Forklift lithium battery pack

Abstract

The invention relates to the technical field of forklifts, specifically to a forklift lithium battery pack, which comprises a shell, wherein an upper cover is hermetically clamped at the top of the shell, a cooling fan is embedded in the top of the upper cover, a circulating water shell is arranged in the inner cavity of the shell, a plurality of lithium battery grooves are formed in the top of the circulating water shell, a lithium battery body is arranged in the inner cavity of the lithium battery groove, one end of the bottom of the circulating water shell is connected with the water outletend of a first circulating pump through a first connecting pipe, the water inlet end of the first circulating pump communicates with a water tank, refrigerating sheets are arranged at the bottom of the inner cavity of the water tank, one end, away from the first circulating pump, of the water tank communicates with the water outlet end of a second circulating pump, the water inlet end of the second circulating pump communicates with the circulating water shell through a second connecting pipe, a limiting groove is formed in the outer side wall of the shell, a limiting block is arranged in theinner cavity of the limiting groove, a limiting plate is arranged at the bottom of the upper cover, a fixing groove is formed in the limiting plate, two clamping grooves are formed in the outer wallof the end, away from the limiting groove, of the shell, and two clamping blocks are arranged on the inner wall of the bottom of the upper cover. The forklift lithium battery pack of the invention isconvenient to disassemble and assemble and good in heat dissipation effect.

Description

Technical field [0001] The invention relates to the technical field of forklifts, in particular to a forklift lithium battery pack. Background technique [0002] Forklifts refer to various wheeled vehicles for loading and unloading, stacking and short-distance transportation of pallet goods. Technical parameters such as rated lifting weight, load center distance, mast inclination and other technical parameters are used to indicate the structural characteristics and working performance of the forklift. At present, forklifts mostly use lithium batteries as the power source of forklifts. The safety and reliability of lithium batteries are better in the application process. However, the lithium battery structure on the market is not easy to install and disassemble, which brings great inconvenience to maintenance personnel. Traditional lithium battery packs will generate a lot of heat during use, which will seriously affect the service life of lithium battery packs. The current lithiu...

Problems solved by technology

[0003] The purpose of the present invention is to provide a lithium battery pack for forklifts. By setting the snap-fit ​​connection between the casing and the upper cover, when installing and dismounting, it is only necessary to snap fit between the limiting groove and the limiting plate, so that the limiting The bit block and the fixing slot are snap-fitted, and the snap-in slot is snap-fitted with the snap block. When dismounting, you only need to manually buckle the upper cover up and down to become separated, which is convenient for inspection, maintenance and replacement of the lithium battery body. By setting the top of the circulating water shell, there is a A plurality of lithium battery slots, the lithium batteries can be placed in the lithium battery slots respectively, not only to place the lithium batteries shaking, but also to avoid the mutual extrusion and damage of multiple lithium batteries, so as to solve the problem of common lithium batteries proposed in the above background technology. The group is inconvenient to disassemble and install, the heat dissipation effect is not good, and the problem of shaking damage between multiple lithium batteries cannot be prevented
