The front cover 611 is provided with a pressing cover 615, and the pressing cover 615 is used for pressing the handle belt to the front cover 611. The front cover 611 is further provided with a charging terminal 612, a discharging terminal 613, a power display panel 614 and a power display film 615, which are electrically connected to the battery or battery pack 81, and the charging terminal 612 and the discharging terminal 613 are used for charging and discharging the battery or battery pack 81 in the housing assembly 6.
A connecting seat 74 is disposed in the mounting seat 7, a power output port 741 is disposed on the connecting seat 74, and the power output port 741 is electrically connected to the discharging terminal 613 for discharging. The charging terminal 612 is externally connected with a power supply for charging, and a dust cover 614 is further arranged on the charging terminal 612.
The mounting base 7 is further provided with a cover plate 73, one end of the cover plate 73 is hinged to the mounting base 7, and the cover plate 73 can rotate relative to the mounting base 7 through the hinge, so that the mounting base 7 can be opened and closed to take and place the housing assembly 6.
A partition plate 72 is arranged in the mounting seat 7, the partition plate 72 has a step part 721, the cover plate 73 is provided with a telescopic lock 731, and when the cover plate 73 is covered on the mounting seat 7, the telescopic lock 731 is locked in the step part 721, so that the cover plate 73 is locked.
Specifically, a key hole is formed in the cover plate 73, a spring is further disposed in the telescopic lock 731, and after the key is inserted into the key hole and rotated, the spring can be pushed to enable the telescopic lock 731 to be clamped into the step portion 721 of the partition plate 72.
The electric scooter 100 using the battery compartment can prevent the battery or the battery pack 81 from being stolen, and can also ensure the use safety of the battery or the battery pack 81.
The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
