Description

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 two-cell battery mounted on a vehicle.

[0002]

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

By the way, with the recent increase in on-vehicle electrical equipment, two batteries are often provided in order to enhance the power feeding ability. However, if two batteries are directly installed, they are adjacent to each other due to vibration input. This is not preferable because the batteries may crack due to friction or vibration between the batteries. Therefore, although an appropriate space is provided between the batteries, it is difficult to secure a sufficient space for installing the batteries in the engine room, and the space between the adjacent batteries becomes the minimum necessary.

Therefore, for example, as shown in FIG. 8, the adjacent batteries 5A and 5B are slightly displaced from each other in the longitudinal direction,
The pressing members 2A and 2B located along the upper surfaces of the batteries 5A and 5B are largely curved in the longitudinal direction from the center of the battery (deviation amount a), and the J bolts 4A to 4D are placed at positions where they do not interfere with the other battery. I am trying to join.

[0005]

However, in the above-mentioned conventional mounting structure, since one end of the pressing member is eccentrically larger than the center of the battery in the longitudinal direction (dimension a in FIG. 8), one side adjacent to each battery is The central part of the rim is insufficiently pressed down,
In particular, the holding of the battery was not sufficient for the vibration input from the left and right directions in FIG.

As shown by the chain line in FIG. 8, the holding member 2
It is also practiced to connect A and 2B and hold a pair of adjacent batteries at the center thereof with a single common holding member 2C, but with the battery tray 3 at the adjacent portion of the left and right batteries. Since there is no bond, retention tends to be insufficient.

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 reliably holding a two-by-two battery in a small space.

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

[0009]

In order to achieve the above object, the present invention provides a panel 3 in the invention described in claim 1.
A pair of batteries 5A and 5B are provided adjacent to each other with a small gap S therebetween, the lower end 18 is fixed to the panel 3, and the plate-shaped bracket 1 is erected in the small gap S and faces the bracket 1.

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) FIG. 1 shows an example of a mounting structure of the present invention. In the figure, a rectangular battery tray 3 serving as a panel
Above the left and right positions are rectangular parallelepiped batteries 5A,
5B is mounted. The batteries 5A and 5B are adjacent to each other with a small gap S therebetween and are displaced from each other in the longitudinal direction. A bracket 1 extending vertically is disposed in the center of the small gap S, and the bracket 1 is formed by bending a long metal plate body in the width direction. That is, the bracket 1 is provided with each battery 5
Horizontal walls 11 extending vertically in contact with one side edge 51 of A and 5B,
12 and a vertical wall 13 that connects the horizontal walls 11 and 12 and is orthogonal to each other so as to form a substantially Z shape, and a reinforcing rib 16 and a reinforcing flange 17 are bent and formed on both sides of the bracket 1. The lower half of the bracket 1 has a narrow width, and the lower end 18 of the bracket 1 is slightly bent so that the battery tray 3
Is fixed to the corrugated concave portion 31 formed on the plate surface with a screw.

The upper end of the bracket 1 is provided with each battery 5
A little extending from the upper surfaces of A and 5B, and locking holes 14 and 15 (FIG. 2) are provided in each of the lateral walls 11 and 12 at the upper ends thereof. On the other hand, holding members 2A, 2B extending substantially linearly across the batteries 5A, 5B are provided at the center of the upper surfaces of the batteries 5A, 5B, and one end 21 of each holding member 2A, 2B is bent downward in an L shape. Locking pieces 211 are formed, and the locking pieces 211 are formed in the locking holes 14, 1 of the bracket 1.
5 is inserted and locked (FIG. 2). Each battery 5A,
Each of the pressing members 2A, 2B located on the other side edge 52 of 5B.
The other end 22 is slightly bent along the side surface so as to hold the batteries 5A and 5B, and the other end 22 portion is penetrated by the upper ends 41 of the J bolts 4A and 4B reaching from below. The hook portion of the lower end 42 of each J bolt 4A, 4B is locked in a locking hole 321 provided in the outer peripheral edge flange 32 of the battery tray 3 that bends downward, and each pressing member 2A, 2B.
The upper end 4 of the J bolts 4A and 4B penetrating the other end 22 of B
The nut 43 is coupled to the 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 even in the small gap S between the left and right batteries 5A and 5B due to the restriction of the installation space. In addition, the vertical wall 13 maintains the predetermined distance between the batteries 5A and 5B. Then, in the respective locking holes 14 and 15 (FIG. 2) of the bracket lateral walls 11 and 12 arranged in the center of the small gap S,
By locking one end 21 of each of the pressing members 2A and 2B, both side edges 51 and 52 of each battery 5A and 5B can be linearly connected at the center to reliably hold them.

In the above embodiment, the pressing members 2A, 2
The other end 22 of B is connected to the battery tray 3 by the J bolts 4A and 4B, but this 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 the battery 5B as shown in FIG. The facing gap D between the upper end of the plate-shaped bracket 1 and the body panel P, which are attached in advance in a posture, becomes narrow. For this reason, 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. 4 in a slightly inclined posture so as not to interfere with the plate bracket 1. Yes, there is a risk that it will take time to install.

Therefore, in this embodiment, as shown in FIG. 5, the bracket body 10 and the lower end 18 of the plate-shaped bracket 1 are arranged.
Are separated from each other, and both are connected by a hinge 19. As a result, the bracket body 1
0 can freely rotate around the hinge pin 191 as shown by an arrow in the figure.

As shown in FIG. 6, when the lower end 18 of the plate-like bracket 1 is fixed to the corrugated recess 31 by screws and set on the tray 3, the bracket body 10 is in the upright position (X in the figure). Position) to a retracted position (Y position in the figure) 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 surface of the battery 5B,
As described in the first embodiment, the one end 21 of the pressing member 2B (FIG. 1) is locked in the locking hole 15 (FIG. 5) to hold the battery 5B.

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

[0025]

As described above, according to the inventions described in claims 1 to 3, it is possible to securely hold the two batteries at a time in a small space.

Further, according to the invention described in claim 4, in addition to the above effects, the battery mounting operation can be easily performed.
