Embodiment
The embodiment of the utility model lithium battery protective cover, shown in Fig. 1-7, the protective cover 1 of present embodiment is installed on the battery cover 4 of lithium battery, protective cover 1 comprises cover plate 11 and around the jacket wall 12 that is located at cover plate 11 bottoms, is fixed with on the inner peripheral surface of described jacket wall 12 along turning edge 3 in the jacket wall 12 circumferential distributions.The material of described protective cover 1 adopts engineering plastics, relies on the elastic deformation characteristic of engineering plastics, turns edge 3 and outer being clasped of turning edge of battery cover 4 convex platforms 5 by interior, realizes fixedlying connected of protective cover 1 and battery cover 4.
In the present embodiment, turning edge in described 3 can be the circulus along protective cover 1 circumferential arrangement.
The jacket wall 12 upper edge protective covers 1 of above-mentioned protective cover 1 circumferentially vertically offer many slits, each slit is divided into a plurality of ligulate members 2 with the outer wall of protective cover 1, turn edge in described and 3 be arranged on each ligulate member 2, as required, can remove certain ligulate member wherein, be convenient to bus and signals collecting line like this and can pass through protective cover 1, can also play the effect of ventilation after removing.
The embodiment of a kind of lithium battery of the utility model, shown in Fig. 1-7, comprise battery cover 4 and be arranged on the protective cover 1 that is used to protect battery electrode column on the battery cover 4, the upper end of battery cover 4 has been wholely set boss 5, the outer peripheral face upper edge boss 5 of described boss 5 circumferentially is fixed with outward extending outer turning edge, the structure of the protective cover 1 of present embodiment lithium battery is consistent with the protective cover structure of the foregoing description, and its content does not repeat them here.
In the present embodiment, described outer turning edge can be the circulus along boss 5 circumferential arrangement.
The utility model lithium battery maintenance and when checking utilizes the elasticity of protective cover 1 itself, can realize separating of protective cover 1 and battery cover 4 easily, after maintenance and inspection finish, equally also can easily protective cover 1 be covered.
