Heavy load full-emergence type slideway

Abstract

The invention relates to a heavy load full-emersion slideway which comprises a skeleton of an inner box body of a battery, a pair of upper slideways, a pair of middle slideways, a pair of lower slideways and a lower skeleton of an outer box body; wherein, the pair of upper slideways are welded with the skeleton of the inner box body of the battery in parallel; the pair of lower slideways are welded with the lower skeleton of the outer box body in parallel; the pair of middle slideways are welded into a rectangle framework structure in parallel and arranged between the upper slideways and the lower slideways for bearing and being as the slideways as well. The slideway of the invention can lead a drawer type battery box to be fast pulled out; the maintenance can be carried out when the battery is completely pulled outside a drawer frame; the battery with heavy weight can be easily carried in an emergency and can be led to fall down to the ground as well as be pushed away easily; an accident is hard to happen; the slideway of the invention has the advantages of simple structure, reliable intensity and convenient maintenance.

Description

technical field [0001] The invention relates to a heavy-duty fully detachable slideway, belongs to the technical field of electric vehicles, and is used for a quick loading and unloading system of a power battery pack of an electric vehicle. Background technique [0002] The batteries of current electric vehicles (such as buses) are connected with wires between the battery cells, and are bare-packed in metal boxes. The power connection between each battery box is connected with a manual plug, which cannot realize the overall quick installation and quick disassembly, and cannot use the quick battery replacement method to expand the mileage, especially lithium batteries and other organic batteries, which are prone to misuse. If these batteries are popularized, safety conditions must be met to quickly separate the battery box from the car. The problem of quick loading and unloading of the battery box must be solved. [0003] The applicant is applying for "an automatic quick-i...

AI Technical Summary

Problems solved by technology

However, if the pull-out slideway used for this kind of drawer is simply used on the power battery pack of the electric vehicle, obviously it will not work.

Because, (1) the weight of the battery pack (250 kg) is too heavy; (2) once the drawer is pulled out, the battery pack is pulled out of the drawer frame, and it is difficult to move such a heavy battery pack. Accidents, harder to repair
