Embodiment 1

[0036] A battery cover of this embodiment, such as Figure 1-Figure 4 As shown, it includes a cover plate body 1 , a first output terminal, a second output terminal, a safety trigger device 7 and a cell negative pole 3 .

[0037]The first output terminal is electrically connected to the battery inner core 6 , the first output terminal is the positive terminal 8 of the battery, and the positive terminal 8 is electrically connected to the cover body 1 .

[0038] The positive end 8 includes a positive pole 81 , a connecting plate 9 , a conductive sheet 10 and a positive tab 92 . The positive pole 81 is disposed on the cover body 1 , one end of the positive pole 81 is electrically connected to the load, and the other end is electrically connected to the battery inner core 6 through the positive tab 92 . One end of the connecting plate 9 abuts against the side wall of the positive pole 81 away from the battery cover, and the other end is connected to the cover body 1 for fixing th...

Embodiment 2

[0048] The present invention also includes a battery, which includes a casing 11 , a battery inner core 6 and a battery cover. The battery inner core 6 is arranged in the housing 11; the battery cover described in the first embodiment, the battery cover is connected to the housing 11 to seal the battery inner core 6 in the housing 11 .

Abstract

The invention relates to the technical field of batteries, in particular to a battery cover plate and a battery. The battery cover plate comprises a cover plate body, a first output end, a second output end and a safety trigger device and also comprises a battery cell negative electrode, wherein the first output end is electrically connected with a battery inner core, one of the first output end and the second output end is a positive end of the battery, the other one of the first output end and the second output end is a negative end of the battery, the safety trigger device is used for triggering so that the first output end and the second output end are electrically conducted by the cover plate body to form short circuit when difference between internal air pressure and external air pressure of the battery exceeds a threshold, the battery cell negative electrode is arranged on the cover plate body, one end of the battery cell negative electrode is connected with the second output end via a fuse, the other end of the battery cell negative electrode is electrically connected with the battery inner core, the battery cell negative electrode is also provided with a connection part, and the connection part is used for electrically connecting a load. The battery comprises a shell, the battery inner core and the battery cover plate, wherein the battery inner core is arranged in theshell, and the battery cover plate is connected with the shell so that the battery inner core is sealed in the shell. The battery cover plate has the advantages that the battery cover plate can be gradiently used after the fuse is molten, and more resources are saved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery cover plate and a battery. Background technique [0002] With the continuous development and progress of human society and the continuous improvement of human living standards, the demand for energy is also increasing, especially the demand for mobile and portable energy devices. Among them, the battery as a mobile energy storage has developed rapidly, especially when the battery is used in the transportation field, it has great advantages over the traditional internal combustion engine fuel as power. [0003] At present, in the prior art, such as the Chinese patent document CN206947390U, a battery explosion-proof cover assembly with an external easy-to-replace safety protection device is disclosed. Outside the battery cover, the lead-out end of the positive pole is provided with a first Two positive connection blocks, a second safety installation platform is set on ...
