Description

Technical Field

[0001] The utility model relates to the technical field of electric forklifts, and in particular to a battery compartment structure for a forklift. Background Art

[0002] The forklift battery needs to be charged after reaching a certain discharge amount. To ensure the continuous use of the electric forklift, the battery can be removed for charging and replaced with a set of spare batteries to continue to power the electric forklift.

[0003] At present, there are four main ways to replace electric forklift batteries: lifting, side pulling, side shoveling based on the fork sleeve, and side shoveling directly from the bottom of the forklift.

[0004] Lifting is the most common way to replace batteries, but it often requires a gap in the overhead guard to facilitate the entry of the lifting rope, and the user needs to configure a lifting structure to complete the replacement of the battery. Lifting will cause the cabin structure to be fragmented. Side pulling can make up for the shortcomings of lifting; but the existing side pulling requires the assistance of more complex supporting equipment. The side shoveling method based on the fork sleeve is to shovel by another forklift, but there is a problem that a large open area needs to be left on the side of the forklift for the work vehicle to turn, especially for large-tonnage forklifts equipped with batteries on both sides. The forklift needs to be parked in an area with open spaces on both sides, which is not conducive to management in the factory; and the bottom of the battery needs to be equipped with a fork sleeve or a pallet, which in turn causes the battery height to increase. The increase in the center of mass causes the dynamic stability of the forklift to decrease. At the same time, the bottom of the battery needs to be equipped with a fork sleeve or a pallet, which causes the battery compartment space to be maximized, increasing the difficulty of body layout. The side shoveling method directly from the bottom of the forklift not only has the disadvantage of the side shoveling method based on the fork sleeve requiring a large space on both sides, but also has the disadvantage that the forklift needs to leave the bottom completely empty, which increases the difficulty of ensuring the strength of the frame.

[0005] It can be seen that the replacement of electric forklift batteries currently has the following problems: the traditional lifting method requires a gap in the overhead guard; the bottom shoveling method requires the bottom of the forklift to be completely open, resulting in poor space utilization; the side-pull method has relatively fewer disadvantages, but there is currently a lack of corresponding battery compartment auxiliary transportation structure, resulting in high battery handling costs and overly complicated procedures.

[0006] In view of the problems existing in the prior art, there is an urgent need for a forklift battery replacement battery compartment structure that can assist the forklift in battery-assisted transport work when replacing the battery by pulling the battery from the side. Utility Model Content
