Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. 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 1:

In embodiment 1, the single frame is a polyhedron structure, the battery box is fixed in the single frame and is detachably fixed, the battery box can be connected through bolts or placed in the single frame through rails, and then the battery box is locked to run through the rails, so that the purpose of carrying out the battery box is achieved; the single body frames are movably connected, different polyhedral structures can be arranged in the shape of the single body frames, the battery box only needs to be stored, and the single body frames can be conveniently and movably connected, and under the condition that the single body frames are polyhedral, the single body frames can be connected through polyhedral frames, such as bolting and nut connection, so that the frames are connected together; the connection can also be realized through the end faces of polyhedrons, and the connection mode can also be bolt connection and nut connection. The technical scheme of the embodiment 1 can realize that different battery capacity designs, such as one battery box or a plurality of battery boxes, are carried out for electric vehicles with different functions and electric vehicles with different sizes, and the expansion and modification are convenient, and under the condition that the battery capacity needs to be added, the addition of the single frame and the battery box is continued under the condition that the space allows; under the condition that the electric motor car was retrieved, during battery recycle, this combined battery bracket also can recycle, according to the electric motor car that later stage used once more and allowed the space capacity of depositing the battery case, the selectivity adds or reduces battery monomer frame, can satisfy the space capacity and the battery capacity of depositing the battery of new electric motor car, has the extension, repacking convenience, advantage that the recoverability is strong, just the utility model provides a combined battery bracket structure itself is simple, and the practicality is strong, has fine economic nature and practicality.
