Abstract

A battery lock device for a forklift includes a lock plate capable of moving between a first position and a second position. The lock plate at the first position is configured to keep a battery from being protruded. The lock plate at the second position is configured to enable the battery to be protruded. The battery lock device includes a shaft configured to rotatably support the lock plate with respect to a body, a fixed portion opposed to the lock plate, a lock pin capable of sliding toward the fixed portion in a first direction and away from the fixed portion in a second direction, and a spring configured to press the lock pin in the first direction. First and second holes are provided in the fixed portion. The lock pin is inserted into the first and second holes.

First claim

What is claimed is:

1. A battery forklift, comprising:
a battery housing formed in a body and configured to accommodate a battery; and
a battery lock device configured to keep the battery from being protruded out of the battery housing, wherein the battery lock device comprises:
a lock plate capable of moving between first and second positions, the lock plate disposed at the first position to keep the battery from being protruded, the lock plate disposed at the second position to enable the battery to be protruded;
a shaft configured to rotatably support the lock plate with respect to the body;
a fixed portion fixed on the body and opposed to the lock plate;
a lock pin capable of sliding toward the fixed portion in a first direction and away from the fixed portion in a second direction;
a spring configured to press the lock pin in the first direction; and
first and second holes provided in the fixed portion, the lock pin being selectively inserted into any one of the first and second holes; and wherein

the lock plate is locked at the first position when the lock pin is inserted into the first hole,
the lock plate is locked at the second position when the lock pin is inserted into the second hole, and wherein
the lock plate is moved between the first and second positions when the lock pin is withdrawn from the first and second holes, and the lock plate is extended in a horizontal direction when being disposed at the first position and in a vertical direction when being disposed at the second position, and wherein
the battery lock device comprises:
a protrusion mounted on the lock plate; and
a notch portion provided in the body and capable of engaging with the protrusion, and wherein the protrusion is engaged with the notch portion when the lock plate is locked at the first position.

2. The battery forklift according to claim 1 , wherein the lock plate comprises:
a first end portion supported by the shaft; and
a second end portion opposed to the first end portion, and wherein
the protrusion is provided at least at the second end portion.

3. The battery forklift according to claim 1 , wherein
the battery lock device comprises a sensor configured to detect whether the lock plate is disposed at the first position, and
the battery forklift comprises an alarm portion configured to alarm a driver when the sensor detects that the lock plate is not disposed at the first position.
