Description

Technical Field

[0001] This invention belongs to the field of battery protection mechanisms, specifically a battery protection mechanism for a new energy forklift. Background Technology

[0002] New energy forklifts refer to forklifts powered by new energy sources, such as electric forklifts, hydrogen-powered forklifts, and solar-powered forklifts. Compared with traditional internal combustion engine forklifts, they have advantages such as environmental protection, energy efficiency, and safe operation. New energy forklifts are characterized by strong driving force, ease of use, stable performance, and zero pollution. The battery of a new energy forklift is the core component of its power system, which determines the forklift's range and performance. Currently, there are three main types of batteries used in new energy forklifts on the market: lithium batteries, lead-acid water batteries, and lead-acid dry batteries.

[0003] Existing patent, patent application number 202410540416.6, entitled "A Battery Protection Mechanism for a New Energy Forklift," has the feature that "the invention is fixed to the periphery of the protective shell via an inner shell, and the offsetting unit can be assembled on the inner shell. The offsetting side of the offsetting unit extends outward from the inner shell along the opening of the inner shell. After the offsetting shell is impacted, the offsetting unit can offset the impact, thereby improving the protective capability of the offsetting shell and making the battery inside the protective shell safer." However, it still has some shortcomings, such as it can only offset the impact force after an actual collision. When the battery protection device is not directly impacted, it may also cause impact to the battery, such as when the vehicle brakes or stops suddenly while it is moving, or when the vehicle itself is involved in a collision. Therefore, a battery protection mechanism for a new energy forklift is proposed. Utility Model Content
