The port of the water interception cover 962 is close to the ventilation grille 92 on the side wall of the shell 91, and the ventilation holes 965 are uniformly formed in the inclined side wall of the water interception cover 962, and the ventilation holes 965 are only formed in the inclined side wall of the water interception cover 962 above the horizontal line of the connecting rod 963, and the inclined side wall of the water interception cover 962 below the horizontal line of the connecting rod 963 is solid.
Specifically, when the passenger car runs, the air flow is driven to enter from the ventilation grille 92 on the side wall of the shell 91, the air flow carrying rainwater firstly impacts the water interception cover 962, the turbine fan 964 on the outer wall of the connecting rod 963 inside the water interception cover 962 is driven to rotate by the air flow, the water is rotationally blocked to slide into the water storage tank 95 along the inner wall of the water interception cover 962 to be utilized, the air flow is discharged to the isolation cloth sleeve 912 through the ventilation hole 965 on the side wall on the upper part of the water interception cover 962, moisture is absorbed by the isolation cloth sleeve 912 and then enters the air supply channel 94, and the rotation of the turbine fan 964 can be used for blowing when blocking the rainwater, so that the ventilation effect on the interior of the passenger car is enhanced.
Example 3: the energy consumption and light weight design problem of the whole vehicle and parts are solved; the invention improves the selection of each part of the car body,
based on the specific structures of embodiment 1 and embodiment 2, the lightweight design of the front structure of the full-load pure electric city bus is specifically as follows: the main frame structure of the car body 1 is preferably manufactured by processing magnesium aluminum alloy materials; the shell 91, the baffle 96, the L-shaped drainage plate 910 and the like of the ventilation member 9 are preferably manufactured by processing carbon fiber or ultra-light composite engineering plastic materials; the structures such as the pedal 81, the first side plate 83, the second side plate 84, the movable connecting piece 85, the supporting rod 86 and the fixing plate 87 of the pallet 8 are preferably made of magnesium-aluminum alloy materials, and considering that the pallet 8 is not only built in the vehicle body 1, but also can be automatically stretched out to avoid the problem that the passengers get wet the shoes and the clothes when stepping on the water to get on or off the vehicle to influence traveling, the pallet 8 must be considered for one purpose of light weight, so that in the process of preparing the pallet 8, main parts are made of magnesium-aluminum alloy materials, the light weight requirement can be achieved from the weight of the whole structure of the pallet 8, and the corresponding functions can be met.
In conclusion, through the embodiments, the problems that the internal air quality is poor due to the fact that the windows of the bus are closed in rainy days and the passengers get on and off the bus stop board in the low-lying city easily to wet shoes and clothes can be solved; the light-weight environment-friendly material is mainly used for the components of the structure, such as light magnesium aluminum alloy, carbon fiber, ultra-light composite engineering plastic and the like, so that the weight and energy consumption of the whole vehicle are reduced, and meanwhile, the novel light-weight material also has ultra-strong corrosion resistance and ageing resistance, so that the light-weight environment-friendly material is very suitable for the use scene of the structure in humid and insolation.
