DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery mounting structure, and more particularly to a mounting structure suitable for mounting a double battery mounted on a vehicle.

[0002]

2. Description of the Related Art FIG. 7 shows an example of a conventional mounting structure for a vehicle-mounted battery. In the figure, a battery 5 having a rectangular parallelepiped is placed on a battery tray 3 along the bottom surface shape. A locking hole 321 is formed at the center of the left and right (only one is shown) of the outer peripheral flange 32 of the battery tray 3, and the lower end of the J bolt 4 is locked here. Each J-bolt 4 extends upward along both side surfaces of the battery 5, and a holding member 2 provided along the center of the upper surface of the battery 5 is connected to a threaded portion of the upper end 41 by a nut 43.

[0003] With the recent increase in on-board electric equipment, two batteries are often provided in order to enhance the power supply capability. However, if two batteries are installed directly in contact with each other, vibration input causes vibration in adjacent parts. The battery may be broken by friction or vibration between the batteries, which is not preferable. For this reason, an appropriate space is provided between the batteries, but it is difficult to secure a sufficient space for installing the battery in the engine room, and the space between adjacent batteries is as small as possible.

Therefore, as shown in FIG. 8, for example, adjacent batteries 5A and 5B are slightly shifted from each other in the longitudinal direction.
The holding members 2A and 2B located along the upper surfaces of the batteries 5A and 5B are greatly curved in the longitudinal direction from the center of the batteries (the amount of deflection a), and the J bolts 4A to 4D are positioned at positions where they do not interfere with the other batteries. To perform the join.

[0005]

However, in the above-mentioned conventional mounting structure, one end of the holding member is larger than the center of the battery and is eccentric in the longitudinal direction (dimension a in FIG. 8). The press at the center of the edge is insufficient,
In particular, it cannot be said that the battery is sufficiently held against the vibration input from the left and right directions in FIG.

[0006] As shown by a chain line in FIG.
A and 2B are connected to each other, and a pair of adjacent batteries is held at the center by a single common pressing member 2C. Lack of bonding tends to result in insufficient retention.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a first object of the present invention is to provide a battery mounting structure capable of securely holding a double battery in a small space.

It is a second object of the present invention to provide a mounting structure that facilitates the work of mounting a battery.

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) FIG. 1 shows an example of the mounting structure of the present invention. In the figure, a rectangular battery tray 3 as a panel
Above, the rectangular parallelepiped batteries 5A,
5B is placed. These batteries 5A and 5B are adjacent to each other with a small gap S, and are displaced from each other in the longitudinal direction. A bracket 1 extending in the vertical direction is disposed at the center of the small gap S, and the bracket 1 is formed by bending a long metal plate in the width direction. That is, each of the brackets 1 is
A, 5B, a side wall 11 extending vertically in contact with one side edge 51,
The bracket 1 has a vertical wall 13 which is orthogonal to the horizontal walls 11 and 12 so as to form a substantially Z-shape. The lower half of the bracket 1 has a narrow width at its lower half, and its lower end 18 is slightly bent to form the battery tray 3.
Are fixed to the corrugated concave portion 31 formed on the plate surface with screws.

The upper end of the bracket 1 has a battery 5
A and 5B extend slightly above the upper surface, and locking holes 14 and 15 (FIG. 2) are provided in each of the lateral walls 11 and 12 at the upper end. On the other hand, at the center of the upper surface of each of the batteries 5A, 5B, there are provided pressing members 2A, 2B extending substantially linearly across them, and one end 21 of each of these pressing members 2A, 2B is bent downward in an L-shape. Locking pieces 211 are formed, and these locking pieces 211 are connected to the locking holes 14, 1 of the bracket 1.
5 are inserted and locked (FIG. 2). Each battery 5A,
Each of the pressing members 2A and 2B located on the other side edge 52 of the 5B.
Is bent slightly along the side surface so as to hold the batteries 5A and 5B, and the upper end 41 of the J bolts 4A and 4B extending from below penetrates the other end 22. Each J-bolt 4A, 4B has a hook at the lower end 42 which is locked in a locking hole 321 formed in the outer peripheral flange 32 of the battery tray 3 which is bent downward.
Upper ends 4 of J bolts 4A, 4B penetrating the other end 22 of B
A nut 43 is connected to one screw portion.

According to this mounting structure, as shown in FIG. 3, the bracket 1 formed by bending the plate material can be sufficiently installed in the small gap S between the left and right batteries 5A and 5B due to installation space restrictions. At the same time, the vertical wall 13 maintains a predetermined interval between the batteries 5A and 5B. Then, in the locking holes 14 and 15 (FIG. 2) of the bracket side walls 11 and 12 disposed at the center of the small gap S,
By locking the respective ends 21 of the pressing members 2A, 2B, the side edges 51, 52 of the batteries 5A, 5B can be linearly connected at the center and securely held.

In the above embodiment, the holding members 2A, 2A
The other end 22 of B is connected to the battery tray 3 by J bolts 4A and 4B, but the connection structure is not particularly limited.

(Second Embodiment) In the mounting structure described in the first embodiment, when a vehicle body panel P such as a fender panel is located near a battery 5B as shown in FIG. The facing gap D between the upper end of the plate-shaped bracket 1 attached in advance and the body panel P is narrowed. Therefore, when mounting the battery 5B on the tray 3, it is necessary to carefully pass the battery 5B into the facing gap D from the direction shown by the arrow in FIG. There is a possibility that installation work may take time.

Therefore, in the present embodiment, as shown in FIG.
And the two are connected by a hinge 19. As a result, the bracket body 1 is
Numeral 0 is freely rotatable around the hinge pin 191 as shown by the arrow in the figure.

When such a plate-like bracket 1 is set on the tray 3 with the lower end 18 fixed to the corrugated recess 31 as shown in FIG. 6, the bracket body 10 is placed in the upright position (X in FIG. 6). ) Can be rotated and tilted from the position (A) to a retracted position (Y position in the drawing) separated from the body panel P.

Therefore, when installing the battery 5B,
The bracket body 10 is tilted to the retracted position Y. In this state, since the facing gap D is sufficiently wide, the battery 5B can be smoothly placed on the tray 3 in the hanging posture without interfering with the bracket body 10. After the battery 5B is placed, the bracket body 10 is rotated to the use position in the upright posture along the side of the battery 5B,
As described in the first embodiment, the battery 5B is held by locking the one end 21 of the pressing member 2B (FIG. 1) in the locking hole 15 (FIG. 5).

Note that, instead of the hinge of the present embodiment, another coupling structure that allows the bracket body to be tilted with respect to the lower end can be adopted. The tilting direction and the retreat position of the bracket main body are not particularly limited to this embodiment as long as they can avoid interference with the battery placed on the tray.

[0025]

As described above, according to the first to third aspects of the present invention, every third battery can be securely held in a small space.

According to the fourth aspect of the present invention, in addition to the above effects, the work of mounting the battery can be easily performed.
