Abstract

The invention relates to the technical field of electric forklifts, in particular to an electric forklift battery pack and an assembling method thereof. The electric forklift battery pack includes a box body, a box cover and an electric core limiting frame, wherein the box cover is covered with the box body, and the electric core limiting frame is fixedly connected to the box body interior; a plurality of parallel gratings are arranged in the electric core limiting frame at equal intervals, parts in the electric core limiting frame are divided into a plurality of electric core inserting grooves by the gratings, and a plurality of electric cores arranged side by side are inserted into the electric core inserting grooves; insulation assemblies are all arranged in the circumferential direction and at the bottom of the electric cores, the electric cores are fixedly fastened in the electric core inserting grooves by limiting fastening parts arranged above the electric cores; and the electric cores are connected together in series by busbars. Secondary assembling of the electric cores is not needed by modules, the electric cores are packed directly by a battery pack structure, time is shortened, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of electric forklifts, in particular to an electric forklift battery pack and a method for assembling the battery pack. Background technique [0002] With the development of the economy, environmental protection, and the improvement of energy-saving requirements, electric forklifts are developing rapidly, especially in ports, warehousing, tobacco, food, textiles and other industries, electric forklifts are gradually replacing internal combustion forklifts and become the main force in fixed-range cargo handling. The electric forklift is driven by electricity, and the DC power provided by the battery pack drives each action motor. Compared with the internal combustion forklift, it has the advantages of no pollution, easy operation, energy saving and high efficiency. [0003] The battery cells in the traditional battery pack need to be assembled outside the battery pack first, and multiple battery cells are ass...
