Embodiment 3

[0054] Embodiment 3: An electric scooter

[0055] see image 3 , Figure 4 , Pic 4-1 , Figure 6 , The skateboard is made of extruded aluminum alloy profiles, which is easy to process. The partition rib not only acts as a partition, but also acts as a cover for increasing strength. When placed above the cavity, an aluminum alloy plate can be used, or a wooden or plastic molding plate can be used as a pedal and component protection. The AC and DC dual-purpose charger has the same circuit structure as that of Embodiment 1.

[0056] The above is the charging device of the scooter. The AC input terminal 1 is a power interface through which the scooter is connected to an AC power supply for charging. The DC input terminal 10 is a power input interface for charging the scooter with a 12V vehicle power supply. The anti-reverse connection protector 11 prevents electrical equipment from being damaged when the polarity of the DC input terminal is wrongly connected in an accident...
