Also, like parts are designated by like reference numerals throughout the drawings. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Fig. 1 schematically shows an axial side structural view of a battery carrier assembly of the present embodiment; as shown in the figure, the battery bracket assembly comprises three parts, namely a main supporting bracket body 3, an auxiliary supporting bracket body 1 and a frame connector 2, wherein the main supporting bracket body 3 is formed by welding longitudinal beams and cross beams in a splicing manner and is mainly used for placing a battery pack, the auxiliary supporting bracket body 1 is welded at the front end of the main supporting bracket body 3 and is mainly used as a mounting bracket of a high-voltage box and a low-voltage control box, the frame connector 2 comprises a plurality of connecting plates which are respectively connected to the outer sides of the longitudinal beams at two sides of the main supporting bracket body 3 and is mainly used for connecting the main supporting bracket body 3 with a frame, and the main supporting bracket body 3, the auxiliary supporting bracket body 1 and the frame connector 2 form the battery bracket assembly together; wherein, adopt the mode installation of spiro union between the frame connector 2 and the main support frame body 3, this kind of detachable construction has the convenience to the dismantlement of trading electric in-process battery package. The auxiliary supporting frame body 1 is fixedly connected with the rear part of the front end of the main supporting frame body 3 in a welding mode.

Fig. 2 schematically shows an installation three-dimensional structural view of the main support frame body 3 of the present embodiment. As shown in the figures, the main support frame body 3 of the present embodiment is mainly a support base plate formed by a planar frame, the planar frame is formed by two side longitudinal beams 31 and four cross beams 32 welded between the two side longitudinal beams 31, the welding positions of the cross beams 32 are optimally configured in combination with the bottom space of the frame, battery pack mounting holes 31a are formed on the upper surfaces of the two side longitudinal beams 31 corresponding to the mounting positions of the battery packs, and in order to increase the strength of the whole base plate, reinforcing inclined struts 33 are arranged at the corner joints between the longitudinal beams 31 and the cross beams 32; the welding of the both ends bottom of crossbeam 32 has the connecting block 34 that has the screw, connecting block 34 passes through the bolt and links to each other with the bottom of frame connector 3, adopts the connected mode of this kind of spiro union, trades the electric in-process, need not dismantle the connection between 2 upper portions of frame connector and the solebar, only need with main supporting support body 3 from the lower extreme dismantlement of frame connector 2 can, improved the efficiency of trading the electricity greatly.

Based on the consideration of space and the installation position of the battery pack, a section of transitional connecting bracket is welded at the front end beam 32 of the main support frame body 3, and the auxiliary support frame body 1 is connected with the main support frame body 3 through the transitional connecting bracket.
