Rib, the corner location and the first ribs of first ribs and the angular position of the second ribs are provided with described
Three ribs.By the way that third ribs is arranged, in this way add the corner location of the first ribs and the first ribs and second
The angular position of strong rib forms the firm reinforcement rib structure of triangle, further strengthen ribs on coping plate ontology plus
Potent fruit.
As the preferred embodiment of power battery coping plate described in the utility model, first ribs, second are reinforced
It is connected with each other between rib and third ribs；By the interconnection of three, the reinforcement rib structure of coping plate ontology is made to form one
Body improves the strength and stiffness of coping plate ontology.
As the preferred embodiment of power battery coping plate described in the utility model, the coping plate ontology is additionally provided with explosion-proof
Valve, a plurality of second ribs are separately positioned on the two sides of explosion-proof valve.Due to being equipped with explosion-proof valve among coping plate ontology, lead to top cover
Intensity among piece ontology is lower；Therefore, it by the way that the second ribs is arranged in explosion-proof valve two sides, can improve among coping plate ontology
Intensity.
As the preferred embodiment of power battery coping plate described in the utility model, the ribs be groove rib and/or
Convex closure rib.The groove rib and convex closure rib are arranged on coping plate ontology by stamping forming mode.
As the preferred embodiment of power battery coping plate described in the utility model, the groove rib width is 0.5-3mm,
Depth is 0.1-2mm.By the way that above-mentioned numerical value is arranged, it can guarantee that groove rib in the case where not influencing coping plate assembly, improves top
The intensity of cover plate ontology.
As the preferred embodiment of power battery coping plate described in the utility model, the convex closure rib width is 0.5-3mm,
Height is 0.1-2mm.By the way that above-mentioned numerical value is arranged, it can guarantee that convex closure rib in the case where not influencing coping plate assembly, improves top
The intensity of cover plate ontology.
The utility model has the beneficial effect that a kind of power battery coping plate of the utility model, including coping plate sheet
The upper surface of body, the coping plate ontology is provided with ribs.Compared with prior art, the utility model passes through in power battery
Ribs is set on coping plate, on the one hand, under conditions of not increasing coping plate thickness, can improve in this way coping plate intensity and
Rigidity, makes coping plate that buckle and fragmentation to be less likely to occur, improves the security performance of power battery；On the other hand, in this way
The production material that coping plate can be saved mitigates the weight of coping plate, has reached reduction production cost and has improved power battery energy
The effect of metric density.
