Abstract

A working machine may include a battery box and a battery detachably attached to the battery box. The battery box may include a top cover, and a battery cover having a shape that covers the battery attached to the battery box and being pivotable about a pivot axis with respect to the top cover. When the battery box is viewed in a top plan view in an open state in which the battery cover is open, the battery cover and the top cover may at least partially overlap with each other. When the battery box is viewed in the top plan view in a closed state in which the battery cover is closed, the battery cover and the top cover may at least partially overlap with each other.

First claim

The invention claimed is:

1. A working machine comprising:
a battery box; and
a battery detachably attached to the battery box,
wherein
the battery box includes:
a top cover; and
a battery cover having a shape that covers the battery attached to the battery box, being provided with a hinge, and being pivotable about a pivot axis of the hinge with respect to the top cover,
when the battery box is viewed in a top plan view in an open state in which the battery cover is open, the battery cover and the top cover at least partially overlap with each other and an upper side of the hinge is covered by the top cover, and
when the battery box is viewed in the top plan view in a closed state in which the battery cover is closed, the battery cover and the top cover at least partially overlap with each other and the upper side of the hinge is covered by the top cover.

2. The working machine according to claim 1 , wherein when the battery box is viewed in the top plan view in the open state, the battery attached to the battery box and the battery cover overlap with each other.

3. The working machine according to claim 1 , wherein a recess extending along the pivot axis is formed on an upper portion of the battery cover and the hinge is arranged in the recess.

4. The working machine according to claim 1 , wherein the battery box further includes a water tray arranged inside the battery box and above the battery.

5. The working machine according to claim 1 , wherein an upper surface of the top cover and an upper surface of the battery cover are inclined with respect to a horizontal plane.

6. The working machine according to claim 1 , wherein the battery is usable in other electric devices.

7. The working machine according to claim 1 , wherein when the battery box is viewed in the top plan view in the open state, the battery attached to the battery box and the battery cover overlap with each other,
a recess extending along the pivot axis is formed on an upper portion of the battery cover and the hinge is arranged in the recess,
the battery box further includes a water tray arranged inside the battery box and above the battery,
an upper surface of the top cover and an upper surface of the battery cover are inclined with respect to a horizontal plane, and
the battery is usable in other electric devices.

8. The working machine according to claim 1 , wherein when the battery box is viewed in the top plan view in the open state and the closed state, an entirety of the upper surface of the hinge is covered by the top cover.

9. A working machine comprising:
a battery box; and
a battery detachably attached to the battery box,
wherein
the battery box includes:
a top cover;
a battery cover having a shape that covers the battery attached to the battery box and being pivotable about a pivot axis with respect to the top cover; and
a water tray arranged inside the battery box and above the battery,
when the battery box is viewed in a top plan view in an open state in which the battery cover is open, the battery cover and the top cover at least partially overlap with each other, and
when the battery box is viewed in the top plan view in a closed state in which the battery cover is closed, the battery cover and the top cover at least partially overlap with each other.
