Embodiment
In order that those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings and embodiment The utility model is described in further detail.
Referring to Fig. 1 to Fig. 6, the utility model provides a kind of Safety shell of lithium battery and ultracapacitor, including shell Phosphor bodies 1, multiple safety valves 2 are set in the surrounding side wall of the housing body 1.
In specific implementation, the housing body 1 is preferably shaped to cylinder.
In specific implementation, the multiple safety valve 2 is evenly distributed on the surrounding side wall of the housing body 1 at equal intervals.
It should be noted that the surrounding side wall in the housing body 1 sets multiple safety valves 2, lithium can be effectively improved The safety and reliability of battery and ultracapacitor.And the multiple safety valve 2 is evenly distributed on the housing at equal intervals The surrounding side wall of main body 1, the manufacture difficulty of safety valve 2 can be so reduced, improve yield rate, and improve the size of safety valve 2 Uniformity, and then ensure the uniformity of multiple openings pressure of safety valve.
In specific implementation, the multiple safety valve 2 is formed in one with the housing body 1, that is, shaping of producing once.
In specific implementation, the safety valve 2 it is in a unlimited number in two shown in Fig. 1, can be any more more than one It is individual, such as can be two to four.
In specific implementation, the multiple genesis analysis of safety valve 2 is in the surrounding side wall of the housing body 1.
In specific implementation, the housing body 1 is preferably the housing using aluminium alloy manufacture.
Referring to Fig. 2, Fig. 5, each safety valve 2 includes effective work department 21 and connecting portion 22, effective work department 21 are connected with the connecting portion 22 and positioned at the lower section of the connecting portion 22.
Include one respectively referring to Fig. 3, Fig. 4, the effective work department 21 and connecting portion 22 of each safety valve 2 in the lump Central connection 23 and two side portions 24, described two side portions 24 left and right sides phase with the central connection 23 respectively Link together, the thickness H of the central connection 23 is less than the thickness of any part in the side portion 24;
In specific implementation, the shape of cross section of the side portion 24 is preferably wing, certainly, according to the needs of user, institute The shape of cross section for stating side portion 24 is also designed to:Tranverse sectional thickness is with the side portion 24 and central connection 23 Any one shape that spacing increases and incrementally increased, for example, a sector.
In specific implementation, the thickness of possessed central connection 23 in effective work department 21 of the multiple safety valve 2 Identical (i.e. consistent), and the length of effective work department 21 of the multiple safety valve 2 is identical, it is more so as to be further ensured that The uniformity of individual opening pressure of safety valve.
Must be with external environment, sealing it should be noted that due to lithium battery and the self-characteristic of capacitor, inside it; When lithium battery and ultracapacitor are in some abnormalities, such as:Prolonged overcharge, overdischarge, cause lithium battery Constantly increase with the internal pressure of ultracapacitor, at this time, in order to avoid because the inside of lithium battery and ultracapacitor pressure Blast etc. seriously endangers caused by power increase, is typically provided with the main body of lithium battery and ultracapacitor in authorized pressure The safety valve that scope automatically turns on, is also explosion-proof valve.
For the utility model, in specific implementation, the Opening pressure scope of the safety valve 2 can be according to the needs of user Pre-set.For a user, the Opening pressure scope of safety valve specifically how is formulated:On the one hand safety valve is ensured After unlatching, security incident will not be caused;On the other hand, it is desirable to which the Opening pressure of safety valve should be higher than that the lithium during normal use The interiors of products upper limit of pressure such as battery and ultracapacitor, to ensure that the products such as lithium battery and ultracapacitor can for a long time just Often use.
It should be noted that if the Opening pressure setting of safety valve is too high, when safety valve is opened, safe thing may be caused Therefore;If the Opening pressure setting of safety valve is too low, the product such as lithium battery and ultracapacitor is during just production use, safety valve It may open, the life-span of the products such as lithium battery and ultracapacitor can be caused to terminate in advance.If in addition, lithium battery and super electricity The Opening pressure uniformity of the safety valve of the products such as container is poor, then may cause to cause security incident and cause lithium battery and surpass The life-span of the products such as level capacitor terminates in advance.
