On the other hand, the vehicle head 10 can be placed along the longitudinal direction of the vehicle frame structure 50, the distance in the transverse direction is reduced, and then the packaging space can be reduced, so that the packaging is more compact, and the space utilization is reasonable.

In another embodiment, the electric scooter 100 can be a folding type. As shown in fig. 9, the seat tube 51 may be folded toward the rear wheel 92 at the connection with the seat tube 521 of the front fork assembly 52. In order to fold the stand pipe 51 to facilitate lifting the electric scooter 100, the main body 20 is provided with a folding ring 25, a hook 94 is arranged on a rear mudguard 93 on the rear wheel 92, and the hook 94 hooks the end to end of the electric scooter 100 which can be folded after the folding ring 25, so that the electric scooter is convenient to carry.

Specifically, both ends of the folding ring 25 are connected to both sides of the handle holder 21, and the folding ring 25 can move up and down relative to the handle holder 21. Torsion springs 251 are further provided between both sides of the folding ring 25 and the main body portion 20 so that the folding ring 25 can be restored. The tip of the hook 94 is toward the rear end of the electric scooter 100.

After the stand pipe 51 is folded, the folding ring 25 touches the hook 94, so that the folding ring 25 moves upwards, and after the folding ring 25 reaches the hook tip end of the hook 94, the folding ring is automatically rebounded and reset through the torsion spring 251 on the folding ring 25, thereby achieving the effect of folding and fixing.

Preferably, the contact surface of the folding ring 25 and the hook 94 is inclined, and the distance between the lower end of the folding ring 25 and the hook 94 is smaller than the upper end thereof, so that the folding ring and the hook are hooked together more firmly.

The electric scooter 100 further includes a battery compartment, as shown in fig. 3 and 10, the battery compartment includes a housing assembly 6 and a mount 7, the housing assembly 6 being for accommodating a battery or a battery pack 81.

The supporting leg 650 at the rear end is formed by extending and bending the bottom of the rear cover 621, and the supporting leg 650 has a breaking portion 651, so that the engaging member 71 can be engaged in the breaking portion 651.

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.
