Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a lithium battery pack module convenient to mount and dismount includes a mounting plate 1, three separators 2 are fixedly connected inside the mounting plate 1, and the separators 2 have the same distance and are slightly larger than the diameter width of a lithium battery, so as to facilitate the fixation of the lithium battery; the four top corners of the upper surface and the lower surface of the mounting plate 1 are fixedly connected with supporting columns 3, one end, away from the top of the mounting plate 1, of each supporting column 3 at the top of the mounting plate 1 is fixedly connected with a first cover plate 4, one end, away from the bottom of the mounting plate 1, of each supporting column 3 at the bottom of the mounting plate 1 is fixedly connected with a second cover plate 5, the mounting plate 1, the first cover plate 4 and the second cover plate 5 are made of plastics, and; the mounting plate 1 is connected with the cover plate I4 and the cover plate II 5 only through the support columns 3, the four sides are in a ventilation state, the nickel sheet planes can be fixed horizontally and vertically conveniently, and the effect of connecting the lithium batteries in series and parallel is achieved.
