The bottom plate is also provided with a storage position for storing the second sealing plate 75 detached from the ventilation window 74, and the storage position is arranged side by side with the position of the air guide opening. In this embodiment, studs 76 for mounting the second sealing plate 75 are provided at the ventilation window position and the storage position of the air guide cover 7, and the second sealing plate 75 is sealed when being mounted at the ventilation window position, so that the air in the air guide channel can only enter the battery box from the air guide cover air outlet 72, but cannot enter the battery compartment. When the ventilation window is opened, the ventilation window is mounted on the stud 76 in the storage position, so that the ventilation window is prevented from being lost for the next use. The battery box, the wind scooper, the cabin body and other structures form a ventilation structure of the battery box.
The vehicle operation mode of the invention is as follows: when the temperature of the external environment is higher, for example, in summer, grid holes of an air inlet grid of the cabin body are correspondingly overlapped with rectangular holes of a first sealing plate at the rear part of the grid, air flow can pass through, a second sealing plate 75 on an air guide channel is fixed at a ventilating window through a butterfly nut of the second sealing plate 75, at the moment, air flow can only enter a battery box air inlet 81 of a battery box through an air guide cover air outlet 72 of the air guide channel of an air guide cover, cooling air of a passenger cabin is sucked into the battery box through a centrifugal fan on the battery box to dissipate heat of a module, and the module is exhausted to the external environment through a top cover exhaust fan 3 at the top of the battery box after the module is exhausted by the centrifugal fan, so that the external circulation of ventilation of the battery box is realized.
When the temperature of the external environment is lower, for example, in winter, an exhaust fan at the top of the battery compartment is sealed by an exhaust channel sealing plate, grid holes of an air inlet grid of the compartment body are staggered with first sealing plate rectangular holes at the rear part of the grid, air flow at the grid can not pass through, and meanwhile, a second sealing plate on the air guide channel is fixed beside an air exchange window through a second sealing plate butterfly nut, and the air flow at the air exchange window can pass through. When the centrifugal fan on the battery box works, the air flow of the passenger cabin cannot enter the battery cabin through the grille of the air inlet grille, and the air flow in the battery cabin can enter the air guide channel through the ventilation window on the air guide channel of the air guide cover, then enters the battery box air inlet 81 of the battery box through the air guide cover air outlet 72 of the air guide channel of the air guide cover, and is extracted by the centrifugal fan of the battery box. Because the top cover exhaust fan 3 at the top of the battery compartment is sealed, the gas pumped out from the centrifugal fan of the battery compartment does not enter the external environment, but enters the air guide channel of the air guide cover through the ventilation window of the air guide cover again to enter the battery compartment, so that the working temperature of the power battery can be kept by using the battery operation waste heat, and the air flow entering the battery compartment can also have a certain temperature, thereby preventing the working performance of the battery and the battery module from being influenced by the too low temperature of the battery cell in the battery compartment, simultaneously eliminating the air flow of the passenger compartment, reducing the air conditioning load and improving the energy saving effect of the whole vehicle. Because hot air directly enters the battery box, the heating efficiency of the battery box is improved, the temperature of the battery box is ensured, and the battery is in an optimal temperature range.
