[0038] Please see Figures 1 to 3 This application provides a storage device 100, which includes a box 110, a drawer 130 and a plurality of rolling elements 150.

[0039] The storage device 100 can refer to a refrigerator, cabinet, or other storage device 100. For ease of description, the following explanation will use a refrigerator as an example of the storage device 100.

[0040] As an example, taking the storage device 100 as a refrigerator, the cabinet 110 may be provided with a refrigeration chamber, a freezing chamber, an ice-making chamber, etc., and the drawer 130 may refer to the drawer 130 located in any of the above-mentioned chambers.

[0041] The box 110 includes a box body and a first sliding member 115. Two opposing first sliding members 115 are provided on the inner wall of the box body. The two first sliding members 115 can be used to support the drawer 130.

[0042] Drawer 130 includes drawer body 131 and second sliding member 133. Two opposing second sliding members 133 are provided on the outer wall of drawer body 131.

[0043] The first slider 115 and the second slider 133 are slidably connected by multiple rolling elements 150, which reduces the direct contact friction between the first slider 115 and the second slider 133, helps to reduce the moving resistance of the drawer 130, and makes the drawer 130 move more smoothly.

[0044] One of the first sliding member 115 and the second sliding member 133 has a groove 1150, and the other has a slide bar 1330. The slide bar 1330 is at least partially inserted into the groove 1150, and the slide bar 1330 can move relative to the groove 1150 along the length of the groove 1150, so that the drawer 130 can move back and forth relative to the cabinet 110, making it easy to open the drawer 130 (e.g., Figure 2 (as shown) and close drawer 130 (as shown) Figure 1 (As shown).

[0045] As an example, the first slider 115 may be formed with a groove 1150, and the second slider 133 may be formed with a slider 1330 or the second slider 133 may be formed as a slider 1330.

[0046] As another example, the first slider 115 is formed with a slide bar 1330 or the first slider 115 is formed as a slide bar 1330, and the second slider 133 is formed with a groove 1150.

[0047] The first sliding member 115 can be installed in various ways on the inner wall of the box body, and the second sliding member 133 can also be installed in various ways on the outer wall of the drawer body 131.

[0048] As an example, a first sliding member 115 is provided on each of the two opposite inner sidewalls of the box body, and a second sliding member 133 is provided on each of the two opposite outer sidewalls of the drawer body 131.

[0049] As another example, the first slider 115 is formed with a groove 1150, and the second slider 133 can be formed with a slide bar 1330. The inner bottom wall of the box body is provided with two opposing first sliders 115, and the bottom wall of the drawer body 131 is provided with two bent second sliders 133, for example, the second sliders 133 are roughly L-shaped.

[0050] For ease of description, the following explanation will be based on the premise that a first sliding member 115 is provided on each of the two opposite inner sidewalls of the box body, and a second sliding member 133 is provided on each of the two opposite outer sidewalls of the drawer body 131.

[0051] At least one of the first sliding member 115 and the second sliding member 133 is provided with an annular groove 1190 and a communication port 170 (e.g., ...). Figure 5 and Figure 8 As shown), the connecting port 170 connects the annular groove 1190 and the sliding groove 1150.

[0052] Each annular groove 1190 is provided with multiple rolling elements 150 that can roll within the annular groove 1190. At least one of the multiple rolling elements 150 can rollably contact the inner wall of the slide bar 1330 and / or the groove 1150 through the connecting port 170. In this way, the slide bar 1330 and the inner wall of the groove 1150 can be rolled together by the rolling elements 150, which helps to reduce sliding friction and makes the drawer 130 move more smoothly and stably. Furthermore, the rolling elements 150 can roll within the annular groove 1190, which helps to ensure the smooth and stable movement of the drawer 130. In addition, compared with the use of metal split slide rails in related technologies, the storage device 100 provided in this application embodiment can directly integrate multiple rolling elements 150 into the annular groove 1190 of the sliding element (i.e., the first sliding element 115 or the second sliding element 133), simplifying the sliding structure between the drawer 130 and the cabinet 110. The storage device 100 has a higher degree of integration and lower manufacturing cost.

[0053] At least one scroll member 150 may refer to one scroll member 150, two scroll members 150, three scroll members 150, four scroll members 150, or any other number of scroll members 150.

[0054] The rolling element 150 can roll in contact with the inner wall of the slide bar 1330 and / or the slide groove 1150 through the connecting port 170. This can mean that the rolling element 150 is flush with the connecting port 170 and can roll in contact with the inner wall of the slide bar 1330 and / or the slide groove 1150; or it can mean that part of the rolling element 150 protrudes into the slide groove 1150 through the connecting port 170 and can roll in contact with the inner wall of the slide bar 1330 and / or the slide groove 1150.

[0055] For ease of understanding, this application embodiment uses the example of a rolling element 150 protruding through the communication port 170 into the slide groove 1150 and rollingly contacting the slide bar 1330 and / or the inner wall of the slide groove 1150 for explanation.

[0056] As an example, the first slider 115 has a groove 1150, and the second slider 133 has a slider 1330. The first slider 115 may have an annular groove 1190 and a connecting port 170. At least one of the plurality of rolling elements 150 installed in the annular groove 1190 partially protrudes from the groove 1150 through the connecting port 170 and rollably contacts the slider 1330.

[0057] As another example, the first slider 115 has a groove 1150, and the second slider 133 has a slider 1330. The second slider 133 may have an annular groove 1190 and a connecting port 170. At least one of the plurality of rolling elements 150 installed in the annular groove 1190 protrudes partially from the groove 1150 through the connecting port 170 to rollably contact the inner wall of the groove 1150.

[0058] As another example, the first slider 115 has a groove 1150, and the second slider 133 has a slider strip 1330. The first slider 115 may have an annular groove 1190 and a connecting opening 170. At least one of the plurality of rolling elements 150 installed in the annular groove 1190 of the first slider 115 partially protrudes from the groove 1150 through the connecting opening 170 to rollably contact the slider strip 1330. The second slider 133 may also have an annular groove 1190 and a connecting opening 170. At least one of the plurality of rolling elements 150 installed in the annular groove 1190 of the second slider 133 partially protrudes from the groove 1150 through the connecting opening 170 to rollably contact the inner wall of the groove 1150.

[0059] It should be noted that the first sliding member 115 may also be formed with a slide bar 1330, and the second sliding member 133 may be a slide groove 1150. The rolling member 150 protruding in the slide groove 1150 can also roll in contact with the inner wall of the slide bar 1330 or the slide groove 1150, which will not be described in detail here.

[0060] In some embodiments, the two opposite inner sidewalls of the box body can be integrally formed with a first sliding member 115, thereby reducing the manufacturing cost of the box body 110, further simplifying the assembly steps of the storage device 100, and contributing to a higher degree of integration of the storage device 100.

[0061] As an example, both the box body and the first sliding member 115 can be made of plastic, so the box body and the first sliding member 115 can be vacuum-formed into a single structure. Understandably, the box body and the first sliding member 115 can also be made of other materials, so the box body and the first sliding member 115 can also be made of other single-piece forming processes.

[0062] In some embodiments, a second sliding member 133 is integrally formed on each of the two opposite outer walls of the drawer body 131, thereby reducing the manufacturing cost of the drawer 130, further simplifying the assembly steps of the storage device 100, and contributing to a higher degree of integration of the storage device 100.

[0063] As an example, the drawer body 131 and the second sliding member 133 can both be made of plastic, so the drawer body 131 and the second sliding member 133 can be vacuum-formed into a one-piece structure. Understandably, the drawer body 131 and the second sliding member 133 can also be made of other materials, so the drawer body 131 and the second sliding member 133 can also be made of other one-piece molding processes.

[0064] Please see Figure 3 , Figure 5 and Figure 6 In some embodiments, the shape of the annular groove 1190 can be configured in various ways.

[0065] As an example, the annular groove 1190 can be annular, elliptical, rounded rectangle, or other annular shapes. Specifically, the annular trajectory of the annular groove 1190 can be annular, elliptical, rounded rectangle, elliptical rectangle, or other annular shapes.

[0066] In some embodiments, the chute 1150 may include a first groove opening 1151, a top wall 1153, a bottom wall 1155, and a side wall 1157.

[0067] The sidewall 1157 of the groove can be arranged opposite to the first groove opening 1151 at intervals.

[0068] As an example, the slot sidewall 1157 and the first slot opening 1151 can be distributed along the horizontal direction X, and the drawer body 131 and the slot sidewall 1157 can be located on opposite sides of the first slot opening 1151 along the horizontal direction X.

[0069] The top wall 1153 can extend from the top of the first groove 1151 to the side wall 1157, and the bottom wall 1155 can extend from the bottom of the first groove 1151 to the side wall 1157.

[0070] As an example, the top wall 1153 and the bottom wall 1155 of the tank can be spaced apart from each other in the vertical direction Z, and the top wall 1153 can be located above the bottom wall 1155.

[0071] The slide bar 1330 can be inserted into the slide groove 1150 at least partially through the first groove 1151. There can be gaps between the top wall 1153, bottom wall 1155, and side wall 1157 of the groove and the slide bar 1330 to reduce sliding friction.

[0072] In some embodiments, the annular groove 1190 may include an outer annular wall 1197 and an inner annular wall 1199 spaced apart. A plurality of rolling elements 150 are sequentially distributed between the outer annular wall 1197 and the inner annular wall 1199 along an annular trajectory. Thus, the outer annular wall 1197 and the inner annular wall 1199 can restrict the position of the rolling elements 150. When the drawer 130 moves, the plurality of rolling elements 150 can roll in an orderly manner within the annular groove 1190, reducing the possibility of the rolling elements 150 getting stuck.

[0073] As an example, multiple rolling elements 150 can rollably contact the outer ring wall 1197 and the inner ring wall 1199. The outer ring wall 1197 and the inner ring wall 1199 can be separately spaced apart, or they can be connected by other structures.

[0074] The connecting port 170 can be provided through the outer ring wall 1197, so that when the multiple rolling elements 150 roll in the annular groove 1190 and pass through the connecting port 170, at least one rolling element 150 can be partially exposed in the slide groove 1150 through the connecting port 170 to roll and contact the slide bar 1330 or the inner wall of the slide groove 1150.

[0075] It should be noted that the plane containing the annular track of the annular groove 1190 can be inclined relative to the horizontal plane or set along a vertical plane, so that the rolling element 150 can roll and contact the top or bottom of the slide bar 1330, or the bottom wall 1155 or top wall 1153 of the groove after being exposed through the connecting port 170 on the outer annular wall 1197. When the annular track of the annular groove 1190 is inclined relative to the horizontal plane, the inclination angle can be set according to actual needs.

[0076] In some embodiments, the annular groove 1190 may further include an annular end wall 1201. The outer annular wall 1197 and the inner annular wall 1199 may be connected to the outer annular side and the inner annular side of the annular end wall 1201, respectively. This allows the outer annular wall 1197 and the inner annular wall 1199 to be connected through the annular end wall 1201, which helps to simplify the structure of the annular groove 1190 and reduce manufacturing difficulty.

[0077] As an example, the annular groove 1190 may also include an annular opening, the annular end wall 1201 and the annular opening may be arranged at intervals relative to each other, the outer annular wall 1197 may extend from the outer annular side of the annular opening to the outer annular side of the annular end wall 1201, and the inner annular wall 1199 may extend from the inner annular side of the annular groove to the inner annular side of the annular end wall 1201.

[0078] Understandably, the orientation of the annular groove opening will differ depending on the arrangement of the plane containing the annular track of the annular groove 1190. For example, when the plane containing the annular track of the annular groove 1190 is inclined relative to the horizontal plane, the annular groove opening can be inclined upwards or downwards; when the plane containing the annular track of the annular groove 1190 is arranged along a vertical plane, the annular groove opening can be directed towards the drawer body 131 in the horizontal direction X or towards the side away from the drawer body 131 in the horizontal direction X.

[0079] Multiple rolling elements 150 can be sequentially distributed along an annular trajectory between the outer annular wall 1197, the inner annular wall 1199, and the annular end wall 1201. Thus, the outer annular wall 1197, the inner annular wall 1199, and the annular end wall 1201 can restrict the position of the rolling elements 150. When the drawer 130 moves, the multiple rolling elements 150 can roll in an orderly manner within the annular groove 1190, reducing the possibility of the rolling elements 150 getting stuck.

[0080] As an example, multiple rolling elements 150 can rollably contact the outer annular wall 1197, the inner annular wall 1199, and the annular end wall 1201.

[0081] The connecting port 170 can penetrate the outer ring wall 1197 and / or the annular end wall 1201, so that when the multiple rolling elements 150 roll through the connecting port 170 in the annular groove 1190, at least one rolling element 150 can roll through the connecting port 170 to contact the inner wall of the slide bar 1330 or the groove 1150.

[0082] As an example, the connecting port 170 can be provided on the annular end wall 1201, and the plane on which the annular trajectory of the annular groove 1190 is located can be set along the horizontal plane. The annular groove opening can be set upward or downward in the vertical direction Z, so that the rolling element 150 can be exposed through the connecting port 170 to rollably contact the top or bottom of the slide bar 1330 or the bottom wall 1155 or the top wall 1153 of the groove, and helps to reduce the space occupied by the annular groove 1190 in the vertical direction Z.

[0083] As another example, the connecting port 170 can be provided through the outer ring wall 1197, then the plane on which the annular track of the annular groove 1190 is located can be set along the vertical plane, and the annular groove opening can face the side of the horizontal direction X, so that the rolling element 150 can rollably contact the top or bottom of the slide bar 1330 or the bottom wall 1155 or the top wall 1153 of the groove through the connecting port 170, and helps to reduce the space occupied by the annular groove 1190 in the horizontal direction X.

[0084] As another example, the connection port 170 can be provided on the annular end wall 1201 and the outer annular wall 1197. That is, the annular end wall 1201 and the outer annular wall 1197 can share a connection port 170. Understandably, the connection port 170 is located approximately in the boundary area between the annular end wall 1201 and the outer annular wall 1197. The annular track of the annular groove 1190 can be inclined relative to the horizontal plane. This facilitates providing an inclined raceway for the rolling element 150, which helps the rolling element 150 to roll more smoothly in the annular groove 1190.

[0085] In some embodiments, at least one of the first slider 115 and the second slider 133 may be provided with a cavity 1210 and a mounting cover 1230, the mounting cover 1230 being used to close and open the cavity 1210.

[0086] As an example, the first slider 115 may be provided with a cavity 1210 and a mounting cover 1230.

[0087] As another example, the second slider 133 may be provided with a cavity 1210 and a mounting cover 1230.

[0088] As another example, the first slider 115 may be provided with a cavity 1210 and a mounting cover 1230, and the second slider 133 may also be provided with a cavity 1210 and a mounting cover 1230.

[0089] The cavity 1210 may have an open first cavity opening 1211, a cavity peripheral wall, and a cavity end wall.

[0090] The cavity end wall and the first cavity opening 1211 can be spaced apart and opposite each other, and the cavity peripheral wall can extend from the first cavity opening 1211 to the cavity end wall.

[0091] An annular groove 1190 can be formed inside the cavity 1210.

[0092] The first cavity 1211 is used to allow the rolling element 150 to be installed in the annular groove 1190, so that multiple rolling elements 150 can be installed in the annular groove 1190 from the first cavity 1211, which makes it easier to assemble the rolling elements 150.

[0093] The mounting cover 1230 can be placed over the first cavity 1211, thereby closing the first cavity 1211 to confine the rolling element 150 within the annular groove 1190, which helps to prevent the rolling element 150 from dislodging from the annular groove 1190.

[0094] The cavity 1210 may be provided with a boss 1213 protruding from the cavity end wall toward the first cavity opening 1211. The outer peripheral wall of the boss 1213 and the cavity peripheral wall are spaced apart. The cavity peripheral wall can form an outer ring wall 1197, and the outer peripheral wall of the boss 1213 forms an inner ring wall 1199, thereby forming an annular groove 1190 in the cavity 1210.

[0095] It should be noted that the cavity peripheral wall can be partially formed as an outer ring wall 1197, or the cavity peripheral wall can be entirely formed as an outer ring wall 1197. Similarly, the outer peripheral wall of the boss 1213 can be partially formed as an inner ring wall 1199, or the entire outer ring wall 1199 can be formed as an inner ring wall 1199.

[0096] In some embodiments, the first slider 115 may be formed with a groove 1150, the second slider 133 may be formed with a strip 1330, and the first slider 115 may be provided with an annular groove 1190.

[0097] The bottom wall 1155 and / or the top wall 1153 of the drawer are provided with a connecting opening 170. At least one of the multiple rolling elements 150 can rollably contact the bottom and / or the top of the slide bar 1330 through the connecting opening 170. Thus, when the drawer 130 moves relative to the cabinet 110, the bottom and / or the top of the slide bar 1330 are supported by the rolling element 150, which helps to reduce the sliding contact friction between the bottom of the slide bar 1330 and the bottom wall 1155 of the drawer, and / or reduce the sliding contact friction between the top of the slide bar 1330 and the top wall 1153 of the drawer, thereby improving the smoothness of the drawer 130 movement.

[0098] As an example, the annular groove 1190 may include a first annular groove 1191, the connecting port 170 may include a first connecting port 171, and the plurality of rolling elements 150 may include a plurality of first rolling elements 151. The first sliding element 115 may be provided with the first annular groove 1191 and the first connecting port 171, and the first connecting port 171 may be provided through the bottom wall 1155 of the groove to connect the first annular groove 1191 and the sliding groove 1150. The plurality of first rolling elements 151 are rotatably disposed in the first annular groove 1191, and at least one of the first rolling elements 151 has its top exposed in the sliding groove 1150 through the first connecting port 171 and rotatably contacts the bottom of the slide bar 1330.

[0099] As another example, the annular groove 1190 may include a second annular groove 1193, the connecting port 170 may include a second connecting port 173, and the plurality of rolling elements 150 may include a plurality of second rolling elements 153. The first sliding element 115 may be provided with a second annular groove 1193 and a second connecting port 173, and the second connecting port 173 may be provided through the top wall 1153 of the groove to connect the second annular groove 1193 and the sliding groove 1150. The plurality of second rolling elements 153 are rotatably disposed in the second annular groove 1193, and at least one of the second rolling elements 153 has its bottom exposed in the sliding groove 1150 through the second connecting port 173 and rotatably contacts the top of the slide bar 1330.

[0100] As another example, the first sliding member 115 may be provided with a first annular groove 1191, a first connecting port 171, a second annular groove 1193 and a second connecting port 173. The multiple rolling members 150 may simultaneously include multiple first rolling members 151 and multiple second rolling members 153. The specific configuration can be referred to the above example, and will not be repeated here.

[0101] It should be noted that the specific structure and arrangement of the first annular groove 1191 and the second annular groove 1193 can refer to the annular groove 1190 in the above embodiment, and will not be repeated here.

[0102] Understandably, the second slider 133 may also be provided with an annular groove 1190. For details, please refer to [link / reference needed]. Figure 4 , Figure 7 and Figure 8 In some embodiments, the first slider 115 may be formed with a groove 1150, the second slider 133 may be formed with a slider strip 1330, and the second slider 133 may be provided with an annular groove 1190.

[0103] The bottom and / or top of the slide bar 1330 may be provided with a connecting port 170. At least one of the multiple rolling elements 150 can rollably contact the bottom wall 1155 and / or the top wall 1153 of the groove through the connecting port 170. In this way, the rolling element 150 can also support the slide bar 1330 from the bottom and / or top, which helps to reduce the sliding contact friction between the bottom of the slide bar 1330 and the bottom wall 1155 of the groove, and / or reduce the sliding contact friction between the top of the slide bar 1330 and the top wall 1153 of the groove.

[0104] As an example, the annular groove 1190 may include a third annular groove 1195, the connecting port 170 may include a third connecting port 175, and the plurality of rolling elements 150 may include a plurality of third rolling elements 155. The second sliding element 133 may be provided with a third annular groove 1195 and a third connecting port 175, and the third connecting port 175 may extend through the bottom of the slide bar 1330 to connect the third annular groove 1195 and the slide groove 1150. The plurality of third rolling elements 155 are rotatably disposed within the third annular groove 1195, and the bottom of at least one third rolling element 155 is exposed through the third connecting port 175 to the bottom of the slide bar 1330 and rotatably contacts the bottom wall 1155 of the groove.

[0105] As another example, the annular groove 1190 may include a fourth annular groove, the connecting port 170 may include a fourth connecting port, and the plurality of rolling elements 150 may include a plurality of fourth rolling elements. The second sliding element 133 may be provided with a fourth annular groove and a fourth connecting port, the fourth connecting port being provided through the top of the slide bar 1330 to connect the fourth annular groove and the slide groove 1150. The plurality of fourth rolling elements are rotatably disposed in the fourth annular groove, and at least one of the fourth rolling elements has its top exposed through the fourth connecting port to the top of the slide bar 1330, and rotatably contacts the top wall 1153 of the groove.

[0106] Please see Figures 3 to 4 In some embodiments, the first slider 115 may be formed with a slide bar 1330, the second slider 133 may be formed with a slide groove 1150, and the first slider 115 may be provided with an annular groove 1190.

[0107] The bottom and / or top of the slide bar 1330 are provided with a connecting opening 170. At least one of the multiple rolling elements 150 protrudes from the slide groove 1150 through the connecting opening 170 and can roll in contact with the bottom wall 1155 and / or the top wall 1153 of the groove. Thus, when the drawer 130 moves relative to the cabinet 110, the bottom wall 1155 and / or the top wall 1153 of the groove supports the rolling element 150, which helps to reduce the sliding contact friction between the bottom wall 1155 and the bottom of the slide bar 1330, and / or reduce the sliding contact friction between the top wall 1153 and the top of the slide bar 1330, thereby improving the smoothness of the drawer 130 movement.

[0108] Specifically, refer to the embodiment described above where the first sliding member 115 has a groove 1150, the second sliding member 133 has a slide bar 1330, and the second sliding member 133 has an annular groove 1190. The only difference is that in this embodiment, the first sliding member 115 has a slide bar 1330, while the second sliding member 133 has a groove 1150.

[0109] In some embodiments, the first slider 115 is formed with a slide bar 1330, the second slider 133 is formed with a slide groove 1150, and the second slider 133 is provided with an annular groove 1190.

[0110] The bottom wall 1155 and / or the top wall 1153 of the groove can be provided with a connecting opening 170. At least one of the multiple rolling elements 150 protrudes from the groove 1150 through the connecting opening 170 and can roll in contact with the bottom and / or top of the slide bar 1330. In this way, the rolling element 150 can also support the second slide bar 133 from the bottom wall 1155 and / or the top wall 1153 of the groove, which helps to reduce the sliding contact friction between the bottom of the slide bar 1330 and the bottom wall 1155 of the groove, and / or reduce the sliding contact friction between the top of the slide bar 1330 and the top wall 1153 of the groove, thereby improving the smoothness of the drawer 130 movement.

[0111] Specifically, refer to the embodiment described above where the first sliding member 115 has a groove 1150, the second sliding member 133 has a slide bar 1330, and the first sliding member 115 has an annular groove 1190. The only difference is that in this embodiment, the first sliding member 115 has a slide bar 1330, while the second sliding member 133 has a groove 1150.

[0112] Please see Figures 1 to 2 In some embodiments, the box body may be provided with a receiving cavity 111, and the receiving cavity 111 may have an open second cavity 113.

[0113] The drawer 130 can move from the second cavity opening 113 toward the receiving cavity 111 to move into the receiving cavity 111, and can move from the receiving cavity 111 toward the second cavity opening 113 to move to a position partially outside the receiving cavity 111.

[0114] Specifically, drawer 130 has an open position (such as...) Figure 2 (as shown) and closing position (as shown) Figure 1 (As shown). When drawer 130 is in the open position, part of drawer 130 is located outside the receiving cavity 111 to facilitate the retrieval or storage of items; when drawer 130 is in the closed position, drawer 130 is located inside the receiving cavity 111 to close drawer 130.

[0115] The drawer 130 can be moved from the receiving cavity 111 toward the second cavity opening 113 to the open position, and can be moved from the second cavity opening 113 toward the receiving cavity 111 to the closed position.

[0116] In some embodiments, the continuous extension length of the slide groove 1150 and the continuous extension length of the slide bar 1330 can both be greater than half the concave depth of the receiving cavity 111 from the second cavity opening 113 into the housing 110. This ensures that the bottom and top of the slide bar 1330, the top wall 1153 and the side wall 11574 of the slide groove 1150 can all have a sufficiently large extension length to provide a sufficiently long rolling surface for the rolling element 150, ensuring that the rolling element 150 has a sufficient rolling stroke so that the drawer 130 can move stably to the open and closed positions.

[0117] Please see Figure 1 , Figure 3 , Figure 5 In some embodiments, the first sliding member 115 may be provided with a first mounting portion 1250, which may be located at one end of the first sliding member 115 near the second cavity 113 (i.e., the third end 1161 of the slide groove 1150). The first mounting portion 1250 may be provided with an annular groove 1190 and a connecting port 170.

[0118] As an example, the first sliding member 115 has a groove 1150, the first mounting portion 1250 can partially protrude from the bottom wall 1155 of the groove into the groove 1150, the first annular groove 1191 can be provided in the first mounting portion 1250, and the first connecting port 171 can be provided through the top of the first mounting portion 1250, connecting the first annular groove 1191 and the groove 1150. At least one of the plurality of first rolling members 151 has its top protruding through the first connecting port 171 into the groove 1150 and can rollably contact the bottom of the slide bar 1330.

[0119] Please see Figure 1 , Figure 4 and Figure 8 The second sliding member 133 is provided with a second mounting part 1350. The second mounting part 1350 is located at one end of the second sliding member 133 from the second cavity opening 113 toward the receiving cavity 111 (i.e., the second end 1335 of the slide bar 1330). The second mounting part 1350 may also be provided with an annular groove 1190 and a connecting port 170.

[0120] As an example, the second sliding member 133 may be formed with a slide bar 1330, the second mounting portion 1350 may be disposed on the slide bar 1330 and partially protrude from the bottom of the slide bar 1330, the third annular groove 1195 may be disposed on the second mounting portion 1350, and the third connecting port 175 may be disposed through the bottom of the second mounting portion 1350, and the third connecting port 175 may connect the third annular groove 1195 and the slide groove 1150. At least one of the plurality of third rolling members 155 has its bottom protruding from the bottom of the slide bar 1330 through the third connecting port 175 and can rollably contact the bottom wall 1155 of the groove.

[0121] Please see Figures 2 to 4 The first mounting part 1250 is partially located in the movement path of the second mounting part 1350 and is used to block the second mounting part 1350 when the drawer 130 is in the open position. Thus, the first mounting part 1250 can limit the movement of the drawer 130 toward the second cavity opening 113 by limiting the movement of the second mounting part 1350 toward the second cavity opening 113. This reduces the occurrence of the drawer 130 leaving the receiving cavity 111, improves the stability of the drawer 130 during use, and enhances the user experience.

[0122] As an example, the first slider 115 has a groove 1150, and the second slider 133 has a slide bar 1330. The slide bar 1330 may have opposing first ends 1333 and second ends 1335 along the direction of movement of the drawer 130 (e.g., Figure 5 As shown), the slide 1150 has opposing third ends 1161 and fourth ends 11634 along the moving direction of the drawer 130 (as shown). Figure 7 (As shown).

[0123] When drawer 130 is in the closed position, the first end 1333 can be located inside the third end 1161, and the second end 1335 can be located inside the fourth end 1163. When drawer 130 is in the open position, the first end 1333 can be located outside the slide rail 1150, and the second end 1335 can be located inside the third end 1161.

[0124] The first mounting portion 1250 can be disposed at one end of the first sliding member 115 at the third end 1161 of the slide groove 1150, and the second mounting portion 1350 can be disposed at the second end 1335 of the slide bar 1330. When the drawer 130 moves from the closed position to the open position, the first mounting portion 1250 blocks the second mounting portion 1350 to limit the travel of the second mounting portion 1350 toward the second cavity opening 113, thereby limiting the travel of the drawer 130 toward the second cavity opening 113, thereby improving the situation where the drawer 130 moves out of the receiving cavity 111.

[0125] It should be noted that the structures of the first mounting part 1250 and the second mounting part 1350 can be roughly the same, and each annular groove 1190 can be disposed on the first sliding member 115 or the second sliding member 133 by being disposed on the mounting part (first mounting part 1250 or second mounting part 1350).

[0126] In some embodiments, the second mounting portion 1350 is provided with a clearance ramp. The clearance ramp connects the end face of the second mounting portion 1350 away from the second cavity 113 and the bottom surface of the second mounting portion 1350. A clearance space can be formed between the clearance ramp and the bottom wall 1155 of the groove. When the drawer 130 is in the open position, the user can lift the drawer 130. The clearance space can provide downward rotation space for the clearance ramp, which helps the user to lift the drawer 130 smoothly, so that the second mounting portion 1350 can rotate upward to overcome the obstruction of the first mounting portion 1250, thereby making it easy to remove the drawer 130 from the box 110.

[0127] Please see Figures 3 to 4 In some embodiments, the bottom of the slide bar 1330 may be recessed with a first raceway groove 1331. The first raceway groove 1331 may extend along the length of the slide groove 1150 and rollably contact the rolling element 150 of the slide bar 1330. The rolling element 150 may rollably contact the inner wall of the first raceway groove 1331, thereby providing an accurate raceway for the rolling element 150. The inner wall of the first raceway groove 1331 may also limit the swaying of the drawer 130 in the horizontal direction X by restricting the rolling element 150, which helps the drawer 130 move more smoothly and stably.

[0128] As an example, at least one of the plurality of first rolling elements 151 disposed in the first annular groove 1191 has its top protruding from the first connecting port 171 into the slide groove 1150 and can roll in contact with the inner wall of the first raceway groove 1331.

[0129] In some embodiments, the top of the slide bar 1330 is recessed with a first raceway groove 1331, which extends along the length of the slide groove 1150 and can rollably contact the rolling element 150 of the slide bar 1330. The rolling element 150 can rollably contact the inner wall of the first raceway groove 1331, so that the first raceway groove 1331 can provide an accurate raceway for the rolling element 150. The inner wall of the first raceway groove 1331 can also limit the swaying of the drawer 130 in the horizontal direction X by restricting the rolling element 150, which helps the drawer 130 move more smoothly and stably.

[0130] As an example, at least one of the plurality of second rolling elements 153 disposed in the second annular groove 1193 has its bottom protruding from the second connecting port 173 into the slide groove 1150 and can roll in contact with the inner wall of the first raceway groove 1331.

[0131] In some embodiments, the bottom wall 1155 of the groove may be recessed with a second raceway groove 1159. The second raceway groove 1159 may extend along the length direction of the slide groove 1150. The rolling element 150, which is rollably in contact with the inner wall of the slide groove 1150, may also rollably contact the inner wall of the second raceway groove 1159. Thus, the second raceway groove 1159 can provide an accurate raceway for the rolling element 150. The inner wall of the second raceway groove 1159 can also limit the wobbling of the drawer 130 in the horizontal direction X by restricting the rolling element 150, which helps the drawer 130 move more smoothly and stably.

[0132] As an example, at least one of the plurality of third rolling elements 155 disposed in the third annular groove 1195 has its bottom protruding from the third connecting port 175 into the slide groove 1150 and can roll in contact with the inner wall of the second raceway groove 1159.

[0133] In some embodiments, the top wall 1153 of the groove may be recessed with a second raceway groove 1159. The second raceway groove 1159 may extend along the length direction of the slide groove 1150. The rolling element 150, which is rollably in contact with the inner wall of the slide groove 1150, may also rollably contact the inner wall of the second raceway groove 1159. Thus, the second raceway groove 1159 can provide an accurate raceway for the rolling element 150. The inner wall of the second raceway groove 1159 can also limit the wobbling of the drawer 130 in the horizontal direction X by restricting the rolling element 150, which helps the drawer 130 move more smoothly and stably.

[0134] As an example, at least one of the plurality of fourth rolling elements disposed in the fourth annular groove has its top protruding from the third communication port 175 into the slide groove 1150 and rollingly contacting the inner wall of the second raceway groove 1159.

[0135] In some embodiments, at least one end of the first raceway groove 1331 recessed at the top of the slide bar 1330 and / or recessed at the bottom of the slide bar 1330 is flared along the length direction, so that when the drawer 130 is installed in the housing 110, the flared opening can guide the rolling element 150 into the first raceway groove 1331, which helps the rolling element 150 to enter the first raceway groove 1331 more easily and reduces the installation difficulty of the drawer 130.

[0136] As an example, the first sliding member 115 on the cabinet 110 can be formed with a slide bar 1330. The bottom of the slide bar 1330 can be recessed with a first raceway groove 1331. The end of the first raceway groove 1331 near the second cavity opening 113 along its length is flared. Then, the second sliding member 133 on the drawer 130 can be formed with a slide groove 1150. When the drawer 130 is installed on the cabinet 110, the flared opening can guide the rolling member 150, which is partially protruding from the bottom wall 1155 of the slide groove 1150, into the first rolling groove.

[0137] As another example, the second slider 133 on the drawer 130 can be formed with a slide bar 1330. The top of the slide bar 1330 can be recessed with a first raceway groove 1331. The end of the first raceway groove 1331 facing the second cavity opening 113 into the receiving cavity 111 can be flared. Then, the first slider 115 on the cabinet 110 can be formed with a track 1150. When the drawer 130 is installed on the cabinet 110, the flared opening can guide the rolling element 150, which is partially protruding from the top wall 1153 of the track 1150, into the first track track.

[0138] In some embodiments, at least one end of the second raceway groove 1159 recessed in the top wall 1153 and / or recessed in the bottom wall 1155 of the groove is provided in a flared shape along the length direction, so that when the drawer 130 is installed in the housing 110, the flared shape can guide the rolling element 150 into the second raceway groove 1159, which helps the rolling element 150 to enter the second raceway groove 1159 more easily and reduces the difficulty of installing the drawer 130.

[0139] As an example, the first sliding member 115 on the cabinet 110 has a groove 1150. The bottom wall 1155 of the groove 1150 may be recessed with a second raceway groove 1159. The end of the second raceway groove 1159 near the second cavity opening 113 along its length is flared. The second sliding member 133 on the drawer 130 may have a slide bar 1330. When the drawer 130 is installed on the cabinet 110, the flared opening can guide the rolling member 150, which is partially protruding from the bottom of the slide bar 1330, into the second raceway groove 1159.

[0140] As another example, the second slider 133 on the drawer 130 can be formed with a groove 1150. The top wall 1153 of the groove 1150 can be recessed with a second raceway groove 1159. The end of the second raceway groove 1159 facing the second cavity opening 113 into the receiving cavity 111 can be flared. Then, the first slider 115 on the cabinet 110 can be formed with a slide bar 1330. When the drawer 130 is installed on the cabinet 110, the flared opening can guide the rolling element 150, which is partially protruding from the top of the slide bar 1330, into the second raceway groove 1159.

[0141] In some embodiments, the rolling element 150 can be a ball, which can be spherically arranged to help the rolling element 150 roll more smoothly.

[0142] In some embodiments, the first raceway groove 1331 may include a second groove 1337, a first raceway wall 1339, a second raceway wall 1341, and a third raceway wall 1343.

[0143] The second groove 1337 and the first raceway wall 1339 can be vertically spaced relative to each other, and the second raceway wall 1341 and the third raceway wall 1343 can be spaced relative to each other and both extend from the second groove 1337 to the first raceway wall 1339. The rolling element 150, which is rollably in contact with the inner wall of the first raceway groove 1331, can also rollably contact the first raceway wall 1339. The first raceway wall 1339 can provide a stable raceway surface for the rolling element, which helps the rolling element 150 to roll stably.

[0144] The first raceway wall 1339 can be arranged in a straight line, that is, the wall surface of the first raceway wall 1339 is arranged in a plane, which helps the rolling element 150 to roll more stably on the first raceway wall 1339.

[0145] The distance between the second roller wall 1341 and the third roller wall 1343 is greater than the diameter of the rolling element 150. This provides space for the rolling element 150 to move in the horizontal X direction between the second roller wall 1341 and the third roller wall 1343. This helps to prevent the rolling element 150 from getting stuck when multiple rolling elements 150 support the drawer 130, and helps the drawer 130 move more smoothly.

[0146] As an example, consider a first sliding member 115 with a groove 1150, a second sliding member 133 with a slider 1330, and a first raceway groove 1331 recessed at the bottom of the slider 1330. A second groove 1337 can be located vertically Z above the first raceway wall 1339, and the second raceway wall 1341 and the third raceway wall 1343 can be spaced apart horizontally X. At least two connecting openings 170 can extend through the bottom wall 1155 of the groove. Each connecting opening 170 has a rolling member 150 partially exposed outside the groove 1150, and both can rollably contact the first raceway wall 1339. The space between the second raceway wall 1341 and the third raceway wall 1343 provides space for each rolling member 150 partially exposed from the connecting opening 170 within the groove 1150 to move horizontally X.

[0147] In some embodiments, the second raceway groove 1159 may include a third groove 1165, a fourth raceway wall 1167, a fifth raceway wall 1169, and a sixth raceway wall 1171.

[0148] The third groove 1165 and the fourth raceway wall 1167 can be spaced apart and opposite each other, and the fifth raceway wall 1169 and the sixth raceway wall 1171 can be spaced apart and opposite each other, both extending from the third groove 1165 to the fourth raceway wall 1167. The rolling element 150, which is rollably in contact with the inner wall of the second raceway groove 1159, can also rollably contact the fourth raceway wall 1167. The fourth raceway wall 1167 can provide a stable raceway surface for the rolling element, which helps the rolling element 150 to roll stably.

[0149] The fourth raceway wall 1167 is flat, that is, the wall surface of the fourth raceway wall 1167 is flat, which helps the rolling element 150 to roll more stably on the fourth raceway wall 1167.

[0150] The distance between the fifth roller wall 1169 and the sixth roller wall 1171 is greater than the diameter of the rolling element 150. This provides space for the rolling element 150 to move in the horizontal X direction between the fifth roller wall 1169 and the sixth roller wall 1171. This helps to prevent the rolling element 150 from getting stuck when multiple rolling elements 150 support the drawer 130, and helps the drawer 130 move more smoothly.

[0151] As an example, consider a first sliding member 115 with a groove 1150, a second sliding member 133 with a slider 1330, and a second raceway groove 1159 recessed in the bottom wall 1155 of the groove. A third groove 1165 can be located vertically Z above a fourth raceway wall 1167, and a fifth raceway wall 1169 and a sixth raceway wall 1171 can be spaced apart horizontally X. At least two connecting openings 170 can extend through the bottom of the slider 1330. Each connecting opening 170 has a rolling member 150 partially exposed in the groove 1150, and both can rollably contact the fourth raceway wall 1167. The space between the fifth raceway wall 1169 and the sixth raceway wall 1171 provides space for the rolling member 150 partially exposed in the groove 1150 in each connecting opening 170 to move horizontally X.

One of the first sliding member 115 and the second sliding member 133 forms a groove 1150, and the other forms a slide bar 1330. The slide bar 1330 is at least partially inserted into the groove 1150, and the slide bar 1330 can move relative to the groove 1150 along the length direction of the groove 1150, so that the drawer 130 can move back and forth relative to the box body 110, and the drawer 130 can be opened and closed smoothly. Furthermore, an annular groove 1190 and a connecting opening 170 are provided on the first sliding member 115 and / or the second sliding member 133, and a plurality of rollable parts are provided in the annular groove 1190. The rolling element 150, at least one of which can rollably contact the inner wall of the slide bar 1330 and / or the groove 1150 through the communication port 170. In this way, the inner wall of the slide bar 1330 and the groove 1150 can be rolled together by the rolling element 150, which helps to reduce sliding friction and makes the drawer 130 move more smoothly and stably. In addition, compared with the use of metal split slide rails in related technologies, the storage device 100 provided in this application embodiment can directly integrate multiple rolling elements 150 into the annular groove 1190 of the sliding element (i.e., the first sliding element 115 or the second sliding element 133), simplifying the sliding structure between the drawer 130 and the box 110. The storage device 100 has a higher degree of integration and lower manufacturing cost.
