Description

Technical Field

[0001] This utility model belongs to the field of lithium battery replacement technology, specifically, it relates to a quick replacement device for lithium batteries in low-speed vehicles. Background Technology

[0002] With increasing environmental awareness and the demand for energy conservation and emission reduction, low-speed vehicles, such as electric four-wheelers, are becoming increasingly widely used in daily life and short-distance transportation. Most of these low-speed vehicles use lithium batteries as their power source, which have advantages such as high energy density, long lifespan, and high charge / discharge efficiency. However, the relatively long charging time of lithium batteries somewhat limits the convenience of using low-speed vehicles.

[0003] Traditional replacement procedures typically require removing the lithium battery from the low-speed vehicle and then reinstalling the fully charged lithium battery in the low-speed vehicle. However, due to the need for transportation during the replacement process and the relatively large weight of the lithium battery, the battery transportation process can be quite complex in the critical steps of battery positioning and connection. This can easily lead to misalignment of the battery, resulting in improper installation and unstable connection between the battery pack and the vehicle. Poor connection can directly affect the vehicle's power transmission and even cause safety hazards such as power outages during driving.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
