[0036] In summary, the working principle:

[0037] For such a plastic shell of a lithium battery with a support skeleton, first, when we are about to use the plastic shell of the lithium battery, we place the lithium battery into the second shell 6, cover the first shell 1 and the second shell 6, and the positioning pin 7 on the first shell 1 is inserted into the positioning groove 8 on the second shell 6 to achieve the primary assembly and fixation of the first shell 1 and the second shell 6. The fixing buckle 4 on the first shell 1 and the fixing slot 11 on the second shell 6 are engaged with each other to achieve the secondary assembly and fixation of the first shell 1 and the second shell 6;

[0038] Secondly, rotate the rotating handle 3. The rotation of the rotating handle 3 drives the threaded rod 5 to rotate. The threaded rod 5 is in threaded fit with the threaded through hole on the first shell 1 and the threaded groove 14 on the second shell 6. The downward rotation of the threaded rod 5 controls the first shell 1 and the second shell 6 to achieve the third assembly and fixation;

[0039] Then, the support skeleton 10 and the reinforcing rib 13 installed inside the shell play a role in strengthening and fixing the internal structures of the first shell 1 and the second shell 6, and at the same time resist deformation caused by external forces;

[0040] Finally, when the lithium battery outputs inside the first shell 1 and the second shell 6, the lithium battery itself generates heat. The heat generated by the lithium battery is discharged through the ventilation holes 12 inside the aluminum plate 9 and the heat dissipation ports 2 on both sides of the first shell 1 and the second shell 6, realizing the heat dissipation effect inside the plastic outer shell of the lithium battery.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
