DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0019]
1 to 5, reference numeral 1 denotes a battery tray for mounting and supporting a battery at one side in the vehicle width direction of the engine room ER.
[0020]
The battery tray 1 is made of a suitable synthetic resin material, and includes a tray portion 2 that supports the battery 8 substantially horizontally, and a bracket portion 3 that extends downward on one side edge of the tray portion 2. The battery tray 1 is joined to the lower end portion of the hood ridge panel 5 constituting the side partition of the engine room ER, and the bracket portion 3 is superposed on the side surface of the front side member 6 constituting the vehicle body strength member in the front-rear direction. Thus, the front side member 6 is fastened and fixed to the front side member 6 via the bracket 3 by bolts and nuts 7.
[0021]
In this embodiment, a concave portion 4 projecting downward is formed in the central portion of the tray portion 2, a bush mounting hole 4 a is provided in the bottom wall of the concave portion 4, and a rubber bush 9 is fixedly fixed to the bush mounting hole 4 a. Thus, a connecting pin 11 projecting upward on a side portion of the engine unit 10 is inserted into the rubber bush 9 so that one side portion of the engine unit 10 is supported in an anti-vibration manner.
[0022]
Here, the battery tray 1 is integrally formed with an outside air introduction duct 12 connected to an air cleaner 15 and taking in outside air.
[0023]
In the present embodiment, the outside air introduction duct 12 is integrally formed with the battery tray 1, and a first duct 13 having duct fitting portions 13 </ b> A and 13 </ b> B formed at the front and rear ends, and a duct fitting on the front side of the first duct 13. The second duct 14 is connected to the portion 13 </ b> A and disposed in front of the first duct 13.
[0024]
The outside air introduction duct 12 is formed in a rectangular cross section, and the first duct 13 is integrally formed on the upper part of the bracket part 3 of the battery tray 1. In this embodiment, the upper part of the bracket part 3 is formed on the duct side wall. The upper surface of the first duct 13 is aligned with the upper surface of the tray portion 2 so that the upper surface of the first duct 13 is integrally formed.
[0025]
The duct fitting portion 13A on the front side of the first duct 13 is formed with its end face inclined so that the lower edge protrudes forward with respect to the upper edge, while the duct fitting portion 13B on the rear side The duct connector portion 15A provided on the lower surface side of the air cleaner 15 is fitted and connected from above by bending upward.
[0026]
1 and 2, reference numeral 15B denotes an intake manifold connector provided on the side of the air cleaner 15, and 16 denotes an engine hood.
[0027]
According to the structure of the above embodiment, since the outside air introduction duct 12 is integrally formed on the battery tray 1 that is firmly fastened to the front side member 6 and supports the battery 8, the outside air introduction duct 12 is attached. Therefore, it is not necessary to provide the fastening member for the duct side and the side member side. Therefore, the number of parts and the number of assembling steps can be reduced, and the cost can be advantageously obtained.
[0028]
Further, since the outside air introduction duct 12 is integrally formed with the battery tray 1 as described above, the outside air introduction duct 12 does not interfere with the battery 8, and accordingly, the battery is considered in consideration of avoiding interference with the battery 8. Therefore, it is not necessary to reduce the duct diameter for the purpose of securing a required clearance between the two and the duct 8, and the duct diameter can be sufficiently ensured to increase the outside air introduction efficiency.
[0029]
In particular, in the present embodiment, the outside air introduction duct 12 can be disposed by effectively using the space above the front side member 6, and the space efficiency in the engine room ER in a limited space can be improved. Since the outside air introduction duct 12 is integrally formed with the upper portion of the bracket portion 3 of the battery tray 1 as a part of the duct side wall in addition to the duct arrangement above the front side member 6, the duct diameter can be increased. The outside air introduction efficiency can be further increased.
[0030]
Further, in this way, for example, when the same duct cross-sectional area is obtained by integrally molding the outside air introduction duct 12 with the upper portion of the bracket portion 3 as a part of the duct side wall and expanding the duct diameter, the phantom line in FIG. As shown in the phantom line of the figure, the battery mounting height is increased by increasing the duct height as compared with the case where the outside air introduction duct 12 is formed by separating the bracket portion 3 and increasing the duct height. As the height increases, the hood height of the engine hood 16 does not increase, so that there is no hindrance to the shaping of the front portion of the vehicle body.
[0031]
In particular, the outside air introduction duct 12 has an upper surface aligned with the upper surface of the tray portion 2 of the battery tray 1, so that the battery support surface can be advantageously ensured in terms of design and layout. Similarly, it can be avoided that the duct height of the outside air introduction duct 12 is higher than the battery support surface and the hood height is increased.
[0032]
Further, in the present embodiment, the outside air introduction duct 12 is constituted by a first duct 13 integrally formed with the battery tray 1 and a second duct 14 connected and disposed in front of the first duct 13. 8 can be formed so as not to interfere according to the layout of various parts in front, the degree of freedom of modeling of the outside air introduction duct 12 can be increased, and by preparing several types of second ducts 14, It is possible to deal with different types of vehicle layouts in front of the battery 8, which is further advantageous in terms of cost.
[0033]
Further, the rear end portion of the second duct 14 is placed on the lower edge portion protruding forward of the duct fitting portion 13A on the front side of the first duct 13, and the second duct 14 is used as the insertion guide by using the lower edge portion as an insertion guide. In addition to being able to be easily inserted and connected to one duct 13, the duct connect portion 15 </ b> A of the air cleaner 15 can be dropped and connected to the upward duct fitting portion 13 </ b> B on the rear side of the first duct 13. These connection operations can be easily performed.
