Description

Technical Field

[0001] The utility model relates to the field of electric vehicle accessories, in particular to an anti-theft structure of an electric vehicle battery. Background Art

[0002] At present, most of the electric bicycles and electric scooters on the market have a large groove in the front half, that is, under the pedal, for placing the battery therein. After the power is turned on, the battery provides kinetic energy to the vehicle and the battery can be hidden therein. Since the battery of the existing electric bicycle is movably connected to the electric vehicle itself, the battery is often stolen by criminals when the person who stored the electric vehicle leaves. In order to prevent theft, people often take the battery away. However, the battery is not only heavy but also large in size, which is extremely difficult to carry, and it is easy for outsiders to pull out the battery, making it easy to be stolen.
