Description

Technical Field

[0001] The utility model belongs to the technical field of battery installation, and in particular relates to a battery pack shock-absorbing power generation device. Background Art

[0002] In the past, forklifts were mainly powered by internal combustion engines and lead-acid batteries. With the changes in the natural environment and the development of lithium-ion battery technology, lithium-ion batteries have gradually replaced traditional power sources with their environmental protection, no memory effect, and fast charging speed. Lithium battery packs have a high energy density and are relatively light overall. Therefore, in order to keep the forklift balanced when lifting cargo, most forklift manufacturers require the weight of the lithium battery pack to meet the required value when selecting a lithium battery pack for the vehicle. For battery manufacturers, designing an integrated and standardized battery pack and adding a separate counterweight block or counterweight box to the outside of the battery pack can effectively reduce costs and improve production efficiency. In addition, when the forklift is driving in the site, it will frequently vibrate due to factors such as uneven ground and heavy cargo. Excessive vibration or too frequent vibration will affect the welded connection rows and wiring contacts inside the battery pack, and even cause faults such as broken wires and desoldering. At present, most forklift lithium battery packs with added shock absorption functions use springs or rubber and other measures, such as a forklift lithium battery pack shock absorption device provided by the Chinese utility model patent with announcement number CN219998381U, which can only play a single shock absorption role and cannot recover the energy generated by vibration.
