rolling elements 1590, five first rolling elements 1590, or other numbers of first rolling elements 1590.
[0104] In some embodiments, the rolling element 159 may include a second rolling element 1610, the limiting through hole 1510 may include a second limiting through hole 1513, the second limiting through hole 1513 may be provided on the second transverse support arm 1553, and the second rolling element 1610 is rotatably connected to the second limiting through hole 1513.
[0105] In some embodiments, there may be multiple second rolling elements 1610 and multiple second limiting through holes 1513. Multiple second limiting through holes 1513 may be distributed sequentially and spaced along the length of the slide groove 1130 on the second transverse support arm 1553. Each second rolling element 1610 is rotatably connected to a limiting through hole 1510. The top of each second rolling element 1610 can rollably contact the top wall 1133 of the groove, and the bottom of each second rolling element 1610 can rollably contact the top of the slide groove 1130. Thus, multiple second rolling elements 1610 can more stably support the drawer 130, reduce the chance of the drawer 130 tipping over, and help the drawer 130 move more smoothly.
[0106] The plurality of second scroll members 1610 may refer to two second scroll members 1610, three second scroll members 1610, four second scroll members 1610, five second scroll members 1610, or other numbers of second scroll members 1610.
[0107] Please see Figure 1 , Figure 5 and Figure 6 In some embodiments, the end of the vertical support arm 1555 facing away from the cavity opening 1110 may be recessed with a relief groove 1557 (e.g., Figure 5As shown, a limiting block 1390 may protrude from one end of the slide bar 133 in the direction from the cavity opening 1110 into the accommodating cavity 111.
[0108] When the drawer 130 moves from the receiving cavity 111 toward the cavity opening 1110, the clearance groove 1557 is used to allow the limiting block 1390 to enter. In this way, the clearance groove 1557 can provide space for the limiting block 1390 to move, which helps to increase the travel of the drawer 130.
[0109] The groove wall of the clearance groove 1557 facing the cavity opening 1110 is used to block the limiting block 1390, which helps to restrict the drawer 130 within the receiving cavity 111 and prevent the drawer 130 from easily leaving the receiving cavity 111.
[0110] As an example, the end of the clearance groove 1557 facing away from the cavity opening 1110 may have an open opening, and the end facing the cavity opening 1110 may have a limiting wall 1559 (the limiting wall 1559 is the groove wall of the clearance groove 1557 facing the cavity opening 1110). The opening and the limiting wall 1559 may be spaced apart and opposite to each other. When the drawer 130 moves toward the cavity opening 1110, the limiting block 1390 may enter the clearance groove 1557 through the opening, and the limiting wall 1559 may block the limiting block 1390 to prevent the slide bar 133 from disengaging from the slide groove 1130, thereby confining the drawer 130 within the receiving cavity 111.
[0111] In some embodiments, the top and / or bottom of the slide bar 133 may be recessed with a first raceway groove 1310. The first raceway groove 1310 may extend along the length direction of the slide groove 1130. The rolling element 159 may roll in contact with the inner wall of the first raceway groove 1310. In this way, the first raceway groove 1310 can provide a more accurate raceway for the rolling element 159. The inner wall of the first 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.
[0112] As an example, the bottom of the slider 133 may be recessed with a first raceway groove 1310, and the first rolling element 1590 may roll between the inner wall of the first raceway groove 1310 and the bottom wall 1135 of the groove.
[0113] As another example, the top of the slider 133 may be recessed with a first raceway groove 1310, and the second rolling element 1610 may roll between the inner wall of the first raceway groove 1310 and the top wall 1133 of the groove.
[0114] As another example, the bottom of the slide bar 133 may be recessed with a first raceway groove 1310, and the top of the slide bar 133 may also be recessed with a first raceway groove 1310. Then the first rolling element 1590 can roll between the first raceway groove 1310 at the bottom of the slide bar 133 and the bottom wall 1135 of the groove, and the second rolling element 1610 can roll between the first raceway groove 1310 at the top of the slide bar 133 and the top wall 1133 of the groove.
[0115] The first raceway groove 1310 can be configured in various shapes.
[0116] As an example, the first raceway groove 1310 can be an arc-shaped groove, that is, the cross-sectional outline of the first raceway groove 1310 is an arc, so that the rolling element 159 can roll on the arc-shaped inner wall of the first raceway groove 1310.
[0117] As another example, the first raceway groove 1310 can be a rectangular groove, which can include a bottom wall 1135 opposite to the groove opening. The rolling element 159 can roll on the bottom wall 1135 of the groove, and the side walls 1137 on both sides of the rectangular groove can limit the rolling element 159.
[0118] It should be noted that the first raceway groove 1310 can also be a groove of other shapes besides arc-shaped grooves and rectangular grooves, which can be set according to requirements.
[0119] In some embodiments, one end of the first 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 first raceway groove 1310, which helps to make it easier to install the drawer 130.
[0120] As an example, the bottom of the slide bar 133 may be recessed with a first raceway groove 1310. The first raceway groove 1310 can penetrate the slide bar 133 along its length. The first 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 first rolling element 1590 into the first raceway groove 1310.
[0121] As another example, the top of the slide bar 133 may be recessed with a first raceway groove 1310. The first raceway groove 1310 can penetrate the slide bar 133 along its length. The first 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 first raceway groove 1310.
[0122] In some embodiments, the top wall 1133 and / or the bottom wall 1135 of the groove may be recessed with a second raceway groove 1143. The second raceway groove 1143 may extend along the length direction of the slide groove 1130. The rolling element 159 may roll in contact with the inner wall of the second raceway groove 1143. In this way, the second raceway groove 1143 can provide a more accurate raceway for the rolling element 159. The inner wall of the second raceway groove 1143 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.
[0123] It should be noted that at least one of the top wall 1133 and the bottom wall 1135 of the slide groove 1130 is provided with a second raceway groove 1143, and at least one of the bottom and top of the slide bar 133 is provided with a first raceway groove 1310. When both the top wall 1133 and the bottom wall 1135 of the slide groove 1130 are provided with second raceway grooves 1143, and both the bottom and top of the slide bar 133 are provided with first raceway grooves 1310, the first rolling element 1590 can roll simultaneously between the bottom wall 1135 of the first raceway groove 1310 and the inner wall of the second raceway groove 1143, and the second rolling element 1610 can also roll simultaneously between the top wall 1133 of the first raceway groove 1310 and the inner wall of the second raceway groove 1143. This helps to further improve the rolling stability of the first rolling element 1590 and the second rolling element 1610, and improves the stability of the drawer 130 movement.
[0124] The second raceway groove 1143 can also have various shape settings, which can be referred to the shape settings of the first raceway groove 1310, and will not be repeated here.
[0125] Please see Figures 1 to 2 In some embodiments, drawer 130 has a closed position (e.g., Figure 1 (as shown) and opening position (as shown) Figure 2 (As shown).
[0126] The drawer 130 can be moved from the opening 1110 into the receiving cavity 111 to the closed position, at which time the drawer 130 can be located in the receiving cavity 111.
[0127] The drawer 130 can also be moved 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.
[0128] The end of the limiting groove 1150 away from the cavity opening 1110 may also be provided with a second baffle 1153. The second baffle 1153 is used to limit the travel of the limiting frame 151 from the cavity opening 1110 toward the receiving cavity 111. This helps to prevent the limiting frame 151 and the rolling element from disengaging from the end of the slide rail 113 away from the cavity opening 1110. The rolling element 159 can support the drawer 130 more stably, further ensuring the stability of the drawer 130's movement.
[0129] The first baffle 1151 and the second baffle 1153 are spaced apart from each other along the length of the limiting groove 1150, and the support assembly 150 can move between the first baffle 1151 and the second baffle 1153.
[0130] Please see Figures 4 to 6 In some embodiments, the slide bar 133 may have a first end 1330 and a second end 1350 opposite to 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 to each other along the moving direction of the drawer 130.
[0131] Please refer to question 1. Figure 4 and Figure 6 When drawer 130 is in the closed position, the first baffle 1151 is closer to the cavity opening 1110 than the second baffle 1153, 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. The first end 1330 is located inside the third end 1139, the second end 1350 is located inside the fourth end 1141, and the support assembly 150 is located inside the slide groove 1130, and is located in the middle of the slide bar 133 between the first end 1330 and the second end 1350, and in the slide groove 1130 at the third end 1110. The support assembly 150 is located in the middle between the third end 39 and the fourth end 1141, and the limiting bracket 151 abuts against the second baffle 1153. In this way, 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. The second baffle 1153 can prevent the limiting bracket 151 from moving from the cavity opening 1110 into the receiving cavity 111, thereby limiting the movement of the limiting bracket 151 and helping to ensure that the support assembly 150 has a more accurate support position to more stably support the drawer 130.
[0132] Please see Figure 2 , Figure 4 and Figure 6When drawer 130 is in the open position, the first end 1330 is located outside the slide rail 1130, the second end 1350 is located inside the third end 1139, the support assembly 150 is located inside the slide rail 1130, and is located between the second end 1350 of the slide bar 133 and the third end 1139 of the slide rail 1130, and the limiting bracket 151 abuts against the first baffle 1151. In this way, 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. In addition, the first baffle 1151 can prevent the limiting bracket 151 from moving from the accommodating cavity 111 towards the cavity opening 1110, thereby limiting the movement stroke of the limiting bracket 151 and helping to ensure that the support assembly 150 has a more accurate support position to more stably support the drawer 130.
[0133] Please see Figure 3 , Figure 5 and Figure 6 In some embodiments, the rolling element 159 can also be a roller, which can have a stable rolling trajectory, thus eliminating the need to recess the raceway on the inner wall of the slide bar 133 and the slide rail 1130, reducing the manufacturing difficulty of the slide bar 133 and the slide rail 113.
[0134] The outer wall of the drawer body 131 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 bar 133 and the slide rail 113, but also help to prevent the drawer 130 from wobbling left and right (i.e. wobbling in the horizontal direction X).
[0135] 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.
[0136] 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.
[0137] 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 body 131 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.
[0138] 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 body 131.
[0139] Please see Figure 4 and Figure 7 In some embodiments, the inner wall of the slide groove 1130 may be provided with an abutment block 1210, the abutment block 1210 is located at the third end 1139, and the slide bar 133 is provided with a limiting block 1390 on the side opposite to the drawer body 131, the limiting block 1390 is located at the second end 1350.
[0140] As an example, the groove sidewall 1137 of the slide 1130 may be provided with an abutment block 1210. The side of the slide bar 133 facing the groove sidewall 1137 may be provided with a limiting block 1390.
[0141] The abutment block 1210 can be located in the movement path of the limit block 1390.
[0142] The limiting block 1390 includes a limiting inclined surface 1391 and a second guiding inclined surface 1393.
[0143] The limiting inclined surface 1391 can be located between the second guide inclined surface 1393 and the first end 1330. The distance between the limiting inclined surface 1391 and the side gradually increases from the first end 1330 to the second end 1350. The limiting inclined surface 1391 is used to abut against the abutment block 1210 when the drawer 130 is in the open position, thereby preventing the drawer 130 from easily disengaging from the slide 1130.
[0144] It should be noted that the end wall of the abutment block 1210 facing away from the cavity opening 1110 and the first baffle wall 1151 (as shown in the figure) Figure 2 (As shown) can be on the same plane. When drawer 130 is in the open position, stop part 1570 can abut against the first stop wall 1151, vertical support arm 1555 can abut against the end wall of abutment block 1210 opposite to cavity opening 1110, and limiting inclined surface 1391 can abut against limiting wall 1559 (as shown) Figure 5 (As shown) it indirectly abuts against the abutment block 1210.
[0145] The distance between the second guide slope 1393 and the side gradually decreases from the first end 1330 to the second end 1350. The second guide slope 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 second guide slope 1393 can slide to contact the abutment block 1210 to guide the second end 1350 of the slide bar 133 into the third end 1139 of the slide groove 1130. When the second guide slope 1393 and the abutment block 1210 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.
[0146] The angle between the limiting inclined surface 1391 and the side surface is greater than the angle between the second guiding inclined surface 1393 and the side surface, which helps the limiting inclined surface 1391 to have a greater slope to abut against the abutment block 1210, while the slope of the second guiding inclined surface 1393 is smaller, 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.
[0147] In the storage device 100 provided in this application embodiment, a slide rail 113 with a slide groove 1130 is provided on the inner wall of the receiving cavity 111 of the box body 110, and a slide bar 133 is provided on the outer wall of the drawer body 131. This allows the rolling element 159 to roll and contact the inner wall of the slide groove 1130 and the slide bar 133, thereby avoiding contact friction between the slide bar 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 bar 133 and the slide groove 1130 is adjusted to better support the drawer 130, which helps the drawer 130 move more stably. Furthermore, by setting a limiting groove 1150 that communicates with the slide rail 1130, and setting a first baffle 1151 at one end of the limiting groove 1150 near the cavity opening 1110, the first baffle 1151 can limit the travel of the limiting frame 151 toward the cavity opening 1110, thereby restricting the support component 150 on the slide rail 113. This helps to prevent the limiting frame 151 and the rolling element 159 from detaching from the cavity opening 1110 and 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. Compared with the method of setting a separate metal slide rail 113 between the drawer 130 and the box 110 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.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
