In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic view of the internal structure of the present invention.
Detailed Description
As shown in fig. 1 and 2, the lithium battery pack includes a spliced main body case 1, a circular mounting cavity 13 is provided inside the main body case 1, two bearings 4 are embedded and mounted at two side axes of the mounting cavity 13, a hollow shaft sleeve 2 is mounted in the bearing holes of the two bearings 4, and the hollow shaft sleeve 2 passes through the bearing holes of the two bearings 4 and extends out of the main body case 1;
the middle of the hollow shaft sleeve 2 is provided with a hollow wire outlet channel 8, the outer side end extending surfaces of the wire outlet channels 8 are all opened, the outer wall of the hollow shaft sleeve 2 surrounds the hollow shaft sleeve in a circle and is welded and fixed with more than one rotating blade 7, the middle of each rotating blade 7 is provided with a battery installation cavity with two opened ends in a penetrating way, and lithium batteries 14 are all installed in the battery installation cavities and are glued, bonded and fixed;
the thickness of lithium cell 14 equals the thickness of rotating vane 7, and the positive and negative face of lithium cell 14 and the both sides terminal surface parallel and level of rotating vane 7, the power output of every lithium cell 14 all passes rotating vane 7 and the wire hole on the hollow axle sleeve 2 through wiring 3 and stretches into in the passageway 8 of being qualified for the next round of competitions in the middle of the hollow axle sleeve to draw forth from one side open end of passageway 8 of being qualified for the next round of competitions.
In this embodiment, the main body case 1 of concatenation formula includes a semicircular first casing 11 and a semicircular second casing 12, and first casing 11 assembles into a circular main body case with second casing 12 each other, and a locking screw 5 all locks into in the concatenation department outside of first casing 11 and second casing 12, through dismantling first casing 11 and second casing 12, can carry out the fast operation to inside, and the lithium cell group dismouting is very convenient.
The circular structure can ensure that each lithium battery can be sufficiently dispersed under almost the same volume, only a small number of lithium batteries are listed in the embodiment, but if a plurality of rotating blades are arranged, the number of the lithium batteries can be increased, in the same circular space, the number of the lithium batteries can not be increased by adopting a stacking mode, and on the contrary, the rotary type installation mode is adopted in the invention, so that the space can be effectively and reasonably utilized, and the lithium batteries can be effectively dispersed while the lithium batteries as many as possible are installed, so that the lithium batteries are not contacted, and heat is not mutually transferred.
