As shown in FIGS. 1 and 2, the electric scooter 100 according to the present disclosure includes a frame 1, a battery 2, a pedal 3, and a control device 4. The battery 2 and the control device 4 are installed in different positions of the frame 1, and the pedal 3 The cover is arranged above the battery 2.

As shown in Figures 1 and 2, the frame 1 includes a chassis 5 and a support tube 6. The chassis 5 is formed with an upwardly open battery compartment 8. The battery 2 is housed in the battery compartment 8, and the battery 2 can be opposite to the battery compartment 8. When disassembled, the pedal 3 can be opened and closed at the open end of the upper part of the battery compartment 8, and the pedal 3 can be used by passengers to step on. It is understandable that when the power level of the battery 2 is low, the user or staff can remove the pedal 3, then take out the battery 2, and then place another fully charged battery 2 in the battery compartment 8, and finally put the pedal 3 Reinstall it on the chassis 5, so that the battery 2 replacement process can be completed.

Therefore, by providing a battery compartment 8 on the chassis 5 and a detachable pedal 3, the installation and disassembly of the battery 2 can be facilitated at least to a certain extent, the difficulty of replacing the battery 2 of the electric scooter 100 can be reduced, and the electric scooter 100 can be improved. The efficiency of battery replacement. Moreover, the pedal 3 located above can effectively protect the battery 2.

Optionally, as shown in FIG. 14, the bottom of the pedal 3 is provided with at least one reinforcing rib 59, which can extend in the length direction of the pedal 3, which can effectively and uniformly strengthen the structural strength of the pedal 3, thereby effectively It supports the user's body and can also effectively protect the battery 2. For example, there may be multiple reinforcing ribs 59, and multiple reinforcing ribs 59 may be arranged at intervals in the width direction of the pedal 3, so that the structural strength of the pedal 3 can be better strengthened. Among them, the number of reinforcing ribs 59 may be four.

As shown in FIGS. 1 and 2, the support tube 6 is provided at the front end of the chassis 5, and the support tube 6 is provided with an installation groove 7. The installation groove 7 can be used to install the control device 4, that is, the control device 4 is installed in the installation groove 7.
