[0049] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0050] The following describes the embodiments of the present utility model in conjunction with Figures 1 to 5 , the embodiments of the present utility model are described.

[0051] According to an embodiment of the present utility model, a storage box is provided, which includes a box body 1, a lifting mechanism 2, and a reset mechanism 3. Among them, the box body 1 is used to accommodate an article 100. The lifting mechanism 2 is arranged in the box body 1. The lifting mechanism 2 is driven to move to drive the accommodated article 100 to move in the height direction of the box body 1 and position the article 100 at a desired position. The reset mechanism 3 is in transmission connection with the lifting mechanism 2 and is used to drive the lifting mechanism 2 to reset.

[0052] For the storage box of the present application, as the thickness of the article 100 gradually decreases during use, at this time, the arranged lifting mechanism 2 is driven to move to drive the accommodated article 100 to move in the height direction of the box body 1, and position the article 100 at a desired position, so as to facilitate the user to take the article 100 in the box body 1 and ensure the stability during use. When the article 100 is used up / needs to be replaced, the arranged reset mechanism 3 drives the lifting mechanism 2 to reset, so that the lifting mechanism 2 resets to the initial position, which is convenient for the user's next use. There is no need for the user to manually reset the lifting mechanism 2, making it more convenient to use and providing a better user experience.

[0053] In some embodiments, the box body 1 is provided with a top cover, and an opening 13 is provided on the top cover for the user to take the article 100 placed inside the box body 1. The article 100 is, for example, a tissue, or it can be other articles.

[0054] Among them, the box body 1 can be set in any shape, such as square, circular, oval, irregular polygon, etc. For the convenience of description, the present application takes the storage box as a square box body 1 as an example for description, but the present application is not limited thereto.

[0055] In some embodiments, the reset mechanism 3 is arranged to drive the lifting mechanism 2 to reset under the action of an additional external force. In other embodiments, the reset mechanism 3 is arranged to drive the lifting mechanism 2 to reset by releasing an elastic force. For example, the elastic force is an elastic torsion force or an elastic tightening force. In an example, the reset mechanism 3 is arranged to drive the lifting mechanism 2 to reset by releasing an elastic tightening force.

[0056] Among them, the elastic tightening force can be provided by other mechanisms, or the elastic tightening force is provided by the lifting mechanism 2 to further simplify the structure and reduce costs. For example, when the lifting mechanism 2 drives the accommodated article 100 to move, it drives the reset mechanism 3 to elastically tighten to form an elastic tightening force. Then, the reset mechanism 3 drives the lifting mechanism 2 to reset by releasing the elastic tightening force. In the present application, when the lifting mechanism 2 drives the article 100 to move, it synchronously drives the reset mechanism 3 to elastically tighten, and there is no need to set an additional driving structure to elastically tighten the reset mechanism 3, which can simplify the structure and save the setting cost.

[0057] In some embodiments, the reset mechanism 3 includes a transmission component 31 and an elastic structure 32. Among them, the transmission component 31 is in transmission connection with both the lifting mechanism 2 and the elastic structure 32. When the lifting mechanism 2 drives the accommodated article 100 to move, the elastic structure 32 is elastically tightened by driving the transmission component 31. The elastic structure 32 drives the lifting mechanism 2 to reset by releasing the elastic tightening force through the transmission component 31.

[0058] The reset mechanism 3 is configured to include a transmission component 31 and an elastic structure 32. When the lifting mechanism 2 drives the article 100 to move, the elastic structure 32 is elastically tightened by driving the transmission component 31. When the lifting mechanism 2 needs to be reset, the elastic structure 32 releases the elastic tightening force to drive the transmission component 31 to act, and then drives the lifting mechanism 2 to reset.

[0059] In some embodiments, a first transmission mating portion 2112 is provided on the lifting mechanism 2, and a second transmission mating portion 3111 mating with the first transmission mating portion 2112 is provided on the transmission component 31. The first transmission mating portion 2112 and the second transmission mating portion 3111 are in concave-convex mating. The lifting mechanism 2 is driven to rotate to drive the article 100 to move in the height direction of the box body 1, and the lifting mechanism 2 drives the transmission component 31 to rotate through the concave-convex mating.

[0060] The transmission connection between the lifting mechanism 2 and the transmission component 31 is realized through the concave-convex mating of the first transmission mating portion 2112 and the second transmission mating portion 3111. When the lifting mechanism 2 is driven to rotate to drive the article 100 to move in the height direction of the box body 1, at the same time, the lifting mechanism 2 drives the transmission component 31 to rotate through the concave-convex mating, and the concave-convex mating realizes the reliable transmission of power.

[0061] In some embodiments, the transmission component 31 includes a first gear 311 and a second gear 312. Among them, the first gear 311 and the second gear 312 are meshed. A second transmission mating portion 3111 is provided on the first gear 311. The second gear 312 is in transmission connection with the elastic structure 32. The lifting mechanism 2 drives the first gear 311 to rotate through the concave-convex mating, and the first gear 311 drives the second gear 312 meshed with it to rotate to drive the elastic structure 32 to be elastically tightened. Different gear parameters can be set to change the rotation speed through gear meshing. For example, the first gear 311 is set as a large gear and the second gear 312 is set as a small gear. When the large gear drives the small gear to rotate, the rotation speed of the small gear is faster than that of the large gear to obtain the elastic tightening force faster.

[0062] In the above setting, when the article 100 needs to move along the height direction of the box body 1, the lifting mechanism 2 is driven to rotate to drive the article 100 to move in the height direction of the box body 1. At the same time, the lifting mechanism 2 drives the first gear 311 to rotate through the concave-convex cooperation, and then drives the second gear 312 meshing with the first gear 311 to rotate, thereby driving the elastic structure 32 to elastically contract.

[0063] Further, the elastic structure 32 drives the second gear 312 to rotate reversely by releasing the elastic contraction force. The second gear 312 drives the first gear 311 to rotate reversely, and the first gear 311 drives the lifting mechanism 2 to rotate reversely through the concave-convex cooperation so that the lifting mechanism 2 is reset.

[0064] In some embodiments, the elastic structure 32 includes a coil spring 321. The central end of the coil spring 321 is connected to the transmission assembly 31, so that when the lifting mechanism 2 drives the accommodated article 100 to move, the transmission assembly 31 drives the coil spring 321 to elastically contract along its center.

[0065] When the lifting mechanism 2 drives the accommodated article 100 to move, the transmission assembly 31 drives the coil spring 321 to elastically contract along its center. When the lifting mechanism 2 needs to be reset, the coil spring 321 releases the elastic contraction force to drive the transmission assembly 31 to rotate reversely, and then the lifting mechanism 2 rotates reversely to achieve reset.

[0066] When the transmission assembly 31 includes the first gear 311 and the second gear 312, the central end of the coil spring 321 is connected to the center of the second gear 312. When the second gear 312 rotates, it drives the central end of the coil spring 321 to wind together to elastically contract the coil spring 321.

[0067] In some embodiments, the elastic structure 32 further includes an outer cover 322. The outer cover 322 is disposed on the box body 1 and forms a cavity for accommodating the coil spring 321 between the outer cover 322 and the side wall of the box body 1. The outer end of the coil spring 321 is connected to the outer cover 322.

[0068] The outer cover 322 can protect the coil spring 321. At the same time, the outer end of the coil spring 321 is connected to the outer cover 322. When the second gear 312 rotates, it drives the central end of the coil spring 321 to elastically contract.

[0069] The shape of the outer cover 322 is not specifically limited. The area of the outer cover 322 is greater than or equal to the area of the coil spring 321 to completely cover the coil spring 321.

[0070] In some embodiments, the reset mechanism 3 includes a first limiting portion 113. The first limiting portion 113 is disposed on the box body 1 and is used to abut and cooperate with the reset mechanism 3 so that the reset mechanism 3 has an initial elastic tightening force at the initial position of the lifting mechanism 2. For example, in the case of including a structure of a coil spring 321, the presence of the first limiting portion 113 causes the coil spring 321 to be in an elastically tightened state at the initial position of the lifting mechanism 2, so that even if the moving stroke of the lifting mechanism 2 is very short, the coil spring 321 can still drive the reset mechanism 3 to reset.

[0071] For example, the first limiting portion 113 abuts and cooperates with the first gear 311 in the reset mechanism 3. When the lifting mechanism 2 is in the initial position, the first limiting portion 113 limits the starting position of the first gear 311, so that the coil spring 321 is still in an elastically tightened state at this starting position. On the one hand, it enables the lifting mechanism 2 to be reset to the initial position even if it moves a very short stroke. On the other hand, when the lifting mechanism 2 is reset, the first gear 311 cannot continue to rotate in the reverse direction under the limitation of the first limiting portion 113, so that the second gear 312 meshing with the first gear 311 also cannot continue to rotate in the reverse direction, and then the coil spring 321 is kept in a state with an initial elastic tightening force.

[0072] In some embodiments, the first limiting portion 113 is a first limiting groove disposed on the inner wall of the box body 1. The first limiting groove is arranged along the rotation track of the first gear 311. A limiting protrusion 3112 is arranged on the first gear 311, and the limiting protrusion 3112 abuts and cooperates in the first limiting groove, thereby realizing the limitation of the reset mechanism 3 by the first limiting portion 113.

[0073] In some embodiments, the reset mechanism 3 includes a second limiting portion 114. The second limiting portion 114 is disposed on the box body 1 and is used to limit the maximum displacement of the lifting mechanism 2, and further limit the maximum height of the article 100 moving and rising inside the box body 1, so as to avoid the collision between the article 100 and the top cover of the box body 1.

[0074] For example, the second limiting portion 114 abuts and cooperates with the transmission assembly 31 to limit the rotation of the transmission assembly 31, and further prevent the lifting mechanism 2 from continuing to rotate to realize its limitation.

[0075] In some embodiments, the second limiting portion 114 abuts and cooperates with the first gear 311 in the transmission assembly 31. When the lifting mechanism 2 drives the article 100 to move upward, it drives the first gear 311 to rotate. When the second limiting portion 114 abuts against the first gear 311, the lifting mechanism 2 moves to the maximum displacement and the first gear 311 cannot continue to rotate.

[0076] In some embodiments, the second limiting portion 114 is a second limiting groove arranged on the inner wall of the box body 1, and the second limiting groove is arranged along the rotation trajectory of the first gear 311. When the lifting mechanism 2 drives the first gear 311 to rotate, the first gear 311 drives the limiting protrusion 3112 to abut and cooperate with the second limiting groove, thereby realizing the limiting of the reset mechanism 3 by the second limiting portion 114, thereby limiting the maximum displacement of the lifting mechanism 2.

[0077] The second limiting portion 114 and the first limiting portion 113 are respectively arranged on both sides of the first gear 311 to limit the two sides of the first gear 311 respectively, so that the first gear 311 can rotate within the range between the second limiting portion 114 and the first limiting portion 113 to drive the coil spring 321 to elastically tighten or drive the lifting mechanism 2 to reset.

[0078] In some embodiments, the lifting mechanism 2 includes a lifter 21 and at least two lifting members 22, wherein the lifter 21 is arranged on the first side wall 11 of the box body 1, the reset mechanism 3 is transmission-connected to the lifter 21, at least two lifting members 22 are accommodated in the box body 1, the first ends of the at least two lifting members 22 are respectively positioned at the first position and the second position of the second side wall 12 of the box body 1, and the second ends of the at least two lifting members 22 are connected to the lifter 21, wherein the first side wall 11 is opposite to the second side wall 12, and the lifter 21 is used to drive the second end of the lifting member 22 to move so that the lifting member 22 moves in the height direction of the box body 1.

[0079] With the above arrangement, the thickness of the article 100 gradually decreases as it is used. At this time, the lifter 21 and the lifting member 22 arranged on the storage box drive the article 100 to rise along the height direction of the box body 1, so that the user can take the article 100 in the box conveniently. The lifter 21 is arranged to simultaneously drive the second ends of at least two lifting members 22 to move, and the user does not need to operate multiple lifting members 22 separately, which is more convenient to use and provides a better user experience.

[0080] In some embodiments, the box body 1 is a square box body 1, and the first side wall 11 and the second side wall 12 arranged opposite to each other are both rectangular. In other embodiments, the box body 1 is set to other shapes, such as circular, elliptical, irregular polygonal, etc. When the box body 1 is set to a circular or elliptical shape, there is no obvious boundary between the first side wall 11 and the second side wall 12 arranged opposite to each other thereon. When the box body 1 is set to an irregular polygon, the side walls arranged opposite to each other thereon can have a variety of combinations. Therefore, the first side wall 11 and the second side wall 12 are not limited to the positions shown in this embodiment, as long as the lifter 21 arranged on the first side wall 11 can drive the lifting member 22 whose first end is positioned on the second side wall 12 to move in the height direction of the box body 1 through the second end of the lifting member 22.

[0081] In some embodiments, the lifting member 22 is provided as a rope. In other embodiments, the lifting member 22 is provided as an elastic band. In still other embodiments, the lifting member 22 is provided as a wire. Alternatively, the lifting member 22 may also be provided as other article 100 that can achieve a function similar to that of a rope, which will not be elaborated herein. For convenience of description, this application describes the case where the lifting member 22 is a rope as an example, but this application is not limited thereto.

[0082] In addition, at least two lifting members 22 are accommodated in the box body 1. In some embodiments, the lifting member 22 is provided as two, so that the article 100 is stably placed on the lifting member 22. In other embodiments, the lifting member 22 is provided as multiple, so as to improve the supporting effect on the article 100. In the case where multiple lifting members 22 are provided, the multiple lifting members 22 can be divided into two groups, and the two groups of lifting members 22 respectively correspond to the setting mode of two lifting members 22. Alternatively, in the case where the lifting member 22 is multiple, positioning positions corresponding to the first ends of the multiple lifting members 22 are provided on the second side wall 12, and the second ends of the multiple lifting members 22 are all connected to the lifter 21. For convenience of description, this application describes the case where the lifting member 22 is two as an example, but this application is not limited thereto.

[0083] The first ends of the two lifting members 22 are respectively positioned at the first position and the second position on the second side wall 12 of the box body 1. In some embodiments, the first end of the lifting member 22 may be fixedly connected to the second side wall 12 of the box body 1. For example, the first end of the lifting member 22 is fixedly bonded to the second side wall 12 of the box body 1. In other embodiments, the first end of the lifting member 22 may be movably connected to the second side wall 12 of the box body 1. For example, holes are provided on the box body 1, and the first end of the lifting member 22 passes through the holes and is movably connected to the box body 1. In one example, through holes are provided at both the first position and the second position, and the first ends of the two lifting members 22 respectively pass through the corresponding through holes provided on the box body 1 and are independently connected to the box body 1. In another example, second through holes 121 are provided at both the first position and the second position, and the first ends of the two lifting members 22 respectively pass through the second through holes 121 and are connected to each other. Among them, in the case where the two lifting members 22 are connected to each other, the first ends of the two lifting members 22 may be connected by a connecting member or by tying a knot. Alternatively, the two lifting members 22 are formed by a single rope. Specifically, one end of a single rope successively passes through the second through holes 121 provided at the first position and the second position and is connected to the lifter 21, and the other end of the rope is also connected to the lifter 21, thereby achieving the purpose of forming two lifting members 22 by a single rope to reduce the manufacturing cost.

[0084] In some embodiments, a third through-hole 112 corresponding to the second through-hole 121 is provided on the first sidewall 11. The second ends of at least two lifting members 22 respectively pass through the corresponding third through-holes 112 and are connected to the lifter 21, so as to facilitate the installation connection between the lifting members 22 and the lifter 21.

[0085] In practical applications, in order to improve the stability of the article 100 during movement, in one embodiment, at least two lifting members 22 are arranged in a crosswise manner within the box body 1.

[0086] By arranging the lifting members 22 in a crosswise manner, the lifting members 22 can form a support surface at the bottom surface of the box body 1 in a crosswise manner, so as to achieve stable support for the article 100 thereon.

[0087] Furthermore, the crosswise positions of at least two lifting members 22 are fixedly connected to form a cross point 221. In some embodiments, the crosswise positions of the two lifting members 22 are fixed by bonding. In other embodiments, the crosswise positions are fixed by fixing members. For example, a buckle is provided at the crosswise position to snap the two lifting members 22 together.

[0088] Through the above arrangement, the crosswise positions of the lifting members 22 can be fixed to form a stable cross point 221, enhancing the stable support for the article 100 thereon.

[0089] In this embodiment, only one cross point 221 is formed after the two lifting members 22 cross within the box body 1. In other embodiments, multiple lifting members 22 may form multiple cross points 221, which is not limited to this embodiment.

[0090] In practical applications, since the cross point 221 will move towards the first sidewall 11 of the box body 1 as the lifting members 22 rise, in order to enable the article 100 to move fully within the box body 1 and avoid the situation where the cross point 221 contacts the sidewall and affects the movement of the article 100, the initial position of the cross point 221 is set such that when the lifting members 22 rise to the middle height of the box body 1, the cross point 221 is located at the center position of the bottom surface of the box body 1.

[0091] Through the above arrangement, it can be ensured that the lifting members 22 can rise to the highest height of the box body 1, and thus the article 100 thereon can be conveyed to the highest position of the box body 1, and the cross point 221 is always within the range of the bottom surface of the box body 1, avoiding the situation where the lifting members 22 cannot rise due to the cross point 221 moving to the sidewall of the box body 1.

[0092] In some embodiments, the lifter 21 is used to drive the second end of the lifting member 22 to move, so that the lifting member 22 moves in the height direction of the box body 1. In some embodiments, the lifter 21 is arranged to move relative to the first side wall 11, that is, by pulling / pushing the lifter 21 to drive at least two lifting members 22 to move in the height direction of the box body 1. In other embodiments, the lifter 21 is arranged to rotate relative to the first side wall 11 to drive at least two lifting members 22 to move in the height direction of the box body 1. In the present application, the lifter 21 drives at least two lifting members 22 to move in the height direction of the box body 1 in a rotational manner, making the operation fast and saving operation space.

[0093] In some embodiments, when the lifter 21 rotates relative to the first side wall 11, the lifting member 22 is wound around the lifter 21, thereby driving the lifting member 22 to move in the height direction of the box body 1, so as to simultaneously store the lifting member 22 during the lifting process, saving operation space and making the storage box more concise.

[0094] For example, the lifter 21 includes a rotating shaft 212 and a winding portion 213 provided on the rotating shaft 212. Among them, the rotating shaft 212 is rotatably connected to the first side wall 11, and the winding portion 213 is sleeved on the outer periphery of the rotating shaft 212. When the rotating shaft 212 rotates relative to the first side wall 11, the lifting member 22 is driven to be wound around the winding portion 213. For example, the winding portion 213 is arranged in a cylindrical shape and is fixedly sleeved on the outer wall of the rotating shaft 212 located on the first side wall 11 of the box body 1.

[0095] In one example, the second ends of the two lifting members 22 are both connected to the winding portion 213. When the rotating shaft 212 is rotated to rotate relative to the first side wall 11, the rotating shaft 212 drives the lifting member 22 to be wound around the winding portion 213, thereby realizing the winding and storage of the lifting member 22.

[0096] In another example, two connection holes 2131 for the lifting member 22 to pass through are provided on the side wall of the winding portion 213, and the second ends of the two lifting members 22 respectively pass through the two connection holes 2131 and are connected to each other. Or in the case where a rope is used as the lifting member 22 as described above, as Figure 2 shown, the starting end of the rope can be placed at the intersection point 221, and the other end of the rope passes through the two second through holes 121 on the second side wall 12 from the inside of the storage box towards the second side wall 12 and then enters the storage box. After crossing the starting end of the rope in the storage box, it passes through the through hole on the first side wall 11, the two connection holes 2131 on the winding portion 213 and another through hole on the first side wall 11 in sequence towards the first side wall 11, and finally converges with the starting end at the intersection point 221 to form a lifting path (as Figure 2 shown by the arrow in).

[0097] In practical applications, for the convenience of operating the lifter 21, in some embodiments, the first side wall 11 is provided with a first through hole 111. The lifter 21 further includes a knob 211, and the knob 211 is connected to the winding portion 213. The rotating shaft 212 passes through the first through hole 111 to rotatably mount the lifter 21 on the first side wall 11.

[0098] The first through hole 111 facilitates the rotational connection of the rotating shaft 212 to the first side wall 11, thereby realizing the rotational mounting of the lifter 21 on the box body 1. The knob 211 facilitates the user to operate the lifter 21. The user drives the winding portion 213 and the rotating shaft 212 to rotate by rotating the knob 211, and then winds the lifting member 22 onto the winding portion 213.

[0099] In some embodiments, the lifter 21 includes a shielding portion 216. The shielding portion 216 is disposed on the box body 1 and is used to shield the lifting member 22 wound on the lifter 21, so as to improve the aesthetics of the entire storage box.

[0100] It can be understood that there is a winding space between the shielding portion 216 and the winding portion 213, and the winding space is used to accommodate the lifting member 22 wound on the winding portion 213. For example, the shielding portion 216 can be set as a cylindrical structure, and the winding portion 213 is disposed in the hollow of the cylindrical structure, so as to shield the winding portion 213 and the lifting member 22 wound thereon through the cylindrical structure.

[0101] In some embodiments, the shielding portion 216 is provided with an avoidance hole 2161 for the lifting member 22 to pass through. The second end of the lifting member 22 passes through the avoidance hole 2161 and is connected to the lifter 21. The setting of the avoidance hole 2161 facilitates the connection between the lifting member 22 and the lifter 21, and avoids the setting of the shielding portion 216 from interfering with the connection between the lifting member 22 and the lifter 21.

[0102] Correspondingly, there are also two avoidance holes 2161, and the two avoidance holes 2161 are arranged in one-to-one correspondence with the two connection holes 2131 on the winding portion 213.

[0103] In practical applications, when the lifting member 22 is lifted to the required position, it needs to be maintained at that position. In some embodiments, the storage box further includes an anti-backward mechanism. The anti-backward mechanism is used to position the position of the lifter 21 after the force applied to the lifter 21 is removed, so that the article 100 is positioned at the required position, and is used to release the locked state of the anti-backward mechanism when driven, so that the reset mechanism 3 drives the lifting mechanism 2 to reset.

[0104] In this application, the anti-backward mechanism is in a locked state when positioning the position of the lifter 21. At this time, the reset mechanism 3 cannot drive the lifting mechanism 2 to move. When the anti-backward mechanism is driven to release the locked state, at this time, the reset mechanism 3 can drive the lifting mechanism 2 to move and reset, ensuring the reliability of the entire structure.

[0105] In some embodiments, the lifter 21 is rotatably connected to the first side wall 11. The anti-back-off mechanism includes a first concave-convex structure 2111 provided on the lifter 21 and a second concave-convex structure 2162 provided on the first side wall 11 and cooperating with the first concave-convex structure 2111. After the force applied to the lifter 21 is removed, the first concave-convex structure 2111 and the second concave-convex structure 2162 are engaged with each other to prevent the lifting member 22 from backing off and thus position the lifter 21.

[0106] During use, after the lifting member 22 is moved to the corresponding position by the lifter 21, the force applied to the lifter 21 is removed. The first concave-convex structure 2111 and the second concave-convex structure 2162 are engaged with each other to prevent the lifting member 22 from backing off and thus position the lifter 21, ensuring the stability of the article 100 during use within the box body 1.

[0107] In some embodiments, the first concave-convex structure 2111 and the second concave-convex structure 2162 are serrated. The force applied to the lifter 21 drives the first concave-convex structure 2111 to overcome the frictional force with the second concave-convex structure 2162 so that the lifter 21 rotates relative to the first side wall 11. After the force applied to the lifter 21 is removed, the first concave-convex structure 2111 and the second concave-convex structure 2162 are engaged with each other to prevent the lifter 21 from rotating back and thus position the lifter 21.

[0108] In the present application, the first concave-convex structure 2111 and the second concave-convex structure 2162 are set to be serrated. The force applied to the lifter 21 drives the first concave-convex structure 2111 to rotate relative to the second concave-convex structure 2162 while overcoming the frictional force therebetween, thereby realizing the damped rotation of the lifter 21 relative to the first side wall 11 to drive the lifting member 22 to move in the height direction of the box body 1. After the force applied to the lifter 21 is removed, the frictional force between the first concave-convex structure 2111 and the second concave-convex structure 2162 causes the first concave-convex structure 2111 and the second concave-convex structure 2162 to be engaged with each other to prevent the lifter 21 from rotating back and thus position the lifter 21.

[0109] In some embodiments, when the lifter 21 includes a winding portion 213, the first concave-convex structure 2111 is provided on the end surface of the winding portion 213 facing the first side wall 11, and the second concave-convex structure 2162 is provided on the end surface of the first side wall 11 facing the winding portion 213. Rotating the knob 211 drives the winding portion 213 to rotate, and further drives the first concave-convex structure 2111 on the winding portion 213 to rotate relative to the second concave-convex structure 2162 on the first side wall 11, so as to realize the rotational movement of the lifter 21.

[0110] In some embodiments, when the lifter 21 includes a knob 211 and a shielding portion 216, the shielding portion 216 is disposed on the first side wall 11, the winding portion 213 is disposed within the shielding portion 216, the first concavo-convex structure 2111 is disposed on the end surface of the knob 211 facing the shielding portion 216, and the second concavo-convex structure 2162 is disposed on the end surface of the shielding portion 216 facing the knob 211. When the knob 211 is not subject to an external force, it is engaged with the shielding portion 216, thereby completely shielding the internal winding portion 213 to ensure overall aesthetics. When the knob 211 is rotated relative to the shielding portion 216, the knob 211 drives the first concavo-convex structure 2111 thereon to rotate relative to the second concavo-convex structure 2162 on the shielding portion 216 to achieve the rotational movement of the lifter 21.

[0111] It should be noted that the first concavo-convex structure 2111 and the second concavo-convex structure 2162 can be set to be entirely matched or partially matched. That is, the first concavo-convex structure 2111 is arranged in an annular serrated structure on the end surface, and the second concavo-convex structure 2162 is also arranged in an annular serrated structure so that the two are entirely matched to increase the frictional force. Alternatively, one of the first concavo-convex structure 2111 or the second concavo-convex structure 2162 is arranged in an annular serrated structure, and the other is arranged in a partial serrated structure so that the first concavo-convex structure 2111 and the second concavo-convex structure 2162 are partially matched to reduce the manufacturing cost.

[0112] In some embodiments, the anti-backward mechanism is used to separate the mutually engaged first concavo-convex structure 2111 and the second concavo-convex structure 2162 when driven, so that the reset mechanism 3 drives the lifting mechanism 2 to reset.

[0113] When the lifter 21 includes a rotating shaft 212 and a knob 211, the anti-backward mechanism includes an elastic member 215. A third limiting portion 214 is provided at one end of the rotating shaft 212 away from the knob 211, and the elastic member 215 is disposed between the third limiting portion 214 and the first side wall 11. Among them, the third limiting portion 214 is used to limit the position between the rotating shaft 212 and the first side wall 11. The elastic member 215 is placed between the third limiting portion 214 and the first side wall 11. Through the elastic deformation force of the elastic member 215, the cooperation between the knob 211 and the first side wall 11 of the box body 1 is made closer, and the engagement between the first concavo-convex structure 2111 and the second concavo-convex structure 2162 is also made closer, thereby enhancing the positioning effect on the lifter 21. In addition, the elastic member 215 can also provide a certain movement stroke for the knob 211, so that the first transmission mating portion 2112 and the second transmission mating portion 3111, the first concavo-convex structure 2111 and the second concavo-convex structure 2162 can be separated, thereby releasing the locked state of the anti-backward mechanism.

[0114] In one example, the elastic member 215 is arranged as a spring. For example, the spring is sleeved on the outer periphery of the rotating shaft 212. One end of the spring abuts against the limiting portion, and the other end abuts against the first side wall 11.

[0115] When using the lifting mechanism to drive the accommodated article 100 to move in the height direction of the box body 1, the knob 211 can be directly rotated, and the external force is used to overcome the friction force between the first concave-convex structure 2111 and the second concave-convex structure 2162 to drive the lifting member to rise. Or, the knob 211 is pulled out a small distance in the direction away from the box body 1. At this time, the elastic member 215 is compressed and deformed, the first concave-convex structure 2111 on the knob 211 disengages from the second concave-convex structure 2162, and the two are disengaged. And the first transmission engaging portion 2112 and the second transmission engaging portion 3111 are still in the concave-convex engagement state. The knob 211 is rotated to drive the lifting member 22 to be wound around the winding portion 213, making the lifting process more labor-saving. It should be noted that in order to ensure that the first transmission engaging portion 2112 and the second transmission engaging portion 3111 are still in the engaged state when the first concave-convex structure 2111 is disengaged from the second concave-convex structure 2162, the engagement depth of the first concave-convex structure 2111 and the second concave-convex structure 2162 is set to be less than the engagement depth of the first transmission engaging portion 2112 and the second transmission engaging portion 3111.

[0116] When it rises to the specified position, the force applied to the knob 211 is removed, and the deformation force of the elastic member 215 drives the knob 211 to fit against the first side wall 11 of the box body 1, so that the first concave-convex structure 2111 is tightly engaged with the second concave-convex structure 2162, and the two are snap-fixed to achieve the positioning of the lifter 21.

[0117] When the lifting mechanism needs to be reset, the knob 211 is pulled out a large distance in the direction away from the box body 1. At this time, the elastic member 215 is compressed and deformed, the first concave-convex structure 2111 on the knob 211 disengages from the second concave-convex structure 2162, and the two are disengaged. And the first transmission engaging portion 2112 is disengaged from the second transmission engaging portion 3111. The reset mechanism 3 drives the lifting mechanism 2 to reset. The force applied to the knob 211 is removed, and the deformation force of the elastic member 215 drives the knob 211 to fit against the first side wall 11 of the box body 1, so that the first concave-convex structure 2111 is tightly engaged with the second concave-convex structure 2162, and the first transmission engaging portion 2112 and the second transmission engaging portion 3111 are engaged.

[0118] In some embodiments, the third limiting portion 214 is arranged as an end cap. The end cap is connected to the other end of the rotating shaft 212 away from the knob 211 to snap the lifter 21 on the first side wall 11 to ensure the structural reliability of the connection between the lifter 21 and the box body 1.

[0119] Specifically, the end cap is circular and its diameter is larger than the aperture of the first through hole 111, so that the end cap cannot pass through the first through hole 111 and thus the rotating shaft 212 is limited in the first through hole 111.

[0120] In some embodiments, the knob 211 is provided with a first transmission engaging portion 2112 and a first concave-convex structure 2111 that cooperates with the second concave-convex structure 2162. The reset mechanism 3 includes a transmission assembly 31. The transmission assembly 31 is provided with a second transmission engaging portion 3111 that engages with the first transmission engaging portion 2112 in a concave-convex manner. When the elastic member 215 is compressed under the action of the force applied to the lifter 21, the first concave-convex structure 2111 is separated from the second concave-convex structure 2162 and the first transmission engaging portion 2112 is separated from the second transmission engaging portion 3111. The reset mechanism 3 drives the lifting mechanism 2 to reset. After the force applied to the lifter 21 is removed, the elastic member 215 drives the knob 211 to reset.

[0121] Hereinafter, a description will be given by taking the reset mechanism 3 including a transmission assembly 31 and an elastic structure 32, where the transmission assembly 31 includes a first gear 311 and a second gear 312, and the elastic structure 32 includes a winding spring 321 as an example.

[0122] Among them, the lifter 21 includes a knob 211, a rotating shaft 212, a winding portion 213, a third limiting portion 214, an elastic member 215, and a shielding portion 216. Among them, the winding portion 213 is provided on the side of the first gear 311 facing the knob 211. The second transmission engaging portion 3111 is provided on the side of the center of the first gear 311 facing the knob 211. To avoid affecting the winding of the lifting member 22, the second transmission engaging portion 3111 is provided in the hollow of the winding portion 213. The winding portion 213 passes through the first through hole 111 in the first side wall 11. The shielding portion 216 is fixed to the outer periphery of the first through hole 111 and shields the winding portion 213. The second concave-convex structure 2162 is provided on the side of the shielding portion 216 facing the knob 211. The first transmission engaging portion 2112 is provided on the side of the center of the knob 211 facing the first gear 231. The first concave-convex structure 2111 is annularly provided along the outer periphery of the first transmission engaging portion 2112 on the surface of the knob 211 facing the box body 1. The first gear 311 and the rotating shaft 212 are rotatably installed on the first side wall 11 of the box body 1, and finally the combination installation of the lifting mechanism 2 and the reset mechanism 3 is realized.

[0123] In use, when the lifting mechanism 2 needs to be reset, the knob 211 is pulled outwards to drive the first concave-convex structure 2111 thereon to separate from the second concave-convex structure 2162 and the first transmission engaging part 2112 to separate from the second transmission engaging part 3111. At this time, the coil spring 321 releases the elastic tightening force to drive the second gear 312 to rotate reversely, and then drives the first gear 311 engaged therewith to rotate reversely, thereby driving the winding part 213 connected to the first gear 311 to rotate reversely to release the lifting member 22 wound on the winding part 213. The lifting member 22 moves back under the action of gravity, and finally the reset of the lifting mechanism 2 is realized.

[0124] It should be noted that during the process of the lifting mechanism 2 driving the article 100 in the box body 1 to rise, the first concave-convex structure 2111 and the second concave-convex structure 2162 can remain separated, but the first transmission engaging part 2112 and the second transmission engaging part 3111 need to maintain concave-convex engagement to elastically tighten the coil spring 321 in the reset mechanism 3 while the lifting mechanism 2 drives the article 100 to move. Therefore, when the knob 211 of the present application is pulled outwards, it has two positions. The first position is that the first concave-convex structure 2111 is separated from the second concave-convex structure 2162, and at the same time, the first transmission engaging part 2112 and the second transmission engaging part 3111 maintain concave-convex engagement; the second position is that the first concave-convex structure 2111 is separated from the second concave-convex structure 2162, and at the same time, the first transmission engaging part 2112 and the second transmission engaging part 3111 are separated.

[0125] When the lifting mechanism 2 needs to drive the article 100 to rise, a force F1 is applied to pull the knob 211 outwards to make it reach the first position. When the lifting mechanism 2 needs to be reset, a force F2 (F2 > F1) is applied to pull the knob 211 outwards to make it reach the second position.

[0126] Specifically, the engagement depth between the first transmission engaging part 2112 and the second transmission engaging part 3111 is greater than the engagement depth between the first concave-convex structure 2111 and the second concave-convex structure 2162, so that under the action of the force applied to the lifter 21, the knob 211 can reach the first position and the second position.

[0127] To facilitate the understanding of the storage box of this embodiment, the following is an introduction to its usage process in combination with Figure 1 to Figure 5 the attached drawings of the specification:

[0128] When it is necessary to adjust the height of the article 100, pull out the knob 211 outward until it reaches the first position (the first concavo-convex structure 2111 disengages from the second concavo-convex structure 2162, and the first transmission engaging portion 2112 and the second transmission engaging portion 3111 remain in a concavo-convex engagement state), the elastic member 215 is compressed and deformed, then rotate the knob 211, and drive the first gear 311 to rotate through the concavo-convex engagement of the first transmission engaging portion 2112 and the second transmission engaging portion 3111, thereby driving the winding portion 213 to rotate together to wind the lifting member 22 around the winding portion 213, so as to drive the article 100 in the box body 1 to move upward. At the same time, the first gear 311 drives the second gear 312 meshing with it to rotate, and the second gear 312 drives the winding spring 321 to elastically contract along its central end. When the limit protrusion 3112 on the first gear 311 abuts against the second limiting portion 114, the first gear 311 cannot continue to rotate, and further the cooperating knob 211 and the winding portion 213 cannot continue to rotate. At this time, the lifting member 22 moves to the maximum displacement, and the article 100 in the box body 1 rises to the maximum height;

[0129] After the article 100 reaches the specified height, remove the force applied to the knob 211. The deformation force of the elastic member 215 drives the knob 211 to fit against the first side wall 11 of the box body 1, so that the first concavo-convex structure 2111 is tightly engaged with the second concavo-convex structure 2162, and the two are engaged and fixed to prevent the lifting member 22 from retracting, realizing the positioning of the lifter 21, and ensuring the use stability of the article 100.

[0130] When the lifting mechanism 2 needs to be reset, pull out the knob 211 outward to make it reach the second position (the first concave-convex structure 2111 disengages from the second concave-convex structure 2162, and the first transmission engaging portion 2112 and the second transmission engaging portion 3111 are separated), the elastic member 215 is compressed and deformed, the winding spring 321 releases the elastic tightening force to drive the second gear 312 to rotate in the reverse direction, and then drives the first gear 311 meshing with it to rotate in the reverse direction, thereby driving the winding portion 213 connected to the first gear 311 to rotate in the reverse direction together to release the lifting member 22 from the winding portion 213. The lifting member 22 descends under its own gravity. When the limiting protrusion 3112 on the first gear 311 abuts against the first limiting portion 113, the first gear 311 cannot continue to rotate in the reverse direction, and further the winding portion 213 cannot continue to rotate in the reverse direction. At this time, the lifting member 22 descends to the initial position (such as the bottom of the box body 1). At the same time, the second gear 312 meshing with the first gear 311 also cannot continue to rotate in the reverse direction, and the winding spring 321 cannot continue to release the elastic tightening force, so that the winding spring 321 maintains the initial elastic tightening force. Remove the force applied to the knob 211, and the deformation force of the elastic member 215 drives the knob 211 to fit against the first side wall 11 of the box body 1, so that the first concave-convex structure 2111 is tightly engaged with the second concave-convex structure 2162, and the first transmission engaging portion 2112 and the second transmission engaging portion 3111 are engaged.

[0131] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
