A connection structure for the frame of a battery pack housing for new energy vehicles
ActiveCN121726658BReduce risk of leakageincrease frictionEngine sealsSecondary cellsInterference fitManufacturing technology
This invention belongs to the field of battery manufacturing technology, specifically a connection structure for the frame of a battery pack housing for new energy vehicles. It includes a water-cooled connection assembly, which comprises a base plate with flow channel ports at both ends. A water-cooled sealing strip is installed within each flow channel port. The water-cooled sealing strip, made of rubber, has a stepped recessed buffer cavity in the middle and an inverted conical structure formed by two inclined surfaces at its head. The interference fit between the sealing strip and the channel creates multiple sealing surfaces, maintaining partial sealing even if some loosening occurs. This also enhances friction with the inner wall of the channel, effectively reducing the risk of condensate leakage. The outer surface of the water-cooled sealing strip has diagonal anti-slip stripes, which can mechanically engage with the inner wall of the flow channel port, reducing axial movement and further improving structural stability.
