Alternatively, the mating surface of described nose and described cavity is " Ω " type.
Alternatively, the upper surface of described sealing ring has upper glue layer, and described sealing ring is connected with described battery pack upper cover through described upper glue layer.
Alternatively, also have bolt, described bolt is fixed described upper cover, described sealing ring and described base plate press seal.
Alternatively, described bolt is by being positioned at the connecting hole on described sealing ring, and is positioned at that described upper cover is connected with installing hole on described base plate and press seal is fixed.
Alternatively, also have sleeve pipe, described sleeve pipe is embedded in the installing hole of described upper cover and the connecting hole of described sealing ring, and described bolt is connected with the installing hole of described base plate through described sleeve pipe.
Alternatively, between described bolt and described upper cover, there is elastic washer.
Alternatively, the thickness of described sealing ring is 6mm, and described sealing ring has elastic deformation between described upper cover and described base plate, and described elastic deformation is 2mm to 3mm.
Seal of the present invention use easy for installation, long-term has reliability.
Accompanying drawing explanation
Fig. 1 is seal schematic diagram of the present invention;
Fig. 2 is Figure 1A place enlarged drawing; With
Fig. 3 is scheme of installation of the present invention.
Reference numeral: 1 battery pack upper cover; 2 seals, 3 battery pack base plates, 4 sealing ring one, 5 sealing ring two, 6 sealing ring three, 7 sealing ring four, 8 bolts, 9 sleeve pipes, 10 elastic washers, 11 noses, 12 cavitys, 21 upper glue layers, 22 lower glue layers.
Embodiment
As shown in Figures 1 to 3, the invention provides a kind of battery pack seal 2 of pure electric automobile, described seal 2 is between the upper cover 1 of described battery pack and the base plate 3 of described battery pack, wherein: described seal 2 is spliced from beginning to end by least two sealing rings.
As shown in the figure, as preferred embodiment, described sealing ring in the present invention comprises four, and described four sealing rings are spliced to form the rectangle corresponding with described upper cover 1 outline from beginning to end, comprise as shown in the figure sealing ring 1, sealing ring 25, sealing ring 36 and sealing ring 47, they form a rectangular frame.For example in embodiment, upper cover rectangle is long 1233mm, wide 1034mm.
As one embodiment of the present of invention, in described stitching portion, described one of them sealing ring has nose 11, and described wherein another sealing ring has cavity 12, and described cavity 12 holds described nose 11, to splice described sealing ring.
Wherein preferred, the mating surface of described nose and described cavity is Ω type.
As another embodiment of the present invention, the upper surface of described sealing ring has upper glue layer 21, and described sealing ring is connected with described battery pack upper cover 1 through described glue-line.Or the lower surface of described sealing ring has lower glue layer 22, described sealing ring is connected with described battery pack base plate 3 through described upper glue layer 21.
As improvement, it also has bolt 8, and described bolt 8 is fixed described upper cover 1, described sealing ring 2 and described base plate 3 press seals.
Wherein preferred, described bolt 8 is by being positioned at the connecting hole on described sealing ring, and is positioned at that described upper cover 1 is connected with installing hole on described base plate 3 and press seal is fixed.
As illustrated improvement, it also has sleeve pipe 9, and described sleeve pipe 9 is embedded in the installing hole of described upper cover 1 and the connecting hole of described sealing ring 2, and described bolt 8 is connected with the installing hole of described base plate 3 through described sleeve pipe 9.
As preferred scheme, between described bolt 8 and described upper cover 1, there is elastic washer 10.
As embodiments of the invention, the thickness of described sealing ring is 6mm, and described sealing ring has elastic deformation between described upper cover 1 and described base plate 3, and described elastic deformation is 2mm to 3mm.
For the embodiment in accompanying drawing 1 to 3, describe below, for the battery pack seal of pure electric automobile, comprise sealing ring one, sealing ring two, sealing ring three, sealing ring four, sleeve pipe.During installation, successively sealing ring one, sealing ring two, sealing ring three, sealing ring four-way being crossed to upper surface mating surface is bonded in battery pack and covers, then respectively sleeve pipe is embedded in to the Kong Weizhong that sealing ring is corresponding, finally by the urgent of bolt between battery pack upper cover and battery pack base plate, seal is fixed;
