In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0064] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0065] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0066] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0067] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

A first feature being "below", "below" and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0068] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0069] In daily life, storage tools and cleaning tools often need to be used together. Users need to go back and forth many times to move or take out from the storage room, and after use, they need to be transferred to the storage room or utility room one by one for neat storage, which is very time-consuming and laborious. Especially when the cleaning tool is a large vacuum cleaner for cleaning courtyards and streets, and the storage tool is a tool box or tool cart that can store small devices, then the process of moving the storage tools and cleaning tools out of the storage room and putting them back into the storage room will be more cumbersome and inconvenient.

[0070] See also Figure 1 Based on this, the present application provides a stacking system 100, which includes multiple stacking members 1. A first matching structure 20 is provided on the top of the stacking member 1 and / or a second matching structure 50 is provided on the bottom of the stacking member 1. The first matching structure 20 and the second matching structure 50 located on different stacking members 1 can match with each other, so that different stacking members 1 are stacked and connected up and down.

[0071] With such an arrangement, a plurality of stacking members 1 can be stacked and connected up and down, and can thus be transported and moved at the same time. They can remain stable during the transport and movement process and are not prone to slipping or separation, thereby saving transportation time and making better use of the storage space.

[0072] Further, when the top of the stacking member 1 is provided with the first matching structure 20 and the bottom is provided with the second matching structure 50, the upper and lower sides of the stacking member 1 can be stacked and connected with another stacking member 1 respectively. When only the top of the stacking member 1 is provided with the first matching structure 20, the stacking member 1 can only be stacked and connected below another stacking member 1. Similarly, when only the bottom of the stacking member 1 is provided with the second matching structure 50, the stacking member 1 can only be stacked and connected above another stacking member 1.

[0073] It can be understood that the stacking piece 1 includes but is not limited to a storage tool or a cleaning tool.

[0074] See also Figure 1 and Figure 2In one embodiment, at least one stacking member 1 is a vacuum cleaner or at least one stacking member 1 is also provided with a vacuuming function. The vacuum cleaner can be stacked and connected above or below another stacking member 1 through the first matching structure 20 at the top and / or the second matching structure 50 at the bottom, thereby achieving common movement and storage, saving time and energy.

[0075] See also Figure 1 and Figure 2 For example, in one embodiment, the vacuum cleaner includes a box-shaped vacuum main body 116 and a vacuum pipe 117 detachably mounted on the vacuum main body 116. At least a portion of the vacuum pipe 117 can be wound around the outer peripheral wall of the vacuum main body 116 or stored in the vacuum main body 116. A first matching structure 20 is disposed on the top of the vacuum main body 116, and a second matching structure 50 is disposed on the bottom of the vacuum main body 116.

[0076] With such arrangement, the upper and lower parts of the vacuum cleaner can be freely stacked and connected with other stacking members 1. For example, the vacuum cleaner can be stacked and connected above or below a stacking member 1, or can be stacked and connected between two stacking members 1. It can be understood that in other embodiments, according to different stacking requirements, the vacuum cleaner body 116 can also be provided with the first matching structure 20 only on the top or the second matching structure 50 only on the bottom.

[0077] Specifically, the dust collecting body 116 includes a box-shaped shell, a dust collecting module and an energy storage module, both of which are installed in the shell, and the energy storage module is electrically connected to the dust collecting module. It can be understood that the first matching structure 20 or the second matching structure 50 is arranged on the shell.

[0078] For example, in this embodiment, the outer peripheral wall of the shell is provided with a concave portion in an annular direction, and the dust suction pipe 117 can be wound around and embedded in the concave portion. Furthermore, a storage area is provided in the shell, and the dust suction pipe 117 is provided in various types according to different usage scenarios and requirements. Different types of dust suction pipes 117 can be partially wound around the concave portion of the outer peripheral wall of the shell, or partially stored in the storage area in the shell for replacement.

[0079] Furthermore, the vacuum cleaner also includes a power cord electrically connected to the energy storage module, and a wire take-up post 118 is protruding from the outer peripheral wall of the shell, and the power cord can extend out of the shell and be taken up on the wire take-up post 118.

[0080] Please see again Figure 1 and Figure 2For ease of understanding, in the present application, when multiple stacking members 1 are stacked on each other, the stacking member 1 located relatively to the upper one is named as the first stacking member 10, and the stacking member 1 located relatively to the lower one is named as the second stacking member 40. In other words, both the first stacking member 10 and the second stacking member 40 are stacking members 1. When multiple stacking members 1 are stacked and connected to each other, every two stacking members 1 are stacked, and the stacking member 1 located on the upper side is the first stacking member 10, and the stacking member 1 located relatively to the lower side is the second stacking member 40. For example, when three stacking members 1 are stacked and connected to each other, the stacking member 1 in the middle can be called the first stacking member 10 relative to the stacking member 1 located above it, and can be called the second stacking member 40 relative to the stacking member 1 located below it. It can be understood that the naming of the first stacking member 10 and the second stacking member 40 is only for the purpose of facilitating the understanding of the matching relationship and matching process between the first matching structure 20 and the second matching structure 50.

[0081] That is, when a plurality of stacking members 1 are stacked on each other, the first matching structure 20 is disposed on the top of the first stacking member 10 , and the second matching structure 50 is disposed on the bottom of the second stacking member 40 .

[0082] In one embodiment of the present application, the first matching structure 20 and the second matching structure 50 cooperate with each other to at least limit the movement of the first stacking member 10 and the second stacking member 40 along the Z direction. The Z direction is also the direction in which the stacking members 1 are connected and stacked.

[0083] In one embodiment of the present application, the first matching structure 20 and the second matching structure 50 cooperate with each other, and can also limit the movement of the first stacking member 10 and the second stacking member 40 along the X direction and / or the Y direction. For example, one of the first matching structure and the second matching structure is a groove with a notch perpendicular to the Z direction, and the other is a protrusion, and the concave and convex are plugged together to limit the movement of the first stacking member 10 and the second stacking member 40 along the Z direction and the X direction or the Z direction and the Y direction.

[0084] Furthermore, in one embodiment of the present application, a third matching structure 30 is further provided at another location on the top of the first stacking member 10, and a fourth matching structure 60 adapted to the third matching structure 30 is further provided at another location on the bottom of the second stacking member 40. When the first matching structure 20 and the second matching structure 50 are matched with each other, and the third matching structure 30 and the fourth matching structure 60 are matched with each other, the movement of the first stacking member 10 and the second stacking member 40 along the X direction, the Y direction and the Z direction are all restricted. In this way, the reliability of the stacking connection between the stacking members can be further ensured, and the transportation and storage can be made safer and more stable, and it is not easy for some stacking members to slip and fall and cause injuries to people.

[0085] Further, at least one set of first matching structures 20 and third matching structures 30 are arranged on both sides of the top X direction of the first stacking member 10, and the structure of the third matching structure 30 is the same as that of the first matching structure 20 and is arranged opposite to each other; at least one set of second matching structures 50 and fourth matching structures 60 are arranged on both sides of the bottom X direction of the second stacking member 40, and the structure of the fourth matching structure 60 is the same as that of the second matching structure 50 and is arranged opposite to each other; and / or, at least one set of first matching structures 20 and third matching structures 30 are arranged on both sides of the top Y direction of the first stacking member 10, and the structure of the third matching structure 30 is the same as that of the first matching structure 20 and is arranged opposite to each other; at least one set of second matching structures 50 and fourth matching structures 60 are arranged on both sides of the bottom Y direction of the second stacking member 40, and the structure of the fourth matching structure 60 is the same as that of the second matching structure 50 and is arranged opposite to each other.

[0086] In one embodiment, the third matching structure 30 has the same structure as the first matching structure 20 and is axially symmetrically arranged, and the fourth matching structure 60 has the same structure as the second matching structure 50 and is axially symmetrically arranged.

[0087] Furthermore, in one embodiment, the third matching structure 30 has the same structure as the first matching structure 20 and is symmetrically arranged about the central axis of the first stacking member 10 , and the fourth matching structure 60 has the same structure as the second matching structure 50 and is symmetrically arranged about the central axis of the second stacking member 40 .

[0088] Further, in one embodiment, the third matching structure 30 has the same structure as the first matching structure 20 and is axially symmetrically arranged on two opposite sides of the first stack 10 with respect to the central axis of the first stack 10, and the fourth matching structure 60 has the same structure as the second matching structure 50 and is axially symmetrically arranged on two opposite sides of the second stack 40 with respect to the central axis of the second stack 40. It can be understood that in other embodiments, the third matching structure 30 and the first matching structure 20 can also be arranged relative to each other with respect to other axes of the first stack 10, and it can be understood that the relative arrangement includes but is not limited to an axisymmetric arrangement, and can also be located on both sides of the axis but diagonally arranged.

[0089] It is understandable that the first matching structure 20 and the third matching structure 30 may be located on the same height plane or on different height planes. In other words, the two locations where the first matching structure 20 and the third matching structure 30 are arranged on the first stack 10 may have a height difference.

[0090] Please see again Figure 1 and Figure 2In order to facilitate structural processing and stacking operations, in one embodiment, a group of first matching structures 20 and third matching structures 30 are arranged on both sides of the top X direction of the first stacking member 10, and the structure of the third matching structure 30 is the same as that of the first matching structure 20; at the same time, correspondingly, a group of second matching structures 50 and fourth matching structures 60 are arranged on both sides of the bottom X direction of the second stacking member 40, and the structure of the fourth matching structure 60 is the same as that of the second matching structure 50 and is arranged opposite to each other.

[0091] It can be understood that in other embodiments, one or more groups of first matching structures 20 and third matching structures 30 may be respectively arranged on both sides of the top of the first stack 10 in the X direction and both sides of the Y direction; correspondingly, one or more groups of second matching structures 50 and fourth matching structures 60 may be respectively arranged on both sides of the top of the second stack 40 in the X direction and both sides of the Y direction. Specific examples are not given in detail.

[0092] For example, in one embodiment, the first matching structure 20 and the third matching structure 30 may also be provided in two groups, wherein one group of the first matching structure 20 and the third matching structure 30 are provided on both sides of the top of the first stack 10 in the X direction, and the other group is provided on both sides of the top of the first stack 10 in the Y direction; the second matching structure 50 and the fourth matching structure 60 are also provided in two groups accordingly, wherein one group of the second matching structure 50 and the fourth matching structure 60 are provided on both sides of the bottom of the second stack 40 in the X direction, and the other group is provided on both sides of the bottom of the second stack 40 in the Y direction.

[0093] Furthermore, in other embodiments, the third matching structure 30 may also be different from the first matching structure 20, and the fourth matching structure 60 may also be different from the second matching structure 50, as long as the third matching structure 30 and the fourth matching structure 60 can match with each other and can limit the movement between the first stacking member 10 and the second stacking member 40 in the X direction, Y direction and Z direction together with the first matching structure 20 and the second matching structure 50.

[0094] For example, in one embodiment, the third matching structure 30 includes a first matching portion disposed at the top of the first stacking member 10, and the fourth matching structure 60 includes a second matching portion disposed at the bottom of the second stacking member 40. When the second stacking member 40 is stacked on the first stacking member 10, the first matching portion can be mutually engaged with the second matching portion to cooperate with the first matching structure 20 and the second matching structure 50 to simultaneously limit the movement of the second stacking member 40 along the X direction, the Y direction, and the Z direction. It can be understood that the first matching portion and the second matching portion can both be configured as a card plate to be mutually engaged, or one can be a groove and the other can be a protrusion to be mutually engaged.

[0095] It can be further understood that, in one embodiment, the stacking system 100 further includes a fifth matching structure 12 and a sixth matching structure 41, the fifth matching structure 12 is arranged at the top of the first stacking member 10, and the sixth matching structure 41 is arranged at the bottom of the second stacking member 40, and when the second stacking member 40 is stacked on the first stacking member 10, the fifth matching structure 12 and the sixth matching structure 41 can cooperate with each other to limit the movement of the second stacking member 40 along the X direction and the Y direction. In other words, on the basis of the mutual cooperation of the first matching structure 20, the second matching structure 50, the third matching structure 30 and the fourth matching structure 60, other matching structures can be added according to needs to further assist in limiting, so as to ensure that after the first stacking member 10 and the second stacking member 40 are stacked and connected, relative displacement between the two is not likely to occur.

[0096] The following further describes the method and structure for realizing stacking connection between the stacking components 1.

[0097] See also Figures 1 to 24 , illustratively, referring to the first embodiment of the present application, in this embodiment, the stacking system 100 includes three stacking members 1, which are a vacuum cleaner, a storage box, and a cart from top to bottom. Optionally, the storage box and the vacuum cleaner are both rectangular parallelepipeds, and both are the same size. It can be understood that in other embodiments, the specific function of the stacking member 1 is not limited, and the stacking member 1 can be a storage box, a cart, a vacuum cleaner, or a storage basket, etc., and the specific size is not limited.

[0098] For ease of understanding, the vacuum cleaner and the storage box in this embodiment are taken as examples to illustrate the matching structure and matching state of the first matching structure 20 and the second matching structure 50. In this embodiment, the storage box is the first stacking member 10 relative to the vacuum cleaner, and the vacuum cleaner is the second stacking member 40 relative to the storage box. It can be understood that if the stacking connection between the storage box and the cart is taken as an example to illustrate the matching structure and matching state of the first matching structure 20 and the second matching structure 50, the storage box is the second stacking member 40 relative to the cart, and the cart is the first stacking member 10 relative to the storage box.

[0099] In the present application, the stacking system has a locked state, in which the first stacking member and the second stacking member can be locked in three directions, X, Y, and Z, by the pressure located on the upper stacking member. The "pressure" may be only the gravity generated by the upper stacking member 1 itself, or the pressure generated by the gravity generated by the upper stacking member 1 itself and the external force applied to the upper stacking member 1.

[0100] For example, in this embodiment, the X direction, the Y direction, and the Z direction correspond to the length direction, the width direction, and the height direction of the storage box, respectively; it should be noted that in this embodiment, the height direction is also the stacking extension direction between the first stacking member 10 and the second stacking member 40. It can be understood that when the storage box is in the shape of a polygonal prism or a cylinder, the X direction, the Y direction, and the Z direction can be determined according to the specific situation.

[0101] It can be understood that in the same stacking system 100, when the X-direction, Y-direction, and Z-direction coordinate systems are determined, the correspondence between the length direction, width direction, and height direction of different stacking components and the X-direction, Y-direction, and Z-direction is related to the length, width, height, and placement direction of the stacking component, and needs to be corresponded according to specific circumstances. For example, in the same X-direction, Y-direction, and Z-direction coordinate system, the length direction, width direction, and height direction of the first stacking component 10 can correspond to the X-direction, Y-direction, and Z-direction, respectively, while the length direction, width direction, and height direction of the second stacking component 40 can correspond to the Y-direction, X-direction, and Z-direction, respectively.

[0102] For example, in the first embodiment provided in the present application, the first matching structure 20 includes a first elastic member 21 and a first movable member 22, the first elastic member 21 can elastically act on the first movable member 22, when the second stacking member 40 is stacked on the first stacking member 10, the first movable member 22 can move on the first stacking member 10 under the pressure of the second stacking member 40; when the second stacking member 40 is stacked in place, the first movable member 22 can make the first movable member 22 and the second matching structure 50 mutually engaged under the elastic action of the first elastic member 21, so as to achieve a locked state through the pressure of the second stacking member 40. It should be noted that in this embodiment, the pressure refers to the gravity generated when the second stacking member 40 is placed.

[0103] In this way, during the stacking process, the second stacking member 40 only needs to be directly moved and placed on the first stacking member 10, and the locking state can be automatically formed by the pressure generated by the weight of the second stacking member 40, which reduces the complexity of the locking operation and effectively improves the work efficiency and the convenience of stacking positioning. In other words, in this embodiment, the stacking system 100 can achieve gravity self-locking through the weight of the upper one.

[0104] Further, in the first embodiment of the present invention, the first movable member 22 is slidably connected to the first stacking member 10. It can be understood that the sliding connection is convenient to operate and relatively stable. Optionally, the sliding direction of the first movable member 22 is consistent with the X direction or the Y direction. In other words, in this embodiment, the first movable member 22 can slide toward the outside of the first stacking member 10 along the X direction or the Y direction of the first stacking member 10. It should be emphasized that in this embodiment, the X direction refers to the length direction of the first stacking member 10, the Y direction refers to the width direction of the first stacking member 10, and the Z direction refers to the height direction of the first stacking member 10.

[0105] Please see again Figures 1 to 18 Optionally, in the present embodiment, the first movable member 22 can move along the X direction (length direction) of the first stacking member 10; the first movable member 22 includes a base 221 and a first clamping portion 222 arranged on the base 221, the base 221 can be slidably connected to the first stacking member 10, and the second matching structure 50 includes a second clamping portion 51 arranged on the second stacking member 40. In the locked state, the first clamping portion 222 can be mutually engaged with the second clamping portion 51 under the action of the first elastic member 21, so as to at least limit the second stacking member from separating from the first stacking member along the Z direction.

[0106] It can be understood that the specific structures of the first clamping portion 222 and the second clamping portion 51 can be changed according to the needs to simultaneously restrict the second stacking member from moving relative to the first stacking member 10 in the X direction and / or the Y direction. Correspondingly, the third matching structure 30 and the fourth matching structure 60 can supplement the restriction of the movement of the second stacking member 40 in other directions to ensure that in the locked state, the first stacking member 10 and the second stacking member 40 cannot be relatively displaced in the three directions of X, Y, and Z.

[0107] It should be noted that, optionally, in this embodiment, the first clamping portion 222 is convexly provided on the base 221, and the second clamping portion 51 is convexly provided on the bottom of the second stacking member 40. It can be understood that the convexly provided is relative and does not mean protruding from the entire surface of the base 221 or the bottom of the second stacking member 40. The meaning of the convexly provided will not be further described below, as long as the desired function can be achieved.

[0108] Please see again Fig. 9 Optionally, in this embodiment, the second clamping portion 51 may or may not protrude from the bottom of the second stacking member 40, as long as the overall structure of the bottom of the second stacking member 40 does not affect the automatic gravity locking of the second stacking member 40 when it is stacked on the first stacking member 10. For example, in this embodiment, a concave area (not numbered) may be provided at the bottom of the second stacking member 40, and the second clamping portion 51 is convexly provided in the concave area, but does not protrude from other parts of the bottom of the second stacking member 40.

[0109] Please see again Figures 5 to 10 It can be understood that, in order to facilitate the engagement between the first card portion 222 and the second card portion 51, one of the first card portion 222 and the second card portion 51 may have a pin, and the other may have a slot 511, and the slot 511 may have one notch or multiple notches to selectively limit the moving direction of the second stacking member 40 according to requirements. In other words, the slots 511 of different shapes cooperate with the pins to correspondingly limit the movement of the second stacking member 40 in one or more directions.

[0110] Please see again Figures 5 to 10 For example, in this embodiment, the first clamping portion 222 has a pin (not numbered), and the second clamping portion 51 has a slot 511; in the locked state, the pin of the first clamping portion 222 can be inserted into the slot 511 under the action of the first elastic member 21. Please refer again Figure 5 Furthermore, in the present embodiment, the slot 511 is a concave slot, that is, the slot 511 has only one slot, so that the side walls around the slot 511 can all play a limiting role, wherein the upper and lower side walls of the slot 511 can limit the second stacking member 40 from moving along the Z direction, and the left and right side walls of the slot 511 can limit the second stacking member 40 from moving along the Y direction; the side wall of the slot 511 opposite to the slot can limit the second stacking member 40 from moving along the X direction toward the side away from the slot.

[0111] It is understandable that in other embodiments, the slot 511 may also have only upper and lower side walls, so that the movement of the second stacking member 40 along the Z direction can be selectively limited. Correspondingly, the movement of the second stacking member along the X direction and the Y direction can be limited by the cooperation of the third cooperation structure 30 and the fourth cooperation structure 60.

[0112] Please see again Figures 1 to 10 In this embodiment, a movable groove 11 is provided on the top of the first stacking member 10, and the movable groove 11 is used to install the first movable member 22. The movable groove 11 has a first slot 111 and a second slot 112 that are connected to each other. The first slot 111 is provided on the side wall of the first stacking member 10, and the second slot 112 is provided on the top wall of the first stacking member 10. The first movable member 22 can move in the direction of the first slot 111.

[0113] Please see again Figure 8 It should be noted that the side wall of the movable groove 11 opposite to the first notch 111 is the first side wall 113, the two side walls opposite to the movable groove 11 are both the second side walls 114, and the bottom wall opposite to the second notch 112 is the first bottom wall 115. It can be understood that in this embodiment, the setting direction of the first elastic member 21 is toward the first side wall 113, in other words, the setting direction of the first elastic member 21 is parallel to the length direction of the first stacking member 10.

[0114] For further information, see Figures 1 to 10 In this embodiment, the third matching structure 30 has the same structure as the first matching structure 20 and is arranged opposite to each other, and the fourth matching structure 60 has the same structure as the second matching structure 50 and is arranged opposite to each other. Such arrangement facilitates the rapid stacking and locking of the first stacking member 10 and the second stacking member 40. Since the specific structures of the third matching structure 30 and the fourth matching structure 60 are the same as those of the first matching structure 20 and the second matching structure 50, the matching process of the two will not be described in detail here.

[0115] Further, in one embodiment of the present invention, the second clamping portion 51 can be abutted against the first side wall 113 on the side opposite to the notch of the slot 511. In this way, the second clamping portion 51 of the second matching structure 50 and the second clamping portion 51 of the fourth matching structure 60 can cooperate with each other to ensure that the movement of the second stacking member 40 along the X direction is restricted, and ensure that in the locked state, after the first clamping portion 222 and the second clamping portion 51 are mutually engaged, the first stacking member 10 and the second stacking member 40 can be stably stacked and cannot be relatively separated in the X direction, the Y direction and the Z direction.

[0116] It can be understood that in other embodiments, the side of the second clamping portion 51 opposite to the notch of the insertion slot 511 may not be abutted against the first side wall 113, and the movement of the second stacking member 40 along the X direction can be relatively limited by other means; for example, an additional abutting protrusion is provided at the bottom of the second stacking member 40 corresponding to the first matching structure 20 and the third matching structure 30, wherein the abutting protrusion corresponding to the first matching structure 20 can abut against the first side wall 113 of the movable groove 11 at the first matching structure 20, and in the locked state, the abutting protrusion can limit the movement of the second stacking member 40 in the X direction toward the third matching structure 30; further, in the locked state, the abutting protrusion corresponding to the third matching structure 30 can abut against the first side wall 113 of the movable groove 11 at the third matching structure 30, and the abutting protrusion can limit the movement of the second stacking member 40 in the X direction toward the first matching structure 20; in this way, without relying on the second clamping portion 51, it can still be ensured that the movement of the first stacking member 10 and the second stacking member 40 in the X direction is effectively limited.

[0117] It can be understood that as long as the abutting protrusion can cooperate with the side wall of the movable groove 11 to limit the movement of the second stacking member 40 along the X direction, the setting position of the abutting protrusion can be flexibly changed, and can be set separately or integrated with other structures.

[0118] Please see again Figures 1 to 10 , and see also Fig.19 and Fig.21, in order to facilitate the first movable member 22 to move under the gravity of the second stacking member 40. Optionally, in this embodiment, the first clamping portion 222 has a first guiding slope 2221, and the first guiding slope 2221 is used to guide when the first clamping portion 222 is inserted into the slot 511. Specifically, the first guiding slope 2221 is arranged on a side of the first clamping portion 222 relatively away from the base 221.

[0119] Please see again Fig. 9 and Fig.10 Further, the second clamping portion 51 has a second guiding slope 512, and the second guiding slope 512 is used for guiding when the first clamping portion 222 is inserted into the slot 511. Specifically, the second guiding slope 512 is arranged on a side of the second clamping portion 51 that is relatively far away from the second stacking member 40. With such arrangement, in this embodiment, when the second stacking member 40 is placed on the first stacking member 10, under the action of the gravity of the second stacking member 40, the second guiding slope 512 of the second clamping portion 51 can cooperate with the first guiding slope 2221 of the first clamping portion 222, so that the first clamping portion 222 can quickly enter the slot 511 to form a locked state.

[0120] In other words, when the second stacking member 40 is stacked and placed on the first stacking member 10, the second clamping portion 51 can squeeze the first clamping portion 222 under the action of the gravity of the second stacking member 40 and the first guide slope 2221 and the second guide slope 512, so that the first movable member 22 can slide out of place on the first stacking member 10, thereby allowing the second stacking member 40 to be stacked in place and fit together with the second stacking member 40. After the second stacking member 40 is stacked in place, the first clamping portion 222 can be quickly inserted into the slot 511 under the elastic action of the first elastic member 21, thereby realizing a complete locking process.

[0121] Please see again Fig.19 Optionally, in the present embodiment, the base 221 is provided with two first clamping portions 222, and the two first clamping portions 222 are arranged at intervals. Such a configuration can further increase the reliability of the clamping connection.

[0122] Please see again Fig.19 and Fig.21 Optionally, in this embodiment, the first movable member 22 further includes an auxiliary portion 223, which is disposed on the base 221 and located between the two first clamping portions 222, and is used to provide a force application position, so that it is convenient for the user to apply force to pull the first movable member 22.

[0123] It is understandable that the auxiliary portion 223 can be a convex edge portion provided on the base 221, or other characteristic portions that can assist in pulling the base 221 to move, such as a groove portion, or a silicone portion or rubber portion with a relatively rough surface.

[0124] Optionally, in this embodiment, two or three of the base 221, the first clamping portion 222, and the auxiliary portion 223 are integrally formed. This arrangement can facilitate processing.

[0125] Please see again Figures 5 to 7 It should be noted that, in the first embodiment of the present invention, the first matching structure 20 is located in the middle of the width side of the first stacking member 10, and it can be understood that the movement direction of the first movable member 22 is perpendicular to the width side. In other embodiments, the position of the first matching structure 20 can be set according to needs, and it can also be set on the length side, or not in the middle.

[0126] It can be understood that, according to requirements, the structure of the third matching structure 30 can be the same as that of the first matching structure 20 , or can be different from the structure of the first matching structure 20 .

[0127] Please see again Figure 8 , Fig.13 and Fig.14 Furthermore, in this embodiment, the stacking system 100 further includes a mounting seat 90, and the first elastic member 21 is mounted on the first stacking member 10 through the mounting seat 90. This can make the position of the first elastic member 21 more stable, thereby ensuring the stability of the sliding direction of the first movable member 22.

[0128] Specifically, the mounting seat 90 is fixed on the first bottom wall 115 of the movable groove 11. It can be understood that the mounting seat 90 can be integrally formed with the first bottom wall 115, or can be independently formed and then installed on the first bottom wall 115; further, the mounting seat is an L-shaped structure, including a first mounting plate attached to the first bottom wall 115 and a second mounting plate perpendicular to the first mounting plate. One end of the first elastic member 21 abuts against the second mounting plate of the mounting seat 90, and the other end abuts against the first movable member 22, so that the first elastic member 21 can drive the first movable member 22 to move more stably.

[0129] Furthermore, in order to further ensure the installation stability of the first elastic member 21 and the sliding stability of the first movable member, a slide groove 225 is provided in the first movable member 22, and the first elastic member 21 and the mounting seat 90 can be located in the slide groove 225 to ensure that the mounting seat 90 and the slide groove 225 can cooperate with each other, so that the first elastic member 21 can more stably and reliably drive the first movable member 22 to slide. Exemplarily, in this embodiment, the slide groove 225 includes a first groove area and a second groove area connected to each other, the first groove area is used to accommodate the second mounting plate of the mounting seat 90, and the second groove area is used to accommodate the first mounting plate of the mounting seat 90 and the first elastic member 21 located on the first mounting plate, so as to ensure that the first movable member 22 can slide back and forth on the first bottom wall 115.

[0130] In this embodiment, the two opposite side walls of the movable groove 11 are provided with a first limiting portion 1141, and the corresponding two sides of the first movable member 22 are provided with a second limiting portion 2212. The first limiting portion 1141 and the second limiting portion 2212 cooperate with each other to limit the moving distance or rotation range of the first movable member 22.

[0131] In this embodiment, after the second stacking member 40 is stacked on the first stacking member 10, the first movable member 22 can move on the first stacking member 10 and does not protrude from the side wall of the first stacking member 10. This arrangement can avoid or reduce the risk of being unable to lock or unable to unlock due to the limited movement distance or range of the first movable member 22 in a narrow space.

[0132] It is understandable that in other embodiments, without affecting the mutual stacking and locking of the first stacking member 10 and the second stacking member 40, after the second stacking member 40 is stacked onto the first stacking member 10, the first movable member 22 can also move on the first stacking member 10 and protrude from the side wall of the first stacking member 10.

[0133] Please see again Figures 1 to 24 In this embodiment, the stacking system 100 also includes an unlocked state, in which the second stacking member 40 can be separated from the first stacking member 10; the stacking system 100 also includes a positioning component 80, and when the positioning component 80 is in the positioning position, the stacking system 100 forms an unlocked state.

[0134] For further information, please see Figures 1 to 10 In this embodiment, the positioning assembly 80 is disposed on the first matching structure 20. Under the action of external force, the first matching structure 20 can drive the positioning assembly 80 to move to the positioning position, so that the stacking system 100 can switch from the locked state to the unlocked state. The positioning assembly 80 is disposed on the first matching structure 20, so that the positioning assembly 80 and the first matching structure 20 can be kept synchronized, which is convenient for operation and can quickly form an unlocked state. It can be understood that in other embodiments, the positioning assembly 80 can also be disposed on the first stacking member 10 and / or the second stacking member 40.

[0135] Furthermore, in this embodiment, the positioning assembly 80 includes a positioning member 81 and a second elastic member 82, the second elastic member 82 elastically acts on the positioning member 81, and the second stacking member 40 is also provided with a positioning matching portion 70. When the positioning assembly 80 follows the first movable member 22 to move to the positioning position, the positioning member 81 can be supported against the positioning matching portion 70 under the elastic action of the second elastic member 82 to prevent the first elastic member 21 from driving the first movable member 22 to move.

[0136] In this embodiment, the base 221 is provided with a first assembly groove 2211, and the positioning component 80 can be movably installed in the first assembly groove 2211; in the locked state, the positioning member 81 can rotate into the first assembly groove 2211 and compress the second elastic member 82 under the pressure of the positioning matching part 70; in the unlocked state, the first movable member 22 drives the positioning component 80 to move to the positioning position under the action of external force, and the positioning member 81 can be clamped on the positioning matching part 70 under the elastic action of the second elastic member 82 to prevent the first elastic member 21 from driving the base 221 to slide. It can be understood that the external force can be removed after the positioning component 80 reaches the positioning position. At this time, the positioning member 81 is clamped on the positioning matching part 70 under the elastic action of the second elastic member 82, so that the stacking system 100 can be kept in the unlocked state, and the user can directly move the second stacking member 40 away from the first stacking member 10.

[0137] Optionally, in this embodiment, the positioning matching portion 70 is a protrusion 71 disposed at the bottom of the second stacking member 40. In the unlocked state, the positioning member 81 can elastically abut against the outer side of the protrusion 71 under the elastic action of the second elastic member 82. It can be understood that in other embodiments, the positioning matching portion 70 can also be a side wall of the second stacking member 40.

[0138] Please see again Figures 1 to 10 , and see also Figure 22 to Figure 24 Optionally, in the present embodiment, the positioning member 81 has an inclined abutment surface 811 on the side of the first bottom wall 115 opposite to the first assembly groove 2211. When the first movable member 22 moves toward the outside of the first stacking member 10, the inclined abutment surface 811 can facilitate the positioning member 81 to quickly reach the positioning position, so that the positioning member 81 can quickly abut against the positioning matching portion 70.

[0139] It can be understood that, in the locked state, the positioning fitting portion 70 can be pressed against the inclined abutting surface 811 to prevent the positioning member 81 from rotating out of the first assembly groove 2211 under the action of the second elastic member 82 .

[0140] Please see again Fig.23 Optionally, in this embodiment, the side of the positioning member 81 abutting against the positioning matching portion 70 is an arcuate abutting surface 812. In this way, while ensuring the abutting positioning function, it is convenient for the positioning member 81 to rotate in the first assembly groove 2211. It can be understood that, correspondingly, in the unlocked state, the side of the positioning matching portion 70 and the positioning member 81 abutting against each other can also be an arcuate abutting surface. This further facilitates the abutting positioning of the two, and at the same time facilitates the positioning member 81 to rotate in the first assembly groove 2211.

[0141] Please see again Figures 1 to 10 , and see also Figure 22 to Figure 24Optionally, in this embodiment, a third limiting portion 2213 is provided on the arcuate abutting surface 812, and a fourth limiting portion 813 is provided on the groove wall of the first assembly groove 2211 corresponding to the arcuate abutting surface 812. When the positioning member 81 rotates in a direction away from the first bottom wall 115 of the first assembly groove 2211 under the elastic action of the second elastic member 82, the fourth limiting portion 813 can be blocked by the third limiting portion 2213. Such a configuration can maintain the stability of the positioning member 81 and prevent the positioning member 81 from being separated from the first assembly groove 2211.

[0142] See also Fig.24 and Fig.25 Optionally, in this embodiment, the second elastic member 82 is a tower spring. The tower spring is small in size, has a large load and a strong variable stiffness, can be used in a small space, withstands greater pressure, and has a good shock-absorbing and rebound effect. It can be understood that in other embodiments, the second elastic member 82 includes but is not limited to a tower spring, a compression spring, a torsion spring, a spring sheet, etc.

[0143] It can be understood that a plurality of groups of matching components can be arranged on the top of the first stacking member 10, each group of matching components can include one or more first matching structures 20 and one or more third matching structures 30, and each group of matching components can position a second stacking member 40. In other words, the first stacking member 10 can position a second stacking member 40 by forming a group of one or more first matching structures 20 and one or more third matching structures 30, and the number and arrangement positions of the first matching structures 20 and the third matching structures 30 required to position a second stacking member 40 can be selected according to needs, so that second stacking members 40 of different sizes and / or different numbers can be fixed on the top of the first stacking member 10.

[0144] It can be further understood that the number and setting positions of the second matching structures 50 and the fourth matching structures 60 on the second stacking component 40 do not necessarily completely correspond to the number and positions of the first matching structures 20 and the third matching structures 30 on the first stacking component 10, but only need to correspond to the first matching structures 20 and the third matching structures 30 used to fix the second stacking component 40.

[0145] Therefore, in actual mating, when the position of the first mating structure 20 on the first stacking member 10 for fixing the second stacking member 40 is determined, another or multiple structures on the first stacking member 10 that are mutually locked with the second stacking member 40 can be relatively the third mating structure 30.

[0146] It can be understood that the top of the first stacking member 10 and / or the second stacking member 40 can be flexibly arranged to fix the second stacking members 40 of different sizes accordingly.

[0147] Please see again Figure 4 and Figure 5Furthermore, in the present embodiment, the stacking system 100 further includes a reset state, in which the second stacking member 40 is separated from the first stacking member 10, the first matching structure 20 is not subjected to force, and the position of the first matching structure 20 in the reset state is the same as the position of the first matching structure 20 in the locked state. It can be understood that in other embodiments, the position of the first matching structure 20 in the locked state may also be different from the position of the first matching structure 20 in the reset state, as long as the movement of the second stacking member 40 along the X, Y, and Z directions can be effectively restricted.

[0148] Please see again Figures 1 to 10 , illustratively, in this embodiment, the fifth matching structure 12 and the sixth matching structure 41 can cooperate with each other to limit the movement of the second stacking member in the X direction and the Y direction. Specifically, the fifth matching structure 12 includes a groove opened at the top of the first stacking member 10, and the groove is located between the first matching structure 20 and the second matching structure 50. The sixth matching structure 41 includes a card block arranged at the bottom of the second stacking member 40, and the card block is located between the third matching structure 30 and the fourth matching structure 60. When the second stacking member is stacked on the first stacking member, the card block can be stuck in the groove to limit the movement of the second stacking member 40 in the X direction and the Y direction. Such a setting can limit the movement of the second stacking member 40 in the X direction while strengthening the restriction on the movement of the second stacking member 40 in the Y direction. And it can ensure that the first stacking member 10 and the second stacking member 40 are more closely stacked, and can also be stably placed independently after separation.

[0149] Optionally, in this embodiment, the groove is non-circular, and the groove has a peripheral wall around it that can play a limiting role; it can be understood that the block and the groove can correspond one to one, or one groove and multiple blocks can cooperate, as long as the movement of the second stacking member 40 can be limited in the X direction or in the X direction and the Y direction. Further, in other embodiments, the shape of the groove can also be circular, arched or other shapes.

[0150] It can be understood that in other embodiments, the fifth matching structure 12 and the sixth matching structure 41 can also be specifically implemented as other structures as long as they can assist in limiting the relative displacement between the first stacking member 10 and the second stacking member 40 .

[0151] In this embodiment, when the stacking member 1 is configured as a storage box, the storage box may be provided with a drawer (not shown) or a cabinet door (not shown) and other structures to facilitate the storage of items in the storage box or to take items out of the storage box. Optionally, the drawer is slidably mounted on one side of the storage box through a track structure. The specific structure of the cabinet door is not limited, and the opening direction of the cabinet door is not limited. It can be opened outward to the left and right, or it can be pulled upward to open. The cabinet door is also rotated to open and then slid to be stored on the top wall of the storage box. It will not be described in detail here.

[0152] In the present application, at least the outermost structure of the stacking member 1 is made of plastic material, which is easy to process as a whole and to form different structures according to different requirements, and can effectively reduce the overall cost of the stacking system. It is understood that in other embodiments, the stacking member 1 can also be made of metal structure as a whole, for example, the whole body is made of iron material. Iron material has high hardness, strong rigidity, and is not easy to damage.

[0153] See also Fig.26 and Fig. 27 The present invention also provides a second embodiment. The inventive concept and most of the structures of the second embodiment are the same as those of the first embodiment, except that: in the second embodiment, the first elastic member 21 is connected to one of the second side walls 114 of the movable groove 11, and the sliding direction of the first movable member 22 is the same as the width direction of the first stacking member 10, that is, the first movable member can slide along the Y direction.

[0154] See also Figures 28 to 34 The present invention further provides a third embodiment. The inventive concept and most structures of the third embodiment are the same as those of the first embodiment, except that in the third embodiment, the first movable member 22 is rotatably connected to the first stacking member 10.

[0155] In the third embodiment, the first movable member 22 includes a rotating seat 224 and a first clamping portion 222 arranged on the rotating seat 224, the rotating seat 224 is rotatably connected to the first stacking member 10, and the second matching structure 50 includes a second clamping portion 51 arranged on the second stacking member 40, and the second clamping portion 51 is provided with a slot 511; in the locked state, the first clamping portion 222 can be inserted into the slot 511 under the elastic action of the first elastic member 21 to limit the second stacking member 40 from being separated from the first stacking member 10 along the X direction, the Y direction and the Z direction.

[0156] Furthermore, the rotating seat 224 is provided with a second assembly groove 2241, and the positioning component 80 can be movably installed in the second assembly groove 2241; in the locked state, the positioning member 81 can be located on the side of the positioning matching portion 70 relatively away from the second stacking member 40; in the unlocked state, the first movable member 22 drives the positioning component 80 to move to the positioning position under the action of external force, and the positioning member 81 can abut against the positioning matching portion 70 under the elastic action of the second elastic member 82 to prevent the first elastic member 21 from driving the rotating seat 224 to rotate.

[0157] See also Fig.30 In the present embodiment, the positioning fitting portion 70 is a foot 72 disposed at the bottom of the second stacking member 40, and the foot 72 includes a connecting portion 721 and a hook portion 722 disposed at the bottom end of the connecting portion 721; in the unlocked state, the positioning member 81 can be driven by the rotating seat 224 to latch on a side of the hook portion 722 that is relatively close to the second stacking member 40.

[0158] Furthermore, the hook portion 722 has a third guide slope 7221 on a side relatively away from the second stacking member 40. When the unlocking state is formed, the third guide slope 7221 is used to guide when the rotating seat 224 drives the positioning member 81 to rotate. In other words, when unlocking is required, the third guide slope 7221 can facilitate the rotating member to drive the positioning member 81 to rotate to the positioning position, so as to prevent the first elastic member 21 from driving the first clamping portion 222 of the rotating member to be inserted into the slot 511 of the second matching structure 50.

[0159] Furthermore, the hook portion 722 has a fourth guide slope 7222 on one side relatively close to the second stacking member 40. When the unlocked state is formed, the fourth guide slope 7222 is used to guide the second stacking member 40 when it moves in the direction of separating from the first stacking member 10. In other words, the fourth guide slope 7222 can prevent the hook portion 722 and the bottom of the positioning member 81 from blocking each other, so that the second stacking member 40 can quickly move in the direction of separating from the first stacking member 10.

[0160] See also Figures 35 to 43 Furthermore, the present invention also provides a fourth embodiment. The inventive concept and most structures of the fourth embodiment are the same as those of the first embodiment, except that the first movable member 22 is rotatably connected to the first stacking member 10.

[0161] In the fourth embodiment, the first movable member 22 includes a rotating seat 224 and a first clamping portion 222 arranged on the rotating seat 224, the rotating seat 224 is rotatably connected to the first stacking member 10, and the second matching structure 50 includes a second clamping portion 51 arranged on the second stacking member 40, and the second clamping portion 51 is provided with a slot 511; in the locked state, the first clamping portion 222 can first rotate in the γ direction under the pressure of the second stacking member 40. At this time, the first elastic member 21 is elastically compressed by the pressure of the rotating seat 224. After the second stacking member 40 is stacked in place, the elastic restoring force of the first elastic member 21 causes the rotating seat 224 to rotate and reset in a direction close to the second clamping portion 51, thereby allowing the first clamping portion 222 to be inserted into the slot 511 to limit the second stacking member 40 from disengaging from the first stacking member 10 along the X direction, the Y direction and the Z direction.

[0162] See also Figure 39 to Figure 43Specifically, in this embodiment, the rotating seat 224 includes a clamping body 2242, a support body 2243 and a swivel support leg 2244, one end of the support body 2243 is connected to one side of the clamping body 2242, and the first clamping portion 222 is connected to one end of the clamping body 2242. One end of the clamping body 2242 relatively far from the first clamping portion 222 is an eaves body portion 22421, the eaves body portion 22421 and the first clamping portion 222 are respectively located on two sides of the support body 2243 that are relatively far away from each other, and the swivel support leg 2244 is connected to one end of the support body 2243 relatively far from the clamping body 2242, and the swivel support leg 2244 and the first clamping portion are located on the same side of the support body 2243.

[0163] A movable groove 11 is provided at the top of the first stacking member 10, and the movable groove 11 is used to install the first movable member 22. The movable groove 11 has a first slot 111 and a second slot 112 which are connected to each other. The first slot 111 is provided on the side wall of the first stacking member 10, and the second slot 112 is provided on the top wall of the first stacking member 10. The clamping body 2242 can rotate toward the side of the first slot 111 which is relatively away from the second slot 112 with the swivel support leg 2244 as the rotation point.

[0164] Further, the side wall of the movable groove 11 opposite to the first notch 111 is the first side wall 113, the two side walls opposite to the movable groove 11 are both the second side walls 114, and the bottom wall opposite to the second notch 112 is the first bottom wall 115. It can be understood that in this embodiment, the first elastic member 21 is clamped between the eaves body portion 22421 and the first stacking member 10, and the setting direction of the first elastic member 21 is toward the first bottom wall 115. In other words, the setting direction of the first elastic member 21 is perpendicular to the first bottom wall 115.

[0165] Furthermore, a foot slot 1131 is formed on the first side wall 113 , and a swivel foot 2244 of the swivel seat 224 is inserted into the foot slot 1131 . The swivel foot 2244 can be supported and rotated in the foot slot 1131 to ensure the rotation stability of the swivel seat 224 .

[0166] Please see again Figures 35 to 43 Furthermore, the first stacking member 10 is also provided with a seat body stopper 13, which is fixedly mounted on the first stacking member 10 and located between the rotating seat 224 and the first stacking member 10, and is used to limit the rotating seat 224 from being separated from the first stacking member 224. Specifically, the seat body stopper 13 is fixedly mounted on the first bottom wall 115 and located between the rotating seat 224 and the first bottom wall 115, and is used to limit the rotating seat 224 from moving in a direction away from the first side wall 113, that is, to limit the rotating seat 224 from being separated from the movable groove 11.

[0167] See also Fig.43, exemplarily, the seat body stopper 13 includes a base portion 131 fixedly connected to the first bottom wall 115 and a stopper portion 132 protruding from the base portion 131 on a side away from the first side wall 113, and the rotating seat 224 is rotatably disposed on the base portion 131 and located between the stopper portion 132 and the first side wall 113. In other words, the rotating seat 224 is limited by the stopper portion 132 and the leg slot 1131 when translated in the X direction.

[0168] Furthermore, the blocking body 132 is further provided with a receiving groove 1321, in which the first elastic member 21 is disposed. In order to ensure the stability of the first elastic member 21, a sleeve 1322 is further provided at the bottom of the receiving groove 1321, on which the first elastic member 21 is partially sleeved.

[0169] In this embodiment, the positioning assembly 80 is disposed on the second stacking member 40 . Under the action of an external force, the positioning assembly 80 can move to a positioning position so that the stacking system 100 can switch from a locked state to an unlocked state.

[0170] Specifically, the positioning assembly 80 includes a positioning member 81, which is rotatably connected to the second stacking member 40. The positioning member 81 has a first arm 814 and a second arm 815 with opposite rotation directions. The first arm 814 can rotate to a positioning position under the action of an external force, and drive the second arm 815 to act in the opposite direction on the first movable member 22, so that the first movable member 22 rotates out of the second matching structure 50, thereby switching the stacking system 100 from a locked state to an unlocked state.

[0171] The positioning assembly 80 also includes a fourth elastic member 83, which is arranged between the first arm 814 and the second stacking member 40 and elastically acts on the first arm 814; when the stacking system switches from a locked state to an unlocked state, the fourth elastic member 83 can be compressed by the first arm 814 and drive the positioning member 81 to reset after the second stacking member 40 is separated from the first stacking member 10.

[0172] Please see again Figures 35 to 38 In this embodiment, a rotational installation slot 42 is further provided at the bottom of the second stacking member 40, and the positioning member 81 is rotatably installed in the rotational installation slot 42. The rotational installation slot 42 has a third slot 421 and a fourth slot 422. The third slot 421 is provided in the side wall of the second stacking member 40, and the fourth slot 422 is provided in the bottom wall of the second stacking member 40. Among them, the side wall of the rotational installation slot 42 opposite to the third slot 421 is the third side wall 423, and the two side walls opposite to the rotational installation slot 42 are both the fourth side wall 424, and the bottom wall opposite to the fourth slot 422 is the second bottom wall (not shown).

[0173] The connection between the first arm 814 and the second arm 815 is hinged between the two fourth side walls 424 of the rotation installation slot 42, and the fourth elastic member 83 is disposed between the first arm 814 and the second bottom wall. In the locked state and the reset state, the second arm 815 is parallel to the third side wall 423, and there is a rotation gap (not shown) between the first arm 814 and the second bottom wall.

[0174] Further, in order to facilitate the positioning member 81 to drive the rotating seat 224 to rotate to form an unlocked state, in this embodiment, the first clamping portion 222 of the rotating seat 224 is further provided with an abutting groove 2222, and the end of the second arm 815 away from the first arm 814 is further provided with an abutting foot 8151, and when the second stacking member 40 and the first stacking member 10 are stacked to form a locked state, the abutting foot 8151 can be accommodated in the abutting groove 2222. When switching from the locked state to the unlocked state, the user bends the first arm 814 upward, that is, the first arm 814 is rotated toward the side of the second bottom wall (see the α direction in the figure), the fourth elastic member 83 is compressed, and the second arm 815 is rotated in the opposite direction (see the β direction in the figure), and the abutting foot 8151 of the second arm 815 will rotate along the β direction, and push the rotating seat 224 to rotate through the abutting groove 2222, so that the first clamping portion is disengaged from the slot 511 of the second stacking member 40. It should be noted that during this process, the user needs to continuously apply force to the first arm 814, so that the first arm 814 first rotates to the positioning position, and then maintains the positioning position until the second stacking member 40 is completely separated from the first stacking member 10. In the first embodiment, the second embodiment and the third embodiment, after the user pulls the first movable member 22 to drive the positioning assembly 80 to reach the positioning position, the positioning member 81 can be stopped against the positioning matching portion 70 under the action of the second elastic member. Therefore, after the positioning member 81 reaches the positioning position, the user can no longer apply force to the first movable member 22, but keep the positioning member 81 in the positioning position through the positioning matching portion 70 until the second stacking member 40 is moved away from the first stacking member 10. It should be noted that the "positioning position" refers to the position of the positioning member 81 when the first arm 814 rotates to abut against the second bottom wall.

[0175] Please see again Figure 39 to Figure 43Furthermore, in order to improve the rotation stability of the rotating seat 224, in this embodiment, the seat body stopper 13 is further provided with two side auxiliary walls 133 arranged opposite to each other, and the two side auxiliary walls 133 are convexly arranged on the side of the base portion 131 away from the first bottom wall 115. A connecting hole 1331 is provided on the side auxiliary wall 133, and arc-shaped grooves 22431 are respectively provided on the two opposite sides of the support body 2243. The first stacking member 10 also includes an auxiliary shaft (not shown), one end of which is connected to the connecting hole, and the other end of which can slide in the arc-shaped groove 22431. When the rotating seat 224 rotates along the γ direction with the rotating body support leg 2244 as a fulcrum, so that the first clamping portion 222 is separated from the slot 511, the auxiliary shaft can cooperate with the arc-shaped groove to assist the rotating seat 224 in rotating, so as to prevent the rotating seat 224 from shaking along the Y direction during the rotation process.

[0176] See also Fig.44 , further, the present invention also provides a fifth embodiment, the inventive concept and most of the structures of the fifth embodiment are the same as those of the first embodiment, the difference is that: in the fifth embodiment, the bottoms of the first stacking member 10 and the second stacking member 40 are both planes, the first matching structure 20 and the third matching structure 30 include two groups, one of which is arranged on both sides of the top of the first stacking member 10 in the X direction, and the other is arranged on both sides of the top of the first stacking member 10 in the Y direction; the second matching structure 50 and the fourth matching structure 60 include two groups, one of which is arranged on both sides of the bottom of the second stacking member in the X direction, and the other is arranged on both sides of the bottom of the second stacking member in the Y direction. In this way, the stacking and automatic locking between the first stacking member 10 and the second stacking member 40 can also be achieved in the X, Y, and Z directions by gravity and / or additional pressure.

[0177] In other words, when in use, it is still only necessary to place the second stacking member 40 directly on the first stacking member 10, and then the four first clamping parts 222 can be mutually clamped with the second clamping parts 51 at the corresponding positions by gravity, so that the stacking system 100 is in a locked state. When switching to the unlocked state, one set of the first matching structure 20 and the third matching structure 30 can be pulled first, and then another set of the first matching structure 20 and the third matching structure 30 can be pulled, so that the positioning members 81 on the four sides all reach the positioning position, and the second stacking member 40 can be moved away from the first stacking member 10.

[0178] Furthermore, the present invention also provides a sixth embodiment. The inventive concept and most of the structures of the sixth embodiment are the same as those of the first embodiment, except that: in the sixth embodiment, the first matching structure 20 and the third matching structure 30 are relatively arranged at two locations on the top of the first stacking member 10 along the X direction or the Y direction, and the second matching structure 50 and the fourth matching structure 60 are relatively arranged at two locations on the bottom of the second stacking member 40 along the X direction or the Y direction; but the structure of the third matching structure 30 may be different from that of the first matching structure 20; in this embodiment, the third matching structure 30 includes a first matching portion arranged at the top of the first stacking member 10, and the fourth matching structure 60 includes a second matching portion arranged at the bottom of the second stacking member 40, and when the second stacking member 40 is stacked on the first stacking member 10, the first matching portion can be mutually engaged with the second matching portion to cooperate with the first matching structure 20 and the second matching structure 50 to limit the movement of the first stacking member 10 and the second stacking member 40 along the X direction, the Y direction, and the Z direction.

[0179] It can be understood that the first matching portion and the second matching portion can be implemented as a clamping plate that can be clamped together, or can be implemented as a recessed hole and a protrusion that can be clamped together.

[0180] Optionally, in one embodiment, the first mating structure 20 and the third mating structure 30 are relatively arranged on both sides of the top of the first stack 10 along the X direction or the Y direction, and the second mating structure 50 and the fourth mating structure 60 are relatively arranged on both sides of the bottom of the second stack 40 along the X direction or the Y direction; the first mating portion and the second mating portion are implemented as card plates that can be clamped to each other.

[0181] It is understandable that in other embodiments, the clamping structure of the clamping plate can be changed to change the clamping direction accordingly, so that after the second matching portion is mutually clamped with the first matching portion, the movement of the second stacking member 40 can be restricted in the Z direction and the X direction or the Z direction and the Y direction.

[0182] It can be understood that the way in which the first matching portion and the second matching portion cooperate with each other can be combined with the first embodiment. In other words, in other embodiments, it is also possible to set the third matching structure 30 with the same structure as the first matching structure 20 to cooperate with the first matching structure 20, and also to set the third matching structure 30 with a different structure from the first matching structure 20 to cooperate with the first matching structure 20. As long as the movement of the second stacking member 40 along the X direction, the Y direction, and the Z direction can be restricted in the end.

[0183] See also Figures 45 to 50, the present invention also provides a seventh embodiment, the inventive concept and most of the structures of the seventh embodiment are the same as those of the first embodiment and the sixth embodiment, except that: in the seventh embodiment, the length of the first stacking member 10 is an integer multiple of the width of the second stacking member 40. Exemplarily, in this embodiment, the width of the first stacking member 10 is equal to the length of the second stacking member 40, and the length of the first stacking member 10 is twice the width of the second stacking member 40. In other words, in this embodiment, two second stacking members 40 can be stacked in parallel above each first stacking member 10. It can be understood that in other embodiments, one or more than three second stacking members 40 can be stacked above the first stacking member 10, and the length, width or size of the second stacking member 40 can be set according to requirements, as long as the stacking lock between the first stacking member 10 and the second stacking member 40 is not affected.

[0184] Compared with the related art, the multiple stacking members 1 of the stacking system 100 provided in the present application can be stacked and connected up and down, can be carried and moved at the same time, and can remain stable during the transportation and movement process, and are not easy to slip and separate. While saving transportation time, the storage space can also be better utilized when storing.

[0185] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0186] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
