Problems solved by technology

[0009] Although the above-mentioned patents all relate to passenger car cabin doors, and have also proposed some structural improvements, they do not consider the special requirements of the high-voltage electrical device compartment. It can not only effectively enter the car washing water, but also ensure the ventilation effect, so as to meet the special requirements of the high-voltage electrical device warehouse. No specific solution has been proposed, so further improvement is still needed

Embodiment 1

[0037] by attaching Figure 1-5 It can be seen that the present invention relates to a compartment door for high-voltage electrical components of a passenger car, including a cabin door panel 1, a built-in frame 2 and a cabin door grille bar 3, wherein the cabin door grille bar 3 is divided into an upper cabin door grille bar 4 , the middle cabin door grid strip 5 and the lower cabin door grid strip 6, the upper cabin door grid strip 4, the middle cabin door grid strip 5 and the lower cabin door grid strip 6 are grid strips of different structures respectively, respectively Arranged at the upper, middle and lower parts of the inner surface of the cabin door panel 1, the upper cabin door grille bar 4, the middle cabin door grille bar 5 and the lower cabin door grille bar 6 have gaps in the height direction of the adjacent grille bars. A waterproof and ventilated hatch with dislocation and overlapping nesting is formed.

[0038] Further, the upper cabin door grille bar 4, the m...

Embodiment 2

[0043] The structure of Embodiment 2 is the same as that of Embodiment 1. A cabin door for high-voltage electrical components of a vehicle includes a cabin door panel, a built-in frame and a cabin door grille strip, wherein the cabin door grille strip is divided into upper cabin door grille strips , the grille bar of the middle cabin door and the grille bar of the lower cabin door, the grille strips of the upper cabin door, the grille bar of the middle cabin door and the grille bar of the lower cabin door are grid bars of different structures respectively, and are respectively arranged on the inner surface of the cabin door panel The upper, middle and lower parts of the upper cabin door grille, the middle cabin door grille and the lower cabin door grille have gaps in the height direction of the adjacent grid bars. Waterproof and ventilated hatch.

[0044] It is just that the slope of all the outer hypotenuses mentioned above adopts a slope of 6--15 degrees intersecting the hor...

Abstract

The invention relates to a waterproof heat radiation method and device for a storehouse door of high voltage electric parts for a passenger car. According to the characteristics of rainwater and hydraulic monitor water, the storehouse door of the high voltage electric parts for the passenger car is divided into three parts, each part adopts different structural cabin door grilles , so that the storehouse door of the high voltage electric parts for the passenger car can effectively prevent the rainwater and the hydraulic monitor water from entering, and the amount of ventilation wind required by launching can be ensured. The storehouse door of the high voltage electric parts for the passenger car comprises a cabin door board, a built-in framework and the cabin door grilles, wherein the cabin door grilles are divided into upper cabin door grilles, middle cabin door grilles and lower cabin door grilles; the upper cabin door grilles, the middle cabin door grilles and the lower cabin door grilles are respectively different structural grilles and are respectively arranged at the upper part, the middle part and the lower part of the inner side of the cabin door board; the upper cabin door grilles, the middle cabin door grilles and the lower cabin door grilles are overlapped and nested in a malposition manner with gaps in the height direction of the adjacent grilles, so that a waterproof ventilation cabin door in gap malposition overlapped and nested manner is formed.

Description

technical field [0001] The invention relates to a method and device for waterproofing automobiles, in particular to a method and device for ventilating and waterproofing a cabin door of a high-voltage electric device in a large passenger car. The working conditions are not very high. Background technique: [0002] Today's large buses, especially the rear of electric or hybrid buses, are equipped with high-voltage electrical device compartments. Auxiliary power supply, energy storage system control box and other high-voltage working parts, the cabin where these parts are located is referred to as the high-voltage electrical device compartment; the high-voltage electrical components in the high-voltage electrical In order to dissipate high heat from electrical devices, it is necessary to take waterproof measures to prevent water from splashing in. Generally, an active air suction device is installed in the cabin, and a hatch is opened at the rear of the passenger car for ai...
