[0034] Please see Figures 1 to 3 This application provides a storage device 100, which can be a refrigerator, cabinet or other storage device 100.

[0035] The storage device 100 includes a box, a drawer 130, and a rolling element 150.

[0036] The box includes a box body and a first sliding member 110, and the drawer 130 includes a drawer body 131 and a second sliding member 133.

[0037] The inner wall of the box body is provided with two opposing first sliding members 110, and the outer wall of the drawer body 131 is provided with two opposing second sliding members 133. Each second sliding member 133 is slidably connected to a first sliding member 110 through a rolling member 150, which helps to avoid direct contact friction between the first sliding member 110 and the second sliding member 133, reduces the sliding friction when the drawer 130 moves, and helps the drawer 130 move more smoothly.

[0038] For ease of description, the following explanation will use a first slider 110 and a second slider 133 as an example.

[0039] The first slider 110 and the second slider 133 can be configured in various ways.

[0040] As an example, the two opposite inner sidewalls of the box are each provided with a first sliding member 110, and the two opposite outer sidewalls of the drawer body 131 are each provided with a slide bar 1331.

[0041] As another example, the inner bottom wall of the box is provided with two opposing first sliding members 110, and the bottom wall of the drawer body 131 is provided with two bent sliding strips 1331. The first sliding members 110 can be arranged in an L-shape to be slidably installed on the second sliding members 133.

[0042] The first sliding member 110 and / or the second sliding member 133 are provided with guide grooves 170. The rolling member 150 can roll in contact with the inner wall of the guide groove 170. The guide groove 170 extends along the moving direction of the drawer 130 to guide the rolling member 150 to roll along the moving direction of the drawer 130 when the drawer 130 moves. Thus, the guide groove 170 can provide a more definite rolling track for the rolling member 150, reducing the possibility of the rolling member 150 being misaligned or falling off, and helping the drawer 130 to move more stably.

[0043] The guide groove 170 is formed in the distribution direction of the two first sliding members 110, which allows the rolling member 150 to move relative to the guide groove 170 in that direction. So when the drawer 130 shakes left and right, the rolling member 150 can move laterally to adapt to the shaking of the drawer 130, which helps to avoid the rolling member 150 getting stuck. In addition, it can also reduce the situation where the rolling member 150 gets stuck in the guide groove 170 due to manufacturing errors or installation errors, thus improving the fault tolerance rate.

[0044] The distribution direction of the two first sliding members 110 is approximately perpendicular to the moving direction of the drawer 130. The lateral movement of the rolling member 150 can refer to the movement of the rolling member 150 in the distribution direction of the first sliding members 110.

[0045] The displacement of the rolling element 150 in the guide groove 170 can refer to the rolling element 150 rolling or moving in the distribution direction of the two first sliding elements 110 to cause displacement.

[0046] Please see Figures 3 to 5 In some embodiments, the guide groove 170 may include a first groove 173, a second groove 175, a rolling wall 177, and a limiting wall 179.

[0047] The first slot 173 and the rolling wall 177 can be vertically spaced relative to each other.

[0048] As an example, the second slider 133 can be disposed above the first slider 110, and the bottom of the second slider 133 is slidably connected to the top of the first slider 110 via a rolling element 150. The top of the first slider 110 can support the bottom of the second slider 133 via the rolling element 150. The top of the first slider 110 may be provided with a guide groove 170, and the first opening 173 in the guide groove 170 may be located above the rolling wall 177; and / or, the bottom of the second slider 133 may be provided with a guide groove 170, and the first opening 173 in the guide groove 170 may be located below the rolling wall 177.

[0049] The second slot 175 and the limiting wall 179 can be arranged at intervals relative to each other along the distribution direction of the two first sliding members 110, and a space can be formed between the first slot 173 and the limiting wall 179, so that the rolling member 150 can move between the second slot 175 and the rolling member 150.

[0050] The rolling element 150 can roll in contact with the rolling wall 177 along the moving direction of the drawer 130. The limiting wall 179 can be used to limit the movement of the rolling element 150 along the second groove 175 towards the limiting wall 179. Thus, the guide groove 170 can not only provide space for lateral displacement of the rolling element, but the limiting wall 179 can also limit the movement direction of the rolling element 150, which helps to improve the situation where the rolling element 150 disengages from the guide groove 170. Moreover, the limiting wall 179 can limit the left and right swaying of the drawer 130 by limiting the formation of the lateral movement of the rolling element 150, which helps the drawer 130 move more stably and smoothly.

[0051] The first slot 173 and the second slot 175 are interconnected, which helps to prevent the rolling element 150 from being interfered with by other structures between the first slot 173 and the second slot 175, so that the rolling element 150 can move smoothly between the second slot 175 and the limiting wall 179.

[0052] As an example, as described above, in the guide groove 170 of the first slider 110, the first groove 173 can be located on the top wall of the first slider 110, and the second groove 175 can be located on the side wall of the first slider 110. In the guide groove 170 of the second slider 133, the first groove 173 can be located on the bottom wall of the second slider 133, and the second groove 175 can be located on the side wall of the second slider 133.

[0053] In some embodiments, the box body may be provided with a receiving cavity, the receiving cavity may have an open opening, the drawer 130 may move from the opening into the receiving cavity to move to a closed position, and may move from the receiving cavity towards the opening to move to an open position.

[0054] The two first sliding members 110 can be integrally formed on the two opposite inner sidewalls of the accommodating cavity, so that the first sliding members 110 do not need to be installed separately on the box body, which helps to reduce the manufacturing cost of the box body, reduces the number of parts of the storage device 100, and helps to simplify the assembly process of the storage device 100.

[0055] As an example, the box body and the first sliding member 110 can be vacuum-formed into a single integrated structure, or the box body and the first sliding member 110 can also adopt other integrated molding processes.

[0056] At least one of the two first sliding members 110 may be provided with a guide groove 170, thereby providing space for guiding and lateral movement of the rolling member 150.

[0057] The second slot 175 can be provided on the side wall of the first sliding member 110 facing the accommodating cavity, so that the guide slot 170 is open on both the vertical side and the width side, which facilitates the demolding of the guide slot 170 when manufacturing the box and reduces the manufacturing difficulty of the box.

[0058] As an example, the second slot 175 may be provided on the side wall of the first slider 110 facing the other first slider 110.

[0059] The width direction of the guide groove 170 is approximately the same as the distribution direction of the two first sliding members 110.

[0060] In some embodiments, the two second sliding members 133 can be integrally formed on the opposite two outer side walls of the drawer body 131, 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.

[0061] As an example, the drawer body 131 and the second sliding member 133 can be injection molded into a single-piece structure, or the drawer body 131 and the second sliding member 133 can also adopt other single-piece molding processes.

[0062] At least one of the two second sliders 133 is provided with a guide groove 170, thereby providing space for guiding and lateral movement of the rolling element 150.

[0063] The second slot 175 can be provided on the side wall of the second sliding member 133 facing away from the drawer body 131, so that the guide slot 170 is open on both the vertical side and the width side, which makes it easier to demold the guide slot 170 when manufacturing the drawer 130 and reduces the manufacturing difficulty of the drawer 130.

[0064] In some embodiments, the guide groove 170 may be either a first groove type or a second groove type.

[0065] As an example, when both the first slider 110 and the second slider 133 are provided with guide grooves 170. The guide grooves 170 on the first slider 110 and the guide grooves 170 on the second slider 133 can be of the same groove type or different groove types (e.g., Figure 4 and Figure 5 (As shown).

[0066] In the first slot type (e.g.) Figure 5 The third guide groove 185 in the middle) and the limiting wall 179 can extend in the vertical direction, which helps the limiting wall 179 to more stably limit the lateral movement of the rolling element 150.

[0067] The rolling wall 177 can extend horizontally along the distribution direction of the two first sliding members 110, so that the wall surface of the rolling wall 177 can be set in a plane, which helps the rolling member 150 to roll more stably on the rolling wall 177.

[0068] As an example, the limiting wall 179 can extend vertically from the side of the first slot 173 away from the second slot 175 to the rolling wall 177. Correspondingly, the rolling wall 177 can extend laterally from the side of the second slot 175 away from the first slot 173 to the limiting wall 179. The rolling wall 177 and the limiting wall 179 can be connected at approximately a right angle.

[0069] As another example, unlike the previous example, the guide groove 170 may also include a connecting wall, which can be connected between the limiting wall 179 and the rolling wall 177. The shape of the connecting wall can be set according to the requirements. For example, the connecting wall can be an inclined wall or an arc wall.

[0070] In the second type of channel (e.g.) Figure 5 The first guide groove 181), the limiting wall 179 can be an arc wall, and the rolling wall 177 can extend horizontally along the distribution direction of the two first sliding members 110. In this way, the limiting wall 179 can provide buffer for the rolling member 150 when it moves laterally, which can improve the rigid impact between the limiting wall 179 and the rolling member 150. The limiting wall 179 can not only restrict the lateral movement of the rolling member 150, but also reduce the noise generated by the rigid impact, improve the damage of the rolling member 150, and help extend the service life of the rolling member 150.

[0071] In some embodiments, in the second groove type, the limiting wall 179 can be an arc wall with a central angle less than or equal to 90°, that is, the limiting wall 179 is approximately an arc wall less than or equal to 1 / 4 of a circle, which helps to further enhance the cushioning effect provided by the limiting wall 179 for the rolling element 150.

[0072] In some embodiments, one of the first slider 110 and the second slider 133 is formed with a slide bar 1331, and the other is formed with a slide groove 111.

[0073] The chute 111 may include a third groove opening 1111, a bottom wall 1113, a top wall 1115, and a side wall 1117.

[0074] The third slot 1111 and the slot sidewall 1117 are spaced apart and opposite each other.

[0075] As an example, the slot sidewall 1117 and the third slot 1111 can be spaced apart and opposite each other along the distribution direction of the two first sliding members 110, and the drawer body 131 and the slot sidewall 1117 can be located on opposite sides of the third slot 1111 in the distribution direction of the two first sliding members 110.

[0076] The bottom wall 1113 can extend from the bottom of the third opening 1111 to the side wall 1117, and the top wall 1115 can extend from the top of the third opening 1111 to the side wall 1117. That is, the top wall 1115 and the bottom wall 1113 are spaced apart and opposite each other, and the top wall 1115 can be located above the bottom wall 1113 in the vertical direction.

[0077] The slide bar 1331 is at least partially inserted into the slide groove 111 through the third slot 1111 and can move along the length of the slide groove 111. Thus, the bottom wall 1113 of the groove can directly or indirectly support the bottom of the slide bar 1331, and the top wall 1115 of the groove can directly or indirectly support the top of the slide bar 1331. This helps to reduce the possibility of the drawer 130 tipping over or tilting, and makes the movement of the drawer 130 more stable.

[0078] The top wall 1115, bottom wall 1113, and side wall 1117 of the drawer can all have gaps with the slide bar 1331 to reduce sliding friction and reduce the resistance to the drawer movement, making the drawer 130 move more smoothly.

[0079] In some embodiments, the bottom of the slide bar 1331 and the bottom wall of the groove 1113 can be slidably connected by a roller 150. The bottom wall of the groove 1113 can indirectly support the bottom of the slide bar 1331 by the roller 150, which helps to avoid direct contact and friction between the bottom of the slide bar 1331 and the bottom wall of the groove 1113, and helps the drawer 130 move more easily and make it easier to take things out.

[0080] At least one of the bottom of the slide bar 1331 and the bottom wall 1113 of the groove is recessed with a guide groove 170 to provide space for guiding and lateral movement of the rolling element 150.

[0081] Each guide groove 170 can be either a first groove type or a second groove type.

[0082] In some embodiments, the rolling element 150 may include a first rolling element 151, and the guide groove 170 may include a first guide groove 181 and a second guide groove 183.

[0083] It should be noted that the first guide groove 181 and the second guide groove 183 can both refer to the guide groove 170 in the above embodiment. Specifically, there are two guide grooves 170, namely the first guide groove 181 and the second guide groove 183.

[0084] The first guide groove 181 can be recessed at the bottom of the slide bar 1331, and the second guide groove 183 can be recessed at the bottom wall 1113 of the groove. The first rolling element 151 is rotatably disposed between the first guide groove 181 and the second guide groove 183, so that the first guide groove 181 and the second guide groove 183 can provide guidance for the first rolling element 151 from above and below, respectively, which helps the first rolling element 151 to have a more defined rolling track.

[0085] Specifically, the top of the first rolling element 151 can rollably contact the rolling wall 177 of the first guide groove 181, and the bottom can rollably contact the rolling wall 177 of the second guide groove 183.

[0086] The limiting wall 179 of the first guide groove 181 and the limiting wall 179 of the second guide groove 183 can be located on opposite sides of the first rolling member 151 in the distribution direction of the two first sliding members 110. Thus, the two limiting walls 179 can limit the first rolling member 151 on the left and right sides respectively, which helps to restrict the first rolling member 151 between the two limiting walls 179 and further reduces the possibility of the first rolling member 151 derailing.

[0087] Both the first guide groove 181 and the second guide groove 183 can adopt either the first groove type or the second groove type, and can be flexibly combined according to the requirements.

[0088] As an example, both the first guide groove 181 and the second guide groove 183 can adopt the first groove type.

[0089] As another example, both the first guide groove 181 and the second guide groove 183 can adopt the second groove type.

[0090] As another example, one of the first guide groove 181 and the second guide groove 183 may adopt the first groove type, and the other may adopt the second groove type.

[0091] In some embodiments, the top of the slide bar 1331 and the top wall 1115 of the groove can be slidably connected by a roller 150, and the top wall 1115 of the groove can be indirectly supported on the top of the slide bar 1331 by the roller 150, thereby reducing the possibility of the drawer 130 tipping over or tilting.

[0092] At least one of the top of the slide bar 1331 and the top wall of the groove 1115 may be recessed with a guide groove 170 to provide space for guiding and lateral movement of the rolling element 150.

[0093] Each guide groove 170 can be either a first groove type or a second groove type.

[0094] In some embodiments, the rolling element 150 may include a second rolling element 153, and the guide groove 170 may include a third guide groove 185 and a fourth guide groove 187.

[0095] It should be noted that the third guide groove 185 and the fourth guide groove 187 can both refer to the guide groove 170 in the above embodiment. Specifically, there are four guide grooves 170, namely the first guide groove 181, the second guide groove 183, the third guide groove 185 and the fourth guide groove 187.

[0096] The third guide groove 185 can be recessed in the top of the slide bar 1331, and the fourth guide groove 187 can be recessed in the top wall 1115 of the groove. The second rolling element 153 can be rolled between the third guide groove 185 and the fourth guide groove 187, so that the third guide groove 185 and the fourth guide groove 187 can provide guidance for the second rolling element 153 from below and above, respectively, which helps the second rolling element 153 to have a more defined rolling track.

[0097] Specifically, the bottom of the second rolling element 153 can rollably contact the rolling wall 177 of the third guide groove 185, and the top can rollably contact the rolling wall 177 of the fourth guide groove 187.

[0098] The limiting wall 179 of the third guide groove 185 and the limiting wall 179 of the fourth guide groove 187 can be located on opposite sides of the second rolling member 153 in the distribution direction of the two first sliding members 110. Thus, the two limiting walls 179 can limit the second rolling member 153 on the left and right sides respectively, which helps to restrict the second rolling member 153 between the two limiting walls 179 and further reduces the possibility of the second rolling member 153 derailing.

[0099] The third guide groove 185 and the fourth guide groove 187 can both adopt either the first groove type or the second groove type, and can be flexibly combined according to the requirements.

[0100] As an example, both the third guide groove 185 and the fourth guide groove 187 can adopt the first groove type.

[0101] As another example, both the third guide groove 185 and the fourth guide groove 187 can adopt the second groove type.

[0102] As another example, one of the third guide groove 185 and the fourth guide groove 187 may adopt the first groove type, and the other may adopt the second groove type.

[0103] In some embodiments, the storage device 100 may include a first limiting strip 190, which may be disposed between the bottom of the slide bar 1331 and the bottom wall 1113 of the groove.

[0104] The first limiting strip 190 is inserted between the bottom of the slide bar 1331 and the bottom wall of the groove 1113. This means that the first limiting strip 190 is located between the bottom of the slide bar 1331 and the bottom wall of the groove 1113, and is spaced apart from the bottom of the slide bar 1331 and the bottom wall of the groove 1113 respectively, so as to reduce sliding friction.

[0105] The first rolling element 151 is rotatably mounted on the first limiting bar 190. The first rolling element 151 is used to drive the first limiting bar 190 to move along the moving direction of the drawer 130 when rolling. The first limiting bar 190 can further limit the position of the first rolling element 151.

[0106] Please see Figure 2 Hezhi Figure 4 In some embodiments, the number of first rolling elements 151 can be multiple, and the first limiting strip 190 can be provided with multiple first limiting through holes spaced apart along the length direction of the slide groove 111. Multiple can refer to two or more.

[0107] Each first rolling element 151 is rotatably mounted in a first limiting through hole, so that the bottom of the slide bar 1331 and the bottom wall 1113 of the groove can be supported by multiple first rolling elements 151. Multiple first rolling elements 151 can support the drawer 130 more stably, so as to transmit the weight of the drawer 130 to the bottom wall 1113 of the groove more evenly, which helps to reduce the possibility of the drawer 130 tipping over or tilting, and the drawer 130 moves more smoothly.

[0108] As an example, the top opening of the first limiting through hole can be smaller than the maximum outer diameter of the first rolling element 151, and the bottom opening of the first limiting through hole can also be smaller than the maximum outer diameter of the first rolling element 151. The portion of the maximum outer diameter of the first rolling element 151 can be set between the top opening and the bottom opening of the first limiting through hole, so that the first rolling element 151 can be locked and installed in the first limiting through hole.

[0109] Understandably, the bottom of the first rolling element 151 may be exposed below the first limiting through hole to roll and contact the bottom wall 1113 of the groove or the rolling wall 177 of the second guide groove 183; the top of the first rolling element 151 may be exposed above the first limiting through hole to roll and contact the bottom of the slider 1331 or the rolling wall 177 of the first guide groove 181.

[0110] In some embodiments, the storage device 100 may further include a second limiting strip 210, which may be disposed between the top of the slide bar 1331 and the top wall 1115 of the groove.

[0111] The second limiting strip 210 is inserted between the top of the slide bar 1331 and the top wall of the groove 1115. This means that the second limiting strip 210 is located between the top of the slide bar 1331 and the top wall of the groove 1115, and is spaced apart from the top of the slide bar 1331 and the top wall of the groove 1115 respectively, so as to reduce sliding friction.

[0112] The second rolling element 153 is rotatably mounted on the second limiting bar 210. The second rolling element 153 can be used to drive the second limiting bar 210 to move along the moving direction of the drawer 130 when rolling. The second limiting bar 210 can further limit the position of the second rolling element 153.

[0113] In some embodiments, the number of second rolling elements 153 can be multiple, and the second limiting strip 210 can be provided with multiple second limiting through holes spaced apart along the length direction of the slide groove 111. Multiple can refer to two or more.

[0114] Each second roller 153 is rotatably mounted in a second limiting through hole, so that the top of the slide bar 1331 and the top wall 1115 of the groove can be supported by multiple second rollers 153, which helps to further reduce the possibility of the drawer 130 tipping over or tilting, and makes the drawer 130 move more smoothly.

[0115] In some embodiments, the storage device 100 may further include a vertical connecting strip 230, which may pass through the slide bar 1331 and the groove sidewall 1117.

[0116] As an example, the vertical connecting strip 230 can be spaced apart from the groove sidewall 1117 and from the slide bar 1331 to reduce sliding friction.

[0117] The first limiting strip 190 can extend laterally from the bottom end of the vertical connecting strip 230 and pass through the bottom of the slide 1331 and the bottom wall 1113 of the groove. The second limiting strip 210 can extend laterally from the top end of the vertical connecting strip 230 and pass through the top of the slide 1331 and the top wall 1115 of the groove. In this way, the vertical connecting strip 230 can connect the first limiting strip 190 and the second limiting strip 210, so that the first limiting strip 190 and the second limiting strip 210 can move synchronously. The first rolling element 151 and the second rolling element 153 can simultaneously drive the vertical connecting strip 230, the first limiting strip 190 and the second limiting strip 210 to move when rolling, which helps to make the movement smoother and more stable. In addition, the first rolling element 151 and the second rolling element 153 can support the slide 1331 at approximately the same position at the top and bottom, further making the movement of the drawer 130 smoother.

[0118] In some embodiments, the roller 150 can be a ball or a roller, which helps the roller 150 roll more stably and the drawer 130 move more smoothly.

[0119] As an example, both the first rolling element 151 and the second rolling element 153 can be ball bearings.

[0120] As another example, both the first rolling element 151 and the second rolling element 153 can be rollers.

[0121] As another example, one of the first rolling element 151 and the second rolling element 153 is a ball bearing, and the other is a roller bearing.

[0122] In the storage device 100 provided in this application embodiment, a rollable roller 150 is provided between the first slider 110 and the second slider 133, thereby avoiding direct contact friction between the first slider 110 and the second slider 133, reducing the sliding friction force when the drawer 130 moves, and helping the drawer 130 move more smoothly. By providing a guide groove 170 on the first slider 110 and / or the second slider 133, the roller 150 can roll in contact with the inner wall of the guide groove 170. The guide groove 170 can guide the roller 150 to roll along the moving direction of the drawer 130 when the drawer 130 moves, thereby providing a more definite rolling track for the roller 150, reducing the possibility of the roller 150 being misaligned or falling off, and helping the drawer 130 move more stably. Furthermore, the guide groove 170 can be formed in the distribution direction of the two first sliding members 110 to allow the rolling member 150 to move relative to the guide groove 170 in that direction, thereby reducing the situation where the rolling member 150 gets stuck in the guide groove 170 due to manufacturing or installation errors. When the drawer 130 shakes left and right, the rolling member 150 can move laterally to adapt to the shaking of the drawer 130, further improving the situation where the rolling member 150 gets stuck, and the drawer 130 moves more stably and smoothly.
