In a second combined state, the multilayer structure is at least provided with two layers, each layer is provided with one module 1, and at the moment, at least two connecting pieces 2 are respectively connected with the modules 1 positioned on different layers.

Exemplarily, as shown in fig. 1 and fig. 2, which illustrate a case where the connecting member 2 is a limiting plate, as shown in fig. 1, in a first combination state, four modules 1 are sequentially distributed, and adjacent modules 1 are all connected by the connecting member 2, and three connecting members 2 from left to right may be sequentially referred to as a first connecting member 21, a second connecting member 22, and a third connecting member 23. The four modules 1 from left to right can be sequentially referred to as a first module 11, a second module 12, a third module 13, and a fourth module 14, at this time, one of the two connecting portions 211 connected by the second connecting member 22 located on the second module 12 is a first connecting portion, one located on the third module 13 is a second connecting portion, and a distance between the first connecting portion and the second connecting portion is a first distance L1.
The connection relationship between the second connection member 22 and the second connection portion of the third module 13 is released and the third module 13 and the fourth module 14 are placed above the first module 11 and the second module 12 while keeping the state in which the first connection member 21 is connected to the first module 11 and the second module 12, and the state in which the third connection member 23 is connected to the third module 13 and the fourth module 14, respectively. Illustratively, the third module 13 is located above the first module 11, and the fourth module 14 is located above the second module 12, at least one of the connection portions 211 in the third module 13 and the fourth module 14 is a third connection portion, the distance from the third connection portion to the first connection portion is a second distance L2, and the second distance L2 is equal to the first distance L1, so that the second connection member 22 can be connected to the first connection portion and the third connection portion, respectively, thereby achieving relative position locking of modules 1 of different layers in the first direction.
Thus, when necessary, the connecting member 2 in the first combination state is used for connecting the interfaces (e.g., the limiting holes described above) of the two connecting portions 211, and in the second combination state, the connecting member 2 can be directly used for connecting the connecting portions 211 of different modules 1 in the first direction, without adding other interfaces (e.g., the limiting holes described above) to the connecting member 2, so that the structure is simple, and the practicability is high.
Under the second combination state, the connecting line of the first connecting part and the third connecting part extends along the first direction or forms an included angle relative to the first direction.

Taking the connecting portion 211 as a limiting column as an example, the third distance L3 is a distance from an axis of the limiting column to an end face of the module 1 along the X-axis direction. Illustratively, the connection portion is located on the center plane of the module 1 in the Z-axis direction, and will not be described in detail here.

In some cases, the connecting element 2 may also be embedded inside the module 1, improving the stability of the adjacent modules against forces in the first direction, which will not be described in detail here.
As shown in fig. 3 and 4, in the above embodiment, the backing plate may further include a plug connection structure, the plug connection structure includes a slot (not shown) and a plug 3, which are plugged into each other, and in the first combination state and the second combination state, any adjacent module 1 (which is distributed along a direction perpendicular to the first direction (for example, the second direction) is respectively provided with the slot and the plug 3.
In this way, relative movements of adjacent modules 1 (distributed in a direction perpendicular to the first direction), for example, in the first direction, can be limited by the plug connection structure, which can improve the stability of the connection of the modules 1 to a certain extent and can also reduce the structural limitation of the locking connection mechanism to a certain extent.
As shown in fig. 5, for example, in the first combination state, any adjacent modules 1 are connected by the plug connection structure, and the modules 1 are connected by the connecting member 2. Under the second composite state, all set up a plurality of modules 1 that distribute in proper order along the second direction in each layer of multilayer structure, each module 1 in at least one layer of multilayer structure is connected through connecting piece 2, and arbitrary adjacent module 1 of the same layer passes through the plug connection structural connection, and the module 1 that is located second direction both ends at least in the same layer passes through connecting piece 2 to be connected with the module 1 that is located other layers. In this case, the modules 1 of the second layer or the third layer can be connected only by the plug connection structure, so that the structure can be simplified to some extent, for example, the requirement for the number of connectors 2 is reduced, and will not be described in detail herein.
At this time, the plugging direction of the socket and the plug 3 coincides with the distribution direction (e.g., the second direction) of the modules 1.
The two ends of the module 1 (along the distribution direction of the module 1 in the first plane) are respectively provided with a slot and an insertion block 3.
As shown in fig. 1, in the first combination state, the slots of the modules 1 are located in the opposite direction of the X axis, and the insertion blocks 3 of the modules 1 are located in the positive direction of the X axis. In this case, the modules 1 have high structural consistency, which is beneficial to reducing the types of materials.
In other embodiments, the first module 11 and the third module 13 may have slots at both ends along the X-axis direction, and the second module 12 and the fourth module 14 may have insertion blocks 3 at both ends along the X-axis direction. In this case, four modules 1 may be combined to form the second combined state shown in fig. 2, but this case may require at least two types of modules 1, i.e., a module 1 having slots at both ends in the X-axis direction and a module 1 having insertion blocks 3 at both ends in the X-axis direction.
Further, in any direction (e.g., the second direction) perpendicular to the plugging direction of the socket, the inner walls of the socket are disposed close to the edge of the module 1.
It should be noted that the distance between the inner wall of the slot and the edge of the module 1 is determined according to the specific structural rigidity requirement, for example, taking the inner wall of the slot in the third direction as an example, the distance between the inner wall and the edge of the module 1 (i.e. the end wall in the third direction) is 10-30 cm.
So, the inner wall of slot all is close to the edge setting of module 1, can increase the cross-sectional area of grafting connection structure in the plane of perpendicular to grafting direction, strengthens the connection stability of adjacent module 1 in this plane, and the reliability is high.
Furthermore, the inner wall of the slot is provided with a convex block, the insertion block 3 is provided with a groove 31 corresponding to the convex block, and the convex block is in insertion fit with the corresponding groove 31.
Illustratively, the extending direction of the bump is the same as the second direction, the bump is disposed on the inner wall of the groove 31 along the third direction (i.e. the Z-axis direction), and the bump may be one or more.
So, set up lug and recess 31, can increase slot and 3 plug connection's of inserted block area of contact, reinforcing force stability can also strengthen the structural rigidity of slot in lug department to a certain extent.
