Embodiment 1

[0038] An embodiment of the present application provides a lithium battery pole module.

[0039] like figure 1 and figure 2 As shown, a lithium battery pole module includes a pole 1 , a wrapping ring 2 and a sealing ring 5 .

[0040] The pole 1 includes a cylinder 11 and lugs 12, and the lugs 12 are fixed on the circumferential side of the cylinder 11. In this embodiment, the cylinder 11 is cylindrical, and two lugs 12 are provided. The cylinders 11 are uniformly distributed in the circumferential direction, and the lugs 12 and the cylinders 11 are integrally arranged. In other embodiments, the number of lugs 12 may also be one or other numbers, and the cross-section of the cylinder 11 may also be rectangular or other polygonal.

[0041] The wrapping ring 2 surrounds the outer periphery of the pole 1, and the wrapping ring 2 is fixed with a ring-shaped support edge 3, the ring-shaped support edge 3 abuts against the edge of the end face of the pole 1, and the ring-shaped s...

Embodiment 2

[0053] An embodiment of the present application provides a lithium battery pole module.

[0054] The lithium battery pole module of the present application is the same as that of the first embodiment.

[0055] The application also discloses a lithium battery top cover.

[0056] A top cover for a lithium battery. The difference between this embodiment and the first embodiment lies in that the connection mode between the rivet 8 and the lower plastic plate 7 is different.

[0057] like Figure 9 and Figure 10 As shown, the rivet 8 is pre-fixed on the lower plastic plate 7, the cap of the rivet 8 is fixed on the lower plastic plate 7, the cap of the rivet 8 is injection molded on the lower plastic plate 7, and the shank of the rivet 8 passes through the cover plate 6 , ring support edge 3 and pole 1. The lower plastic plate 7 is provided with an embedding groove 93 for accommodating the embedding groove 93 sleeved on the limiting ring 92 of the sealing sleeve 9 .

Abstract

The invention provides a lithium battery pole module and a lithium battery top cover, and belongs to the technical field of power batteries. Specifically, the lithium battery pole module comprises a pole and a wrapping ring, wherein the wrapping ring surrounds the periphery of the pole, an annular supporting edge is fixed in the wrapping ring, the annular supporting edge abuts against the edge of the end face of the pole, and through holes which simultaneously penetrate through the pole and the annular supporting edge are formed in the pole and the annular supporting edge. According to the treatment scheme, the size and the weight of the pole are reduced, and the mounting mode of the lithium battery pole module on the top cover is changed, so that the overall weight of the lithium battery top cover is reduced.

Description

technical field [0001] The present application relates to the field of power batteries, in particular to a lithium battery pole module and a lithium battery top cover. Background technique [0002] Driven by the market, the demand for lithium-ion power batteries is increasing, and at the same time, higher requirements are placed on the energy density of lithium-ion power batteries. [0003] Existing lithium batteries mainly include a shell, a top cover, and a battery cell. The top cover of the lithium battery is provided with a pole connecting the internal circuit and the external circuit. The ordinary pole is large in size and relatively heavy in weight, resulting in a lithium battery top cover. The weight is heavier. Contents of the invention [0004] In view of this, the present application provides a lithium battery pole module and a lithium battery top cover, which solves the problem of heavy lithium battery top covers in the prior art, and better meets the energy de...
