[0002]

2. Description of the Related Art Generally, various types of mounting structures are employed for a battery mounting structure of a vehicle according to the type of the vehicle. For example, in a working machine such as a tractor, a battery is mounted below a driver's seat. Often.

For example, as disclosed in Japanese Utility Model Publication No. 3-43082, a battery is disposed in a space covered with a frame cover below a driver's seat, and a battery is opened and closed on a front wall portion of the frame cover. A flexible lid is provided, and the lid is pulled out to the step side by holding the lid with a hand and being pulled out forward, so that the battery is integrated with a battery receiving stand connected to the inner surface of the lid. ing.

[0004]

According to such a conventional structure, there is an advantage that the battery can be easily pulled out and pushed in, but on the other hand, every time battery maintenance is performed,
Attachment and removal of the lid from the frame cover by attaching and detaching bolts are required, and the structure of the battery storage unit itself becomes complicated.

Although the battery can be easily pulled out and pushed in, the wiring connection operation to the battery terminal is performed with the battery pulled out. Special care must be taken to prevent wiring errors due to the reverse of the above.

Further, since the wiring connection is performed in a state where the battery is pulled out, it is necessary to provide a thick battery cable with a sufficient length.

The present invention has been made in view of the above circumstances, and allows a battery to be easily and reliably mounted, has a simple structure, does not easily cause erroneous wiring connection to a battery terminal, and requires a thick battery cable more than necessary. It is an object of the present invention to provide a vehicle battery mounting structure which does not need to be secured for a long time.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, a battery mounting structure for a vehicle according to the present invention is formed integrally with a predetermined portion of the vehicle, has a flat rectangular shape with an open upper surface, and has a front wall and left and right side surfaces. A battery storage box made of a synthetic resin in which the wall is substantially vertical and the rear wall gradually inclines rearward from the lower end toward the upper end, and is provided on at least one of the front wall inner surface or the left and right side wall inner surfaces of the battery storage box. A stopper that extends to a front upper surface portion of the battery stored in the battery storage box and suppresses upward movement of the battery; and a left and right side wall of the battery storage box includes a stopper for the battery. A connection line that is connected to a terminal of the battery from the outside of the battery storage box is inserted in a position facing the rear side of the left and right side surfaces. It is characterized in that the formation of the connection line through-hole.

[0009]

The front wall and the left and right side walls of the battery storage box are perpendicular to each other, and the rear wall is gradually inclined rearward from the lower end toward the upper end. Thus, the battery can be easily and reliably stored in the battery storage box from the upper opening. In addition, since the stopper in the battery storage box extends to the upper surface portion on the front side of the battery, the stopper can prevent the battery from rising upward when the vehicle body largely moves up and down. Also,
If the battery is stored in the battery storage box with the front and rear directions reversed from normal, the stopper may interfere,
Since the connection wire does not reach the terminal and the connection wire cannot be connected to the battery terminal, incorrect wiring can be prevented. Furthermore, since the connection wires can be inserted into the connection wire insertion holes in the left and right side walls of the battery storage box and arranged and connected to the terminals of the battery, it is not necessary to secure a thick battery cable longer than necessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of a riding lawn mower as an example of a vehicle to which the present invention is applied. In the drawing, reference numeral 1 denotes a riding lawn mower (working machine). Frame cover 3 is provided. As shown in FIGS. 2 to 5, a battery housing box made of synthetic resin is formed integrally with the frame cover 3.

The battery storage box 4 has a flat rectangular shape whose upper surface is open, and has a front wall 4a and left and right sides.
The right side walls 4b and 4c are substantially vertical, and the rear wall 4d is gradually inclined rearward from the lower end toward the upper end. The battery storage box 4 is located in the frame cover 3, and an upper edge 4 e thereof is integrally connected to the frame cover 3 via a connection wall 5. The upper opening of the battery storage box 4 is opened and closed by the driver's seat 2. Then, the battery 6 having a rectangular parallelepiped shape can be stored in the battery storage box 4 from the upper opening that is opened by rotating the driver's seat 2 upward. The shape of the bottom surface 4f of the battery storage box 4 is substantially the same as the planar shape of the battery 6.

A pair of stoppers 7 are integrally formed on the inner surface of the front wall 4a of the battery storage box 4 to protrude therefrom. These stoppers 7 have a tongue shape projecting substantially horizontally toward the rear and extend to the upper surface 6b on the front surface 6a side of the battery 6, so that the battery 6 when the vehicle body is largely moved up and down.
Is prevented from rising upward.

On the front wall 4a of the battery storage box 4, a ventilation window 8 which is elongated in the vertical direction corresponding to each stopper 7 is provided.
These ventilation windows 8 communicate the inside and outside of the battery storage box 4. These ventilation windows 8 are formed by punching holes of each stopper 7.

Left and right side walls 4 of battery storage box 4
In b and 4c, square connection line insertion holes 9 and 10 are formed facing the rear sides of the left and right side surfaces 6c and 6d of the battery 6, respectively. Then, connection wires 13 and 14 arranged and connected to the terminals 11 and 12 of the battery storage box 4 are inserted into the connection wire insertion holes 9 and 10, respectively.

In FIG. 1, reference numeral 15 denotes a vehicle body frame;
Is a front wheel, 17 is a rear wheel, 18 is a steering handle, 19 is a cutter deck, and 20 is a power transmission mechanism for transmitting engine power to a cutter (not shown) in the cutter deck 19.

In the above configuration, the front surface 6 of the battery 6
a in the battery storage box 4 with the a facing forward,
The battery 6 is housed through the upper opening. Then, the battery 6 is guided by the inclined surface of the rear wall 4d of the battery storage box 4, descends while gradually moving forward, and is placed and stored on the bottom wall 4f. In this stored state, as shown in FIGS. 3 to 5, the terminals 11 and 12 face the connection wire insertion holes 9 and 10, respectively, and the stoppers 7 are located above the front part of the upper surface 6 b of the battery 6. . The movement of the battery 6 back and forth and left and right is suppressed by the front and rear walls 4a and 4d and the left and right side walls 4b and 4c of the battery storage box 4, respectively. In addition, the upward movement of the battery 6 is suppressed by the stoppers 7, so that the battery 6
There is no danger that the terminals 11 and 12 will short-circuit between the terminals 11 and 12 due to the contact of the terminals 11 and 12 with the metal part under the driver's seat 2.

One terminal (cathode terminal) 11 of the battery 6 housed in the battery housing box 4 in this way.
The left side wall 4 from outside the battery storage box 4
One connection line (earth cable) 13 inserted into the connection line insertion hole 9 in b is connected using a bolt 21 and a nut 22. The other terminal (anode terminal) 12 of the battery 6
The right side wall 4 of the battery storage box 4 from outside.
The other connection wire (battery cable) 14 inserted through the connection wire insertion hole 10c is connected using a bolt 23 and a nut 24.

As described above, the mounting of the battery 6 is completed. After the completion, the driver's seat 2 is returned to the initial state, whereby the upper opening of the battery storage box 4 is closed by the driver's seat 2.

On the other hand, the battery 6 is connected to the front and rear walls 6.
When the batteries a and 6e are housed in the battery housing box 4 in a direction opposite to the normal state shown in FIG. 3, the bolt insertion holes of the terminals 11 and 12 of the battery 6 are closely opposed to the tips of the stoppers 7, respectively. Since the stoppers 7 hinder the bolts 21 and 23 from being inserted into the bolt insertion holes of the terminals 11 and 12, connection of the connection lines 13 and 14 to the terminals 11 and 12 becomes impossible.

Therefore, there is no possibility that the harness will be burned due to incorrect wiring (reverse connection).

When the battery 6 is stored in the battery storage box 4 in the opposite direction to the normal state as described above, the terminals 11 and 12 of the battery 6 are connected to the connection wire insertion holes 9 and 1.
0, the connection line insertion holes 9 and 1
The connection wires 13 and 14 inserted from 0 do not reach the terminals 11 and 12 because the connection wires 13 and 14 have no margin in length.
Connection of the connection lines 13 and 14 to the connection lines 1 and 12 becomes impossible.

Therefore, there is no possibility that the harness will be burned due to incorrect wiring (reverse wiring).

Further, the environment (temperature, air flow, etc.) in the battery storage box 4 is stabilized by the ventilation window 8 formed by using the die-cut hole of the stopper 7, so that an abnormal state due to dilute sulfuric acid gas or the like can be prevented. There is no danger.

[0025]

As described above, according to the battery mounting structure for a vehicle according to the present invention, the rear wall of the battery storage box is gradually inclined rearward from the lower end to the upper end, so that the inside of the battery storage box is inclined. The battery can be easily and reliably stored.

Also, the stopper inside the battery storage box can prevent the battery from jumping upward when the vehicle body largely moves up and down.

Further, when the battery is stored in the battery storage box with the front and rear directions of the battery reversed from the normal state, the stopper becomes a hindrance or the connecting wire does not reach the terminal. Cannot be connected, there is no possibility that the harness may be burned due to incorrect wiring.

Further, since the connection wire can be connected to the terminal by inserting the connection wire through hole, it is not necessary to secure a thick battery cable longer than necessary.
