[0002]

2. Description of the Related Art Conventionally, as a battery support structure for a vehicle such as a cab-over truck, for example, a structure as shown in FIGS. 10 to 12 is known.

That is, as shown in FIGS. 10 to 12, of a body frame (side frame) 2 arranged below the body 1a along the front-rear direction of the body 1, a portion near a front end in an engine room 3 is provided. A support plate 4 projects outward from the upper surface.

[0004] A bracket 6 is fixed to a tip end portion of the support plate 4 protruding outwardly by a bolt 7 and a nut 8 with a body mount insulator 5 interposed therebetween as shown in FIG. Has been established.

The bracket 6 has a bottom plate portion 6a in the shape of a saucer.
And a channel portion 6b having an inner wall lower end fixed to the periphery of the edge of the bottom plate portion 6a and projecting upward. By fixing the inner wall of the channel portion 6b to the outer wall of the hood ridge panel 9, the vehicle body frame 2 supports the body 1a.

A battery bracket 10 is arranged inside the engine room 3 of the hood ridge panel 9 along the shape of the hood ridge panel 9.

Referring to the drawings according to the present invention, as shown in FIG. 5, a battery 13 and a battery 13 are provided on an upper surface 10a of the battery bracket 10.
Is mounted on the cover 13a.
Moreover, the battery 13 and the cover 13a are fixed by the fix rod 11, the bar 12, and the like. The upper edge of the battery 13 is provided with a flange 13b that comes into contact with the upper surface of the battery 13.

The channel portion 23b has the side wall portions 23c, 23c and the lower end side inner wall of the back surface portion 23d fixed around the edge of the bottom plate portion 23a.

The bottom plate 23a of the mounting member 23
An insulator 24 (see FIG. 2) is interposed on a tip end side 22a of the vehicle body frame 22 and is fixedly mounted by bolts 25 and nuts 26.

The side wall 23 of the mounting member 23
d is fixed to the inner wall of the radiator core support panel 20, and the back surface 23 e is fixed to the inner wall of the hood ridge panel 21.

As described above, the channel portion 23b is connected to the radiator core support panel 20 and the hood ridge panel 2.
1 is fixed to the inner wall of the vehicle body frame 2.
2 supports the vehicle body 18.

In the vicinity of the mount member 23, a battery bracket 27 made of a panel is disposed on the step portion 21a of the hood ridge panel 21. The upper surface portion 27a (battery mounting surface) of the battery bracket 27 extends substantially horizontally and has an area secured on the assumption that the battery 13 has the maximum capacity.

The projecting portion 27b of the battery bracket 27 is connected to the engine room 1 above the body frame 22.
9 so as to protrude from the step 21a.

The front and side edges of the upper surface 27a have a first flange 27 bent substantially vertically upward.
The upper surface portion 27a is formed in a tray shape.

The portion of the first flange portion 27c corresponding to the mount member 23 is the other first flange portion 27.
A wide portion 27d wider than the portion c is formed, and the wide portion 27d is formed on the side surface portion 23 of the mount member 23.
c is fixed by spot welding. The side surface 27e of the first flange 27c is fixed to the vertical wall 21b of the hood ridge panel 21 by spot welding.

Further, the side wall 27f of the overhang portion 27b
Extends substantially downward to extend the stepped portion 2 of the hood ridge panel 21.
1a is fixed to the portion below the battery
And the step 21a of the hood ridge panel 21
Constitutes a closed cross section. Then, the side wall 27f
At the front edge, a second flange portion 27g bent substantially perpendicularly to the side wall 27f is formed. The second flange portion 27g is fixed to the side surface portion 23c of the mount member 23d by spot welding.

Reference numeral 28 in FIG. 2 denotes a reinforcement.

Next, a configuration in which the battery 13 is disposed on the battery bracket 27 will be described.

FIGS. 5 to 7 show a configuration in which the battery 13 is disposed on the bracket 10. FIG.

That is, the battery 13 covered by the battery cover 13a is placed on the upper surface 10a of the battery bracket 10.

Then, the upper surface 1 of the battery bracket 10
Locking pieces 10d, 10d having locking holes 10c, 10c are formed below the insertion holes 10b, 10b formed in the fixing rod 11, and the lower end hooks 11a,
11a is locked in the locking holes 10c.

The upper ends of the fixed rods 11, 11 are connected to both ends of the bar 12 by screwing nuts 29, 29, and the battery 13 is fixed to the battery bracket 10.

However, in such a configuration in which the battery 13 and the battery cover 13a are disposed on the bracket 10, the side wall 13b of the battery cover 13a as shown in FIG.
Of the battery 13 and the battery cover 13a, and there is a problem that the space 30 between the battery 13 and the battery cover 13a cannot be kept constant.

In this embodiment, as shown in FIGS. 8 and 9, hook-shaped projections 32 and 33 are formed on the side wall 31b of the battery cover 31 so as to be locked on the fixed rod 11. I have to.

That is, in the embodiment shown in FIG. 9A, the locking hook-shaped projection 32 is formed by cutting out the side wall 31b of the battery cover 31.

In the modified example shown in FIG. 9B, a hook-shaped projection 33 for locking is integrally formed on a side wall 31b of the battery cover 31.

Next, the operation of this embodiment will be described.

First, when the battery 13 is mounted on the battery bracket 27, the battery 13 is guided by the first flange portion 27c because the upper surface portion 27a has a tray-like shape by the first flange portion 27c. It is easy to perform positioning.

Further, the wide portion 27d of the first flange portion 27c, which is a part of the battery bracket 27, and the second flange portion 27g of the side wall 27f are fixed to the side surface portion 23c of the mount member 23. The projecting portion 27b of the battery bracket 27 on which the weight of the battery 13 acts most is directly fixed to the body fixing mount member 23, and the supporting rigidity of the battery 13 is high.

Therefore, compared to the conventional battery support structure, the thickness of the battery bracket 27 can be reduced and the number of spot weldings can be reduced as a whole, thereby suppressing an increase in manufacturing cost and an increase in weight.
