Abstract
The utility model relates to an explosion-proof cover plate for a power lithium battery. The explosion-proof cover plate comprises a plate body of the cover plate, wherein the plate body of the cover plate is horizontally arranged, a boss is upwards stamped on the plate body of the cover plate, the boss comprises a boss top wall, the boss top wall is horizontally arranged, a boss side wall is hermetically and fixedly connected below the peripheral ring of the boss top wall, the boss side wall is vertically arranged, and the lower end of the boss side wall is hermetically and fixedly connected with the plate body of the cover plate; explosion-proof marks are engraved on the boss side wall; the explosion-proof marks are horizontally formed; the thickness of the boss side wall is smaller than that of the boss top wall and smaller than that of the plate body of the cover plate. The explosion-proof cover plate provided by the utility model is of an integral structure, the boss is molded in a stretching way, the structure is simple, and the processing is easy. The structure is not provided with an explosion-proof hole, liquid leakage is avoided, and the depth of the explosion-proof marks is easy to control; compared with a way of riveting or welding an explosion-proof mold, the explosion protection is more stable.
Description
Technical field
The utility model relates to a kind of battery cover board, relates in particular to a kind of dynamic lithium battery explosion-proof covering board.
Background technology
At present, the blast resistance construction of the cover plate of power lithium used on market is first on the cover plate plate body, to get centralized positioning step hole, then welding or riveting rupture pressure disc in this stepped hole are finally got explosion-proof trace, this kind of structure processed complex on rupture pressure disc, leakage easily appears, explosion-proof unstable.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, dynamic lithium battery explosion-proof covering board that result of use is good.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of dynamic lithium battery explosion-proof covering board, comprise the cover plate plate body, the cover plate plate body is horizontally disposed with, it is characterized in that: the punching press that makes progress of cover plate plate body has boss, boss comprises the boss roof, and the boss roof is horizontally disposed with, the airtight boss sidewall that is fixedly connected with below boss roof border, the boss sidewall vertically arranges, boss side wall lower ends and the cover plate plate body is airtight is fixedly linked; Be carved with explosion-proof trace on the boss sidewall.Explosion-proof trace level is offered.The thickness of boss sidewall is less than the thickness of described boss roof, also is less than the thickness of cover plate plate body.
The utility model is the integral type structure, and the mode adopt stretched makes boss forming, simple in structure, be easy to processing.This kind of structure blast hole in the air, not there will be leakage, and the degree of depth of explosion-proof trace is easy to control, and with the mode of riveted joint or the anti-burst-mode of welding, compares, explosion-proof more stable.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model reality.
In accompanying drawing:
1, cover plate plate body; 2, boss sidewall; 3, boss roof; 4, explosion-proof trace.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
A kind of dynamic lithium battery explosion-proof covering board, as shown in Figure 1, comprise cover plate plate body 1, cover plate plate body 1 is horizontally disposed with, and cover plate plate body 1 upwards punching press has boss, and boss comprises boss roof 3, boss roof 3 is horizontally disposed with, the airtight boss sidewall 2 that is fixedly connected with below boss roof 3 borders, boss sidewall 2 vertically arranges, boss sidewall 2 lower ends and cover plate plate body 1 is airtight is fixedly linked; Be carved with explosion-proof trace 4 on boss sidewall 2.In the present embodiment, described explosion-proof trace 4 levels are offered.The thickness of described boss sidewall 2 is less than the thickness of described boss roof 3, also is less than the thickness of described cover plate plate body 1.
In the utility model, the ironing that makes progress of cover plate plate body goes out a boss, carves the explosion-proof trace with certain depth in the zone of boss sidewall attenuation.Under certain pressure, with the boss sidewall of explosion-proof trace, can at first break, therefore can play the effect of battery anti-explosion.The stable easily processing of this blast resistance construction, technique is simple, and production cost is low.
The utility model is the cover plate integral structure, is easy to moulding, has reduced making step, has reduced production cost, not there will be the phenomenon of leakage, makes explosion-proof effect more stable.
