Description

[Technical field]

[0001] The present invention relates to a water-proof structure for a vehicle battery, and more particularly to a water-proof structure for a vehicle battery arranged below a cowl grill and in front of an outside air inlet of a dash panel. [Background technology]

[0002] When introducing outside air into the air conditioning system of a vehicle, the outside air is introduced from an outside air inlet formed in the dash panel through a cowl grill arranged in the engine compartment to the air conditioning device. In addition, when water such as rainwater that has entered the engine compartment is drained, the water is also drained through the cowl grill. For this reason, it is preferable to place the battery in a position away from the cowl grill and the outside air inlet to prevent it from getting wet, but due to spatial restrictions in the engine compartment, it may be placed in front of the outside air inlet on the dash panel.

[0003] In Patent Document 1, in order to prevent the battery from becoming wet when the battery is disposed in front of the outside air inlet, a space for introducing outside air is disposed below the battery. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2018-69805 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, when space for introducing outside air as in Patent Document 1 cannot be secured due to spatial restrictions within the engine compartment, it is necessary to consider other structures for preventing water from getting into the vehicle battery. The cowl grill has a function of drawing in outside air for the air conditioner, as well as a function of draining rainwater, etc. Therefore, when the amount of outside air passing through the cowl grill is increased, the water in the cowl grill is vibrated by the air flow and splashes onto the inner surface of the cowl grill. If the battery is disposed below the cowl grill and in front of the outside air inlet, the splashed water runs down the inner surface of the cowl grill and falls and accumulates on the upper surface of the battery, raising the concern that the battery may become wet.

[0006] The present invention has been made to solve the problems of the conventional technology described above, and has as its object to reliably prevent a vehicle battery from becoming wet when the vehicle battery is disposed below the cowl grill and in front of the outside air inlet of the dash panel. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the present invention provides a vehicle body having a cowl grill including an outside air inlet for introducing outside air into the vehicle compartment, a dash panel separating the engine compartment from the vehicle compartment, a lower cowl grill, and an upper cowl grill covering the upper part of the lower cowl grill, a battery arranged below the cowl grill and in front of the outside air inlet, and a cover member covering the upper surface of the battery, wherein the upper cowl grill is provided with a first drainage channel extending in the vehicle width direction forward of the rear end of the cover member, and the cover member is provided with a second drainage channel located below the first drainage channel and extending to a position outside the outer casing of the battery, the first drainage channel has two ends, and at least one of the ends of the first drainage channel is arranged to overlap with at least a portion of the second drainage channel in a planar view.

[0008] According to the present invention configured as described above, the first drainage channel is provided in the upper cowl grill, the second drainage channel is provided in the cover member, and at least one end of the first drainage channel is arranged to overlap at least a part of the second drainage channel, so that water running along the inner surface of the upper cowl grill can be received by the first drainage channel, and the water drained by the first drainage channel can be further drained to the outside of the outer shell of the battery by the second drainage channel. Therefore, when the battery is arranged below the cowl grill and in front of the outside air inlet of the dash panel, the battery can be reliably prevented from becoming wet.

[0009] In the present invention, preferably, the upper cowl grill has a front inclined portion that slopes downward toward the front side and a rear inclined portion that slopes downward toward the rear side, and the first drainage channel is provided in either the front inclined portion or the rear inclined portion. According to the present invention configured in this manner, water running down the inner surface of the upper cowl grill is guided downward along the slope of the front inclined portion or the rear inclined portion, so that the water can be reliably guided to the first drainage channel.

[0010] In the present invention, preferably, the first drainage channel of the upper cowl grill is formed so that its length in the vehicle width direction is shorter by a predetermined length than that of the cover member and is positioned in the center of the cover member in the vehicle width direction, and the second drainage channel of the cover member includes a left drainage channel provided on the left side of the cover member in the vehicle width direction and extending in the vehicle width direction, and a right drainage channel provided on the right side of the cover member in the vehicle width direction and extending in the vehicle width direction, and at least one end of the first drainage channel is positioned so as to overlap at least a portion of the left drainage channel or the right drainage channel in a planar view. According to the present invention configured in this manner, the resistance experienced by the air flowing through the cowl grill can be reduced by the amount corresponding to the shortening of the length of the first drainage channel by a predetermined length. Also, water from the first drainage channel can be further received by the left drainage channel or the right drainage channel and drained to the outside of the outer casing of the battery. Therefore, the battery can be reliably prevented from becoming wet while reducing the resistance experienced by the air flowing through the cowl grill.

[0011] In order to solve the above-mentioned problems, the present invention provides a cowl grill having an outside air inlet for introducing outside air into the vehicle compartment, a dash panel separating the engine compartment from the vehicle compartment, a lower cowl grill, and an upper cowl grill covering the upper part of the lower cowl grill, a battery arranged below the cowl grill and in front of the outside air inlet, and a cover member covering an upper surface of the battery, wherein the upper cowl grill is provided with a first drainage channel extending in the vehicle width direction forward of the rear end of the cover member, and the first drainage channel extends in the vehicle width direction to a position outside the outer casing of the battery in a plan view.

[0012] According to the present invention configured as described above, the upper cowl grill is provided with the first drainage channel, and the first drainage channel extends to a position outside the outer casing of the battery, so that water running along the inner surface of the upper cowl grill can be received by the first drainage channel and drained to the outside of the outer casing of the battery. Therefore, when the battery is disposed below the cowl grill and in front of the outside air inlet of the dash panel, the battery can be reliably prevented from becoming wet. Effect of the Invention

[0013] According to the vehicle battery water damage prevention structure of the present invention, when the battery is disposed below the cowl grill and in front of the outside air inlet of the dash panel, the battery can be reliably prevented from becoming wet.
