[0032] The module connecting structure of the utility model comprises a first connecting part 3 and a second connecting part 4, and the first connecting part 3 is at least partially arranged on the first module 1, and the second connecting part 4 is at least partially arranged on the second module 2. The first connecting part 3 and the second connecting part 4 are provided with a positioning structure, and the positioning structure is used for positioning the first connecting part 3 and the second connecting part 4; the first connecting part 3 comprises a locking surface 31, and the locking surface 31 is provided with a limiting part 32; the second connecting part 4 comprises a fixed part 41 and a sliding part 42, the sliding part 42 can slide relative to the fixed part 41, one of the sliding part 42 and the locking surface 31 is provided with an elastic locking piece, and the other is provided with a locking groove 422, the elastic locking piece has a movable end, when the first connecting part 3 is positioned on the second connecting part 4 through the positioning structure, and the movable end of the elastic locking piece is embedded in the locking groove 422, the sliding part 42 and the fixed part 41 are cooperated to clamp the limiting part 32.

[0033] The direction of the first connecting part 3 close to or away from the second connecting part 4 is defined as the first direction. In the assembling process of the first module 1 and the second module 2, the first connecting part 3 is first pressed against the second connecting part 4 along the first direction, at this time, the first connecting part 3 and the second connecting part 4 are positioned by the positioning structure, then the sliding part 42 is slid along the direction close to the fixed part 41, and when the movable end of the elastic locking piece is embedded in the locking groove 422, the sliding part 42 is locked; at this time, the sliding part 42 cooperates with the fixed part 41 to clamp the limiting part 32, so that the limiting part 32 can be fixed by the clamping action of the sliding part 42 and the fixed part 41, thereby completing the assembly between the first module 1 and the second module 2. If the first module 1 and the second module 2 need to be disassembled, by making the movable end of the elastic locking piece away from the locking groove 422, the locking of the sliding part 42 can be released, then the sliding part 42 is slid along the direction away from the fixed part 41, the clamping force on the limiting part 32 can be removed, and the limiting part 32 can be removed from the second connecting part, thereby completing the disassembly between the first module 1 and the second module 2. Thus, the module connecting structure provided by the utility model realizes more efficient and convenient assembly and disassembly between modules by adopting the first connecting part 3 and the second connecting part 4, and by reasonably arranging the first connecting part 3 and the second connecting part 4, thereby improving the disassembly efficiency between modules.

[0034] The position of the sliding part 42 located in the position capable of cooperating with the fixed part 41 to clamp the limiting part 32 is defined as the plug-in position, and the position of the sliding part 42 located on the sliding track and having a distance greater than the distance between the plug-in position and the fixed part 41 is defined as the away position. Specifically, the sliding part 42 can change between the away position and the plug-in position relative to the fixed part 41; when the first connecting part 3 is pressed against the second connecting part 4, and the sliding part 42 is slid along the direction close to the fixed part 41 to the plug-in position, the movable end of the elastic locking piece is embedded in the locking groove 422, and the sliding part 42 cooperates with the fixed part 41 to clamp the limiting part 32. That is, the elastic locking piece and the locking groove 422 play a locking function when the limiting part 32 is clamped by the sliding part 42 and the fixed part 41, and the operator does not need to take other operations to lock the first connecting part 3 and the second connecting part 4, thereby simplifying the installation and locking steps, and being beneficial to improve the efficiency of assembling and disassembling modules.

[0035] Therefore, the assembly of the first module 1 and the second module 2 only needs two steps: the first step is to press the first connecting part 3 against the second connecting part 4, and the second step is to slide the sliding part 42 along the direction close to the fixed part 41 to the plug-in position, and the elastic locking piece cooperates with the locking groove 422 to lock. When disassembling the first module 1 and the second module 2, only the sliding part 42 is pushed away from the plug-in position, the locking of the elastic locking piece and the locking groove 422 and the clamping of the limiting part 32 can be released, and the disassembly between the first module 1 and the second module 2 is completed.
