A rotating plate 306 is movably installed inside the outer groove 302 of the plug rod, and a second rotating shaft 307 is fixedly installed at both ends of the rotating plate 306. The second rotating shaft 307 is rotatably connected to the inner wall of the outer groove 302 of the plug rod. One end of the special-shaped rod 303 is movably inserted into the inner wall of the outer groove 302 of the plug rod, and the other end of the special-shaped rod 303 is movably inserted into the surface of the plug rod 203 and is flush with the surface of the plug rod 203.

[0038] The limiting mechanism 3 also includes a limiting groove 304, an arc-shaped groove 308 and a limiting buckle 309. The outer surface of the special-shaped rod 303 that is inserted into the outer groove 302 of the insertion rod is provided with a limiting groove 304, the inner surface of the rotating plate 306 is provided with an arc-shaped groove 308, and the inner part of the arc-shaped groove 308 is fixedly installed with a limiting buckle 309.

[0039] By cooperating with the plug-in rod 203 and the plug-in inner groove 206, each first L-shaped bracket 201 and the second L-shaped bracket 202 can be combined and fixed to each other by inserting the plug-in rod 203 into the plug-in inner groove 206, thereby avoiding the first L-shaped bracket 201 or the second L-shaped bracket 202 from being loose. Moreover, by setting the limiting mechanism 3, when it is necessary to remove the bracket structure 2, the staff can insert their fingers into the plug-in side groove 207 at the plug-in side groove 207 position on the outside of any bracket structure 2 to press one end of the special-shaped rod 303, so that the special-shaped rod 303 is pushed toward the inside of the special-shaped groove 301, thereby causing the other end of the special-shaped rod 303 to rotate outward, and then rotate inside the arc-shaped slot 308, at which time the limiting buckle 309 will be released from the inner part of the limiting slot 304. The second rotating shaft 307 is subjected to the elastic force of the torsion spring and drives the rotating plate 306 to rotate out of the outer groove 302 of the plug rod, thereby causing the rotating plate 306 to rotate out and insert into the inside of the plug-in side groove 207. At this time, the staff can push the rotating plate 306 in the direction of the shrinking side groove 205 to make the rotating plate 306 drive the plug-in rod 203 to retract into the inside of the shrinking inner groove 208 until the plug-in rod 203 is completely removed from the plug-in inner groove 206. At this time, the first fixed block 204 or the second fixed block 211 connected thereto can be directly pulled outward, thereby releasing the connection between the first L-shaped bracket 201 and the second L-shaped bracket 202, and then the other first L-shaped bracket 201 or the second L-shaped bracket 202 connected thereto can be pulled outward to realize the removal of the bracket structure 2.

[0040] The shrinkage side grooves 205 and the plugging side grooves 207 on the surfaces of the adjacent first L-shaped brackets 201 and second L-shaped brackets 202 are interconnected, and the width dimension between the inner walls of the shrinkage side grooves 205 and the plugging side grooves 207 is consistent with the width dimension of the rotating plate 306 .

[0041] The side panels of the carriage are all connected with locking mechanisms, and the bottom end of the front panel of the carriage is rigidly connected to the top end of the bottom panel of the carriage.

[0042] The angle between the special-shaped rod 303 and the inner wall of the special-shaped groove 301 is ten degrees. The surface of the limiting buckle 309 is provided with an arc surface, and the surface of the limiting groove 304 is provided with an arc surface.

[0043] When the combined rear compartment support structure for an electric three-wheeled motorcycle is used, a plurality of combined mechanisms 1 can be spliced ​​and combined to form a compartment floor, so that the device can assemble a suitable number of combined mechanisms 1 according to the size of the rear frame 6, thereby matching the area of ​​the compartment floor with the rear frames 6 of different sizes, which is convenient for use on electric three-wheeled motorcycles of different models. Moreover, a plurality of combined mechanisms 1 are spliced ​​and combined to form compartment side panels and a compartment front panel, so that the device can assemble different numbers of combined mechanisms 1 according to the required compartment height, thereby facilitating the device to be combined into compartments of different heights. At the same time, when assembling the compartment side panels and the compartment front panel, the position where the L-shaped combined rod 102 of each combined mechanism 1 is connected can be fixed by bolts, so as to avoid the situation where the height of the plurality of combined mechanisms 1 is too high and unstable after being spliced.

[0044] After the assembly mechanism 1 is installed, the bracket structure 2 can be installed on the outermost side of the assembled assembly mechanism 1, so that the first L-shaped bracket 201 and the second L-shaped bracket 202 are arranged in sequence on the outer side of the assembly board 101, so that the outer frame position of the assembly board 101 is assembled and fixed by the bracket structure 2, so as to avoid the assembled assembly boards 101 being loose to each other, and the outer surface of the outermost assembly board 101 can be kept flat, so as to facilitate its subsequent installation;

[0045] When connecting the first L-shaped bracket 201 and the second L-shaped bracket 202, each first L-shaped bracket 201 and the second L-shaped bracket 202 can be combined and fixed to each other by inserting the plug-in rod 203 into the plug-in inner groove 206, so as to avoid the first L-shaped bracket 201 or the second L-shaped bracket 202 being loose;

[0046] When it is necessary to dismantle the support structure 2, the staff can insert their fingers into the plug-in side groove 207 at the position of the plug-in side groove 207 on the outside of any one of the support structures 2, and press one end of the special-shaped rod 303 to push the special-shaped rod 303 toward the inside of the special-shaped groove 301, so that the other end of the special-shaped rod 303 rotates outward, and then rotates inside the arc-shaped slot 308. At this time, the limit buckle 309 will rotate out from the inside of the limit slot 304. At this time, the second rotating shaft 307 will be subjected to the elastic force of the torsion spring to drive the rotating plate 306 to rotate out of the outer groove 302 of the plug rod, so that the rotating plate 306 rotates out and snaps into the plug rod. The inside of the side groove 207, at this time, the staff can push the rotating plate 306 in the direction of the shrinking side groove 205, so that the rotating plate 306 drives the plug-in rod 203 to retract into the inside of the shrinking inner groove 208, until the plug-in rod 203 is completely removed from the plug-in inner groove 206, at this time, the first fixed block 204 or the second fixed block 211 connected thereto can be directly pulled outwards, thereby releasing the connection between the first L-shaped bracket 201 and the second L-shaped bracket 202, and then the other first L-shaped bracket 201 or the second L-shaped bracket 202 connected thereto can be pulled outwards, thereby realizing the removal of the bracket structure 2;

[0047] The surfaces of the installed car side panels, car front panels and car bottom panels will leave multiple square through holes due to the square grooves 104, so that when the car is installed into a U-shaped three-dimensional structure, the square grooves 104 can maintain air circulation in the car and avoid water accumulation in the car due to rainy days.

[0048] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
