Abstract
The utility model discloses an anti-explosion outer shell of a lithium battery pack. The outer shell comprises an aluminous shell; an upper plastic end cover and a lower plastic end cover are respectively arranged at the upper part and the lower part of the aluminous shell; the upper end and the lower end of the aluminous shell are provided with an aluminous plate respectively and the shape of the aluminous plates corresponds to the shape of the end face of the aluminous shell; installing holes are formed in the aluminous plates; the aluminous plates at the upper end and the lower end of the aluminous shell are connected by connecting rods; and the aluminous plates at the upper end and the lower end of the aluminous shell are fixed on the aluminous shell by the connecting rods. The connecting rods are connecting rods with wires and the number of the connecting rods is 4. The aluminous plates at the upper end and the lower end are fixedly arranged at two ends of the aluminous shell by the connecting rods with wires, nuts and gaskets. According to the outer shell disclosed by the utility model, the battery pack is sealed up in the aluminous shell and the aluminous plates and the battery pack is ensured not to go outwards in explosion, so that people or other objects are not hurt and the personal and property safety is protected. The outer shell disclosed by the utility model can effectively reduce threat to the personal and property safety when the lithium battery pack explodes.
Description
Technical field
The utility model relates to a kind of Explosion-proof Design for the lithium battery assembly housing, relates in particular to a kind of explosion-proof type lithium battery assembly housing as an example of silverfish lithium electricity shell example.
Background technology
Because the technology of lithium battery group now is not also very ripe, the lithium electricity electric motor car that we use now seldom has explosion precaution, many explosion phenomenon have appearred in lithium electricity electric motor car on the market, threaten the safety of personal life and property, so there is very large potential safety hazard in the electric motor car of lithium electricity.
Summary of the invention
Problem to be solved in the utility model is not the technical problem that fundamentally solves the lithium battery group, but at a kind of protector of lithium battery group explosion time.The purpose of this utility model is to provide a kind of explosion-proof type lithium battery assembly housing.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of explosion-proof type lithium battery assembly housing, comprise: aluminum hull, the upper and lower of aluminum hull are equipped with respectively plastic end cover and lower plastic end cover, it is characterized in that: the two ends up and down of aluminum hull are respectively arranged with aluminium sheet, with installing hole, be connected with connecting rod between the aluminium sheet at two ends, aluminum hull up and down on aluminium sheet; The aluminium sheet at two ends, aluminum hull up and down is fixed on aluminum hull by connecting rod.
According to described explosion-proof type lithium battery assembly housing, it is characterized in that: the shape of the shape of described aluminium sheet and aluminum hull end face is corresponding; Described connecting rod is band silk connecting rod, and connecting rod is 4, and the aluminium sheet at two ends, up and down is fixedly mounted on the two ends of aluminum hull by band silk connecting rod, nut, packing ring.
According to described explosion-proof type lithium battery assembly housing, it is characterized in that: the thickness of described aluminium sheet is 1.5～2mm.
The utility model arranges two thick aluminium sheets at former lithium battery group aluminum hull two ends, with connecting rod and nut shim, aluminium sheet is fixed on aluminum hull, and battery pack is put in the middle of aluminium sheet, and battery pack is enclosed in aluminum hull and aluminium sheet.The utility model has the advantages that aluminium sheet intensity higher than working of plastics, fusing point is high, can guarantee that battery pack penetrates outside not at explosion time, therefore is unlikely to hurt people or other object, and the person and property safety are played a well protection.The utility model can effectively reduce the lithium battery group in the threat of explosion time to the person and property safety.
Description of drawings
Fig. 1 is contour structures schematic diagram of the present utility model.
Fig. 2 is the profile schematic diagram that the utility model removes upper plastic end cover and lower plastic end cover.
Fig. 3 is the structural representation that utility model is removed upper plastic end cover and lower plastic end cover and aluminum hull.
In accompanying drawing: 1, upper plastic end cover; 2, aluminum hull; 3, lower plastic end cover; 4, aluminium sheet; 5, connecting rod; 5, nut.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model explosion-proof type lithium battery assembly housing such as Fig. 1, Fig. 2, shown in Figure 3, comprise: aluminum hull 2, plastic end cover 1 and lower plastic end cover 3 are equipped with respectively in the upper and lower of aluminum hull 2, the two ends up and down of aluminum hull 2 are respectively arranged with aluminium sheet 4, with installing hole, be connected with connecting rod 6 between the aluminium sheet 4 at aluminum hull two ends Shang Xia 2 on aluminium sheet 4; The aluminium sheet 4 at aluminum hull two ends Shang Xia 2 is fixed on aluminum hull 2 by connecting rod 6.
In the utility model, the shape of the shape of aluminium sheet 4 and aluminum hull 2 end faces is corresponding; Aluminium sheet 4 is with installing hole, and described connecting rod is band silk connecting rod, and connecting rod is 4, and the aluminium sheet 4 at two ends, up and down is fixedly mounted on the two ends of aluminum hull 2 by band silk connecting rod, nut, packing ring.
Embodiment
The utility model is take silverfish lithium electricity shell as example.Explosion-proof type lithium battery assembly housing comprises: two of the thick aluminium sheets of 1.5～2mm, and each four of a band silk connecting rod, nut shims, wherein aluminium sheet is fixed on the aluminum hull outside of silverfish battery case, aluminum hull two ends is wrapped in the plastic housing the inside, in order to avoid affect outward appearance; Connecting rod and nut shim are used for being connected and fixed aluminium sheet, and the lithium battery group is placed in the middle of aluminium sheet.The utility model is fixed aluminium sheet with connecting rod and nut shim at aluminum hull two ends, and battery pack is put in the middle of aluminium sheet, and battery pack is enclosed in aluminum hull and aluminium sheet, even the battery pack explosion time also bursts out nowhere.
Advantage of the present invention be aluminium sheet intensity higher than working of plastics, fusing point is high, can guarantee that battery pack penetrates outside not at explosion time, therefore is unlikely to hurt people or other object, and the person and property safety are played a well protection.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and protection range are limited; under the prerequisite that does not break away from the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model all should fall into protection range of the present utility model.
