Shape size be engaged with the flange of open casing, the sealing ring be provided with it is corresponding with the bolt hole on open casing
Through hole；The side outer wall of the main box is provided with rectangular indentation, the periphery of the rectangular indentation be provided with open casing
The second corresponding bolt hole of bolt hole；The sealing ring is placed between the flange and main box of open casing, main box and spacious
Mouth casing is bolted to connection.
The open casing is cuboid or cube structure.
The width of the flange is 14~20mm.
The spacing of adjacent bolt hole on the flange is 60~80mm, and the aperture in spiral shell inspection hole is 4~Φ of Φ 8mm.
The material of the sealing ring is rubber.
Utility model works mode：Battery modules are placed in main box, and the wire harness in battery modules is concentrated from main tank
Draw, be placed in the open top container body of fixed beam, it is necessary to be connected with external equipment at rectangular indentation on the side outer wall of body
Wire harness drawn from the fairlead of the side of open casing, sealing ring is placed on the flange of open casing, it is logical on sealing ring
Hole is alignd one by one with the bolt hole of open casing, and then open casing is close on main box, the bolt hole on open casing
Correspond with the second bolt hole on main box, be fixedly connected with main box with open casing finally by bolt.
The beneficial effects of the utility model：1st, in view of the technique of carbon fiber casing unitary mould exploitation and composition limits at present,
The main box of the open casing of fixed beam and placement battery modules is separately fabricated separately, Mold Making is simple, and expense is low；2、
Sealing ring is added between open casing and main box, based on carbon fibre material characteristic, entirely through bolt connection, sealing
Good, intensity is high.
