Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery packs, and more specifically, to a compact and lightweight lithium battery pack for a floor washer. Background Art

[0002] A floor washer, also known as a floor cleaning machine or a floor washing and drying machine, is a cleaning machine that can clean hard floors, suck up sewage at the same time, and take the sewage away from the site. It is suitable for places with broad hard floors such as stations, docks, airports, workshops, warehouses, schools, hospitals, restaurants, and shopping malls. The concept of cleaning with machines instead of manpower has taken root in people's hearts.

[0003] However, in the prior art, for the lithium battery pack applied to a floor washer, during actual use, due to the need for regular maintenance and the need to replace the battery at any time during high-intensity operation, the lithium battery pack often needs to be lightened to facilitate manual picking and placing, so as to extend the working cycle of the floor washer;

[0004] However, after the lithium battery pack is placed in the battery compartment of the floor washer, the wiring harness still needs to be manually inserted into the slot on the lithium battery pack, and the locking of the lithium battery pack is mostly carried out through the compartment door. When the compartment door is loose, the way the battery is placed in the battery compartment lacks stability, and in serious cases, it will lead to unstable power supply, posing a certain safety hazard.

[0005] In view of this, we propose a compact and lightweight lithium battery pack for a floor washer. Summary of the Utility Model
