In some embodiments, as shown in fig. 14, one end of the mounting cavity 1b in the length direction of the vehicle body roof 100 is opened to form an opening 1c, and the battery cell 21 is adapted to be mounted to the corresponding mounting cavity 1b through the opening 1c.

In the assembly process that the battery monomer 21 is installed in the installation cavity 1b, the uncovered 1c is aimed at to one end of battery monomer 21 to with battery monomer 21 follow the length direction of automobile body ceiling 100 and push gradually to installation cavity 1b, made things convenient for the installation of battery monomer 21, simultaneously, uncovered 1c provides great operating space, when battery monomer 21 needs to be changed or overhaul, if battery monomer 21 is nearer to uncovered 1c, can directly overhaul or change battery monomer 21 in uncovered 1c, if battery monomer 21 is farther to uncovered 1c, can draw battery monomer 21 to uncovered 1c or take out battery monomer 21 from uncovered 1c, in order to overhaul or change battery monomer 21, thereby simplified the change and overhaul process of battery monomer 21.

For example, in the example of fig. 14, the carrier 1 extends in the front-rear direction, and the rear end of the carrier 1 is opened to form an opening 1c; of course, the opening 1c may be formed at the front end of the carrier 1, or the front and rear ends of the carrier 1 may be formed with the openings 1c, respectively. The battery cell 21 may be mounted to the mounting cavity 1b through any one of the openings 1c.

It can be seen that one of both ends of the carrier 1 in the longitudinal direction of the vehicle body ceiling 100 (for example, the front-rear direction of the vehicle 200) is opened to form the opening 1c, or both ends of the carrier 1 in the longitudinal direction of the vehicle body ceiling 100 are respectively opened to form the openings 1c, respectively.

In some embodiments, as shown in fig. 1 and 11, the body ceiling 100 of the vehicle 200 further includes a cover plate 6, and a side of the installation cavity 1b facing the inside of the vehicle 200 and/or facing the outside of the vehicle 200 is formed with an installation opening 1d, that is, a side of the installation cavity 1b facing the inside of the vehicle 200 is opened to form the installation opening 1d, and/or a side of the installation cavity 1b facing the outside of the vehicle 200 is opened to form the installation opening 1d; the mounting opening 1d is configured to allow the battery cell 21 to pass through and be mounted in the mounting cavity 1b, the cover plate 6 is movably connected with the bearing piece 1 to open and close the mounting opening 1d, the cover plate 6 is covered on the mounting opening 1d to realize the sealing of the mounting cavity 1b, other foreign matters such as liquid or dust are prevented from entering the mounting cavity 1b to influence the normal operation of the battery cell 21, and the safety of the battery cell 21 is ensured.

For example, the cover plate 6 may be movably fitted with the carrier 1, or pivotally connected, or detachably connected or semi-permanently connected by fasteners (e.g., bolts, screws, rivets, etc.), or the like.

It is to be understood that when the mounting openings 1d are formed at the side of the mounting cavity 1b facing the inside of the vehicle 200 and the side facing the outside of the vehicle 200, respectively, the battery cell 21 may be mounted to the mounting cavity 1b through any one of the mounting openings 1d, at which time each mounting opening 1d corresponds to at least a portion of the cover plate 6, respectively. When the mounting port 1d is located on the side of the mounting cavity 1b facing the interior of the vehicle 200, the mounting of the battery cell 21 may be completed inside the vehicle 200; when the mounting port 1d is located on the side of the mounting cavity 1b facing the outside of the vehicle 200, the mounting of the battery cell 21 may be completed outside the vehicle 200.

In addition, each of the plurality of mounting cavities 1b is respectively formed with a mounting port 1d, the plurality of mounting ports 1d can be positioned on the same side or different sides of the plurality of mounting cavities 1b, and when the plurality of mounting ports 1d are positioned on the same side of the plurality of mounting cavities 1b, two adjacent mounting ports 1d can be communicated or separated; the plurality of mounting cavities 1b may have the same number of mounting ports 1d or different numbers.
