The charging cabinet maintenance passage 114 facing the charging cabinet 15 is provided on the battery exchange box 13, so that the maintenance personnel can perform maintenance operations on the charging cabinet 15 without going deep into the battery exchange room 1, so that there is no need to set up a special passage for maintenance personnel to walk inside the battery exchange room 1, so that the internal structure of the battery exchange room 1 is more compact, the utilization rate of the internal space of the battery exchange room 1 is improved, and the floor area of ​​the battery exchange room 1 is reduced, thereby reducing the floor area of ​​the battery exchange station and reducing the construction cost.

[0117] In other alternative embodiments, only the control cabinet maintenance channel 113 or only the charging cabinet maintenance channel 114 may be set separately. In this state, the battery exchange room 1 can be entered through the control cabinet maintenance channel 113 to inspect the charging cabinet 15, or the battery exchange room 1 can be entered through the charging cabinet maintenance channel 114 to inspect the control cabinet 14.

[0118] In this embodiment, if Figure 4 As shown, the control cabinet 14 and the battery transfer device 17 are spaced apart in the direction of vehicle travel, and the control cabinet 14 and the charging cabinet 15 are spaced apart perpendicular to the direction of vehicle travel, and the two spaces are interconnected to form an L-shaped channel. The distance of the charging cabinet maintenance channel 114 perpendicular to the direction of vehicle travel is greater than the distance of the charging cabinet 15 perpendicular to the direction of vehicle travel, that is, part of the charging cabinet maintenance channel 114 is arranged at the L-shaped channel, and the staff can enter the interior of the battery exchange room 1 through the charging cabinet maintenance channel 114 to inspect the internal structure of the battery exchange room 1 (such as the charger, control cabinet 14, transfer device 17, etc.). In other alternative embodiments, the control panel of the control cabinet 14 can face the interior of the battery exchange room 1, and the staff can directly enter the interior of the battery exchange room 1 through the charging cabinet maintenance channel 114 to inspect the control cabinet 14.

[0119] like Figure 2 and Figure 4 As shown, the battery transport device maintenance passage 115 and the battery transport device 17 are correspondingly arranged, and the battery transport device maintenance passage 115 is arranged on one side of the battery transport device 17 in the direction of vehicle travel. It should be noted that the battery transport device maintenance passage 115 and the battery transport device 17 are correspondingly arranged here, which means that when the battery transport device maintenance passage 115 is opened, the battery transport device 17 is just exposed, and the maintenance personnel can even perform maintenance on the battery transport device 17 outside the battery exchange room 1. The battery transport device maintenance passage 115 facing the battery transport device 17 is arranged on the battery exchange box 13, so that the maintenance personnel can perform maintenance operations on the battery transport device 17 without going deep into the interior of the battery exchange room 1, so that there is no need to set up a passage inside the battery exchange room 1 specifically for maintenance personnel to walk, so that the internal structure of the battery exchange room 1 is more compact, the utilization rate of the internal space of the battery exchange room 1 is improved, and the floor area of ​​the battery exchange room 1 is reduced, thereby reducing the floor area of ​​the battery exchange station and reducing the construction cost.

[0120] like Figure 4 As shown, the battery transport device maintenance channel 115 and the charging cabinet maintenance channel 114 are located on different sides of the battery exchange box 13, that is, the battery transport device maintenance channel 115 and the charging cabinet maintenance channel 114 are respectively arranged on both sides of the battery exchange box 13 in the driving direction of the vehicle to avoid the charging cabinet 15 from blocking the battery transport device 17, so that maintenance personnel can inspect the battery transport device through the battery transport device maintenance channel 115.

[0121] like Figure 2 and Figure 4As shown, the counterweight inspection channel 116 and the counterweight 18 are provided in correspondence, and the counterweight inspection channel 116 is provided on the side of the counterweight 18 away from the charging rack 16 along the direction of vehicle travel. It should be noted that the counterweight inspection channel 116 and the counterweight 18 are provided in correspondence here, which means that when the counterweight inspection channel 116 is opened, the counterweight 18 is just exposed, and the maintenance personnel can even inspect the counterweight 18 outside the power exchange room 1. The counterweight inspection channel 116 facing the counterweight 18 is provided on the power exchange box 13, so that the maintenance personnel can perform the inspection operation on the counterweight 18 without going deep into the interior of the power exchange room 1, so that there is no need to set up a special passage for maintenance personnel to walk inside the power exchange room 1, so that the internal structure of the power exchange room 1 is more compact, the utilization rate of the internal space of the power exchange room 1 is improved, and the floor area of ​​the power exchange room 1 is reduced, thereby reducing the floor area of ​​the power exchange station and reducing the construction cost.

[0122] In this embodiment, if Figure 4 As shown, the control cabinet maintenance channel 113 and the charging cabinet maintenance channel 114 are arranged on the same side of the battery swap room 1 in the direction of vehicle travel, the battery transfer device maintenance channel 115 and the counterweight block maintenance channel 116 can be arranged on the same side of the battery swap room 1 in the direction of vehicle travel, and the control cabinet maintenance channel 113 and the battery transfer device maintenance channel 115 are arranged on different sides of the battery swap room 1 in the direction of vehicle travel, so that each maintenance channel will not interfere with each other, and maintenance personnel can inspect the corresponding structure through the corresponding maintenance channel.

[0123] Furthermore, if Figure 4 As shown, since the counterweight 18 and the battery transport device 17 are staggered, the counterweight 18 and the battery transport device 17 will not block each other, so the battery transport device inspection channel 115 and the counterweight inspection channel 116 in this embodiment can be set on the same side of the battery exchange room 1 in the direction of vehicle travel, which is convenient for maintenance personnel to inspect the battery transport device 17 and the counterweight 18. Moreover, the counterweight 18 and the battery transport device 17 are staggered, which allows maintenance personnel to inspect the battery transport device 17 without worrying about safety issues such as the counterweight falling, thereby improving the safety of maintenance personnel when inspecting through the battery transport device inspection channel 115.

[0124] like Figure 4As shown, the hydraulic station maintenance passage 117 is provided in correspondence with the hydraulic station 19, and the hydraulic station maintenance passage 117 is provided on the side of the hydraulic station 19 facing the outside of the battery exchange box 13. It should be noted that the hydraulic station maintenance passage 117 and the hydraulic station 19 are provided in correspondence here, which means that when the hydraulic station maintenance passage 117 is opened, the hydraulic station 19 is just exposed, and the maintenance personnel can even perform maintenance on the hydraulic station 19 outside the battery exchange room 1. The hydraulic station maintenance passage 117 facing the hydraulic station 19 is provided on the battery exchange box 13, so that the maintenance personnel can perform maintenance operations on the hydraulic station 19 without going deep into the interior of the battery exchange room 1, thereby eliminating the need to provide a special passage for maintenance personnel to walk inside the battery exchange room 1, making the internal structure of the battery exchange room 1 more compact, improving the utilization rate of the internal space of the battery exchange room 1, and reducing the floor area of ​​the battery exchange room 1, thereby reducing the floor area of ​​the battery exchange station and reducing the cost of station construction.

[0125] like Figure 4 As shown, the hydraulic station 19 and the control cabinet 14 are located on the same side of the battery exchange box 13, specifically, the hydraulic station 19 and the control cabinet 14 are located on the same side of the battery exchange box 13 along the vehicle driving direction, and are respectively located on both sides of the charging cabinet 15 perpendicular to the vehicle driving direction. The control cabinet 14 and the hydraulic station 19 jointly occupy the space on only one side of the battery exchange box 13, making the internal structure of the battery exchange room 1 more compact, improving the utilization rate of the internal space of the battery exchange room 1, reducing the floor space of the battery exchange room 1, and thus reducing the floor space of the battery exchange station and reducing the construction cost.

[0126] like Figure 2-Figure 4 As shown, the control cabinet maintenance channel 113, the charging cabinet maintenance channel 114, the battery transport device maintenance channel 115, the counterweight block maintenance channel 116, and the hydraulic station maintenance channel 117 are covered by an openable maintenance door 119 and / or a maintenance cover plate 120 detachably connected to the battery exchange box 13. In this embodiment, the openings of the above-mentioned maintenance channels are blocked by an openable maintenance door 119 and / or a detachable maintenance cover plate 120, so that foreign objects can be prevented from entering the interior of the battery exchange room 1 in a non-maintenance state, thereby protecting the battery exchange room 1. In a maintenance state, it is convenient for maintenance personnel to open the channel openings of the maintenance channels and facilitate maintenance operations of maintenance personnel.

[0127] Specifically, the charging cabinet maintenance channel 114, the battery transfer device maintenance channel 115, and the counterweight block maintenance channel 116 in this embodiment are covered by an inspection door 119, and the control cabinet maintenance channel 113 and the hydraulic station maintenance channel 117 are covered by an inspection cover plate 120 that is detachably connected to the battery exchange box 13.

[0128] In other alternative embodiments, whether the inspection passage is covered by an openable inspection door 119 or by a detachably connected inspection cover plate 120 can be designed according to actual needs.

[0129] Furthermore, in this embodiment, the battery exchange box 13 integrates the control cabinet 14 and the column 121, and the column 121 is used to install the charging rack 16 and / or the battery transfer device 17, so that the control cabinet 14 and the column 121 can be pre-integrated in the battery exchange room 1, and then the battery exchange room 1 can be transported to the site as a whole, thereby shortening the station construction cycle, reducing the station construction cost, and meeting the needs of rapid batch construction in a short period of time.

[0130] In other alternative embodiments, the control cabinet 14 and / or the column 121 may be independently transported to the site and then installed in the power exchange room 1, or the power exchange box 13 may only integrate the control cabinet 14 or the column 121 in advance, and the other structure may be independently transported to the site and then installed in the power exchange room 1.

[0131] like Figure 1 and Figure 2 As shown, the battery exchange box 13 in this embodiment is placed vertically. Compared with the traditional horizontal placement of the container-type battery exchange room, the vertically placed battery exchange box 13 occupies a relatively smaller area, saving land resources and reducing the cost of station construction. Among them, the vertical placement of the battery exchange box 13 specifically means that after the battery exchange box 13 is placed, the length and width of the battery exchange box 13 in the horizontal direction are smaller than the height of the battery exchange box 13 in the vehicle height direction, thereby reducing the footprint of the battery exchange box 13.

[0132] The battery exchange box 13 in this embodiment is an integral structure. In other alternative embodiments, the battery exchange room 1 also includes multiple battery exchange boxes 13, and multiple battery exchange boxes 13 are stacked in sequence along the height direction of the vehicle, so that the volume of the battery exchange room 1 can be adjusted according to actual needs to accommodate different numbers of battery packs. The above-mentioned arrangement can also reduce the height dimension of a single battery exchange box 13 and reduce the manufacturing cost of the battery exchange box 13. In this state, a charging rack 16 is provided in any battery exchange box 13, and the charging racks 16 in multiple battery exchange boxes 13 are interconnected to ensure the stability of the battery transport device 17 during operation. The battery transport device 17 can transport battery packs in multiple battery exchange boxes 13, so that the battery packs of all charging racks 16 and battery exchange equipment 4 in the battery exchange room 1 can be transported through one battery transport device 17, reducing the number of battery transport devices 17 and reducing costs. A battery transport device inspection channel 115 is provided on any battery exchange box 13 to facilitate the inspection of each height position of the battery transport device 17.

[0133] Furthermore, the counterweight inspection channel 116 is provided on the lower battery exchange box 13. Specifically, when the battery exchange box 13 is an integral structure, the counterweight inspection channel 116 can be opened only at the lower part of the battery exchange box 13; when the battery exchange room 1 includes multiple battery exchange boxes 13, the counterweight inspection channel 116 can be opened on the battery exchange box 13 located at the lowest part of the battery exchange room 1. Thus, the maintenance personnel can perform maintenance operations on the counterweight 18 at the lower position of the battery exchange box 13, prevent safety problems such as the counterweight 18 falling, and improve the safety of the maintenance of the counterweight 18.
