Abstract

A battery unit of an automated guided vehicle comprises a casing installed in a chassis of the automated guided vehicle, a battery housed in the casing, a control panel housed in the casing to monitor a charge and discharge state of the battery, and electric components housed in the casing and electrically connected to the battery. The battery is arranged in the casing such that a battery bottom surface is separated from the casing bottom surface.

First claim

1 .- 5 . (canceled)

6 . A battery unit of an automated guided vehicle, comprising
a casing installed in a vehicle body of the automated guided vehicle, a battery that is housed in the casing and has a hole penetrating in a vertical direction, a control panel housed in the casing and included in a charge/discharge monitor to monitor a charge/discharge state of the battery, electric components housed in the casing and electrically connected to the battery, a separating member arranged between the bottom surface of the battery and the bottom surface of the casing such that a bottom surface of the battery is separated from a bottom surface of the casing, and a bolt used to fix the battery to the casing while the bolt penetrates a hole of the battery and the separating member.

7 . The battery unit of the automated guided vehicle according to claim 6 , wherein the battery is configured by stacking a plurality of battery modules are comprised of a lithium ion battery, and a spacer is interposed such that a gap is formed between the neighboring battery modules.

8 . The battery unit of the automated guided vehicle according to claim 6 , wherein the casing is arranged in the automated guided vehicle such that a casing side wall surface is exposed to the outside,
a vertical wall bracket erected from the casing bottom surface is arranged inside the casing to face the casing side wall surface, the battery is arranged in a back side of the casing from the vertical wall bracket in a position distant from the casing side wall surface, the electric components are arranged in a near side of the casing from the vertical wall bracket in a position close to the casing side wall surface.

9 . The battery unit of the automated guided vehicle according to claim 8 , further comprising a horizontal beam bracket fixed to an upper side of the vertical wall bracket, and
a support plate provided in the horizontal beam bracket and arranged to cover an upper side of the battery, wherein the control panel is arranged on the upper surface of the support plate.

10 . The battery unit of the automated guided vehicle according to claim 6 , wherein the separating member is a cylindrical sleeve.
