Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric scooter technology, and in particular to a detachable electric scooter lithium battery pack assembly. Background Technology
[0002] Electric scooters are personal mobility devices powered by electricity. They are typically lightweight and flexible, suitable for short trips or leisure activities. Electric scooters move by an electric motor driving the wheels or transmission system, are usually powered by lithium batteries, and are operated via handlebars, motion controls, or remote controls.
[0003] Existing electric scooters typically use lithium batteries that are fixedly mounted on the central frame, employing a non-removable, integrated design. While this design ensures battery stability and waterproofing, it presents significant inconvenience during charging. Because the battery is completely integrated with the vehicle body, users must move the entire scooter to the charging socket to charge it, unlike removable batteries which can be taken out separately. This charging method not only limits the flexibility of charging while parked (e.g., making it impossible to carry the battery upstairs to charge in high-rise residential buildings) but also creates additional safety hazards due to vehicle movement (e.g., charging cables being run over by wheels). Furthermore, the charging area of the entire scooter occupies more space.
[0004] This invention provides a detachable lithium battery pack assembly for an electric scooter, allowing the battery pack to be easily removed for charging. This charging method is not only more flexible and convenient but also further improves charging safety and saves charging space. Utility Model Content
