Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vehicle body structure of a battery forklift.

[Prior Art] As shown in FIG. 4, a counterweight 2 is attached to a rear portion of a vehicle body 1, and a steering member such as a steering wheel 3 is attached to a front portion.
There is known a vehicle body structure in which the battery 4 is attached to the vehicle body 1 and the battery 4 is attached to an intermediate portion of the vehicle body 1, and the upper portion and both side portions of the battery 4 are covered with the upper hood 5 and the both side covers 6 and 6 without a gap.

With such a vehicle body structure, the driver's seat 7 can be installed in the upper space of the battery 4 to effectively utilize the vehicle body space, and the upper hood 5 and the both side covers 6 and 6 prevent dust and the like from entering the upper portion of the battery. It can be prevented.

[Problems to be solved by the invention] However, with such a vehicle body structure, the upper hood 5 and both side covers 6, 6 must be removed when the battery is replaced, which is very troublesome and the upper 7 hood. Since 5 and both side covers 6 and 6 are required, the number of parts increases and the cost increases.

[Means and Actions for Solving the Problem] In the present invention, an upper hood including an upper plate and a front edge piece and both side edge pieces provided on a peripheral edge of the upper plate is opened at a lower position to cover an upper portion of the battery. It is provided rotatably over the upper position, and a cutout for attaching and detaching the battery is formed on the rotation fulcrum side of both side edge pieces, and a door for opening and closing the cutout is provided to prevent dust and the like on the upper part of the battery. In addition, the battery can be easily replaced, the structure is simple, and the battery and both side edge pieces do not interfere with each other when the battery is removed.

[Example] A counterweight 11 is attached to a rear portion of the vehicle body 10,
A box-shaped battery case 12 whose upper part is opened is provided adjacent to the counterweight 11, and a battery 13 is placed and housed in the battery case 12. A steering member (not shown) and the like are provided at the front of the vehicle body 10.

14 is an upper hood, this upper hood 14, the front edge of the upper plate 15 and the front edge pieces 16 and both side edge pieces 17, 17 are integrally formed downward to strengthen the strength, The upper part of the battery, the upper part of the front part, and the upper parts of both sides are covered to prevent dust from entering the upper part of the battery 13, and the rear edge of the upper plate 15 is hinged to the vehicle body side, for example, the upper part of the counterweight 11.
The upper plate 15 is pivotally connected so as to be vertically rotatable, and the front edge side of the upper plate 15 is supported by a frame standing plate 19 standing on the body 10 of the vehicle body. is there.

A notch 20 for attaching and detaching the battery is formed at the rear portion of the both side edge pieces 17, that is, on the side of the pivot point, and a door 21 is provided in the notch 20.
Is attached by a hinge 22, and is normally fixed to a support plate 23 by a screw 24. Note that a magnet or the like may be used for fixing instead of using screws.

Then, when replacing the battery 13, the upper hood 14
As shown in FIG. 3, while rotating upward, the door 21
And the battery 13 is lifted by the rope 25 such as a crane and lifted from the battery case 12.

In this state, the battery 13 is moved to the side and removed. Even when the battery 13 is moved laterally, the notch 20 for attaching and detaching the battery is formed in both side edge pieces 17, and the door 21
Since the battery is open, the battery does not collide with and interfere with both side edge pieces 17 of the upper hood 14. When the upper hood 14 covers the upper part of the battery 10, the door 21 is closed and the battery 13
Can cover the upper side of the.

That is, as shown in phantom in FIG. 3, both side edge pieces 17
If the notch 20 is not provided in the battery 13, the battery 13 is lifted up, and the side edge pieces 17 interfere with the side surface of the battery 13 during lateral movement.
If you move the hinge 18 backward, both side edge pieces 17 and the battery 13
Although it is possible to prevent the side surfaces of the upper hood 14 from interfering with each other, the upper hood 14 becomes longer.

[Advantage of the Invention] According to the present invention, only the upper hood 14 in which the upper plate 15 is provided with the downward front edge piece 16 and the downward both side edge pieces 17,
It is possible to prevent dust and the like from entering the upper part of the battery 13, and the structure is simple and the cost is low, and the battery 13 can be replaced by rotating the upper hood 14 upward, which simplifies the work.

Moreover, when the battery 13 is lifted to the side and the side is lifted, the door 21 is opened and the notch 20 is opened so that the upper hood 14 is at the upper position.
Can be prevented from colliding and interfering with each other, and the side surface of the battery 13 can be completely covered by closing the notch 20 with the door 21 when the upper hood 14 is at the lower position.
