[0052] In the above embodiment, at least one code scanning area 216 is provided on the charging plug-in device 212, so that the user can upload the information to be charged to the control system by scanning the identification code on the code scanning area 216 using a mobile terminal, so that the mobile charging device 3 is moved to the corresponding charging plug-in device 212 position for plugging and connecting. In addition, the code scanning area 216 is located at one end of the charging plug-in device 212 away from the cooling docking connector 213, so that the code scanning area 216 faces the side of the standard parking space 4, so that the user can scan the identification code on the code scanning area 216 more quickly and conveniently without manually entering information, saving time and energy, making the charging process simpler and more convenient, and improving the user experience.

[0053] Reference Figure 1-Figure 2 In one embodiment, a plurality of tie rods 22 are provided on the guide rail 20 , and the plurality of tie rods 22 are distributed at intervals on the guide rail 20 , and the guide rail 20 is connected to an external structure through the tie rods 22 .

[0054] In the above embodiment, a plurality of tie rods 22 of the same size are arranged on the guide rail 20 by welding, and the tie rods 22 are vertically arranged at the end of the guide rail 20 away from the standard parking space 4, so that the guide rail 20 can be fixedly connected to the top of the wall of the parking lot through the tie rods 22. In addition, a plurality of tie rods 22 are evenly distributed on the guide rail 20 at the same interval and fixedly connected to the top of the wall, ensuring that the distances between the tie rods 22 on the guide rail 20 are equal, thereby maintaining the stability and balance of the overall structure of the guide rail 20, and helping to avoid deformation or damage of the tie rods 22 or the guide rail 20 due to concentrated force.

[0055] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
