The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application and cannot be understood as a limitation of the present application.

[0044] A base assembly 1 according to an embodiment of the present application is described below with reference to the drawings.

[0045] As shown in the drawings, the base assembly 1 according to an embodiment of the present application comprises a base 10, a drawer 20 and a slide rail assembly 30. Figures 1-4

[0046] The base 10 defines a receiving cavity 11 having a side opening at one end in a first direction, and the drawer 20 is pullably arranged in the receiving cavity 11 from the side opening in the first direction, and the drawer 20 can be closed into the receiving cavity 11 or pulled out of the receiving cavity 11 by pulling the drawer 20.

[0047] The drawer 20 cooperates with the base 10 through the slide rail assembly 30, and the slide rail assembly 30 can guide the movement of the drawer 20, so that the drawer 20 can smoothly move in the first direction.

[0048] The slide rail assembly 30 comprises a first slide rail and a first pulley 32 in movable cooperation, the first slide rail extends in the first direction, one of the first slide rail and the first pulley 32 is arranged on the base 10, and the other is arranged on the drawer 20, when the drawer 20 moves in the first direction, the first pulley 32 moves in the first slide rail, so that the first pulley 32 and the first slide rail can smoothly move relative to each other in the first direction, and the drawer 20 can be smoothly pulled in the first direction.

[0049] The slide rail assembly 30 further comprises a second slide rail and a second pulley 42 in movable cooperation, the second slide rail extends in the first direction, one of the second slide rail and the second pulley 42 is arranged on the base 10, and the other is arranged on the drawer 20, when the drawer 20 moves in the first direction, the second pulley 42 moves in the second slide rail, so that the second pulley 42 and the second slide rail can smoothly move relative to each other in the first direction, and the drawer 20 can be smoothly pulled in the first direction.​

[0050] The first slide rail and the second slide rail are arranged along a second direction, and the second direction is perpendicular to the first direction. Through the corresponding cooperation of the two slide rails and the pulleys, the sliding of the drawer 20 in the first direction is guided. Compared with a single slide rail, on the one hand, the shaking range of the drawer 20 can be reduced, and on the other hand, the drawer can be smoothly and stably pulled out, and the smoothness of the drawer 20 during pulling out can be improved.

[0051] Therefore, the base assembly 1 has the advantages of improving the smoothness, stability, and reducing the shaking of the drawer 20 during pulling out.

[0052] The base assembly 1 according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0053] In some embodiments of the present application, as shown in Figures 1-4 The base assembly 1 comprises a base 10, a drawer 20, and a slide rail assembly 30.

[0054] In some embodiments of the present application, the first pulley 32 is movable in the first slide rail, which can be rolling cooperation or sliding cooperation between the first pulley 32 and the first slide rail, and no more limitation is made herein.

[0055] The second pulley 42 is movable in the second slide rail, which can be rolling cooperation or sliding cooperation between the second pulley 42 and the second slide rail, and no more limitation is made herein.

[0056] In some optional embodiments of the present application, the first pulley 32 can roll in the first slide rail. When the first pulley 32 rolls along the first slide rail, the resistance received by the first pulley 32 can be reduced. When the drawer 20 is pulled out in the first direction, the resistance received by the drawer 20 during movement can be reduced, and the smoothness of the drawer 20 during pulling out can be ensured, and the rough feeling of the drawer 20 during pulling out can be reduced.

[0057] In some optional embodiments of the present application, the second pulley 42 can roll in the second slide rail. When the second pulley 42 rolls along the second slide rail, the resistance received by the second pulley 42 can be reduced. When the drawer 20 is pulled out in the first direction, the resistance received by the drawer 20 during movement can be reduced, and the smoothness of the drawer 20 during pulling out can be ensured, and the rough feeling of the drawer 20 during pulling out can be reduced.

[0058] In some embodiments of the present application, as shown in Figure 1 , Figure 2As shown, the wheel shafts of the first pulley 32 and the second pulley 42 extend along the third direction, the first direction, the second direction and the third direction are perpendicular to each other, the extending directions of the wheel shafts of the first pulley 32 and the second pulley 42 are the same, so that when the drawer 20 is pulled to move along the first direction, the force of the first pulley 32 and the second pulley 42 is uniform, and the smoothness of the drawer 20 when moving along the first direction is improved.

[0059] In some embodiments of the utility model, as shown in Figure 2 、 Figure 7 As shown, the first sliding rail is arranged on the base 10, the wheel shaft of the first pulley 32 is arranged on the drawer 20, the first pulley 32 is supported on the first sliding rail to support the drawer 20 in the accommodating cavity 11, when the drawer 20 is pulled along the first direction, the first pulley 32 moves in the first sliding rail, and then supports the movement of the drawer 20 along the first direction, so that the drawer 20 can smoothly move along the first direction.

[0060] In addition, the first pulley 32 is arranged away from the drawer panel 22 of the drawer 20, so that when the drawer 20 is pulled along the first direction, the first pulley 32 can be hidden in the accommodating cavity 11, and the possibility of the first pulley 32 being exposed is reduced.

[0061] Specifically, when the drawer 20 is closed in the accommodating cavity 11, the drawer panel 22 closes the side opening, so that the articles in the accommodating cavity 11 are not exposed, and the appearance of the base assembly 1 is improved.

[0062] In some embodiments, the first pulley 32 is rotatably arranged on the drawer 20, and when the drawer 20 is pulled out, the first pulley 32 can roll in the first sliding rail.

[0063] In some optional embodiments of the utility model, as shown in Figure 2 The first sliding rail is suitable for defining the first sliding groove 31, and the first sliding groove 31 has the first upper groove wall 312 and the first lower groove wall 313 which are oppositely arranged along the second direction.

[0064] In some embodiments, in the first direction, at least a part of the first lower groove wall 313 extends downward along the direction close to the side opening, so that when the drawer 20 is pulled out of the accommodating cavity 11 along the first direction, under the action of gravity, the drawer 20 has a tendency to automatically move out of the accommodating cavity 11 along the first direction, so that the drawer 20 is conveniently and smoothly pulled out of the accommodating cavity 11, and the operation feeling and use experience are improved.

[0065] In some embodiments, at least a portion of the first lower groove wall 313 extends downwardly in a direction away from the side opening, so that when the drawer 20 is pushed into the receiving cavity 11 in the first direction, the drawer 20 has a tendency to move into the receiving cavity 11 in the first direction under the action of gravity, facilitating smooth pushing of the drawer 20 into the receiving cavity 11 and improving the operation feeling and user experience.

[0066] In some embodiments of the present application, the angle between the portion of the first lower groove wall 313 extending obliquely and the first direction is 0.5° to 10°, so as to control the angle of the oblique extension of the first lower groove wall 313.

[0067] The angle between the portion of the first lower groove wall 313 extending obliquely and the first direction is greater than or equal to 0.5°, so that when the drawer 20 is pushed or pulled, the gravity of the drawer 20 can be used to assist the movement of the drawer 20 in the first direction, thereby improving the feeling of the user when pushing or pulling the drawer 20 in the first direction and improving the user experience.

[0068] The angle between the portion of the first lower groove wall 313 extending obliquely and the first direction is less than or equal to 10°, so as to avoid excessive force on the drawer 20 itself, avoid excessive speed of the drawer 20 moving in the first direction when the drawer 20 is pushed or pulled in the first direction, and avoid excessive noise generated by the drawer 20 when moving in the first direction.

[0069] In some embodiments of the present application, as shown in Figure 2 The first upper groove wall 312 includes a first upper extension segment 3121, a second upper extension segment 3122 and a third upper extension segment 3123 arranged in the first direction, and the second upper extension segment 3122 connects the first upper extension segment 3121 and the third upper extension segment 3123. The first lower groove wall 313 includes a first lower extension segment 3131, a second lower extension segment 3132 and a third lower extension segment 3133 arranged in the first direction, and the second lower extension segment 3132 connects the first lower extension segment 3131 and the third lower extension segment 3133.

[0070] The first pulley 32 is supported on the first lower groove wall 313, thereby supporting the drawer 20 in the receiving cavity 11, so that the drawer 20 can move in the first direction in the receiving cavity 11.

[0071] The first upper extension section 3121 and the first lower extension section 3131 are oppositely arranged in the second direction and both extend along the first direction, and the third upper extension section 3123 and the third lower extension section 3133 are oppositely arranged in the second direction and both extend along the first direction, so that when the drawer 20 is pulled out along the first direction or is accommodated in the accommodating cavity 11 along the first direction, the first pulley 32 is located between the first upper extension section 3121 and the first lower extension section 3131 or between the third upper extension section 3123 and the third lower extension section 3133, the position of the first pulley 32 can be limited, and then the drawer 20 is limited at the position, so that the drawer 20 is prevented from moving due to the influence of its own gravity, and a safety hazard is avoided.

[0072] The second upper extension section 3122 and the second lower extension section 3132 are oppositely arranged in the second direction, and in the first direction, the second lower extension section 3132 extends downwardly away from the side opening, so that when the drawer 20 is pushed into the accommodating cavity 11 along the first direction, the gravity of the drawer 20 itself assists the drawer 20 to move away from the side opening along the first direction, so that the drawer 20 is conveniently and smoothly pushed into the accommodating cavity 11, the hand feeling of a user when pushing and pulling the drawer 20 along the first direction is improved, and the use experience of the user is improved.

[0073] In addition, the second lower extension section 3132 extends downwardly away from the side opening, so that when the drawer 20 is pulled out of the accommodating cavity 11 along the first direction, the resistance caused by the gravity of the drawer 20 itself needs to be overcome, that is, some force needs to be applied to open the drawer 20, so that the probability of the drawer 20 being opened by mistake is reduced, for example, the possibility of the drawer 20 being opened by children or pets is reduced.

[0074] In some specific embodiments of the utility model, in the second direction, the distance between the second lower extension section 3132 and the second upper extension section 3122 is greater than the diameter of the first pulley 32, so that when the first pulley 32 moves to between the second lower extension section 3132 and the second upper extension section 3122, the smoothness of the first pulley 32 when moving between the second lower extension section 3132 and the second upper extension section 3122 is ensured, the possibility that the first pulley 32 feels stuck when moving between the second lower extension section 3132 and the second upper extension section 3122 is reduced, and then the operation experience of a user when pulling and pushing the small drawer 20 is improved.

[0075] In some examples, the second upper extension section 3122 accounts for two-thirds of the length of the first upper groove wall 312 in the first direction, and the second lower extension section 3132 accounts for two-thirds of the length of the first lower groove wall 313 in the first direction, so that most of the path of the first pulley 32 when moving in the first sliding groove 31 is smooth.

[0076] In some embodiments, the distance between the first upper extension segment 3121 and the first lower extension segment 3131 is equal to the diameter of the first pulley 32, and the distance between the third upper extension segment 3123 and the third lower extension segment 3133 is equal to the diameter of the first pulley 32, so as to reduce the amplitude of the first pulley 32 and the drawer 20 when the first pulley 32 slides between the first upper extension segment 3121 and the first lower extension segment 3131 and between the third upper extension segment 3123 and the third lower extension segment 3133.

[0077] In some examples, the first direction extends along the front-rear direction, the second direction extends along the up-down direction, the side opening is an opening on the front side of the receiving cavity 11, the first upper extension segment 3121 is located on the front side of the second upper extension segment 3122, the first lower extension segment 3131 is located on the front side of the second lower extension segment 3132, and the first upper extension segment 3121 and the first lower extension segment 3131 are directly opposite along the up-down direction.

[0078] When the first pulley 32 moves to between the first upper extension segment 3121 and the first lower extension segment 3131, most of the drawer 20 is moved out of the receiving cavity 11, and at this time, the center of gravity of the drawer 20 is located on the front side of the side opening, so that the first upper extension segment 3121 and the first lower extension segment 3131 extend along the first direction, and the distance between the first upper extension segment 3121 and the first lower extension segment 3131 is equal to the diameter of the first pulley 32, so that the first upper extension segment 3121 and the first lower extension segment 3131 can be in contact with and apply force to the first pulley 32 to limit the position of the first pulley 32 and reduce the possibility of the first pulley 32 and the drawer 20 shaking.

[0079] In some embodiments, as shown in Figure 2 The first upper groove wall 312 further has a guide portion 3124, which is located closer to the side opening than the first to third upper extension segments 3123, and gradually extends downward from outside the receiving cavity 11 to inside the receiving cavity 11 along the first direction, so that when the first pulley 32 is installed in the first sliding groove 31 and the drawer 20 is placed in the receiving cavity 11, the first pulley 32 can easily enter the first sliding groove 31 through the guide portion 3124, reducing the difficulty of assembly and improving the efficiency of assembly.

[0080] In some embodiments, as shown in Figure 2 The first direction extends along the front-rear direction, the side opening is an opening on the front side of the receiving cavity 11, the guide portion 3124 is directly opposite to part of the first lower extension segment 3131 along the up-down direction, the first pulley 32 enters the first sliding groove 31 from the guide portion 3124, and the guide portion 3124 extends rearward and downward, so that the front opening of the first sliding groove 31 is larger, thereby facilitating the first pulley 32 to enter the first sliding groove 31.

[0081] In some embodiments of the utility model, as shown in Figure 2 、 Figure 3 The first connecting groove wall 314 is connected between the first upper groove wall 312 and the first lower groove wall 313, and extends obliquely in the second direction away from the first pulley 32, so that when the first pulley 32 moves in the first sliding groove 31, the contact area between the first pulley 32 and the first connecting groove wall 314 can be reduced, which on the one hand facilitates reducing the friction between the first pulley 32 and the first connecting groove wall 314, thereby improving the smoothness of the first pulley 32 when moving in the first sliding groove 31, and on the other hand can reduce the wear between the first pulley 32 and the first connecting groove wall 314.

[0082] In some embodiments, the first direction extends in the front-rear direction, the second direction extends in the up-down direction, the first sliding groove 31 defines a slot on one side in the left-right direction, and the first connecting groove wall 314 is a side wall on the other side of the first sliding groove 31 in the left-right direction.

[0083] In the left-right direction, the first connecting groove wall 314 extends obliquely upward or downward away from the first pulley 32 to reduce the contact area between the first connecting groove wall 314 and the first pulley 32, thereby reducing the resistance of the first pulley 32 when moving in the first sliding groove 31.

[0084] In some embodiments, the angle between the extension direction of the first connecting groove wall 314 and the second direction is 1°-60°.

[0085] The angle θ between the extension direction of the first connecting groove wall 314 and the second direction is greater than or equal to 1°, so that there is a gap between at least part of the first connecting groove wall 314 and the first pulley 32, thereby reducing the resistance of the first pulley 32 when moving in the first sliding groove 31.

[0086] The angle θ between the extension direction of the first connecting groove wall 314 and the second direction is less than or equal to 60°, so as to avoid that the first sliding groove 31 occupies too much space in the left-right direction. Specifically, the size of the first pulley 32 in the second direction is constant, the greater the angle θ between the extension direction of the first connecting groove wall 314 and the second direction, the larger the area occupied by the projection of the first connecting groove wall 314 in the second direction, and the larger the space occupied by the first sliding groove 31 in the left-right direction.

[0087] Specifically, the angle θ between the extension direction of the first connecting groove wall 314 and the second direction can be 1°, 3°, 5°, 10°, 15°, 20° or 25°, etc., which is not limited here

[0088] In some optional embodiments of the utility model, as shown in Figure 4 、 Figure 7 As shown, the drawer 20 is provided with a damping member 51, the damping member 51 is arranged along the first direction with the first pulley 32, and is in sliding cooperation with the first slide rail, so that when the user pulls the drawer 20 along the first direction, the drawer 20 can be slowly moved along the first direction, having the advantages of reducing noise, prolonging the service life of the drawer 20, improving safety and the like.

[0089] Specifically, reducing noise is an important reason for setting the damping member 51. When the drawer 20 is closed, if there is no damping member 51, due to the action of gravity, the drawer 20 can generate a strong impact force, resulting in noise. And the damping member 51 can slow down the impact force when the drawer 20 is closed, thereby reducing noise.

[0090] Secondly, prolonging the service life is one of the purposes of setting the damping member 51. If there is no damping member 51 during the closing process of the drawer 20, a strong impact force can be generated, causing the first slide rail and the second slide rail to be worn. Long-term use can affect the service life of the base assembly 1. And the damping member 51 can slow down the impact force when the drawer 20 is closed, protect the drawer 20 and the first slide rail and the second slide rail, and prolong the service life.

[0091] In addition, improving safety is another important reason for setting the damping member 51. The drawer 20 with the damping member 51 has a lighter collision sound when closing due to its own buffering, especially in a quiet environment such as a bedroom, which can effectively prevent noise from disturbing family members.

[0092] Moreover, the drawer 20 with the damping member 51 can prevent hand clamping, improving the safety of use.

[0093] In some specific embodiments of the utility model, the damping member 51 is an elastic material piece, so that the damping member 51 can absorb the impact force between the drawer 20 and the base 10, reduce the collision force between the drawer 20 and the base 10, and further facilitate noise reduction.

[0094] In some embodiments, the main material of the damping member 51 is polyurethane (PU), thermoplastic polyurethane elastomer (TPU), ethylene-propylene-diene rubber (EPDM), silicone, ethylene-vinyl acetate copolymer (EVA), thermoplastic elastomer (TPE) or polypropylene plastic foaming material (EPP).

[0095] In some embodiments, the Shore hardness of the damping member 51 is 10-100, and by adjusting the hardness of the damping piece, the resistance can be adjusted, and the hand feeling can be increased.

[0096] In some embodiments, the interference amount of the damping piece 51 with the first slide rail is 0-10mm, by adjusting the interference amount of the damping piece, the resistance can be adjusted, and the hand feeling is increased.

[0097] In some embodiments of the present application, the second slide rail is arranged on the drawer 20, the wheel shaft of the second pulley 42 is arranged on the base 10, and the second pulley 42 is arranged close to the side opening. In this way, when the drawer 20 is pushed or pulled in the first direction, the second pulley 42 can always be located in the second slide rail to support the position of the drawer 20 by using the second pulley 42.

[0098] Specifically, if the second pulley 42 is arranged away from the side opening, when the drawer 20 is pulled out in the first direction, the second pulley 42 is easy to disengage from the second slide rail, thereby affecting the stability of the cooperation between the drawer 20 and the base 10. By arranging the second pulley 42 close to the side opening, whether the drawer 20 is closed or pulled out, the second pulley 42 is always located in the second slide rail.

[0099] In some embodiments, the second pulley 42 is rotatably arranged on the base 10, and when the drawer 20 is pulled out, the second pulley 42 can roll in the second slide rail. When the second pulley 42 cannot roll due to the force of the wall body of the second slide rail, the second pulley 42 can slide in the second slide rail.

[0100] In some optional embodiments of the present application, as shown in Figure 8 , the second slide rail has a stop portion 52 at one end in the first direction, which is used to limit the disengagement of the drawer 20 from the base 10, thereby avoiding the drawer 20 from being pulled out of the accommodating cavity 11.

[0101] In some specific embodiments of the present application, as shown in Figure 2 , Figure 8 , the first slide rail is arranged on the base 10, the wheel shaft of the first pulley 32 is arranged on the drawer 20, and the drawer 20 is provided with a damping piece 51 in sliding cooperation with the first slide rail.

[0102] In some embodiments, as shown in Figure 8 , in the first direction, the stop portion 52 is located between the damping piece 51 and the second pulley 42. In this way, when the drawer 20 is pulled out in the first direction, the second pulley 42 moves in the second slide rail to the position where it is stopped by the damping piece 51, which can avoid the damping piece 51 from leaking out of the accommodating cavity 11, thereby facilitating the protection of the damping piece 51 and improving the overall aesthetics of the base assembly 1.

[0103] In some embodiments, as shown in Figure 8As shown, the stop portion 52 is located between the first pulley 32 and the second pulley 42 in the first direction, so that when the second pulley 42 moves to the position of stopping the damping member 51 in the second slide rail when the drawer 20 is pulled out in the first direction, the first pulley 32 can be prevented from being exposed outside the accommodating cavity 11, thereby protecting the first pulley 32 and improving the overall aesthetics of the base assembly 1.

[0104] In some optional embodiments of the present application, as shown in Figure 5 、 Figure 6 As shown, the two side walls of the drawer 20 are provided with second slide rails in the third direction, and the first direction, the second direction and the third direction are perpendicular to each other, so as to support the movement of the drawer 20 in the first direction from both sides of the drawer 20 in the third direction, improve the stability of the drawer 20 when moving in the first direction, and at the same time limit the position of the drawer 20 in the third direction, thereby reducing the amplitude of the drawer 20 in the third direction.

[0105] Each second slide rail defines a second sliding groove 41 with the notch downward, and the gap between the groove side wall of at least one second sliding groove 41 and the corresponding second pulley 42 is adapted to the installation error of the drawer 20 and the base 10 in the third direction.

[0106] Specifically, when the two second pulleys 42 enter the second slide rails, the size of at least one second sliding groove 41 in the third direction is greater than that of the corresponding second pulley 42 in the third direction, so as to release the tolerance of the drawer 20 and the base 10 in the third direction.

[0107] In addition, the notch of the second sliding groove 41 is downward, so that when the drawer 20 is installed into the accommodating cavity 11, the second pulley 42 is conveniently entered into the second sliding groove 41, thereby conveniently supporting the drawer 20 on the second pulley 42 and reducing the installation difficulty.

[0108] In some embodiments, as shown in Figure 5 、 Figure 6 The third direction extends in the left-right direction, and the size of at least one second sliding groove 41 in the third direction is greater than that of the second pulley 42 in the third direction, so as to release the tolerance of the drawer 20 and the base 10 in the left-right direction.

[0109] When the drawer 20 is pulled in the first direction, the second pulley 42 and the at least one side wall of the second sliding groove 41 in the left-right direction are in sliding fit, so as to limit the position of the drawer 20 in the third direction, thereby reducing the amplitude of the drawer 20 in the third direction.

[0110] In some embodiments, as shown in Figure 5 、 Figure 6As shown, drawer 20 defines a storage cavity with an upward-facing opening, allowing the user to place items into the storage cavity from the opening. The opening of drawer 20 is provided with a flange 21, which can cover the gap between drawer 20 and the wall of the storage cavity 11 when drawer 20 is pulled out, thereby preventing the components between drawer 20 and the wall of storage cavity 11 from being observed from above drawer 20, thus improving the aesthetics of base assembly 1.

[0111] The second slide rail is located below the flange 21, which extends along the first direction. When the drawer 20 is pulled out, the flange 21 can cover the second slide rail from above to hide it and improve the aesthetics of the base assembly 1.

[0112] In some specific embodiments of this utility model, such as Figure 2 , Figure 8 As shown, the first slide rail is located on the base 10, and the axle of the first pulley 32 is located on the drawer 20. The first slide rail has a first upper groove wall 312 and a first lower groove wall 313. The first pulley 32 is supported on the first lower groove wall 313, so as to limit the position of the first pulley 32 in the vertical direction by using the first upper groove wall 312 and the first lower groove wall 313, thereby reducing the amplitude of the drawer 20 wobbling in the vertical direction.

[0113] The second slide rail is located on the drawer 20, and the axle of the second pulley 42 is located on the base 10. The second slide rail has a second left groove wall and a second right groove wall. The second pulley 42 is located on the second left groove wall and the second right groove wall, so as to limit the position of the second pulley 42 in the left and right directions by using the second left groove wall and the second right groove wall, thereby reducing the amplitude of the drawer 20 wobbling in the left and right directions (it should be understood here that the above directional limitation is only for the convenience of describing the attached drawings and does not limit the actual setting position and direction of the base assembly 1).

[0114] The second slide rail is located below the first pulley 32, and the second pulley 42 is located below the first slide rail.

[0115] In some embodiments, the second slide rail has a downward groove and the top of the second slide rail is an arc surface to adapt to the shape of the second pulley 42, thereby limiting the position of the second pulley 42 in the left and right directions while ensuring that the second pulley 42 can move smoothly within the second slide rail.

[0116] In some embodiments, the base 10 is provided with a first sliding rail and a second sliding pulley 42, which are located on the same side of the base 10 in the left-right direction or different sides of the base 10 in the left-right direction, and correspondingly, the drawer 20 is provided with a second sliding rail and a first sliding pulley 32, which are located on the same side of the drawer 20 in the left-right direction or different sides of the drawer 20 in the left-right direction.

[0117] In some examples, the drawer 20 is provided with a damping member 51, which is in sliding cooperation with the first sliding rail.

[0118] In other embodiments, the base 10 is provided with two first sliding rails and two second sliding pulleys 42, and each side of the base 10 in the left-right direction is provided with a first sliding rail and a second sliding pulley 42, and correspondingly, the drawer 20 is provided with two second sliding rails and two first sliding pulleys 32, and each side of the drawer 20 in the left-right direction is provided with a second sliding rail and a first sliding pulley 32.

[0119] In some examples, the drawer 20 is provided with two damping members 51, each of which is in sliding cooperation with the first sliding rail.

[0120] In some embodiments of the present application, at least one wall of the accommodating cavity 11 is provided with a reinforcing rib, which defines a regular hexagonal cavity to enhance the structural strength of the base 10.
