[0002] With the rapid development of the electric vehicle industry, the construction of charging infrastructure has become one of the key factors in promoting the popularization of electric vehicles. Although traditional single-layer charging piles have met the charging needs of electric vehicles to a certain extent, they still have many shortcomings in space utilization, charging efficiency and user experience. Therefore, a double-layer charging pile is needed to meet the needs.

[0003] Among existing double-deck charging systems, patent application CN214006693U discloses a double-deck parking garage with charging stations. The parking platform includes a parking platform, an alignment structure, and a protective structure. Gears connect the first columns on both sides of the parking platform, and the bottoms of the first columns are fixed with base plates. The buffer plates and fixed plates work together to ensure vehicles are more accurately parked on the parking platform while preventing damage from collisions. The sliders and rain shields work together to ensure more stable movement of the parking platform.

[0004] However, during the use of this equipment, it was found that when there were vehicles on the lower parking platform, vehicles on the upper platform could not leave, which increased the limitations of its use and reduced its convenience.

[0044] In this embodiment, when the second carrier 105 needs to be moved downward, the moving block 206 is driven by the walking device to slide horizontally on the first guide rail 201, so that the moving block 206 moves into one of the second guide rails 202. At this time, the second guide rail 202 and the moving block 206 are fixed by the positioning device, thereby improving the positioning effect of the moving block 206. Then, the lifting device drives the support block 203 to move downward, so that the support block 203 drives the two sets of second guide rails 202 to move downward, so that the second guide rails 202 drive the moving block 206 to move downward.

The air is compressed, so that the second cylinder 307 compresses the air in the first cylinder 301 through the connecting pipe 306. When the positioning groove of the moving block 206 moves to above the first insertion rod 304, the compressed air in the first cylinder 301 provides a driving force to the first piston 303, so that the first piston 303 drives the first insertion rod 304 to move and extend into the positioning groove of the moving block 206, thereby fixing the moving block 206 and the second guide rail 202, improving the fixing effect of the moving block 206 when the second guide rail 202 is raised and lowered, and improving the safety of use. When the moving block 206 needs to be moved up and down, the second guide rail 202 can be fixed to the second guide rail 202. When moving out of the second guide rail 202, the valve 308 is opened and the first piston 303 is pulled back to its original position by the tension spring 305, so that the excess air in the first cylinder 301 is discharged through the valve 308. After the first piston 303 is reset, it drives the first insertion rod 304 to separate from the moving block 206, thereby facilitating the movement of the moving block 206. When the moving block 206 is moved out of the second guide rail 202, the second piston 309 is pushed to move and reset by the spring 311, so that the end of the second insertion rod 310 is re-extended into the second guide rail 202, thereby improving the convenience of automatic locking of the moving block 206.
