Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings, but the present invention is not limited thereto.
As shown in fig. 1, 3 and 4, the air guide device provided by the invention comprises an air guide pipe 1, wherein the air guide pipe 1 forms an air duct for communicating a passenger compartment and a battery compartment of a vehicle, the air guide device further comprises a base 2 which is arranged above the air guide pipe 1 and is used for penetrating the air guide pipe 1, the base 2 adopts omega-shaped bottom plate and side beam profile assembly welding pieces, the cross section of the base is as shown in fig. 5, and the base is used for bearing a bamboo floor around the base and is welded and fixed on a vehicle body side sealing plate 9 of the vehicle in use for preventing self-tapping nails from being exposed. In the present embodiment, 4 air guide pipes 1 are arranged in parallel at intervals. An air inlet box 4 is covered on the base 2, and the air inlet box 4 is buckled on the inner side wall of the vehicle body side sealing plate 9 and is welded with the base 2. The air inlet box 4 and the base 2 form a dust cover, and the air guide pipe 1 is communicated with the inner cavity of the dust cover. The air inlet box 4 is provided with a vent hole 5 at one side of a vehicle body side sealing plate 9 in parallel, the vent hole 5 is provided with a ventilating grid 8 communicated with the inside of a vehicle through screws, the ventilating grid 8 is provided with a plurality of shutters, and windows of the shutters are arranged downwards, so that water drops can be effectively prevented from entering a battery compartment through the air guide pipe 1.
An inner cover body is arranged in a dust cover formed by the air inlet box 4 and the base 2, in the embodiment, the inner cover body is a baffle plate 10 which is arranged on the base 2 and is arranged in parallel with the air permeable grille 8, as shown in fig. 2, the baffle plate 10 is composed of an outer side wall, an inner side wall, an upper side wall and a bottom wall, wherein the outer side wall and the inner side wall are both parallel with the air permeable grille 8, the outer side wall is buckled in the inner side wall of the vehicle body side sealing plate 9, and the inner side wall of the baffle plate 10 forms a wind shielding side face for blocking dust and water drops entering. In the present embodiment, both sides of the wind-shielding side surface in the horizontal direction are set as the front side and the rear side. The bottom of the inside wall of the baffle 10 is of a step-shaped structure, the bottom wall of the baffle 10 is provided with a folded edge 3 matched with the height of a step, a front side air inlet 6 and a rear side air inlet 7 are formed between the folded edge 3 and the inner side wall, the outer side wall and the upper side wall of the baffle 10, and the bottom openings of the front side air inlet and the rear side air inlet are larger than the bottom wall of the baffle 10 along the height. Because the air guide pipe 1 penetrates through the base 2, in order to ensure that the air guide pipe 1 is communicated with an air flow channel formed in the baffle 10 through the bottom wall of the baffle 10, the width of the folded edge 3 is smaller than that of the base 2. In order to prevent water drops or dust and the like which cannot be blocked by the air-permeable grille 8 from directly entering the air guide pipe 1, the length and the width of the wind shielding side surface of the baffle plate 10 are respectively greater than the length and the width of the air-permeable grille 8; meanwhile, in order to improve the ventilation and heat dissipation effects, the sum of the cross-sectional areas of the front side air inlet 6 and the rear side air inlet 7 is larger than the sum of the effective air inlet hole areas of the air-permeable grille 8.
The air in the passenger compartment enters the air inlet box 4 through the air permeable grille 8, changes the direction of the air flow after meeting the wind shielding side surface of the baffle 10, enables the air flow to flow along the two sides of the wind shielding side surface, respectively enters the air guide pipe 1 through the front side air inlet 6 and the rear side air inlet 7, and flows into the battery compartment along the air guide pipe 1 to dissipate heat or preserve heat of the battery compartment. After water drops or dust in the vehicle, which cannot be blocked by the water inlet grille 8, blows on the wind shielding side face of the baffle plate 10, the water drops or the dust can slide down to the step face of the step-shaped inner side wall of the baffle plate 10 along the wind shielding side face, and cannot directly enter the air guide pipe 1. In addition, when the passenger compartment is opened with the warm air, steam can follow 8 entering of ventilative grid and advance in the wind box 4, baffle 10 surface temperature is lower during the initial time, can form the drop of water when the side contact of keeping out the wind of steam and baffle 10 and directly slide to the diapire of baffle 10 along the side of keeping out the wind, because the diapire has hem 3, the drop of water can not directly flow into in the guide duct 1, along with the circulation of warm air, the drop of water can evaporate gradually and reduce, guarantees whole air ducting's waterproof performance.
In the above embodiment, the air in the passenger compartment enters the air guide pipe through the front and rear air inlets, and in other embodiments, the outer side wall of the baffle plate is not buckled on the inner side wall of the vehicle body side sealing plate, so that a certain gap is left between the outer side wall of the baffle plate and the inner side wall of the vehicle body side sealing plate, and the air inlet is arranged on the outer side wall of the baffle plate.
In the above embodiment, the bottom wall of the baffle plate is provided with the folded edge structure, so that the bottom edges of the front and rear air inlets are higher than the base, and water drops or dust is prevented from flowing into the air guide pipe directly along the base. In other embodiments, the bottom wall of the baffle plate is not provided with a structure with folded edges, and the height of the air guide pipe penetrating out of the bottom wall of the baffle plate is only required to be increased.
In the above embodiments, the baffle includes the outer side wall buckled on the inner side wall of the vehicle body side sealing plate, in other embodiments, the baffle may not have the outer side wall, and the air inlet channel is formed directly through the space between the upper side wall, the inner side wall, the bottom wall and the vehicle body side sealing plate.
The vehicle includes a vehicle body, a battery compartment disposed on the vehicle body, and an air guide device, and the structure of the air guide device is the same as that of the air guide device described in the above embodiments, and is not described again.
