Referring to fig. 1, according to an aspect of the present invention, there is provided a battery pack case 1 including:

the bottom cover, the top cover 2 that sets up with the bottom relatively and four sides of connecting top cover 2 and bottom, top cover 2 part is inwards sunken to be formed with recess 3, is provided with quick change connector 4 in the recess 3.

Generally, the design of the quick-change battery is always larger than the size of the common power battery, and besides the structural change of the mounting plate, the quick-change connector 4 has the greatest influence on the size of the battery pack. The quick-change connector 4 is often mounted on an extension of the side of the battery or on the lid, which in any case leads to an increased space occupation of the battery. In the above embodiment, the top cover 2 of the battery pack case 1 is provided with the concave groove 3, so as to provide a space for installing the quick-change connector 4. In this way, the quick-change connector 4 is mounted in the groove 3, so that the volume occupied by the whole battery pack case 1 can be reduced compared with the prior art in which the quick-change connector 4 is directly arranged on the surface of the battery pack case 1. Particularly for small electric vehicles, because the small electric vehicles have small size and small ground clearance, the battery pack case 1 in the prior art is easy to cause the low ground clearance, which cannot meet the relevant standards. This embodiment has an advantage that the volume of the battery pack case 1 can be reduced.

Further, the number of the grooves 3 is two, and the two grooves 3 are oppositely arranged at the edge position of the top cover 2. The groove 3 and the quick-change connector 4 are arranged at the edge of the top cover 2, so that the external connector and the quick-change connector 4 can be conveniently inserted into each other during installation.

Further, the recess 3 comprises a bottom surface, side walls formed around the bottom surface, and an opening arranged opposite the bottom surface, the quick-change connector 4 being partly above the position of the opening. As a further embodiment of this embodiment, the quick-change connector 4 is arranged not higher than the opening position. Those skilled in the art can understand that the quick-change connector 4 can be partially disposed in the groove 3 to reduce the volume occupied by the battery pack case 1, and as an alternative embodiment, the quick-change connector 4 can be fully disposed in the groove 3, so that the volume occupied by the whole battery pack case 1 is not affected by the quick-change connector 4, and the volume of the battery pack case 1 can be minimized.

Further, a quick-change connector 4 is arranged at the bottom surface of the groove 3, and a socket of the quick-change connector 4 is arranged facing the opening. The opening of the quick-change connector 4 of the groove 3 is arranged facing the opening of the groove 3, so that the insertion is convenient, and the operation of an operator is easier.

Further, a quick-change connector 4 is arranged at the side of the groove 3, and a socket of the quick-change connector 4 is arranged facing the side wall. The arrangement of the interface facing the side wall can reduce the possibility of dust deposition of the interface and avoid poor contact caused by serious dust deposition in the long-term use process.

Furthermore, the box body is also provided with a mounting plate 5 all around, and the mounting plate 5 includes the base plate and sets up in the mounting hole 51 of base plate, and the base plate is connected with the box body. The mounting plate 5 is used for fixedly mounting the battery pack box body 1 on the electric automobile, and the battery pack box body 1 is prevented from shaking in the running process of the automobile. In particular, the mounting plate 5 may be connected to the vehicle housing by screws.

Furthermore, the top cover 2 is detachably connected with the side edge, so that when different quick-change batteries or quick-change connectors 4 need to be replaced, only the top cover 2 can be replaced without replacing the whole battery pack box body 1.

According to another aspect of the utility model, the utility model further provides a battery box assembly, which comprises the battery pack box body 1 and a battery, wherein the battery is placed in the battery pack box body 1. Since the battery box assembly includes all the technical solutions of all the battery pack boxes 1, at least all the beneficial effects brought by all the technical solutions are achieved, and are not described in detail herein.

According to another aspect of the utility model, the utility model also provides an electric automobile which comprises the battery box assembly. Since the electric vehicle includes all the technical solutions of all the battery box assemblies, at least all the beneficial effects brought by all the technical solutions are achieved, and are not described in detail herein.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents made by the claims and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
